Background technology

Along with fast development and the user of intelligent terminal constantly increase the demand of data service rate and capacity, traditional macro base station (Macro eNB) individual layer overlay network can not meet people's business demand.Therefore, (the 3rd Generation Partnership Project of 3G (Third Generation) Moblie standardization body, the mode of 3GPP) having introduced layering networking solves this problem: by hot spot region, family's indoor environment, it is home base stations (Local eNB) (comprising the forms such as femtocell base station (Femto)/micro-base station (Pico)/relaying (Relay)) that the little overlay environment such as working environment is laid some lower powered nodes, provide among a small circle and cover, obtain the effect of cell splitting, make operator to provide more high data rate for user, business more cheaply.In layering networking situation for strengthen mobile management or improve peak rate, the resource of the community of the multiple base stations of terminal possibility polymerization, also can support further a kind of network architecture of carrying separation, by subscriber equipment (User Equipment, UE) Radio Resource connects (Radio Resource Connection, RRC) only safeguard at Marco eNB, home base stations only possesses the functions such as transfer of data.

As shown in Figure 1, E-UTRAN is made up of base station (eNB) network architecture of the general land wireless network (Evolved Universal Terrestrial Radio Access Network, E-UTRAN) of evolution.ENB completes Access Network function, passes through idle port communication with UE.Between UE and eNB, not only exist chain of command to be connected but also exist user's face to connect.The UE that is attached to network for each, for it provides service, adopts S1-MME interface to be connected between MME and eNB by a Mobility Management Entity (Mobility Management Entity, MME).S1-MME interface, for UE provides chain of command service, comprises mobile management and bearer management function.

Between gateway (Serving GW, S-GW) and eNB, adopt S1-U interface to be connected, the UE that is attached to network for each, has a S-GW to provide service for it.S1-U interface provides the service of user's face for UE, and the user face data of UE is carried between S-GW and eNB and is transmitted by S1-U.

In existing hierarchical network as shown in Figure 2, macro base station (Macro eNB) provides basis to cover, lower powered Local eNB provides focus to cover, between Local eNB and Macro eNB, have data/signaling interface (can be wired or wireless interface), UE can be operated under Macro eNB or Local eNB.The cell coverage area UE little, service controlling due to Local eNB is few, so the UE that is connected to Local eNB often can obtain better service quality, as: obtain higher service rate, higher-quality link.Therefore,, in the time being connected to the UE of Macro eNB and entering the coverage of the corresponding community of Local eNB (being small-cell (Small Cell)), can transfer to the service that Local eNB provides to obtain Local eNB; When UE is during away from the coverage of the corresponding community of Local eNB, need to transfer to the community that Macro eNB controls, to keep wireless connections.

The network architecture shown in Fig. 2 can supported data carrying separate.Overlapping covered in Macro eNB community and Local eNB community, can will dispatch under base stations different being carried on of corresponding UE and transmit.Especially, below, give an example to realizing the network architecture that user's face separates with chain of command.Under which, when UE is in the region of only having Macro eNB community to cover, the chain of command of UE connects and is connected with user's face all at Macro eNB; In the time that UE moves to or approach Macro eNB community and Local eNB community overlapping covered, the user plane bearer (all or part of) of UE connects and is transferred to Local eNB, to obtain higher service transmission rate; Chain of command connection still remains on Macro eNB, the signaling consumption bringing to reduce frequent switching.
