Description

网络系统、通信中继装置、通信终端装置及通信终端装置用程序 Network system, communication relay apparatus, a communication terminal apparatus and communication terminal apparatus program

技术领域 FIELD

本发明涉及通信中继装置与通信终端装置之间的回路的连接与切断。 The present invention relates to cut off the circuit connection between the communication relay apparatus and the communication terminal apparatus.

背景技术 Background technique

以往,在利用通信中继装置将多个通信终端装置经由公用回路与因特网进行连接时,尽管不操作通信终端装置,但若在保持连接回路状态的情况下,则由于通信费用增大,因此若通信终端装置的无通信期间(不发送分组的期间)超过规定时间,则通信中继装置强制性将回路切断。 Conventionally, when a plurality of communication terminal devices via a public circuit connected to the Internet using a communication relay apparatus, while not operating the communication terminal apparatus, but if in the case of a state holding circuit is connected, then since communication cost is increased, and therefore if during communication with the communication terminal apparatus is not (does not transmit during the packet) exceeds a predetermined time, the communication relay apparatus forcibly cut off the circuit. 但是,若上述规定时间较短,则产生的问题是,将立刻切断回路,并必须进行再连接。 However, the problem if the predetermined time is short, the produce that will immediately cut off the circuit, and must be re-connected. 若上述规定时间较长,则有时通信费用不是所想的那么便宜。 If the predetermined time is longer, sometimes communication costs not think so cheap. 因此提出一种方案,即通信中继装置利用通信分组的端口号,来判别使用中的应用种类(UUCP或TELNET等),通信中继装置根据应用种类,来改变上述规定时间(例如,专利文献1)。 A solution is therefore proposed that the packet communication relay device using a communication port number, discriminates the type of application (like the TELNET or UUCP) in use, the type of the communication relay device according to the application, to change the predetermined time (e.g., Patent Document 1).

另外,将通信终端装置与服务器之间通过无线进行中继的无线中继装置也同样,若回路连接后的通信终端装置的无通信期间超过规定时间,则切断该通信终端装置的回路。 Further, the communication between the terminal device and a server for relaying wireless relay apparatus via the wireless it, exceeds a predetermined time, the communication circuit of the terminal apparatus is cut off during the non-communication with the communication terminal apparatus, if the circuit connection. 这是由于,若将异常停止或发生故障的通信终端装置、或者移动至能够进行无线通信的区域外的便携式通信终端装置保持回路连接的状态,这将增大管理多个通信终端装置用的管理费用,进而使通信系统的性能及稳定性降低。 This is because, if the abnormal stopping a communication terminal apparatus or failure has occurred, or can be moved to the portable communication terminal apparatus outside the area of ​​the wireless communication circuit connection holding state, which increases management apparatus managing a plurality of communication terminals with cost, performance and further reduce the stability of the communication system. 在这种情况下,也同样存在为了再连接而手续麻烦的问题。 In this case, also exists for the reconnection procedure troublesome. 特别是在无线中继装置或服务器对通信终端装置进行认证时,还必须收发密钥等,产生的问题是,为了进行再连接而使通信量增加,再加上为了认证而花费时间。 Especially when the wireless relay communication terminal device or server device authentication key, etc. must also be a transceiver, a problem arises that, in order to perform re-connection is increased and the amount of traffic, plus the time it takes for the authentication. 因此,为了防止因发生无通信期间而切断回路,有的情况下通信终端装置每隔短的间隔发送维持回路连接用的空分组。 Accordingly, in order to prevent the occurrence of disconnection period without communication circuit, when the communication terminal apparatus and some short intervals every null packet transmission circuit connection is maintained.

然而,也有通信终端装置的回路状态(通信状态)恶劣的情况。 However, there are circuit state (communication state) of the communication terminal apparatus bad situation. 在无线通信中往往有电波强度降低的情况。 A wireless communication radio wave tend to have reduced strength. 因此提出一种方案,它是在用文字处理软件生成文件,并将生成的文件经由网络登录在服务器上的通信终端装置中,在网络异常时,将显示器上的文字处理软件的图标带×标记进行显示,通过这样让用户知道网络出现异常(例如,专利文献2)。 One solution is therefore proposed, which is generated using a word processor file, the resulting file and network entry via the communication terminal device on the server, when the network is abnormal, the word processing software on the display icon with a mark × display, by letting the user know this anomaly (e.g., Patent Document 2) network appears. 在这种通信终端装置中,在对与网络连接的服务器进行呼叫时,根据有无应答来检测网络的异常。 In such communication terminal apparatus, when the call server connected to a network, depending on whether the response to detect abnormal network. 另外,还提出一种方案,即在包括发送终端及接收终端的通信系统中,根据从接收分组计算出的抖动的平均移动及分组损失率,来判定通信状态(例如,专利文献3)。 Also proposed is a solution, i.e. in a communication system comprising a transmitting terminal and a receiving terminal, the average packet loss rate and the jitter movement is calculated from the received packet, determines the communication state (e.g., Patent Document 3).

在专利文献2所示的发明中,由于仅利用图标的显示形态让用户知道网络异常,因此在网络发生异常时,若用户不注意上述显示形态而操作通信终端装置,进行服务器的文件登录或更新,则有产生服务器文件破坏等问题的危险。 In the invention shown in Patent Document 2, since the display form icons only let users know network anomalies, so when an abnormality occurs in the network, if the user inadvertently operates the display form of the communication terminal apparatus, a server or update log file , then there is a danger server file corruption and other issues. 产生这样的问题是由于,在文字处理软件或表格计算等应用软件中,应对通信中断,虽然用应用软件加以应对,但没有以回路状态有大的变化为前提进行设计,或者在应用软件中有错误。 Such a problem is because, in a word processor or a spreadsheet and other software applications, to deal with communication disruption, although to be addressed by the application, but not in a loop state major changes were designed on the premise, or have in the application software error.

本发明正是为了解决上述问题,作为本发明的课题在于提供能够根据应用程序的种类及使用状况、进行最佳的回路连接维持控制的网络系统。 The present invention was made to solve the above problems, the present invention is used as object is to provide an according to the type and usage of the application, the optimal loop control system to maintain the network connection.

发明内容 SUMMARY

在第1发明中,在将服务器与通信终端装置通过通信中继装置进行连接的网络系统中,服务器具有单一或多个应用程序。 In the first invention, the server in the network system with the communication terminal device connected through a communication relay device, a server having a single or multiple applications. 通信中继装置具有在回路连接后的通信终端装置的无通信期间到达规定时间时、切断该通信终端装置的回路的功能;以及将上述规定时间作为切断时间、定期广播的功能。 Communication relay device has a non-communication period after the communication terminal apparatus reaches a predetermined time of circuit connection, disconnection of the communication terminal apparatus function circuit; and the predetermined period of time as the cutting, the function of periodically broadcasts. 通信终端装置具有与服务器的应用程序进行应用间通信的单一或多个应用程序;以及根据起动的单一或多个应用程序的类型的优先级,决定与应用程序的类型相对应的维持回路连接用的方式,并根据广播的切断时间来进行该决定的方式的连接维持程序。 The communication terminal apparatus having a single or a plurality of inter-application communication applications with the application server; and a connection according to the type of starting single or multiple applications priority type determines the application corresponding to the sustain circuit connection manner, and according to the determined off time maintains the program broadcast mode.

