1. A plug-in service method performed at a user equipment, the method comprising:
- receiving contents data, wherein the contents data comprises media data;
recording specification information into a predetermined field of a Session Initialization Protocol (SIP);
transmitting the specification information to a server through the SIP;
transmitting a message including a user equipment ID of the user equipment to the server;
receiving a plug-in software from the server, the plug-in software being configured to be installed on the user equipment and process the contents data to complement a process for the contents data at the user equipment; and
processing the contents data by executing the received plug-in software,wherein the server retrieves the specification information of the user equipment from database using the user equipment ID uniquely identifying the user equipment in a mobile wireless network, analyzes the retrieved specification information and the contents data based on the SIP to determine whether the user equipment needs the plug-in software for processing the contents data, and transmits the plug-in software to the user equipment when the user equipment needs the plug-in software, andwherein the specification information is selected from a group consisting of processer information, operating system information, resource information, and codec information.
