[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a timer control method and device suitable for use in, for example, a mobile phone device.

[0002]

2. Description of the Related Art For example, in a portable telephone device, a large number of timers are used in call protocols such as calling and receiving calls. That is, for example, in a call protocol, for example, when making a call, a timer T1 (30 seconds) for measuring the waiting time after the connection request from the base station side or the response of connection refusal is received after the call request signal is transmitted. ) Is provided. Therefore, if these answers are not obtained during this period, the call request process is performed again.

In addition, when ending a call, a timer T2 (3) for measuring the waiting time after the call end request signal is transmitted and before the end confirmation or refusal from the base station is obtained.
0 seconds) is provided. Further, when the communication is ended, a timer T3 (30 seconds) is provided for measuring the waiting time after the signal for requesting the end of communication is transmitted until the end confirmation or the reply of refusal is obtained from the base station side. Therefore, if each answer is not obtained during this period, the processing of the call or communication end request is performed again.

On the other hand, for example, when a signal for connection processing is received from the base station side after requesting a call, waiting for obtaining a ringing tone from the base station side to the called side or a signal for other processing. A timer T4 (30 seconds) for counting time is provided.
Therefore, if the signal of any processing from the base station side is not obtained during this period, the processing from the transmission of the signal of the first call request is performed again, or the normal internal processing operation is performed. is there.

Further, when a call is started at the time of an incoming call, a timer T5 (30 seconds) is provided for measuring the waiting time until the connection confirmation signal from the base station is obtained after the connection request signal is transmitted. ing. In addition, when changing the communication specifications by facsimile communication, etc., a timer T6 (30 seconds) for measuring the waiting time after the change request signal is transmitted until the change confirmation or the refusal response from the base station is obtained is provided. It is provided.
Therefore, if each answer is not obtained during these periods,
The processing of these requests is performed again.

Further, when a dial signal is generated by a so-called dual tone when a call is made, a timer T7 (200) for controlling the generation period of the dual tone is used.
msec) and a timer T8 (20 for controlling the stop period)
0 ms) is provided. Therefore, these timers T7
By using T8 and T8, it is possible to favorably generate a dial signal by dual tone, for example.

[0007]

That is, in the above description, for example, eight timers are required in the call protocol. On the other hand, the specifications of the mobile phone device stipulate that up to five calls can be processed at the same time, and if eight timers are required in the above-mentioned one-call protocol, the entire 8 × 5 = 4
Zero timers would be required.

By the way, when such a large number of timers are used in the apparatus, for example, a clock whose value is incremented every predetermined time (10 msec) is used, and when each timer is activated The value obtained by adding the value of the timer set to the value is stored, and the elapse of the timer time is determined when the added value and the value of the clock match. Therefore, each timer is given an ID, the added value is stored for each ID, and when the elapse of the timer time is determined,
Notification is made with this ID.

However, in such a timer, the judgment of the elapse of the timer time is made with respect to the added value stored in all the IDs at every predetermined time (10 msec) in which the value of the clock is increased. It must be made. Therefore, there is a limit to the number of timers that can make such a judgment, and for example, the number of timers is 128 in the apparatus to which the present invention is applied. Therefore, considering that timers are used in other processes, it is problematic to occupy as many as 40 timers with only the above call protocol.

This application has been made in view of such a point, and the problem to be solved is that the number of timers used in the device is limited, and for example, only a specific protocol is available. There is a problem in occupying a large number of timers.

[0011]

Therefore, in the present invention, the same ID is assigned to a plurality of timers that do not operate simultaneously in a series of processing, and the name of the request source of the timer is set when the timer is started. The parameter including the parameter is supplied to the timer means, and the notification when the timer value has elapsed is sent to the request source of the timer indicated by the parameter. According to this, one timer processes a plurality of timers. And the number of timers used can be significantly reduced.

[0012]

Therefore, when making a call, for example, in the microcomputer 9, the processing is performed as shown in FIG. 2, for example. That is, in FIG. 2, first, the CC task is inactive. When the call request from the MMI task is supplied to the CC task in this state, the C task
Control is performed from the C task to the transmission / reception circuit 4 to transmit a signal of a connection request to the base station. Further, the CC task issues an activation function [T1] for activating the above-mentioned timer T1 to the TT task.

