Embodiment 1
Present embodiment is that example describes with the LTE system, and in the LTE system architecture, base station 1 links to each other with core net by the S1 interface respectively as target BS as source base station, base station 2, and UE resides in 1 jurisdiction district 1, base station.Not setting up X2 interface between base station 1 and the base station 2 is connected.
Sometime, UE initiates urgency traffic, in sub-district 1, initiate to insert at random request, and set up Radio Resource and control (RRC, Radio Resource Control) connects, since be urgency traffic, UE carries urgency traffic in sending to the RRC connection request of base station (RRC Connection Request) message indication.After RRC connected foundation, network side was set up the E-RAB of urgency traffic so that UE can accept the center communication with urgency communication for UE again.
Network side also send to be measured configuration to UE, and UE carries out and measures and report the Serving cell that satisfies report condition or the measurement report of neighbor cell.The a certain moment, signal quality neighbor cell (be sub-district 2 in the present embodiment, belong to base station 2) is good according to the signal quality of the measurement report discovery Serving cell 1 of UE is bad in base station 1, and then the urgency traffics switching is initiated to base station 2 in base station 1, detailed process comprises the steps: as shown in Figure 2
Step 201: base station 1 sends switching demand signaling (Handover Required) to core net, comprises the contextual information of Target cell (being sub-district 2) sign and this UE in this signaling;
Step 202: core net is received above-mentioned switching demand signaling, sends handoff request signaling (Handover Request) to base station 2;
Step 203: above-mentioned handoff request is received in base station 2, what know foundation according to the context of this UE is urgency traffic, yet because base station 2 Target cell of the having jurisdiction over 2 current urgency traffics of not supporting, therefore handoff failure signaling (Handover Failure) is returned to core net in base station 2, carry the urgency traffic ability information of Target cell 2 in this handoff failure signaling, promptly the urgency traffic ability information of Target cell 2 is not for possessing urgency traffic ability (promptly not supporting urgency traffic or be called not allow urgency traffic to switch);
In the present embodiment, failure cause is carried in base station 2 in the handoff failure signaling be that Target cell is not supported urgency traffic (perhaps not allowing urgency traffic to switch), represents that promptly Target cell 2 does not possess the urgency traffic ability;
Step 204: core net is received above-mentioned handoff failure signaling, therefrom read failure cause, send switching to base station 1 and prepare failed signaling (Handover Preparation Failure), and in this signaling, carry the failure cause that is read, promptly Target cell is not supported urgency traffic or is not allowed urgency traffic to switch;
Step 205: base station 1 receives that above-mentioned switching prepares failed signaling, preserves the information that Target cell in this signaling is not supported urgency traffic, no longer for this subscriber equipment to target BS (being base station 2) linchpin do not support the sub-district transmission handoff request of urgency traffic.
If there is other subscriber equipment also to set up urgency traffic, base station 1 has also no longer sent handoff request for these subscriber equipmenies of setting up urgency traffic to the sub-district of not supporting urgency traffic that target BS is had jurisdiction over.In preferred scheme, consider that the sub-district of not supporting urgency traffic might change the sub-district of supporting urgency traffic into, therefore, base station 1 is updated periodically the information whether Serving cell of being preserved supports urgency traffic, promptly only (timer can be set in a period of time, as 24 hours) preserve the cell information do not support urgency traffic, work as timer expiry, this part information of preserving will be deleted in base station 1, at this moment, base station 1 can send handoff request to sub-district 2 once more for the UE that sets up urgency traffic.
In other application scenarioss, when existing X2 interface to connect between base station 1 and the base station 2, base station 1 also can directly send handoff request by X2 interface to base station 2,2 of base stations can be returned the urgency traffic ability information that carries Target cell to base station 1 by X2 interface and (promptly whether support urgency traffic, also can be called and whether not allow urgency traffic to switch), wherein, when Target cell does not possess urgency traffic ability (promptly not supporting urgency traffic not allow urgency traffic to switch in other words), base station 2 can send to base station 1 and carry failure cause for not supporting urgency traffic, failed signaling is prepared in the switching that does not perhaps allow urgency traffic to switch, and base station 1 receives that the operation behind this switching preparation failed signaling is identical with above-mentioned steps 203.
Present embodiment can be applied among the WCDMA equally, at this moment, source RNC sends re-positioning request (Relocation Request) by core net or Iur interface to Target RNC, if Target cell is not supported urgency traffic, Target RNC then returns reorientation by core net or Iur interface to source RNC and prepares failed signaling, and the failure cause that carries in this signaling is that Target cell is not supported urgency traffic (perhaps be called and do not allow urgency traffic to switch).After receiving, takes source RNC and top described identical processing operation.
Embodiment 2
Present embodiment is that example describes with the LTE system still, but the present embodiment difference from Example 1 is, exists X2 interface to connect between 1 base station 2, base station.
