Detailed Description
The following detailed description of embodiments of the invention refers to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present invention, are given by way of illustration and explanation only, not limitation.
In the method for establishing a three-way call provided in this embodiment, a three-way call is established between different communication networks and different application programs, for example, a first session is established between a first terminal and a second terminal through a Fifth generation (5G) mobile communication network by a phone program of the first terminal and the second terminal, the first terminal wants to join a third terminal into the first session through another application program to establish the three-way call, and the third terminal is connected to the internet.
For the sake of distinction from the telephone program, the application program referred to in the present embodiment is an application program capable of audio/video call other than the telephone program.
It should be noted that, because the third terminal and the first terminal and the second terminal use different networks, the third terminal cannot be directly connected to a Session Management Function (SMF), and a communication server corresponding to the third terminal needs to establish signaling connection and service connection with the first terminal by means of a Non-3GPP Inter Working Function (N3 IWF).
As shown in fig. 1, the method for establishing a three-way call provided in this embodiment includes the following steps:
step S101, suspending the service connection of the first session in response to the suspend request forwarded by the first application in the first terminal, and sending a suspend completion message to the first application.
Wherein the first session is a call established by a first application program of the first terminal and a second application program of the second terminal through the mobile communication network. The suspend request means to suspend the service connection between the first terminal and the second terminal, but the signaling connection is still reserved, in other words, the first terminal and the second terminal temporarily suspend the call service, but the first terminal and the second terminal still maintain the signaling connection with the session management function entity, i.e. still can send and receive the instruction signal. The hang-up request comprises a three-party call mark, namely after the session management functional entity receives the hang-up request, the first session is hung up based on the three-party call.
In one embodiment, after a first session is established by a phone program in a first terminal with a phone program in a second terminal, the first terminal wishes to join a third terminal to the first session through an application. Thus, the phone program in the first terminal invokes the application program in the first terminal to attempt to establish a three-way call. Specifically, a user touches a call interface of the first terminal, the first terminal automatically jumps to an operation interface, and the operation interface comprises an operation button group which comprises a button for initiating a three-party call. Clicking the button for initiating the three-party call to generate an option of 'opposite-end user type', wherein the option comprises 'other application options', clicking other application options, generating an application program list supporting audio and video calls, and selecting an application program from the application program list, such as a WeChat program. When the open application selects the contact that wants to talk, the application sends a suspend request to suspend the first session to the phone program in the first terminal.
In one embodiment, when a first application within the first terminal invokes a second application, the second application sends a suspend first session request to the first application. For example, when a phone program in the first terminal calls an application program, the application program issues a suspend request to the phone program. The suspension request is initiated by the invoked second application to facilitate synchronous operation of the first application and the second application.
It should be noted that, in the call request initiated by the first application program of the first terminal to the second application program, a parameter of the call type, that is, a flag of the three-way call, is included to indicate that the suspend request is a suspend request based on the three-way call, so that the second application program can know that the purpose of the call of the first application program is the three-way call.
Step S102, changing the parameter of the first session into a three-party call in response to the three-party call request of the communication server corresponding to the third terminal.
The first session is an audio-video call established by a telephone program in the first terminal and a telephone program in the second terminal, namely, the parameter of the first session is a two-party call, and when the session management functional entity receives a three-party call request of the communication server, the session parameter needs to be changed into a three-party call.
In one embodiment, the communication server sends a three-way call request to the session management function entity upon receiving a call request from a second application in the first terminal, where the call request includes a three-way call flag, a passcode for accessing the three-way call, a number of the first terminal (chip id), and a number of the second terminal (chip id).
Specifically, after suspending the first session, the first application program in the first terminal sends a suspended message to the second application program, where the message includes a passcode for accessing the three-party call. And after receiving the suspended message, the second application program in the first terminal sends a call request to the communication server. Because the suspended message fed back to the second application program by the first application program contains the password code for accessing the three-party call, after receiving the suspended message, the second application program sends a call request to the communication server.
After receiving a call request sent by a second application program in the first terminal, the communication server establishes signaling connection (pre-establishment) with the third terminal according to a three-party call mark in the call request, namely the communication server can send instruction information to the third terminal, but service connection is not established, and the third terminal cannot carry out call.
