  • Home location register controller capable of dealing with congestion without restriction of access
    Patent number: 6314291
    Abstract: A home location register controller comprises a monitoring section and a main control section. The monitoring section is connected to an active home location register to monitor simultaneous access from a mobile services switching center to the active home location register. The monitoring section produces a monitoring signal representative of the number of the simultaneous access. The main control section is connected to the monitoring section and the mobile services switching center and decides whether congestion is happened in the active home location register or not on the basis of the monitoring signal. The main control section partially changes destination of access produced by the mobile services switching center from the active home location register to a standby home location register.
