Referring to FIG. 1, a cognitive radio communication system includes a plurality of terminals ue1 to ue6, cognitive radio cells (Mbs, Fbs1, and Fbs2), a carrier direct apparatus 100, and a cognitive radio database. DB).

In the embodiment, the plurality of terminals (ue1 ~ ue6) is described as a smart phone (smart phone), in addition to the smart phone, a notebook computer (notebook computer), digital broadcasting terminal, PDA (Personal Digital Assistants), PMP (Portable) It may be a mobile communication terminal including a multimedia player, a camera, navigation, a tablet computer, an e-book terminal, and the like, but is not limited thereto.

The plurality of terminals ue1 to ue6 may transmit data to the cognitive radio cells Mbs, Fbs1 and Fbs2, and may receive response data corresponding to the data.

That is, the plurality of terminals ue1 to ue6 may receive a communication service desired by a user from the recognition radio cells Mbs, Fbs1 and Fbs2 and the carrier integrated device 100, but is not limited thereto.

In an embodiment, the cognitive radio cells Mbs, Fbs1 and Fbs2 are shown as including one macro cell Mbs and two femtocells Fbs1 and Fbs2, but are not limited thereto.

In this case, each of the cognitive radio cells Mbs, Fbs1, and Fbs2 may transmit and receive data to a plurality of terminals ue1 to ue6 arranged in the set area.

Each of the cognitive radio cells (Mbs, Fbs1, Fbs2) may have a different shareable band obtained through access to a cognitive radio database (DB) or through spectrum sensing, and the carrier integrated device 100 may have a cognitive radio cell (Mbs, Fbs1). In this case, the licensed band and the shareable band allocated to Fbs2) can be used simultaneously.

Here, the licensed band is composed of a paired spectrum (paired spectrum) to utilize as a primary carrier (primary carrier) of the uplink (UL) and downlink (DL) by the frequency division duplexing (FDD) method, the shareable band is It is composed of an unpaired spectrum and is used as an auxiliary carrier of uplink (UL) or downlink (DL) in a time division duplexing (TDD) manner.

Here, the carrier integrated device 100 may allocate frequency resources utilized in the licensed band and the shareable band to each of the cognitive radio cells Mbs, Fbs1, and Fbs2.

That is, the carrier integrated device 100 assigns the sharable band obtained by connection or spectrum sensing to the licensed band and the cognitive radio database DB allocated to each of the cognitive radio cells Mbs, Fbs1, and Fbs2. According to the PRR and ARR, the critical quality of service level is determined according to the services provided by the cognitive radio cells (Mbs, Fbs1, Fbs2), the service requiring high reliability and priority is the frequency resource of the PRR rating, Services requiring relatively low reliability and priority provide communication services by utilizing frequency resources of ARR class.

Therefore, the data allocated to the frequency resource of the PRR class is composed mainly of a service requiring high QoS or QoE, and is real time or secure data, for example, voice call data, video call data, secure access data, control access data, and streaming data. It may be at least one of the above, and also includes VoIP, video-conference, streaming service and control signal, and the data allocated to the frequency resource of the ARR class is composed mainly of a service requiring low QoS or QoE, and is not real time or insecure. Data, such as text, FTP, and e-mail.

However, the frequency resources of the PRR class and the ARR class may provide a service having low QoS, QoE as the frequency resource of the PRR class according to the priority required by the user, and high QoS, It can provide a service with QoE.

In this case, the carrier direct apparatus 100 uses the cognitive radio database (DB) or spectrum sensing to determine frequency resources whose frequency bandwidth is variable and discontinuous depending on the position and time of the cognitive radio cells Mbs, Fbs1 and Fbs2. By classifying according to the present invention, frequency resources of the sharable band can be secured.

The variable for the frequency quality measurement may be determined by at least one of a signal-to-noise ratio, a frequency bandwidth, and a channel state of a frequency allocated to each of the licensed band and the shareable band, but is not limited thereto.

In addition, the grade management unit 110 is a licensed band allocated to the cognitive radio cells (Mbs, Fbs1, Fbs2) and the shareable band obtained by cognitive radio database (DB) or spectrum sensing according to the frequency quality of Primary Radio Resource (PRR) The class and the shareable band can be managed by classifying them into ARR (Auxiliary Radio Resource) class.

That is, the grade management unit 110 grades the licensed band as the PRR grade and the shareable band as the ARR grade, or when the reference band set among the licensed band and the shareable band is satisfied, the graded PRR grade. A band that does not satisfy the reference band may be rated as the ARR band.

In an embodiment, the rating manager 110 selects a band satisfying or not satisfying the reference band among the licensed band and the shareable band and classifying the PRR level and the ARR level. There is no limit.

The grade management unit 110 determines the licensed band when the frequency quality of the licensed band is higher than the frequency quality of the shareable band based on the licensed band and the shareable band allocated to the cognitive radio cell Mbs. The PRR class and the shareable band are graded to the ARR class, and if the frequency quality of the shareable band is higher than the frequency quality of the licensed band, the shareable band is the PRR band and the licensed band the ARR band. The PRR grade and the ARR grade may be changed at a predetermined time or in real time, without being limited thereto.

As described above, the class manager 110 may use the licensed band as the set reference band, and may change the reference band to another band, without being limited thereto.

Here, the Primary Radio Resource (PRR) rating is a rating for providing the first communication service requiring a high level of service reliability and user demand, security, and real-time service, and the ARR (Auxiliary Radio Resource) rating is The service reliability and the user's request priority is low, security is required, and a class for providing the second communication service requiring non-real-time service.

In other words, the PRR class provides higher network performance, quality of service (QoS), and quality of experience (QoE) than the ARR class.

In addition, the class manager 110 may determine a detailed transmission method of the RF, PHY, MAC, and RLC layers according to the frequency characteristics and the environment obtained in the PRR class and the ARR class.

Here, the real time or the security data may include at least one of voice call data, video call data, secure access data, control access data, and streaming data, and the non-real time or non-secure data may include text data and email. It may include at least one of the data.

In this case, the non-real time or the non-secure data has a lower priority than the real time or the secure data, and the present invention is not limited thereto.

The service provider 130 reserves the frequency division duplexing (FDD) based on the frequency division duplexing (FDD) when the arbitrary data requests the first communication quality of service according to the determination result of the decision unit 120. Provides a communication service to a cognitive radio cell (Mbs), and uses a time division duplexing (TDD) based contention scheme with the ARR class when the arbitrary data requires the second communication quality of service. To provide a communication service to a cognitive radio cell (Mbs).

The carrier direct apparatus according to the embodiment may provide a communication service based on a predetermined class of arbitrary data provided from a cognitive radio cell or a user terminal, and thus, may improve the efficiency of allocated frequency resources. According to the frequency resource class, an appropriate detailed transmission method may be determined in the RF, PHY, MAC, and RLC layers to further increase frequency resource utilization efficiency.
