DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a communication processing system for mobile communication, and more particularly to a communication processing system for mobile communication that can use a mobile communication terminal over a wide area even with a small number of base stations. About the system.

[0002]

2. Description of the Related Art In mobile communication, since communication is possible while moving, communication with a terminal requires radio communication by radio waves. Conventional mobile communication system,
For example, in a system of a mobile phone or a mobile phone with many users, a small zone configuration in which a range in which a radio wave can reach and a communication is narrowed in order to effectively use a radio wave and perform as much communication as possible is generally used. . A base station is located in each zone, so that the radio wave of the mobile terminal can reach the base station serving that zone at any position within a certain zone, and the mobile terminal moves to the next zone. if,
The communication destination of the mobile terminal can be switched so as to connect to a base station serving the zone.

Here, when a mobile terminal communicates with a partner terminal, the mobile terminal first sends a connection request. Then, the mobile terminal is connected to the base station in the zone in which the mobile terminal is located, and the base station searches the database in which the location information is registered in the connection request sent, and transmits the connection request to the base station in the zone to which the partner is located. To transfer through. The base station to which the connection request has been transferred broadcasts the connection request and calls the other terminal. When the other party answers, the mobile terminal can communicate.

[0004]

In wireless communication with a terminal in conventional mobile communication, a base station and a terminal directly communicate with each other. Since base stations are installed for each zone, it is necessary to install many base stations to enable mobile communication in a wide area. Therefore, there is a problem that the cost for installing the base station is enormous in order to expand the area where mobile communication is possible.

[0005] The present invention has been made in view of the above points, and it is an object of the present invention to provide a communication processing system for mobile communication that enables mobile communication in a wide area without increasing the number of base stations installed. Aim.

[0006]

SUMMARY OF THE INVENTION In order to solve the above problems, the present invention provides a mobile communication system in which a mobile terminal can communicate with another terminal via a base station connected wirelessly. In the communication processing system, there is provided a communication processing system for mobile communication, wherein the terminal includes relay processing means for performing a relay process of communication of another terminal.

According to such a communication processing system for mobile communication, individual terminals perform the relay processing that has been entirely performed by the base station. That is, when a connection request is transmitted from a nearby terminal, the relay processing unit of each terminal transmits the connection request to another nearby terminal. This process of relaying a connection request transmitted from a neighboring terminal is repeated by a plurality of terminals, and is performed until the connection request reaches the base station. As a result, even if the terminal that has transmitted the connection request is not within the service area covered by the base station, the connection request can reach the base station.

[0008]

Embodiments of the present invention will be described below with reference to the drawings. First, the outline of the present invention will be described first.

FIG. 1 is a diagram showing the principle configuration of the present invention. In this figure, a transmitting terminal 1, a plurality of relay terminals 2a, 2b, 2c, and a receiving terminal 3 are shown as mobile communication terminals, and these terminals can be wirelessly connected. Base station 4
a and 4b, and a position information database 5 for holding and managing the position information of the terminal. Here, each terminal has a function of performing a relay process, among which at least the relay terminal 2b exists within the service area of the base station 4a, and the relay terminal 2c is connected to the base station 4b. It is assumed that it exists in the service area. Each base station 4a, 4b
Are connected to each other by a fixed communication line 6, and are also connected to the position information database 5 so as to obtain information on the base station in the area to which the connected terminal belongs.

According to the communication processing system for mobile communication of the present invention, first, when the transmitting terminal 1 transmits a connection request message to the receiving terminal 3, the nearby relay terminal 2a transmits the connection request message. receive. Then, the relay terminal 2a relays the connection request message of the transmission terminal 1 and retransmits the message. The retransmitted connection request message is transmitted to the relay terminal 2a.
Is received by the relay terminal 2b located near the terminal. Since the relay terminal 2b exists in the service area of the base station 4a, the connection request message of the transmitting terminal 1 that has been received is received by the base station 4a. In this way,
The connection request transmitted from the transmitting terminal 1 is successively relayed to the relay terminals 2a and 2b, and reaches the base station 4a. At this time, each of the relay terminals 2a and 2b exchanges information indicating that the connection request of the transmitting terminal 1 has been relayed and information indicating which relay terminal has received the connection request and transferred to which relay terminal. Hold for a predetermined time.

