Abstract
The present invention discloses a voice resource saving method, including: an MME sends a notification message to an eNodeB, which is used to instruct the eNodeB not to hand over, for a non-voice service, a UE from a LTE network to a CS domain of a 2G or a 3G network. Or, when an MSC determines that the circuit domain service is a non-voice service, the MSC sends a bearer release message to a base station to instruct the base station to release the voice resource. According to the the present invention, during implementation of a non-voice service, a handover of UE from an LTE network to a CS domain of a 2G or 3G network may not be triggered, or a voice resource reserved in the CS domain of the 2G or 3G network is released.
