A radiocommunication system balances interference reduced by soft handoff with access network loading increased by soft handoff. When the access network loading exceeds some threshold for a particular transmission source, then the system limits or reduces that source's soft handoff connections with remote stations.

Method and system for soft handoff control based on access network capacity

The present invention relates to systems and methods for allocating channels in a radiotelephone system wherein local estimation of interference for a potential new connection is achieved by measuring interference on the available downlink channels at a plurality of locations within a cell. The measurements can be made, for example, by already connected mobile stations, mobile stations which are not connected, fixed measurement stations or any combination thereof.

Mobile assisted channel allocation

A method for adaptively allocating channels for connections between base station and mobiles is disclosed. The channels accessible to the base stations for establishing connections with mobiles are ranked in at least one priority list based on transmission loss intervals. Each channel is ranked in the priority list according to their success at previous connections. The amount of power required for a channel allocated from a list associated with a low transmission loss can be set lower thereby reducing the interference associated with the channel and increasing system capacity. A self planned system evolves where channels are allocated for connections based on their past connection history. Thus, the selection of channels which may interfere with calls in neighboring cells or which may suffer substantial interference from a neighboring base is avoided.