Next, upon receiving a connection request from the transmitting terminal 1 to the receiving terminal 3, the base station 4a accesses the position information database 5 based on the information of the connection destination, and Get information. The base station 4a specifies the base station 4b in the area to which the receiving terminal 3 belongs based on the acquired position information, and transmits the connection request message of the transmitting terminal 1 to the base station 4b via the communication line 6. I do.

The base station 4b is connected to the transmitting terminal 1 by the base station 4a.
When the connection request message is received, the connection request message is transmitted to the nearby relay terminal 2c. The relay terminal 2c receives the connection request message from the transmission terminal 1 and transmits the message to another relay terminal. The base station 4b also performs relay processing by the relay terminal, and repeats this relay processing until it reaches the receiving terminal 3. Also at this time, all the relay terminals including the relay terminal 2c receive information indicating that the connection request of the transmitting terminal 1 has been relayed, and from which relay terminal the connection request has been received and transferred to which relay terminal. The information on whether the operation has been performed is held for a predetermined time. Through this series of processing, a relay route connecting the transmitting terminal 1 and the receiving terminal 3 is established. Then, a relay route establishment notification is sent from the receiving terminal 3 to the transmitting terminal 1 by going up the relay route. When the relay route establishment notification is received and the relay route is established, communication between the two can be performed using the relay route. Also, in each relay terminal, if the relay terminal establishment notification is not received from the receiving terminal 3 even after the predetermined time has elapsed, the relay terminals are the transmitting terminal 1 and the receiving terminal 3. And the held relay information is discarded.

As described above, since the mobile communication terminal itself performs the relay processing, it is possible to greatly reduce the number of base stations that have performed the relay processing and greatly expand the service area. .

Next, an embodiment of the present invention will be described with reference to a PHS (personal service) which is an extended version of a digital cordless telephone.
al handyphone system).

FIG. 2 is a diagram showing an example of the configuration of a PHS telephone. The illustrated PHS telephone 10 further includes a relay processing unit 15 in addition to a normal configuration including a reception unit 11, a transmission unit 12, an antenna 13, and a call processing unit 14. This relay processing unit 15 has a relay information storage unit 16.

The relay information storage unit 16 stores source and destination information for recognizing a telephone that has issued a connection request, connection destination and destination information for recognizing a destination telephone, and information for recognizing a PHS telephone that has been relayed up to now. , Relay destination address information for recognizing the telephone to which the connection request has been transferred, relay destination information for recognizing the telephone to which the connection request has been transferred, and information indicating that the PHS telephone 10 is performing a relay process. And relay flag information for setting whether or not.

Here, it is assumed that the PHS telephone 20 transmits the connection request, and the PHS telephone 10 is a telephone that relays the connection request of the PHS telephone 20 to the PHS telephone 30.
Next, the connection request of the PHS telephone 20 is sent to the PHS telephone 10.
How the relay processing unit 15 of another PHS telephone 3
The operation of transferring data to 0 will be described.

First, the PHS telephone 20 of the connection request transmission source
In such a case, a normal calling process such as inputting a telephone number of a call partner is performed using the functions of the call processing unit and the calling unit. When a connection request is transmitted through an antenna, a nearby PHS telephone 10 accepts the connection request. Although a plurality of PHS telephones receive the transmitted connection request, preferably, at the first stage of the individual relay processing performed with each PHS telephone, the PH of the connection request source is
Select the PHS telephone 10 that has a sufficiently high level of the radio wave received by the S telephone, that is, the PHS telephone 10 that is sufficiently close in distance to the PHS telephone 20 and can reliably perform the relay process. become.

