Patent ID: 8264999

Claim:
A method for realizing paging in a mobile switching center (MSC) pool, comprising: selecting, by an MSC server, a media gateway (MGW) from more than one MGW connected to a base station controller (BSC)/radio network controller (RNC), delivering a paging message of an international mobile station identity (IMSI) paging type to the selected MGW, wherein the selected MGW that receives the paging message further sends the paging message to the BSC/RNC, wherein a MGW that is connected to the BSC/RNC and does not receive the paging message receives a paging response message from the BSC/RNC that receives the paging message; and storing, by the MGW that is connected to the BSC/RNC and does not receive the paging message a corresponding relation between an IMSI carried in the paging message and the MSC server; and determining, by the MGW that is connected to the BSC/RNC and does not receive the paging message, the MSC server corresponding to the IMSI carried in the paging response message by looking up the corresponding relation between the IMSI carried in the paging response and the MSC server stored therein after receiving the paging response message sent by the BSC/RNC, and routing the received paging response message to the MSC server.
