Abstract

A system and method of providing dynamic redundancy of home location registers (HLRs) for a plurality of subscribers in a radio telecommunications network having a plurality of HLRs (11-15), each of which has excess memory capacity for storing subscriber records. Each of the HLRs in the network operates as both a primary HLR and a secondary HLR. Subscriber records (10) in each HLR are divided into a plurality of subsets of known size. For each subset of records in a particular HLR, another HLR in the network is designated as the secondary HLR. The primary HLR (11) and the secondary HLR (12) for each subscriber are identified to the network through new subscriber categories. A heartbeat signal is periodically sent back and forth between the primary HLR and the secondary HLR in each HLR pair to convey the operational status of each HLR in the pair. If the heartbeat signal is not received in a secondary HLR, the secondary HLR sends to the network a Qualification Directive (QUALDIR) Invoke message directing the network (21) to utilize the secondary HLR sending the message as the new primary HLR for the assigned subset. The secondary HLR records all changes made to its subscriber records until the primary HLR is operational, and the heartbeat signal is resumed. The secondary HLR then updates the primary HLR, and the primary HLR is redesignated as the primary HLR.
