Description

Call establishment method and system

technical field

The present invention relates to the technical field of communication, in particular to a call establishment method and system.

Background technique

During the video call, the video chat application is supported to be installed on super phones and super TVs. Mobile phones and super TVs are sold worldwide, so video chat apps also need to support worldwide communication. In the process of globalization, many additional requirements have been put forward for the video chat application itself, such as cross-computer room signaling interaction, cross-computer room lock, and cross-computer room data synchronization.

In a globalized video call, both parties to the call may be connected in different countries, and a user may be bound to multiple devices at the same time. For example, a user in Beijing calls the mobile phone number of a user in New York, while The New York user has another TV in Tokyo, and both the called devices are turned on, so after the Beijing user dials the number, the two devices in New York and Tokyo must be able to ring. In order to be able to make a call at any time, it is necessary to synchronize the information of the user equipment to the global computer room through a cross-regional data synchronization method when the user equipment is online (for example, the user equipment is turned on and off, connected to the network/disconnected, etc.), so as to facilitate the establishment of During a call, it is possible to determine the current area of the communication parties according to the information of the synchronized calling and called user equipment, so as to determine the computer room that the communication parties are currently connected to, so as to transmit the call signaling to the computer room that the communication parties are connected to.

However, the inventor has found in practice that wireless Internet communication mobile phones are likely to go online and offline or change locations at any time. Therefore, the synchronization of online status and location information will be more frequent. There is a phone call before the device information. At this time, the phone call of the mobile phone cannot be connected, so there is a problem of untimely synchronization. For the real-time data and high accuracy requirements, the video call is even more unsatisfied.

S31. Configure the called processing computer room to call the remote call interface of the called processing computer room when the called party is in an idle state;

S32. Configure the called processing equipment room to send the calling signaling to all calling devices corresponding to the called through the remote calling interface.

In the above embodiment, the called party being in an idle state means that all communication devices corresponding to the called party are not in communication.

In this embodiment, the call signaling is sent to all call devices corresponding to the called device through the remote call interface of the called processing machine room, thereby realizing the interaction of call signaling across the machine rooms. Specifically, in this embodiment, a logical judgment is first carried out to determine whether all communication devices corresponding to the current called are in an idle state, and if so, ignore this call, otherwise, the call will be made through the remote call interface of the called processing room. The signaling is sent to all calling devices corresponding to the called party, realizing the interaction of calling signaling across the computer room.
