After the location update request message of terminal is transmitted to MME by base station, MME just can be according to the position updating request
The tracing area mark carried in message, the tracking zone list of more new terminal.In MME issuing page messages, beep-page message
In can be with the identity of carried terminal and the tracking zone list of terminal.
If it is previously noted that terminal resides in relay station jurisdiction district, can be carried in the location update request message of terminal
The tracing area mark of relay station.And because location update request message is generated and sent by terminal, then repeated station, base station
MME is forwarded to, therefore, the mode that real present position updates the tracing area mark for carrying relay station in request message can have many
Kind, for example：The tracing area mark of the relay station is obtained from the relay station by the terminal, and is added into the position
Update request message；And for example, the tracing area mark of the relay station is to be added into the location updating by the relay station
Request message；For another example, the tracing area mark of the relay station is obtained from the relay station by the base station, and is added into
The location update request message.
In one embodiment, terminal obtains the tracing area mark of relay station, Ke Yishi from relay station：Terminal is in entrance
When the jurisdiction district of station, the relay station tracing area mark of relay station broadcast is received.It can be seen that, in the prior art, terminal exists
During into relay station jurisdiction district, what relay station was broadcasted is the tracing area mark of base station, and in the present embodiment, terminal is entering
During relay station jurisdiction district, what relay station was broadcasted is the tracing area mark of relay station.In the prior art, due to the shifting of relay station
Dynamic, then in being continually changing, terminal updates continuous launch position please for the tracing area mark of the base station of relay station broadcast
Ask；And in the present embodiment, even if relay station, in movement, the relay station tracking mark of relay station broadcast is also geostationary, end
The frequency that end launch position updates request is substantially reduced, and effectively reduces the signaling traffic load that location updating brings.
Then as shown in figure 3, the present invention can also provide a kind of location updating method, its flow can include：
Step 301, relay station generation system message, the system message include the tracing area mark of the relay station
Know.
Step 302, the relay station broadcast the system message, and the terminal that triggering enters the relay station jurisdiction district is sent out
Play position updating request.
Flow shown in Fig. 3 receives the tracking area of the base station of relay station broadcast when entering jurisdiction district with terminal in the prior art
Domain identifier is different, can effectively reduce due to carrying out location updating while the next great amount of terminals of the moving belt of relay station is frequent
And the signaling traffic load for bringing.
Location updating method shown in Fig. 3 can be used alone, it is also possible to be used in combination with the paging method shown in Fig. 2,
When being used in combination, the paging of junction network is on the one hand optimized, reduce the waste of paging resource in junction network；Separately
On the one hand also prevent the overweight problem of location updating signaling traffic load caused by the addition of mobile-relay station.
Base station determines that tracing area mark in beep-page message is the tracing area mark or this base of this base station for convenience
Stand the tracing area mark of administrative relay station, in one embodiment, base station can determine the first corresponding relation, and according to first
Corresponding relation, determine tracing area mark in the beep-page message be this base station tracing area mark or this base station it is administrative
The tracing area mark of relay station；Wherein, the first corresponding relation be the administrative relay station in this base station, the relay station tracing area it
Between corresponding relation.
First corresponding relation can be stored to facilitate its to determine by base station, naturally it is also possible to be deposited by miscellaneous equipment
Storage, the determination function is realized in base station by being interacted with the equipment.If being stored by base station, then during base station need to obtain
After station, the relevant information of the tracing area of relay station, in one embodiment, base station can be moved to this base station institute in relay station
After linchpin cell, relay station identity and tracing area mark that the relay station is reported are received；Then the relay station body that will be received
Part mark and tracing area mark, charge to the first corresponding relation.
First corresponding relation can be recorded in a mapping table or database, in order to inquire about.
Combine the paging method specific implementation of location updating method in explanation above-described embodiment as an example below.Fig. 4 is
The flow chart of paging method in this example；In this example, relay station Relay_c is a mobile relay station, and terminal UE _ i is this
Terminal under mobile-relay station, to complete the paging to terminal UE _ i, whole flow process can be divided into three phases, including：
Stage one
Step 401, Relay_c are moved into the cell of eNB.
Step 402, Relay_c send a control message Control_Message_1 to eNB.In Control_
In Message_1, Relay_c reports its relay station identity Relay_ID and tracing area mark TA_c to eNB.
Step 403a-b, the eNB storage inside mapping table of one tracing area and relay station corresponding relation：（TA-
Relay）Mapping table, the mapping table stores the first corresponding relation.ENB, first can basis after Control_Message_1 is received
Information therein updates（TA-Relay）Mapping table, then eNB can to MME send a S1-MME interface on control disappear
Identity eNB_ID and Relay_ comprising eNB in breath, such as ENB_CONFIGURATION_UPDATE, this control message
The tracing area mark TA_c of c.Just can learn that present Relay_c resides in this eNB after MME receives this control message
Cell in.
Stage two
Step 404, a certain particular terminal UE_i enter the cell of Relay_c.
Step 405, Relay_c in the cell of oneself by system message broadcast oneself identity Relay_ID and
Tracing area identifies TA_c.
Control will be sent after step 406, the UE_i system message that Relay_c is broadcasted upon receipt to Relay_c disappear
Breath Tracking_Area_Update_Request（Location update request message）With launch position renewal process.Tracking_
Area_Update_Request is defined in existing standard, wherein identity UE_ID and tracing area mark comprising terminal
Know TA_c.
Step 407, Relay_c are not processed after this message is connected to, but are directly forwarded to eNB.
Step 408, eNB are not processed after this message is connected to, but are directly forwarded until MME.
