Abstract
Methods and systems for setting-up channels in third generation (3G) communication systems that utilize wideband, code division multiple access signaling protocols including the reserving of a branch of the channelisation code tree to set-up the channels. By reserving a branch of the tree, the channels can be automatically coded using the pre-reserved codes in the branch which eliminates the need for separate verification procedure to be performed to determine whether there are enough transport layer resources available to accommodate the new channel and whether the new channel will disturb or otherwise interfere with current channel data transport. Since the new channels are set-up using reserved codes, the transport layer resources already exist to accommodate the new channels and there can be no chance of existing channel interference.
