Area, the configuration of above-mentioned cell parameter refer specifically to configure the configuration of parameter related with neighboring BS relationship, and for new cell other with
The unrelated parameter configuration of neighboring BS relationship can use implementation in the prior art, and details are not described herein again.
Optionally, step 101 be specifically as follows the affiliated mobile base station of new cell within a preset time continuously receive letter
Number, primary synchronization signal (Primary Synchronization Signal, the abbreviation of each adjacent cell are searched in the signal
PSS) and secondary synchronization signal (Secondary Synchronizaiton Signal, abbreviation SSS), according to each adjacent cell
Primary synchronization signal and secondary synchronization signal determine each adjacent area of the new cell and the physical-layer cell identifier of the adjacent area.
Specifically, LTE (Long term evolation, abbreviation LTE) communication system has 504 physical-layer cell marks
Know.Physical-layer cell identifier and PSS/SSS are corresponded.The cell each having built up is required in the fixation position of radio frames
Send PSS and SSS corresponding with the physical-layer cell identifier of the cell.The new affiliated mobile base station of cell connects within a preset time
The continued access collection of letters number, searches for PSS and SSS in the received signal, determines adjacent area number and each neighbour by the PSS and SSS that search
The physical-layer cell identifier in area.Wherein, which can carry out flexible setting according to demand, for example, it is pre- that this can be set
If the time is greater than 10ms.
Optionally, the mapping relations of the physical-layer cell identifier and parameter combination mark specifically:
IDcellModN=IDPara (1)
Wherein, IDcellIndicate physical-layer cell identifier, IDParaExpression parameter combination mark, mod are complementation, and N is ginseng
Array closes mark total number.
It should be noted that the mapping relations can also use other mapping relations, herein not in this, as limitation.
Optionally, there is no the case where adjacent area for new cell, the new affiliated mobile base station of cell carries out the new cell
Adjacent area search, determine that the new cell does not have adjacent area, then the affiliated mobile base station of new cell is in physical-layer cell identifier collection
Physical-layer cell identifier of the optional mark as the new cell in conjunction；According to the physical-layer cell identifier and parameter combination
The mapping relations of mark obtain parameter combination mark corresponding with the physical-layer cell identifier of the new cell, by the parameter group
The parameter combination that mark is closed as the new cell identifies；Wherein, the object is stored in the affiliated mobile base station of new cell
Layer cell identifiers set is managed, the physical-layer cell identifier set includes each physical-layer cell identifier.It is small to get the physical layer
Parameter configuration is completed using step 103 after area's mark and parameter combination mark.
Further, the specific acquisition modes of parameter combination logo collection are that the new affiliated mobile base station of cell is preparatory
Multiple parameters related with neighboring BS relationship in cell parameter are obtained, different valued combinations are carried out to each parameter and obtain each parameter group,
And corresponding parameter combination mark is distributed for each parameter group, generate the parameter combination logo collection.
The present embodiment, the adjacent area search by carrying out new cell determine the physical-layer cell identifier of each adjacent area of new cell,
It is obtained according to the mapping relations that physical-layer cell identifier and parameter combination identify corresponding with the physical-layer cell identifier of each adjacent area
Parameter combination mark, chooses one in parameter combination logo collection and identifies different mark conducts from the parameter combination of each adjacent area
The parameter combination of the new cell identifies, and the physical-layer cell identifier of the new cell is obtained further according to the mapping relations, new using this
The physical-layer cell identifier and parameter combination of cell identify corresponding parameter group and carry out cell parameter configuration to new cell, thus real
Base station can be automatically performed cell parameter configuration when now setting up new cell, without manually being carried out according to the neighboring BS relationship of each cell
Cell parameter configuration, during a large amount of Emergency communication vehicle networkings, the base station in each Emergency communication vehicle can be rapidly completed automatically
The parameter configuration of the cell of required foundation, and then can satisfy the requirement of emergency communication.
