Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a PHS-Wireless Room Area Network for delivering information such as a message or an electronic file while relaying between wireless terminals, and in particular, a PHS terminal which is located at a radio wave reach distance outdoors. The present invention relates to an electronic file delivery method that can cope with a case in which communication is not performed between PHS terminals or when direct communication is not possible.

[0002]

2. Description of the Related Art In recent years, the 1997 IEICE Communications Society Conference B-5-90 "A study of file delivery methods in PHS-WRAN", the 1998 IEICE General Conference
B-5-146 "Development of PHS-WRAN Application" or "1998 IEICE General Conference B-5-147" PHS-
WRAN file delivery characteristics "

[0003] PHS-, which delivers information such as messages or electronic files while relay relaying between wireless terminals
Wireless Room Area Network (hereinafter PHS-WRAN)
Is introduced. This PHS-WRAN is
This is a system for performing direct communication between PHS terminals using the direct communication function between handset units of the PHS, and a data communication network can be constructed ad hoc in a space as large as a conference room or a classroom.

[0004] Since the PHS is originally a connection type communication system, unlike a packet switching type communication system, it is impossible to broadcast information in a broadcast manner. Therefore, there is a problem that the delivery time increases in proportion to the number of terminals to be delivered. Therefore, this PHS-WRAN
In this example, a broadcast method not provided in the PHS is realized in a pseudo manner by a delivery method in which information is delivered in a relay manner between a plurality of PHS terminals. With this unique delivery method, peer-to-pe
The delivery time has been greatly improved compared to the case where information is delivered by er.

[0005]

The PHS as described above
-WRAN is a system on the premise that direct communication can be performed between all PHS terminals used. Thus, PH
In S-WRAN, a delivery route is determined on the assumption that each terminal can directly communicate.

[0006] The communication distance of the PHS used in the PHS-WRAN by direct telephone communication between slave units is 100 m within line of sight.
It is said that it is not necessarily used only in a closed space such as a conference room or a classroom, and can be used in an outdoor open space.

However, when used outdoors, PH
Due to problems such as the location of the S terminal and the surrounding propagation environment,
It is unlikely that all PHS terminals are located within the radio wave reach. In order to build a simple regional network in which terminals communicate directly with each other in such an environment, it is necessary to build a network that relays information between the terminals. A delivery route needs to be determined.

The present invention relates to an electronic file delivery method required for constructing a simple data communication network in which wireless terminals directly communicate with each other, and relates to a method for constructing an ad hoc data communication network not only indoors but also outdoors. The purpose is to provide.

[0009]

That is, the invention of claim 1 is an electronic file delivery method in which a plurality of wireless terminals exist in a communication sector and an electronic file is delivered in the communication sector.
One representative wireless terminal (representative terminal) selected from the plurality of wireless terminals registers a call number of each wireless terminal in advance, stores a list of the call numbers as a call number list,

[0010] The representative terminal performs a one-to-one communication with other wireless terminals in turn, excluding itself, and registers a call number of a wireless terminal with which the representative terminal can communicate, and a first step. 1
After the step of, after the second step of requesting the registered wireless terminal to search for a nearby wireless terminal that can communicate, and after receiving search results from all wireless terminals that have registered the call number, A third step of storing call numbers of all wireless terminals notified from the registered wireless terminal;

After the third step, the call number of the registered wireless terminal is compared with the call number in the call number list, and the wireless terminals other than those registered by themselves are regarded as unregistered terminals.
A fourth step of newly registering the call number of the unregistered terminal; and, after the end of the fourth step, if the unregistered terminal does not exist, the process is terminated, and the process proceeds to an eighth step. A fifth step of requesting an unregistered terminal to search for a communicable wireless terminal if the registered terminal exists;

After completing the fifth step, after receiving respective search results from all the unregistered terminals, a sixth step of storing the call numbers of all wireless terminals notified from the unregistered terminals. A seventh step of determining whether or not the unregistered terminal exists after the end of the sixth step;

After the end of the seventh step, if the unregistered terminal does not exist, the process is terminated and the process proceeds to an eighth step.
Returning to the step, the processes from the fourth to the seventh steps are repeated until the unregistered terminal disappears, and when the unregistered terminal disappears, the process shifts to the eighth step,

In an eighth step, a delivery route between the wireless terminals is formed from the results obtained by the processes of the fourth to seventh steps, and after the delivery route is formed, the process is terminated. An electronic file delivery method for delivering the electronic file in a relay manner based on the delivery route information determined in the eighth step.

