Allocation of frequency channels in a network of microcells and macrocells wcdma.

摘要

A mobile communications network of division multiple access CDMA code in which a geographical area covered by the network is divided into macrocells and each macrocell has a node, whereby communications to and from a mobile terminal in a macrocell may be performed through its node in one or more of a plurality of frequency channels (frequency 1, frequency 3) allocated to the macrocell, wherein at least one macrocell has a defined microcell therein having its own node, whereby communications to and from a mobile terminal in a microcell may be made via its node over one or more of a plurality of frequency channels (frequency 1, frequency 2) allocated to the microcell sharing the microcell at least one channel frequency (frequency 1) with its macrocell and sharing at least one macrocell and the microcell a frequency channel not shared (frequency 2, frequency 3), face cterizada network by: means arranged to allocate a frequency channel shared (Frequency 1) to a call if the shared frequency channel has sufficient capacity and arranged to allocate a channel of unshared frequency (Frequency 2, Frequency 3) to a call only if the or each shared frequency channel have insufficient capacity.
