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), the bearer setup request message to instruct the eNodeB to set up a voice bearer for user equipment;
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, the indication message to indicate that a voice over Internet Protocol IP multimedia subsystem (VoIMS) of the user equipment is unavailable;
sending, by the MME, a first location update request message to a home subscriber server (HSS) according to the bearer setup failure message, wherein the first location update request message is to notify the HSS that the VoIMS of the user equipment is unavailable;
after the sending, by the MME, the indication message to the user equipment;
receiving, by the MME, a second registration request message or a second combined registration request message that is sent by the user equipment; and
sending, by the MME, a second registration acceptance message or a second combined registration acceptance message to the user equipment, wherein the second registration acceptance message or the second combined registration acceptance message comprises second indication information to indicate that the VoIMS of the user equipment is available,after the sending, by the MME, the second registration acceptance message or the second combined registration acceptance message to the user equipment,sending, by the MME, a second location update request message to the HSS, wherein the second location update request message is to notify the HSS that the VoIMS of the user equipment is available.

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.
