Description
Technical field
The present invention relates to a kind of method and system that is used for the call reverse charging business, more particularly, how collect the unified expense of call reverse charging for the position of realizing recipient's terminal no matter and/or type, the present invention relates to a kind of by free VoIP (Internet Protocol telephone) network with set up the method and system of the call link between caller and the recipient to the legacy network of recipient's charge.
Background technology
Traditional telecommunication service is the media of voice communication all the time, yet current telecommunication service has developed into the new tool that is used to provide various high-quality business.The purpose of telecommunication service provider is to provide the new telephone service that customizes according to user's request with low-cost and efficient now, and the most important thing is to obtain competition rather than a kind of hostile.As the Internet of the optimal solution of realizing this goal, become the indispensable part of daily life along with the sharp increase of number of users.Connection between PSTN (public switched telephone network (PSTN)) network and IP (Internet protocol) network is respectively cable business provider, mobile service provider, ISP (Internet service provider), equipment manufacturers and value-added information service provider various chances is provided.
Be devoted to provide Plain Old Telephone Service and the value-added service that before provided such as IETF (the Internet engineering duty group), ITU (International Telecommunications Union), ETSI standardisation bodies such as (ETSIs) by the PSTN network by the Internet always.IETF has proposed to be used on the internet the standard such as SIP (session initiation protocol), SDP (Session Description Protocol), MEGACO (MGCP), SIGTRAN (signaling transfer protocol) of the networking telephone and value-added service, and H.323 agreement is a kind of be used in the standard of packet networks on terminal between transmitting sound/data of ITU-T from the nineteen ninety research and development.In H.323, in order to have defined terminal, gateway, gatekeeper (gatekeeper) and four primary entities of MCU (multipoint control unit) at the enterprising row communication of network, and support TCP (transmission control protocol) and UDP (User Datagram Protocol) have been issued recently H.323v3.In order to cater to such as VoN (network-oriented voice, voice over network) demand of common solution such as, ETSI (ETSI) considers as SCN (switched circuit network, switched telephone network) and the technical problem that occurred when being connected to each other of the Internet, set up TIPHON (Telecommunications and Internet protocol Harmonization Over Network, the communication of network-oriented and Internet protocol merge) with standardization in order to develop.At present, in the VoIP standard, H.323 be most widely used.Figure 1A is depicted as the H.323 schematic diagram of the voip network of standard of basis.Pstn telephone 10b is by the calling of registered gateway 11a foundation to reception phone 13, and VoIP stand-alone phone 10a does not need gateway can set up receiving the calling of phone 13 yet.Call out/by called gateways 11a, 11b as the node that is used to insert heterogeneous networks with join based on the network phase region of H.323 standard and various criterion operation, and the data that will enter from a network and control signal convert to and are suitable for the network that mated.As based on the gatekeeper 12 of an entity of network H.323, will be bundled in the network predetermined portions that is called " district " such as a plurality of destination nodes of gateway, user side (PC, VoIP stand-alone phone), MCU (not shown) and carry out control/management/registering functional for the destination node that is arranged in the district.In based on network H.323, gatekeeper 12 is not a primary entity, but it can be carried out such as the main task of address transition, calling affirmation and bandwidth control and such as the generation and the charging attachments of a task such as (billing) of calling out control, statistics.Up to now, the professional used best charge system method of the voice telecommunication of having introduced in VoIP system is to adopt prepaid card.Prepaid card has such as cash, integration, mileage, reward voucher multi-form commutative values (exchangeable value) such as (coupon).Compare with PSTN network or mobile network, in voip network, have more calling subscriber and calling terminal, thereby be difficult to each calling is kept accounts respectively, so prepaid card is the most effective solution of voip billing system.But, though the operating cost of the voice telecommunication business of VoIP system all cheap than other any network, because the number of users that the user must buy prepaid card so VoIP before using voip network does not increase.In another approach, can adopt the form of back paying (postpaid) after the user signs a contract with the service provider before use.
