How to share communication protocol session of mobile terminal {COMMUNICATION PROTOCOL SESSION SHAREING METHOD FOR MOBILE TERMINAL}

The present invention relates to a method for sharing a communication protocol session of a mobile communication terminal, and in particular, a mobile communication terminal stores Point-to-Point Protocol (PPP) session information, and provides dial-up networking and wireless Internet for data communication. The present invention relates to a method of sharing a communication protocol session of a mobile communication terminal to share it when used so that a new call setup is not required to switch to another communication state.

The mobile communication terminal is configured to be used not only for voice communication but also for data communication, and such data communication has long been a basic function of the mobile communication terminal.

In particular, various methods for connecting to the Internet using data communication have been studied. Initially, a relay model for connecting to other terminals (computer or personal digital assistant) to form a dial-up network is provided. Was used.

Since then, the performance of the mobile communication terminal has been improved, and the development of display screens and the rapid growth of processing capabilities have made it possible to access wireless applications as the mobile communication terminal itself. In this case, it has been able to communicate with the network through a PPP session.

In addition, as mobile IP, which is currently being applied, has been applied, it has supported a network model that can construct a network of the Internet itself.

Thus, mobile phones now natively support both dial-up networking and wireless Internet. In addition, a personal digital assistant (PDA) equipped with a mobile phone function module can use the Internet (World Wide Web: WWW) using a general browser commonly used in a computer, rather than a dedicated browser embedded in a mobile phone.

Herein, a mobile communication terminal is a portable communication terminal capable of supporting both dial-up networking and wireless internet at the same time, and thus encompasses all terminals having such a function.

Both dial-up networking and wireless Internet are designed to communicate with the network using PPP. In practice, when using dial-up networking, the mobile terminal opens only the Radio Link Protocol (RLP) and traffic using the PPP protocol stack of the connected computer, and when using the wireless Internet, the mobile terminal has its own PPP protocol. The stack is used to communicate with the network. In both cases, a PPP session is used.

In general, PPP is a protocol that allows computers to connect to the Internet using telephone lines and modems. PPP is the most common Internet protocol that allows computers to send and receive TCP / IP packets (blocks of information transfer units on the Internet). It was originally a protocol designed for local area network (LAN) device manufacturers to connect different remote routers / bridges, but is now more commonly used as a protocol for connecting PCs and Internet service providers (ISPs).

That is, PPP performs PPP Negotiation after connecting to Internet provider, and enables real-time data transmission through IP communication to use Internet service.

The PPP is the lower layer of the PPP protocol stack.

1 illustrates a configuration of a dial-up networking for connecting a computer to an internet network when a mobile communication terminal is used as a relay model.

As shown, the computer 10 is connected to the mobile communication terminal 20 via a cable (Rm), and the mobile communication terminal 20 is connected to a base station (BS) through a wireless interface (Um) ( 30), and the base station 30 is connected to a packet switched data network (PSDN) 40.

The computer 10 has a PPP protocol stack 11 therein, and the mobile communication terminal 20 opens traffic through the PPP information and the RLP. Through this, the computer 10 is connected to the PSDN 40 by resetting the protocol stack using an emulator and receiving an IP. The emulator attempts to dial in, performs PPP negotiation, establishes a protocol stack, assigns an IP, and performs an authentication procedure.

That is, in the dial-up networking, the mobile communication terminal is in charge of only the RLP and traffic, and the PPP protocol stack above the PPP is in charge of the computer.

2 illustrates a configuration in which a mobile communication terminal is directly connected to a wireless Internet network.

As shown, the mobile communication terminal 20 is connected to the PSDN 40 through the base station 30. In this case, the mobile communication terminal 20 itself has a PPP protocol stack, and after establishing traffic using this, it sets up a protocol stack to open a PPP session and connect a call. In order to open the PPP session, a call connection and a protocol are processed and authenticated.

In summary, in each of the above-described cases, procedures for call connection and protocol are separately performed. Each service operates independently and session sharing is impossible. That is, the services are separate and use different IP information and PPP information.

In addition, the mobile communication terminal has a function called a dormant (Dormant) so that when there is no packet flow, the traffic is suspended for a while. Even if the traffic is interrupted for a while, the network and the mobile communication terminal share the open PPP session information. Therefore, the new network is automatically connected when new traffic is generated using the resource. Therefore, in both cases, the mobile communication terminal is not always connected to the network, traffic is generated or stopped according to the packet flow, and the mobile communication terminal shares the PPP session information with the PSDN.

3 is a flowchart illustrating a procedure of changing a data communication mode through a conventional mobile communication terminal, and a procedure in which a mobile terminal currently completes a procedure for a protocol when initial access to the wireless Internet, that is, when dialing networking is desired while using the wireless Internet. It is shown.

