Abstract: Management of native subscriber registrations on a foreign network is accomplished via an approach that advantageously offers dynamic roaming, that is, the capability to send data over-the-air to populate a customer subscriber identity module (SIM) card with specific networks, in a specific order of preference, according to the characteristics and capabilities of the subscriber mobile station, the subscriber's home network, the foreign territory roamed, and the like. The approach also provides an SS7 service-based solution including the capability of the home network to control the roaming mobile station from registering on a non-preferred visited network, based on configurable rules.

Abstract: A method, such as a method for doing business, is provided. The method includes providing telecommunications dialing features such as, for example, call return, call waiting and speed dialing, for commercial classes of telephone service. The method may include providing the telecommunications dialing features for commercial classes of telephone service on dedicated phone lines, such as a T-1 circuit. The method may also include charging a customer for providing the telecommunications dialing features for commercial classes of dedicated telephone service. According to one embodiment, the method includes charging the customer a fee on a periodic basis for the dialing features.

Abstract: A method and apparatus for routing calls that receives a call, identifies the subscriber, determines the preferred call carrier, and routes the call to a line connected to the preferred call carrier, all before the call enters the region between local access transport areas. The invention comprises a digital cross-connect system, a computer with a database connected to the digital cross-connect system, and a service management system connected to the computer. The service management system programs the computer with routing information that corresponds to the subscriber's calling plan. The digital cross-connect system receives calls and sends them to the computer. The computer identifies the call information and uses a routing table to determine the correct call carrier for the call. The computer sends the call with routing information back to the digital cross-connect system where the call is routed to the appropriate local or interexchange carrier, e.g., a local network or long distance carrier.
