Link Connection Control Protocol Incarnation Apparatus and Method for IP Multicast/Broadcast packet transmistting in Mobile Network

摘要

PURPOSE: A link connection control protocol embodying apparatus for transmitting IP multicasting/broadcasting packet data and a method thereof are provided to transfer data received in a physical layer to an upper data layer by transmitting a cellular multicasting/broadcasting packet between a base station and a mobile communication terminal in a mobile communication network. CONSTITUTION: A base station(104) divides and transmits IP multicasting/broadcasting packet data from an internet host or an IP packet multicasting/broadcasting packet server through a base station controller/packet controller into a radio frame. A mobile communication terminal(105) combines the radio frame from the base station(104) and forms a P packet multicasting/broadcasting packet. A repeat transmission request message based multicasting/broadcasting link connection control protocol confirms a frame transmission in a radio link between the base station(104) and the mobile communication terminal(105).
