Abstract:
1. A method for notifying a wireless client device of termination of at least one service provided to the client device by a server system through a wireless network, the server system being disposed within an enterprise network having access to the wireless network, the method comprising the steps of: during a provisioning operation carried out between the server system and the client device over a secure private channel, establishing authentication data and notification data, sending the authentication data to the client device for storage in non-volatile memory within the client device, and storing the notification data at the server system, wherein the notification data is related to the authentication data; establishing said service provided to said client device by said server system; detecting, at the server system, a breakdown in said service by receiving an encrypted packet from the client device, attempting decryption of the encrypted packet at said server system, and determining that said decryption failed; and based on detecting said breakdown, transmitting said notification data to said client device, wherein said client device may authenticate said notification data received from the server system on the basis of the stored authentication data and the relationship between the notification data and the authentication data, and wherein said provisioning operation includes establishing an encryption process for communications between the client device and the server system, and wherein the service is carried out at least substantially through encrypted communications.
