Claim:
1. A method of allocating frequencies in a radio access network (RAN) that includes a plurality of radio nodes each associated with a cell and a services node operatively coupled to the radio nodes, the method comprising: dividing the radio nodes (RNs) in the RAN into a plurality of clusters of RNs; generating a fractional frequency reuse (FFR) pattern for each cluster; allocating transmission resources to the radio nodes in each cluster in accordance with the respective FFR pattern that is generated for each cluster, wherein dividing the RNs into the plurality of clusters is performed by the services node, the services node providing connectivity to a core network, wherein the cell associated with each RN includes a cell interior and a cell edge and generating the FFR pattern for each cluster includes allocating a common center band of frequencies to the RNs for use by UEs in the cell interior of each cell in each cluster and cell edge frequencies are allocated to the RNs for use by UEs transmitting or receiving high priority messages.
