Abstract
A controlling radio network controller (C-RNC) for use in radio resource management (RRM) functions includes a radio resource management function for managing radio resources. The RRM function uses data stored in a common database, including cell data and wireless transmit/receive unit (WTRU) data. The cell data includes resource assignment information for a cell, and the WTRU data includes WTRU capability and WTRU radio link information.
Claims21
A controlling radio network controller (C-RNC) for use in radio resource management (RRM) functions, the C-RNC comprising:
- a central database, including resource allocation information such as cell data including resource assignment information for a cell and wireless transmit/receive unit (WTRU) data including WTRU capability information and WTRU radio link information;
- a radio resource management function for managing radio resources, said radio resource management function using resource allocation information stored in said central database, said radio resource management function updating said central database based on changes to the resource allocation information made by said radio resource management function.
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.
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 it 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.
