The present invention relates to a method for terminating a connection when a wireless communication terminal is not used for a predetermined time after a WAP connection. More specifically, the present invention relates to a packet data service node (PDSN) in a wireless communication terminal. When the WAP is connected and connected, the PDSN is connected to the PDSN after the time set in PDSN PPP inactivity timer and PDSN PPP session timer. In case of non-use for a certain period of time after WAP connection in a wireless communication terminal to terminate the WAP connection by the WAP session timer by terminating the Point-to-Point Protocol (PPP) It is about a termination method.

In the present invention, a wireless communication terminal is a mobile communication terminal, a personal mobile communication terminal (PCS), a personal digital assistant (PDA), a smart phone, a next generation mobile communication terminal (IMT-2000), such as a wireless LAN terminal while carrying the individual A terminal capable of wireless communication.

1 is a diagram illustrating an exemplary embodiment of a conventional WAP protocol.

The WAP 2.0 protocol stack includes a WAP device equipped with the Wireless Application Environment (WAE) / HTTP / Transport Layer Security (TCP) / TCP * / IP / Wireless protocols, and TCP * / IP / Wireless and TCP / IP / It includes a WAP Proxy that acts as a gateway that interoperates with the Wired protocol, and a Web Server equipped with a Wireless Application Environment (WAE) / HTTP / TLS (Transport Layer Security) / TCP / IP / Wired protocol. do.

2 is a diagram illustrating an embodiment of a protocol stack of a conventional WAP terminal and a packet data service node (PDSN).

As shown in FIG. 2, a conventional WAP terminal and a packet data service node (PDSN) connection system include a WAP protocol mounted on an IP / PPP / LAC / MAC / Airlink layer. Mobile Station (MS), Radio Node (RN) interworking LAC / MAC / Airlink and RP / PL layer for mobile communication, Packet for processing wireless data protocol set in terminal for packet data service Packet Data Service Node (PDSN), End Host with WAP Proxy in IP / Link Layer / Physical Layer, and WAE / HTTP / TLS / TCP / IP / Wired Protocol It includes a mounted web server (not shown).

Here, the link access control (LAC) layer is applied only to signaling, and the medium access control (MAC) layer is multiplexed, radio link protocol (RLP), and quality of service: QoS).

However, in the related art, the WAP session is terminated when the user inputs the WAP end key of the wireless communication terminal using the WAP protocol. If the user does not want (inadvertently connected), if the WAP is executed, the PPP session is connected to send and receive unnecessary data, which causes a load on the wireless terminal.

The present invention has been proposed to solve the above problems, and when the wireless communication terminal is connected to the packet data service node (PDSN) to access the WAP (WAP), PDSN PPP inactive when not used for a certain time After the time set by the PDSN PPP inactivity timer and PDSN PPP session timer, the Point-to-Point Protocol (PPP) connected to the PDSN is terminated to Accordingly, an object of the present invention is to provide a method for terminating a connection when a wireless communication terminal is not used for a predetermined time after a WAP connection for terminating a WAP connection.

Other objects and advantages of the present invention can be understood by the following description, and will be more clearly understood by the embodiments of the present invention. It will also be appreciated that the objects and advantages of the present invention may be realized by the means and combinations thereof indicated in the claims.

The method of the present invention for achieving the above object, in the connection termination method after a non-use for a predetermined time after the WAP (WAP) connection in the wireless communication terminal, PDSN PPP inactivity timer and PDSN PPP session timer in the setting menu of the wireless communication terminal Setting up; Initiating a WAP connection and counting time while the PDSN PPP session timer is running as the swap is executed; As the WAP transitions to an inactive state, driving the PDSN PPP inactivity timer to count time, and resetting the PDSN PPP inactivity timer as awake from a WAP dormant state; Generating a swap client termination event to terminate each timer as either one of the PDSN PPP session timer and the PDSN PPP inactivity timer elapses; And a session termination step of terminating a swap session as the PDSN PPP session timer is not completed.

The above objects, features, and advantages will become more apparent from the following detailed description taken in conjunction with the accompanying drawings, whereby those skilled in the art may easily implement the technical idea of the present invention. Could be. In describing the present invention, when it is determined that the detailed description of the known technology related to the present invention may unnecessarily obscure the gist of the present invention, the detailed description thereof will be omitted.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

3 is a flowchart illustrating a method for terminating access when not in use for a predetermined time after a swap connection in a wireless communication terminal according to the present invention.

(1) The user sets a WAP timer (PDSN PPP inactivity timer, PDSN PPP session timer) in a setting menu of the terminal (20).

Setting menu

PDSN PPP inactivity timer (time count after dormant)

  1: 20 minutes

  2: 40 minutes

  3: 1 hour

PDSN PPP session timer (time count since connection)

  1: 1 hour

  2: 1 hour 30 minutes

  3: 2 hours

(2) When the WAP connection is started and the WAP is executed (Web execution) 21, the time is counted while driving the PDSN PPP session timer (22).

(3) When the WAP dormant timer is operated and the WAP is in the inactive state (the WAP dormant state) (23), the PDSN PPP inactivity timer is started, and the time is counted. (24)

(4) When waking from the WAP dormant state (25), the PDSN PPP inactivity timer is reset (26).

(5) After a predetermined time (for example, 20 minutes) in which one of the PDSN PPP session timer and the PDSN PPP inactivity timer are set, a swap client termination event is generated to terminate the timer. (27).

(6) When the PDSN PPP session timer is completed (28), if the user is browsing (Browsing), the session timer end message is displayed on the user screen, and whether or not to set the PDSN PPP session timer again. Ask (29).

(7) If the user continues to use, the PDSN PPP session timer is started again after the PDSN PPP session timer reset (time), the time is counted (30).

On the other hand, if the PDSN PPP session timer has not completed, the client of the terminal generates a swap client termination event in order to terminate the WAP session normally (31). A swap session disconnect message (LCP Term message) ) Is transmitted to a WAP server to terminate a Point-to-Point Protocol (PPP) connected to a base station's WAP Gateway and a Packet Data Service Node (PDSN) (32).

(9) The WAP session of the terminal terminates normally and becomes a phone idle state (33).

The present invention described above is capable of various substitutions, modifications, and changes without departing from the technical spirit of the present invention for those skilled in the art to which the present invention pertains. It is not limited by the drawings.

As described above, the present invention relates to a PDSN PPP inactivity timer and a PDSN PPP session timer when a wireless communication terminal is connected to a packet data service node (PDSN) to access a WAP. When the time elapsed in step 1) has elapsed, there is an effect of terminating a WAP connection by terminating a Point-to-Point Protocol (PPP) connected to the PDSN network according to a PDSN PPP session timer.

That is, according to the present invention, if the user does not terminate the WAP, the communication with the packet data service node (PDSN) takes a lot of load and consumes a lot of battery. Therefore, the user does not terminate the WAP. In this case, when it is not used for a certain time, the swap connection is terminated according to the swap session timer (PDSN PPP session timer), thereby preventing unnecessary communication.
