Method for processing an incoming call in a telecommunications network and TAS server implementing same

A Telephony Application Server (TAS) server configured to handle an incoming call intended for a called terminal in an Internet Protocol Multimedia Subsystem (IMS) network, said server including:

• a processor:
• and
• a non-transitory computer-readable medium comprising instructions stored thereon, which when executed by the processor configure the TAS server to:
• interrogate a Service Data Management (SDM) entity to determine whether a service profile associated with said called terminal has Terminating Intelligent Network (IN) service marks;
• interrogate an SDM entity to determine whether a routing domain to be used to route the call towards the called terminal is of a circuit or packet type;
• and
• route the call towards said terminal;
• determine, in response to said routing domain being of packet type, whether said called terminal is actually reachable in packet mode, and if so, via which type of access network;
• differentiate a Terminating IN service configured, in the case where said service profile has Terminating IN service marks, to allow differentiating the Terminating IN service provided to the called terminal depending on the type of access network of the called terminal.

A non-transitory computer-readable recording medium on which a computer program is recorded comprising instructions for executing a method for handling an incoming call intended for a called terminal in a telecommunications network, when the instructions are executed by a processor of a Telephony Application Server (TAS) server in an Internet Protocol Multimedia Subsystem (IMS) network, wherein the instructions configure the TAS server to:

• interrogate a Service Data Management (SDM) entity to determine whether a service profile associated with said called terminal has Terminating Intelligent Network (IN) service marks;
• interrogate an SDM entity to determine whether a routing domain to be used to route the call towards the called terminal is of a circuit or packet type;
• and
• route the call towards said called terminal;
• in response to said routing domain being of the packet type, determine whether said called terminal is actually reachable in packet mode, and if so, via which type of access network;
• and
• in response to the service profile having Terminating IN marks, differentiate the Terminating IN service provided to said called terminal depending on the type of access network of the called terminal.
