4 through 8 are flowcharts illustrating operations of a digital wireless base station device and a home station device according to an embodiment of the present invention.

4 is a flowchart illustrating an operation of a home station apparatus according to a mesh network configuration command according to an embodiment of the present invention.

The home station device configures a mesh network using a FRS frequency for collecting and managing information of home station devices located nearby. When the mesh network is configured, when the first home station apparatus receives a mesh network configuration command from the base station or another home station apparatus (S110), the first home station may define network search pattern data previously defined at a FRS frequency. Transmit (S120).

At this time, the home station located near the first home station and receiving the search pattern data measures the reception strength of the search pattern data (for example, received signal strength indication (RSSI) strength and bit error rate (BER)) and measures the first pattern. Transfer to home station. Accordingly, the first home station receives RSSI strength and BER information from each neighboring home station (S140).

The first home station constructs a list of RSSI strengths and BER results for each ID (ID) of neighboring home stations based on the information received during the period until the timer expires (S150). The first home station selects a home station having excellent RSSI strength and BER result based on the configured list, and manages the best home station as a primary node and a second best neighboring home station as a secondary node (S160). For example, the ID information of the primary node and the secondary node is stored in the memory (S160), and the ID information of its own ID, the primary node and the secondary node is transmitted to the neighboring home stations (S170).

This mesh network configuration proceeds sequentially over all home stations so that all home stations belonging to the village announcement announcement broadcast can be linked.

Accordingly, the node map of the entire mesh network may be configured (S180).

FIG. 5 is a flowchart illustrating an operation in which a home station receiving a mesh network configuration command delivers its information and calls a neighbor home station to proceed with mesh network configuration.

For convenience of description, in the embodiment of FIG. 5, it is assumed that the operation of the second home station that receives the mesh network configuration command from another home station (eg, the first home station) is shown.

When the second home station receives the search pattern data from the surrounding first home station (YES in step S205), the second home station measures the received strength (RSSI strength) and the BER of the received search pattern data. (S210). If the second home station does not receive the search pattern data from the surrounding first home station, the second home station may operate in a specific mode (eg, a standby mode) or the procedure of FIG. 5 may end.

After measuring the reception strength and the BER of the search pattern data, it is checked whether the FRS channel is in the idle state (S215), and the ID, the reception strength, and the measured BER result are measured at the idle time in the first home. Transmit to the station (S220). If the FRS channel is in use in step S215, it may wait until the FRS channel becomes idle.

In addition, the second home station transmits network search pattern data at the FRS frequency (S225). At this time, the home station located around the second home station and receiving the search pattern data measures the RSSI strength and the BER of the search pattern data and transmits it to the second home station. Accordingly, like the first home station, the second home station also receives RSSI strength and BER information from each of the neighboring home stations (S240).

The second home station constructs a list of RSSI strengths and BER results for each ID of the home stations located in the vicinity based on the information received during the period until the timer expires (S250). The second home station selects a home station having excellent RSSI strength and BER result based on the configured list, and manages the best home station as a primary node and a second best neighboring home station as a secondary node (S260). For example, the ID information of the primary node and the secondary node is stored in the memory (S260), and the ID information of its own ID, the primary node and the secondary node is transmitted to the neighboring home stations (S270).

In this way, the mesh network configuration proceeds sequentially over the entire home station so that all home stations belonging to the village announcement announcement broadcast can be linked. Accordingly, the node map of the entire mesh network may be configured (S280).

As described above, as the node map of the entire mesh network is configured, each home station may manage information of its own primary node and secondary node. Accordingly, each home station may monitor the operation of the registered primary node and the secondary node (eg, whether to respond to a query signal, whether to receive a broadcast, and whether to transmit an emergency signal). If, at any home station, the operation of the primary or secondary node is not detected or is determined to be abnormal, the information of the abnormal operation node is transmitted to the base station to check the device of the node (ie, the corresponding home station device). You can do that.

FIG. 6 illustrates a process of delivering a broadcast reception information to a neighboring home station in a village announcement guide system shown in FIG. It is a figure which shows schematically.

1 and 6, the base station apparatus 100 broadcasts a village announcement announcement through a local radio frequency channel (1), and the first home station apparatus 200-1 is the base station apparatus 100. Receives and stores the village announcement guide broadcasted through the local radio frequency channel, that is, the channel selected by the base station device. In addition, the first home station apparatus outputs the received village announcement guide broadcast as a voice signal through a speaker.

