Description

The present invention relates to a method of setting a list of accessible processing devices from a processing controller.

It concerns correlatively a device adapted to implement the method of delivery to the invention.

It relates generally to the field of computer communication networks, and more particularly the development of wireless networks without being however limited to this type of network.

In the computer communication networks are connected a plurality of processing control devices and processing peripherals.

The process control devices make it possible to initiate the processing of a document by a processing device. These processing control devices typically include computers or for example a cordless phone.

Processing devices include both printing devices of a document, such as a printer or an electronic whiteboard associated with a printer and printing devices. transmission of a document, such as a fax machine, a modem and generally any type of communication interfaces to the outside of the communication network considered. These processing devices can also be devices for acquiring a document, such as a scanner, or possibly document storage devices.

Conventionally, these devices are connected to the network or by being connected via a interface card <B> to a computer itself connected to the network, while being connected directly to the communication network. In the latter case, the use of the processing devices is in fact shared by all users connected by means of a network processing controller.

Increasingly, these devices are made accessible to a user's wireless processing control device. <B> It </ B> is no longer necessary to be connected by a cable to be able for example to print or transmit a document. These processes may possibly even be implemented even though the process control device is moving within the wireless communication network or between several wireless communication networks.

In general, when the user moves within a wired network, or when he moves between several communication networks, whether wired or not, he will have to use a processing device, such as For example, a printer may need to perform many prerequisites to print the document. <B> It </ B> will first need to search for locally available printers, then download the printer driver from the printer. the mobile processing controller, install this driver, and then possibly modify the configuration of this driver according to the flow available on the communication network.

All these operations are long and not accessible <B> to </ B> a typical user of a communication network.

Similarly, the processing devices can be mobile within a network or between several communication networks. The day-to-day update operations described above must then be repeated when certain processing devices have been moved, added, or deleted on the communication network. It is an object of the present invention to overcome the aforementioned drawbacks and to provide a method for automatically setting <B> to </ B> the accessible process devices <B> to </ B> from a processing controller .

According to the invention, the method of setting a list of accessible processing devices from a controller method of processing within a computer communication network connecting said processing peripherals to the processing controller, comprises the following steps: <B> - </ B> motion detection of said controller processing device or processing device within one or more computer communication networks; <B> <B> - </ B> <B> - </ B> <B> - </ B> for processing control <B>; </ B> <B> - </ B> extraction of new processing devices by comparing the listed process devices with the list of accessible process devices <B> to </ b> of the processing controller <B>; </ B> <B> - </ B> driver installation of the new peripherals if this driver is not installed <B>; </ B> and <B> - <B> adding to </ B> the list of accessible processing devices <B> to </ B> from said processing control device of the new processing peripherals.

The method of setting <B> to </ B> day according to <B> to </ B> the invention thus makes it possible, as soon as the movement of the mobile treatment control device or a mobile processing device is detected, to discover and install the processing peripherals located near the processing controller in the communication network.

This system is transparent to the user who no longer needs to configure their processing controller to process a document when it is in a new location, connected to a new communication network . According to a preferred feature of the invention, the method of setting <B> to </ B> day further comprises a step of selecting a default processing device in said list of accessible process devices <B> to < / B> from said processing controller.

This selection step allows to assign to the processing controller a default processing device including <B> to </ B> each new location of this processing controller so that its operation is similar <B> at </ B> a fixed processing controller for the user.

In practice, at the selection step, a processing device is selected having configurability characteristics similar to the configurability characteristics of a previously selected default processing device.

There is thus a processing device compatible with the one previously chosen for the processing control device so that the processing of a document, for example its printing can be performed in a very similar way regardless of the location of this device. treatment control.

According to a preferred feature of the invention, the method of setting <B> to </ B> day further comprises a step of displaying the list of accessible processing devices <B> to </ B> from said device. treatment control.

The user can thus simply view all the devices that are accessible at a given location of the processing controller in the communication network, at a given moment.

Preferably, at the display step, the processing devices listed at the enumeration step are displayed, and the other devices in said list of processing devices are hidden.

This feature allows the display to be limited to the peripherals located at the immediate vicinity of the processing controller in the communication network and to temporarily mask the devices that are remote from the processing controller, ie the location of the latter has changed, or that processing devices have been moved.

These masked process devices, however, are stored in the device list so that they can very simply be available again when the process control device or the processing devices within the network is moved later. between several communication networks.

According to one embodiment of the invention, at the detection step, the detection of the motion of said treatment control device or processing device is performed when said treatment control device or peripheral device. processing is registered with a new base station in a wireless computer communication network.

Detection of the movement of the treatment controller or processing device in a network or between wireless networks is very simple, at the same time as the recording of this processing controller or device mobile processing on the network.

In another embodiment, particularly well suited to the wired network, to the detection step, detecting the movement of said treatment control device or processing device is performed by detecting a change. network address of said processing controller or processing device connected in a wired computer communication network.

According to a particularly preferred embodiment of the invention, the method for bringing the invention into conformity with the present invention also comprises the following steps: ## EQU1 ## B> evaluation of the available bandwidth on the computer communication network <B>; </ B> </ b> - </ b> - choice of a mode of configuration of said processing devices identified according to said available bandwidth < B>; </ B> and <B> - </ B> to <B> to </ B> day if necessary of the configuration of the aforementioned processing devices <B> to </ B> from the selected configuration mode . This results in a day-to-date process that automatically changes the characteristics of the processing devices as perceived by the user to make them compatible with the available bandwidth on the communication network.

The configuration of the processing devices can thus be changed when the flow varies.

