Description
Technical field
The present invention relates to multimedia broadcast multi-broadcasting business multimedia broadcast multi-broadcasting business (MBMS, Multimedia Broadcast Multicast Service) subscriber equipment (UE in system, User Equipment) business information reports technology, particularly relates to sending method and the system of a kind of receiving state report by user equipment in multimedia broadcast multicast service.
Background technology
In order to effectively utilize mobile network resource, third generation partner program (3GPP, 3rd Generation Partnership Project) propose MBMS, this MBMS is a kind of technology transmitting data from a data source to multiple destination mobile terminals, achieve sharing of network (including core net and access network) resource, improve the utilization rate of Internet resources especially air interface resource.
nullAt Long Term Evolution (LTE，Long Term Evolution) in system，Notifying user equipment (or claiming terminal) will change about certain MBMS，These changes can be session start (session start)、Service bearer updates or session stops (session stop) etc.，Can be first at Physical Downlink Control Channel (PDCCH，Physical Downlink Control Channel) on send Downlink Control Information (DCI，Downlink Control Information) and MBMS wireless network temporary sign symbol (M-RNTI，MBMS-Radio Network Temporary Identifier).UE goes to read concrete MCCH message according to the relevant information in DCI further, and this is referred to as MCCH notice (notification) mechanism.Concrete business configuration parameter will be sent on MCCH channel, such as traffic ID, the wireless spread-spectrum technology (RLC, Radio Link Control) of business, media interviews control (MAC, Media Access Control), physical layer configuration parameter etc..
In LTE system, MBMS has two kinds of bearing modes: broadcast mode and enhancement mode broadcast mode.Owing to not having multicasting mode, therefore network side can not be known UE reception/or prepare to receive which MBMS.Strengthen broadcast between broadcast with multicast, absorb that flow process in broadcast is simple and the advantage of resource optimization in multicast.When using MBMS to strengthen broadcast bearer, it is only necessary to just can realize the registration/cancellation from UE to BM-SC by addition/departure process on the application layer, it is not necessary to carry out Signalling exchange and information storage in bearer network network layers.Strengthening broadcast is that the one to broadcast optimizes and extension, as in access network, strengthens broadcast and will not receive the community transmission data of user to those.MBMS for enhancement mode, at configuration System Frame Number (SFN, System Frame Number) and need UE state and the quantity considering to receive MBMS during Resources allocation, the UE information thus needing reception/or preparation to receive MBMS is fed back, and this is referred to as the uplink feedback of MBMS.3GPP Rel10MBMS is for activation/deactivation MBSFN transmission means, and network side needs to obtain the receiving status information of UE, as received the UE quantity information of given MBMS, it is therefore desirable to a kind of mechanism reports the information of self reception state for triggering UE.
In order to enable network side to have the number of users of MBMS demand in obtaining each community, MBMS system introduces counting (counting) process.
Counting process refers to when MBMS Session starts, or during Session is carried out (also referred to as recounting), network side statistics receives and the process of reception MBMS number of users interested in community, in order to be confirmed whether employing MBSFN transmission means.When network side prepares to initiate the counting process of counting/again, the access information (access info) of MCCH adds the mark of MBMS and access probability.Access probability to be used, is because being not required to all of user and all sets up connection and feed back, as long as to be likely to be breached thresholding the most permissible for the quantity of feedback, otherwise free time (Idle) status user can cause uplink congestion when of more.
Summary of the invention
To in the research of prior art and practice process, inventor finds that prior art there is problems in that 3GPP Rel10MBMS needs to activate or the method for deexcitation MBSFN transmission means, the method is based on UE receiving state report, but prior art specification does not has a kind of method realizing UE transmission receiving state report, i.e. UE cannot know when send receiving status information and send which feedback information.
In order to realize UE is received the statistics of state, need to design a kind of UE and carry out the implementation method of uplink feedback.
In view of this, present invention is primarily targeted at the implementation method providing a kind of UE report multimedia BroadCast MultiCast Service to receive state, UE will receive state reporting network side according to described method, it is achieved the requirement of the MBSFN transmission means of network side activation or deexcitation MBMS.
