3A is a conceptual diagram showing a cloud system communication network according to the present invention. The cloud system communication network is composed of an electronic device and an Internet Protocol (IP) server.

Referring to FIG. 3A, an electronic device may include all of electronic devices capable of wireless communication, such as a mobile terminal, a laptop, a television, and the like.

The electronic device may transmit data to the RNC control station via the Nod B base station. An RNC (Radio Network Controller) control station is also called a radio network control station. The RNC control station can perform functions for radio resource management of the asynchronous mobile communication system, management of the base station in the wireless subscriber network, and management of interfaces between the radio network controller and other network elements.

The data transmitted to the RNC control station may be transmitted to the IP server via the network. Networks can be classified as packet networks and circuit networks.

That is, when wireless communication is connected from the electronic device to the IP server, when data is split into packets and transmitted to the IP server through different paths for each packet, the data may be transmitted to the IP server through the packet network. In this case, when data is transmitted, the data path can be shared with other packets.

On the other hand, when wireless communication is connected from the electronic device to the IP server, when data is transmitted to the IP server through the same path from the start of the wireless communication to release, it can be said that the data is transmitted to the IP server through the circuit network. In this case, a predetermined data path can be used exclusively for data transmission.

In more detail, the packet network may include an SGSN and a GGSN.

Here, Serving GPRS Support Node (SGSN) is also referred to as a packet switching support node. SGSN refers to a node that is responsible for delivering data packets to and from a mobile station within a service area. The SGSN can perform packet routing and transmission functions. The location register of the SGSN may store location information of a General Packet Radio Service (GPRS) user registered in the SGSN, a user profile (e.g., International Mobile Station Identification Number (IMSI)), and the like.

Next, the Gateway GPRS Support Node (GGSN) is also referred to as a packet gateway support node. The GGSN means a node responsible for the connection function between the GPRS backbone network and the external packet data network. The GGSN converts the GPRS packet received from the SGSN into an appropriate Packet Data Protocol (PDP) format and transmits it to the IP server and converts the PDP address of the incoming packet data to the recipient's global mobile communication system (GSM) address Can be performed. In addition, the GGSN can store the user's profile and the address of the SGSN of the user stored in the location register of the SGSN.
