In user call environments based on IMS data channels (DC), DC capabilities cannot be used in existing multi-party conversation scenarios. Summary of the Invention

[0081] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0082] See Figure 1 , Figure 1 This is a flowchart of a multi-party communication method provided in an embodiment of the present invention, used for a first terminal, such as... Figure 1 As shown, the method includes the following steps:

[0083] Step 101: Establish multi-party sessions and multi-party bootstrap data channels with M first target terminals. Here, M is an integer and M > 1. The multi-party bootstrap data channels are controlled by the same target data channel media function, and are used by the first terminals and N second target terminals to acquire the target applications corresponding to the target data channel media function. The N second target terminals are determined from the M first target terminals, where N is an integer and 0 < N ≤ M.

[0084] Step 102: Based on multiple Bootstrap data channels, obtain the target application from the media function of the target data channel.

[0085] Step 103: Within the target application, establish a multi-party application data channel with N second target terminals, and communicate with the N second target terminals based on the multi-party application data channel.

[0086] In related technologies, establishing a Data Center (DC) for IMS audio and video calls involves two steps: Step 1, establishing a Bootstrap Data Channel (BDC) between the two terminals (User Equipment, UE) for both parties to obtain applications under the corresponding media functions from the network; Step 2, establishing an Application Data Channel (ADC) between the two terminals for communication within the application. The aforementioned technologies typically do not consider multi-party communication scenarios involving three or more parties carrying a DC.

[0087] In this embodiment of the invention, a first terminal initiates multi-party communication. The first terminal establishes a Bootstrap data channel controlled by the same target data channel media (DCM) with at least two first target terminals, thereby enabling the establishment of a multi-party Bootstrap data channel among at least three terminals and extending the communication scenario carrying data channels to a multi-party communication scenario. The first terminal and at least two first target terminals can obtain the target application corresponding to the target data channel media function on the network based on the multi-party Bootstrap data channel. Subsequently, according to business needs, the first terminal can determine one or more second target terminals among the first target terminals for specific communication. If both the first terminal and the second target terminals have obtained the target application, a multi-party Application data channel can be established within the target application to achieve fully connected point-to-point communication based on the target application.

[0088] In an optional implementation, step 101 includes:

[0089] While maintaining the established sessions, M two-way sessions are sequentially established with each of the M first target terminals, and M first two-way Bootstrap data channels are established with each of the M first target terminals.

[0090] Once all M bilateral sessions have been established, a multi-party session is initiated, and if the M first-party Bootstrap data channels are controlled by the same target data channel media function, the M first-target terminals are invited to join the multi-party session.

[0091] In this embodiment, after establishing a two-way session with a first target terminal and establishing a corresponding first two-way Bootstrap data channel, the first terminal can, while maintaining the current session, establish another two-way session with the next first target terminal and establish a corresponding first two-way Bootstrap data channel. In other words, the first terminal can establish and maintain a two-way session with each of the M first target terminals and establish a corresponding first two-way Bootstrap data channel. If all of the above-mentioned multiple first two-way Bootstrap data channels are controlled by the same target data channel media function, it indicates that both the first terminal and the M first target terminals can use the target data channel media function and can obtain the target application corresponding to the target data channel media function from the network. At this time, a multi-party Bootstrap data channel based on the target data channel media function control is established between the first terminal and the M first target terminals.

[0092] For ease of understanding, this implementation uses an M=2 scenario, with the second and third target terminals as an example: The first terminal initiates a call carrying the Bootstrap data channel to the second terminal, establishing a first session. After the second terminal answers, Bootstrap data channel 1 is established between the first and second terminals. It should be noted that the specific implementation process of the above steps can be found in relevant technical descriptions and will not be elaborated here. While the first session is on hold, the first terminal then initiates a call carrying the Bootstrap data channel to the third terminal, establishing a second session. After the third terminal answers, Bootstrap data channel 2 is established between the first and third terminals. Again, the specific implementation process of the above steps can be found in relevant technical descriptions and will not be elaborated here. It is understood that both Bootstrap data channel 1 and Bootstrap data channel 2 are the first two-way Bootstrap data channels described above.

