The present invention includes the steps of receiving a message requesting a transition to the idle mode from a mobile subscriber station, transmitting paging information for the entire paging groups of the base station to the mobile subscriber station, and transmitting a paging message to the mobile subscriber station according to the paging information of each of the paging groups to which the base station belongs.
Description
Technical field
The present invention relates to BWA, particularly, the method for control idle pulley in BWA.Though the present invention is applicable to range of application widely, the specific method of controlling idle pulley by the paging information sending method of improvement in BWA in the base station or in the mobile subscriber station effectively that is applicable to.
Background technology
Usually, BWA is supported idle pulley, to reduce the power consumption of mobile subscriber station (being abbreviated as MSS hereinafter).
Paging domain is defined as the Zone Full of being responsible for by a plurality of base stations in a paging group.Each base station that comprises in identical paging zone has identical paging cycle Paging_Cycle and identical paging offset amount Paging_Offset.
MSS can change to idle pulley to base station requests.Then, its paging group ID (Paging_Group ID), corresponding paging cycle and corresponding paging compensation are transmitted in the base station.Therefore, this corresponding M SS enters idle pulley.
When idle pulley, MSS can determine whether keeping or stopping this idle pulley from the base station with the paging of forms of broadcasting transmission by each paging cycle.
If occur in the business that idle pulley MSS must send, then MSS can stop this idle pulley at any time.Must be if take place to the business that sends at idle pulley MSS, then the base station can make MSS stop idle pulley by paging.And if move to another paging domain or lose its synchronous MSS in idle pulley paging receiving at the fixed time, then MSS stops idle pulley.
When idle pulley, in belonging to the move between base stations of identical paging domain, MSS does not need to carry out handoff procedure.Therefore, MSS does not need to send to the base station up-link information of handoff procedure, thereby reduces corresponding power consumption.That is, when the information that will not send/receive, the paging of the normal receiving cycle of MSS in idle pulley is to guarantee its moving freely and do not carry out handoff procedure in identical paging domain.
Describe MSS idle pulley conversion process below in detail according to prior art.
At first, send idle-mode request message in order to enter idle pulley MSS to serving BS.Then, serving BS sends paging group ID, paging cycle and paging offset amount by the idle pulley response message to MSS, and discharge link information to MSS, to the MSS assigned radio resource etc.
Table 1 illustrates from the base station to the example of request to the idle pulley response message of the MSS of idle pulley transformation transmission, the wherein conventional cancel register instruction message (DREG-CMD) of use.
[table 1]
| The syntax | Size | Note |
| DREG-CMD_Message_Format(){ | ||
| Management?Messaage?Type＝29 | 8 |
| Action?code | 8 | |
| TLV?encoded?parameters | Variable | |
| } |
Table 2 and table 3 illustrate the action code definition and the TLV coded format of cancel register instruction message respectively.
[table 2]
[table 3]
Ratify corresponding 0x05 if the action code of cancel register instruction is set at idle pulley, then the paging information shown in the table 3 is included in the cancel register instruction message that will send to MSS.
The MAC Address that other base station notices of the paging group of base station under corresponding base station enter the MSS of idle pulley.Therefore, corresponding base station makes that latter base station can enough identical paging cycle and the corresponding MSS of identical paging offset amount (offset) paging.
By the broadband form beep-page message that sends from the base station according to paging cycle, whether the MSS decision that allows to enter idle pulley by idle pulley response message base station exists will be to the downlink traffic of this MSS transmission itself, whether find range, or do not keep keeping idle pulley.
In case confirm to exist downlink traffic by beep-page message, MSS stops idle pulley and again to network registry, with receiving downlink data.If MSS finds range by page message request, MSS finds range and makes the base station can upgrade the position of MSS and effectively idle pulley MSS tabulation.In the time can not receiving the operation requests of regulation by this beep-page message, MSS keeps keeping this idle pulley.
If MSS leaves another base station that enters different paging groups, if or because the generation MSS of up link or downlink traffic stops this idle pulley, preceding base station under the MSS makes it possible to all the other base stations of so preceding paging group of fact notice from this idle-mode list deletion corresponding M SS.
Table 4 illustrates the example of data format of the beep-page message of the broadcasting format that receives from each base station of a paging group with consistent cycle according to the MSS of prior art in idle pulley.
