Abstract
A communication network (100) is provided having a public and private network with a virtual home location registry. Generally, the public network (102) includes a public wireless network (112) with a public mobile switching center (MSC 114) The corporate network (104) includes a number of corporate wireless networks (106) located at a number of sites (110) each coupled to the public MSC (114), and several or all of the corporate wireless networks having a physical HLR (108). The corporate wireless networks (106) are coupled via an IP network (130) to one another and to an HLR management function (128). An corporate network operation management controller (OMC 126) is coupled to the public MSC (126), and to the routing function (128). The routing function (128) is configured to route access requests from the OMC (126) to the physical HLRs (108), and the OMC is configured to manage the physical HLRs to provide a single virtual HLR for the corporate wireless networks (106).
