A kind of mobile station moves the method and device of internet protocol registration
A kind of mobile station moves the method and device of internet protocol registration
Technical field
The present invention relates to the mobile station in communication system（MS internet protocol) is moved（MIP registration technology) is removed, more particularly to a kind of MS carries out the method and device that MIP goes registration.Background of invention
When MS in a communications system is not paged or does not initiate calling, Idle Mode can be entered;When MS in a communications system is paged or initiated the business such as calling, non-Idle Mode can be entered.Below using communication system as World Interoperability for Microwave Access, WiMax technology（WiMAX 4) are entered exemplified by network in detailed description.
Fig. 1 is the structural representation of WiMAX network, and WiMAX network includes access service network（) and connectivity serving network ASN（CSN), wherein, ASN includes the base station belonging to MS, MS（BS), authentication entity（Authentication), Foreign Agent（FA paging control entity), is relayed（Relay PC), anchor paging control entity（Anchor PC), location registration device（) and ASN functions LR（ASN Functional) entity；CSN includes local agent（HA ).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 pagings MS belonging to MS;Authentication is used to authenticate MS, and LR is used to carry out location register to MS.ASN Functional entities are used to trigger business to MS.HA and FA carries out carrying out interacting message between interacting message, FA and Anchor PC/LR and by the R4 links set for MS between Anchor PC/LR and Authentication by the R3 links set for MS.Herein, Relay PC and Anchor PC can also not be differentiated between, and are commonly referred to as PC.
At present, MS can pass through internet protocol（IP) link transmission information, internet working group has formulated MIP, and MIP provides a kind of IP routing mechanisms for MS, support MIP MS is confirmed this It can be connected to the MS marks of setting on any link.Geographical position can be changed in the case where not interrupting by link transmission information or in the case of not restarting by supporting MIP MS..
There are two kinds of technologies that MS can be made to support MIP.The first technology is referred to as client movement internet protocol（CMIP, Client Mobile Internet Protocol) technology, MIP functions are integrated in MS by the technology, and MS MIP registrations MIP go registration process to be initiated by MS.Second of technology is referred to as to act on behalf of mobile internet protocol（PMIP, Proxy Mobile Internet Protocol) technology, the technology is by MIP function settings in the affiliated ASN of MS proxy mobile node (Proxy Mobile Node), MS MIP registrations/MIP go registration process to be initiated by Proxy Mobile Node, and Proxy Mobile Node are typically integrated in Authenticator entities.
At present, in non-idle mode（Idle Mode) under MS using PMIP technologies initiate MIP go registration method flow diagram as shown in Fig. 2 it is concretely comprised the following steps：
The service disconnection of step 200, ASN Functional entity triggers MS, release R3 link request messages are sent to the affiliated ASN of MS Proxy Mobile Node, and R3 links are the links set up between FA and HA for MS.
Step 201, Proxy Mobile Node send MIP registration request message, the MIP life cycles that the message is carried to FA（Lifetime it is) 0.
When the MIP Lifetime that MIP registration request message is carried are 0, what is actually sent goes login request message for MIP.
The carrying MIP Lifetime received are transmitted to HA by Bu Sudden 202, FA for 0 MIP registration request message.
The R3 link downs between FA set for MS are returned to MIP registration request response message by Bu Sudden 203, HA to FA.
Step 204, FA return to MIP registration request response message to Proxy Mobile Node.Walk gland 205, Proxy Mobile Node and return to release R3 to ASN Functional entities υ j J link requests ring multitudinous message, and R3 link downs are completed.
MS under non-Idle Mode initiates MIP using CMIP technologies and removes the method flow diagram of registration as shown in figure 3, it is concretely comprised the following steps：
The service disconnection of step 300, ASN Functional entity triggers MS, release R3 link request messages are sent to FA.
Step 301, receive the FA of the request message and sent to ASN Functional entities and receiveed the response.
Step 302, FA send mobility advertisement to MS（Mobility Advertisement) message, it is 0 that the message, which carries MIP Lifetime,.
Step 303, MS send MIP login request messages to FA, and it is 0 that the message, which carries MIP Lifetime,.
The carrying MIP Lifetime received are transmitted to HA by step 304, FA for 0 MIP registration request message.
The R3 link downs between FA set for MS are returned to MIP registration request response message by step 305, HA to FA.
Step 306, FA return to MIP registration request response message to MS.
Step 307, FA return to release R3 link request response messages to ASN Functional entities, and R3 link downs are completed.However, the current MIP but also without MS under Idle Mode removes registration technology.
There is no MIPs of the MS under Idle Mode to go registration technology there are many defects, technology of the WiMAX network side for the deletion of the MS related resources set is not triggered such as（Including two kinds of situations, for MS, the Lost Xia Idle Mode loses one kind, another not lost under Idle Mode for MS）, as being MS R3 links set etc. between dismounting FA and HA, this is possible to that the wasting of resources can be caused.WiMAX nets can not be deleted after being lost below to MS under Idle Mode The reason for network side is the related resource of MS settings is described in detail.
When MS is under Idle Mode, WiMAX network side requires that MS initiates Location Updated flows according to different Location Updated conditions, i.e. MS sends position updating request by affiliated BS and Relay PC to Anchor PC/LR（Location Update Request), Anchor PC/LR are that MS carries out Location Updated.Different Location Updated conditions include：1) paging group updates (Paging Group Update), when MS detects the paging group of itself storage under Idle Mode（Paging Group) Location Updated are carried out when being differed with the Paging Grou that are currently located;2) timer updates（Timer Update), when the timer expiry that MS is set under Idle Mode carries out period L ocation Updated;3) power down updates (Power Down Update), and MS is restarted under Idle Mode after power down, carries out Location Updated;4) skip threshold updates（MAC Hash Skip Threshold Update), Location Updated are carried out after MS performs MAC Hash Skip Threshold Update under Idle Mode
When FA receives the MS of HA transmissions packet, Anchor PC/LR can be notified, when detecting MS under Idle Mode by Anchor PC/LR, paging flow is initiated to MS, paging, to MS, is that MS sends packet.
No matter WiMAX network sides are that Location Updated are carried out to the MS under Idle Mode or paging is carried out, MS is required under Idle Mode, if MS is not under Idle Mode, MS Lost i.e. under Idle Mode lose, WiMAX network side be may result in due to not receiving the Location Update Request of MS transmissions in timing cycle and the Paging flows failure that to be MS carried out of the problem of Location Update can not be carried out or WiMAX network side, Paging is less than MS, the problem of packet can not being sent for MS.
Although, due under Idle Mode MS Lost lose and cause WiMAX Wang Network sides can not under Idle Mode MS carry out Location Updated or cause WiMAX network side paging MS fail, but, WiMAX network side also maintains the related resource set for MS, the R3 links set between FA and HA for MS are such as maintain, this can cause WiMAX The waste of network side resource.The content of the invention
The embodiment of the present invention provides a kind of MS and carries out the method and device that MIP goes registration, can realize that the MS under Idle Mode carries out MIP and goes registration.
A kind of mobile station MS moves the method that internet protocol MIP goes registration, and the MS is under idle pulley Idle Mode, and this method includes：
