Description

In wireless access system, support the idle pulley of mobile radio station

Technical field

The present invention relates to wireless access system, especially, relate to the idle pulley of mobile radio station in wireless access system.

Background technology

BWA typically supports idle pulley the power consumption of mobile subscriber station (MSS) is reduced to minimum.During idle pulley, when moving between the base station in the identical paging zone, MSS does not carry out handoff procedure.Therefore, MSS does not need to transmit the up-link information that is used for handoff procedure, and this has reduced corresponding power consumption.

Paging zone is defined as the zone by a plurality of base stations control that are known as paging group.Each base station in the paging group has identical paging cycle (Paging_Cycle) and identical paging offset (Paging_Offset).

MSS can ask the base station to switch to idle pulley.This base station provides the beep-page message that comprises its paging group ID, corresponding paging cycle and corresponding paging offset then.Corresponding M SS thereby can be switched to idle pulley.During idle pulley, MSS can determine whether to continue or stop idle pulley based on the beep-page message that is provided by the base station on each paging cycle.

If service needed is transmitted by MSS when idle pulley, MSS can stop idle pulley.For example, MSS may be able to stop idle pulley by BS.In addition,, lose when idle pulley perhaps that it is synchronous if MSS moves to another paging zone, and can not paging receiving on the predetermined time, MSS can stop this idle pulley.

When MSS was in idle pulley, MSS receiving cycle paging normally need not to carry out handoff procedure and freely moves to guarantee it in identical paging zone.

In the process of configuration paging zone, key message (paging group action) transmits between the base station by wired.The paging group of a demonstration is moved key message shown in the table 1.

Paging group is moved key message and is exchanged between the base station.Based on the content of action field (action), paging group is moved key message and can be used to four purposes.Receive base station (target BS) and can be assigned with (appointment) to a specific paging group (action=0).Alternatively, target BS can be removed (action=1) from specific paging group.Alternatively, the paging group that belongs to about target BS can query aim BS (action=2).Alternatively, target BS can be learned the paging group (action=3) that sends base station (sender BS) and belong to.

Because a base station can belong to one or more radio calls district, this paging group is moved key message and can be comprised the information relevant with many paging groups.This base station can be moved key message via paging group and learn paging cycle and the skew of using in each paging zone.In addition, the base station can be moved key message via paging group and dynamically be distributed to paging group.

When MSS is converted to idle pulley, use DREG_REQ message (previous MAC message one).The form of DREG_REQ message is shown in the table 2.

Embodiment

To at length be introduced the preferred embodiments of the present invention now, its example illustrates in the accompanying drawings.As possible, run through the identical reference number of this accompanying drawing and will be used to represent identical or similar part.

The present invention can use under the background of IEEE 802 BWA standards.Alternatively, the present invention can use under the background of the wireless access system of any kind.

With reference to figure 1, paging group comprises at least one base station (BS).Each BS that belongs to identical paging group can transmit and/or receive the information of idle pulley needs in the mobile radio station (MS) via key message.Mobile radio station also is called mobile subscriber station (MSS).Alternatively, the required information of idle pulley can transmit and/or receive belonging between the BS of different paging group via key message among the MS.

With reference to figure 2, enter idle pulley in order to allow MSS, preferably can use login request message, arrive the switching (S21) of idle pulley such as for example DREG_REQ message to base station requests as media access controller (MAC) message.The form of the demonstration of DREG_REQ message is shown in the table 2.

MSS preferably can be by for example DREG_REQ message go the register requirement sign indicating number to be set to 0 * 01 to enter idle pulley to base station requests MSS.MSS can send DREG_REQ message to base station then.

The base station (reception base station) that receives DREG_REQ message preferably can respond the request (S22) of MSS via command messages such as for example DREG_CMD message.The form of the demonstration of DREG_CMD message is shown in the table 3.

