Broad band transmission path modem, radio terminal device, program, and recording medium

A radio terminal device comprising:

• a first interfacing section that interfaces with a mobile communication network;
• a second interfacing section that interfaces with a radio access link other than said mobile communication network;
• and
• a controller that sets up one call which occurs in a local station and whose communication channel is formed via said radio access link, and sets up another call whose communication channel is formed via said mobile communication network or said radio access link, and maintains, when both of the calls persist as completed calls, a speech relating to one of the completed calls specified by an operator and holds the communication channel of the other completed call.

A radio terminal device comprising:

• a first interfacing section which interfaces with a mobile communication network;
• a second interfacing section used for accessing a radio access link other than said mobile communication network, when detecting a state that the access is possible;
• and
• a controller that sets up one call which occurs in a local station and whose communication channel is formed via said radio access link, and sets up another call whose communication channel is formed via said mobile communication network or said radio access link, wherein
• when detecting the state, said second interfacing section delivers, to said radio access link, a number assigned in advance to a local station and conforming to a numbering plan of a network accessible via said radio access link.

A radio terminal device comprising:

• a first interfacing section that interfaces with a mobile communication network;
• a second interfacing section used for accessing a radio access link other than said mobile communication network, when detecting a state that the access is possible;
• a profile storage section in which a number given to a terminal is registered, the terminal is to be a transfer destination of a terminating call that is to arrive at a local station;
• and
• a controller that sets up one call which occurs in a local station and whose communication channel is formed via said radio access link, and sets up another call whose communication channel is formed via said mobile communication network or said radio access link, wherein
• when detecting the state, said second interfacing section delivers the number registered in said profile storage section to said radio access link.

A radio terminal device comprising:

• a first interfacing section that interfaces with a mobile communication network;
• a second interfacing section used for accessing a radio access link other than said mobile communication network, when detecting a state that the access is possible;
• a number storage section in which a plurality of numbers given to individual opposite parties are registered, the opposite parties being to be terminating parties of an originating call from a local station;
• and
• a controller that sets up one call which occurs in a local station and whose communication channel is formed via said radio access link, and sets up another call whose communication channel is formed via said mobile communication network or said radio access link, wherein
• when detecting the state, said second interfacing section delivers all of the numbers registered in said number storage section to said radio access link.

• and
• a controller that sets up one call which occurs in a local station and whose communication channel is formed via said radio access link, and sets up another call whose communication channel is formed via said mobile communication network or said radio access link, and that re-originates, when it is determined that one of the calls as an originating call is incomplete, a call by using a number registered in said number storage section and given to an opposite party as a terminating party of the originating call.
