Description

  The present invention relates to a wireless communication system.

  Conventionally, in order to improve society and daily life, it is expected that information communication application services will be advanced and diversified using information communication technology including wireless communication technology. Along with this, traffic patterns are becoming wider from M2M / IoT (Machine to Machine / Internet of Things) communication with a small amount of information to be transmitted to rich content with a large amount of information such as video streaming. Today, fourth generation mobile communication systems represented by LTE (Long Term Evolution) (registered trademark, the same applies hereinafter) and LTE-Advanced are used. However, in order to efficiently support traffic patterns that vary greatly depending on time, place, application, and device type, next-generation fifth-generation (5G) next-generation mobile communication systems are being studied.

  It is difficult to accommodate various traffic patterns with a single radio access technology (RAT). For example, mobile communication systems such as LTE and LTE-Advanced are suitable for applications in which a person carries a smartphone or the like to perform web browsing or streaming video viewing. However, in applications where metering information is collected by attaching to an electric meter or water meter, it is necessary to replace the battery of the wireless communication terminal with large power consumption, which is not appropriate in terms of the terminal capacity and cost. Problems arise. Therefore, wireless LAN (Local Area Network) known for new-RAT and Wi-Fi (Wireless Fidelity) (registered trademark, the same shall apply hereinafter) being studied for 5G, WiMAX (Worldwide Interoperability for Microwave Access) (Registration) BWA (Broadband Wireless Access), which is known as a trademark, and the like, other wireless networks known as Wi-Gig (Wireless Gigabit), etc., Bluetooth (registered trademark, the same applies hereinafter) and Zigbee (also known as short-range wireless) Multi-RAT configurations (also referred to as heterogeneous networks) that combine various radio systems according to application purposes such as registered trademarks (hereinafter the same) are being studied.

  As a technique for actually linking a plurality of RATs, there are multi-connection and ANDSF (Access Network Discovery and Selection Function). ANDSF is an established specification of 3GPP (Third Generation Partnership Project). Either technique can be applied to a smartphone or the like provided with LTE as the first RAT and Wi-Fi as the second RAT. Multi-connection is the terminal side initiative by observing the reception status of radio waves at the terminal, and ANDSF is the network side initiative by the network side providing the RAT selection connection policy to the terminal based on the terminal location information etc. RAT suitable for the situation can be selected.

FIG. 1 is a configuration diagram showing a system configuration of a wireless communication system 100 according to the present invention. The wireless communication system 100 includes a plurality of base station devices 10-1 to 10-4, a wireless control unit 20, a server-side RAT management unit 30, and a wireless communication terminal 40. Each base station apparatus 10 and the wireless communication terminal 40 perform wireless communication by a predetermined RAT. In this embodiment, a case where there are four base station apparatuses 10 will be described as an example. However, the number of base station apparatuses 10 may be three or less, or may be five or more.

  In the following description, the RAT used between the base station apparatus 10-1 and the radio communication terminal 40 is described as RAT1, and the RAT used between the base station apparatus 10-2 and the radio communication terminal 40 is RAT2. RAT used between the base station apparatus 10-3 and the radio communication terminal 40 is described as RAT3, and RAT used between the base station apparatus 10-4 and the radio communication terminal 40 is described as RAT4. .

  Any radio access technology may be used for the RAT 1 as long as it has wide-area connectivity, can perform bidirectional communication, can be provided at low cost, and has low power consumption. Here, wide area connectivity means that each RAT 2-4 can be activated / managed and has connectivity equivalent to or higher than any RAT 2-4 that can be selected, and can cover a wide range. . In addition, bidirectional communication means that various information can be exchanged between the server-side RAT management unit 30 and the wireless communication terminal 40 in order to activate / manage the RATs 2 to 4. Low cost also means that communication chips / modules and communication charges can be used very inexpensively. In addition, low power consumption means that the wireless communication system has extremely low power consumption in order to cope with an IoT service that operates on a battery for a long time. RAT1 is a cellular system (2G-4G), for example. RAT1 is an LP-WAN (Low-Power Wide-Area Network) for M2M such as LTE-MTC (LTE-Machine Type Communications), SigFox (registered trademark, the same applies below) and LoRa (registered trademark, the same applies below). Or the like. RAT1 corresponds to the first RAT.

