Description

Apparatus and method for assigning unique URI}

The present invention relates to an apparatus and method for allocating URIs.

In general network protocols, the physical location is the end point, but the SIP (Session Initiation Protocol) operates as the endpoint regardless of the location. For example, a public switched telephone network (PSTN) type telephone is recognized as the same entity at the same physical location, but a SIP type telephone is always recognized as the same entity regardless of the place of use. Thus, when using SIP, it is possible to ensure very excellent personal mobility.

Due to the advantages described above, SIP has been in the spotlight as a killer protocol of Next Generation Network (NGN). However, in SIP communication, a Uniform Resource Identifier (URI) is used as a recognition means for each product. The conventional SIP standard does not propose a method for allocating a unique URI for each product, and there is a possibility that URIs may collide between products, thereby preventing seamless personal mobility.

The technical problem to be achieved by the present invention is to provide a device and method that can ensure smooth personal mobility by eliminating the possibility of collision of URI between products by assigning a unique URI for each product.

The unique URI allocation apparatus according to the present invention for solving the above technical problem is a unique URI request message receiving unit for receiving a unique URI request message that is a message requesting a unique URI that is a URI to be assigned only to a predetermined product; A unique URI storage checking unit that checks whether the unique URI is stored when the unique URI request message is received in the URI request message receiving unit; And a unique URI generating unit generating the unique URI when the unique URI storing confirmation unit determines that the unique URI is not stored.

According to another aspect of the present invention, there is provided a unique URI allocation method comprising the steps of: (a) receiving a unique URI request message which is a message for requesting a unique URI which is a URI to be assigned only to a predetermined product; (b) when the unique URI request message is received in step (a), checking whether the unique URI is stored; And (c) if it is determined in step (b) that no unique URI is stored, generating the unique URI.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram of a SIP capable network system according to an embodiment of the present invention.

Referring to FIG. 1, a SIP enabled network system includes an application layer 11, a SIP application 12, a SIP stack 13, a transport layer 14, a physical layer 15, and a UURI. Storage 16.

The illustrated application layer 11, SIP application 12, SIP stack 13, transport layer 14, and physical layer 15 follow the Open Systems Interconnection (OSI) reference model. Here, the SIP application 12 and the SIP stack 13 correspond to a session layer, which is seven layers of the OSI reference model. When the user powers on a product equipped with a SIP-capable network system, the application layer 11 reads a unique URI stored in the UURI (Unique URI) storage 16, and the read unique URI is sent to the SIP application 12. Is passed. The SIP application 12 and the SIP stack 13 use this unique URI to establish a session with the other party. Therefore, in order to apply SIP according to the present invention, a unique URI must always be stored in nonvolatile storage. The transport layer 14 corresponds to four layers of the OSI reference model, for example, a Real-time Transport Protocol (RTP). The physical layer 15 corresponds to layer 1 of the OSI reference model, and examples thereof include a coaxial cable and a digital subscriber line (DSL).

2 is a block diagram of a unique URI allocation apparatus according to an embodiment of the present invention.

Referring to FIG. 2, the unique URI assignment apparatus 2 includes a unique URI request message receiving unit 21, a unique URI storage checking unit 22, a unique URI generating unit 23, a unique URI loading unit 24, and a unique URI. URI storage section 25 is configured. The unique URI assignment apparatus 2 is mounted in the application layer 11 of FIG.

The unique URI request message receiving unit 21 receives a unique URI request message which is a message for requesting a unique URI which is a URI to be assigned only to a predetermined product. In general, a unique URI request message is received from the initialization module 1 which is driven when power is applied to this product. The initialization module 1 may be regarded as a part that is initially driven when power is applied from the power supply 4 and is executed during a booting process. Since the unique URI is required before the SIP session is established for the SIP communication to ensure smooth personal mobility, the initialization module 1 requests the unique URI assignment device 2 to assign a unique URI.

When the unique URI request message is received by the URI request message receiving unit 21, the unique URI storing confirmation unit 22 confirms whether or not the unique URI is stored in the unique URI storing unit 25. In some cases, a unique URI is already stored in a product with a predetermined name by the manufacturer, and when a user uses the product for the first time after the product is released, it may be automatically generated in a certain manner within the product.

3 is a diagram illustrating a process of inserting a unique URI when manufacturing a product according to an embodiment of the present invention.

Referring to FIG. 3, the product is assembled (31), a predetermined URI is inserted into the assembled product so that the manufacturer can be distinguished for each product, and the inserted product is tested (32). Packed and shipped (33). As such, when a unique URI is pre-determined and inserted into a product in a manufacturing step, there is an advantage that a collision between URIs cannot occur, but there is an inconvenience that a manufacturer must determine a unique URI.

When the unique URI is inserted at the time of manufacturing the product as shown in FIG. 3, when the user applies power to the product to drive the product, the unique URI storing checking unit 22 may read-only memory such as a ROM (Read Only Memory) or the like. Confirm that the unique URI is already stored in the unique URI storage unit 25 implemented as.

