Problems solved by technology

[0036] In the specific implementation process of the terminal, it is necessary to consider whether the precondition process is required during the upgrade process. If the precondition process is not used, it may happen that the user has answered the call but the resources are not ready, resulting in a poor user experience, and there is no related processing process, such as : What to do if the user does not answer, and what to do if the user refuses to answer
It can be seen that there will be differences in the specific implementation of the terminal, which will lead to problems in intercommunication.

Embodiment 1

[0069] In order to solve the foregoing technical problems, an embodiment of the present invention provides a method for converting an audio call into a video call, which is applied to a terminal, and the functions implemented by the method can be realized by calling a program code by a processor in the terminal. Of course, the program The code can be stored in a computer storage medium. It can be seen that the electronic device includes at least a processor and a storage medium.

[0070] Figure 1D It is a schematic diagram of the implementation flow of a method for converting an audio call into a video call according to an embodiment of the present invention, as shown in Figure 1D As shown, the method includes:

[0071] Step S101, the called terminal sends a first request message to the network side, and the first request message is used to request to upgrade the audio call to the video call;

[0072] Wherein, in addition to audio media description, the first request messa...

Embodiment 2

[0086] In order to avoid poor user experience and intercommunication between terminals, an embodiment of the present invention proposes a method for converting an audio call to a video call. In this embodiment, if the user does not receive the upgrade within a specified time, the timer of the called UE expires. figure 2 It is a schematic diagram of the implementation flow of the method for converting an audio call to a video call in Embodiment 2 of the present invention, as shown in figure 2 As shown, the method includes:

[0087] Step 1-14, UE1 (calling UE) initiates an audio call, uses the precondition process to complete the SDP negotiation, and UE2 (called UE) answers;

[0088] Step 15, UE 2 initiates a first request message, and the first request message is used to request an audio call to be upgraded to a video call (referred to as an upgrade request);

[0089] Here, in addition to including the audio media description, the first request message also needs to add a vi...

Embodiment 3

[0114] In order to avoid poor user experience and intercommunication between terminals, an embodiment of the present invention proposes a method for converting an audio call to a video call. In this embodiment, if the user does not receive the upgrade within a specified time, the timer of the calling UE expires. image 3 It is a schematic diagram of the implementation flow of the method for converting an audio call to a video call in Embodiment 3 of the present invention, as shown in image 3 As shown, the method includes:

[0115] Steps 1-14, UE1 (calling user equipment) initiates an audio call, uses the precondition process to complete SDP negotiation, and UE2 (called user equipment) answers;

[0116] Step 15, the UE2 user initiates an audio upgrade video call request, such as initiating a re-invite (re-invite) request message;

[0117] Here, the re-invite request message includes audio media description and added video media description (new additional media descriptions);...

Abstract

The invention discloses a method and apparatus for converting an audio call into a video call. The method includes that a terminal sends a first request message, the first request message being used for requesting the upgrade of an audio call into a video call, the first request message including an audio media description and a video media description; a called terminal receives a first reply message sent by a network side, the first reply message being used for indicating media resource negotiation for initiating the audio call and the video call; if the terminal resource reservation succeeds, the terminal sends a first update message to the network side based on the first reply message, the first update message being used for indicating that the local resource reservation succeeds.

Description

technical field [0001] The invention relates to audio and video call conversion technology, in particular to a method and equipment for converting an audio call to a video call. Background technique [0002] With the advent of large-scale commercial use of Long Term Evolution (LTE) networks, many operators adopt voice services (Voice over LTE, VoLTE) based on Internet Protocol (IP) Multimedia Subsystem (IP Multimedia Subsystem, IMS) as its voice solutions. IMS has become the core network standard architecture in the all-IP era because it supports multiple access and rich multimedia services. It is determined as a standard architecture for mobile voice by the 3rd Generation Partnership Project (3rd Generation Partnership Project, 3GPP) and the common concern and rights of global mobile operators (GSMA). VoLTE is an IP data transmission technology that does not require the 2nd-Generation wireless telephone technology (2G) or the 3rd-Generation wireless telephone technology (...
