The access point 1000 holding the hash value of the receiving terminal among the plurality of access points 1000 included in the communication network provides access point information corresponding to the received hash value to the second access point 1000b connected to the calling terminal. can do.

Accordingly, the second access point 1000b may acquire access point information about the access point 1000 connected to the receiving terminal.

According to an embodiment of the present invention, connecting a source terminal and a destination terminal (S240).

According to an embodiment, the second access point 1000b may request connection between the receiving terminal and the calling terminal based on the acquired access point information.

Alternatively, according to an embodiment, the calling terminal may obtain access point information from the second access point 1000b, and may request connection with the receiving terminal based on the obtained access point information.

Referring to FIG. 6, the second access point 1000b may obtain the IP address of the first access point 1000a to which the first terminal 2000a, which is a receiving terminal, is connected based on terminal information. Also, the second access point 1000b may request connection of the first terminal 2000a and the second terminal 2000b to the first access point 1000a based on the IP address of the first access point 1000a.

8 is an environment diagram illustrating handover according to an embodiment of the present invention.

Referring to FIG. 8, when the terminal 2000 is a movable terminal, the terminal 2000 may move and the location of the terminal 2000 may be changed. Also, as the terminal 2000 moves, the access point 1000 connected to the terminal 2000 may change.

For example, as shown in FIG. 8, the first terminal 2000a connected to the first access point 1000a may move and be connected to the second access point 1000b.

The second access point 1000b may generate a hash value for the first terminal 2000a when the first terminal 2000a is moved and newly connected.

In addition, the second access point 1000b transmits the information of the second access point 1000b to the access point 1000 that holds the access information of the first terminal 2000a to obtain a hash value for the first terminal 2000a. It may request to update the stored access point information matched with.

According to some embodiments of the present invention, the second access point 1000b stores the hash value for the first terminal 2000a and the access information for the second access point 1000b and the hash value for the first terminal 2000a. It can be transmitted to another stored access point (1000).

In addition, when the other access point has a hash value for the first terminal 2000a, the second access point 1000b stores access information matched with the hash value for the first terminal 2000a and stores the access information of the second access point 1000b. You can request to be updated with access information for.

Therefore, among the plurality of access points 1000 included in the communication network, the access point 1000 having the hash value for the first terminal 2000a is matched with the first terminal 2000a to obtain the stored access information ( 2000a) may be updated with access information for the second access point 1000b newly connected.

9 is an environment diagram showing user departure according to an embodiment of the present invention.

As illustrated in FIG. 9, the first terminal 2000a connected to the first access point 1000a may move and deviate from the communication range A of the first access point 1000a. For example, when the first terminal 2000a deviates from the communication range A of the first access point 1000a, the disconnected first terminal 2000a may terminate the communication connection of the first access point 1000a.

The access point 1000 performing the storage function can check whether the connection with the access point 1000 to which the terminal 2000 is connected is disconnected, and the connection with the access point 1000 to which the terminal 2000 is connected is disconnected. In this case, the connection information stored by matching the hash value and the hash value of the terminal 2000 from which the connection is terminated may be deleted.

According to some embodiments of the present invention, the access point 1000 may check whether the terminal 2000 corresponding to the stored hash value maintains a connection.

The access point 1000 performing the storage function may periodically check whether the terminal 2000 corresponding to the stored hash value maintains a connection. When the connection of the terminal 2000 corresponding to the stored hash value is terminated as a result of the verification, the access point 1000 storing the hash value of the terminal may delete the hash value and the access point information corresponding to the hash value.

According to some embodiments of the present invention, when the connection with the connected terminal 2000 is terminated, the access point 1000 stores a hash value and an access point stored in the access point 1000 that stores the hash value of the terminated terminal 2000. You can ask to delete the information.

In the above, the configuration and features of the present invention have been described based on the embodiments according to the present invention, but the present invention is not limited thereto, and it is understood that various changes or modifications can be made within the spirit and scope of the present invention. It will be apparent to those skilled in the art, and therefore, such changes or modifications are found to belong to the appended claims.
