Abstract
A method of handling SIP session initiation requests in an IP Multimedia Subsystem, IMS, network. The method is performed at an application server, AS, within the network. The AS receives a session initiation request containing a destination address, where that destination address is currently associated with a plurality of registered User Equipments, UEs. The AS then determines whether or not a UE associated with the destination address, is already involved in a session. If so, the AS causes the session initiation request to be forwarded only to that UE. If not, the AS causes the session initiation request to be forwarded to all UEs registered in respect of the address.
