Embodiment
The present invention, in conjunction with the feature of LTE system, proposes concrete configuration mode in the configuration of PF information.
Because MBMS carries out carrying transmission in MBSFN mode in LTE, and in the process of LTE standard, advise activation or the closedown by carrying out MBMS in units of MBSFN region.This just needs the reception condition of all UE considered in whole MBSFN region, and such MBMS statistic processes should be initiated in units of MBSFN region, carries out the fed back statistics of reception situation in MBSFN region for a certain MBMS.
The present invention proposes to configure respective PF information for each MBSFN region or MCCH, and PF information here can be all PF information shared by the MBMS of adding up; Further PF information can be carried in MCCH and send to UE.The principal benefits done like this is easy to realize exactly, and operation is very simple, and whole MBMS statistic processes is simplified.Time delay when avoiding the respective PF information of each base station separate configurations is excessive, and the measurement period time is increased, and can effectively reduce the probability of makeing mistakes base station, promote statistical efficiency after unified configuration PF information.
Owing to there is relation one to one between MCCH and MBSFN region in LTE, so its actual MBSFN region represented corresponding to this MCCH of MCCH.
For each MBSFN region or MCCH configure a shared PF information, add up in a MBSFN region so in other words in a MBMS process, allly used identical PF information by the MBMS of adding up, described PF information can change at each PF place's information cycle in this MBMS measurement period.Now, allly identical PF information is shared by the MBMS of adding up when carrying out MBMS statistics in a MBSFN region or MCCH.And PF information sends to UE in MCCH.
In MBMS statistic processes, as shown in Figure 1, PF information repeatedly sends in a measurement period, such as, after network side starts MBMS statistics, to issue statistical information and be designated as starting point 0 second, continue 10 seconds, so MBMS measurement period is 10 seconds always.Period, network side needed repeatedly to send PF information, such as sent a shared PF information 0 second moment, this PF information is applied in whole MBSFN region or MCCH by the MBMS of adding up, the 2s moment sends a shared PF information again, 4s sends a shared PF information again ..., namely the cycle of PF information is 2 seconds, and ordinary circumstance PF increases information cycle successively.If network side, within the cycle of first shared PF information, has namely obtained the feedback information of needs in 2s, so network side can stop this MBMS statistics, then follow-uply in this cycle no longer send PF information.
Network side is when initiating MBMS statistics, first needing to be distinguished (namely network side determines the MBSFN region of each needs belonging to the MBMS of adding up) according to MBSFN region by the MBMS of adding up, and be allly in each MBSFN region configured a shared PF information by the MBMS of adding up.Upper layer node MCE (the Multi-cell/multicast Coordination Entity of PF information from base station here, multiple cell coordination entity) be configured, because MCE is the upper layer node be connected with all base stations in MBSFN region, MCE sends to each base station in MBSFN region PF information, and base station sends to UE again this information.This avoid the complex process that each base station is each community separate configurations PF information, parameter configuration in the statistics of MBMS is simplified.In a word, the maximum advantage of above-mentioned processing mode is exactly that network side process is simple, is easy to management, and the MBMS being particularly applicable to () is on a large scale added up in whole the MBSFN region in.Network side determines each MBSFN region belonging to the MBMS of adding up, and network side can be MCE or BMSC (Broadcast-Multicast-Service Centre, multimedia broadcast-multicast service center) here.
The configuration mode of another kind of PF information, network side is when initiating MBMS statistics, first network side determines the MBSFN region of each needs belonging to the MBMS of adding up, and all needs in each MBSFN region are divided into groups by the MBMS of adding up, in described MBSFN region, is configured a shared PF information for each group is all by the MBMS of adding up.Such as, in a MBSFN region, MBMS identical or close for multiple type can be divided into one group, for this group MBMS configures a shared PF information, described identical type of service comprises: streaming media service, TV business, downloading business and stock consulting class business.According to the MBMS classification of type provided in 3GPP normal structure, can be specially further: download class MBMS (File downloadservices), Streaming Media class MBMS (Streaming services), Carousel class MBMS and TV class MBMS (Television (TV) service).MBMS different like this can be divided into one group according to respective type of service, and for MBMS described in same group configures a shared PF information, the described MBMS of different service types can configure PF information different separately.Here mainly consider the dispatching cycle of dissimilar MBMS, business continuance requires, business is different at the acceptance rate of UE side, MBMS identical or close for feature is divided into one group, come more to be applicable to PF information for its configuration according to the specific features of the MBMS of each group, fed back statistics process can be made to carry out smoothly, the configuration accuracy rate of PF information is promoted, thus shortens measurement period.
Describe another way of the present invention more below, on the basis of the above, the mode of grouping has some to change, and as the state according to MBMS is divided into groups, such as, in LTE, current MBMS state is divided into 3 kinds: the MBMS that network side is sending; Network side is about to the MBMS sent; Network side has sent the MBMS of end.Here a kind of MBMS state is increased, this kind of state is: send before network side, but after network side is added up for such MBMS, find UE accepting state poor (not having the UE quantity of UE reception or reception not reach the threshold value of requirement), and by the MBMS that network side is closed, herein, be called the MBMS suspended and send.Business under these 4 kinds of states, network side needs to carry out the correlation circumstance statistics of UE side in order to realize different demands.Here according to the present invention, can according to one or more in above-mentioned state as criteria for classification, can be the shared PF information of above-mentioned each MBMS state assignment one.
In same MBSFN region or in MCCH, for all sending by the MBMS of adding up, network side, for it arranges a shared PF information in described MBSFN region, adds up the reception situation of UE side; In like manner, for all be about to send by the MBMS of adding up, network side is that it arranges the situation that a shared PF information adds up the UE reception interested when described MBMS sends in described MBSFN region; Equally, for all send terminate by the MBMS of adding up, network side is that it arranges a shared PF information to add up the UE satisfaction situation of this business during sending in described MBSFN region.Network side can add up the reason obtaining UE and do not carry out receiving for the MBMS suspended.Wherein various states can be selected to configure PF information according to specific requirement during concrete enforcement or each self-configuring PF information is added up simultaneously, if such as do not need to add up for sending the MBMS terminated, so the present invention is then divided into groups by the MBMS that sending and the MBMS that is about to send.
The main purpose of the MBMS statistics sent finds that there is not have UE to receive, and claimed accuracy is very low, and measurement period is shorter, such as several times of milliseconds.The initial configuration of such PF information needs larger, and within the first time PF cycle, just participate in feedback to ensure UE, increase progressively amplitude also larger, such as skipping a grade increases progressively.Mainly realize satisfaction investigation for the MBMS terminating to send, measurement period is long, and such as tens minutes, claimed accuracy was very high, and the rank of whole statistics is lower, only has and just adds up when Internet resources are idle.The initial value of such PF information arranges smaller, and the amplitude that increases progressively also is smaller, such as, increase progressively step by step, why is because PF information value is larger like this, means that resource occupying is larger.For the MBMS being about to send, if the time long enough of the time point that distance sends, can the initial value of PF information arrange smaller, increase progressively also smaller, such as, increase progressively step by step, carried out statistics, if the time that distance starts to send is shorter, so need the initial value of PF information arrange smaller, increase progressively larger, such as skipping a grade increases progressively.Suspend send MBMS, network side can add up its unwelcome reason, and measurement period is larger, can the initial value of PF information setting smaller, increase progressively also smaller, such as, increase progressively step by step, carried out statistics.
