[0052] To make the objects, technical solutions, and advantages of the present application clearer, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely intended to explain the present application and are not intended to limit the present application.

[0053] FIG. 1 is a diagram of an application scenario of a method for processing a data channel according to an embodiment. As shown in FIG. 1, data transmission is performed between a terminal 100, a target application 200, and a chip 300 through a network, a software module is a function of the terminal 100, and can be implemented through a middleware (such as an SDK) or a native operating system, which can be an Android system, a Hongmeng system, an IOS system, and the like.

[0054] In some embodiments, the terminal 100 can be a wireless terminal, which can refer to a device that provides voice and / or other data connectivity to a user, or a hand-held device having a wireless connection function, or other processing device connected to a wireless modem. The wireless terminal can communicate with one or more core networks via a Radio Access Network (RAN), and can be a mobile terminal, such as a mobile telephone (or "cellular" telephone) and a computer with a mobile termination that can be, for example, portable, pocket, hand-held, computer-included, or car-mounted, and exchanges language and / or data with a radio access network. The wireless terminal can also be referred to as a system, a subscriber unit, a subscriber station, a mobile station, a mobile, a remote station, a remote terminal, an access terminal, a user terminal, a user agent, a user device, or user equipment, without limitation.

[0055] In the prior art, during 5G enhanced call, when the DC application has successfully established DC with the opposite end, after the DC application is closed but the DC application does not call the interface of tearing down DC, if the user starts the application again, the software module will re-call the interface of creating DC to request the chip to establish DC, which will cause the chip to create multiple DC objects for the same DC application, and the SCTP link needs to be re-established through signaling negotiation. The chip repeatedly creates DC objects for the same DC application, which will cause waste of network and chip resources, and repeatedly creating DC will also increase the end-to-end second-level delay.

[0056] Based on the above-mentioned prior art, the embodiment of the present application provides a data channel processing method, which queries whether there is a cached data channel in the cache function to avoid repeatedly establishing multiple data channel objects for the same target application, thereby saving communication resources.

[0057] It should be noted that the beneficial effects or technical problems solved by the embodiments of the present application are not limited to this, but also other implicit or related problems, which can be referred to the description of the following embodiments.

[0058] Before introducing the specific embodiments of the present application, the professional terms involved in the present application are explained:

[0059] DC (Data Channel): is the data channel defined by 3GPP IMS audio and video communication architecture, by establishing one or more data channels parallel to audio and video transmission in IMS session, any type of data can be transmitted, so as to realize real-time interaction in audio and video call, the data channel can include BDC and ADC; BDC (Bootstrap Data Channel) is established between the terminal and the IMS network, which is used for the terminal to obtain the data channel application list from the IMS network and download the required data channel application. ADC (Application Data Channel) is established between the terminal and the IMS network or the terminal, which is used for transmitting application data of the data channel application.

[0060] SCTP (Stream Control Transmission Protocol): SCTP protocol is a computer network communication protocol used in the transport layer of Internet Protocol Suite. It is a connection-oriented network protocol used to transmit multiple data streams between endpoints. When transmitting data in IMS Data Channel, the SCTP protocol carries the protocol data transmission of the application layer.

[0061] The technical solutions of the present application and how the technical solutions of the present application solve the above technical problems will be described in detail below with specific examples. The following specific examples can be combined with each other, and the same or similar concepts or processes may not be described again in some examples. The embodiments of the present application will be described below with reference to the drawings.

[0062] In one embodiment, as shown in FIG. 2, a data channel processing method is provided, and the method is applied to the software module in FIG. 1 as an example, including the following steps:

[0063] Step 202, when the target application meets the target restart condition, the data channel object corresponding to the target application is queried through the cache function, and the query result is obtained.

[0064] In some embodiments, the target restart condition is that the target application successfully establishes a data channel with a peer, and the target application is restarted after being closed in the same call; the cache function can be a function of the terminal device, and can be implemented through a middleware or a native operating system. The middleware can be an SDK, and the native operating system can be an Android operating system, a Harmony operating system, an iOS operating system, or the like. The target restart condition can be that the target application has successfully established at least one data channel with a terminal, the software module caches data channel objects corresponding to the target application, and the target application is restarted after being closed during the same call. The target application can be a specific application, for example, an application that has successfully established a data channel and has been closed and restarted. That is, the target restart condition can be that the target application successfully establishes a data channel with a peer, and the target application is restarted after being closed in a call. The data channel can be a data channel established between terminals or a data channel established between a terminal and a network. The DC application can run on a terminal device, and the software module can be a middleware or an operating system of the terminal. The middleware can be an SDK, and the operating system of the terminal can be an Android operating system, a Harmony operating system, an iOS operating system, or the like.