This possibility is particularly interesting in wireless communication networks which, by nature, do not allow to ensure a constant flow. Interference often occurs, which causes errors in the transmission of data packets over the network and thus reduces the available bandwidth. This is the case for example when a user who wants to print a large document, has to wait an excessive time before the print is completed completely.

By automatically adjusting the configuration of the <B> processing devices to the available bandwidth on the network, documents can be processed in a reasonable amount of time for the user.

According to an advantageous characteristic of this embodiment of the invention, the method of setting <B> to </ B> day further comprises a step of displaying the list of accessible processing devices <B> to </ B > from said adapted processing control device <B> to </ B> display the selected configuration mode respectively for said identified processing devices.

This display step is used to indicate to the user if the accessible devices can be used in a full mode or in a degraded mode (for example with a lower processing resolution) depending on the configuration chosen. depending on the bandwidth available on the communication network.

Preferably, in order to allocate to the processing controller a compatible default processing device despite the possible modification of the configuration of the processing devices as a function of the available bandwidth, the method of setting <B> to </ B day further includes a step of selecting a default processing device in said list of processing devices accessible from said process controller to select a processing device having a mode of operation. selected configuration similar to the configuration mode of a previously selected default processing device.

Conveniently, the selection step is adapted to choose a configuration mode by means of a configuration table associating a configuration mode to a bandwidth value available.

According to an advantageous version of the invention, the step of evaluating available bandwidth is periodically implemented in order to regularly detect the bandwidth changes that may influence and in particular delay the processing of a document.

In practice, <B> at </ B> the evaluation step, we calculate a value of average bandwidth <B> to </ B> from successive evaluations of bandwidth instantaneous value of the computer communication network .

Preferably, the evaluation step comprises the following substeps <B>: - </ B> assessment of the instantaneous value of bandwidth <B> - </ B> comparison of said instantaneous value <B> to < / B> an average bandwidth value <B>; </ B> <B> - </ B> reiteration of the evaluation and comparison steps if the difference between said instantaneous value and said average value is greater <B> to </ B> a predetermined threshold value <B>; </ B> and <B> - </ B> deduction of a non-temporary change in bandwidth when the difference between said instantaneous value and said average value of bandwidth is greater than the predetermined threshold value for a predetermined number of successive evaluations of the instantaneous bandwidth value.

This succession of steps makes it possible to take into account a bandwidth change only when it is not temporary. This ensures that the chosen configuration mode is well suited to the bandwidth actually available on the network and does not correspond to a limited reduction in the available bandwidth. which would no longer be used when processing the document. Thus, in practice, the steps of choosing a configuration mode and setting <B> to </ B> day if necessary of said configuration are reiterated when at the deduction step, a non-temporary change in bandwidth is deducted. The day-to-day delivery method of the invention is particularly well suited when the processing devices are printing devices of a document, such as a printer. or an electronic whiteboard, and / or document transmission devices, such as a fax machine or a modem, and / or document acquisition devices, such as a scanner.

Correlatively, the present invention also relates to a device for setting <B> to </ B> day of a list of accessible processing devices <B> to </ B> from a processing controller within a computer communication network connecting said processing peripherals to the process controller, comprising: motion detection means of said process control device or a motion detection device; processing device within one or more computer communication networks <B>; </ B> <B> - </ B> means for enumerating the processing peripherals <B> at </ B> proximity of said device process control <B>; </ B> <B> - </ B> means for retrieving new processing devices by comparing the identified process devices with the list of accessible process devices <B> to < / B> from said treatment controller <B>; </ B> <B> - </ B> driver installation means new processing devices if said driver is not installed <B>; </ B> and <B> - </ B> means of adding <B> to </ B> said list of processing devices accessible from said control device for processing new processing peripherals.

Referring first to <B> to </ B> 1, </ B>, communication networks <B> 1, </ B> 2 adapted <B> to </ B will be described. > implement the invention. A first <B> 1 </ B> network has multiple <B> 11, </ B> 12, and <B> 13 </ B> computers interconnected by a wired <B> 3 </ B> network. particular, for example by an ethernet network.

Processing devices of different types can be connected to these computers to implement different types of processing of a file: for example, a printer 14 is connected to <B>. > to </ B> a first computer <B> 11, </ B> a modem <B> 15 </ B> and a scanner <B> 16 </ B> are connected <B> to </ B> a second computer 12 and a fax machine <B> 17 </ B> is connected <B> to a third computer <B> 13. </ B>

These processing devices 14, <B> 15, 16, 17 </ B> are connected to the computers by specific connections of appropriate and usual types in the wired computer networks <B>: for example, serial, parallel or SCSI (English Small Computer Simple Interface).

Of course, in this type of wired communication network, processing devices could also be directly connected to the communication network <B> 3, </ B> without the intermediary of a computer.

A second network 2 is also adapted to implement the invention. This is a wireless communication network, the computers and peripherals of the network communicating with each other. between them by radio links.

This second network thus comprises in this example two computers 21, 22 and a printer <B> 23 </ B> each having a communication port <B> A, <B> C </ B> consisting of an antenna adapted to receive and transmit radio waves.

In addition, the computers 21, 22 are connected as previously, by usual connections in the wired networks, <B> to </ B> printers 24, <B> 25. </ B>

Throughout the following description, we will consider <B> to </ B> as an example that the processing devices are suitable printers <B> to </ B> print a document.

Of course, the processing peripherals may be printing devices of a document, such as a printer 14, 23, 24, 25, or an electronic whiteboard. , or document transmission devices, such as a fax <B> 17 </ B> or a modem <B> 15, </ B> or document acquisition devices, such as a scanner <B> 16. </ B>

It will also be considered that the processing control device <B> from </ B> from which the processing is initiated, here the printing of the document, is a computer <B> 10. </ B>

In this example, this computer <B> 10 </ B> is mobile within the wireless network 2 or between the communication networks <B> 1, </ B> 2.

