Abstract
The invention provides a network system wherein connection maintenance of an optimum channel is controlled according to the type of an application program and a use state. The application program of a terminal 1 connected to a channel carries out inter-application communication with the application program of a server 3. When a period (non communication period) of receiving no packet from the terminal 1 exceeds a prescribed time, an access point 2 interrupts the channel of the terminal 1. Further, the access point 2 broadcasts a broadcast packet B for a prescribed time. The terminal 1 classifies types of application programs depending on the types and the use states and determines a system of maintaining the connection of a channel by each type. Then the terminal 1 determines/executes a system in matching with the start/end of the application program. The terminal 1 transmits a dummy packet so as to avoid the channel from being interrupted before the non communication period reaches a broadcast prescribed time.
Description
Technical field
The present invention relates to being connected and cut-out of loop between communication repeating device and the communication terminal.
Background technology
In the past, when utilizing the communication repeating device that a plurality of communication terminals are connected with the internet via dissipating public loop, although inoperation communication terminal, but if under the situation that keeps the link circuit state, then because the communication cost increase, therefore if (do not send grouping during) exceeds schedule time the no communication period of communication terminal, and then the communication repeating device is mandatory cuts off the loop.But if the afore mentioned rules time is shorter, then the problem of Chan Shenging is, incites somebody to action cut-off loop at once, and must connect again.If the afore mentioned rules time is longer, then communication cost is not thought so cheap sometimes.Therefore propose a kind of scheme, promptly the communication repeating device utilizes the port numbers of communication packet, differentiates the application kind (UUCP or TELNET etc.) in the use, and the communication repeating device changes the afore mentioned rules time (for example, patent documentation 1) according to using kind.
In addition, with between communication terminal and the server by the wireless wireless relay device that carries out relaying too, if the no communication period of the communication terminal after the loop connects exceeds schedule time, then cut off the loop of this communication terminal.This be because, if the communication terminal that will abend or break down or move to the extra-regional portable communication terminal device that can carry out radio communication and keep loop-coupled state, this will increase the administrative expenses that a plurality of communication terminals of management are used, and then the performance of communication system and stability are reduced.In this case, exist too in order to connect and the problem of formality trouble again.Particularly when wireless relay device or server authenticate communication terminal, also must the transmitting-receiving key etc., the problem of generation is, the traffic is increased, and adds the spended time for authentication.Therefore, in order to prevent that communication terminal sends every short interval and keeps the sky grouping that the loop connects usefulness under the situation about having because of no communication period cut-off loop takes place.
Yet, loop state (communications status) condition of severe of communication terminal is also arranged.The situation that in radio communication, often has received-signal strength to reduce.Therefore a kind of scheme is proposed, it is to use the word processor spanned file, and with the file that generates via in the communication terminal of network entry on server, when network is unusual, figure marker tape * the mark of the word processor on the display is shown, by allowing the user know that unusual (for example, patent documentation 2) appear in network like this.In this communication terminal, when the server that is connected with network is called out, according to there being no response to detect the unusual of network.In addition, also propose a kind of scheme, promptly in comprising the communication system that sends terminal and receiving terminal,, judge communications status (for example, patent documentation 3) according to moving and the packet loss rate from receiving the average of shake that divides into groups to calculate.

But, in the invention shown in the above-mentioned patent documentation 1,, therefore have to utilize the port numbers of communication packet to differentiate kind because the communication repeating device is differentiated the kind of using.For this reason, the problem of existence is, can not differentiate the more application, the application kind that for example form calculates and file generates of upper level than UUCP and TELNET etc., can not carry out corresponding loop according to the kind of the application of upper level and cut off control.In addition, the problem that also has is, because the communication repeating device is differentiated the kind of using, therefore can not carry out suitably handling accordingly according to the behaviour in service of using etc.In addition, sending in the method for empty grouping every short interval, will produce the problem that meaningless use of communication band and power consumption increase in order to keep the loop to connect.
In the invention shown in the patent documentation 2, owing to only utilize the demonstration form of icon to allow the user know that network is unusual, therefore take place when unusual at network, if the user does not note above-mentioned demonstration form and the operation communication terminal installation, carry out the file login or the renewal of server, the danger that produces problems such as server file destruction is then arranged.Produce such problem and be because, in application software such as word processor or form calculating, the reply communication disruption though tackled with application software, does not have the big prerequisite design that is changed to loop state, and is perhaps wrong in application software.
The present invention is just in order to address the above problem, as problem of the present invention be to provide can be according to the kind and the behaviour in service of application program, carry out best loop and connect the network system of keeping control.