After the communication server establishes signaling connection with the third terminal, the communication server sends a three-party call request to the session management function entity, wherein the three-party call request comprises the number of the first terminal, the number of the second terminal and a password code for accessing the three-party call, and after the session management function entity receives the three-party call request, the session management function entity can send an instruction to the first terminal and the second terminal according to the numbers of the first terminal and the second terminal in the three-party call request.
It should be noted that, before the communication server sends a request or an instruction to the session management function entity for the first time, the communication server needs to access the 5G core network and pass authentication. Specifically, the communication server sends a request for accessing a 5G core network to the non-3GPP interworking functional entity, the non-3GPP interworking functional entity sends the access request to a Unified Data Management entity (UDM), and the UDM authenticates the communication server, that is, determines whether the communication server opens a three-party call service, and if the authentication fails, the three-party call cannot be established. And if the authentication is passed, interacting with the communication server to complete the access operation, and directing the session connection relation of the communication server to the session management functional entity, namely, providing the session service of the communication server in the 5G core network by the session management functional entity.
It should be noted that the session management functional entity pointed by the session connection relationship of the communication server may be the same session management functional entity as the session management functional entity pointed by the first terminal, or may be two different session management functional entities.
When the session management functional entity pointed by the communication server and the session management functional entity pointed by the first terminal are the same session management functional entity, the communication server directly sends a three-party call request to the session management functional entity. When the session management functional entity pointed to by the communication server and the session management functional entity pointed to by the first terminal are two different session management functional entities, assuming that the first terminal points to the first session management functional entity and the communication server points to the second session management functional entity, the communication server firstly sends a three-party call request to the second session management functional entity, and then the second session management functional entity forwards the three-party call request to the first session management functional entity.
Step S103, sending a message for allowing the third terminal to join the three-party call to the communication server.
And after the session management functional entity changes the parameters of the first session into the parameters of the three-party call, sending a session state modification result to the communication server, namely allowing the third terminal to join the three-party call.
And step S104, resuming the service connection of the suspended first session.
After the session management functional entity changes the parameters of the first session into the parameters of the three-party call, an instruction for recovering the suspended first session is sent to the first application program in the first terminal and the second terminal, so that the first terminal and the second terminal recover service connection.
It should be noted that step S103 and step S104 may be executed sequentially or simultaneously.
And step S105, when the third terminal agrees to join the three-party call, establishing the three-party call among the second application program in the first terminal, the telephone program in the second terminal and the application program in the third terminal.
In one embodiment, after the communication server receives the permission of the session management function entity to join the three-party session, the communication server sends a session modification command and a ringing signaling to the third terminal. After the third terminal receives the session modifying command, the application program in the third terminal executes off-hook operation and sends an execution feedback message of the off-hook operation to the communication server, and three-party communication is established among the second application program in the first terminal, the telephone program in the second terminal and the application program in the third terminal.
After receiving the feedback message of the off-hook operation of the third terminal, the communication server sends a confirmation message that the application program in the third terminal has joined the three-party call to the session management functional entity, and the session management functional entity forwards the confirmation message that the third terminal has joined the first application program of the first terminal. And the communication server sends a switching instruction to the second application program of the first terminal so that the first terminal switches the second application program to the background.
The steps of the above methods are divided for clarity, and the implementation may be combined into one step or split some steps, and the steps are divided into multiple steps, so long as the same logical relationship is included, which are all within the protection scope of the present patent; it is within the scope of the patent to add insignificant modifications to the algorithms or processes or to introduce insignificant design changes to the core design without changing the algorithms or processes.

In addition, in order to highlight the innovative part of the present invention, elements that are not so closely related to solving the technical problems proposed by the present invention are not introduced in the present embodiment, but this does not indicate that other elements are not present in the present embodiment.
According to the device for establishing the three-party call, the suspension module responds to the suspension request forwarded by the first application program in the first terminal to suspend the service connection of the first session, the first sending module sends the suspension completion message to the first application program, the change module responds to the three-party call request of the communication server corresponding to the third terminal to change the parameter of the first session into the three-party call, and the second sending module sends the message allowing the third terminal to join the three-party call to the communication server; the recovery module recovers the service connection of the suspended first session; when the third terminal agrees to join the three-party call, the third-party call among the second application program in the first terminal, the telephone program in the second terminal and the application program in the third terminal is established, so that the three-party call among different networks and different application programs is established, and the user experience is improved.
