Co-operative solutions for inter-mode monitoring in re-configurable terminals

Re-configurable terminals, by definition, are intended to work across multiple telecommunications systems and standards. One of the requirements to be able to achieve this is the ability to monitor levels of coverage in alternative systems. There are limited opportunities for performing alternative mode monitoring within existing standards; therefore other approaches need to be investigated. This paper investigates the concept of co-operative mode monitoring (CoMM), whereby measurements taken by "donor" terminals in the destination mode are presented to the "roaming" terminal.
