This invention relates to a software downloading device for telecommunications terminal, such as mobile radiophone for cellular network, cordless phone or fixed terminal in an integrated services digital network. These terminals have some characteristics in common: microprocessor which performs the main functions required for their operation.
The software program executed by each of these terminals must be able to evolve with time in order to: either correct software anomalies, improve the terminal operation, provide new services to subscribers, follow the changes made to telecommunication network technical specifications, or be matched to various networks where different software programs need to be executed, when a terminal is moved to another Scountry for instance.
Significant difficulties are encountered when changing the software program cx- 0ecuted by a terminal. The software is typically stored in a ROM. To change a software program it is necessary to return the terminals to a Company branch for replacement of some of the terminal's components. Therefore, each terminal is unavailable to the user for a certain period of time. These operations are therefore costly to the network operator. The purpose of the invention is to propose a device eliminating these drawbacks.
15 In accordance with the invention, a software downloading device for tclccom- 0 munication terminal connected to a telecommunication network via a conventional interface, called network connection interface, the said terminal being fitted with a microprocessor which controls the operation of the said terminal by executing a software program, called operating software, is characterised in that it is fitted with: program to a RAM.
The device thus featured makes it possible to change the operating software of a telecommunication terminal, each time new software is required for the reasons listed above. Device and downloading costs are minimal, it is therefore possible to use it for terminals sold in very large quantities.
Preferably, the downloading interface is made up of the conventional interface connecting the terminal to the telecommunication network, the software to be downloaded being forwarded by the said network via the conventional interface.
The device thus featured has the advantage of being quite s;mple, since there is no need to add another interface.
Preferably, the downloading interface is made up of an interface dedicated to downloading, the software to be downloaded being forwarded by means other than the conventional means used to forward information to the terminal. The device thus featured has the advantage of providing for software downloading entirely independent from the telecommunication network to which the terminal is usually connected, this eliminates any constraint imposed by the latter, such as limitation of the flow of information transmitted for downloading, or occupancy of a network transmission channel during all the time required for software downloading.
Preferably, the device includes several RAMs, and is fitted with some means of write-selecting one of these RAMs, to download a different software program in each of these RAMs, and read-selecting one of these RAMs, to execute one of these software programs in the microprocessor.
The device thus featured makes it possible to change the operating software without having to download each time. Matching a radiophone or cordless phone to 1• a network change is therefore simplified. Matching consists only of selecting one of the memories, if the software corresponding to the area in which the terminal is located had already been downloaded.
In order that the invention may be readily carried into effect, embodiments thereof will now be described in relation to the accompanying drawings, in which: Figures 1 to 3 respectively represent the block diagrams of three examples of 15 radiophone, respectively including three examples of implementation of the device in accordance with the invention.
Figures 4 and 5 respectively represent the block diagrams of two examples of fixed terminals in an integrated services digital network, respectively including two examples of implementation of the device in accordance with the invention.
Radiophone shown in Figure 1 is fitted with: a first RAM a second RAM a ROM storing the downloading software, a microprocessor and a radio o 20 interface All these devices are interconnected via a bus. Radiophone is linked by radio to a base station connected to a radiotelephone network Radio interface is a conventional interface enabling the radiophone to communicate with base station but it is also used to download an operating software program into one of the two RAMS and Downloading operations are performed by microprocessor by executing the downloading software stored in ROM Since iwo RAMs (I and 2) are available, it is possible to store two different software programs which may, for instance, :'nrrcspond to the current applicable software and to another which will replace the previous one at a set date. Or the two 4 software programs correspond to two different network types, operating in different countries.
Of course, this example is not limiting, as it is possible to provide for a larger number of RAMs if more than two different software programs need to be used due to network variety.
Radiophone being fitted with several RAMs (1 and some means are provided to write-select one of these RAMs in order to download a different software program in each of them, other means are provided to read-select one of the se RAMs in order to run only one of the software programs.
The means used to write-select one of these RAMs consist mainly of a microprocessor controlled either by: the downloading software stored in ROM or by a module provided in each operating software.
When no operating software is loaded in the RAMs, write-select is controlled by microprocessor in accordance with the downloading software instructions. Furthermore, the downloading software supplies some instructions to allow the radiophone to set-up a radio link, hen download a software program via this link.
The downloading software program is called into execution either by a message supplied by network or by a user's command entered from the keypad integrated 15 to the radiophone not shown.
Selection of the software to be run for norm;:! operation, ie. read-selection of one of the two RAMs, is controlled either by a message sent by network or by a command issued by the user.
Each operating software includes a module to acknowledge: a message from network or a user's command, and the identity of the software eventually stored in RAMs and in order to determine which RAM must be read or write selected.
The radio interface, defined by the Group Special Mobile of the Conference Europeenne des Telecommunications, provides for data transmission channels between the network and mobile :,adiophones for a point-to-point transmission or general broadcast. These chnnels admit a bit rate of up to 9.6 kbits per second.
General broadcast can be used to simultaneously update the software in an entire fleet of radiophones. Conversely, point-to-point transmission can be used to download in a specific radiophone entering an area serviced by a network requiring execution of an operating software not yet store'l ir, one of the radiophone RAMs.
Downloading is started upon the initiative of the network, after analysis of a parameter, called "Classmark Update", contained in a message, called "Loc Upd Request", sent by the mobile radiophone to initialise a localisation procedure when it enters a new zone. This parameter indicates the radiophone version. It also indicates whether this radiophone is downloadable and which type of downloading it is likely to accept: partial, for certain functions, or total, for all functions except localisation and downloading. Network starts downloading by sending to radiophone a radio message interpreted by microprocessor by executing the ppropriate module of the operating software which is being executed at the moment under consideration.