However, the method of setting <B> to </ B> day described below could also be implemented similarly in the case where a processing device, such as a printer for example, is mobile in the wireless network 2 or is moved from one <B> communication network to </ B> the other.

<B> A </ B> As an example, the <B> 10 </ B> mobile computer can be connected to the first <B> 1 </ B> network so that a document stored on that computer mobile <B> 10 </ B> can be processed by one of the 14, <B> 15, 16, 17 network devices <B> 1. </ B>

This mobile computer can be moved, for example when the user changes location, and be connected by means of a radio antenna <B> C </ B> to the second network 2.

Depending on its location in this wireless communication network 2, the anchoring of this mobile computer <B> 10 </ B> in the network 2 will be done by one of the communication ports <B> A, </ B> B <B> C. </ B>

 Optionally, the mobile computer <B> 10 </ B> can be moved within the wireless communication network 2 so that its anchor point is changed.

According to its anchor point in the communication network 2, the processing peripherals closest to the mobile computer <B> 10 </ B> will be modified.

In a first embodiment of the invention, a method as illustrated in Figure 2 allows a list of accessible process devices to be set to <B> at a later date. <B> to </ B> from the mobile computer <B> 10, either that it moves within the wireless network 2, or that it moves between different communication networks <B> 1 , </ B> 2. This method of setting <B> to </ B> day involves firstly a step <B> El </ B> detection of the movement of the mobile computer <B> 10. < / B>

Depending on the type of communication network to which the mobile computer <B> 10 is connected, </ B> this motion detection step can be implemented differently.

As illustrated <B> at <B> 3, </ B> in a wireless communication network 2, when the computer <B> 10 </ B> is started, a search step Ell of a base station <B> A, <B> C </ B> is implemented then the computer <B> 10 </ B> comes to register with this station in a registration step <B> E12. </ B>

A test step <B> E13 </ B> makes it possible to compare this new anchor point with the preceding anchor point and to deduce respectively in detection steps E14 and <B> E15, </ B> that it <b> y </ B> actually had mobile computer <B> 10 </ B> motion when the anchor points are different and vice versa, that there was no movement of the mobile computer <B> 10 </ B> when the anchor points are the same.

It is thus understood that it effectively detects a movement of the computer when the latter actually changes the anchor point in the wireless communication network 2 and registers with it. a new base station. A simple movement of the computer that is not sufficient to change its anchor point is not a movement within the meaning of this motion detection step <B> El. </ B>

Moreover, the set of detection steps <B> El 1 to El 5 </ B> can be implemented periodically, for example every fifteen minutes, to check if the mobile computer has not been moved in the wireless communication network 2.

As illustrated in Figure 4, when the communication network is a wired network, detecting the movement of the computer from one wired network to another wired network can be done in practice after a startup step <B> E20 </ B> of the mobile computer <B> 10, </ B> by detecting a defined IP network address change (in English Internet Protocol) on <B> 32 </ B> bits according to the Internet protocol. In a step <B> E21 </ B> the previous network address IP1 is read, the new IP2 address is acquired in a step <B> E22, </ B> and a comparison step <B> E23 </ B> compare these IP1 and IP2 addresses.

According to their identity or not, we deduce respectively in steps E24 and <B> E25 </ B> that <b> y </ B> had a movement of the computer <B> 10 </ B> or not.

As previously stated, this detection of a movement on the networks could also be implemented for the processing peripherals.

Returning <B> to </ B> in Figure 2, if <B> to </ B> the motion detection step <B> El, </ B> no movement of the mobile computer <B> 10 </ B> has not been detected, the process of setting <B> to </ B> day ends.

On the other hand, if the mobile computer has just registered on a new base station of a wireless network or has been physically connected to another network, a census step <B> E2 </ B> can search local printers, located <B> at </ B> near the computer <B> 10. </ B>

A single computer request can be sent <B> to </ B> from the mobile computer <B> 10 </ B> across the entire communications network so that local printers respond and identify with the computer. mobile computer. The use of such a broadcast search is well known in the field of computer communication networks and does not need to be detailed further here.

In practice, for example in the wireless communication network 2, the printers near an anchor point of the mobile computer <B> 10 </ B> may be the printers that are on the same subnet.

An extraction step <B> E3 </ B> of new printers is then implemented by comparing the registered printers with the list of accessible printers <B> to </ B> from the computer that needs to be set <B> to </ B> day.

If there are new printers, not yet listed in the printer list, an E4 test step is used to check if the printer driver is <B> already installed <B> on the mobile computer <B > 10. </ B>

If it is <B> already </ B> done, an installation step <B> E5 </ B> will perform this installation. The <B> to </ B> distance installation of a printer is well known in the state of the art and is described for example in US Patent <B> US 5,692,111. </ B> In summary, From a remote computer to which the printer is connected is obtained the list of files that comprise the driver of the printer. These files are downloaded to the mobile computer <B> 10 </ B> and then the printer is installed locally. In practice, we add a printer to create a local printer and we associate the driver files <B> to this new printer.

Whether or not there are new printers, whether they are <B> already installed or not, then the <B> to </ B> day process has a <B> upgrade step to </ B> day <B> E6 </ B> of the list of accessible printers.

