Abstract:
A device determines a connection status of a Public Land Mobile Network (PLMN) communication interface and a wireless Local Area Network (LAN) communication interface, and stores the connection status in a queue. The device waits, subsequent to storing the connection status, for expiration of a time delay; and retrieves, subsequent to the expiration of the time delay, the connection status or another connection status from the queue. The device sends, based on the retrieved connection status or the other connection status, a service validation request to a server associated with the PLMN, and receives from the server, in response to the service validation request, a validation response that authorizes service delivery to the device via a PLMN.
