The present invention relates to a wireless communication system, and more particularly, to a method and apparatus for supporting discontinuous reception (DRX) of a user equipment (UE).
2. Background Art
Universal mobile telecommunication system (UMTS) is a 3rd generation (3G) asynchronous mobile communication system operating in wideband code division multiple access (WCDMA) based on European systems, global system for mobile communications (GSM) and general packet radio services (GPRS). A long-term evolution (LTE) of UMTS is under discussion by the 3rd generation partnership project (3GPP) that standardized UMTS.
The 3GPP LTE is a technology for enabling high-speed packet communications. Many schemes have been proposed for the LTE objective including those that aim to reduce user and provider costs, improve service quality, and expand and improve coverage and system capacity. The 3GPP LTE requires reduced cost per bit, increased service availability, flexible use of a frequency band, a simple structure, an open interface, and adequate power consumption of a terminal as an upper-level requirement.
FIG. 1 shows LTE system architecture. The communication network is widely deployed to provide a variety of communication services such as voice over internet protocol (VoIP) through IMS, packet data, broadband, and so on.
Referring to FIG. 1, the 3GPP LTE system architecture includes one or more user equipment (UE), an evolved-UTRAN (e-UTRAN) and a core network. The e-UTRAN includes one or more base stations, providing radio access services to the UEs and communicating with the UEs. The radio access service and system may be referred to as a system. The e-UTRAN may include one or more Node-Bs, for example.
A current working assumption is to include in 3GPP LTE systems, support for international roaming and access to home public land mobile network (HPLMN) in idle mode. In the current working assumption, the idle mode implies that a UE in idle mode be359ba680
