The embodiments and the features in the embodiments can be combined with each other under the condition of no conflict, and the formed technical schemes are all within the protection scope of the application.
Example 1
The invention provides a communication method, please refer to fig. 1, the method is applied to a user terminal, comprising the following steps:
step S110: and initiating a call invitation to the network side.
The user sends the call invitation signaling of the session initiation protocol of the IP multimedia system to the network. The IP multimedia system, namely the IMS is a network structure, the IMS not only can realize the initial VoIP service, but also can manage network resources, user resources and application resources more effectively, thereby improving the intelligence of the network, and enabling users to cross various networks and use various terminals. Session initiation protocol (Session Initiation Protocol, SIP) is a multimedia communication protocol formulated by the internet engineering task force (Internet Engineering Task Force, IETF). SIP is a text-based application-layer control protocol for creating, modifying, and releasing sessions for one or more participants.
Step S120: after receiving the first response information fed back by the network side according to the call invitation, the network side sends the current video voice coding mode of the user side to the network side.
After receiving the call invitation sent by the user terminal, the network terminal can feed back the call invitation correspondingly and send first response information to the user terminal. And the user terminal sends the current video voice coding mode of the user terminal to Wang Luodan after receiving the first response information.
Step S130: and acquiring the current video voice coding mode of the network side.
The network side sends the current video and voice coding mode of the network side to the user side. When acquiring the current video and voice coding mode of the network side, the user side firstly acquires second response information sent by the network side according to the current video and voice coding mode of the user side, wherein the second response information comprises the current video and voice coding mode of the network side; and acquiring the current video voice coding mode of the network side according to the second response information.
Step S140: and receiving the redirection signaling sent by the network terminal.
Step S150: and carrying out network redirection according to the redirection signaling.
The redirection signaling includes a target network type, and the user terminal may redirect according to the target network type included in the redirection signaling. The user terminal can redirect to the 3G network through the network according to the redirection signaling. For example, the ue may receive signaling from the ue for handover of the uplink dedicated control channel to the common radio access network, i.e. redirection signaling, and then perform network redirection according to the redirection signaling.
Step S160: and if the hang-up signaling sent by the network end is not received after the network redirection is carried out according to the redirection signaling, establishing communication connection with the network end.
After the network redirection is carried out according to the redirection signaling, if the hanging-up signaling sent by the network side is not received, the network side and the user side are indicated to have the same video and voice coding mode, and communication connection can be carried out between the network side and the user side.
Step S170: if the network redirection is performed according to the redirection signaling, the hang-up signaling sent by the network end is received, the current video voice coding mode of the user end is replaced by the current video voice coding mode of the network end, and the step S110 is transferred.
After the network redirection is performed according to the redirection signaling, if the hang-up signaling sent by the network side is received, the network side is indicated to be different from the video voice coding mode of the user side, and the video voice coding mode supported by the network side is different from the video voice coding mode supported by the user side, so that communication connection between the network side and the user side cannot be performed, and the network side sends the hang-up signaling to the user side, so that a call between the user side and the network side is hung up.
In summary, the present application provides a communication method, which is applied to a user terminal, including: initiating a call invitation to a network terminal; after receiving first response information fed back by the network side according to the call invitation, sending a current video voice coding mode of the user side to the network side; acquiring a current video voice coding mode of the network side; receiving a redirection signaling sent by the network terminal; network redirection is carried out according to the redirection signaling; if the hang-up signaling sent by the network end is not received after the network redirection is carried out according to the redirection signaling, the communication connection with the network end is established; if the network redirection is carried out according to the redirection signaling, the hang-up signaling sent by the network terminal is received, the current video voice coding mode of the user terminal is replaced by the current video voice coding mode of the network terminal, and the step of initiating the call invitation to the network terminal is transferred. After the user terminal sends the call invitation to the network terminal, the network terminal feeds back according to the call invitation. And then the network side sends the current video voice coding mode of the network side to the user side according to the current video voice coding mode of the user side, so that when the user side receives the hang-up signaling sent by the network side, the current video voice coding mode of the user side is updated to be the video voice coding mode consistent with the current video voice coding mode of the network side, the user side is ensured not to hang up by the network side in subsequent calls, and the call stability is improved.
Example two
On the basis of the first embodiment, the present embodiment describes the method in the first embodiment by way of specific embodiments.
In order to ensure the normal call, after the current video voice coding mode of the network side is obtained, the method further comprises the following steps: transmitting third response information of the current video voice coding mode successfully received by the network terminal to the network terminal; and sending the voice session setting of the IP multimedia subsystem to the network terminal. So as to ensure normal conversation between the network end and the user end.
The current video voice coding mode of the user terminal comprises an EVS coding scheme or an AMR coding scheme, and the current video voice coding mode of the network terminal comprises the EVS coding scheme or the AMR coding scheme. The current video service has standard definition, high definition, super definition, 1080P and other technologies, and with the continuous development of the technologies, the video definition is also continuously enhanced. Voice traffic goes from NB (narrowband) communication in the 2G age to WB (wideband) communication currently in use by 3G and 4G for enhanced clarity. Voice services like video services, there are SWB (ultra wideband) and FWB (full wideband communication) after WB wideband communication, a speech coding technique which further evolves the speech coding technique we call the EVS coding scheme.
The enhanced speech service of the EVS coding scheme is an improvement of the call coding technology after the AMR-WB high-definition speech coding technology, so that the flexibility and the efficiency of coding are improved. Is defined by the 3GPPR12 version and is mainly applied to LTE and next generation communication systems. It has the following advantages: first, enhancing the quality and coding efficiency of NB narrowband and WB wideband; second, enhancing the voice quality of SWB ultra wideband and FWB full wideband; third, enhancing the quality of the mixed content and music in the telephony application; fourth, robust packet loss and delay jitter; fifth, ARM-WB is backward compatible. That is, the EVS coding scheme is an evolution in the AMR coding scheme, and the user terminal supports the EVS coding scheme. However, because the network in some places only supports the AMR coding scheme, the EVS coding scheme supported by the terminal is inconsistent with the AMR coding scheme, so that the video color ring service of the terminal cannot be used normally.
For example, if the current video and voice coding mode of the user terminal is the AMR coding scheme and the current video and voice coding mode of the network terminal is the AMR coding scheme, the user terminal receives the redirection signaling sent by the network terminal, and after the network redirection is performed according to the redirection signaling, does not receive the hang-up signaling sent by the network terminal, and the normal call between the network terminal and the user terminal is performed. If the current video voice coding mode of the user terminal is the EVS coding scheme and the current video voice coding mode of the network terminal is the AMR coding scheme, the user terminal receives the redirection signaling sent by the network terminal, and receives the hang-up signaling sent by the network terminal after the network redirection is carried out according to the redirection signaling. The user terminal changes the current video voice coding mode into an AMR coding scheme, and the current video voice coding mode of the user terminal is the same as the current video voice coding mode of the network terminal after the change, so that the user terminal can be ensured not to hang up in the process of sending a communication call to the network terminal by the user terminal next time.

step S260: the user performs network redirection according to the redirection signaling;

step S280: if the network redirection is performed according to the redirection signaling, the hang-up signaling sent by the network end is received, the current video voice coding mode of the user end is replaced by the current video voice coding mode of the network end, and the step S210 is transferred.
