Description

Apparatus and method for controlling ad hoc network configuration using mobile communication network {APPARATUS AND METHOD FOR CONTROLLING AD-HOC NETWORK CONFIGURATION BY USING MOBILE TELECOMMUNICATION NETWORK}

The present invention relates to an ad hoc (AD-HOC) network configuration method, and more particularly, to an ad hoc network configuration control apparatus and method for managing and controlling the authentication and group management / control functions for configuring an ad hoc network through a mobile communication network.

Ad-hoc (AD-HOC) network is a technology in which nodes dynamically configure and communicate with each other in an environment without an infrastructure such as a mobile communication network. In the existing ad hoc network, a specific node performs a master role to authenticate / control an access terminal and to manage an ad hoc access channel.

In general, the nodes constituting such an ad hoc network are mobile terminals, and thus there are limitations on battery capacity, central control unit, and memory performance. Therefore, when the master node manages the authentication and access channel for the entire ad hoc group, traffic is concentrated to the master node, which not only degrades the performance of the ad hoc network but also rapidly consumes the battery of the master node.

In addition, with the recent increase in the number of Wi-Fi (Wireless Fidelity, Wi-Fi) terminals, the number of Wi-Fi Access Points (APs) installed by service providers and individual users is increasing rapidly.

It is important to select a channel that does not cause interference because a plurality of Wi-Fi access points (APs) installed within the Wi-Fi propagation range cause radio channel interference to each other, thereby reducing wireless transmission capacity. However, since the ad hoc network can be configured over a large area, there is a problem that the Wi-Fi channel selected by the master node cannot be used due to the surrounding Wi-Fi AP interference in a node far from the master node.

Therefore, in order to optimize the performance of the Wi-Fi-based ad hoc network, it is necessary to identify all the Wi-Fi channels that interfere with the nodes constituting the ad hoc network, and analyze the optimal channel based on this to control the channel.

In addition, Wi-Fi technology has a disadvantage that the security is relatively weak compared to the mobile communication technology. Therefore, there is a need for a technology that can improve security when configuring an ad hoc network using Wi-Fi.

On the other hand, with the recent expansion of smartphones, various applications that can be used on smartphones are being developed. However, some users have illegally downloaded and used smartphone applications. In particular, there may be a problem of infringing the profits of the application developers and infringing the profits of the telecommunications companies.

Therefore, there is a need for a technology that blocks such illegally downloaded applications from accessing the ad hoc network.

In addition, in the existing ad hoc network, if the node moves out of the range of the ad hoc group, the ad hoc communication cannot be performed and the position of the ad hoc group cannot be determined, so in which direction, the ad hoc group can be accessed again. There is a difficult problem.

In order to solve the above problems, an object of the present invention is to provide an ad hoc network configuration control apparatus and method for managing and controlling the authentication and group management / control functions for configuring an ad hoc network through a mobile communication network.

4 is a diagram illustrating a method for creating an ad hoc network or accessing an ad hoc network through a mobile communication network according to an embodiment of the present invention.

When the ad hoc application program 240 is executed, the ad hoc node 200 drives the mobile communication module 220 to access the ad hoc management server 100 through the mobile communication network 400 (S100 and S102).

The ad hoc management server 100 can authenticate the use of ad hoc services through a mobile communication network 400 that can be accessed anytime, anywhere, and can fundamentally block the use of ad hoc services by illegal users, and through a mobile communication network 400 having superior security compared to Wi-Fi. By performing ad hoc service authentication, illegal use can be prevented.

The ad hoc management server 100 requests and analyzes the user information of the ad hoc node 200 and the ad hoc application information 240 requesting the use of the ad hoc service to the mobile communication authentication system 500, and then authenticates the use of the ad hoc service (S104). ).

The ad hoc node 200 authenticated by the ad hoc management server 100 drives the ad hoc communication module 210 to search for the presence of an ad hoc group using the ad hoc application program 240 (S106).