Further, in the CC task, when the transmission / reception circuit 4 receives a connection establishment signal from the base station, the transmission / reception circuit 4 is controlled to transmit a call request signal to the base station. When the transmission / reception circuit 4 receives a signal for connection processing from the base station, the stop function [T for stopping the above-mentioned timer T1 from the CC task to the TT task is received.
1] is issued.

Further, the CC task notifies the MMI task of the start of the connection process. At the same time, the CC task issues to the TT task an activation function [T4] for activating the timer T4. When the transmitting / receiving circuit 4 receives the ringing tone signal from the base station to the receiving side, the above-mentioned timer T is sent from the CC task to the TT task.
A stop function [T4] for stopping 4 is issued. In addition, the CC task notifies the MMI task that it is calling.

Further, when the transmission / reception circuit 4 receives a connection signal from the base station, the CC task controls the transmission / reception circuit 4 to transmit a connection confirmation signal to the base station. Then, the CC task notifies the MMI task of the start of the call, and the call is started.

Further, in FIG. 2, the starting function [T1]
From the issuance of the stop function [T1] to the issuance of the start function [T4] to the issuance of the stop function [T4] of the TT task. When the progress of is judged, the progress notification [T1] or [T4] is issued from the TT task to the CC task. In this case, in the CC task, the operation from the time when the call request from the first MMI task is supplied to the CC task is performed again.

Further, in the microcomputer 9 described above, for example, when receiving an incoming call, the processing is performed as shown in FIG. 3, for example. That is, in FIG. 3, first, the CC task is inactive. In this state, when the transmission / reception circuit 4 supplies an incoming call signal from the base station to the CC task, the CC task notifies the MMI task of the incoming call.
When the MMI task returns confirmation of the incoming call, CC
The task controls the transmission / reception circuit 4 to transmit an incoming call confirmation signal to the base station.

When the MMI task reports that a ringing tone is generated, the CC task controls the transmitting / receiving circuit 4 to transmit a ringing tone signal to the base station. Further MM
When the response start is reported from the I task, the CC task controls the transmission / reception circuit 4 to transmit a response notification signal to the base station. At the same time, the CC task issues to the TT task an activation function [T5] for activating the timer T5.

When the transmission / reception circuit 4 receives the signal for confirming the response notification from the base station, the CC task issues a stop function [T5] to the TT task to stop the timer T5. . From CC task to MMI
The task is notified that the call is started, and the call is started.

If the TT task determines that the time of the timer value has elapsed between the issuance of the start function [T5] and the issuance of the stop function [T5], the TT task transits to the CC task. [T5] is issued. In this case, in the CC task, the operation from the time when the response start is reported from the MMI task is performed again.

In this way, processing for making a call and a call is performed, for example. Then, in these processing and other processing, the above-mentioned starting function [Tn] (n = 1 to 8)
Is the ID value of the timer used, the respective timer value,
It is composed of an input port name of a task (CC) requesting a timer, a start address of a message described later, and the like.
Therefore, in order to form this activation function [Tn], the CC task has a part of its work area, for example, as shown in FIG.
A table as shown in A of FIG.

That is, in FIG. 4A, a table is provided for each of the above-mentioned timers T1 to T8, and the ID value of each timer used, the timer value (in milliseconds), and the formation of each message described later. The serial number that is incremented to is written. In this case, the ID values of the timers used are the same for the timers T1 to T6. Also, as the timer value, a required value is written in milliseconds.

On the other hand, in the TT task, a table as shown in FIG. 4B, for example, is provided in a part of the work area of the memory. That is, in FIG. 4B, a status value indicating use / non-use, a set timer elapsed time, a port name of a request source task, and a start address of a message described later are written for each timer ID.

Using these tables, the above-mentioned activation function [Tn] is issued, for example, as shown in A of FIG. That is, in A of FIG. 5, first, in step [1], T indicated by the timer ID value of the timer Tn.
The timer ID of the T task is reset. Next, in step [2], the status value of the timer ID is set to indicate that it is in use.

