Wireless communication systems and methods for updating locating information of mobile station using multicast
First Claim
1. 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:
- at least one zone controller of said plurality of zone controllers being operable to transmit a multicast message to a plurality of said short data routers such that at least one short data router of the plurality of said short data routers is operable to generate or update information relating to mobile communication units that are operational in the at least one zones that the short data router serves.

Abstract
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.

10. A method for improving redundancy provision in a wireless zone-based communication system comprising a plurality of zones being served with short data capabilities by a plurality of short data routers, the method being characterised by the steps of:
-
transmitting a multicast message from a zone controller to a plurality of short data routers;
receiving said multicast message at one of said plurality of short data routers; and
generating, by said short data router, at least one mobility database for mobile units that are operational in the one or more zones served by said short data router. - View Dependent Claims (11, 12)