Sometime, base station 1 sends X2 interface by X2 interface to base station 2 and sets up demand signalling (X2Setup Request), this X2 sets up the information (Served Cell Information) that has comprised Serving cell (being sub-district 1 in the present embodiment) in the demand signalling, the information of Serving cell comprises the sign of sub-district 1, Tracking Area Code (Tracking Area Code, abbreviate TAC as), public land mobile radio communication (PLMN, be used for the carrier network of the current use of identifying user), frequency, bandwidth, the urgency traffic ability information of frame format information and Serving cell (promptly whether support the information of urgency traffic, be also referred to as the information that whether allows urgency traffic to switch).In the present embodiment, the extend information of sub-district 1 is to have urgency traffic ability (promptly support urgency traffic, be also referred to as and allow the urgency traffic switching).
After base station 2 receives that above-mentioned X2 interface is set up request, preserve the information of sub-district 1 and (especially will preserve the urgency traffic ability information (information of promptly whether supporting the information of urgency traffic or whether allowing urgency traffic to switch) of sub-district 1 in the present embodiment, simultaneously, base station 2 is returned X2 interface to base station 1 and is set up response signaling (X2 Setup Response), the information that comprises the Serving cell of being had jurisdiction over base station 2 (comprising sub-district 2 and sub-district 3 herein) in this response signaling, wherein, the information of Serving cell comprises the urgency traffic ability information of Serving cell, and promptly whether Serving cell supports urgency traffic (being also referred to as the information that whether allows urgency traffic to switch).In the present embodiment, sub-district 2 has urgency traffic ability (promptly support urgency traffic or claim to allow urgency traffic to switch); Sub-district 3 has urgency traffic ability (promptly do not support urgency traffic or claim not allow urgency traffic to switch).
After this response signaling is received in base station 1, preserve the information (the especially urgency traffic ability information of Serving cell) of Serving cell wherein.Spent a period of time, urgency traffic has been set up in the calling of UE 1 initiation urgency traffic in the sub-district.Base station 1 is the configuration of UE allocating and measuring, and UE implements to measure according to measuring configuration, and reports the Serving cell that satisfies report condition or the measurement report of neighbor cell.Base station 1 is bad according to the signal quality that measurement report discovery UE records sub-district 1, and the signal quality of sub-district 2 and sub-district 3 is all above predetermined threshold, because base station 1 knows that sub-district 2 has the urgency traffic ability from the information of the Serving cell preserved, sub-district 3 does not have the urgency traffic ability, therefore, base station 1 selects sub-district 2 as the Target cell that switches, and do not select sub-district 3 as the Target cell that switches, at this moment, base station 1 also sends handoff request by X2 interface to base station 2, implements normal switching flow.
In other application scenarioss, can also transmit the urgency traffic ability information of Serving cell that this base station is had jurisdiction between base station 1 and the base station 2 by base station configuration updating signaling (ENB Configuration Update), and after reciprocity base station receives the config update signaling, preserve the information of Serving cell in this signaling, and be applied to set up in the Target cell selection of urgency traffic UE switching.
Also have in the application scenes, undertaken when mutual by X2 interface signaling or config update signaling between base station 1 and the base station 2, can also the information (Neighbour Information) and the urgency traffic ability information (being whether Serving cell is supported urgency traffic or whether supported the information that urgency traffic switches) of the neighbor cell of Serving cell that this base station is had jurisdiction over be sent to reciprocity base station by X2 interface signaling or config update signaling, after X2 interface signaling or config update signaling are received in the equity base station, preserve the information of Serving cell in this signaling, and be applied to set up in the Target cell selection of urgency traffic UE switching.
Embodiment 3
The application scenarios of present embodiment is identical with the application scenarios of embodiment 2.
Sometime, UE initiates urgency traffic, in sub-district 1, initiate to insert at random request, and set up Radio Resource and control (RRC, Radio Resource Control) connects, since be urgency traffic, UE carries urgency traffic in sending to the RRC connection request of base station (RRC Connection Request) message indication.After RRC connected foundation, UE sent Non-Access Stratum (NAS, Non Access Stratum) signaling (being service request (service request) signaling) by the base station to core net, to establish a communications link with core-network side.After the MME of network side receives the service request of UE transmission, MME sends initial context and sets up request (Initial Context Setup Request) message to base station 1, carries the cell information or the area information of the urgency traffic ability information (promptly whether supporting urgency traffic or be called whether allow urgency traffic to switch) of Serving cell in this " Initial Context Setup Request " message.MME can know that UE is a urgency traffic according to service request, know the urgency traffic ability information of the neighbor cell of sub-district 1 simultaneously according to network topology, like this, MME just can set up the urgency traffic ability information of carrying the neighbor cell of sub-district 1 in the request at initial context.Particularly, initial context is set up the cell information (also can be to carry the area information that one or more permission urgency traffics switch or do not allow urgency traffic to switch) that can carry one or more supports in the request or not support urgency traffic, to the LTE system, can be TAC (Tracking Area Code) and/or PLMN sign; To the WCDMA system, can be LAC (Location Area Code) and/or PLMN sign.
In a preferred embodiment, initial context is set up and can also be carried the system information of supporting urgency traffic or not supporting urgency traffic in the request, as carries the GERAN system information of not supporting urgency traffic.Need to prove, present initial context is set up in the request and is carried restricted area (HandoverRestriction List) information, but restricted area information is only applicable to non-emergent business, therefore, the present invention has expanded this part information, makes it also can be applied to urgency traffic.