[table 4]
Beep-page message comprises that indication sends the paging group ID under the logic of base station, and MSS is by MSS MAC Address hash sign, and beep-page message comprises at least one or a plurality of MAC Address.And beep-page message sends action code each MSS to corresponding M SS MAC Address hash sign.The next one action of action code indication MSS in idle pulley.
But, have following problem to the art methods of the MSS assigned paging information in idle pulley.
At first, the MSS that enters idle pulley in the borderline base station between paging group may need sizable power consumption, and this describes in detail below.
Be between paging group that borderline base station can have at least two paging groups so that realize the flexible net design, thereby have at least two paging cycle and paging offset amount.That is, be in that borderline base station can belong at least two paging groups between the paging group.
In the situation that receives idle mode request from MSS, base station the exhaling among the group ID under the base station that belongs to described at least two paging groups distributed paging group ID at random, corresponding paging cycle and corresponding paging offset amount are so that send to MSS by the idle pulley response message.But on the border that may exist in by the MSS that enters this idle pulley in borderline base station between the paging group between the paging group, therefore this MSS leaves from the paging group of distributing in the short time and enters different paging groups probably.
If have the base station that moves to the paging group that belongs to different to the idle pulley MSS of the specific paging group of its distribution, then paging cycle changes.Therefore, corresponding MSS can not receive the beep-page message of the paging group transmission that in the past distributes.And corresponding MSS should stop idle pulley, and enters normal manipulation mode.
That is, stop this idle pulley fast so that enter normal manipulation mode by being in the MSS that borderline base station between paging group enters idle pulley most probably.And MSS needs to send/and receiving uplink/downlinlc message is so that enter idle pulley by the base station that belongs to new paging group, thus increase its power consumption.
The second, because as long as MSS keeps this idle pulley, the base station just can not change the initial paging cycle and the side-play amount of original allocation when MSS enters idle pulley, the paging load of therefore regulating the base station is difficult.
The 3rd, the situation in the base station with at least two paging group ID to MSS assigned paging information is for which paging group information distribution should not being had concrete reference to MSS.That is,,, and do not consider the paging load of paging group then by selecting paging group assigned paging information randomly if distributed a paging information of described at least two paging groups.

See Fig. 1, first base station BS 1 of mobile subscriber station MSS under this mobile subscriber station MSS sends idle mode request (DREG-REG) message, to enter idle pulley (S11).At this moment, first base station BS 1 is the base station that belongs to first paging group and second paging group.
First base station BS 1 that has received idle-mode request message is by responding the paging group ID of (DREG-CMD) message under mobile subscriber station MSS transmission comprises first base station BS 1 through idle pulley, the paging information of paging cycle and paging offset amount allows mobile subscriber station MSS to enter idle pulley.In doing like this, belong to first first base station BS 1 that belongs to second paging group again and send the first paging group information and the second paging group information (S12) to mobile subscriber station MSS.
The paging group of first base station BS 1 under first base station BS 1, that is, other base station BSs 2 of first and second paging groups and BS3 send key (backbone) information, and MSS has entered idle pulley (S13) with the notice mobile subscriber station.Each base station BS 2, the BS3 that have received this backbone's information add this mobile subscriber station MSS to idle pulley MSS tabulation.When mobile subscriber station MSS sent beep-page message, according to the paging cycle of the corresponding paging group under base station BS 2 or the BS3, corresponding base station B2 or B3 sent beep-page message at needs.
Entered the mobile subscriber station MSS receiving downlink business not in the idle mould, but carried out the operation that only is used for receiving the beep-page message that sends from first base station BS 1 according to corresponding paging cycle.Therefore, the mobile subscriber station MSS that has entered idle pulley can reduce its power consumption.In belonging to situation about moving between the base station of identical paging group, mobile subscriber station MSS does not carry out switching separately, to reduce its power consumption.
Because first base station BS 1 had both belonged to first and had also belonged to second paging group, so mobile subscriber station MSS receives the beep-page message that sends from first base station BS 1, with the paging cycle (S14) of corresponding first and second paging groups.
In case move to second base station BS 2 that only belongs to first paging group from first base station BS 1, mobile subscriber station MSS keeps this idle pulley and only receives the beep-page message that is used for first paging group (S15) that sends from second base station BS 2.By confirming only to receive the beep-page message that is used for first paging group and by confirming that the beep-page message that is used for second paging group is not received, mobile subscriber station MSS decision, it has moved to the territory of first paging group, stops to receive the operation of the beep-page message of second paging group then.That is to say that mobile subscriber station MSS is not during the paging cycle of second paging group but in the paging cycle manipulate of first paging group.
