Description

Technical Field

[0001] The embodiments of the present application relate to the field of communication technology, and specifically to a communication method, device, electronic device, and computer-readable storage medium. Background Art

[0002] Real-Time Text (RTT) is a technology that allows users to send and receive text messages in real time during a call. Unlike traditional text messaging methods (such as SMS), RTT transmits text messages in real time while both parties are speaking, enabling seamless two-way communication. Therefore, RTT provides an effective communication tool for people with hearing impairments.

[0003] However, in actual network testing, it was found that due to differences in network configuration between different operators, RTT calls between some operators could not be established normally. However, there was an RTT text box on the terminal interface. Although the user could enter relevant text, the user on the other end could not receive the corresponding text content, which misled the user and seriously affected the user experience.

[0056] The following will be combined with the drawings in this application to clearly and completely describe the technical solutions in this application. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0057] Figure 1 FIG. 1 is a schematic diagram of the RTT call establishment process under normal circumstances provided by an embodiment of the present application. Figure 1 As shown, an RTT call is established between user equipment (UE) via a network. The network can be provided by the same operator or different operators. Under normal circumstances, UE1 and UE2 are registered with the IP Multimedia Subsystem (IMS) and have RTT capabilities. UE1 makes an RTT call to UE2, and the INVITE message sent by UE1 carries RTT-related media parameters, which may be (m=text 40010, a=sendrecv). 40010 is the text port number, representing the port used by UE1 to subsequently send and receive text RTP packets; sendrecv represents the Real-time Transport Protocol (text RTP) packets that can send and receive real-time text data. UE2 then receives the INVITE message sent by the network containing RTT-related media parameters (e.g., m=text 35520, a=sendrecv), and then negotiates the establishment of the RTT call between UE1 and UE2. If the text port number is 0, it means that text RTP packets cannot be sent or received.

[0058] Figure 2FIG. 1 is a schematic diagram of an RTT call establishment process under abnormal circumstances provided by an embodiment of the present application. Figure 2 As shown, it was found in the actual network test that when user UE1 of operator A made an RTT call to user UE2 of operator B, due to the compatibility problem in the interaction between operators A and B, although UE1 carried m=text XX (XX was not a 0 value) when sending to network A, UE2 received m=text 0 (text port number was 0) in the INVITE message sent by network B, that is, UE1 and UE2 were out of sync, which eventually led to UE1 displaying that the RTT call was established, but UE2 could not receive the text content sent by UE1, which misled users and seriously affected the user experience.

[0059] In order to solve the above technical problems, an embodiment of the present application provides a calling method. Figure 3 Although the steps are shown in a logical order, in some cases, the steps shown or described may be performed in a different order than shown in the accompanying drawings. Specifically, the calling method can be applied to a terminal, where the terminal may include but is not limited to one or more of a smartphone, a tablet computer, a laptop computer, a desktop computer, and an in-vehicle computer. The terminal may be the receiving device of the RTT call.

[0060] It should be noted that the order of description of the following embodiments does not limit the priority order of the embodiments.

[0061] according to Figure 3 The calling method shown in FIG. 1 includes at least steps S110 to S120, which are described in detail as follows:

[0062] In step S110, when an invitation message for a real-time text communication (RTT) call is received from an initiating device, a port number carried in the invitation message is obtained.

[0063] In step S120 , when the port number is a target port number indicating that a real-time transport protocol text RTP data packet cannot be sent or received, the call establishment with the initiating device is completed through a voice call.

[0064] The receiving and initiating devices are registered with the IMS, an IP (Internet Protocol)-based network architecture that provides users with rich multimedia services. Both the receiving and initiating devices must be registered with the IMS to communicate and access services.

[0065] An initiating device registered with the IMS can, based on the IMS network architecture and communication protocols, initiate diverse multimedia service requests, such as voice calls, video conferencing, and / or file transfers, to a receiving device. Receiving devices registered with the IMS can accurately receive multimedia information transmitted over complex network links from other IMS-registered devices (such as the initiating device). This allows efficient and smooth information exchange between initiating and receiving devices based on the IMS.

[0066] The receiving device closely monitors various signal fluctuations on the network channel. When the initiating device sends an RTT call invitation message to the receiving device, the receiving device receives it. The receiving device parses the RTT call invitation message and obtains the port number carried in the message. Based on this port number, the receiving device establishes a call with the initiating device.

