Communication device, communication method, and computer program product

A communication method comprising:

• detecting a call instruction from a user as call instruction information;
• searching that includes searching for a base station that is connectible, and collecting base station information related to the base station that is connectible;
• storing the base station information;
• sending connection request information, which indicates a connection request with respect to the base station, and call request information, which indicates a call request;
• receiving a response from the base station;
• and
• communication-controlling that includes controlling connection with the base station, wherein
• the communication-controlling includes
• sending, according to the call instruction information, the call request information to a first-type base station representing an already-connected base station, and
• when a response from the first-type base station is not receivable, identifying base station information of a second-type base station, which is different than the first-type base station, from stored base station information and sending the connection request information.

A computer program product having a computer readable medium including a communication program, wherein the communication program, when executed by a computer, causes the computer to execute:

• a detecting function for detecting a call instruction from a user as call instruction information;
• a searching function for searching for a base station that is connectible, and collects base station information related to the base station that is connectible;
• a storing function for storing the base station information;
• a sending function for sending connection request information, which indicates a connection request with respect to the base station, and call request information, which indicates a call request;
• a receiving function for receiving a response from the base station;
• and
• a communication control function for controlling connection with the base station, wherein
• the communication control function
• sends, according to the call instruction information, the call request information to a first-type base station representing an already-connected base station, and
• when a response from the first-type base station is not receivable, identifies base station information of a second-type base station, which is different than the first-type base station, from stored base station information and sends the connection request information.
