Description

Data communication method of wireless terminal using Phi Phi communication method {Method of communication between the mobile terminals using the PPP communication mode}

The present invention relates to a data communication method of a wireless terminal using PPP (Point-to-Point Protocol communication mode), more specifically, the originating wireless terminal has a dynamic IP (Dynamic Internet Protocol) of the receiving wireless terminals Even under the circumstances, the data communication method of the wireless terminal using the PPP communication method can be induced to freely form a 1: 1 communication type, 1: N type simultaneous communication relationship with the corresponding receiving terminal wireless terminal. It is about.

Recently, with the rapid development of communication technology, various kinds of wireless terminals equipped with wireless modems, wireless telephones, etc., for example, notebook PCs, PDAs (Personal Digital Assistants), and the like, have been widely distributed. Various types of data communication schemes, such as PPP communication schemes, have been developed to ensure data communication.

As shown in Fig. 1, under the conventional PPP communication scheme, any wireless terminal 4 is a PPP server (2: Point-to-Point Protocol server) via the radio base station 6 and the communication network 1; By accessing the Internet service providing server 3 established in the communication network 1, after obtaining a series of dynamic IP address (Dynamic Internet Protocol address). It is possible to easily enjoy a variety of Internet services, for example, a World Wide Web service, a File Transfer Protocol service, and the like. Of course, the wireless terminal 4 utilizes a series of data transmission / reception methods such as a circuit communication mode, a packet communication mode, and the like in another PPP communication environment. A series of data communication can be achieved with 5).

However, a conventional data communication method, for example, a line communication method, is generally based on "a form in which specific transmitting and receiving wireless terminals 4 and 5 in communication fully occupy one communication line assigned between them". Therefore, under such a line communication system, the wireless terminal 4 can only perform 1: 1 communication with one other wireless terminal 5 communicating with itself, and other wireless terminals 5a, 5b. It is not possible to form a separate simultaneous communication relationship. That is, under the conventional line communication system, the wireless terminal 4 can only form a 1: 1 type communication relationship, for example, cannot establish a 1: N type simultaneous communication relationship at all.

On the other hand, since the conventional packet communication method is based on "a type in which several wireless terminals participating in the communication share a communication line together", under this packet communication system, the wireless terminal 4 communicates with itself. Not only one other wireless terminal 5 in use, but also other wireless terminals 5a, 5b ... can form a separate simultaneous communication relationship. That is, under the conventional packet communication system, the wireless terminal 4 can easily establish a 1: 1 communication type as well as a 1: N type communication relationship.

However, in order for the wireless terminal 4 to form a 1: 1 or 1: N type simultaneous communication relationship through a conventional packet communication method, other wireless terminals 5 and 5a communicating with the wireless terminal 4 are described. , 5b ... shall have a high-priced fixed IP address. " That is, even in the packet communication scheme, if other wireless terminals 5, 5a, 5b ... are having low-price dynamic IP addresses, The wireless terminal 4 cannot form a 1: N simultaneous communication relationship or even a 1: 1 communication relationship at all.

This is because if other receiving wireless terminals 5, 5a, 5b ... are in communication with any originating wireless terminal 4, they have " dynamic IP addresses whose values fluctuate depending on the situation. &Quot; This is because the source wireless terminal 4 cannot accurately determine the positions of the receiving wireless terminals 5, 5a, 5b ... to which the packet should be transmitted.

Of course, under this situation, the originating side wireless terminal 4 is forced to abandon the packet transmission itself to the communication target receiving side wireless terminal 5, 5a, 5b ....

In short, under the conventional system, the wireless terminal 4 is "a problem that a 1: N simultaneous communication relationship cannot be formed at all under the line communication system", and "receiving wireless terminals 5, even in a packet communication system". , 5a, 5b ...) and the low-cost dynamic IP possession situation can not only form a 1: N simultaneous communication relationship, but also a 1: 1 communication relationship. "

Accordingly, an object of the present invention is to correspond to a short message of a serial communication type which can be easily transmitted to any receiving wireless terminal only by an identification code other than an IP address, for example, a telephone number. It can be used as a means to grasp the dynamic IP of the receiving wireless terminal, and through this, even when the calling wireless terminal possesses the dynamic IP retention status of the receiving wireless terminals, the 1: 1 wireless communication relationship with the corresponding receiving wireless terminals is achieved. , 1: N-type simultaneous communication relationship can be formed freely.

