Description
Technical field
The present invention relates to multimedia broadcast-multicast service (Multimedia Broadcast and MulticastServices is called for short MBMS) field, particularly relate to a kind of multimedia broadcast multicast service statistical information sending method and system.
Background technology
At Long Term Evolution (Long Term Evolution, be called for short LTE) in system, MBMS adopts multimedia broadcast-multicast service single frequency network (Multimedia Broadcast multicast service SingleFrequencyNetwork, being called for short MBSFN) mode sends, MBSFN mode is the mode that a kind of multi-plot joint sends: the multiple communities in a region are in the identical time, frequency resource sends identical MBMS data signal, these are in MBSFN mode, community composition MBSFN region (MBSFN area) of harmonious transmission business, like this, in MBSFN region, identical wireless signal corresponding to the data sent from each community superposes naturally, thus significantly improve the intensity of user terminal Received signal strength.
The pass of MBSFN area and community is: a MBSFN area comprises one or more community.A community can belong to one or more MBSFN area.In one cell, a MBSFNarea MBSFN area ID identifies.
To each MBSFN area, community configures one or more PMCH (Physical multicastchannel physical layer broadcast channel), for carrying control information and the business datum of this MBSFN area for it.Wherein, control information, comprises channel configuration and service configuration information is carried on logic channel MCCH (Multicast Control Channel, multicast control channel).MCCH channel bearing at transmission channel MCH (Multicast Channel, Multicast Channel), and then is carried on Physical Multicast Channel PMCH.Each MBSFN area its special MCCH channel corresponding and the MCCH message carried on it.
The transmission of MCCH message relates to two cycles, and one is the amendment cycle, and it wherein revises periodic packets containing one or more repetition period two for transmission cycle or the repetition period of being called.In the time-frequency domain resources of specifying within each repetition period, the MCCH message described in network side sends.Described MCCH message its content within an amendment cycle remains unchanged, and the MBMS message content that is sent in its repetition period comprised is identical.
In the prior art, above-mentioned MCCH message at least comprises: the mark of the MBMS of carrying, the mapping relations of MBMS and MCH channel, Logic Channel Identifier (the LCID that MBMS is corresponding, Logical Channel ID), the resource allocation information of PMCH channel and MCH channel, and the map information of business and described channel.
The bearing mode of MBMS is as follows: a MBMS is carried on a logic channel MTCH, one or more MTCH is carried on a transmission channel MCH, and the different MTCH Logic Channel Identifiers (LCID) being carried on identical MCH channel are distinguished.A MCH channel bearing is at a physical channel PMCH.
Consider that MBMS broadcasting service is the broadcast for MBSFN region, improve the angle of resource efficiency from operator, there is the demand needing the reception condition of adding up a specific MBMS in MBSFN region.That is, operator needs to know at special time, whether has user and is receiving certain specific MBMS.Like this, network side can according to the situation in a community or a MBSFN district intra domain user reception MBMS, determine whether to continue to send this MBMS in this community or MBSFN region, or send this MBMS (clean culture or multicast) in which way.If do not have user to receive, network can stop or temporarily stopping at wave point sending this business, to improve the service efficiency of Radio Resource.
Above-mentioned align afoot MBMS stop at wave point send method, be called deexcitation, corresponding process is called deactivation process.Send at wave point the business recovery of deactivation status, be called activation, corresponding process is called activation.
In the prior art, the network element that above-mentioned counting and activation/deactivation process relate to and method are described below:
As shown in Figure 1, access network element multiple cell multicast coordination entity (Multi-cell/multicastCoordination Entity is called for short MCE) indicates certain specific MBMS to need counting by chain of command message flow triggering access network unit base station (eNB) in the MCCH message of its community.Here, network element centered by MCE, plays and coordinates and control the synchronous finishing service data transmission of each eNB and the function such as resource distribution, the renewal of MCCH channel.
Listen to the subscriber equipment (UE can be described as terminal again) of above-mentioned MCCH message, the state according to it is in:
If be in RRC connected state (RRC Connected, RRC:Radio Resource Control, radio resource control), and receiving or wishing to receive this business, then this UE sends chain of command message instruction eNB.
If be in RRC connected state, but do not receive or do not wish to receive this business, then not responding the counting indicator of this business.