Different with VoIP system, the collect call number of users increases faster in the PSTN network.Provided by the rapid PSTN service provider who reduces of user even the collect call business is originally by the development owing to mobile communication, but the mobile communication service provider provide identical business at present.Figure 1B is depicted as the telecommunication system of call reverse charging business.If the caller imports call reverse charging identifier and called number and called subscriber and accepted call reverse charging in phone 20a, 20b, the expense of call reverse charging is paid by the called subscriber so.For example, be PSTN user's called subscriber 25a on mobile phone, use the expense of mobile network and PSTN network all to pay so by the called subscriber if caller 20b calls out.Thereby the problem of traditional collect call business is that the expense of call reverse charging not only will but also will be calculated according to the type of calling terminal according to the type of called user terminal.
Fig. 1 C is depicted as the flow chart based on the conventional counsel service of ARS (Auto Response System automatic answering system).With reference to Fig. 1 C, in step 30, the user's (hereinafter referred to as " counsel user ") who seeks advice from that needs to pay dials its known telephone number.Charged counsel service among the PSTN/ mobile network provides by ARS, and has such as multiple systems such as destiny (fortune), stock, tax revenues.In step 35, when receiving call, several voice menus that ARS generation counsel user can be selected and the selection that receives the user.When in step 40 after connecting between counsel user and the selected consultant, counsel user must be explained its content that need seek advice from (hereinafter referred to as " essential information ") in step 45, and counsel user can be heard result's (hereinafter referred to as " consultation information ") of consulting in step 50 then.
Most ARS consulting system only begins to charge after calling is connected to the ARS consulting system.Select consultant and explain basic information to spend most of the time of charged counsel service, and if counsel user explain basic information exactly, will make the whole time lengthening of calling.And, therefore because the communication equipment in the ARS consultation service only limits to voice, such as carrying out the fortune-telling that essential information exchanges with consultation information or multiple business such as read a dream can realize by ARS by voice.Simultaneously, because the ARS consultation service provides in real time, if therefore consultant comes off duty or when a plurality of counsel requests is arranged simultaneously, the business of can not providing advice.Simultaneously, because the ARS consultation service needs expensive CTI (computer telephone integration) equipment, so the service provider is difficult to start the ARS consultation service.

Figure 2 shows that according to the present invention is based on the method that VoIP is used for the call reverse charging business.
With reference to Fig. 2, call reverse charging according to the present invention is by providing professional at calling terminal with as voip network between the called gateway of PSTN-VoIP connected node and the PSTN/ mobile network between called gateway and terminal called.Voip network comprises calling terminal, called gateways and called gateway, and comprises gatekeeper and call reverse charging acting server.The PSTN network comprises call reverse charging switch and universal exchange, and the mobile network comprises MSC (mobile switch center, mobile switching centre) and BSC (base station controller, base station controller).
The difference of the call reverse charging business that call reverse charging of the present invention is professional and traditional is that the called subscriber is that the expense that the paying link is paid is to be scheduled to according to the type and/or the position of terminal called.Because all in the present invention calling terminals send call request and carry out audio call on voip network, so the type of calling terminal is all identical.For example, if the type of calling terminal is a portable terminal and the type of terminal called is the plain old telephone that is connected with PSTN, comprise that then the call reverse charging expense of PSTN usage charges and mobile network's usage charges and access to netwoks expense is paid by the called subscriber.In another example, if calling terminal is positioned at abroad, comprise that then the call reverse charging expense of external local call expense and international call expense is paid by the called subscriber.But,, therefore can reduce the expense of call reverse charging owing to when the caller asks call reverse charging, use the extra charge of voip network can not be imposed to caller and called subscriber in the present invention.Below in conjunction with the variation of embodiment explanation according to the call reverse charging expense of the position of terminal called.Be positioned at the call reverse charging switch under the situation of Seoul (Seoul), if terminal called is positioned at Seoul, the called subscriber pays the expense of local call expense as call reverse charging, if but when the called subscriber was positioned at Gyeonggi (Kyung-gi) away from Seoul, the called subscriber must pay the expense of trunk call expense as call reverse charging.But if calling terminal is connected to the service provider's who is used for special-purpose telecommunications (special telecom) voip gateway, the calling link between calling terminal and gateway is by caller or called subscriber's payment.Policy according to the service provider can change the disburser that business provides expense.
