Abstract

A communication device includes a controller (13) for transmitting parameters such as a maximum transfer rate and a maximum reception data length to a communication partner station by using an SNRM command without transmitting a station finding command (XID) for searching the communication partner station to a transmitter (1) for transmitting transmission data having a predetermined capacity by using infrared ray, and a transmission unit (14). This reduces the time required for establishing a connection between the transmitter and the receiver and reduces the time from a communication start to a communication end when information data is transmitted.

Description

Communication equipment, communication system, communication means, signal procedure, telecommunication circuit

Technical field

The present invention relates to the communication equipment that sends and receives, communication system, communication means, signal procedure, telecommunication circuit be used to the transmission of carrying out data.

Background technology

In recent years, additional cameras function on mobile phone, thus the view data of shot by camera is sent to the equipment such as television set, printer, and the application that this equipment carries out the processing of the regulation such as image Graphics Processing is popularized.

As the interface that connects mobile phone and television set, printer, PC (Personal Computer), the infrared mode (with reference to non-patent literature 1,2) of IrDA (Infrared Data Association) etc. is arranged.

The infrared mode of IrDA etc. owing to have directivity, thereby when having shelter between communication equipment, can not carry out the transmission of data, and the path between communication equipment can carry out data at a high speed and transmit when good.In the IrDA standard, it is that Fast IR (FIR), the communication speed of Very Fast IR (VFIR), the 4Mbps of 16Mbps is the following SIR of 115.2kbps that maximum transfer rate is arranged, and is product till the 4Mbps but the product of selling in the existing market is maximum transfer rate.

Figure 14 is illustrated in the IrDA standard of one of standard as infrared communication, the step till the connection of IrLAP layer is set up.

Main website is the station of at first searching for a side of communication counterpart, that is, be the station that data transfer state is set up in request, is the station of a side of dispatching station search command (XID order).And secondary station is the station of accepting this request, is that transmission is to the station of a side of the station search response (XID response) of station search command.To be called order to the request (order) at pair station from main website, on the contrary, will be for this order from the pair station replying of main website is called response.

The XID order is whether to have the order that can become secondary station in the interior search of the distance that can communicate by letter from main website.The SlotNumber of number is illustrated in and sends which order in the expression bracket.

The XID response as the station search response is beamed back at the pair station of having accepted the XID order, makes main website know the processing that our station exists.Main website sends the XID order of the number of regulation, and the SlotNumber of last XID order is made as 255.SlotNumber255 represents that it is last order (XID-END).

Then, but but main website uses the SNRM order to make secondary station know the parameter of the upper necessity of communication such as the maximum transfer rate of our station, maximum receive data length.The pair station of having accepted this order compares the set point of they and our station, uses the UA response and makes main website know acceptable set point.

If discuss in more detail, then following such.That is, in the IrDA standard, can select from 1,6,8,16 from the transmission number of the grouping of the XID of main website order, this value is recorded and narrated in the Discovery flag that XID orders.Then, for example, as shown in Figure 14, with the grouping of XID order is each when sending 8, from the 1st to the 8th till, make SlotNumber respectively from 0 to 7, make at last SlotNumber 255 send XID-END order, and be that the advisory of last grouping is as the pair station of remote station with it.Then, after sending last grouping, the time through about 500 milliseconds, repeat again to send the grouping from the 1st to the 8th.Have, the transmission between the grouping is spaced apart 25 milliseconds to 85 milliseconds again.

Secondary station is not that reception XID order just determines to beam back the XID response immediately, but after the grouping that receives the SlotNumber with any (value at random), beams back the XID response.For example, when sending the XID command packet of 8 time slots, secondary station can at random determine it is to beam back the XID response after receiving the 1st grouping, or beams back the XID response after receiving the 8th grouping.As an example, in Figure 14, be illustrated in the situation of beaming back the XID response after the 3rd grouping that receives.

