1. A communication system comprising:
- an information server capable of performing communication in first and second communication modes; and
a communication apparatus which is provided as an integrated unit and is capable of performing communication in the first and the second communication modes, the communication apparatus including;
communication circuitry capable of performing communication with the information server in the first and the second communication modes to receive information sent from the information server in response to an information acquisition request generated by the communication apparatus and communicated to the information server via the communication circuitry;
an output device for outputting the information received from the information server;
a connection information storage section; and
a communication mode switching control section for controlling the switching of communication mode with the information server from the first communication mode to the second communication mode by storing into the connection information storage section connection information based on a condition of communication connection of the communication apparatus and the information server in the first communication mode at a time of the switching, releasing the connection of the communication circuitry with the information server in the first communication mode in a state in which a connection of the communication apparatus and the information server in the second communication mode is not established, establishing a connection with the information server in the second communication mode in a state in which a connection of the communication apparatus and the information server in the first communication mode is not established, and restoring the condition of communication connection based on the stored connection information.

Abstract
An example communication apparatus is capable of performing communication with an information server in first and second communication modes. After establishing a connection with the information server in the first communication mode and receiving an information acquisition request, the communication apparatus stores a condition of the communication connection with the information server as connection information, disconnects the communication in the first communication mode, establishes a connection with the information server in the second communication mode, and restores the communication connection with the information server based on the stored connection information.
