First Claim
1. A method for routing a service request in a telecommunication system towards a destination user, the method comprising the steps of:
- a) storing a collection of identifiers related to a first identifier assigned to said user;
b) receiving a service request that comprises said first identifier;
c) obtaining a plurality of identifiers among said collection of identifiers;
d) selecting a second identifier among said plurality of identifiers; and
e) routing said service request according to said selected second identifier;
wherein at least one identifier among said plurality of identifiers stored in step a) has a format that comprises a user-name portion and a domain-name portion, wherein the user-name portion contains said first identifier; and
in step d) said second identifier is selected having a format comprising a user-name portion and a domain-name portion, wherein said user-name portion contains said first identifier.

Abstract
A method for routing a service request in a telecommunication system in cases where the identifier received for the destination of the service is not (or can not be) suitable for routing the service, such as when a E.164 number is received in IP based multimedia telecommunication systems. Upon reception of a service request in a telecommunications node of the telecommunication system in charge of serving control for services, a query comprising the received identifier is made to a translation database. As a result, a plurality of identifiers related to the received identifier are received that can have different formats and imply different service types. The service is further routed from said telecommunications node according to an identifier selected among said plurality of identifiers that contains the primarily received identifier in the user name portion.

6. A system for routing a service request in a telecommunication system, the system comprising:
-
a data base, in charge of storing a collection of identifiers related to a first identifier associated to a user; and
a serving node of said telecommunication system in charge of receiving a service request towards a destination user and further routing said service request;
said data base being arranged to receive a query comprising the content of said first identifier, and to answer said query with a plurality of identifiers among said collection of identifiers;
said serving node being arranged for querying said data base upon reception of a service request that comprises said first identifier, and further routing said service request according to an identifier selected among said plurality of identifiers;
wherein said serving node is further arranged for routing service request according to an identifier selected among said plurality of identifiers that has a format comprising a user-name portion and a domain-name portion, wherein said user-name portion contains said first identifier. - View Dependent Claims (7, 8)