Have, this XID order and XID response are determined to carry out with the transfer rate of 9600bps according to SIR by the IrDA standard again.This transfer rate is compared very slow with the 4Mbps of the transfer rate of Frame described later.Therefore, this XID order and XID respond to send and receive the required time long.Through above step, the station search step between main website and the secondary station finishes.

After the station search step finishes, but but main website uses the SNRM order to make secondary station know required parameter in the communication of the maximum transfer rate of our station, maximum receive data length etc.But but the pair station of having accepted this order uses the UA response to make main website know required parameter in the communication of the maximum transfer rate of our station, maximum receive data length etc., determined that but maximum transfer rate, maximum can transmit data length etc. thereby set up, the connection status of the IrLAP between main website and the secondary station.

After the connection based on the IrLAP of the command packet of above-mentioned IrLAP, by the packet of IrLAP, carry out the connection of IrLMP, Tiny TP, OBEX.

The connection request of the IrLMP of main website is sent to secondary station by the packet of IrLAP, and the IrLMP at secondary station connects the packet of replying by IrLAP and is sent to main website, carries out the connection of IrLMP.

Then, the connection request of Tiny TP is sent to secondary station by the packet of IrLAP, and the Tiny TP at secondary station connects the packet of replying by IrLAP and is sent to main website, carries out the connection of Tiny TP.

And then, the connection request of the OBEX of main website is sent to secondary station by the packet of IrLAP, the OBEX at secondary station connects the packet of replying by IrLAP and is sent to main website, carries out the connection of OBEX, thereby sets up the connection status that can carry out the transmission of information data.

When disconnecting, the disconnection request of OBEX and reply, the disconnection request of Tiny TP and reply, the disconnection request of IrLMP and the packet of replying by IrLAP transmit, then, transmission is as the DISC order of the disconnection request command grouping of IrLAP and the UA response of dividing into groups as acknowledgement command, and the communications status between main website and the secondary station is disconnected.

In addition, in IrDA, determine to communicate take frame as unit.The frame of expression IrDA among Figure 16.The frame of IrDA comprises: preamble field, start mark, address field, control field, data field, FCS, end mark.In above-mentioned field, preamble field is used for generating receiving terminal employed receive clock in receiving circuit.In addition, in FCS, comprise the error detection code for error detection occurs.

In frame, S (Supervisory) frame and the connection that is used for communication and U (Unnumbered) frame of disconnection that I (Information) frame that the information that is useful on transmits, the supervision that is used for communication are controlled.The information that is used for identification these I, S, U frame is included in above-mentioned control field.

Usually, because the data that are transmitted can not be in the majority with the situation that 1 frame sends, so send after being split into a plurality of I frames or UI frame.The I frame has the data that will transmit in data field, by having the consecutive number for the Missing data check, realize the high communication of reliability.The UI frame has the data that will transmit in the I field, but does not have the consecutive number for the Missing data check.The S frame is the structure that is not used for the data field of save data, be used for transmission receive be ready to complete, busy condition, re-send request may etc.The U frame does not have the such consecutive number of I frame, thus be called as non-number frame, be used for communication pattern setting, reply or the report of abnormality, foundation or the disconnection of data link.

[non-patent literature 2] Infrared Data Association Serial Infrared Physical LayerSpecification Version 1.4 (May 30,2003)

But in above-mentioned structure in the past, it is long that the generation data transmit the required time, the problem that transmission efficiency descends.

That is, as mentioned above, before the foundation of in IrDA, communicating by letter, need 500 milliseconds read (sensing), based on the station search of XID order, based on the exchange of negotiation (negotiation) parameter of SNRM, UA.

When in communication zone, having a plurality of communication station, in order to prevent the luminous phenomenon that hinders communication because of unexpected station, need to control the station in the zone.But, ultrared good directionality, in addition, in fact carrying out in the situation of infrared communication is One-to-one communication mostly, so also need to carry out the station search based on the automatic communication zone of equipment.

