Wherein, access procedure is synchronous etc. including uplink/downlink.
Further, user equipment access target BS includes following three kinds of modes in step 103：
If mode A, macro base station are synchronous with target BS, user equipment access target BS includes：
User equipment determines that itself has been successfully accessed target BS.
If mode B, macro base station and target BS are asynchronous, and the Special leader of target BS is included in carrying separation order
Code preamble, then user equipment access target BS include：
User equipment accesses target BS according to the dedicated preamble using non-competing Random Access.
If mode C, macro base station and target BS are asynchronous, and do not include the special of target BS in carrying separation order
Preamble, then user equipment access target BS include：

Below for the network scenarios shown in Figure 12（UE from Macro eNB overlay area be moved to Macro eNB with
Local eNB's is overlapping covered）, and so that UE needs part or all of DRB being separated to Local eNB as an example, to this hair
The process that bright embodiment carries out carrying separation switching is described in detail.
Example one,
Referring to Figure 13, the method that the present embodiment carries out carrying separation switching is located at macrocell applied to UE（macro
cell）With target home cell（Target local cell）It is overlapping covered in, this method comprises the following steps：
Step 131, macro cell judge whether connected UE needs to carry out carrying separation switching；
If so, then performing step 132；
If it is not, then terminating this flow.
It is preferred that, macro cell can be reported according to UE measurement, UE positional information or UE business information, it is determined that
Whether the UE needs to carry out carrying separation switching.
Step 132, macro cell send carrying separation order to UE（Such as " RB handover requests "）, wherein, the carrying
At least include in separation order：Target local cell mark, for indicating that UE needs to be separated to target local cell's
The configured information of carrying, target local cell configuration information；
Further, target local cell configuration information includes target local cell MAC resource distributions and physics
Layer resource distribution.
For example, macro cell determine UE part or all of DRB being transferred to local cell, UE SRB is still protected
Hold in macro cell.
Further, the RB handover requests use a kind of feasible implementation of RRC information：Macro eNB and local
ENB configuration information is two sets separate configuration parameters, UE can according to the macro eNB included in the RRC information with
Local eNB different configuration parameters are respectively to the corresponding entities of macro and local（As MAC layer entity and physical layer are real
Body）Carry out parameter configuration.
Step 133, UE set up target local cell correspondences after the carrying separation order from macro cell is received
MAC layer entity and PHY entities, and according to carrying separation order in target local cell MAC resource distributions and physical layer
Resource distribution is configured to newly-established MAC layer entity and PHY entities；
The PDCP entities and RLC entities that step 134, UE will need to be separated to target local cell DRB are mapped to mesh
Mark the corresponding MAC layer entities of local cell and PHY entities；
If specifically, being included in carrying separation order needs to be separated to the target local cell corresponding RLC/ of DRB
PDCP is configured, then UE rebuilds the corresponding RLC/PDCP entities of the DRB；
If not including in carrying separation order needs the corresponding RLC/PDCP of DRB for being separated to target local cell to match somebody with somebody
Put, then UE, which need to only change, needs the mapping relations of the corresponding RLC/PDCP entities of the DRB and MAC entity separated.
Step 135, UE judge whether macro cell are synchronous with local cell；
If so, then performing step 136；
If it is not, then performing step 137；
Step 136, UE determine itself to be successfully accessed local cell, and perform step 138；
Step 137, UE initiate to access to target local cell；
Wherein, access procedure is synchronous etc. including uplink/downlink；When UE successfully completes the uplink/downlink with target local cell
After synchronization, then UE determines access target Local eNB successes.
Further, if carrying separation order（That is RB handover requests）In include be used for access the special of target local cell
Lead code preamble, then UE target local is accessed by the way of non-competing Stochastic accessing according to the dedicated preamble
cell；
If carrying separation order（That is RB handover requests）In do not include be used for access the special of target local cell
Preamble, then UE uses compete Random Access and access target local cell；Wherein, UE is to target local cell
The msg3 of transmission（Message 3）Middle carrying UE identification information, such as C-RNTI；And target local cell are according to the msg3 received,
The corresponding RRC confirmation messages of msg3 or MAC CE or UL grant are carried in the msg4 of return；
It is preferred that, the msg3 can be the RRC information or MAC CE newly defined；Msg4 is dispatched using C-RNTI in itself.
Step 138, UE return to carrying after access target local cell, to macro eNB and switch successfully message（Such as
" RB switches successfully message "）.
It should be noted that the carrying separation order and carrying in the present embodiment switch successfully message and can newly defined
RRC information, can also use defined RRC information in agreement, such as RRC connection reallocation messages.
