Abstract
An apparatus includes a home location register (203) that stores records for mobile units in a home system (201). A visited location register (213) stores records for mobile units presently registered in a visited system (211) in which the visited location register (213) is located. The visited system (211) identifies a last accessed technology by a mobile unit (221) in the visited system (211) and forwards the identification of the last accessed technology to the home location register (203). The identification of the last accessed technology may be forwarded to the home location register (203) in a registration notification. The home system (201) may forward a routing request including the identification of the last accessed technology to the visited system (213).
Claims32
A method comprising the steps of:
- receiving, at a visited system, a registration request to access the visited system via an access technology for a mobile unit that is associated with a home system having a home location register;
- forwarding, to the home location register, a registration notification including an identification of the access technology.
A method comprising the steps of:
- receiving, at a visited system, a registration request to access the visited system via a first access technology for a mobile unit that is associated with a home system having a home location register;
- receiving, at the visited system, a registration request to access the visited system via a second access technology for the mobile unit;
- forwarding, to the home location register, a registration notification including an identification of the second access technology.
A method comprising the steps of:
- receiving, at a home system, call activity for a mobile unit that has a last known location at a visited system;
- determining which access technology the mobile unit last used to access the visited system;
- forwarding, to the visited system, a route request including the access technology;
- routing, via the visited system, the call activity to the mobile unit in a format consistent with the access technology.
A method comprising the steps of:
- receiving, at a visited system, a route request including an access technology used by a mobile unit;
- forwarding a routing number to a home system for the mobile unit;
- routing call activity to the mobile unit in a format consistent with the access technology.
A method comprising the steps of:
- receiving, at a home system, call activity for a mobile unit that has a last known location at a visited system;
- determining a mobile protocol capability indicator for the mobile unit;
- forwarding, to the visited system, a route request including the mobile protocol capability indicator;
- paging the mobile unit according to a technology in the mobile protocol capability indicator.
An apparatus comprising:
- a home location register, arranged and constructed to store records for one or more mobile units in a home system;
- a visited location register, arranged and constructed to store records for one or more mobile units presently registered in a visited system in which the visited location register is located;
- wherein the visited system is arranged and constructed to identify a last accessed technology by a mobile unit in the visited system and forward the identification of the last accessed technology to the home location register.
