A method of implementing a fast dynamic channel allocation escape
procedure 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 measurement trigger signal, retrieves system
measurements from a centralized database, and determines physical
resources to be reassigned. The code allocation procedure checks the
availability of a code set in the cell and generates timeslot sequences
for the available timeslots. A code set is assigned 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 procedure
stores the reallocation information in the centralized database and
creates a physical channel reconfiguration request message.
