Description

  The present invention relates to a disconnection sequence technique when a terminal belonging to a network performs a power-off process during data communication.

  High-speed data communication is realized as one terminal on a network with a wireless communication terminal such as a mobile phone.

  In a new mobile phone network system recently implemented in Japan and the like, a terminal is requested to receive a net address from the network, so that a unique network address is given, whereby a session is opened and a session negotiation process is performed.

  Therefore, even when data communication is not being performed, if the user connects to data communication in this state, it is not necessary to perform session open processing or session negotiation processing. Stand by.

  At the time of data communication connection, a data communication connection request is transmitted to the network, a data communication channel is assigned from the network side, and data communication is started.

  However, it may be necessary to turn off the power of the terminal during data communication (for example, when the user enters a cell phone use prohibited area while moving and the user turns off the power of the mobile phone). ). At this time, in the cellular phone network as described above, a communication disconnection request event and a power disconnection request event occur simultaneously.

  At this time, regarding the communication disconnection request event, in the above-described network, the wireless communication disconnection process is executed by the communication disconnection request event. In this case, the network address used so far is released, and the standard determines that the mobile phone shifts to the next new network address acquisition operation for the next standby operation.

  At this time, in the above-mentioned network in which the power-off process operates in parallel processing, the power of the mobile phone is cut off during the communication disconnection process or the subsequent address acquisition process depending on the timing of the power-off process. The cutting process sequence ends in the middle.

  In addition, as a related patent document, while performing an end-of-call operation by operating a power switch, the end-of-call method of a wireless telephone device that cuts off the power supply by delaying the time required for the end-of-call operation by a timing method, It is disclosed in Patent Document 1.

Japanese Patent Publication No. 5-35932

  As described above, in a wireless communication terminal that obtains a network address from a network and performs data communication, when a power-off event occurs while the terminal and the network are communicating, acquisition of a new network address during or after the communication disconnection process In the middle of processing, the terminal is powered off, and the communication disconnection processing sequence ends in the middle.

  In this case, if the communication disconnect message does not reach the network, the terminal disconnects while the network is still in a state where the communication status does not match the status of the terminal and the network, the network continues to send useless data, or after the terminal disconnects the network A new network address is requested, but a new problem occurs such that an address assignment message from a subsequent network cannot be received. At this time, if a new network address acquisition process for the next network connection is performed first, it takes time until the terminal power is turned off.

  In the call termination method of the radio telephone apparatus described in the above-mentioned Patent Document 1, the power is turned off after the call termination operation is performed by operating the power switch, and the network address is obtained from the network to perform data communication. The wireless communication terminal that performs network address acquisition processing for the next network connection after communication disconnection has not been touched, and the time until power off or the next power on at the time of power off request during data communication There is no mention of network connection time.

  An object of the present invention is to perform a data communication by acquiring a network address from a network and perform a network address acquisition process for the next network connection after the communication is disconnected. It is an object of the present invention to provide a network disconnection method for a wireless communication terminal that eliminates inconsistency between a communication terminal and a network and shortens the time until power is turned off or the network connection time at the next power-on.

  In order to solve the above-described problem, the present invention performs data communication in a wireless communication terminal that acquires a network address from a network and performs data communication, and performs a new network address acquisition process for the next network connection after disconnection. When a power-off request is issued, a terminal power-off request is issued, a terminal power-off process suspension timer is started, a communication disconnection request is issued to the network, and a disconnection response from the network is determined to be disconnected. If there is a response, determine whether to issue the terminal power-off request, if it is issued, clear the time setting by the terminal power-off process pause timer, stop the new network address acquisition process, A power-off process is performed.

  As a result, when a power-off event occurs during data communication between the wireless communication terminal and the network, the communication sequence is correctly processed, and the state mismatch between the wireless communication terminal and the network at the time of terminal power-off during communication is resolved. In addition, an unnecessary communication load exchanged on the wireless network is reduced, and further, at this time, a network address acquisition process for the next connection is performed. By stopping the process, the power-off time can be shortened.

  The present invention also provides a wireless communication terminal that acquires a network address from a network to perform data communication, and performs a new network address acquisition process for the next network connection after the communication is disconnected. Issuing a power-off request, starting a terminal power-off process temporary stop timer, issuing a communication disconnection request to the network, determining whether there is a disconnection response from the network, Performs new network address acquisition processing, then determines whether negotiation is incomplete, transitions to standby when negotiation is complete, then determines whether or not the terminal power-off request is issued, and disconnects the terminal power when it is issued Clear the time set by the processing pause timer and Scan acquisition process the Stop, characterized in that the power-off process.

