Description

A kind of method and apparatus of connection reconstruction
Technical field
The present invention relates to communication technical field, relate in particular to a kind of method and apparatus of connection reconstruction.
Background technology
Statistics shows, traditional macro base station (Macro eNB) individual layer overlay network can not meet the ever-increasing demand of data service rate and data capacity.Therefore, the mode that 3rd Generation Partnership Project (3GPP) has been introduced layering networking addresses this problem: by hot spot region, the little overlay environment such as family's indoor environment, working environment lays some lower powered home base stations (Local eNB), obtain the effect of cell splitting, make operator to provide more high data rate, business more cheaply for user, this home base stations can comprise the forms such as Home eNodeB (Femto), Pico cell (Pico), relaying (Relay).
In hierarchical network under existing layering networking mode as shown in Figure 1, macro base station (or macrocell (Macro cell)) provides basis to cover, home base stations (or home cell (Local cell)) provides focus to cover, between home base stations (or home cell) and macro base station (or macrocell), have data/signaling interface (wire/wireless interface), UE can be operated under macro base station (or macrocell) or home base stations (or home cell).The network architecture of this hierarchical network is identical with the network architecture of Long Term Evolution (LTE) system.Mobility Management Entity (MME) or gateway (S-GW) connect macro base station and home base stations simultaneously.
The cell coverage area that Local eNB controls is little, and the subscriber equipment (UE) that is connected to 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 LocaleNB 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.Because Local eNB quantity is many, it is little to cover, between the community that causes UE needs frequently to be controlled at community and the Local eNB of Macro eNB control, switch.
In LTE system, when UE switches unsuccessfully, Radio Link Failure (Radio Link Failure, RLF), Radio Resource is controlled (Radio Resource Control, RRC) connect reprovision failure or integrity check unsuccessfully etc. during situation, trigger UE and carry out RRC connection reconstruction process, the object of process of reconstruction is to recover Signaling Radio Bearer 1(Signaling Radio Bearer 1, SRB1) and recover fail safe.Process of reconstruction as shown in Figure 2, mainly comprises the following steps:
Step 201:UE hangs up except Signaling Radio Bearer 0(Signaling Radio Bearer 0, all radio bearers (Radio bearer, RB) outside SRB0);
Step 202:UE replacement medium access is controlled (Medium Access Control, MAC) layer, use default configuration to carry out community selection course, this default configuration comprises that default physical layer is joined, MAC layer configures and semi-continuous scheduling (Semi-Persistent Scheduling, SPS) configuration;
Step 203: when UE selects suitable community (suitable cell), Ci community sends RRC connection reconstruction request message to base station, comprises the identification information of UE in this message;
Step 204: the RRC connection reconstruction request message of UE is received in base station, if allow UE to rebuild (this base station side is preserved the contextual information of this UE), sends RRC connection reconstruction message to UE, in this reconstruction message, writes wireless resource configuration;
Step 205:UE recovers SRB1 after receiving RRC connection reconstruction message, simultaneously according to this, rebuild more new key of security information in message, and Signaling Radio Bearer 2(Signaling Radio Bearer 2, SRB2) and all private radios carryings (Dedicated Radio Bearer, DRB) be still suspended, if comprise wireless resource configuration (physical layer configurations in this reconstruction message, the configuration of MAC layer, SPS configuration, SRB1 configuration etc.), UE according to this wireless resource configuration to bottom (PDCP (PDCP), wireless link is controlled (RLC), MAC and physical layer) be configured, configure rear UE and completed message to base station transmission RRC connection reconstruction,
Step 206: base station receives that RRC connection reconstruction completes message, and RRC connection reconstruction process completes, in order to recover SRB2 and DRB, base station is receiving that this reconstruction completes after message, sends RRC and connects reallocation message, to recover SRB2 and DRB to UE;
Step 207: be article one reallocation message after process of reconstruction if the RRC that UE receives connects reallocation message, recover SRB2 and all DRB, and carry out bottom configuration according to the content of reallocation message, reprovision completes, SRB2 and DRB have also just recovered, and UE returns to RRC connection reprovision and completes message to base station.
The in the situation that of layering networking, a lot of coverages of existence in network and type be different base station all, has formed heterogeneous network, and the Local eNBXia community in heterogeneous network can adopt the community of backward compatibility, can be the community of newtype.If the community of backward compatibility, UE can residently also can access Cong Gai community.If the community of newtype, this community may just can not provide the resident of Idle state UE, and Idle state UE can not access Cong Gai community, but this community can provide transfer of data for the UE of connected state, the UE of connected state can be switched to this community from other community, also can cut out.
If there is Radio Link Failure in backward compatibility community in UE, if the Serving cell before not searching out when UE carries out Cell searching so, will initiate to rebuild in other community, if there is radio link failure in UE in newtype community, UE can only re-start Cell searching so, and then initiates connection reconstruction in other community.Because the cell coverage area under Local eNB is less, UE probably rebuilds in other community, and because other community does not have the contextual information of UE, this will cause the reconstruction failure of UE.
