For example, the specific shapes, structures, and characteristics described herein may be implemented by changing from one embodiment to another without departing from the spirit and scope of the invention. It should also be understood that the location or arrangement of individual components within each embodiment may be varied without departing from the spirit and scope of the present invention. Therefore, the following detailed description is not to be taken in a limiting sense, and the scope of the present invention should be construed as encompassing the scope of the appended claims and all equivalents thereof. In the drawings, like reference numbers designate the same or similar components throughout the several views.

Hereinafter, various embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art can easily carry out the present invention.

Hereinafter, in the embodiment of the present invention, a network system in an aircraft is assumed for the sake of convenience of explanation, but a method of providing a user convenience service based on a network and an apparatus performing the method may be implemented not only in an aircraft but also in other transportation means And may be widely implemented to provide a user-friendly service based on a network in a fixed space or an independent space.

1, a user-friendly service system for providing a user-friendly service (for example, an in-flight entertainment service, an in-cabin commodity order service, a cabin call service, etc.) to a user located in a specific space (for example, .

Referring to FIG. 1, a user-friendly service system may include a management server 100, a service server 120, a relay device 140, and a user device 160.

The management server 100 may be implemented for management of the service server 120. The management server 100 may be implemented to manage / control the operation of the service server 120 that transmits data for a user convenience service to the relay device 140.

The service server 120 may be implemented for managing / providing data for providing a user convenience service (e.g., an entertainment service) to the user device 160. [ For example, the service server 120 may be located outside the aircraft, and the service server 120 may transmit data for a user convenience service to the relay device. The data stored in the relay apparatus 140 may need to be periodically updated and the service server 120 may provide the update service for the data to the relay apparatus 140. [

For example, the relay device 140 may be collected after the landing of the aircraft, form a network with the service server 120, and proceed with the update procedure for the data. The service server 120 can perform data transmission using a plurality of transmission methods using a plurality of relay devices 140. A method of transmitting data to the plurality of relay apparatuses 140 of the service server 120 will be described later in detail.

The relay device 140 is located inside the space (e.g., an aircraft) and is implemented to transmit data for user-friendly service to the user device 160 of a user located in the space (or a user aboard the aircraft) . The relay device 140 receives the user's request (for example, a content request, an article purchase request, a crew call request, etc.) through communication with the user device 160, and transmits data according to the user's request to the user device 160 ).

The repeater 140 located in the cabin can be collected for charging and / or content update, and can be connected to a docking device that docks the repeater 140. The relay device 140 connected to the docking device may operate in a charge mode and / or an update mode. The charging mode may be a mode for charging the battery of the relay device 140 and the update mode may be a mode for updating the content data of the relay device 140. The docking device supplies power for charging to the relay device 140 through a connection to an external power source and supports a network connection such as Ethernet to establish a communication network between the relay device 140 and the service server 120 .

At least one relay device 140 may be located inside the aircraft, and at least one relay device 140 may be assigned a different role (master relay device, slave relay device, etc.) Can be performed. The operation according to the role of the relay device 140 will be described later in detail.

The user device 160 may be implemented to provide a user-friendly service directly to the user based on the data received from the relay device 140. For example, the user device 160 may be a device carried by a user such as a smartphone, a smart pad, or a notebook of a user who has boarded the aircraft. A network is established between the user device 160 and the relay device 140 after the user boarding the aircraft and a user convenience service is provided to the user device 160 through communication between the relay device 140 and the user device 160 .

In Fig. 2, a method for a service server to transmit data to a relay apparatus is disclosed. As described above, data transmission from the service server to the relay device may be required for the service of the relay device to the user device. Periodic updating of data stored in the relay apparatus is required, and periodic data updating of the relay apparatus can be performed by the service server.

Referring to FIG. 2, at least one relay device 220 may be connected to the service server 200 to configure a network. A network between the relay apparatuses 220 can also be configured. For example, the relay device 220 collected in the aircraft is docked to a base dock 240 for configuring a network between the service server 200 and the relay device 220, Can be formed.

