Before this step, MS receives the system message SI13 of the base station broadcast of Serving cell, this system message SI13 comprises control message responding ability indication information, and whether the base station that this control message responding ability indication information is used to indicate Serving cell has the ability of system information in neighboring area request and the request of response system information in neighboring area of identification MS transmission; MS determines that according to control message responding ability indication information the base station of Serving cell has the ability of system information in neighboring area request and the request of response system information in neighboring area of identification MS transmission.
102, by PACCH channel, receive the response message to system information in neighboring area request that base station utilizes described TBF to send, this response message comprises: the system message of the corresponding adjacent area of sign of adjacent area, this system information in neighboring area comprises the parameter information of adjacent area.
Wherein, to the response message of system information in neighboring area request, can be grouping adjacent area data message PacketNeighbor Cell Data.Wherein, system information in neighboring area can be system message 3 or system message 4.
In the embodiment of the present invention, MS utilizes TBF to pass through the system message of PACCH channel to the base station requests adjacent area of Serving cell, and the system information in neighboring area that utilizes TBF to send by the base station of PACCH channel reception Serving cell, the loss that neither needs to hang up TBF and avoided data block, also can not increase the burden of network side and MS.
Consult Fig. 2, the embodiment of the present invention provides a kind of system information in neighboring area sending method, and the method comprises:
201, by PACCH channel, receive the system information in neighboring area request that MS utilizes TBF to send, this system information in neighboring area request comprises: the sign of adjacent area and the sign of described TBF.Wherein, the sign of TBF can be the will of temporarily failing to be sold at auction (Temporary Flow Identity, TFI) of TBF; System information in neighboring area request can be packet neighbor sound zone system message request Packet NCell SI Request.
Wherein, the executive agent of the each step of this embodiment can be the base station of the Serving cell at MS place.
Wherein, the sign of adjacent area can comprise: index and new BSIC corresponding to adjacent area of adjacent area in BA table, or, ARFCN and BSIC.
Before this step, the system message SI13 of the base station broadcast of Serving cell, this system message SI13 comprises control message responding ability indication information, whether the base station that wherein, control message responding ability indication information is used to indicate Serving cell has the system information in neighboring area request that identification MS sends and the ability that responds this system information in neighboring area request.MS determines that according to the control message responding ability indication information in this system message SI13 the base station of Serving cell has the system information in neighboring area request of identifying MS transmission and the ability that responds this system information in neighboring area request, then utilize the TBF that set up to the base station of Serving cell, to send system information in neighboring area request by PACCH channel, and in system information in neighboring area request, carry the sign of adjacent area and transmit the sign of the TBF of this system information in neighboring area request.
202, according to the sign of TBF, by TBF described in PACCH channel usage, to MS, send the response message to system information in neighboring area request, this response message comprises: the system message of the corresponding adjacent area of sign of adjacent area, this system information in neighboring area comprises the parameter information of adjacent area.
Wherein, to the response message of system information in neighboring area request, can be grouping adjacent area data message PacketNeighbor Cell Data.Wherein, the system message of the corresponding adjacent area of sign of adjacent area is system message 3 or system message 4.
If the sign of adjacent area comprises: index and BSIC corresponding to adjacent area of adjacent area in BA table.Before this step, the base station of Serving cell is the index in BA table according to adjacent area, determine the corresponding BSIC in adjacent area that index identifies, then judge that whether the BSIC in the sign of the adjacent area that determined BSIC and MS send is identical, if so, execution step 202, if not, determine that packet neighbor sound zone system message request is wrong, do not send response message, subsequent step is also no longer carried out.
If the sign of adjacent area comprises: ARFCN and BSIC, the base station of Serving cell determines according to ARFCN and BSIC MS asks the system message of which adjacent area.
