Roaming interworking gateway for mobile telecommunications systems
First Claim
1. A roaming interworking gateway for interworking of at least two mobile telecommunication systems having non-compatible standards, the gateway comprising:
- a modular unit associated with a first mobile system and comprising a pseudo network element for the first system;
a modular unit associated with a second mobile system and comprising a pseudo network element for the second system; and
an interworking translation function linking the modular units and comprising means for performing data and protocol conversion between the units, wherein each said modular unit of said first and second mobile system comprises a MAP interface comprising a signalling stack, a MAP-provider residing on the signalling stack, and a MAP-user residing on the MAP-provider and comprising means for accessing a database, the interworking translation function includes a database comprising means for receiving and storing a subscriber identifier for each mobile system, a translation module residing on the MAP-user of each said modular unit of said first and second mobile system, and comprising means for accessing said database, each said translation module comprising means for registering a roaming subscriber upon receipt of a registration notification signal comprising the steps of automatically transmitting a location update signal to the home system, receiving a subscriber profile from the home system, and storing the received subscriber profile in the database, and means for handling subsequent notifications from a registered subscriber with reference to the stored subscriber profile.

Abstract
A roaming interworking gateway has a modular unit associated with an IS.41 system, a modular unit associated with a FSM system, and a translation function. The translation function accesses a database which stores subscriber data upon registration of a subscriber in a roamed mobile system. Each modular unit comprises an authentication center to perform authentication before registration. The RIG is implemented on a distributed hardware structure having a high-speed network to which are connected network access processors (NAP), database servers, and an operations and maintenance processor. Each modular unit resides on a single network access processor. The translation function has a module residing on the NAP of each associated modular unit.
