Control mechanism for common control channel use

摘要

A method and elements for optimally utilizing a common control channel for delivery of service related information without risking the prioritized communications of the network users. A network node communicates with radio terminals at least part of which comprise a service application transmitting information over a common control channel of their present base station. The invention is based on the idea of measuring load of a common control channel in the network side, and controlling transmissions of the service related messages in the radio terminals that reside in the base station according to the measured load. Due to the invention, the amount of load incurred by a service can be adjusted dynamically according to varying communication situations in individual base stations.