[0067] The receiving device can determine whether the port number carried in the RTT call invitation message is the target port number. The target port number indicates that the real-time transport protocol text RTP data packet cannot be sent or received. In one embodiment, the target port number is 0.

[0068] The port number carried in the invitation message is the target port number. One possible scenario is that the initiating device is not actually initiating an RTT call to the receiving device, so the port number carried is the target port number. In this case, the receiving device can directly respond to the target port number to conduct a non-RTT call with the initiating device. Another possible scenario can be referred to Figure 2 The initiating device initiates an RTT call to the receiving device. The port number originally carried is not the target port number, but the port number for the RTT call (the port number is not 0). However, due to network incompatibility between different operators and other issues, the port number received by the receiving device is the target port number. At this time, if the receiving device directly completes the call establishment with the initiating device based on the target port number, then for the receiving device side, it is a non-RTT call, but for the initiating device side, it is an RTT call. Then, the text RTP data packet sent by the initiating device to the receiving device cannot be received by the receiving device, which will cause misunderstanding between the initiating device side and the receiving device side.

[0069] Therefore, if the receiving device determines that the port number carried in the initiating device's RTT call invitation message is the target port number indicating that it cannot send or receive text RTP packets, the receiving device can proactively complete the call with the initiating device through a voice call. In either case, normal communication between the initiating and receiving devices is guaranteed.

[0070] Using the technical solution of the embodiment of the present application, the initiating device sends an RTT call invitation message to the receiving device; upon receiving the RTT call invitation message from the initiating device, the receiving device can obtain the port number carried in the invitation message; if the port number is the target port number of a Real-time Transport Protocol (RTP) data packet indicating an inability to send or receive real-time text data, the call with the initiating device can be established as a voice call; upon receiving a response message from the receiving device requesting the establishment of a voice call, the initiating device completes the call with the receiving device as a voice call. This avoids the problem of the initiating device believing an RTT call has been established when the receiving device cannot actually receive the text, effectively improving the user's call experience.

[0071] Based on the above technical solution, as an embodiment, completing the establishment of a call with the initiating device through a voice call may include: downgrading the RTT call to a voice call; replying to the initiating device with a response message for establishing a voice call to complete the establishment of the voice call; wherein the response message carries the target port number.

[0072] Because the initiating device initiates an RTT call, the receiving device needs to first downgrade the RTT call to a voice call in order to complete the call establishment with the device through a voice call.

[0073] A voice call is a method of communicating between two parties in real time through the transmission of voice signals. Voice calls can convey information directly and quickly, allowing both parties to communicate instantly, just like face-to-face conversations, greatly improving communication efficiency.

[0074] like Figure 4 As shown, in order to let the initiating device know that the RTT call has been downgraded to a voice call, the receiving device can carry the target port number in the response message when replying to the initiating device's RTT call invitation message, so that the initiating device can know that the RTT call has been downgraded to a voice call based on the target port number carried in the response message, and thus conduct a voice call with the receiving device.

[0075] In one embodiment, the target port number may be included in the 183Session Progress response message sent back by the receiving device. The 183Session Progress response message indicates that the call is in progress and has made some progress, but has not yet been fully established or completed. It is an intermediate status message between the initial request and the final success or failure response during the call establishment process. The 183Session Progress response message may also include specific details about the call progress, such as the status of media negotiation, the determined encoding format, and possible call forwarding information. With this information, the initiating device can understand the current processing status of the receiving device and the direction of the call development.

[0076] By adopting the technical solution of the embodiment of the present application, the receiving device can inform the initiating device that the RTT call has been downgraded to a voice call by replying to the initiating device with a response message carrying the target port number, so as to realize a voice call between the initiating device and the receiving device, avoiding the problem that the initiating device mistakenly believes that an RTT call has been established but the actual receiving device cannot receive the text, and can effectively improve the user's call experience.

[0077] Based on the above technical solution, as an embodiment, upon receiving an invitation message for a real-time text communication (RTT) call from an initiating device, obtaining the port number carried in the invitation message may include: upon receiving the invitation message for the RTT call from the initiating device, starting a listener; and obtaining the port number carried in the invitation message based on the listener. The call method further includes: determining, based on the listener, whether the port number is the target port number.

[0078] The receiving device may set a listener, which is used to obtain and listen to the port number carried in the RTT call invitation message.

[0079] When the receiving device obtains the invitation message of the RTT call, the receiving device can start a listener, and can use the listener to parse the invitation message of the RTT call and obtain the port number carried in the invitation message of the RTT call.

