  • Publication number: 20070081455
    Abstract: A network component for classifying at least one IP flow for efficient quality of service realization in a network, where in one embodiment the network component includes a unit for detecting at least one IP flow from at least one IP packet. Upon detection of the at least one IP flow, the unit obtains predefined information from the at least one IP packet to determine a quality of service requirement that is associated with the at least one IP packet. The unit creates at least one other IP flow by multiplexing a plurality of IP packets with the same quality of service requirement into the other IP flow or demultiplexing the plurality of IP packets with different quality of service requirements into other IP flows, each of the other IP flows having a different quality of service requirement.

  • Publication number: 20070076667
    Abstract: A series of logical channel identifiers LCIDs, each associated with one radio link service profile RLSP, is stored in a local memory. The local memory is accessed whenever a LCID is taken into use for identifying an active logical channel, and each RLSP includes a set of radio link service parameters at least one of which is a quality of service parameter. A first data packet bearing a LCID and establishing a flow is received over a wireless logical channel. The local memory is accessed to determine if an RLSP is associated with the LCID of the first data packet. For the case where an RLSP is not associated with the LCID in the local memory, the LCID is associated with a designated default RLSP, and the first data packet is processed using the designated default RLSP. Predetermined and custom RLSPs are also described, as are methods, devices, programs, an integrated circuits embodying the invention.

  • Publication number: 20070053320
    Abstract: An apparatus that provides control channel signalling to a plurality of user terminals is provided. A definition unit is configured to define at least two allocation table formats. A selection unit is configured to select which allocation table format from the at least two allocation formats is to be used to construct an allocation table. A construction unit is configured to construct an allocation table based at least in part, on the selected allocation table format. A transmitter unit is configured to signal the allocation table to a plurality of user terminals, wherein the selected allocation table format is identified by a unified entry in the allocation table.

  • Publication number: 20050243735
    Abstract: A node selecting method in which a mobile node moving a plurality of nodes dispersedly arranged estimates a distance to a candidate node adjacent to the mobile node, and selects a node for next communication, is characterized in that the mobile node executes a first step of specifying, as the candidate node, a node present within a communication zone of the mobile node; a second step of calculating, for each specified candidate node, a ratio between the number of nodes present within a first region where the communication zone of the mobile node and a communication zone of the candidate node overlap each other, and the number of nodes present within second regions where the two communication zones do not overlap; and a third step of estimating the distance on the basis of the ratio.

  • Publication number: 20050182820
    Abstract: A method for controlling access to an electronic message comprising: specifying an addressee for an electronic message; determining a message context for the electronic message by specifying one or more conditions selected from a group comprising a time condition, a location of the addressee condition and at least one other condition concerning the environment of the addressee, wherein the message context defines conditions that must be satisfied before the addressee of the message can access the message; detecting the context of the addressee and comparing the context of the addressee with the message context; and enabling access by the addressee to the electronic message when the detected context of the addressee corresponds to the message context.

  • Publication number: 20050136903
    Abstract: A portable electronic device comprising: a user interface for providing an alert to a user; a memory for storing at least one value for each of a plurality of different context parameters; detection means for detecting a value for each of the plurality of different context parameters; and control means for determining when a detected value satisfies a rule involving a stored value for the same context parameter and for controlling the user interface to provide an alert. A portable electronic device comprising: a user interface for providing an alert to a user; detection means for detecting a context; a memory for storing a plurality of different trigger contexts; and control means for controlling the user interface to produce an alert when a detected context corresponds to a stored trigger context, wherein a context is defined by value(s) of one or more of a plurality of different context parameters.

  • Publication number: 20050129000
    Abstract: A node selecting method is characterized by comprising a first step of reserving a communication band on a route by seeking a communication route from a source node to a destination node through intermediate nodes by use of an ad-hoc on-demand distance vector (AODV) algorithm in a mobile ad-hoc network; a second step of storing information on communication bandwidth of a link route connecting each pair of neighboring intermediate nodes on the communication route in the intermediate nodes; and a third step of collecting information on available communication bandwidth of the communication route and transmitting it to the source node when a route reply is made from the destination node on the communication route toward the source node.

  • Publication number: 20050063337
    Abstract: A node selecting method in which a mobile node moving among a plurality of nodes substantially uniformly dispersedly arranged selects a candidate node for next communication, is characterized in that the mobile node executes a first step of specifying nodes present within the communication zone of the mobile node; a second step of counting the number of overlaps between the communication zone of the specified node and the communication zones of the other specified nodes for each specified node; and a third step of selecting, as the candidate node for communication, a specified node in which the largest number has been counted.

  • Publication number: 20040186890
    Abstract: A device for transmitting a message for reception by another device, comprising: a processor for adding location information to the message, before transmission, wherein the location information identifies an area within which the message is to be hosted for reception by the other device; and a transmitter for transmitting the message, with the location information.