这里,实施形态中所示的终端装置相当于上述通信终端装置,实施形态中所示的接入点相当于通信中继装置,实施形态中所示的缺省切断时间相当于规定时间。 Here, the terminal apparatus shown embodiment corresponds to the communication terminal apparatus, the access point illustrated embodiment corresponds to the communication relay means, illustrated embodiment, the default cut-off time corresponding to a predetermined time. 另外,由于应用程序的类型的优先级与维持回路连接用的方式相对应,因此可将类型的优先级称为是维持回路连接用的方式的优先级。 Further, since the priority and sustain the type of application corresponding to a circuit connection, and thus may be referred to as a type of priority is to maintain the loop mode connection to the priority. 如上所述,由于与维持回路连接用的方式相对应的应用程序的类型或类型的优先级不是由通信中继装置决定,而是由通信终端装置决定,因此能够考虑到应用程序的种类及使用状况来进行最佳的维持回路连接用的处理。 As described above, since the type or types of priorities are not determined by the communication relay device connected to the loop to maintain a manner corresponding to the application, but rather is determined by the communication terminal apparatus, it is possible to take into account the kind and application conditions to maintain optimal processing circuits are connected with. 即,用与应用程序的类型相对应的方式来进行上述处理。 That is, with the application type corresponding to the above-described process embodiment. 另外,由于上述方式是根据广播的切断时间来进行的(例如,根据广播的切断时间及自己的无通信期间,来发送空分组,使得维持回路连接用的空分组的发送次数减少),因此能够减少维持回路连接用的通信量(例如,空分组的发送量),能够提高网络系统的性能。 Further, the above embodiment is a cutting time of the broadcast is carried out (e.g., according to the off period time of the broadcast and their non-communication, transmits a null packet, so that the number of transmissions to maintain a null packet circuit connected to the reduction), it is possible to reducing the traffic used to maintain the connection circuit (e.g., a null packet transmission amount) can improve the performance of the network system. 再有,由于利用通信中继装置来广播切断时间,因此即使多个通信终端装置不要求各自通信中继装置发送切断时间,也能够在通信终端装置中根据广播的切断时间进行维持回路连接用的处理(例如,发送空分组),能够减少与该处理有关的通信量。 Further, since the communication relay apparatus broadcasts off time, even if a plurality of communication terminal apparatuses is not required to cut each time a communication relay device, can be connected to a sustain circuit in accordance with the disconnection time of the broadcast communication terminal apparatus processing (e.g., transmitting a null packet), it is possible to reduce the traffic associated with the process. 再有,在通信终端装置是用电池动作的便携式终端时,由于减少与维持回路连接用的处理有关的通信量,因此也能够抑制电池的消耗。 Further, consumption of the communication terminal apparatus is a portable terminal battery operation, due to the reduced amount related to the maintenance of communication with the processing circuitry is connected, and therefore the battery can be suppressed.

在本发明中,连接维持程序执行将预先设定的请求时间向通信中继装置发送的功能,通信中继装置具有从回路连接后的通信终端装置接收请求时间的功能;在该通信终端装置的无通信期间到达请求时间时、切断该通信终端装置的回路的功能;以及对该通信终端装置将请求时间作为切断时间进行广播、以代替上述规定时间的功能。 In the present invention, connection maintenance function program execution request for a preset time to send the communication relay apparatus, a communication relay device having received the request time from the communication terminal apparatus connected to the circuit function; in the communication terminal apparatus no communication request for the arrival time period, the circuit cut-off function of the communication terminal apparatus; and a request to the communication terminal apparatus as a cutoff time broadcast time to replace the function of the predetermined time. 这里,实施形态中所示的第2及第3方式请求时间相当于上述请求时间。 Here, the second and third embodiment illustrated embodiment corresponds to the time of request the request time. 通过上述那样,由于在通信中继装置中能够根据请求时间进行回路切断的控制,在通信终端装置中能够根据请求时间进行空分组的发送时刻的控制等,因此能够在现在的方式中进行更适合的处理。 Since the control circuit can be cut according to a request in time communication relay apparatus, the transmission time can be controlled according to a request of the null packet time in the communication terminal apparatus and the like, can be present in a more appropriate manner by the above processing. 例如,通过设定请求时间的值比上述规定时间要长,能够进一步减少例如空分组的发送次数。 For example, by setting the value of the request time is longer than the predetermined time, for example, possible to further reduce the number of null packets transmitted.

在第2发明中,在通信终端装置与通信中继装置进行通信的网络系统中,通信中继装置具有在回路连接后的通信终端装置的无通信期间到达规定时间时、切断该通信终端装置的回路的功能;以及将上述规定时间作为切断时间定期广播的功能。 In the second invention, a communication terminal apparatus in a network system with the communication relay apparatus of a communication, the communication relay apparatus having no communication during the communication terminal apparatus reaches a predetermined time of circuit connection, disconnection of the communication terminal apparatus function circuit; and will cut the predetermined time period as a time to regularly broadcast function. 然后,通信终端装置根据广播的切断时间,进行维持回路连接用的处理。 Then, the communication terminal apparatus according to the broadcast time of cutting, the processing circuit to maintain the connection.

这里,实施形态中所示的终端装置相当于上述通信终端装置,实施形态中所示的接入点相当于通信中继装置,实施形态中所示的缺省切断时间相当于规定时间。 Here, the terminal apparatus shown embodiment corresponds to the communication terminal apparatus, the access point illustrated embodiment corresponds to the communication relay means, illustrated embodiment, the default cut-off time corresponding to a predetermined time. 另外,第2发明不需要如第1发明那样,应用程序的类型的优先级与维持回路连接用的方式相对应。 Further, as the second invention does not require that the first invention, and sustain priority application type corresponding to the loop connection. 如上所述,由于根据广播的切断时间来进行维持前述回路连接用的处理(例如,根据广播的切断时间及自己的无通信期间,来发送空分组,使得维持回路连接用的空分组的发送次数减少),因此能够减少维持回路连接用的通信量(例如,空分组的发送量),能够提高网络系统的性能。 As described above, since the processing circuit to maintain the connection according to the cutting time of the broadcast (e.g., during the off time according to his broadcast and non-communication, transmits a null packet, so that the number of null packet transmission circuit connected to maintain the reduced), the amount can be reduced to maintain the communication with the circuit connection (e.g., a null packet transmission amount) can improve the performance of the network system. 再有,由于利用通信中继装置来广播切断时间,因此即使多个通信终端装置不要求各自通信中继装置发送切断时间,也能够在通信终端装置中根据广播的切断时间进行维持回路连接用的处理(例如,发送空分组),能够减少与该处理有关的通信量。 Further, since the communication relay apparatus broadcasts off time, even if a plurality of communication terminal apparatuses is not required to cut each time a communication relay device, can be connected to a sustain circuit in accordance with the disconnection time of the broadcast communication terminal apparatus processing (e.g., transmitting a null packet), it is possible to reduce the traffic associated with the process. 再有,在通信终端装置是用电池动作的便携式终端时,由于减少与维持回路连接用的处理有关的通信量,因此也能够抑制电池的消耗。 Further, consumption of the communication terminal apparatus is a portable terminal battery operation, due to the reduced amount related to the maintenance of communication with the processing circuitry is connected, and therefore the battery can be suppressed.

在第3发明中,服务器具有单一或多个应用程序,通信终端装置具有与服务器的应用程序进行应用间通信的单一或多个应用程序,在将上述服务器与上述通信终端装置通过通信中继装置进行连接的网络系统的通信中继装置中,具有在回路连接后的通信终端装置的无通信期间到达规定时间时、切断该通信终端装置的回路的功能;以及将上述规定时间作为切断时间定期广播的功能。 In the third invention, a single server or a plurality of application programs, the communication terminal apparatus having a single or a plurality of inter-application communication applications with the application server, when said server apparatus with the communication terminal through the communication relay apparatus the communication relay device for connection of a network system having no time during the communication with the communication terminal apparatus after a predetermined time of arrival of the circuit connection, disconnection of the communication terminal apparatus function circuit; and the predetermined period of time periodically broadcast as a cutting function.

这里,实施形态中所示的终端装置相当于上述通信终端装置,实施形态中所示的接入点相当于通信中继装置,实施形态中所示的缺省切断时间相当于规定时间。 Here, the terminal apparatus shown embodiment corresponds to the communication terminal apparatus, the access point illustrated embodiment corresponds to the communication relay means, illustrated embodiment, the default cut-off time corresponding to a predetermined time. 另外,由于应用程序的类型的优先级与维持回路连接用的方式相对应,因此可将类型的优先级称为是维持回路连接用的方式的优先级。 Further, since the priority and sustain the type of application corresponding to a circuit connection, and thus may be referred to as a type of priority is to maintain the loop mode connection to the priority. 通过上述那样,能够提供第1发明中使用的通信终端装置。 As the above, it is possible to provide a communication terminal apparatus used in the first invention.

在第5发明中,服务器具有单一或多个应用程序,通信终端装置具有与服务器的应用程序进行应用间通信的单一或多个应用程序,通信中继装置具有在回路连接后的通信终端装置的无通信期间到达规定时间时、切断该通信终端装置的回路的功能;以及将上述规定时间作为切断时间定期广播的功能,在将上述服务器与上述通信终端装置通过上述通信中继装置进行连接的网络系统的通信终端装置所用的程序中,具有根据起动的单一或多个应用程序的类型的优先级,决定与应用程序的类型相对应的维持回路连接用的方式,并根据广播的切断时间来进行该决定的方式的连接维持程序。 In the fifth invention, a single server or a plurality of application programs, the communication terminal apparatus having a single or a plurality of inter-application communication applications with the application server, the communication relay device has a communication terminal apparatus after the circuit connection when the non-communication period reaches the predetermined time, the circuit cut-off function of the communication terminal apparatus; and the predetermined period of time periodically broadcast as a function of cutting, in the above-described server apparatus with the communication terminal connected via the network communication relay apparatus program communication terminal apparatus system is used having the type of type of starting a single or a plurality of application priority, determined with the application mode circuit connected to the corresponding maintained and carried out according to the cutting time of the broadcast of connection of the decision to maintain the program.