The first home station apparatus 200-1 inquires whether the village announcement announcement broadcast data has been received by the second home station apparatus 200-2 (②). For example, the first home station device 200-1 generates a predefined query signal and transmits the generated query signal to the second home station device 200-2 using the FRS frequency band. (②).

The query signal may be a digital signal that is predefined in order to query the adjacent home station apparatus whether to receive a broadcast.

When the second home station apparatus 200-2 receives the query signal of the first home station apparatus 200-1, in response to the signal, the second home station apparatus 200-2 transmits its own broadcast reception state (that is, whether or not the broadcast reception is received) to the first home. Respond to the station apparatus 200-1 (3).

The broadcast reception state may include a normal reception state or an unreceived state. The normal reception state may include a broadcast direct reception state or a broadcast reception state through FRS communication.

For example, if the second home station apparatus 200-2 normally receives the village announcement information broadcast data from the base station apparatus, transmits a query response signal indicating the normal reception state to the first home station apparatus 200-1. If the second home station apparatus 200-2 does not normally receive the village announcement information broadcast data from the base station apparatus 100, transmits a query response signal indicating the unreceived state to the first home station apparatus 200-1. do.

The query response signal includes a caller (second home station device) identification information (ID), a destination (first home station device) identification information, a broadcast identification number, and a broadcast reception state (normal reception state or non-reception state) of the second home station device. It may include.

The first home station apparatus 200-1 converts the stored village announcement information broadcast data into a signal of the FRS frequency band based on the query response signal from the second home station apparatus 200-2, and thus the second home station apparatus 200-1. Forward to station apparatus 200-2 (④).

For example, when the query response signal from the second home station apparatus 200-2 indicates that the signal has not been received, the first home station apparatus 200-1 transmits the village announcement information broadcast data using a signal of the FRS frequency band. 2 is transmitted to the home station device 200-2 (④).

When the query response signal from the second home station apparatus 200-2 indicates that it is a "normal reception state", the first home station apparatus 200-1 transmits the base station apparatus 100 to the second home station apparatus 200-. The reception status of 2) (e.g., "normal reception status") (5).

For example, the first home station apparatus 200-1 may report a reception state (eg, a “normal reception state”) of the second home station apparatus 200-2 as a signal of the FRS frequency band, or receive a broadcast. A list of neighboring home station devices may be prepared and reported to the base station device 100.

According to an embodiment, the first home station apparatus 200-1 may directly transmit a reception completion message of the second home station apparatus 200-2 to the base station 100, or transmit at least one other home station apparatus. It can also be transmitted.

The second home station apparatus 200-2 receives a query signal from the first home station apparatus 200-1, and in response thereto, receives a query response signal that responds to a broadcast reception state of the corresponding announcement. Similar to the transmission to the home station apparatus 200-1, the other home station apparatus receives the query signal from the second home station apparatus 200-2, and in response thereto, reports its broadcast reception status for the corresponding announcement. The response query response signal may be transmitted to the second home station apparatus 200-2.

In this way, each home station device first checks whether a home station device of a neighboring home receives a guide broadcast using its digital living wireless station, and delivers the announcement to a neighboring home station device that has not received the guide broadcast. In other words, it is possible to reduce the shaded areas that do not receive announcements in the village.

The base station 100 may determine whether all home station devices in the village normally receive announcement announcements by receiving reception completion messages from the home station devices. In addition, the base station may identify a home station apparatus that does not normally receive the announcement broadcast in the village.

7A and 7B are flowcharts illustrating operations of the first and second home stations during base station broadcast reception according to an embodiment of the present invention.

First, referring to FIG. 7A, when the first home station apparatus receives a guide broadcast (BS broadcast) from the base station (YES in S310), the first home station apparatus outputs the guide broadcast through a speaker and stores the received broadcast content. (S320). The first home station apparatus queries the neighboring (or neighbor) home station for the broadcast reception at the FRS frequency (S330). The first home station apparatus may receive a response signal from the neighboring home station, and may determine whether the neighboring home station directly receives the BS broadcast signal through the response signal (S340).