  RATs 2 to 4 are cellular systems, microwave radios (for example, Wi-Fi, Zigbee (registered trademark, the same applies below), Bluetooth (registered trademark, the same applies below), etc.), millimeter wave band radios (eg, WIGIG (registered trademark)). Sub-GHz band wireless (for example, Wi-SUN (Wireless Smart Utility Network) (registered trademark, the same applies below), Z-wave (registered trademark, the same applies below), Zigbee, Wi-HaLow (registered trademark) , Etc.)) or software defined radio. RATs 2 to 4 correspond to RAT candidates for determining the second RAT. As the second RAT, any radio access technology may be used as long as the radio access technology satisfies at least low latency or large capacity.

  The base station apparatus 10 performs wireless communication with the wireless communication terminal 40 using a predetermined RAT. Moreover, the base station apparatuses 10-2 to 10-4 relay data between the terminal application and the server application. Base station apparatuses 10-1 to 10-4 may be provided in different places, some base station apparatuses 10 may be provided in different places, or all base station apparatuses 10 may be provided in the same place. May be provided. In general, when the RAT such as LTE or Wi-Fi is different, the radio wave arrival distance and the like are also different. Base station apparatus 10-1 is connected in a state where it can communicate with radio control unit 20. The base station devices 10-2 to 10-4 communicate with the server-side RAT management unit 30 and the server application via the RAT networks 50-1 to 50-3. Since each base station apparatus 10 is connected through the server-side RAT management unit 30, the operators may be different from each other, and license bands and unlicensed bands may be mixed.

The radio control unit 20 is provided on the upstream side of the base station device 10-1, and performs network connection to the Internet or the like such as terminal identification and terminal authentication of the radio communication terminal 40. The radio control unit 20 has a function of AAA (Authentication, Authorization, and Accounting).
The server-side RAT management unit 30 has a plurality of interfaces for communicating with each base station apparatus 10. The server-side RAT management unit 30 selects a plurality of RAT candidates that can be provided by the server side based on the communication requirements specified or requested by the server application or the communication requirements acquired from the U / I 60 and the performance information of the wireless communication terminal 40. A second RAT is determined from the inside. Here, the performance information of the wireless communication terminal 40 represents information related to the hardware performance of the wireless communication terminal 40. The performance information is information such as RAT that the wireless communication terminal 40 has, for example. And the server side RAT management part 30 is the base station apparatus 10 which has the determined 2nd RAT.
The switching, control and setting for using the second RAT are performed. Here, the switching in the server-side RAT management unit 30 represents switching the RAT for performing data transmission / reception between the server application and the terminal application to the second RAT. The setting in the server-side RAT management unit 30 indicates that the base station apparatus 10 is set to use the second RAT in order to transmit and receive data between the server application and the terminal application.

  Further, the server-side RAT management unit 30 constructs the second RAT using the software radio technology when the software radio technology is installed in the base station apparatus 10 and / or the radio communication terminal 40 or both.

As described above, the server-side RAT management unit 30 selects the optimum second RAT from the RAT candidates based on the communication requirements acquired from the server application or the U / I 60 and the performance information of the wireless communication terminal 40. Then, processing such as selection, switching, construction, control and setting of the second RAT is performed. The server-side RAT management unit 30 notifies the radio communication terminal 40 of information necessary for using the second RAT via the radio control unit 20 and the C plane or U plane of the base station device 10-1. The server-side RAT management unit 30 constructs a new second RAT in the base station apparatus 10 so that the second RAT can be used to transmit and receive data between the server application and the terminal application.

