Abstract

A method and system is disclosed for providing intelligent remote access to wireless transmit/receive units (WTRUs). A translator is provided in base stations so that system controllers may issue application level network management protocol messages to base stations. The messages are transmitted by the translator to a medium access control (MAC) messaging protocol and forwarded to WTRUs. Information provided by WTRUs to base stations is translated from a MAC protocol to an application level network management protocol so that the information may be accessed by system controllers using application level network management protocols.

Claims

1. A method for communicating information between network entities in a wireless communication system comprising at least one base station, at least one system controller, and at least one wireless transmit/receive unit (WTRU), the method comprising:

communicating network management information for a system controller and WTRU between the system controller and a base station using an application level network management protocol; and

,

communicating said network management information between the base station and the WTRU using a MAC messaging protocol.

2. The method of claim 1 wherein the base station translates between the application level network management protocol and the MAC messaging protocol.

3. The method of claim 2 wherein the application level network management protocol is simple network management protocol (SNMP).

4. The method of claim 3 wherein the system controller issues a SNMP (Get) message to obtain network management information from a WTRU.

5. The method of claim 4 wherein the base station responds to the system controller after fetching the requested network management information from a database in the base station wherein network management information for the WTRU is stored after being obtained by the base station from the WTRU using a MAC messaging protocol.

6. The method of claim 5 wherein the MAC messaging protocol is 802.11k.

7. The method of claim 3 wherein the system controller issues a SNMP (Trap) message to set at least one parameter of the WTRU.

8. The method of claim 7 wherein the base station translates the SNMP (TRAP) message to an 802.11k message and transmits the translated message to the WTRU.

9. The method of claim 3 further comprising the step of transmitting a message from the system controller directly to the WTRU to set at least one parameter in the WTRU.

10. The method of claim 9 wherein based on said message, the WTRU is configured to automatically set the at least one parameter to a predetermined value when a predetermined event occurs.

11. The method of claim 1 wherein the application level network management protocol is extended markup language (XML).

12. A wireless network comprising:

a system controller configured to send and receive network management information using application level network management protocol messaging;

a plurality of wireless transmit/receive units (WTRUs) configured to send and receive network management information using a MAC messaging protocol; and

a base station configured to facilitate communication between the system controller and WTRUs wherein the system controller uses said application level network management protocol messaging and the WTRUs use said MAC messaging protocol.

13. The network of claim 12 wherein the base station further comprises a translator for translating back and forth between the application level network management protocol and the MAC messaging protocol.

14. The network of claim 12 wherein the application level network management protocol is simple network management protocol (SNMP).

15. The network of claim 14 wherein the system controller issues a SNMP (Get) message to obtain a management information base (MIB) from a WTRU.

16. The network of claim 15 wherein the SNMP (GET) message is sent to a base station and said base station translates the SNMP (GET) message to a MAC messaging protocol format and forwards the SNMP (GET) message to the WTRU.

17. The network of claim 16 wherein the WTRU sends its MIB to the base station in the MAC messaging protocol format and the base station translates the MIB to SNMP and sends the translated MIB to the system controller.

18. The network of claim 15 wherein the base station is configured to periodically obtain the MIB of WTRUs associated with the base station and store them in memory.

19. The network of claim 18 wherein the MIBs are stored in translated format and the base station is configured to respond to SNMP (GET) messages by selecting the appropriate MIB stored in memory and sending it to the system controller.

20. The network of claim 19 wherein the base station is configured to request MIBs from WTRUs whose MIBs have been stored in the base station'"'"'s memory more than a predetermined amount of time.

21. The network of claim 14 wherein the system controller issues a SNMP message to set at least one parameter of at least one WTRU.

22. The network of claim 14 wherein the SNMP message is translated by the base station and sent to the at least one WTRU and the WTRU sets the at least one parameter according to the SNMP message.

23. The network of claim 21 wherein the SNMP message is sent directly to the WTRU.

24. The network of claim 21 wherein the SNMP message instructs the WTRU to set certain parameters of the WTRU to default values where a predetermined event occurs in the WTRU.

25. The network of claim 12 wherein the application level network management protocol is extended markup language (XML).