[0080] Before determining whether to complete the call establishment with the initiating device as a voice call or an RTT call, the listener first determines whether the port number carried in the RTT call invitation message is the target port number. If the listener determines that the port number carried in the RTT call invitation message is the target port number, the receiving device completes the call establishment with the initiating device as a voice call. If the listener determines that the port number carried in the RTT call invitation message is not the target port number, the receiving device completes the call establishment with the initiating device as an RTT call.

[0081] By adopting the technical solution of the embodiment of the present application, the listener can determine whether the port number carried in the invitation message of the RTT call is the target port number, thereby helping the receiving device to determine whether to complete the call establishment with the initiating device through a voice call or an RTT call, thereby improving the user's call experience.

[0082] Based on the above technical solution, as an embodiment, the call method may further include: when the port number is not the target port number, completing the call establishment with the initiating device through RTT call.

[0083] The receiving device determines that the port number carried in the RTT call invitation message is not the target port number, proving that there is no compatibility issue and that the receiving device and the initiating device can send and receive Real-time Transport Protocol (RTP) data packets. Therefore, the receiving device can directly establish the call with the initiating device via RTT.

[0084] Optionally, the receiving device may not carry the port number in its response message to the initiating device, or it may carry the port number carried in the invitation message for the RTT call. If the port number carried in the invitation message for the RTT call is to be carried, the port number carried in the invitation message for the RTT call may be carried in the 183 Session Progress response message.

[0085] By adopting the technical solution of the embodiment of the present application, when the port number is not the target port number, the receiving device can complete the RTT call establishment with the initiating device, thereby conducting an RTT call with the initiating device.

[0086] An embodiment of the present application provides a method for making a call. Figure 5 Although the steps are shown in a logical order, in some cases, the steps shown or described may be performed in a different order than shown in the accompanying drawings. Specifically, the calling method can be applied to a terminal, where the terminal may include but is not limited to one or more of a smartphone, a tablet computer, a laptop computer, a desktop computer, and an in-vehicle computer. The terminal may be the initiator of the RTT call.

[0087] according to Figure 5 The calling method shown in FIG. 1 includes at least steps S210 to S220, which are described in detail as follows:

[0088] In step S210, an RTT call invitation message is sent to a receiving device.

[0089] In step S220, upon receiving a response message for establishing a voice call from the receiving device, the call establishment with the receiving device is completed through a voice call.

[0090] The response message is sent by the receiving device when the port number carried in the invitation message is a target port number indicating that the device cannot send or receive text RTP data packets.

[0091] The receiving device and the initiating device are both registered with the IMS. Based on the IMS network architecture and communication protocols, the initiating device can initiate a variety of multimedia service requests, such as voice calls, video conferencing, and / or file transfers, to the receiving device. The receiving device registered with the IMS can accurately receive multimedia information transmitted from other IMS-registered devices (such as the initiating device) over complex network links. This allows the initiating and receiving devices to achieve efficient and smooth information exchange based on the IMS.

[0092] The initiating device sends an RTT call invitation message to the receiving device. The receiving device then parses the message to obtain the port number carried in the message. Based on this port number, the receiving device establishes a call with the initiating device.

[0093] The receiving device can determine whether the port number carried in the RTT call invitation message is the target port number. The target port number indicates that the real-time transport protocol text RTP data packet cannot be sent or received. In one embodiment, the target port number is 0.

[0094] If the receiving device determines that the port number carried in the initiating device's RTT call invitation message is the target port number indicating inability to send or receive text RTP packets, it can proactively establish the call with the initiating device through a voice call. Specifically, the receiving device sends a voice call establishment response message to the initiating device, which carries the target port number indicating inability to send or receive text RTP packets.

[0095] The remaining technical details of the embodiments of this application can be referred to above and will not be repeated here.

[0096] Using the technical solution of the embodiment of the present application, the initiating device sends an RTT call invitation message to the receiving device; upon receiving the RTT call invitation message from the initiating device, the receiving device can obtain the port number carried in the invitation message; if the port number is the target port number of a Real-time Transport Protocol (RTP) data packet indicating an inability to send or receive real-time text data, the call with the initiating device can be established as a voice call; upon receiving a response message from the receiving device requesting the establishment of a voice call, the initiating device completes the call with the receiving device as a voice call. This avoids the problem of the initiating device believing an RTT call has been established when the receiving device cannot actually receive the text, effectively improving the user's call experience.
