Abstract

PROBLEM TO BE SOLVED: To provide a radio communication system which secures a line for a terminal which should be used originally so that the terminal is not unable to be connected because of a line shortage resulting from the connections of other terminals. SOLUTION: When the terminal which should be connected originally makes a connection request, a time-specified terminal connection control means 10112 decides that the terminal can be connected on the basis of connection possible/ impossible state information every time, obtained by referring to a time-specified connection possible/impossible state information storage means 1013, and current time, and makes connection, but when another terminal makes a connection request, the time-specified terminal connection control means 1012 decides that the connection can not be made, and no connection is made, so the terminal which should be connected originally in a specific time zone can have a communication without the line occupied by other terminals.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a radio terminal connection apparatus and a radio communication system in a line connection type private radio communication system.

[0002]

2. Description of the Related Art In recent years, with the development of wireless communication technology, digitization and speeding up of communication and miniaturization of terminals have been advanced, and application to various uses is considered. One of the digital wireless communication technologies, PHS (simple mobile phone system), may be applied to a wireless LAN system using data communication in addition to the original voice communication. Here, a classroom wireless LAN system to which PHS is applied will be described.

FIG. 21 is a configuration diagram of a classroom wireless LAN system using a PHS. In FIG. 21, reference numeral 2101 denotes a wireless terminal connection device, 2102 denotes a terminal device, 2103 denotes a wireless base station, and 2104 denotes a communication network. 21011 is a network side communication control means, 21012 is a network side connection control means, 210
Reference numeral 13 denotes a connection availability information storage unit, and reference numeral 21014 denotes a terminal movement management unit. 21021 is a terminal side communication control means,
21022 is a terminal side connection control means, 21023 is a terminal identification information storage means, and 21024 is a wireless transmission / reception means.

The operation of the classroom wireless LAN system configured as described above will be described. In order for the terminal device 2102 to communicate with a host on the communication network 2104, the terminal-side connection control means 21022
By extracting the terminal identification information from H.023 and sending it via the wireless transmission / reception means 21024 and the wireless base station 2103, an attempt is made to connect to the wireless terminal connection device 2101.

[0005] In the wireless terminal connection apparatus 2101, the network side connection control means 21012 compares the terminal identification information sent and the connection availability information retrieved from the connection availability information storage means 21013 to determine whether or not the connection is possible. Here, the connection availability information is, for example, simply a list of terminal identification information that can be connected, and is registered in advance by a subscriber registration procedure or the like.

[0006] If the connection becomes possible by the determination, an authentication procedure is performed as necessary, a line is secured for the terminal device 2102, and the connection state is established. The communication between the terminal device 2102 and the communication network 2104 is performed by communicating with the communication terminal 21021 via the wireless base station 2103.

On the other hand, when it is determined that connection is impossible, the terminal device 2102 is in a non-connection state and cannot communicate with the communication network 2104. Note that the communication network 2104 also includes the wireless network itself managed by the wireless terminal connection device 2101 as a concept.

One wireless base station 2103 can simultaneously connect up to four wireless terminals 2102. The wireless terminal connection device 2101 has a configuration having a plurality of wireless base stations 2103, so that the number of terminal devices 2102 that can be connected simultaneously can be increased. At this time, which wireless base station 2103 the terminal device 2102 is communicating with is managed by the terminal mobility management means 2014, and based on this management information, the network-side communication control means 21011 communicates via the appropriate wireless base station 2103. Control the communication.

Therefore, by arranging the wireless base station 2103 in each classroom, a classroom wireless LAN system in which each terminal can be used in each classroom can be realized.

[0010]

However, in the classroom system described above, there is a problem in that a terminal that is not taking a course is connected to the classroom connection device, thereby causing a shortage of lines and making it impossible to connect a terminal that is taking a course.

For example, consider a case where the present invention is applied to a classroom having a capacity of 40 people. Assuming that all students will connect terminal devices at the same time in one lecture held in this classroom, the number of terminals that can be connected simultaneously per base station is 4, so the number of wireless base stations to be installed Will be 10 units.

On the other hand, since the terminals owned by the students of all the lectures held in this classroom are registered in the wireless terminal connection device, the number of registered terminal devices is considered to be considerably larger than 40. . At this time, even if the student who took the lecture in this classroom ends the lecture and the time for the next lecture continues, the terminal device that is not to be attended, such as using the terminal device in the corridor in front of the classroom, will be connected to the wireless terminal connection device. Can easily occur due to the nature of wireless communication.

[0013] In such a situation, there is a problem that the terminal device not to be attended occupies the line limited to 40 terminals, and the terminal device to be attended cannot use the line because it cannot secure the line. Occur. This can be solved by placing a sufficient number of extra radio base stations, but this is not practical in terms of cost. This is the first example.

