Description
Technical field
The present invention relates to communication technical field, be specifically related to a kind of mobility treating method and communications network system of idle mode terminals.
Background technology
In the communications network system, group node can be defined as the identical a plurality of nodes of movement law, and moving of group node can be called group and moves, these nodes present similar mobile route and mobile opportunity, and they almost enter another one network entity coverage from the coverage of a network entity simultaneously.Node in the group may be in enable mode, also may be in idle pulley.
Under idle pulley, terminal MS can move in a very big zone, and this zone is made up of a plurality of base station BSs, is called paging group PG.MS needn't carry out the position at the BS of roaming cell in the roam procedure in this zone upgrades, thereby helps saving interface-free resources and MS power consumption.Be in the MS of idle pulley, can receive the downlink broadcast service message every certain cycle, perhaps beep-page message is checked paging group information wherein.Only when paging group changes, just transmit, to carry out position updating process to BS.
Relay station RS provides service for MS, and a kind of application scenarios of RS is exactly mobile-relay station MRS, for example disposes MRS in train, for the MS of train inside provides service.MRS is along with a large amount of MS move together in this case, and assists them to move, and at this moment, MRS is a plurality of MS services, this MRS can be called a group, and MS wherein is called group node.Because the positional information of MS is mainly safeguarded by network side under the idle pulley, therefore, when moving, then there is the problem of management of idle mode terminals under the mobile simultaneously scene of MRS and subordinate's thereof MS in group.
It is current that management is provided with a cover mechanism for the terminal idle pulley.Mainly comprise: paging controller PC is responsible for idle pulley MS is managed, and comprises entering/exit from idle mode, and the position is upgraded, paging; Location register LR is as a distributed data base, and each example correspondence an anchor paging controller Anchor PC in the distributed data base, and Anchor PC has comprised all information of MS under the idle pulley.PC and LR generally are arranged on same entity, so general Anchor PC also can be expressed as AnchorPC/LR.Anchor PC is MS when entering idle pulley by logout flow path, is distributed by access service network gateway ASN-GW, and that distribute usually is the PC of current ASN inside.MS can carry out the position when crossing over paging group upgrades, the PC identifier of new ASN can be recorded to the LastReported PC field among the location register LR, and the PC of current new ASN (the Last Reported PC of MS) is to Anchor PC report self place BS and paging group.When receiving downlink data, Anchor PC to be transferred to MS, when promptly needing paging MS, Anchor PC sends paging announcement Paging_Announce message to the PC of current new ASN, PC by current new ASN carries out paging to the BS of MS place paging group, sends paging bulletin MOB PAG-ADV message by BS to MS again.But, this management for idle pulley is at present carried out at single terminal, do not relate to processing for group's mobile node, when the MS under a large amount of idle pulleys of MRS and its subordinate moves to another one paging group zone from a paging group zone, all subordinaties' of MRS the MS that is in idle pulley, detect paging group variation has taken place, so almost initiated position updating process at the same time, this can increase signaling consumption, cause a large amount of conflicts eating dishes without rice or wine to insert synchronizing process, processing for the network equipment brings enormous impact, even may cause network paralysis.
Prior art is at the problems referred to above, and idle schema management has proposed the scheme that paging group is upgraded in moving for the group, can avoid a large amount of MS almost to carry out the position simultaneously and upgrade the signaling storm that brings.In this scheme, distribute an independently paging group sign PG-ID to MRS, and this PG-ID can not change in the process that whole M RS moves.When MRS and affiliated MS thereof enter into the scope that a BS covers, in the handoff procedure or network re-entry process of MRS, use this PG-ID to upgrade the PG-ID tabulation of BS.BS issues when containing PG-ID message, adopts the PG-ID tabulation after the renewal contain this PG-ID.Like this, when the paging group zone of the actual process of MS changed, what MS felt was not that original PG-ID disappears, and just variation has taken place other PG-ID in the PG-ID tabulation, do not upgrade thereby can not initiate the position, avoided a large amount of MS almost to carry out the position simultaneously and upgraded the signaling storm that brings.
