Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a service recovery method, an apparatus, and a mobile terminal.
Background
When a Voice over LTE (VoLTE) terminal based on a multimedia system sends a Session Initiation Protocol (SIP) message to an SIP server in a network, the SIP server sometimes returns a response code in the form of "5 xx" to the VoLTE terminal because of excessive message processing load or in a maintenance phase or other reasons, which indicates that the SIP server is wrong, and at this time, the VoLTE service is interrupted. At this time, if the response code in the form of "5 xx" replied by the SIP server in the network carries the "Retry-After" header field, it indicates that the SIP server does not want the VoLTE terminal to send any SIP request message to the network within the time indicated by the "Retry-After" header field, and the VoLTE terminal will operate according to the instruction of the SIP server.
However, there may be a case where the response code in the form of "5 xx" does not carry the "Retry-After" header field, at this time, the VoLTE terminal needs to periodically send a heartbeat message to the SIP server of the network, and determines whether the network can send the SIP message according to whether the SIP server replies the response message, if the SIP server replies the response message, it indicates that the terminal can send the SIP message to the network, and if the SIP server does not reply the response message, it indicates that the network is in a busy or paralyzed state, and the terminal does not send the SIP message to the network.
In the process of implementing the invention, the inventor finds that at least the following technical problems exist in the prior art:
when recovering the VoLTE service, the VoLTE terminal needs to periodically send heartbeat messages to the SIP server, which may additionally increase network load.
