METHOD AND APPARATUS FOR ESTABLISHING RADIO BEARER FOR POINT-TO-MULTIPOINT MULTIMEDIA SERVICE IN MOBILE COMMUNICATION SYSTEM

摘要

A method and apparatus for establishing a radio bearer of a point -to-multipoint multimedia service by utilizing a reference configuration of radio bearer parameters for quickly establishing a radio bearer when a mobile terminal moves between cells. By configuring radio bearer parameters for a specific point- to- multipoint services by utilizing a references configuration such that the same, or equal value, protocol and channel parameters are set for each cell, different cells in a communication system in which a specific point-to-point is provided are able to configure the radio protocol entities, channels, and radio bearer at the same time by utilizing the same parameter values, thereby minimizing delay in establishing a radio bearer and minimizing data loss occurring during handover, conserving network resources, and enhancing reception performance via soft combining
