TECHNICAL FIELD The present invention relates to a network connection method of connecting a mobile communication terminal to the network,
In particular, the present invention relates to a technique which is effective when applied to a network connection method for performing a connection according to a user's usage form when connecting to a network from a mobile communication terminal.

[0002]

2. Description of the Related Art With the development of communication technology and standardization of various communication standards, mobile communication devices and terminals, such as mobile phones and terminals with a PHS function, have been widely used. One of the usage modes of these mobile communication terminals is that a user of a certain network uses the network when accessing the network from a destination. Access from a destination by the mobile communication terminal is performed by connecting to the network via an access point provided by the network.

[0003] The above-mentioned access point is a device which can accept a connection from the outside via a telephone line or the like, is mainly set in a computer device, and generally exists in a plurality in a network. The access point number is an ID of an access point represented by a telephone number.

[0004] By accessing in this way, it can be used via a network in the same manner as in the conventional internal connection. However, an information processing apparatus to be used (hereinafter referred to as a machine)
Depending on the logical connection position, operation status, and traffic status in the network, there may be a problem in processing and transfer speed.

[0005] Conventionally, only keeping the connection status of the machines connected in the network optimal has been considered, and no optimization regarding the connection between the mobile communication terminal and the network has been considered. The following is an example of the method.

(1) “Network system automatic construction / reconstruction method” in JP-A-4-114532 (2) “Network management support system” in JP-A-5-250296 (1) Network system automatic construction / reconstruction The rebuilding method rebuilds the network system group once built according to the node operation status and the network system operation status so that the network system can be maintained in an optimal configuration.

The network management support system of (2) makes it possible to maintain the network in an optimum configuration by making a connection change proposal of the machine based on the transmission data amount and transmission destination data of the machine connected to the network. It is.

[0008]

However, in the above-mentioned conventional techniques, optimization construction is performed for an information processing apparatus directly connected to a network, and the conventional technique is used for network connection using a mobile communication terminal. When applied, the following problems arise.

(1) Failure to connect to access point: Depending on the settings and the type of line contract, there are access points that cannot accept a plurality of accesses at the same time. When connecting to a network using such an access point from a mobile communication terminal, if the access point is already connected to another mobile communication terminal, new access cannot be accepted and the mobile communication terminal Will fail to connect to the network. In order to save the trouble of reconnection and the waiting time for connection, means for avoiding connection failure due to occupation of another terminal access point is required. However, there is no such means in the prior art, and there is a problem that the retry must be performed until the connection is successful.

(2) Variation in transfer rate and connection amount due to movement of mobile communication terminal: In a usage mode in which a mobile communication terminal is used to connect to a network from a destination,
Since the physical distance between the access target machine in the network and the mobile communication terminal changes due to the movement, a difference occurs in the transfer speed and the connection amount depending on which access point is used. When connecting to the network from the mobile communication terminal in such a situation, if the distance between the mobile communication terminal and the access point is short and the connection status between the access point and the access target machine is appropriate,
Transfer rates and connection costs are reasonable. Here, if there is a distance between the mobile communication terminal and the access target machine,
If you use an access point near the mobile communication terminal, the connection route in the network will be inappropriate and the transfer speed may be slow.If you use an access point near the access target machine, the connection fee will be high. Become. Therefore, means for determining an appropriate access point according to the destination of the mobile communication terminal and the needs of the user is required. However, the prior art has no such means, and has a problem that an appropriate access point must be selected based on experience.

SUMMARY OF THE INVENTION The present invention has been made to solve these problems, and an object of the present invention is to reduce the number of connection failures from a mobile communication terminal and to provide mobile communication according to a user's usage pattern. It is an object of the present invention to provide a technology capable of establishing a connection between a terminal and a machine to be accessed.

Next, a processing procedure at the time of connection from the mobile communication terminal 107 to the internal network 105 will be described with reference to the flowchart of FIG.

First, the mobile communication terminal 107 collects connection information as shown in FIG. 3 every time a connection is attempted.
Further, the network management system 101 stores information as shown in FIG. 2, and based on the information and the data of the connection information from each mobile communication terminal 107, a totaling result as shown in FIG. The calculation data as shown in FIG.

For connection from the mobile communication terminal 107 to the internal network 105, first, the user of the mobile communication terminal 107 makes a call from the mobile communication terminal 107 to an access point (step 701). Next, the success or failure of the connection to the access point is obtained (step 702). If the connection is successful, the process from step 703 is performed, and if the connection is unsuccessful, the processes from step 708 are performed.

In step 703, the mobile communication terminal 107 transmits the collected connection information (FIG. 3) to the network management system 101.

Thereafter, the mobile communication terminal 107 extracts, from the network management system 101, information requested by each mobile communication terminal 107 from the calculation data shown in FIG. 6 based on the priority designation table shown in FIG. The calculation data (a specific example is shown in FIG. 8) is received (step 70).

