Description

A method and apparatus for providing information about energy usage through a femto network. {METHOD AND APPARATUS FOR PROVIDING INFORMATION TO ENERGY CONSUMPTION USING FEMTO NETWORK}

The present invention relates to a method and apparatus for providing information on energy usage through a femto network and controlling the amount of energy usage.

Generally, meter meter is used to generate meter reading data by quantifying the amount of supply energy which is difficult to calculate by manpower such as electricity, gas, water, hot water, calorie, etc. by using mechanical and electronic measurement means in the field. Various types have been developed and applied depending on the kind of energy to be used or the usage and scale of the metering meter.

The amount of the metering data measured through the metering meter has been calculated according to a manual detection system in which a person individually visits the local area where the metering meter is installed and confirms the amount of the metering data to the metering agency. When the meter reading data amount is counted through the manual detection system, the meter reading organization notifies each user of the calculated energy usage fee based on the counted meter reading data amount. The passive detection system operated as described above has a problem of high cost burden such as time and labor costs and inaccuracy due to being performed by a person.

In order to solve the problems of the passive detection system, an automatic detection system through a digital metering meter has been introduced. In the automatic detection system, the meter reading data measured through the digital metering meter is transmitted to a server of a meter reading institute located at a remote place through internet communication using a general telephone line or Internet exclusive line, or power line communication. Then, the measuring instrument converts the amount of the metering data of each of the local regions collected through the server into a usage fee, and issues a fee bill to the users of the corresponding local regions. The automatic detection system as described above is advantageous in that it enables quick and accurate grasping of the energy meter reading data in the measuring instrument at a lower cost.

However, until now, the user can still actively check the amount of energy used in advance, other than the passive method of receiving the bill and checking the corresponding amount of energy and paying the corresponding cost, It did not exist.

Therefore, there is a need for a concrete method for checking the energy consumption immediately from the viewpoint of the user and controlling the amount of energy consumption according to the amount of energy to be used.

The present invention provides a method and apparatus for providing energy consumption information and controlling energy usage accordingly.

The present invention provides a method and apparatus for providing information on energy usage of a local area through a femto base station.

The present invention provides a user with information on energy usage of a local area served by the FAP using a femto access point (hereinafter, referred to as 'FAP'), And a method and an apparatus for controlling the amount of energy used in the local region.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a diagram showing an overall configuration of a system for providing information on energy usage according to an embodiment of the present invention and controlling energy usage accordingly. FIG.

Referring to FIG. 1, the system includes an automatic detection system 100 for automatically accumulating and detecting energy usage of corresponding regions without detecting a detection attraction, an energy usage control system 110 for controlling energy usage in real time, .

The automatic detection system 100 includes a meter reading unit 102, a traffic concentrator 104 and smart meters 1,2 (106a, b), and the energy usage control system 110 is connected to the smart meter 1 2 106a and 106b and a gauge FAP 108 and a user terminal 110. The user terminal 110 includes a user terminal 110a and a user terminal 110b. The user terminal 110 is a terminal registered in the G-FAP 108. In FIG. 1, for example, only one user terminal 110 registered in the G-FAP 108 is described as an example However, it goes without saying that the present invention is also applicable to a case where there are a plurality of user terminals.

The automatic detection system 100 performs a general meter reading operation. Specifically, each of the smart meters 1, 2 (106a, b) measures the amount of energy used in a local area where the smart meters 1, 2 (106a, b) are installed as digital meters and transmits them to the traffic concentrator 104. [ The local area represents a small communication area such as an independent office, a residence, a building, and the like. The traffic concentrator 104 cumulatively stores the energy usage amounts from the smart meters 1 and 2 (106a, b), and transmits the accumulated energy usage amount from the provider at a preset time to the surveying institution 102 . The inspector 102 confirms the energy usage fee corresponding to the energy usage amount corresponding to the local area at the preset time and transmits the confirmed energy usage fee to the smart device 104 via the traffic concentrator 104. [ To the user of the local area where the meters 1, 2 (106a, b) are respectively installed.

