1. A computer implemented method for managing radio resources used by a User Equipment, UE, in a cellular communication network, the communication network comprising a plurality of radio resources, each radio resource defining a dimension of a multidimensional radio space over which the communication network extends, the method, performed by the UE, comprising:
obtaining, from a management node of the communication network, a distributed resource management model for a region of the communication network in which the UE is located, the distributed resource management model comprising a radio coverage model including defining radio characteristics of radio zones in the region, a radio zone comprising a portion of the multidimensional radio space over which the communication network extends that is defined by a particular combination of radio field characteristics, and each cell of the communication network comprises a plurality of radio zones;
performing a measurement of communication network radio resources;
assigning a current radio location of the UE to a radio zone of the communication network on the basis of the measurement, assigning a current radio location of the UE to a radio zone of the communication network on the basis of the measurement comprising:
classifying a vector of results of the measurement into a radio zone; and
assigning a current radio location of the UE to the radio zone into which the vector is classified;
updating a radio trajectory record of the UE's trajectory with the radio zone to which the current radio location of the UE is assigned;
using the distributed resource management model and the updated trajectory record to identify a radio resource action for execution by the UE; and
initiating execution of the identified radio resource action.
