Description

Technical Field [0001] The present invention relates to a system and a method for providing a remote control service in a CPNS environment,

The present invention relates to a system and method for providing a remote control service in a CPNS (Converged Personal Network Service) environment, and more particularly, to a system and method for providing a remote control service in a CPNS And transmits a service search request signal including the specific terminal identification information to the CPNS device to receive a service list that the specific terminal can support And transmits a service execution request signal for requesting execution of the selected service to the CPNS device when the specific service desired to be executed in the specific terminal is selected from the service list, In a CPNS environment that provides a remote control service Ball relates to systems and methods.

The Open Mobile Alliance (OMA), which is responsible for application application standards, has proposed a Converged Personal Network Service (CPNS).

CPNS is a personal network composed of a combination of a device serving as a gateway responsible for communication with an external network and a device reproducing real service and contents, and a device for reproducing the actual service and the content serves as a gateway To a service providing apparatus existing in an external network through a device that performs a service for providing a service or a content. A device acting as a gateway in the CPNS is referred to as a PN (Personal Network Network), and a device connected to the PN gateway through short-range communication and connected to an external network through a PN gateway is referred to as a PNE (Personal Network Entity).

The number of devices that make up the private network can be changed dynamically. For example, a new PNE can join a private network after one PN gateway and one PNE form the first private network.

1 illustrates a service management method in a conventional CPNS environment.

Referring to FIG. 1, when a PNE transmits a personal network connection request message including content / service information to a PN gateway (S104), the PN gateway authenticates whether the PNE is a CPNS user and forms a private network And performs authentication / approval to confirm whether the authentication is permitted (S106). The PNE is physically paired with the PN gateway through each short range communication unit before performing the above process.

Then, the PNE transmits a mode search message to all the devices paired with the PNE through the local communication unit in order to find the neighboring PN gateway or to understand what mode the neighboring device operates in relation to the CPNS. When the PN gateway receives the mode search message, the PN gateway transmits a response message to the PN gateway by including information indicating the PN gateway in the response message.

After the above process is performed, the PNE transmits a Personal Area Connection Request message to the PN gateway, and the PN gateway performs authentication.

If it is determined in step S106 that the authentication is normally completed, the PN gateway assigns a PNE identifier to the PNE, and stores the PNE list including the assigned PNE identifier and the terminal information of the PNE (S108).

After performing step S108, the PN gateway constructs a PN list and transmits a PN registration request message to the CPNS device (S110). The PN registration request message may include PN gateway identification information, a PN identifier, a PNE list, terminal information for each PNE, content / service information of each PNE, and the like.

Upon receiving the PN registration request message, the CPNS device performs CPNS use authentication and authorization for the PNE included in the PN registration request message (S112), and registers the PN list including the content / service information of each PNE S114).

After the execution of S114, the CPNS device transmits a response message indicating that the PN registration is completed to the PN gateway (S116), and the PN gateway transmits a response message indicating that the private network connection is completed to the PNEn (S118 ).

After the formation and registration of the private network is completed as described above, when the PNE requests the CPNS service to the CPNS device through the PN gateway (S120), the CPNS device searches for the corresponding service (S122) To the PNE through the PN gateway (S124).

The foregoing and other objects, features, and advantages of the present invention will become more apparent from the following detailed description taken in conjunction with the accompanying drawings, in which: FIG.

2 is a diagram illustrating a remote control service providing system in a CPNS environment according to the present invention.

Referring to FIG. 2, a remote control service providing system in a CPNS environment includes one or more user terminals 100, a PN gateway 200, and a CPNS device 300.

The user terminal 100 has a built-in short-range communication unit and is capable of short-range communication with other nearby terminals. However, the user terminal 100 does not have a communication module capable of connecting to an external network (Wide Area Network) And the service is provided through the private network.

Accordingly, the user terminal 100 is hereinafter referred to as a Personal Network Entity (PNE).

The PNE 100 has a private network formed through the PN gateway 200. The PNE 100 requests and receives a list of terminals belonging to a private network including the PN network 100 from the CPNS 300, The CPNS device 300 transmits a service search request signal including specific terminal identification information to the CPNS device 300 to receive a service list that the specific terminal can support.

In addition, the PNE 100 transmits a service execution request signal for requesting execution of the selected service to the CPNS device 300 when a specific service is selected from the service list.

