Abstract

A method and apparatus for enabling efficient use of radio resources by reducing an RLC PDU size in a mobile communication system supporting voice service over a packet network are provided. An RLC layer constructs an RLC PDU without inserting information indicating the start and end of an SDU or indicating the use or non-use of padding. The RLC layer sets an LI in a header to indicate inclusion of an intermediate SDU segment in the data field of the RLC PDU. Therefore, the resulting decrease of overhead arising from packet transmission facilitates the efficient use of limited radio resources.

Description

technical field [0001] The present invention generally relates to mobile communication systems supporting packet services. More particularly, the present invention relates to efficient use of radio resources by reducing the header size of Protocol Data Units (PDUs) transmitted over radio links. Background technique [0002] Today's mobile communication systems are evolving towards high-speed and high-quality wireless data packet communication systems. These systems are capable of providing data services and multimedia services in addition to traditional voice services. Universal Mobile Telecommunications Service (UMTS), a third-generation mobile communication system using Wideband Code Division Multiple Access (WCDMA) based on the European Global System for Mobile Communications (GSM) and General Packet Radio Service (GPRS), is provided to mobile subscribers or computer users A unified service that delivers packet-based text, digitized voice, and video and multimedia data ...