The method and apparatus for establishing a three-way call provided in this embodiment are described in detail in a more specific implementation manner. In the embodiment, a first terminal UE1, a second terminal UE2, a third terminal UE3, a first session management function module SMF1, a second session management function module SMF2, a non-3GPP interworking function entity N3IWF, a communication server 37, and a unified data management entity UDM are used, where the first terminal includes a first terminal phone program UE1A and a first terminal application program UE 1B.
As shown in fig. 3, the three-party call is established as follows:
step S301, the phone program of the first terminal initiates a call request to the application program of the first terminal.
Before the calling request is initiated by the telephone program of the first terminal, the telephone program of the second terminal of the telephone program of the first terminal establishes a two-party (two-party) call. The manner of calling the application program to the first terminal by the phone program of the first terminal is the same as step 101 in this embodiment, and is not described herein again.
Step S302, the application program of the first terminal initiates a suspension request to the telephone program of the first terminal.
When the application program of the first terminal is called by the telephone program of the first terminal, the application program of the first terminal initiates a suspension request for suspending the first session to the telephone program of the first terminal, and a three-way call mark is included in the suspension request, namely, the reason why the first session is suspended is that a three-way call is to be established.
Step S303, the phone program of the first terminal forwards the suspend request to the first session management function entity.
Step S304, the first session management function entity interacts with the phone program of the first terminal and the phone program of the second terminal to suspend the first session.
Step S305, the first session management functional entity and the telephone program of the first terminal return the password code for accessing the three-party call.
Step S306, the phone program of the first terminal returns a suspended message to the application program of the first terminal.
The suspended message returned by the telephone program of the first terminal contains (carries) the password code for accessing the three-party call.
Step S307, the application program of the first terminal initiates a call request to the communication server.
The call request includes (carries) a three-party call flag, a password code for accessing the three-party call, a number (telephone number) of the first terminal and a number (telephone number) of the second terminal.
And step S308, the communication server interacts with an application program in the third terminal to complete the pre-establishment of the audio and video session.
The pre-establishment means that the communication server establishes signaling connection with an application program in the third terminal, but does not establish service connection, that is, signaling is established, but transmission of call content is not established.
Step S309, the communication server sends an access request to the non-3GPP interworking function entity.
Since the communication server and the mobile communication network belong to different networks, the communication server needs to initiate an access request to the mobile communication network. When the mobile communication network is a 5G mobile communication network, the communication server sends an access request to the non-3GPP interworking function entity.
Step S310, the non-3GPP interworking function entity initiates an authentication request to the unified data management entity.
When the communication server accesses the 5G core network for the first time, the 5G core network needs to authenticate the communication server, i.e. to authenticate the authority of the communication server. If the authentication is not passed, the three-party call connection cannot be established. And when the authentication is passed, continuing the subsequent steps.
Step S311, the non-3GPP interworking function entity completes the connection with the communication server in an interactive manner, and directs the session connection relationship to the second session management function entity.
When the session connection relation of the communication server is pointed to the second session management function entity, the second session management function entity provides the session service of the communication server in the 5G core network. The specific access mode of the communication server is the same as the standard access mode specified by the 3GPP specification, and is not described herein again.
In step S312, the communication server sends a three-way call request to the first session management function entity.
The communication server sends the three-party call request to the second session management functional entity, and then the second session management functional entity forwards the three-party call request to the first session management functional entity. The three-party call request comprises a password code for accessing the three-party call, the number of the first terminal and the number of the third terminal.
In step S313, the first session management functional entity changes the state of the suspended first session into a three-party call according to the number of the first terminal, the number of the third terminal, and the password code for accessing the three-party call.
In step S314, the first session management function entity sends the first session state modification result via the second session management function entity.
Step S315, the first session management functional entity sends a first session resuming instruction to the phone program in the first terminal and the phone program in the second terminal, and causes the phone program in the first terminal and the phone program in the second terminal to resume the first session.
In step S316, the communication server modifies the session command and the ring signaling to the application of the third terminal.
The session modifying command is to modify the application program of the first terminal to the application program of the opposite terminal of the third terminal into a telephone program, namely, the telephone program of the first terminal is in butt joint with the application program of the third terminal.
In step S317, the application program of the third terminal performs an off-hook operation after receiving the ringing signaling.
