Abstract:
Provided is a management system for solving the problem of an increase in the load on a network when managing the location of a mobile object in the cloud. The management system includes: a mobile object for estimating the location of a host device after a predetermined time has elapsed, using a predetermined motion model; and a management device for estimating the location of the mobile object after the predetermined time has elapsed, using the predetermined motion model. The mobile object transmits information relating to the location of the host device to the management device in response to the fact that the error between the location of the host device measured after the predetermined time has elapsed and the estimated location of the host device has exceeded a predetermined threshold value.
Abstract:
In a communication system, when a path is switched along with communication apparatus switchover, a packet sent/received via this path may be lost. A communication system according to the present invention is characterized by including: a first network node capable of processing a communication session related to a terminal; and a communication apparatus that forwards data related to the terminal via the communication session established with the first network node, wherein the communication apparatus is capable of sending a control signal indicating termination of the communication session in response to switchover from the first network node to a second network node having a function corresponding to the first network node.
Abstract:
A technique is provided that makes it possible to diversely control a radio network based on status other than that of the radio network. A network control apparatus according to the present invention includes: a first means for acquiring status related to a second network, which is accessed via a first network, in which each base station is separated into a radio section and a baseband processing section; and a second means for controlling a resource to be allocated to the baseband processing section based on the status.
Abstract:
The base station includes: a position information acquisition unit that acquires position information of the base station; a subordinate terminal information sharing unit that shares the position information of the base station and subordinate terminal information of the base station with one or more peripheral base stations in a vicinity of the base station, and acquires position information for each of the peripheral base stations and subordinate terminal information for each of the peripheral base stations; a communication request acceptance unit that accepts a communication request from a first communication terminal being subordinate to the base station to a second communication terminal being subordinate to one of the peripheral base stations; and a path setting unit that sets a communication path from the first communication terminal to the second communication terminal, based on position information of the base station, position information of each peripheral base station, and subordinate terminal information.
Abstract:
A positioning system includes a terminal device that measures a position of the terminal device by using a first positioning method using first positioning signals transmitted from satellites included in a global positioning system and a second positioning method different from the first positioning method and a server device that transmits a positioning method setting instruction including a positioning method based on the position of the terminal device to the terminal device, in order to achieve continuous positioning without depending on a reception state of radio waves transmitted from the satellites included in the global positioning system.
Abstract:
A communication device for offloading communication traffic is characterized by including: first means for identifying an attribute of a communication terminal based on a message transmitted by the communication terminal to connect to a wireless network; and second means that can instruct the communication terminal to reconnect to a base station corresponding to the attribute according to the identified attribute.
Abstract:
In a communication system, when a path is switched along with communication apparatus switchover, a packet sent/received via this path may be lost. A communication apparatus according to the present invention is characterized by including: a first means capable of operating a first network node on a virtual machine; and a second means capable of forwarding a control signal for terminating communication performed via a communication session established between the first network node and a third network node, to a virtual machine operating a second network node, in response to switchover from the first network node to the second network node corresponding to the first network node.
Abstract:
A base station for offloading communication traffic includes: first means for receiving from a communication terminal a message requesting a connection with a wireless network; and second means for determining whether or not a connection between a base station which has received the message from the communication terminal and the communication terminal is possible based on a terminal attribute identified by the message.

A communication device for offloading communication traffic includes: first means for identifying an attribute of a terminal based on information included in a message transmitted by the terminal to connect to a wireless network; and second means for determining whether or not to connect a base station that has received the message from the terminal and the terminal based on the identified attribute, wherein the second means is capable of transmitting the message transmitted by the terminal having a predetermined attribute to a virtual network node operated by a virtual machine.
Abstract:
A technique is provided that makes it possible to diversely control a radio network based on status other than that of the radio network. A network control apparatus according to the present invention includes: a first means for acquiring status related to a second network, which is accessed via a first network which wirelessly transfers data; and a second means for controlling at least one base station of the first network based on the status so as to change a relation of connection between the at least one base station and the second network.
