It consists of technology.

In particular, location-based service technology is a platform for providing various technologies that are necessary foundations between mobile communication networks and application services of location-based services. These platform technologies are divided into access to external networks, location database construction, and location data server technology that processes real-time mass location information.

Based on these platforms, location-based services are initially expanding and developing into individual infrastructures, such as e-commerce, transportation, environment, and healthcare, according to the development of location technology and the advancement of services. As seen through the war, it can be said to be positioned as a strategic core technology for the future defense.

Since the IT industry has been active, services using location information, such as maps and logistics location tracking, have been provided through the Geographical Information System (GIS) and Global Positioning System (GPS). Location information is widely used in defense, environment, transportation and logistics. However, unlike conventional similar services, location-based services are of interest to the general public because location information is connected to mobile communication services, which are most popular in terms of communication infrastructure, to create various consumer-oriented services. Because it can.

However, the conventional location management technique using a mobile communication network independently operates independently from a sensor network including a sensor node to construct an independent sensor network to transmit sensing data of the sensor node and location information of the sensor node to a user. The location information of the conventional mobile communication terminal is the location information of the base station unit. In the case of a wide area base station having a radius of several tens of kilometers (km), an error occurs in the location information of the mobile communication terminal, and thus it is impossible to obtain accurate location information.

The cluster head 130 is superior to the sensor nodes 121, 122, and 123 in terms of computing power and storage capacity, and may be a slow moving or fixed node. In addition, a Zigbee module may be mounted for communication in the sensor network, and a Bluetooth module may be mounted according to an implementation environment.

The cluster 135 is a set of sensor nodes composed of the cluster head 130 and the plurality of sensor nodes 121, 122, and 123. The sensor nodes 121, 122, 123 in the cluster 135 may communicate with other sensor nodes 121, 122, 123 only through the cluster 135.

In addition, the cluster head 130 receives the sensing information from the sensor nodes 121, 122, and 123 and transmits the sensing information to the access node 140. The access node 140 may be a mobile node and may support a wireless ad hoc environment.

Meanwhile, the cluster head 130 may perform an additional function of aggregation of the sensing information as well as simply transferring the sensing information.

The access node 140 is a node having an interworking function with the mobile communication network and generally serves as a gateway of the sensor network.

Alternatively, the configuration may further include a global system for mobile communication (GSM) module.

More specifically, when the mobile communication base station 150 is configured according to the present invention, the access node 140 may be a mobile communication terminal. In this case, the mobile communication terminal may include a module capable of communicating with the sensor nodes 121, 122, and 123. It may be equipped with a dual mode mobile communication terminal.

The mobile communication network 160 is a core network including a base station controller, a mobile communication switch, a wired switch, a visitor location register (VLR) and a home location register (HLR). Enables connection to a communication network or a wired network. In addition, the Visitor Location Register (VLR) and the Home Location Register (HLR) manage subscriber information and location information of the mobile communication terminal to enable various location information services through the existing mobile communication network. .

5 is a flowchart illustrating a method for providing location information service according to the present invention.

First, location information of a sensor node is generated according to location information of a reference node (step 510). The 3D position information of the reference node may be obtained by a global positioning system (GPS) or by an input of an administrator. The position information of the reference node thus obtained is transmitted to the neighboring sensor nodes by periodical broadcasting.

More specifically, to generate the location information of the sensor node itself, the location information of the sensor node is generated based on the location information of the reference node and the information about the distance from the reference node. The distance from the reference node is obtained by accessing a distance measurement database using the index of the strength of the transmission signal of the position information received from the reference node. Distance measurement database based on signal strength is databased through sufficient implementation in advance. The distance from the reference node computed by this database becomes the concept of range to generate the position information of the sensor node itself with the position information transmitted from the reference node.

Referring to Table 1 above, the distances according to the strengths of the transmission signals which have been databased through sufficient implementation in advance are shown.

In this way, the position information of the sensor node itself is generated by combining the position information transmitted from the reference node together with the distance from the reference node calculated by the database.

That is, the database is referred to in advance by referring to the strength of the transmission signal transmitted by the reference node in the actual sensor network. The signal strength is indexed by referring to the signal strength. Then, the distance from the reference node is calculated by accessing a database according to the strength of the indexed transmission signal. The location information of the sensor node is obtained by combining the calculated distance and the location information of the reference node.

Table 2 is a message for transmitting the location information of the sensor node itself to the cluster head as an example of the location information transmission message to the cluster head of the sensor node. In the case of the cluster head, the position information of the sensor node is transmitted along with its own position information. That is, Table 2 shows an example of the sensor node, and in the present invention, the same may be applied to the process of transmitting the position information of the cluster head to the access node.

