  • Patent number: 9924563
    Abstract: The disclosure provides a method for realizing a Mobile Switch Center (MSC) pool, a system for realizing an MSC pool and a Media Gateway (MGW). The method for realizing an MSC pool includes: connecting with a Base Station Controllers (BSC)/Radio Network Controller (RNC), by a Media Gateway (MGW) through the use of a common signaling point; and upon receipt of a message whose destination signaling point is the common signaling point from the BSC/RNC, determining, by the MGW, a destination MSC server of the message according to ID information carried in the message, and sending the received message to the destination MSC server. According to the present invention, the networking scheme for an MSC pool may be implemented without upgrading any BSC/RNC. The flexibility of the networking scheme for mobile communication systems may be improved, and the traffic load of the subscribers may be shared.

  • Patent number: 8264999
    Abstract: A method for realizing paging in a mobile switching center (MSC) pool includes the following steps. An MSC server selects a media gateway (MGW) from more than one MGW connected to a base station controller (BSC)/radio network controller (RNC), delivers a paging message of an international mobile station identity (IMSI) paging type to the selected MGW, and stores a corresponding relation between an IMSI carried in the paging message and the MSC server in the MGW which is connected to the BSC/RNC and does not receive the paging message. The MGW that does not receive the paging message receives a paging response message sent by the BSC/RNC, determines an MSC server corresponding to an IMSI carried in the paging response message by looking up the corresponding relation between the IMSI and the MSC server stored therein, and routes the received paging response message to the corresponding MSC server. Several other methods and devices for realizing paging are also provided.
