Patent ID: 7668078

Claim:
A method of allocating Walsh codes to support calls over fundicated channels (FC) and supplemental channels (SCH) in a wireless communication network, wherein a base station allocates Walsh codes from n Walsh spaces numerically identified from 1 to n and further wherein each Walsh space comprises one or more Walsh codes, the method comprising: if there is a first incoming call to be established over a FC: selecting, in the base station, a first FC Walsh space to support the first FC call from a first group of the Walsh spaces, comprising the (n-m) Walsh spaces numerically identified from (m+1) to n, wherein n and m are integers, and further wherein m<n; or selecting, in the base station, a first FC Walsh space to support the first FC call from the m Walsh spaces numerically identified from 1 to m if the first group of the Walsh spaces are not capable of supporting the first FC call; allocating, in the base station, a Walsh code in the first FC Walsh space to support the first FC call; and marking, in the base station, the first FC Walsh space with a first time field having a time associated therewith if the first FC Walsh space is one of the Walsh spaces numerically identified from 1 to m.
