Can use the high speed reads memory write of other types to replace DRAM203.Flash memory is suitable as the primary memory of storage from the basic software collection of downloaded, and this is owing to can keep its content when it cuts off the power supply, and is easy to rewriting.In addition, by utilizing battery, can use other low-speed memories such as volatile storage as redundant.
Fig. 3 represents the core image of flash memory 204.Flash memory 204 is divided into and is used to store the memory field of loading procedure 301 and file table 302 and is used to store memory field from numerous basic software collection of downloaded.
In Fig. 3, in flash memory 204, be used for storing memory field from the basic software collection of downloaded, store five kinds of different basic software collection.Five kinds of basic software collection comprise the basic software collection 303 that is used for WBT, are used for the basic software collection 304 of x terminal, are used for the basic software collection 305 of Linux terminal, are used for the basic software collection 306 and the basic software collection 307 that is used for the Java terminal of IBM3270 terminal.
WBT basic software collection 303 is made up of Windows CE and RDP software.The basic software collection 304 that is used for x terminal is made up of linux kernel and the software that is used for X Window.The basic software collection 305 that is used for the Linux terminal is made up of network file system(NFS) (NFS) stipulations of linux kernel and Connection Service device.The basic software collection 306 that is used for IBM3270 terminal (dumb terminal) is made up of with the software for display that is used for 3270 terminals Windows CE.The basic software collection 307 that is used for the Java terminal is made up of kernel, virtual machine (VM) software and applet.
Do not need all five basic software collection are downloaded to Network Termination # 1 07a to 107n.It is just enough only to be loaded in the basic software collection that uses on each network terminal down.
Below explanation is according to the operation of the network terminal of present embodiment.At first, illustrate the basic software collection is downloaded to each Network Termination # 1 07a to the operation of 107n and the operation of loading procedure 301.
By operations server 102 to 105, with in the server 102 to 105 storage, be used for the basic software collection of Network Termination # 1 07a to the compression of 107n, download to the network terminal.Basic software collection in each server only downloads to the network terminal of MAC (medium access control) address designation of the network terminal on each server.
Utilize broadcast technology, the basic software collection can be downloaded to all-network terminal 107a simultaneously to 107n from each server.
In addition, all basic software collection can be stored on the website (as principal computer), utilize broadcast technology that each basic software collection is downloaded on the all-network terminal then, or by operating on the network terminal that this website only downloads to MAC Address sign.
Moreover each network terminal also can download to each network terminal with essential basic software collection by asking wherein to store the server of required basic software collection.
In the compressive state mode, store in the flash memory 204 downloading to the basic software collection of Network Termination # 1 07a to 107n.With canned data in the flash memory 204, comprise title, start address or its size of basic software collection, be written in the file table 302 in the flash memory 204.
Fig. 5 is a process flow diagram, the operation of expression loading procedure 301, and loading procedure is used for loading and moving certain basic software collection of flash memory 204 storages.
Below referring to figs. 1 through Fig. 5, and be that example illustrates its operation with Network Termination # 1 07a.Suppose with compressive state shown in Figure 3 five kinds of different basic software collection 303 to 307 of storage in the flash memory 204 of Network Termination # 1 07a herein.
When connecting Network Termination # 1 07a, carry out the loading procedure 301 of storage in the flash memory 204.As shown in Figure 5, loading procedure 301 accessed document tables 302 (step S501) are to check whether this startup is to download the startup first time (step S502) afterwards of basic software collection.If this startup is to start for the first time, then loading procedure 301 enters the selection screen pattern, and this pattern allows the basic software of storage from flash memory 204 to concentrate the basic software collection (step S507) that selection will be carried out.Step S507 is the operation of loading procedure 301, allows the basic software collection that selection will be carried out.
As shown in Figure 4, in selecting screen pattern, the title of the basic software collection 303 to 307 that on display device 206, keeps in the display file table 302.Asterisk shown in Fig. 4 (
*) be used for identifying default basic software collection.Because this stage is not specified default basic software collection, so do not show asterisk.
If the scheduled operation of operating means has been selected arbitrary basic software collection (step S508), then, it is loaded among the DRAM203 by the selected basic software collection of decompressing function decompression of loading procedure 301, carry out then.
