METHOD FOR REALIZING SERVICE ACTIVATION OPERATION AND USER TERMINAL REALIZING THE METHOD

摘要

A method for realizing service activation operation. The method comprises: attaching the service activation information inputted by a user in service activation information field for taking each service activation operation required information in service activation message, and transmitting the information to network side, the network side identifies the initial content of service activation according to the received service activation information so that realizing initiating for service activation operation. The present invention also discloses a terminal device, the terminal device comprises a set unit and a control unit and a transmission unit. With the present invention, the terminal can complete the corresponding service activation operation as long as SIP terminals support basic function or SIP terminals through a expanding support of fixed and adapted to all service activation operation mode, in packet central network which call control signaling is SIP, without needing the SIP terminal performs different expanding supports for activation operation of different services, and reducing the manufacture cost and sale price of a SIP terminal.
