COMMUNICATION METHOD, DEVICE, AND SYSTEM
First Claim
1. A communication method, comprising:
- sending, by a mobility management entity (MME), a bearer setup request message to an evolved NodeB (eNodeB), wherein the bearer setup request message is used to instruct the eNodeB to set up a voice bearer for user equipment; and
when the MME receives a bearer setup failure message sent by the eNodeB in response to the bearer setup request message,sending, by the MME, an indication message to the user equipment, wherein the indication message is used to indicate that a voice over Internet Protocol IP multimedia subsystem (VoIMS) of the user equipment is unavailable.

Abstract
A communication method includes: sending, by an MME, a bearer setup request message to an eNodeB, where the bearer setup request message is used to instruct the eNodeB to set up a voice bearer for user equipment; and when the MME receives a bearer setup failure message sent by the eNodeB in response to the bearer setup request message, sending, by the MME, an indication message to the user equipment, where the indication message is used to indicate that a voice over VoIMS of the user equipment is unavailable. When setup of a voice bearer of a VoLTE call fails, the user equipment is notified that a VoLTE is unavailable, so that the user equipment can be prevented from continuing attempting to initiate the VoLTE call and exacerbating cell congestion.

12. A mobility management entity, comprising:
-
a transmitter, configured to send a bearer setup request message to an evolved NodeB (eNodeB), wherein the bearer setup request message is used to instruct the eNodeB to set up a voice bearer for user equipment; and a receiver, configured to receive a bearer setup failure message sent by the eNodeB in response to the bearer setup request message;
whereinthe transmitter is further configured to send an indication message to the user equipment, wherein the indication message is used to indicate that a voice over Internet Protocol IP multimedia subsystem (VoIMS) of the user equipment is unavailable. - View Dependent Claims (13, 14, 15, 16, 17, 18)