In addition, the automatic detection system 100 may use an external device such as the Internet or the like by using a request from the user terminal 110 received through the G-FAP 108 or an application installed in the user terminal 110 in advance (106a, b) and the G-FAP (108) in accordance with an instruction of a user connected to the G-FAP (108) Then, the G-FAP 108 converts the energy usage of the corresponding area into the data format suitable for the user terminal 110 to transmit to the user terminal 110.

 Specifically, each of the smart meters 1 and 2 (106a, b) is connected to the G-FAP 108 using a wired / wireless data communication method such as Zigbee and Power Line communication (PLC). That is, each of the smart meters 1 and 2 (106a, b) in the automatic meter reading system 100 performs a general automatic meter reading operation for transmitting the energy usage amount to the meter reading organization 102 through the traffic concentrator 104 FAP 108 by transmitting the energy usage amount of the corresponding local area to the G-FAP 108 whenever the user terminal 110 makes a request or accesses the G-FAP 108 via the external means or the like, So that the energy consumption can be checked according to a preset condition. The smart meters 1 and 2 106a and 106b may receive the energy usage request message of the user terminal 110 transmitted through the G-FAP 108 or transmit the energy usage request message to the user terminal 110 or the external FAP 108. If the condition set in advance by the user connected to the G-FAP 108 is satisfied through the means such as the G-FAP 108, the cumulative energy usage amount of the corresponding local area is obtained from the traffic concentrator 104, . At this time, the condition that the energy usage is delivered to the G-FAP 108 includes 'when the energy accumulation amount of the corresponding local area exceeds a predetermined unit of the energy usage' or 'a certain time period'.

The G-FAP 108 receives a message directly requesting the energy usage from the user terminal 110 or receives the energy usage request from the smart meter 1 (1) according to a predetermined condition, , 2 (106a, b) to request the energy usage of the corresponding local area.

Then, the energy usage amount of the corresponding local area received from the smart meters 1 and 2 (106a, b) is converted into a data format for mobile communication through the G-FAP 108 and transmitted to the user terminal 110 .

For example, the data format for the mobile communication includes a Short Message Service (SMS) or a Multimedia Multicast Broadcast Service (MBMS) content . The form of the MBMS contents includes a text message, multimedia information in the form of a short moving picture, and voice information.

Meanwhile, the user terminal 110 receives SMS or MBMS content for mobile communication, which is generally received through a core network (CN), regardless of the current location. In addition, when the user terminal is located in a femtocell area serving as a service area of the G-FAP 108, the energy usage amount of the SMS or MBMS content type provided from the G-FAP 108 May also be received.

At this time, the user terminal 110 can easily grasp the energy usage amount of the local area managed by the user terminal 110 by displaying the received contents on the screen of the user terminal 110. [

A typical SMS or MBMS content is received from a CN by a macro base station or a general FAP and delivered to a user terminal. However, the G-FAP proposed in the present invention further includes a CN emulator for performing an operation for converting energy usage into data for mobile communication. That is, the energy usage [information] of the SMS or MBMS data type is transmitted from the CN emulator provided in the G-FAP 108 separately to the femto cell area served by the G-FAP 108, Can only be provided within. When the user terminals enter the femtocell area of the G-FAP 108, the user terminals camp on the G-FAP 108, so that the G-FAP 108 transmits the corresponding user It can be recognized that the terminals are located in the femtocell region of the terminal. That is, the G-FAP 108 recognizes that the user terminals maintaining the camp-on state are located in their femto cell area, and transmits the SMS or MBMS data to the camp-on state user terminals through the CN emulator It is possible to provide information on the energy consumption of the form.