  As described above, the base station apparatus 10-1 of RAT1 and the base station apparatus 10 having the second RAT are not necessarily in the same place. Therefore, it is necessary to perform matching between the radio communication terminal 40 and the base station apparatus 10 in the second RAT to be determined in consideration of the installation location of the base station apparatus 10 having the second RAT. For this purpose, it is generally desirable that the coverage of the base station apparatus 10-1 for RAT1 includes the coverage of the base station apparatus 10 for other RAT candidates. Conversely, the base station apparatus 10 having the second RAT only needs to be installed in the vicinity of a place where there is a communication requirement from the wireless communication terminal 40.

The terminal-side RAT management unit 41 (second management device) performs selection, switching, construction, control, and setting of the second RAT according to the notification from the server-side RAT management unit 30. Here, switching in the terminal-side RAT management unit 41 represents switching the RAT for performing data transmission / reception between the server application and the terminal application to the second RAT. The setting in the terminal-side RAT management unit 41 indicates that the communication unit 42 is set to use the second RAT in order to transmit and receive data between the server application and the terminal application. In the terminal-side RAT management unit 41, the second RAT is newly built in the communication unit 42 so that the second RAT can be used to transmit and receive data between the server application and the terminal application. Represents what to do. The communication unit 42 communicates with the base station device 10 using a predetermined RAT. For example, the communication unit 42-1 performs communication with the base station apparatus 10-1 using RAT1. In the present embodiment, the wireless communication terminal 40 includes four communication units 42. However, the communication units 42 are provided in a number corresponding to the performance of the wireless communication terminal 40. That is, if the wireless communication terminal 40 can use two RATs, two communication units 42 are provided.

FIG. 6 is a sequence diagram showing a processing flow of the wireless communication system 100.
The acquisition unit 301 acquires communication requirements from the server application or the U / I 60 (step S101). The acquisition unit 301 outputs the acquired communication requirements to the RAT management unit 305. Thereafter, when the wireless communication terminal 40 is activated, the terminal-side RAT management unit 41 starts wireless connection (step S102). At this time, the terminal-side RAT management unit 41 searches for the base station apparatus 10 having RAT1 (step S103). Here, it is assumed that the base station apparatus 10 having RAT1 is the base station apparatus 10-1. The terminal-side RAT management unit 41 is connected to the base station apparatus 10-1 having RAT1 through the communication control unit 423-1 and the wireless communication unit 422-1 (step S104).

  When the base station apparatus 10-1 and the radio communication terminal 40 are connected, the radio control unit 20 requests an ID from the radio communication terminal 40 for terminal identification and terminal authentication via the base station apparatus 10-1. (Step S105). The wireless communication unit 422-1 receives the request transmitted from the wireless control unit 20. The wireless communication unit 422-1 outputs the received request to the communication control unit 423-1. The communication control unit 423-1 acquires the ID from the identification information storage unit 421 in response to the request output from the wireless communication unit 422-1. The communication control unit 423-1 controls the wireless communication unit 422-1 to transmit the ID to the wireless control unit 20 (step S106).

  The wireless control unit 20 receives the ID transmitted from the wireless communication terminal 40. The wireless control unit 20 identifies and authenticates the wireless communication terminal 40 based on the received ID (step S107). When authentication is performed by the wireless control unit 20, the server-side RAT management unit 30 and the terminal-side RAT management unit 41 are connected (step S108). Next, the terminal-side RAT management unit 41 requests the ID and the hardware performance information of the radio communication terminal 40 from the radio communication terminal 40 via the radio control unit 20 and the base station device 10-1 (step S109). ).

  The wireless communication unit 422-1 receives the request transmitted from the wireless control unit 20. The wireless communication unit 422-1 outputs the received request to the communication control unit 423-1. The communication control unit 423-1 acquires the ID from the identification information storage unit 421 and the performance information from the performance information storage unit 43 in response to the request output from the wireless communication unit 422-1. The communication control unit 423-1 controls the wireless communication unit 422-1 to transmit the ID and performance information to the wireless control unit 20 (step S110). The communication unit 302-1 receives the ID and performance information transmitted from the wireless communication terminal 40.