Seeing also Fig. 1, is method for processing idle mode mobility flow chart during the prior art group moves, and comprising:
Step 102, serving BS broadcasts send handoff request HO_Req message to target BS, carry out resource query and request switching to target BS;
Step 103, target BS are agreed the switching of MRS, send handoff response HO_Rsp message to serving BS broadcasts;
Step 104, serving BS broadcasts send BS handoff response MOB_BSHO-RSP message, inform MRS with switching the result who prepares;
Step 105, MRS initiate to switch to selected target BS, send to switch indication MOB_HO-IND message to serving BS broadcasts;
Step 106, serving BS broadcasts send switching authentic HO_Conf message to target BS, inform that MRS switches, and carry the PG-ID that distributes to MRS in HO_Conf message; Target BS begins to wait for that MRS inserts;
Step 107, target BS send to switch confirms HO_ACK message to serving BS broadcasts, confirms to switch;
Step 108, MRS disconnect with being connected of former serving BS broadcasts after, under target BS, network, transmission distance measurement request RNG-REQ message is to target BS;
Step 110, target BS send to switch to serving BS broadcasts finishes HO_Complete message, and the notice switching is finished.
In research and practice process to prior art, the inventor finds that there is following problem in prior art: when group nodes MS moves with MRS, because MS can not perceive the variation of PG-ID, also upgrade with regard to not carrying out the position because of crossing over paging group, but work as MS under idle pulley, network side is a latest position of judging MS according to the location update message of MS, and MS may not can when striding paging group carries out the position renewal now, thereby network side can't be known the latest position of MS under the idle pulley, causes can't paging arriving this MS in needs.

Embodiment
The embodiment of the invention provides a kind of method for processing idle mode mobility and communications network system, can make idle mode terminals not carry out under striding the paging group situation of movement guaranteeing when the position is upgraded that terminal can paged arriving.
The scheme of the embodiment of the invention mainly is that network side is when MRS networks or start group's locomotive function, distribute an anchor paging controller Anchor PC and specific paging group sign PG-ID to MRS, when MRS cross-domain when mobile, network side is initiated the position to the Anchor of MRS PC and is upgraded, by the latest position of the Anchor PC of MRS record MRS, perhaps further upgrade the positional information of MS on this basis according to the position of MRS; When paging MS, beep-page message can be sent to the current place PC of MRS (the Last Reported PC of MRS) MS is carried out paging, also can under the situation that the MS positional information is updated, beep-page message be sent to the current place PC of MS (the Last Reported PC of MS) MS is carried out paging.Like this, in the process that MRS moves, MS does not feel that variation had taken place the paging group at place when it entered idle pulley, thereby has avoided the MS of a large amount of idle pulleys to initiate the position renewal simultaneously and cause the signaling storm when MRS moves; Simultaneously,, do not initiate the position more under the news at MS so, can obtain the position of MS, thereby guarantee moment of needing arbitrarily by the position of following the tracks of MRS because MS and MRS move together, network side can paging to MS.
Seeing also Fig. 2, is embodiment of the invention method for processing idle mode mobility flow chart, comprising:
MRS is when networking or start group's locomotive function, inform that the BS self among the ASN possesses the MRS function, ASN-GW among the ASN is that MRS distributes an anchor paging controller Anchor PC, described Anchor PC distributes a distinctive paging group sign PG-ID to MRS, and the pairing relay station of this PG-ID of record identifies RS ID in location register LR.
Need to prove, the embodiment of the invention is that the anchor paging controller with the MRS that distributes is that MRS distributes a distinctive paging group sign PG-ID to illustrate, but being not limited to this, also can be that MRS distributes a distinctive paging group sign PG-ID by other network element devices of network side.
