Radio resource controller preserving communication in an out-of-coverage area

A radio resource controller (RRC) for use in a radio cell to preserve communication in an out-of-coverage (OOC) area not covered by the radio cell, the RRC comprising:

• a processor, configured to:
• determine an egress traffic of mobile communication devices from an area covered by the radio cell to the OOC area, determine an ingress traffic of mobile communication devices, from the OOC area to the area covered by the radio cell, determine a demand of radio resources for services running on mobile communication devices entering the OOC area, and control admission of the services running on the mobile communication devices entering the OOC area, and schedule radio resources for admitted services based on an admission and scheduling metric that takes into account the egress traffic, the ingress traffic, and the demand of radio resources, wherein the OOC area comprises a delimited out-of-coverage (DOC) area, and wherein the processor is configured to admit and schedule non-overlapping radio resources running on the mobile communication devices entering the OOC area in response to determining that a radius of the DOC area is less than a communication range of the mobile communication devices.