In order to reduce expenses, calling terminal must have the VoIP access function and the call reverse charging switch must have VoIP call reverse charging processing capacity, the call reverse charging request of VoIP terminal can be distinguished to carry out different processing with the call reverse charging request of PSTN/ portable terminal.In the present invention, the calling terminal that can visit voip network comprises that (1) embeds the computer that gateway module is arranged in software or hardware; (2) embedding has the VoIP stand-alone phone of gateway module and the phone that (3) can be connected to called gateways by traditional telephone network (for example PSTN/ mobile network) in software or hardware.Describe with reference to the accompanying drawings and be used for the method and the system thereof of VoIP call reverse charging system according to the preferred embodiment of the invention.
Fig. 3 is the schematic diagram according to VoIP call reverse charging of the present invention system.With reference to Fig. 3, VoIP call reverse charging system comprises calling terminal, called gateways, called gateway, call reverse charging switch and terminal called.In addition, VoIP call reverse charging system also comprises gatekeeper's (not shown) and call reverse charging acting server 160.Some caller's terminals, called gateways and called gateway are connected to each other and are in the same place by the IP network (hereinafter referred to as " voip network ") of supporting the VoIP standard, and the call reverse charging switch is connected to each other and is in the same place by legacy network (hereinafter referred to as " PSTN network ") with terminal called.In addition, term " gateway " is meant the node that connects two heterogeneous networks in the present invention, and is used to describe and H.323 compatible preferred embodiment.Thereby, show and suggestion, to those skilled in the art, in another voip network of supporting with various criterion H.323, can replace gateway with equivalent entity.
Calling terminal comprises PC 100, VoIP stand-alone phone 110 and is connected to the phone 150 of voip gateway by the PSTN network.Called gateways can exist with different forms.Under the situation that adopts PC 100, the gateway module that is embedded in the software/hardware is included among the PC 100 or server that is connected with voip network, so the caller can be by PC 100 visit voip networks.Under the situation that adopts VoIP stand-alone phone 110, be embedded in the additional gateway that gateway module in the software/hardware can be included in the phone 110 or be connected with several VoIP stand-alone phone.Under the situation that adopts the phone 150 that is connected to voip gateway by the PSTN network, called gateways is connected to or is included in the switch.The call reverse charging request that is taken place by calling terminal 100,100,150 comprises the call reverse charging identifier and pays the telephone number of the terminal called of number as the other side that wherein said call reverse charging identifier is identified as call reverse charging by called gateways 130b, 130c or called gateway 130a.And the call reverse charging request also comprises: called subscriber's visit information, thus make called gateways 130b, 130c directly send the call reverse charging request to called gateway 130a.Comprise that when VoIP call reverse charging system the call reverse charging request also comprises the visit information of called gateway or gatekeeper/call reverse charging acting server under the situation of the gatekeeper that is used for RAS checking and gateway distribution (gateway assignment) or call reverse charging acting server.
Called gateway 130a is connected with called gateways 130b, 130c by voip network, and is electrically connected with the call reverse charging switch.The response of called gateway is from the call reverse charging request of caller's terminal 100,110 and 150, by and called gateways set up compatible link H.323 and realize audio call between two terminals.And called gateway sends VoIP call reverse charging notice, the processing thereby the call reverse charging switch can charge to the call reverse charging switch.
In a preferred embodiment of the invention, different with traditional VoIP system, use the PSTN link between call reverse charging switch and the terminal called to pay owing to using voip network not pay, therefore the visit information of called gateway can be disclosed.In traditional VoIP system, if undelegated tax-free call will frequently take place the visit information of open calling/called gateway.In order to prevent undelegated calling, traditional VoIP system management access information and user in the gatekeeper can't know.Thereby the user who has had the gateway that is used for other VoIP system can directly visit called gateway of the present invention by using disclosed visit information.In another embodiment, if VoIP system comprises the gatekeeper or is used to manage the call reverse charging acting server of a plurality of called gateways that are positioned at each district, so also can disclose the visit information of gatekeeper or call reverse charging acting server as mentioned above.
