A method and apparatus is disclosed herein for estimating travel behavior in a mobile network. In one embodiment, the method comprises receiving event data indicative of user equipment location, pre-processing received event data to produce pre-processed data, performing straight line interpolation on pre-processed data of one or more individuals in the population to estimate intermediate positions of a trajectory of each of the one or more individuals from a first position to a second position, and counting a number of individuals in population at a given time and at a given area.

Dynamic travel behavior estimation in mobile network

Methods and apparatuses are disclosed herein for population tracking, counting and/or movement estimation. In one embodiment, the method comprises receiving mobile phone operational data indicative of user equipment location, where the event data includes location area update messages and periodic registration messages; and performing travel estimation based on the mobile phone operation data, including performing interpolation on data associated with one or more individuals in a population to estimate intermediate positions of a trajectory of each of the one or more individuals for a specified time period based on a shortest path mesh sequence estimation algorithm.

System and method for population tracking, counting, and movement estimation using mobile operational data and/or geographic information in mobile network

In a proxy terminal or server a path setting can be performed by a server apparatus and a path setting that includes, as a relay point, a proxy terminal arbitrarily specified by a user or the proxy terminal located in a local network to which the user belongs, without adding any function to a user terminal. The proxy terminal includes a terminal group information generator unit configured to generate terminal group information that includes a user terminal identifier and a proxy terminal network identifier as a pair, and to transmit, to a server apparatus, the generated terminal group information.

Proxy terminal, server apparatus, proxy terminal communication path setting method, and server apparatus communication path setting method

A server devicerequests a client deviceto execute one of a plurality of computations having different degrees of difficulty. Client deviceidentifies, based on an amount of computation required for each of said plurality of computations, a computation to be executed and executes the computation. Client device, when requesting execution of a given process to server device, transmits a result of the computation to server device. Server device, when the computation result is correct, executes a predetermined process according to a priority based on an amount of the computation.

Server device, client device, and process execution method

When a connection is established between a client device and a server device, a first message requesting establishment of a downlink connection is transmitted from the client device to the server device, and a server device which has received the first message is caused to transmit to the client device a second message requesting establishment of an uplink connection. The client device which has received the second message is caused to transmit to the server device a third message acknowledging the second message and requesting establishment of the downlink connection. The server device which has received the third message is caused to establish the downlink connection based on the content of the third message.

Server device, method for controlling a server device, and method for establishing a connection using the server device

A reception notification control method is provided in which an information server that stores information addressed to reception terminals and performs reception notification, via a network apparatus, on each of the reception terminals to which the information stored in the information server is addressed. After receiving, via the network apparatus, a predetermined connection request from a reception terminal to which stored information is addressed, the information server performs the reception notification on the reception terminal.

Reception notification control method and system

A relay device, when it relays data blocks transmitted in succession from a transmitter deviceto a receiver device, is caused to identify a state code showing a state of a communication resource used when the data blocks are transferred. Relay devicedivides the identified state code into portions of a predetermined data size and writes the divided portions into a predetermined area of the data blocks. Receiver devicetransmits to transmitter devicean acknowledgement containing the same data as is written in a predetermined area of the received data block. Transmitter device, upon receipt of the acknowledgement, reads the state code that is divided and written in the acknowledgement and increases or reduces the number of data blocks on the basis of the state code.

Communication control method and system

A transmitter device, in transmitting a predetermined number of data blocks out of a plurality of data blocks to a receiver devicevia a relay device, divides and writes into data blocks transmitted in succession, a request code for requesting relay deviceto relay remaining data blocks. Relay device, in the case of accepting the request shown in the request code that is divided and written in the data blocks transmitted from transmitter device, notifies the acceptance of the request to transmitter device. Transmitter device, upon receiving the notification, then transmits the remaining data blocks in succession to relay device

A transmitter device which transmits a data block containing a unique number to a receiver device is caused to transmit subsequent segments to be transmitted after a transmitted segment up to a predetermined number in a case of receiving, after retransmitting the transmitted segment, an acknowledgement containing a number of the retransmitted data block.

Transmitter device for controlling data transmission

A transmitter device which performs window control in transmitting data for transmission through a communication network is caused to identify a mode of window control to be performed based on a communication condition under which the data transmission is performed, so as to transmit the data for transmission by performing the window control in the identified mode.

Transmitter device and relay device for performing data transmission control

A management server includes a determination unit and a notification unit. The determination unit determines a communication network to which a mobile terminal connectable to a plurality of the communication networks by one telephone number is connecting. The notification unit issues a notice on the communication network connecting to the mobile terminal based on a result of the determination by the determination unit.

Management server and mobile terminal

A service discovery system including a client terminal and a service providing device which provides data or a function to the client terminal, including: a service request unit which generates a message requesting a service of the service providing device; a communication unit which sends the message generated by the service request unit to the service providing device and which receives from the service providing device a problem imposing a load on the client terminal; and a solution unit which solves the problem.

Service discovery system, client terminal, service providing device, and service discovery method

Plural terminal devices are arranged under a relay apparatus. The relay apparatus includes a mobile communication network connection unit, a packet switching network connection unit, and an emergency call determination unit. The emergency call determination unit determines whether or not the calls originated from the terminal devices are emergency calls, and when the calls are the emergency calls, connects the emergency calls to the mobile communication network connection unit. When the calls are the emergency calls, the mobile communication network connection unit connects the emergency calls to the mobile communication network by issuing thereto a notice on an identification number of the relay apparatus, the identification number being stored in an IC card attached to the relay apparatus.