This receives the base station and preferably can allow MSS to enter idle pulley via action code (for example, action code=0 * 05).Alternatively, this receives the base station and preferably can ask to enter idle pulley after the time duration of appointment via another action code (for example, action code=0 * 06) permission MSS.Alternatively, this reception base station can not allow MSS request before receiving base station transmission DREG_CMD message to enter idle pulley via another action code (for example, action code=0 * 07).

The details of the demonstration of the action code relevant with DREG_CMD message is shown in the table 4.

In one embodiment, the information relevant with the MSS that enters idle pulley preferably can be shared in the base station that belongs to identical paging zone.Use this information, the base station preferably can notify MSS MSS in each paging cycle need carry out what process.In order among BS, to share information, can use key message, key message is announced in paging as shown in table 5 such as example.All base stations (S23) that key message preferably can be transmitted to the paging zone that belongs to identical are announced in this paging.

In another embodiment, action code can be added to paging and announce key message, with the necessary operation that is used to instruct MSS will carry out when being in idle pulley.Therefore, in the example as table 7 below, compare NUM MSS with in the table 5 in the above those ", " MSS MAC Address ", " paging cycle (PAGING CYCLE) " and " paging offset (PAGINGOFFSET) " and paging other the field of announcing key message can be changed.Demonstration have increase be used to instruct the paging of action code of MSS to announce shown in the key message table 7 below.

In yet another embodiment, " PAGING_CYCLE (16) " and " PAGING_OFFSET (8) " field can be announced the key message from paging and delete, shown in top table 7, have identical paging cycle and paging offset because belong to each of base station of identical paging zone.Therefore, replace paging cycle and paging offset field, action code (for example, 3 bit action codes) can be increased to paging and announce key message, to be increased to paging list via action code (for example, action code=0) the expression MAC Address relevant with specific MSS.Alternatively, this action code can be deleted from paging list via the MAC Address of the specific MSS of another action code (for example, action code=1) expression.Alternatively, this action code can be represented to have carried out range finding (for example, action code=2) for updating location information.Alternatively, this action code can be illustrated in and stop having carried out network re-registration process (for example, action code=3) after the idle pulley.

Via paging send to from each base station MSS idle pulley such as the beep-page message form of MOB_PAG_ADV message shown in the table 6.This beep-page message preferably can be sent to MSS with broadcasting format.

MSS can paging receiving message, and the usage operation sign indicating number (for example, action code=00) determines whether (judgement) continues to keep idle pulley, whether the execution range finding is (for example to set up updating location information, action code=01), and/or whether stop idle pulley with receiving downlink business (for example, action code=10).

Serving BS preferably can allow specific MSS to enter idle pulley, and the action code that key message is announced in paging is set to 0, for example, then paging is announced key message and is sent to all base stations (S23) in the paging zone of serving BS.Key message can be announced by paging receiving in each base station in paging zone, and can store the MAC Address of corresponding M SS in paging list.Then, MAC Address (S24) can be transmitted via beep-page message MOB-PAG_ADV in this base station in each paging cycle.

MSS can paging receiving message, and preferably can determine to keep idle pulley.When doing like this, can be included in by the MAC Address with MSS and save radio resource in the beep-page message, this MSS needs specific action, such as re-registering network, perhaps is used for the range finding of updating location information.In order to comprise MAC Address, for example, in table 6 beep-page message MOB-PAG_ADV " MSS MAC Address hash " and " action code " field preferably can be changed with matching in table 8.

[table 8]

For(j＝0；j＜Num_MACs；j++){	?	?	MSS MAC Address hash	24	?
Action code	2	00=enters network 01=and carries out range finding to set up position and acknowledge message 10-11=reservation	MSS MAC Address hash	24	?

If MSS is because downlink traffic occurring is forced to stop idle pulley, each base station may not know that corresponding M SS belongs to the territory in the paging zone of each base station.The action code that paging therefore can be announced key message in each base station for example is set to 3, then paging is announced key message and is sent in identical paging zone to other base station.