  The RAT management unit 305 performs switching, control, and setting for making the determined second RAT available to the base station apparatus 10-2 (step S112). For example, the RAT management unit 305 performs switching, control, and setting by transmitting a notification including an instruction to perform an operation for enabling the second RAT to the base station device 10-2. The base station device 10-2 receives the notification transmitted from the server-side RAT management unit 30. The base station device 10-2 performs an operation for making the second RAT available based on the received notification. For example, when the notification includes the fact that a second RAT is newly constructed, the base station device 10-2 newly constructs a second RAT according to the received notification.

  The wireless communication unit 422-1 receives the notification transmitted from the server side RAT management unit 30. The wireless communication unit 422-1 outputs the received notification to the terminal-side RAT management unit 41 via the communication control unit 423-1. The terminal-side RAT management unit 41 performs switching, control, and setting so that the second RAT can be used based on the notification output from the communication control unit 423-1 (step S113). Thereby, the radio | wireless communication terminal 40 and the base station apparatus 10-2 are connected by 2nd RAT. Thereafter, data transmission / reception between the terminal application and the server application is performed via the base station apparatus 10-2 (step S114). If the wireless communication state is deteriorated or the communication requirement is changed, the processes after step S111 are repeatedly executed.

An application example of the present invention will be described.

Thereby, the connection in Zigbee with the base station apparatus 10 which can use Zigbee, and the radio | wireless communication terminal 40 is established. Thereby, transmission / reception of data between applications is started using Zigbee.

  The wireless communication terminal 40 is an AV device, the wireless communication terminal 40 can use LTE-MTC, Wi-Fi, and Wi-Gig, and “AV device (Wi-Fi or Wi-Gig)” is given as a communication requirement. Consider the case. First, the radio communication terminal 40 connects to the base station apparatus 10-1 using LTE-MTC. When the server-side RAT management unit 30 is connected to the base station device 10-1, the given communication requirements and the performance information of the wireless communication terminal 40 (for example, LTE-MTC, Wi-Fi, and Wi-Gig The base station apparatus 10 that can use either Wi-Fi or Wi-Gig is searched, and the optimal base station apparatus 10 is determined in each base station apparatus 10. For example, the server-side RAT management unit 30 determines which of Wi-Fi and Wi-Gig is used as the second RAT based on the effective throughput that can be realized by each base station apparatus 10. In accordance with this determination, the server-side RAT management unit 30 selects the optimum base station apparatus 10. Then, the server-side RAT management unit 30 transmits information necessary for connection to the searched base station device 10 (for example, information such as SSID and IP address designation) via the radio control unit 20 and the base station device 10-1. To notify. Thereafter, the server-side RAT management unit 30 and the wireless communication terminal 40 perform settings necessary for connection. Thereby, the base station apparatus 10 that can use the determined second RAT and the wireless communication terminal 40 establish a connection in the second RAT. Thereby, transmission / reception of data between applications is started using the second RAT.

  As a method of determining the base station device 10 to which the wireless communication terminal 40 should be connected, the server-side RAT management unit 30 can be used based on position information obtained using GPS (Global Positioning System) or the like. May be searched with reference to a list of wireless access technologies (or wireless access technology providers), or the wireless communication terminal 40 may directly search the base station device 10 and select one with strong radio field strength. It may be determined by combining both.

(Application Example 2: When searching for an available RAT1 base station apparatus 10 and further searching for and connecting to a provider providing a radio access technology suitable for communication requirements)
As a service on the server (base station) side, the operator 1 is “LTE” + “Wi-Fi” + “Wi-SUN”, and the operator 2 is “Wi-MAX” + “Wi-Gig” + “Zigbee”. It is assumed that the business operator 3 provides “LoRa” + “Wi-Fi” and the business operator 4 provides the server-side RAT management unit 30 on the cloud.

