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

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

In one implementation scenario, the locations of the main terminal and the accessory terminal may be determined by one or more positioning modes such as a mobile network, a global positioning system, and WIFI. For example, when the mobile network is used to obtain the locations of the main terminal and the auxiliary terminal, the signaling system may be used to obtain the network log of the main terminal and the network log of the auxiliary terminal.

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

In one implementation scenario, the process of the application server connecting the voice call of the accessory terminal to the main terminal may be shown in fig. 7, which is specifically as follows:

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

The session initiation protocol requests the media information of the terminal of the opposite terminal user of the current voice call to be carried in the INVITE message. The media information may be described using a session description protocol for media negotiation by the master terminal with the terminal of the opposite user of the current voice call.

And 2, establishing a radio 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 and the terminal of the opposite terminal user of the current voice call, the voice call function of the opposite terminal fails, at this time, the voice dedicated bearer between the serving gateway/packet data network gateway of the network domain where the opposite terminal is located and the opposite terminal will be released or interrupted, and the voice dedicated bearer between the terminal of the opposite terminal user of the current voice call and the serving gateway/packet data network gateway of the network domain where the terminal is located will still maintain a normal state.

And step 3, the main terminal sends the session response 200OK message of the session initiation protocol 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 initiation protocol session UPDATE message to the terminal of the current voice call opposite terminal user through the call session control function of the network domain where the terminal of the current voice call opposite terminal user is located.

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

And step 5, the terminal of the current voice call opposite terminal user sends a session initiation 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 200OK message of the session initiation protocol session update response, the application server rings the main terminal, and the main terminal enables the main terminal to establish the voice call with the terminal of the opposite terminal user of the current voice call through off-hook response.

In one implementation scenario, speech between a host terminal and a terminal of a peer user of a current voice call may be transmitted via RTP (Real-time Transport Protocol ).

The embodiment of the application provides a terminal voice connection method, wherein a service gateway/packet data network gateway judges the voice call state of an accessory terminal by sensing the special bearing condition of voice. When judging that the current voice call state of the auxiliary terminal is 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. The voice connection service management unit sends an information technology support system an information card service opening information inquiry request according to the attached terminal information and the attached card information in the current voice call fault information of the attached terminal. The information technology supporting system inquires the opening information of the card attaching service and returns the opening information of the card attaching service to the voice connection service management unit. The voice connection service management unit determines the positions of the main terminal and the auxiliary terminal according to the auxiliary card 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 the off-hook response, so that the flexibility of the voice call is improved.

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

S818: the calling terminal performs a media negotiation process.

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