Embodiment
The present invention does not limit to and is applied to alleged WiMAX grid at present, more can be applicable to other network systems of being developed based on the WiMAX network architecture, as long as it satisfies this network architecture.But clearly demonstrating creation point of the present invention for more convenient, below is the example explanation with the WiMAX network.
The reference WiMAX network architecture shown in Figure 1:
In the WiMAX network architecture, ASN (access service network) is the network function set that the wireless access service is provided for terminal, and ASN has comprised BS (base station) and ASN GW (access service network gateway) network element.Wherein, BS mainly provides following function: the L2 (second layer) of base station and portable terminal is connected; RRM; Measure and power control; The compression of the data of eating dishes without rice or wine and encryption etc.ASN GW mainly provides following function: for MSS authentication function provides agent functionality, and AnchorAuthenticator (anchor authentication person) function; Support the network of NSP (Internet Service Provider) to find and selection; For MSS provides L3 (the 3rd layer) relay function (as IP address assignment) of information; RRM; In addition, can also comprise: ASN switches; Portable terminal paging and location management are as paging controller functional entity PC; Tunnel management between ASN and the CSN is equivalent to the FA (external agent) in the mobile IP technology, and Anchor PMIP Client (anchor proxy mobile IP customer terminal) functional entity; The vision location registration, Anchor SFA (anchor management service flow entity).
Each ASN-GW possesses multiple functional entity, as Data Path Function (datapath function), SFA (management service flow entity), Authenticator (authentication person), FA (external agent), PC (PagingController, paging controller), LR functions such as (location registers).But because terminal moves at network side, really this terminal is worked in certain particular moment, be that the anchor functional entity that we say may be arranged in different ASN-GW, so behind terminal access idle mode, the anchor paging controller that acts on this terminal may be at an ASN-GW, and its FA and authenticator, SFA may lay respectively among the different ASN-GW.That is to say that each functional entity may be arranged in different physical entities.
CSN provides IP Connection Service for terminal, and the IP address assignment of following function: MSS mainly is provided; Internet inserts; AAA agency or service; Authorization control based on the user; ASN is equivalent to the HA (home agent) in the mobile IP technology to the tunnel of CSN; WiMAX user's charging and the clearing between the operator; Tunnel under the roaming condition between the CSN; Switching between the ASN; Various WiMAX services are as location-based business, multi-medium multi-packet broadcasting and broadcasting service, IP Multimedia System business;
MSS is a mobile subscriber equipment, and the user uses this devices accessing WiMAX network.
Based on this network architecture, the present invention consults idle pulley by terminal and network side and keeps information when terminal access idle mode, and the idle pulley after will consulting then keeps information and is kept at respectively on terminal and the anchor paging controller thereof.Based on these reservation information, when terminal needs network re-entry, obtain these reservation information from its anchor paging controller, and carry out the position according to these information guide terminals and upgrade, or guiding terminal networks again by the Current Serving BTS of this terminal.
In order to make those skilled in the art person understand the present invention program better, the present invention is described in further detail below in conjunction with drawings and embodiments.
With reference to Fig. 2, Fig. 2 shows the realization flow of the method for terminal access idle mode of the present invention, may further comprise the steps:
Step 201: during terminal access idle mode, terminal and network side are consulted idle pulley and are kept information.