Notably, during this step of setting <B> to </ B> day <B> E6, <B> is added to </ B> this list the new printers listed <B> to </ B> the census step <B> E3. </ B>

It may be possible, although not necessary, to remove from this list printers that are no longer located <B> at </ B> near the mobile computer <B> 10 </ B> and that do not have not recorded. However, it is wise to keep the printers in this list for later moving of the <B> 10 </ B> mobile computer, after which these printers could be located <B> again at </ B> close to the mobile computer <B> 10. </ B>

Preferably, the method of setting <B> to </ B> day further comprises a step of displaying <B> E9 </ B> of the list of accessible printers <B> to </ B> from the mobile computer <B> 10. </ B>

The <B> to </ B> day update of the list of printers then results in the display of this list, displaying the printers listed <B> at </ B> the census step <B> E2, < / B> by means of a specific icon for each of the printers, and by hiding the other printers in the list.

For example, printers that are no longer in the immediate vicinity of the <b> 10 </ B> mobile computer can be temporarily hidden.

In a preferred embodiment, a selection step <B> E7 </ B> of a default printer in the list of accessible printers set <B> to </ B> day is implemented. This default printer should of course be located <B> to </ B> near the mobile computer <B> 10 </ B> and be part of the printer list set <B> to </ B> <B> at <B> step E6 </ B> previously described.

Preferably, <B> at </ B> this selection step <B> E7, </ B> a printer having configurability characteristics similar to the configurability characteristics of a previously chosen default printer is selected prior to moving of the mobile computer <B> 10. </ B>

A printer compatible with the one previously used is thus chosen. By compatible printer is meant a printer having similar characteristics, for example in terms of color printing, usable paper sizes, possibility of printing on both sides, with stapling, etc.

Once this default printer is selected, a <B> to </ B> day <B> E9 </ B> step will assign this selected printer as the default printer <B> to </ B>. mobile computer <B> 10. </ B> In practice, the display step <B> E9 </ B> can be used to display this default printer, for example by identifying an icon different from those used for other local printers.

This process of setting the list of accessible printers in the day to day allows, in a completely transparent way for the user to register the local printers and to install them on the computer whatever the communication network to which the mobile computer <B> 10 is connected. </ B>

In a second embodiment of the invention, a method as illustrated <B> to </ B> Figure <B> 5 </ B> allows to set <B> to </ B> day characteristics of Configure at least one accessible printer from <10> based on the available bandwidth on the network to which the <B> 10 computer is connected. </ B>

This method of setting <B> to </ B> day of the printer configuration can be implemented in conjunction with the process of setting <B> to </ B> day of the list of accessible printers <B> to < / B> from the mobile computer <B> 10, </ B> especially when it is connected or moves within a wireless communication network 2. The method of setting <B> to </ B> day of the configuration of accessible printers can also be implemented separately from the method described above, for example in a wireless network in which the available bandwidth is likely to vary over time due to interference on the links radio. In this case, this method of setting <B> to </ B> day of configurations is completely independent of whether the <B> 10 </ B> computer has moved or not and applies as well <B> to </ B> a mobile computer <B> 10 </ B> than to a stationary computer.

This method of setting up configurations starts with a step of evaluating the bandwidth available on the computer communication network to which the computer is connected. .

A choice step <B> E33 </ B> then allows you to choose a configuration mode according to the bandwidth available on the network.

This selection step is implemented for all accessible printers <B> to </ B> from the computer <B> 10. </ B>

When this method of setting day-to-day configurations is implemented in conjunction with the day-to-day process of a list of accessible printers <B> to </ B> > from a mobile computer <B> 10, </ B> this selection step is implemented for all the printers in the list set <B> to </ B> day, that is to say say for printers listed <B> at </ B> the census step <B> E2. </ B>

In the case of a stationary computer, a list of accessible printers is also associated with the computer.

A selection step <B> E32 </ B> is used to select a first accessible printer.

The choice of <B> E33 </ B> is then chosen by choosing a configuration mode of this printer according to the available bandwidth in order to make the operation of the printer compatible with the bandwidth available.

This configuration mode is preferably chosen by means of a configuration table which associates, for each printer of the network, a configuration mode <B> at </ B> a value or an interval of available bandwidths. Typically, the smaller the bandwidth available, the more the configuration mode will be degraded. This can reduce the print resolution factor or the number of color shades used by the printer to speed up the processing of the <B> to </ B> print document.

A step of setting <B> to </ B> day E34 <B> - E37 </ B> is then implemented to modify if necessary the configuration of this first printer <B> to </ B> from the mode chosen configuration.

In practice, a read step E34 reads the current configuration of the printer.

We verify in a comparison step <B> E35 </ B> whether the current configuration and the chosen configuration are identical or not.

If so, repeat steps <B> E33 to E37 </ B> for the next printer in the list of accessible printers <B> to </ B> from the computer.

Otherwise, an actual <B> to </ B> day <B> E36 </ B> step is used to apply the chosen configuration mode <B> to the first printer.

Preferably, when a display step <B> E9 </ B> as described above is implemented to display the list of accessible printers <B> to </ B> from the computer, it is adapted <B> to </ B> view the chosen configuration mode respectively for each printer.

A step of setting <B> to </ B> day of the display <B> E37 </ B> thus makes it possible to modify the display according to the mode of configuration applied <B> to </ B> each printer. For example, when each printer is represented by an icon, the latter is for example in solid lines when the printer is in a configuration mode that allows printing in satisfactory conditions (without degradation of the optimal configuration mode, or time of wait too long) depending on the available bandwidth, and greyed out, when the printer is usable but in a degraded configuration mode.

We check in a test step <B> E38 </ B> if the printer is the last printer in the list of accessible printers <B> to </ B> from the computer, and if not, we selects in a selection step <B> E39 </ B> a next printer and repeats the steps of choice and setting <B> to </ B> day of the configuration mode previously described. Preferably, the method of setting up configurations also comprises a step E40 selection of a default printer in the list of accessible printers <B> to </ B> from the 'computer.