In addition, the PNE 100 may receive a list of services that the PNE 100 can support in response to the service search request signal from the CPSN device 300. In this case, when a specific service desired to be executed in the specific terminal is selected from the list of services that the PNE 100 can support, the PNE 100 transmits a service execution request signal for requesting execution of the selected service to the CPNS device 300 do. Here, the service execution request signal does not include specific terminal identification information but includes identification information of the terminal itself. Accordingly, the CPNS apparatus transmits the execution requested service to the PNE 100, and the PNE 100 transcodes the received service to the specification of the specific terminal so as to be executable in the specific terminal. And transmits it to the specific terminal through the PN gateway 200.

If the PNE 100 receives a remote control command from a user to control a service provided by the specific terminal while the specific terminal is executing a service provided from the CPNS device 300, And transmits the input remote control command to the specific terminal. Then, the specific terminal performs an operation corresponding to the remote control command for the currently received service.

The user interface unit 120 serves as an input unit for the user to input a command or a display unit for displaying the result of the command.

The private network formation management unit 140 performs a pairing through the PN gateway through the short-range communication unit 110 to form a private network. That is, the private network formation management unit 140 forms a private network by performing pairing through the PN gateway in short distance communication. The formation of the private network here means that the network is formed between the PNE and the PN gateway so as to confirm the role of each physical pairing device and to receive the CPNS. To do this, it confirms whether CPNS support is available between the PNE and the PN gateway, confirms whether the device is a CPNS-enabled device through authentication / authorization, and operates the device in the GW mode or in the PNE mode And to establish a network in terms of the application to provide CPNS by performing a series of procedures to confirm that the CPNS is available. Through the formed personal network, the PNE can access the CPNS device of the provider network by using the communication function of the PN gateway.

The UE list request signal includes PNE identification information. When the UE list request signal is transmitted to the CPNS device via the PN gateway, the UE list request signal includes PN gateway identification information, PNE identification information, and the like.

In addition, when a specific terminal is selected from the terminal list, the service remote control controller 150 transmits a service search request signal including specific terminal identification information to the CPNS device to receive a service list that the specific terminal can support . At this time, the service remote control controller 150 receives a list of services that the terminal can support, together with a list of services that the terminal can support.

When a specific service desired to be executed in the specific terminal is selected from the list of services that the specific terminal can support, the service remote control controller 150 transmits a service execution request signal for requesting execution of the selected service to the CPNS device send. Here, the service execution request signal includes the identification information of the specific terminal, and the CPNS device provides the corresponding service to the specific terminal by viewing the identification information of the specific terminal.

When a specific service desired to be executed in the specific terminal is selected from the list of services that the PNE itself can support, the service remote control controller 150 transmits a service execution request signal for requesting execution of the selected service to the CPNS device do. Here, the service execution request signal does not include specific terminal identification information but includes identification information of the terminal itself. Accordingly, the service remote control controller 150 receives the service requested to be executed from the CPNS device, transcodes the received service to the specification of the specific terminal so as to be executable in the specific terminal, To the terminal.

When the remote control command for controlling the service provided by the specific terminal is inputted through the user interface unit 120, the service remote control controller 150 transmits the remote control command through the PN gateway To the specific terminal.

The communication unit 310 performs communication with the PN gateway through an external network such as the Internet or a mobile communication network.

The terminal information database 320 stores PN gateway information, a PNE list (or terminal list), and terminal information of each PNE. Here, the terminal information is information on various services (or functions) and capabilities that each PNE (or other terminal) can provide, such as I / O interface, codec, display size, resolution, Speed, connected network type (e.g., Wi-Fi, 3G, 4G etc.).

When the PN list registration request message including the terminal information is received from the PN gateway through the communication unit 310, the registration manager 330 authenticates and authenticates the PNNS included in the PN list registration request message And stores the terminal information in the terminal information database 320.

When receiving the terminal list request signal from the PNE, the remote control terminal management unit 340 searches the terminal information database 320 to obtain the terminal list registered in the private network to which the PNE belongs, and transmits the terminal list to the PNE .

When the service discovery request signal including the specific terminal identification information is received from the PNE, the remote control terminal management unit 340 acquires a service list that the specific terminal can support using the specific terminal identification information, PNE. At this time, the remote control terminal management unit 340 searches the terminal information database 320 to determine whether there is a service that can be supported by the specific terminal. As a result of the determination, if there is a service that can be supported by the particular UE, the remote control terminal management unit 340 acquires a service list that the UE can support and transmits the service list to the PNE together with the service list capable of supporting the PNE.

If it is determined that there is no service list available for the specific UE, the remote control terminal management unit 340 transmits only the PNE supported service list to the PNE. The CPNS device 300 always provides the service list of the PNE that transmitted the service search request signal to the PNE by default.

That is, since the PNEs registered for each PN gateway are stored in the terminal information database 320, the remote control terminal management unit 330 may use the PNE identification information or the PN gateway identification information included in the terminal list request signal, Determine the private network to which the PNE belongs. Then, the remote control terminal management unit 330 obtains the terminal lists registered in the associated private network and transmits the list to the PNE.

