The development of information and communication technology is changing the networking and internet environment centered on computers such as personal computers or notebook computers to small devices that can be moved such as smart phones, PDAs and portable multimedia devices including computers. However, small devices capable of arithmetic, communication, and networking functions can be attached to general objects such as meters and thermometers as well as information devices. These small devices attached to objects can automatically acquire information of objects or mutually share information through communication networks between objects.

The term IoT, M2M, and object intelligence communication refers to concepts and technologies for connecting objects to a network using a communication device attached to the object or configuring a communication network between objects to share information.

In this network environment, communication network between object and object as well as person-to-person and person-to-object communication becomes possible and information sharing among all objects becomes possible, which is an essential technical element for evolving into the future ubiquitous information service society.

M2M (Machine To Machine) is a communication between a machine and a machine. All the devices around us communicate information to the other devices by using sensors to respond to each other so that humans can live comfortably and conveniently. The amount of M2M-related devices used increases, and the data traffic increases due to the increase in transmission / reception data capacity, which causes various overloads such as congestion of networks due to resource naming and M2M traffic, and related servers .

Such M2M signals and control traffic can have a huge adverse effect on a network that transmits existing voice and data traffic, which can cause unreliability of existing services, which can cause significant damage to the carrier.

Therefore, there is a need for an operational management method that can manage M2M traffic separately.

As related prior art, Korean Patent Laid-Open Publication No. 2014-0047314 (published on April 24, 2014, entitled " M2M network resource allocation method and apparatus ") is available.

The present invention is to provide an IMS platform management apparatus for M2M traffic that efficiently manages resources by virtualizing an IMS platform.

In addition, the present invention provides an IMS platform management apparatus for M2M traffic that manages the system's ad hoc management and network over-concentration by distributing M2M traffic.

The technical objects to be achieved by the present invention are not limited to the above-mentioned technical problems.

According to another aspect of the present invention, there is provided an IMS platform management apparatus for M2M traffic, comprising: a network configuration information unit having M2M policy management information and topology network information; an M2M signal storing an identifier information of a machine transmitted through the topology network; An M2M signal traffic flow determining unit for determining whether a signal coming in via a session initiation protocol (SIP) and device information stored in a home policy server, a traffic policy DB unit, and a home subscriber server is M2M through the identifier, An SDN (Software Defined Network) based controller including an M2M signal traffic flow setting unit for classifying the virtualized IMS according to the virtualization IMS according to the virtualization IMS; And

And an IMS virtualization manager for managing an operating state of the virtualized virtual IMS.

Specifically, the M2M signal traffic policy DB unit identifies identifiers according to predetermined rules.

The M2M signal traffic flow determining unit determines whether the identifier is an M2M identifier or an M2M identifier.

In addition, the IMS virtualization manager comprises a configuration information unit and a monitoring unit of the IMS.

In addition, the SDN-based controller inserts or modifies traffic flow table information in a network equipment performing a virtualization function transmitted to the virtual IMS using a management protocol, so that a signal is transmitted.

In addition, the virtual IMS includes an M2M virtual IMS for processing an M2M signal and a general virtual IMS for processing a signal excluding an M2M signal.

As described above, the present invention has an effect of securing the safety and efficiency of the entire network for transmitting M2M control and data traffic.

In addition, the present invention has the effect of eliminating systematic hatching and excess density of the network caused by M2M.

Further, the present invention eliminates the expansion of the IMS network for processing the M2M signal, and also has the effect of cost reduction.

2 is a block diagram of an IMS platform management apparatus for M2M traffic according to an embodiment of the present invention.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the drawings, the same components are denoted by the same reference symbols whenever possible. In the following description, well-known functions or constructions are not described in detail since they would obscure the invention in unnecessary detail.

The present invention can distribute SMS (SMS) in the form of a signal coming in through SIP or a short message, and does not refer to distribution of voice and video data.

At this time, SMS is preferably mainly used as status information of the M2M device.

1 and 2 are block diagrams illustrating an IMS platform management apparatus for M2M traffic according to an embodiment of the present invention. The IMS platform management apparatus 10 for M2M traffic includes a SDN (Software Defined Network) And an IMS virtualization manager 200. The SDN-based controller 100 includes a network configuration information unit 110, an M2M signal traffic flow DB unit 120, an M2M signal traffic flow determination unit 130, And a flow setting unit 140.

