Mobile communication terminal and method therefore
View Patent ↗Control of setup of international calls in a mobile communication terminal is performed. The terminal is connected to a first mobile communication network that is operated by a first operator, and the method includes detecting a request to setup an international call, the request including a first symbol sequence including a country code and a subscriber identifier, selecting, in response to the detection, an operator prefix number, the operator prefix number specifying a second operator of a communication network that provides an international call setup service, creating a second symbol sequence including the operator prefix number, the country code and the subscriber identifier, and requesting a call setup with the subscriber via the second operator, the request including transmitting the second symbol sequence to the first mobile communication network.
1. A method comprising in a mobile communication terminal:
detecting a request for the mobile communication terminal to setup an international call from a home country of the mobile communication terminal to another country, the request comprising a first symbol sequence including a country code of said other country and a subscriber identifier,
in response to the detection, automatically selecting an operator of a communication network that provides an international call setup service from a plurality of operators by selecting an operator prefix number for the selected operator, wherein the operator of the international call setup service and associated operator prefix number are selected on the basis of the detected country code to which the international call is requested to be set up,
creating a second symbol sequence comprising the selected operator prefix number, the country code and the subscriber identifier, and
requesting a call setup with said subscriber via said the selected operator, the request comprising causing transmission of the second symbol sequence to a first mobile communication network.
2. The method according to claim 1 , wherein said selection of an operator prefix number involves selection from a list comprising the plurality of operators.
3. The method according to claim 2 , wherein said list comprises at least two operators of a respective communication network associated with a respective country code.
4. The method according to claim 1 , further comprising:
receiving, prior to detecting a request to setup an international call, at least one operator prefix number for use in creating said second symbol sequence.
5. The method according to claim 4 , wherein said reception of the at least one operator prefix number involves reception of user input via a user interface in a terminal.
6. The method according to claim 4 , wherein said reception of the at least one operator prefix number involves reception via any of:
keypad input,
a wireless data interface, and
a wired data interface.
7. The method according to claim 4 , wherein said reception of the at least one operator prefix number involves reception via said first mobile communication network.
8. The method according to claim 7 , wherein the reception via said first mobile communication network involves reception from an operator of the first mobile communication network.
9. An apparatus comprising a processor and a memory storing computer-readable instructions, wherein the memory and stored computer-readable instructions are configured, with the processor, to cause the apparatus to at least:
detect a request for the apparatus to setup an international call from a home country of the apparatus to another country, the request comprising a first symbol sequence including a country code of said other country and a subscriber identifier,
automatically select, in response to the detection, an operator of a communication network that provides an international call setup service from a plurality of operators by selecting an operator prefix number for the selected operator,
wherein the operator of the international call setup service and associated operator prefix number are selected on the basis of the detected country code to which the international call is requested to be set up,
create a second symbol sequence comprising the selected operator prefix number, the country code and the subscriber identifier, and
request a call setup with said subscriber via said the selected operator, the request comprising causing transmission of the second symbol sequence to the first mobile communication network.
10. A non-transitory computer readable medium storing computer readable software instructions that, when executed in a computing apparatus, performs a method comprising:
detecting a request for a mobile communication terminal to setup an international call from a home country of the mobile communication terminal to another country, the request comprising a first symbol sequence including a country code of said other country and a subscriber identifier,
in response to the detection, automatically selecting an operator of a communication network that provides an international call setup service from a plurality of operators by selecting an operator prefix number for the selected operator, wherein the operator of the international call setup service and associated operator prefix number are selected on the basis of the detected country code to which the international call is requested to be set up,
creating a second symbol sequence comprising the selected operator prefix number, the country code and the subscriber identifier, and
requesting a call setup with said subscriber via said the selected operator, the request comprising causing transmission of the second symbol sequence to a first mobile communication network.
