The present invention provides a mobile terminal, resource allocation manager and communication control method for sustaining the standby time to a time equivalent to the standby time of a communication device in which only a single radio interface is activated, without missing an opportunity of radio communication under good communication conditions. A mobile terminalcomprises a first communication section, a second communication section, a receiving activation sectionfor activating a second receiving function for the second communication sectionas a result that the first information is received by the first communication section, an information transmission sectionfor sending terminal identification data of the mobile terminalas a result that the second receiving function is started up by the receiving activation section, and a switching request sectionfor selecting the first communication sectionor the second communication sectionas a communication section for receiving information sent by the radio communication station which received the terminal identification data from the information transmission section, based on the terminal identification data, and switching a receiving function to be activated.

Mobile terminal, resource allocation manager, and communication control method

A mobile terminal configured to constitute an ad hoc network together with a plurality of other terminals, the mobile terminal includes a packet relay unit configured to execute a relay operation of relaying a packet transferred between the other terminals. A packet transmitter is configured to execute a transmission operation of transmitting a packet generated in the mobile terminal to any one of the other terminals. A power supply manager is configured to execute a power supply control operation. A coordination controller is configured to cause the relay operation and the power supply control operation to be coordinated with each other, and to selectively control whether each of the relay operation, the transmission operation and the power supply control operation is executed.

Mobile terminal, wireless communications system and mobile terminal control method

HLR installed in an environment in which there are a plurality of mobile communication networks, is provided with a whole managed object manager for storing and managing subscriber number IDs and HLR information to manage the subscriber number IDs, in correspondence to each other; a subscriber data manager for storing and managing subscriber number IDs registered as managed objects of the host HLR and subscriber data of the subscriber numbers in correspondence to each other; and a determination controller for determining whether subscriber management information (subscriber number IDs and subscriber data) of managed objects in the host HLR is to be transferred to another HLR, based on criterion information such as current subscriber management information volume and accommodation capacity information, and for, when the transfer is necessary, determining a recipient HLR and subscriber management information of a transferred object, based on the criterion information in each HLR and a predetermined standard.

Location register and accommodation transfer control method

Various services for a mobile communication network or an IP network are implemented by processing necessary information suitably in accordance with a service type so as to exchange the information to a service control device and transmitting the results of the service process by the service control device to the mobile communication network or the IP network, for a service request from the mobile communication network or the IP network. A gateway device of the present invention retains a signal defining various rules or policies received from the service control device, judges a service type and a destination requested from the service request signal by the various rules or policies for the service request signal transmitted from a communication terminal of the mobile communication network or the communication terminal of the IP network, performs protocol conversion on the service request signal in accordance with the service type, and transmits the service request signal to the corresponding destination.

Gateway apparatus, and method for processing signals in the gateway apparatus

A communication control unit receives destination terminal identification information and communication software from a source communication terminal. The communication control unit installs software. Address information of another communication control unit is acquired from an externally located apparatus. The another communication control unit can be connected to a destination communication terminal corresponding to the destination terminal identification information. The destination terminal identification information and software identification information uniquely identifying the installed software is transmitted to an address of the another communication control unit included in the address information. Software identification data is transmitted to the another communication control unit. Software corresponding to the software identification data is received and installed to control a network connection of the another communication control unit.