In addition, the IMS virtualization manager 200 includes a configuration information unit 210 and a monitoring unit 220 of the IMS.

The IMS platform management apparatus 10 includes an M2M architecture 1,

The network configuration information unit 110 of the SDN-based control unit 100 has information on the M2M policy management information and the topology network.

In this case, the topology means a method of physically connecting the elements (link, node, etc.) of the computer network 400, and the data flow between the nodes on the network 400 determines the logical topology of the network 400.

The M2M signal traffic flow policy DB unit 120 stores the identifier information of the machine transmitted through the topology network. At this time, identifiers are divided into predetermined rules. Here, the rule may be set by various rules such as IP address, ID, device unique number, etc., and is not limited to any type of identifier.

The M2M signal traffic flow determining unit 130 determines whether the M2M signal is the M2M signal by matching the device information stored in the home subscriber server with the information of the SMS or the incoming signal through the SIP.

At this time, the home subscriber server is a centralized database for managing subscriber information. It is developed in the home location register (HLR) of mobile communication. It includes user registration / change management, authentication, authorization, location, session routing, And manages all subscriber information for session control.

Here, SIP is an application layer signaling protocol that specifies the procedures for intelligent terminals that want to communicate on the Internet to identify each other, find their location, and create / delete multimedia communication sessions with each other.

When the M2M signal traffic flow decision unit 130 can not determine whether the signal or SMS coming via the SIP (session initiation protocol) is M2M or not based on the device information stored in the home subscriber server, M2M < / RTI >

For example, since the M2M / IoT device may not have the device information in the home subscriber server, it can be determined as the identifier information stored in the M2M signal traffic flow policy DB unit 120. [

That is, the M2M signal traffic flow decision unit 130 can determine the M2M signal under the static condition when the dynamic condition is not satisfied.

The M2M signal traffic flow setting unit 140 classifies the virtualized IMS according to whether or not it is the M2M signal. At this time, the classified signal is transmitted to the virtual IMS through the router 500, and is divided into the general virtual IMS 310 or the M2M virtual IMS 320 and transmitted.

At this time, the M2M signal traffic flow setting unit 140 transfers the classified signal to the designated virtual IMS or controls the router 500.

In addition, the M2M signal traffic flow policy DB unit 120 has information on how the M2M traffic flow setting unit 140 sets the router 500 to control whether the router 500 is controlled or not.

That is, transferring to the designated virtual IMS 300 transfers the M2M signal to the M2M virtual IMS 320 and the non-M2M signal to the general virtual IMS 310. [

The virtual IMS 300 includes a general virtual IMS 310 and an M2M virtual IMS 320, and has a Call Session Control Function (CSCF) for performing call processing. It is an infrastructure system that performs basic functions for SIP-based multimedia session control, and is divided into Procxy-CSCF, interogating-CSCF, and Serving-CSCF according to their roles.

There is a home subscriber server in which profile information of the subscriber, authentication and location related data are stored, and an application server which holds the actual service logic and provides the service.

The IMS virtualization manager 200 grasps the operational state of the virtual IMS 300.

The configuration information section 210 of the IMS of the IMS virtualization manager 200 manages the topology of the IMS.

The monitoring unit 220 maintains and manages the operation and current state information of the virtualized IMS nodes, and is mainly related to performance and failure.

The IMS platform management method of the present invention stores corresponding information in the network configuration information unit and the M2M signal traffic flow policy DB. The M2M signal traffic flow determination mode matches the information stored in the M2M signal traffic flow policy DB, And controls the router 500 to transmit the signal determined by the M2M signal traffic flow determination module to the corresponding IMS.

Therefore, the present invention has the effect of securing the safety and efficiency of the entire network 400 for transmitting M2M control and data traffic, and has an effect of eliminating system hatching and excess densification of network caused by M2M.

The IMS platform management apparatus for M2M traffic is not limited to the configuration and operation of the embodiments described above. The above embodiments may be configured so that all or some of the embodiments may be selectively combined to make various modifications.
