Abstract

The embodiment of the present invention relates to a call establishment method and system, a video communication server, and a policy control functional entity. The method includes: receiving a call request sent by an application program of a calling terminal, sending a first query request to a policy control functional entity, and receiving a response from the policy control functional entity based on an identifier for switching a mode of video calling to a mode of voice calling Switching information, sending a second query request for querying the called number corresponding to the identification to the unified data repository according to the switching information, receiving the called number fed back by the unified data repository based on the second query request, and establishing the calling number according to the called number The connection of the voice call between the terminal and the called terminal. Through the technical solutions provided by the embodiments of the present disclosure, the technical disadvantages in the prior art that the video call mode cannot be switched to the voice call mode are avoided, and the technology of flexibly determining the call mode, saving the user's call cost, and improving the user's consumption experience is realized. Effect.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of communication, and in particular to a call establishment method and system, a video communication server, and a policy control functional entity. Background technique [0002] With the popularization of terminals and telecommunication services, terminals (such as mobile phones) are generally used to make calls between users, thereby realizing communication and exchanges. [0003] As is well known, there are two ways to realize the call connection between the calling terminal and the called terminal, one is a voice call (ie, a mobile communication network call), and the other is a video call (ie, an IP network call). However, the two calling methods cannot exist at the same time. [0004] In the prior art, when the calling user calls the user through the calling terminal, he can log in to the official website of the operator, or go to the service hall of the operator to apply for...