  The wireless communication terminal 40 that can use “LTE” + “Wi-Fi” searches for a base station device 10 that can use LTE and connects to the base station device 10 of the operator 1. The server-side RAT management unit 30 selects the Wi-Fi of the business operator 1 and performs Wi-Fi connection for transmitting and receiving data between applications by the same method as in Application Example 1.

  The wireless communication terminal 40 that can use “LoRa” + “Wi-Fi” searches for a base station device 10 that can use LoRa, and connects to the base station device 10 of the operator 3. The server-side RAT management unit 30 selects the Wi-Fi of the business operator 1 or the business operator 3 based on the radio wave environment or the usage fee and transmits / receives data between applications in the same manner as in the first application example. Wi-Fi connection.

  The wireless communication terminal 40 that can use “LTE” + “920 MHz band software defined radio” searches for a base station device 10 that can use LTE and connects to the base station device 10 of the operator 1. Further, the server-side RAT management unit 30 searches for a 920 MHz band service that can be used in the area of the base station device 10 of the operator 1, and when it is determined that the Wi-SUN provided by the operator 1 can be used, The communication terminal 40 is notified. Then, the wireless communication terminal 40 is configured to be able to use Wi-SUN in the communication unit 42 of its own apparatus, and performs Wi-SUN connection for transmitting and receiving data between applications in the same manner as in the first embodiment. .

  The wireless communication terminal 40 that can use “LTE” + “920 MHz band software defined radio” searches for a base station device 10 that can use LTE and connects to the base station device 10 of the operator 1. Furthermore, when the server-side RAT management unit 30 searches for a base station device 10 that can use the available 920 MHz band software radio, and finds the Zigbee base station device 10 of the operator 2, the radio communication terminal 40 Notify Then, the wireless communication terminal 40 is configured to be able to use Zigbee in the communication unit 42 of its own device, and performs Zigbee connection for transmitting and receiving data between applications in the same manner as in the first embodiment.

According to the wireless communication system 100 configured as described above, it is possible to satisfy various service application requirements. Hereinafter, this effect will be described in detail.
In the wireless communication system 100, the main route (RAT1) is provided with a minimum necessary function for securing network connection to the Internet or the like such as terminal identification and terminal authentication. In other words, the main route does not necessarily have to satisfy severe communication quality performance such as low latency and large capacity of communication. This is because the characteristics of the radio access technology such as low latency and large capacity may be selected as the second RAT or newly constructed. Therefore, the RAT 1 is generally applicable to a wireless communication system such as an LPWAN having low communication performance, which is generally low speed and inexpensive. Therefore, a wireless communication system that satisfies various service application requirements can be constructed by utilizing the wireless communication terminal 40 for activation trigger and operation management.

  According to the present invention, it is possible to select an optimal RAT from among three or more RATs that can be used based on communication requirements required by the server application. This is different from the prior art which assumed only simple selection control such as selecting a usable RAT by simply comparing radio conditions of two RATs of LTE and Wi-Fi.

  According to the present invention, in determining the RAT for actually performing data communication between applications, the wide area wireless system can be used as the first wireless communication method, and activation and operation management when the wireless communication terminal 40 is installed can be performed. With this configuration, it is possible to provide a dynamic and highly flexible wireless access environment in which a suitable wireless communication method can be individually customized according to advanced and diverse requirements of the application. This point is different from the conventional technique aiming to selectively use from a plurality of limited RATs that can be used without having an independent individual RAT for start-up operation.

  According to the present invention, a base station apparatus that uses a wide-area wireless system such as a cellular system provided by RAT1 and functions such as terminal identification / authentication possessed by the system and a second RAT that actually performs data communication between applications 10 through the server-side RAT management unit 30 and the terminal-side RAT management unit 41, it is possible to perform loosely coupled and cooperative connections between a plurality of RATs with high expandability and flexibility. As a result, the second RAT can be freely installed and constructed by a business operator who recognizes that the second RAT is necessary based on business or the like. That is, in general, the telecommunications carrier that provides RAT1 may provide the second RAT, or another carrier may provide the second RAT. The second RAT may be provided by a communication carrier using a license band, or another carrier may use a license-free band. In this way, it is possible to construct a wireless network with a high degree of freedom by combining these networks without distinguishing between public networks and private networks.