The service server 200 may transmit the data to the relay device 220 through the formed network to perform the update procedure. In addition, the relay device 220 may transmit the generated log data to the service server 200 when the convenience service is provided to the user in the aircraft. The log data may include information such as a user service request record generated while providing a user convenience service to the user device. The log data transmitted by each of the plurality of relay apparatuses 220 may be inquired and confirmed by the service server 200.

The method of transmitting data to the relay apparatus 220 of the service server 200 may include a direct transmission method, an entire transmission method, and a distributed transmission method.

The direct transmission method can be used for data transmission between one relay device 220 and one service server 200. For example, in the direct transmission method, a data update request message generated by the relay apparatus 220 may be transmitted to the service server 200. The service server 200 receiving the data update request message can transmit data for updating to the relay device 220. That is, in the direct transmission method, one relay device 220 and one service server 200 are connected and data can be transmitted based on a unicast transmission.

The entire transmission method can be used for data transmission between a plurality of relay apparatuses 220 and one service server 200. Confirmation of the version data of each of the plurality of relay apparatuses 220 may be performed before data transmission based on the total transmission method. The relay apparatus 220 may have version information for identifying information on the data currently held.

The service server 200 can confirm the information about the data stored in the relay device 220 based on the version information and check whether the update of the data is necessary based on the version information and then transmit the updated data to the relay device 220).

The transmission of data to the relay apparatus 220 that requires updating may be performed on a broadcast basis.

A problem may occur in reception of data transmitted on a broadcast basis. In this case, after completion of the broadcast-based data transmission of the service server 200, the service server 200 may separately transmit data on the unicast basis to the relay apparatus 220 in which the reception problem occurs.

In the distributed transmission method, data can be transmitted through the communication between the relay devices 220. Transmission from the relay apparatus (hereinafter referred to as the data reception complete relay apparatus) that has completed the reception of the data to the relay apparatus (the data reception incomplete relay apparatus) that has not completed the reception of the data can be performed. The load of the service server 200 can be reduced based on the distributed transmission method.

For example, the data reception incomplete relay apparatus can request transmission of data to the service server 200, and the service server 200 can transmit information on the data reception completion relay apparatus to the data reception incomplete relay apparatus. The data reception incomplete relay apparatus can set up the data reception completion relay apparatus and the network based on the information on the data reception completion relay apparatus and can receive the data from the data reception completion relay apparatus.

In Fig. 3, the role of a relay device in a network environment in a specific space (e.g., an aircraft) is specifically disclosed.

Referring to FIG. 3, the relay apparatus may serve as the master relay apparatus 300 or the slave relay apparatus 320 under the network environment in the aircraft.

The master relay device 300 may exist on at least one (e.g., one) aircraft network implemented within an aircraft. The slave relay apparatus 320 can duplicate and use the database of the master relay apparatus 300. [ When the slave relay apparatus 320 receives a command for requesting a write to the database from the user apparatus, the slave relay apparatus 320 can transmit the write request to the master relay apparatus 300 without directly processing the command.

The slave relay apparatus 320 may include a synchronous slave relay apparatus 340 and an asynchronous slave relay apparatus 360.

The synchronous slave relay apparatus 340 may synchronize, duplicate and store the database of the master relay apparatus 300. The synchronous slave repeater 340 may exist on at least one (e.g., one) aircraft network implemented within an aircraft. The synchronous slave repeater 340 can operate by changing the role of the master relay apparatus 300 when the master relay apparatus is disappeared on the intra-cabinetwork. When the synchronous slave relay apparatus 340 is changed to the master relay apparatus 300, one of the asynchronous slave relay apparatus 360 described later can change its role to the synchronous slave relay apparatus 340.

The asynchronous slave repeater 360 may perform an asynchronous copy of the database of the master relay apparatus 300 and process a request. The asynchronous slave repeater device 360 may not be present on the intra-aircraft network implemented in one aircraft, and may exist at least one (for example, one), if any.

The assignment to the relay device (master relay device 300, synchronous slave relay device 340, asynchronous slave relay device 360) can be performed based on information on signals on the network.

