  • Communication system architecture and method of routing therefor
    Patent number: 5854982
    Abstract: To alleviate the constraints imposed on communication system management by the assignment of dedicated ranges of MSISDNs and IMSIs to each particular home location register (HLR.sub.1, HLR.sub.2, HLR.sub.N), the present invention provides an ability to separate IMSIs and MSISDNs between HLR platforms by providing at least two databases (80-90) separated from one another and indexed in terms of ranges of MSISDNs and ranges of IMSIs, as illustrated in FIG. 5. A cross-reference (92, 95) is both stored within a particular MSISDN and a particular IMSI to maintain an association therebetween, thereby allowing access to subscription information stored in at least one of the particular MSISDN and the particular IMSI.