If there is an ad hoc group using the same ad hoc application 240 around the ad hoc node 200, the ad hoc node 200 determines whether to join the ad hoc group or create a new ad hoc group (S108, S110, S112).

When the ad hoc node 200 joins the existing ad hoc group, the ad hoc node 200 requests the ad hoc management server 100 to join the ad hoc group through the mobile communication network 400 and uses the ad hoc service (S114).

If a new ad hoc group is to be created, the corresponding node becomes the master node 200a of the ad hoc group, and the ad hoc management server 100 selects an optimal communication channel by analyzing the radio channel being used by the ad hoc nodes 200 nearby. It registers in (S116).

At this time, the master node 200a is the ad hoc group name, ad hoc service content, maximum number of users, ad hoc access password, whether the master node 200a is approved when ad hoc group access, ad hoc network address range, ad hoc network duration The information is registered in the ad hoc management server 100 through the mobile communication network 400 (S118, S120).

Thereafter, when the other ad hoc nodes 200 access the ad hoc group, the ad hoc network 300 uses the ad hoc service (S114).

After using the ad hoc service, the ad hoc application program 240 is terminated (S122).

When the ad hoc application 240 needs to manage the service use result, such as a game, the ad hoc node 200 before the ad hoc application 240 terminates the service use result through the mobile communication network 400 through the ad hoc management server ( 100 to save / manage and exit the ad hoc application 240.

When the ad hoc application program 240 is terminated, the ad hoc node 200 releases the connection with the ad hoc management server 100 and terminates the ad hoc communication module 210 to reduce battery consumption (S124).

FIG. 5 is a diagram illustrating a detailed flow of joining an ad hoc group in which a new ad hoc node is configured in FIG. 4.

When the new ad hoc node 200b approved for use of the ad hoc service from the ad hoc management server 100 wants to join the ad hoc group configured by the other ad hoc nodes 200, the ad hoc management server 100 is transmitted through the mobile communication network 400. Ad request to join the ad hoc at (S200).

The ad hoc management server 100 requests the master node 200a to approve connection of the new ad hoc node 200b when the node that has created the ad hoc group requests the approval of the master node 200a upon joining the ad hoc group (S202 and S204). .

When the master node 200a approves joining the new ad hoc node 200b, the new ad hoc node 200b joins the ad hoc group and uses the ad hoc service through the other ad hoc nodes 200 and the ad hoc network 300 ( S206, S208, S210).

After using the ad hoc service, the ad hoc application program 240 is terminated (S212), and the termination procedure is the same as described with reference to FIG. 4.

6 is a diagram illustrating a sequence of a method for creating an ad hoc network and accessing the ad hoc network through a mobile communication network according to an embodiment of the present invention.

As shown in FIG. 4, when the master node 200a executes the ad hoc application program 240, the master node 200a requests the ad hoc service use authentication to the ad hoc management server 100 through the mobile communication network 400. (S300).

The ad hoc management server 100 requests the mobile communication authentication system 500 to confirm whether the master node 200a is a user terminal subscribed to the ad hoc service and whether the application executed by the master node 200a is legally downloaded. (S302).

The ad hoc management server 100 receiving the subscription confirmation from the mobile communication authentication system 500 authenticates the use of the ad hoc service to the master node 200a (S304).

The master node 200a, which has been certified to use the service, requests the ad hoc group creation from the ad hoc management server 100 through the mobile communication network 400 and receives the ad hoc group creation approval from the ad hoc management server 100. Register information such as group name, ad hoc service content, maximum number of users, ad hoc access password, whether the master node 200a is approved during ad hoc group access, ad hoc network address range, ad hoc network duration, etc. in the ad hoc management server 100 (S306, S308, S310).

When the new ad hoc node 200b wishing to join the ad hoc group executes the ad hoc application 240, it is authenticated from the ad hoc management server 100 through the mobile communication network 400 similarly to the authentication procedure of the master node 200a. (S312, S314, S316, S318).

