Said method of the present invention first receives MBMS statistical message by terminal, judge whether to participate in this MBMS statistic processes according to the MBMS information in MBMS statistical message, if participate in, then receive PF information, then judge whether to feed back to network side according to PF information; Such terminal is not when participating in this MBMS statistic processes, and just do not need to receive PF information, namely MBMS statistical message and PF information independently receive, and under determining to participate in the prerequisite of this MBMS statistic processes, then receives PF information in terminal; Make in LTE system, PF information can send, and terminal can participate in MBMS statistic processes, and reduces terminal for the reception of unnecessary information in statistic processes, thus saves the electric energy of terminal.
Wherein, above-mentioned steps 11 is specially:
Step 111, described terminal, from the MCCH message received by MCCH (multicast control channel), obtains described MBMS statistical message.
And in above-mentioned steps 12, described terminal according to the MBMS information in described MBMS statistical message, and is confirmed whether that participating in this MBMS statistic processes is specially:
Described terminal, according to the MBMS information in described MBMS statistical message, judges whether the MBMS receiving MBMS or will receive; If so, this MBMS statistic processes is then participated in.
In above-mentioned steps 12, the step that described terminal obtains access probability factor PF information in this MBMS statistic processes described from other message being different from described MBMS statistical message is specially:
Described terminal obtains the PF information of current statistic cycle transmission in this MBMS statistic processes from other message being different from described MBMS statistical message.

Preferably, described random number is the numerical value between 0 ~ 1.
As shown in Figure 2, be the specific implementation flow process of method shown in above-mentioned Fig. 1, this specific implementation flow process comprises:
Terminal receives the MBMS statistical message that network side sends, and resolves;
Terminal judges oneself the need of this statistic processes of participation (as oneself interested MBMS that terminal is receiving MBMS or will receive according to the MBMS information comprised in MBMS statistical message, then can determine to participate in this statistic processes, otherwise, do not participate in), if not, terminate this statistic processes, otherwise, enter next step;
Terminal receives MCCH or BCCH message, obtains the pre-assigned radio frames of PF information wherein and/or sub-frame information; It should be noted that: if above-mentioned UE does not receive MBMS statistical message, now, UE does not receive PF information yet, do not participate in MBMS feedback;
Terminal is according to these radio frames and/or subframe, and first the PF information in this MBMS statistic processes that obtains sends the PF information at cycle place and resolves; Wherein, as shown in Figure 3, this MBMS statistic processes comprises several measurement periods, and the beginning of each measurement period or end, send a PF information, the moment of this transmission PF information is called: PF information sends cycle place, namely the PF information that the first measurement period of this MBMS statistic processes starts or end sends is called: first PF information sends the PF information of cycle place's transmission, the PF information that second period starts or end sends is called: second PF information sends the PF information of cycle place's transmission, the like;
Terminal locates the PF information of transmission information cycle according to this first PF, judge oneself the need of feedback (as terminal generates a random number, if this random number is less than or equal to the numerical value that PF information represents, then terminal needs to feed back to network side, otherwise, can not feed back), if, then send and feed back to network side, otherwise, whether this MBMS statistic processes of terminal judges terminates, if, then terminate, otherwise, terminal receives the PF information that second PF information sends cycle place, and resolve, and then the PF information at cycle place is sent according to this second PF information, judge that oneself sends feedback message the need of to network side, the like, until this MBMS statistic processes terminates.
Said method of the present invention mainly through, UE (terminal) receive network side send MBMS statistical message (MBMS statistical message here does not comprise MBMS access probability factor, but comprise the MBMS information of network side needs statistics), UE judges whether according to MBMS information the MBMS statistic processes participating in the initiation of this network side, if need this UE to participate in, so UE receives PF information in this MBMS statistic processes (PF information is send in the cycle in a MBMS statistic processes, PF value each time may upgrade), and judge whether to participate in feedback according to PF information, otherwise this UE does not participate in this MBMS and adds up.
UE judges whether according to MBMS information the MBMS statistic processes participating in this network side, is specially:
If when this MBMS statistic processes is the MBMS for sending, UE judges whether oneself is receiving MBMS corresponding to MBMS information; If so, then this UE participates in this statistic processes; Otherwise UE does not participate in this statistic processes; Or,
UE judges whether according to MBMS information the MBMS statistic processes participating in this network side, is specially:
If when this MBMS statistic processes is the MBMS for not sending, UE judges the MBMS that whether interested oneself reception MBMS information be corresponding; If so, then this UE participates in this MBMS statistic processes; Otherwise UE does not participate in this MBMS statistic processes.
Further, if UE determines to participate in this MBMS statistic processes, so UE can determine according to the radio frames of the PF information sent in MCCH or BCCH and/or sub-frame information the subframe that PF information occurs, then UE starts the PF information that first the PF information received in this statistic processes sends cycle place's transmission, according to the PF information received, numerical value between UE stochastic generation one 0 ~ 1, by the numeric ratio corresponding with the PF information received comparatively, judge oneself whether to participate in first measurement period and send feedback information to network side, if UE determines to participate in feedback in first measurement period, after so UE feedback terminates, this UE then completes this MBMS statistic processes.If UE determines that no longer first interior participation of measurement period is fed back, so UE needs to continue the PF information that reception second PF information sends cycle place's transmission, determine whether oneself can participate in feedback by second measurement period more again, the like, until UE completes the feedback of oneself, or UE receives the order of this MBMS statistic processes of termination that network side sends.
