An access network sends allocation information to an external service provider network (SPN), responsive to a wireless device establishing a data session with the access network for communicating with the SPN. The allocation information indicates the Internet Protocol (IP) address assigned to the wireless device by the access network for the data session and an external identifier to be used by the SPN in identifying the wireless device to the access network. Subsequently, the SPN receives a service provider network identifier and point of contact information in signaling sent from the wireless device, and binds the service provider network identifier to the external identifier that is associated with the IP address indicated in the point of contact information. This binding enables the SPN to trigger communications targeting the service provider network identifier of the wireless device, by sending triggering signaling to the access network that includes the bound external identifier. |
