Embodiment Construction

[0021] The techniques described below can be used in various wireless communication systems such as Code Division Multiple Access (CDMA), Frequency Division Multiple Access (FDMA), Time Division Multiple Access (TDMA), Orthogonal Frequency Division Multiple Access (OFDMA), Single Carrier Frequency Division Multiple Access (SC-FDMA), etc. CDMA can be implemented in a radio technology such as Universal Terrestrial Radio Access (UTRA) or CDMA-2000. TDMA can be implemented in radio technologies such as Global System for Mobile communications (GSM) / General Packet Radio Service (GPRS) / Enhanced Data rates for GSM Evolution (EDGE). OFDMA can be implemented in radio technologies such as Institute of Electrical and Electronics Engineers (IEEE) 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), IEEE 802-20, Evolved UTRA (E-UTRA), and the like. IEEE802.16m is an evolution of IEEE 802.16e, and provides backward compatibility with IEEE 802.16-based systems. UTRA is part of the Universal Mobile Telecomm...

Abstract

A method and apparatus for performing application-specific access control in a wireless communication system are provided. A user equipment (UE) receives access control-related information from the network, identifies initiation of a specific application, and determines whether to allow an access attempt for the specific application based on the received access control-related system information. Therefore, the UE can determine whether to skip the access control barring (ACB) check for a specific application, or whether to skip the random access fallback for a specific application.

Description

technical field [0001] The present invention relates to wireless communication, and more particularly, to a method and apparatus for performing application-specific access control for public safety and / or mission critical push-to-talk (MCPTT) in a wireless communication system. Background technique [0002] The 3rd Generation Partnership Project (3GPP) Long Term Evolution (LTE) is a technology for realizing high-speed packet communication. A number of proposals have been proposed for LTE goals including aiming at reducing user and provider costs, improving service quality, and expanding and enhancing coverage and system capacity. 3GPP LTE requires reduction of cost per bit, increase of service availability, flexible use of frequency band, simple structure, open interface, and appropriate power consumption of terminals as high-level requirements. [0003] Recently, there has been a growing interest in ensuring that the public has the ability to receive timely and accurate al...