[0065] In some embodiments, when the software module determines that the target application meets the target restart condition, the software module can query whether the data channel object corresponding to the target application has been cached through the cache function, and obtain a query result. The query result can be that the cached data channel object corresponding to the target application is queried, or the query result can also be that the data channel object corresponding to the target application is not queried. In an example, the data channel object corresponding to the target application can be a data channel object of the target application cached by the software module after the target application successfully establishes a data channel with a terminal.

[0066] In some embodiments, after the target application successfully establishes at least one data channel DC with a peer, the software module can cache all DC objects of the target application. The software module can also cache all DC objects of each application. The target application can be closed in response to a user-triggered application closing instruction, and when the target application is restarted, the software module can query whether the DC object of the target application has been cached through the cache function, and obtain a query result.

[0067] In step 204, the target application is restarted based on the data channel corresponding to the query result.

[0068] In some embodiments, the query result can be that the DC object of the target application has been cached, the corresponding data channel can be a data channel that has been established previously, or the query result can be that the DC object of the target application has not been cached, and the corresponding data channel can be a newly created data channel.

[0069] In some embodiments, the software module can obtain a query result of the data channel corresponding to the target application through the cache function, and restart the target application based on the data channel corresponding to the query result. In one example, the query result can not query the data channel corresponding to the target application, and the software module can re-call the data channel creation interface to recreate the data channel corresponding to the target application. In another example, the query result can be that the data channel corresponding to the target application is queried, which indicates that the data channel previously established by the target application has not been cleared, i.e., the data channel previously established by the target application still exists, and the target application can be restarted based on the existing data channel.

[0070] In the above method for processing the data channel, when the target application satisfies the target restart condition, the cache function is used to query the data channel object corresponding to the target application to obtain a query result. The target restart condition is that the target application successfully establishes a data channel with a peer, and the target application is restarted after being closed in the same call. The target application is restarted based on the data channel corresponding to the query result. By using the method, multiple data channel objects can be avoided for the same application, communication resources can be saved, and end-to-end latency can be reduced.

[0071] In one embodiment, the query result is that the data channel object of the target application is not queried, specifically, the query result indicates that the data channel object corresponding to the target application has not been cached, i.e., the data channel corresponding to the target application has been cleared, which can also be understood as a cache miss. Accordingly, restarting the target application based on the data channel corresponding to the query result can include:

[0072] Sending a data channel establishment request to the chip through the data channel creation interface, so that the chip and the network re-negotiate to establish a data channel, and restarting the target application based on the data channel.

[0073] In some embodiments, the data channel creation interface can be an interface for creating a DC, and the data channel establishment request is used to request the chip to establish a data channel for the target application.

[0074] In some embodiments, when the software module does not query the data channel object of the target application, the software module can re-call the data channel creation interface to send a data channel establishment request to the chip through the data channel creation interface, the data channel establishment request being used to make the chip re-establish a data channel for the target application; after receiving the data channel establishment request, the chip can re-negotiate with the network based on the data channel establishment request to establish a data channel for the target application. After successfully establishing the data channel of the target application, the target application can be restarted.

[0075] In one example, before the data channel object corresponding to the target application is queried, the processing method of the data channel can further include: after the target application successfully establishes at least one data channel DC with the opposite end, the software module can cache all DC objects of the target application; the software module can also cache all DC objects of each application; the target application can be closed in response to an application closing instruction triggered by the user, the application closing instruction being an instruction triggered by the user to close the target application, and whether the data channel is closed can be determined based on the business logic; when it is determined based on the business logic that the data channel of the target application needs to be closed, the software module can call an interface for closing the DC to send a closing event to the chip, and after receiving the closing event, the chip can remove the data channel associated with the target application based on the received closing event, that is, remove the data channel of the target application, and generate a data channel closing notification message (i.e., a data channel removal notification message), and the chip can return the data channel closing notification message to the software module, and the software module can clear the data channel object corresponding to the target application that has been cached locally after receiving the data channel closing notification message. Based on this, when the software module subsequently determines that the target application meets the target restart condition, the query result can be that the data channel object corresponding to the target application is not queried.

[0076] In one example, the data channel closing notification message returned by the chip can carry identification information of the target application, and the software module can clear the data channel object corresponding to the identification information of the target application based on the identification information of the target application in the data channel closing notification message.

[0077] In some embodiments, when it is determined based on the business logic that the data channel of the target application does not need to be closed, that is, the interface for closing the DC is not called, the software module does not send a data channel closing notification message to the chip, and the chip is not aware.

