Abstract
The present invention is directed to a method of providing a service through a user equipment (UE) unit in an internet protocol (IP) multimedia subsystem (IMS) telecommunications network, wherein said service is provided using an application server (AS) in said telecommunications network, said method comprising a step of performing a user authorisation query on a user database server for authorizing registration of said user equipment unit in said telecommunications network, and wherein said method further comprises a step of performing a service authorisation query on a service policy server for authorizing use of said service through said user equipment unit. The invention further relates to a user database server, a service policy server, an application server, and an interrogating call session control function (I-CSCF) entity for use in the method described above.