Below, with reference to description of drawings example of the present invention.Figure 1 shows that the formation of the network system that the present invention is relevant.In this network system 100, server 3 is connected with networks such as wired lans with access point 2, communicates between server 3 and access point 2.Between terminal installation 1 and access point 2, utilize WLAN etc. to communicate.In addition, utilize the IAC of the application program described later of application program (the being expressed as APP in the drawings) 3a of server 3 and terminal installation 1, can upgrade from the file (not shown) of 1 pair of server 3 of terminal installations such as personal computer or wireless portable terminal or read.In addition, also can constitute terminal installation 1, visit not shown server via the internet.
Figure 2 shows that the formation of the relevant terminal installation of the present invention 1.(a) expression hardware constitutes, and (b) expression software constitutes.The sound input-output unit 16 that carry out radio communication I/F unit 14 that radio communication uses with access point 2, uses as display unit 15 such as the keyboard 12 of operating unit and mouse 13, LCD and VoIP (Voice over IP) is connected with control unit 11.In control unit 11, store radio communication driver 26, make I/O driver 27, OS (operating system) 25, the connection of action usefulness such as display unit 15 and keyboard 12 keep program 21, loop state supervisory programme 22, attendant exclusion program 23 and application program 24, by each program behavior, realize the function of terminal installation 1.In the above-mentioned program, it is the relevant programs of the present invention that program 21, loop state supervisory programme 22 and attendant exclusion program 23 are kept in connection.
Connect that to keep program 21 be to connect to keep and do not cut off program with the loop of access point 2.Loop state supervisory programme 22 and attendant exclusion program 23 are when loop state (communications status) is bad or prediction makes when worsening keyboard 12 and mouse 13 forbid that application programs 24 operates the program of usefulness.Detailed content about them will be narrated in the back.In addition, application program 24 is to carry out that form calculates or employed programs such as file generation, VoIP, homepage reading.
Figure 3 shows that the formation of the relevant access point of the present invention 2.(a) expression hardware constitutes, and (b) expression software constitutes.Access point 2 is made of control unit 31, radio communication I/F unit 32 and wire communication I/F unit 33.Utilize radio communication I/F unit 32 and terminal installation 1 to carry out radio communication, utilize wire communication I/F unit 33 and server 3 to carry out wire communication.Storing control program 34, radio communication driver 35 and wire communication driver 36 in control unit 31.This control program 34 carries out the control that access point 2 and loop between the terminal installation 1 are connected and cut off, terminal installation 1 after the loop connects if do not send grouping (grouping that application program 24 sends (hereinafter referred to as the APP grouping) or empty grouping described later etc.), then cuts off the loop with this terminal installation 1 at the appointed time.The above-mentioned stipulated time is called break time, with terminal installation 1 do not send grouping during be called no communication period.Have again,, make a plurality of terminal installations 1 know break time together by will broadcasting (broadcast) break time.The present invention is owing to be that relevant above-mentioned loop connects the invention of keeping, therefore about between server 3 and the access point 2 communicate by letter and terminal installation 1 and server 3 between the data of receiving and dispatching etc., then omission explanation.
Figure 4 shows that in terminal installation 1 data that manage usefulness are kept in the connection in loop.APP type list 41, surplus time the 42, the 2nd mode request time 43 and the 3rd mode request time 44 are to control unit 11 predefined data by network manager.Empty grouping remaining time 45 and broadcast reception value 46 be stored in control unit 11 can read/write the data of memory block (not shown).Each data below is described.APP type list 41 is tables of keeping the identifying information of the mode login application program 24 that the loop connects usefulness for each.Here, APP24a, 24b login as the 1st type, and APP24c, 24d login as the 2nd type, and APP24e, 24f login as the 3rd type.
In the action of the application program 24 of the 1st～the 3rd type, adopt the 1st～the 3rd mode respectively.That is, make the type of application program 24 corresponding with the mode of keeping loop connection usefulness.In three types priority is arranged, the priority of the 1st type is minimum, and the priority of the 3rd type is the highest.Thereby, in the time of in the program of the program of the 2nd type and the 3rd type is moved simultaneously, adopt the 3rd mode, in the time of in the program of the program of the 1st type and the 2nd type is moved simultaneously, adopt the 2nd mode.In addition, each terminal installation 1 is not necessarily installed identical application program 24, the installation that has the 1st whole types～the 3rd type, what also have has only installed the 2nd type.Here, establish application program 24 type quantity and to keep the mode that the loop connects usefulness be 3, but have no reason only to be defined in 3, also can be 1,2,4 or more than or equal to 4.