If a plurality of repeaters are located in the aircraft, a measurement of the signal strength between the repeaters can be performed. Information on the radio signal strength between relay apparatuses is obtained through the signal strength measurement process and a weighted network graph can be formed based on information on the radio signal strength between relay apparatuses. The weighted network graph may include information on the radio signal strength or a predicted distance between repeaters.

As a result of the determination based on the weighted network graph, the relay apparatus determined to have the smallest average of the predicted distances from other apparatuses may be determined as the master relay apparatus 300, and the remaining relay apparatuses may be determined as the slave relay apparatus 320 have.

That is, the master relay apparatus 300 is a relay apparatus having a shortest predicted distance from other relay apparatuses determined based on information on radio signal strength among a plurality of relay apparatuses located in an independent space (for example, an airplane) The relay device 320 may be a relay device other than the master relay device 300 among a plurality of relay devices located in an independent space (for example, an airplane).

A slave relay apparatus having the largest signal strength on the network of the master relay apparatus 300 among the slave relay apparatus 320 can be determined as the synchronous slave relay apparatus 340. [ And the remaining slave relay apparatuses may be determined as the asynchronous slave relay apparatus 360. [

The master relay apparatus 300 and the slave relay apparatus 320 can perform the same service provision.

For example, the master relay apparatus 300 and the slave relay apparatus 320 can provide a user-friendly service (for example, an entertainment content providing service) based on the same data, and the master relay apparatus 300 and the slave Each of the relay apparatuses 320 can individually provide the user-friendly service through the user apparatus of the user in the aircraft without communication between the relay apparatuses.

The master relay apparatus 300 and the slave relay apparatus 320 can operate in different ways when a request for a function requiring synchronization is generated by the user.

Operations of the master relay device 300 and the slave relay device 320 are specifically described below.

If the slave relay apparatus 320 receives a request from the user apparatus for writing in the database, the master relay apparatus 300 receives the database write request from the slave relay apparatus and processes the database write request You can respond.

Synchronization is required for the databases of the master relay device 300 and the synchronous slave relay device 320 for the database write request. The following processing procedure may be performed to synchronize the databases of the master relay apparatus 300 and the synchronous slave relay apparatus 340. [

A request for writing based on an API (application programming interface) (hereinafter referred to as a writing API) for writing operation from the user device may be generated. All relay devices can receive a write request based on the write API irrespective of whether the role of the device connected to the current user device is the master relay device 300 or the slave relay device 320. [

If the relay device receiving the write request is not the master relay device 300 but the slave relay device 320, the write request may be transmitted to the master relay device 300. The master relay apparatus 300 can process the received write request and apply the result of the write request to the database. The master relay device 300 may transmit the database synchronization request for the changed contents due to the write request to the synchronous slave relay device 340 after processing the write request transmitted to the database.

If the database synchronization is successful, the synchronous slave repeater 340 may send a database synchronization success response to the master relay device 300. Further, the result of the change of the database of the master relay apparatus 300 can be transmitted to the asynchronous slave relay apparatus 360. [ The result transfer process for the change of the database to the asynchronous slave repeater 360 may be performed asynchronously and therefore may not block the execution of the subsequent process. The master relay device 300 may return a result value (success) for the database write request.

That is, when there is a change in the database of the master relay apparatus, the database of the synchronous slave relay apparatus reflects the change contents on the basis of synchronization, and the database of the asynchronous slave relay apparatus reflects the change contents on the asynchronous basis.

Conversely, if the database synchronization fails, the synchronous slave relay device 340 may send a database synchronization failure response to the master relay device 300. In this case, the changed contents of the database of the master relay apparatus 300 may be rolled back to the state before the change. If the database synchronization is unsuccessful, the master relay device 300 may return information informing the write request failure to the user device. The master relay device 300 may return the result information for the write request and the result information for the write request may be transmitted to the user device that transmitted the write request.

Even if the database is synchronized, the log of each relay device may not be synchronized. The log of each relay device can be recorded / managed by the independent database of each relay device.