Step 409, MME are that each UE maintains a list for tracing area.MME is receiving UE_i transmissions
TA_c can be added to the tracking zone list TA_List_of_UE_ of UE_i after Tracking_Area_Update_Request
i.Here, response message Tracking_Area_ of the all-network side to Tracking_Area_Update_Request in Fig. 3
Update_Response, has been omitted in figure.
Stage three
Step 410, MME receive paging request of the core net to UE_i.
Step 411, MME send beep-page message Paging to eNB.Identity UE_ comprising UE_i in Paging message
The tracking zone list TA_List_of_UE_i of ID and UE_i.
Step 412, eNB, can be according to the tracking areas listed in TA_List_of_UE_i after this Paging message is received
Domain identifier goes inquiry（TA-Relay）Mapping table.
Step 413, because there is a strong possibility in TA_List_of_UE_i only includes TA_c, and do not include eNB and eNB
The tracing area mark of other following relay stations, thus eNB this Paging message only can be sent to Relay_c so that
It starts the paging to UE_i, and is not used in paging UE_i in the cell of oneself, without other relay stations allowed below oneself
Carry out paging UE_i.
Step 414, Relay_c carry out paging to UE_i.
It is previously noted that the first corresponding relation is the correspondence between the administrative relay station in this base station, the tracing area of the relay station
Relation, in another embodiment, base station can also determine the second corresponding relation, and according to the second corresponding relation, it is determined that described
Tracing area mark is the tracing area mark of this base station or the tracing area mark of the administrative relay station in this base station in beep-page message
Know；Wherein, the second corresponding relation is the administrative relay station in this base station, the tracing area of the relay station, to reside in the relay station administrative
Corresponding relation between the terminal of cell.
Certainly, similar with the first corresponding relation, the second corresponding relation can also be stored by base station to facilitate its to determine,
Can certainly miscellaneous equipment stored, the determination function is realized in base station by being interacted with the equipment.If by base
Station is stored, then base station need to obtain relay station, the tracing area of relay station, reside in the terminal of the relay station jurisdiction district
Relevant information, in one embodiment, base station can be received on the relay station after relay station is moved to this base station jurisdiction district
The relay station identity of report and tracing area are identified；Then by the relay station identity for receiving and tracing area mark, note
Enter the second corresponding relation.
Second corresponding relation also can be by base station in location update request message relay station identity, relay station with
Track area identification, terminal identity mark are updated.In implementation, relay station identity can be added into institute by the relay station
State location update request message.
Certainly, the second corresponding relation can also be recorded in a mapping table or database, in order to inquire about.
Combine the paging method specific implementation of location updating method in explanation above-described embodiment as an example below.Fig. 5 is
The flow chart of paging method in this example；In this example, Relay_a is a fixed relay station, and UE_k is one and resides in Relay_a
Under terminal.Whole process still can be divided into three different phases.Flow shown in main description Fig. 5 flows with shown in Fig. 4 below
The difference of journey.
In the stage one, in step 501 to step 502, Relay_a can send a control message from trend eNB
Control_Message_1, the definition of this control message is identical with the Control_Message_1 in Fig. 4 with function.And figure
Unlike 4, in step 503a, the present internal maintenances of eNB be a tracing area, relay station and terminal mapping table
（TA-Relay-UE）, the mapping table the second corresponding relation of storage.After Control_Message_1 is received, eNB can be by
Mapping relations between Relay_a and other tracing area TA_a add this mapping table.The message in following stage one（Step
Rapid 503b）It is identical with process with Fig. 4.
In the stage two, in step 504, UE_k is moved in the cell of Relay_a, similar with Fig. 4, in step 505,
Relay_a broadcasts identity and the tracing area mark of oneself in the cell of oneself, and in step 506, UE_k is being received
After the broadcast message of Relay_a, control message Tracking_Area_Update_Request can be sent to Relay_a.With Fig. 4
Unlike, in step 507, Relay_a can be processed this message to generate control message Control_Message_
2.A Control_Message_2 parameters many relative to Tracking_Area_Update_Request, i.e. Relay_a's
Identity Relay_ID.In step 508-509, Relay_a sends Control_Message_2, and eNB is receiving Control_
After Message_2, can be according to the information pair included in message（TA-Relay-UE）Mapping table is updated, and thus eNB knows
UE_k is now resided in the cell of Relay_a.
In the stage three, in step 512, eNB can go inquiry after Paging message is connected to Fig. 4 similarly（TA-
Relay-UE）Mapping table, is concluded in the cell that UE_k now resides on Relay_a with this, therefore in step 513, eNB is straight
Connect and Paging message is sent to Relay_a, then perform step 514, Relay_a has started to UE_k in the cell of oneself
Paging.
In one embodiment, in order to reduce the change to relay station, the location update request message of terminal can be accessed
Domain message.Illustrate as an example below.Paging flow as shown in Figure 6, it is different only in the stage two compared with Fig. 5, therefore in Fig. 6
Omit stage one and stage three.
In figure 6, in step 601, UE_k is moved in the cell of Relay_a；In step 602, UE_k receives Relay_a
System message；And in step 603, the not oriented Relay_a of UE_k send message Tracking_Area_Update_
Request, but have sent a message Control_Message_3 for new definition.Because Tracking_Area_Update_
Request is a non-access domain message, therefore to allow that Relay_a processes this message, it is necessary to right in Figure 5
Relay_a carries out larger change.And newly-designed message Control_Message_3 is an access domain message in Fig. 6, therefore
Relay_a need not do too big change and can just process this message.It is similar with Tracking_Area_Update_Request,
Identity UE_ID and its tracing area comprising UE_k identify TA_a in Control_Message_3.Subsequent step 604-
606 is similar with Fig. 5.