The 1st mode is the mode that does not send the grouping (hereinafter referred to as the sky grouping) of keeping the loop and connecting usefulness.Though this mode connects and to keep on this point poorly carrying out the loop, does not produce because of sending the empty traffic that increases of dividing into groups.The 2nd mode is no communication period sends empty grouping before arriving above-mentioned break time, from terminal installation 1 a mode.By the empty grouping of such transmission, prevent access point 2 cut-off loops when not sending the APP grouping.This mode also is to send the mode that the loop connects the necessary MIN empty grouping of usefulness of keeping.The 3rd mode is no communication period if certain time, then send the mode of empty grouping.As above-mentioned certain hour, because use than the value (being made as 1 second) of enough weak points break time, therefore sends the sky grouping with 1 second interval here when not sending the APP grouping.The concise and to the point action of three kinds of modes has been described here, but also can have adopted the mode that is different from above-mentioned explanation.
The type of each application program 24 is considered to be determined the behaviour in service of application program 24 etc. by network manager in response to the suffered effect of cut-out with what or loop of the communication operation of program 24 itself.For example, even for cut-off loop but the also fewer application program 24 of disadvantage, then decision is the 1st type.For as if the cut-off loop application program 24 that then disadvantage is big, then determine to be the 2nd type.For the application program 24 of VoIP, then decision is the 3rd type.Terminal installation 1 majority that uses VoIP is in moving.In the 2nd mode, if the empty grouping of transmission when communications status is abominable then might empty grouping not be access in a little 2 receptions, the loop cuts off.In addition, owing to do not have acoustic compression with VoIP, therefore the APP grouping is interrupted when noiseless, even but the short time cut-out, the user is also awkward.According to above reason, for the application program 24 of VoIP, then decision is the 3rd type.
The surplus time 42 uses with respect to having surplus break time for the transmitting time that makes empty grouping in the 2nd mode.For example, be 10 seconds in break time, if no communication period is 8 seconds (10 seconds-2 seconds), then above-mentioned connection was kept program 21 and sent empty grouping when being 2 seconds the surplus time 42.Why do like this, although be because sent empty grouping, sometimes because propagation delay etc., access point 2 can not receive empty grouping in break time, and the loop is cut off.Below, establish the surplus time 42 and be and described in 2 seconds.
The 2nd mode request time 43 be when adopting the 2nd mode request be used as break time (hereinafter referred to as the change request of break time), with time of default break time of replacing access point 2 broadcasting.The 2nd mode request time 43 is owing to being to use in order to reduce the empty transmission number of times that divides into groups, and is therefore long than default break time.To divide into default break time is 10 seconds, and the 2nd mode request time 43 is 20 seconds, describes.If the 2nd mode request time 43 sends to access point 2, access point 2 (correctly being control program 34) is accepted the change request of break time, then, broadcast the 2nd mode request time 43, replace the default break time of setting in the access point 2 from next time broadcasting.
The 3rd mode request time 44 be when adopting the 3rd mode request be used as break time, with time of default break time of replacing access point 2 broadcasting.The 3rd mode request time 44 is owing to also being uses for the platform number that carries out loop-coupled terminal installation 1 with access point 2 is increased, therefore than lacking default break time.For example, although, still be connected with the loop for a long time if use a plurality of terminal installations 1 of VoIP not send APP grouping or empty grouping, then the problem of Chan Shenging is, the table size of the office terminal device 1 of access point 2 one sides will increase, and memory areas is not enough, and perhaps communication capacity reduces.In order not produce this problem, establish the 3rd mode request time 44 and be the time shorter than default break time.Below, establish the 3rd mode request time 44 and be and described in 5 seconds.Utilize the situation of change request, acceptance and broadcasting and the 2nd mode request time 43 of the break time that the 3rd mode request time 44 carries out to carry out equally.
Be to use, send empty the grouping remaining time before in the 2nd or the 3rd mode empty remaining time 45 of dividing into groups.Empty grouping remaining time 45 in the 2nd mode with broadcasting the break time-surplus time 42} carries out initialization, in the 3rd mode to carry out initialization in 1 second.Then, carry out the subtraction counting at regular intervals,, then send empty grouping if empty grouping becomes 0 remaining time 45.In addition, initialization is to carry out under the situation when sending APP grouping or empty grouping etc.Broadcast reception value 46 be will broadcasting the value that writes the memory block break time, be some values of default break time, the 2nd mode request time 43 or the 3rd mode request time 44.
Figure 5 shows that in access point 2 for the connection of management loop and cut-out and the data of using.Be by network manager predefined data in control unit 31 default break time 47, is when no communications status continues until default time, above-mentioned [default break time (10 seconds)] before the cut-off loop.
Terminal installation admin table 48 is tables that the state of the terminal installation 1 after management loop connects is used, and comprises Termination ID 48a, cuts off 48b remaining time, asks to have or not to accept 48c, style number 48d and request time 48e.Termination ID 48a is the information of identification terminal device 1 usefulness.Here represent with 3 bit digital as Termination ID 48a, but can use MAC Address etc.Cut-out 48b remaining time is when no communications status continues until the remaining time before the cut-off loop, carry out the subtraction counting at regular intervals, if utilize the subtraction counting to make cut-out 48b remaining time become 0, then control program 34 cuts off the loop of these terminal installations 1.In addition, if receive APP grouping or empty grouping, cut-out 48b remaining time that then sends the terminal installation 1 in source carries out initialization with initial value described later.