This step idiographic flow can be consulted flow process shown in Figure 3.Fig. 3 is in the embodiment of the invention method for processing idle mode mobility to comprise step by MRS allocation of parameters flow chart:
Step 301, MRS initial network entry or when starting group's locomotive function are mobile-relay station Mobile RS to the relay station type RS Type of BS report oneself, and it has group locomotive function to inform network;
The Anchor PC of step 304, MRS distributes a specific PG-ID to MRS, and the pairing RS ID of this PG-ID of record in LR returns to ASN-GW with PG-ID and the Anchor PC ID of self by going into net state change response IM_Entry_State_Change_Rsp message then;
Step 307, BS start group's locomotive function parameters needed (PG-ID, Anchor PC-ID) with MRS and store in the context of this MRS, and by relay station configuration description RS_CD message PG-ID are handed down to MRS.In addition, BS also can be handed down to MRS with Anchor PC-ID by RS-CD message.
The anchor paging controller of the position informing mobile-relay station that step 202, network side move mobile-relay station carries out record by the anchor paging controller of mobile-relay station;
The purpose of this step is in order to write down the change in location of mobile-relay station, so that network side can be grasped the latest position of this mobile-relay station all the time, specifically can be divided into three kinds of situations:
First kind of situation: when the anchor paging controller of the anchor paging controller of terminal and mobile-relay station is set together, the laggard line item of positional information that the mobile-relay station that only needs the anchor paging controller of mobile-relay station to receive the network side notice moves;
Second kind of situation: when the anchor paging controller of the anchor paging controller of terminal and mobile-relay station is set together, the positional information that the mobile-relay station of the anchor paging controller reception network side notice of mobile-relay station moves, the position that the record mobile-relay station moves, and further upgrade the location information of terminals that is in idle pulley in the described mobile-relay station;
The third situation: when the anchor paging controller of the anchor paging controller of terminal and mobile-relay station is not set together, the anchor paging controller of the location information notification mobile-relay station that network side moves mobile-relay station, after the anchor paging controller of mobile-relay station writes down, the further anchor paging controller of notice terminal upgrades described location information of terminals by the anchor paging controller of terminal.
Following elder generation is introduced the related procedure of first kind of situation.
When MRS cross-domain (comprise and stride BS or stride ASN-GW or the leap paging group) was mobile, network side was initiated the position to the Anchor of MRS PC and is upgraded.Owing to have only all terminals below the MRS all to enter idle pulley, do not have after the up-downgoing transfer of data, MRS just might enter idle pulley.Therefore under reality, MRS generally can not be in idle pulley.In the handoff procedure of MRS, the more PG-ID tabulation of fresh target ASN and service ASN, and target ASN is after MRS inserts, initiating the position to the Anchor of this MRS PC upgrades, write down the latest position (the Last Reported PC ID that comprises BS ID and MRS) at MRS place by the Anchor PC of MRS, can grasp the latest position of this MRS all the time to guarantee network.
The idiographic flow of first kind of situation can be consulted flow process shown in Figure 4.To be that MRS is cross-domain in the embodiment of the invention method for processing idle mode mobility initiate the flow chart that the position is upgraded to the Anchor of MRS PC when mobile to Fig. 4, comprises step:
Step 404, service ASN send BS handoff response MOB_BSHO-RSP message to MRS, comprise in this message and switch the result who prepares;
After target ASN receives HO_Conf message, upgrade the PG-ID tabulation, promptly add the PG-ID of MRS.Like this, when the paging group zone of the actual process of MS changed, what MS felt was not that original PG-ID disappears, and just variation has taken place other PG-ID in the PG-ID tabulation, does not upgrade thereby can not initiate the position.
