ABSTRACT:
CROSS REFERENCE TO RELATED APPLICATIONS
The present invention claims priority from Japanese Patent Application No. 11-336727 filed Nov. 26, 1999, the contents of which are incorporated herein by reference.
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to an incoming notification pattern setting circuit and method of a portable telephone constructed so that a user can provide incoming notification by various lighting color patterns in a portable telephone apparatus.
2. Description of Related Art
In a portable telephone apparatus, it is necessary to notify a user that incoming has occurred, and for that purpose, incoming notification means constructed so that the user recognizes the incoming through senses of sight, hearing, tough (vibration), etc. is provided.
As functions of the incoming notification means of a portable telephone, the ability to perform incoming notification by characteristic patterns for the purpose of differentiating among other users in the incoming notification to express originality other than the purpose of recognizing an originator has been required.
As such incoming notification means, in recent years, the incoming notification means providing a function of creating a ringing tone (melody) on user's own to set it as one method of expressing originality as well as recognizing an originator has become the mainstream, but the incoming notification by the ringing tone is not necessarily a preferable method since surrounding people may feel like noise and be troubled. Incidentally, the function may make the setting every partner registered in a telephone book.
As means capable of avoiding such a problem, incoming notification means by a method of expression except a tone has been desired, and a method constructed so that color or display patterns of a light emitting diode (LED) for incoming notification or vibration patterns of a vibrator for incoming notification can be set by selecting the pattern from several kinds of patterns previously prepared within the portable telephone apparatus has been known conventionally.
An incoming notification pattern setting technique of a conventional portable telephone will be described below.

is a block diagram showing a configuration example of a portable telephone apparatus capable of setting incoming notification patterns to which the conventional art and the present invention are applied, and
FIG. 10
is a block diagram showing a configuration example of an incoming notification pattern setting circuit of a conventional portable telephone.
As shown in
FIG. 9
, the portable telephone apparatus capable of setting incoming notification patterns generally comprises an antenna
101
, a wireless send/receive part
102
, a signal processing part
103
, a notification device driving part
104
, and a control part
105
.
The antenna
101
sends and receives wireless signals (radio waves) between the antenna and a base station (not shown). The wireless send/receive part
102
receives a phase-modulated high-frequency signal from the base station received through the antenna
101
to demodulate the signal and reproduces audio signals or control data, and also generates a phase-modulated wave by audio signals from the signal processing part
103
or control data from the control part
105
to amplify the wave and sends out it to the antenna
101
. The signal processing part
103
comprises a digital signal processor (DSP) etc. and performs processing of compressing audio signals inputted from a microphone
111
and outputting the signals to the wireless send/receive part
102
and performs processing of expanding the received audio signals and outputting the signals to a receiver
112
. The notification device driving part
104
, which is a member for driving various equipment for incoming notification, provides incoming notification by sound using a sounder
121
and provides incoming notification by light using an LED
122
and provides incoming notification by vibration using a vibrator
123
.
The control part
105
, which is a member for performing control of each part of the apparatus, detects a call number to a local apparatus from data of a predetermined position in a demodulation signal of the wireless send/receive part
102
and provides incoming notification in the notification device driving part
104
by matching the call number with the number of the local apparatus held in ID memory
131
, and also implements processing of data for control to be sent and received, mail send/receive processing and a server connection function. Also, the control part
105
has read only memory (ROM)
132
for storing operational programs of a central processing unit (CPU) within the control part
105
and fixed data, and random access memory (RAM)
133
for holding temporary data in the case of operation of the CPU. A key input part
134
is used for inputting a caller ID, registration of a telephone book or setting of various functions to the control part
105
. A display part
135
displays telephone number on incoming and outgoing or setting of various functions interlocked with the key input part
134
. Further, the control part
105
normally has an external connector
136
made of a 16-core connector and is connected to an external device through a special cable and conducts data communications with the external device using a start-stop synchronous function
141
within the control part
105
. Also, the control part
105
normally includes time means such as a timer
142
.
As shown in
FIG. 10
, the incoming notification pattern setting circuit of the portable telephone of the conventional art comprises a CPU
201
, ROM
202
, RAM
203
, ID-ROM
204
, an output port register
205
, an LED driver
206
, and a plurality of LEDs
207
.
The CPU
201
operates based on programs stored in the ROM
202
and checks number information in control data in the received signal from the wireless send/receive part
102
with data of a call number of a local apparatus held in the ID-ROM
204
and when a call to the local apparatus is detected, the output port register
205
is controlled directly by outputting a write signal and data previously held in the RAM
203
is read out and is once held in the output port register
205
through an address/data bus and thereafter, by outputting the data to the LED driver
206
, the LED driver
206
provides incoming notification by light in the LEDs
207
by controlling the LEDs
207
based on this data.
However, in the incoming notification pattern setting technique of the conventional portable telephone, incoming notification patterns capable of expression by light, for example, simply lights and flashes during a notification period by selecting one color or a fixed combination from the plurality of LEDs and there is a limit to identification of originators, and also it was impossible for a user to freely create incoming notification patterns and an ability to express originality was also poor.
SUMMARY OF THE INVENTION
This invention is implemented in view of the above-mentioned circumstances, and it is an object of the invention to provide an incoming notification pattern setting circuit and method of a portable telephone constructed so that driving patterns can also be set freely to incoming notification means by a vibrator while combinations of lighting colors or lighting patterns can be set freely from the outside to incoming notification means by light.
In order to solve the above problems, an incoming notification pattern setting circuit of a portable telephone of the present invention comprises memory means for storing data of notification patterns and data of the tempo for generating patterns of a change in lighting colors by combinations of flashing of plural LEDs by respectively driving the plural LEDs with different colors every tempo, driving data generation means for repeatedly generating driving data for driving the plural LEDs by data written from said memory means, and driving means for independently driving the plural LEDs respectively