The present technique field personnel know, terminal can send message to its Current Serving BTS, and request enters idle pulley, and Current Serving BTS also can initiatively require terminal access idle mode by sending message.Therefore, when terminal initiatively requires to enter idle pulley, can enter request message by idle pulley and send its idle pulley reservation information of determining to network side.By the interacting message between terminal and its Current Serving BTS, Current Serving BTS and the rear end network element ASN GW, notice paging controller terminal access idle mode, and in the location register of correspondence, preserve state information, paging information and the service stream information of terminal.Therefore, in the present invention, whether can omit the access step in the time of can at first reentrying according to the definite network of self algorithm decision-making, can omit which step, determine that according to these omissible access steps the idle pulley that needs keep keeps information then by terminal.Unlike the prior art be, these idle pulleys keep information and have not only comprised the indication of idle pulley reservation information, be 8bit information of the prior art, but also the terminal network that has comprised each bit indication relevant administrative messag pairing parameter of omissible step, i.e. relevant terminal contextual information when reentrying.Such as, some relevant information of following steps are arranged:
If omit SBC_REQ/RSP (ability negotiation request/response) step, the ability parameter collection relevant of the MS that obtains when then needing to keep network side related entities, service ASN-GW, anchor ASN-GW that BS or BS connected with the SBC_REQ process with its MS originally that safeguards networking;
If omit PKM_REQ/RSP (authentication request) step, then need to keep the security-related of MS that network side related entities, service ASN-GW, anchor ASN-GW that BS or BS connected obtain when its MS originally that safeguards is networked, and the parameter set relevant with PKM_REQ, comprise state machine information, SA (Security Association), SAID (Security Association sign), the TEK key of encrypting traffic (be used for) of some keys etc., also need to keep the security information that relates to simultaneously;
If omit REG_REQ/RSP (register requirement/response) step, the MAC relevant (medium access control) the ability parameter collection of the MS that obtains when then needing to keep network side related entities, service ASN-GW, anchor ASN-GW that BS or BS connected with the REG_REQ process with its MS originally that safeguards networking.
Certainly, according to actual needs, can also keep some other information, describe no longer one by one at this.
After the terminal idle pulley reservation information that needs keep when decision-making has been determined to enter idle pulley according to self algorithm, can when its active request enters idle pulley, these idle pulley reservation information be sent to network side; By idle pulley reservation information indication and the network side algorithm decision-making of network side according to terminal, the idle pulley of tectonic network side keeps information then.Because the decision-making of the algorithm of network side might be different with the algorithm decision-making of terminal, therefore, need terminal and network side to carry out the negotiation that idle pulley keeps information, to satisfy the demand of different decision-makings.
After the indication of idle pulley reservation information and the decision-making of network side algorithm of network side integrated terminal, omissible step when determining the terminal network re-entry, thereby construct and these step relevant terminal contextual informations, then these information and the indication of idle pulley reservation information are sent to terminal simultaneously, finish the negotiations process that terminal and network side idle pulley keep information.
If when terminal enters idle mode request to the network side transmission, determine the indication of idle pulley reservation information, then network side also can determine that the indication of idle pulley reservation information reaches the contextual information of the terminal corresponding with it according to the action of self.Then, network side sends to terminal with its idle pulley reservation information of determining, finishes the negotiations process that terminal and network side idle pulley keep information.
The front is mentioned, and terminal not only can active request enter idle pulley, also can enter idle pulley according to the indication of Current Serving BTS.In this manner, when network side also can enter idle pulley by indicating terminal, its idle pulley reservation information of determining is sent to terminal, finish the negotiations process that terminal and network side idle pulley keep information.
Step 202: the idle pulley after will consulting keeps information and is kept at terminal and network side respectively.
Its Current Serving BTS can obtain these idle pulleys and keeps information when making the terminal network re-entry, reduces unnecessary interaction flow, these information need be kept at terminal and network side respectively.Network side is saved in the idle pulley reservation information of its structure on the anchor paging controller of described terminal.Terminal need be upgraded the parameter information of its preservation according to the idle pulley reservation information indication of network side.
Because the mobility of terminal, when exitting from idle mode the network reentry, terminal may roam in the other paging group, at this moment, network is reentried if desired, then paging controller need be initiated beep-page message according to the paging group at the current place of terminal, therefore needs a LR (location register) to preserve state information, paging information and the service flow relevant information of terminal.Also above-mentioned idle pulley reservation information can be kept among this LR.Paging controller can corresponding one or more LR logic entities, and paging controller and its corresponding LR logic entity can be realized in a physical NE.
Message interaction process when Fig. 3 shows terminal access idle mode among the present invention:
1. when the terminal decision enters idle pulley, send DREG_REQ (the idle pulley request of entering) message to PA/SBS (paging agent/base station), in this message, carry idle pulley and keep information, before this terminal according to self algorithm decision-making look ahead whether omit the access step when network is reentried, and which step of decision-making omission, idle pulley is set then keeps information.
