Abstract
The present invention relates to optimized radio resource utilization in a cellular telecommunication system. A base station of such a system evaluate a capacity metric of the base station and capacity metrics of neighboring base stations. In response to detecting that the capacity metric of the base station is below a threshold with respect to the capacity metrics of the neighboring base stations, the base station enters a stand-by mode and releases its radio resources that essentially define a cell associated with the base station so that the released radio resources become available for allocation to at least one of the neighboring base stations.
Claims26
A method comprising:
- evaluating, in a base station of a cellular radio access network operating on a radio resource, a capacity metric of the base station with respect to the radio resource and capacity metrics of neighboring base stations with respect to the radio resource;
- and
- in response to detecting that the evaluated capacity metrics indicate that the capacity of the base station is below a threshold calculated from the capacities of the neighboring base stations on said radio resource, configuring the base station to enter a stand-by mode and to release said radio resource that defines a cell associated with the base station so that the released radio resource becomes available for allocation to at least one of the neighboring base stations.
An apparatus comprising:
- one or more processors;
- and
- one or more memories including computer program code, the one or more memories and the computer program code configured, with the one or more processors, to cause the apparatus to perform the following:
- evaluate a capacity metric of a base station of a cellular radio access network operating on a radio resource and capacity metrics of neighboring base stations, wherein the capacity metrics are evaluated for said radio resource;
- and
- in response to the capacity evaluation circuitry detecting that the capacity of the base station is below a threshold to calculated from the capacities of the neighboring base stations on said radio resource, configure the base station to enter a stand-by mode and to release said radio resource that defines a cell associated with the base station so that the released radio resource becomes available for allocation to at least one of the neighboring base stations.
An apparatus comprising:
- a capacity evaluation circuitry configured to evaluate a capacity metric of a base station of a cellular radio access network operating on a radio resource and capacity metrics of neighboring base stations, wherein the capacity metrics are evaluated for said radio resource;
- and
- a communication control circuitry configured, in response to detecting that the capacity of the base station is below a threshold calculated from the capacities of the neighboring base stations on said radio resource, to configure the base station to enter a stand-by mode and to release said radio resource that defines a cell associated with the base station so that the released radio resource becomes available for allocation to at least one of the neighboring base stations.
