Flow process can be learnt as shown in Figure 2, base station is current by clear and definite terminal is to reside in the community of oneself, or in the community of jurisdiction relay station, can carry out paging targetedly, compared with the technical scheme of base station in prior art and the equal call terminal of jurisdiction relay station, obviously optimize the paging of junction network, reduced the signaling consumption of system paging, saved the paging resource of system.
During due to a certain terminal of network side paging, MME can find all base stations that are associated with these TA according to the current TA list of this terminal, and beep-page message is sent to these base stations, and the TA list of terminal to be MME safeguard according to the positional information of terminal report, therefore, in one embodiment, before described base station receives described beep-page message, can also comprise:
Described base station forwards the location update request message of described terminal, and when described terminal resides in jurisdiction district, described base station, in described location update request message, tracing area mark is the tracing area mark of described base station; When described terminal resides in described relay station jurisdiction district, in described location update request message, tracing area mark is the tracing area mark of described relay station.
In base station, the location update request message of terminal is transmitted to after MME, MME just can be according to the tracing area mark of carrying in this location update request message, the more tracking zone list of new terminal.In the time of MME issuing page message, can the identify label of carried terminal and the tracking zone list of terminal in beep-page message.
Mention above, if terminal resides in relay station jurisdiction district, in the location update request message of terminal, can carry the tracing area mark of relay station.And because location update request message is to be generated and sent by terminal, be forwarded to MME through relay station, base station again, therefore, the mode of carrying the tracing area mark of relay station in the update request message of real present position can have multiple, for example: the tracing area of described relay station mark is to be obtained from described relay station by described terminal, and be added into described location update request message; And for example, the tracing area of described relay station mark is added into described location update request message by described relay station; For another example, the tracing area of described relay station mark is to be obtained from described relay station by described base station, and is added into described location update request message.
In an embodiment, terminal obtains the tracing area mark of relay station from relay station, Ke Yishi: terminal, in the time entering relay station jurisdiction district, receives the relay station tracing area mark of relay station broadcast.Can see, in prior art, terminal is in the time entering relay station jurisdiction district, and what relay station was broadcasted is the tracing area mark of base station, and in the present embodiment, terminal is in the time entering relay station jurisdiction district, and what relay station was broadcasted is the tracing area mark of relay station.In prior art, due to the movement of relay station, the tracing area of the base station of relay station broadcast identifies in continuous variation, and terminal is by continuous launch position update request; And in the present embodiment, even if relay station is moving, it is also geostationary that the relay station of relay station broadcast is followed the tracks of mark, the frequency of terminal launch position update request reduces greatly, has effectively reduced position and has upgraded the signaling traffic load bringing.
As shown in Figure 3, the present invention can also provide a kind of location updating method, and its flow process can comprise:
Flow process shown in Fig. 3 the receives relay station broadcast tracing area mark of base station while entering jurisdiction district from terminal in prior art is different, can effectively reduce the great amount of terminals of bringing due to the movement of relay station and carry out frequently the signaling traffic load that position renewal brings simultaneously.
Location updating method shown in Fig. 3 can use separately, also can be combined with the paging method shown in Fig. 2, in the time being combined with, has optimized on the one hand the paging of junction network, has reduced the waste of paging resource in junction network; Also prevented that on the other hand adding of mobile-relay station, the overweight problem of signaling traffic load was upgraded in caused position.
Determine that in order to facilitate base station in beep-page message, tracing area mark is tracing area mark or the tracing area of this base station jurisdiction relay station mark of this base station, in one embodiment, the first corresponding relation can be determined in base station, and according to the first corresponding relation, determine that in described beep-page message, tracing area mark is tracing area mark or the tracing area of this base station jurisdiction relay station mark of this base station; Wherein, the first corresponding relation is the corresponding relation between the tracing area of this base station jurisdiction relay station, this relay station.
The first corresponding relation can store to facilitate it to determine by base station, and can certainly be stored by miscellaneous equipment, base station is by carrying out determining function to realize this alternately with this equipment.If stored by base station, base station need obtain the relevant information of the tracing area of relay station, relay station, in one embodiment, base station can move to behind this jurisdiction district, base station at relay station, receives relay station identify label and tracing area mark that this relay station reports; Then by the relay station identify label receiving and tracing area mark, charge to the first corresponding relation.
The first corresponding relation can be recorded in a mapping table or database, so that inquiry.
Lifting the paging method that combines location updating method in an example explanation above-described embodiment below specifically implements.Fig. 4 is the flow chart of paging method in this example; In this example, relay station Relay_c is the relay station of a movement, and terminal UE _ i is the terminal under this mobile-relay station, and for completing the paging to terminal UE _ i, whole flow process can be divided into three phases, comprising:
Stage one
Step 403a-b, eNB storage inside the mapping table of tracing area and relay station corresponding relation: (TA-Relay) mapping table, this mapping table is stored the first corresponding relation.ENB is receiving after Control_Message_1, first can upgrade (TA-Relay) mapping table according to information wherein, then eNB can send a control message on S1-MME interface to MME, for example ENB_CONFIGURATION_UPDATE, comprises the identify label eNB_ID of eNB and the tracing area of Relay_c mark TA_c in this control message.After receiving this control message, just can learn MME that present Relay_c resides in this eNB community.
Stage two
Step 405, Relay_c broadcast identify label Relay_ID and the tracing area mark TA_c of oneself in the community of oneself by system message.
