On figa schematically shows a block diagram of the sequence of operations of another embodiment of the method of transmission of user access control between base stations, which includes the following:

301: the first base station transmits a request message for establishing the x2 interface to the second base station, where the message carries the ID information of the CSG supported by the first base station.

302: second base station transmits a response message for establishing the x2 interface to the first base station, where the message carries the ID information of the CSG supported by the second base station.

If necessary, the second base station may verify whether the accepted CSG ID the same as the CSG ID sent in the broadcast mode transmission of the second base station; if the received CSG ID is not the same as the CSG ID sent in the broadcast mode transmission of the second base station, the second base station refuses to establish an x2 interface with the first base station.

The CSG ID information on the stages 301 and 302 may represent an access mode cell, or a combination of CSG ID and access mode of the cell.

In steps 301 and 302, the second base station may also transmit a request message for establishing the x2 interface to the first base and the second base station may also transmit a response message for establishing a transfer service to the first base station.

303: the First base station transmits a request message for transfer to the second base station via the x2 interface, where the request message transfer service transfers information about membership of the UE in the CSG in the first base station.

Membership information is used to identify whether the CSG UE

304: second base station compares whether the CSG ID of the second base station is the same as the CSG ID of the first base station.

If necessary, the first base station may also compare whether the CSQ ID supported by the first base station, the same as the CSG ID of the second base station, passed in the message of the x2 interface.

A: If the CSG ID supported by the second base station is the same as the CSG ID supported by the first base station, transmit the membership information of the UE at the first base station in a transfer request service, and the second base station determines that the information the policy on membership of the UE in the CSG in the first base station, received from the first base station, at this time still is valid, performs the access control in accordance with the membership information of the UE to the CSG in the first base station and the access mode of the second base station, and performs step 306.

If the second base station is in the closed CSG, and membership information of the UE to the CSG in the first base station, adopted by the second base station, while the UE belongs to the CSG cell, a request for transfer of UE will be accepted.

If the second base station is in the closed mode, CSG, and membership information of the UE to the CSG in the first base station, adopted by the second base station, is that the UE does not belong CSG cell, the transfer request service for a given UE will be rejected.

If the second base station is in a hybrid mode, CSG, the second base station receives the request for transmission service UE, and allocates resources for the UE in accordance with the accepted information about the CSG membership

306: If the access is successful, the second base station transmits a confirmation message about the transfer service to the first base station and performs step 307; if the access control fails, it returns a message about the failed transmission of the subscriber, and the procedure ends.

307: After successful access of the UE to the second base station to the second base what I station transmits a request for transmission service in MMA.

308: the MME returns a confirmation message to transfer to the second base station.

At step 306, for transmission to subscriber service within the same home gateway base station (gateway home EnodeB, HeNB GW), GW HeNB may terminate the message transmission service, and when it is not needed to transmit the request message to the transmission service in MMA, that is, at step 307 HeNB GW returns a confirmation message transfer service to the second base station.

When the x2 interface exists between the two base stations, the UE can perform the transfer between the given two base stations via an x2 interface. At the stage of preparation for the transfer of perform access control and resource allocation, but the second base station may not receive the CSG cells to which access is permitted for the UE, from the database of the subscription, so that the UE without access rights will be handed over to the CSG cell and will be illegal to use network resources. For a CSG cell with a hybrid access mode, the second base station, preferably, cannot allocate resources to the UE, belonging to the CSG cell, which affects the normal service of the UE in a cell of the CSG. In the embodiment of the present invention the base station establishes a connection via the x2 interface and perform the interaction is with the exchange of information about membership in the GSG, preventing the transfer of UE without granting access to another CSG cell, and, thus, ensure the proper maintenance of the UE in a cell of the CSG. For a CSG cell with a hybrid access mode, the second base station determines whether or not the UE CSG cell, performing the interaction of messages with neighboring CSG base station via the x2 interface, so that it is preferable to allocate resources to the UE belonging to the CSG cell, providing power for the UE belonging to sauté CSQ for the preferred use of the resources on which it was signed.

In Fig. 3b schematically shows a block diagram of the sequence of operations of another embodiment of the method of transmission of user access control between base stations. This alternative implementation is approximately the same as option implementation shown in Fig. 3A. The difference consists in the following steps.

305b: If the IDs of the CSG supported by the second base station and the first base station are different, the second base station transmits a request message to the access control MME through the HeNB GW, where the message contains the CSG ID and access mode of the second base station.

305M: the MME transmits the access control to the second base station through the HeNB GW, where the message may carry information about the membership of the UE in the CSG in the second base station.