Further, it is assumed that the present invention is applied to two classrooms A and B which are spatially separated apart from the above example. The number of wireless base stations is set according to the number of lines required for each classroom. On the other hand, the terminal devices registered in the wireless terminal connection device are possessed by all the participants of the lectures given in the classroom. At this time, a situation in which a student who has only the qualification to attend the classroom A uses the terminal device near the classroom B during the lecture and is connected to the wireless terminal connection device can easily occur due to the nature of the wireless communication. Even in such a situation, there occurs a problem that the terminal device to be attended cannot use the line because the line cannot be secured. This is the second example.

Although the above two examples are applied to a classroom wireless LAN system, it can be seen that only this requires some kind of connection restriction. Furthermore, considering the coexistence with wireless voice communication terminals (cordless telephones) and the application to information provision services, there is a problem of securing a line for terminals that have the same usage rights even in a more complicated environment. Efficient connection restrictions are required. At the same time, the complexity of the environment causes a problem that it becomes difficult to manage connection restriction information for each terminal.

Further, even if the connection restriction is implemented, there remains a problem that the terminal whose connection is restricted may be damaged by sudden disconnection during communication.

The regulation control mechanism is defined in Appendix C of RCR STD-28 "Second Generation Cordless Telephone System Standard". In this method, terminals are mechanically grouped into restriction groups based on the value of terminal identification information, and control is performed to restrict traffic accessing the network by prohibiting connection operations for terminals in each group. Further, by adjusting the number of groups to be regulated at the same time, a gradual regulation level can be realized. During the enforcement of the regulations, the enforcement groups are changed regularly so that the regulations are not biased to specific groups. Further, since terminals having the attribute of a priority station are not subject to this restriction, a base station to which only the priority station can be connected can be realized by performing 100% restriction control.

However, since the regulation control is originally a concept for adjusting the traffic of the entire network, it is possible to limit the connection of only two types of terminals, that is, a terminal having a connection priority for each base station and a terminal other than the terminal. Therefore, it can be applied as a solution to the above-described problem of securing a line for each location in the second example, but cannot be applied to any other.

For example, the problem of securing a line for each time zone in the first example cannot be applied because it is not possible to switch a terminal having priority. Even if the mechanical division of the regulation group was changed so that it would be divided according to the lecture, and even if the regular implementation of the regulation group was expanded to match the lecture time, another time could be used in the same classroom. This is not applicable if there are students who take both classes given in the obi.

The present invention has been made to solve the above-described problems, and has as its first object to realize a wireless communication system in which a terminal to be originally used can secure a line and be connectable in a specific time zone.

[0021] It is a second object of the above-mentioned system that the terminal can be connected to terminals other than the terminal to be used as much as possible, and that the line is effectively used.

It is a third object of the above system to flexibly restrict connection of a terminal in a complicated environment and to facilitate management of connection restriction information.

In order to communicate with the host on the terminal 4, the terminal-side connection control means 1022 first extracts the terminal identification information from the terminal identification information storage means 1023, incorporates it into the connection request signal, and passes through the wireless transmission / reception means 1024 and the wireless base station 103. Then, an attempt is made to connect to the wireless terminal connection apparatus 101 by sending the message. In the wireless terminal connection device 101, the time designation terminal connection control means 10

Next, connection enable / disable information corresponding to the via base station is extracted from the time base station combined connection enable / disable information (1004), and a connectable terminal list corresponding to the current time is extracted (1005). Next, it is determined whether the terminal identification information is in the connectable terminal list (1006). If it is determined that the connection is in the list, the connection expiration is registered in the timer for disconnection during the next connection restriction (1007), a line is reserved for this terminal, and the terminal is notified of the connection success. (1008). On the other hand, if it is determined in step 1006 that the connection is not in the list, the terminal is notified of the connection failure without securing the line (1009).

Next, the internal connection availability information is extracted from the internal connection availability information storage means (1803). Next, the user corresponding to the terminal identification information is specified from the internal connection availability information (1804). If the classroom is identified, the classroom corresponding to the base station is identified from the internal connection availability information (1805).
Further, a student list corresponding to the current time of the classroom is extracted from the external database (1806).

Next, it is determined whether the user corresponding to the terminal is on the student list (1807). If it is determined that the connection is in the list, the connection time limit is registered in the timer for disconnection at the time of the next connection restriction (1808), a line is reserved for this terminal, and a notification of connection success is sent to the terminal. (1809).

On the other hand, if it is determined in step 1807 that the user is not in the list or if the user cannot be specified in step 1804, the terminal is notified of the connection failure without securing the line (1810).

