Method and apparatus for delivering keys

摘要

The present invention encompasses an electronic device, such as a server, which may be operated in a communication system. The electronic device comprises a method for receiving a request from another electronic device to transmit keys, for example a mobile terminal. Responsive to the request, the server generates the required keys and determines a best time to send the keys to the mobile client device such that a new connection is not required just for sending the requested keys. The best time to send the keys may be during a scheduled connection for sending non-key data, for example a connection setup for transmitting system parameters, content data, etc. By sending the keys along with the non-key data, a need for a special connection is avoided.

scheduling at a core network, a time to open a scheduled connection with a client device for transmitting non-key data to the client device; determining in the client device whether to request said one or more keys for decrypting content previously stored in the client device; requesting delivery of said one or more keys from the core network; and receiving in the client device said one or more keys attached to a non-key data message from the core network during the scheduled connection for transmitting the non-key data.
