In the modern society, the field of mobile and broadcasting communication services is expanded and reproduced in all fields of society, including transportation, medical care and everyday life of the people. From the small home network that forms the mobile ecosystem to the large-scale U-city category, the demand for frequency use in each sector is rapidly expanding into a new service area with the convergence with other industries. Especially, all objects around us are connected through network, so that it is possible to acquire and transmit necessary information anytime and anywhere, and M2M (Machine to Machine) service, which enables various services to be provided and used, It is becoming a major issue.

In order to meet the exponential increase in frequency demand, the development of technology to maximize the use efficiency of radio waves to cope with the interference and sharing problem between homogeneous and heterogeneous wireless communication services and to cope with the surge in frequency demand is becoming more important than ever. Particularly, there is a need for advanced frequency-efficient utilization technology and new frequency resources due to a surge of radio communication traffic and depletion of frequency resources. Therefore, there is a need for effective redistribution of spectrum, frequency efficiency technology and service model for fair use without mutual interference, A study of the model is needed. Furthermore, interference between broadcast and wireless communication services for various purposes in licensed and license-exempt bands is intensifying, and an integrated wireless communication processing processor is needed that can efficiently and actively cope with interference between homogeneous or heterogeneous devices .

The mobile communication infrastructure technology for supporting M2M service is called MTC (Machine Type) in 3rd Generation Partnership Project (3GPP) by referring to the "IT Standardization Trend of Communication Type Scenario Communications. Recently, in 3GPP SA1 and SA2, service standards based on MTC device and MTC server communication model and technical standard about network structure for M2M support are being promoted. In addition, the "MTC performance improvement study" published in the Technical Report 22.888 published by the 3GPP SA1 defines communication scenarios and usage forms between the MTC devices as shown in FIGS. 1A to 1C.

Figure 1a shows a direct communication scenario and usage pattern between MTC devices. Referring to FIG. 1A, it is assumed that the MTC device establishes direct communication with other MTC devices in the 3GPP network, and that it knows the IP address or MSISDN of the remote MTC device. That is, if the MTC device is assigned a fixed IPv6 address and knows the address of the remote MTC device (IPv6 based communication) and the MTC device knows the MSISDN of the remote MTC device (eg, MTC device Direct communication is possible.

1B shows an MTC device communication scenario and a usage form via an MTC server. Referring to FIG. 1B, all data transmission is performed through the MTC server, and the MTC device need not know the identifier for routing of each device. At this time, the MTC server provides a function of searching for an identifier (IP address, MSISDN, application layer identifier, etc.) of the remote MTC device, and the MTC device executes the connection setting process with the MTC server and transmits data to the server with the remote device identifier .

FIG. 1C illustrates an MTC device communication scenario and a usage form through a 'name resolution function' implemented in a network / MTC server. Referring to FIG. 1C, this scenario supports communication between MTC devices through a network or name resolution function in the MTC server. The name resolution function is defined as a function within the DNS or MTC server. This scenario is used when the identifier information of the remote MTC device is known as a non-routable identifier (MSISDN, SIP URI, etc.).

The communication scenarios and usage patterns between the MTC devices described with reference to FIGS. 1A to 1C are currently 45% completed. In the 59th meeting of the 3GPP SA1 held in July 2012, the MTC device communication scenario contribution is not submitted, It is in a state that star use form is insufficient. In addition, considering only the utilization method for the MTC radio device in the cellular band, there is a problem that interference countermeasures for smooth coexistence of homogeneous and heterogeneous wireless communication devices existing in various frequency bands, and smooth service operation processing process are not proposed.

In addition, the interworking scenario of the present invention forms a connection interface between a core network and an MTC server via a wireless access network for various wireless communication services requested by a user of an MTC wireless device having a dual band triple mode function. In addition, the wireless access network is composed of TV white space, TVBD, LTE base station and PAN coordinator for cellular mobile communication service.

The MTC server shares the location information beam forming management DB, the interference countermeasure management management DB, and the TVWS geo-location DB information, and integrally manages the information. To this end, the MTC server shares the service user information requesting the dual band and triple mode service provided by the MTC provider. It also manages channel usage status, available channel information, and service user information transmitted from each DB. At this time, security is the responsibility of the MTC service provider. It also has a security interface (general security algorithm) processing block between heterogeneous services and uses a web-based, universal common interface access method for compliance with heterogeneous network interoperability.

The MTC server is composed of a wireless access network and a core network connecting a MTC service provider and a dual band triple mode MTC wireless device (hereinafter, referred to as an 'MTC wireless device') and a DB and a wired / Perform management tasks. To this end, the MTC server performs user information management for the MTC wireless device, persistent management of each DB delivery information, selection and update of service type, area, and interference correspondence process according to the communication environment.

The MTC service provider transmits the pre-registered MTC radio device user information and the requested service information to the MTC server. At this time, the MTC server selectively applies an appropriate service to the MTC service user using the MTC wireless device user information transmitted from the MTC service provider and the wireless communication environment information transmitted from each DB, and applies the overall management and the interference response process. For this purpose, the MCT server sets the TVWS, the allowable channel and the bandwidth size covering the cellular band, and the service availability time according to the requested service. In addition, by using the information transmitted from each DB, the MTC wireless device finally approves the frequency band, the channel information, and the service type that can be used by the MTC wireless device, and updates the individual information data for a predetermined period.

On the other hand, in the MTC server, a separate processing block for performing authentication, registration, and management for the user ID of the MTC wireless device for service user management is disposed.
