摘要： Upon detection of an environmental change in a neighborhood, a cellular phone makes selections of a communication device and a communication path, which are used for a communication. A communication packet transmitted from a communication corresponding terminal is distributed to the cellular phone that is the destination of the communication packet, and a PC physically positioned in the neighborhood of the cellular phone, according to the results of the selections, thereby switching from a communication using only the cellular phone to a communication using both the cellular phone and the PC.

摘要： An IP connection processing device and, more particularly, an IP connection processing device that, upon completion of user authentication, initiates a connection to an IP network in a designated area constructed by a wireless LAN or the like. The IP connection processing device, which processes the connection to the IP network that requires user authentication for connection to the network, includes components for: detecting authentication completion; acquiring an authentication result; and initiating or resuming the IP connection processing upon detection of the authentication completion. The IP connection processing device, upon detection of the authentication completion, requests IP address information from the IP network, and acquires an IP address of its own based on the information returned by the IP network.

摘要： A reception unit receives data from communication apparatuses. A transmission unit transmits data to the communication apparatuses. A control unit determines, in an adaptive way, which modulation and coding schemes to use to transmit and receive data. At a first stage, a modulation and coding scheme with a low transmission rate or a modulation and coding scheme that minimizes power requirements is selected from among a plurality of candidates therefor. At a second stage, the modulation and coding scheme of at least one of the communication apparatuses is changed to another scheme having a higher transmission rate, when it is impossible to allocate sufficient resources for the modulation and coding schemes selected at the first stage.

摘要： When a failure occurs in a node managing the location information of mobile node MN, it is possible to resume packet transfer from correspondent node CN to mobile node MN after the node is restored from the failure, in a mobile communication network. The mobile communication network includes a plurality of nodes including a home agent, a correspondent node, and a mobility anchor point connected to the network, wherein each node produces a duplication of a binding cache on receipt of location registration information from a mobile terminal, maintains and manages the duplication of the binding cache, and on restoration of the node from a failure, each node obtains the contents of the binding cache stored before the node failure from the duplicated binding cache.