In addition, the terminal information database 320 stores information on various services and capabilities that each terminal can provide, that is, services that each terminal can support. Therefore, the remote control terminal management unit 340 receives the service When the search request signal is received, the terminal can search the terminal information database 320 to obtain a service that the terminal can support, and transmit the service to the PNE. Herein, the terminal is referred to as a service that can be supported, but this is the same as the service provided by the terminal.

Upon receiving a service execution request signal including the terminal identification information and the service information from the PNE, the service processing unit 350 provides a service corresponding to the service information to the corresponding terminal. Here, the service information may be a list of one or more services requested to be executed.

In addition, when receiving a remote control command including specific terminal identification information from the PNE, the service processing unit 350 controls the specific terminal to perform an operation corresponding to the remote control command.

For example, if the remote control command is a service disabling command, the service processor 350 transmits a service disabling command to the specific terminal to stop the service currently being provided by the specific terminal.

The terminal list request signal includes PNE identification information, PN gateway identification information, and the like, and is transmitted to the CPNS device through a PN gateway.

When the step S406 is performed, the CPNS device determines the private network to which the PNE belongs using the PNE identification information or the PN gateway identification information, obtains the list of terminals registered in the determined private network (S408) PNE (S410). That is, the CPNS apparatus stores PNEs registered for each PN gateway, terminal information of each PNE, and the like. Accordingly, the CPNS device can determine the private network to which the PNE belongs using the PNE identification information or the PN gateway identification information.

In the CPNS device, service lists that can be supported by each PNE are registered.

If the user selects a specific terminal from the list of the terminals (S414), the PNE displays a list of terminals from the CPNS device (S412) To the CPNS device (S416).

That is, the PNE user selects a specific terminal to be operated remotely from the terminal list. Then, the PNE transmits a service search request signal for requesting a service list capable of remotely operating the specific terminal to the CPNS device.

If the step S416 is performed, the CPNS device acquires the service list provided by the specific terminal using the specific terminal identification information (S418), and transmits the service list of the specific terminal to the PNE (S420). That is, since the CPNS apparatuses are registered with service lists that can be supported by each PNE, the CPNS apparatus acquires the service list of the specific terminal using the specific terminal identification information, and transmits the obtained service list to the PNE Together with a list of possible services, to the PNE.

In step S422, the PNE displays a service list of the specific terminal (S422). When a specific service desired to be executed in the specific terminal is selected from the service list (S424), the PNE requests the execution of the selected service And transmits a service execution request signal to the CPNS device (S426).

Then, the CPNS device provides the execution-requested service to the specific terminal (S428).

When the PNE receives a remote control command for the specific terminal from the user while the specific terminal is receiving a service from the CPNS device, the PNE transmits the remote control command to the specific terminal through the PN gateway And the specific terminal can perform an operation corresponding to the remote control command. Here, the remote control command includes playing, stopping, volume control, character movement input in a game, and text input in a chat window.

At this time, the PNE displays the received terminal list.

When a specific terminal is selected from the list of received terminals (S608), the PNE transmits a service search request signal including specific terminal identification information to the CPNS device and receives a service list provided by the specific terminal (S610) . At this time, the PNE receives a list of services that the specific terminal and the PNE can support in response to the service search request signal, or receives only the service list that the PNE can support.

When the user of the PNE selects a specific service to be executed in the specific terminal from among the list of services that the PNE can support, the PNE transmits a service execution request signal for requesting execution of the selected service to the CPNS device. Then, when the service requested for execution is received from the CPNS device, the PNE transcodes the received service to the specification of the specific terminal so as to be executable in the specific terminal, and transmits the service to the specific terminal through the PN gateway send. Then, the specific terminal can receive the service requested by the PNE.

A case where the user of the PNE selects a specific service to be executed in the specific terminal from the list of services that the specific terminal can support will be described with reference to the drawings.

In step S610, the PNE displays a service list of the specific terminal. When a specific service desired to be executed in the specific terminal is selected from the service list of the specific terminal (S612), the PNE requests the execution of the selected service And transmits a service execution request signal to the CPNS device (S614). Then, the CPNS device provides the execution-requested service to the specific terminal.

At this time, when the remote control command for the specific terminal is inputted, the PNE transmits the remote control command to the specific terminal through the PN gateway, and can control the remote terminal even while the specific terminal is being provided with the service .

For example, suppose the refrigerator is a PNE1, but the smartphone is a PNE2, but has no UI control, so we will explain how PNE2 remotely controls PNE1.