According to a second aspect of the present invention, in the electronic file delivery method according to the first aspect, all wireless terminals including the representative terminal simultaneously deliver a call number list at the time of communication. It is.

According to a third aspect of the present invention, the representative terminal is the first aspect.
Alternatively, in the electronic file delivery method according to claim 2, the delivery route information determined in the sixth step is configured to be notified to all other wireless terminals.

According to a fourth aspect of the present invention, in the electronic file delivery method according to the first or second aspect, when the delivery of the electronic file to a certain wireless terminal has ceased, the delivery to the wireless terminal is performed. The transmitting-side wireless terminal notifies the representative terminal that the delivery has ended,

When the representative terminal having received the notification determines that there is a wireless terminal to be originally delivered by the wireless terminal, the representative terminal determines a new delivery route from the delivery route information, and determines the delivery route on the transmitting side. The transmission is notified to the wireless terminal, and the transmitting-side wireless terminal is configured to start delivery again based on the new delivery route.

According to a fifth aspect of the present invention, in the electronic file delivery method according to the third aspect, when the delivery of the electronic file to a certain wireless terminal has ceased, the wireless communication of the transmitting side that has delivered to the wireless terminal has been completed. If the terminal determines that there is a wireless terminal that the wireless terminal should originally deliver,
Based on the delivery route information notified from the representative terminal,
In this system, a new delivery route is determined by itself, and delivery is started again based on the new delivery route.

According to a sixth aspect of the present invention, there is provided a storage medium storing a procedure of the electronic file delivery method according to any one of the first to fifth aspects as a program.

In the present invention, a specific wireless terminal in the communication sector (for example, a wireless terminal that is a representative in the communication sector, or a wireless terminal that is a source of information for delivering a message or an electronic file) is defined as a representative terminal. The representative terminal is configured to call each wireless terminal existing in the communication sector (for example, a telephone number, or a telephone number and a serial number. However, the serial number is used to organize each wireless terminal regardless of the telephone number. (Corresponding to the given serial number) is stored in advance, and the representative terminal is the center, and the relay route between all the wireless terminals is automatically determined.

For example, when a wireless terminal is a PHS terminal and a network is constructed outdoors using a direct call function between handset units of the PHS, each wireless terminal to be used should be considered in consideration of the reachable distance of radio waves. It is necessary to install a wireless terminal while considering that the terminal can directly communicate. When arranging a wireless terminal while being conscious of a radio wave reach distance or the like, there is a burden on human work involved in installing the wireless terminal.

In order to reduce the burden of this human work,
It is necessary to automatically search for wireless terminals capable of direct communication between wireless terminals. In the present invention, a certain representative terminal plays a central role, requests each wireless terminal to search for a communicable peripheral terminal, and tallies the search results. It is possible to determine a relay route between wireless terminals, that is, a delivery route.

[0024]

FIG. 1 is a flow chart showing a first example of an embodiment of an electronic file delivery method according to the present invention. This figure shows the flow until the representative terminal configures the electronic file delivery route, and the symbols S1 to S10 in the figure correspond to the descriptions in the following description. Also, the first step of FIG.
The operation in each step of the eighth step corresponds to the means described in the first aspect of the present invention.

In the first step (S1), one-to-one communication is sequentially performed with respect to the other wireless terminals except the own terminal, and the calling number of the wireless terminal with which the own terminal can communicate is registered.

In the second step (S2), after completion of the first step, the registered wireless terminal is requested to search for a nearby wireless terminal with which communication is possible.

In the third step (S3), after receiving the search results from all the registered wireless terminals, the call numbers of all the wireless terminals notified from the registered wireless terminals are stored.

In the fourth step (S4), after the completion of the third step, the call number of the registered wireless terminal is compared with the call number in the call number list, and the wireless terminals other than the registered wireless terminal are unregistered. A registered terminal is called, and the call number of the unregistered terminal is newly registered.

In the fifth step (S5), after the end of the fourth step, if the unregistered terminal does not exist, the process is terminated and the process proceeds to the eighth step, and if the unregistered terminal exists, Requests the unregistered terminal to search for a communicable wireless terminal (S9).

In the sixth (S6) step, after the end of the fifth step, after receiving the respective search results from all the unregistered terminals, the call numbers of all the wireless terminals notified from the unregistered terminals are received. Is stored.

