In a very wide area communication system, there may be a centralized database (Home Location Reg- ister) which stores master copies of all subscribers attributes and several local databases (Visitors Loca- tion Register) which store local copies of the subscriber attributes. When a subscriber roams into an area controlled by a VLR, the HLR will then send the subscriber's attributes to the VLR. In a SmartZone OmniLink system (a very wide area radio communication system), the VLR will assign very restrictive attributes to the subscriber until the mas- ter copy of the subscriber data is received from the HLR.