Step 409, MRS disconnect with being connected of former service ASN after, under target ASN, network, transmission distance measurement request RNG-REQ message is to target ASN;
Step 410, target ASN initiate the position to the Anchor of MRS PC and upgrade (because the switching of having crossed over ASN), send the Anchor PC of position updating request LU_Req message to MRS, wherein carried the BS ID at the current place of MRS, and the PC ID of this target ASN;
The Anchor PC of step 411, MRS notes the latest position information of MRS in LR: the BS ID at current place, and this reports the PC ID (the Last ReportedPC ID of MRS) of the ASN of location updating message, home position renewal response LU_Rsp message;
Step 412, target ASN send ranging response RNG-RSP message to MRS;
Wherein, the PG-ID of MRS and Anchor PC id information can be delivered to objective network by the switching interacting message between service ASN and the target ASN, also can bring target ASN in the RNG-REQ message that target ASN networks by MRS.By the operation of this process, can guarantee that network is following at any time, can both know the latest position of MRS.
Then the related procedure to second kind of situation is introduced, the flow process of second kind of situation is to increase step on the process base of first kind of situation, be in the step 411, the anchor paging controller of mobile-relay station writes down the latest position information of mobile-relay station in the location register of mobile-relay station after, further upgrade the location information of terminals that is in idle pulley in the mobile-relay station, be specially: the anchor paging controller of described mobile-relay station writes down following information in the location register of the anchor paging controller of terminal: the paging controller sign at the Base Station Identification at the current place of described mobile-relay station of network side notice and the current place of terminal, thus guarantee that location information of terminals is exactly current latest position.
Related procedure to the third situation is introduced again, in the third situation, the anchor paging controller of terminal and the anchor paging controller of mobile-relay station are not set together, therefore, the anchor paging controller of the position informing mobile-relay station that network side moves mobile-relay station, after the anchor paging controller of mobile-relay station writes down, need further notify the anchor paging controller of all terminals to upgrade the location information of terminals that is in idle pulley, be specially: network side identifies the anchor paging controller that sends to all terminals with the Base Station Identification at the current place of mobile-relay station and the paging controller at the current place of terminal, the anchor paging controller of described all terminals receives the Base Station Identification at the current place of described mobile-relay station and the paging controller sign at the current place of terminal, carries out record in location register.
The anchor paging controller that foregoing is mentioned the anchor paging controller of terminal and mobile-relay station is set together, for this situation, specifically: as PG-ID and the Anchor PC of the MS that enters idle pulley, the Anchor PC of all MS under this MRS is left on the Anchor PC of MRS the PG-ID of MRS and Anchor PC.And the PG-ID of MRS and Anchor PC are comprised two kinds of situations as PG-ID and the Anchor PC of the MS that enters idle pulley, a kind of is to be in the situation that the MS among the MRS enters idle pulley, and a kind of is that the MS that has been in idle pulley enters the situation among the MRS.
The situation that enters idle pulley for the MS that is among the MRS, the process that its process and normal MS enter idle pulley is similar, difference is that ASN is different for the distribution of the Anchor PC of this MS, mainly comprise: the ASN-GW among the service ASN will distribute to the Anchor PC of the Anchor PC of MRS as this MS, rather than the PC of this ASN inside of acquiescence; The Anchor PC of MRS will distribute to the PG-ID of the PG-ID of MRS as this MS; The Anchor PC of MRS informs the Anchor PC ID of MS to the Anchor of MS DPF (data path functions)/FA (external agent) after MS enters idle pulley.Detailed process in the case sees also Fig. 5, is to be in the embodiment of the invention method for processing idle mode mobility to comprise MS allocation of parameters first pass figure:
Step 501, the BS of MS in service ASN send de-registration request DREG-REQ message, trigger, and to enter idle pulley, it is current attached to the information Paging Info above the MRS to have comprised MS among the described DREG-REQ;
Step 502, BS transmit into net state change request IM_Entry_State_Change_Req message to ASN-GW, and it is current attached to the information Paging Info above the MRS wherein to have comprised RS ID and MS;
The MS that step 503, ASN-GW find to enter idle pulley is the group's portable terminal below the MRS, so distribute the Anchor PC of the Anchor PC of MRS as this MS, rather than the PC of this ASN inside of distribution acquiescence is as the Anchor PC of this MS, and transmit into the Anchor PC of net state change request IM_Entry_State_Change_Req message, wherein comprise the FA ID of RS ID, Paging Info and this MS to this MRS;
The Anchor PC of step 504, MRS agrees that MS enters idle pulley, is back into net state change response IM_Entry_State_Change_Rsp message to ASN-GW, wherein comprises Anchor PC ID;
Step 505, ASN-GW return IM_Entry_State_Change_Rsp message to BS;
Step 506, BS send to MS and nullify order DREG-CMD message, and instruct MS enters idle pulley;
Step 507, BS are back into the net state change to ASN-GW and confirm IM_Entry_State_Change_Ack message;
The Anchor PC of step 509, MRS sends anchor paging control indication Anchor_PC_IND message to the Anchor of MS DPF/FA, wherein comprise Anchor PC ID, notify the present MS of Anchor DPF/FA of this MS to enter idle pulley, and Anchor PC is the Anchor PC of MRS;
The Anchor DPF/FA of step 510, MS returns anchor paging control to the Anchor of MRS PC and confirms Anchor_PC_Ack message.