Request has or not the change request that 48c represents whether to accept above-mentioned break time of accepting, and the terminal installation 1 for accepting is [having], and the terminal installation 1 for refusal is [nothing].In addition, when connecting, be set at [nothing] in the loop.To narrate in the back about the determining method of whether accepting the request of changing.Style number 48d is the style number ([2] or [3] of representing the 2nd or the 3rd type) with the 2nd or the 3rd mode request time 43 or 44 application programs 24 that receive in when request change break time, uses when whether decision accepts the change request.Request time 48e is the 2nd or the 3rd mode request time 43 of reception when break time, change was asked or some request times of 44.Thereby the initial value that cuts off 48b remaining time has or not when accepting 48c for [having] in request, is request time 48e, have or not when accepting 48c in request for [nothing], and be default break time 47.
Figure 6 shows that the broadcast packe B of access point 2 broadcasting.This broadcast packe B comprises that promptly asking to accept part and the terminal installation 1 that change is asked for refusal and the data that do not change the terminal installation 1 of request for the data of the terminal installation 1 of the change request of accepting break time is default part.The NUL code of default part is the signal of the default part of expression, equates with default break time 47 shown in Figure 5 this default break time.Termination ID and request time that each terminal installation 1 of part is accepted in request equate with the Termination ID 48a and the request time 48e of terminal installation admin table 48.Thereby, if the terminal installation 1 from having received broadcast packe B if do not include the Termination ID of oneself among the broadcast packe B, becomes the break time of broadcasting then default break time.In addition, in this example,, then, therefore count the capping value for the platform of the terminal installation 1 of accepting the change request because the size of broadcast packe B increases, and the airtime prolongs if accept the change request of whole break times.
Fig. 7 is the sequential chart of the action of expression terminal installation 1 and access point 2.Below, with reference to an example of the action of flowchart text terminal installation 1 and access point 2.Access point 2 is broadcasted broadcast packe B with certain broadcast cycle (being set at 2 seconds in this example).Application program 24 is according to the sequential firing of APP24a, APP24c, APP24e, according to the order end of APP24e, APP24c, APP24a.This APP24a, APP24c, APP24e are respectively the application programs 24 (with reference to Fig. 4) of the 1st, the 2nd, the 3rd type.Even at the APP24a prestart, access point 2 also sends the beacon electric wave at any time, replys by terminal installation 1, is connected with the loop of the terminal installation 1 of replying.Also can be when connecting, 3 pairs of terminal installations 1 of access point 2 or server authenticate, only link circuit when regular the authentication.Terminal installation 1 after the loop connects is preserved the data of the break time among the broadcast packe B as broadcast reception value 46.But, because 24 1 actions of application program are not carried out yet, neither send the APP grouping from terminal installation 1, also do not send empty grouping, so after the connection of loop, if through default break time 47, then the loop will cut off.
At first, if starting APP24a then sends connection request grouping (not shown) from terminal installation 1, thus link circuit.At this constantly, because APP24a is the 1st type, therefore adopt the 1st mode to connect the mode of keeping as the loop.In the 1st mode, owing to do not send empty grouping, therefore if no communication period surpasses default break time 47, then the loop is cut off.Here, suppose that APP24 suitably sends APP grouping (not shown), the loop is not cut off.
Then, if starting priority is higher than the APP24c of the 2nd type of APP24a, then adopt the 2nd mode.In the 2nd mode, { broadcast reception value 46-surplus time 42} (this broadcast reception value 46 constantly is the default break times among the broadcast packe B1) then sends empty grouping from terminal installation 1, prevents that the loop from cutting off if no communication period becomes.In addition, when APP24c starts,, send the change request grouping that comprises the 2nd mode request time 43 and style number ([2]) from terminal installation 1 in order to carry out the change request of break time.In the access point 2 that has received change request grouping, whether decision accepts the change request.Here, suppose to accept the change request.Its result broadcasts the 2nd mode request time 43 as break time to this terminal installation 1 in broadcast packe B2～B3.Thereby after this moment, { the 2nd mode request time 43-surplus time 42} then sends empty grouping if no communication period becomes.
Then, if starting priority is higher than the APP24e of the 3rd type of APP24c, then adopt the 3rd mode.In the 3rd mode, if no communication period becomes 1 second, then send empty grouping from terminal installation 1, prevent that the loop from cutting off.The broadcast reception value 46 in this moment is the value that depends on broadcast packe B3, is the 2nd mode request time 43.In addition, when APP24e starts,, send the change request grouping that comprises the 3rd mode request time 44 and style number ([3]) from terminal installation 1 in order to carry out the change request of break time.In the access point 2 that has received change request grouping, whether decision accepts the change request.Here, also hypothesis is accepted the change request.Its result broadcasts the 3rd mode request time 44 as break time to this terminal installation 1 in broadcast packe B4～B5.
