A wireless communication network includes at least two programmable application processors (APs) for message processing. Each AP runs one or more active radio control software (RCS) instances on behalf of a defined cell group and one or more standby RCS instances on behalf of at least one other cell group. Each cell in the network is connected to a pair of APs. One AP runs an active RCS instance on behalf of the cell and the other AP runs a standby RCS instance on behalf of the cell. What is disclosed is a system and method for performing dynamic load balancing during system operation between a pair of APs (AP pair) serving at least one cell in common. In a first step, selection is made, relative to at least one cell served by the AP pair, of a first RCS instance running as an active RCS instance on one member of the AP pair and a second RCS instance running as a standby RCS instance on the other member of the AP pair. The first RCS instance is redesignated as a standby RCS instance for the cell and the second RCS instance is redesignated as an active RCS instance for the cell. Active message processing is then transferred from the first RCS instance to the second RCS instance during network operation and without service interruption to the cell. In a variation the foregoing, an entire group of RCS instances (active or standby) can be moved from one AP to another. Also disclosed is a distributed mated-pair processor arrangement in which the standby RCS instances for a cell group are distributed across multiple APs.
