  • Patent number: RE45984
    Abstract: A method for setting up a radio traffic channel in a 3G-network shared between at least two operators. The network's traffic channel resources are divided into operator specific parts, the parts not sharing any common traffic channels. User equipment is allocated channel resources in accordance with it's associated operator, according to a coarse level allocation control, which may be overridden in case no idle traffic channels are available. The allocated traffic channel is preferably associated with the user equipment operator and is furthermore idle in as a large area as possible and/or exhibits an optimum QoS, thereby maximizing network capacity and throughput by minimizing the probability of inter-frequency handover signalling and compressed mode operations. A radio network controller includes installed software, which carries out the traffic channel allocation and control.
