Replicated distributed directory services for mobile communications networks

Abstract

The introduction of mobility into communications networks requires the provision of network-wide information services in order to: enable the mobility service itself; support applications on mobile computing and communications devices; and support users of mobile equipment. To implement these services network-wide, a common platform consisting of a distributed directory service like X500 can be used. One important aspect of these new services is their availability, since in many communications networks the availability requirements are extremely high.<>
