Abstract

A mobile terminal device determines whether it is located in the local radio area of the network or in another radio area and the determined radio area is indicated to an application of the network. The application is used to control a communication request addressed to the mobile terminal device. Communication requests coming in on the network can be directly switched to the local radio area using the application or can be directly forwarded to the mobile radio address in the mobile radio network of which the mobile terminal device is located, thereby avoiding or substantially reducing roaming or forwarding of communication requests from the local radio area to another radio area and thereby achieving an economical operation of mobile telephone terminal devices with local radio area.

Claims20

Dependent claims

A method for switching communication links to a mobile terminal device that is allocated to a local radio area network, the mobile terminal device having a first address for communications when in a first local radio area of the local radio area network, the method comprising:

a first mobile terminal device determining whether the mobile terminal device is in the first local radio area to which the first mobile terminal device is allocated or in another radio area that is not within the first local radio area;
the first mobile terminal device signaling to an application of the network the determined radio area of the first mobile terminal device, the signaling of the determined radio area by the first mobile terminal device being effected by the first mobile terminal device sending a message to an application of the network, the message being one of:
(i) a Register Request Message containing a parameter indicating that the first mobile terminal device is located in a second radio area, the parameter comprising a second address of the mobile communication device, and
(ii) a Register Request Message containing a parameter indicating that the first mobile terminal device is not located in the first local radio area;
via the application of the network, controlling directly on the first local radio area of the network a communication request addressed by another network to the first mobile terminal device when the first mobile terminal device is determined to be in the first local radio area;
and
when the first mobile terminal device is not in the first local radio area of the network, performing one of:
forwarding the communication request addressed by the other network to the first mobile terminal device via the application of the network directly with an address of the determined radio area of the first mobile terminal device,
forwarding the communication request addressed by the other network to the first mobile terminal device via the application of the network directly to the determined radio area of the first mobile terminal device, and
informing the other network that addressed the communication request that the first mobile terminal device is not in the first local radio area;
and
wherein the second address is a phone number for contacting the first mobile terminal device when the first mobile terminal device is in the second radio area and is no longer in the first local radio area.

9 more elements

A method for transmitting information relating to communication links for a mobile terminal device assigned to a first local radio area of a network, the mobile terminal device having a first address for communications when in the first local radio area, the method comprising:

the mobile terminal device determining that the mobile terminal device is located in a second radio area and is no longer in the first local radio area, the determination made by the mobile terminal device being based upon a comparison of a recognition signal to be received by the mobile terminal device when the mobile terminal device is in the first local radio area of the network with a recognition signal received when the mobile terminal device is located in the second radio area;
signaling the determined second radio area by the mobile terminal device to an application on the network, the signaling comprising the mobile terminal device transmitting an indication that the mobile terminal device is no longer in the first radio area to the application via a network-specific terminal device protocol, wherein the signaling of the determined second radio area by the mobile terminal device is effected by the mobile terminal device sending a message to the application of the network, the message being one of:
(i) a Register Request Message containing a parameter indicating that the mobile terminal device is located in the second radio area, the parameter comprising a second address of the mobile communication device, and
(ii) a Register Request Message containing a parameter indicating that the mobile terminal device is not located in the first local radio area;
and
through the application, directing a communication request addressed to the mobile terminal device to the mobile terminal device for communications with the mobile terminal device by use of a second address when the mobile terminal device is in the second radio area wherein the second address is a phone number for contacting the mobile terminal device when the mobile terminal device is in the second radio area and is no longer in the first local radio area.

3 more elements

A communication request system comprising:

a first application in a mobile terminal device for identifying the mobile terminal device's location in a first local radio area of a first network to which the mobile terminal device is assigned or a second radio area, the mobile terminal device having a first address for being reached when located in the first local radio area and a second address that is different than the first address for communications when in the second radio area, wherein the second address is a phone number for contacting the mobile terminal device when the mobile terminal device is in the second radio area and is no longer in the first local radio area of the first network;
upon a determination that the mobile terminal device is in the second radio area based upon a comparison of a recognition signal to be received by the mobile terminal device when the mobile terminal device is in the first local radio area with a recognition signal received by the mobile terminal device when the mobile terminal device is in the second radio area, the mobile terminal device signaling the identified second radio area to a second application on the first network, the signaling comprising the mobile terminal transmitting an indication that the mobile terminal device is no longer in the first radio area to the second application via a network-specific terminal device protocol,
wherein the signaling is effected by one of:
(i) a Register Request Message containing a parameter indicating that the mobile terminal device is located in the second radio area, the parameter comprising the second address of the mobile communication device, and
(ii) a Register Request Message containing a parameter indicating that the mobile terminal device is no longer located in the first local radio area.