[0093] After all bilateral sessions are established, the first terminal can initiate a multi-party session and obtain information on M bilateral Bootstrap data channels to determine whether these M channels are controlled by the same DCM. This includes two scenarios:

[0094] Scenario 1: The M first-party Bootstrap data channels are controlled by the same DCM. In this case, both the first terminal and the M first-party target terminals can obtain the target application corresponding to the media function of the target data channel from the network. The first terminal can sequentially send invitation messages, such as reINVITE / 200 OK messages, to the M first-party target terminals, inviting each first-party target terminal to join the multi-party session. Each first-party target terminal confirms the response and joins the multi-party session. At this time, a multi-party session carrying the Bootstrap data channel is established between the first terminal and the M first-party target terminals.

[0095] Scenario 2: The M first-party bootstrap data channels are controlled by different DCMs. In this case, the first terminal can control the M first-party bootstrap data channels to be controlled by the same target DCM, so that both the first terminal and the M first target terminals can obtain the target application corresponding to the target data channel media function from the network.

[0096] In specific implementation, the data channel media function controlling the Bootstrap data channel depends on the channel connection point of the Bootstrap data channel. Optionally, the first terminal can determine whether the M first-party Bootstrap data channels are controlled by the same DCM by obtaining the channel connection point information of the M first-party Bootstrap data channels. After the first terminal establishes a first-party Bootstrap data channel with each of the M first-party target terminals, the data channel server corresponding to each first-party Bootstrap data channel can report the current channel connection point information to the MRS, and the MRS stores the channel connection point information. After initiating a multi-party session, the first terminal can request the conference resources required for the session and obtain the channel connection point corresponding to each first-party Bootstrap data channel from the MRS. The situation where the M first-party Bootstrap data channels are controlled by the same target data channel media function includes the case where the M first-party Bootstrap data channels correspond to the same M first-party channel connection points. The cases where M first-party Bootstrap data channels are controlled by different data channel media functions include: among the M first channel connection points corresponding to the M first-party Bootstrap data channels, at least one first channel connection point is different from the other first channel connection points. If M=2, the cases where Bootstrap data channel 1 and Bootstrap data channel 2 are controlled by the same DCM include: the channel connection point 1 corresponding to Bootstrap data channel 1 is the same as the channel connection point 2 corresponding to Bootstrap data channel 2; the cases where Bootstrap data channel 1 and Bootstrap data channel 2 are controlled by different DCMs include: the channel connection point 1 corresponding to Bootstrap data channel 1 is different from the channel connection point 2 corresponding to Bootstrap data channel 2.

[0097] The specific implementation methods for controlling M first-party Bootstrap data channels to be controlled by the same target data channel media function can include, but are not limited to, the following two:

[0098] Implementation Method 1

[0099] By using DCM synchronization, M first-party Bootstrap data channels are controlled by the same target data channel media function, thereby establishing a multi-party Bootstrap data channel.

[0100] In a specific implementation, the first terminal can control the synchronization of data channels among the M first-party Bootstrap data channels. Optionally, a first instruction message can be sent to the data channel server corresponding to each of the M first-party Bootstrap data channels.

[0101] In this embodiment, the first indication information is used to instruct the data channel servers corresponding to each first-party Bootstrap data channel to synchronize the data channels. Specifically, data channel synchronization can be achieved through data transfer. After data channel synchronization is achieved between the data channel servers corresponding to each first-party Bootstrap data channel, the data transmitted in each first-party Bootstrap data channel can be completely synchronized. They can be regarded as connected to the same channel connection point, that is, controlled by the same data channel media function. The data channel media function corresponding to the current channel connection point is the target data channel media function.

[0102] It should be noted that in other embodiments, the first terminal may request other entities in the network system, such as the MRS, to control the synchronization of data channels between the M first-party Bootstrap data channels. The implementation method can refer to the description of the above embodiments, and the specific implementation can be determined according to the actual situation, and is not specifically limited here.

[0103] When the first terminal completes data channel synchronization between the M first-party Bootstrap data channels, it can send invitation information, such as a reINVITE / 200 OK message, to the M first-party target terminals in sequence to invite them to join the multi-party session. Each first-party target terminal joins the multi-party session after confirming the response.