Then, if the APP24e of the 3rd type finishes, then adopt the 2nd mode.Even here in order also to carry out the change request of break time, send the change request grouping that comprises the 2nd mode request time 43 and style number ([2]).Here, also hypothesis is accepted the change request.Its result broadcasts the 2nd mode request time 43 as break time to this terminal installation 1 in the later broadcast packe of B6.Then, if the APP24c of the 2nd type finishes, then adopt the 1st mode.In the 1st mode,,, therefore do not send change request grouping owing to do not connect the control of keeping usefulness in terminal installation 1 one sides.But, also can send also and can replace change request grouping with the notice of default break time 47 as the content of break time.Then, if APP24a finishes, no communication period arrives the 2nd mode request time 43, and then access point 2 cuts off the loop of terminal installation 1.
Fig. 8 and Fig. 9 are that the flow chart of the action of program 21 is kept in the action of expression terminal installation 1, i.e. connection.Connection is kept program 21 and is monitored following incident at any time, is starting and end, reception, the timer signal that takes place at regular intervals of broadcast packe B and grouping (APP grouping) transmission that utilizes application program 24 of application program 24, if detect the incident of having taken place, then carry out handling accordingly with incident.In addition, take place in order to make incident, or detect, connect the program of keeping 21 and give an order, perhaps with reference to the OS25 information of managing to OS25.For example, the starting of application program 24 and end are to detect by the active task list under the reference OS25 management.
At first, illustrate to connect and keep the action of program 21 when detecting application program 24 and reset.When not having the loop to connect (S10:Y of Fig. 8), connect the program of keeping 21 and send connection request grouping (S11).If access point 2 receives this connection request grouping, then the loop connects.In fact, though be to connect the program of keeping 21 to generate the connection request grouping, and accepted the radio communication driver transmission connection request grouping that connection request divides into groups by OS25, hypothesis is to connect the program of keeping 21 transmission connection requests to divide into groups here.About this point, wait too for change request grouping.
At this constantly, when the application program 24 of the 3rd the highest mode of priority is just moved before this (S12:Y),, do not need to shift gears, so processing finishes owing to adopt the 3rd mode.In addition, the application program 24 of the 3rd type that priority is the highest is failure to actuate and the application program 24 of new starting when being the 3rd type (S12:N and S13:Y) before this, adopt the 3rd mode, (S14), send the change request grouping (S15) of the style number ([3]) that comprises the 3rd mode request time 44 and application program 24 to access point 2.Have, empty grouping remaining time 45 is to carry out initialization (S16) in 1 second again.
In S13, not the application program 24 of the 3rd mode (S13:N) and the 2nd type when just moving before this (S17:Y) in the application program 24 that is judged to be new starting, owing to do not need to change i.e. the 2nd mode of present mode, so processing finishes.In addition, under the situation that the application program 24 of the 2nd type is failure to actuate before this (S17:N), when the application program 24 of new starting is the 2nd type (S18:Y), adopt the 2nd mode, (S19), send the change request grouping (S20) that comprises the 2nd mode request time 43 and style number ([2]) to access point 2.Have, the empty remaining time 45 of dividing into groups is so that { broadcast reception value 46-surplus time 42} carries out initialization (S21) again.In addition, when the application program 24 of new starting is not the 2nd type (S18:N), when promptly being the 1st type, adopt the 1st mode (S22).
Below, the action that connects when keeping program 21 and detecting application program 24 and finish is described.Even finish but the application program 24 of the highest the 3rd type of priority in action the time (S40:Y of Fig. 9) in certain application program 24, owing to do not need to change i.e. the 3rd mode of present mode, so processing finishes.The application program 24 of narration the 3rd type is not the situations of (S41:Y) when (S40:N) and the application program 24 that finishes are the 3rd type in action below.In this case, if the application program 24 of the 2nd type is in action (S42:Y), then, therefore adopt the 2nd mode (S43), send the change request grouping (S44) that comprises the 2nd mode request time 43 and style number ([2]) to access point 2 because the priority of the 2nd type becomes the highlyest.Have, sky divides into groups to carry out remaining time 45 initialization (S45) again.With last different be that if the application program 24 of the 2nd type is not in action (S42:N), then whether the application program 24 with the 1st type is irrelevant in action, adopts the 1st mode (S46).This be because, in the 1st mode, keep for the loop connects, do not handle especially.