[0078] In the embodiment, the data channel of the target application can be timely removed, and the data channel corresponding to the target application can be timely cleared, so as to avoid that the chip bears too many data channels for the same application, and also avoid that the software module locally stores too many data channel objects corresponding to the target application, thereby improving the utilization of the communication resources of the chip and the utilization of the resources of the terminal.

[0079] In one embodiment, the query result is a data channel object of the target application. Specifically, the query result indicates that the data channel previously established by the target application is not cleared, that is, the data channel previously established by the target application still exists, and at this time, the target application can be restarted based on the existing data channel. Correspondingly, based on the data channel corresponding to the query result, restarting the target application can include:

[0080] returning a notification message that the data channel has been successfully created to the target application, so that the target application determines that the data channel of the target application has been successfully created based on the notification message, and restarts based on the data channel.

[0081] In some embodiments, the notification message is used to instruct the target application that the software module locally has cached the data channel object corresponding to the target application, that is, the data channel of the target application is not cleared. The notification message can be a notification message that the data channel has been successfully created, and can make the target application receiving the notification message determine that the data channel corresponding to the target application has been successfully created.

[0082] In some embodiments, the software module can generate a notification message and send the notification message to the target application after determining that the data channel corresponding to the target application is cached, that is, the data channel of the target application is not cleared. After receiving the notification message, the target application can determine that the data channel of the target application exists, and the target application can be directly restarted.

[0083] In the embodiment, whether the data channel of the target application exists can be queried by querying whether the data channel object is cached before creating the data channel corresponding to the target application, so as to avoid that the chip repeatedly creates data channels for the same application, avoid waste of chip resources, and also avoid that the end-to-end time delay increases due to repeated creation of data channels.

[0084] In one embodiment, as shown in FIG. 3, the data channel processing method further includes:

[0085] Step 302: after the target application establishes a data channel with the terminal, caching a data channel object corresponding to the target application.

[0086] In some embodiments, the data channel object comprises a target capability; the target capability comprises one or more of sending data, closing the DC, obtaining a DC label, obtaining a stream id of the SCTP connection, and obtaining a call ID, the DC label being used to identify different data channels.

[0087] In some embodiments, after the target application successfully establishes at least one data channel with the peer terminal, the software module can cache all DC objects of the target application; in some embodiments, the software module can also cache all DC objects of each application. The target capability comprises one or more of sending data, closing the DC, obtaining a DC label, the label being an attribute of the DC data channel and being used to mark different DC data channels, obtaining a stream id, the stream id being a substream id of the SCTP connection, and obtaining a call ID.

[0088] Step 304, when the target application is closed and the interface for closing the data channel is called, a closing event is sent to the chip to make the chip remove the data channel corresponding to the target application and return a data channel closing notification message to the software module; the data channel closing notification message is received and the data channel object corresponding to the target application is cleared based on the data channel closing notification message.

[0089] In some embodiments, the target application can be closed in response to a user-triggered application closing instruction, which can be a user-triggered instruction for closing the target application, and whether the data channel is closed can be determined based on the business logic; when it is determined based on the business logic that the data channel of the target application needs to be closed, the software module can call the interface for closing the DC, send a closing event to the chip, and the chip can remove the data channel associated with the target application based on the received closing event, i.e., remove the data channel of the target application, and generate a data channel closing notification message (i.e., a data channel removal notification message), and the chip can return the data channel closing notification message to the software module.

[0090] After receiving the data channel closing notification message, the software module can clear the data channel object corresponding to the target application that has been cached locally. Based on this, when the software module subsequently determines that the target application meets the target restart condition, the query result can be that the data channel object corresponding to the target application is not found.

[0091] Step 306, when the target application is closed and the interface for closing the data channel is not called, no closing event is transmitted to the chip to make the chip have no awareness.

[0092] In some embodiments, if the interface for closing the DC is not invoked, the terminal has no special operation, the chip has no perception, and the upper application is closed; if the interface for closing the DC is not invoked, the software module does not deliver the closing event to the chip, the chip has no perception, and subsequent operations are processed by the software module.

[0093] In the embodiment, the data channel of the target application can be timely removed, and the data channel corresponding to the target application can be timely cleared, so that the chip is prevented from bearing too many data channels for the same application, and the software module is prevented from locally storing too many data channel objects corresponding to the target application, thereby improving the utilization rate of the communication resources of the chip and the utilization rate of the resources of the terminal.

