Technical field
The present invention relates to mobile communication technology, particularly a kind of changing method of subscriber equipment and home evolved base station.
Background technology
Fig. 1 is E-UTRAN (Evolution-Universal Terrestrial Radio Access Network in R9 (version 9), the global grounding wireless access network of evolution) network architecture that comprises HeNB (Home eNB, home evolved base station).Between eNB (evolution base station), it is X2 interface, eNB and MME (Mobility Management Entity, Mobility Management Entity) between, be the S1 interface, HeNB can directly be connected with MME, also can pass through a centralized node HeNB GW (Gateway, gateway) be linked into MME, there is no interface between HeNB, HeNB can only be connected with a HeNB GW simultaneously.
Fig. 2 is the S1 switching flow schematic diagram between HeNB, in the above-mentioned network architecture, there is no X2 interface between HeNB, and therefore switching is all by the S1 Interface realization.Process as shown in Figure 2, comprises the steps:
If step 201 source HeNB thinks UE (User Equipment, subscriber equipment) can be switched to Target cell, send handover required (handover request) message to MME, carry CSG (Closed Subscriber Group, the closed user group) ID (sign) of Target cell in message.If Target cell is mixed mode, also need to carry access module;
The allowed CSG list of the CSG ID of the Target cell that step 202, MME report according to source and the UE of preservation (allowing the list of access CSG) carries out access control to UE.
If step 203 UE allows, MME sends handover request (handover request) message to target side, carries the CSG ID of Target cell in message.If Target cell is the mixed mode community, need to carry UE membership IE (UE information about firms unit; IE:information element, information unit).
Whether the CSG ID that step 204, target side confirmation are received in handover request message and the CSG ID of oneself mate.If confirm successfully, will distribute suitable resource at source.If if Target cell is the mixed mode community, need to carry out different receiving control and speed control according to UE membership.
The deficiencies in the prior art are: when the UE of Intra-CSG (in CSG) is switched between HeNB at present, only have by the S1 interface and switched this kind of technical scheme.