The basic software collection of just carrying out in DRAM203 is connected to corresponding server by transmission medium 101 with Network Termination # 1 07a, and loading procedure 301 sends initiate notification (step S510) to server.
Whether the server inspection receives initiate notification (step S601).If this server receives initiate notification, then server checks that the cumulative total of initiate notification is whether in the license count of basic software (step S602).
In the license count memory storage the nonvolatile memory in server 102 to 105, the storing authorization number.For example, if license count is 10, then server allows ten network terminals to use this application software.
If the cumulative total of the initiate notification that receives is in license count (as 10), then server allows Network Termination # 1 07a to use this application software (step S603), and the counter that provides in the server adds 1 (step S604) to total value.Step S602 and step S603 constitute approval apparatus.
In step S602, if the cumulative total of the initiate notification that receives from Network Termination # 1 07a to 107n surpasses license count (as 10), then server stops Network Termination # 1 07a to use this application software (step S605).Step S602 and step S605 constitute holdout device.Therefore, the network terminal that basic software carries out unauthorized copying is used this application software, just can realize correct License Management by prevention.
In above-mentioned steps, various improvement also are possible, for example, permit or stop to be set to default and to omit another.
At step S603, if approval apparatus allow to use application software, the application software of Network Termination # 1 07a in can long-range runtime server then.
For example, if the operation of operating means 205 has selected to be used for the basic software collection 303 of WBT, the basic software collection 303 and it is loaded among the DRAM203 of then decompressing causes carrying out Windows CE and RDP software.
By transmission medium 101 Network Termination # 1 07a is connected to terminal server 104 subsequently, and for ready as WBT, thereby make it use word processor, database or other commercial program by operated from a distance.
The actual application software of carrying out on terminal server 104 can be as carry out operation on Network Termination # 1 07a.
By on the hard disk (not shown) of terminal server 104, preserving document or other data, cut off Network Termination # 1 07a then, finish to use application software.
When cutting off Network Termination # 1 07a, the information that identifies the basic software collection that just in time uses before cut-out is written in the file table 302.
Just in time before cut-out, the loading procedure 301 of Network Termination # 1 07a sends the notice of finishing of basic software collection to server 104.Whether server 104 inspections are received and are finished notice (the step S606 among Fig. 6).If server 104 has received that this finishes notice, then the counter that provides of server subtracts 1 (step S607) from the cumulative total of initiate notification.
Among the step S502 in Fig. 5, if this startup is to start the first time of downloading after the basic software collection, then loading procedure 301 is checked the scheduled operation (step S503) of having carried out operating means 205 in the predetermined amount of time after connection whether.
If carried out predetermined operation, then loading procedure 301 enters and selects screen pattern (step S507), and shows selection screen shown in Figure 4 on display device 206.Then, the basic software collection is loaded among the DRAM203 and execution (step S508 and step S509).The basic software collection of carrying out is connected to corresponding server by LAN with Network Termination # 1 07a, and loading procedure 301 sends initiate notification (step S510) to server.
Server receives the initiate notification from the network terminal, and allows or stop to use application software (the step S601 among Fig. 6 is to step S605).If the cumulative total of the initiate notification that receives is within license count, then server allows Network Termination # 1 07a to use this application software, by this application software of the network terminal in can long-range runtime server.Because the network terminal that moves under unauthorized basic software can not use application software, so can the management software permission.
For example, predetermined amount of time can be checked the time period that Network Termination # 1 07A is spent for connecting back loading procedure 301.Also can use additive method,, replace operation device in the predetermined amount of time of energized as energized when the scheduled operation (for example, pressing certain predetermined key) of executable operations device.Although can use numerous additive methods to make loading procedure enter above-mentioned preference pattern, with the operation of connecting relevant operating means 205, for example the operation of carrying out in certain time period when energized or after energized is preferable.
In step S503, if the scheduled operation of executable operations device 205 in the section at the fixed time not, then whether loading procedure 301 accessed document tables 302 have specified default basic software collection (step S504) to check.
If do not specify the basic software collection as default, then loading procedure 301 moves the basic software collection (step S506) in the basic software collection of storing in the flash memory 204 that used last time 303 to 307, and loading procedure is to sending initiate notification with this basic software corresponding server.
