In existing statistic processes, because network side need determine to adopt point-to-point (PTP, Point To Point) pattern to send the MBMS business according to the quantity of subscribing to UE, or adopt point-to-multipoint (PTM, Point To Multi-point) pattern to send the MBMS business.Therefore, network side need obtain the UE quantity of a certain MBMS business of definite subscription, thereby causes the UE of each response " statistics " all to need to connect with network, thereby causes a series of problem.
And in the present invention, network side only adopts the PTM pattern to send the MBMS business, and based on these characteristics, network side no longer needs to carry out the selection of sending mode according to the quantity of subscribing to UE when subscribing to the UE statistics.Therefore, network side also just no longer needs to obtain the UE quantity of a certain MBMS business of definite subscription, and only need know whether exist the UE that subscribes to a certain MBMS business to get final product.In this case, the result of statistics can be summed up as " having " and " nothing ", and the result of statistics can adopt Boolean quantity to indicate.
The present invention proposes the detection method of user's existence in a kind of MBMS business according to the demand of above-mentioned network side to statistics.Below, 1 pair of this method is done and is specified in conjunction with the embodiments.
In the method, for implementing the transmission of MBMS business, network side still needs to regularly publish the MBMS service statement, provides which MBMS business so that UE is known network side.UE still subscribes to corresponding M BMS service groups after receiving the MBMS service statement of network side issue according to demand, and obtains corresponding M BMS Group ID, professional relevant decoding key, and carries out relevant authentication and charging process.
Network side is initiated statistic processes by MICH, knows the subscription UE that whether has a certain MBMS business, and statistic processes comprises the steps: as shown in Figure 2
In step 201, network side is initiated paging by MICH to UE.Network side carries the MBMS Group ID of MBMS business to be initiated by MICH, carries MBMS business change information-statistics by the associated MCCH of MICH, and UE response " statistics " needed ascending resource configuration parameter.
Wherein,, can indicate UE to adopt the power of configuration to send response message, also can indicate UE to adopt the power of acquiescence to send response message by the ascending resource configuration parameter.
When network side indication transmitted power, the UE of response " statistics " will adopt described ascending resource to send response message to network side by described transmitted power; Network side can receive the response message that UE sends by described ascending resource.
In step 202, UE demodulation MICH obtains MBMS Group ID, knows which kind of MBMS business network side will initiate.
In step 203, whether the MBMS Group ID that UE inquires about its acquisition is the MBMS Group ID of its subscription.
When the MBMS Group ID of UE demodulation MICH acquisition was not the MBMS GroupID of its subscription, in step 204, UE did not respond this paging.
When the MBMS Group ID of UE demodulation MICH acquisition is the MBMS Group ID of its subscription, in step 205, UE will continue the associated MCCH of demodulation MICH, obtain MBMS business change information-statistics, and the ascending resource configuration parameter of network side distribution.
In step 206, UE will adopt the ascending resource of network side configuration to send the response message of " statistics " to network side.
In step 207, network side receives response message and the demodulation reference symbol wherein that UE sends.
Owing in the TD-SCDMA system, adopt OFDM (OFDM) mode transmission signals, and OFDM is the physical-layer techniques of LTE system, inserts all uniformly-spaced, equably in row and the downlink data " reference symbol (reference symbol) " thereon.Reference symbol is used for the estimation of channel, detection of channel quality or the like purposes, and relevant reference symbol more detailed description is referring to TR25.814.
Described reference symbol both can be the reference signal of interpolation between data, also can be " statistics " dedicated reference symbol that pre-sets.
In step 208, network side adopts the standard symbol that presets that reference symbol is carried out related calculation, and obtains the power of reference symbol.
In step 209, network side compares the power of reference symbol with the threshold value of presetting, determine whether there is the UE that subscribes to described MBMS business in the respective cell, finish statistic processes according to comparative result.
When the power of reference symbol is less than or equal to described threshold value, there is not the UE that subscribes to described MBMS business in the respective cell;
When the power of reference symbol during, there is the UE that subscribes to described MBMS business in the respective cell greater than described threshold value.
Wherein, described threshold value can obtain by simulation calculation, also can be according to the actual conditions setting.
After network side is determined whether to have the UE that subscribes to described MBMS business in the respective cell, export the result to SFN Area dynamic management functional entity, carry out suitable SFN territory adjustment for it.
