Embodiment of the method three,

What the present embodiment described is the method that MME performs CSG inspection in SeNB adding procedure, and Fig. 3 is the schematic flow sheet of method described in the present embodiment, comprises the following steps:

Step 301:MeNB obtains the RRM measurement result that UE reports, and is defined as described UE initiation SeNB interpolation flow process according to the RRM measurement result that described UE reports.

SeNB can be HeNB in the present embodiment.

Described RRM measurement report can comprise: the CSG identity state of described UE in the CSG or mixed cell of SeNB or described UE are the PLMN ID list of member identities in the CSG/ mixed cell of SeNB.

In the present embodiment, the deployment of MeNB and SeNB can be divided into following several situation:

1) MeNB is macro eNB, SeNB is mixing or closed pattern HeNB;

2) MeNB and SeNB is mixing or closed pattern HeNB, and the CSG ID of MeNB with SeNB is not identical;

3) MeNB and SeNB is mixing or closed pattern HeNB, and the CSG ID of MeNB with SeNB is identical.

In situation 1) or 2) under, MME, before obtaining CSG check result, also needs the checking performing CSG access control or member identities;

In situation 3) under, do not need to perform CSG access control or membership identity verification by MME, but access this SeNB with this UE in the CSG identity state that the CSG cell of MeNB is identical.

Step 302:MeNB sends the message being used for SeNB interpolation request to MME by S1 interface, can comprise CSG ID, access module, PLMN ID, CSG identity state, the base station IDs corresponding to CSG ID, E-RAB information, source identification information, target identification information in this message.

Due between MeNB and SeNB without X2 interface, so MeNB by S1 interface to MME send be used for SeNB add request message.

Wherein, CSG ID and access module are CSG ID and the access module of SeNB community, the PLMN ID of PLMNID to be MeNB be SeNB community that UE selects.

CSG identity state is the identity state of acquiescence or the identity state that reports of UE or the identity state identical in MeNB community with UE.E-RAB information is the E-RAB information of the UE that will be transferred to SeNB.Source identification information and target identification information are respectively eNB ID and/or the TAI information of MeNB and SeNB.

The message of adding request for SeNB that step 303:MME receives, obtain the CSG subscription information of UE from HSS according to the CSG ID in described message of adding request for SeNB, the CSG ID added in request message for described SeNB carries out CSG inspection, obtains CSG check result.

Described CSG checks and can comprise: CSG access control or membership identity verification, to determine whether UE can access the CSG cell of SeNB, or accesses the mixed cell of SeNB with member or non-member identity.

Optionally, MME can also perform the checking of CSG ID and access module, to verify CSG ID and/or the access module legitimacy of the CSG/hybrid community of SeNB.

If adding in the message of request for SeNB that MME receives comprises E-RAB information, then this CSG ID and corresponding E-RAB information can be used for subsequent charging purposes by MME.

Optionally, MME judges MeNB and SeNB as HeNB, and the CSG ID of MeNB with SeNB is identical, then MME does not perform CSG inspection.

If adding in the message of request for SeNB of receiving of MME comprises CSG mark, but do not comprise access module or the access module that comprises is in closed situation, MME carries out CSG and checks the CSG cell identified to determine whether allowing described UE to access this CSG ID.

If adding in the message of request for SeNB of receiving comprises CSG mark and access module, and this access module is in mixing situation, and MME carries out CSG and checks to determine that UE accesses the mixed cell of the SeNB that CSG ID identifies with member or non-member identity.

Step 304: if CSG check result is described UE can be accessed by SeNB community, then described CSG check result is included in and adds in the message of request for SeNB by described MME, and sends the described message for SeNB interpolation request to SeNB.

Step 305a-305b: described SeNB judges whether that accepting described SeNB adds request, such as, according to the CSG check result received from MME and current load situation, if accept, then carry out resource reservation according to described SeNB E-RAB information in request of adding, and generate SeNB interpolation request acknowledge message according to described SeNB interpolation request, send described SeNB interpolation request and confirm message to MeNB.

Described SeNB adds in order can comprise idle wireless resource configuration information.Also comprise: source and target identification information, such as, eNB ID and/or TAI information.Due between SeNB and MeNB without X2 interface, this message is first sent to MME by SeNB, then is sent to MeNB by MME.

Step 306a-306b:MeNB receives after this SeNB adds request acknowledge message, carries out cell synchronous and Stochastic accessing by RRC proprietary signaling instruction UE and SeNB, and carries out Radio Resource and reshuffle.

MeNB receive UE reshuffled message after send SeNB and reshuffled message to SeNB.

Due between SeNB and MeNB without X2 interface, this message is first sent to MME by MeNB, then is sent to SeNB by MME.

Step 307:MeNB sends E-RAB and revises Indication message to MME, wherein comprises the E-RAB information that will be transferred to SeNB, such as, and GTP tunnel information etc.

Step 308:MME and SGW, alternately to shift the S1-U tunnel of the part E-RAB of UE, then replys E-RAB to MeNB and revises acknowledge message.

It should be noted that in step 307, E-RAB amendment Indication message can send to MME by SeNB, instead of send to MME by MeNB, MME receives rear reply E-RAB and revises acknowledge message to SeNB.
