Abstract
A method and apparatus are described for processing service layer detach commands and attach notifications. A services capability server (SCS) may request a core network to perform a network initiated detach of a device. This procedure may be used when the SCS knows that the device will not be needed for a long time or when the SCS detects some event that may warrant a detach, (e.g., theft, disallowed location, integrity validation failure). The SCS may be asked if the device may be allowed to attach at this time. If the SCS indicates that the attach may be rejected, the device may not be allowed to attach until a later time, thus avoiding additional activity on control and user planes. The SCS may be informed when a device is attached based on various subscription fields stored in a home subscriber server (HSS).
