A wireless mobility services platform (1) has a high-speed network interconnecting an operations and maintenance processor (2) for performing platform administration and management functions, a network access processor for handling signalling traffic, and a database server (4) comprising a memory subscriber database distributed across hardware platforms according to a fault-tolerant redundancy scheme. A platform software layer (12) comprising common communication and database access functions is hosted on the operations and maintenance processor, the network access processor, and on the database server. A signal relay layer (13) is hosted on the network access processor.