If be in RRC Idle state (RRC IDLE), no matter whether receive or wish to receive, not responding the counting indicator of this business.
The number of the UE that the hope counted in a period of time receives or receiving this business is reported to MCE network element as statistics by above-mentioned eNB.After MCE network element gathers the statistics of the eNB in the MBSFNarea sending this business, whether decision-making is in wireless interface activation or this business of deexcitation, or adopts which kind of mode to send this business.
Above-mentioned a period of time, for the eNB in the MBSFN area at the affiliated MBMS place of MCE appointment is in its community, the time that synchronous carrying out is added up.This time period is also referred to as timing statistics section or gate time section (Counting Interval).
It should be noted that, for keeping the transmission condition of MBSFN, the activation of MCE decision-making or deactivating operation are carried out within the scope of MBSFN area, and that is, all communities in MBSFN area, activate or the specific business of deexcitation simultaneously.Same reason is keep the MBSFN of MCCH message to send condition, MCE to coordinate in MBSFN area all communities on corresponding MCCH synchronized update to the counting indicator information of specific transactions.
In the methods described above, no matter be in the state of its reception business of UE of RRC Idle state, all can not initiate RRC and connect to feed back its accepting state.Although said method realizes simple, avoid the UE triggering RRC being in RRC Idle state in a large number and connect the radio interface congestion brought.But find in actual application, because only added up the reception service conditions of the UE being in connected state in above-mentioned technology, and do not consider the reception service conditions of the UE being in Idle state, so the number of the UE of the reception business only obtained according to this statistics will far fewer than the UE of all reception business.MCE may not improve resource efficiency, but reduce resource efficiency on the contrary make the decision-making carrying out clean culture transmission according to this statistics after.

The count results of above-mentioned one or more base station feedback adds up by MCE respectively, obtains the total number M0 of UE counted in the region of above-mentioned one or more base station subordinate multiple communities composition, and total number M1 of counting radix UE.
Step 5, MCE network element calculates the quantity being in the UE receiving described MBMS in the UE of RRC Idle state;
Particularly, according to receiving in ratio N/M and the predetermined RRC of being in Idle state UE or wishing that the UE ratio receiving this MBMS and the scale factor being in RRC connected state UE the UE ratio receiving or wishes to receive this MBMS calculate the ratio of the UE receiving described MBMS in the UE being in RRC Idle state, then the total quantity calculating that basis is in the UE of RRC Idle state determines to be in the quantity receiving the UE of described MBMS in the UE of RRC Idle state;
Step 6, calculates the sum of UE receiving described MBMS, namely receives the quantity sum receiving the UE of this MBMS in the quantity of the UE of this MBMS and RRC connected state UE in RRC Idle state UE.
Due to calculated be in Idle state UE in receive the quantity of this MBMS, therefore, the statistical information that MCE obtains is more comprehensively objective, and carrying out decision-making with reference to this statistical information can obtain better effect.
According to the difference of counting radix UE definition, the computational methods slightly difference of MCE, is described below respectively:
● if counting radix UE is defined as and belongs to capability class three and the UE being in RRC connected state, then:
MCE calculates according to M0 and M1 and belongs to capability class three and the ratio R0=M0/M1 being in the UE of RRC connected state the UE receiving this MBMS (or claim to have fed back accepting state, and receiving this business).
MCE calculates according to R0 and is in RRC Idle state and belongs in the UE of capability class three, is receiving the ratio of the UE of described MBMS.Concrete, if be in RRC Idle state and belong to capability class three and UE (user) ratio receiving this business be in RRC connected state and belong to capability class three and the scale factor receiving UE (user) ratio of this business is k (k > 0), this scale factor k be can be empirical value or is obtained by statistics or obtain by inquiry, MCE can be extrapolated by k*R0 and is in RRC Idle state and belongs to capability class three and receive the ratio of the UE of this MBMS, again according to being in RRC Idle state and the quantity belonging to the UE of capability class three calculates and is in RRC Idle state and belongs to capability class three and receive the quantity of the UE of this MBMS:
Be in RRC Idle state and belong to capability class three and receive quantity=(S-M1) * k* (M0/M1) of the UE of this MBMS
Wherein, S is the sum of the UE belonging to capability class three in MBSFN region, and S-M1 is the quantity belonging to capability class three in MBSFN region and be in the UE of Idle state.
