Abstract: 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.

Abstract: A short message gateway comprises a gateway function (SMGF) and programs in an HLR or a home network (IMT-2000). It does not have any physical impact on a foreign (PDC) network, and it converts short messages communicated between the home and foreign networks. The gateway function (SMGF) primarily inter-operates with an HLR and an SMSC of the home network, the GMSC providing the link to the foreign network. The gateway allows communication in a wide variety of scenarios for communication with subscribers in the home and foreign networks and roaming subscribers from one to the other.

Abstract: A roaming subscriber transmits a feature code when in a visited network (2). The MSC (4) routes it to the home network (1), where it is intercepted by a server (5). The server (5) determines that a pre-paid call is being requested and routes a request to a pre-pay platform (7), by-passing the HLR (6). The pre-pay platform (7) sets up the call.