A printer having a chosen configuration mode similar to the configuration mode of the current default printer, i.e. the default printer selected so far for the computer, is selected.

A reading step E41 makes it possible to know this current default printer and a comparison step E42 makes it possible to check whether the selected printer and the current printer are different.

If so, the user is notified of the default printer change either by a specific message, or directly by changing the display of the list of accessible printers to make the new default printer visible to a specific icon.

An upgrade step <B> to </ B> day E44 allows you to assign this new selected printer <B> to the computer as the default printer.

<B> It is a good idea, even when the computer is stationary, that the available bandwidth evaluation stage <B> E30 </ b> is implemented periodically, especially in wireless communication in which the bandwidth and associated rate are likely to be frequently changed due to interference to detect changes in available bandwidth.

In practice, <B> at </ B> the evaluation step <B> E30, we calculate an average bandwidth value BPm <B> at </ B> from successive value evaluations instant bandwidth of the computer communication network.

This average over the time of the available bandwidth makes it possible to have a better estimate of the real value of the available bandwidth of the network and to differentiate the permanent available bandwidth changes from the simple transient or punctual changes in time and which do not require to change the configuration of the printers.

<B> A </ B> This effect, the evaluation step is detailed <B> to </ B> Figure 6. </ B> An initialization step <B> E50 </ B > allows to initialize a variable Change <B> to </ B> the answer "no".

A step <B> E51 </ B> is also used to initialize a counter whose function is explained below. This counter corresponds to the number of measurements that are performed before deducing that the available bandwidth has changed permanently.

The evaluation step then comprises an evaluation step <B> E52 </ B> of the instantaneous value BPi of bandwidth. This evaluation step <B> E52 </ B> corresponds to the <B> reading of statistics of a radio equipment associated with <B> to </ B> the computer. This reading can be done via an SNMP (Simple Network Management Protocol).

<B> A </ B> as an example, with reference <B> to </ B> Figure 1, </ B> in Wireless Communication Network 2, when the computer <B> 10 </ B> is attached to the anchor point <B> A, </ B> the information collected will relate to the radio link between this mobile computer <B> 10 </ B> and the anchor point <B> A </ B> and the segment of the wired network connecting the printer <B> 25 </ B> to the anchor point <B> A </ B> via the computer 22.

<B> A </ B> As an example, this can be the number of bytes that have been transmitted during the duration of a SNMP-enabled link quality test.

Alternatively, this information may also be the estimation by the associated radio module <B> to </ B> the computer <B> 10 </ B> of the received signal power. The result of the reading step <B> E52 </ B> is then stored in a storage step <B> E53, </ b> then the instantaneous bandwidth BPi is calculated in a calculation step E54.

This calculation can be performed by simply dividing the number of bits transmitted by the transmission duration, or by using a pre-established conversion table which associates <B> with </ B> a received power with an available bandwidth value.

A comparison step <B> E55 </ B> then makes it possible to compare the instantaneous value BPi <B> with the average bandwidth value BPm and to calculate the difference <B> A </ B> between these values. two values. A comparison step <B> E56 </ B> is performed to check whether this difference, in absolute value, <B> I AI </ B> is greater than a threshold value predetermined T.

We can set a threshold T corresponding for example <B> to </ B> a rate of 10%.

If this difference between the instantaneous value BPi and the average value BPm is lower than this threshold value T, it is deduced that there is no change in the bandwidth.

Conversely, if this difference <B> A </ B> is greater than the threshold value T, the counter value of one unit is incremented in a step E47 and this updated value of counter <B> to </ B> a prefixed maximum value <B> C </ B>.

If the value of the counter is less than this maximum value C, the evaluation steps E52-E54 and comparison E55-E56 are repeated.

When the value of the counter reaches this value <B> C, that is to say that the difference between the instantaneous value BPi and the average value BPm of bandwidth remains higher <B> than </ B> the predetermined threshold value T during a predetermined number <B> C </ B> of successive evaluations of the instantaneous bandwidth value, it is deduced in a step <B> E59, </ B> that a change of temporary bandwidth availability occurred on the communication network 2.

The answer "yes" is then associated <B> with the </ B> variable Change and the set of steps described above with reference <B> to </ B> the figure <B> 5 </ B> can be put in use to change the configuration mode of printers in the communication network.

Thus, the steps of choosing a configuration mode and setting <B> to </ B> day if necessary of this configuration are reiterated only when a non-temporary change in bandwidth is deduced.

A calculation step <B> E60 </ B> calculates the new average value of the bandwidth BPm, taking into account instantaneous bandwidth evaluations performed at steps <B> E52 to </ B> E54 and averaging over time these BPi instantaneous values. This average value BPm is stored in a storage step <B> E61 </ B> for later use and a waiting step <B> E62 </ B> is implemented before repeating the steps < B> E50 to E62 </ B> Evaluation of available bandwidth. It is thus possible to set a bandwidth calculation period, for example equal to <B> to 5 </ B> minutes.

This method of setting up configurations enables a real-time adaptation of the configuration of the processing peripherals of a communication network to the bandwidth available on the network. .

With reference <B> to </ B> FIG. 7, a third embodiment of the invention can be implemented for processing a document <B> to </ B> from a computer connected to a printer via a computer communication network according to the bandwidth available on the network.

This document processing method can be implemented jointly or separately from the method of setting up printer configurations described above.

In general, it allows you to degrade the content of the <B> document to </ B> process to fit <B> to the available bandwidth on the network.

As shown in <B> at </ B> Figure <B> 7, </ B> it includes a first step <B> E70 </ B> that checks whether document degradation is allowed.

If not, the process ends and the document is printed without modification.