2.PA/SBS receiving the idle pulley that terminal sends enters after the request message, according to the network side algorithm, agree terminal access idle mode, and send MSS Info Request (end message request) message to Anchor DPF/FA (anchor datapath function body/external agent) by Relay PC/DPF (relaying paging controller/datapath function body); Anchor DPF/FA responds MSS Info Response (end message response) message by Relay PC/DPF to PA/SBS.
3.PA/SBS after receiving MSS Info Response message, send Data path Release Request (data channel discharges request) message by Relay PC/DPF to AnchorDPF/FA, and in this message, carry the base station and indicate the idle pulley of the network side of determining to keep information according to the idle pulley reservation information of decision-making of network side algorithm and terminal.
4.Anchor DPF/FA sends its idle pulley reservation information of determining to Anchor PC/LR (anchor paging controller/location register) by MSS Info Request (end message request message); Anchor PC/LR is saved in the idle pulley reservation information of receiving in the location register; Respond MSS Info Response message to Anchor DPF/FA then.
5.Anchor after DPF/FA receives MSS Info Response message, send Data path Release Response (data channel discharges response) message to PA/SBS by Relay PC/DPF.
6. network side is indicated according to Termination ID LE MODE RETAIN INFO, after the information that corresponding steps is relevant remains into Anchor PC, according to the actual conditions that keep, the idle pulley reservation information of tectonic network side is indicated, and sends to terminal by DREG_CMD (idle pulley enters response) message.
The information that it was preserved before terminal was upgraded according to the latest development of idle pulley reservation information; If consistent, then need not revise, if inconsistent, then adjust accordingly; Omit the PKM_REQ step as the terminal original request, and network side does not remain into associated information Anchor PC or AnchorAuthenticator preservation, then the idle pulley of network side in DREG_CMD message keeps in the information indication information and can carry out can not ignoring the PKM_REQ/RSP process when network is reentried by indicating terminal, and terminal will be deleted the state machine information of association key so.
7.PA/SBS send Data path ReleaseAck (data channel discharges and confirms) message by Relay PC/DPF to Anchor DPF/FA, after Anchor DPF/FA receives this message, discharge related resource.
In said process, when if terminal access idle mode sends DREG-REQ, do not determine the indication of idle pulley reservation information, network side can be according to the action of self so, initiatively and directly send the indication of idle pulley reservation information, the passive information of adjusting its preservation as indicated of terminal gets final product.
With reference to Fig. 4, Fig. 4 shows the realization flow of the method for terminal network reentry of the present invention, may further comprise the steps:
Step 401: terminal is initiated network reentry request to its current serving BS.
After terminal exits from idle mode or carrying out position renewal and position renewal failure under the idle pulley, need guiding terminal to carry out network re-entry procedure.At this moment, terminal need be initiated network reentry request to its current serving BS.
Step 402: after the network reentry request of terminal transmission is received in the base station, obtain the idle pulley reservation information of this terminal of its reservation from the anchor paging controller of this terminal.
Because the mobility of terminal, exit from idle mode at it and to carry out network when reentrying, base station when its Current Serving BTS enters idle pulley with it may not be same base station, therefore, the idle pulley that Current Serving BTS need obtain this terminal of its reservation from the anchor paging controller of this terminal keeps information, so that omit the step that can save according to these information, simplifies the interacting message in the terminal network reentrant procedure, save terminal and Internet resources, improve network reentry speed.
The front is mentioned, when terminal access idle mode, omissible step and the relevant administrative messag pairing parameter corresponding with these steps when its network being reentried, just said idle pulley keeps information, has been kept on the anchor paging controller of this terminal.The base station can obtain the idle pulley reservation information of this terminal of its reservation from the anchor paging controller of this terminal according to the ID (sign) of this terminal.
At first, the base station sends end message request message, the id information of carried terminal in this message by the relaying paging controller to the anchor paging controller of this terminal; After the anchor paging controller of terminal is received this request message, from the information of its preservation, find out idle pulley that should terminal is kept information; Then, send the end message response message to described base station, and in this message, carry described idle pulley reservation information by the relaying paging controller.
Step 403: the base station keeps the information guide terminal according to the idle pulley that obtains and finishes the subsequent network reentrant procedure.