Call reverse charging switch 140 is electrically connected with called gateway 130a, and is connected with terminal called 120 by the PSTN network.140 responses of call reverse charging switch are from the call reverse charging request of called gateway 130a, be established to the PSTN link of called gateway 130a and terminal called 120 respectively, and connect each link, promptly, when the acknowledge(ment) signal that receives from the call reverse charging of terminal called 120, between calling terminal and terminal called, set up audio call.And, if between calling terminal and terminal called, set up audio call, just handle and carry out initialization chargeing.In a preferred embodiment of the invention, preferably, only the use of the PSTN link between call reverse charging switch and terminal called produces the expense as call reverse charging, and the expense of call reverse charging is unit costs and the product of being scheduled to according to the type of terminal called of total call time.But, policy according to the telecommunication service provider that manages call reverse charging switch 140 can adopt different charging methods, even in these cases, the target of charging only is the PSTN link between call reverse charging switch 140 and the terminal called 120.
Set up in the audio call between calling terminal and terminal called, 160 pairs of different types of networks of call reverse charging acting server (PSTN network, voip network) adopt different business of the present invention to handle (business process).Specifically, call reverse charging acting server 160 is carried out the network route that is used for the call reverse charging request is sent to call reverse charging network and voip network and is handled, is used to provide the caller to add up and call statistics/value-added service of CID (caller ID) provides and handles and be used to each network and call manager to produce the OA﹠amp of the statistics of chargeing; M (Operation, Administration, Maintance operation, management, maintenance) handles.In addition, if VoIP call reverse charging business only offers the user (subscribed member) of reservation, the call reverse charging acting server can have the subscribing user checking processing that is used for confirming to subscribe (subscription) validity and allows to have the right to use the collect call business.
Figure 4 shows that according to the flow chart that the present invention is based on the call reverse charging method of voip network.With reference to Fig. 4, in step 200, calling terminal sends and to comprise and be used to represent that type of call is the call reverse charging identifier and the call reverse charging number of call reverse charging.
In step 210, when receiving the call reverse charging request, from the call reverse charging request, extract the call reverse charging number and call out terminal called then.
In step 220, if the terminal called answering call, then definite response is the acceptance or the refusal of call reverse charging.According to the result who determines, be to accept if reply, then this method is proceeded step 230; Otherwise this method finishes in step 220.
In step 230,, between calling terminal and terminal called, set up voice call link so if the called subscriber sends the acknowledge(ment) signal of call reverse charging.In the voice call link after whole connection, the caller can exchange each other with the called subscriber.When connecting voice link, initialization is used to calculate the charging of total call time and handles.
In step 240, when the normal call ending request that receives from calling terminal or terminal called, discharge voice call link and finish the calculating of total time.
In step 250, the multiply each other expense that draws call reverse charging and the expense of this call reverse charging of total call time that calculates and unit costs paid by the called subscriber.
Figure 5 shows that signal flow graph according to VoIP call reverse charging of the present invention system.Specifically, Figure 5 shows that system signal flow chart with the gatekeeper who is used for the RAS checking.
With reference to Fig. 5, in step 300, calling terminal sends the call reverse charging request to called gateways.The call reverse charging request comprises call reverse charging identifier and call reverse charging number.If calling terminal is VoIP stand-alone phone or PC, can omit step 300.
In step 305, when receiving the call reverse charging request, called gateways is to sending call signal (call signaling) with the corresponding called gateway of call reverse charging identifier.Because this execution mode is carrying out with H.323 compatible VoIP system, so call signal is a protocol message H.225.And, in system, there is not the gatekeeper, so call signal directly sends to called gateway.When receiving call signal, called gateway is connected by voip network with called gateways.H.245 control signal message followed between gateway, and the agreement (not shown) exchanges.