As a result of confirming the response signal, if the neighboring home stations directly receive the BS broadcast signal (YES in S340), the broadcast reception home station list may be prepared and the reception lists may be transmitted at the FRS frequency (S350 and S370). The broadcast receiving home station list may include information (node ID, etc.) about the neighboring home station which directly receives the BS broadcast signal.

If, as a result of confirming the response signal, the neighboring home station does not directly receive the BS broadcast signal (if NO in S340), the BS broadcast content is transmitted to the neighbor HS at the FRS frequency (S360).

Referring to FIG. 7B, when receiving the BS broadcast through the FRS frequency (if YES in S410), the second home station apparatus outputs a guide broadcast through a speaker and stores the received broadcast content (S420). . The second home station apparatus queries the neighboring (or neighbor) home station for the broadcast reception at the FRS frequency (S430). The second home station apparatus may receive a response signal from the neighboring home station, and may determine whether the neighboring home station receives the BS broadcast signal through FRS group communication through the response signal (S440). If the neighboring home stations have received the BS broadcast signal through FRS group communication ('YES' in S440), the broadcast reception home station list may be created and the reception lists may be transmitted at the FRS frequency (S450, S470). . The broadcast receiving home station list may include information (node ID, etc.) about neighboring home stations that have received the BS broadcast signal at the FRS frequency.

If the response signal check result, if the neighboring home station did not receive the BS broadcast signal at the FRS frequency ('NO' in S440), the BS broadcast content is transmitted to the neighbor HS at the FRS frequency (S460).

According to an embodiment, each of the first and second home station apparatuses may check whether it has received a response signal to the query signal from its primary node and the secondary node to monitor whether the primary node and the secondary node are normally operating. Can be.

As described above, when the base station broadcasts an announcement broadcast (BS broadcast), the BS broadcast is transmitted from the home station that directly receives the BS broadcast to the home station that has not received the BS broadcast through FRS communication, and furthermore, the FRS communication. The BS broadcast may be transmitted from the home station receiving the BS broadcast to another home station through FRS communication. In addition, the list of the home station directly receiving the BS broadcast and the home station list received through the FRS communication may be divided and reported to the base station. Accordingly, the base station is a home to which the BS can directly receive the BS broadcast. Stations and home stations received through FRS communication may be classified and managed.

8 is a flowchart illustrating an operation of a home station apparatus for transmitting an emergency signal according to an embodiment of the present invention.

According to an embodiment of the present invention, when the home station receives the emergency code ('YES' in S510), the home station transmits the ID of the originating home station, the date and time of occurrence, the emergency code, and the emergency. The path of the home station is checked and the information is transmitted to the neighboring home stations (S520). In this case, in order to prevent multiple home stations from transmitting the same emergency incident to occupy the frequency of the living radio station, if the same incident is received as the first received and transmitted, it is managed not to be duplicated. For example, the home station compares the transmission ID (the ID of the original originating home station) and the occurrence date and time to check whether the reception is duplicated (S530). And transmit ID (S540).

9 shows examples of a home station receiving a BS broadcast according to an embodiment of the present invention. In FIG. 9, A_BS denotes a broadcast enable area of the BS, and A1, A2, A3, A4, and A5 denote FRS communication areas of the first, second, third, fourth, and fifth home stations HS1 to HS5, respectively. It is assumed to mean.

Accordingly, the first, second, and third HSs located in the broadcastable area A_BS of the BS may directly receive the BS village announcement announcement.

On the other hand, when the third HS queries the neighboring HS whether or not the BS broadcast is received, it receives an unreceived report from the fourth HS (HS4) and, accordingly, transmits the BS broadcast content to the FRS group communication.

The fourth HS (HS4) receiving the BS broadcast content through the FRS group communication may query the neighbor HS about whether the BS broadcast is received, and may receive an unreceived report from the fifth HS (HS5). Accordingly, the fourth HS (HS4) transmits the BS broadcast content to the FRS group communication, so that the fifth HS (HS5) can receive the BS broadcast from the fourth HS (HS4).

Accordingly, the fourth and fifth HSs located outside the broadcastable area A_BS of the BS may receive the BS broadcast through FRS communication.

In the emergency call, the emergency code is transmitted to the neighboring HS and the emergency code and the call ID are transferred to the neighboring HS in group communication from the received HS, so that the emergency code and the call ID can be transmitted to the BS.