  According to the present invention, as RAT1, in addition to cellular systems (2G to 4G), LTE-MTC, LPWAN for M2M such as SigFox and LoRa, and the like can be applied. Thereby, it can utilize at low cost for M2M / IoT. Such low cost use has a significant business impact in applications for M2M / IoT. Since the present invention is configured to combine a plurality of RATs on the terminal side, a method for realizing a wireless communication module at a lower cost with the spread of LTE-MTC and LPWAN with low hardware and operation costs of the wireless communication terminal 40 is provided. Can be provided.

  According to the present invention, the RAT 1 can be utilized as a network configuration / construction start trigger / management means such as device identification (ID) / authentication / control. That is, it is possible to provide a wireless tag usage method for tagging communication requirements of the wireless access technology used in actual data communication and other information related to the wireless communication terminal 40 based on the terminal identification symbol system possessed by the RAT1. In the case of a general wireless tag, a tag reader is separately required. However, if a wide area wireless communication system is used as the RAT 1, no additional equipment investment on the server side is required. Further, by using the identification symbol of RAT1 whose ID and communication address are not affected by the installation location, the connected base station, etc., the same usability can be realized without being aware of the installation location within the RAT1 cover area.

According to the present invention, not only selection and new construction of a radio access technology based on communication requirements, but also a usage range, usage (communication quality including a communication band), service provision period based on a contract status with a user. Etc. can be managed on the cloud side in association with identification symbol (subscriber) information provided by RAT1. This facilitates management of billing and the like related to provision of the second RAT.
According to the present invention, it is possible to select and use a suitable second radio access technology from among a plurality of existing radio access technologies provided in the base station device 10 and the radio communication terminal 40 as the second RAT. In addition, according to the present invention, it is possible to construct and control a new RAT according to wireless communication requirements by using it together with software radio technology as the second RAT.

  According to the present invention, it is possible to simultaneously provide connectivity of not only RAT2 but also RAT3 and RAT4 between the server-side RAT management unit 30 and the terminal-side RAT management unit 41 for the same application pair. become. In other words, a plurality of RAT connections can be simultaneously provided for a specific application pair (providing a multipath TCP service), or a plurality of RAT connections can be physically used between Multi-RAT management units. The application pair can be configured to virtually provide a single RAT connection.

  According to the present invention, there is provided a wireless system architecture for configuring various Multi-RAT environments in a sustainable manner. In other words, since the RAT itself has a control plane in 802.11 wireless LAN, etc., backward compatibility with old standards such as 802.11b and 11a is ensured in the same frequency band of 2.4 GHz band and 5 GHz band. Therefore, problems such as a reduction in throughput have occurred. However, if the present invention is used, forward / backward compatibility such as between different RATs or in-RAT versions can be secured by using RAT1, so that the second RAT has a simple C / U that satisfies the necessary requirements. A plane configuration can be dynamically constructed and provided on demand.

  According to the present invention, RAT management units (server-side RAT management unit 30 and terminal-side RAT management unit 41) for managing a plurality of RATs are provided on both the server side and the radio communication terminal 40 side, and outside each RAT. Therefore, the RAT manager function can be flexibly arranged. That is, the wireless communication terminal 40 can be arbitrarily arranged on a cloud that can be connected to the Internet or the like, and it is easy for a provider different from each RAT provider to provide the service. In addition, a configuration in which a plurality of different operators each have a RAT management unit is also possible. Also for the terminal-side RAT management unit 41, a plurality of RAT communication modules are separately prepared on the wireless communication terminal 40 side, and they are combined and connected by an external wiring or the like, thereby facilitating flexible selection and mounting of the RAT.

