The method comprises the following steps that: a network side sends request information for requesting user equipment (UE) to report MBMS receiving state information to the UE; and the UE reports the MBMS receiving state information to the network side after receiving the request information. The invention also provides the UE and the network side for realizing the MBMS continuity. According to the method, the network side actively requests the UE to report the MBMS receiving state information, the UE reports the information according to the network side requests, the MBMS service receiving state information can be taken as the reference during the network side switching, and the MBMS receiving continuity of the UE is ensured.
Description
Technical field
The present invention relates to Long Term Evolution (Long Term Evolution; LTE) technology; Be meant a kind of realization multimedia broadcast multi-broadcasting business (Multimedia Broadcast Multicast Service, MBMS) successional report method, subscriber equipment and network side especially.
Background technology
Along with the fast development of Internet (internet) and popularizing of large-screen Multi-featured Mobile Terminal; A large amount of mobile data multimedia services and various high bandwidth multimedia service have appearred; Like video conference, television broadcasting, video request program, advertisement, online education, interactive game etc.; This has satisfied the multiple services demand of mobile subscriber on the one hand, has also brought new business growth point for mobile operator simultaneously.These mobile data multimedia services require a plurality of users can receive identical data simultaneously, compare with general data service, have characteristics such as data volume is big, longer duration, delay sensitive.
In order to effectively utilize mobile network resource; Third generation partner program (3rd GenerationPartnership Project; 3GPP) proposed multimedia broadcast multi-broadcasting business (Multimedia BroadcastMulticast Service, MBMS), this business is a kind of technology that transmits data from a data source to a plurality of destination mobile terminals; Realize sharing of network (comprising core net and Access Network) resource, improved the utilance of Internet resources (especially air interface resource).The MBMS business of 3GPP definition not only can realize the classes of messages multicast and the broadcasting of plain text low rate; But also can realize broadcasting and the multicast that high-speed multimedia is professional; Multiple rich video, audio frequency and multimedia service are provided; This has complied with following mobile data Development Trend undoubtedly, for the development of 3G provides better professional prospect.
According to prior art; Receive the professional subscriber equipment of MBMS (UE, or title terminal) and can be in one of two states, a kind of is RRC (Radio Resources Control; Radio Resource control) connected state (RRC_CONNECTED; Abbreviate connected state as), another kind is RRC Idle state (RRC_IDLE abbreviates Idle state as).Whether set up RRC according to UE and link, can judge that UE is in connected state or is in Idle state with network side.Concrete, when having set up RRC with network side, UE links, and then UE is in connected state; Otherwise UE does not set up RRC with network side and links, and then UE is in Idle state.In the prior art, be in the UE of connected state, network side (for example: context etc.) will keep a series of configuration of this UE and parameter; And for the UE that is in Idle state, network side has then kept the less relatively information of this UE, and particular content is prior art, repeats no more here.
In the moving process of UE, use cell selecting or gravity treatment flow process to realize for the mobility of Idle state UE, and use the sub-district switching flow to realize for the mobility of connected state UE.The handoff procedure of UE is undertaken by UE auxiliary network side; In other words, network side (for example: source eNB (Node B of evolution)) in switch decision and Target cell selection course, play leading role; And the relevant informations such as measurement report that UE reports are as the reference of source eNB when doing switch decision.
When not introducing the MBMS business, source eNB does not consider that fully the selection of switch decision and Target cell receives the influence of MBMS business continuance for UE when carrying out switch decision; After introducing the MBMS business, need to consider this factor, be implemented in switching as far as possible after, UE still can guarantee the reception that MBMS is professional, just MBMS business continuance at Target cell; In existing scheme, the following method of general employing realizes:
When UE is in RRC_Connected, utilize prior art HO (HandOver switches) process, adopt UE to report mode, inform the professional accepting state of its MBMS of eNB; Generally speaking, the professional receiving status information of MBMS is 1bit; When value is 0, represent that this UE does not receive the MBMS business, when value is 1, represent that this UE is receiving the MBMS business; After the professional receiving status information of this MBMS is known in the base station, when carrying out HO (Handover switches) judgement (during the select target sub-district); With reference to this information; When doing the HO judgement, UE is switched to co-frequency cell as far as possible, thereby guarantee that UE receives the professional continuity of MBMS.
Yet, report in the scheme at existing UE, but do not provide concrete implementation method.
