The present invention relates to an integrated personal network service system and a control method thereof, and more particularly, to support each CPNS device included in a converged personal network service (hereinafter referred to as "CPNS"). By setting the category according to the function to perform the service, when the service request to the CPNS device only the service request that can be supported according to the category of the CPNS device, and if the service that can not be performed is requested, the service requester notifies the fact, operating efficiency of CPNS The present invention relates to an integrated private network service system and a method of controlling the same, which can improve the system performance and prevent waste of message resources in transmitting an inappropriate service request message.

The Open Mobile Alliance (OMA), which is responsible for application standards, proposed the Converged Personal Network Service (hereinafter referred to as "CPNS").

CPNS constitutes a personal network consisting of a combination of a device serving as a gateway that communicates with an external network and a device that plays actual services and content, and the device that plays actual services and content serves as a gateway. It is a service that enables a corresponding service or content to be provided by accessing a service / content providing unit that exists in an external network through a device that performs the service.

A device acting as a gateway in such CPNS is called a PN gateway, and a device connected to the PN gateway through local area communication and connected to an external network through the PN gateway is called a personal network entity (PNE). And a personal network device that serves to provide content and services of an external network to devices of a private network at the request of a PN gateway is called a CPNS device.

PNE included in CPNS can be applied to a variety of devices from high-end devices such as computers, smartphones, TVs, low-end devices such as sensors, blood pressure monitors.

In the case of low-end devices such as sensors and blood pressure monitors, it is not easy to apply the CPNS standard because the processing capability is limited and the functions that can be performed are limited. In addition, in the case of a low-spec device it is difficult to use the service because smooth communication is difficult. In addition, when a device having a high specification sends a message to a device having a low specification, a message resource is consumed because the sender continuously transmits the message to receive a response even though the receiver cannot respond to the message.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problem, and sets a category according to a function supported by each device for a CPNS device included in a Converged Personal Network Service (hereinafter referred to as "CPNS"). When the service request is made to the CPNS device, only the service request that can be supported according to the category of the corresponding CPNS device is processed, and when a service that cannot be performed is requested, the service requester is notified of the fact, so that the operation efficiency of the CPNS can be improved.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description will be presented a representative embodiment in the present invention for achieving the above technical problem. Also, for convenience of description of the present invention, names of entities defined in the Converged Personal Network Service (CPNS) of the Open Mobile Alliance (OMA), which is an application standard organization of a mobile terminal, will be used. However, these standards and names are used in the scope of the present invention. The present invention is not limited thereto, and is applicable to systems having a similar technical background.

1 is a control block diagram of a Converged Personal Network Service (hereinafter referred to as "CPNS") system in accordance with one embodiment of the present invention. CPNS may form a private network between devices capable of short-range communication, and deliver a service provided by an external network through the private network.

As shown in FIG. 1, the CPNS system includes at least one Personal Network Entity (hereinafter referred to as PNE) 300 and a Personal Network Gateway (hereinafter referred to as PN Gateway). And a CPNS device 100.

The PNE 300 forms a private network by performing pairing with the PN gateway 200 through short-range communication. The PNE 300 checks the presence or absence of CPNS support between two devices, checks the availability of CPNS through authentication / authorization, and checks the role between devices to provide a CPNS network in terms of applications. Can be formed.

The PNE 300 is a device that directly provides a service, and each PNE 300 is equipped with a CPNS service providing function. Commonly provided CPNS service functions, various functions such as authentication, registration, security, group function, service search function, service distribution function is provided.

However, the PNE 300 may include various devices from high-end devices such as PCs, smartphones, and tablets to general devices such as navigation and PMP, and low-end devices such as sensors and blood pressure monitors.

Accordingly, different CPNS functions can be supported according to the PNE, and the category of the corresponding PNE is determined according to the functions supported by the PNE. The category is to classify CPNS devices such as PNE 300 and PN gateway 200 into a plurality of groups according to the types of CPNS services that can be performed in each device. For example, among various CPNS functions such as authentication, registration, security, group function, service search function, service distribution function, a category may be set according to which function can be supported, and the setting process of such a category may be performed by the CPNS manager. Can be performed.

When the CPNS device, that is, the PNE 300 and the PN gateway 200 transmits a service registration request message or a service providing request message, the CPNS device attaches the category information to which it belongs.

When the receiving device needs to process the requested service, if the service that can handle the normal service but cannot process the service can return the category information to inform the fact that the service can not be processed.

If the receiving device needs to deliver the requested service to another device, it determines whether the service can be processed by checking the category of the device to receive the message, and if the service is processable, delivers the message normally. If the service is not available, stop message delivery. Here, the service non-processing message indicating that the corresponding service cannot be processed by returning category information of the device to which the message is to be sent to the device side that has sent the message.

The PN gateway 200 may access the CPNS device 100 existing in the external network. In addition, the private network 30 may be formed with the PNEs 300 and may perform a function of relaying CPNS system messages and service or content transmission between the CPNS device 100 and the PNE 300. The PN gateway 200 delivers the service to the CPNS device 100 when the PNE 300 included in the private network requests a service, and delivers the data to the PNE 300 when data is provided through the external network. . The PN gateway 200 includes a module capable of communicating both WAN and PAN remote / near distances such as, for example, a mobile phone, a PDA, a set top box, a Wi-Fi AP, a Wibro egg, and a mobile AP of a smartphone. It may include.

The PN gateway 200 registers the private network 30 formed with the PNEs 300 to the CPNS device 100. When the private network 30 is registered, the category information of the PN gateway 200 and the PNEs 300 is provided together to register the category information of each device in the CPNS apparatus 100 together.

The CPNS device 100 registers and manages the PN gateway 200 and the PNE 300 according to a registration request of the PN gateway 200. The CPNS device 100 stores and manages category information of each PN gateway 200 and PNE 300.

When the CPNS device 100 needs to request service provision from the PNE 300, the CPNS device 100 checks category information of the corresponding PNE, and delivers it to the PNE if the corresponding PNE is a service request that can be processed. On the other hand, if the service can not be processed by the PNE CPNS device 100 returns a message that the service is unavailable to the user requesting the service. The message indicating that the service is unavailable may attach the category information of the receiving PNE as a reason of the error.

2 is a control block diagram of a CPNS device 100 of a CPNS system according to an embodiment of the present invention.

As shown in FIG. 2, the CPNS device 100 includes a communication interface 110, a PN gateway information manager 120, a PNE information manager 130, a service processor 140, a category information provider 150, And a database 180.

The communication interface 110 transmits and receives data through an external network such as the Internet or a mobile communication network.

The PN gateway information manager 120 stores and manages information of the PN gateway 200 in the database 180. PN gateway information, category information of the PN gateway, and includes at least one or more of the ID of the PN gateway, the ID of the connected PNE (300), the provided service, billing information, specification information of the connected PNE (300), or a combination thereof. do.

The PNE information manager 130 stores and manages information of the PNE 300 that transmits / receives information to / from the PN gateway 200 through a local area wireless communication network in the database 180.

The information of the PNE 300 includes category information of the PNE 300. In addition, at least one or more of an ID of the PNE 300, an ID of the connected PN gateway 200, provided services, billing information, service-related information, or a combination thereof, and the service-related information may include a plan, a transmission rate, or a combination thereof. At least one or more of the combinations.

The category information providing unit 150 provides service information supported according to a category. For example, devices in the first category provide authentication and security functions, devices in the fifth category provide authentication, security and group management functions, and other defined categories may also provide different functions. The category information providing unit 150 stores the category defined in this way and information about a service supported by the category.

Meanwhile, the policy for classifying categories may be set in various ways by the operator. For example, a policy for classifying the PNE 300 into a specific category may be set according to whether services such as authentication, security, PN registration, group function, service fabrication, and remote control function can be provided. .

The service processor 140 receives and processes a CPNS service requested by the PNE 300 through the PN gateway 200. For example, when the PNE 300 requests to provide specific content, the PNE 300 transmits the corresponding content to the PNE 300 through the PN gateway 200.