In the CPNS device, PNE1, PNE2, and PN gateways are registered by forming a single private network.

When a PNE2 user capable of UI control selects the service remote operation menu, the PNE2 requests the CPNS device list to receive the list of terminals including PNE1 and PNE2.

When the PNE2 user selects PNE1 from the UE list, the CPNS device transmits the PNE1 service list to the PNE2, not the PNE2. For example, if the PNE1 resolution is HVGA and the PNE2 resolution is VGA, the CPNS device selects the content for HVGA and transmits it to the PNE2 because the actual receiving terminal is PNE1 even if the request comes from PNE2.

When the PNE2 user selects a specific service from the service list, the CPNS device provides the corresponding service to the PNE1.

Since PNE2 can continue to provide UI control, a terminal such as UI control and display which lacks specific functions can receive service because the terminal such as PNE2 compensates the function.

In addition, if the specific terminal can not execute a specific service even though it is included in the service list of the specific terminal, the PNE can transcode the specific service and transmit the specific service to the specific terminal. In this case, the PNE must have a function of transcoding.

7 is a flowchart illustrating a method of providing a CPNS device according to the present invention in a CPNS environment.

7, when the UE list request signal is received from the PNE (S702), the CPNS device determines the private network to which the PNE belongs using the PNE identification information or the PN gateway identification information, Acquires the registered terminal list, and transmits the list to the PNE (S704).

After the step S704, if a service search request signal including specific terminal identification information is received from the PNE (S706), the CPNS device determines whether there is a service available for the specific terminal using the specific terminal identification information (S708). That is, the CPNS apparatus searches the terminal information database and judges whether a service that the specific terminal can provide exists.

If it is determined in step S708 that there is a service that can be supported by the specific UE, the CPNS device acquires a service list supported by the specific UE and transmits the list to the PNE in step S710. At this time, the CPNS device transmits a list of services that the PNE can support together with a list of services that the specific terminal can support.

If the service execution request signal is received from the PNE in step S712 after the execution of step S710, the CPNS device provides the execution-requested service to the specific terminal in step S714. Since the service execution request signal includes the identification information of the specific terminal, the CPNS device provides the requested service to the specific terminal by viewing the identification information of the specific terminal.

If it is determined in step S708 that the service can not be supported by the particular UE, the CPNS device obtains a service list that the PNE can support and transmits the service list to the PNE in step S716.

If the service execution request signal is received from the PNE in step S718 after the execution of step S716, the CPNS device transmits the execution requested service to the PNE in step S720. Here, since the service execution request signal includes the identification information of the PNE, the CPNS device transmits the service requested for execution to the PNE.

Then, the PNE converts the provided service into a specification of the specific terminal so as to be executable in the specific terminal, and transmits the converted service to the specific terminal through the PN gateway.

According to another aspect of the present invention, there is provided a method for controlling a CPNS device, the method comprising: (a) requesting and receiving a list of terminals included in a personal network to which the CPNS device belongs when the service remote operation menu is selected by the user; (C) transmitting a service search request signal including specific terminal identification information to the CPNS device to receive a service list that the specific terminal can support; (c) And transmitting a service execution request signal for requesting execution of the selected specific service to the CPNS device when a specific service is selected, in a CPNS environment, Is provided.

According to another aspect of the present invention, when a terminal list is requested from a private network entity through a PN gateway, the terminal list database is searched to acquire a terminal list registered in a private network to which the private network entity belongs, If the service discovery request signal including the specific terminal identification information is received from the private network entity, the presence or absence of a service that can be supported by the specific terminal is determined using the specific terminal identification information, Acquiring a service list that can be supported by the specific terminal or a list of services that the private network entity can support according to a result and transmitting the service list to the private network entity; When the request signal is received, To provide a remote control service in a CPNS environment, comprising the steps of: providing a service corresponding to the service information are recorded to the program is provided with a recording medium readable in the electronic device.

A method for providing a remote control service in a CPNS environment can be created by a program, and the codes and code segments constituting the program can be easily deduced by a programmer in the field.

Thus, those skilled in the art will appreciate that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. It is therefore to be understood that the embodiments described above are to be considered in all respects only as illustrative and not restrictive. The scope of the present invention is defined by the appended claims rather than the detailed description and all changes or modifications derived from the meaning and scope of the claims and their equivalents are to be construed as being included within the scope of the present invention do.

In the present invention, when there is no UI that can be manipulated with respect to an interconnected PNE, or when there is a PNE that is difficult to mount various services, a service to be provided to the PNE is controlled by another PNE capable of self- The present invention can be applied to a system and method for providing a remote control service in a CPNS environment.