And, being defined as 9600bps based on the search of the station of this XID according to the IrDA standard, speed is more much lower than the speed of the 4Mbps of swap data.In addition, before transfer information data, as shown in figure 15, after the connection of having finished IrLAP, IrLMP, Tiny TP, OBEX are carried out the packet exchange of IrLAP successively, each layer sequentially need to be connected.Order with OBEX, Tiny TP, IrLMP, IrLAP disconnects similarly when disconnecting.

Because of above reason, transmitting with infrared ray the using method of data from a certain station information terminal to another station information terminal because until carry out the time that these data transmit and disconnect till time, so transmission efficiency as a whole descends.

In addition, image display device is being transmitted the using method of image from portable terminal, when in transmission, having produced mistake, sometimes can easily differentiate by the user and send unsuccessfully.For example, sometimes the demonstration of receiving terminal image display device and user send different, sometimes show not to be updated.

The user carries out transmit operation, if until can judge that the time that this transmission is success or failure is short, even the reliable communication that then is free from mistakes, the user can not produce large burden by operation again and again send yet sometimes.In such device, the reception that can carry out data is just passable, can save transtation mission circuit and device.

But, also beam back the response to order owing in IrDA, stipulated receiver, so transtation mission circuit and device need to be arranged in all receivers.

[summary]

(communication layers)

In execution mode described later, explain structure and the action of transmitter and the receiver of communication system of the present invention based on the OSI7 layer model.Here, the OSI7 layer model is also referred to as so-called ' OSI basic reference model ', ' OSI hierarchical mode '.

In the OSI7 layer model, in order to realize the data communication between different machines, the communication function that Computer application has is split into 7 layers, to the functional module of each layer definition standard.

Specifically, the 1st layer (physical layer) taken on for the electric conversion that data is sent to communication line or mechanical operation.The 2nd layer (data link layer) guarantees the communication path of physical property, and carries out the error detection occurs etc. of the data that flow at communication path.The 3rd layer (network layer) communicates the selection in path or the management of the address in the communication path.The 4th layer (transport layer) carries out data compression or error correction, repeating transmission control etc.The 5th layer (session layer) is for foundation or the release of the virtual route that sends and receives (connection) that communicates the data between the program.The 6th layer (display layer) will be the form that the user understands easily from the data transformation of the 5th layer of acceptance, will be the form that is suitable for communicating by letter from the 7th layer of data transformation that sends maybe.The 7th layer (application layer) will utilize the various services of data communication to offer people or other programs.

Each communication layers of the present invention also has the function identical with the corresponding layering of above-mentioned OSI7 layer model.But in execution mode, above-mentioned communication system is for forming session layer and display layer the structure of one 6 layerings.In addition, about application layer, description thereof is omitted.

The present invention can be widely used in that transmitter is connected the connection of a plurality of communication layers with receiver and the communication system that communicates.That is, cutting apart of communication function also can be according to the OSI7 layer model.In addition, if that the communication layers that connects has is a plurality of, then the number of communication layers can at random be selected.

In addition, the present invention can connect at short notice by the 1st agreement of having omitted the station search command, and by using the 1st agreement can suitably switch the 2nd agreement that can connect more reliably with being connected search command, disconnect easily so be particularly suitable for communication path, for example based on ultrared radio communication.But the present invention also is effective in other radio communications and wire communication.

LMP (S) accepts the connection request function from SMP (S), becomes the reception holding state.In addition, LMP (S) is from low layer (LAP (S)) when having accepted the connection notification function, extracts the parameter that the LMP (P) of transmitter generates from the data of function out, uses this parameter and finishes negotiation.Then, LMP (S) the connection request function that will add the data gained of the parameter of having removed LMP (P) from the data of above-mentioned function sends to SMP (S).

LAP (S) accepts the connection request function from LMP (S), becomes the reception holding state.In addition, LAP (S) is accepting SNRM when order from physical layer, extracts the parameter that the LAP (P) of transmitter generates from the data of SNRM order out, uses this parameter and finishes negotiation.Then, LAP (S) the connection request function that will add the data gained of the parameter of having removed LAP (P) from the data of above-mentioned function sends to LMP (S).