In the seventh step (S7), after the end of the sixth step, it is determined whether or not the unregistered terminal exists.

Then, after the end of the seventh step, if the unregistered terminal does not exist, the process is terminated and the process proceeds to an eighth step. If the unregistered terminal exists,
Returning to the fourth step, the processes from the fourth to the seventh steps are repeated until the unregistered terminal disappears, and the process shifts to the eighth step when the unregistered terminal disappears (S10).

Finally, in an eighth step (S8), a delivery route between the wireless terminals is constructed from the results obtained by the processes from the fourth to seventh steps, and the delivery route is constructed. After that, the process ends. With the above processing, the representative terminal forms an electronic file delivery route.

The calling number list stored in advance by the representative terminal may be delivered in the form of an attachment when each user performs communication, as described in claim 2. The same call number list as the representative terminal may be stored. Under the condition that the call number list is stored in all the wireless terminals including the representative terminal, it is not necessary to attach the call number list at the time of delivery.

FIG. 2 summarizes a series of flows for configuring the electronic file delivery route shown in FIG. In the figure, the terminal numbers are indicated by circles to make the display easier to see. These terminal numbers correspond to the terminal numbers in the drawings described below.

Here, as shown in FIGS. 3 to 5, it is assumed that there are ten wireless terminals 1 to 10 in the communication sector 11, and the wireless terminals are PHS terminals. In the figure, a terminal that has received a search instruction request attempts communication with all terminals except for the X mark and the ☆ mark (the ☆ mark is a search request instruction transmission source terminal). Hereinafter, the procedure of the delivery route configuration of FIG.
This will be described with reference to FIG.

In FIG. 3, terminal 1 is a representative terminal.
The representative terminal repeats the calling process in a peer-to-peer manner for each terminal based on the call numbers of the terminals 2 to 10 stored in advance (here, the terminal numbers in ascending order), and communicates with the terminals. (In FIG. 2, communication is possible with the three terminals 2, 4, and 5, and the call numbers of the three terminals are registered).

Subsequently, the terminal 1 requests each of the registered terminals to search for a peripheral terminal with which communication is possible in sequence. After receiving the search request instruction from terminal 1, terminal 2 repeats peer-to-peer communication with terminal 1 and all terminals except itself (here, terminal 3 → 4 → 5 → 6 → 7 → 8 → 9 → 10 in order), and determine a terminal with which it can communicate (in FIG. 2, it can communicate with two terminals, terminals 3 and 4).

Then, the search result is sent to the terminal 1. Here, the terminal 1 stores the terminals 3 and 4 as terminals with which the terminal 2 can communicate. The terminal 1 having received the search result from the terminal 2 requests the subsequent terminal 4 to perform the same processing. Terminal 4
Attempt is made to communicate between the terminal 1 indicated by a cross in the figure and eight terminals except itself.

As a result, the communication with the terminals 2, 3, 5, 6, and 7 is successful, the search result is reported to the terminal 1 as described later, and the process ends. That is, the terminal 4 repeats communication in a peer-to-peer manner with the peripheral terminal similarly to the terminal 2 (here, the terminal 2 is connected in the order of 3 → 5 → 6 → 7 → 8 → 9 → 10). Then, the terminal that can communicate with itself is determined (in FIG. 2, it can communicate with terminals 2, 3, 5, 6, and 7).

Then, the search result is sent to the terminal 1. Here, the terminal 1 stores the terminals 2, 3, 5, 6, and 7 as terminals with which the terminal 4 can communicate. FIG. 4 shows a search image of the terminal 4. Subsequently, the same processing is repeated for the terminal 5. The representative terminal requests all terminals with which it can communicate to search for peripheral terminals, and receives search results from all terminals that have requested the search.

Next, the terminal 1 registers the registered terminal numbers (here, terminals 2, 4, 5) and the terminal numbers stored therein (here, terminals 2, 3, 4, 5, 6, 7, 9, 9). ), The terminals that have not been registered (here, terminals 3, 6, 7, and 9) are defined as unregistered terminals, and the unregistered terminals are newly registered.

There are two terminals that can communicate with the unregistered terminal 3, the terminal 2 and the terminal 4. Here, a similar search is requested to the terminal 3 by relaying the terminal 2 having the smaller terminal number. The search request to the unregistered terminals 6 and 7 is made via the terminal 4, and the search request to the unregistered terminal 9 is made via the terminal 5.

