Description
Technical field
The present invention relates to the digital mobile communication technical field, relate in particular to the distribution method of connection identifier in a kind of family base station system.
Background technology
Home eNodeB is the small base station of a kind of user's of being arranged on family or Administrative Area, is called Home NodeB in 3G (third generation mobile technology) system, is called for short HNB; Be called Home eNodeB in LTE (Long Term Evolution) system, be called for short HeNB.In order to reduce the core net impact of (Core Network is called for short CN), family base station system has been introduced femto gateway (HNB GW), and HNB GW is connected with core net, and HNB and HeNB are connected to HNB GW.
As shown in Figure 1, in the 3G system, the interface inheritance between HNB GW and core net the interface between macro base station and core net, all adopt the Iu interface, the interface between HNB and HNB GW is called Iu-h.Macro base station is relative Home eNodeB, and in the 3G system, macro base station refers to the NodeB (Node B) that directly is connected with core net, and in the LTE system, macro base station refers to the direct eNodeB (evolved Node B) that is connected with core net.As shown in Figure 2, in the LTE system, the interface that the interface between HNB GW and core net has also been inherited between macro base station and core net adopts the S1 interface, and the interface between HNB and HNB GW is called the S1-h interface.In family base station system, the processing of Radio Access Network application layer protocol (RANAP) and S1 Application Protocol (S1-AP) is completed in HNB and HeNB respectively, and HNB GW is mainly used in completing message and converges and distribute.
S1-AP message between macro base station in the LTE system (eNB) and core net on the S1 interface uses two signs to identify: the core net S1-AP signaling connection identifier (MME UE S1APID) that the base station S1-AP signaling connection identifier (eNBUE S1AP ID) that wireless access network (eNB) distributes and core net are distributed.UE initiates business and triggers S1 to connect the process of setting up, and wireless access network adds in the S1-AP message that sends to core net for this connects base station S1-AP signaling connection identifier of example allocation.Core net is processed according to message and is returned to S1-AP message to wireless access network, carry the MME UE S1AP ID of its distribution and the eNB UE S1AP ID in former S1-AP message in the S1-AP message of returning, because macro base station directly is connected with core net, the eNB UE S1AP ID that distributes is also unique on the S1 interface, so the base station eNB UE S1AP ID that carries in can be according to return messages when macro base station receives the S1-AP message that core net returns determines that the S1-AP signaling connects example.
Similar with the LTE system, in the 3G system between macro base station and core net the Iu signaling on the Iu interface adopt a sign to identify: radio network controller (RNC) distributes and adds Iu signaling connection identifier (Iu Signalling Connection Identifier) in Iu message or core net to and distribute and add Iu signaling connection identifier in Iu message to.
In family base station system, wireless access network comprises Home eNodeB and femto gateway two parts.For the LTE system, the processing of S1-AP message (comprise structure message and resolve message etc.), completed by HeNB, if eNB UE S1AP ID also adopts the mode identical with macro base station to distribute by HeNB, can't guarantee the uniqueness of eNB UE S1AP ID on the S1 interface.This is to be independently to carry out because different HeNB distributes the operation of eNB UE S1AP ID, if each HeNB all distributes eNB UE S1AP ID according to the mode identical with macro base station, in the time of will causing HNB GW to send S1-AP message to core net on the S1 interface, eNB UE S1AP ID is not unique on the S1 interface.In this case, after HNB GW received the message that core net returns, the message distribution that can't return to core net according to eNB UE S1AP ID was to correct HeNB.Similarly, for the 3G system, the Iu that wireless access network is initiated connects, if adopt the mode identical with radio network controller to distribute Iu signaling connection identifier (Iu Signalling Connection Identifier) by HNB, the problem that the Iu SignallingConnection Identifier that also exists different HNB to distribute may duplicate.
Summary of the invention
The technical problem to be solved in the present invention is to provide the distribution method of connection identifier in a kind of family base station system, avoiding wireless access network in family base station system is to send to the interface message of core net to distribute the access signaling connection identifier that repeats, and makes wireless access network can identify the interface message that core net is returned.
