Description
Technical field
The present invention relates to the communications field, relate more specifically to redistributing and processing method of a kind of anchoring paging controller.
Background technology
Terminal (Mobile Station is called for short MS) three kinds of patterns of living in have been stipulated among the IEEE802.16: normal (NORMAL)/dormancy (SLEEP)/free time (IDLE) pattern.Wherein, the most power saving of MS under the IDLE pattern; MS need to carry out position renewal (Location Update is called for short LU) under the IDLE pattern, has four kinds of situations can trigger MS and carries out the position renewal.These situations are: paging group changes, period position upgrades, the position of shutting down is upgraded and MAC hash skip threshold upgrades.
When MS enters the IDLE pattern, network side can be selected a paging controller (Paging Controller, be called for short PC) as anchoring paging controller (Anchor PC), anchoring paging controller is used for preserving MS and enters the information that the IDLE pattern need to be preserved; When MS withdraws from the IDLE pattern, just can utilize information that Anchor PC the inside preserves to withdraw from and enter normal mode from the IDLE pattern.
When MS enters in the not professional situation of network, generally all can enter into the IDLE pattern, there is like this MS under a large amount of IDLE patterns in the network, Anchor PC will preserve the information of MS under a large amount of processing IDLE patterns.Some Anchor PC load is larger, need to share, and namely needs MS under some IDLE pattern is reassigned Anchor PC, wherein, reassigns the process of Anchor PC and carries out when period position upgrades.The flow process that period position upgrades comprises two kinds of situations: the position that has Anchor PC again to assign is upgraded and is upgraded without the position that Anchor PC assigns again.
Again the promoter who assigns the position to upgrade can be service access service network (Access Service Network is called for short ASN), relaying ASN or the AnchorPC self in the position update flow.For the again appointment of service ASN or relaying ASN initiation, current AnchorPC can accept or refuse; For the again appointment that current Anchor PC initiates, the new Anchor PC that is assigned can not accept the appointment of current Anchor PC.
The Anchor PC of no matter who initiation assigns again, as long as it is that new Anchor PC or new Anchor PC accepts oneself to be designated as new Anchor PC that current Anchor PC accepts new Anchor PC, new Anchor PC also needs the sign of oneself is notified to grappling mandate (Anchor Authenticator) ASN and grappling data channel/external agent (Anchor Datapath/Foreign Agent, be called for short Anchor DP/FA) ASN, only have Anchor Authenticator ASN and Anchor DP/FA ASN successfully to upgrade after the mark of AnchorPC, just can think and again assign Anchor PC success, Current Serving BTS could notify the MS that is under the IDLE pattern to adopt now new Anchor PC.
At present (the Network Group of network working group, be called for short NGW, it is a working group in the WiMAX Forum) discharge in (Release) agreement, for position update flow with again assign Anchor PC flow process coexistence situation, the result that serving BS not only notifies the position to upgrade by same message, if it is new Anchor PC that current Anchor PC accepts new Anchor PC, and new Anchor PC accepts oneself to be designated as new Anchor PC, then notification message also with on the mark of the Anchor PC that again assigns; But when sending this notification message, only actually is that position update flow finishes, but again assign the flow process of Anchor PC not finish, be the renewal that this time, new AnchorPC did not also notify Anchor Authenticator ASN and Anchor DP/FA ASN to finish Anchor PC sign, if the renewal process failure; MS then is an incorrect Anchor PC sign from the notification message of serving BS so.
Summary of the invention
