Abstract: In a mobile network a packet interface (103) is monitored by a tap (160-163) in a non-intrusive manner. Captured transaction data is uploaded to a probe (155-158) linked to one or more taps. The probe acts as a slave to a server (159), activating and terminating data capture. A coordinator (601) of the probe (155) manages data capture and buffering according to the server. The server (150) filters the data according to a subscriber registry (203) and loads data until there are complete protocol descriptions. These provide real time subscriber-centered QoS metrics.

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.

Abstract: A HLR (10) has a bus (11) which interconnects a NAP layer (12), a DBS layer (13) and an OMP layer (14). All accesses to a memory database (26) are through a single channel—the associated DBS (25) with associated databases (26, 27). Each NAP (20) has a directory service (21) identifying the active DB (26) for each item of subscriber data. Each DBS (25) has a shadow DBS (25) to which it automatically writes for real time synchronization.