A write request can be raised for requests such as CREATE, UPDATE, DELETE, and so on in the database. For example, a write request by the user device to an operation requiring data input such as a new order request, order change, order cancellation, order processing state change, service state change, travel information change, .

A request that does not require writing to the database (hereinafter, a write-unnecessary request) can be performed with reference to the database of each relay device. For example, a write-free request may be a read request from the database. For example, a read request by a user device may be generated in the relay device for operations such as product inquiry, video, music appreciation, order inquiry, travel information confirmation, crew call result confirmation, and the like.

Referring to FIG. 4, the slave relays 410 and 420 need to continuously communicate with the master relay apparatus 430 for write request processing, database synchronization, and the like.

The signal strength is very weak due to the physical distance between the master relay device 430 and the

slave relay devices

410 and 420 in the communication between the master relay device 430 and the

slave relay devices

410 and 420, Lt; / RTI >

In this case, the

slave repeaters

410 and 420 find the shortest path for communicating with the master relay device 430 based on the weighted network graph generated when determining the role of the relay device described above, And transmits it to the relay device 430.

For example, it may be difficult for the slave repeater 1 410 and the master repeater 430 to communicate directly with each other. At this time, the shortest network path can be determined with reference to the weighted network graph configured based on the radio received signal strength. When the second slave relay apparatus 420 exists on the shortest network path, the first slave relay apparatus 410 can communicate with the master relay apparatus 430 through the second slave relay apparatus 420. The slave relay apparatus 2 420 can transmit data on the network.

Various criteria can be applied to determine the slave repeater on this intermediate path. For example, a slave relay device for transferring data may be determined in consideration of the state of the battery of the slave relay device located in the middle, the number of the user devices serviced by the slave relay device located in the middle, and the like.

5, a procedure for exchanging information on a weighted network graph between relay apparatuses is disclosed.

Referring to FIG. 5, the weighted network graph 500 may include information on the strength of a wireless signal generated on a network connection between relay apparatuses used in an airline.

As described above, the weighted network graph 500 can be used to check the communication status between repeaters in the aircraft and to set the role of the repeater.

The weighted network graph 500 may be generated during a communication status check (or heartbeat check) process for the relay apparatus. This communication status checking procedure may be performed non-periodically or periodically (e.g., once per minute).

All relay apparatuses can periodically check the status of other relay apparatuses in the vicinity, and can quickly identify and respond to which relay apparatus has failed. Such state determination between the relay apparatuses may be a communication state check (or a heartbeat check).

The communication status check can be performed based on 1) searching for the neighboring relay apparatus, and 2) exchanging the weighted network graph between the relay apparatuses.

The relay apparatus searches for a nearby wireless network signal and searches for a wireless communication apparatus (for example, an access point (AP)) having specific identification information (e.g., SSID (service set identifier) Can be found. All the wireless communication devices found through this operation are regarded as peripheral relay devices, and a weighted network graph between the relay device and the peripheral relay device can be set based on the radio signal strength and MAC (medium access control) address of each of the peripheral relay devices have.

The relay device may determine information on the communication state by merging information on the existing weighted network graph 500 of the neighboring relay device and information on the new weighted network graph 500 of the neighboring relay device.

For example, if there is information on the existing weighted network graph 500 for the neighboring relay device, the newly generated weighted network graph 500 for the existing weighted network graph 500 and the neighboring relay device is merged . If the neighboring relay apparatus corresponding to the existing weighted network graph information is later disappeared at the time of searching for the peripheral apparatus, the information related to the missing browsable relay apparatus and the search disable relay apparatus can be deleted.

The relay device may exchange information about the weighted network graph 500 with the neighboring relay device. For example, the relay device may send information about the weighted network graph 500 directly generated to the neighboring relay device or receive information about the weighted network graph 500 generated by the neighboring relay device from the neighboring relay device have. The relay device may determine the communication state between the relay device and the peripheral relay device by merging the weighted network graph 500 directly generated and the weighted network graph 500 received from the peripheral relay device.

The relay apparatus can perform the deletion procedure on the information on the unavailable relay apparatus included in the information on the weighted network graph 500 received from the peripheral relay apparatus but not directly searchable.

