Therefore, the present invention is not limited to the embodiments described herein and may be embodied in other forms. The embodiments disclosed herein are provided so that the disclosure can be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

In this specification, when it is mentioned that a certain element includes an element, it means that it may further include other elements. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 exemplarily illustrates a mobile network according to the present invention. Referring to FIG. 1, the mobile network system 100 includes a plurality of mobile terminals M1, M2, M3, M4, M5, M6, M7, and M8.

The mobile network system 100 may include a mobile network connecting mobile terminals. For example, the first mobile network 110 includes mobile terminals M1, M2, M3. The second mobile network 120 includes mobile terminals M2, M4, M5. Mobile terminals belonging to each of the mobile networks 110 and 120 perform group communication with each other. Meanwhile, in the mobile network system 100 according to the present invention, each of the mobile networks 110 and 120 does not need a separate relay device or a separate network control device. For example, the first mobile network 110 configures the network only with the mobile terminals M1, M2, and M3 included in the mobile network 110, and does not require a separate relay device.

According to the above configuration, the mobile network system 100 may form a mobile network composed of only mobile terminals. Thus, the mobile network system 100 can form a mobile network more fluidly and simply.

FIG. 2 is a block diagram illustrating a mobile terminal shown in FIG. 1. Referring to FIG. 2, the mobile terminal 200 includes an interface unit 210, a group list processing unit 220, a history managing unit 230, and a network managing unit 240.

The configuration and operation of the mobile terminal 200 shown in FIG. 2 are substantially the same as those of the mobile terminals M1, M2, M3, M4, M5, M6, M7, and M8 shown in FIG. 1.

The mobile terminal 200 interfaces with the peripheral terminal 300. In addition, the mobile terminal 200 configures a mobile network with the peripheral terminal 300. Herein, the mobile network is substantially the same in configuration and operation as the mobile networks 110 and 120 illustrated in FIG. 1.

The interface unit 210 interfaces with the peripheral terminal 300 to transmit and receive a communication signal. In an embodiment, the communication signal may be a wireless signal. The interface unit 210 may generate a unique protocol for communicating with the peripheral terminal 300. The signal received by the mobile terminal 200 from the peripheral terminal 300 may be transmitted to each unit 220, 230, 240 of the mobile terminal 200 through the interface unit 210.

The group list processor 220 collects and manages terminal information of the peripheral terminal 300. The group list processor 220 generates a terminal list that can interface with the mobile terminal 200 with reference to the collected terminal information. The group list processing unit 220 generates a group communication list for performing group communication with reference to the generated terminal list.

Meanwhile, although only one peripheral terminal 300 is illustrated in FIG. 2, the number of peripheral terminals for which the group list processing unit 220 collects terminal information may be two or more.

The history manager 230 manages group communication history of the mobile terminal 200. In addition, the history manager 230 stores the group communication history of the mobile terminal 200. The history may indicate the content of group communication performed by the mobile terminal or the mobile network formed by the mobile terminal 200.

The network manager 240 manages the networking of the mobile terminal 200. The network manager 240 controls networking or group communication of the mobile terminal 200 with reference to the network management table. That is, the network manager 240 determines peripheral terminals to interface with the mobile terminal 200 according to the network management table. In addition, the network manager 240 generates or changes a network management table.

In an embodiment, the network manager 240 may change the network management table by referring to a communication signal provided from the peripheral terminal 300. In an embodiment, the network manager 240 may provide a result of changing the network management table to the peripheral terminal 300 as a communication signal. The communication signal transmission between the network manager 240 and the peripheral terminal 300 is performed through the interface unit 210.

Details of the mobile network configuration method of the mobile terminal 200 will be described later.

The mobile terminal 200 may include a controller (not shown) or a central processing unit (not shown) for controlling the general operation of the mobile terminal and the operations of the units 201, 220, 230, and 240. The control unit (not shown) or the central processing unit (not shown) is a configuration generally included in the mobile terminal device, and details thereof are well known in the art, and thus description thereof will be omitted.

According to the above configuration, the mobile terminal 200 interfaces with the peripheral terminal 300 to generate a network management table. In addition, the mobile terminal 200 configures a mobile network to perform group communication with reference to the network management table.

Therefore, the mobile network can be configured only by the interface between the mobile terminals. As a result, there is no need for a separate relay device for mobile network configuration. In addition, the mobile network may be flexibly configured. Meanwhile, since group communication is performed between mobile terminals, access from a terminal not included in the group communication may be blocked. As a result, the security performance of the mobile terminal can be improved.
