At Long Term Evolution (LTE, LongTermEvolution) in system, MBMS uses multimedia broadcast-multicast service SFN (MBSFN, MultimediaBroadcastmulticastserviceSingleFrequencyNetwor k) mode to be transmitted.The content receiving state aspect about MBMS uplink feedback subscriber equipment (UE, UserEquipment) is currently discussed.Network side is initiated by network side for the statistic processes (being also counting process) of some MBMS, network side issues the message of a mark comprising the MBMS that needs are added up to UE simultaneously, after relevant UE receives this message, according to the MBMS mark comprised in message, judge that self the most receives, or, if the MBMS state comprised in message is the MBMS not sent, then need to judge whether reception interested.Last UE side forms corresponding response message (CountingReportmessage for the MBMS in message, the namely message of the MBMS state report of UE, unified appellation is there is presently no for this response message, present specification is referred to as MBMS state report, the MBMS being mainly used as receiving of this information or the information of the MBMS of reception interested to network side feedback UE).
Fig. 1 is the flow chart of existing uplink scheduling request (SR, SchedulingRequest), as it is shown in figure 1, existing up transmission mechanism is briefly described as follows:
Step 101, UE initiates up SR, and UE described in notice base station has upstream data to need to be transmitted.In this step, it is assumed that UE has the SR resource of self, and is in connection status (RRCconnected).
Step 102, after base station receives SR request, distributes ascending resource for this UE.Here ascending resource is the resource for reporting transmission buffering state (BSR, BufferStatusReport) for UE distribution, and this resource is smaller, is used only for UE and reports BSR.BSR is defined in TE agreement 36.321, is divided into two kinds, and a kind of is short BSR, and size is 8bits (1 byte), a kind of be long BSR size be 24bits (3 bytes).Therefore, in this step, the resource of base station distribution is smaller, as long as guaranteeing the BSR that transmission is long.
Step 103, sends BSR and reports to base station in the ascending resource that UE distributes in a step 102.BSR carries the size information that UE needs the upstream data of transmission；
Step 104, base station is according to the BSR of the UE received, in conjunction with the measurement result etc. of UE, the ascending resource being suitable for for UE distribution.
Step 103 and step 104 mainly realize carrying out the principle of ascending resource distribution according to UE demand, so can avoid the waste of ascending resource.
Step 105, UE sends upstream data to base station in the ascending resource that step 104 is distributed.
The flow process distributed from above-mentioned ascending resource is it can be seen that the process of UE request scheduling is more complicated, it is contemplated that the feature of MBMS state report, as quantity of information is smaller, and data volume typically immobilizes.Above-mentioned ascending resource allocation flow, is not appropriate for carrying out MBMS state report for UE and reports.

Detailed description of the invention
The basic thought of the present invention is, after base station receives the notice of UE transmission upstream data, it not directly to distribute BSR resource for UE by existing mode, and it is intended to first determine whether to be in MBMS counting process, it is to say, UE to be determined whether have sent MBMS Counting requests, and currently MBMS counting process is still had not yet to terminate, if having, then distribute longer BSR resource (i.e. the BSR resource of 24bits) for UE as far as possible；And when UE needs the upstream data sent just to be MBMS state report, the BSR resource using base station to be its distribution is sent MBMS state report by UE.
In the present invention, when UE is in connection status, and network side is its row control channel (PUCCH physically, PhysicalUplinkControlChannel) SR resource it is assigned with on, (it is really upper layer network element if network side has initiated a counting process here and initiates MBMS counting process, finally the order of correlated count process is sent associated base stations, by associated base stations, MBMS is counted order and be sent to UE), described UE needs to participate in MBMS counting process, i.e. needs the MBMS by currently received MBMS or interested to report network side.Concrete, UE sends SR solicited message to base station, after base station receives the SR solicited message of this UE, corresponding ascending resource is distributed to UE (here according to technical scheme for it, base station is in MBMS counting process, now, base station needs may use the ascending resource transmission MBMS state report of described distribution in view of UE.Certainly, if counting process terminates, then without the concern for), UE sends MBMS state report to base station in the ascending resource of distribution, base station is after receiving the upstream data of UE, and whether detection UE have sent MBMS state report to base station (because base station is in counting process, so needing to carry out the detection of MBMS state report, if counting process terminates, then base station need not perform this detection).
