The method and device provided in the present invention realize the MIP de-registration process by the MS in idle mode.
Description
Technical field
The present invention relates to travelling carriage (MS) in the communication system and carry out mobile internet protocol (MIP) and remove registration technology, particularly a kind of MS carries out MIP and removes process registration and device.
Background of invention
MS in communication system is paged or when not making a call, and can enter Idle Mode; MS in communication system carries out paged or makes a call etc. when professional, can enter non-IdleMode.Below be that World Interoperability for Microwave Access, WiMax technology (WiMAX) network is that example is elaborated with the communication system.
Fig. 1 is the structural representation of WiMAX network, the WiMAX network comprises access service network (ASN) and connectivity serving network (CSN), wherein, comprise base station (BS), authentication entity (Authentication), Foreign Agent (FA), relaying paging control entity (Relay PC), anchor paging control entity (Anchor PC), Location Registration device (LR) and ASN function (ASN Functional) entity that MS, MS are affiliated among the ASN; Comprise local agent (HA) among the CSN.MS is under Idle Mode, and Anchor PC and LR can be integrated into an entity, and Anchor PC and Relay PC are used for by the BS paging MS under the MS; Authentication is used for MS is carried out authentication, and LR is used for MS is carried out location registers.ASN Functional entity is used for triggering to MS professional.HA and FA carry out interacting message by the R3 link that is provided with for MS, carry out interacting message by the R4 link that is provided with for MS between FA and the Anchor PC/LR and between Anchor PC/LR and the Authentication.Here, also can not distinguish Relay PC and Anchor PC, and be commonly referred to as PC.
At present, MS can pass through internet protocol (IP) link and transmit information, and internet working group has formulated MIP, and MIP can be connected on any link the MS that supports MIP with the MS sign of setting for MS provides a kind of IP routing mechanism.Support the MS of MIP changing the geographical position under the situation of not interrupting the information that transmits by link or under the situation about not restarting.
There are two kinds of technology can make MS support MIP.First kind of technology is referred to as client and moves internet protocol (CMIP, Client Mobile Internet Protocol) technology, and this technology is integrated in the MIP function among the MS, and it all is to be initiated by MS that the MIP registration/MIP of MS goes registration process.Second kind of technology is referred to as to act on behalf of mobile internet protocol (PMIP, Proxy Mobile InternetProtocol) technology, in the proxy mobile node (Proxy Mobile Node) of this technology with MIP function setting ASN under MS, MIP registration/the MIP of MS goes registration process to be initiated by Proxy Mobile Node, and Proxy Mobile Node generally is integrated in the Authenticator entity.
At present, the MS under busy pattern (Idle Mode) adopts the PMIP technology to initiate MIP and removes the process registration flow chart as shown in Figure 2, and its concrete steps are:
The service disconnection of step 200, ASN Functional entity triggers MS, the Proxy Mobile Node of ASN sends and discharges the R3 link request message under MS, and the R3 link is the link of setting up for MS between FA and the HA.
Step 201, Proxy Mobile Node send the MIP login request message to FA, and the MIP life cycle (Lifetime) that this message is carried is 0.
When the MIP Lifetime that carries when the MIP login request message was 0, what in fact send went login request message for MIP.
Step 202, FA will receive, and to carry MIP Lifetime be that 0 MIP login request message is transmitted to HA.
R3 link between that step 203, HA will be provided with for MS and the FA is removed, and returns MIP register requirement response message to FA.
Step 204, FA return MIP register requirement response message to Proxy Mobile Node.
Step 205, Proxy Mobile Node return to ASN Functional entity and discharge R3 link request response message, and the R3 link is removed and finished.
MS under non-Idle Mode adopts the CMIP technology to initiate MIP and removes the process registration flow chart as shown in Figure 3, and its concrete steps are:
The service disconnection of step 300, ASN Functional entity triggers MS sends release R3 link request message to FA.
Step 301, the FA that receives this request message send to ASN Functional entity and receive the response.
Step 302, FA send mobility advertisement (Mobility Advertisement) message to MS, and it is 0 that this message is carried MIP Lifetime.
Step 303, MS send the MIP login request message to FA, and it is 0 that this message is carried MIPLifetime.
Step 304, FA will receive, and to carry MIP Lifetime be that 0 MIP login request message is transmitted to HA.
R3 link between that step 305, HA will be provided with for MS and the FA is removed, and returns MIP register requirement response message to FA.
Step 306, FA return MIP register requirement response message to MS.
Step 307, FA return to ASN Functional entity and discharge R3 link request response message, and the R3 link is removed and finished.
Fig. 2 and MIP deregistering method shown in Figure 3 are that MS carries out under non-Idle Mode, yet, but also there be not the MIP of MS under Idle Mode to remove registration technology at present.
There is not the MIP of MS under Idle Mode to go registration technology can have many defectives, as not triggering the WiMAX network side is that the technology of the deletion of the related resource that is provided with of MS (comprises two kinds of situations, a kind ofly under Idle Mode, lose for MS, another kind is not lost under Idle Mode for MS), the R3 links that are provided with for MS between picture dismounting FA and the HA etc., this might cause the wasting of resources.Below can't to delete the WiMAX network side to MS after losing under the Idle Mode be that the reason of the related resource that is provided with of MS is elaborated.
When MS under Idle Mode, the WiMAX network side requires MS to initiate Location Updated flow process according to different LocationUpdated conditions, be that MS passes through affiliated BS and Relay PC sends position updating request (Location Update Request) to Anchor PC/LR, AnchorPC/LR is that MS carries out Location Updated.Different Location Updated conditions comprise: 1) paging group is upgraded (Paging Group Update), and the paging group (Paging Group) that detects self storage as MS under Idle Mode is carried out Location Updated when inequality with the Paging Group at current place; 2) timer upgrades (Timer Update), the timer expiry that is provided with under Idle Mode as MS and carry out period L ocation Updated; 3) (PowerDown Update) upgraded in power down, and MS is being restarted after the power down under the Idle Mode, carries out Location Updated; 4) skip threshold is upgraded (MAC Hash Skip Threshold Update), carries out Location Updated when MS is carrying out MAC Hash Skip Threshold Update under the Idle Mode after.
When FA receives the packet of the MS that HA sends, can notify Anchor PC/LR, detect MS by Anchor PC/LR and be in following time of Idle Mode, MS is initiated the paging flow process, paging is that MS sends packet to MS.
No matter the WiMAX network side is to carry out LocationUpdated or to carry out paging the MS under Idle Mode, all need MS under Idle Mode, if MS is not under IdleMode, promptly the MS under Idle Mode loses, the problem or the WiMAX network side that will cause the WiMAX network side can't carry out Location Update owing to do not receive the Location Update Request that MS sends in timing cycle are the Paging flow process failure that MS carries out, Paging can't send the problem of packet for MS less than MS.
Though, cause the WiMAX network side to carry out Location Updated or to cause WiMAX network side paging MS failure owing to losing to the MS under Idle Mode at the MS under the Idle Mode, but, the WiMAX network side is also safeguarding to be the related resource that MS is provided with, as safeguarding between FA and HA the R3 link that is provided with for MS etc., this can cause the waste of WiMAX network side resource.
Summary of the invention
The embodiment of the invention provides a kind of MS to carry out MIP and removes process registration and device, can be implemented in MS under the Idle Mode and carry out MIP and go registration.
