摘要： A content packet transmission control system in a mobile communication network supporting a multimedia broadcast/multicast service (MBMS) includes a broadcast/multicast service center (BM-SC) performing an inter-working operation with a gateway general packet radio service support node (GGSN) and managing the MBMS so that contents may be broadcasted/multicasted to a plurality of user terminals, and a content provider (CP)/multicast broadcast (MB) source server providing contents of an internal CP or contents of an external CP according to a broadcasting schedule of each MBMS. When the user terminal using a predetermined MBMS leaves a service area or requests to stop the service, the content packet transmission control system stops transmitting corresponding service contents, and transmits a service packet to a new user terminal requesting the service and the user terminal coming back to the service area.

摘要： A system and method for reassembling packets in a packet relay node are provided. A packet relay node located between a transmitting node (i.e., a source node) and a receiving node (i.e., a destination node) inspects received packets to see if they are fragmented packets and reassembles a series of packets decided to be fragmented packets into an original packet, thereby reducing overhead and radio resource waste caused by duplicate transmission of IP headers having the same fragmented-packet information.