Once downloading is completed, the localisation procedure is finished. The radiophone is then in possession of all the information required to operate in the new zone.
S, 10 Downloading software production is within the capabilities of the man skilled in the art. The section designed to download to the RAMs is similar to the bootstrap software used to load a software diskette into the main memory of a computer. The section designed to set-up a radio link is a simplified version of a conventional software controlling the operation of a radiophone.
This first variant of a device in accordance with the invention has the advantage 15 of being simple and inexpensive, since the radiophone needs only be fitted with at least one RAM and one ROM storing the downloading software, without additional interface with regard to a conventional radiophone. Several terminals can be down- S loaded simultaneously, allowing part ,r all of the terminals in the radiotelephone network to be updated in a single operation. It is therefore easy to distribute software upgrades or to entirely replace the software.
Figure 2 represents the block diagram of radiophone (10) fitted with a second example of implementation of the device in accordance with the invention.
Radiophone (10) is fitted with: two RAMs (11) and a ROM (13) storing the downloading software, a microprocessor a standard radio interface a smart card reader interface and a smart card reader Devices I) and (16) are interconnected via a bus.
The downloading interface is a dedicated interface, inr,!pendent of radio interface and made up of smart card reader interface With this variant it is possible to download the software independently from the radiotelephone network, which offers the advantage of not being subjected to network constraints. Moreover, software downloaded by card is simpler than software downloaded by radio link, 6 since radio link set up involves a complex procedure. Downloading is user-controlled via a keypad integrated to radiophone the user must first insert a smart card (18) in smart card reader Write-selection of one of the two RAMs (11 or 12) is user-controlled from the keypad. Read-selection of one of the two RAMs is controlled either by the user, or by a module of the operating software, currently being executed, as described above for radiophone when entering a new zone for instance.
It is possible to produce a downloading software whereby software can be alternately downloaded by radio interface as described for radiophone or by smart card reader (17) as described above for radiophone The smart card (18) is sent to the users by the network operator, either by mail or via a distribution network such as company branches, or ordinary shops. It should i 10 be noted that the smart card reader can be replaced with a magnetic card reader.
Figure 3 represents the block diagram of radiophone (20) including a third example of implementation of the device in accordance with the invention. It is fitted o* with: two RAMs (21 and 22), one memory (23) storing the downloading software, one microprocessor one standard radio interface (25) and one interface (26) for connection to a standard port of the ISDN network Radiophone (20) sets up a 15 radio link with a base station connected to radiotelephone network The latter is connected to the ISDN network Devices (21) to (26) are interconnected via a bus. Radio interface (25) can set up a radio link with base station (59) for telephone signal transmission, but software downloading is carried out via a cable temporarily connecting interface (26) to a standard port of network This cable is fitted with a standard jack (27) which can be plugged into a standard socket (28) connected '1o network (57).
When the user wants to download the software in radiophone he first plugs in the cable connecting interface (26) to network then he write-selects one of the two RAMs (21 or 22) via the keypad. Read-selection of one of the two RAMs (21 or 22) is carried out similarly to that described for radiophone This variant has the advantage of using a software transmission device more easily available than a smart card, in so far as the number of network (57) ports is very high.
Figure 4 represents a block diagram of a fixed terminal (30) for ISDN network, this terminal (30) including a fourth example of implementation of the device in accordance with the invention. Terminal (30) is fitted with two RAMs (31 and 32) to respectively store two different operating software programs, written via downloading, one ROM (33) for permanent storage of the downloading software, one microprocessor and one ISDN network connection interface (35) which is also an operating software downloading interface.
Interface (35) is permanently connected to a standard port of ISDN network (38) via a cable fitted with a standard jack (36) plugged into a standard socket connected to network The advantage of this variant is that the operating software is downloaded via a conventional interface hence, there is no need to add a dedicated inte face.
Each standard port (37) includes a channel called user to user signalling channel, and several channels for the actual transmission, forwarding voice signals for instance. Software downloading can occur via any one of these two types of channels, or by combining both. The transmission channel being used to transmit the software to be downloaded, and the signalling channel being used to initialise and end downloading.
Downloading to one of the RAMs (31 or 32) is initiated either by the user via a keypad, or by the operating software being executed, when it receives the download command from network Each operating software program includes a module 15 to acknowledge: a user's command or a network (38) command. Read or writeselection of one of these two RAMs is controlled by microprocessor in accordance with the instructions from the downloading software and the commands issued either y the uscr or the network.
Downloading a new oprating software or switching from an old software to a new one can be totally remote-controlled by the network (38) operator, without user intervention.
0 Figure 5 represents the block diagram of another example of fixed terminal for ISDN network this terminal being fitted with a downloading device in accordance with the second variant. Terminal (40) is fitted with: two RAMs (41 and 42) to respectively store two different operating software programs which arc downloaded, one ROM (43) for permanent storage of the downloading software, one microprocessor one ISDN connection interface one smart card reader interface and one smart card reader Devices (41) to (46) are interconnected via a bus.
Interface (45) is a conventional interface permanently connected to the ISDN network (51) via a cable fitted with a standard jack (49) plugged into a socket connected to network Smart card reader (47) is connected to the input of interface To download the operating software, the user selects one of the two RAMs (41 or 42) via a keypad, not shown, then inserts a smart card (48) into reader Read-selection of one of the two RAMs is carried similarly to that described before for terminal It is possible to design a downloading software whereby downloading may occur alternately via network (51) or card depending on the circumstances. Reader (47) may be replaced with a magnetic card reader.
The scope of the invention is not limited to the examples described above. It can be applied to any other telecommunications terminal fitted with a microprocessor, in so far as the complexity of its software and its evolution in time justify that this software be changed occasionally.
