Communication system
First Claim
1. A base station for sharing resources of a communication bandwidth between a plurality of network operators including first and second network operators, the base station comprising:
- a defining circuit configured to define;
(a) a first operator proportion of the resources in said communication bandwidth, which first operator proportion represents a target average minimum proportion of the resources to be prioritized for communication bearers of the first network operator, over time;
(b) a second operator proportion of the resources in said communication bandwidth, which second operator proportion represents a target average minimum proportion of the resources to be prioritized for communication bearers of the second network operator, over time; and
(c) a shared proportion of the resources in said communication bandwidth, which shared proportion represents a proportion of the resources to be shared between communication bearers of the first network operator and communication bearers of the second network operator;
an admission control circuit configured to control admission of a new communication bearer into one of said first operator proportion, and said second operator proportion, in dependence on the size of an operator proportion for that specific network operator, upon optimizing the resources for transmitting and receiving data to and from a mobile communication device belonging to the plurality of network operators;
wherein said admission control circuit is operable to admit said new communication bearer when the following condition is met;
ρ
g+ρ
new<
ρ
g(th)tgrsv where ρ
g is an estimated current load represented by all communication bearers of network operator g;
ρ
new is an estimate of an expected additional load that will result if said new communication bearer is admitted;
ρ
g(th) is an operator specific threshold value expressed as a fraction of the respective proportion of the resources of operator g, selected between 0 and 1; and
tgrsv is the size of the proportion of operator g.

Abstract
A wireless telecommunication system is described comprising a shared base station able to divide resources between multiple network operators sharing the base station. The base station resources are divided into sets of resources reserved for each network operator respectively and resources shared by all network operators. The shared base station is configured to monitor the usage of its resources by each operator and to determine, for each scheduling round, an appropriate prioritization of communication bearers associated with the network operators.