The terminal 3 which has received the search request from the terminal 2 registers which terminal the search request to itself has been relayed from the terminal 1 which is the representative terminal, and registers the terminal on this route (here Then, communication is repeated in a peer-to-peer manner with the terminals 1 and 2) and all the terminals except the terminal itself (here, the terminals are connected in the order of the terminals 4 to 10), and the terminal with which the terminal can communicate is determined. (In FIG. 2, communication with terminals 4, 6, and 8 is possible).

The search result is sent to the terminal 1 in such a manner that the search request is traced backward. Here, the terminal 1 stores the terminals 4, 6, and 8 as terminals with which the terminal 3 can communicate.
Similar processing is repeated for terminals 6, 7, and 9. FIG. 2 shows the search results.

Next, the terminal 1 registers the registered terminal numbers (here, terminals 2, 3, 4, 5, 6, 7, 9) and the terminal numbers stored therein (here, terminals 3, 4, 6, and 6). , 7,8,
9 and 10), a terminal that is not registered by itself (here, terminals 8 and 10) is defined as an unregistered terminal, and the unregistered terminal is newly registered.

The search request to terminal 8 is terminal 1 → 2 → 3 → 8
The terminal 8 that has been sent along the route and has received the search request communicates with terminals (here, terminals 1, 2, and 3) on the route and all terminals except itself by peer-to-peer. (Here, terminals 4 → 5 → 6 → 7 → 9 → 10 are connected in this order) to determine a terminal that can communicate with itself (communicable with terminal 6 in FIG. 2).

The search result is sent to the terminal 1 in such a manner that the search request is traced backward. FIG. 5 shows a search image of the terminal 8. Here, the terminal 1 stores the terminal 6 as a terminal with which the terminal 8 can communicate. Similar processing is repeated for the terminal 10. The search results are shown in FIG.

Next, the terminal 1 registers the registered terminal numbers (here, terminals 2, 3, 4, 5, 6, 7, 8, 9, 10).
It compares the number with the terminal number (in this case, terminal 6) stored by itself. As a result, when it is determined that there is no unregistered terminal, a series of processes constituting the delivery route is terminated, and a relay route between all the terminals is determined.

Then, the determined route information is delivered to each terminal using the delivery route. As a result, similarly to the terminal 1, each terminal can construct a delivery route in a case where the terminal itself becomes an information transmission source. According to the flow described above, the representative terminal automatically determines a relay route of each wireless terminal. FIGS. 6A and 6B
Is a delivery route obtained by the delivery route determination procedure.

In FIG. 6A, a route connected by a bold line is set as a basic delivery route, and this delivery route is configured based on information on a hatched portion on the left end of FIG. Thin lines are other deliverable routes. Normally, the representative terminal (here, terminal 1) distributes information along a route indicated by a thick line. Here, in the case where the delivery has been lost halfway, the delivery route is reconfigured as shown in (b).

In FIG. 6, the terminal 1 that cannot communicate with the terminal 4 requests the terminal 5 to deliver the terminals 6, 7, and 10 under the terminal 4, and notifies a new delivery route.

Here, in addition to the method of constructing and notifying a new delivery route at the terminal 1, the terminal 5 receiving the request from the terminal 1 creates a new delivery route based on the delivery route information managed by itself. There is also a method of constructing a delivery route. This can be realized by the terminal 1 previously delivering delivery route information between all terminals to each wireless terminal.

Next, FIGS. 7A to 7I show basic delivery routes when a wireless terminal other than the terminal 1 becomes a representative terminal. As a method of constructing the basic delivery route, the terminal 1 constructs a basic delivery route corresponding to each wireless terminal based on the delivery route information shown in FIG. 6, and a method based on the delivery route information delivered from the terminal 1. There is a method in which each wireless terminal configures its own basic delivery route.

When each wireless terminal receives a notification of a basic delivery route corresponding to each wireless terminal in addition to the delivery route information configured by the terminal 1, each wireless terminal does not configure its own route. If the notification is not received, the route is configured by each person. The terminal 1 arranges the wireless terminals in the order of the serial numbers, and manages a set of the telephone number and the serial number of each wireless terminal (here, the order of the terminals 1 to 10).