In the relay processing unit 15 of the PHS telephone 10,
The relay flag information is set in the relay information storage unit 16, and the source destination information for recognizing the PHS telephone 20 and the connection destination information for recognizing the connection request destination telephone are written. At this stage, the relayed terminal information, the relay source destination information, and the relay destination information are blank. In this example, since the PHS telephone 10 is a telephone that relays first, the relay source destination information and the relayed terminal information are left blank. The relay processing unit 15 further activates a time counter (not shown) simultaneously with the setting of the relay flag information.

Next, the relay processing unit 15 of the PHS telephone 10
Transmits a connection request for the PHS telephone 20 via the transmission unit 12 and the antenna 13. Again, multiple PHS
The telephone receives the connection request of the PHS telephone 20, but the PHS telephone 30 that can perform the relay processing reliably is selected as the PHS telephone of the relay destination. At this time, the PHS telephone 20 also receives the connection request, but the relay processing unit 15 checks the source address information stored in the relay information storage unit 16 and removes the information from the relay destination. Relay PHS
When the telephone 30 is determined, the relay processing unit 15 of the PHS telephone 10 writes information for recognizing the PHS telephone 30 that has transferred the connection request to the relay destination information of the relay information storage unit 16. On the other hand, in the relay processing unit of the PHS telephone 30, in the relay information storage unit, the relay flag information, the source destination information, the connection destination information, the relayed terminal information,
And the relay source destination information is written. Here, the PHS telephone 30 is included in the relayed terminal information and the relay source destination information because the PHS telephone 30 is the second relay terminal.
Only the information recognizing 0 is written.

In this manner, a plurality of PHS telephones sequentially perform the relay processing until reaching the nearest base station. At this time, the relay processing unit transmits the source address information and the relayed information in the relay information storage unit. Refer to the terminal information, remove the PHS telephone recorded there from the target of the relay destination,
The PHS telephone to be relayed is determined.

However, if there is no connection before arriving at the base station, the PH that has relayed to that point
PHS phone 2 as the source by following S phone in reverse
Notify 0. In this case, the relayed PHS telephone receives the notification that there is no connection destination and clears the relay flag information in the relay information storage unit. Also, when the time counter of the relay processing unit has passed a predetermined time set in advance, the relay processing unit of the PHS telephone determines that the relay route establishment has failed, and clears the relay flag information of the relay information storage unit. I do. The source PHS telephone 20 receives the notification that there is no connection destination, or starts the establishment of another relay route when a predetermined time has elapsed after the transmission of the connection request.

Further, in some cases, while the relay route is being established, before reaching the base station, the user may reach the PHS telephone of the connection partner. In such a case, there are a case where the relay route is established at that time and a case where the relay process is continued until the base station is reached. The former is a special case, for example, in which the connection destination is a telephone of a number registered in advance and not to be charged, and the latter is a general case.

The operation of the relay processing until reaching the base station in the area on the transmitting side has been described above.
After the connection request is relayed, the base station accesses the location information database to acquire the location information of the PHS telephone of the connection request destination, and connects to the base station in the area to which the PHS telephone of the connection request belongs. The request is forwarded, and a connection request is issued from the base station. Even in the area on the receiving side, the same relay processing for establishing a relay route is performed by a plurality of PHS telephones until the base station arrives at the connection request destination PHS telephone.

The relay processing unit may be operated in parallel with the call processing unit in one PHS telephone. That is, when a certain PHS telephone is in a call by the function of the call processing unit, the relay processing unit
The relay processing of the HS telephone can be performed simultaneously. In addition, the relay processing may simultaneously perform the relay processing of a plurality of other PHS telephones. At this time, the relay information storage unit of the relay processing unit has a plurality of storage areas, and when performing relay processing of another PHS telephone, the relay flag information is checked and the relay flag is set. No storage space is used.