In addition, in the application program 24 of the 3rd type is not (S41:N) when (S40:N) and the application program 24 that finishes are not the 3rd type in action, if the application program 24 of the 2nd type is in action (S47:Y), then keep i.e. the 2nd mode of present mode.With last different be, then to adopt the 1st mode (S48) if the application program 24 of the 2nd type is not in action (S47:N).In the above description, when the 3rd mode becomes the 1st mode, and when the 2nd mode becomes the 1st mode, do not send advise of same in the mode that adopts to access point 2 from terminal installation 1, but also can notify the variation of this mode, use default break time 47 as break time at access point 2.
Below, illustrate that the connection when detecting APP grouping and send keeps the action of program 21.In this case, when present mode is the 2nd or the 3rd mode (S30:Y of Fig. 8), when promptly carrying out the transmission control of empty grouping, remaining time 45 is carried out initialization (S31) according to present mode in empty grouping.That is, when present mode was the 2nd mode, empty grouping remaining time 45 was so that { broadcast reception value 46-surplus time 42} carries out initialization, and when present mode was the 3rd mode, empty grouping remaining time 45 was to carry out initialization in 1 second.
Below, illustrate that the connection when detecting timer signal keeps the action of program 21.When present mode is the 2nd or the 3rd mode (S50:Y of Fig. 9), sky divides into groups to carry out remaining time subtraction counting (S51).If utilize the subtraction counting, empty grouping becomes 0 (S52:Y) remaining time 45, then sends empty grouping (S53), and identical with above-mentioned S31, remaining time 45 is carried out initialization (S54) according to present mode in empty grouping.
Below, illustrate that the connection when detecting the reception of broadcast packe B keeps the action of program 21.At first, take out the break time (S60) of oneself from broadcast packe B shown in Figure 6.In this takes out, if accept part the identical Termination ID of ID with own (terminal installation 1 of reception broadcast packe B) is arranged in the request of broadcast packe B, then take out this request time, as if there not being identical Termination ID, then take out the default break time of default part.When equate with broadcast reception value 46 break time of taking out (S61:Y), owing to do not need to upgrade broadcast reception value 46, so processing finishes.Be worth under the 46 unequal situations (S61:N) in the break time and the broadcast reception of taking out, when present mode is not the 2nd mode (S62:N), be kept at memory block (S65) as broadcast reception value 46 break time of taking-up.When present mode is the 2nd mode (S62:Y), promptly accept change request according to change request grouping, when broadcasting the 2nd mode request time 43, because the delivery time of empty grouping changes, therefore send empty grouping (S63), the empty remaining time of dividing into groups is so that { the 2nd mode request time 43-surplus time 42} carries out initialization (S64), again is kept at memory block (S65) as broadcast reception value 46 break time of taking out.
Figure 10 be the expression access point 2 action, be the flow chart of the action of control program 34.Control program 34 monitors following incident at any time, promptly receive connection request grouping, receive change request grouping, receive the APP grouping, produce timer signal and every broadcast cycle at regular intervals and produce the broadcasting index signal, if the incident that detects takes place, then carry out handling accordingly with incident.
The action of the control program 34 when detecting the grouping of reception connection request at first, is described.In this case, the data entry of terminal installation 1 that sends the source in terminal installation admin table 48, will be carried out initialization (S70) break time.Specifically, the ID that sends the terminal installation 1 in source is recorded among the Termination ID 48a of terminal installation admin table 48, request has or not to be accepted 48c and is set at [nothings], cut-out 48b remaining time is arranged again to carry out initialization default break time 47.In fact, though be to receive the connection request grouping with radio communication driver 35, and by OS25, control program 34 is accepted the connection request grouping, receives the connection request grouping as control program 34 here.About this point, wait too for change request grouping.
The action of the control program 34 when detecting reception change request grouping is described then.At first, whether decision is accepted the change request and whether is cancelled accepted change request (S75).In this example owing to stipulated to accept the higher limit of platform number of the terminal installation 1 of change request, therefore if the request of terminal installation admin table 48 have or not accept 48c for the number of [having] less than higher limit, then accept the change request.In addition, also accept ownly to accept the terminal installation 1 of change request, i.e. request has or not the change request that 48c is the terminal installation 1 of [having] of accepting.
In addition, request at terminal installation admin table 48 has or not the number for [having] of accepting 48c to become higher limit, and the transmission source of change request grouping is not that oneself is when accepting the terminal installation 1 of change request, rule according to the rules, whether decision refuses the change request, perhaps whether cancel the acceptance of transmission source terminal installation 1 in addition, accept new change request.For example, if the style number 48d of accepted whole change requests is a priority the highest [3] (the 3rd type), then refuse new change request.Different therewith is, if style number 48d is arranged for [2] (the 2nd type) in the change request that oneself accepts, and the relevant style number of new change request be [3], and then the change request that style number 48d is [2] is accepted in cancellation, accepts new change request simultaneously.In addition, as mentioned above, comprise the style number of application program 24 in change request grouping, the style number 48d of such model and terminal installation admin table 48 compares.