6, a merging procedure of a weighted network graph between relay apparatuses is disclosed.

The weighted network graph may include information on a predicted distance value between each relay apparatus. For example, the stronger the signal between the relay apparatuses, the smaller the predicted distance value between the relay apparatuses can be, and the intensity of the signal between the relay apparatuses (or the communication state between the relay apparatuses) can be estimated based on the predicted distance value.

Referring to FIG. 6, the weighted network graph may be merged with another weighted network graph.

When merging between weighted network graphs is performed, merging between weighted network graphs can be performed on all relay devices (or nodes) present in the weighted network.

When merging is performed for all relay devices (or nodes), the predicted distance between relay devices can be determined based on an average value of a plurality of predicted distances present on the weighted network graph.

The weighted network graph 1 610 may include communication status information for the relay apparatus B, the relay apparatus C, and the relay apparatus D based on the relay apparatus A. [

The weighted network graph 2 (620) may include the communication status information for the relay apparatus A, the relay apparatus C, and the relay apparatus E based on the relay apparatus B. [

It can be assumed that the merging of the weighted network graph 1 (610) and the weighted network graph 2 (620) is performed based on the relay apparatus A.

The weighted network graph 3 (630) is a graph generated by merging the weighted network graph 1 (610) of the relay apparatus A and the weighted network graph 2 (620) of the relay apparatus B.

Referring to the weighted network graph 3 (630), it can be confirmed that the predicted distance value between the relay apparatus B and the relay apparatus C is an average value. In this way, the weighted network graph is merged to more accurately predict the distance between the relay apparatuses, and the role of the relay apparatus can be determined according to the distance between the relay apparatuses.

A correction for the predicted distance value can be performed for the accuracy of the predicted distance value between the relay apparatuses. For example, the predicted distance value may exceed the set spatial range. When the relay device is installed in the aircraft, the predicted distance to the outside based on the size of the aircraft may be measured at a distance or more. In this case, the predicted distance may be reduced in consideration of the size of the aircraft, or the predicted distance value may be ignored.

Also, a plurality of predicted distance values may be measured on the weighted network graph, and a predicted distance value may be determined based on the plurality of predicted distance values. However, only one predicted distance value may exist between relay apparatuses. In this case, an additional measurement may be performed to obtain a second predicted distance value, and a predicted distance value between relay apparatuses may be determined based on the first predicted distance value and the second predicted distance value.

In Fig. 7, when the master relay apparatus is lost on the network, the processing procedure is started.

Referring to FIG. 7, if the master relay apparatus 700 is lost on the intra-aircraft network or does not respond to the long-term request, an alternative procedure for the master relay apparatus 700 may be performed.

An update to the weighted network graph may be performed through the communication status confirmation procedure for the relay apparatuses for the replacement procedure for the master relay apparatus 700. [

After confirming the communication status, at least one of the synchronous slave repeaters 740 may be changed to a master relay apparatus.

Also, at least one of the asynchronous slave repeaters 760 can be changed to a synchronous slave repeater.

Similarly, if the synchronous slave repeater 740 is lost on the intra-aircraft network or does not respond to the long-term request, an alternative procedure to the synchronous slave repeater 740 may be performed.

An update to the weighted network graph may be performed through the communication status check procedure for the relay apparatuses for the replacement procedure for the synchronous slave relay apparatus 740. [

After confirming the communication status, the asynchronous slave repeater 760 can be changed to serve as the synchronous slave repeater at least one relay device.

In addition, according to the embodiment of the present invention, when a relay apparatus is newly added, it can be allocated as an asynchronous slave relay apparatus irrespective of the role set in the relay apparatus.

8 is a conceptual diagram illustrating a method for assigning a user apparatus to a relay apparatus on a network according to an embodiment of the present invention.

Figure 8 discloses a method for assigning a plurality of user equipments to each of a plurality of relay apparatuses when a plurality of relay apparatuses provide user-friendly service to a user apparatus in an independent space (for example, an aircraft).