Further, in step [3], a message area as shown in C of FIG. 4 is secured in a part of the work area of the memory of the CC task. Then, in step [4], the timer name [Tn] is added to this message area.
Then, the source task (timer task in this case) and the data length (= 0) are written.

Further, in step [5], the above-mentioned timer T1
The serial number of the table of T8 to T8 is incremented by "+1", and this value is written in the serial number of the table of T1 to T8. Further, in step [6], the serial number and the name indicating any one of the above-mentioned five defined calls are written in the above-mentioned message area.

Then, in step [7], the above-mentioned timer T
ID values of the timer written in the tables 1 to T8,
A start-up function [Tn] is formed by the timer value, the input / output port name of this CC task, and the start address of the secured message area described above.
Is issued to the TT task.

Therefore, in the TT task which has received this activation function [Tn], the time of the timer set in the table of the timer specified by the ID value in the function (the current time value of the timer value in the function Formed by adding 1/10)
And the input / output port name in the function and the address of the beginning of the message area are written. As a result, in the TT task, the above-mentioned timers T1 to T8 are started by the timer having the ID value written in the table.

The above-mentioned stop function [Tn] is issued, for example, as shown in B of FIG. That is, FIG.
B, first, in step [11], the status value of the timer ID of the TT task indicated by the timer ID value of the timer Tn is set to indicate non-use.

Next, at step [12], the above-mentioned timer T
A stop function [Tn] is formed by the ID values of the timers written in the tables 1 to T8.
n] is issued to the TT task. Further steps [1
In 3], the message area secured in a part of the work area of the memory of the CC task is released.

Therefore, the TT task receiving this stop function [Tn] releases the table of the timer designated by the ID value in the function. By this, the above-mentioned timer T1
~ The timer of the ID value written in the table of T8 is stopped.

On the other hand, when the elapse of the set timer time is determined, the TT task notifies the CC task of the elapse of time. And in this case,
Notification of the passage of time is sent to the input / output port specified by the function.
It is performed by sending the start address of the message area specified by the function.

As a result, the CC task determines that the time of the timer having the timer name [Tn] written in the message area has elapsed. In this case, the stop function [T
[n] is not issued by mistake, or even when a notification of the passage of time is made by mistake due to a timing error or the like, the error is determined by the mismatch of the serial numbers.
Malfunction can be avoided.

Therefore, in this apparatus, the same ID is given to a plurality of timers that do not operate simultaneously in a series of processes, and a parameter including the name of the request source of the timer is supplied to the timer means when the timer is started. , The notification when the timer value has passed can be sent to the requester of the timer indicated in the parameter.

As a result, according to the present invention, the number of timers used in the apparatus is conventionally limited, and there is a problem in occupying a large number of timers only with a specific protocol. A plurality of timers can be processed by one timer, and the number of timers used can be significantly reduced.

That is, for example, in the above-mentioned call protocol, eight timers are conventionally required in one call protocol, and 8 × 5 is provided for the prescribed five calls.
= 40 timers are required, but in the above embodiment, the timers T1 to T6 are also used as one timer, and the timers T7 and T8 can be commonly used for five calls. Therefore, 1 × 5 + 2 = 7 as a whole
Each timer can process the prescribed 5 call protocols.

Thus, according to the above-described timer control method and apparatus, the same ID is given to a plurality of timers that do not operate simultaneously among the timers used during a series of processing, and an arbitrary timer is given. A parameter including at least the same ID value, a variable timer value, and the name of the request source of the timer is supplied to the single timer means indicated by the ID when the timer is started, and the timer indicated by the name when the timer value has elapsed. By notifying the requester of the above, one timer can process a plurality of timers, and the number of timers used can be significantly reduced.

In the above timer control method and apparatus, the timer values set in the timers T1 to T6 may not be the same. Further, the application of the above-mentioned timer control method and device is not limited to the above-mentioned mobile phone device, and in any process, a plurality of timers that do not operate simultaneously among the timers used during a series of processes. Is applicable to.

[0044]
