METHOD AND APPARATUS FOR DETECTING A SMALL DATA IN THE MOBILE COMMUNICATION SYSTEM

摘要

The present invention relates to a method and a device for searching the characteristics of data to be transmitted by a terminal, and carrying and transmitting small data in a control message. The method of transmitting data by the terminal according to the present invention comprises the steps of: generating IP data; determining whether the data has a size smaller than or equal to a preset reference size or corresponds to small data matching identification information on a preset service; and transmitting the IP data to a network as a control message through a connection management (CM) layer. [Reference numerals] (310) IP data to be transferred is generated; (320) IP data is matched with a small data packet filter?; (330) Transfer the IP data by using a control message; (340) Matched with the rest of the packet filter?; (350) Transfer to a network by using a bearer mapping the IP data; (360) Drop the IP data; (AA) Start; (BB) End
