METHOD AND APPARATUS FOR PAGING THAT CONSIDER CARRIER AGGREGATION ENVIRONMENT IN MOBILE COMMUNICATION SYSTEM

摘要

PURPOSE: A paging method considering carrier aggregation environment in a mobile communication system is provided to control the unit frequency selection through a load control in a base station paging. CONSTITUTION: A terminal confirms a CC set within a paging message(220). If the CC set is same with the CC set of the terminal, the terminal performs a random access through the main CC of the CC set(222~226). The terminal acquires the UL(UpLink) synchronization of the sub CC within the CC set(228). The terminal transmits a connection configuration completion message to the base station(230).