[0104] To facilitate understanding, let's illustrate with an example: Assume M=2, the first terminal is UE A, and the two first target terminals are UE B and UE C, as follows: Figure 2 As shown:

[0105] If the Bootstrap data channel connection point between UE A and UE B, and the Bootstrap data channel connection point between UE A and UE C are both in DCM A, then UE A sends reINVITE / 200OK messages in sequence to invite UE B and UE C to join the multi-party session. After UE B and UE C confirm the response, they join the multi-party session. At this time, UE A, UE B, and UE C enter a three-party session carrying data channels, and the three-party connection point of the multi-party Bootstrap data channel is in DCM A.

[0106] If the bootstrap data channel connection point between UE A and UE B is in DCM B, and the bootstrap data channel connection point between UE A and UE C is in DCM A, then DCM A and DCM B will synchronize their data channels. After receiving the indication that the data channel synchronization is successful, UE A can send reINVITE / 200OK messages sequentially to invite UE B and UE C to join the multi-party session. After UE B and UE C confirm the response, they will join the multi-party session. At this time, UE A, UE B, and UE C enter a three-party session carrying data channels, and the three-party connection point of the multi-party bootstrap data channel is in DCM A or DCM B.

[0107] If the bootstrap data channel connection point between UE A and UE B is in DCM A, and the bootstrap data channel connection point between UE A and UE C is in DCM C, then DCM A and DCM C will synchronize their data channels. After receiving the indication that the data channel synchronization is successful, UE A can send reINVITE / 200OK messages sequentially to invite UE B and UE C to join the multi-party session. UE B and UE C will then acknowledge and join the multi-party session. At this point, UE A, UE B, and UE C enter a three-party session carrying data channels, and the three-party connection point of the multi-party bootstrap data channel is either DCM A or DCM C.

[0108] If the bootstrap data channel connection point between UE A and UE B is in DCM B, and the bootstrap data channel connection point between UE A and UE C is in DCM C, then DCM B and DCM C will synchronize their data channels. After receiving the indication that the data channel synchronization is successful, UE A can send reINVITE / 200OK messages sequentially to invite UE B and UE C to join the multi-party session. UE B and UE C will then acknowledge and join the multi-party session. At this point, UE A, UE B, and UE C enter a three-way call carrying data channels, with the three-way connection point of the multi-party bootstrap data channel located at either DCM B or DCM C.

[0109] Implementation Method 2

[0110] By using call relocation, M first-party Bootstrap data channels are controlled by the same target data channel media function, thereby establishing a multi-party Bootstrap data channel.

[0111] In practice, the first terminal can control M first-party Bootstrap data channels to achieve call relocation. Optionally, a second indication message can be sent to M first-party target terminals.

[0112] In this embodiment, the second indication information is used to instruct the M first target terminals to perform call relocation, that is, to establish a second two-way Bootstrap data channel between any two of the M first target terminals, and the second channel connection point corresponding to the second two-way Bootstrap data channel is the same as at least one of the M first channel connection points corresponding to the M first two-way Bootstrap data channels. In other words, any one of the M first target terminals can act as a session initiator to initiate a two-way session to other first target terminals and establish a corresponding second two-way Bootstrap data channel. By controlling the channel connection point of the second two-way Bootstrap data channel, the first terminal and the M first target terminals can all be controlled by the same data channel media function.

[0113] It should be noted that in other embodiments, the first terminal may request other entities in the network system, such as the MRS, to control the M first two-way Bootstrap data channels to achieve call relocation. The implementation method can refer to the description of the above embodiments, and the specific implementation can be determined according to the actual situation, and is not specifically limited here.

[0114] When the first terminal achieves call relocation between M first-party Bootstrap data channels, it can sequentially send invitation information, such as a reINVITE / 200 OK message, to the M first-party target terminals to invite them to join the multi-party session. Each first-party target terminal joins the multi-party session after confirming the response.

