1. A network handover method, comprising:
- receiving, by a base station gateway, a handover request message or a radio link establishment request message that is sent by a source cell radio network controller (RNC); and
performing, by the base station gateway an access control process or initiating the access control process to a core network in response to receiving the handover request message or radio link establishment request message from the source cell RNC;
wherein receiving the handover request message or the radio link establishment request message that is sent by a source cell RNC comprises;
when the handover request message or the radio link establishment request message that is received by the base station gateway carries a closed subscriber group identifier (CSG ID) of a target cell base station, verifying, by the base station gateway, the CSG ID; and
when verification fails, generating, by the base station gateway, a radio link establishment failure message or a handover failure message and sending the radio link establishment failure message or the handover failure message from the base station gateway to the source cell RNC, or when verification fails, generating, by the base station gateway, a handover response message or a radio link establishment response message that is added with a real closed subscriber group identifier (CSG ID) and sending the handover response message or the radio link establishment response message from the base station gateway to the source cell RNC.

7. A network handover method, comprising:
-
receiving a cell update message at a source cell radio network controller (RNC), the cell update message having been sent by a user equipment (UE) to a base station gateway and from the base station gateway to the source cell RNC; sending, by the source cell RNC, an access control request message to a core network or the base station gateway, wherein the access control request message carries a closed subscriber group identifier (CSG ID) of a target cell base station, the access control request message being sent in response to receiving the cell update message; performing access control, by the core network or the base station gateway that received the access control request message, according to the CSD ID carried in the access control request message; receiving, by the source cell RNC, access control response message sent by the core network or the base station gateway; and sending, by the source cell RNC, a handover request message or a radio link establishment request message to the base station gateway, wherein the handover request message or the radio link establishment request message carries the CSG ID and member state information. - View Dependent Claims (8)

9. A network handover method, comprising:
-
receiving, by a base station gateway, an uplink signaling transmission indication message sent by a target cell base station after the target cell base station receives a cell update message sent by a user equipment (UE), wherein the cell update message carries a UE identifier and/or UE capability indication information, and wherein the target cell base station is a micro cell base station; performing, by the base station gateway, an access control process or initiating the access control process to a core network in response to receiving the uplink signaling transmission indication message sent by the target cell base station; and sending, by the base station gateway, the uplink signaling transmission indication message to a source cell radio network controller (RNC), wherein the uplink signaling transmission indication message carries the cell update message and/or an access control completion indication message. - View Dependent Claims (10, 11)

12. A base station gateway, comprising:
-
a receiver, configured to receive a handover request message or a radio link establishment request message that is sent by a source cell radio network controller (RNC), wherein the handover request message or the radio link establishment request message carries a closed subscriber group identifier (CSG ID); a processor, configured to; verify the handover request message or the radio link establishment request message in response to receiving the handover request message or the radio link establishment request message that is sent by the source cell RNC; and in response to verification failing, generating a first message, wherein the first message comprises a radio link establishment failure message or a handover failure message, or a handover response message, or a radio link establishment response message that is added with a real closed subscriber group identifier (CSG ID); and a transmitter, configured to send the first message to the source cell RNC.

13. A base station gateway, comprising:
-
a receiver, configured to receive an uplink signaling transmission indication message sent by a target micro cell base station, wherein the uplink signaling transmission indication message carries a cell update message and the cell update message carries a user equipment (UE) identifier and/or user equipment (UE) capability indication information; a processor, configured to perform an access control process; and
/or configured to initiate an access control process to a core network in response to receiving the uplink signaling transmission indication message sent by the target micro cell base station; anda transmitter, configured to send the uplink signaling transmission indication message to a source cell radio network controller (RNC), wherein the uplink signaling transmission indication message carries the cell update message and/or an access control completion indication message.