In order to achieve the object described above, in the present invention, any caller's wireless terminal transmits a short message including a self identification number to the corresponding receiver's wireless terminal by utilizing the identification number of the specific receiver's wireless terminal. After transmitting, the receiving wireless terminal accesses the PPP server, obtains the dynamic IP address, and then sends the data including the self-dynamic IP address and the identification number of the calling wireless terminal to the SMS message server (Short Message Service call server). Transmitting, by the SMS call server, a short message including the dynamic IP address of the receiving wireless terminal to the calling wireless terminal by using the identification number of the calling wireless terminal, After accessing the PPP server to obtain the dynamic IP address, the receiver side receives the data in which the self dynamic IP address is described. Disclosed is a data communication method of a wireless terminal using a PPP communication method which uses a combination of the steps of transmitting to a corresponding receiving wireless terminal by utilizing the dynamic IP address of the wireless terminal.

Hereinafter, a data communication method of a wireless terminal according to the present invention will be described in more detail with reference to the accompanying drawings.

As shown in FIG. 2, under a PPP communication scheme using a PPP communication scheme according to an embodiment of the present invention, for example, a User Datagram Protocol (UDP: hereinafter referred to as “UDP”), The originating radio terminal 10, the receiving radio terminal 11, and the like may connect to the PPP server 20, the SMS call server 30, and the like via the radio base station 6, the communication network 1, and the like. . In this case, the PPP server 20, the SMS call server 30, and the like are operated and managed by the wireless communication service provider.

In a state where such a base environment is provided, when a full-scale data communication process is performed, as shown in FIG. 3, first, the calling party's wireless terminal 10 has a short message including its identification number, for example, its own telephone number. After generating the call, the call is set to the identification number of the receiving wireless terminal 11 inputted by the user, for example, the telephone number of the receiving wireless terminal, so that the preceding short message is promptly sent to the receiving wireless terminal 11. To be transmitted (step S1).

In general, since the preceding short message is transmitted and managed in the serial communication layer, not in the IP protocol layer of each of the wireless terminals 10 and 11, the calling party's wireless terminal 4 Even in a situation in which the IP address of the receiving radio terminal 11 is not known, it is possible to easily transmit a desired short message to the receiving radio terminal 11 only by using the telephone number of the receiving radio terminal 11.

Through the above process, when a short message including the telephone number of the calling party wireless terminal 10 is transmitted and completed, the receiving party receiving the wireless terminal 11 accesses the PPP server 20, thereby providing its own dynamic IP. An address is obtained (steps S2 and S3). According to this process, the communication layer of the receiving wireless terminal 11 is adjusted upward from the serial communication layer to the UDP communication layer.

Subsequently, the receiving side wireless terminal 11 generates a series of UDP data including its dynamic IP address and the telephone number of the calling side wireless terminal 10 obtained through the above-described process, and then generates the UDP data, for example. , Using the UDP / IP protocol, proceeds to the transmission to the SMS call server 30 (step S4).

Through the above-described process, when a series of UDP data including the IP address of the receiving wireless terminal 11 and the telephone number of the calling wireless terminal 10 is transmitted and completed, the SMS call server 30 automatically transmits the SMS. Using a generation module (not shown), after generating a short message describing the dynamic IP address of the receiving wireless terminal 11, the short message is referred to as, for example, an identification number of the calling wireless terminal 10, for example, a telephone. Using the number, the process of transmitting to the calling party's wireless terminal 10 is progressed (step S5). In the end, when such a process is completed, the calling party's wireless terminal 10 of the receiving party's wireless terminal 11 Dynamic IP addresses can be obtained easily.

In the conventional case, when other receiving wireless terminals communicating with any calling wireless terminal have a "dynamic IP address whose value fluctuates depending on the situation," the calling wireless terminal transmits the packet to itself. Since the location of the receiver wireless terminals to be located could not be accurately determined, a series of communication relationships could not be established with the receiver wireless terminals.

However, in the case of the present invention, as mentioned above, a short message of serial communication type that can be easily transmitted to any receiving wireless terminal 11 only by an identification code other than an IP address, for example, a telephone number, is applicable. Since the dynamic IP of the receiving wireless terminal 11 is utilized as a means for identifying the dynamic IP, under the system of the present invention, the calling wireless terminal 10 has a situation where the other receiving wireless terminal 11 to communicate with itself is “situation”. Even if it possesses a dynamic IP address "whose value varies dynamically, it is possible to accurately determine the position of the receiving wireless terminal 11 to which the packet should be transmitted. ) And a series of communication relationships can be easily formed.

