Provided is a Gs association establishment method, including: when a serving GPRS support node (SGSN) confirms that an SGs association of user equipment (UE) in an idle mode signalling reduction (ISR) activated state is released, the SGSN sending an update location request to a mobile switching centre/visiting location register (MSC/VLR) so that the SGSN establishes a Gs association for the UE with the MSC/VLR. Also provided is an SGSN. The embodiments of the present invention can establish a Gs association in time after an SGs association is released when the UE is in an ISR activated state, so that the UE will not be separated by the MSC/VLR in a hidden way, and the called service of the UE will not be affected, enhancing the service experience of the user. |