(3-2) exchanges data order

[A] has response

Figure 43 is the precedence diagram of the exchanges data order of expression present embodiment (response is arranged).And Figure 44 is the key diagram of data structure of communication data in exchanges data when order of expression present embodiment (response is arranged).

As shown in figure 43, present embodiment (response is arranged), transmitter produces the PUT order, and this order is transferred into low layer, and (Figure 37 (b)) is output as the UI frame.

On the other hand, receiver is accepted data, and high level is given notice.At this moment, at SMP (S), to the OBEX (S) of high level, notification data is (status=truncated) continuously.

Transmitter after the grouping that has sent certain fixed number, with confirm data whether the mark of complete arrival open (ON) and send.After receiving it, whether receiver has SMP (S) mistake, the number notifying transmitter of mistake will occur when mistake is arranged.

If be free from mistakes, the then next grouping of transmitter output, and if mistake is arranged, then transmitter is retransmitted the later grouping of grouping that mistake is arranged.

When becoming last data, transmitter is that the mark of last data is opened and sent with expression.To this, if being labeled as, this opens, then the SMP of receiver (S) gathers (status=OK) to OBEX (S) notification data, and waits for the response of OBEX (S).Then, when the response of OBEX (S) has occured, these data are sent to low layer, export as the UI frame.

If the response that receives is Success, then transmitter normal termination.

At transmitter, order sends function as data to OBEX (P) to low layer output PUT.But, the response (returning under normal circumstances Continue) of the PUT order beyond OBEX (P) does not need PUT Final (last PUT) order and can send with SMP (P) time, export Next Command.During order beyond PUT Final order or PUT order, wait for the data notification function from low layer, observe response in these data and the finish command.

Here, data transmission function is the function (Data Request) that the low layer request msg is sent.And the data notification function is to know the function (Data Indicate) that has received data from low layer.

At receiver, OBEX (S) accepts the data notification function from low layer, thus the data of acceptance.But OBEX (S) does not return response for the PUT order beyond the PUT Final order, in the situation of the order beyond PUT Final order or the PUT order, sends function and returns response as data.

Here, high level and the data transmission function of low layer and the head in the data notification function etc. that share in transmitter, the receiver are described.

SMP is when accepting data transmission function from OBEX, for LMP, when size that (a) can send with LMP sends data in the function big or small less than data, be the size that LMP can send with this Data Segmentation, when size that (b) can send with LMP sends size of data in the function greater than data, several data are carried out combination, the following larger data of size that formation can send.In addition, SMP forms the SMP head, this head be added into order number, to the independent variable of the last data of independent variable, the expression of the other side's equipment query data receiving state, expression the SMP of method, apparatus is needed whether normal independent variable of the independent variable of the response of OBEX, data that expression receives.Then, with added above-mentioned cut apart or the data of combination in the data of data gained after having added this SMP head send function and send to LMP.

And then SMP extracts the SMP head out the data in this function when accepting the data notification function from LMP, and confirms serial number whether normal (that is, whether sequentially arriving with omission not).Then, in normal situation, send the data notification function to OBEX.At this moment, the data notification function can be exported from the data notification function of low layer by each, output after also the data from the data notification function of several low layers can being merged.

It is to LMP that the SMP of transmitter (P) will send functional transformation from the data of OBEX (P)

(P) data send function, and the data that send certain data volume of fixing a number of defined send function.

Then, it is that True sends data transmission function that SMP (P) makes the independent variable to receiver data query accepting state, waits for the data notification function of LMP (P).

SMP (P) is to analyzing from the SMP head in the data notification function of LMP (S), in the data that receive of expression when normal independent variable is normally received, as the preparation that can send next data, become the state that can send OBEX (P).That is, under this state, can receive data from OBEX (P).

On the contrary, SMP (P) is analyzing the SMP head from the data notification function that receives of LMP (S), thereby in the data that receive of expression when normal independent variable is not normally received, send the function for the data that can not normally receive from notified, again produce data and send function, until make be True to the independent variable of the other side's equipment query data receiving state till.SMP (P) repeats again to produce data and sends function, until whole data send the notified receiver of data of function, perhaps repeats the again generation of certain stipulated number.

