In another implementation scenario, if the user of the attached terminal does not open the one-number multi-terminal service or the main card bound with the attached card is cancelled, the voice call of the attached terminal does not need to be connected to the main terminal.

S605: and the voice connection service management unit determines the positions of the main terminal and the auxiliary terminal according to the card attaching service opening information.

In an implementation scenario, the positions of the main terminal and the auxiliary terminal can be determined through one or more positioning modes such as a mobile network, a global positioning system, WIFI and the like. For example, when the mobile network is used to obtain the positions of the main terminal and the accessory terminal, the main terminal log-in record and the accessory terminal log-in record can be obtained from the signaling system. Because the log-on record contains the information of the base station and the cell accessed by the terminal, the information of the base station and the cell accessed by the main terminal can be obtained according to the log-on record of the main terminal, and then the position of the main terminal can be determined. And acquiring the information of the base station and the cell accessed by the auxiliary terminal according to the network log-in record of the auxiliary terminal, and further determining the position of the auxiliary terminal.

In an implementation scenario, if the main terminal and the accessory terminal are not located at the same position, the voice call of the accessory terminal does not need to be connected to the main terminal.

S606: if the main terminal and the auxiliary terminal are at the same position, the voice connection service management unit sends a voice connection service request to the application server.

The voice connection service request is used for the application server to connect the voice of the attached terminal to the main terminal, and may include main terminal information and main card information, and terminal information and card information of an opposite terminal user of the current voice call.

S607: the application server connects the voice call of the auxiliary terminal to the main terminal.

In an implementation scenario, the process of the application server connecting the voice call of the accessory terminal to the main terminal may refer to fig. 7, which is as follows:

step 1, the application server sends a session initiation protocol request INVITE message to a call session control function of a network domain where the main terminal is located, and forwards the INVITE message to the main terminal.

The session initiation protocol request INVITE message carries media information of the terminal of the opposite terminal user of the current voice call. The media information may be described using a session description protocol, and is used for the main terminal to perform media negotiation with the terminal of the opposite-end user of the current voice call.

And step 2, establishing a wireless bearer between the main terminal and the base station, and establishing a voice special bearer with the service gateway/packet data network gateway.

It should be noted that, during the call between the terminal of the opposite end user of the current voice call and the additional terminal, the voice call function of the additional terminal is failed, at this time, the voice dedicated bearer between the serving gateway/packet data network gateway of the network domain where the additional terminal is located and the additional terminal is released or interrupted, and the voice dedicated bearer between the terminal of the opposite end user of the current voice call and the serving gateway/packet data network gateway of the network domain where the terminal is located is still maintained in a normal state.

And 3, the main terminal sends the session initial protocol session response 200OK message to the application server through the call session control function of the network domain where the main terminal is located.

And 4, the application server sends the session initial protocol session UPDATE UPDATE message to the terminal of the current voice call opposite-end user through the call session control function of the network domain where the terminal of the current voice call opposite-end user is located.

Session initiation protocol session UPDATE message carries media information of the master terminal. And sending the session initial protocol session UPDATE UPDATE message to the terminal of the current voice call opposite terminal user, and indicating the terminal of the current voice call opposite terminal user to perform session UPDATE and responding to the initial protocol session UPDATE UPDATE message.

And step 5, the terminal of the current voice call opposite-end user sends the session initial protocol session update response 200OK message to the application server through the call session control function of the network domain where the terminal is located.

After receiving the session initiation protocol session update response 200OK message, the application server rings to the main terminal, and the main terminal makes the main terminal establish a voice call with the terminal of the opposite terminal user of the current voice call through an off-hook response.

In an implementation scenario, the voice between the main terminal and the terminal of the peer user of the current voice call may be transmitted through an RTP (Real-time Transport Protocol).

The embodiment of the application provides a terminal voice connection method, and a service gateway/packet data network gateway judges the voice call state of an attached terminal by sensing the special voice bearing condition. And when the current voice call state of the auxiliary terminal is judged to be abnormal, the service gateway/packet data network gateway sends the current voice call fault information of the auxiliary terminal to the voice connection service management unit. And the voice connection service management unit sends a card attaching service opening information query request to the information technology support system according to the terminal attaching information and the card attaching information in the current voice call fault information of the terminal attaching. The information technology support system inquires the card attaching service opening information and returns the card attaching service opening information to the voice connection service management unit. And the voice connection service management unit determines the positions of the main terminal and the auxiliary terminal according to the card attaching service opening information and judges whether the main terminal and the auxiliary terminal are positioned at the same position. When the two are in the same position, the voice connection service management unit sends a voice connection service request to the application server. The application server connects the voice call of the auxiliary terminal to the main terminal. The main terminal user can realize the voice call between the main terminal and the opposite terminal user of the current voice call through off-hook response, thereby improving the flexibility of the voice call.

S810: the call session control function sends a message authentication request to the policy and charging rules function.

The message Authentication Authorization Request (AAR) includes an application identifier, media description information, location information, and the like.

S811: the policy and charging rules function sends a random access request to the serving gateway/packet data network gateway.

The policy and charging rules function unit sends a Random Access Request (RAR) to the serving gateway/packet data network gateway, so as to instruct the serving gateway/packet data network gateway to establish a dedicated voice bearer.

S812: a voice dedicated bearer is established between the serving gateway/packet data network gateway and the calling terminal.

S813: the serving gateway/packet data network gateway sends a random access response message to the policy and charging rules function.

S814: the policy and charging rules function sends a message authentication response message to the call session control function.

S817: and the session control function receives the 200OK message of the PRACK message sent by the network domain where the called terminal is located and sends the 200OK message of the PRACK message to the calling terminal.

The 200OK message is a called off-hook answer message.

S818: the calling terminal performs a media negotiation procedure.

In an implementation scenario, a calling terminal sends a media stream UPDATE message (UPDATE message) carrying an SDP (Session Description Protocol) to a call Session control function, and the call Session control function sends the media stream UPDATE message carrying the SDP to a network domain where a called terminal is located. The called terminal responds to the media stream updating message carrying the SDP, sends a 200OK message corresponding to the media stream updating message to the calling session control function, and forwards the 200OK message to the calling terminal by the calling session control function.

S819: and the call session control function receives the 180Ring message sent by the network domain where the called terminal is located and forwards the 180Ring message to the calling terminal.

180 message is a called ringing message.

S820: the calling terminal responds to the 180Ring message.

S821: and the call session control function receives a 200OK message which is sent by the network domain where the called terminal is located and corresponds to the call INVITE message, and forwards the 200OK message which corresponds to the call INVITE message to the calling terminal.
