Description
Technical field
The present invention relates to the communications field, and particularly, (The 3 to relate to 3GPP
RdGeneration Partnership Project, the 3G (Third Generation) Moblie partnership project) the mobile communication system Long Term Evolution of Ti Chuing (Long Time Evolution, LTE) multimedia broadcast multi-broadcasting business under the framework (Multimedia Broadcast Multicast Service, MBMS) resource allocation methods and system.
Background technology
Along with the development of network architecture flattening and the appearance of the removable access way of multiple high-speed wideband, make the wireless communication system of evolution that higher transmission rate, shorter transmission delay, lower cost can be provided, support mobility between the inner connecting system of 3GPP and the mobility between 3GPP connecting system and the non-3GPP connecting system or the like simultaneously, impel mobile communications network to propose the framework theory of future generation of LTE/SAE (System Architecture Evolution, System Architecture Evolution).
At present the framework of SAE as shown in Figure 1, network element wherein has:
EUTRAN (Evolved UTRAN, the wireless access network of evolution): be follow-on wireless access network, higher up-downgoing speed, lower transmission delay and reliable more wireless transmission can be provided.
MME (Mobility Management Entity): chain of command functional entity, be in charge of and store UE (User Equipment, subscriber equipment) context (such as UE sign, mobility management states, user security parameters etc.), distribute temporary mark, when UE quarters at this tracing area or this network, be responsible for this user is carried out authentication for the user.
SAE GW: the user plane functions entity, the user face data route is handled, and is divided into two kinds of Serving and PDN (outer data network).Serving SAE GW is mobile anchor point between SAE system and traditional 3GPP system and the mobile anchor point between the e-Node B; PDNSAE GW: termination is in the downlink data of the UE of idle state, when the downlink data that mails to UE arrives, initiates paging, and the context of management and storage UE is such as IP bearer service parameter and network internal routing iinformation etc.
The LTE/SAE network has the function of activation, maintenance, deactivation carrying as access and the bearer network of PDN, and the handoff functionality that continues to provide data service for the mobile subscriber.
In order to adapt to the development of future mobile communications, 3GPP proposes to adopt MBMS (Multimedia Broadcast Multicast Service, multimedia broadcast multi-broadcasting business) on the SAE/LTE framework.
And very big difference is arranged based on the MBMS framework of WCDMA (Wideband Code Division Multiple Access, wide code divides multiple access) system with based on the MBMS framework of SAE/LTE system.
In the WCDMA system, the MBMS business still relates to RNC (Radio NetworkController, radio network controller), this is because of the business of MBMS as a kind of point-to-multipoint, require downstream Node B (base station) to carry out synchronously, to satisfy the user when reception is professional from the identical MBMS of a plurality of base station/sub-districts, the data that can carry out physical layer merge, so that improve the reception of MBMS business.Simultaneously, RNC also has functions such as scheduling of resource concurrently, to realize a plurality of MBMS business in RNC and subordinate's service in base station transfer of data, carries out rational resource allocation and scheduling, realizes the optimization of Radio Resource.
For the MBMS of SAE/LTE system, need a similar entity to realize functions such as node is synchronous, resource coordination.For this reason, 3GPP proposes to introduce the MBMS-GW logic entity in the SAE/LTE framework, this entity is as BM-SC (Broadcast andmulticast Service Center, the BroadCast MultiCast Service center) and a node between the e-Node B, it is the IAD of network, be responsible for the relevant message signaling relevant of processes user data, do not relate to wireless network parameter, can also realize synchronous between MBMS-GW and the e-Node B simultaneously with session.BM-SC is connected with content service provider/multicast broadcast source (ContentProvider/Multicast Broadcast Source), finishes converging of data.In addition, also introduce MCE (MBMS Coordination Entity, multimedia broadcast multi-broadcasting business coordination function entity), to realize the Radio Resource coordination function of e-Node B.
The method that MCE carries out resource allocation has two kinds: static allocation and dynamic assignment.Static allocation is simpler, can come static configuration according to planning, does not consider to receive professional UE (UserEquipment, subscriber equipment) position and quantity, SFN (Single FrequencyNetwork, MBMS Single Frequency Network) is in case determine to cause the wasting of resources easily with regard to no longer changing.Dynamic assignment need be considered position and the quantity of UE, the mobility of UE can cause the dynamic change of SFN, has influence on other SFN easily, and needs e-Node B to report the situation of each sub-district, if the corresponding a plurality of e-Node B of MCE, the message traffic of MCE and e-Node B can be very big so.
Therefore, the mobility of UE has certain influence for the resource allocation of MBMS, how to guarantee that therefore the reception of MBMS when UE moves can not be ignored and need the problem that solves with regard to becoming one, and relevant therewith technology still is unrealized at present.