And, SMP (P) is that the independent variable of last data is that the data of True are when sending function having accepted from OBEX (P), the independent variable that makes this data of expression send the response of the independent variable that function is last data or the OBEX (S) that expression needs receiver is True, has been added into the data to LMP (P) that these data send the final data of function and sends function thereby send.

On the contrary, the SMP of receiver (S) is when having accepted the data notification function from LMP (S), needing the independent variable of response of the OBEX (S) of receiver in last data or expression is in the situation of True, send the data notification function to OBEX (S), this data notification function has added the data except the head of SMP (S).

In addition, SMP (S) is when having accepted the data notification function from LMP (S), and the data in this data notification function are analyzed the SMP head, and confirms serial number.If SMP (S) can normally receive before being the head of True accepting to the independent variable of receiver data query accepting state, then expression can normally receive for the data that receive of expression normal independent variable whether, thereby form the SMP head, and it is sent data transmission function as data to LMP (S).

On the other hand, detect can not normally receive the time at SMP (S), storage is predicted to be the number of the SMP head that can not normally receive.For example, receiving at 0,1,2,3,5 o'clock, the 5th should not receive in 4 the situation for 4, and being predicted to be the number that can not normally receive is 4.Then, after it, whether the independent variable to receiver data query accepting state that SMP (S) only investigates the SMP head is True, stops the output to the data notification function of OBEX (S).

SMP (S) is in the situation of data notification function of True having received to the independent variable of receiver data query accepting state, with the data independent variable whether normal independent variable can not normally receive as expression that represents to receive, the number of the SMP head that formation can not normally receive is inserted into the SMP head in the field of addition sequence number, sends function thereby it is sent data as data to LMP (S).

In addition, SMP (S) is in the situation of data notification function of True at the independent variable of the response of having accepted the independent variable that expression is last data or the OBEX (S) that expression needs receiver, after having exported the data notification function to OBEX (S), wait for the data sending request from OBEX (S).

SMP (S) is when the data sending request of having accepted from OBEX (S), the data SMP head whether normal independent variable can not normally receive that formation receives expression, it is attached in the data of data sending request of OBEX (S), sends function thereby LMP (S) is sent data.Have again, having in the situation of mistake, owing to stop notice to OBEX (S), be counted as being in when normal so wait to bide one's time.

Then, LMP when having accepted the data sending request function from high level, additional LMP head in the data in this function and form data, and LAP is sent the data sending request function that has added these data.In addition, LMP forms the data of having removed the LMP head the data in this function when having accepted the data notification function from LAP, and SMP is sent the data notification function that has added these data.

Have again, carrying out not needing to use LMP in the situation of a connection in mode one to one.In this case, in the LMP head, add the LSAP that connectionless value is arranged.

LAP is when having accepted the data sending request function from LMP, and the data in this function are added the LAP head and formed data, and physical layer is sent the UI frame that has added these data.In addition, LAP forms the data of having removed the LAP head from the data of this UI frame when having accepted the data receiver notice from physical layer, and LMP is sent the data notification function that has added these data.Have again, in present embodiment, in the LAP head, include link address and UI designator.

[B] is without response

As shown in figure 45, in present embodiment (without response), transmitter produces the PUT order, and this order is transferred into low layer, is output as the UI frame.

When becoming last data, transmitter is that the mark of last data is opened and sent with expression.To this, if being labeled as, this opens, then the SMP of receiver (S) gathers (status=OK) to OBEX (S) notification data, thus the end data exchange sequence.

At transmitter, order sends function as data to OBEX (P) to low layer output PUT.But OBEX (P) does not need just can the finish command to the response of all orders.Then, OBEX (P) exports Next Command in the situation that can be sent by SMP (P).

At receiver, OBEX (S) accepts the data notification function from low layer, and all orders are not returned response and only accepted data.