Further, if the establishment of the relay route in the area of the transmitting side and the receiving side is unsuccessful, other mobile communication means, for example, a service network of another PHS, or a car / cell phone having a more reliable connection. May be connected to this service network. Of course, in this case, it is necessary to simultaneously subscribe to the service of such another mobile communication means.

Note that there is a possibility that a plurality of relay routes may be established between a plurality of PHS telephones and the base station, but only one is actually used as the relay route. Here, if the relay route has already been established when a certain PHS telephone starts transmitting the connection request, the processing time for establishing the relay route becomes unnecessary. Hereinafter, a case will be described in which a relay route is established in advance, and when a connection request message of a PHS telephone is transmitted, a connection is made to a base station using the relay route established in advance.

FIG. 3 is an explanatory diagram showing how a connection request transmitting side base station establishes a relay route. In this figure, a plurality of PHS telephones 41a are located near a certain base station 40.
41m, a plurality of PHS telephones 42a to 42n exist near the PHS telephone 41a, and a plurality of PHS telephones 43a to 43o exist near the PHS telephone 42a.
Assume that exists.

Here, when a relay route to the base station 40 is established in advance, first, at a fixed time interval from the base station 40, information indicating that this information is transmission information from the base station, Nearby PHS phones 41a-41m
Broadcast all at once. Then, the PHS telephone 41a ~
For example, the PHS telephone 41a in the 41m is a base station 4
0 from other PHS telephones 42a-4
2n, and turns on a flag indicating that the information has been received.
The transfer destination of the connection request when a to n send the connection request is set to the base station 40.

Similarly, for example, PHS telephone 42a
When the transmission information of the base station 40 is received from the PHS telephone 41a, the transmission information is transmitted to the other nearby PHS telephones 43a to 43a-4.
3o, and at the same time, turns on a flag indicating that the information has been received.
The setting is made such that the transfer destination of the connection request when a to 43o issue the connection request is the PHS telephone 41a. By repeating this process for other PHS phones,
Several relay routes to the base station 40 are established. Further, when each PHS telephone receives the transmission information from the base station 40, it checks whether or not the same information has been received before by using a flag, and if the same information has been received, does nothing.

By the above processing, the relay route between each PHS telephone and the base station is radially established around the base station. In this state, for example, when the PHS telephone 43a attempts to transmit a connection request message, the base station 40
Since the relay route up to this point is established, the transfer destination of the connection request message set in each of the PHS telephones existing during the route is traced in order, so that the base station 40 can be reached by the shortest route. . For example, the PHS telephone 43a, according to the information of the PHS telephone of the transfer destination of the connection request message set for itself,
A connection request message is transmitted to the PHS telephone 42a. PHS
Upon receiving the connection request message, the telephone 42a starts the relay process, and sets the transfer destination P of the connection request message set in its own device.
The connection request message is transmitted to the PHS telephone 41a according to the information of the HS telephone. The PHS telephone 41a receives the connection request message, starts relay processing, and transmits a connection request message to the base station 40 according to the information of the PHS telephone to which the connection request message is set, which is set in the PHS telephone 41a.

FIG. 4 shows a state in which a relay route from the base station is established.
FIG. 4 is a diagram illustrating an example of route information set in an HS telephone. In the relay processing unit of the PHS telephone, in the storage unit,
It has route information 50 that is set when a relay route is established based on transmission information from a base station. The route information 50 includes reception flag information indicating that the transmission information from the base station has been received, base station identification (ID) information indicating which base station the transmission information is from, and transmission information of the base station. Connection request transfer destination information indicating which PHS telephone has been relayed, that is, to which PHS telephone the connection request of the PHS telephone received from the own device or another device is to be transferred. It is supposed to be.

By setting the route information 50, a relay route is established in advance by the base station in advance,
Thereafter, each PHS telephone performs a relay process using the established relay route. An example of this case is shown below.

