Abstract
To provide a portable terminal that can establish an ad hoc network by operating existing communication unit without requiring a burdensome operation of manually exchanging ad hoc setting information. The distribution determination section of a receiving portable terminal compares a message digest that is calculated by a telephone calling application from a received telephone number and one received by the short-distance wireless communication section. If the values of the message digests match, the distribution determination section informs the user that the calling portable terminal is capable of ad hoc communication such as on a liquid crystal display. When an operation assigned to start of ad hoc communication is performed on the receiving portable terminal, the distribution determination section sends ad hoc communication settings information to the short-distance wireless communication section to set the short-distance wireless communication section to ad hoc mode, and transmits the ad hoc communication setting information to the calling portable terminal utilizing communication unit of the telephone calling application.
