Description
Technical field
The present invention relates to wireless communication field, relate in particular to a kind of local load bearing management method and equipment.
Background technology
E-UTRAN(evolved Universal Terrestrial Radio Access Network, the general continental rise wireless access network of evolution) the network architecture as shown in Figure 1, mainly by eNB(evolved NodeB, evolution base station) form.
MME(Mobility Management Entity, mobile management examination question) with between eNB adopt S1-MME interface to be connected; ENB completes Access Network function, with UE(User Equipment, subscriber equipment) pass through idle port communication.The UE that is attached to network for each, has a MME to provide service for it, and this MME is called the serving MME of UE.S1-MME interface, for UE provides chain of command service, comprises mobile management and bearer management function.
S-GW(Serving Gate Way, gateway) with between 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, and this S-GW is called the service S-GW of UE.S1-U interface provides the service of user's face for UE, and the user face data of UE is by S1-U GTP(GPRS(General Packet Radio Service, general packet radio service technology) tunnel protocol) be carried between S-GW and eNB and transmit.
User's face between UE and network and chain of command protocol stack are respectively as shown in Figures 2 and 3.User plane protocol comprises PDCP(Packet Data Convergence Protocol, PDCP), RLC(Radio Link Control, wireless connection control), MAC(Media Access Control, media access control) and PHY(Physical layer, physical layer) layer; Chain of command agreement comprises RRC(Radio Resource Control, and Radio Resource is controlled) and NAS(non-access) layer, wherein, rrc layer message need to be passed through the processing of user plane protocol layer, then transmits eating dishes without rice or wine; NAS layer message is transmitted in eating dishes without rice or wine to be encapsulated in RRC message.
In existing LTE/LTE-A network, the RRC/PDCP/RLC/MAC/PHY peer layer of UE is all positioned at same eNB, and the NAS layer peer layer of UE is positioned at above-mentioned eNB has set up the MME that the S1 for this UE is connected.
Traditional macro base station (macro eNB) individual layer overlay network can not meet people to data service rate and the ever-increasing demand of capacity.Therefore, the mode of layering networking is introduced into this problem that solves: by little overlay environments such as hot spot region, family's indoor environment, working environments, lay some lower powered base stations (below with local eNB, represent, it is home base stations, comprise the forms such as Femto/Pico/Relay), obtain the effect of cell splitting, make operator to provide more high data rate, business more cheaply for user.
Layering networking is when increasing network capacity, also brought certain negative interaction: because the coverage of low power base station community (representing with home cell or local cell) is little below, the switching frequency of UE and number of times all increased greatly, increased the risk that communication disruption occurs UE when switching.
The frequency of switching between macrocell (macro cell) and home cell (local cell) in order to reduce UE, a kind of user's face network design mode separated with chain of command is introduced into.As shown in Figure 4, macro cell provides basis to cover, and local cell provides focus to cover, and has data/signaling interface (wire/wireless interface) between local cell and macro cell, and UE can be operated under macro eNB or local eNB.
The cell coverage area of controlling due to local eNB is little, and the UE of service is few, so be connected to the UE of local eNB, often can obtain better service quality, as: obtain higher service rate, higher-quality link.Therefore,, when being connected to the UE of macro eNB and approaching the community that local eNB controls, can be switched to the service that local eNB provides to obtain local eNB; When community that UE controls away from local eNB, need to be switched to the community that macro eNB controls, to keep wireless connections.
Under the separated network architecture of above carrying, when UE is in the region of only having macro cell to cover, the chain of command of UE connects and is connected (being DRB:Data Radio Bearer, Data Radio Bearer) with user's face all at macro eNB; When UE moves to macro cell and local cell when overlapping covered, all or part of user's face of UE connects (DRB) and is transferred to home base stations, to obtain higher service transmission rate, chain of command connection still remains on macro base station, to prevent that chain of command from connecting handoff failure and causing UE call drop.
Fig. 5 shows a kind of network architecture that adopts chain of command and user's face isolation technics, and UE is connected to two eNB simultaneously, and in figure, M-L interface represents the logic interfacing between macro eNB and local eNB.The SRB(Signalling Radio Bearer of UE, Signaling Radio Bearer) be retained on macro eNB, and all or part DRB(Data Radio Bearer Data Radio Bearer) PDCP/RLC/MAC/PHY partly remain on local eNB.The upstream data of UE directly mails to SGW(gateway after arriving local eNB), the downlink data of UE directly mails to local eNB after arriving SGW, thereby has reduced the processing load of macro eNB to UE packet.Under this framework, be positioned at the protocol stack of local eNB carrying as shown in Figure 6.
Fig. 7 shows the another kind of network architecture that adopts chain of command and user's face isolation technics.Under this framework, be positioned at the protocol stack of local eNB carrying as shown in Figure 8.
At HetNet(Heterogeneous Network, heterogeneous network, by different sizes, type community, formed, as comprise: macro cell, local cell) under scene, because local cell coverage is little, UE slightly movement will trigger switching, therefore, can only user's face of UE be switched to local eNB.In order to support this characteristic, need to solve how to manage and distribute the problem of local cell resource, but not yet have at present corresponding solution.