这里,实施形态中所示的终端装置相当于上述通信终端装置,实施形态中所示的接入点相当于通信中继装置,实施形态中所示的缺省切断时间相当于规定时间。 Here, the terminal apparatus shown embodiment corresponds to the communication terminal apparatus, the access point illustrated embodiment corresponds to the communication relay means, illustrated embodiment, the default cut-off time corresponding to a predetermined time. 另外,由于应用程序的类型的优先级与维持回路连接用的方式相对应,因此可将类型的优先级称为是维持回路连接用的方式的优先级。 Further, since the priority and sustain the type of application corresponding to a circuit connection, and thus may be referred to as a type of priority is to maintain the loop mode connection to the priority. 通过上述那样,能够提供第1发明中使用的通信终端装置用的程序。 As the above, it is possible to provide a communication terminal used in the first invention of the apparatus with a program.

另外,在第5发明中,具有操作禁止控制程序,该操作禁止控制程序执行检测及预测回路状态是否良好的功能;根据检测及预测的结果禁止对前述应用程序的操作或解除操作禁止的功能;以及利用特定的操作来解除操作禁止的功能。 Further, in the fifth invention, having the operation prohibition control routine, the operation prohibition control routine executed detection and prediction circuit is in good function; inhibit operation of the application or the releasing operation prevention function according to the result of the detection and prediction; and the use of specific actions to prohibit the release operation function. 这里,实施形态中所示的回路状态监视程序及操作禁止程序相当于上述的操作禁止控制程序。 Here, the loop status monitor and the operation prohibition procedure shown embodiment corresponds to the above-described operation prohibition control routine. 另外,所谓特定的操作,是用鼠标点击实施形态中所示的解除按钮等操作。 Further, a so-called specific operation, release button or the like clicking operation shown embodiment with the mouse. 通过这样,在回路状态不好时或预测回路状态恶化时,由于禁止操作鼠标及键盘,不能利用通信终端装置的应用程序进行服务器的文件更新,因此能够防止发生服务器的文件损坏等问题。 By this way, when the prediction circuit, or in a bad state deteriorates circuit state, by disabling the keyboard and mouse operation, the application can not use a communication terminal apparatus performs update file server, the file can be prevented the occurrence of problems such as damage to the server. 另外,由于能够利用特定的操作来解除操作禁止,因此能够根据用户的判断对应用程序进行操作。 Further, since it is possible to use a particular operation prohibition releasing operation, it is possible to operate the application based on the user's judgment.

根据本发明,由于与维持回路连接用的方式相对应的应用程序的类型及类型的优先级不是由通信中继装置决定,而是由通信终端装置决定,因此能够考虑到应用程序的种类及使用状况来进行最佳的维持回路连接用的处理。 According to the present invention, due to the type and the type is not determined by the priority of the communication relay device connected to the loop to maintain a manner corresponding to the application, but rather is determined by the communication terminal apparatus, it is possible to take into account the kind and application conditions to maintain optimal processing circuits are connected with.

图4所示为在终端装置1中对回路的连接维持进行管理用的数据。 Figure 4 shows the connection of the circuit used to maintain data management apparatus 1 in the terminal. APP类型表41、余量时间42、第2方式请求时间43、以及第3方式请求时间44,是由网络管理者对控制单元11预先设定的数据。 APP type table 41, the balance 42 times, 43 times a second mode request, and a third mode request time 44, the control unit 11 is data pre-set by a network administrator. 空分组剩余时间45及广播接收值46是存储在控制单元11的能够读/写的存储区(未图示)的数据。 NULL packets remaining time value 45 and 46 receiving the broadcast data is stored in the memory area can be read / write control unit 11 (not shown). 以下说明各数据。 The following description of each data. APP类型表41是对于每个维持回路连接用的方式登录应用程序24的识别信息的表。 APP is a type table 41 for the login application circuit connected to each sustain embodiment of the identification information table 24. 这里,APP24a、24b作为第1类型进行登录,APP24c、24d作为第2类型进行登录,APP24e、24f作为第3类型进行登录。 Here, APP24a, 24b as the first type of log, APP24c, 24d log, APP24e as the second type, 24f registered as the third type.

在第1~第3类型的应用程序24的动作中,分别采用第1~第3方式。 In the operation of the first to third types of applications 24, respectively of the first to third embodiment. 即,使应用程序24的类型与维持回路连接用的方式相对应。 That is, the type of application and sustain circuit 24 is connected with the corresponding. 三个类型中有优先级,第1类型的优先级最低,第3类型的优先级最高。 There are three types of priority highest priority, the first priority of the lowest type, 3 type. 因而,在第2类型的程序与第3类型的程序同时动作中时,采用第3方式,在第1类型的程序与第2类型的程序同时动作中时,采用第2方式。 Thus, the program with the program of the third type when the second type of simultaneous operation, using the third embodiment, the second type of program and the second program of the first type of operation simultaneously, using the second embodiment. 另外,各终端装置1不一定安装相同的应用程序24,有的安装了全部的第1类型~第3类型,也有的只安装了第2类型。 In addition, each terminal apparatus 1 need not install the same application 24, all of the installed some type first to third types, and some of the second type just installed. 这里,设应用程序24的类型的数量及维持回路连接用的方式为3个,但没有理由只限定于3个,也可以是1个、2个、4个或大于等于4个。 Here, the number of types of embodiment is provided with the application and the sustain circuit 24 is connected to three, but there is no reason to be limited only to three, but may be one, two, four, or four or greater.

第1方式是不发送维持回路连接用的分组(以下称为空分组)的方式。 The first embodiment does not transmit a packet circuit connected to maintain the embodiment (hereinafter, referred to as an empty packet). 该方式虽然在进行回路连接维持这一点上不太好,但是不产生因发送空分组而增加的通信量。 While the circuit connection is performed in this way to maintain this point is not very good, but no traffic is generated by sending null packets increases. 第2方式是无通信期间在到达上述的切断时间之前、从终端装置1发送空分组的方式。 The second embodiment is a non-communication period prior to said cutting time is reached, send a null packet from the terminal apparatus 1. 通过这样发送空分组,防止在不发送APP分组时接入点2切断回路。 By transmitting a null packet, cut off the circuit to prevent the access point 2 is not transmitted when the APP packet. 该方式也是发送维持回路连接用的所必需的最低限度的空分组的方式。 This embodiment mode is also connected to a minimum circuit necessary for maintaining an empty packet is transmitted. 第3方式是无通信期间若持续一定时间、则发送空分组的方式。 If the third embodiment is for a certain time during which no communication, transmitting a null packet mode. 作为上述一定时间,由于使用比切断时间足够短的值(这里设为1秒),因此在不发送APP分组时以1秒间隔发送空分组。 As the above-mentioned predetermined time, the use time is sufficiently shorter than the cutoff value (here set to one second), and therefore is not transmitted APP packet null packet transmission at 1 second intervals. 这里说明了三种方式的简要动作,但也可以采用不同于上述说明的方式。 Described briefly here three ways of operation, but is different from the embodiment described above may be employed.

各应用程序24的类型因应用程序24本身的通信动作的多少或回路的切断所受到影响的程度,考虑到应用程序24的使用状况等,由网络管理者决定。 The extent of each type of application 24 itself due to disconnection of communication actions or how many circuit applications 24 are affected, taking into account the status of use of the application 24, determined by the network administrator. 例如,对于即使切断回路但弊病也比较少的应用程序24,则决定为第1类型。 For example, even when cut off the circuit for the shortcomings but also less application 24, determined as the first type. 对于若切断回路则弊病大的应用程序24,则决定为第2类型。 If you cut off the circuit for the ills of large applications 24, the decision is the second type. 对于VoIP的应用程序24,则决定为第3类型。 For VoIP applications 24, has decided for the first 3 types. 使用VoIP的终端装置1多数在移动中。 VoIP terminal apparatus using a majority of the move. 在第2方式中,若在通信状态恶劣时发送空分组,则有可能空分组不被接入点2接收,回路切断。 In the second embodiment, when transmitting a null packet when the communication condition is poor, it is possible empty packets are not receiving access point 2, the circuit cut off. 另外,由于用VoIP进行无声压缩,因此在无声时APP分组中断,但即使短时间切断,用户也为难。 In addition, as a result of silent compression with VoIP, so when silent APP packet interrupt, but even a short cut, but also difficult for the user. 根据以上的理由,对于VoIP的应用程序24,则决定为第3类型。 For these reasons, for VoIP applications 24, has decided for the first 3 types.