[0115] To facilitate understanding, here's an example: Assume the first terminal is UE A, the second terminal is UE B, and the third terminal is UE C, such as... Figure 3 As shown:

[0116] If the Bootstrap data channel connection point between UE A and UE B, and between UE A and UE C, are both located in DCM A, then UE A will sequentially send reINVITE / 200OK messages to invite UE B and UE C to join the multi-party session. UE B and UE C will then acknowledge and join the multi-party session. At this point, UE A, UE B, and UE C will enter a three-party session carrying data channels, and the three-party connection point of the multi-party Bootstrap data channel will be located in DCM A.

[0117] If the Bootstrap data channel connection point between UE A and UE B is at DCM B, and the Bootstrap data channel connection point between UE A and UE C is at DCM A, then a single DC call will be made between UE B and UE C. In this case, the channel connection point of the Bootstrap data channel established between UE B and UE C is DCM B, making UE A, UE B, and UE C connected to the same channel connection point.

[0118] If the Bootstrap data channel connection point between UE A and UE B is at DCM A, and the Bootstrap data channel connection point between UE A and UE C is at DCM C, then a single DC call will be made between UE B and UE C. In this case, the channel connection point of the Bootstrap data channel established between UE B and UE C is DCM C, making UE A, UE B, and UE C connected to the same channel connection point.

[0119] If the Bootstrap data channel connection point between UE A and UE B is at DCM B, and the Bootstrap data channel connection point between UE A and UE C is at DCM C, then a single DC call will be made between UE B and UE C. In this case, the channel connection point of the Bootstrap data channel established between UE B and UE C will be either DCM B or DCM C, so that UE A, UE B, and UE C are connected to the same channel connection point.

[0120] Specifically, prior to step 103, the multi-party communication method also includes:

[0121] Based on multi-party sessions and multi-party Bootstrap data channels, the target application is obtained from the target data channel media function, and user information of N second target terminals is sent to the target data channel server.

[0122] Send a request message to the target data channel server. The request message carries user information of N second target terminals. The request message is used to request the target data channel server to notify each second target terminal to obtain the target application from the target data channel media function based on the multi-party Bootstrap data channel.

[0123] Step 103 includes:

[0124] When all N second target terminals obtain the target application from the target data channel media function, a multi-party application data channel is established between the target application and the N second target terminals, and communication is carried out with the N second target terminals based on the multi-party application data channel.

[0125] In this embodiment, step 101 establishes a multi-party Bootstrap data channel controlled by the target data channel media function between the first terminal and the M first target terminals. Both the first terminal and the M first target terminals can obtain the target application corresponding to the target data channel media function from the network based on the aforementioned multi-party Bootstrap data channel.

[0126] In practice, the first terminal can obtain the target application from the target data channel server corresponding to the target data channel media function. In addition, the first terminal can determine the second target terminal to communicate with based on business needs and request the target data channel server to notify the second target terminal to obtain the target application from the target data channel server based on the aforementioned multi-party Bootstrap data channel.

[0127] For ease of understanding, assume N=2, the first terminal is UE A, the two second target terminals are UE B and UE C, and the target data channel media function is DCM B. For example... Figure 4 As shown, UE A can independently obtain the target application from the data channel server corresponding to DCM B. Furthermore, UE A can send a request message carrying user information of UE B and UE C to the data channel server corresponding to DCM B, based on business needs. Upon receiving the request message, the data channel server corresponding to DCM B can notify UE B and UE C to obtain the target application from the data channel server corresponding to DCM B based on the aforementioned multi-party Bootstrap data channel. After UE A, UE B, and UE C have all obtained the target application, an Application data channel can be established between any two of UE A, UE B, and UE C, achieving full connection of the Application data channel. Specifically, taking the establishment of an Application data channel between UE A and UE B as an example, UE A can send an invitation message to UE B to establish an Application data channel, such as a reINVITE / 200 OK message. Upon receiving the invitation message, UE B can send a response message as an answer. After all the point-to-point fully connected multi-party Application data channels are established, the call voice is mixed in MRS and can be sent to each participant in the multi-party communication.

[0128] Figure 5 This is a complete implementation of an embodiment of the present invention. It should be noted that in this embodiment, the participants in multi-party communication are not limited to three parties, but can include more than three parties. In multi-party communication scenarios with more than three parties, the corresponding steps can be repeated as described above, and will not be elaborated further here.