FIG. 5 is an explanatory diagram showing an example of establishing a relay route from a base station. In this figure, there is a certain base station 60, and its base station identification information is, for example, “A
1 ". In the area of the base station 60, the base station 6
PHS telephones 71, 72, 73,
.. Exist, and these pieces of recognition information are, for example, “a
1 "," a2 "," a3 ",... Next, PHS telephones 71, 72, 7 which are these first generation repeaters are used.
Are PHS telephones 81, 82, 83,... Which are second-generation repeaters, and their recognition information is, for example, "b1", "b2", "b3", ...
And And PHS which is these second generation repeaters
Are present in the vicinity of the telephones 81, 82, 83,..., Which are third-generation repeaters, and their recognition information is, for example, “c1”,.

In the illustrated relay route establishment example, the base station 60
The broadcast information broadcast simultaneously from PHS telephones 71 and 7
2,73 receive. Next, the transmission information of the base station 60 is PH
S telephones 71, 72, and 73 are transmitted, for example, PHS telephone 81 is composed of three PHS telephones 71, 7
2, 73, the PHS telephone 82 receives from the PHS telephone 72, and the PHS telephone 83 receives from the PHS telephone 73. Further, these PHS telephones 81, 82, 83 are further connected to the base station 60.
Respectively, the PHS telephone 91 receives the transmission information of the base station 60 from the three PHS telephones 81, 82 and 83, for example. The establishment of the route performed in this way is continued, for example, up to the PHS telephone which receives the transmission information of the different base stations.

At this time, route information is set in each PHS telephone, and an example of the setting is shown in FIG. 6 for PHS telephones 71, 81, and 91. FIG. 6 shows the main P
It is a figure showing an example of setting of the route information of the HS telephone,
(A) shows the route information of the PHS telephone relayed by the first generation, (B) shows the route information of the PHS telephone relayed by the second generation, and (C) shows the route of the PHS telephone relayed by the third generation. Indicates information.

According to the route information set in the PHS telephone 81, as shown in (A), the reception flag information indicating that the transmission information from the base station 60 has been received is set to "ON,
1 ", the base station identification information is" A1 ", and the connection request transfer destination information is" A1 ". Note that "1" set in the reception flag information indicates that the relay is the first generation relay, and this value is referred to when transmission information from the base station is received. In other words, the transmission information from the same base station 60 may be received again via another PHS telephone, so in order to prevent this, if the received transmission information is from the same base station 60, it is set. Check the reception flag information to see if the same information is set. As an example of the check, for example, the transmission information may be accepted only when the relay generation is one generation before, and the transmission information of two generations before, the same generation, or the previous generation may be rejected. Also,
Since the PHS telephone 81 is a first-generation repeater, there is only one piece of route information.

The PHS telephone 82 is a PHS telephone 71,7.
Since the transmission information of the base station 60 is received from 2, 73,
As shown in (B), three pieces of route information are set. That is, the same information “ON, 2” and “A1” are set for the reception flag information and the base station recognition information, but “a1” and “A1” are set for the connection request transfer destination information.
“A2” and “a3” are set. Similarly, in the PHS telephone 83, as shown in (C), three pieces of route information are set, and each reception flag information contains "ON, 3".
However, “A1” is included in each base station identification information, and “b1”, “b2”,
“B3” is set.

When the route information is set in advance as described above, it becomes possible to immediately establish a relay route to the nearest base station when a PHS telephone on the relay route issues a connection request. . For example, P
When transmitting a connection request, the HS telephone 91 first obtains connection request transfer destination information whose reception flag information is “ON” from its own route information. In this example,
Since three pieces of route information are set, any one is selected and a connection request is transmitted to the PHS telephone. Here, for example, it is assumed that a connection request is transmitted to PHS telephone 81 whose recognition information is “b1”. Then, the PHS telephone 81
Receives the connection request of the PHS telephone 91 and starts the relay processing. This PHS telephone 81 also refers to its own route information, specifies the next PHS telephone that can be relayed, and sends a connection request for the PHS telephone 91 to the PHS telephone. Here, for example, the P of the recognition information “a1”
It is assumed that a connection request is transmitted to the HS telephone 71. And
The PHS telephone 71 receives the connection request of the PHS telephone 91 and transmits the request to the base station 60.