For example, if the basic software collection that used last time is the basic software collection (Windows CE and RDP software) that is used for WBT, the basic software collection 303 that then decompresses is loaded into it among DRAM203, and loading procedure 301 sends initiate notification to server 104.
Server 104 receives initiate notification from the network terminal, and allows or stop and use application software (step S601 to S605 among Fig. 6).If the cumulative total of the initiate notification that receives is in the license count scope, then server allows that Network Termination # 1 07a uses application software, can be by this from the Network Termination # 1 07a application software the operations server remotely.The network terminal of operating under unauthorized basic software situation can not use application software, can realize software license management by this.
If be found to be the default and basic software collection of appointment in the file table 302 in step S504, then this basic software collection is decompressed, loads and carries out (step S505).Then, loading procedure 301 sends to server to initiate notification.
In example shown in Figure 4, the basic software collection 303 that is used for WBT is designated as default, and with asterisk "
*" sign.Therefore, basic software collection 303 is decompressed, loads in DRAM203, and carries out.Then, loading procedure 301 sends to server 104 to initiate notification.
Server receives initiate notification from the network terminal, and allows or stop and use application software (step S601 to S605 among Fig. 6).If the cumulative total of the initiate notification that receives is in the license count scope, then server allows that Network Termination # 1 07a uses application software, can be by this from the Network Termination # 1 07a Application Software Program the operations server remotely.Therefore, the network terminal of operating under unauthorized basic software situation can not use application software, by this can the management software permission.
As mentioned above, if do not carry out the scheduled operation of operating means 205, and it is default not specify the basic software collection to do, and then carries out the last basic software collection that uses.If do not carry out the scheduled operation of operating means 205, and it is default to specify a basic software collection to do, and then carries out default basic software collection.If the scheduled operation by operating means 205 is selected a basic software collection, then carry out this basic software collection.Therefore, basic software collection that can enough expectations promptly starts Network Termination # 1 07a to 107n, thereby gets ready for use.
Describe below the basic software collection of an expectation is appointed as default program.Because carry out the scheduled operation of operating means 205 in the intended duration after connection, so loading procedure 301 enters the selection screen pattern, and the selection screen shown in the displayed map 4.Because it is default not specify the basic software collection to do as yet, thus in Fig. 4, do not show asterisk (
*).
Then, the scheduled operation of the operating means 205 by being used for default appointment can be being appointed as default at any one basic software collection of selecting to show on the screen.For example, this operation can comprise: input is corresponding to the numeral 1,2,3,4 and 5 of the label of giving desired basic software collection 303 to 307.
Therefore, explicit identification be appointed as default basic software collection asterisk (
*).The basic software collection that Fig. 4 represents to be used for WBT is appointed as and is lacked the timesaving and select screen.The information of the border being known default basic software collection is written in the file table 302.
Because specify required basic software collection, just can automatically start the network terminal so only need connect the power supply of the network terminal, and need not manipulation operations device 205 with this basic software collection as default.
Fig. 7 is a process flow diagram, the operation of the server 102 to 105 of another embodiment of expression according to the present invention.The difference of Fig. 6 and Fig. 7 is to have increased step S701.This difference will be described in the following description.
According to present embodiment, in ID code (as MAC Address) the memory storage (not shown) of server 102 to 105, store the ID code of each Network Termination # 1 07a to 107n.In step S602, if the cumulative total of the initiate notification of receiving from the network terminal in license count, then server is checked the ID code (step S701) of whether having stored this network terminal in the ID code storage.Step S701 is the operation of ID code verification device.If stored the ID code of this network terminal in the ID code storage, then server allows this network terminal to use this application software (step S603).If do not store the ID code of this network terminal in the ID code storage, then server stops this network terminal to use this application software (step S605).By this configuration, the unauthorized network terminal can not use application software.
According to network of the present invention, can when starting the network terminal, start required basic software collection fast, and use application software by the network terminal that allows its ID code in server, to register, stop unauthorized software to duplicate.Therefore, can realize strict software license management easily.
In addition,, and allow the network terminal of predetermined number to use application software, can stop the unauthorized network terminal to use application software by the ID code of storage all-network terminal.