Since the mobile communication terminal is currently using the wireless Internet, the call is terminated and the PPP session is terminated.

The mobile communication terminal sends a release order to the network to inform the network that the current call has ended.

The above procedure occurs when the user terminates the wireless Internet access through the user menu setting of the mobile communication terminal.

The user then selects dial-up networking, so that the procedures for dial-up networking are carried out in a separate procedure.

First, a mobile communication terminal and a computer are connected using a data cable for dial-up networking.

Then, when a telephone connection is attempted using an emulator of a computer, the mobile communication terminal connects the computer with the PSDN through an air interface with the base station and performs PPP procedure, IP allocation, and authentication procedure.

Then, the protocol is set up, call connection is made, and the Internet is available.

In other words, in order to use separate services, new services must be reconfigured from the beginning after the existing services are completely terminated.

As described above, since the PPP session of the conventional mobile communication terminal proceeds in a separate procedure according to the service used, in order to change the service because the PPP session cannot be shared, the protocol procedure for the new service is completely terminated after the current service is completely used. And there is a problem that the IP allocation must be redone from the beginning, which has a problem that the burden on the PSDN network.

In view of the above problems, the present invention stores the PPP session information set in the service currently being used by the mobile communication terminal and changes to the idle state by the service change instruction of the user, and then connects the new service using the stored PPP session information. It is an object of the present invention to provide a method for sharing a communication protocol session of a mobile communication terminal to enable a call connection without a new protocol procedure.

In order to achieve the above object, the present invention provides a communication protocol session sharing method of a mobile communication terminal supporting a dial-up anti-working service and a wireless Internet service, and includes a packet exchange for using one of the two different services. Communicating with a data network (PSDN) to perform protocol procedures, IP allocation, and authentication procedures, and then sharing communication protocol session information in the PSDN with the mobile communication terminal; Forcing the mobile communication terminal into a dormant state when a user wants to use another service according to a user's setting; If another service is driven according to a user's selection, the method may include establishing and connecting a call using communication protocol session information stored in the mobile communication terminal.

The communication protocol session information is characterized in that the PPP protocol session information.

The selection of the user may be performed according to a menu operation of the mobile communication terminal.

Hereinafter, with reference to the accompanying Figure 4 of the present invention configured as described above will be described in detail.

Figure 4 is a flow chart showing the procedure of an embodiment of the present invention, showing the improvement to the prior art shown in Figure 3, the initial state is also the same.

Currently, the mobile communication terminal shows the procedure when the procedure for the protocol is completed at the initial access of the wireless Internet, that is, when the user wants dial-up networking while using the wireless Internet.

The user operates the menu setting of the mobile communication terminal to set the wireless Internet currently being used in the standby mode.

When the standby mode is set, the terminal stores PPP session information (including IP information) that has been shared with the current PSDN and is forced into a dormant state (Dormant).

In this case, even if the wireless Internet function is terminated, the portable terminal maintains the PPP session information shared with the PSDN.

Thereafter, the mobile communication terminal and the computer are connected by a cable for dial-up networking to configure an interface.

Then, when the computer attempts to connect by starting the emulator, the PPP session information stored in the portable terminal is used as it is, and the call can be set up immediately without the PPP procedure.

Although the above method illustrates a procedure of changing a service to a dial-up network while using a wireless Internet, the same method may be applied to a case of changing a service to a wireless Internet while using a dial-up network. Since the PPP session information is shared with the PSDN, the PPP session information can be stored according to the user's selection, and the forced transition to the idle state can be performed without completely terminating communication with the PSDN.

Since some of the procedures of the above embodiments may be performed simultaneously or may be reversed, various changes to the order are encompassed in the present invention.

As described above, by applying the PPP session information shared by the current mobile communication terminal and the PSDN to other services, the PSDN and the mobile communication terminal do not need to open different PPP sessions through a new PPP procedure. As it becomes available, PSDNs are free from the burden of new PPP procedures. In addition, the user can also use the fast service.

The specific embodiments or examples made in the detailed description of the present invention are intended to clarify the technical contents of the present invention to the extent that they should not be construed as limited to these specific embodiments and should not be construed in consultation. Various changes can be made within the scope of.

As described above, the present invention stores the PPP session information set for the communication connection service currently being used by the mobile communication terminal according to the user's selection of the standby mode, changes to the idle state forcibly, and then provides a new service by changing the service of the user. By using the stored PPP session information to connect to enable the call connection without a new protocol procedure, it is possible to efficiently use the network resources, the user can also switch the fast service.
