Abstract

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.

CONVERSION OF RESTRICTIVE ATTRIBUTES BY A LOCAL DATABASE UPON DATA PATH FAILURE

by Briana Hoffman and Mark Nielson

able for a subscriber to continue to operate with the restrictive privileges assigned before the communi- cations failure.

BACKGROUND

  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.

SOLUTION

PROBLEM

  If a VLR has temporarily assigned restrictive priv- ileges to a subscriber and the communication data path between the VLR and HLR fails, it is not desir-

  The VLR may either convert the restrictive set of privileges to a less restrictive set of privileges, or the VLR may remove the privileges all together as specified by an access flag configured by the system manager. Ifthe privileges are converted to less restric- tive privileges, then the subscriber will operate with the new set of privileges until the communication path between the VLR and HLR is restored. At that tim...