On the other hand, in the situation where the dynamic IP address of the receiving wireless terminal 11 is obtained through the above-described process, the calling wireless terminal 10 obtains its own dynamic IP address by connecting to the PPP server 20. (Steps S6, S7). According to this process, the communication layer of the originating wireless terminal 10 is adjusted upward from the serial communication layer to the UDP communication layer.

Subsequently, the calling party wireless terminal 10 generates a series of UDP data including its own dynamic IP address obtained through the above-described process, and then uses the UDP data, for example, the dynamic IP of the receiving wireless terminal 11. Using the address, a process of transmitting to the receiving side wireless terminal 11 is performed (step S8).

Through the above-described process, when the dynamic IP address of the calling party wireless terminal 10 is transmitted and completed to the receiving party wireless terminal 11, the calling party wireless terminal 10 and the receiving party wireless terminal 11 are dynamic with each other. As a result, both the IP address and the receiving wireless terminal 10 and the receiving wireless terminal 11 can easily form, for example, a 1: 1 type PPP communication connection relationship. The side radio terminal 10 can freely transmit a series of communication data with respect to the reception side radio terminal 11 (step S9).

On the other hand, as shown in Figure 4, under the PPP communication scheme using a PPP communication scheme, for example, a Transmission Control Protocol (TCP) according to another embodiment of the present invention, hereinafter referred to as "TCP", The arbitrary calling party radio terminal 10, the receiving party radio terminal 11, etc. can connect to the PPP server 20, the gateway server 40, etc. via the radio base station 6, the communication network 1, etc. . In this case, the PPP server 20, the gateway server 40, and the like are operated and managed by the wireless communication service provider.

In this state of infrastructure, when a full-scale data communication process proceeds, as shown in FIG. 5, first, the calling party's wireless terminal 10 accesses the PPP server 20 to obtain its dynamic IP address. Acquire (steps S20, S21). According to this process, the communication layer of the originating wireless terminal 10 is adjusted upward to the TCP communication layer.

Subsequently, the calling party wireless terminal 10 generates a series of TCP data including its own telephone number and the telephone number of the receiving wireless terminal 11, and then uses the TCP data, for example, using the TCP / IP protocol, The transmission to the gateway server 40 is performed (step S22).

Through the above-described process, when a series of TCP data including the telephone number of the calling party wireless terminal 10 and the telephone number of the receiving wireless terminal 11 is transmitted and completed, the gateway server 40 immediately sends the calling party to the calling party. After assigning a series of dedicated TCP connection ports for the wireless terminal 10, the identification number of the corresponding calling party wireless terminal 10 and the number of the dedicated TCP connection port for the calling party wireless terminal 10 are assigned. It registers and stores in own map data management module (not shown) (step S23).

Subsequently, the gateway server 40 generates a short message including the telephone number of the calling party's wireless terminal 10 by using the SMS generation module provided therein, and then generates the short message, for example, the receiving party's wireless terminal 11. By utilizing the telephone number of the, the process of transmitting to the corresponding receiving side wireless terminal 11 is performed (step S24).

As described above, since the short message is usually transmitted and managed in the serial communication layer of each wireless terminal, even if the gateway server 40 does not yet know the position of the receiving side wireless terminal 11, only the receiving side Only the phone number of the wireless terminal 11 can easily transmit its desired short message to the corresponding receiving side wireless terminal 11.

Through the above process, when a short message including the telephone number of the calling party wireless terminal 10 is transmitted and completed, the receiving party receiving the wireless terminal 11 accesses the PPP server 20, thereby providing its own dynamic IP. An address is obtained (steps S25, S26). According to this process, the communication layer of the receiving wireless terminal 11 is adjusted upward from the serial communication layer to the TCP communication layer.

Subsequently, the receiving wireless terminal 11 generates a series of TCP data in which its own telephone number is written, and then transmits the TCP data to the gateway server 40 using, for example, the TCP / IP protocol. (Step S27).

Through the above-described process, when a series of TCP data in which the telephone number of the reception side wireless terminal 11 is described is transmitted and completed, the gateway server 40 immediately proceeds to the reception side wireless terminal 11, After allocating a dedicated TCP connection port, the telephone number of the receiving wireless terminal 11 and the number of the dedicated TCP connecting port of the receiving wireless terminal 11 are registered and stored in their own map data management module (step S28). .

