S206 is to SA enabling counting flow process.At first, the access probability factor that reads the backstage configuration upgrades gap periods (ApfUptInterval), idle (Idle) pattern N access probability factor (APF) corresponding respectively with being connected (Connected) pattern.Wherein, the access probability that APF is corresponding increases progressively by certain density, and the access probability of N access period (Accessperiod) is 1, and variable i=1 is set, and reads the professional P thresholding of this MBMS simultaneously.
S208 adopts i group APF to count, and obtains the UE number (CountNumber) that expectation in the coverage receives this MBMS business according to counting response and MBMS UEService Context according to the method statistic of particular count scheme.
S210 is if CountNumber greater than the P*CellNumber thresholding, then selects the P-T-M mode to send.If CountNumber is smaller or equal to the P*CellNumber thresholding, then i=i+1 upgrades gap periods then at APF, repeated execution of steps S206, S208 and S210.
S212, (be about to N APF and traveled through, i＞N), CountNumber equals 0, does not then send (not setting up MBMS RB) if the count cycle finishes.
S214; Professional in step S202, S204 and S210, being judged as the MBMS that adopts the P-T-M mode to send; In selected sub-district, set up RB according to following cell selecting standard: the professional RB of MBMS is set up as a set in the adjacent area of selecting sub-district that all UE distribute and these sub-districts thereof; If it is professional that the MBMS business is the S class, then in selected sub-district, apply for new Secondary Common Control Physical Channel (S-CCPCH), if success application, then the RB of selected sub-district sets up successfully; If it is professional that the MBMS business is the I/B class; Then in selected sub-district; Judge at first whether this MBMS business can be multiplexed on the professional S-CCPCH of other MBMS, if can be multiplexing, then with current MBMS service integration to other S-CCPCH; If can not be multiplexing, then in selected sub-district, apply for new S-CCPCH.
That is to say; The RNC counting only needs statistics MBMS UE Service Context to get final product; When the UE initiation of URA_PCH, CELL_PCH or CELL_FACH attitude is counted, need make marks to already present MBMS UE Service Context, if having no counting response; Think that then the MBMS UE Service Context that mark is crossed correctly receives, not very within the UE number range that expectation receives.And count results greater than 0 situation under, in the coverage, select proper cell to set up the professional radio bearer (RB) of MBMS; Equal in count results not set up the professional radio bearer of MBMS under 0 the situation.Wherein, select the method for sub-district to be: also not exist expectation to receive the professional UE of MBMS in the district if current area is expected to receive the professional UE of MBMS and faced, then do not set up the professional RB of MBMS.
In sum, the invention provides a kind of method of setting up the professional radio bearer of P-T-MMBMS according to SA level count results.Adopt the present invention; Can select suitable cell to set up the professional radio bearer of MBMS according to the UE count results of coverage; The saving finite wireless resources had both been considered in the system of selection of sub-district, had considered the characteristics that move at the terminal that reception is served in the mobile communication again.
