Abstract: When a communication apparatus (server device) that includes wireless access means and can send content data by using the wireless access means starts sending content data, it calculates a communication band that remains available for the server device to perform communication, so that any content that has a rate equal to or greater than the remaining communication band may not be publicized open to and may not hence be sent to a client device.

Abstract: An electronic apparatus includes a plurality of communication units including a first communication unit which communicates via a first communication network and a second communication unit which communicates via a second communication network. The electronic apparatus acquires presence information indicating a communication state of a communication apparatus from a presence server managing a communication state of a communication apparatus on a communication network, via at least one communication network. The electronic apparatus acquires presence information of an alternative communication apparatus being as a communication apparatus which communicates via the second communication network in place of the second communication unit included in itself. The electronic apparatus determines as to whether the alternate communication apparatus is in an online state, based on the acquired presence information. The electronic apparatus suppresses electric power to be consumed by the second communication unit, when the alternate communication apparatus is in an online state.

Abstract: A communication terminal optimally switches between the use of multicast reception and unicast reception, in consideration of the mobile radio environment of each terminal. For example, received signal strength indicator information is acquired at a received signal strength indicator information acquisition time calculated using a content reception time. Either multicast reception or unicast reception is selected according to the acquired received signal strength indicator information and content reception is performed. An optimal reception system can be selected and reception failure can be reduced. In addition, by performing a dynamic switching of reception methods as such, the base station-end can perform multicast delivery rather than unicast delivery when possible to communication terminals in favorable mobile radio environments, thereby significantly reducing the traffic load placed on communication paths.

Abstract translation: 考虑到每个终端的移动无线电环境，通信终端在多播接收和单播接收的使用之间最佳地进行切换。 例如，在使用内容接收时间计算的接收信号强度指示符信息获取时间获取接收信号强度指示符信息。 根据获取的接收信号强度指示符信息选择多播接收或单播接收，并且执行内容接收。 可以选择最佳的接收系统，并且可以减少接收失败。 另外，通过执行接收方法的动态切换，基站端可以在有利的移动无线环境中的通信终端可以执行组播传送而不是单播传送，从而显着减少通信路径上的业务负担。

Abstract: When a terminal-status detecting unit detects a predetermined terminal status with communication over a first mobile communication system being enabled by a first mobile communication unit, a control unit causes a second mobile communication system to start a process of acquiring a second mobile communication system to set communication via the second mobile communication system in an enabled status.