余量时间42是在第2方式中为了使空分组的发送时间相对于切断时间具有余量而使用的。 42 is a time margin in the second embodiment to the transmission time with respect to the cutting null packet having a margin time of use. 例如,在切断时间是10秒、余量时间42是2秒时,若无通信期间为8秒(10秒-2秒),则上述的连接维持程序21发送空分组。 For example, in the cutting time is 10 seconds, the time margin 42 is 2 seconds, during the absence of communication of 8 seconds (10 seconds to 2 seconds), the above-described connector 21 maintains the program transmits a null packet. 之所以这样做,是因为尽管发送了空分组,但有时由于传送延迟等,在切断时间内接入点2不能接收空分组,回路被切断。 Did so because although the transmission of null packets, but sometimes due to transmission delay or the like, in the off time the access point 2 can not receive the NULL packets, the circuit is cut off. 以下,设余量时间42为2秒进行说明。 Hereinafter, the margin time set to 2 seconds 42 will be described.

第2方式请求时间43是在采用第2方式时请求用作为切断时间(以下称为切断时间的变更请求)、以代替接入点2广播的缺省的切断时间的时间。 The second embodiment 43 is the request time when a request using the second embodiment is used as a cutoff time (hereinafter referred to as the off time change request), the access point 2 in place of the default broadcast time cutoff time. 该第2方式请求时间43由于是为了减少空分组的发送次数而使用的,因此比缺省的切断时间要长。 The second embodiment 43 since the request time is transmitted to reduce the number of null packets are used, so the cut than the default time longer. 以下设缺省的切断时间为10秒,第2方式请求时间43为20秒,来进行说明。 The following default set-off time is 10 seconds, the second mode request time is 43 to 20 seconds, will be described. 若第2方式请求时间43发送给接入点2,接入点2(正确来说是控制程序34)接受切断时间的变更请求,则从下一次的广播开始,广播第2方式请求时间43,代替接入点2中设定的缺省的切断时间。 When the second embodiment 43 time request to the access point 2, the access point 2 (a control program is correct 34) accepts the change request-off time, from the start the next broadcast, the broadcast time 43 requests the second embodiment, Instead of cutting off the access point default time set 2.

第3方式请求时间44是在采用第3方式时请求用作为切断时间、以代替接入点2广播的缺省的切断时间的时间。 44 the third embodiment is a request by request time as the cutting time when using the third embodiment, the access point 2 in place of the default time cutoff time broadcast. 该第3方式请求时间44由于也是为了不使与接入点2进行回路连接的终端装置1的台数增大而使用的,因此比缺省的切断时间要短。 The third embodiment 44 since the request time is not to make the access point 2 and a terminal device connected to the circuit 1 increases the number of use, so shorter than the default shutdown time. 例如,若使用VoIP的多个终端装置1尽管不发送APP分组或空分组,仍长时间与回路连接,则产生的问题是,接入点2一侧的管理终端装置1的表格大小要增大,存储器区不够,或者通信能力降低。 For example, when using a plurality of terminal devices while not transmitting the VoIP packets or APP null packet still connected to the long loop, problems are produced that the size of the table management terminal apparatus 2 side of the access point 1 to be increased , the memory area is insufficient, or reduce communication capabilities. 为了不产生该问题,设第3方式请求时间44为比缺省的切断时间要短的时间。 Not to cause this problem, the third embodiment is provided than the default request time 44 times shorter cutting time. 以下,设第3方式请求时间44为5秒来进行说明。 Hereinafter, the third embodiment is provided request time is 5 seconds to 44 will be described. 利用第3方式请求时间44进行的切断时间的变更请求、接受及广播与第2方式请求时间43的情况同样进行。 Off time of change request by the third embodiment 44 of the request time, and a broadcast receiving mode and the second request for the same time (43).

空分组剩余时间45是第2或第3方式中使用的、发送空分组之前的剩余时间。 The remaining 45 empty packet is a second time or the third embodiment are used, and the time remaining before the null packets. 空分组剩余时间45在第2方式中以{广播的切断时间-余量时间42}进行初始化,在第3方式中以1秒进行初始化。 NULL packets remaining time in the second embodiment 45 to cut off the time of the broadcast of {- 42} to initialize margin time, in the third embodiment is initialized to 1 second. 然后,每隔一定时间进行减法计数,若空分组剩余时间45变为0,则发送空分组。 Then, at regular intervals subtraction counting, the remaining time when the empty packet 45 becomes 0, the empty packet is transmitted. 另外,初始化是在发送APP分组或空分组时等情况下进行。 Further, when the initialization is sending packets or APP null packet for a case where the like. 广播接收值46是将广播的切断时间写入存储区的值,是缺省的切断时间、第2方式请求时间43或第3方式请求时间44的某一个值。 The broadcast receiving cut value 46 is the value of time of the broadcast storage area is written, is the default shutdown time, the second time 43 mode request or a request from a third embodiment 44 of the value of the time.

图5所示为在接入点2中为了管理回路的连接及切断而使用的数据。 Figure 5 shows the data in the access point 2 in order to manage the connection and disconnection of the circuit used. 缺省切断时间47是由网络管理者在控制单元31中预先设定的数据,是在无通信状态继续时一直到切断回路之前的缺省时间、即上述的[缺省的切断时间(10秒)]。 47 is a default shutdown time data by a network manager unit 31 set in advance before the default time of cutting loop control, in non-communication state continues until, i.e. above the [default cutoff time (10 seconds )].

终端装置管理表48是管理回路连接后的终端装置1的状态用的表,包括终端ID48a、切断剩余时间48b、请求有无接受48c、类型号48d、以及请求时间48e。 The terminal device management table 48 is a circuit connected to the terminal management apparatus 1 is used in the state table, including a terminal ID48a, cut the remaining time 48b, 48c to accept the request for the presence or absence, type number 48d, and a request time 48e. 终端ID48a是识别终端装置1用的信息。 ID48a terminal information for identifying the terminal apparatus 1 is used. 这里作为终端ID48a用3位数字表示,但可使用MAC地址等。 Here represented by the three-digit number as a terminal ID48a, but can use the MAC address or the like. 切断剩余时间48b是在无通信状态继续时一直到切断回路之前的剩余时间,每隔一定时间进行减法计数,若利用减法计数使切断剩余时间48b变为0,则控制程序34切断该终端装置1的回路。 48b is cut off the remaining time until the communication state in the absence of the time remaining before the cutting loop continues, the count subtraction intervals, if the count of the cutting subtractor 48b remaining time becomes zero, the control program 34 to disconnect the terminal apparatus 1 circuit. 另外,若接收APP分组或空分组,则发送源的终端装置1的切断剩余时间48b用后述的初始值进行初始化。 Further, if the received packet or APP null packet, the transmission source terminal device 1 48b remaining time the cutting initialized at a value to be described later.

请求有无接受48c表示是否接受上述的切断时间的变更请求,对于接受的终端装置1,为[有],对于拒绝的终端装置1,为[无]。 Have 48c indicating whether to accept a request to accept a change request of the above-mentioned breaking time for the receiving terminal apparatus 1, is [there], to reject the terminal apparatus 1, is [no]. 另外,在回路连接时,设定为[无]。 Further, when the circuit connection is set to [NO]. 关于是否接受变更请求的决定方法将在后面叙述。 Method of determining whether to accept the change request will be described later. 类型号48d是在切断时间变更请求时与第2或第3方式请求时间43或44一起接收的应用程序24的类型号(表示第2或第3类型的[2]或[3]),在决定是否接受变更请求时使用。 Type number 48d in the off time of the second or the third mode request time 43 or application 44 received with the type of number 24 when the change request (represented by the second or the third type of [2] or [3]), in decide whether to accept change requests. 请求时间48e是在切断时间变更请求时接收的第2或第3方式请求时间43或44的某一个请求时间。 48e is a second request time or the third embodiment when the received change request at a request time cutoff time a request time 43 or 44. 因而,切断剩余时间48b的初始值在请求有无接受48c为[有]时,是请求时间48e,在请求有无接受48c为[无]时,是缺省切断时间47。 Accordingly, when the initial value of the remaining time the cutting 48b, 48c to accept the request for the presence or absence of [there], a request time 48e, 48c to accept the request for the presence or absence of [No], 47 is the default shutdown time.