Otherwise, an evaluation step <B> E71 </ B> of the bandwidth available on the computer communication network is implemented as described above with reference <B> to </ B> Figure <B> 6. </ B> We deduce the average value of the available bandwidth BPm.

A comparison step <B> E72 </ B> is then implemented to compare the available bandwidth BPm with a threshold value BPs. This threshold value corresponds to the minimum bandwidth required to print in good conditions (short waiting time, good quality printing).

If this available bandwidth PBm is greater than the threshold value BPs, the process ends with the printing of the document. Otherwise, a read step <B> E73 </ B> of the document size <B> to </ B> print and a calculation step E74 of a transfer duration <B> D </ B> are set to #uvre.

To read the size of the document <B> to </ B> print, we convert it to numeric data <B> to </ B> print. The size of the document can then be expressed as a number of bits <B> to </ B> print.

In practice, the document, stored as digital data, is converted into a table describing a portion of a monochromatic component of the document, each cell of the table representing a pixel. More precisely, each cell of the table contains the coordinates of a pixel and information representative of the fact that this pixel is "lit" or not. <B> It </ B> therefore exists as many tables as monochromatic components necessary to print the document. Reading and counting these lit pixels from each table is <B> to </ B> the size of the document <B> to </ B> print.

The computation of a transfer duration <B> D </ B> of the document is done according to the size of the document and the available bandwidth.

For example, the transfer time <B> D </ B> is calculated by dividing the number of bits <B> to </ B> print by the rate, expressed in bits per second, associated <B> with </ B > the bandwidth available on the communication network.

A comparison step <B> E75 </ B> compares the transfer time <B> D </ B> with a predetermined acceptable transfer time value <B> D,. </ B> This acceptable value D ,, may have been set at the factory or be determined by learning in order to adapt to the requirements of the user. It may be dependent on the number of pages in the document <B> to </ B> treat or its contents, so that the user can choose a higher threshold value <B> C </ B> for a long document or for a document in color or containing images.

If the calculated duration <B> D </ B> is less than the acceptable duration value D ,,, the processing method ends directly by printing the document.

Note that the total print time of the document is <B> the sum of the transfer time of the document on the network and <B> the </ B> the actual print time, which can vary. from one <B> printer to the other. Otherwise, we check that there is a parameter available in the document that can be degraded.

These available parameters are chosen especially from the number of shades of colors or gray levels used in the document, the resolution factor applied <B> to </ B> the printing of the document and the type of functions <B> to </ B> print included in the document.

Functions, for example, are functions of text, graphic functions, images.

If there is at least one available parameter, a parameter <B> E77 </ B> is selected and degraded in a degradation step <B> E78. </ B>

For example, we reduce the number of shades of colors or gray levels used in the document, we reduce the resolution factor, or we remove some of the functions included in the document from those that are the longest <B> to < / B> print, such as images, then to a lesser extent the graphic functions.

<B> A </ B> the result of this degradation step <B> E78, <B> steps <B> E73 to E75 </ B> are repeated to calculate the new transfer time <B> D </ B> of the document thus degraded.

Degradation steps <B> E77 </ B> and <B> E78 </ B> are repeated as long as the transfer time <B> D </ B> remains higher <B> than </ B> the value of predetermined acceptable transfer time D ,, and that the parameters available for the degradation have not been exhausted.

The processing method then ends with the printing <B> E79 </ B> of the possibly degraded document.

The parameters available for the degradation can be set by the user as well as the order in which they are chosen <B> at <B> the choice step <B> E77 </ B> to perform the degradation.

This processing method thus makes it possible to adapt the processing of a document <B> to the available bandwidth on the communication network, and in particular to avoid too long processing times. We will describe <B> to </ B> present in reference <B> to </ B> the figure <B> 8 </ B> a suitable device <B> to </ B> implement all the previously described methods.

In this embodiment, this device is incorporated in the mobile computer <B> 10. </ B>

This mobile computer <B> 10 </ B> first includes a device for setting <B> to </ B> day of a list of printers <B> 31 </ B> which is illustrated in detail < B> to </ B> the figure <B> 9. </ B>

This setting device <B> to </ B> day includes including means of setting <B> to </ B> day <B> 30 </ B> of the list of printers <B> 31 </ B> which operate with <B> 32 </ B> motion detection means of the computer <B> 10 </ B> within one or more computer communication networks.

These motion detection means <B> 32 </ B> are adapted to detect the movement of the computer when registering with a new computer. base station in a wireless computer communication network 2 or a change of IP network address of the connected computer in a wired computer communication network <B> 1. </ B>

The means of setting <B> to </ B> day <B> 30 </ B> include means of census and extraction <B> 33 </ B> of new printers located <B> to </ B> Proximity to Computer <B> 10 </ B> by Comparing Identified Printers to Accessible Printer List <B> 31. </ B> <B> 33 </ B> allow to send on the network a global request <B> to </ B> all computers and devices connected to the network so that they identify themselves, by their IP network address for example, with the mobile computer <B > 10. </ B>

The setting means <B> to </ B> day <B> 30 </ B> also include means 34 for installing the driver of the new printers and adding means <B> 35 to </ B>. printer list <B> 31 </ B> of new accessible printers.

Display means <B> 36 </ B> is used to display the list of printers <B> 31 </ B> set <B> to </ B> day.

Thus, these display means <B> 36 </ B> are adapted to display the local printers and to hide the other printers in the list 31. </ B>

These display means <B> 36 </ B> are illustrated <B> to </ B>. </ B> 11. </ B> They consist of a classic graphical interface. In this example, two printers rated <B> II </ B> and 12 are available in the current location where the <B> 10 mobile computer is located. </ B>

A directory R also represented by an icon contains the list of printers that were available in places previously visited by the mobile computer <B> 10. </ B> This masking in the directory R avoids that too many d Printers are not visible directly, but still allows the user to use these hidden printers temporarily if necessary in other places.

