Abstract
Abstract In a telecommunications system such as a global mobile telephone network in which each subscriber unit includes a Subscriber Identity Module (SIM card), each SIM card has fixed memory locations (22), to which data can be addressed over the air. The locations (22) can be accessed from the subscriber unit on the entry of short simple codes, each associated with one of the locations. Further fixed memory locations (24) can be read over the air only when the subscriber enters a personal identification number. Also, the SIM contains means which are operable to act on receipt of a signal, from the user of the subscriber unit or from a host station, to determine and undertake an appropriate response to the signal. <IMAGE>

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
153 words
A telecommunications system comprising at least one host station (1) and a plurality of subscriber units the or each host station being operable to transmit a message to at least one of the subscriber units, and each subscriber unit having a multiplicity of fixed memory locations (22) and means responsive to the detection of the message to store the message in a selected one of the fixed memory locations, which can be accessed from the subscriber unit when required, said memory locations (22) being provided in an integrated circuit card (7) or other module which is removably connected to said subscriber unit, characterized in that each subscriber unit is adapted to transmit a signal, from the or each host station or the user of said subscriber unit, to said module, said module containing means operable to act on receipt of such a signal to determine and undertake an appropriate response to said signal.
Claim 2
Dependent Claim
36 words
A system as claimed in claim 1, wherein the or each host station (1) is operable to overwrite a message stored in any one of said multiplicity of fixed memory locations (22) at each subscriber unit.
Claim 3
Dependent Claim
51 words
A system as claimed in claim 1 or claim 2, wherein each subscriber unit comprises means arranged to receive a signal from said module and to present information from said signal to the user of said subscriber unit or to transmit said signal to at least one of said host stations.
Claim 4
Dependent Claim
102 words
A module (7) for controlling a subscriber unit in a telecommunications system having at least one host station (1), said module (7) being removably connectable to a transceiver (6) of the subscriber unit, and comprising a multiplicity of fixed memory locations (22,24), and means responsive to the detection of a message transmitted remotely thereto to store the message in a selected one of the fixed memory locations, characterized by response means operable to act on receipt of a signal, from the or each host station or the user of said subscriber unit, to determine and undertake an appropriate response to said signal.
Claim 5
Dependent Claim
25 words
A module (7) as claimed in claim 4, wherein said response means is arranged to request further information, such as a personal identification number (PIN).
Claim 6
Dependent Claim
38 words
A module (7) as claimed in claim 5, wherein said response means includes means for comparing said input information with information stored in said module, and means for determining a response dependent on the outcome of said comparison.
Claim 7
Dependent Claim
22 words
A module (7) as claimed in claim 4, wherein said response means includes means for running a program stored in said module.
Claim 8
Dependent Claim
43 words
A module (7) as claimed in any one of claims 4 to 7, wherein each memory location (22) is associated with a simple, short code, and includes means responsive to the entry of each code to retrieve data from the associated memory location.
Claim 9
Dependent Claim
41 words
A module (7) as claimed in any one of claims 4 to 8, wherein the or each message, request for information and instruction transmitted is in a specific format, and the module (7) includes means (16) for recognising the specific format.
Claim 10
Dependent Claim
38 words
A module (7) as claimed in any one of claims 4 to 9, including means (27,28) for rendering any or all of said fixed memory locations accessible or inaccessible from either the subscriber unit or the host station.
Claim 11
Dependent Claim
24 words
A module (7) as claimed in any one of claims 4 to 10, including a directory structure (21) within which files can be stored.
Claim 12
Dependent Claim
25 words
A module (7) as claimed in any one of claims 4 to 11, wherein the module is in the form of an integrated circuit card.
