20130310027 | Method and Apparatus for Associating Service Provider Network Identifiers with Access Network Identifiers - According to one aspect of the teachings herein, a token is logically bound to an external identifier and provided to a wireless device via triggering signaling sent to the wireless device through an access network. The wireless device is configured to send registration signaling through the access network to a service provider network, in response to the triggering signaling and to return the token in such signaling. With this advantageous approach, the service provider network recognizes the token returned from the wireless device and thereby learns the association between a service provider network identifier that is received in the registration signaling for identifying the wireless device with respect to a service provided by the service provider network, and an external identifier assigned by the access network for use by the service provider network in identifying the wireless device to the access network. | 11-21-2013 |

The service provider network identifiers are used to identify those same wireless devices within the service provider network, with respect to one or more services. The binding thus enables the service provider network to trigger communications with a targeted wireless device via the access network, by using the external identifier that is bound to the service provider network identifier of the targeted device, and sending trigger signaling to the access network that identifies the targeted wireless device via the external identifier. | 11-28-2013 |
20130318218 | Method and Apparatus for Associating Service Provider Network Identifiers with Access Network Identifiers - 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. | 11-28-2013 |