图6所示为接入点2广播的广播分组B。 Figure 6 shows the access point 2 broadcasts a broadcast packet B. 该广播分组B包括对于接受切断时间的变更请求的终端装置1的数据即请求接受部分、以及对于拒绝变更请求的终端装置1和没有进行变更请求的终端装置1的数据即缺省部分。 The broadcast packet B comprises means for receiving a terminal change request-off time, i.e., a data request accepting portion i.e. the default data portion, and to reject a change request of the terminal device and the terminal device no change request 1. 缺省部分的NUL代码是表示缺省部分的信号,该缺省切断时间与图5所示的缺省切断时间47相等。 The default NUL code is the default portion is a signal portion, the default cut default time shown in FIG. 5 off time is equal to 47. 请求接受部分的每个终端装置1的终端ID及请求时间与终端装置管理表48的终端ID48a及请求时间48e相等。 Request accepting terminal portion of each terminal device ID 1 and a request time and the terminal device management table of the terminal 48 and the request time ID48a 48e are equal. 因而,若从接收了广播分组B的终端装置1来看,若广播分组B中没有包含有自己的终端ID,则缺省切断时间成为广播的切断时间。 Accordingly, when a broadcast packet received from the terminal B of the view of apparatus 1, when the broadcast packet B does not contain its own terminal ID, the time becomes the default cut-off time of the broadcast. 另外,在本实施形态中,若接受全部的切断时间的变更请求,则由于广播分组B的大小增大,广播时间延长,因此对于接受变更请求的终端装置1的台数设定上限值。 Further, in the present embodiment, if the change was accepted all cutting time, due to the increased size of the broadcast packet B, the broadcast time is extended, and therefore the terminal for receiving the change request means the upper limit of the number of set 1.

图7为表示终端装置1及接入点2的动作的时序图。 7 is a terminal device 1 and the timing chart of operation of the access point 2. 以下,参照流程图说明终端装置1及接入点2的动作的一个例子。 Hereinafter, with reference to a flow chart illustrating an example of the operation of the apparatus 1 and the terminal 2 of the access point. 接入点2以一定的广播周期(在本实施形态中设定为2秒)将广播分组B进行广播。 The access point 2 broadcasts a certain period (set to two seconds in the present embodiment) the broadcast packets B broadcasts. 应用程序24按照APP24a、APP24c、APP24e的顺序起动,按照APP24e、APP24c、APP24a的顺序结束。 Application 24 in order APP24a, APP24c, APP24e start, end in order APP24e, APP24c, APP24a of. 该APP24a、APP24c、APP24e分别是第1、第2、第3类型的应用程序24(参照图4)。 The APP24a, APP24c, APP24e respectively, the first, second, and third type of application 24 (see FIG. 4). 即使在APP24a起动前,接入点2也随时发出信标电波,通过终端装置1进行应答,与应答的终端装置1的回路进行连接。 Even in APP24a before starting the access point 2 on any emitted radio beacon, the terminal apparatus 1 responds to the request, the response of the circuit is connected to the terminal apparatus 1. 也可以在连接时,接入点2或服务器3对终端装置1进行认证,仅在正规进行认证时连接回路。 It may be the connection, the access point 2 or the server 3 authenticates the terminal device 1, the circuit is connected only when the normal authentication. 回路连接后的终端装置1将广播分组B中的切断时间的数据作为广播接收值46加以保存。 The terminal apparatus 1 to cut the time of broadcast packet data B is to be stored as the value of the broadcast reception circuit 46 after the connection. 但是,由于应用程序24一个动作也不进行,从终端装置1既不发送APP分组,也不发送空分组,因此回路连接之后,若经过缺省切断时间47,则回路将切断。 However, because the application 24 does not perform an action, an APP packet is neither transmitted nor empty packet transmitted from the terminal device, so after circuit connection, if the elapsed time is the default cut 47, the cut loop.

首先,若起动APP24a,则从终端装置1发送连接请求分组(未图示),从而连接回路。 First, when starting APP24a, from the terminal apparatus 1 transmits a connection request packet (not shown), thereby connecting the loop. 在该时刻,由于APP24a是第1类型,因此采用第1方式作为回路连接维持方式。 At this time, since APP24a is a first type, so the use of the first embodiment as a way to maintain the circuit connection. 在第1方式中,由于不发送空分组,因此若无通信期间超过缺省切断时间47,则回路被切断。 In the first embodiment, since the null packet is not transmitted, and therefore the absence of communication over the default shutdown time period 47, the loop is cut off. 这里,假设APP24适当发送APP分组(未图示),回路不被切断。 Here, it is assumed APP24 suitable APP packet transmission (not shown), the circuit is not cut.

然后,若起动优先级高于APP24a的第2类型的APP24c,则采用第2方式。 Then, when the run priority than the second type APP24c APP24a, the second embodiment is used. 在第2方式中,若无通信期间成为{广播接收值46-余量时间42}(这时刻的广播接收值46是广播分组B1中的缺省切断时间),则从终端装置1发送空分组,防止回路切断。 In the second embodiment, a period in the absence of a communication broadcast receiving values ​​{46- 42} margin time (time of the broadcast receiving this value is the default broadcast packet 46 in B1-off time), from the terminal apparatus 1 transmits a null packet prevent circuit cut off. 另外,在APP24c起动时,为了进行切断时间的变更请求,从终端装置1发送包含第2方式请求时间43及类型号([2])的变更请求分组。 Further changes, when starting APP24c, to cut the time change request, from the terminal apparatus 1 transmits the second embodiment comprises a request time and type number 43 ([2]) request packet. 在接收了变更请求分组的接入点2中,决定是否接受变更请求。 In the change request packet is received the access point 2, to decide whether to accept the change request. 这里,假设接受变更请求。 Here, assuming that the change was accepted. 其结果在广播分组B2~B3中,对该终端装置1广播第2方式请求时间43作为切断时间。 As a result, the broadcast packet B2 ~ B3, the terminal apparatus broadcasts the second embodiment 43 as a request time cutoff time. 因而,在该时刻以后,若无通信期间成为{第2方式请求时间43-余量时间42},则发送空分组。 Accordingly, after this point of time, a period in the absence of a second communication mode request time {43 42} margin time, send a null packet.

然后,若起动优先级高于APP24c的第3类型的APP24e,则采用第3方式。 Then, if the priority is higher than the start of the third type APP24c APP24e, the third embodiment is used. 在第3方式中,若无通信期间成为1秒,则从终端装置1发送空分组,防止回路切断。 In the third embodiment, if no communication has become one second period, from the terminal apparatus 1 transmits a null packet, to prevent the cutting loop. 该时刻的广播接收值46是取决于广播分组B3的值,是第2方式请求时间43。 The broadcast receiving time of the value of 46 is dependent on the value of the broadcast packet B3, the second embodiment is the request time 43. 另外,在APP24e起动时,为了进行切断时间的变更请求,从终端装置1发送包含第3方式请求时间44及类型号([3])的变更请求分组。 Further changes, when starting APP24e, to cut the time change request, from the terminal apparatus 1 transmits the third embodiment comprises a request time and type number 44 ([3]) request packet. 在接收了变更请求分组的接入点2中,决定是否接受变更请求。 In the change request packet is received the access point 2, to decide whether to accept the change request. 这里,也假设接受变更请求。 Here, it is assumed that the change was accepted. 其结果在广播分组B4~B5中,对该终端装置1广播第3方式请求时间44作为切断时间。 As a result, the broadcast packet B4 ~ B5, a broadcast to the terminal apparatus 1 of the third embodiment 44 as a request time cutoff time.

然后,若第3类型的APP24e结束,则采用第2方式。 Then, if the third type APP24e end, the second embodiment is used. 即使这里为了也进行切断时间的变更请求,发送包含第2方式请求时间43及类型号([2])的变更请求分组。 Even here also in order to change the cutting time request, the second embodiment transmits a request time and the type of number 43 ([2]) of the change request packet. 这里,也假设接受变更请求。 Here, it is assumed that the change was accepted. 其结果在B6以后的广播分组中,对该终端装置1广播第2方式请求时间43作为切断时间。 As a result, in the subsequent B6 broadcast packet, a broadcast to the terminal apparatus 1 of the second embodiment 43 as a request time cutoff time. 然后,若第2类型的APP24c结束,则采用第1方式。 Then, when the second type APP24c end, the first embodiment is used. 在第1方式中,在终端装置1一侧,由于不进行连接维持用的控制,因此不发送变更请求分组。 In the first embodiment, the terminal device 1 side, since no connection is used to maintain control, and therefore does not send the change request packet. 但是,也可以发送也可以用缺省切断时间47作为切断时间的内容的通知,来代替变更请求分组。 However, it may also be transmitted using the default cut-off time 47 as the notification time of the content, instead of changing the request packet. 然后,若APP24a结束,无通信期间到达第2方式请求时间43,则接入点2切断终端装置1的回路。 Then, if APP24a end, the time the request reaches the second embodiment 43, the access point 2 the loop without cutting the terminal apparatus 1 during communication.

