摘要
The invention relates to a method for processing an incoming call to a called terminal in a telecommunications network, said method being implemented by a TAS server in an IMS network. Said method comprises: a step (E10) of interrogating an SDM entity in order to determine whether the service profile of the user associated with the called terminal contains IR terminating service information; a step (E20) of interrogating an SDM entity in order to determine whether the routing domain to be used to route the call to the called terminal is a circuit or packet type; if said routing domain is a packet type, a step (E30) of determining whether said called terminal is effectively reachable in packet mode, and if applicable, via which type of access network; if the service profile of said user contains IR terminating information, a step (E40) allowing the IR terminating service provided for said user of the called terminal to be distinguished according to the type of access network of the called terminal; and a step (E50) of routing the call to said called terminal.