Just can be to the Relay_c Tracking_Area_Update_Request(location update request message that transmits control message after the system message of step 406, UE_i Relay_c broadcast after receiving) with launch position renewal process.Tracking_Area_Update_Request has definition in existing standard, wherein comprises identify label UE_ID and the tracing area mark TA_c of terminal.
Step 407, Relay_c do not process receiving after this message, but are directly transmitted to eNB.
Step 408, eNB do not process receiving after this message, but directly by its forwarding until MME.
Step 409, MME are the list that each UE has safeguarded a tracing area.MME is receiving the tracking zone list TA_List_of_UE_i that TA_c can be added to UE_i after the Tracking_Area_Update_Request that UE_i sends.Here, in Fig. 3, the response message Tracking_Area_Update_Response of all-network side to Tracking_Area_Update_Request, is omitted in the drawings.
Stage three
Step 410, MME receive the paging request of core net to UE_i.
Step 412, eNB are receiving after this Paging message, can remove inquiry (TA-Relay) mapping table according to the tracing area mark of listing in TA_List_of_UE_i.
Step 413, because in TA_List_of_UE_i there is a strong possibility only includes TA_c, and the tracing area that does not comprise other relay station below eNB and eNB identifies, so eNB can only send to Relay_c so that it starts the paging to UE_i this Paging message, and not be used in paging UE_i in oneself community, also need not allow own other relay station below carry out paging UE_i.
Mention above, the first corresponding relation is the corresponding relation between the tracing area of this base station jurisdiction relay station, this relay station, in another embodiment, the second corresponding relation also can be determined in base station, and according to the second corresponding relation, determine that in described beep-page message, tracing area mark is tracing area mark or the tracing area of this base station jurisdiction relay station mark of this base station; Wherein, the second corresponding relation be this base station jurisdiction relay station, this relay station tracing area, reside in the corresponding relation between the terminal of this relay station jurisdiction district.
Certainly, similar with the first corresponding relation, the second corresponding relation also can store to facilitate it to determine by base station, and can certainly store by miscellaneous equipment, base station is by carrying out determining function to realize this alternately with this equipment.If stored by base station, base station need obtain relay station, relay station tracing area, reside in the relevant information of the terminal of this relay station jurisdiction district, in one embodiment, base station can move to behind this jurisdiction district, base station at relay station, receives relay station identify label and tracing area mark that this relay station reports; Then by the relay station identify label receiving and tracing area mark, charge to the second corresponding relation.
The second corresponding relation also can be upgraded according to the relay station identify label in location update request message, relay station tracing area mark, terminal identity mark by base station.In enforcement, relay station identify label can be added into described location update request message by described relay station.
Certainly, the second corresponding relation also can be recorded in a mapping table or database, so that inquiry.
Lifting the paging method that combines location updating method in an example explanation above-described embodiment below specifically implements.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 a terminal residing under Relay_a.Whole process still can be divided into three different phases.The difference of flow process shown in flow process shown in Fig. 5 and Fig. 4 is mainly described below.
In the stage one, step 501 is to step 502, and Relay_a can send a control message Control_Message_1 from trend eNB, and the definition of this control message is identical with the Control_Message_1 in Fig. 4 with function.Different with Fig. 4, in step 503a, the present internal maintenance of eNB be a tracing area, the mapping table (TA-Relay-UE) of relay station and terminal, this mapping table is stored the second corresponding relation.Receiving after Control_Message_1, eNB can add this mapping table by the mapping relations between Relay_a and other tracing area TA_a.Next the message in stage one (step 503b) is identical with Fig. 4 with process.
In the stage two, in step 504, UE_k moves in the community of Relay_a, similar with Fig. 4, in step 505, Relay_a broadcasts identify label and the tracing area mark of oneself in the community of oneself, in step 506, UE_k is receiving after the broadcast of Relay_a, can be to the Relay_a Tracking_Area_Update_Request that transmits control message.Different from Fig. 4, in step 507, Relay_a can process to generate control message Control_Message_2 to this message.Control_Message_2 with respect to Tracking_Area_Update_Request many a parameter, i.e. the identify label Relay_ID of Relay_a.At step 508-509, Relay_a sends Control_Message_2, eNB is receiving after Control_Message_2, can upgrade (TA-Relay-UE) mapping table according to the information comprising in message, and eNB has known that UE_k resides in the community of Relay_a now thus.
In the stage three, with Fig. 4 be similarly, in step 512, eNB can remove inquiry (TA-Relay-UE) mapping table receiving after Paging message, conclude that with this UE_k resides in the community of Relay_a now, therefore, in step 513, eNB directly sends to Relay_a by Paging message, perform step subsequently 514, Relay_a and in the community of oneself, started the paging to UE_k.
In an embodiment, in order to reduce the change to relay station, the location update request message of terminal can be input field message.Lift an example explanation below.Paging flow process as shown in Figure 6, compared with Fig. 5, different only in the stage two, therefore in Fig. 6, omit stage one and stage three.
In Fig. 6, in step 601, UE_k moves in the community 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, but send a new message Control_Message_3 who defines.Because Tracking_Area_Update_Request is a non-access domain message, therefore in Fig. 5, to make Relay_a can process this message, need to carry out larger change to Relay_a.And newly-designed message Control_Message_3 is an input field message in Fig. 6, therefore Relay_a just can process this message without doing too large change.Similar with Tracking_Area_Update_Request, the identify label UE_ID and its tracing area that in Control_Message_3, comprise UE_k identify TA_a.Subsequent step 604-606 and Fig. 5 are similar.