Wherein, the object of PF information is for UE provides the numerical information of a percentage, the description form of this numerical value can be varied, example uses 30 to describe 30%, 0.1 is used to describe 10% etc., but be the numerical value will expressing a percentage eventually through calculating, the purposes of this numerical value be the numeric ratio that produces at random with UE comparatively, if the numerical value that UE produces is less than or equal to numerical value corresponding to this PF information, so this UE then needs to send feedback information to network side, otherwise UE receives next PF information, continue to repeat said process; If PF information spinner selects part UE to feed back in a measurement period, the resource anxiety that the UE quantity simultaneously fed back too much and to network side is brought can be avoided like this.
Network side can be: evolution base station (eNB), relay station (relay), cell cooperative entity (MCE, Multi-cell/multicast Coordination Entity), broadcast multicast service center (BMSC, Broadcast-Multicast-Service Centre), MBMS gateway (MBMS GW, MBMSGateWay) etc.

Suppose at a certain MBSFN (Multimedia Broadcast multicast service SingleFrequency Network, multimedia broadcast-multicast service Single Frequency Network) in region, network side initiates MBMS statistics for a certain MBMS sent, in LTE, also do not determine that MBMS statistical message (comprises the MBMS information of network side needs statistics in the statistical message in the present embodiment further at present, do not comprise PF information), the position how sending and send, the present embodiment hypothesis network side sends in MCCH.Suppose that a certain UE is receiving this MBMS, so when this UE receives the MBMS statistical message of network side transmission, this UE needs the MBMS determining oneself whether receiving the MBMS statistical message needs statistics that network side sends, if UE does not receive, so UE then stops this MBMS statistic processes of network side, if UE receives, so UE this MBMS statistic processes of then needing participation network side to initiate; In this case, UE continues to perform process below:
UE receives the PF information sent in this MBMS statistic processes, and UE needed the transmission position first determining PF information before reception PF information here, and particularly, UE can obtain the transmission positional information of PF information by MCCH or BCCH; Preferably, UE receives first PF information in this MBMS statistic processes and sends the PF information that the cycle locates transmission, then UE produces the numerical value between one 0 ~ 1 at random, and the numerical value corresponding with receiving PF information compares, if the numerical value that UE produces is less than or equal to numerical value corresponding to PF information that UE receives, so send the feedback information of oneself in the one-period of this UE then in this statistic processes to network side, afterwards, thus terminate this MBMS statistic processes of this UE.If the numerical value that UE produces is greater than numerical value corresponding to PF information that UE receives, the feedback information of oneself is so sent in first measurement period of this UE then not in this statistic processes to network side, UE judges whether this MBMS statistic processes terminates, if terminated, so UE terminates feedback, if do not terminated, the PF information that UE needs second PF information transmission cycle of continuing in this fed back statistics process of reception to locate to send, then UE continues the operation of above-mentioned first measurement period until UE completes the feedback of this MBMS statistic processes, or UE receives the order that network side stops this MBMS statistics.
Embodiment 2, the present embodiment describes network side and carries out statistics feedback for the MBMS not starting to send:
Suppose in a certain MBSFN region, network side initiates MBMS statistics for a certain MBMS not starting to send, in LTE, also do not determine that MBMS statistical message (comprises the MBMS information of network side needs statistics in the MBMS statistical message in the present embodiment further at present, do not comprise PF information), the position how sending and send, the present embodiment hypothesis network side sends in MCCH.Suppose that a certain UE is interested for this MBMS, the UE of being embodied in interested is here exactly this UE monitoring MCCH update notification message to wait for this MBMS start send.When this UE receives the MBMS statistical message of network side transmission, this UE needs the MBMS determining the MBMS statistical message needs statistics that oneself reception network side whether interested sends, the reception if UE loses interest in, this MBMS that so UE then stops network side adds up, if UE reception interested, so UE this MBMS statistic processes of then needing participation network side to initiate; In this case, UE continues to perform process below:
UE receives the PF information sent in this MBMS statistic processes.Here UE needed the transmission position first determining PF information before reception PF information; Particularly, UE can obtain the transmission positional information of PF information by MCCH or BCCH; Preferably, UE receives first PF information in this MBMS statistic processes and sends the PF information that the cycle locates transmission, then UE produces the numerical value between one 0 ~ 1 at random, and the numerical value corresponding with receiving PF information compares, if the numerical value that UE produces is less than or equal to numerical value corresponding to PF information that UE receives, the feedback information of oneself is so sent in first measurement period of this UE then in this statistic processes to network side, after this UE successfully feeds back, thus terminate this MBMS statistic processes of this UE.If the numerical value that UE produces is greater than numerical value corresponding to PF information that UE receives, the feedback information of oneself is so sent in first measurement period of this UE then not in this statistic processes to network side, the PF information that UE needs second PF information transmission cycle of continuing in this fed back statistics process of reception to locate to send, then UE continues the operation of above-mentioned first measurement period, until UE completes the feedback of this MBMS statistic processes, or UE receives the order that network side stops this MBMS statistics.
To sum up, said method of the present invention gives in LTE system, the transmit mechanism of PF information and corresponding UE participate in the process of MBMS fed back statistics, and in said method of the present invention, adopt the principle of MBMS statistical message and PF information individual reception, receive PF information again determine to participate in the prerequisite of feedback at UE under, compared with prior art, the present invention reduces UE and save the electric energy of UE for the reception of unnecessary information in statistic processes.
