Data handling system
First Claim
1. A data storage unit for a mobile telecommunications system comprising at least two functions, providing data redundancy therebetween, at least two control functions, and transfer means for enabling the data storage unit to pass data to and from a mobile telecommunications network, the at least two control functions each having arranged to control the passing of data between both of said at least two data functions and said transfer means and to control updating of at least one of the data functions, wherein the at least two control functions are physically separate from the at least two data functions.

Abstract
In order to store data in a mobile telecommunications system, a data storage unit (HLR) has data functions (72, 74) providing data redundancy therebetween, control functions (79, 80) and signalling point (30, 31, 32) to enable the data storage unit to pass data to and from a mobile telecommunications network under the control of the control function. The control functions are physically separate from the data functions. The data functions (72, 74) may operate on the basis that one has a primary data function, a second has a primary standby function to achieve synchronised updating. The use of separate and hence distributed functions enables greater flexibility in the retrieval of data from the data storage unit (HLR).

A data storage unit for a mobile telecommunications system comprising at least two data functions, providing data redundancy therebetween, at least two control functions, and transfer means for enabling the data storage unit to pass data to and from a mobile telecommunications network, the at least two control functions each being arranged to control the passing of data between both of said at least two data functions and said transfer means, wherein the at least two control functions are separate from the at least two data functions, and said at least two data functions comprise a first data function being a primary data function, and a second data function having a primary standby data function, the primary data function being arranged to generate signals under control of either of said two control functions for synchronized updating of all of said data functions, and the primary standby data function being arranged to generate signals under control of either of said two control functions for synchronized updating of all of said data functions in the event of a failure to said primary data function.