Here need to prove that the MRS information among the ASN-GW is that MRS networks below this ASN-GW, obtain by this ASN-GW when perhaps switching to this ASN-GW.
Enter situation among the MRS for the MS that is in idle pulley, when the MS under the idle pulley enters MRS, can initiate the position upgrades, the process that its process and normal idle pulley MS position are upgraded is similar, difference is that ASN can trigger the repositioning process of the Anchor PC of this MS, mainly comprise: service ASN is reoriented to the Anchor PC of MRS with the Anchor PC of MS when the MS position is upgraded, the Anchor PC of described MRS will distribute to the PG-ID of the PG-ID of MRS as this MS; The AnchorPC of MRS informs that to the Anchor of MS DPF/FA the Anchor PC of MS has been reoriented on the Anchor PC of MRS after the MS completing place is upgraded.The detailed process of this situation sees also Fig. 6, is to be in the embodiment of the invention method for processing idle mode mobility to comprise MS allocation of parameters second flow chart:
Step 601, MS enter MRS, upgrade to current service ASN trigger position by distance measurement request RNG-REQ message, and the Anchor PC ID and the MS that have comprised MS in the described RNG-REQ message are current attached to the information Paging Info above the MRS;
The Anchor PC of step 603, MRS sets up correlation behavior as relay PC, transmits the former Anchor PC of this LU_Req message to MS, comprises the Anchor PCID of RS ID, Paging Info, MRS in the message;
The former Anchor PC of step 604, MS agrees position renewal and the Anchor PC reorientation of MS, and home position upgrades the Anchor PC of response LU_Rsp message to MRS, comprises the AnchorPC ID of MRS in the message;
The Anchor PC of step 605, MRS returns LU_Rsp message to the service ASN at this MS place;
Step 606, service ASN return ranging response RNG-RSP message to MS, wherein comprise the Anchor PC ID of MRS;
Step 607, service ASN upgrade to the Anchor of MRS PC home position and confirm LU_Cnf message, the expression position upgrades and the PC reorientation is finished, the Anchor PC of MRS creates the positional information record of this MS in LR, so far the Anchor PC of the Anchor PC of MS and MRS has navigated to together;
The Anchor PC of step 608, MRS sends anchor paging controller reorientation indication PC_Relocation_IND message to the Anchor of MS DPF/FA, the Anchor PC ID that wherein comprises MRS, notify the Anchor DPF/FA of this MS, the up-to-date Anchor PC of MS is the Anchor PC of MRS;
The Anchor DPF/FA of step 609, MS returns anchor paging controller reorientation indication PC_Relocation_Ack message to the Anchor of MRS PC;
The Anchor PC of step 610, MRS returns LU_Cnf message to the former Anchor PC of MS, and the expression position upgrades and the PC reorientation is finished, the relevant information of the former Anchor PC deletion MS of MS.