2 is a schematic block diagram of a G-FAP according to an embodiment of the present invention. Here, it is assumed that the user terminal 210 is located in the femtocell region of the G-FAP 200, that is, the G-FAP 200 is camped on.

2, the G-FAP 200 includes an FAP block 205 that operates in a manner similar to a general FAP, a CN emulator block 210 that emulates the SMS server function of the CN, And a control unit 215. [0031] The control unit 215 controls the FAP block 205 and the CN emulator block 210.

Since the general FAP operation of the FAP block 205 is not related to the gist of the present invention, a detailed description thereof will be omitted here.

The control unit 215 is connected to a smart meter included in the automatic meter reading system by wired / wireless communication means such as Zigbee or PLC. The controller 215 receives the energy usage amount of the femtocell area where the user is located through the smart meters 1,2 (106a, b) in the automatic meter reading system 100 of FIG. 1 and transmits the energy usage amount to the user terminal 210 ) Into the format of a receivable SMS or MBMS content (format). Then, the CN emulator 210 converts the energy usage into the SMS or MBMS content format according to an instruction from the controller 215, and converts the energy usage of the femtocell area converted into the SMS message or the MBMS contents To the FAP block 205. The FAP block 205 transmits the information to the FAP block 205. [

Meanwhile, the controller 215 compares the energy usage with a threshold value of energy usage. The threshold is a value set by a user connected to the G-FAP 200 through a user terminal or an external means in order to adjust energy usage of the femtocell region. That is, the threshold may be preset in the G-FAP 200 by the user terminal 220 that has entered the femtocell region, or may be preset in the G-FAP 200 through external means such as the Internet, May be set prior to the user terminal 220 entering the femtocell region according to a command of a user connected to the femtocell 200. After the initialization of the G-FAP 200, the G-FAP 200, which has received the threshold setting message transmitted from the user terminal 220, The threshold value may be changed by an instruction received from the external means.

If the energy usage exceeds the threshold, the controller 215 transmits alarm information to the CN emulator 210 indicating that the energy usage of the femtocell area exceeds the threshold value, . Then, the CN emulator 210 converts the alarm information into SMS or MBMS content format according to the control of the controller 215, and transmits the converted SMS information to the FAP block 205.

Under the control of the controller 215, the FAP block 205 transmits information about an energy usage amount of the femtocell area converted to SMS or MBMS contents or an energy usage amount including an alarm message to the user To the terminal 220.

The control unit 215 transmits the alarm message to the CN emulator 210 as the energy usage exceeds the threshold value, and then controls the power of the household appliances in the femtocell area according to the priority inputted in advance Thereby controlling energy usage of the femtocell region. Specifically, the control unit 215 transmits a control signal for restricting energy usage to the corresponding home appliances, for example, by turning off the power of the home appliances in the femtocell region according to the priority inputted in advance. Then, the home appliances that receive the control signal shut off their power. In this case, it does not matter whether the user terminal 210 is located in the femtocell region. The pre-inputted priority is input through the user terminal 210 located in the femtocell region or connected to the G-FAP 215 through an external means such as the Internet linked to a predetermined application by a user And the like.

In addition, the control unit 215 receives a command message or command requesting control of energy usage of the femtocell region from the user terminal 210 or the external means located in the femtocell region, And controls the energy consumption of the femtocell region by controlling the power of the household appliances. At this time, the command message or command includes a procedure for power-off of the home appliances in the femtocell region, which is determined in consideration of the current state regardless of the priority inputted in advance. At this time, the current situation includes the order in which the current power usage is the highest or the order in which the necessity of maintaining the current power source is low. Upon receiving the command message or command, the control unit 215 transmits a control signal for restricting the amount of energy usage, such as shutting off the power according to the power-off sequence included in the command message, Lt; / RTI > Then, the home appliances that receive the control signal shut off their power.