If what base station detected that UE sends is MBMS state report, then the SR request process that this UE initiates terminates.If that base station detects that UE sends is BSR, then it is that UE distributes ascending resource that base station then needs to refer to BSR content, and UE sends upstream data in described distribution ascending resource and receives the data of UE transmission to base station, base station.
In the present invention, described MBMS state report includes at least one of following information: mark UE is receiving or the information of MBMS of reception interested, the information in the MBSFN region that mark MBMS state report is corresponding, the information of the counting process that mark MBMS state report is corresponding.
For making the object, technical solutions and advantages of the present invention clearer, by the following examples and referring to the drawings, the present invention is described in more detail.
Embodiment one
Assume that some MBMS in a certain MBSFN region have been initiated MBMS counting process by network side, it is assumed here that by multiple cell/multicast coordination entity (MCE, Multi-cell/multicastCoordinationEntity) the counting order of the counting process that configuration is relevant, and counting order is sent to associated base stations, correlated count order is sent to UE by multicast control channel (MCCH, MulticastControlChannel) by base station.The moment or MBMS counting process initial time (as in the initial time of counting order instruction MBMS counting process) that send counting order can be denoted as a time starting point by base station, afterwards until this counting process terminates, base station is required for considering and MBMS state report relevant treatment.
After UE receives the counting order that base station sends, resolve command, and therefrom acquisition needs to carry out the information of the MBMS of feedback count.UE judges whether to need to carry out uplink feedback according to the information of described MBMS, i.e. gives base station the need of transmission MBMS state report, and the foundation needing exist for feedback is exactly that UE is receiving described MBMS or the MBMS of reception interested.This example assumes the feedback having UE to need now to participate in counting process, then the MBMS state report for this UE sends idiographic flow as shown in Figure 2, Fig. 2 is the flow chart that the present invention sends the embodiment one of MBMS state report, and the present invention sends MBMS state report and specifically includes following steps:
Step 201, in UE row control channel (PUCCH, PhysicalUplinkControlChannel) physically, in the SR resource of self, transmission SR information, to base station, shows that UE has upstream data to need to be transferred to base station.
Step 202, after base station receives the SR information of this UE, base station is that it distributes ascending resource.Owing to base station is in counting process, therefore base station is when the ascending resource carrying out this step distributes, need may use the ascending resource transmission MBMS state report of this sub-distribution in view of UE, so distribute the ascending resource meeting MBMS state report transmission as much as possible when distributing ascending resource size.In conjunction with existing protocol, it is contemplated that MBMS state report may exceed 8bits, therefore, in the present invention, base station first-selection is the BSR resource that UE distribution is longer, is the BSR resource of UE distribution 24bits, so that UE can utilize BSR resource transmission MBMS state report.Certainly, if longer BSR resource all can not carry the MBMS state report of UE, BSR resource can be extended, make base station provide the BSR resource that capacity is bigger.
Step 203, sends MBMS state report to base station in the ascending resource that UE distributes in step 202..
After base station receives the upstream data that in step 203, UE sends, base station needs to carry out following detection, and owing to base station is still in MBMS counting process, the upstream data that base station needs detection UE to utilize BSR resource to send is MBMS state report or BSR itself.If MBMS state report, base station has been received by the MBMS state report that UE sends, and base station can send, to UE, the information such as ACK information that relevant confirmation is properly received.This SR request process of this UE can also directly be terminated in base station.So far, the MBMS state report transfer process of the present invention terminates.
If base station detects that upstream data is BSR, then base station distributes ascending resource according to the measurement report etc. of BSR data and UE for UE.UE occurs UE to need the upstream data of transmission in the ascending resource that base station is its distribution.
