Problems solved by technology

[0006] 1. When the MS moves to a new access service network (ASN), the new ASN will require the MS to migrate its corresponding Anchor PC locally for management, but the existing technology does not provide a corresponding method for migrating the Anchor PC , so obviously this requirement cannot be satisfied;
[0007] 2. The Relay PC associated with the PG or BS where the MS moves will set its corresponding Anchor PC. When the Anchor PC requests to migrate the original AnchorPC corresponding to the MS, it is obvious that the existing technology cannot realize the Anchor PC. Migration of PCs that cannot meet this requirement;
[0008] 3. The route from the new Relay PC to the original Anchor PC is complicated, or the link is not optimal (such as frequent congestion, link disconnection, etc.), which may cause excessive delay in the subsequent paging or MS reentry process. For Anchor PC migration, the existing technology cannot meet this requirement due to the inability to realize the migration of Anchor PC
[0009] If the above situation occurs or due to other reasons, it is required to migrate MS Anchor PC, which cannot be realized by existing technology

Embodiment 1

[0041] see figure 2 , Anchor PC migration process includes:

[0042] Step 201:

[0043] After the MS in IDLE mode initiates a location update operation. The MS will send a ranging request message (RNG_Req) ​​to its new base station (BS), which includes: location update request information (Location Update Indication), paging controller identification information (PCID) and authentication information ( HMAC / CMAC). Wherein, PCID is the identification information of the Anchor PC of the MS, indicating that the RNG_Req message is used for location update.

[0044] Step 202:

[0045] After receiving the RNG_Req message from the MS, the BS notifies the RelayPC through the PA that a new MS has entered. The PA sends a location update request message (LU Req) to the Relay PC, which includes: the identification information (MSID) of the MS, the identification information (PCID) of the Anchor PC of the MS, and the identification information of the base station to which the MS belon...

Embodiment 2

[0070] see image 3 , Anchor PC migration process includes:

[0071] Step 301:

[0072] When the MS in IDLE mode initiates a location update operation, the MS will send a ranging request message (RNG_Req) ​​to its new base station (BS), which includes: location update request information (LU_REQ), and the paging controller The flag information (PCID) and authentication information (HMAC / CMAC). The PCID is the Anchor PC ID serving the MS, indicating that the RNG_Req message is used for location update.

[0073] Step 302:

[0074] After receiving the RNG_Req message from the MS, the BS notifies the RelayPC through the PA that a new MS has entered. The BS / PA sends a location update request message (LU Req) to the RelayPC, which includes: the identification information (MSID) of the MS, the identification information (PCID) of the Anchor PC of the MS, and the identification information of the base station to which the MS belongs (BSID) and an indication message whether it has...

Embodiment 3

[0102] see Figure 4 , Anchor PC migration process includes:

[0103] Step 401

[0104]When the MS in IDLE mode triggers a location update operation, the MS will send a ranging request message (RNG_Req) ​​to its current base station (BS), which includes: location update request information (LU_REQ), paging controller Flag information (PCID) and authentication information (HMAC / CMAC). The PCID is the Anchor PC ID serving the MS, indicating that the RNG_Req message is used for location update.

[0105] Step 402:

[0106] After receiving the RNG_Req message from the MS, the BS notifies the RelayPC through the PA that a new MS has entered. The BS / PA sends a location update request message (LU Req) to the RelayPC, which includes: the identification information (MSID) of the MS, the identification information (PCID) of the Anchor PC of the MS, and the identification information of the base station where the MS is currently located ( BSID) and an indication message whether it ha...

Abstract

The provided method for transferring the Anchor PC to MS comprises: A. the idle MS triggers the position update operation, sends the update request through current BS to the NS; according to pre-set transfer condition for Anchor PC, NS determines its necessary to transfer the Anchor PC, and obtains the MS message from original Anchor PC; and B. NS builds message for MS in the new Anchor PC, updates the Anchor PC mark message for storing in MS, and cancels original relative MS message.

Description

technical field [0001] The invention relates to the technical field of wireless metropolitan area network, in particular to a method for migrating an anchor paging controller to a mobile station. Background technique [0002] In the mobile broadband wireless access system defined by the IEEE 802.16e standard, the MS can work in an idle (IDLE) mode. When the MS works in idle mode, the MS can move within a set area without sending uplink services. At the same time, the MS receives downlink broadcast service messages at regular intervals to determine whether there is currently a downlink service provided to The MS. In the set area, when an MS in IDLE mode roams from one cell to another, it does not need to register with the base station (BS) in the cell before roaming in the cell after roaming, and, when the MS is in When roaming between different cells, there is no need to perform operation procedures such as handover, which helps to save power and air interface resources of...