In addition, the control unit 215 confirms the camp-on state of the user terminals registered in the G-FAP 200. As a result of checking, if all of the user terminals registered in the G-FAP 200 are out of the femtocell area, the controller 215 controls the home appliances To the power supply devices corresponding to the control signals for restricting the energy usage. Alternatively, the control unit 215 transmits control signals for limiting energy usage to corresponding power supply devices, such as shutting down the power of household appliances in the femtocell area. At this time, it is possible to separately set home appliances which should be excluded from the power-off by the user connected through the user terminal 210 located in the femtocell region or an external means such as the Internet linked to a preset application.

 The home appliances in the femtocell region are connected to each other using wired / wireless data communication means such as Zigbee or PLC with the G-FAP 200 so that signals transmitted from the control unit 215 of the G-FAP 200 The power of the home appliances can be turned on /

The FAP block 205 transmits information on the amount of energy usage, including energy usage and alarm information of the SMS or MBMS format, received from the CN emulator block 210 under the control of the controller 215, FAP 200 through a MAC (Media Access Controller) layer and a PHY layer (hereinafter, referred to as PHY layer) And transmits it wirelessly to the user terminal 220.

3 is a detailed configuration diagram of a G-FAP according to an embodiment of the present invention.

3, a femtocell region 300, a user terminal 305 located in the femtocell region 300, and a user terminal 305 for providing energy usage of the femtocell region 300 to the user terminal 305 G-FAP < / RTI > The femtocell region 300 is a local region that can be served by the G-FAP 310, and includes, for example, a store, a restaurant, and a theater.

The G-FAP 310 performs the same function as the FAP for providing general communication services to the user terminals located in the femtocell region 300 and additionally provides the FAP Block 307, a CN emulator block 315 for converting data related to energy usage of the femtocell area 300 received from the automatic meter-reading system into data for mobile communication, and a FAP block 307 And a controller 320 for controlling the operation of each of the CN emulator blocks 315.

The CN emulator block 315 controls the energy consumption of the femtocell region 300 based on the control of the controller 320 and the energy consumption including the alarm information indicating that the energy usage exceeds the threshold value And converts only the information into an MBMS content or an SMS message. Specifically, the CN emulator 315 includes an integrated block for emulating MBMS and SMS-related functions of the CN in order to convert only the information on energy usage of the femtocell area 300 into the MBMS or SMS content format, An SMS server block 317 and an SMS server block 319. The integration block 317 includes a Radio Network Controller (RNC), a Serving GPRS (General Packet Radio Service) Support Node (SGSN) (Hereinafter referred to as SGSN) and a mobile services switching center (MSC), respectively. That is, the SMS server block 319 receives the energy usage amount of the femtocell area 300 provided from the automatic meter reading system through the controller 320 or receives the energy usage amount of the femtocell area 300 from the controller 320 When the alarm information indicating that the energy usage exceeds the threshold value is received, the operation of the CN nodes for MBMS or SMS content generation is emulated and the energy usage of the femtocell zone 300, Converts the alarm information into a format of an MBMS or an SMS content, and transfers the converted alarm information to the FAP block 307. Since the RNC functional blocks and the SGSN and MSC functional blocks included in the integration block 317 are not directly related to the present invention, they can be implemented as a single block that simplifies the functions to which the corresponding protocol is applied, or a dummy block Block).

That is, the G-FAP 310 accesses the CN in the femtocell area served by the G-FAP 310 and provides a general mobile communication service to the user terminal 305. In addition, through the operation of the CN emulator 315, Information on energy usage of the femtocell region 300 may be additionally provided.

4 is a diagram illustrating a schematic protocol structure of a G-FAP according to an embodiment of the present invention.

Referring to FIG. 4, the protocol structure of the G-FAP 400 is the same as that of a general FAP. However, the G-femto base station further includes a protocol structure with the CN emulator block 404 that performs a function of converting energy usage of the femto base station and information related to the energy usage into an MBMS or SMS content type such as CN do. The CN emulator block 404 is connected to an automatic meter reading system.