  As a result, when a power-off event occurs during data communication between the wireless communication terminal and the network, the communication sequence is correctly processed, and the state mismatch between the wireless communication terminal and the network at the time of terminal power-off during communication is resolved. Reduces unnecessary communication load exchanged over the wireless network, and when a power-off event occurs, the power-off is paused until a new network address is obtained for the next network connection. The network connection time at the time of input can be shortened.

  According to the present invention, in a wireless communication terminal that acquires a network address from a network to perform data communication and performs a network address acquisition process for the next network connection after the communication is disconnected, It is possible to obtain a network disconnection method for a wireless communication terminal that eliminates a mismatch between the communication terminal and the network and shortens the time until the power is turned off or the network connection time at the next power-on.

  Hereinafter, a first embodiment of the present invention will be described with reference to FIGS. 1 and 2.

  First, FIG. 1 is a diagram showing a sequence when the wireless communication terminal according to the first embodiment of the present invention receives a power-off request during data communication.

  The terminal 101 is a communication portable terminal such as a mobile phone, a PDA equipped with a wireless network function, or a notebook PC. The network 102 is a network constructed by a mobile phone base station or other equipment, or a wireless network constructed in a company or home. The terminal 101 and the network 102 have a communication protocol with each other and establish a network.

  The terminal 101 acquires a network address from the network 102 to perform data communication, and performs a new network address acquisition process for the next network connection after the communication is disconnected.

  Therefore, the terminal 101 first makes a network address acquisition request to the network 102, and the network 102 assigns a unique network address to the terminal when the terminal 101 is allowed to participate in the network. When the network address is assigned, the terminal 101 and the network 102 are in a standby state, and when a communication connection request is made from the terminal 101 or the network 102, a data communication channel is assigned and data communication is performed. Will be started. A state in which data is exchanged on the data communication channel and data communication is being performed is during communication 103.

  In the state of 103 during communication, if there is a power-off request 104 such that the terminal user turns off the power of the terminal 101 due to pressing of the power key or for some reason, the terminal 101 sends a request to the network 102 via wireless communication. A communication disconnection request S11 is transmitted. At this time, while the communication protocol is performing the communication disconnection sequence, the power-off processing of the terminal 101 is performed, the power supply is not lost, and the power-off pause 105 processing is performed to prevent the communication protocol from operating normally. .

  When the disconnection response S12 to the communication disconnection request S11 is received from the network 102, the power disconnection suspension 105 is stopped. At this stage, the terminal 101 and the network 102 are in a state 106 in which the network session is released by mutual communication disconnection processing.

  At this time, the network address used so far is released. In this case, the process of acquiring a new network address for the network 102 is not performed (107). Thereafter, the terminal power-off process 108 is performed. At this time, the new network address acquisition process stop 107 does not disconnect the power in the middle of the new network address acquisition process sequence, and the normal communication disconnection sequence between the terminal 101 and the network 102 is performed. In addition, there is an effect of shortening the power-off time.

  Next, FIG. 2 is a diagram showing a processing flow inside the terminal 101 for realizing the sequence of FIG.

  When a terminal power-off request 201 is generated due to a terminal user's power-off operation or the like in the state of being in communication 103, a communication power-off request issuance 202 process to the network 102 is performed, and at the same time, a terminal power-off request issuance 209 is issued. Then, the terminal power-off process temporary stop timer is started (210). The reason why the timer 210 is activated is that the communication disconnection request S11 and the disconnection response S12 are wireless communications. Therefore, the communication disconnection request S11 and the disconnection response S12 may not arrive in an environment where radio waves are bad. This is so that even if it does not reach, it can be shifted to the power-off process when the timer expires.

  The communication protocol that has received the communication disconnection request issuance 202 to the network 102 performs a communication disconnection request transmission 203 to the network 102, transmits a communication disconnection request S11, waits for a disconnection response S12 from the network 102, and Processing for determining whether or not a disconnection response S12 has been received is performed (204).

  When the disconnection response S12 is received from the network 102, the presence / absence of the terminal power disconnection request issuance 209 is determined (211). This is because when there is no terminal power-off request issuance 209, it is a communication disconnection request during normal communication, and in this case, a new network address acquisition process 212 is performed and the process proceeds to the standby 213 process.

  When there is a terminal power disconnection request issuance 209 in the determination 211, and in the process (204) for determining whether or not the disconnection response S12 has been received, if there is no disconnection response, the determination of the presence / absence of the disconnection response is repeated, and the set time by the timer When the lapse of time has elapsed, the terminal power-off process temporary stop timer started at 210 is cleared (206). Then, a new network address acquisition process stop 207 is performed. As a result, the power is not cut off during the new network address acquisition processing sequence, and the power-off time can be shortened. Thereafter, terminal power-off processing 208 is performed.

  In addition, when the terminal 101 moves to a place where power-off is not required, it may be possible to change the communication network and acquire a new network address. At this time, when acquiring a new network address In addition, since the network address that has been used up to now is released, it does not take time for the processing to be released, and the time for acquiring a new network address is shortened.

