Disclosed are an SIP-based user mobility service providing apparatus and method using user position information obtained by a sensing apparatus. When a user enters a specific region, a gateway including a sensing management module carries out SIP registration for several terminals existing in the specific region in place of user agents of the terminals. The sensing management module transmits an SIP registration message to an SIP proxy server and notifies the terminals of the completion of SIP registration. Then, the user receives a call using the same kind of a terminal as a specific terminal previously set on the basis of a user's preferences among the terminals in the specific region.

There is provided a method for a multimedia broadcast/multicast service (MBMS) announcement to provide a service announcement document in a broadcast multicast service center (BM-SC) of a MBMS system, including the steps of: generating a service announcement document; searching a service announcement area; setting a session for providing the service announcement document to the searched service area by setting a MBMS multicast bearer; transmitting a corresponding service announcement document to the service announcement area, wherein the service announcement document includes an announcement area directories according to service announcement areas, and the announcement area directory includes service directories according to services provided to corresponding service announcement areas as a lower directory.
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 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.