All of these processes are completed, and the telephone number of the calling party wireless terminal 10, the TCP connection port number dedicated to the calling party wireless terminal 10, and the receiving party's wireless terminal 11 are stored in the map data management module of the gateway server 40. When the telephone number, the TCP connection port number dedicated to the receiving wireless terminal 11, and the like are registered and stored, the calling wireless terminal 10 and the receiving wireless terminal 11 are eventually routed through the gateway server 40. The location between each other can be grasped, and as a result, the originating radio terminal 10 and the receiving radio terminal 11 can easily form, for example, a 1: 1 type PPP communication connection relationship. The calling party's wireless terminal 10 against the receiving party's wireless terminal 11; A series of communication data can be freely transmitted (step S29).

As described above, in another embodiment of the present invention, a serial message type short message that can be easily transmitted to any receiving wireless terminal using only a telephone number is used as "means for inducing connection of the receiving wireless terminal." Therefore, under the system of the present invention, the gateway server 40 is a receiver of the receiving wireless terminal 11 to be connected to the communication with the calling wireless terminal 10 "dynamic IP address whose value varies flexibly according to the situation". Even if it holds, the receiving wireless terminal 11 can be reliably communicated with the calling wireless terminal 10.

On the other hand, as shown in Fig. 6, under the PPP communication system having a PPP server 20, SMS call server 30 and the like, for example, PPP communication system using UDP, any originating wireless terminal 10 Not only can establish a 1: 1 communication connection relationship with the receiving wireless terminal 11, but also establish a 1: N simultaneous communication connection relationship with a plurality of other receiving wireless terminals (‥ 12 ‥ 13 ‥). can do. Of course, even if the originating radio terminal 10 establishes a 1: N connection relationship with other receiving radio terminals (... 12 ... 13 ...), the originating radio terminal 10 is the receiving radio terminal 11. It is possible to maintain the communication connection with the same.

First, as shown in FIG. 7, when a full-scale data communication process is performed, the calling party's wireless terminal 10 receives a receiver's radio other than its own dynamic IP address and the receiver's wireless terminal 11 to which it is signaling. After generating a series of UDP data describing the telephone numbers of the terminals (e.g., 12 ... 13 ...), for example, the other receiving wireless terminal 12, this UDP data is used, for example, using an UDP / IP protocol to call an SMS. The process of transmitting to the server 30 is performed (step S10). Of course, this process is possible because the originating wireless terminal 10 has been adjusted up from its serial communication layer to the UDP communication layer through the above-mentioned step S6, S7.

Through the above-described process, when UDP data including the dynamic IP address of the calling party wireless terminal 10 and the phone number of the receiving wireless terminal 12 is transmitted and completed, the SMS call server 30 generates an SMS provided by itself. The module generates a short message describing the dynamic IP address of the calling party's wireless terminal 10, and then uses the short message, for example, by utilizing the telephone number of the receiving party's wireless terminal 12, and the corresponding receiving party's wireless terminal. The process of transmitting to step 12 is performed (step S11).

Through the above-described process, when the dynamic IP address of the originating radio terminal 10 is transmitted, the other receiving radio terminal 12 immediately obtains its own dynamic IP address by connecting to the PPP server 20. (Steps S12, S13). According to this process, the communication layer of the other receiving side wireless terminal 12 is adjusted upward from the serial communication layer to the UDP communication layer.

Subsequently, the other receiving wireless terminal 12 generates a series of UDP data describing its dynamic IP address obtained through the above-described process, and then converts the UDP data into, for example, the dynamic of the calling wireless terminal 10. Using the IP address, the process of transmitting to the calling party's wireless terminal 10 is performed (step S14).

Through the above-described process, when the dynamic IP address of the other receiving wireless terminal 12 is transmitted and completed to the calling wireless terminal 10, the calling wireless terminal 10 and the receiving wireless terminal 12 mutually communicate with each other. All the dynamic IP addresses can be known, and as a result, the originating wireless terminal 10 and the other receiving wireless terminal 12 can easily form a 1: 1 type PPP communication connection relationship, for example, The calling party radio terminal 10 can easily form a PPP simultaneous communication connection relationship of, for example, 1: N type, such as the receiving party wireless terminal 11, the receiving party wireless terminal 12 (step S15).

Subsequently, the originating side wireless terminal 10 further proceeds the above-described steps S11 to S15, so that it is possible to easily form, for example, a 1: 1 type PPP communication connection relationship with another receiving side wireless terminal 13. As a whole, the receiving side wireless terminal 11, the receiving side wireless terminal 12, the receiving side wireless terminal 13, and the like, for example, can easily form a 1: N type PPP communication connection relationship.