At this time, when the unique URI loading unit 24 confirms that the unique URI is stored in the unique URI storage confirming unit 22, the unique URI loading unit 24 loads the unique URI confirmed to be stored in the SIP application module 3. The SIP application module 3 performs communication according to SIP using the loaded unique URI.

4 is a diagram illustrating a process of inserting a dummy URI when manufacturing a product according to an embodiment of the present invention.

Referring to FIG. 4, the product is assembled (31), and the product is tested by inserting a test unique URI in order to find out that the product operates properly in a state where the unique URI is inserted (42). If tested for good, insert a dummy unique URI into the product. The dummy unique URI is a meaningless URI, and the actual unique URI is generated by itself when the product is started. It is checked whether the dummy unique URI is normally inserted, that is, whether the unique URI is normally reset (43), and if it is confirmed that the dummy unique URI is normally reset, the product is packed and shipped (44). As such, the inconvenience of the manufacturer having to define the unique URI in the manufacturing stage, in which the unique URI is generated by the product itself in the product use stage, can be resolved, but conflicts between the unique URIs may occur according to the method of defining the unique URI. The disadvantage is that it can.

As shown in FIG. 4, when a dummy URI is inserted at the time of manufacture of the product, when the user applies power to the product to drive the product, the unique URI storage checking unit 22 may be a nonvolatile memory such as a flash memory. It is confirmed that the dummy URI is stored in the implemented unique URI storage unit 25 and the actual unique URI is not stored. The dummy URI may be set to 1 bit such as 0 or 1 for quick confirmation.

The unique URI generation unit 23 generates a unique URI when the unique URI storage confirmation unit 22 determines that the unique URI is not stored in the unique URI storage unit 25. For example, the unique URI generator 23 generates a unique URI by combining at least one or more of additional information of the product, a serial number of the product, a domain name of the product, and an IP address of the product. If the unique URI to be generated in this way is expressed as a function, it is as follows.

f_uuri = combination of (f_ad, f_sno, f_dname, ipadr)

Where f_uuri = function for anique URI generation

f_ad = function for auxiliary data generation

f_sno = function for serial number generation

f_dname = function for domain name

ipadr = (public or private) IP address

f_ad = combination of (vid, ptype, pname, pid, mname, mid, ...)

Where f_ad = function for auxiliary data generation

vid = vendor ID

ptype = product type

pname = product name

pid = product ID

mname = model name

mid = manufacturer ID

f_sno = combination of (num, datetime, hvalue, evalue)

Where f_sno = function for serial number generation

num = (ordinalor random) number

datetime = combination of (date, time)

hvalue = hashed value

evalue = (encoded or encrypt) value

f_dname = combination of (pcl, pca, ptype, rd) + parent domain name

Where f_dname = function for Domain Name

pcl = product class

pca = product category

ptype = product type

rd = related (department or organization)

Examples of the unique URI generated through the unique URI generation function described above include helpdesk114@samsung.com and pda20030121337@sipd.samsung.com.

The unique URI storage unit 25 stores the unique URI generated by the unique URI generation unit 24. At this time, the unique storage URI verification unit 22 again checks whether the unique URI storage unit 25 stores the unique URI, and the unique URI loading unit 24 stores the unique URI in the unique URI storage confirmation unit 22. If it is confirmed that it is, the unique URI that is confirmed to be stored in the SIP application module 3 is loaded.

In this way, if a unique URI is assigned to each product, since a unique URI is generated in the product itself even if a user does not have a special setting in the SIP application product, personal mobility may be provided only by the basic setting. In addition, since the possibility of URI collisions between products is eliminated, it is possible to increase the scalability of the SIP solution to be operated in the next generation network, and to prevent the URI collision due to user carelessness in advance. Each product can be identified and recognized by a unique URI, making it easy to implement multiple consumer electronics application solutions. In other words, it is possible to prepare a foothold for the next generation product development by receiving the user use pattern, and if a problem occurs in the product, it is possible to automatically connect with the A / S center for user convenience, and to control the product remotely. Can be used as a point.

5 is a flowchart of a unique URI allocation method according to an embodiment of the present invention.

Referring to FIG. 5, the unique URI allocation method includes the following steps.

A unique URI request message, which is a message for requesting a unique URI that is a URI to be assigned only to a predetermined product, is received (51). Here, the unique URI request message is received from the initialization module that is driven when the power is applied to the product. Subsequently, if a unique URI request message is received, it is checked whether the unique URI is stored (52). If it is determined that the unique URI is stored (53), then the unique URI identified as being stored in the SIP application module is loaded (54). If it is confirmed that no unique URI is stored (53), then a unique URI is generated (55). Here, a unique URI is generated by combining at least one of additional information of the product, serial number of the product, domain name of the product, and IP address of the product. The generated unique URI is then stored 56. Again, the process returns to step 52 to confirm whether or not to store the unique URI (52), and then load the unique URI confirmed to be stored in the SIP application module (54).

Meanwhile, the above-described embodiments of the present invention can be written as a program that can be executed in a computer, and can be implemented in a general-purpose digital computer that operates the program using a computer-readable recording medium.
