Abstract

This invention relates to an information network such as a telepoint network, having discrete communications units, such as telephone communications handsets (14), where each unit has a user-inaccessible memory. The invention also applies to networks of other units, such as smart cards. The network has regional controllers (11 and 12) for funnelling information from base stations (10) into a central controller (13). At the central controller, analysis of past communications is carried out and, based upon this, instructions are sent out to selected regional controllers for programming the memories of selected regional controllers for programming the memories of selected discrete units when those discrete units next communicate with base stations associated with the selected regional controllers.

Claims

1. An information network comprising:

a central controller;

a plurality of regional controllers connected for communication with the central controller;

a plurality of remote communications terminals divided into regions, each region comprising a plurality of such terminals served by a regional controller by being connected for communication therewith; and

a plurality of discrete information units, each comprising a user-inaccessible memory programmable only by means of a remote communication terminal characterized in that;

the central controller comprises means for generating a list of unit identification numbers (U.I.N.s) each U.I.N uniquely identifying a discrete information unit, means for correlating each U.I.N. with at least one regional controller based upon past communication between the discrete information unit and remote communications terminals in the region served by the regional controller, and means for transmitting the U.I.N.s on the list to only those regional controllers with which they are individually correlated,

each regional controller comprises means for storing those U.I.N.s in a regional list and means for transmitting its regional list to terminals in the region it serves and

each remote terminal comprises means for programming a user-inaccessible memory of a discrete information unit on the regional list stored thereby when that discrete information unit next communicates with that remote terminal.

2. A network according to claim 1, wherein means are provided at the discrete unit for activating or substantially deactivating the ability of that unit to carry out communications when a remote terminal writes to the user inaccessible memory of that unit.

3. A network according to claim 2, wherein the remote terminal unit is provided with means for connecting the discrete unit to a communications network and the predetermined further communications include all connecting of the discrete unit to that network.

4. A network according to claim 2, wherein the remote terminal is provided with means for connecting the discrete unit to a communication network and the predetermined further communications include all connecting of the discrete unit to that network for more than a predetermined time.

5. A network according to claim 2, wherein the remote terminal is provided with means for connecting the discrete unit to a communications network and the predetermined further communications include all connecting of the discrete unit to at least certain parts of that network.

6. A network according to any of claims 1 to 5, further comprising means for communicating U.I.N.s from the central controller to a regional controller for adding to or removing from the regional list stored at the regional controller.

7. A network according to claim 6, further comprising means for communicating information in addition to U.I.N.s from the remote terminals to the regional controllers and from the regional controllers to the central controller and means at the central controller for processing said information, generating information in response, including U.I.N.s to be added to or removed from the regional lists stored at the regional controllers and communicating said information to selected regional controllers.

8. A method of controlling the use of discrete information units in an information network comprising a central controller, a plurality of regional controllers connected for communication with the central controller and a plurality of remote communications terminals divided into regions, each region comprising a plurality of such terminals served by a regional controller by being connected for communication therewith, the method comprising the steps of:

generating a list of unit identification numbers (U.I.N.s) at the central controller, each number uniquely identifying a discrete information unit,

correlating, at the central controller, each U.I.N. with at least one regional controller based upon past communications between the discrete information unit and remote communications terminals in the region served by the regional controller,

transmitting the U.I.N.s on the list to only those regional controllers with which they are individually correlated,

storing those U.I.N.s at the regional controllers in regional lists,

transmitting the regional list stored by each regional controller to remote communication terminals in the region served thereby and storing that list at those terminals and

programming a user-inaccessible memory of a discrete information unit on the regional list of a remote terminal when that discrete information unit next communicates with that remote terminal.
