Abstract

A User Equipment (UE) category handling method and an apparatus for handling late version UE category attached to an early release version network in a Long Term Evolution (LTE) system are provided. A communication method includes transmitting a terminal capability report message including multiple terminal categories, receiving a Radio Resource Control (RRC) connection reconfiguration message including a terminal category to be used by the terminal according to serving base station of the terminal, and communicating with the network using the terminal category received from the network. The UE category handling method and apparatus of the present invention allows the UE to report a network-adaptive UE category, thereby avoiding soft buffer problem caused by version information mismatch and facilitating communication with the network without malfunctioning.

Description

technical field [0001] The present invention relates to wireless communication systems. More particularly, the present invention relates to a method and an apparatus for handling a new version user equipment (UE) category in an early release network in a long term evolution (LTE) system. Background technique [0002] Mobile communication systems are developed to provide voice communication services on the move to subscribers. With the rapid advancement of technology, mobile communication systems have evolved to support high-speed data communication services in addition to standard voice communication services. However, resource shortages in current mobile communication systems and user demands for higher-speed services motivate evolution to more advanced mobile communication systems. [0003] Recently, the next generation mobile communication systems of the 3rd Generation Partnership Project (3GPP), Long Term Evolution (LTE) and LTE-Advanced (LTE-A) are being standardized....