图8及图9是表示终端装置1的动作、即连接维持程序21的动作的流程图。 8 and FIG. 9 is a diagram showing the operation of the terminal apparatus 1 is a flowchart of the operation program 21 is maintained, i.e. the connection. 连接维持程序21随时监视以下的事件、即应用程序24的起动及结束、广播分组B的接收、每隔一定时间发生的定时器信号、以及利用应用程序24的分组(APP分组)发送,若检测出发生了事件,则进行与事件相应的处理。 Monitor event at any time following connection maintenance program 21, i.e., the start and end of the application 24, receives the broadcast packet B, the timer signal at regular intervals occur, and packets (APP packets) sent using the application 24, if the detection the occurrence of an event, the corresponding event processing is performed. 另外,为了使事件发生,或进行检测,连接维持程序21向OS25发出命令,或者参照OS25管理的信息。 Further, in order to make the event, or detection, connection maintenance program 21 issues a command to OS25, OS25, or reference information management. 例如,应用程序24的起动及结束是通过参照OS25管理下的活动任务表来进行检测的。 For example, the start and end of the application 24 is detected by referring to the task table at the active management OS25.

首先,说明连接维持程序21在检测到应用程序24重新起动时的动作。 First, the operation when an application program 24 is restarted to maintain the connector 21 is detected. 在没有回路连接时(图8的S10:Y),连接维持程序21发送连接请求分组(S11)。 When there is no circuit connection (S10 of FIG. 8: Y), the program to maintain the connection 21 transmits a connection request packet (S11). 若接入点2接收该连接请求分组,则回路连接。 If the access point 2 receives the connection request packet, the loop connection. 实际上,虽然是连接维持程序21生成连接请求分组,并通过OS25接受了连接请求分组的无线通信驱动程序发送连接请求分组,但这里假设是连接维持程序21发送连接请求分组。 Indeed, while maintaining a connection program 21 generates a connection request packet received by the wireless communication OS25 driver connection request packet transmits a connection request packet, it is assumed here that the transmission 21 is connected to a program to maintain the connection request packet. 关于这一点,对于变更请求分组等也同样。 On this point, the request packet and so also for change.

在该时刻,在优先级最高的第3方式的应用程序24在这之前就动作时(S12:Y),由于已经采用第3方式,不需要改变方式,因此处理结束。 At this time, when the application of the highest priority of the third embodiment 24 before this operation (S12: Y), since the third embodiment has been adopted, no need to change mode, the processing ends. 另外,在这之前优先级最高的第3类型的应用程序24不动作、而且新起动的应用程序24是第3类型时(S12:N、而且S13:Y),采用第3方式,(S14),向接入点2发送包含第3方式请求时间44及应用程序24的类型号([3])的变更请求分组(S15)。 Further, in the highest priority to a third type of application 24 does not operate before, and the new start of the application 24 is the third type (S12: N, and S13: Y), using the third embodiment, (S14) , the third embodiment transmits a request time type applications 44 and 24 to the access point 2 ([3]) of the change request packet (S15). 再有,空分组剩余时间45以1秒进行初始化(S16)。 Further, 45 empty packets remaining time of 1 second is initialized (S16).

在S13中,在判定为新起动的应用程序24不是第3方式(S13:N)、而且第2类型的应用程序24在这之前就动作时(S17:Y),由于不需要变更现在的方式即第2方式,因此处理结束。 In S13, it is determined that the new application is not the start of the third embodiment 24 (S13: N), and the second type of application 24 during operation before this (S17: Y), there is no need to change the current mode i.e. the second embodiment, the process ends. 另外,第2类型的应用程序24在这之前不动作的情况下(S17:N),新起动的应用程序24是第2类型时(S18:Y),采用第2方式,(S19),向接入点2发送包含第2方式请求时间43及类型号([2])的变更请求分组(S20)。 Further, the second type of application 24 before that without operation (S17: N), the new start of the application 24 is the second type (S18: Y), using the second embodiment, (S19), the the access point 2 transmits a second type of embodiment No. 43 and the request time ([2]) of the change request packet (S20). 再有,空分组剩余时间45以{广播接收值46-余量时间42}进行初始化(S21)。 Further, null packets remaining time value 45 to the broadcast receiving {46- 42} margin time is initialized (S21). 另外,在新起动的应用程序24不是第2类型时(S18:N),即是第1类型时,采用第1方式(S22)。 Further, when a new application 24 is not the start of the second type (S18: N), that is, when the first type, using a first embodiment (S22).

下面,说明连接维持程序21检测到应用程序24结束时的动作。 Next, the program 21 detects a connection is maintained during the operation of the application 24 ends. 在即使某应用程序24结束、但优先级最高的第3类型的应用程序24在动作中时(图9的S40:Y),由于不需要变更现在的方式即第3方式,因此处理结束。 Even in an application end 24, 24 but when the operation of the third highest priority type of application (S40 of FIG. 9: Y), there is no need to change the current mode that is the third embodiment, the process ends. 下面叙述第3类型的应用程序24不是在动作中(S40:N)、而且结束的应用程序24是第3类型时(S41:Y)的情况。 The following describes the third type of application 24 not in operation (S40: N), and the end of the application 24 is a Type 3: the case (S41 Y) is. 在这种情况下,若第2类型的应用程序24是在动作中(S42:Y),则由于第2类型的优先级成为最高,因此采用第2方式(S43),向接入点2发送包含第2方式请求时间43及类型号([2])的变更请求分组(S44)。 In this case, when the type of the second application 24 is in operation (S42: Y), since the priority of the highest of the second type, so a second embodiment (S43,), transmits to the access point 2 2 embodiment includes a first request type and number 43 the time ([2]) of the change request packet (S44). 再有,空分组剩余时间45进行初始化(S45)。 Further, null packets 45 initializes the remaining time (S45). 与上不同的是,若第2类型的应用程序24不是在动作中(S42:N),则与第1类型的应用程序24是否是在动作中无关,采用第1方式(S46)。 And the difference is that when the second type of application 24 not in operation:, 24 is independent of whether the operation is the first type of application (S42 N), using a first embodiment (S46). 这是由于,在第1方式中,为了回路连接维持,并不进行特别处理。 This is because, in the first embodiment, in order to maintain the circuit connection, no special treatment.

另外,在第3类型的应用程序24不是在动作中(S40:N)、而且结束的应用程序24不是第3类型时(S41:N),若第2类型的应用程序24是在动作中(S47:Y),则维持现在的方式即第2方式。 Further, in the third type of application 24 not in operation (S40: N), and at the end of the application 24 is not the third type (S41: N), when the second type of application 24 is in operation ( S47: Y), the current mode is maintained i.e. the second embodiment. 与上不同的是,若第2类型的应用程序24不是在动作中(S47:N),则采用第1方式(S48)。 And the difference is that when the second type of application 24 not in operation (S47: N), the use of the first embodiment (S48). 在上述的说明中,在采用的方式从第3方式变为第1方式时,以及从第2方式变为第1方式时,从终端装置1不向接入点2发出任何通知,但也可以通知该方式的变化,在接入点2使用缺省切断时间47作为切断时间。 In the above description, when employed in the embodiment from the third embodiment becomes the first embodiment and the second embodiment from the first embodiment becomes, from the terminal apparatus 1 does not send any notification to the access point 2, it may be the mode change notification, the access point 2 using the default cut-off time as 47 times.

下面,说明在检测到APP分组发送时的连接维持程序21的动作。 Next, the operation when connection is detected in the APP packet transmission program 21 is maintained. 在这种情况下,在现在的方式是第2或第3方式时(图8的S30:Y),即进行空分组的发送控制时,空分组剩余时间45根据现在的方式进行初始化(S31)。 In this case, in the present embodiment is the second or the third embodiment (S30 in FIG. 8: Y), i.e., when the empty packet transmission control, null packets 45 initializes the remaining time (S31) according to the present embodiment . 即,在现在的方式是第2方式时,空分组剩余时间45以{广播接收值46-余量时间42}进行初始化,在现在的方式是第3方式时,空分组剩余时间45以1秒进行初始化。 That is, in the present mode is the second mode, null packets remaining time value 45 to the broadcast receiving {46- 42} margin time is initialized and the current mode is the third mode, the remaining time 45 null packets in 1 second initialized.

下面,说明在检测到定时器信号时的连接维持程序21的动作。 Next, the connecting operation program 21 is maintained when the timer signal is detected. 在现在的方式是第2或第3方式时(图9的S50:Y),空分组剩余时间进行减法计数(S51)。 In the current mode is the second or the third embodiment (S50 in FIG. 9: Y), null packets for the remaining time counting down (S51). 若利用减法计数,空分组剩余时间45变为0(S52:Y),则发送空分组(S53),与上述的S31相同,空分组剩余时间45根据现在的方式进行初始化(S54)。 When using the subtraction count, the time remaining NULL packets 45 becomes 0 (S52: Y), an empty packet is transmitted (S53), the same as the above-described S31, null packets 45 initializes the remaining time (S54) according to the present embodiment.

