(PHS, Personal Handy Phone System), Wideband Code Division Multiple Access (WCDMA), Long-term evolution (LTE, Long Term Evolution) system and other systems.

The system performs the division of the broadcast area in the location area within the control range of the base station controller, so that the paging request message received by the base station controller can be broadcasted in the corresponding broadcast area. In the embodiment of the present invention, the location will be determined by the system. The technical solution of the present invention is described by taking a broadcast area divided into VLANs as an example. In general, a location area includes all base transceiver stations under the control of a base station controller, and a location area will be divided into at least one VLAN area. In addition, the system will also transmit and receive to the base station controller, the Abis transmission network, and the base station. The station performs data configuration such that the Abis paging message generated according to the paging request message can be broadcast between the base station controller, the Abis transmission network, and the base transceiver station. Specifically, the system configures the correspondence between the location area code and the VLAN code on the base station controller, that is, the VLAN code mapping table, so that the base station controller can determine the area of the VLAN to be broadcast according to the location area code, and also needs to be in the base station. The mapping between the VLAN ID and the sending port number is configured on the controller to facilitate the broadcast of the Abis paging message from the designated port. In addition, the base station controller can also configure the VLAN service priority so that the Abis paging message can be sent according to the VLAN priority. The forwarding table of the VLAN is configured on the device (router or switch) in the Abis transmission network. After the device in the Abis transmission network receives the VLAN packet (Abis paging message) from the receiving port, it can determine the forwarding according to the forwarding table of the VLAN. The port sends the VLAN packet from the determined forwarding port. The base station transceiver station can configure the correspondence between the VLAN code and the receiving port to facilitate receiving the Abis paging message from the specific receiving port. It should be noted that, in the embodiment of the present invention, the configuration of the base station controller, the Abis transmission network, and the base transceiver station may be set according to specific needs, which is not limited herein.