The SMP of transmitter (P) will be the data transmission function to LMP (P) from the data transmission functional transformation of OBEX (P).Then, be that the data of False send in the situation of function accepted independent variable as final data from OBEX (P), the data that will add the SMP head in these data send to LMP (P).On the contrary, SMP (P) is that the data of Ture send in the situation of function accepted independent variable as final data from OBEX (P), the independent variable that makes this data of expression send the response of the independent variable that function is last data or the OBEX (S) that expression needs receiver is True, thereby the data that send LMP (P) send function, and these data send the final data that function has added this data transmission function.

On the other hand, the SMP of receiver (S) is when having accepted the data notification function from low layer, and the data in this data notification function are analyzed the SMP head, the number of affirmation order.Then, SMP (S) analyzes the SMP head, thereby can confirm in the situation that can normally receive, and LMP (S) is sent data send function.

On the contrary, SMP (S) is detecting can not normally receive the time, and OBEX (S) notice has been produced mistake.For example, receiving at 0,1,2,3,5 o'clock, being the 5th should not receive 4 situation for 4.

Then, SMP (S) waits for that the independent variable of the response of the independent variable of the last data that represent the SMP head or the OBEX (S) that expression needs receiver is True, OBEX (S) is not carried out data notification, until data notification function (having again, even accept also not notify OBEX (S)) or the acceptance accepted as True disconnect till notification function or certain certain hour of process.

Then, the LMP of transmitter (P) when having accepted the data sending request function from SMP (S), additional LMP head in the data in this function and form data, and send the data sending request function that has added these data to LAP (P).

On the other hand, the LMP of receiver (S) is accepting from LAP (S) in the situation of data notification function, forms the data of having removed the LMP head the data in this function, and sends the data notification function that has added these data to SMP (S).

The LAP of transmitter (P) when having accepted the data sending request function from LMP (P), additional LAP head in the data in this function and form data, and send the UI frame that has added these data to physical layer.

On the other hand, the LAP of receiver (S) forms the data of having removed the LAP head from the data of UI frame, and LMP (S) is sent the data notification function that has added these data in the situation of having accepted the data receiver notice from physical layer.Have again, in present embodiment, in the LAP head, comprise link address and UI designator.

(4) have or not the switching of response

With reference to Figure 49～Figure 56, flowing of data between the communication layers of transmitter and receiver and parameter is described.

In present embodiment, transmitter is connected each communication layers LAP, LMP, SMP, OBEX and is had the connection request function, connects notification function, connects and reply function, connect and confirm function with receiver.These functions are the functions that the LAP layer conducted interviews for from high-rise (that is, LMP layer).

And above-mentioned function can specify Data (below, be designated as data) and Requested-Qos or Returned-Qos as independent variable.As described above, above-mentioned data are set in each communication layers.

On the other hand, appointment and the negotiation result notice of the consultation parameter of the baud rate that Qos will be determined by LAP etc. are high-rise, and high level has comprised OBEX.Have again, even Qos IrDA in the past also is used.

For example, when the application of transmitter or OBEX (P) sent the Qos added the parameter that needs/do not need respond, it was in turn transmitted to low layer until LAP (P).Then, LAP (P) is reflected the value of this Qos value as consultation parameter (Ack Less Connect), is sent to receiver.

Its result, each communication layers of transmitter and receiver is moved according to the appointment of the application of transmitter or the needs of OBEX (P)/do not need to respond, and can carry out twocouese/unidirectional connection.

Data between the communication layers when Figure 49～Figure 53 is the order of connection (Figure 40) of expression present embodiment (response is arranged) and the key diagram that flows of parameter.Have, the parameter of the QoS between OBEX-SMP, between SMP-LMP, between LMP-LAP can be identical again, also can be different.Therefore, in the drawings, attached Li Jia-a ,-b ,-c distinguishes.

At transmitter, as shown in figure 49, by con.req (data) (Figure 40), the Data that will send receiver and the data of QoS-1 (QoS of transmitter request) are transferred to low layer from high level.

