Abstract: In a communication apparatus, a communication processor rebuilds, with switching of communication systems, a communication bearer to perform communication. An application processor outputs, when background communication occurs or a display unit is shifted from an off state to an on state while notification from the communication processor is stopped, a request signal to the communication processor. The application processor starts the background communication based on information of a latest communication bearer output from the communication processor in response to the request signal.

Abstract: A mobile apparatus, that has a calling function, includes: a location-information acquisition unit to acquire location information indicative of a location of the mobile apparatus, and a location-information notification unit to send the location information to a receiving-side apparatus when a call is made to the receiving-side apparatus, the location-information notification unit being further operable to provide, when the call is being made to a receiving-side apparatus, the location information in a manner such that, before a communication connection is established therewith, the receiving-side apparatus can recognize a physical location where the call is being originated based upon the location data.

Abstract: A communication apparatus which communicates with an external apparatus by receiving a communication request transmitted from the external apparatus based a call-out number uniquely allocated to the communication apparatus, includes: a communication request receiver which receives identification information allocated to the external apparatus and the communication request independently of a call-out number of the external apparatus; a display which displays information; an information storage which stores an association table associating the identification information of the external apparatus with apparatus information used for displaying in reception of the communication request from the external apparatus; and a display controller which, when the communication request receiver receives a communication request with identification information, displays apparatus information recorded in the association table stored in the information storage on the display, which is associated with identification information
