A positional information managing device includes a processor. The processor is configured to manage first positional information of a first mobile device communicating with a network. The processor is configured to associate device information of a second mobile device connected to the first mobile device with the first positional information. The second mobile device communicates with the network through the first mobile device.

Positional information managing device, mobile terminal, and mobile device

A management apparatus that identifies a candidate for improving communication quality in a wireless communication system including a base station and a mobile station, the management apparatus comprising: an obtainer that obtains measured communication quality information and positional information from the mobile station; a communication quality estimator that estimates a communication quality based on the positional information obtained from the mobile station; a communication path determiner that identifies a communication path using the estimated communication quality estimated and the measured communication quality information; and a communication quality improvement candidate determiner that identifies the candidate for improving communication quality related to the communication path determined, the candidate being based on communication quality. A method and a program for identifying a candidate for improving communication quality, an apparatus, a method, and a program for determining a communication path, and a wireless communication system are also provided.

Management apparatus and method for identifying candidate for improving communication quality; apparatus and method for identifying communication path; non-transitory computer-readable storage medium storing such programs; and wireless communication system

A radio access system includes a controlling apparatus that when the terminal apparatuses to which delivery data is to be delivered are concentrated in a particular area, groups the terminal apparatuses as a terminal apparatus group, selects a representative server terminal apparatus from the terminal apparatuses, creates data map information indicating a delivery rule for delivering the delivery data from the representative server terminal apparatus to another terminal apparatus, adds information for identification of the representative server terminal apparatus to the data map information, transmits the group information and the data map information to the terminal apparatuses, and instructs a delivery data server to deliver the delivery data to the representative server terminal apparatus; and a terminal apparatus that obtains the delivery data by communicating, in accordance with the received data map information, with the another terminal apparatus within the terminal apparatus group included in the received group information.

Radio access system, controlling apparatus, and terminal apparatus

A communication control apparatus includes an acquirer that acquires operation information of a moving object having a shielded space therein, and a controller that controls at least one of a channel between a first base station installed in a car in the moving object and a second base station installed on each floor where the car is stoppable, transmission power of the first base station and transmission power of the second base station, and location information for locating a position of a mobile terminal for each floor where the car is stoppable, on the basis of the operation information.
