[0016] The traditional point to point video communication process: video communication terminal call the other number which is sent to the GK (Gateke printed er, gatekeeper), GK for the terminal number dialed for address resolution, to find the address of the called terminal , and then create a connection between two terminals, thereby establishing video communications.

[0017] This method is by number mapping and message feedback manner directed to various value-added services. Namely: video terminal call some special number that passed H. 323 of RAS (Registration, Admission and Status, registration, admission, and status) protocol, which is the endpoint and GK RAS protocol agreement between the endpoints defined in and GK registration between the access, bandwidth changes, status, and from the process. According to the present invention, the number to the GK, GK resolved by not establishing the terminal to another terminal or MCU (Multipoint Control Unit, multi-point control unit) a call, but by GK directed to other services (such as video on demand , WEB browsing, etc.).

[0018] Referring to the drawings 1, Figure l shows a H. 323 according to the present invention uses a standard protocol of the service control RAS triggered by clients field value added services for video booting, the method comprising:

[0019] (1) user terminal via a video call some special number, which, like other video calling through ARQ (Admission Request, Access Request) signaling message is sent to the GK, wherein the ARQ signaling message belongs RAS protocol involved in a signaling message.

[0020] (2) GK dialed number for the user to parse, determine the business and its operations to boot entry point parameter, and value-added services, including value-added service entry point parameters to guide instruction information encapsulated in the ARJ (Admission Reject, access reject) the signaling message returned. Similarly, signaling messages are also part of the ARJ RAS protocol signaling messages involved in a