下面,说明在检测到广播分组B的接收时的连接维持程序21的动作。 Next, operation of the link upon detection of packet B receives a broadcast program 21 is maintained. 首先,从图6所示的广播分组B取出自己的切断时间(S60)。 First, take his time off (S60) from the broadcast packet B shown in FIG. 6. 在该取出中,若在广播分组B的请求接受部分有与自己(接收广播分组B的终端装置1)的ID相同的终端ID,则取出该请求时间,若没有相同的终端ID,则取出缺省部分的缺省切断时间。 Same ID as the terminal ID in the extraction, the request when the packet B in the broadcast receiving portion has with its own (the terminal apparatus receives a broadcast packet B 1), then remove the request time, if not the same terminal ID, remove missing the default part of the province cut off time. 在取出的切断时间与广播接收值46相等时(S61:Y),由于不需要更新广播接收值46,因此处理结束。 When removing off the broadcast receiving time and the value is equal to 46 (S61: Y), it is not necessary to update the broadcast reception value 46, the process ends. 在取出的切断时间与广播接收值46不相等的情况下(S61:N),在现在的方式不是第2方式时(S62:N),取出的切断时间作为广播接收值46保存在存储区(S65)。 In the withdrawn off time of the broadcast reception value 46 is not equal (S61: N), when the current mode is not the second mode (S62: N), taken off time as a broadcast received value 46 stored in the storage area ( S65). 在现在的方式是第2方式时(S62:Y),即接受根据变更请求分组的变更请求,广播第2方式请求时间43时,由于空分组的发送时刻改变,因此发送空分组(S63),空分组剩余时间以{第2方式请求时间43-余量时间42}进行初始化(S64),再将取出的切断时间作为广播接收值46保存在存储区(S65)。 In the current mode is the second embodiment: According to Change Request change request packet, broadcasting the second mode request time 43 (S62 Y), i.e. to accept, since the transmission time of a null packet is changed, thus transmitting a null packet (S63,), nULL packets remaining time of the second mode request time {43 42} margin time is initialized (S64), and then taken off time value is stored as the broadcast reception in the storage area 46 (S65).

图10是表示接入点2的动作、即控制程序34的动作的流程图。 FIG 10 is a diagram showing the operation of the access point 2, i.e., a flowchart of the operation of the control program 34. 控制程序34随时监视以下的事件,即接收连接请求分组、接收变更请求分组、接收APP分组、每隔一定时间产生定时器信号、以及每广播周期产生广播指示信号,若检测到事件发生,则进行与事件相应的处理。 The control program 34 always monitor the following events, i.e., receives the connection request packet, receiving a change request packet, receiving APP packet, generate a timer signal, and generating a broadcast every broadcast cycle indicative signal at predetermined time intervals, upon detection of the event, is performed processing corresponding to the event.

首先,说明在检测到接收连接请求分组时的控制程序34的动作。 First, in operation 34 detects the control routine receives the connection request packet. 在这种情况下,将发送源的终端装置1的数据登录在终端装置管理表48中,将切断时间进行初始化(S70)。 In this case, a data transmission source terminal device 1 registered in the terminal device management table 48, the cut time is initialized (S70). 具体来说,将发送源的终端装置1的ID记录在终端装置管理表48的终端ID48a中,请求有无接受48c设定为[无],再有切断剩余时间48b以缺省切断时间47进行初始化。 Specifically, the transmission source terminal device ID 1 recorded in the terminal management table of the terminal apparatus ID48a 48, the presence or absence of a request accepted 48c is set to [NO], then there is time remaining 48b to the default cut-off time 47 initialization. 实际上,虽然是用无线通信驱动程序35接收连接请求分组,并通过OS25,控制程序34接受连接请求分组,但这里作为控制程序34接收连接请求分组。 In fact, although the wireless communication driver receiving the connection request packet 35, and through OS25, the control program 34 accepts the connection request packet, but here 34 receives the connection request packet as a control program. 关于这一点,对于变更请求分组等也同样。 On this point, the request packet and so also for change.

然后,说明在检测到接收变更请求分组时的控制程序34的动作。 Then, the operation of the control program when receiving the change request packet 34 is detected. 首先,决定是否接受变更请求、以及是否取消已接受的变更请求(S75)。 First, decide whether to accept change requests, and whether to cancel the change request (S75) has been accepted. 在本实施形态中由于规定了接受变更请求的终端装置1的台数的上限值,因此若终端装置管理表48的请求有无接受48c的为[有]的个数不到上限值,则接受变更请求。 In the present embodiment, since the upper limit value of a predetermined number of terminal apparatus 1 accepts the change request, so the request management table 48 when the terminal device 48c receiving the presence or absence of the number of [have] is less than the upper limit, the change was accepted. 另外,也接受来自己接受变更请求的终端装置1、即请求有无接受48c为[有]的终端装置1的变更请求。 In addition, to accept a change request accepting own terminal apparatus 1, i.e., whether or request change request accepting 48c is 1 [has] a terminal apparatus.

另外,在终端装置管理表48的请求有无接受48c的为[有]的个数成为上限值,而且变更请求分组的发送源不是己接受变更请求的终端装置1时,根据规定的规则,决定是否拒绝变更请求,或者是否取消发送源以外的终端装置1的接受,接受新的变更请求。 Further, the requesting terminal device management table 48 as the presence or absence of acceptable 48c [have] becomes the upper limit value of the number, and change request transmission source is not a packet has accepted the change request when the terminal 1, according to a predetermined rule means, decide whether to reject the change request, or whether to cancel the receiving terminal apparatus other than the transmission source 1, to accept the new change request. 例如,若已接受的全部变更请求的类型号48d是优先级最高的[3](第3类型),则拒绝新的变更请求。 For example, all changes Ruoyi type number received request is the highest priority 48d [3] (3 types), a new change request is rejected. 与此不同的是,若己接受的变更请求中有类型号48d为[2](第2类型)的,而且新的变更请求有关的类型号为[3],则取消接受类型号48d为[2]的变更请求,同时接受新的变更请求。 In contrast, the change request when the already accepted There type number 48d is a [2] (second type), and the new change request type number [3], the cancel acceptance type number 48d is [ 2] change requests, and accept the new change request. 另外,如上所述,在变更请求分组中包含应用程序24的类型号,该类型号与终端装置管理表48的类型号48d进行比较。 Further, as described above, comprising the application type number of the change request packet 24, the class model with the terminal device management table 48 of the type 48d are compared.

然后,在接受变更请求时,更新终端装置管理表48(S76)。 Then, when the change was accepted, update the terminal device management table 48 (S76). 具体来说,终端装置管理表48的发送源终端装置1的请求有无接受48c设定为[有],在类型号48d中设定变更请求分组中的类型号,在请求时间48e中设定变更请求分组中的第2或第3方式请求时间43或44。 Specifically, the terminal requests the transmission source terminal device management table 48 of the receiving apparatus 1 whether or 48c is set to [there], setting change request packet type number in the type number 48d, 48e is set at a request time change request packet in the second time or the third mode request 43 or 44. 再有,在随着接受变更请求而取消其它的终端装置1的接受时,将该终端装置1的请求有无接受48c设定为[无]。 Further, when receiving change request is canceled as the other terminal apparatus 1 accepts the request of the terminal apparatus 1 to accept the presence or absence 48c is set to [NO]. 然后,将变更请求分组的发送源的终端装置1及取消接受的终端装置1的切断剩余时间48b进行初始化(S77)。 Then, the terminal apparatus changes the transmission source request packet and a remaining time of the cutting device cancels receiving terminal 48b is initialized to 1 (S77). 初始化是根据请求有无接受48c的值利用请求时间48e或缺省切断时间47来进行的。 The initialization request is accepted value using presence or absence of 48c or 48e default request time to the off time 47. 这里没有将广播分组B进行广播,但这里若进行广播,则终端装置1能够立即知道上述的接受、拒绝或取消,并能够根据新广播的值立即进行连接维持用的控制。 There is not a broadcast packet broadcasts B, but if there is broadcast, the terminal device 1 can know immediately above accept, reject or cancel, and can be immediately connected to a maintenance control according to the value of the new broadcast.

然后,说明在检测到每广播周期发出广播指示信号时的控制程序34的动作。 Next, the control program issues an operation instruction signal 34 at the time of the broadcast is detected in every broadcast cycle. 若检测到广播指示信号,则根据终端装置管理表48生成图6所示的广播分组B,并将生成的广播分组B进行广播(S80)。 If the detected signal is indicative of the broadcast, the packet B illustrated in the broadcast terminal 6 generates a device management table 48 in FIG, B and the generated broadcast packet broadcast (S80).