  Hereinafter, a second embodiment of the present invention will be described with reference to FIGS.

  First, FIG. 3 is a diagram showing a sequence when the wireless communication terminal according to the second embodiment of the present invention receives a power-off request during data communication.

  The terminal 301 is a mobile communication terminal such as a mobile phone terminal, a PDA equipped with a wireless network function, or a notebook PC terminal. The network 302 is a network constructed by a mobile phone base station or other devices, or a wireless network constructed in a company or home. The terminal 301 and the network 302 have a communication protocol with each other and establish a network.

The terminal 301 acquires a network address from the network 302 and performs data communication. After the communication is disconnected, the terminal 301 performs a new network address acquisition process for the next network connection. Therefore, the terminal 301 first sends a network address acquisition request to the network 302. The network 302 assigns a unique network address to the terminal 301 when the terminal 301 is allowed to participate in the network. When the network address is assigned, the terminal 301 and the network 302 are in a standby state, and when a communication connection request is made from the terminal 301 or the network 302, a data communication channel is assigned, and data communication is performed. Will be started. A state in which data is exchanged on the data communication channel and data communication is being performed is during communication 303.

  In the state of communication 303, if there is a power-off request 304 that causes the terminal user to turn off the power of the terminal 301 due to pressing of the power key or for some reason, the terminal 301 sends a request to the network 302 via wireless communication. A communication disconnection request S11 is transmitted. At this time, while the communication protocol is performing the communication disconnection sequence, the power-off processing of the terminal is performed, the power supply is not lost, and the power-off temporary stop 305 processing is performed to prevent the communication protocol from operating normally.

  When the disconnection response S32 to the communication disconnection request S31 is received from the network 302, the power disconnection suspension 105 is stopped. At this stage, the terminal 301 and the network 302 enter a state 306 in which the network session is released by the communication disconnection process. At this time, the network address used so far is released.

  Thereafter, a new network address acquisition request S33 is made to the network 302 in preparation for the next network connection. An address assignment S34 comes from the network 302, and a negotiation S35 is performed to shift to a standby state. As a result, a new network address is assigned inside the terminal 301, and a standby state can be established immediately. Further, inside the network 302, a network address is assigned to the terminal 301, and a standby state 308 is opened in which a session is opened. In this state, the terminal power-off process 307 is performed.

  During this time, the power-off suspension process 305 operates, so that the power is not cut off during the new network address acquisition process sequence, and a normal communication disconnection sequence is performed between the terminal 301 and the network 302. Further, since the new network address is acquired before the power is turned off, there is an effect of shortening the connection time to the network 302 when the power is turned on again.

  Next, FIG. 4 is a diagram showing a processing flow inside the terminal 301 for realizing the sequence of FIG.

  When a terminal power-off request 401 is generated by a terminal user's power-off operation or the like in the state of communication 303, a communication power-off request issuance 402 processing to the network 102 is performed and a terminal power-off request issuance 408 is issued at the same time. Then, the terminal power-off process temporary stop timer is started (409). The reason why the timer 409 is activated is that the communication disconnection request S31 and the disconnection response S32 are wireless communication, and in an environment where radio waves are bad, the communication disconnection request S31 and the disconnection response S32 may not arrive. This is so that even if it does not reach, it can be shifted to the power-off process when the timer expires.

  The communication protocol that has received the communication disconnection request issuance 402 from the network 302 sends a communication disconnection request transmission 403 to the network 302, transmits a communication disconnection request S31, waits for a disconnection response S32 from the network 302, and Processing for determining whether or not a disconnection response S32 has been received is performed (404).

  When a disconnection response S32 is received from the network 302, a new network address acquisition process 410 for acquiring a new network address is performed. Thereafter, when the negotiation is completed in the negotiation completion determination 411, the terminal 301 shifts to the standby state 413.

  Here, the terminal 301 determines whether or not there is a terminal power-off request issuance 408 (414). This is because when there is no terminal power-off request issuance 408, it is a communication disconnection request during normal communication, so that the standby 415 is continued as it is.

  If the disconnection response from the network 302 and the completion of the negotiation are not completed by the expiration of the terminal power supply disconnection process pause timer (405, 412), it is determined that the radio wave is in a bad environment and the terminal power supply disconnection process pause timer clear process 406 is performed. The terminal power-off process 407 is performed. As a result, the power is not cut off in the middle of the new network address acquisition processing sequence, and there is no inconsistency between the state of the terminal 401 and the network 402, and there is an effect of shortening the next communication connection time.

  Each embodiment of the present invention described above is an example for explaining the present invention, and is not intended to limit the scope of the present invention only to the embodiment. Those skilled in the art can implement the present invention in various other modes without departing from the gist of the present invention.
