摘要： An improved scheduling mechanism usable for a data transmission in a packet based network is provided. A plurality of connections is detected, and for each of the connections, a buffer occupancy level is determined. Then, the connections having a smaller buffer occupancy level are prioritized in comparison to the other connections, and packets of the plurality of connections are scheduled on the basis of the result of the prioritizing. The scheduling mechanism is implemented in a network element of the packet based network or in a sender and receiver.

摘要： A method of relocating the header compression context in a packet network which transmits packets having compressed headers. A connection is established between a mobile terminal and a first network entity and context information used with compression and decompression of the headers of the packets is stored at the mobile terminal and the first network entity. The context information updating is stopped in the mobile terminal and in the first network entity and after that, a snapshot of the compression and decompression context information is taken and stored in the first network entity. The connection between the first network entity and the mobile terminal is changed to a connection between the mobile terminal and a second network entity. The context information snapshot stored by the first network entity is transferred to the second network entity to be stored therein as the context information of the second network entity. The stored context information at the mobile terminal and the second network entity is then used for compression and decompression of the headers of the packets.

摘要： A mobile station (100) and a compression/decompression node in a wireless network (5), preferably the GGSN 30 (30), agree on whether to apply compression/decompression, and what compression/decompression scheme to use either by pre-configuration (when the GGSN 30 is in the home network of the mobile terminal) or by signalling (when the GGSN 30 is in a visited or a roamed-to network). Additional information, such as a profile-specific dictionary, may be used to increase the compression efficiency, particularly during start-up. Dynamic data can also be accommodated. The compression/decompression may be turned on and off on a packet-by-packet basis, depending on whether the compression actually results in a smaller packet. A compressed/uncompressed indicator bit or bits can be inserted explicitly on a per packet basis, and/or the compressed/uncompressed indication can be derived implicitly. A desired data compression/decompression algorithm, or any desired Proprietary Feature, can be signaled, possible without requiring standardization changes, by using a Packet Data Protocol PDP Context Activation message with a predetermined Access Point Name (APN) message information element that is sent from a first network element to a second network element for at least identifying the desired compression/decompression algorithm. It another embodiment, for the case where Proprietary Feature capability is exchanged between a RAN and a UE network element, a transmission of an extension to a UE Capability Enquiry message is sent to the UE for identifying the Proprietary Feature.

摘要： This invention provides an improved address management scheme in a mobile router (MR) that connects a mobile network into the Internet via an access network. The MR performs neighbor advertisement on behalf of mobile network nodes (MNNs) within the mobile network so that packets directed towards the MNNs are routed correctly to the MR, and then to the corresponding MNN, while maintaining standard address management procedures, such as IPv6 address management procedures, in the access network and in the mobile network.

摘要： Apparatus, and an associated method, facilitates authentication of a mobile station operable in a 3G cellular communication system having a core network and a plurality of access networks. A standard signaling protocol is used to communicate between an access network and the core network. When a request for authentication of a mobile station is generated, a signaling protocol message is generated at a proxy of the access network within which the mobile station is to be authenticated. Detection of the authentication request is made at the proxy, and a message is generated at the proxy which includes indicia associated with the authentication center associated with the access network. The signaling protocol message is sent to the core network, and the information indicia contained therein is used to facilitate authentication procedures to authenticate the mobile station.

摘要： A method, computer program, and apparatus for allowing endpoints to move between zones of a packet-switched network. In the invention, a communication between local and remote endpoints are established via a first gatekeeper, which services a first zone of the packet-switched network, when the local endpoint is at a location serviced by the first zone of the packet-switched network. When the local endpoint moves to a location serviced by a second zone of the packet-switched network, subsequent to the initial hand-off, communication between the local and remote endpoints is maintained via the first gatekeeper and a second gatekeeper which services the second zone of the packet-switched network, by performing an initial hand-off communication control functions from the first gatekeeper to the second gatekeeper. When the local endpoint further moves to a location serviced by a third zone of the packet-switched network, communication between the local and remote endpoints is maintained via the first gatekeeper and a third gatekeeper, which services the third zone of the packet-switched network, by performing a subsequent hand-off of communication control functions from the second gatekeeper to the third gatekeeper.