The new ad hoc node 200b receiving the ad hoc service use authorization from the ad hoc management server 100 searches for the ad hoc group, selects an ad hoc group to join, and requests the ad hoc subscription to the ad hoc management server 100 (S320, S322). .

The new ad hoc node 200b that has been approved to join the ad hoc group from the ad hoc management server 100 forms an ad hoc network 300 with the master node 200a as shown by a dotted line in FIG. 6 to the ad hoc network 300. Data is transmitted and received (S324).

When the new ad hoc node 200b using the ad hoc service terminates the ad hoc application program 240, the new ad hoc node 200b notifies the ad hoc group leaving the mobile communication network 400 (S326 and S328). Subsequently, the ad hoc management server 100 updates and manages the corresponding information (S330).

7 is a diagram illustrating ad hoc network interference by a Wi-Fi AP.

The channel change manager 130 receives the information on the use channel of the AP corresponding to the ad hoc node to access the ad hoc group and the information on the use channel of the ad hoc group from the ad hoc group manager 110 and receives the received channel information. The use channel of the ad hoc group may be changed so that an ad hoc node wishing to access the ad hoc group may access the ad hoc group without channel interference.

As shown in FIG. 7, when the ad hoc node 200 in the Wi-Fi AP coverage 600 using the wireless channel A is the master node 200a, the master node 200a is a usage channel of the ad hoc group. May be selected as the channel C without interference with the Wi-Fi AP coverage 600 using the wireless channel A.

In this case, the ad hoc nodes 200b in the Wi-Fi AP coverage 620 using the radio channel B may access the ad hoc group via the radio channel C to use the ad hoc service.

However, since the ad hoc node 200c in the Wi-Fi AP coverage 610 using the wireless channel C cannot use the channel C, it becomes difficult to access the ad hoc group due to channel interference when trying to access the ad hoc group. .

Therefore, in this case, the channel change manager 130 may change the use channel of the ad hoc group from channel C to channel D so that all the ad hoc nodes 200a, 200b, and 200c can access the ad hoc group. In addition, to solve this problem, as shown in FIG. 1, the ad hoc nodes 200 transmit the channel information being used by the neighboring Wi-Fi AP to the ad hoc management server 100 through the mobile communication network 400. In addition, the ad hoc management server 100 analyzes an optimal channel and negotiates with the master node 200a, and then changes the ad hoc communication channel of the entire ad hoc group.

8 is a diagram illustrating a sequence of a method for optimizing an ad hoc communication channel of an ad hoc group in an ad hoc management server through a mobile communication network according to an embodiment of the present invention.

As shown in FIG. 7, the master node 200a analyzes an ad hoc interference channel, selects an ad hoc channel of an ad hoc group, and registers the ad hoc channel with the ad hoc management server 100 through the mobile communication network 400 (S400, S402). ). At this time, the neighboring ad hoc channel information obtained through the ad hoc communication module 210 is also registered.

The new ad hoc node 200b wishing to participate in the ad hoc group generated by the master node 200a retrieves the ad hoc interference and channel information of the ad hoc group desired to participate and registers the ad hoc interference channel information through the mobile communication network 400. Request to join the ad hoc group (S404, S406).

The ad hoc management server 100 analyzes and derives an ad hoc channel capable of optimizing the transmission performance of the ad hoc group through the ad hoc interference channel information received from the master node 200a and the new ad hoc nodes 200b (S408).

After inquiring the master node 200a about whether to change the communication channel of the ad hoc group with the derived ad hoc channel, and when the master node 200a requests the change, the channel is sequentially sequentially from the master node 200a to the new ad hoc node 200b. The change request and confirmation procedure is performed (S410, S412, S414, S416, S418, S420, S422, and S424).

The master node 200a and all nodes in the ad hoc group can also change channels at the same time.