Though mobile subscriber station MSS has moved to second base station BS, 2, the first base station BSs 1 still send first and second paging groups according to corresponding paging cycle beep-page message.Do like this,, also do not send uplink service separately to first base station BS 1 although mobile subscriber station MSS does not receive the beep-page message of second paging group.
If produce the downlink traffic (S16) of mobile subscriber station MSS from first base station BS 1, then other base stations of first paging group of first base station BS 1 under first base station and other base stations of second paging group send key message, and it comprises and has produced the downlink traffic that is used for this mobile subscriber station MSS.
After having discerned the generation of downlink traffic, each base station of first and second paging groups stops the idle pulley of this mobile subscriber station MSS, and sends the beep-page message (S18) that the instruction network reenters to mobile subscriber station MSS according to the corresponding cycle.At this moment, mobile subscriber station MSS confirms the instruction by this base station of the action code that comprises in beep-page message.
After having received the beep-page message of instruction idle pulley termination from second base station BS 2, second base station BS 2 of mobile subscriber station MSS under this mobile subscriber station MSS is current sends distance measurement request message, reenters process (S19) to stop idle pulley and to start network.
Second base station BS 2 that has received distance measurement request message sends key message to first base station BS 1, and with the current directorial area that belongs to it of notice mobile subscriber station MSS, and the down link data (S20) that produces from first base station BS 1 is transmitted in request.
First base station BS 1 sends key message to the base station of first and second paging groups, has stopped idle pulley (S21) and has sent the down link data (S22) that will pass to mobile subscriber station MSS to second base station BS 2 with notice mobile subscriber station MSS.From first base station BS 1 received should backbone's message each base station this mobile subscriber station of deletion MSS from idle pulley MSS tabulation.
In paging information distribution method according to the present invention, if mobile subscriber station is to the base station requests idle pulley that belongs at least two paging groups, the paging information of the whole paging groups under this base station of base station assigns then, the idle pulley MSS that this mobile subscriber station is added to it is tabulated in each base station of these paging groups, so that management.Therefore, move at mobile subscriber station under the situation in zone of its paging information of each paging group know to(for) this mobile subscriber station, this mobile subscriber station can be kept its idle pulley, and also can reduce its power consumption.
Fig. 2 is the idle pulley control method flow chart of another preferred embodiment according to the present invention, and the base station that wherein belongs at least two paging groups is with at random preferentially to the mobile subscriber station assigned paging information in the sub-district.
See Fig. 2, the base station BS 1 of mobile subscriber station MSS under this mobile subscriber station MSS sends idle-mode request message, to enter idle pulley (S31).And base station BS 1 had both belonged to first paging group and had also belonged to second paging group.
Whether base station BS 1 decision that receives idle-mode request message which paging information of the paging group under mobile subscriber station MSS sends base station BS 1.Can determine this paging group in every way.Preferably, as a reference, determine this paging group by the paging load that is taken between the paging group under the base station BS 1.Promptly, base station BS 1 is compared to each other the paging load of the paging group under the base station BS 1, then, by sending paging ID, paging cycle and the paging offset amount that comprises paging group to mobile subscriber station MSS, allow mobile subscriber station MSS to enter idle pulley (S32) with less paging load through idle pulley response message (DREG-CMD).
The data volume of the beep-page message that can send according to the mobile subscriber station of the base station that is subordinated to each paging group in idle pulley limits paging load.And rising at the number of the mobile subscriber station of idle pulley, paging load increases when higher.
The paging load of supposing first paging group is littler than second paging group, receive the base station BS 1 of idle-mode request message with the paging load of first paging group and the comparison of second paging group from mobile subscriber station MSS, then, send the paging information of first paging group with less paging load to mobile subscriber station MSS.
The mobile subscriber station MSS that receives the paging information of this first paging group receives the paging information (S33) that sends from base station BS 1 according to the paging cycle of first paging group.
Therefore, in the paging group of the base station that is subordinated at least two paging groups under the mobile subscriber station MSS that enters idle pulley is sent in this base station, have in the method for paging information of paging group of less paging load, the paging information that has the paging group of minimum paging load in paging group is sent out, or sends the paging information of at least two paging groups with less paging load with mode of priority.