On the other hand, as shown in FIG. 8, under the PPP communication system including the PPP server 20, the gateway server 40, and the like, for example, the PPP communication system using TCP, any originating wireless terminal 10 may be used. Not only can a 1: 1 communication connection be established with the receiving wireless terminal 11, but also a 1: N simultaneous communication connection can be formed with a plurality of other receiving wireless terminals (‥ 12 ‥ 13 ‥). Can be. Of course, as in the previous case, even if the originating radio terminal 10 establishes a 1: N connection relationship with the other receiving radio terminals (... 12 ... 13 ...), the originating radio terminal 10 receives the reception. The communication connection relationship with the side wireless terminal 11 can be maintained as it is.

First, as shown in FIG. 9, when a full-scale data communication process is performed, the calling party wireless terminal 10 receives other receiving party wireless terminals other than the receiving party wireless terminal 11 to which the signal is connected. 13), for example, after generating a series of TCP data in which the telephone numbers of the other receiving side wireless terminals 12 are written, and transmitting the TCP data to the gateway server 40 using, for example, the TCP / IP protocol. The process proceeds (step S30). Of course, this process is possible because the originating wireless terminal 10 has been adjusted up to its own communication layer to the TCP communication layer through the above-mentioned step S20, S21.

Through the above-described process, when the TCP data including the phone number of the other receiving side wireless terminal 12 is transmitted and completed, the gateway server 40 utilizes an SMS generation module provided in itself, and thus the calling side wireless terminal 10. After generating a short message in which the phone number is described, the short message is transmitted to the corresponding receiving terminal wireless terminal 12 using, for example, the telephone number of the receiving wireless terminal 12 (step S31). ).

Through the above process, when a short message including the telephone number of the calling party wireless terminal 10 is transmitted and completed, the other receiving party wireless terminal 12 which has received it is connected to the PPP server 20, thereby providing its own dynamic message. Obtain an IP address (step S32). According to this process, the communication layer of the other receiving side wireless terminal 12 is adjusted upward from the serial communication layer to the TCP communication layer.

Subsequently, the other receiving terminal wireless terminal 12 generates a series of TCP data including its own telephone number, and then transmits the TCP data to the gateway server 40 using, for example, the TCP / IP protocol. Proceed (step S33).

Through the above-described process, when a series of TCP data in which the telephone number of the other receiving side wireless terminal 12 is written is completed and completed, the gateway server 40 immediately targets the other receiving side wireless terminal 12. After assigning a series of dedicated TCP connection ports, the telephone number of the other receiving wireless terminal 12 and the dedicated TCP connecting port number of the receiving wireless terminal 12 are registered and stored in their own map data management module (step). S34).

All these processes are completed, and the telephone number of the calling party wireless terminal 10, the TCP connection port number dedicated to the calling party wireless terminal 10, and the other receiving wireless terminal 12 are stored in the map data management module of the gateway server 40. When the telephone number of the terminal, the TCP connection port number of the other receiving wireless terminal 12, and the like are registered and stored, eventually, the calling wireless terminal 10 and the other receiving wireless terminal 12 communicate with the gateway server 40. As a result, the position of each other can be grasped, and as a result, the originating wireless terminal 10 and the receiving wireless terminal 12 can easily form, for example, a 1: 1 type PPP communication connection relationship. In general, the originating wireless terminal 10 can easily form a PPP simultaneous communication connection relationship of, for example, 1: N type, with the receiving wireless terminal 11 and the receiving wireless terminal 12 (step S36). .

Subsequently, the originating side wireless terminal 10 further proceeds with the above-described steps S30 to S36, so that the receiving side wireless terminal 13 can easily form, for example, a 1: 1 type PPP communication connection relationship with another receiving side wireless terminal 13. In general, it is possible to easily form a PPP simultaneous communication connection relationship of, for example, 1: N type with the receiving wireless terminal 11, the receiving wireless terminal 12, the receiving wireless terminal 13, and the like.

As described in detail above, in the present invention, a short message of a serial communication type that can be easily transmitted to any receiving wireless terminal using only an identification code other than an IP address, for example, a telephone number, can be used. It can be used as a means to identify the IP, and through this, even if the calling wireless terminal has a dynamic IP retention status of the receiving wireless terminals, the 1: 1 wireless communication relationship with the corresponding receiving wireless terminals, 1: N type It can be induced to freely form a simultaneous communication relationship.

While specific embodiments of the invention have been described and illustrated above, it will be apparent that the invention may be embodied in various modifications by those skilled in the art.
