Abstract

A method and devices for dialling services in a mobile telecommunication network include a set of stored character strings used for comparison with character strings entered by a subscriber to call a service is modified, if a mobile user equipment switches from or to a visited telecommunication network.

Claims

1. A node for a telecommunication network, comprising:

a receiving unit for receiving a service identifier;

a memory for storing a dialing number;

a processing unit for mapping the service identifier into a dialing number allocated to the service identifier;

means for setting up a call to the service allocated to the dialing number; and

means for updating a set of character strings used for dialing services and stored in a mobile user equipment.

2. The node according to claim 1, comprising:

means for recognizing a language indicator; and

means for allocating dialing numbers to the language indicator.

3. The node according to claim 1, comprising:

means for determining a country code of a home telecommunication network of the mobile user equipment; and

means for allocating dialing numbers to a country code.

4. The node according to claim 1 wherein the means for updating a set of character strings used for dialing services and stored in a mobile user equipment includes:

means for detecting a new mobile user equipment;

a storage means storing character strings used for dialing services in the network; and

means for transmitting the character strings allocated to service identifiers to the mobile user equipment.

5. A method of controlling a call for dialing a service from a mobile user equipment to a node within a mobile telecommunication network, the method comprising the steps of:

receiving a service identifier, by the node, from the mobile user equipment;

storing a dialing number in the node;

mapping the service identifier into a dialing number allocated to the service identifier;

setting up a call, by the node, to the service allocated to the dialing number; and

updating, by the node, a set of character strings used for dialing services and stored in the mobile user equipment.

6. The method of controlling a call of claim 5 further comprising the steps of:

recognizing a language indicator; and

allowing dialing numbers to the language indicator.

7. The method of controlling a call of claim 5, further comprising the steps of:

determining a country code of a home telecommunication network of the mobile user equipment; and

allocating dialing numbers to a country code.

8. The method of controlling a call of claim 5 wherein the step of updating, by the node, a set of character strings used for dialing services and stored in the mobile user equipment includes the steps of:

detecting a new mobile user equipment;

storing character strings used for dialing services in the network; and

transmitting the character strings allocated to service identifiers to the mobile user equipment.
