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 method for scheduling packets from a plurality of radio bearers by a scheduler of a first layer includes calculating a virtual scheduling time for the radio bearers by using a packet delay variation of the radio bearers, and transmitting the packet of the radio bearer having the greatest virtual scheduling time from among the plurality of radio bearers to a second layer.

摘要:
A method for controlling and managing a bearer in a gateway of an IP-based mobile communication network is provided. A protocol message that must be sent between a mobility management entity and a gateway where a bearer exists is newly defined as context setup and IP allocation request/response messages, request/response messages for setup and release of a tunnel for service initiation and release, user equipment handover completion/completion acknowledgement messages, paging indication/response messages for a packet coming from a network, and multicast-service join/leave indication messages when the user equipment is powered on/off, resulting in high efficiency of signal protocol and efficient bearer management irrespective of separation or integration of physical nodes of the mobility management entity and the serving gateway.
