ABSTRACT:

BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a multimedia terminal device for communicating by radio with a base station by multimedia.
2. Description of the Related Art
Recently a multimedia radio communication system in which a plurality of information media are combined has been wide spread.
As a terminal for connecting to the multimedia radio communication system, a voice terminal, a facsimile terminal, an ISDN terminal, a data terminal and so on are known. Further a voice composite terminal for switching a line in using is also known.
Examples of a conventional multimedia radio communication system are disclosed in Japanese unexamined patent publication No. 5-183654 and Japanese unexamined patent publication No. 6-44157.
FIG. 1
illustrates a schematic diagram of a conventional multimedia radio communication system.
As illustrated in
FIG. 1
, a conventional multimedia radio communication system is composed of various terminals (described as “mobile station side terminal” in the following)
101
, mobile station apparatus
102
connected to each mobile station side terminal
101
separately and base station apparatus
103
for communicating by radio with mobile station apparatus
102
.
Base station apparatus
103
is connected to network
104
using cables, and network
104
is connected to various terminals (described as “network terminal” in the following)
105
.
In the case where a mobile station side terminal
101
of facsimile terminal initiates a data communication request to network terminal
105
, mobile station side terminal
101
first provides a connection request to base station apparatus
103
via mobile station apparatus
102
.
And in the case where it is confirmed that network terminal
105
is available by base station apparatus
103
via network
104
, base station apparatus
103
provides the service receipt information to mobile station side terminal
101
via mobile station apparatus
102
.
Then a radio data communication is performed by a facsimile signal between mobile station side terminal
101
and network terminal
105
.
Next, in the case where, while a radio data communication is performed by facsimile between network terminal
105
and mobile station side terminal
101
, mobile station side terminal
111
differing from a facsimile terminal, for instance a voice terminal, initiates a data communication request to network terminal
115
, mobile station side terminal
111
provides a connection request to base station apparatus
103
via mobile station apparatus
112
.
In the case where it is confirmed that network terminal
115
is available by base station apparatus
103
, base station apparatus
103
provides the service receipt information to mobile station side terminal
111
via mobile station apparatus
112
.
Then a radio data communication is performed by voice signal between mobile station side terminal
111
and network terminal
115
.
However in the conventional multimedia radio communication system described above, since each terminal is connected to a mobile station apparatus separately, in the case where data communications by different media are performed, it has the problem that a mobile station apparatus is necessary for each sort of data communications.
SUMMARY OF THE INVENTION
The present invention has an object to provide a multimedia radio communication system in which communications from more than two terminals can be performed with one mobile station apparatus for communicating by radio with a base station apparatus.
The object is achieved by connecting more than two terminals to one terminal interface adapter connected to a mobile station apparatus.
