Unified communications-based video conference call method, device and system

摘要

A unified communications (UC)-based video conference call method and system, and a device, where receiving, by a first UC client, a request for querying call information of a second video conference terminal (VCT), where the request includes an identifier of a called contact; sending the query request to a UC server, and receiving the call information of the second VCT; and sending, by the first UC client, the call information of the second VCT to a first VCT, hence the first VCT initiates a video conference call to the second VCT according to the call information of the second VCT. By integrating a personal computer (PC)-based UC system with a hardware video conference system that is based on a digital signal processor (DSP) and embedded software, a high-quality video conference can be initiated and held using a UC client, thereby boosting user experience and enhancing product competitiveness.

主权项

1. A unified communications (UC)-based video conference subsystem connected to a network, comprising:
a video conference terminal (VCT); a PC (personal computer) host; a UC client; a user input device, wherein the UC client is installed on the PC host, wherein the PC host is connected to the network and the user input device, wherein the VCT is connected to the PC host, wherein the UC client further comprises:
a VCT application module; anda UC-VCT communications module, wherein the VCT comprises:
a video processing module;a call control module;a VCT-UC communications module,wherein the call control module is connected to the video processing module,wherein the VCT-UC communications module is connected to the call control module,wherein the VCT-UC communications module is configured to:
receive the call information of the called VCT sent by the UC-VCT communications module;send the call information of the called VCT to the call control module;receive the incoming video conference call message that comprises the incoming call number;send the incoming video conference call message to the VCT application module using the UC-VCT communications module;receive one of the call answer, reject request; andsend one of the call answer, reject request to the call control module wherein the call control module is configured to:receive the call information of the called VCT;initiate a video conference call to the called VCT according to the call information of the called VCT;receive one of the call answer, reject request; andperform one of the answering, rejecting operation on the incoming call, 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, wherein the UC server connected to the network;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 one of the call answer, reject request input by a user; andsend the request to the UC-VCT communications module,wherein the UC-VCT communications module is configured to:
establish a communication channel between the UC client and the VCT;receive the call information of the called VCT;send the call information of the called VCT to the VCT-UC communications module of the VCT;receive the call answer or reject request; andsend the call answer or reject request to the VCT-UC communications module, wherein the user input device is configured to:
receive the request for querying the call information of the called VCT; andsend the query request to the VCT application module.