In the present embodiment, the ascending resource in step 202 (BSR resource) is utilized to directly transmit MBMS state report, the data volume being primarily due to MBMS state report is smaller, and it is fixing for substantially keeping, the ascending resource that can distribute in step 202. completely carries, it is possible to directly utilize the ascending resource in step 202；And, whether base station performs to detect whether the upstream data that transmits in step 203 of UE is that MBMS state report has trigger condition, during i.e. base station must be in a certain MBMS counting process, just can perform the detection of MBMS state report, otherwise base station does not perform the detection of MBMS state report, correspondingly can also alleviate the burden that base station is unnecessary.The flow process that the present embodiment uploads MBMS state report is simple, decreases the interaction between UE and base station.
Embodiment two
The present embodiment carries out some on the basis of embodiment one and adjusts, and is primarily directed to how those UE not having SR resource in PUCCH send MBMS state report.
Assume that some MBMS in a certain MBSFN region are initiated MBMS counting process by network side, it is assumed here that the counting order of the counting process being correlated with by MCE configuration, and counting order is sent to associated base stations, correlated count order is sent to UE by MCCH by base station.The moment MBMS counting process initial time sending counting order can be denoted as a time starting point by base station, and afterwards until this counting process terminates, base station is required for considering and MBMS state report relevant treatment.
After UE receives the counting order that base station sends, resolve command, and therefrom acquisition needs to carry out the information of the MBMS of feedback count.UE judges whether to need to carry out uplink feedback according to the information of described MBMS, and i.e. to base station the need of transmission MBMS state report, the foundation needing exist for feedback is exactly that UE is receiving described MBMS or the described MBMS of reception interested.This example assumes the feedback having UE to need now to participate in counting process, then the MBMS state report for this UE sends idiographic flow as shown in Figure 3, Fig. 3 is the flow chart that the present invention sends the embodiment two of MBMS state report, and the present invention sends MBMS state report and specifically includes following steps:
Step 301, UE sends the RandomAccessPreamble of Stochastic accessing in Physical Random Access Channel (PRACH, PhysicalRandomAccessChannel), shows that UE self needs to carry out uplink random access.
Step 302, after base station receives leading (Preamble) code of this UE, base station is that the UE that this Preamble code is corresponding distributes ascending resource.Owing to base station is in counting process, therefore base station is when the ascending resource carrying out this step distributes, need may use the ascending resource transmission MBMS state report of this sub-distribution in view of UE, so distribute the ascending resource meeting MBMS state report transmission as far as possible when distributing ascending resource size.
Step 303, sends MBMS state report to base station in the ascending resource that UE distributes in step 302.
After base station receives the data that in step 303, UE sends, base station needs to carry out following detection, and owing to base station is in counting process, it is MBMS state report or BSR that base station needs to detect described data.If it is then base station has been received by the MBMS state report that UE sends, base station can send the information that relevant confirmation is properly received, such as ACK information to UE.Base station can also directly terminate this uplink random access request process of this UE.
In the present embodiment, UE utilizes the ascending resource in the 302nd step to directly transmit MBMS state report, the data volume being primarily due to MBMS state report is smaller, and it is fixing for substantially keeping, the ascending resource that can distribute in step 302 completely carries, so the ascending resource that can directly utilize in step 302, and, whether base station performs to detect whether the data transmitted in step 303 of UE are that MBMS state report has trigger condition, during i.e. base station must be in a certain MBMS counting process, just can perform the detection of MBMS state report, otherwise base station does not perform the detection of MBMS state report, the burden that base station is unnecessary can also be decreased accordingly.The flow process that the present embodiment sends MBMS state report is simple, decreases the interaction between UE and base station.
The present embodiment applies also for the UE of idle condition (RRC_IDLE) and sends MBMS state report.I.e. it is in the UE of RRC_IDLE when need to send MBMS state report, can be realized by aforesaid flow process (step 301 to step 303).
