Abstract

According to one embodiment, a server apparatus for executing communication connection between a first terminal being connected to a first communication network, and a second terminal being connected to a second communication network, includes a memory, an acquisition module and a controller. The memory stores an electric quantity table and a media determining table. The acquisition module acquires remaining information of the battery from the first terminal. The controller refers to the electric quantity table and the media determining table to select a communication media based on the acquired remaining amount information of the battery and consumed electricity by the first terminal. When a request for the first terminal is received, controller assigns the selected communication media to the first terminal, when the battery remaining amount of the first terminal varies during communication, the controller re-determines to change the communication media.

Claims

1. A server apparatus for executing communication connection between a first terminal being connected to a first communication network, and a second terminal being connected to a second communication network differing from the first communication network, wherein the first terminal is assigned a terminal ID and is driven by electricity from a battery, the server apparatus comprising:

a memory configured to store an electric quantity table and a communication media determining table, wherein the electric quantity table showing a correspondence relationship among the terminal ID, a communicable communication media type, and consumed electricity for executing media communication, wherein the communication media determining table shows a correspondence relationship among the terminal ID, a battery remaining amount, and a terminal consumed electricity maximum quantity; and

a controller configured to acquire remaining amount information of the battery from the first terminal, and to refer to the electric quantity table and the communication media determining table to select a communication media based on the acquired remaining amount information of the battery and consumed electricity by the first terminal, when a request for the first terminal is received, and to assign the selected communication media to the first terminal, and to re-determine to change the communication media, when the battery remaining amount of the first terminal varies during communication,

wherein the memory stores the electric quantity table showing a correspondence between the communicable communication media type, a media type and the terminal consumed electricity maximum quantity,

wherein the controller determines the terminal consumed electricity maximum quantity based on the acquired remaining amount information of the battery and the communication media determining table, and determines the communication media based on the terminal consumed electricity maximum quantity and the electric quantity table.

2. The apparatus of claim 1, wherein

the controller is further configured to update content of the electric quantity table and the communication media determining table, when a data change request is issued.
