The small cell base station 3 includes a base station user interface (UI) 31 , and the base station user interface 31 is responsible for transmitting a command for performing a corresponding function to the base station. For convenience of description, a device that provides a command to the base station to the small cell base station 3 through the base station user interface 31 is called a base station management device (not shown). Here, the base station management apparatus may be a device such as a computer or a server connected to the small cell base station, or a server (eg, an Operations Administration and Maintenance (OAM) server) on a network connected through the core network 4 .

The base station user interface 31 may vary depending on whether the small cell base station 3 provides an open application programming interface (API). When the small cell base station 3 provides an open API, the base station user interface 31 becomes a Web-based browser using a HyperText Transfer Protocol (HTTP) operation, and when the open API is not provided, the base station The user interface 31 may be an operation management interface of the small cell base station.

When an open API is provided, a resource for blocking data service of a mobile terminal is defined in a tree structure as illustrated in FIG. 3 .

Specifically, as shown in FIG. 3 , the resource ({apiRoot}/blockservice/v1) for data service blocking of the mobile terminal is defined as a service blocking parameter (blockService) and a parameter indicating a service blocking related time (blockTime). . The blockService parameter includes a parameter indicating the service blocking on/off state and a parameter for forcibly terminating the service (cancel). The blockTime parameter includes a parameter indicating a start time of service blocking (startBlockTime) and a parameter indicating an end time of service blocking (endBlockTime). Accordingly, the service cutoff time is composed of a service cutoff start time and a service cutoff end time.

The HTTP operation for each resource defined in this way is shown in Table 1 below. Table 1 shows HTTP operations for each resource.

Resource URL HTTP operations GET PUT POST DELETE /blockService Yes no no no /blockService/state Yes Yes no no /blockService/cancel Yes Yes no no /blockTime Yes no no no /blockTime/startBlockTime Yes Yes no no /blockTime/endBlockTime Yes Yes no no

As shown in Table 1 above, HTTP operations include GET, PUT, POST, and DELETE, and whether GET/PUT/POST/DELETE is possible (yes/no) is defined for each resource.

Next, a method for blocking a data service of a mobile terminal in a small cell base station in an embodiment of the present invention will be described.

4 is a flowchart of a method of blocking a data service of a mobile terminal according to the first embodiment of the present invention.

A first embodiment of the present invention provides a method for a small cell base station to block a data service of a mobile terminal when an open API is provided.

When the open API is provided, the base station user interface 31 functions as a web browser, and the small cell base station 3 includes a web server. In this case, the small cell base station 3 provides the data service for the mobile terminal 1 based on the resources defined in advance for blocking the data service of the mobile terminal and the data defining the availability of the HTTP operation for each resource. block

In a state in which the small cell base station 3 designates a resource using the URL and whether or not the HTTP operation is possible for it is defined, the base station management device (not shown) provides information about the resource through the base station user interface 31 . The operation may be requested from the small cell base station 3 .

Specifically, by using the HTTP operation PUT through the base station user interface 31, the state parameter (blockService/state) of the blockService is set to ON and the blockTime is requested to be set, and accordingly, the small cell base station ( 3) can block the data service by setting ON for the corresponding resource blockService/state (S100). Here, blockService and blockTime are intermediate nodes, and only GET operation is possible, and PUT operation can be performed in lower nodes.

In addition, the on/off status of blockService/state is inquired by using the HTTP operation GET through the base station user interface 31, and accordingly, the small cell base station 3 determines whether the blockService/state is on/off. By inquiring and notifying, a data service status inquiry can be made (S110).

In addition, using the HTTP operation PUT through the base station user interface 31, it is requested to set the state parameter (blockService/state) of the blockService to OFF, and accordingly, the small cell base station 3 provides the corresponding resource It is possible to cancel data service blocking by setting off for blockService/state (S120).

In addition, by requesting to set the cancel parameter (blockService/cancel) of the blockService parameter to ON using the HTTP operation PUT through the base station user interface 31, data service blocking may be forcibly terminated. Accordingly, the small cell base station 3 sets ON for the corresponding resource blockService/cancel to forcibly terminate data service blocking (S130).

In this way, for the resources defined by the small cell base station 3 for blocking the data service of the mobile terminal, data service blocking, data service status inquiry, data service blocking release, data service blocking forced termination, etc. are performed using the HTTP operation. request, and this request may be transferred to and processed by the small cell device 3 through the base station user interface 31 . As a result, it is possible to selectively block data services for mobile terminals connected to the small cell base station 3 .

Specifically, FIG. 5A is a flowchart of a process of blocking data service in the second embodiment of the present invention, and FIG. 5B is a flowchart of a process of canceling data service blocking in the second embodiment of the present invention.

A second embodiment of the present invention provides a method for a small cell base station to block a data service of a mobile terminal when an open API is not provided.

First, a process of blocking a data service in a small cell base station will be described with reference to FIG. 5A .

When receiving a command (hereinafter referred to as a blocking command) for blocking the data service of the mobile terminal from the base station management device (not shown) through the base station user interface 31 as shown in the attached FIG. 5A (S300), The small cell base station 3 checks whether the current service is being blocked (S310).

The data service blocking result is transmitted according to the checked result. If the check result indicates that the service is being blocked, a result message indicating a failure of the corresponding blocking command is transmitted to the base station user interface to notify that the service is being blocked ( S320 ).

As a result of the check, if the service is set as not being blocked, it is prohibited to block data transmission/reception between the small cell base station and the outside with a transmission/reception block in charge of external data transmission/reception of the base station (eg, a GPRS Tunnelling Protocol (GTP) block) The message is transmitted (S330). According to the prohibit message, the subsequent transmit/receive block stops transmitting/receiving data with the outside.

Thereafter, a result message for the data transmission/reception prohibition message is received from the transmission/reception block (GTP block) (S340). If the result message received from the transmission/reception block fails, a result message indicating that data service blocking according to the blocking command has failed is transmitted to the base station management device (not shown) through the base station user interface 31 (S350 and S320).

On the other hand, if the result message received from the transmission/reception block is successful, the result message indicating that data service blocking has been successfully performed according to the blocking command is transmitted to the base station management device (not shown) through the base station user interface 31 (S360) ).

Next, a process of releasing the data service blocking in the small cell base station will be described with reference to FIG. 5B .

When receiving a command (hereinafter referred to as a release command) for canceling the data service block of the mobile terminal from the base station management apparatus (not shown) through the base station user interface 31 as shown in the attached FIG. 5B (S500) ), the small cell base station 3 checks whether the current data service is being blocked ( S510 ).

A data service block release result is transmitted according to the checked result. If the check result indicates that the service is not blocked, a result message indicating failure of the corresponding release command is transmitted to the base station user interface to notify that the service is not being blocked (S520) ).

As a result of the check, if the service is set to be blocked, a release message is transmitted to the transmission/reception block (GTP block) in charge of external data transmission/reception of the base station to release blocking of data transmission/reception between the small cell base station and the outside (S530) . According to the release message, the subsequent transmission/reception block blocks data transmission/reception with the outside.

Thereafter, a result message for the data transmission/reception block release message is received from the transmission/reception block (GTP block) (S540). If the result message received from the transmission/reception block fails, a result message indicating that the data service block release according to the release command has failed is transmitted to the base station management device (not shown) through the base station user interface 31 (S550, S520) .

On the other hand, if the result message received from the transmission/reception block is successful, the result message indicating that the data service block has been successfully released according to the release command is transmitted to the base station management device (not shown) through the base station user interface 31 ( S560).

According to this embodiment, it is possible to block the data service of the mobile terminal in the small cell service area through the base station user interface of the small cell.