Next, location information of the sensor node is generated from the reference node, and the generated location information of the sensor node is transmitted to the cluster head (step 520). The generated position information of the sensor node is not fixed position information but relative position information.

Next, the cluster head receiving the position information from the sensor node generates the position information of the cluster head itself according to the position information of the sensor node (step 530).

The cluster head receiving the location information from the sensor node generates its own location information in the same manner as the sensor node. The cluster head receives all the location information of sensor nodes in the cluster. The cluster head itself generates location information based on the distance from the sensor node and the location information of the sensor node according to the transmission signal strength of the location information of the sensor node.

Next, the cluster head transmits the position information of the sensor node and the generated cluster head position information to the access node (S540).

The cluster head stores not only its generated location information but also the location information of sensor nodes included in the same cluster. Accordingly, the cluster head transmits not only its own location information but also the location information of the sensor node received by the cluster head to the access node.

The access node that receives the location information from the cluster head generates its own location information (step 550).

Similar to generating location information at the sensor node and the cluster head, the access node generates its own location information based on the location information of the cluster head transmitted from the cluster head.

This can be obtained by using a triangulation method, by combining the position information of the transmitted cluster head and the distance obtained from the distance measurement database.

That is, the cluster head broadcasts its location information to the access node. The location information broadcast from the cluster head includes a node ID, a node type, and three-dimensional location information. The 3D location information may be location information including latitude, altitude, and longitude. Stores the transmission signal strength of the cluster head having a signal strength equal to or greater than a predetermined threshold value among the transmission signals of the position information of the broadcast cluster head, and stores the access node and the cluster head according to a database according to the stored signal strength of the cluster head. Calculate the distance between and. The location information of the access node is generated according to the location information of the cluster head and the calculated distance from the cluster head.

Next, the access node constructs a location registration message by combining the location information of the access node itself, the location information of the sensor node, and the location information of the cluster head (step 560).

Table 3 shows position information storage tables of subordinate nodes existing in the cluster head and the access node. Referring to Table 3, the location information storage table consists of a sensor node identifier (ID), a sensor node type (type), three-dimensional location information including latitude, altitude, and longitude, a received signal strength (RSSI), and a distance, and is fixed. It has the size of the table. When the table is saturated or a predetermined time elapses, the cluster head constructs a location information transmission message and transmits it to the access node, and the access node constructs a location registration message and transmits it to the base station.

Table 4 shows sensor node types of the sensor nodes of Table 3. The sensor node type can be configured from 0x00 to 0xff, which can of course be changed depending on the actual implementation.

More specifically, the access node may comprise a dual mode mobile communication terminal. As described above, the dual mode mobile communication terminal generates its own location information, collects its own location information, location information of the sensor node and location information of the cluster head, and transmits the location information to the base station.

Table 5 is a configuration diagram of a location registration message in which a dual mode mobile communication terminal transmits location information to a base station. In addition to the fields included in the existing location registration message, sensors stored in the terminal's own location information and the location storage table of the sensor node It consists of the location information field of the node. The location information field of the sensor node is changed by the number of sensor nodes.

Table 6 is a location registration message used in a conventional IS-2000 mobile communication network, and there are various types of location registration methods in addition to location registration due to periodic location registration or parameter change. This is a location registration method used in a conventional mobile communication network and can be applied to the present invention by adding only a location information field to an existing location registration message.

Next, the location registration message is transmitted to the base station (step 570).

In the method of transmitting location information from an access node to a base station, the location information field may be added to an existing location registration message and transmitted. That is, a location information field for storing location information of the access node itself and location information of the sensor node is added to the existing location registration message field.

More specifically, the method for transmitting a location registration message may be triggered by a periodic method, a base station location change, a parameter change such as a system identifier or a network identifier, a mobile communication network or Or a method made by a base station request.

The time point for transmitting the location registration message to the base station may be configured to be a time point after the table for storing the location information is saturated or a predetermined time has elapsed.

On the other hand, when a large amount of location information of the sensor node is accumulated, the location information is aggregated or compressed. Alternatively, when it is practically impossible to aggregate or compress location information at one time and transmit it at once, a method of transmitting a plurality of times at a predetermined time interval is applied.

Next, the base station transmits a location registration message to the location information server through the mobile communication network (step 580).

The base station transmits the location information of the access node and the location information of the sensor node to the location information server through the mobile communication network. The location information server, which has received the location information, may maintain and manage the location information and use the location information in various application services.

