Description
Technical field
The present invention relates to the injection frequency continuous voice calls before wireless communication technology field more particularly to a kind of ring
Implementation method, device and mobile terminal.
Background technology
With the continuous development of mobile phone technique and the gradual intensification of 4G networks, the speech business based on 4G obtains considerable hair
Exhibition, the speech business based on 4G is a kind of IP data transmission technologies, and whole business can be all carried on 4G networks by it, no
2G/3G networks before need to relying on, so as to fulfill the unification of data and speech business on identical network；That is, pass through
The support of speech business based on 4G, we can not merely enjoy the data service of high-speed in 4G networks, additionally
Higher-quality voice, video calling can be carried out with it.
Injection frequency continuous voice call scheme is when the voice call based on 4G is switched to 2/3G circuit commutative fields, is made
Phone keeps a kind of continuous standard scheme.
Wherein, injection frequency continuous voice call scheme (the Single Radio Voice Call before ring
Continuity Before Ringing, bSRVCC) be injection frequency continuous voice call scheme one of which, bSRVCC
Technology switches, because network exists generally referred to as after terminal receives session progress message before receiving ALERTING message
The grouping system carrying for establishing evolution can be synchronized when sending session progress message to terminal, wherein, in the session progress message
It can indicate whether network supports bSRVCC to switch, when the network support bSRVCC switches, then after switching command is received
2/3G networks are switched to by bSRVCC to conversate, if the network does not support bSRVCC to switch, network switching failure.
But the session progress message is by TCP connection or UDP connections when being transmitted, it may be due to the signal of 4G networks
The reasons such as poor or network delay lead to terminal before session progress message is received, and first receive the switching command that network issues,
At this moment, terminal meeting default network does not support bSRVCC to handle.
In the implementation of the present invention, inventor has found at least to have the following technical problems in the prior art：
In the prior art, for the feelings that the switching command that network issues first is received before terminal receives session progress message
Condition can be defaulted as the network and not support bSRVCC, no matter whether real network supports can all occur during bSRVCC due to acquiescence
Network does not support the problem of terminal is without switching caused by bSRVCC, so as to phone call drop phenomenon occur.
