Abstract: A loop protection mechanism including dynamically determining a link connecting two adjacent nodes of a loop in a communication network in accordance with a predefined criterion, and reconfiguring the loop so that the loop is broken at the determined link which is an optimal link in terms of the predefined criterion. The breaking of the loop enables for example to utilize loop-free technologies (e.g. Ethernet) in a physical loop architecture.

Abstract: In a system handling communication between base transceiver stations (BTS1-BTS12) and base station controllers (BSC) of a cellular radio network the transmission capacity is composed of a predetermined number of capacity units (T0-T31). At least one capacity unit (TCH) can be allocated to a given base station group which comprises at least two base transceiver stations. Said capacity unit is allocated to a certain base transceiver station in the base station group when the instantaneous volume of traffic handled by said base transceiver station requires temporary allocation of additional capacity, and said capacity unit is again released so as to be allocatable to the base station group when the instantaneous volume of traffic handled by said base transceiver station no longer requires temporary allocation of additional capacity.
