VOICE RESOURCE SAVING METHOD, DEVICE, AND SYSTEM

摘要

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.

主权项

1. A voice resource saving method, comprising:
receiving, by a mobility management entity (MME) from a mobile switching center (MSC), a first paging request message that is used to page a user equipment (UE), wherein the first paging request message comprises first indication information indicating a non-voice service; and sending, by the MME, a notification message to an evolved NodeB (eNodeB) in response to the first paging request message, wherein the notification message is used to instruct the eNodeB not to hand over, for the non-voice service, the UE from a Long Term Evolution (LTE) network to a circuit switched (CS) domain of a second generation (2G) or a third generation (3G) network.
