A wireless zone-based communication system (200, 300) includes a plurality of zones (150-158) being served with short data capabilities by a plurality of short data routers (220-224). At least one zone controller (210) from a number of zone controllers transmits a multicast message (430, 440) to the plurality of short data routers (220-224). At least one short data router (220) is able to generate or update information relating to mobile communication units that are operational in the one or more zones the short data router (220) serves. Preferably, the short data router serves as a primary and/or secondary (back-up) and/or load sharing short data router. A method for improving redundancy provision in a wireless zone-based communication system (200, 300), a zone controller (210) and a short data router (220) are also described.
A wireless zone-based communication system comprising a plurality of zones being served with short data capabilities by a plurality of short data routers, wherein the plurality of short data routers are operably coupled to a plurality of zone controllers, the wireless zone-based communication system being characterised by:
