Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In the following detailed description, exemplary embodiments of the present invention will be described. In order to facilitate the description of the present invention, the names of the entities defined in CPNS (Converged Personal Network Service) of OMA (Open Mobile Alliance), which is an application standard mechanism of the mobile terminal, will be used. However, But it is obvious that the present invention is applicable to a system having a similar technical background.

1 is a control block diagram of a Converged Personal Network Service (CPNS) system according to an embodiment of the present invention. CPNS can form a private network between devices capable of short-range communication, and can deliver services provided from an external network through a private network.

1, the CPNS system includes at least one Personal Network Entity (hereinafter referred to as PNE) 300, a Personal Network Gateway (hereinafter referred to as a PN gateway) (200), and a CPNS device (100).

The PNE 300 performs a pairing with the PN gateway 200 through short-range communication to form a private network. The PNE 300 confirms the availability of CPNS between two devices, verifies the availability of the CPNS through authentication / authorization, confirms the role between the devices, Can be formed.

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

However, the PNE 300 may include various devices ranging from high-end devices such as PCs, smart phones, tablets, general devices such as navigation devices, PMPs, and low-end devices such as sensors and blood pressure gauges.

Therefore, different PNNS 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 categories are classified into a plurality of groups according to the types of CPNS services that can be performed by the respective devices, such as the PNE 300 and the PN gateway 200. For example, a category can be set according to a function of a variety of CPNS functions such as authentication, registration, security, group function, service search function, service distribution function, and the like. .

The CPNS device, that is, the PNE 300 and the PN gateway 200, together with the category information to which the CPNS device belongs, transmits the service registration request message or the service provision request message.

When the receiving-side device has to process the requested service, it can notify the fact that it can not process the service if it can process the service normally but can not process it, by returning its category information.

When the receiving-side device needs to deliver the requested service to another device, it checks the category of the device to which the message is to be delivered, determines whether or not the service can be processed, and if it is a processable service, If the service can not be done, stop delivering the message. Here, it is possible to send the service process disable message that the device that has sent the message can return the category information of the device to which the message is to be delivered and can not process the service.

The PN gateway 200 can access the CPNS device 100 existing in the external network. The PNE 300 and the PNE 300 may form a private network 30 and relay the CPNS system message and service or content transmission between the CPNS device 100 and the PNE 300. When the PNE 300 included in the private network requests the service, the PN gateway 200 delivers the PNE 300 to the CPNS 100. When the data is provided through the external network, the PN gateway 200 transmits the PNE 300 to the PNE 300 . The PN gateway 200 is a module capable of communicating with both the WAN and the PAN remote / short-distance, for example, a mobile phone, a PDA, a set top box, a WiFi AP, a Wibro egg, . ≪ / RTI >

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

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 the category information of each PN gateway 200 and the PNE 300.

If the CPNS device 100 requests the PNE 300 to provide a service, the CPNS device 100 checks the category information of the corresponding PNE. If the PNE 300 can process the service, the CPNS device 100 transmits the service request to the PNE. On the other hand, if the PNE can not process the service, the CPNS device 100 returns a message indicating that the service is unavailable to the user requesting the service. The message indicating that the service is unavailable may be accompanied by category information of the receiving PNE as the reason for the error.

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

The PN gateway information management unit 120 stores and manages the 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, the billing information, the specification information of the connected PNE 300, do.

The PNE information management unit 130 stores and manages information of the PNE 300 that transmits and receives information to and from the PN gateway 200 through the short-range wireless communication network.

The information of the PNE 300 includes the category information of the PNE 300. The service related information includes at least one of an ID of the PNE 300, an ID of the connected PN gateway 200, a provided service, a billing information, a service related information, or a combination thereof. And combinations thereof.

The category information providing unit 150 provides service information supported according to the category. For example, the devices of the first category provide authentication and security functions, the devices of the fifth category provide authentication, security, and group management functions, and other defined categories may provide different functions. The category information providing unit 150 stores the category and the information on services supported by the category.

On the other hand, such a category classification policy can be set in various ways by the operator. For example, a policy may be set to classify the PNE 300 into a specific category depending on whether it can provide services such as authentication, security, PN registration, group function, service fabrication, and remote control function .

The service processing unit 140 receives and processes the CPNS service requested by the PNE 300 through the PN gateway 200. For example, when the PNE 300 requests to provide a specific content, the content is transmitted to the PNE 300 through the PN gateway 200.

The service processing unit 140 identifies the category of the receiving PNE 300 or the PN gateway 200 when the service request message is transmitted so that the receiving PNE 300 or the PN gateway 200 processes the service included in the message Or not.

If it is confirmed that the service processing is possible as a result of the category check of the receiving PNE 300 or PN gateway 200, the service request message is normally transmitted and the PNE 300 or the PN gateway 200 can not process the service If so, stop sending the message. In addition, it is possible to attach a category information of the receiving PNE 300 or the PN gateway 200 to return a service disabling message.

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

FIG. 3 illustrates a category policy table of an integrated personal 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 personal media devices such as navigation devices and PMPs, to low-end compact devices such as sensors and blood pressure monitors.

In the case of high-end equipment, it can also function as a PN gateway, and can provide relatively various functions such as authentication for security, service registration and retrieval, service description management, and group management.

On the other hand, functions that can be supported for low-end devices such as sensors and blood pressure monitors are limited.

Thus, each device can support different functions depending on hardware and software characteristics, and categories can be set according to functions supported by each device.

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

In order to use the CPNS service, the PNE 300 searches for a PN gateway 200 serving as a PN (Personal Network) Gateway Device (S110).

The PNE 300 requests service from the searched PN gateway 200. Here, the PNE 300 also transmits its own category information (S112).

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

If it is determined that the CPNS service of the PNE 300 is available, the PN gateway 200 transmits an authentication message indicating that the CPNS service is available to the PNE 300 (S116).

Upon receiving 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 the CPNS (S120). If the formats match, the PN gateway 200 can perform service with the PNE 300 (S122).

Then, 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 apparatus 100 checks the authentication information and the ID transmitted from the PN gateway 200 to determine whether or not the CPNS service is available and transmits the category information of the PNE 300 and the PN gateway 200, Information is registered (S126).

If both the PN gateway 200 and the PNE 300 are able to provide services, the CPNS device 100 notifies the PNE 300 of the service, and then enables CPNS service including the content request (S128).

FIG. 5 is a flowchart illustrating a method of providing an integrated personal network service according to a second embodiment of the present invention.

The CPNS device 100 registers the category of the PNE 300 together when the PNE 300 is registered (S210).

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

The CPNS apparatus 100 confirms the 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 larger than X (Y> X), that is, if the second PNE to which the message is to be transmitted belongs to a category providing a relatively high-grade service, then Y may request a specific message first And X can respond without any problem (S216).

If X is greater than Y (Y <X), that is, if the first PNE requesting message transmission belongs to a category providing relatively high-level services, then X supports more features, Y is not responded to, and only an error message according to the category is received (220). Here, Y can return its own category value.

When X and Y are the same (X = Y), the desired functions are the same as each other, and desired communication is possible between them (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.

The present invention makes it possible to use CPNS even in the case of a low-end device by making it possible to use a service conforming to the specification of each device, and when a message is sent to an inappropriate device at the time of message transmission between devices, The CPNS system and the control method thereof, which can reduce message resource consumption.
