Method for implementing fast-dynamic channel allocation call admission control for radio link reconfiguration in radio resource management
First Claim
1. A method of implementing a fast dynamic channel allocation call admission control for radio link reconfiguration in a wireless communication system, comprising:
- a pre-code allocation process;
a signal-independent code allocation process, including;
checking the availability of a code set in the cell;
generating timeslot sequences for the available timeslots;
assigning a code set to the available timeslots in a timeslot sequence, wherein a successful assignment is a solution;
calculating the interference signal code power (ISCP) for each solution; and
selecting the solution having the lowest weighted ISCP as an optimal solution; and
a post-code allocation process.

Abstract
A method of implementing fast dynamic channel allocation call admission control for radio link reconfiguration in a wireless communication system includes a pre-code allocation procedure, a signal-independent code allocation procedure, and a post-code allocation procedure. The pre-code allocation procedure receives and processes a request message and retrieves system measurements and wireless transmit/receive unit (WTRU) capability information from a centralized database. A list of available timeslots and a list of code sets is retrieved from the centralized database. The code sets are allocated to the available timeslots, wherein a successful assignment is a solution. The solution having the lowest weighted interference signal code power is an optimal solution. The WTRU information with new allocation information is updated in the centralized database. A radio link reconfiguration ready message with the results of the code allocation process is then sent.

8. A method of implementing fast dynamic channel allocation call admission control (CAC) for radio link reconfiguration in a wireless communication system, comprising the steps of:
-
receiving a radio link reconfiguration request message to initiate the CAC function; processing the request message; obtaining Node B measurements from a centralized database; defining a local data structure to store measurement data; retrieving a list of available timeslots and a list of code sets from the centralized database; retrieving wireless transmit/receive unit (WTRU) capability information from the centralized database; allocating the code sets to the available timeslots in a timeslot sequence; updating the new WTRU information with new allocation information in the centralized database; and sending a response message with the results of the code allocation process. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32)
