Description
Technical field
The present invention relates to wireless communication field, more particularly to a kind of local load bearing management method and equipment.
Background technology
E-UTRAN (evolved Universal Terrestrial Radio Access Network, evolution it is general
Terrestrial Radio Access Network) the network architecture as shown in figure 1, main be made up of eNB (evolved NodeB, evolution base station).
MME (Mobility Management Entity, mobile management examination question) uses S1-MME interface and eNB between
It is connected；ENB completes access network function, and idle port communication is passed through with UE (User Equipment, user equipment).It is attached for each
The UE of network, has a MME for it provides service, the MME is referred to as the service MME of UE.S1-MME interface is right for UE is provided
Chain of command is serviced, including mobile management and bearer management function.
S-GW (Serving Gate Way, gateway) is connected between eNB using S1-U interface, attached for each
The UE of network, has a S-GW for it provides service, the S-GW is referred to as the service S-GW of UE.S1-U interface provides use for UE
Family face services, and the user face data of UE is by S1-U GTP (GPRS (General Packet Radio Service, general point
Group wireless service technology) tunnel protocol) it is carried between S-GW and eNB and transmits.
User plane and chain of command agreement stack difference between UE and network is as shown in Figures 2 and 3.User plane protocol includes
PDCP (Packet Data Convergence Protocol, PDCP), RLC (Radio Link
Control, wireless connection control), MAC (Media Access Control, medium education) and PHY (Physical
Layer, physical layer) layer；Chain of command agreement includes RRC (Radio Resource Control, wireless heterogeneous networks) and NAS
(non-access) layer, wherein, rrc layer message needs the treatment by user plane protocol layer, then is eating dishes without rice or wine to be transmitted；NAS layers disappears
Breath is transmitted in eating dishes without rice or wine to be encapsulated in RRC information.
In existing LTE/LTE-A networks, the RRC/PDCP/RLC/MAC/PHY peer layers of UE are all located at same eNB
Interior, the NAS layers of peer layer of UE is located at and is established in the MME being connected for the S1 of the UE with above-mentioned eNB.
Traditional macro base station (macro eNB) individual layer overlay network can not meet people to data service rate and appearance
Amount increasing need.Therefore, the mode of layering networking is introduced for solving the problem：By in hot spot region, family room
The base station that the small overlay environment such as interior environment, working environment lays some low-power (is represented, i.e. this ground with local eNB below
Stand, the form such as including Femto/Pico/Relay), obtain the effect of cell splitting so that operator can provide the user more
High data rate, more inexpensive business.
Layering networking also brings certain negative interaction while network capacity is increased：Due to low-power base station cell
The coverage of (being represented with home cell or local cell below) is small so that the switching frequency and number of times of UE all increase
Plus, increased the risk that UE occurs communication disruption when switching over.
In order to reduce the frequency that UE is switched between macrocell (macro cell) and home cell (local cell)
The network design mode that rate, a kind of user plane and chain of command are separate is introduced into.As shown in figure 4, macro cell provide basis covering
Lid, local cell provide focus covering, there is data/signaling interface (wired/nothing between local cell and macro cell
Line interface), UE can be operated under macro eNB or local eNB.
Because the cell coverage area of local eNB controls is small, the UE of service is few, so being connected to the UE of local eNB
Tend to obtain more preferable service quality, such as：Obtain service rate higher, higher-quality link.Therefore, when being connected to
During the cell that the UE of macro eNB is controlled close to local eNB, local eNB can be switched to obtain local eNB offers
Service；When the cell that UE is controlled away from local eNB, it is necessary to be switched to the cell of macro eNB controls, to keep wireless
Connection.
Carried more than under the separate network architecture, when the region that UE is covered in only macro cell, the chain of command of UE
Connection and user plane connect (i.e. DRB：Data Radio Bearer, Data Radio Bearer) all in macro eNB；When UE movements
To macro cell and local cell it is overlapping covered when, UE all or part of user plane connection (DRB) be transferred
To home base stations, to obtain service transmission rate higher, chain of command connection stills remain in macro base station, to prevent chain of command from connecting
Connect handoff failure and cause UE call drops.
Fig. 5 shows the network architecture of a kind of use chain of command and user plane isolation technics, and UE is connected to two simultaneously
ENB, M-L interfaces represent the logic interfacing between macro eNB and local eNB in figure.SRB (the Signalling of UE
Radio Bearer, Signaling Radio Bearer) it is retained on macro eNB, and all or part DRB (Data Radio
Bearer, Data Radio Bearer) PDCP/RLC/MAC/PHY part be maintained on local eNB.The upstream data of UE is reached
SGW (gateway) is forwarded directly to after local eNB, the downlink data of UE is forwarded directly to local eNB after reaching SGW,
So as to reduce processing loads of the macro eNB to UE packets.Under the framework, positioned at local eNB carry protocol stack such as
Shown in Fig. 6.
Fig. 7 shows another kind using chain of command and the network architecture of user plane isolation technics.Under the framework, it is located at
The protocol stack that local eNB are carried is as shown in Figure 8.
In HetNet, (Heterogeneous Network, heterogeneous network are made up of, such as different size, type cell
Including：Macro cell, local cell) under scene, because local cell coverages are small, UE slightly movements will be triggered
Switching, therefore, it can that the user plane of UE only is switched into local eNB.In order to support this characteristic, it is necessary to solve how to manage and
The problem of local cell resources is distributed, but not yet has corresponding solution at present.
The content of the invention
A kind of local load bearing management method and equipment are the embodiment of the invention provides, is used to realize in separated network is carried
Bearing resource to home cell is managed.
Local load bearing management method provided in an embodiment of the present invention, including：Macro base station receives the user of home base stations configuration
Dedicated resource information；User's dedicated resource information that the macro base station configures the home base stations, and the macro base station is matched somebody with somebody
The local public resource information put, is sent to respective user equipment, to indicate the respective user equipment to carry out resource distribution.

Information.Wherein, bearing modification response of the DRB dedicated resource informations that the UE is reconfigured on local eNB from step 2 disappears
Breath.
Step 4：After corresponding UE completes RRC connection reconfiguration operations, return to RRC connections to macro eNB and reconfigure completion
(RRC Connection Reconfiguration Complete) message.
As shown in figure 11, if local eNB determine modification UE MAC or the proprietary configuration information of physical layer, perform with
Lower flow：
Step 1：Local eNB send bearer update request (Bear Modify Request) message and give macro eNB,
The context id information of UE, such as AP ID are carried in the request message.Optionally, suggestion can also be carried in the request message
MAC configurations and proprietary physical layer configurations change information etc..
Step 2：Macro eNB organize and send bearer update response (Bear Modify Response) message to give
local eNB.This step is optional.
Step 3：Macro eNB are organized and are sent RRC and reconfigure (RRC Connection Reconfiguration) and disappear
Breath, to notify that corresponding UE (UE i.e. corresponding with the AP ID carried in bearer update request message) performs reconfiguration operation.This disappears
MAC layer or physical layer Proprietary Information that UE is reconfigured on local eNB can be included in breath, optionally, can also be included
The information such as the resource reconfigured on macro eNB.
Step 4：After corresponding UE completes RRC connection reconfiguration operations, return to RRC connections to macro eNB and reconfigure completion
(RRC Connection Reconfiguration Complete) message.