After the Current Serving BTS of terminal gets access to the idle pulley reservation information of this terminal, promptly know when this terminal network is reentried and to omit which step, carry out just can omitting these steps when network is reentried at guiding terminal, and the information of the required acquisition of these steps has also obtained from idle pulley reservation information, and terminal itself has also kept these information, therefore, when omitting these steps, can not influence the information requirement of terminal and network side.
Fig. 5 shows exit from idle mode message interaction process in the network re-entry procedure of terminal among the present invention:
1. paging: after network side has data to arrive, trigger the anchor paging controller of this terminal correspondence and initiate paging.The anchor paging controller can be given it for change and keep terminal place paging group information, initiates the paging to terminal.
2. terminal is paged arrive after, initiate the network request of reentrying, send RNG_REQ (inserting request) message to PA/SBS.
Send MS INFO Request message 3.PA/SBS pass through Relay PC/DPF (relaying paging controller/datapath function body) and/or Anchor SFA (anchor management service flow entity) and/or Anchor DPF/FA (anchor datapath function body/external agent) to Anchor PC/LR, obtain the terminal contextual information that Anchor PC is kept to Anchor PC.The information of obtaining in this process comprises the indication of idle pulley reservation information, the relevant context parameters of omissible step when carrying idle pulley simultaneously and keeping the indicated terminal network of information and reentry, these parameters are according to sphere of action, keep among service ASN-GW that can connect in base station and base station and the anchor ASN-GW.
4.PA/SBS obtain the contextual information that it should be safeguarded, promptly in MS Info Response (end message response) message, can carry following information:
The Anchor Authenticator ID of this terminal or directly obtained the Ak (KI) and the AK context of this terminal; The legitimacy that is used for BS checking RNG_REQ;
Idle pulley keeps information, comprises the relevant context parameters of omissible step when the indicated terminal network of idle pulley reservation information is reentried simultaneously.
5. service flow renewal process.Consider and do not keep service flow information in the terminal access idle mode process; Perhaps kept service flow information, but since terminal network when reentrying the current service BS and the service service flow empowerment management entity at place upgrade according to the local policy needs, need to carry out the service flow renewal process so.Renewal process comprises service flow empowerment management entity to strategic server initiation service flow position updating process, and follow-up strategic server is carried out the resource reservation request process of the prefabricated stream of this terminal according to the authorization conditions of this terminal.
In this process, service service flow empowerment management entity will carry out register update to the anchor service flow empowerment management entity of terminal simultaneously, so that the follow-up needs of anchor service flow empowerment management entity send administrative messag can for corresponding service flow empowerment management entity when setting up service flow.
Strategic server sends resource reservation request message to anchor management service flow entity, and carries the relevant quality of service requirement information of prefabricated stream of this terminal in this message; Anchor management service flow entity sends to the base station with the resource reservation request message of receiving by described relaying paging controller; Resource reservation is carried out according to this quality of service requirement information in the base station.
6. the base station is according to above information and the local policy of oneself and the policy information that obtains from service ASN-GW, the flow process that the terminal network of further making a strategic decision is reentried, promptly whether can omit and omit which step, structure HO Process Optimization TLV (handoff procedure optimization indication, be used for eating dishes without rice or wine to inform the omissible step indication of terminal network reentrant procedure) send RNG_RSP (inserting response) message to terminal, in this message, can carry the Basic CID (basic connection identifier) that gives this terminal distribution in new base station, Primary Management CID (main management connecting identification).If the base station has obtained the service flow information of this terminal, then can further upgrade these service flow corresponding parameters information, as information such as the CID that upgrades and/or SFID.Do (these service flow lastest imformations need to send to terminal?)
7. the subsequent network access procedure is finished according to the information guide terminal that obtains in the base station.
Terminal is then according to the HO Process Optimization TLV among the RNG-RSP that receives, and the information of carrying in the RNG-RSP message, upgrade its inner context that keeps, as CID (connection identifier), the SFID (service flow sign) of related service stream, and/or new base station is to Basic CID (basic connection identifier), the Primary Management CID information such as (main management connecting identifications) of its distribution.
8. terminal and base station are carried out data channel and are set up process after the access procedure of eating dishes without rice or wine is finished in the network reentry.
9, after above step executes, the contextual information that this terminal idle pulley that mobile IP external agent FA will notify the anchor paging controller of this terminal to delete its reservation is withed a hook at the end down.
