Description
Technical field
The present invention relates to micro-wave access to global intercommunication (Worldwide Interoperability for MicrowaveAccess, be called for short WiMAX) system, more particularly, relate to the update method of mobile station paging-information in a kind of WiMAX system.
Background technology
Micro-wave access to global intercommunication is based on the wireless MAN access technology of IEEE 802.16 standards.Along with the extensive use of the flourish and wireless network of internet service, the WiMAX system has obtained a large amount of application and concern with its good wireless access characteristic.
When WiMAX was applied to mobile communication, its system comprised access service network (Access ServiceNetwork is called for short ASN) and connectivity serving network (Connectivity Service Network is called for short CSN).Wherein ASN is used to the WiMAX terminal that the network function set of wireless access service is provided, comprise base station (Base Station, be called for short BS) and access service network gateway (Access Service NetworkGateway, ASN-GW), a plurality of ASN can form an Internet Service Provider (Network AccessProvider is called for short NAP); CSN is used to the WiMAX terminal that Internet Protocol (InternetProtocol is called for short IP) Connection Service is provided, and comprises home agent (Home Agent is called for short HA).
As shown in Figure 1, mobile radio station (Mobile Station is called for short MS) is serving BS (Serving BS is called for short SBS) through the BS of R1 interface access; For this MS, the ASN-GW with this SBS is connected through the R6 interface is its service access service network gateway (Serving ASN-GW is called for short SGW); The ASN-GW that Interface R3 between the HA from ASN to CSN is provided is anchor access service network gateway (Anchor ASN-GW is called for short AGW).AGW and SGW can be located in the identical or different equipment.
Network work group second stage (NWG Stage2) regulation, when a service ending, when MS will enter idle pulley, provide service by its SGW and AGW, and by authenticator (authenticator) authentication that has among the 3rd ASN-GW of call controller/location register/authenticator's function (PC/LR/Authenticator), this authenticator is the grappling authenticator (anchoredAuthenticator) of MS, promptly as the authenticator of NAP external agent's (Foreign Agent, be called for short FA) the MS that AGW stored.
When MS entered idle pulley, the 3rd ASN-GW created a PC inlet, and the data forwarding Bearer Channel between the SBS of MS, SGW and the AGW is removed.
After MS enters idle pulley, when HA will connect this MS, issue down link data to external agent AGW, this AGW finds that this MS is in idle pulley, then sends mobile station information request (MSInfo Req) to relevant information such as moving station mark (MSID), the paging indication (paging ind) etc. of PC/LR/anchored Authenticator to obtain MS.PC/LR/anchored Authenicator replys the mobile station information that has these information and responds (MS Info Rsp) to AGW, indicates this MS service of being authorized to.This moment, PC obtained this MS current position information from LR, i.e. its paging group sign (PGID), and transmission page notification is to all ASN GW in this paging group (PG) scope.These ASN GW will go to its each auto correlation and belong to the BS of this appointment paging group after receiving page notification before this page notification.These BS send BS broadcast paging messages (BS Broadcast Paging Message) paging MS, require it to exit from idle mode.
In a NAP of WiMAX system, have under the situation of a plurality of paging controller/location registers at present, as shown in Figure 2, it is unique that paging in the paging group scope of each paging controller/location register control is identified in the NAP, like this, in above-mentioned paging, can directly find the paging group of this MS according to the current paging group sign of MS.And, because paging controller/location register is positioned at authenticator (among the 3rd ASN-GW), in said process, FA preserves authenticator's position, when FA triggering paging was served MS again, the authenticator can directly obtain the information of mobile radio station from paging controller.
Yet in a this NAP, have under the situation of a plurality of paging controller/location registers, the interior paging sign of paging group scope of each paging controller/location register control is set uniquely, waste very much resource.If but the paging in the paging group scope of paging controller/location register control identifies when repeating to be provided with, when FA triggers paging and is in MS under the idle pulley, because the MS of this moment may roam into from the paging group scope of former paging controller control in the paging group scope of another paging controller control, although the paging group sign may be constant, but the paging group of this moment sign has not been that paging controller distributed or controlled by original, therefore can't directly find the paging group of this MS according to the paging group sign of MS, just can not continue to support the function of paging MS.
And if under authenticator and paging controller/location register separation case, the authenticator more can't obtain the residing new paging controller of MS/location register address, therefore can't obtain the information of mobile radio station, thereby can not support paging MS.
