Mobile Phone Patent Description
1. Field of the Invention
The present invention relates to a system combining a pager type
personal digital assistant and a mobile phone module, wherein a
pager type personal digital assistant and a mobile phone module
are integrated as an integral device. Users operate the system at
any time and place; data and speech can be transferred bidirectionally
through three channels; and data propagation can be realized in
time.
2. Background of the Invention
Currently, stocks and futures are important tools in financial
management. However, not everyone has time to a stock or future
office for transaction. Therefore, many electronic products are
developed, thereby, the subscribers monitor the prices of the stocks
and futures through the screens of these electronic products.
Referring to FIG. 1, a conventional pager display flow diagram
for displaying texts and numbers are illustrated. A pager 13 showing
the prices of stocks is developed. In a data servo 11, the broadcasting
data is transferred all day long to a paging system transmitting
state 12. Then the data is sent to the subscribers through a wireless
paging system. Therefore, the subscribers may know the prices of
stocks through the display. Since the screen of the pager is too
small so that only a few texts are displayed. Therefore, the efficiency
is low.
Referring to FIG. 2, another conventional personal digital assistant
connected with a mobile phone for transmitting data bidirectionally
is illustrated. The personal digital assistant with a larger liquid
crystal display is connected to a wireless pager system. Thereby,
the subscriber may acquire data about stocks. Then a transmission
line is used to connect the mobile phone for performing stock transaction.
The structure includes a data servo 21. Data can be transferred
to the mobile phone of the subscribers through a transmitting station
22 or a GSM/DCS base station 24 and then the mobile phone is further
connected to a pager type personal digital assistant 23. However,
this device is not convenient. If the mobile phone is updated, then
the whole transmission device must be updated. Furthermore, if user
forgets to carry a mobile phone or the battery of the mobile is
exhausted, then the user can not transact. Furthermore, the total
space of the mobile phone and the personal digital assistant is
larger and thus it is inconvenient.

speech can be transferred bidirectionally. The data propagation
can be realized in time.
Referring to FIG. 3, a schematic view shows the structural block
view of the present invention. The system provider emits a whole
day real-time broadcast information through a pager system. The
information is received by a built-in pager 31 of the present invention.
Then a speaker or trumpet 32 emits a voice promise to inform the
user a message being received, it is continuously transferred to
a central processing unit 33 for being processing. The central processing
unit 33 may operate and process each unit of a personal digital
assistant unit 34. This personal digital assistant unit 34 is formed
by the following components: an infrared port 341, a key platform
342, a liquid crystal display 343, a memory 344, and a security
device 345, and other units. The mechanism of each component will
be described in the following:
(1) An infrared port 341: The infrared port 341 may perform data
transformation with other electronic device with another infrared
port in a certain distance, thereby, transmission line being unnecessary.
(2) A key platform 342: The key platform 342 includes a plurality
of directional keys for controlling the cursor in the frame to move
upwards, downwards, leftwards, and rightwards. An input key is used
to perform the function of choice, or an electrostatic sensing pen
is used to control a cursor and perform a clicking operation.
(3) A liquid crystal display 343: The liquid crystal display 343
is installed in a proper position on a surface of the personal digital
assistant 34 for displaying all information to the user.
(4) A memory 344: The memory 344 stores all data, thereby, user
may read all received data.
(5) A security device 345: The security device 345 is a protecting
circuit for preventing from an improper operation to damage a personal
digital assistant 34.
The pager 31 is combined with the personal digital assistant unit
34 so as to be formed as a proper pager type personal digital assistant.
However, the novelty of the present invention is that a mobile phone
structure is added to the combined structure. At first, a power
switch 35 is installed at a selected position in the personal digital
assistant unit 34 for switching a mobile phone system. A GSM/DCS
integrated circuit 36 is built--in the present invention for controlling
the structural system 37 for processing a mobile phone. The mobile
phone system controlled comprises the following components:
1. A memory 371: The memory 371 is dedicated to the mobile phone
system for storing telephone numbers, text short messages, and other
data for a short time period.

372 is installed within the mobile phone system and is a metal chip
set recording with the number of the mobile phone, the system provider
of the mobile phone; programs for actuating the mobile phone, and
other related data, and memory space.
3. A speaker/microphone 373: The speaker is installed in the receiver
of a mobile phone for propagating the system provider from the mobile
phone base station. Furthermore, the microphone is installed at
the voice emitting end of the mobile phone. The received audio signal
is analog/digital--converted so that the system provider is emitted
to the mobile phone base station from the mobile phone.
4. A hand free receiver 374: The hand free receiver 374 is inserted
to an audio connecting port of the personal digital assistant unit
34 and has an outlook like an earphone. A microphone is installed
below the receiver (speaker). When the user is busy, or is desired
to prevent electromagnetic interference, This device is effectively

Above components are connected to a GSM/DCS integrated circuit
36 for controlling and processing speech signal. The speech signal
is sent to a communication interface 38 at the same time. The structure
includes the following components: an analog/digital converting
circuit, a digital/analog converting circuit, a GSM/DCS channel
selecting circuit, an antenna etc. The communication interface has
the functions of transmitting and receiving speech signals. The
mobile phone system of the present invention is a GSM/DCS dual--frequency
system, which has two frequency channels for bidirectionally transmitting
speech and data signals. In that, data is sent by a wireless application
protocol (WAP) as a standard of bidirectional data transmission.
Referring to FIG. 4, an operational flow diagram of the present
invention is illustrated. The process of pager receiving mode and
personal digital assistant mode comprises the steps of starting
(step 41); turning on the power (step 411); actuating the personal
digital assistant (step 412); pager in the personal digital assistant
receiving a message from a broadcast system (step 413); determining
whether the system is operated in normal (step 414); if not, returning
the process back to (step 412); if yes, actuating the GSM/DCS power
(step 42); performing a speech selecting process (step 421); performing
an idle mode process (step 422); performing a connection process
(step 423); performing a connection and conversion process (step
424) and a continuous releasing process (425); determining whether
the work is performed in normal (step 426); if no, the process returning
to (step 421) and processes 421 to 425 are repeated; if yes, the
GSM/DCS is complete (step 43); actuating in normal condition (step
44); and then end ending the process in (step 45).
The present invention utilizes three channels. As the present invention
is used in the transmission of data and speech, the receiving and
transmitting of the channels can be performed perfectly. The frequency
channels of the present invention is:
1. Paging system: A frequency band of 285.about.1375 MHz is used
in unidirectional for propagating unidirectionally, then, the signal
is received by the built-in pager of the present invention in time.
2. GSM system: A transmitting frequency band GSM system is 880.about.915
MHz and a receiving frequency thereof is 925.about.960 MHz for bidirectionally
broadcasting and receiving data and speech signals.
3. DCS system: A transmitting frequency band DCS system is 1710.about.1785
MHz and a receiving frequency thereof is 1805.about.1880 MHz for
bidirectionally broadcasting and receiving data and speech signals.
The present invention are thus described, it will be obvious that
the same may be varied in many ways. Such variations are not to
