Embodiment Construction

[0028] According to one embodiment, the present invention provides a system and method for transmitting / receiving paging information in a mobile communication terminal, which can effectively reduce power consumption when the terminal is in an idle state. This can be achieved by adding an indicator for transmission in the broadcast channel (BCH), which indicates whether the paging information is transmitted through the PICH (Paging Indicator Channel). Various components and processes that are known or understood by those skilled in the art will not be described in detail.

[0029] image 3 is a flowchart representing steps involved in a method for transmitting and / or receiving paging information in UMTS (Universal Mobile Telecommunications System) according to an embodiment of the present invention. The method includes using UTRAN (UMTS Terrestrial Radio Access Network) to set an indicator indicating whether to transmit paging information through PICH (step S310). Then, the U...

Abstract

A method for transmitting / receiving paging information in a mobile communication system includes transmitting the information through a broadcast channel, and then receiving the paging information through a paging indicator channel based on an indicator transmitted through the broadcast channel. The indicator indicates whether paging information is transmitted through the paging indicator channel. It is also possible to transmit reception time point information and reception cycle information to facilitate reception of paging information. By transmitting the indicator through the broadcast channel, the mobile terminal can save power because it only performs a "wake-up" function when the indicator has a predetermined value representing paging information transmitted through the paging indicator channel.

Description

technical field [0001] The present invention relates to a mobile communication system, and more particularly, to a system and method for transmitting / receiving paging information in a mobile communication system. Background technique [0002] Mobile communication systems allow a user to wirelessly page another user as well as wirelessly connect to communicate anytime anywhere. This has been achieved by controlling switching operations performed by a Mobile Switching Center (MSC), while traveling in a service area managed by a Base Station (BS). In addition to voice signals, mobile communication-related technologies have allowed data and multimedia signals to be transmitted. [0003] Various mobile communication systems have been developed, including CDMA (Code Division Multiple Access), TDMA (Time Division Multiple Access), FDMA (Frequency Division Multiple Access), and GSM (Global System for Mobile Communications) systems. The ITU (International Telecommunications Union) ...
