- 2. A controlling radio network controller according to claim 1, wherein said cell data includes a cell record having
a cell identification field; a cell status field; a timeslot record for each timeslot; a cell-based operations and maintenance configuration data field; call admission control function parameters; and a power control information field.
- 3. A controlling radio network controller according to claim 2, wherein each timeslot record includes
a timeslot number field; a channel type field; a channel direction field; a list of allocated codes; an available resource units field; and a code vector field.
- 4. A controlling radio network controller according to claim 3, wherein said list of allocated codes includes a cell code record having
a dedicated physical channel identification field; a code number field; a WTRU identification field; a radio link identification field; and a coded composite transport channel identification field.
- 5. A controlling radio network controller according to claim 3, wherein said code vector field includes an uplink code vector record having
a code identification field; a code block status field; and a code usage status field.
- 6. A controlling radio network controller according to claim 3, wherein said code vector field includes an downlink code vector record having
a code identification field; and a code usage status field.
- 7. A controlling radio network controller according to claim 1, wherein said WTRU data includes a WTRU record having
a WTRU identification field; a WTRU capability field; and a radio link information field.
- 8. A controlling radio network controller according to claim 7, wherein said radio link information field includes a radio link record having
a radio link identification field; a cell identification field; an uplink coded composite transport channel (CCTrCH) information field; and a downlink CCTrCH information field.
- 9. A controlling radio network controller according to claim 8, wherein said uplink CCTrCH information field and said downlink CCTrCH information field include a CCTrCH record having
a CCTrCH identification field; and a dedicated physical channel (DPCH) information field.
- 10. A controlling radio network controller according to claim 9, wherein said DPCH information field includes a DPCH record having
a repetition period field; a repetition length field; and a DPCH timeslot list.
- 11. A controlling radio network controller according to claim 10, wherein said DPCH timeslot list includes a DPCH timeslot record having
a timeslot number field; a midamble shift and burst type field; a transport format combination indicator presence field; and a code list.
- 12. A controlling radio network controller according to claim 11, wherein said code list includes a WTRU code record having
a DPCH identification field; a code usage status field; a CCTrCH identification field; a code number field; and a code signal to interference target field.
- 13. A method for improving the performance of radio resource management (RRM) functions in a wireless communications system, comprising the steps of:
providing a data storage; storing resource allocation information for the wireless communications system in the data storage; accessing the data storage by a RRM function, wherein the RRM function obtains current resource allocation information for the wireless communications system; performing the RRM function; and updating the data storage based upon changes to the resource allocation in the wireless communications system made by the RRM function.
- 14. The method according to claim 13, wherein the providing step includes providing a centralized data storage in a controlling radio network controller.
- 15. The method according to claim 13, wherein the storing step includes storing operation and maintenance data in the data storage.
- 16. The method according to claim 13, wherein the storing step includes storing cell-specific data in the data storage.
- 17. The method according to claim 13, wherein the storing step includes storing wireless transmit/receive unit-specific data in the data storage.
- 18. The method according to claim 13, wherein the RRM function is a call admission control routine.
- 19. The method according to claim 13, wherein the RRM function is an escape mechanism.
- 20. The method according to claim 13, wherein the RRM function is a background interference reduction function.
- 21. A method for improving the performance of a call admission control (CAC) routine by storing commonly used data in a central database, the method comprising the steps of:
initializing the central database; receiving operations and maintenance (OA&M) data; storing the OA&M data in the central database; triggering the CAC routine; retrieving cell data and wireless transmit/receive unit data from the central database, the retrieved data to be used by the CAC routine; executing the CAC routine and allocating resources to the newly admitted call; and storing information regarding the resources allocated to the newly admitted call in the central database.
