Abstract

The embodiment of the invention relates to a call establishment method and system, a video communication server and a strategy control functional entity. The method comprises the following steps of: receiving a call request sent by an application program of the calling terminal, sending a first query request to the policy control function entity, receiving switching information which is fed back by the strategy control function entity based on the identifier and is used for switching the video call mode into the voice call mode, and sending a second query request for querying the called numbercorresponding to the identifier to the unified data storage library according to the switching information, receiving the called number fed back by the unified data storage library based on the second query request, and establishing a voice call connection between the calling terminal and the called terminal according to the called number. Through the technical scheme provided by the embodiment of the invention, the technical defect that the video call mode cannot be switched to the voice call mode in the prior art is avoided, and the technical effects of flexibly determining the call mode, saving the call cost of the user and improving the consumption experience of the user are realized.

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...