  According to the present invention, even when the optimum RAT for data communication between applications cannot be selected / constructed, or even when the communication state of the second RAT is deteriorated or disconnected, the situation via the RAT 1 Can be grasped. Therefore, it is possible to notify the connection status of the second RAT to the application on the server side or the terminal side. Even in a state where the second RAT is not connected, both RAT management units can grasp through RAT1 that a connection request for the second RAT exists in the area. For this reason, it is possible to easily cope with installation of the base station apparatus 10 that can newly use the second RAT according to needs.

  According to the present invention, the wireless communication terminal 40 itself can have communication requirements such as a terminal position and wireless communication quality required by the application, or can be directly registered via a web interface or the like for Internet connection. You can also. M2M / IoT terminals have poor input / output interfaces (in many cases they do not have a display or keyboard), so there are many users who want to make online settings directly, but these requests can be easily handled. Can do.

  According to the present invention, as RAT1, not only a cellular system mechanism using a SIM card but also an LTE-MTC that can implement an inexpensive radio communication terminal 40 using an embedded SIM or a soft SIM, or a SIM is different. It is also possible to apply LPWAN that performs terminal identification and authentication using a mechanism. Economically and rationally by applying an architecture that flexibly combines the hardware resources for RAT1 having the minimum wide area wireless communication function and the hardware resources for the second RAT necessary and sufficient according to the application. Therefore, it can be applied to a wide range of applications.

  According to the present invention, when a terminal is installed and activated, a procedure for selecting a RAT suitable for an application after first confirming the validity of the terminal with reference to RAT1 is provided. For application data communication, it is generally assumed that the base station apparatus 10 having the same RAT function as the RAT of the wireless communication terminal 40 is installed in the same area when the terminal is installed. Although it is necessary to have a common setting value for the communication unit / control unit on the server side and the terminal side, in the present invention, it is not necessary to assume the existence of such a base station. That is, the connection setting information of the second RAT used for application data communication can be exchanged via the RAT 1 after the selection of the second RAT is confirmed. Even when there are a plurality of providers providing base station apparatuses 10 that can use the same second RAT, these can be easily switched according to economic conditions such as price, and the second Even when the base station apparatus 10 providing the RAT is not in the same area as the wireless communication terminal 40, the situation can be notified to the server side via the RAT1.

  According to the present invention, it is possible to design a radio communication system flexibly and freely as the second RAT by utilizing software radio technology or the like. In M2M / IoT systems including those for industrial use, various demands such as high speed, large capacity, low delay, multi-terminal accommodation, low power consumption, and low cost are assumed. However, wireless communication systems and modules provided in the market may not always meet the needs. Wireless communication system that includes not only the U plane but also the C plane in order to customize the wireless communication to meet the needs such as specific communication delay and the number of terminals accommodated in limited areas such as factories. Customization is also considered effective. If this invention is used, the radio | wireless communication system specialized for a specific area and the use can be dynamically customized on demand.

  According to the present invention, on the basis of the existing wireless communication standard, under the condition of satisfying the mandatory standard of frequency use specified by the Ordinance of the Law such as the Radio Law, it is possible to intentionally implement partly different from the existing wireless communication standard. It is also possible to improve security. For example, by using a scramble code used between the base station and the terminal or a code replacement pattern that is intentionally different from the standard, wireless communication with advanced security that is difficult to wiretap with normal standard-compliant wireless devices Can also be realized locally.

  According to the present invention, the RAT 1 can be used not only when the wireless communication terminal is activated and installed, but also for subsequent maintenance operations. For example, the connection state of the second RAT can be controlled in accordance with the contract period with the user. In addition, when the communication state of the second RAT changes, dynamic switching / change to another RAT can be easily performed. Even when wireless communication requirements such as wireless communication quality required by an application change, it is possible to easily perform dynamic switching / change to another RAT by dynamically rewriting it.