Finally, when a data query request for the location information stored in the location information server is transmitted from any client including the access node, the location information stored in the location information server is provided to the desired requesting client (step 590).

On the other hand, the above description is an embodiment when the sensor nodes are hierarchically configured. However, the present invention is also applicable to a case in which a sensor node having a horizontal structure rather than a hierarchical structure is configured. In this case, the sensor node may receive the location information directly from the reference node instead of obtaining its location information only by the lower node, or may receive the location information from the neighboring node having the location information. The access node may also receive location information directly from a reference node or a sensor node that is close in distance.

In the hierarchical sensor network, a small number of reference nodes are required, and the load of the access node is less because the sensor node is aggregating or compressing the location information of the lower nodes step by step. In the sensor network in the horizontal structure, the sensor node or the dual mode mobile communication terminal can receive the position information from the reference node in a short time and receive the position information directly from the reference node, thereby obtaining precise position information. do.

6 is a detailed flowchart of a step 570 of transmitting a location registration message to an eNB by an access node.

First, the access node receives the location information from the cluster head (step 671) and stores the location information of the sensor node and the cluster head in the location information table (step 672). The location information table of the access node may use the location information table of the cluster head as it is. In the same way as the sensor node generates its own location information, the access node generates its own location information (step 673). It is determined whether the currently generated location information is different from the location information of the previously generated access node (step 674). If the currently generated location information is different from the location information of the previously generated access node, the currently generated access is performed. In step 675, a location registration message including location information of the node is transmitted to the base station. In this case, only the location information of the access node is transmitted to the base station without transmitting the location information of the sensor node.

On the other hand, if the current location information of the generated self and the location information of the previously generated access node is the same (waiting step 676), the location information of the access node and the location information of the sensor node in the location registration message In step 677, the location registration message including the message is transmitted to the base station. If the ACK message is received from the base station, the location registration is successful (step 678).

FIG. 7 is a detailed flowchart of a step 580 of transmitting a location registration message from a base station receiving the location registration message of FIG. 5 to a location information server.

Referring to FIG. 7, when the base station receives the location registration message from the access node (step 781), the base station examines the location registration message (step 782). If there is an error, the location registration message is discarded (step 783) and the location registration message is received again. If there is no error, the location registration is determined to be successful and an ACK message is transmitted to the access node (step 784). Finally, the base station transmits the location registration message to the location information server through the mobile communication network (step 785).

8 is a detailed flowchart of a step 590 of providing location information to an arbitrary client in the location information server of FIG. 5.

Referring to FIG. 8, when an arbitrary client requests location information of an access node, a cluster head, or a sensor node (step 891), the location information server that receives the location information request retrieves corresponding location information (step 892).

The location information server determines whether the location information is stored in the location information server (step 833), and if the requested location information is stored in the location information server, the location information server provides the location information to any requesting client (step 894).

If the requested location information is not stored in the location information server, the location of the requested sensor node, cluster head or access node in the sensor network network is tracked (895) to provide location information to any client requesting the location information. (894).

Referring to FIG. 9, at least three location information received from a node having location information, that is, three-dimensional location information X1, Y1, and Z1 from a location information node 910 having location information, and a location information node 920. 3D position information (X2, Y2, Z2) and position information node 930 from the three-dimensional position information is obtained. Then, the position information of the sensor node 940 is obtained according to the triangulation method of obtaining its own position information (x, y, z).

10 illustrates another embodiment of calculating position information of the present invention.

Referring to FIG. 10, when the location information nodes 1010, 1020, and 1030 transmit their location information to a higher node in order to measure distances more precisely from the location information node having location information, the location information nodes 1010, 1020, and 1030 transmit the full power from the beginning. Rather, increase transmission power step by step. By increasing the transmit power step by step in this way, the strength of the received signal when the transmitted message finally reaches the upper node is obtained. Based on the strength of the received signal, the distance measurement database is accessed to calculate distances distant from the location information nodes 1010, 1020, and 1030, that is, d1, d2, and d3. This is to more accurately calculate the d1, d2 and d3 described above in FIG. In this case, the location information nodes 1010, 1020, and 1030 transmit the same message a plurality of times until the sensor node 1040 finally receives it.

Although the present invention has been described with reference to the embodiments shown in the drawings, this is merely exemplary, and it will be understood by those skilled in the art that various modifications and equivalent other embodiments are possible. Therefore, the true technical protection scope of the present invention will be defined by the technical details of the appended claims.
