Abstract

A portable electronic key for use with an electronic locking device comprises a wireless communications module, a processor, and a software application configured to transmit, receive, and respond to electronic messages related to access control information. The electronic messages are formatted according to a request-response protocol. The wireless communications module is configured to use a standardized communication protocol to establish a wireless communications link with a networking device operably associated with a remote administration device located away from the portable electronic key. The software application periodically exchanges, via the wireless communications link, request-response messages related to access control information with a server application of the remote administration device. The processor responds to the exchange of request-response messages by performing at least one of modifying access control information of the portable electronic key or providing access control information of the portable electronic key to the remote administration device.

maintaining in memory sites of the portable electronic key the access credential including a first schedule defining, for each member of the set of electronic locking devices, a corresponding period in which the portable electronic key is authorized to initiate the access event;

establishing, based on a wireless networking standardized communication protocol, a wireless communications link between the portable electronic key and a networking device operatively associated with a remote administration device located away from the portable electronic key;

transmitting from the portable electronic key, through the wireless communications link, a first message formatted according to a request-response protocol and including an instruction for exchanging access control information between a first application of the portable electronic key and a second application of the remote administration device located away from the portable electronic key;

receiving, at the portable electronic key and in response to the message, the access control information that causes a change from the first schedule to a second schedule, the second schedule being different from the first schedule; and

in response to receiving the access control information, accessing the memory sites for configuring the access credential in accordance with the second schedule and thereafter transmitting, through the wireless communications link to the second application of the remote administration device, a second message formatted according to a request-response protocol, the second message representing the updated access credential, to thereby facilitate, at the remote administration device located away from the portable electronic key, administration of the access control system by exchanging messages with the portable electronic key to enable the portable electronic key to initiate the access event at any member of the set of electronic locking devices according to the second schedule and to further enable remote monitoring of the access credential maintained in memory sites of the electronic key.

2. The method of claim 1, wherein the wireless networking standardized communication protocol is selected from the group consisting of a Bluetooth protocol, an IEEE 802.11 (Wi-Fi) protocol, an IEEE 802.16 (WiMax) protocol, an IEEE 802.15.4 (ZigBee) protocol, a 3rd Generation Partnership Project (3GPP) protocol, a Long Term Evolution (LTE) protocol, a Global System for Mobile Communications (GSM) protocol, and a Code Division Multiple Access (CDMA) protocol.

3. The method of claim 1, wherein the wireless communications link is established over a network selected from the group consisting of a wireless local area network, a wireless personal area network, a wireless mesh network, a wireless wide area network, a wireless ad hoc network, a cellular network, and Internet.

4. The method of claim 1, wherein the first message and the second message are formatted according to a layer 7 application protocol in accordance with an Open System Interconnection (OSI) model.

5. The method of claim 1, wherein the first message and the second message are formatted according to a protocol selected from the group consisting of a hypertext transfer protocol (HTTP), a hypertext transfer protocol secure (HTTPS), a file transfer protocol (FTP), and a secure file transfer protocol (SFTP).

6. The method of claim 1, wherein the first application is a credential management application, and wherein the credential management application is further configured to operate in a client-server relationship with the second application.

7. The method of claim 6, wherein the second application is a server application, and wherein the server application is selected from the group consisting of a web server, a database server, an application server, and a file server.

8. The method of claim 1, wherein the first schedule defines for a first member of the set of electronic locking devices, a first period in which the portable electronic key is authorized to initiate the access event, and further defines for a second member of the set of electronic locking devices, a second period in which the portable electronic key is authorized to initiate the access event, the second period being different than the first period.

9. An access control system for remote administration of access control information, the system comprising:
