Title:
SCALABLE WIRELESS NETWORK ARCHITECTURE BASED ON SUBSCRIBER DISTRIBUTION
Document Type and Number:
WIPO Patent Application WO1999008392
Kind Code:
A3
Abstract:
A wireless communication system (100) according to the present invention assigns mobile units (38, 136, 140) to one of a plurality of mobile switching centers (104, 106, 108) to equalize loading. A dispatching switch (102) couples the base station system to the mobile switching centers (104, 106, 108) and performs mobile unit assignments. The dispatching switch (102) determines the loading of each one of the mobile switching centers (104, 106, 108) and assigns mobile unit to a mobile switching center (104, 106, 108), the "serving" mobile switching center. Once a mobile switching center (104, 106, 108) is determined and during subsequent calls, the dispatching switch (102) establishes a transparent path between the base station controller (110, 112, 114, 116) servicing the call and the serving mobile switching center (104, 106, 108). In another construction, each of the base station controllers (110, 112, 114, 116) and each of the mobile switching centers (104, 106, 108) includes additional equipment which performs a portion of the operations of the dispatching switch (102). The network may be dissimilar to a conventional data structure supported by the wireless communication system (100).
