ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention relates to a radio-signal transceiver receiving a message transmitted from a base station and a method of controlling a radio-signal transceiver, and more particularly to a radio-signal transceiver which is capable of reducing a work volume of inputting data thereinto by an operator to thereby enhance serviceability thereof, and a method of controlling a radio-signal transceiver, capable of doing the same.
2. Description of the Related Art
There have been suggested various radio-signal transceivers. One of such radio-signal transceivers is disclosed in Japanese Unexamined Patent Publication No. 8-307919, as a radio-signal selective calling receiver. The disclosed radio-signal selective calling receiver is illustrated in FIG.
1
. For instance, the illustrated radio-signal selective calling receiver
40
may be used as a pager or a pocket bell.
With reference to
FIG. 1
, the radio-signal selective calling receiver
40
is comprised of an antenna
41
, a receiver
42
receiving a message through the antenna
41
, a decoder
43
decoding a received message, a controller
44
controlling an operation of the radio-signal selective calling receiver
40
, a memory
45
storing tables therein, a display screen
46
displaying a received message, an amplifier
47
, a speaker
48
informing a user that a message has been received, and a switch
49
.
The controller
44
includes a random access memory (RAM)
441
therein. The memory
45
includes a first table
451
, a second table
452
and a third area
453
.
The first table
451
contains a plurality of routine sentences having been made in advance. When the controller
44
judges to receive a specific code from a transmitter, the controller
44
reads a routine sentence associated with the received specific code, out of the first table
451
, and displays the thus read-out sentence on the display screen
46
. Such routine sentences to be stored in the first table
451
may be made by a manufacturer of a radio-signal selective calling receiver or a user.
The second table
452
is used for converting a received message into other language. For instance, if a received message contains Chinese characters, the received message is converted into the Japanese syllabary (kana), for instance. The third area
453
is an area for storing the thus converted message therein.
The radio-signal selective calling receiver
40
illustrated in
FIG. 1
is designed to include two tables
451
and
452
. When the radio-signal selective calling receiver
40
receives a message, the controller
44
reads out a control code assigned to a message at a head thereof. If the read-out control code indicates a routine sentence, the controller
44
converts the received message into a routine sentence through the first table
451
, and displays the routine sentence on the display screen
46
. If the read-out control code indicates a sentence other than a routine sentence, the controller
44
converts the received message into the Japanese syllabary, for instance, through the second table
452
, and displays the thus converted sentence on the display screen
46
.
In the conventional radio-signal selective calling receiver
40
, characters and figures are input and registered through quite complicated operation, and specific data may be input thereinto. A message is transmitted from a transmitter to the radio-signal selective calling receiver
40
through a radio-signal, and data can be registered only from a single transmitter in one registration operation.
Hereinbelow is explained an operation of the radio-signal selective calling receiver
40
.
A message addressed to a calling number of the radio-signal selective calling receiver
40
is received at the receiver
42
through the antenna
41
. The thus received message is decoded by the decoder
43
, and then, is transmitted to the controller
44
. The controller
44
converts the received message into the Japanese syllabary, for instance, letter by letter through the second table
452
stored in the memory
45
. When the controller
44
reads out a routine sentence registration code and a registration number appearing after a conversion completion code, the controller
44
stores the message having been converted into the Japanese syllabary, in association with the registration number, in the third area
453
in the memory
45
.
As mentioned so far, a certain message is registered as a routine sentence in the conventional radio-signal selective calling receiver
40
.
The radio-signal selective calling receiver
40
is designed to have the limited number of operation buttons because of downsizing of the receiver. As a result, characters and figures are input and registered in the radio-signal selective calling receiver
40
through quite complicated and laborious steps. The radio-signal selective calling receiver
40
is accompanied with a problem that it can register a received message relating to specific registration data, but cannot register received messages relating a plurality of registration data.
Some transceivers are designed to have an external interface function for making wiring communication and optical communication. However, if communication interface format were not unified, it would be impossible to register data in such transceivers, resulting in a problem that a user cannot readily register data.
In addition, if a plurality of users commonly use one data, each of users has to register data in each of their receivers. That is, in accordance with the conventional radio-signal selective calling receiver
40
, it was not possible to register data in a plurality of the receivers in a single registration step.
Various radio-signal transceivers have been suggested as follows.
Japanese Unexamined Patent Publication No. 8-186635 has suggested a radio-signal selective calling receiver. In the suggested radio-signal selective calling receiver, received data is processed into telephone directory data, and stored in a memory. Data stored in a memory and individual message data are sorted. In addition, selected one among telephone directory data and individual message data is read out, and is erased. A certain individual calling address number is read out among telephone directory data stored in a memory, and is transmitted through a dialer. The radio signal selective calling receiver also includes a dialer connector terminal and a printer connector terminal such that individual message data can be printed through a printer connected thereto.
Japanese Unexamined Patent Publication No. 9-64761 has suggested a radio-signal receiver comprised of an antenna, a receiver receiving a radio-signal through the antenna, a data table obtaining a line of characters, based on data having been received at the receiver, associating a certain sentence made by a transmitter with an identifier for identifying the sentence to thereby make a routine sentence, and storing the sentence therein, a display screen displaying the line of characters having been obtained in the data table, an interface, and a controller controlling radio-signal receiving operation of the receiver, writing/reading operation of the data table, and display operation of the display screen, in accordance with a signal input through the interface.
Japanese Unexamined Patent Publication No. 9-65395 has suggested a method of storing a number in a memory of a pager, including the steps of calling the pager through a telephone, inputting a telephone number and associated data to be registered, into the telephone in the form of a message, and storing the telephone number and associated data, which have been received at the pager, in the memory.
Japanese Unexamined Patent Publication No. 9-247725 has suggested a mobile radio-signal transceiver transmitting a message stored in a memory in association with a predetermined number, in accordance with a selective-calling signal transmitted from a base station. The mobile radio-signal transceiver is comprised of means for judging whether the selective
