Unified Communications-Based Video Conference Call Method, Device and System

A unified communications (UC)-based video conference call method, comprising:

• receiving, by a video conference terminal (VCT) application module of a first UC client, a request for querying call information of a second VCT serving as a called party, wherein the second VCT is a VCT used by a called contact, and wherein the request comprises an identifier of the called contact;
• sending, by the VCT application module of the first UC client, the query request to a UC server;
• receiving the call information of the second VCT, wherein the call information is queried and obtained by the UC server according to the identifier of the called contact in the query request;
• and
• sending, by the VCT application module of the first UC client, the call information of the second VCT to a call control module of a first VCT using a UC-VCT communications module of the first UC client and a VCT-UC communications module of the first VCT, to enable the call control module of the first VCT to initiate a video conference call to the second VCT according to the call information of the second VCT.

A video conference terminal (VCT) comprising:

• a video processing module;
• a call control module;
• and
• a VCT-unified communications (VCT-UC) communications module;
• wherein the VCT-UC communications module connected to the call control module,
• wherein the VCT-UC communications module is configured to:
• receive call information of a called VCT sent by a unified communications-video conference terminal (UC-VCT) communications module;
• send the call information of the called VCT to the call control module;
• receive an incoming video conference call message that comprises an incoming call number;
• send the incoming video conference call message to a VCT application module using the UC-VCT communications module;
• receive a call answer or reject request;
• and
• send the call answer or reject request to the call control module,
• wherein the call control module is configured to:
• receive the call information of the called VCT;
• and
• initiate a video conference call to the called VCT according to the call information of the called VCT;
• receive the call answer or reject request;
• and
• perform an operation of answering or rejecting the incoming call.

A unified communications (UC) client, comprising:

• a video conference terminal (VCT) application module;
• a UC-VCT communications module,
• wherein the VCT application module is configured to:
• receive a request for querying call information of a called VCT;
• send the query request to a UC server;
• receive the call information of the called VCT that is returned by the UC server;
• send the call information of the called VCT to the UC-VCT communications module;
• receive an incoming video conference call message that comprises an incoming call number;
• send a calling party information query request that comprises the incoming video conference call message to the UC server;
• receive calling party information of the video conference call, wherein the calling party information is queried and obtained by the UC server according to the incoming call number;
• output the calling party information of the video conference call in a visual manner;
• receive a call answer or reject operation request input by a user;
• and
• send the request to the UC-VCT communications module, and
• wherein the UC-VCT communications module is configured to:
• establish a communication channel between the UC client and the called VCT;
• receive the call information of the called VCT;
• send the call information of the called VCT to a VCT-UC communications module of the VCT;
• receive the call answer or reject request;
• and
• send the call answer or reject request to the VCT-UC communications module.
