摘要：In a mobile telephone network, a home location register (HLR) is provided withone or more cascaded home location registers to which some of the subscribers areallocated so as to share the workload in processing the subscriber information requeststhat are involved in the setting up of calls. Routing of requests to the correct HLR issimplified by routing all such requests to the original or master HLR and forwarding onlythose requests for which data is stored on one of the back-up or cascaded HLRs. Thisavoids the need for changes in the existing system routing plan. In a further embodimenttwo HLRs may form a mutually boosting pair.