As described above, each PHS telephone which has received the connection request performs the relay processing based on the connection request transfer destination address information, and thereby the PHS telephone 91 which has transmitted the connection request.
The shortest route from to the base station 60 is established in a short time.

The PHS telephones 81 and 91 hold a plurality of pieces of route information and use one of them for relay processing. In this case, the route information used for the relay processing can be used as the relay destination information of the active system, and the other route information can be used as the relay destination information of the standby system. Therefore, during a call via the relay route established by the relay destination information of the active system, the relay function may be moved to a location where the relay PHS telephone cannot be relayed on the relay route, or the power may be turned off. Is lost and the communication becomes impossible, the relay processing unit can immediately reset the relay route based on the relay destination information of the standby system and continue the communication on the standby route. For example, in the relay route illustrated in FIG. 5, the PHS telephone 91 issues a connection request, and the PHS telephone 81 and the PHS telephone 71 relay to establish a relay route to the base station 60. Suppose you are talking by. At this time, for example, if the PHS telephone 81 cannot be relayed,
The telephone 91 immediately switches the relay destination to the PHS telephone 82, for example.
, And a route for connecting to the base station 60 via the PHS telephone 72 is established, and the call is continued on this route.

Further, in the above example, when a relay route is established in advance by the base station, a plurality of pieces of relay destination information are set. It is passive. On the other hand, for example, when a PHS telephone is adopted as an active repeater, the repeater transmits information for securing a standby system and actively secures another relay route in advance. You can also.

Lastly, a case will be described where a base station receives a connection request and establishes a relay route from the base station to a connection destination. Received a connection request from another base station,
Alternatively, even in the base station which has received the connection request, a process of setting a relay route at a predetermined time interval is performed in advance in preparation for a PHS telephone belonging to the area of the base station to relay the connection request. At this time, according to the method of establishing a relay route shown in FIG.
Simultaneously broadcast to the S telephone. However, if the base station has received the connection request, the connection request is also included in the information transmitted from the base station.

That is, in this case, the base station simultaneously performs an operation of establishing a relay route in advance and an operation of searching for a PHS telephone to be connected based on the received connection request. Therefore, the base station performs the process of establishing the relay route at a fixed time interval, but if the time interval is set long, it will also perform the process at the timing when a connection request comes.

When a certain base station receives a connection request from another base station or directly receives a connection request, the base station transmits information for establishing a relay route including the connection request. The information is the PHS in the area of the base station.
The PHS telephone receives the connection destination information from the received information and compares it with its own destination information. As a result of the comparison, if the connection destination information does not match the own destination information, the process of establishing the relay route is continued as it is. If the destination information matches the destination information, the process of establishing the relay route continues, and the relay processing unit traces the route information and establishes the relay route to the base station. A relay route establishment notification is returned to the PHS telephone that has transmitted the connection request. Thereafter, the call processing unit P
A call will be made with the HS telephone.

[0046]

As described above, in the present invention, the mobile communication terminal itself is configured to perform the relay processing of another terminal. Therefore, the load of the relay processing on the base station can be significantly reduced, and a mobile communication network in which the number of base stations to be installed can be significantly reduced can be constructed, and the cost of the mobile communication processing can be reduced. Can be greatly reduced. Further, when a new service area is expanded, the number of base stations can be reduced, or existing base stations can be reduced.

The relay processing unit for performing the relay processing may be provided not only in a mobile communication terminal but also in a digital cordless telephone used at home, for example. So you do n’t have to worry
It is possible to perform relay processing at all times. Further, the present invention can be applied not only to a telephone but also to a portable information terminal capable of wireless communication.