13 is a display example of calculation data displayed in step 703 when the user name of D is “user161” and the current location of the mobile communication terminal is Kawasaki.

In this example, mobile communication terminal number 1
Although the case of the 6-D user name “user161” has been described, if the same mobile communication terminal has a different user (user name “user162”), the distance between the mobile communication terminal and the access point is short. Since the high connection success rate is given priority over the above, the display order is different from that in FIG.

Further, if the user of the mobile communication terminal number 23-C has the user name "user238" and the access target machine is W
In the case of S1, the access point existing in the same segment as or adjacent to the access target machine WS1 is searched from the logical connection information received from the network management system 101, and the result (in this case, WS2) is displayed.

Next, a procedure for supporting the selection of an appropriate access point when the mobile communication terminal 107 connects to the internal network 105 using the calculation data (FIG. 8) received from the network management system 101 will be described.

FIG. 9 shows a network management system 101.
10 is a flowchart for explaining a process of selecting an access point by using calculation data received from a computer.

First, the user of the mobile communication terminal 107 inputs the current location 309, the access target machine name 307, and the user name 308 to the mobile communication terminal 107 (step 90).
1).

Next, the mobile communication terminal 107 stores a priority order designation table (FIG. 5) relating to connection conditions such as the success / failure of connection and the amount of connection required in advance and various data received from the network management system 101. Based on the data, data that satisfies the conditions specified by the user is searched (step 902). For example, mobile communication terminal number 16
In the case of the user name “user161” of −D, since the connection success rate and the short distance between the mobile communication terminal and the access point are specified in the priority specification table shown in FIG. The calculation data whose specified item matches the condition is searched from the calculation data class.

Thereafter, the calculated data retrieved in step 902 is displayed on the display device of the mobile communication terminal (step 903).

The user selects an access point with reference to the calculated data retrieved and displayed in step 903. Alternatively, a connection request is automatically made from the mobile communication terminal 107 to the access point that matches the condition most among the calculated data displayed in step 903 (step 904).

As a result, it is possible to select an access point having a high connection success rate, so that connection failure can be avoided and labor and time loss associated with reconnection can be saved.

Further, since the priority order can be specified, it is possible to select not only an access point having a high connection success rate but also an access point which is suitable for a user's usage mode such as emphasis on cost and transfer speed.

The network management system 101
Holds a threshold table having thresholds of calculated data for keeping the network optimal, and checks the calculated data to detect a decrease in the transfer speed or connection success rate at each access point on the network. By holding a cause / measure determination table indicating the cause and the measure, the cause can be investigated and the measure can be taken.

Yes, processing such as display on the display device of the network management system, notification to the administrator, and notification to the user is specified.

According to FIG. 10, in the connection success rate table, when the average connection success rate is less than 60%, the success rate is displayed on the display device of the network management system 101, and when the average connection success rate is less than 40%, the administrator is displayed. A mail is sent to inform the administrator of the decrease in the success rate, and if it falls below 20%, a cause and countermeasure is searched from a cause / countermeasure determination table in FIG. Specified.

FIG. 11 shows a cause / measures determination table when the threshold value is exceeded. This is the network management system 10
1 is set in advance.

An item name 1101 shown in FIG. 11 indicates which item of data in the network management system 101 is to be processed when the threshold is exceeded. Criteria 1102
Is a condition item for determining the cause and countermeasure when the threshold value is exceeded. The cause 1103 indicates what seems to be the cause of exceeding the threshold. The countermeasure 1104 indicates a countermeasure method for not exceeding the threshold.

Next, the processing procedure for detecting the state of performance degradation at the access point using the calculation result (FIG. 4) and the calculated data (FIG. 6) in the network management system 101 and supporting the countermeasures will be described with reference to the flowchart of FIG. explain.

First, the network management system according to the threshold table (FIG. 10)
A threshold value check is performed on various calculation data (FIG. 6) stored in the storage unit 01 (step 1201).

Next, the result of the threshold check performed in step 1201 is checked, and if there is data exceeding the threshold, the process proceeds to step 1203 (step 1202).

The data exceeding the threshold value whose existence has been confirmed is specified in the processing item 1004 of the threshold value table (FIG. 10), such as display on the network management system 101 and notification to the administrator by mail. Perform the processing that When a measure search is instructed in the process item 1004, the cause 1103 of the performance degradation and the measure 1104 are determined using the cause / measure determination table (FIG. 11), and a measure is taken (step 1203).

Thus, by performing a threshold check on the data calculated by the network management system, it is possible to support the connection to the optimal access point for the user at the time of connection, and to detect the performance degradation at the access point and take measures against it. Support can be provided, and network optimization can be achieved.