The setting device <B> to </ B> day of the list <B> 31 </ B> also preferably includes means for setting <B> to </ B> day <B> 37 </ B> d a default printer. These setting means <B> to </ B> day <B> 37 </ B> include means for selecting <B> 38 </ B> from a default printer in the list of accessible printers <B > 31 </ B> which are adapted as previously described to select a printer having configurability characteristics similar to the configurability characteristics of the previously selected default printer.

These setting means <B> to </ B> day of a default printer <B> 37 </ B> also cooperate with the display means <B> 36 </ B> to display on them default printer selected.

In the example in Figure 11, the printer <B> 11 </ B> is the default printer selected, its icon having an extra sign, here an accent, which allows the distinguish from other printer icons.

The mobile computer <B> 10 </ B> further includes a device <B> to </ B> day printer configuration characteristics <B> 31 </ B> which is illustrated in detail <B > to </ B> the figure <B> 10. </ B>

This setting device <B> to </ B> day configurations includes means for setting <B> to </ B> day 40 configurations that operate with means 41 for evaluating the bandwidth available on the network. Communication.

The available bandwidth evaluation means 41 are adapted to evaluate the periodically available bandwidth and to calculate the average bandwidth to be used from time to time. successive evaluations of instantaneous bandwidth value of the computer communication network. These evaluation means operate with a radio module which will be described in detail later.

In general, these evaluation means 41 are adapted to evaluate the instantaneous value of bandwidth BPi, to compare this value. instantaneous <B> to </ B> an average bandwidth value BPm, <B> to </ B> repeat these evaluation and comparison steps if the difference between the instantaneous value BPi and said average value BPm is greater < B> to </ B> a predetermined threshold value and <B> to </ B> deduce a non-temporary change in bandwidth when this difference remains greater than <B> at the predetermined threshold value during a predetermined number of successive evaluations of the instantaneous bandwidth value.

The means for setting up configurations 40 comprises means 42 for choosing a configuration mode for each printer as a function of the available bandwidth.

These means of choice 42 preferably operate with a pre-recorded configuration table 43 which comprises in this example five registers MI <B> to M5 </ B> for storing for each type of printers, stored in M1, and for each interval of bandwidth whose lower and upper bounds are respectively stored in M2 and M3, a configuration mode whose characteristics are stored in M4. A fifth <B> M5 </ B> register an icon associated with <B> to </ B> each configuration mode that allows to view the configuration mode applied <B> to </ B> the printer for inform the user.

From the calculated bandwidth value, the choice means 42 selects a printer configuration from the configuration table 43 and the day 44 enable means to apply this configuration mode chosen <B> to </ B> the printer.

Day-to-day icon-setting means 45 cooperate with the display means <B> 36 </ B> described above to display the chosen configuration mode for each printer <B> II, respectively. </ B> and 12 accessible.

Thus, the icon of the first printer <B> Il </ B> is in solid lines, which indicates that this printer <B> It </ B> can be used satisfactorily with the bandwidth available on the network , while the icon of the second printer 12 is grayed out to indicate that this printer is only usable in a degraded mode (with a lower printing resolution for example) because of the bandwidth currently available on the printer. network.

The means of choice 42 and of setting <B> to </ B> day 44 are adapted <B> to </ B> reiterate the choice of a configuration mode and the setting <B> to </ B> day if configuration from <B> to </ B> whenever a non-temporary change in bandwidth is detected.

The setting device also cooperates with the default printer selection means described above which makes it possible to select a printer having a similar configuration mode. the configuration mode of the default printer previously selected.

The mobile computer <B> 10 </ B> comprises thirdly a device for processing a document illustrated in detail <B> to </ B> in FIG. 12.

This processing device here makes it possible to print a document P. <B> It </ B> comprises means of degradation <B> 50 </ B> which cooperate with the means for evaluating the available bandwidth 41 previously described. .

The degradation means <B> 50 </ B> include means for comparing <B> 51 </ B> the available bandwidth with a threshold value, computing means <B> 52 </ B> of a transfer time of the document P depending on the size of the document and the available bandwidth when this available bandwidth is less than the threshold value, comparison means <B> 53 </ B> of the transfer time with a predetermined acceptable transfer time value and degradation means 54 of one or more parameters available in this document P as long as the transfer time remains greater than <B> at </ B>. predetermined acceptable transfer duration value.

The calculation means <B> 52 </ B> are adapted <B> to </ B> transform the document P into a set of digital data, <B> to </ B> calculate the number of bits <B> to </ B> print and <B> to </ B> divide this calculated number of bits by the associated rate value <B> to the available bandwidth. The parameters available to degrade the document P can be stored and possibly classified in a parameter table <B> 55. </ B> These parameters can be entered by the user who can determine the order in which they will be chosen by the users. degradation means 54 for degrading the document.

These available parameters can include the number of color or grayscale shades used in the document, the scaling factor applied <B> to </ B> the printing of the document, and the type of <B> to < / B> process included in the document, such as graphics, drawings or images.

Printing means <B> 56 </ B> cooperate with the degradation means <B> 50 </ B> to print the document, possibly degraded, when a request <B> to </ B> has been issued by the user and received by means of receiving a request <B> 57. </ B>

Of course, the mobile computer <B> 10 </ B> could contain only one of the three devices described above or any combination of two of them.

Such a computer <B> 10 </ B> incorporating in its microprocessor <B> 100 </ B> the aforementioned devices is illustrated <B> to </ B> 13. </ B>

A read-only memory <B> 101 </ B> is suitable for storing a program to <B> to </ B> a day a list of accessible processing devices <B> to </ B> from the mobile computer <B> 10, </ B> to update the configuration characteristics of the accessible processing devices and to process a document based on the available bandwidth.

