Claim Text:
1. A method at a network node associated with a service provider network that is external to an access network, said method comprising: receiving an external identifier that has been assigned by an access network for externally identifying a wireless device that also has a predefined service provider network identifier for using a service provided by the service provider network; triggering the wireless device to establish a data session with the access network for use in registering for the service with the service provider network, based on sending triggering signaling toward the access network that identifies the wireless device via the external identifier and includes a token for forwarding to the wireless device; receiving registration signaling sent from the wireless device via the access network, said registration signaling sent responsive to the triggering signaling sent from the service provider network; and responsive to recognizing that the registration signaling includes the forwarded token, binding the external identifier of the wireless device to the service provider network identifier of the wireless device, to thereby establish a mapping between the external identifier and the service provider network identifier, for subsequent use by the service provider network in triggering communications with the wireless device through the access network.