When the service processor 140 transmits a service request message, the service processor 140 checks the category of the receiving PNE 300 or the PN gateway 200 so that the receiving PNE 300 or the PN gateway 200 may process a service included in the message. Determine whether you can.

As a result of the category check of the receiving PNE 300 or the PN gateway 200, if it is determined that service processing is possible, the service request message is normally transmitted, and the service processing is impossible at the corresponding PNE 300 or the PN gateway 200. If confirmed, stop sending the message. In addition, a service non-processing message may be returned by attaching category information of the receiving PNE 300 or the PN gateway 200.

The database 180 stores information related to operation of the CPNS device 100 and information related to CPNS provision, such as PN gateway information and CPNS device information.

3 illustrates a category policy table of an integrated private network service system according to an embodiment of the present invention.

CPNS devices range from high-end devices such as PCs, smartphones and tablets to low-end compact devices such as personal media devices such as navigation and PMP, sensors and blood pressure monitors.

High-end devices can also function as PN gateways and can offer a wide variety of features, including authentication for security, service registration and retrieval, service description management, and group management.

On the other hand, low-end devices such as sensors and blood pressure monitors have limited functions.

As such, each device may support different functions according to hardware and software characteristics, and thus, categories may be set according to functions supported by each device.

4 is a flowchart illustrating an integrated private network service method according to a first embodiment of the present invention, and illustrates a method for initial setting of a CPNS system.

In order to use the CPNS service, the PNE 300 searches for the PN gateway 200 to serve as a personal network gateway device (S110).

The PNE 300 requests a service to the found PN gateway 200. Here, the PNE 300 also transmits its category information (S112).

The PN gateway 200 checks whether the PNS 300 is capable of CPNS service (S114).

As a result of the check, if the CPNS service of the PNE 300 is possible, the PN gateway 200 transmits an authentication message indicating that the CPNS service is available to the PNE 300 (S116).

When the PNE 300 receives the authentication message indicating that the CPNS service is available from the PN gateway 200, the PNE 300 transmits its ID (S118).

The PN gateway 200 checks whether the format of the ID transmitted from the PNE 300 matches the ID format issued by CPNS (S120), and if the format matches, the service is available to the PNE 300. Send an authentication message (S122).

Thereafter, the PN gateway 200 transmits authentication information, ID, and category information of itself and the PNE 300 to the CPNS device 100 (S124).

The CPNS device 100 checks the authentication information and ID transmitted from the PN gateway 200 to determine whether the CPNS service is available, and the category information, authentication information, ID, etc. of the PNE 300 and the PN gateway 200. The information is registered (S126).

If both the PN gateway 200 and the PNE 300 are available, the CPNS device 100 notifies this to the PNE 300 so as to perform a CPNS service including a content request thereafter (S128).

5 is a flowchart of a method of integrated private network service according to a second embodiment of the present invention, which illustrates a service providing method using category classification.

The CPNS device 100 registers a category of the PNE 300 together with the registration of the PNE 300 (S210).

In a state in which category information of the PNEs 300 is registered, the first PNE may request a message transmission from the second PNE side (S212).

The CPNS device 100 checks a category to which the first PNE and the second PNE belong (S214). For example, the first PNE may belong to category X and the second PNE may belong to category Y.

If Y is greater than X (Y> X), i.e., if the second PNE to send the message belongs to a category that provides relatively high service than the first PNE to request sending the message, Y may first request a specific message. And X can respond without a problem (S216).

If X is greater than Y (Y <X), that is, if the first PNE requesting the message belongs to a category that provides a relatively high specification of services, some messages sent by X because X has more features to support Y does not respond, and only an error message according to a category is received (220). Here, Y may return its category value.

When X and Y are the same (X = Y), since the functions supported by each other are the same, desired communication is possible between each other (S218).

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.

According to the present invention, it is possible to use a service that meets the specifications of each device, so that CPNS can be applied even to a low-spec device, and when the message is transmitted between devices, the receiver has a low specification. The present invention can be used for a CPNS system and a control method thereof that can reduce message resource consumption.