A RAM 102 includes registers adapted to store modified variables during the execution of said program.

This <B> 100 </ B> microprocessor is built into the <B> 10 </ B> computer that can be connected to <B> different processing devices, for example , a modem <B> 15, </ B> a printer 14 or a fax <B> 17 </ B> directly through an I / O card <B> 111 </ B> or by the communication network <B> 1 intermediate. </ B> This <B> 10 </ B> computer has a communication interface <B> 110 </ B> that can be connected to the communication network <B> 1 < / B> to receive or send computer queries and transfer or receive documents.

The computer <B> 10 </ B> further comprises document storage means, such as a hard disk <B> 10, </ B> or is adapted <B> to </ B> cooperate by means diskette drive <B> 107, </ B> of a <B> 108 </ B> compact disk drive, or a computer card reader <B> 109 </ B> with storage of removable documents, respectively <B> 7 </ B> disks, <B> 8 </ B> compact disks (CD) or <B> 9 </ B> computer cards (PC-CARD).

These fixed or removable storage means may further comprise the code of the method according to the invention, which, once read by the microprocessor 100, will be stored in the disk. hard <B> 106. </ B>

<B> A </ B> variant title, the program allowing the device to implement the invention can be stored in ROM <B> 101 </ B> (ROM).

In the second variant, the program can be received to be stored as previously described via the communication network <B> 1. </ B> The computer <B> 50 </ B> also has a screen <B> 103 </ B> allowing for example to interface with an operator <B> to </ B> using the keyboard 104 or the mouse <B> 105 </ B> or any other means. This <B> 103 </ B> screen constitutes the display means <B> 37 </ B> which makes it possible to display the list of printers accessible in a given place, the default printer and their respective configuration mode in depending on the bandwidth available <B> at </ B> at a given moment.

CPU <B> 100 </ B> (CPU) will execute the instructions for <B> to </ B> the implementation of the invention. When powering up, the programs and methods relating to the invention stored in a non-volatile memory, for example the read-only memory, are transferred into the random access memory. 102 (RAM) which will then contain the executable code of the invention as well as the necessary variables <B> to </ B> the implementation of the invention.

Thus, the read-only memory <B> 101 </ B> will notably store the period of calculation of the available bandwidth, the threshold value T used to detect the changes in available bandwidth, the maximum threshold value <B> C < / B> for the instant bandwidth evaluation counter, the minimum bandwidth BPs value used to degrade a document, the acceptable <B> Do </ B> processing time, the list of accessible printers <B> 30, </ B> the configuration table 43 and the table of available parameters <B> 55 </ B> to perform the degradation of a document. The RAM 102 includes registers for storing in particular the list of accessible printers <B> 30 </ B> to </ B> day depending on the location of the computer <B> 10, </ B > the default printer, the calculated average bandwidth value, the change variable, the instantaneous bandwidth evaluation count <B>, the document size <B> to </ B > treat and calculated processing time <B> D </ B>.

A communication bus 112 allows communication between the different sub-elements of the computer <B> 10 </ B> or linked <B> to </ B> him. The representation of the bus 112 is not limiting and in particular the microprocessor <B> 100 </ B> can communicate instructions <B> to </ B> any sub-element directly or via another subelement.

Figure 14 illustrates a mobile computer <B> 10 </ B> as previously described associated with a radio module 20 for detecting changes in available bandwidth.

This radio module 20 is associated <B> with <B> 10 </ B> using the input-output port <B> 111. It can send and receive data in the form of electromagnetic waves.

The radio module 20 has composed of a main data processing circuit 200, associated with a ROM 201, a RAM 202 and a <B> with </ B> B> a link interface 21 <B> 1. </ B> The ROM 201 typically contains operating programs of the main processing circuit (CPU) 200, while the RAM 202 temporarily stores the data received from the main processing circuit 200. another analog radio module connected to the wireless communication network 2 as well as the data processed by the main processing circuit 200. In particular, a program called SNMP agent (in English Simple Network Management Protocol), responsible for collecting information on the quality of the radio link and responding to SNMP requests, is running constantly. The RAM 202 thus stores the statistics read on the network to measure the instantaneous bandwidth that can consist of a number of bytes transmitted during the duration of a test or the signal power received by the radio module.

The main data processing circuit 200 is connected to a modulation and demodulation circuit (Modem) 203, converting the binary information streams into analog signals.

Modem <B> 203 </ B> is connected <B> to </ B> an RF stage 204 which provides the amplification of the signals and their transposition in frequency. Finally, the RF stage 204 uses an antenna 205 to receive and transmit the radio waves.

Interface 21 <B> 1 </ B> is an Ethernet interface for exchanging data as well as control messages. In particular, the computer <B> 10 </ B> can request the radio module 20 the instantaneous value of the quality of the radio channel using the SNMP protocol. This instantaneous value is processed in a manner to obtain the value of the instantaneous bandwidth that is compared to the average bandwidth value stored in the random access memory 102. computer <B> 10. </ B>

This mobile computer <B> 10 </ B> equipped with a radio module 20 thus makes it possible to detect the changes in available bandwidth on the wireless communication network 2 in order to set the configuration to <B> at the latest. printers and / or degrade the contents of a document based on this available bandwidth.

The present invention thus makes it possible to optimize the processing, and in particular the printing of a document <B> to </ B> from a computer connected <B> to </ B> a communication network.

It applies, but not limited to, particularly <B> to </ B> a mobile computer, connected <B> to </ B> a wireless communication network.
