Selection of M2M devices by external triggering
First Claim
1. A method, in one or more nodes of a wireless communications network serving a wireless device, of supporting triggering of the wireless device by a service provider external to the wireless communications network, the method comprising:
- receiving a trigger message from the service provider, the trigger message including an external identifier for the wireless device;
identifying an internal network identifier for the wireless device and an associated data network identifier, based on the external identifier; and
forwarding the internal network identifier and the data network identifier towards the wireless device, for use by the wireless device in activating or selecting a data session.

Abstract
Techniques for facilitating the activation or establishing of a data session between an M2M device and a service provider external to the wireless communications network serving the M2M device are disclosed. In an example method, a trigger message is received from the service provider, the trigger message including an external identifier for the wireless device. An internal network identifier for the wireless device and an associated data network identifier are identified, based on the external identifier. The internal network identifier and the data network identifier are then forwarded towards the wireless device, for use by the wireless device in activating or selecting a data session. The data network identifier may include an APN, or an NSAPI, or both, in some embodiments. The disclosed techniques are particularly useful in the context of wireless devices having subscriptions to more than one M2M service provider.

11. A home subscriber server node for use in a wireless communications network serving a wireless device, the home subscriber server node comprising:
-
one or more interfaces adapted for communication with at least a radio access network serving the wireless device and one or more other nodes in the wireless communication network, and one or more processing circuits adapted to; maintain a binding between an external identifier for the wireless device, an internal identifier for the wireless device, and a data network identifier corresponding to the external identifier; receive a query from a second node in the radio access network, the query comprising the external identifier for the wireless device; and retrieve the internal network identifier and an associated data network identifier, in response to the query and based on the maintained binding, wherein the associated data network identifier includes an Access Point Name (APN) or a Network Service Access Point Identifier (NSAPI), or both; and send the internal network identifier and the associated data network identifier to the second node. - View Dependent Claims (12, 13)
