Method of fast dynamic channel allocation call admission control for radio link addition in radio resource management
First Claim
1. A method for call admission control for radio link addition in a fast dynamic channel allocation 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 new 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 fast dynamic channel allocation call admission control for radio link addition includes a pre-code allocation process, a signal-independent code allocation process, and a post-code allocation process. The pre-code allocation process receives and processes a request message, retrieves the new cell identification from the message, and retrieves the old cell identification and system information from a centralized database. The code allocation process checks the availability of a code set in the new cell, generates timeslot sequences for the available timeslots, and assigns a code set to the available timeslots in a timeslot sequence, wherein a successful assignment is a solution. The interference signal code power (ISCP) is calculated for each solution and the solution having the lowest weighted ISCP is selected as an optimal solution. The post-code allocation process stores the new radio link information in the database and creates a response message with new allocation information.

8. A method for call admission control (CAC) for radio link addition in a fast dynamic channel allocation wireless communication system, comprising the steps of:
-
receiving a request message to initiate the CAC function; processing the request message; retrieving Node B measurements from a centralized database; reading wireless transmit/receive unit (WTRU) coded composite transport channel (CCTrCH) information and dedicated channel information from the centralized database; retrieving WTRU capability information from the centralized database; retrieving a list of available timeslots in the new cell from the centralized database; retrieving data rates for CCTrCHs from the centralized database; retrieving a list of code sets for the requested data rate from the centralized database; allocating the code sets to the available timeslots in the new cell; storing the new radio link (RL) information and allocation information in the centralized database; and creating 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)
