A relay system according to an embodiment of the present invention will be schematically described with reference to FIG.

The relay system according to an embodiment includes a host unit (MHU) and a remote unit (RU). The host unit (MHU) is a unit that is connected between a base station that provides various wireless services and a plurality of remote units, and relays the communication so that communication using a plurality of services is possible.

The remote units (RUs) provide a service providing area (SA) for the user terminals (UM) to access the wireless communication service. The user terminals UM can use various kinds of wireless communication services by connecting to the remote unit RU.

Examples of services provided by the host unit (HMU) include CDMA 800, LTE700, LTE 1800, LTE 2600, WCDMA 2100, and WIFI.

The host unit according to one embodiment will be described with reference to FIGS. 2 and 3. FIG. FIG. 2 is a block diagram of a host unit according to an embodiment of the present invention, and FIG. 3 is a block diagram of a controller included in the host unit according to an embodiment.

The host unit 100 includes a service interface unit 110, a data processing unit 120, a frame processing unit 130, a frame transmission / reception unit 140, and a control unit 150.

The service interface unit 110 includes interfaces that can be accessed on a service-by-service basis in order to access various services provided by a base station (not shown).

The data processing unit 120 separates the data portion from the transmitted frame and converts the type of the service. Specifically, the data processor 120 separates a header or the like from data transmitted from a base station (not shown) or data transmitted from a remote unit to acquire information related to transmission included in the frame, As shown in FIG.

The frame processing unit 130 performs frame synchronization on data transmitted through the data processing unit 120 and data transmitted from the remote unit RU. Frame synchronization refers to the use of special bit combinations in the data connection protocol to indicate the beginning and end of a frame and to synchronize the transceivers in this manner.

The frame transmission / reception unit 140 transmits data framed in a specific service type to a remote unit (RU) or receives data transmitted from a remote unit (RU).

The control unit 150 receives data related to the type of RU services transmitted from the remote unit and stores the received data in an RU database (not shown) corresponding to the identification number of each remote unit. At the same time, each of the above- To control the operation. 3, the control unit 150 includes a service sensing unit 151, a service conversion unit 153, a service selection unit 155, and a monitoring unit 157. [

The service sensing unit 151 senses the type of data service received from the interface unit 110 described above. The service sensing unit 151 may receive a signal from the interface through which data is received and may detect the type of the service.

The service conversion unit 153 controls the data processing unit 120 to convert the service type of data received through the interface unit 110 into a specific service type. The service conversion unit 153 determines whether the type of data received through the interface unit 110 matches one of the types of services provided by the target remote unit. At this time, the type of the service provided by the remote unit is referred to from the RU database described above. If there is no service type of the received data in the services provided by the remote unit, the service conversion unit 153 can control to convert the service type of the transmitted data into one of the service types provided by the remote unit.

The monitoring unit 157 monitors the amount of traffic to be transmitted / received through each service interface unit 110.

The service selecting means 155 can determine the priority of selection among the service types to be converted, that is, the types of services to be converted by the data processing unit 120. For example, when it is determined that the amount of communication for a specific service type is relatively large by the monitoring means 157, the service conversion means 153 may avoid a specific service type among a plurality of conversion target services, Service type. In this case, it is also possible to set a threshold value of the communication amount for controlling to select another service type.

In addition, the control unit 150 checks the amount of traffic monitored by the monitoring unit 157, and increases the bandwidth allocated to the corresponding service type among the bandwidths of the transmission lines connected to the remote unit, It is also possible to prevent the user from stagnating.

On the other hand, when it is determined that there is no stored service type corresponding to a specific remote unit, or that there is no user terminal to be provided with a service in the service providing area provided by the remote unit, data is not converted or the data is transmitted to a remote unit It is also possible to control not to transmit.

A remote unit according to an embodiment will be described with reference to FIGS. 4 and 5. FIG. 4 is a block diagram of a remote unit according to an embodiment of the present invention, and FIG. 5 is a block diagram of an RU control unit included in a remote unit according to an embodiment of the present invention.

The remote unit 200b includes a short range communication RF unit 210b, an RU processing unit 220, an RU frame processing unit 230, an RU frame transmission / reception unit 240, and an RU control unit 250. [

The RU frame transmission / reception unit 240 transmits the frame synchronized data to the host unit (MHU) or receives the data transmitted from the host unit (MHU).