The protocol structure of the G-FAP 400 includes an RNC function block 408 and a radio resource control (RRC) function 408 connected to the RNC function block 408 via U- A Radio Resource Control (RRC) block 410, a Packet Data Convergence Protocol (PDCP) block 412, a broadcast / multi A Radio Link Control (RLC) block 413 connected with the RRC block 410 through a Cyclic Radio Bearer (RLC) A MAC layer 417 connected to the RLC block 415 through logical channels and a PHY layer 419 connected to the MAC layer 417 through physical channels. . Here, the CN emulator block 404 is connected to the RRC 410. That is, the CN emulator block 404 converts the energy usage and the alarm, etc., obtained from the automatic meter reading system into an SMS message or an MBMSMBMS format, and transmits information on the energy usage amount to the control plane. This is because the control plane is connected to the RRC 410. The CN emulator block 404 delivers the MBMS or SMS content indicating the energy usage and the alarm to the RRC 410, The RRC 410 maps the MBMS or SMS content to an appropriate logical channel, and provides information on energy usage of MBMS or SMS content type to the corresponding user terminal.

5 is a flow chart of the operation of the G-FAP according to the embodiment of the present invention.

Referring to FIG. 5, in step 501, the G-FAP is powered on in a femtocell area in which it is located and proceeds to step 503. In step 503, the G-FAP is initialized and proceeds to step 505. [

In step 505, the G-FAP receives the energy usage amount of the femtocell area from the automatic meter reading system, and proceeds to step 507. In this case, when the G-FAP reaches a preset condition by the user connected through the user terminal or external means, or receives a request message or command through the user terminal or external means, Lt; / RTI > The above condition includes a case where the energy accumulation amount of the femtocell region exceeds a predetermined unit of energy usage, or a predetermined time period.

In step 507, the G-FAP compares the energy usage with a threshold value. The threshold value is a value set to control energy usage of the femtocell region. The threshold value is set before the G-FAP is powered on by a user terminal located in the femtocell region or a user connected through an external means. When a threshold setting command or a message is received by the user connected through the user terminal or the external means after initialization of the G-FAP, the G-FAP transmits the threshold setting command or the setting value included in the message The threshold value is changed.

If the energy usage is less than the threshold value, the G-FAP transmits information on an energy usage amount obtained by converting an energy usage amount into MBMS or SMS content type to the user terminal in step 506, And waits for the usage amount to be received.

If the energy usage exceeds the threshold value, the G-FAP transmits the alarm information indicating that the energy usage exceeds the threshold value to the user terminal in the MBMS or SMS content type An alarm message is transmitted and the flow proceeds to step 511. [ In this case, the energy usage is also converted into an MBMS or SMS content type like the alarm message, and is transmitted to the user terminal together with the alarm message. In step 511, the G-FAP controls energy usage of the femtocell region. Specifically, the G-FAP transmits a signal for shutting off the power of the home appliances according to a priority order preset by a user connected through a user terminal or external means among home appliances in the femtocell region, . The corresponding home appliances receiving the signal are turned off. In this case, the priority order is determined in the order that the power consumption of the power supply devices is large or the order in which the power supply is not required to be maintained at present.

In addition, the user terminal or the user who has received the alarm judges the home appliances or the like having the largest power consumption or the current power need not be turned on in consideration of the current situation by the user terminal or the external means, And transmits the command message to the G-FAP. The G-FAP receives the command message, and turns off the power of the home appliance indicated by the command message To the corresponding home appliances. Thereafter, the corresponding household appliances receiving the signal are turned off.

Through the above operation, when the user terminal is located in the femtocell region, the user terminal can check the energy usage amount of the femtocell region in real time, and the user terminal can confirm the energy usage of the femtocell region through the user terminal or external means, The energy consumption can be adjusted by performing a power-off operation of the household appliances located in the femtocell region by a user connected to the base station.
