Mobile communication terminal and call handover method
First Claim
1. A mobile communication terminal comprising:
- a radio communication unit configured to perform radio communications;
a user information storage unit configured to store user information in which a terminal identifier for identifying an arbitrary communication terminal, and a user identifier for identifying a user of the arbitrary communication terminal are associated with each other;
an identifier storage unit configured to store, when performing a call with a communication terminal of the other party of the call via the radio communication unit, a first identifier for identifying the communication terminal of the other party of the call;
a terminal identifier determination unit configured to determine whether the first terminal identifier stored in the identifier storage unit and a second terminal identifier included in a call-out signal are associated with the same user identifier, with reference to the user information stored in the user information storage unit, in a case where the radio communication unit receives the call-out signal including the second terminal identifier during the call with the communication terminal of the other party via the radio communication unit; and
a call controller configured to control the radio communication unit to hand over the call to a communication terminal indicated by the second terminal identifier in a case where the terminal identifier determination unit determines that the first terminal identifier stored in the identifier storage unit and the second terminal identifier included in the call-out signal are associated with the same user identifier.

Abstract
Disclosed is a mobile communication terminal including: a user information storage unit for storing user information having a terminal identifier for identifying an arbitrary communication terminal, and a user identifier for identifying the user of the communication terminal associated with each other; an identifier storage unit for storing, at the time of beginning of a call with the other party of the call, a first identifier for identifying the communication terminal of the other party of the call; a terminal identifier determination unit for determining whether the first terminal identifier and a second terminal identifier are associated with the same user identifier, with reference to the user information, upon receipt of a call-out signal including the second terminal identifier during the call with the communication terminal of the other party; and a call controller for handing over the call to a communication terminal indicated by the second terminal identifier when the terminal identifier determination unit determines that the first and second terminal identifiers are associated with the same user identifier.
