摘要： Apparatus, and an associated method, for facilitating communication of a data block to a mobile station (12) when a handover of communications is effectuated. A segmentation and distribution unit (78) is positioned at a base station gateway (52), and the base station gateway (52) is coupled to both a first target entity (56) and a second target entity (66). Portions of the data block are provided to the first target entity (56) to be communicated to the mobile station (12). When a handover of communications is effectuated, the buffered portion of the data which has not yet been successfully delivered to the mobile station (12) is forwarded to the second target entity (66). And, other portions of the data block, not yet delivered to the first target gateway (56) are, thereafter, provided directly to the second target entity (66).

摘要： The invention proposes a method for controlling a connection between a first network node and a second network node, wherein the connection is controlled by a packet filtering function filtering packets such that a packet is discarded in case a source address and/or a destination address do not comply with a filtering rule, wherein the packet filtering function is configured at a connection set up, and at least one of the first or second network node is adapted to change its address, the method comprising the steps of informing the packet filtering function about the new address of the network node having changed its address, and updating the packet filter of the packet filtering function by using the new address of the network node having changed its address. The invention also proposes a corresponding network system comprising at least a network node and a packet filtering network element. Furthermore, the invention proposes a corresponding packet filtering network device.

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： A method and system handles at least one connection to at least one terminal in an access network. The access network includes a radio interface and at least one router. A link layer address is assigned to the at least one terminal, and a cell-specific radio link identifier is used at the radio interface for identifying a radio link to the router. An identifier for identifying the terminal or terminals preferably includes an RLI field for identifying the radio link, and a LLA Mapping field for identifying the terminal.

摘要： A “loose ACK”method by which a radio access network of a cellular network monitors wireless transmission of packets according to a layered protocol including a radio layer (near the physical layer) and an upper layer, the method including: a step (23) of slow release, in what is called normal buffer management, in which the upper layer removes from a buffer maintained by the upper layer the oldest packet in the buffer when the buffer is full and a new packet arrives, and does so independently of whether the packet being removed has been acknowledged by the radio layer of the terminal, and a step (24) of local acknowledgement in which the radio layer sends an acknowledgement to the upper layer on the occurrence of a predetermined event. The local acknowledgement can trigger either special mode buffer management or release of the buffer to a target (entity or layer).

摘要： For reducing IP level signaling and radio resource load during the attachment or update, e.g. L3 or IP attachment/update, of a mobile unit to a cellular wireles s communication network, preferably an IPv6 based network, wherein access net­work elements and routing network elements are provided, an identification ele­ment is transmitted from the mobile unit to one of the access network elements. The identification element indicates a current attachment of the mobile unit to one of the routing network elements. The transmitted identification element is checked so as to determine whether the access network element is provided with a connection to the one routing network element. Furthermore, it is checked whe­ther a network status still allows the usage of this routing network element by the mobile unit. If both of these criteria are fulfilled, the attachment or up­date procedure between the mobile unit and the access network element is comple­ted while the attachment of the mobile unit to the routing network element is retained unaffected. This process is executable when the mobile unit moves from one cell area to another cell area, or when a network status concerning the attachment of the mobile unit has changed, or when a predetermined period of time is expired while the mobile unit remains in the same cell area.
