Referring to FIG. 14, when the logical bridge function layer providing the bridge function of the protocol stack according to the present invention is loaded into the card terminal 105 through the same process as that of FIG. In operation 1400, it is checked whether a packet generated corresponding to a predetermined electronic payment processing function (and / or a unique function of the card terminal 105) included in the terminal 105 flows into the logical bridge function layer.

If a packet generated corresponding to a predetermined electronic payment processing function (and / or a unique function of the card terminal 105) included in the card terminal 105 flows into the logical bridge function layer (1405), the card terminal 105 reads at least one or more packet information (eg, packet identifier, and / or packet sender address, and / or packet receiver address, etc.) included in the incoming packet via the logical bridge function layer; In operation 1410, it is determined whether the packet introduced into the logical bridge function layer is bridged into the local area communication channel connected to the card terminal 105.

According to an embodiment of the present invention, a packet approval request generated in response to the electronic payment processing function is transmitted from the card terminal 105 to the predetermined payment server 115 via the wired communication network and the van server 110. It is preferable to include the full text.

If the packet flowing into the logical bridge function layer is not bridged to the short-range communication channel on the protocol stack (1415), the card terminal 105 passes the packet through the logical bridge function layer to the card terminal 105. By providing to the wired network side MAC layer and the physical layer connected (and / or communication connection) (1420), the packet is bridged on the protocol stack and transmitted to the wired network.

According to an embodiment of the present invention, a packet provided to the wired communication network side MAC layer and the physical layer and transmitted to the wired communication network is transferred from the card terminal 105 to the predetermined payment server via the wired communication network and the van server 110. It is preferable to include the full payment approval request to be sent to (115).

Thereafter, the wired communication network transmits a packet transmitted from the card terminal 105 (for example, a packet generated in response to an electronic payment process) to a predetermined relay server (1425), and the relay server then receives the received packet. Whether or not to relay to the van server 110 and / or to a predetermined transmission destination VoIP call terminal 120, the relay server transmits the received packet to a packet generated in response to an electronic payment process. Check it.

Accordingly, the relay server relays the received packet to the van server 110 (1430), and the van server 110 receiving the packet transmits the packet (and / or the full payment approval request) to the payment. The payment server 115 which transmits to the server 115 (1435) and receives the packet (and / or payment approval request full text) performs an electronic payment processing procedure corresponding to the payment approval request full text included in the packet. After generating a packet corresponding to the electronic payment processing result (eg, a packet including a payment approval message) (1440), the packet generated corresponding to the electronic payment processing result is wired through the van server 110. The card terminal 105 is transmitted to the card terminal 105 through a communication network (1445), and the card terminal 105 receiving the packet completes the electronic payment processing procedure through the bridge function of the protocol stack as shown in FIG. 13B. .

On the other hand, if a packet introduced to the logical bridge functional layer is bridged to the short-range communication channel on a protocol stack (1415), the card terminal 105 includes the card terminal 105 in the packet through the logical bridge functional layer. The at least one packet of at least one short-range communication channel connected to the card terminal 105 by reading at least one packet information (e.g., packet identifier, and / or packet sender address, and / or packet receiver address). In step 1450, a predetermined short-range communication channel to receive is processed.

According to the exemplary embodiment of the present invention, the packet to be bridged and transmitted to the short range communication channel may include a response (and / or a short range channel connection result) to the short range communication channel request requested from the VoIP terminal 100. Then, the VoIP terminal 100 receiving the packet is assigned an address for connecting (and / or communicating) to a wired communication network to which the card terminal 105 connects (and / or communicates) through the local area communication channel. A wireline to which the card terminal 105 connects (and / or communicates) further by performing a procedure and / or using a bridge function of a protocol stack provided in the card terminal 105 through the short range communication channel. At least one VoIP call terminal 120 provided on the communication network may connect a predetermined communication channel.

In addition, a packet to be bridged and transmitted to the short-range communication channel is wired that the VoIP terminal 100 to which the short-range communication channel is connected is connected (and / or communicated with) the card terminal 105 through the card terminal 105. And a response (and / or address assignment information, and / or address assignment result) corresponding to the address assignment request requested to access (and / or connect to) the network, and then the VoIP address assigned to the address. The terminal 100 is provided on a wired communication network to which the card terminal 105 connects (and / or communicates) using the bridge function of the protocol stack provided in the card terminal 105 through the short range communication channel. At least one VoIP call terminal 120 may be connected to a predetermined communication channel.

Thereafter, the card terminal 105 determines whether to convert the packet structure of the bridge target packet into a packet structure that can be transmitted to the local area communication channel through the logical bridge function layer (1455).

If it is determined that the packet structure of the bridge target packet needs to be converted (1460), the card terminal 105 converts the bridge target packet into a packet structure capable of transmitting the bridge target packet to the local area communication channel through the logical bridge function layer. (1465).

On the other hand, if it is confirmed that the packet structure of the bridge target packet may not be converted (1460), and / or the bridge target packet is converted into a packet structure that can be transmitted through the short-range communication channel (1465), the card terminal ( 105 provides the packet to the protocol stack by providing the packet to the short-range communication channel side MAC layer and the physical layer to which the card terminal 105 connects (and / or communicates) through the logical bridge function layer (1470). It bridges over and transmits to the short range communication channel.

In the following figure, the ESD server is referred to as " server " for convenience, and the card terminal 105 is referred to as " terminal " for convenience.

Referring to FIG. 15, the terminal accesses the server through a currently connected communication network, connects a predetermined communication channel, and performs a membership registration and / or login procedure with the server (1500). In order to download and mount a predetermined program corresponding to the bridge function of the communication protocol stack, the server requests a network-based program to be loaded (1505), and correspondingly, the server inputs and provides predetermined terminal information to the terminal. The terminal provides a terminal information providing interface (1510), and the terminal inputs (or selects or extracts from, or extracts) the terminal information through the terminal information providing interface to the server through the communication network (1515). ).

Here, the terminal information includes at least one device model information and / or operating system information for the terminal.

If the check result indicates that the program corresponding to the bridge function of the communication protocol stack cannot be downloaded and mounted to the terminal (1525), the server generates predetermined program loading error information and transmits the predetermined program loading error information to the terminal through the communication network. The process of downloading and loading the program corresponding to the bridge function of the communication protocol stack to the terminal is completed (1530).

On the other hand, if it is determined that the program corresponding to the bridge function of the communication protocol stack can be downloaded and mounted to the terminal (1525), the server downloads a predetermined program file designed to provide the bridge function of the communication protocol stack to the terminal. Extract (eg, extract from the database in which the terminal information and the program file are stored in association with each other) (1535), and transmit the extracted program file to the terminal through the communication channel (1540).

The terminal receiving the program file drives the program file to back up a program file corresponding to a protocol layer that is pre-installed and operated in the terminal (eg, connecting a communication channel between the terminal and the server). (1545).
