Abstract

PROBLEM TO BE SOLVED: To improve the reliability of data communication by informing a radio communication disable notice in the case that radio communication is disable, reporting a radio communication restart notice in the case that radio communication is able to be restarted and restarting the data communication to attain the communication without caring about deterioration in radio transmission environment. SOLUTION: A radio communication means 101 makes data communication through a radio channel and provides an output of a communication result, but in the case of occurrence of a communication error on the way of data communication, the means 101 activates a radio communication disable notice means 102. A communication time generating means 13 that receiving a radio communication disable notice generates a signal as to when the radio communication is to be restarted. When the radio communication restart time comes, the communication time generating means 103 allows a communication restart propriety check means 104 to provide an output of a check result. In the case that restart of radio communication is possible, a radio communication restart notice means 106 is activated and a radio communication restart notice signal is generated, and a radio communication restart instruction means 107 instructs restart of the data communication to the radio communication means 101.

If the output of step 202 indicates normal termination, the data communication has terminated normally, and the process is terminated. The communication timing generation unit 103 that has received the wireless communication disable notification in step 203 generates a signal as to when (for example, 20 minutes later) wireless communication is to be resumed (step 204). The method of generating the restart timing differs depending on the environment of the wireless transmission path when the communication timing generator 103 is being executed. If the environment of the wireless transmission path is good when the communication timing generation unit 103 is being executed, the communication timing generation unit 103 determines that the communication can be resumed immediately, and minimizes the restart of the wireless communication. Generate so that it can be restarted in time. If the environment of the wireless transmission path is poor while the communication timing generation means 103 is being executed, the communication timing generation means 103 delays the wireless communication restart time (for example, after 5 minutes). I do. In addition, the resumption timing may use the resumption timing set by the user.

The communication timing generation means 103 performs setting for enabling the communication resumption permission / inhibition checking means 104 to execute when it is time to restart the wireless communication (step 205). If it is time to restart the wireless communication, the communication restartability checking means 104 is executed in step 205 to check whether the wireless communication can be restarted (step 206). Since it is necessary to know the state of the wireless transmission path for the inspection, the communication resumability checking unit 104 calls the wireless status obtaining unit 105, and the called wireless status obtaining unit 105 checks the wireless environment. The state is returned to the communication resumability check means 104 (step 207), and the communication resumability check means 104 receiving the reply outputs a state indicating whether wireless communication can be restarted (step 208).

When the time has elapsed and time t2 (506) is reached, the wireless state becomes poor (502), the wireless communication of wireless communication means 101 is interrupted at time t3 (507), and wireless communication means 101 The refusal notification unit 102 is called. The called wireless communication disable notification means 102 notifies the communication timing generation means 103 that the wireless communication has been interrupted. Communication timing generation means 103
Calculates the restart time at time t4 (508). The wireless environment at time t4 (508) is good (503)
Therefore, the next restart time is generated in the minimum time (50
9).

In this operation example, the time t5 is set as the restart time.
(410) was generated. Next, after the resumption time has elapsed, a call is prepared so that the next process is called (509). At time t5 (510), which is the restart time, the communication restart permission / inhibition checking unit 104 determines whether wireless communication can be restarted (511). Here, the communication restart availability check unit 104 checks the current wireless environment using the wireless status acquisition unit 105.

In this operation example, at time t5 (510), the wireless environment is good (503), so the wireless status acquisition means 105 outputs a good wireless environment. The communication resumability checking means 104 receives the output, determines that the wireless communication can be restarted, and calls the wireless communication restart notifying means 106. The wireless communication restart notifying unit (106) sends a restart notification to the wireless communication restart instructing unit 107, and the wireless communication restart instructing unit 107 that has received the restart notification instructs the wireless communication unit 101 to perform wireless communication. Upon receiving the instruction, the wireless communication unit 101 performs wireless communication and is in wireless communication (513). Time t6 in this example indicates that the wireless communication is continued even after time t6 has elapsed after the restart of the wireless communication. The operation of one embodiment of the present invention has been described above in detail with reference to the drawings. However, the present invention is not limited to this embodiment, and there are design changes and the like that do not depart from the gist of the present invention. Are also included in the present invention.

As described above, according to the present invention, in the transmission and reception of data in a wireless environment, even if the wireless environment is deteriorated and the wireless communication is interrupted and the wireless environment is restored, the wireless communication is automatically restarted. However, since the communication is automatically continued until all the data transmission / reception is completed, there is an effect that the data transmission / reception can be performed without worrying about the wireless environment. In addition, since data transmission / reception is completed irrespective of the wireless environment, the effect of improving the reliability of data transmission / reception in a wireless environment is obtained.
