In embodiments of the present invention, the ability letter of the ability information of described first community and first community adjacent cell Cease for assisting terminal when there being uplink service, select the one or more first objects to coupling business demand Cell sends the first service request, and wherein, described first service request includes：Business demand grade, industry Business carries required speed, time delay value, bit error rate requirement, service disconnection probability demands, and service quality One or more of supportability information information.Wherein, described first object cell be first community and/ Or one or more first community adjacent cell.
For terminal how according to the ability information of first community and the ability information choosing of first community adjacent cell Select first object cell send the first service request, preceding method description in aforementioned in be described in detail, It is not discussed here.In this embodiment, main description is when the first industry having cell cannot carry terminal Processing method during business request, as described below：
When one or more of first object cells cannot carry the first service request of terminal, the first mesh Mark cell sends service request refuse information to terminal, so that terminal is redefined and sends the of the first service request Three Target cells (i.e. new target cell).Wherein, described service request refuse information includes recommending terminal weight The cell identity information of the new one or more cells sending the first service request, wherein, described cell ID Information includes：Cell IP address, subdistrict frequency point, cell address, for service request be successfully established in advance One or more of the physical resource position of distribution and Cell Radio Network Temporary Identifier/Identity, Cell-RNTI information information.
When one or more first object cells cannot carry the first service request of terminal, at utmost Ensure Consumer's Experience it is impossible to carry terminal traffic request first object cell can service request refuse letter The cell identity information of the one or more cells recommending terminal to resend the first service request is carried in breath. Terminal reselects Target cell the (i.e. the 3rd according to being included in cell identity information in service request refuse information Target cell) send the first service request.
Further, when described first object cell cannot carry the first service request of terminal, described One Target cell can carry the cell identity information of the cell of the first service request to network side feedback, wherein, Described cell identity information includes：Cell IP address, subdistrict frequency point, cell address, build for service request Stand successfully one of the pre-assigned physical resource position of institute and Cell Radio Network Temporary Identifier/Identity, Cell-RNTI information Or much information.
When described first object cell cannot carry the first service request of terminal, the second Target cell can be by The cell identity information that the cell of terminal first service request can be carried feeds back to core net, is determined by core net The Serving cell of terminal, makes core net and terminal directly enter row information by the Serving cell that core net determines and hands over Mutually, meanwhile, the cell identity information that can carry the cell of terminal first service request is sent out by first object cell Deliver to terminal, make terminal monitor the schedule information of these cells at any time.
Wherein, it is understood that there may be multiple situations make first object cell cannot carry the service request of terminal：
(1) ability information of the cell being obtained due to terminal is user all towards full cell, exists little The ability that region layer face obtains can meet the service request of terminal, but because cell will be multiple terminal clothes simultaneously Business, in order to ensure that other terminals can service, and refuses the situation of the service request of single terminal.
(2) because terminal receives broadcast message moment Target cell to terminal traffic request delivery time Load occur large change, lead to terminal send service request moment Target cell cannot meet terminal Service request.
It should be noted that agreeing to terminal first service request when having in one or more first object cells During cell, this cell can send service request to terminal and receive message, and terminal can be from the first object agreed to One cell of assessed value highest is selected as the cell sending service request in cell, and simultaneously, if having or not The first object cell of method carrying terminal first service request sends to terminal to carry recommends terminal again to send out Send the first service request the cell identity information of one or more cells when, terminal can to this cell send industry Business request revocation message, thus refuse this cell.
In embodiments of the present invention, when described first object cell cannot carry the first service request of terminal, Except above-mentioned terminal reselects transmission the first industry by the cell identity information in service request refuse information It is impossible to the first object cell carrying terminal traffic request can be by outside the method for business request the 3rd Target cell The terminal being in Idle state redirects to the 3rd Target cell that can carry the first service request or will be in The terminal of connected state switches to the 3rd Target cell that can carry the first service request.
Wherein it is impossible to the one or more first object cells carrying terminal first service request can pass through base station The adjacent cell of interface and this first object cell carries out information exchange, finds and determines and can meet the of terminal 3rd Target cell of one service request.
Cannot carry terminal traffic request first object cell can by inter-base station interface (such as X2 interface, X2 interface propagation delay time is far below the cycle of broadcast information updating, with more real-time) carry out with adjacent cell Information exchange, finds and determines the cell that can meet terminal traffic request carrying, and fast in this cell for terminal Fast initiating business request provides required information and resource, the physics money as needed for terminal originating service request (Cell Radio Network Temporary Identifier/Identity, Cell-RNTI is believed for source position, the coded system being used or random sequences, C-RNTI Breath) etc..
Further, the described one or more first object cells that cannot carry terminal first service request can Information exchange is carried out by the adjacent cell of inter-base station interface and this first object cell, specially：
1) the first object cell that cannot carry the first service request of terminal passes through inter-base station interface by terminal The first service request in business demand information be sent to the adjacent cell of first object cell, make this first mesh The adjacent cell of mark cell is compared with self-ability according to the business demand information in the first service request, sentences Break and whether can carry the first service request；If can carry, send to first object cell and confirm feedback, no Then send refusal feedback.
Wherein, in the first described service request, business demand information includes：Business demand grade, business are held Carry required speed, time delay value, bit error rate requirement, service disconnection probability demands, and service quality guarantee One or more of ability information information.
2) the first object cell that cannot carry the first service request of terminal receives the confirmation of multiple adjacent cells During feedback, select one or more cells as the 3rd Target cell.
First object cell for further understanding the first service request that cannot carry terminal is led to adjacent cell Cross the process that inter-base station interface (here) communicates taking X2 interface as a example, be exemplified below, as Fig. 7 institute Show：
S801, cannot carry terminal traffic request cell pass through that X2 interface sends to adjacent cell whether can be by Terminal traffic request is redirected to the message of this adjacent cell, or whether this adjacent cell can meet terminal thereon The message of initiating business request.
S802, adjacent cell judge whether after receiving the solicited message of cell that cannot carry terminal traffic request The service request of terminal can be met.
S803, adjacent cell send to the cell that cannot carry terminal traffic request and redirect request or service request Feedback information, if can meet including adjacent cell, sends request to the cell that cannot carry terminal traffic request Confirm message, otherwise send service request refuse information.
S804, cannot carry terminal traffic request cell receive multiple adjacent cells request feedback information,
S805, the cell that cannot carry terminal traffic request obtain one or more adjacent cell receivabilities and redirect Request or can meet terminal traffic request after, to adjacent cell send auxiliary terminal redirect or quickly initiate business The resource request information of request, such as the physical resource position needed for terminal originating service request, is adopted Access sequence, C-RNTI etc..
S806, cannot carry terminal traffic request cell redirect the terminal to one or more receivability weights The adjacent cell of orientation request, or will can meet the information of one or more adjacent cells of terminal traffic request in industry Terminal is informed in business request refusal information.
In sum, when the first service request having cell cannot carry terminal, terminal can be according to cannot hold The service request refuse information that the cell of mounted terminal first service request sends selects new Target cell again Send the first service request, or the cell of terminal first service request cannot be carried by carrying out with adjacent cell Information exchange, terminal is redirected or switches to the cell meeting business demand.