On the other hand, at receiver, as shown in figure 50, by con.req, only the data with Qos-2 (QoS of receiver request) are transferred to respectively low layer from high level.

Then, at receiver, accepted moment of SNRM order at LAP (S), the relatively QoS-1 of transmitter and the QoS-2 of the machine form QoS-3 as the parameter of common connection.Then, shown in Figure 51, LAP (S) notifies high level with QoS-3 with the data from transmitter by con.ind (data).Each high-rise this QoS-3 of storage, the connection parameter during as connection is preserved.

Then, at receiver, when notice con.resp (data), do not need QoS.Therefore, shown in Figure 52, only data are transferred to low layer from high level in con.resp (data).Then, when LAP (S) accepts con.resp (data), in the UA response, add QoS-3, then send the UA response.

Then, at transmitter, LAP (P) accepts the UA response and QoS-3 is stored as the parameter that connects.Then, shown in Figure 53, LAP (P) notifies high level with QoS-3 with the data of receiver by con.conf (data).Each communication layers is preserved this QoS-3 as being established the connection parameter that connects.

In present embodiment, for example, as the QoS of con.req, use Requested-QoS:Baud-Rate+Max-Turn-Around-Time+Disconnect+ DataSize+Ack lessconnection+Min-Packet-Interval.And as Con.ind, the QoS of con.conf uses Resultant-QoS:Baud-Rate+Disconnect-Threshold+DataSize+Ac k less connection (indication primitive only).

In addition, when the order of connection (Figure 42) of present embodiment (without response), the data between communication layers and parameter mobile following such.

At transmitter, as shown in figure 49, by con.req (data) (Figure 42), the Data that will send receiver and the data of QoS-1 (QoS of transmitter request) are transferred to low layer from high level.

Then, the LAP of transmitter (P) directly stores QoS-1 as QoS-3.Then, shown in Figure 53, LAP (P) is high-rise with the QoS-3 notice by con.conf.Each communication layers is preserved this QoS-3 as the connection parameter of the connection of having established.

Then, at receiver, in the moment that LAP (S) has accepted the SNRM order, according to the QoS-1 of transmitter, set QoS-3.Have again, in the situation of the combination of the parameter that does not satisfy QoS-2 and QoS-1, can not receive.

Then, shown in Figure 51, LAP (S) notifies high level with QoS-3 with the data from transmitter by con.ind (data).Each high-rise this QoS-3 of storage, the connection parameter during as connection is preserved.

Thus, by using above-mentioned QoS-1 and QoS-2 are carried out high level (application) operation, can switch with/without response.

Here, as the switching benchmark with/without response, the file format of the file that consideration sends, application, user's selection etc.

Specifically, during take file format as benchmark, for example, in the situation of multimedia associated with, should select with/without response two sides, being the file of phone directory, mail, timetable etc. and will confirming in the received situation of data, also can automatically select response.In addition, when being applied as benchmark, in the situation that lantern slide shows, also can automatically select without response.In addition, in the situation based on user's selection, for example, the user from showing, the menu with/without response is selected.

The key diagram of the data between the communication layers when Figure 54～Figure 56 is the order of connection of expression present embodiment and the variation that flows of parameter.

In transmitter, in initial SNRM order, contain in the situation of information of all communication layers (Figure 40), also can constitute and not be that one side relaying in each communication layers transmits (Figure 49) on one side with data and parameter, but shown in Figure 54, data and parameter directly are transferred to the LAP layer from each communication layers.

On the contrary, shown in Figure 55, in receiver, also can constitute the data and the parameter that comprise in the SNRM order are all taken out, directly be transferred to as each communication layers that mails to the destination from the LAP layer.

In addition, shown in Figure 56, in transmitter, in the data and parameter set of LMP (P) with OBEX (P), SMP (P), LMP (P), and then by LAP (P) after above-mentioned concentrate data and parameter in append LAP (P) parameter, thereby generate the SNRM order.
