Description
Technical field
The present invention relates to the communications field, in particular to the update method of a kind of user plane path, Apparatus and system.
Background technology
Along with the development of wireless multimedia service, people are growing to the demand of high data rate and Consumer's Experience, thus power system capacity and covering to conventional cellular network propose high requirement.In tradition LTE cellular network, macro base station provides access service as unique sided access network element for UE.And to the demand of higher data rate and improving cellular network spectrum efficiency in order to meet user, third generation partner program (3rdGenerationPartnershipProject is referred to as 3GPP) introduces low power nodes (LowPowerNode is referred to as LPN) and provides access service as supplementing of macro base station for subscriber equipment (UserEquipment is referred to as UE).LPN has low cost, low-power, facilitates the features such as deployment, generally has focus to dispose and strengthens two kinds of deployment scenario of covering, can effectively improve the data rate of indoor or outdoors hot spot region high speed data transmission service, improves outlying district or cell edge covers.Usual LPN is alternatively referred to as little base station, including Home eNodeB (HomeNodeB is referred to as HeNB), femto base station (pico), Remote Radio Unit/head (RemoteRadioUnit referred to as RRU/RadioRemoteHead referred to as RRH), via node (RelayNode is referred to as RN) etc..Under focus deployment scenario, in order to reach higher data rate and spectrum efficiency, it is necessary to the intensive little base station of a large amount of deployment in region.But, owing under little base station, the coverage of small-cell (smallcell) is less, high speed moves the probability of the failure that switches when UE passes little base station and increases, and affects UE service continuity.In order to promote the UE travelling performance after introducing smallcell, propose in the industry by certain base station (as, macro base station) ensure basic covering, UE always keeps wireless heterogeneous networks (RadioResourceControl is referred to as RRC) to be connected with this base station, and smallcell as transmission node (transmissionpoint is referred to as TP) to provide more High Data Rate and to meet user and economize on electricity the method for demand.Under this system architecture, UE at least keeps being connected and using the Radio Resource under two base stations with two base stations, the Radio Resource polymerization of cross-node can be realized, this framework is commonly referred to dual link framework, Fig. 1 is according to dual link architectural configurations block diagram in correlation technique, as shown in Figure 1, what have certain management control ability in two base stations that UE connects is commonly referred to dominant base (mastereNB, referred to as MeNB), another base station is then called prothetic group station (SecondaryeNB is referred to as SeNB).After UE accesses MeNB, it is possible to adding flow process by SeNB and realize dual link, SeNB adds can carry out a series of management to this SeNB after successfully, as SeNB amendment, SeNB delete, SeNB change etc..
Under dual link framework, there is framework two kinds possible in user face, i.e. 1A framework in framework option1, or the 3C framework in framework option3, and wherein in framework option1, S1-U terminates at MeNB and SeNB,；Such as, the different user face carrying data of UE can be issued to MeNB and SeNB respectively by SGW, retransmits to UE.And in framework option3, S1-U terminates at MeNB, resident's Access Network (ResidentialAccessNetwork is referred to as RAN) side has carrying to separate, such as, downlink data in evolved packet system (EvolvedPacketSystem is referred to as EPS) carrying by the part data separating in a carrying to SeNB, then can be sent to UE by SeNB after arriving MeNB.Fig. 2 is according to dual link configuration diagram in correlation technique, in Fig. 2, left figure is framework option1 schematic diagram, in Fig. 2, right figure is framework option1A protocol stack schematic diagram, namely have employed framework option1, and the user face protocol stack on SeNB has independent PDCP (PacketDataConvergenceProtoco is referred to as PDCPl) and following protocol layer, separate without carrying.
On the other hand, under dual link framework, it is possible to HeNB is disposed as SeNB (or MeNB).In Long Term Evolution (LongTermEvolution is referred to as LTE) system, Home eNodeB is referred to as HeNB (homeeNB).The function that HeNB supports is basically identical with eNB, and HeNB and block core are drilled between process and eNB and the EPC between (EvolvedPacketCore is referred to as EPC) basically identical.Owing to the arrangement of HeNB is usually not little and large number of through the network planning of mobile operator, coverage.For management more easily and in order to support greater number of HeNB, under universal land radio access web E-UTRAN (EvolvedUTRAN) framework of evolution, between the S1 of HeNB and EPC connects, introduce new network element femto gateway HeNBGW (HomeeNBGateway).HeNB can pass through HeNBGW and connect mobile management entity (MobilityManagementEntity is called for short MME) as S1 agency.S1 data between HeNB and SGW optionally terminate at HeNBGW.There is X2 direct interface between HeNB, can carry out load balancing, handover optimization, information is mutual.
Under adopting dual link user's face frame structure 1A situation, in the moving process of UE, MeNB is required to be UE and adds new SeNB, or is replaced by the SeNB of this UE service.Owing to S1 user face data is respectively sent to MeNB and SeNB by SGW, if the mobile anchor point in S1 user face is positioned at core network element SGW, add or change procedure at SeNB, it is necessary to initiated pathupdate process by MeNB and carry information with the S1 updating SGW.Usual SeNB is little base station, little base station range is less and at hot spot region dense deployment, UE is in a large amount of dense deployment region, this little base station under the scene of movement, if SeNB interpolation/change procedure all need to be participated in mutual by core network element every time, bigger core network signalling load will be caused, and cause SeNB to manage the time delay of process.At SeNB by controlling under the scene that node is connected to SGW, if UE is at identical control node (such as, HeNBGW, or mobile anchor point MA) under HeNB (as SeNB) between move, the mobile anchor point in the S1 user face of UE can be located at control node (such as HeNBGW or MA), so can save some core net S1 Signalling exchanges and update with the user plane path carrying out UE.And in correlation technique under dual link framework, not yet have UE to change the HeNB under same control node as the method how updating S1 user face data path after SeNB.
