Abstract

PURPOSE:To enhance the success probability of automatic redialing and to allow the user to confirm the reception of an interrupting message by applying automatic redial processing when re-request message is received after dial processing and restoring the state to the initial state when the interrupting message is received. CONSTITUTION:A control circuit 10 comprising an 8-bit microprocessor sends and receives a data message to control each device in a radio communication equipment via a data reception circuit 5 and a data transmission circuit 6. When a re-request message is received after the dialing processing, it is informed and the initial state is restored. Thus, the success probability of automatic redialing is increased and the user recognizes the reception of the interrupted message.

(B) Conventional technology Conventionally, in a cellular communication system, a baseband data signal (forward control channel message) is transmitted from a radio base station to perform control such as channel change, and received by a radio communication device. To perform each process. Meanwhile, a re-request (Reorder) message and an interruption (Intercept) message are carried on this baseband data signal.
Here, the re-request message informs the user that all the lines are in use and the call sent by the user must be re-originated. The suspend message is used to notify a user that a procedure error has occurred when a call is activated. Incidentally, there are the following cases as what is called a procedure error.

(2) When the electric serial number (transmitted to the base station at the time of calling) is in an error state due to a device failure. For example, the wireless communication device disclosed in Japanese Patent Application Laid-Open No. 63-180231 Generally, when a re-request message is received, an automatic re-call is performed as disclosed in Japanese Patent Publication No. 58-36869. Further, the interruption message is handled in the same manner as the re-request message, and an automatic re-call is performed.

(C) Problems to be Solved by the Invention However, the case where the interruption message is transmitted is as described above, and even if an automatic recall is performed, it is not accepted. Therefore, the user is perceived as having a very low probability of success of the automatic repeat call, which in turn gives the user distrust of the system.

FIG. 3 is a flowchart showing a program of a main part of the control circuit (10), and the operation will be described based on the flowchart. First, after the control circuit (10) performs an initial setting (step S-1), when the user performs a call operation for a call applicant using a predetermined key, the control circuit (10) searches for a control channel. Then, it is determined whether or not the area is a service area (steps S-2 and S3).
And, if the control circuit (10) is not a service area,
"NO SERVICE" is displayed on the display (7) for a predetermined time, and an intermittent sound is generated by the buzzer (8) for the same time as this display, and the process returns to step S-2 (step S-17). In the service area, the forward control channel message in the cell is read through the data receiving circuit (5),
Detect the state of the blank-occupied bit (step S-
4, 5). Here, if the reverse control channel is occupied, the processing of steps S-3 to S-5 is performed again every 5 seconds, and if the state does not change ten times, the indication of "busy" is displayed on the display (7). Is performed for a predetermined time, and an intermittent sound is generated by the buzzer (8) for the same time as this display.
The process returns to -2 (steps S-14 to S-17). If the reverse control channel is available, the initial setting is reset again, and a call message (including the electric serial number) is transmitted through the data transmission circuit (6) (steps S-6 and S7). Thereafter, an interruption message is sent from the radio base station based on a predetermined cause. When the interruption message is read by the control circuit (10) via the data receiving circuit (5), the display unit (7) immediately displays "intercept". Is displayed for a predetermined time, and a buzzer (8)
Causes the intermittent sound to be generated for the same time as this display, and returns to step S-2 (steps S-8 and S17). Also, a re-request message is sent from the radio base station based on a predetermined cause,
When this is read by the control circuit (10) via the data receiving circuit (5), the processing of steps S-3 to S-9 is repeated every 5 seconds. When a re-request message is transmitted, "reorder" is displayed on the display (7) for a predetermined time, and a buzzer (8) generates an intermittent sound for the same time as this display.
The process returns to -2 (steps S-14 to S-17). Next, when there is no transmission of the interruption message and the re-request message, the initial setting is reset again (Swipe S-10), and the confirmation message (including the instruction of the voice channel is included within a predetermined time after the transmission of the calling message). ) Is not sent from the radio base station, the call message is not correctly given to the radio base station, and thus, in this case, step S is performed every 5 seconds.
-3 to 11 are repeated 10 times (step S
-14 to 16).