然后,说明在检测到每隔一定时间发出定时器信号时的控制程序34的动作。 Then, the operation control routine when the timer signal is sent in regular intervals detected 34. 首先,对终端装置管理表48的各终端装置1的切断剩余时间48b进行减法计数(S85)。 First, the terminal device management table 48 of each terminal 1 is cut off the remaining time counting means 48b performs subtraction (S85). 对于通过减法计数使切断剩余时间48b成为0的终端装置1,将回路切断,将该终端装置1的数据从终端装置管理表48中删除(S86)。 For the remaining time the cutting by the subtraction counter 48b becomes 0 terminal device 1, the circuit cut off, the data terminal device 1 from the terminal device management table 48 is deleted (S86). 即,对于无通信期间到达切断时间(切断剩余时间48b的初始值)的终端装置1,将回路切断。 That is, during the non-communication time of arrival cutting (cutting the initial value of the remaining time 48b) of the terminal apparatus 1, the circuit cut off. 然后,说明在检测到接收APP分组时的控制程序34的动作。 Then, the operation of the receiver 34 in the control program detects when the APP packet. 在这种情况下,由于无通信期间中断,因此将APP分组的发送源的切断剩余时间48b进行初始化。 In this case, since there is no communication interruption period, thus cutting the remaining time of the APP packet transmission source 48b is initialized.

以上,是假设终端装置1与接入点2之间的回路状态(通信状态)良好的情况进行说明的。 Above, a state is assumed that the circuit between the terminal apparatus and the access point 1 2 (communication state) will be described in the case where good. 但是,因通信量的增加而发生阻塞,或者因终端装置1的位置变化等而使无线通信的电波强度降低。 However, due to increased traffic obstruction occurs, or due to a change in position of the terminal apparatus of the other wireless communication radio field intensity is reduced. 若在回路状态不好时从终端装置1进行服务器3的文件更新等,则如上所述,有产生使文件损坏等问题的危险。 If the risk of a server 3 updates the file from the terminal apparatus 1 in a bad state and the like in the circuit, as described above, so that there are generated problems such as file corruption.

因此,若监视回路状态的回路状态监视程序22(参照图2)检测出回路状态不良或预测出恶化,则通知操作禁止程序23,使得禁止键盘12及鼠标的操作,接受了该通知的操作禁止程序23就禁止键盘12及鼠标13的操作。 Thus, if the monitor loop status circuit status monitor 22 (see FIG. 2) detect a defective or predicted deterioration loop status, the operator is notified prohibition program 23, so that the operation prohibition keyboard 12 and a mouse, accepts an operation of the notification prohibiting program 23 on the prohibition of operating the keyboard 12 and mouse 13. 这样做,就防止在回路状态不良时利用键盘12及鼠标13的操作来进行服务器3的文件更新处理等。 In doing so, it is prevented by the operation of the keyboard 12 and the mouse 13 when the failure state of the circuit 3 to the server file update processing. 但是,由于也有的情况下一律禁止操作并不方便,因此在按下后述的解除按钮时,作为例外来解除操作禁止。 However, because in some cases also prohibited operation is not easy, so when the release button is pressed described below, as an exception to the release operation is prohibited. 以下,说明回路状态监视程序22及操作禁止程序23。 Hereinafter, the status monitor circuit 22 and the operation program 23 is prohibited.

图11所示为回路状态监视程序22的动作的流程图。 FIG 11 is a flowchart of the operation of the loop status monitor 22 shown in FIG. 该回路状态监视程序22每隔规定的时间间隔(例如10秒间隔)利用OS25进行起动,检测及预测回路状态(S100)。 The predetermined loop status monitor 22 every time interval (e.g. 10 seconds intervals) using OS25 be started, detection and prediction circuit state (S100). 根据通过OS25从无线通信驱动程序26接受的各种信息,例如接收分组的损失状况、误码率、传送延迟、电波强度、阻塞标记等信息,进行回路状态的检测及预测。 According to various information received from the wireless communication driver 26 through OS25, for example, receives a packet loss condition, the error rate, transmission delay of radio wave strength, the blocking flag information, detection and prediction circuit state. 作为预测方法,可以利用以往众所周知的方法、例如专利文献3所示的方法等。 As the prediction method, conventionally known methods may be utilized, a method disclosed in Patent Document 3, for example. 然后,在检测出现在的回路状态不好时,或者预测回路状态恶化时(S101:Y),对操作禁止程序23进行操作禁止通知(S102)。 Then, when the detection circuit occurs in a bad state, state deteriorates or loop prediction (S101: Y), the operation prohibition program operation prohibition notification (S102) 23. 该通知中也包含禁止操作的理由([电波强度降低]等)。 The notification also contains the reason for prohibiting the operation ([radio wave strength decreases], etc.). 再有,将表示是操作禁止状态的操作禁止标记设定为1(S103)。 Further, operation of the operation prohibition indicating a prohibition state flag is set to 1 (S103). 操作禁止标记在电源接通时进行初始化。 Operation inhibition flag is initialized at power on. 利用上述的操作禁止通知,如后所述,禁止键盘及鼠标13的操作。 Prohibition notification, as described later, the operation prohibition of the use of keyboard and mouse 13 of the above-described operation.

另一方面,在现在的回路状态良好而且也未预测出回路状态恶化(S101:N)、同时操作禁止标记是1时(S104:Y),对操作禁止程序23进行禁止解除通知(S105),同时对操作禁止标记设定为(OS106)。 On the other hand, in a good state and the current loop circuit are also not predicted state deteriorates (S101: N), while the operation inhibition flag is 1 (S104: Y), the operation prohibition canceling prohibition program notification (S105) 23, while the operation inhibition flag is set (OS106). 即,在操作禁止通知后,若回路状态变成良好,则进行禁止解除通知,如后所述,能够进行键盘及鼠标13的操作。 That is, after the operation prohibition notification, if the circuit state becomes good, prohibition release notification is performed, as described later, capable of operating the keyboard and mouse 13. 另外,上述的操作禁止通知及禁止解除通知实际上是通过OS25传送给操作禁止程序23的。 Further, the operation prohibition and prohibition release notification notified by actually transmitting OS25 to the program 23 of the operation prohibition.

图12所示为操作禁止程序23的动作的流程图。 As shown in FIG. 12 is a flowchart showing the operation of the operation prohibition program 23. 该操作禁止程序23在正常状态下处于上述的操作禁止通知的等待状态(S110)。 The operation program 23 in the above-described prohibition operation prohibition notification waiting state (S110) in the normal state. 若利用回路状态监视程序22进行操作禁止通知,则解除等待状态。 When the loop status monitor 22 using the operation prohibition notification, the wait state is released. 在等待状态解除后,如图13(a)所示,在显示单元15(参照图2)的画面的一部分显示最大优先级的对话框110(S111),该对话框110显示操作禁止消息110a及解除按钮110b。 After the waiting state is released, FIG. 13 (a), a portion of the screen of the display unit 15 (see FIG. 2) of the highest priority display a dialog box 110 (S111), the operation prohibition message dialog 110 displays 110a and release button 110b. 在操作禁止消息110a中,[电波强度降低]是操作禁止的理由(或原因),根据从回路状态监视程序22通知的理由进行显示。 In operation 110a in the prohibit message, [decrease the radio intensity] is the reason for prohibiting the operation (or reasons), the reasons for display from the loop status monitor 22 notify. 由于这样显示操作禁止的理由,因此用户也能够采取适当的措施(例如,向接入点2的附近移动)。 Since such a display operation prohibition reasons, so the user can take appropriate action (e.g., to move to the vicinity of the access point 2).

另外,由于对OS25指示使得对话框110成为最大优先级,而且用操作禁止程序23接受键盘12及鼠标13的操作信号,因此禁止键盘12及鼠标13对应用程序24的操作。 Further, since the box 110 instructs the OS25 becomes maximum priority, and by prohibiting the operation keyboard 12 accepts an operation signal 23 and a mouse 13, keyboard 12, and thus prohibit the application program operating the mouse 13 24. 该禁止状态如后所述,若用鼠标13点击解除按钮,或者按下键盘12的空格键,则暂时(仅规定时间内)解除。 The prohibited state as described later, when the release button 13 with a mouse click, or press the keyboard spacebar 12, the temporary release (specified time only). 这里,是通过使用最大优先级的对话框110来禁止键盘12及鼠标13的操作,但也可以采用其它的方法。 Here, by using a highest priority box 110 to inhibit operation of the keyboard 12 and the mouse 13, but other methods may be employed. 另外,由于也有时会不注意按下空格键,因此也可以仅在用鼠标13点击解除按钮110b时解除禁止状态。 In addition, because sometimes will not pay attention to press the space bar, so the ban can be lifted only when the state of the release button 110b clicking with the mouse 13.