By MS is entered idle pulley below MRS processing, and to the processing that the MS under the idle pulley enters MRS, the Anchor PC that can make idle pulley MS all below this MRS is in the same place with the Anchor PC of MRS all the time.
Three kinds of situations that comprised when having mentioned the change in location that writes down mobile-relay station in the above-mentioned steps 202, for these three kinds of different situations, different to the flow process that the described terminal that is in idle pulley is carried out paging.
Paging flow process for first kind of situation: because only upgraded the positional information of mobile-relay station, location information of terminals is not upgraded, so when call terminal, the anchor paging controller of terminal finds that terminal is in (coverage that is in mobile-relay station is interior) in the mobile-relay station, mobile-relay station positional information according to the anchor paging controller of mobile-relay station record, beep-page message is sent in the paging controller at the current place of mobile-relay station of writing down in the described mobile-relay station positional information, described terminal is carried out paging by the paging controller at the current place of described mobile-relay station.
Below specifically introduce the paging flow process under this situation.
Introducing after group moves, MS has crossed over after the outside paging group geographically, can not initiate the position and upgrade, so the Anchor PC of this MS can't directly know the current location of this MS.But owing to after adding group, MS and MRS are in the same place all the time, so the current location of MS can be determined indirectly by the current location of MRS.Processing by the front, guaranteed that network (the Anchor PC of MRS) grasps the latest position of MRS all the time, and the Anchor PC of MS is in the same place with the Anchor PC of MRS all the time, so in this MS of paging, when MS/MRS Anchor PC finds the BSID at paged MS place is that MRS is when promptly finding that MS is in MRS, because the Last Reported PC of MS can not reflect the latest position of MS, so beep-page message is sent to the Last Reported PC of MRS, the PC of this just current MS place ASN carries out paging by described PC to MS.
This situation correlation step idiographic flow can be consulted flow process shown in Figure 7.Fig. 7 is the flow chart that is in the MS of idle pulley in the embodiment of the invention method for processing idle mode mobility among the paging MRS, comprises step:
The Anchor DPF/FA of step 701, MS receives downlink data, finds that MS is in idle condition, sends the current Anchor PC of initial paging request Initiate_Paging_Req message to MS;
The Anchor PC of step 702, MS returns the Anchor DPF/FA that initial page response Initiate_Paging_Rsp message is given MS;
When the Anchor PC of step 703, MS finds that the BSID at paged MS place is MRS, because the Last Reported PC of MS can not reflect the latest position of MS, the Last Reported PC during so write down definite position that beep-page message need be sent to the Anchor PC of MRS, the PC of this just current MRS place ASN;
The Anchor PC of step 704, MS announces Paging_Announce message with paging and sends to the current ASN of MRS;
The Anchor PC of MS is according to the PC ID of the current ASN of the MRS of the Anchor PC of MRS storage, and paging is announced among the PC (the LastReported PC of MRS) that Paging_Announce message sends to the current ASN of MRS.
The PC of the current ASN of MRS carries out paging to the BS of MS place paging group, sends paging bulletin MOB_PAG-ADV message to MS by BS.
Step 706, MS respond paging, exit from idle mode, and network again.
Paging flow process for second kind of situation is: because the anchor paging controller of mobile-relay station has further upgraded the location information of terminals that is in idle pulley in the described mobile-relay station, so when call terminal, the anchor paging controller of terminal finds that terminal is in the mobile-relay station, can be directly according to the terminal positional information after upgrading, beep-page message is sent in the paging controller at the current place of terminal of writing down in the described terminal positional information, described terminal is carried out paging by the paging controller at the current place of described terminal.
Paging flow process for the third situation: because the anchor paging controller of all terminals has upgraded the location information of terminals that is in idle pulley in the described mobile-relay station, so when call terminal, the anchor paging controller of terminal finds that terminal is in the mobile-relay station, according to the terminal positional information after upgrading, beep-page message is sent in the paging controller at the current place of terminal of writing down in the described terminal positional information, described terminal is carried out paging by the paging controller at the current place of described terminal.