Here, the internal connection availability information of the present embodiment will be described with an example.

(Embodiment 7) FIG. 19 is a configuration diagram of a wireless communication system in an embodiment corresponding to claim 7 of the present invention. In FIG. 19, reference numeral 701 denotes a wireless terminal connection device, 702 denotes a terminal device, 7031, 7032, and 703.
3 is a wireless base station and 104 is a communication network. Also 7011
Denotes communication control means on the disconnection notice network side, 7012 denotes terminal connection control means, 7013 denotes connection availability information storage means, and 7014 denotes terminal movement management means. Reference numeral 7021 denotes a terminal-side communication control unit corresponding to a disconnection notice, 7022 denotes a terminal-side connection control unit,
Reference numeral 7023 denotes a terminal identification information storage unit, 7024 denotes a wireless transmission / reception unit, and 7025 denotes a disconnection notice disconnection unit.

The operation of the radio communication system configured as described above, which is different from the third embodiment, will be described.
The disconnection notice network side communication control means 7011 transmits a disconnection notice signal to the terminal when the network side and the terminal connection control means 7012 of the third embodiment disconnect the line by judging that the line is replaceable. In the terminal device 702, upon receiving the disconnection notice signal, the terminal-side communication control means 7021 indicates to the user that the connection has been restricted upon receiving the disconnection notice signal, and then operates the disconnection notice time disconnection means after a predetermined time to perform the disconnection processing. I do.

Here, the disconnection notice network side communication control means 702
The disconnection procedure in 1 will be described in more detail with reference to FIG. FIG. 20A is a flowchart showing an operation when a disconnection process is instructed by the terminal connection control means in step 1209 of FIG. 8 described in the third embodiment. First, a timer until disconnection from the network side is set (200
1). Next, a time before the disconnection is set in the disconnection notice signal and transmitted to the terminal (2002). Then, wait until the timer expires or the terminal is disconnected (2
003, 2004). If the timer has expired, the process proceeds to step 2005 to disconnect the line from the network side and report the end of the disconnection processing to the terminal connection control means. When the terminal is disconnected, the termination of the disconnection processing is reported to the terminal connection control means as it is. Further, the terminal-side disconnection procedure of the disconnection notice corresponding terminal-side communication control means 7021 will be described in further detail with reference to FIG. FIG.
(B) is a flowchart showing an operation of the disconnection notice corresponding terminal-side communication control means 7021 when a disconnection notice signal is received. When the disconnection notice signal is received, first, the time until disconnection is extracted from the signal (2006). Next, a timer until disconnection processing is set based on the time (200
7). Next, the user is notified that the connection is restricted and the time until the disconnection is made (2008). Then, it waits until the timer expires or until the user instructs disconnection (2009, 2010). At this time, normal communication continues. If the time has expired due to the timer, the process proceeds to step 2011 to perform communication interruption processing such as saving communication interruption information for resuming communication, and then perform step 2012.
Then, the disconnection means is operated at disconnection notice to disconnect the line. When a disconnection instruction is given from the user, the process proceeds to step 2012 and disconnection is performed by operating disconnection means at the time of disconnection notice. Therefore, the user of the terminal device can perform evacuation work such as ending the application in use after saving the data by the time limit.

[0115] Here, the case where the time until disconnection is set in the disconnection notice signal has been described, but the time may not be transmitted using a fixed value. Conversely, it is conceivable to set more detailed information such as at what base station and at what time in the disconnection notice signal. As the means for notifying the user of the connection restriction, a screen display, a sound, or the like may be used. Further, as the communication interruption processing, interruption processing of an application that is using communication may be considered. Further, here, the description has been given of the case applied to claim 3, but the present invention can be easily applied to claims 4, 5, and 6 in the same manner.

As described above, according to the present embodiment, a mechanism for notifying the user of the connection and a mechanism for delaying the disconnection for a certain period of time at the time of disconnection due to line adjustment, and a mechanism for notifying the user to the terminal and a communication interruption. By adding the mechanism for performing the processing, it is possible to minimize the damage to the user when the line of the communicating terminal is disconnected due to the connection restriction.

[0117]

As described above, according to the present invention, there is obtained an advantageous effect that a terminal to be originally used can secure a line and connect in a specific time zone.

Further, it is possible to connect as much as possible to terminals other than the terminal that should be used, and an advantageous effect that the line can be effectively used is obtained.

Further, there is an advantageous effect that the connection of the terminal can be flexibly restricted even in a complicated environment, and the management of the connection restriction information is easy.

Further, there is an advantageous effect that damage caused by sudden disconnection during communication at a terminal having a restricted connection is minimized.