[0094] In one embodiment, as shown in FIG. 4, the method for processing the data channel further includes:

[0095] In step 402, a calling request sent by a target application is received, and the calling request is used to create a data channel.

[0096] In some embodiments, in a case where the target application has successfully established a data channel with a peer, the software module buffers all data channel objects of each application; after a user triggers a function for closing the target application provided by the software module, the target application can be closed; when the user starts the target application again, the target application calls an interface for creating a data channel through the software module to request the chip to reestablish a data channel; that is, the target application can send a calling request to the software module, the calling request is used to call the interface for creating the data channel, and the chip is requested to re-create a DC through the interface for creating the data channel. Based on this, the software module can determine that the target application satisfies a target restart condition after receiving the calling request sent by the target application, and the software module can query whether the data channel object of the target application has been buffered through a buffering function. The calling request is a request initiated by the DC application for creating a data channel.

[0097] In the embodiment, the timeliness of querying the buffered object can be improved.

[0098] In one embodiment, FIG. 5 provides a flowchart of a method for processing a data channel. As shown in FIG. 5, the method includes the following steps:

[0099] In step 1, after an application (a target application) successfully establishes at least one DC with a peer, the software module buffers all DC objects of all applications, and each DC object has a target capability.

[0100] In step 2, a user triggers a function for closing a specific application provided by the software module, and whether to invoke the interface for closing the DC can be determined by business logic. Specifically, the user closes the specific application, and whether the application triggers the interface for closing the DC is determined by business logic.

[0101] Step 3.a, the interface for closing the DC is called by the software module, then the chip synchronously closes the event, triggers the chip to remove the DC associated with the specific application; specifically, if the interface for closing the DC is called, the software module needs to pass the closing event to the chip, then the chip removes the DC associated with the specific application and needs to notify the software module, and the software module clears the DC object of the specific application after receiving the notification that the DC is closed from the chip.

[0102] Step 3.b, if the interface for closing the DC is not called, the terminal has no special operation, the chip has no perception, and the upper application is closed; specifically, if the interface for closing the DC is not called, the software module does not pass the closing event to the chip, then the chip has no perception, and the subsequent operation is processed by the software module.

[0103] Step 4, when the user starts the same specific application again, the application reuses the interface for creating the DC to request the chip to reestablish the DC; specifically, when the same specific application (target application) is restarted, the software module queries whether the DC object of the specific application has been cached in the cache function.

[0104] Step 5.a, the terminal and the network perform signaling renegotiation, and reestablish the DC for the specific application.

[0105] Step 5.b, the software module returns the cached DC object to the specific application, and does not need to notify the chip.

[0106] Step 6, the same specific application is successfully restarted and normally used.

[0107] The data channel processing method provided in the embodiment can solve the problem of waste or even saturation of chip and network resources caused by the user restarting the same application during a call.

[0108] In one embodiment, the target application can be an application deployed on the terminal or an application deployed on an application server, which can be determined based on an actual application scenario; each target application can establish multiple data channels with a peer, and each data channel is configured with a data channel object corresponding to the data channel, and the data channel and the data channel object correspond to each other. The interface for closing the DC in the above embodiment can be an interface between the target application and the software module. The target application closing instruction triggered by the user (the closing option of the specific application closed by the user) can be provided by the target application or by the software module. The operation of restarting the target application can be triggered by the user or by the application server; the software module can be implemented through an operating system such as Android, Hongmeng, IOS, or can be implemented by middleware (SDK).

[0109] The data channel processing method provided in the embodiment can realize the DC cache function in a software module, realize chip non-perception on the premise of guaranteeing user experience, thereby saving end-to-end resources and reducing end-to-end delay. In the data channel processing method provided in the embodiment, after the application and the peer successfully establish at least one DC, the software module caches all DC objects of all applications, and each DC object contains a series of necessary attributes. When the same specific application is restarted, the software module queries whether the DC object of the specific application has been cached in the cache function. Caching all DC objects of all applications can ensure that the query result of querying the data channel object corresponding to the target application through the cache function in the subsequent embodiment is accurate.

[0110] In the data channel processing method provided in the embodiment, whether the application triggers the interface for calling the DC to be closed is determined by the business logic. The application can determine whether to call the interface for closing the DC according to actual needs. Only when the target application calls the interface, the underlying chip will remove the DC. If the target application does not call the interface, only the software module will perform corresponding processing, without the need to reestablish the SCTP link, thereby avoiding end-to-end delay.

[0111] In the data channel processing method provided in the embodiment, the software module returns the cached DC object to the specific application. Returning the cached DC object by the software module can shield the perception of the chip, without the need for re-signaling negotiation between the end and the network.
