Problems solved by technology

Therefore, there is a problem that even if the transmission destination of the information of the mobile communication terminal is a communication device (server) included in a private network that can be connected to the communication control system connected to the mobile communication terminal, it is still necessary to follow the At the beginning of the communication, the route of the gateway included in the mobile communication network selected by the packet switching device sends information, and the traffic increases

no. 1 Embodiment approach

[0039] figure 1 It is a block diagram showing the configuration of the communication system 1 according to the first embodiment of the present invention and their connection relationship.

[0040] A communication system 1 according to the present embodiment is composed of a communication control system 2 and a terminal connection system 3 . The communication control system 2 is composed of a base station device (Home Node B) 20 and a BB (Broad Band: broadband) router 30, and has a function of being connectable to a mobile communication network N1 and a private network N2. Furthermore, the terminal connection system 3 is a system included in the mobile communication network N1, and is composed of the line terminal device 65, the RNC 70, the SGSN 75, and the GGSN 80.

[0041] The communication control system 2 is a system that mediates communication between the mobile communication terminal 10 and the mobile communication network N1. Furthermore, the communication control syst...

no. 2 Embodiment approach

[0096] Next, a second embodiment of the communication control method of the present invention will be described. The basic configuration of the communication system of the second embodiment is the same as that of the communication system 1 of the first embodiment. The second embodiment differs from the first embodiment in the following points. That is, when the mobile communication terminal 10 has sent a communication path generation request specifying a specific APN, the communication path generation unit composed of the SGSN 75 and the GGSN 80 included in the terminal connection system 3 (communication path generation device) is utilized, Create a communication path that forwards to a specific device. Here, the specified device refers to changing the transfer destination to a device included in the private network N2 as the transfer destination when the device is specified as the transfer destination of the information transmission request transmitted from the mobile commun...

Abstract

Communication is accomplished with less traffic when communicating with a communication device included in a private network and that is also connected to a communication control system to which a mobile communication terminal is connected. A communication control system (2) can be connected with a mobile communication network (N1) and a private network (N2), and comprises: a communication request transfer unit (21) that transfers a communication path creation request transmitted from a mobile communication terminal (10) for creating a communication path specifying a device which is the transfer destination included in the mobile communication network (N1); an information transmit request receiving unit (22) that receives an information transmit request from the mobile communication terminal (10), wherein the information transmit request includes the address of a transmission destination included in the private network (N2) and transfer destination designation information that designates a transfer destination included in the mobile communication network (N1); a transfer destination change unit (23) that changes the transfer destination designation information to a device that is the transfer destination included in the private network (N2); and an information transmit request transmitting unit (26) that transmits an information transmit request to the changed transfer destination.

Description

technical field [0001] The present invention relates to a communication control system, a communication system and a communication control method. Background technique [0002] In communication via a mobile communication network of a mobile communication terminal, the mobile communication terminal requests a base station to connect to a specific communication destination by designating an APN (Access Point Name: Access Point). This connection request is transmitted from the base station to the packet switching device (SGSN: Serving GPRS Support Node, GGSN: Gateway GPRSSupport Node) via a radio control device (RNC: Radio Network Controller) included in the mobile communication network. Then, in the packet switching device, by referring to the APN included in the connection request, a gateway included in the mobile communication network used to connect to the APN is selected, and routing is performed on the gateway. Thus, the mobile communication terminal can communicate with...