Then, when accepting the change request, upgrade terminal installation admin table 48 (S76).Specifically, the request of the transmission source terminal device 1 of terminal installation admin table 48 has or not to be accepted 48c and is set at [having], in style number 48d, set the style number in the change request grouping, in request time 48e, set the 2nd or the 3rd mode request time 43 or 44 in the change request grouping.Have again, when the accepting of the terminal installation 1 of cancelling other along with accepting the change request, the request of this terminal installation 1 had or not accept 48c and be set at [nothing].Then, cut-out 48b remaining time of the terminal installation 1 in the transmission source that the change request is divided into groups and the terminal installation 1 that cancellation is accepted carries out initialization (S77).Initialization is to have or not the value of accepting 48c to utilize request time 48e or default break time 47 to carry out according to request.Here broadcast packe B is not broadcasted, but here if broadcast, then terminal installation 1 can be known above-mentioned acceptance, refusal or cancellation immediately, and can connect the control of keeping usefulness immediately according to the value of new broadcasting.
Then, illustrate detecting every broadcast cycle and send the action of the control program 34 of broadcasting during index signal.If detect the broadcasting index signal, then generate broadcast packe B shown in Figure 6, and the broadcast packe B that generates is broadcasted (S80) according to terminal installation admin table 48.
Then, illustrate in the action that detects the control program 34 when sending timer signal at regular intervals.At first, cut-out 48b remaining time to each terminal installation 1 of terminal installation admin table 48 carries out subtraction counting (S85).For making cut-out 48b remaining time become 0 terminal installation 1 by the subtraction counting, the loop is cut off, the data of this terminal installation 1 are deleted (S86) from terminal installation admin table 48.That is, the terminal installation 1 for no communication period arrival break time (cutting off the initial value of 48b remaining time) cuts off the loop.The action of the control program 34 when detecting reception APP grouping is described then.In this case, because no communication period is interrupted, therefore cut-out 48b remaining time in the transmission source that APP is divided into groups carries out initialization.
More than, be that the good situation of loop state (communications status) between hypothesis terminal installation 1 and the access point 2 describes.But,, perhaps the received-signal strength of radio communication is reduced because of the change in location of terminal installation 1 etc. because of the increase of the traffic is blocked.If when loop state is bad, carry out the file renewal etc. of server 3, then as mentioned above, have to produce the danger that makes problems such as file corruption from terminal installation 1.
Therefore, if it is bad or dope deterioration that the loop state supervisory programme 22 (with reference to Fig. 2) of monitoring circuit state detects loop state, then notifying operation is forbidden program 23, the feasible operation of forbidding keyboard 12 and mouse, the attendant exclusion program 23 of having accepted this notice is just forbidden the operation of keyboard 12 and mouse 13.Do like this, the file that carries out server 3 with regard to the operation that prevents to utilize keyboard 12 and mouse 13 when loop state is bad upgrades to be handled etc.But, because therefore quiescing and inconvenient without exception under the situation about also having when pressing disengage button described later, by way of exception removes attendant exclusion.Below, loop state supervisory programme 22 and attendant exclusion program 23 are described.
Figure 11 shows that the flow chart of the action of loop state supervisory programme 22.This loop state supervisory programme 22 utilizes OS25 to start every official hour interval (for example 10 seconds intervals), detects and prediction loop state (S100).According to the various information of accepting from radio communication driver 26 by OS25, for example information such as the loss situation of reception grouping, the error rate, propagation delay, received-signal strength, obstruction mark are carried out the detection and the prediction of loop state.As Forecasting Methodology, can utilize the method shown in well-known in the past method, for example patent documentation 3 etc.Then, detecting present loop state when bad, perhaps (S101:Y) during the prediction loop state deteriorating carries out attendant exclusion notice (S102) to attendant exclusion program 23.The reason ([received-signal strength reduction] etc.) that also comprises quiescing in this notice.Having, is that the attendant exclusion flag settings of attendant exclusion state is 1 (S103) with expression again.When being marked at power connection, attendant exclusion carries out initialization.Utilize above-mentioned attendant exclusion notice, as described later, forbid the operation of keyboard and mouse 13.
On the other hand, at present loop state well and do not dope that loop state worsens (S101:N), the attendant exclusion mark is (S104:Y) simultaneously at 1 o'clock, attendant exclusion program 23 is forbidden removing notice (S105), is (OS106) to the attendant exclusion flag settings simultaneously.That is, after the attendant exclusion notice,, then forbid removing notice, as described later, can carry out the operation of keyboard and mouse 13 if loop state becomes well.In addition, above-mentioned attendant exclusion notice and forbidding is removed notice and is actually by OS25 and sends attendant exclusion program 23 to.