In step 310, called gateway requests is to the PSTN link of call reverse charging switch.The collect call switch is established to the PSTN link of called gateway.
In step 315, the call reverse charging switch is included in call reverse charging number call terminal called in the call reverse charging request by use.When terminal called was replied, the call reverse charging switch was established to the PSTN link of terminal called, and in step 320, output informs that this is the verbal announcement of call reverse charging.
In step 325, after finishing verbal announcement, the call reverse charging switch is set up voice call link temporarily between calling terminal and terminal called, thereby makes the called subscriber can the call identifying person.Policy according to telecommunication service provider can be omitted step 325.
In step 330 to 340, after discharging voice call link, be used to ask to accept the verbal announcement of call reverse charging to terminal called output.When receiving with the corresponding dtmf signal of specific button, the call reverse charging switch is analyzed this signal and is judged whether the called subscriber accepts call reverse charging.According to judgement, if the called subscriber accepts call reverse charging, the call reverse charging switch connects voice call link and the initialization charging processing between calling terminal and the terminal called so.
Then, when the normal call ending request that receives from calling terminal or terminal called, discharge voice call link and calculate total call time, and produce the expense of call reverse charging.
Figure 6 shows that signal flow graph according to VoIP call reverse charging of the present invention system.Specifically, Figure 6 shows that the flow chart of the gatekeeper's signal that comprises that call reverse charging approval and metering data are confirmed.Under the situation that does not hinder spirit of the present invention, omit the description identical with Fig. 5.
With reference to Fig. 6, in step 400, when receiving the PSTN link of connection and the corresponding request of call reverse charging request, called gateways is established to the PSTN link of calling terminal.If calling terminal is VoIP stand-alone phone or PC, can omit step 400 so.
In step 405, if set up the PSTN link, so called gateways to call proxy server send the call reverse charging request and about the information of caller party terminal it is delivered to called gateway.In addition, if desired, called gateways can confirm that the calling party can use the validated user of call reverse charging business and carry out the processing of chargeing as the calling party by the request call acting server.
In step 410 and 415, when receiving call reverse charging request and caller party information, the call reverse charging acting server judges whether the calling party has the right to use the call reverse charging business and send judged result by called gateways to calling terminal.In more detail, the call reverse charging acting server is delivered to one of collect call network and voip network according to the call reverse charging number with the call reverse charging request, for each caller produces call statistics, and provides the supplementary service such as CID.And the call reverse charging acting server charges for each network generates and adds up and the administer calls processing.In addition, handle if each caller requires to charge, the call reverse charging acting server can be carried out for this reason and confirm to handle so.
In step 420, the call reverse charging acting server sends and the corresponding call signal message of collect call request to called gateway, thereby called gateways and called gateway are connected to each other.
Because step 425 is identical with step 310 to 340 to step 455, so omitted description to these steps.
Figure 7 shows that signal flow graph by call reverse charging acting server and gatekeeper.Specifically, Figure 7 shows that the signal flow graph of the VoIP system that comprises the gatekeeper who is used for RAS.Under the situation that does not hinder spirit of the present invention, omitted the description identical with Fig. 5 and Fig. 6.
Because step 500,505 with 515 with Fig. 6 in step 400 to arrive step 410 identical, omitted description to these steps.
In step 510, when receiving call reverse charging request and caller party information, the collect call acting server sends RAS message to the gatekeeper of all VoIP system entities of management.When receiving RAS message, the call reverse charging that gatekeeper registers called gateways and approval are asked.And the gatekeeper handles the call reverse charging request: the visit information of seeking the called gateway be suitable for handling the call reverse charging request.
In step 520, the gatekeeper sends registering result and the approval of call reverse charging and the visit information of called gateway of called gateways to the collect call acting server.When receiving the visit information of approval result of call reverse charging and called gateway, call reverse charging acting server approval calling party uses the call reverse charging business.
In step 525, the call reverse charging acting server sends result of approval to caller party terminal, and in step 530, send the call reverse charging request to called gateway, so called gateways is connected to each other with called gateway and is in the same place according to the visit information that receives from the gatekeeper.
