Identification; then the received relay station identity and tracking area identifier are recorded in the first correspondence.
- the first correspondence may be recorded in a mapping table, or a database, to facilitate the query.
- An example of a paging method incorporating the location update method in the above embodiment will be described below.
- 4 is a flowchart of a paging method in this example; in this example, the relay station Relay_c is a mobile relay station, and the terminal UE-i is a terminal under the mobile relay station, in order to complete the paging of the terminal UE-i, the entire process It can be divided into three phases, including:
- Step 401 Relay_c moves into the cell of the eNB.
- Step 402 Relay_c sends a control message Control_Message-1 to the eNB.
- Control_Message-1 Relay_c reports its relay identity Relay_ID and tracking area identifier TA_c to the eNB.
- Step 403a-b the eNB internally stores a mapping table of the mapping relationship between the tracking area and the relay station: (TA_Rate) mapping table, where the mapping table stores the first correspondence.
- the eNB After receiving the Control_Message_1, the eNB first updates the (TA_Relay) mapping table according to the information therein, and then the eNB sends a control message on the S1-MME interface to the MME, for example, ENB-CONFIGURATION-UPDATE, this
- the control message includes the identity identifier eNB ID of the eNB and the tracking area identifier TA_c of Relay_c.
- the MME can know that the Relay-c is now camped in the cell of the eNB.
- Step 404 A specific terminal UE-i enters a PP-C cell.
- Step 405 The Relay_c broadcasts its own identity Relay-ID and tracking area identifier TA-c through the system message in its own cell.
- Step 406 After receiving the system message broadcasted by the Relay-c, the UE_i sends a control message Tracking_Area_Update_Request to the Relay_c to initiate the location update process.
- the Tracking_Area_Update_Request is defined in the existing standard, and includes the identity of the terminal UE_ID and the tracking area identifier TA-c.
- Step 407 Relay_c does not process after receiving the message, but directly forwards it to Step 408: After receiving the message, the eNB does not process, but directly forwards it to the MME 0.
- Step 409 The MME maintains a list of tracking areas for each UE. After receiving the Tracking-AreaJJpdate-Request sent by UE-i, the MME adds TA_c to the tracking area list TA_List_of_UE_i of UE_i.
- TA_c the tracking area list TA_List_of_UE_i of UE_i.
- Step 410 The MME receives a paging request from the core network to UE_i.
- Step 411 The MME sends a paging message Paging to the eNB.
- the Paging message includes the identity of the UE_i UE_ID and the tracking area list of the UE_i TA_List_of_UE_i.
- Step 412 After receiving the Paging message, the eNB queries the TA-Relay mapping table according to the tracking area identifiers listed in the TA_List_of_UE_i.
- Step 413 Because TA_List_of_UE_i is likely to include only TA-c, and does not include the tracking area identifier of the eNB and other relay stations under the eNB, the eNB may only send the paging message to Relay_c to start the pair.
- Step 414 The Relay c pages the UE_i.
- the first correspondence is the correspondence between the relay stations of the base station and the tracking area of the relay station.
- the base station may also determine the second correspondence, and determine according to the second correspondence.
- the tracking area identifier in the paging message is the tracking area identifier of the base station or the tracking area identifier of the relay station under the control of the base station; wherein, the second correspondence is the relay station under the control of the base station, the tracking area of the relay station, and the resident area Correspondence between terminals of the cell under the jurisdiction of the relay station.
- the second correspondence may also be stored by the base station to facilitate its determination, and of course, may be stored by other devices, and the base station interacts with the device. It is time to determine the function. If the base station performs the storage, the base station needs to obtain the information about the relay station, the tracking area of the relay station, and the terminal that resides in the cell of the relay station. In one embodiment, the base station can move to the cell under the jurisdiction of the base station after the relay station moves. Receiving the relay station identity and the tracking area identifier reported by the relay station; and then recording the received relay station identity and the tracking area identifier into the second correspondence.
- the second correspondence may also be updated by the base station according to the relay station identity, the relay station tracking area identifier, and the terminal identity in the location update request message.
- the relay station identity can be added to the location update request message by the relay station.
- the second correspondence can also be recorded in a mapping table, or database, to facilitate the query.
- FIG. 5 is a flowchart of a method of paging in the present embodiment of FIG.;
- Relay_a is a fixed relay station
- UE- k is a terminal residing in the Relay_ a.
- the whole process can still be divided into three different stages. The differences between the flow shown in FIG. 5 and the flow shown in FIG. 4 will be mainly described below.
- step 501 to step 502 Relay_a automatically sends a control message Control_Message-1 to the eNB.
- the definition and function of the control message are the same as the Control Message l in FIG. Different from FIG. 4, in step 503a, the eNB now internally maintains a tracking area, a mapping table of the relay station and the terminal (TA_Relay_UE), and the mapping table stores the second correspondence. After receiving Control_Message-1, the eNB adds the mapping relationship between Relay_a and other tracking areas TA_a to this mapping table.
- the next phase one message (step 503b) and process are the same as in FIG.
- step 504 to move within UE_k Relay- a cell, and is similar to FIG. 4, at step 505, Relay_ a broadcast their identity and the tracking area identity within the own cell in step 506,! ⁇ —! ⁇
- the control message Tracking_Area_Update_Request is sent to Relay_a.
- Relay_a processes the message to generate a control message Control_Message_2.
- Control—Message_2 has one more parameter relative to Tracking_Area_Update_Request, that is, Relay_a's identity Relay-ID.
- Relay a sends Control_Message_2, and after receiving Control_Message_2, the eNB updates the (TA_Relay-UE) mapping table according to the information contained in the message, so that the eNB knows that UE_k is now resident.
- the community of Relay_a In the community of Relay_a.
- step 512 after receiving the Paging message, the eNB queries the (TA_Relay-UE) mapping table to determine that the UE-k is now camped in Relay-a. In the cell, therefore, in step 513, the eNB directly sends a Paging message to Relay_a, and then proceeds to step 514, and Relay_a starts paging for UE_k in its own cell.
- the eNB queries the (TA_Relay-UE) mapping table to determine that the UE-k is now camped in Relay-a. In the cell, therefore, in step 513, the eNB directly sends a Paging message to Relay_a, and then proceeds to step 514, and Relay_a starts paging for UE_k in its own cell.
- the location update request message of the terminal may be an access domain message.
- An example is given below. As shown in Fig. 6, the paging process differs from that of Fig. 5 only in phase two, so phase one and phase three are omitted in Fig. 6.
- step 601 UE_k moves into the cell of Relay_a; in step 602, UE_k receives the system message of Relay_a; and in step 603, UE_k does not send message Tracking_Area_Update_Request to Relay_a. Instead, a new defined message Control_Message_3 is sent. Because Tracking_Area_Update_Request is a non-access domain message, in Figure 5, to enable Relay-a to process this message, a large change to Relay_a is required.
- the newly designed message Control_Message-3 in Figure 6 is an access domain message, so Relay_a can process this message without much modification. Similar to the Tracking Area Update Request, Control_Message-3 includes the identity identifier UE_ID of UE k and its tracking area identifier TA_a. Subsequent steps 604-606 are similar to FIG.