Key message can be announced by paging receiving in other base stations in the paging zone of each base station, and the action code of beep-page message for example is set to 00.Other base station can send beep-page message to all MSS in paging zone then, stops idle pulley to allow corresponding M SS, and carries out the process that is used to re-register network.

After MSS normally stopped its idle pulley, the action code that paging can be announced key message in each base station for example was set to 1, and paging can be announced key message then and send other base station in paging zone to.Therefore, preferably can stop paging for corresponding M SS.

Fig. 3 illustrates according to the embodiment of the invention, is used to stop the schematic diagram of idle pulley process when the down link business will be transmitted to mobile radio station.

With reference to figure 3, because the territory that the MSS among the idle pulley belongs to may not known to be in the base station, downlink traffic preferably can unconditionally be sent to the base station (first base station or origin base station) that the MSS initial request switches to idle pulley.

Allowed to enter the MSS receiving downlink business of idle pulley by first base station after, first base station for example can the action code relevant with all base stations in the paging zone of first base station be set to 11.First base station can be transmitted paging then and be announced key message (S31).

Key message can be announced by paging receiving in each base station in the paging zone of first base station, and the action code of beep-page message MOB_PAG_ADV for example is set to 10.This base station can send beep-page message in paging zone all MSS (S32) with broadcasting format then.

Corresponding M SS can paging receiving message, and stop this idle pulley.This MSS can also ask to be responsible for second base station (current base station) of the affiliated paging zone of MSS, to re-register network (S33).Second base station preferably can be known the base station IDs of first base station via the paging notice message.

Second base station can receive the request of re-registering, and the action mark of the key message of MSS_Info_Request for example is set to 1.The key message of MSS_Info_Request preferably can transmit between the base station by wired.Second base station can send the key message of MSS_Info_Request to first base station then, has left paging zone (S34) to notify the first base station MSS.The form of the demonstration of the key message of MSS_Info_Request is shown in the table 9.

Except when MSS is forced to stop outside its idle pulley owing to downlink traffic, if the idle pulley of MSS need be terminated, MSS preferably can finish idle pulley via paging request MSS earlier than first base station carry out the idle pulley termination procedure.

After finishing the idle pulley that stops MSS, when the base station receives when re-registering the request of network from MSS, the action code that BS can announce key message for example is set to 1.Paging can be announced all base stations that key message sends the paging zone that belongs to relevant base station to then in the base station, makes corresponding M SS to delete from paging list separately.

With reference to figure 4, by supporting information necessary to be sent to the base station and/or receive this information necessary from the base station that paging controller is carried out the idle pulley control to the MSS in the base station of one or more paging groups for idle pulley.That is to say, can between the base station, be implemented as transmission and/or the reception that idle pulley provides information necessary via paging controller.This paging controller can be provided in the specific base stations, and perhaps can separate with the base station provides.

Fig. 5 illustrates the schematic diagram that is used to use the base station process of paging controller management in paging group according to the embodiment of the invention.

With reference to figure 5, this paging controller can use key message control to belong to the base station of each paging group.For example, use the action code of the key message of paging group action request, paging controller can (for example be given paging group with base station assigns, action code=0000), from specific paging group, deletes base station (for example, action code=0001), the paging information of request relevant base station (for example, action code=0010), the paging information (for example, action code=0011) of perhaps notifying another base station (S51).The paging group action request message of a demonstration is shown in the table 11.

[table 11]

The base station of paging receiving group action request message preferably can use the action code of paging group action response message to transmit the idle pulley information necessary.This paging group action response message can send paging controller (S52) to by the base station of paging receiving group action request message.For example, the response to paging group action request message can be transmitted in this base station, deletes BS (for example, action code=0000) to paging group or from paging group so that BS is increased.This paging group action response message can also be transmitted, so that its paging information (for example, action code=0001) is provided, perhaps from another base station inquiry paging information (for example, action code=0010).The paging group action response message of a demonstration is shown in the table 12.