The RU frame processing unit 230 performs frame synchronization on the data transmitted through the RU processing unit 220 and the data transmitted from the host unit (MHU).

The RU processing unit 220 separates data through a specific service transmitted between the host unit (MHU) and the user terminal, and converts the separated data into a conversion target service type. That is, the RU processing unit 220 converts the service type of data to be transmitted into a target service type, similar to the data processing unit 120 of the host unit (MHU) described above.

The short-range communication RF unit 210b functions as a connection point for connecting a user terminal to a communication network, that is, a relay system, and is implemented using a short-range wireless communication technology standard such as WIFI or Bluetooth. As described above, in the embodiment of the present invention, the remote unit 200b communicates with the user terminal through the short-range wireless communication.

The RU control unit 250 includes an RU service sensing unit 251, an RU service type reporting unit 253 and an RU service selection unit 255 as shown in FIG.

The RU service detecting means 251 detects the service type of data transmitted from the user terminal. For example, the RU service detecting unit 251 may detect a service type of data by detecting a signal from a specific service interface through which data transmitted from a user terminal is received.

The RU service type reporting means 253 collects data on the service type detected by the RU service detecting means 251 and transmits it to the host unit (MHU). At this time, the type of service can be transmitted to the host unit (MHU) every time a signal from a specific user terminal is detected, and the signal from the user terminals detected every predetermined period is detected and transmitted to the host unit It is also possible to do.

Also, the RU service type reporting means 253 can detect the RU service type by the RU service detecting means 251 only when the type of service detected by the RU service detecting means 251 and the type of data transmitted from the host unit (MHU) It is also possible to transmit the service type to the host unit (MHU).

On the other hand, when the RU service detecting means 251 does not detect the user terminal, the RU service type reporting means 253 outputs a signal indicating that there is no user terminal in the service providing area or a signal indicating that there is no service type to be provided, Lt; / RTI > The host unit does not transmit data to the remote unit on the basis of such information, thereby preventing unnecessary waste of the transmission line.

The RU service conversion unit 255 controls the short range communication RF unit 210b so that the data received from the host unit (MHU) is transmitted to the user terminal by the short distance wireless communication method, or transmits the data transmitted from the user terminal And controls the RU processing unit 220 to convert the service signal into a service signal according to the service type. The RU service conversion unit 255 may control the RU processing unit 220 to frame the data transmitted from the user terminal together with the service ID related to the confirmed service type. This will be more clearly understood from the following description.

As described above, the remote unit 200b including the above-described configuration performs data transmission / reception through a short-range wireless communication method in relation to a user terminal in communication with a host unit (MHU) capable of multi-band mobile communication service For example, the following two schemes can be used.

In the first method, the remote unit 200b transmits the data received from the user terminal in the short-range wireless communication method to the service type (i.e., the used frequency band) of the user terminal detected (confirmed) by the RU controller 250 (Which may be performed by the RU processing unit 220) to a service signal according to the service protocol (for example, the service of the communication protocol) and transmits the service signal to the host unit (MHU) through the RU frame transceiver 240 . That is, the first method is a method of converting a service signal corresponding to the service type of the user terminal in the remote unit 200b itself, and then transmitting a frame related to the converted service signal to the host unit (MHU).

In the second method, a method of transmitting and receiving data only in two directions using a service-specific ID may be used between the remote unit 200b and the host unit (MHU). That is, when the service type of the user terminal is analyzed from the remote unit 200b and the corresponding service ID is transmitted to the host unit (MHU), the host unit (MHU) and the remote unit (200b) The data transmission and reception can be performed mutually based on the service ID indicating the service ID. In this case, the service ID indicating the service type of the user terminal may be framed and transmitted or received together with the data to be actually transmitted. In this case, the host unit (MHU) frames the service ID related to the service type of the user terminal, which is the destination of the data transfer, together with the transmission data and transmits the frame to the remote unit 200b, Only data can be separated and transmitted to the corresponding user terminal in the short-range wireless communication method. In the case of the data transmission in the opposite direction (i.e. remote- > host direction), the host unit (MHU) checks the corresponding service ID in the frame transmitted from the remote unit 200b, (Which can be performed by the service conversion means 153 of the host unit (MHU)) to the base station (not shown).
