An application server generates a script and transmits the script to a first user equipment. The script is transmitted to the first user equipment in a request for establishment of a communication session between the first user equipment and a second user equipment. Execution of the script by the first user equipment controls handling of the communication session between the first user equipment and the second user equipment. Thus, by sending the script to the first user equipment, the application server controls the manner in which the first user equipment handles the communication session.

There are provided mechanisms for registering and subsequently communicating with classified subscribers in an IMS environment. The method comprises replacing an IMS Public -and Private User identity (IMPU/IMPI) with randomized temporary identifiers. Parties, in particular parties with 5 access to network entities outside the home-network cannot relate the observed IMPU/IMPI to the subscriber's original IMPU/IMPI as provisioned, and as the temporary IMPU changes frequently, there is no pattern (registration nor call) to be allocated to the subscriber's UE.

Protecting user's anonymity when visiting foreign networks

Method, device, network and network entity for providing at least one Internet Protocol, IP, service application from a subscriber's multimedia device in an IP multimedia network. The method comprises executing at least one IP service application on the device and/or on an auxiliary device associated with the device. A Domain Name System, DNS, service is provided being executed on the device the DNS service relating to a domain associated with the subscriber. The DNS service has a memory associated therewith. In the memory information is stored relating to DNS resource records in accordance with the at least one IP service application that is being executed on the device and/or in the auxiliary device at that moment. An indication of the device's capability to execute a DNS service is deposited with the IP multimedia network. The indication comprises a network address on which the DNS service can be reached for a DNS query.

A method system and device are described as a solution for a called party that receives a call from a calling party that intends to be another calling party by means of A-number spoofing. The method comprises a verification request by the called party network during a call setup, made to the network of the assumed calling party. The address of the network of the assumed calling party is derived from the Calling Party Number CgPN identifier or Calling Line Identification CLI as provided by a call setup. When the CgPN is correctly provided, a verification request with the network where the calling party resides will yield status information that the calling party indeed has a call setup with the called party. When the A-number is spoofed, the verification will not yield status information that the calling party has a call setup with the called party.
