Abstract

In a case where a communication control apparatus incorporated by a portable device detects a communication request from an external device and decides whether to perform communications, it is hard to determine, with a high degree of precision, whether the owner of the portable device incorporating the communication control apparatus has an intention to use the portable device in response to the communication request. In order to solve this problem, there are included a distance measuring means for measuring spatial distances from any given objects that have distances of a particular range in a direction of a particular range and that are adjacent to each other; a condition storing means for storing predetermined distance conditions; and a communication means that becomes, based on a result of comparison of the values of the spatial distances with the distance conditions, communicatable in response to the externally received communication request.
