Abstract
There is provided a method of ensuring that an identifier for a subscriber of an IP Connectivity Access Network (IP-CAN) is available to a third-party service provider that can provide a service to the subscriber. The method comprises, at an application server of the third-party service provider, receiving a service request message from the subscriber, the service request message requesting access to the service, obtaining a source IP address and source port number from the service request message, generating an identity request message including the source IP address and source port number, the identity request message requesting a subscriber identifier associated with the source IP address and source port number, sending the identity request message to a node of the IP-CAN, and receiving an identity response message from the node of the IP-CAN, the response including a subscriber identifier that the IP-CAN associates with the subscriber.
