context: 8.7.1 Test Purpose (TP) (1) with { UE being registered to IMS } ensure that { when { UE is made to activate CFU } then { UE authenticates itself using GBA or Digest } } (2) with { UE having started authentication } ensure that { when { UE receives 200 OK concluding the authentication } then { UE sends HTTP request to activate CFU } } (3) with { UE having concluded activation of CFU } ensure that { when { UE is made to de-activate CFU } then { UE sends HTTP request to de-activate CFU } } 8.7.2 Conformance Requirements The conformance requirements covered in the present test case are, unless otherwise stated, Rel-15 requirements. [TS 24.604, clause 4.2.1.2]: The CFU service enables a served user to have the network redirect to another user communications which are addressed to the served user's address. The CFU service may operate on all communication, or just those associated with specified services. The served user's ability to originate communications is unaffected by the CFU
description: Communication Forwarding Unconditional (CFU) is a telecommunications service that enables a served user to have the network redirect communications addressed to their address to another user. The CFU service may operate on all communication or just those associated with specified services, and it does not affect the served user's ability to originate communications.
explanation: The context describes CFU as a service that allows for the redirection of communications, which aligns with the definition of a telecommunications service. The details about its operation, such as redirecting communications addressed to a served user's address and the option to operate on all communication or specified services, further support this classification.