The management of the telephone number and the serial number is performed only by the representative terminal, or the common information is managed by all wireless terminals. Hereinafter, the procedure of configuring the basic delivery route when the terminal 2 becomes the representative terminal will be described.

(1) Since the terminal 2 can communicate with the terminals 1, 3, and 4, the branch is branched into three from the terminal 2 to the terminals 1, 3, and 4. Next, the tree is constructed in ascending order of the serial number. (2) Although the terminal 1 can communicate with the three terminals 2, 4, and 5, the route of the terminals 2 and 4 has already been determined. Then, from terminal 1 to terminal 5, 1
Branched.

(3) The terminal 3 can communicate with the four terminals 2, 4, 6, and 8, but focuses on the remaining terminals 6 and 8 because the routes of the terminals 2 and 4 have already been determined. Then, the terminal 3 branches into the terminals 6 and 8 in two. (4) The terminal 4 can communicate with the six terminals 1, 2, 3, 5, 6, and 7, but the remaining terminals 7 because the routes of the terminals 1, 2, 3, 5, and 6 have already been determined. Pay attention to. And
One branch is made from the terminal 4 to the terminal 7.

(5) The terminal 5 can communicate with the three terminals 1, 4 and 9, but focuses on the remaining terminal 9 because the routes of the terminals 1 and 4 have already been determined. Then, one branch is performed from the terminal 5 to the terminal 9. (6) The terminal 6 can communicate with the four terminals 3, 4, 7, and 8, but does not branch because the routes of the terminals 3, 4, 7, and 8 have already been determined.

(7) The terminal 8 can communicate with the two terminals 3 and 6, but does not branch because the routes of the terminals 3 and 6 have already been determined. (8) The terminal 7 can communicate with the four terminals 4, 6, 9, and 10, but focuses on the remaining terminal 10 because the routes of the terminals 4, 6, and 9 have already been determined. Then, one branch is made from the terminal 7 to the terminal 10.

(9) Since the connection paths for all the wireless terminals have been formed by the above series of processing, the processing ends. Similarly, a basic delivery route corresponding to another wireless terminal is configured according to the above-described flow.

When there are a plurality of small-scale networks constituted by communication between the PHS slave units and these small-scale networks are located at a long distance from each other, a plurality of small-scale networks are provided only by the PHS inter-slave unit communication function. It is not possible to connect large networks in a chain. That is, information cannot be shared between a plurality of small networks.

In order to realize this, it is necessary to connect the small networks over a long distance by some method. Therefore, when the wireless terminal described in the present invention is a PHS terminal, the above-described problem is solved by providing a communication mode switching function for automatically switching the inter-machine direct call mode to the public mode or the private mode.

For example, there is a method of switching the communication mode using an "AT command" (a control procedure determined for controlling a communication device such as a modem from a personal computer). Generally, when the modem receives the AT command, it returns the result as a “result code”.

At this time, an AT command for setting the system state of the PHS terminal is input, and an AT command for displaying the system state is input, and then the result code is stored. This process is repeated until the value of the result code becomes the desired communication mode. This series of processing is automatically repeated.

Thus, within each communication sector, a network is constructed by communication between slave units, and the connection between communication sectors can be established in the public or private mode. Here, there is a method of connecting between communication sectors between representative terminals in each communication sector. In this case, each representative terminal determines a delivery route in each communication sector by the method described above, and performs information delivery based on the delivery route by communication between slave units.

After completing the delivery to all the wireless terminals with which the representative terminal can communicate, the representative terminal automatically switches its own communication mode from the direct communication mode between handset units to the public or private mode by the above-described method. And a state where communication can be performed between the representative terminals. After that, information is shared between the representative terminals.

The representative terminal that has completed the information exchange may automatically switch the communication mode again to the direct communication mode between slave units and prepare for communication between slave units in each communication sector again. As described above, by using various communication modes together, it becomes possible to develop a regional network constructed by communication between slave units into a wide-area network.

[0069]

As described above, according to the present invention,
A representative terminal plays a central role, requests each wireless terminal to search for communicable peripheral terminals, and aggregates the search results. A relay route, that is, a delivery route can be determined. As a result, there is an advantage that a data communication network can be constructed ad hoc not only indoors but also outdoors.

If the present invention is utilized in a specific area, a circular material such as a “circulation version” can be distributed electronically. Further, if the present invention is applied to a vending machine, an electric or gas meter, it can be remotely operated, and can be used as a data collection system for collecting fee information.