MCE calculates and belongs to capability class three and sum=(S-M1) * k* (the M0/M1)+M1 receiving the UE of described MBMS.
When adopting this kind of method to calculate, after calculating and receiving the quantity of the UE of this MBMS in all UE belonging to capability class three, according to belong to capability class two and the UE quantity receiving this MBMS with belong to capability class three and receive the scale factor x2 of the UE quantity of this MBMS, calculate the quantity receiving the UE of this MBMS in all UE belonging to capability class two.And then statistics more accurately can be obtained.
● if counting radix UE is defined as: belong to capability class one and be in RRC connected state UE, belong to capability class two and be in the UE of RRC connected state and belong to capability class three and be in the UE of RRC connected state, then:
MCE calculates at all RRC of being in connected states according to M0 and M1 and belongs to the ratio R0=M0/M1 of the UE receiving this MBMS in the UE of capability class three.
Then MCE can obtain according to the scale factor k preset: under being in RRC Idle state, belonging to capability class three and receiving the ratio k*R0 that this MBMS UE quantity accounts for all Idle state UE quantity.Can calculate to obtain according to this ratio and be in RRC Idle state and belong to capability class three and receive the quantity of the UE of this MBMS, finally calculate and belong to capability class three and the sum receiving the UE of described MBMS.
This method is applicable to the accepting state that operator does not need the UE of consideration ability two, the situation of the UE of a statistical power type three.
Now, base station only needs the RRC of being in connected state UE all in above-mentioned community to be all calculated as the UE of counting radix, and does not need the capability class judging described UE according to the version of UE or ability information instruction, realizes more simple.
Application Example one
In the present embodiment, counting radix UE is defined as and belongs to capability class three and the UE being in RRC connected state.Present embodiment describes the statistics how utilizing counting radix, realize calculating the accepting state of the UE being in RRC Idle state, and to belonging to the calculating of accepting state of UE of capability class two (namely not possessing MBMS counting feedback function).
The version information that base station reports according to UE or the ability information that UE reports, can know the ability classification being in RRC connected state UE, and simply can add up and obtain one or more community and to fall into a trap the number N1 of base number UE.The UE quantity N0 of counting that base station will be obtained by counting process in one or more community, and the quantity N1 of counting radix UE sends to MCE network element.N0 and N1 can be the statistics according to community, or the accumulation result of described multiple Cell statistical result.
MCE adds up the count results of one or more base station: carry out the cumulative quantity M0 obtaining the counting UE of one or more base station to the quantity N0 of the counting UE that each base station reports; The cumulative quantity M1 obtaining one or more base station inside counting radix UE is carried out to the quantity N1 of the counting radix UE that each base station reports.
MCE calculates ratio R0=M0/M1, wherein/and be the division sign.This ratio R0 represents the ratio that the quantity of UE carrying out counting feedback accounts for the quantity of counting radix UE, namely belongs to ability classification three and is in the ratio of the UE receiving described MBMS in the UE of RRC connected state.
Scale factor k according to pre-setting can extrapolate, and is in the UE of RRC Idle state, is receiving this MBMS and the ratio belonging to the UE of capability class three is k*R0.
Can MBMS be received due to the UE in capability class two but can not feed back, if so want to know in capability class two have how many UE to receive MBMS, also calculated by above-mentioned R0.Determine to belong to capability class two by investigation or statistics and be in the UE ratio that receives this MBMS in the UE of connected state and belong to capability class three and be in the scale factor x1 (x1 > 0) of the U ratio E receiving this MBMS in the UE of connected state, and belong to capability class two and be in the UE ratio that receives this MBMS in the UE of Idle state and belong to capability class three and be in the scale factor x1 ' (x1 ' > 0) of the UE ratio receiving this MBMS in the UE of Idle state.Can determine thus to belong to capability class two and the ratio being in the UE receiving this MBMS in the UE of RRC connected state is x1*R0, belong to capability class two and the ratio being in the UE receiving this MBMS in the UE of RRC Idle state is x1 ' * k*R0.