Figure 12 shows that the flow chart of the action of attendant exclusion program 23.This attendant exclusion program 23 is in the wait state (S110) of above-mentioned attendant exclusion notice under normal condition.If utilize loop state supervisory programme 22 to carry out the attendant exclusion notice, then remove wait state.After wait state is removed, shown in Figure 13 (a), show the dialog box 110 (S111) of greatest priority, this dialog box 110 display operation disable message 110a and disengage button 110b in the part of the picture of display unit 15 (with reference to Fig. 2).In attendant exclusion message 110a, [received-signal strength reduction] is the reason (or reason) of attendant exclusion, shows according to the reason from loop state supervisory programme 22 notices.Because the reason that such display operation is forbidden, so the user also can take adequate measures (for example, moving near the of access point 2).
In addition, because indication makes dialog box 110 become greatest priority to OS25, and accepts the operation signal of keyboard 12 and mouse 13 with attendant exclusion program 23, so forbid the operation of keyboard 12 and mouse 13 application programs 24.This illegal state if click disengage button with mouse 13, is perhaps pressed the space bar of lower keyboard 12 as described later, and then temporary transient (only in the stipulated time) removes.Here, be to forbid the operation of keyboard 12 and mouse 13, but also can adopt other method by the dialog box 110 of using greatest priority.In addition, owing to also do not note pressing space bar sometimes, therefore also can only when clicking disengage button 110b, remove illegal state with mouse 13.
After dialog box 110 showed, attendant exclusion program 23 became above-mentioned attendant exclusion notice, forbids removing the wait state (S112) of notice or [pressing disengage button 110b].Under this state,, then, show dialog box 110 (S111) again according to new attendant exclusion notice if attendant exclusion program 23 is accepted attendant exclusion notice (S113:Y).If accept to forbid removing notice (S114:Y), then delete dialog box 110 (S115), attendant exclusion program 23 becomes the wait state (S110) of attendant exclusion notice again.Like this, in a single day even become the attendant exclusion state, if loop state becomes well, then also can operation keyboard 12 and mouse 13.
In addition, under the wait state of S112.If press disengage button 110b (S114:N), then as Figure 13 (b) shown in, show reduction priority, changed the dialog box 111 (S116) of displaying contents in the part of the picture of display unit 15.Then, attendant exclusion program 23 becomes the wait state (S117) through the stipulated time (for example 10 minutes).Because the priority of above-mentioned dialog box 111 reduces, so before this stipulated time of process, can operation keyboard 12 and mouse 13.
Then, if through the stipulated time, then attendant exclusion program 23 becomes the wait state (S118) that notice was notified or forbidden removing to attendant exclusion.Owing in the above-mentioned stipulated time, carried out the attendant exclusion notice or forbidden removing notice, therefore removed wait state immediately.At this moment, will be stored in whole attendant exclusion notices of waiting for matrix and forbid removing notice and from wait for matrix, delete.At this constantly,, then show dialog box 110 (S 111) again, forbid the operation of keyboard 12 and mouse 13 if attendant exclusion is labeled as 1 (S119:Y).If attendant exclusion is labeled as 0 (S119:N), then delete dialog box 111 (S120), attendant exclusion program 23 becomes the wait state (S110) of attendant exclusion notice, can carry out the operation of keyboard 12 and mouse 13.
In above-described example, sending change request grouping when adopting the 2nd and the 3rd mode, is not essential item of the present invention but send change request grouping, even need not the 2nd and the 3rd mode request time 43 and 44, and only use default break time 47, also can implement the present invention.In addition,, when perhaps only adopting the 3rd mode, send change request grouping, also can implement the present invention even when only adopting the 2nd mode.For example, can whether be 0 also according to the 2nd mode request time of setting 43, decide connection to keep program 21 and whether send change request grouping.
In addition, in above-mentioned example, be to be illustrated, but hour etc. under the situation, also can accept the change request all the time in the higher limit of platform number that can carry out loop-coupled terminal installation 1 with access point 2 for the situation of change request that refusal break time is arranged.Have again, in above-mentioned example, be at terminal installation 1 and communication repeating device, be that the situation of carrying out radio communication between the access point 2 is illustrated, but the present invention is not limited to this, between terminal installation 1 and communication repeating device, carry out also can implementing the present invention under the situation of wire communication.Have again, in above-mentioned example, be by broadcast packe B being broadcasted (broadcast), making a plurality of terminal installations 1 know break time together, but, also can send the grouping that comprises the break time that is applicable to this terminal installation 1 to terminal installation one by one 1 as broadcasting of the present invention.The numerical value of appropriate change surplus time 42 grades has, in above-mentioned example, represented the numerical value of surplus time 42 grades, but this is to represent for example, even also can be implemented the present invention.