When the provision of the user-friendly service to a relatively large number of user equipments is performed through a single relay device, the burden on the relay device can be increased. Thus, when user convenience service to a relatively large number of user devices is provided through one relay device, the master relay device can control the allocation of communication resources.

8, the user equipments 1 to 6 are provided with user convenience service through the relay device 1 810, and the user device 7 and the user device 8 provide user convenience service through the relay device 2 820 Can receive.

Each of the

relay apparatuses

810 and 820 is connected to the master relay apparatus 800 through information about a user apparatus currently serving (hereinafter, referred to as a service target user apparatus) and a serviceable user apparatus (Hereinafter referred to as " user equipment information "). Although the

relay apparatuses

810 and 820 do not currently provide the user-friendly service, they can determine the serviceable user apparatus existing in the coverage available for communication as a serviceable user apparatus.

For example, the user device information may include at least one of an identifier of a user device, a number of user devices, an intensity of a signal transmitted by the user device, and information on a user convenience service provided to the user device.

The user device information may separately include information on the service target user device and information on the serviceable user device.

The information about the service target user device may include an identifier of the service target user device, a number of service target user devices, a strength of a signal transmitted by the service target user device, and information about the user convenience service provided to the service target user device have. The information about the serviceable user equipment may include an identifier of the serviceable user equipment, information about the strength of the signal transmitted by the serviceable user equipment.

The master relay apparatus 800 can receive the user apparatus information and adjust the load for each relay apparatus. The master relay apparatus 800 can determine the position of the user apparatus closest to the relay apparatus 2 820 among the user apparatuses 1 to 6.

For example, the master relay apparatus 800 judges that the user apparatuses 4 to 6 are included in the communication coverage of the second relay apparatus 820 based on the user apparatus information transmitted by the relay apparatus 2 (820) can do. In this case, it is possible to change the relay device assignment of the user equipment from the relay device 1 810 to the relay device 2 820 in the order close to the relay device 2 820 in the user devices 4 to 6. The distance between the user equipment and the relay apparatus 2 (820) may be determined based on the strength of the signal transmitted by the user equipment included in the user equipment information.

At this time, if the user apparatus 4, the user apparatus 5, and the user apparatus 6 are close to the relay apparatus 2 (820), the relay apparatus assigned to the user apparatus in the order of the user apparatus 4, the user apparatus 5, 810 to the relay apparatus 2 (820).

Or additionally, the user equipment to newly allocate the relay apparatus can be determined by further considering the data transmission prediction amount for the user convenience service. The amount of data for the user-friendly service may be different. For example, if the user convenience service is a video content providing service, the amount of data for the user convenience service is relatively large, and if the user convenience service is an order service for goods or a call for a flight attendant, Can be relatively small. Therefore, the amount of data for the user-friendly service provided by one relay device is predicted, and the user device can be allocated to the relay device so that the relay devices are balanced with each other.

For example, if the data transmission prediction amount to the user apparatuses 1 to 6 served by the relay apparatus 1 810 is 100 and the data to the user apparatuses 7 to 7 served by the relay apparatus 2 820 It can be assumed that the transmission prediction amount is 30. In this case, the number of user apparatuses that change the relay apparatuses may be determined in order to match the sizes of the data transmission predictions of the relay apparatuses 1 810 and the relay apparatuses 820. [

If the data transmission prediction amount for the user apparatus 4 is 40, the data transmission prediction amount for the user apparatus 5 is 20, and the data transmission prediction amount for the user apparatus 6 is 10, only the user apparatus 4 is reallocated to the relay apparatus 2 820, The user apparatus 5 and the user apparatus 6 are reallocated to the relay apparatus 2 820 so that the balance between the data transmission predicted values of the relay apparatus 1 810 and the relay apparatus 2 820 can be balanced.

8, it is assumed that the relay device 1 810 and the relay device 2 820 are not the master relay device 800, and the master relay device 800 adjusts the allocation of the user device. If the relay apparatus 1 810 or the relay apparatus 2 820 is the master relay apparatus 800, the allocation to the direct user apparatus can be adjusted.
