Communication system and communication control apparatus
First Claim
1. A communication system comprising:
- a communication control apparatus connected to a plurality of types of communication lines with different communication methods; and
a plurality of communication terminal apparatuses that are connected to the communication control apparatus and perform communications with external communication terminal apparatuses via the plurality of types of communication lines, wherein the communication control apparatus includes;
identification information storage means for storing identification information for identifying a communication terminal apparatus of another party that is communicating with the communication terminal apparatus;
control means for performing control such that when the communication terminal apparatus is about to start particular communications using a communication line of a particular type and another communication terminal apparatus is already performing communications using the communication line of the particular type, then the communications that are currently being performed are disconnected and the particular communications are started; and
reconnection means for, when the communications are disconnected by the control means, reconnecting the disconnected communications using another communication line that is not being used for communication, based on the identification information stored in the storage means.

Abstract
When a telephone apparatus makes a particular and emergency call using a telephone communication line and another telephone apparatus is already performing communications using the telephone communication line, then the control apparatus controls refers to a particular/emergency number table stored in a storage device and disconnects the communications that are currently being performed to transmit signals for the particular and emergency call. The control apparatus disconnects the communications and also reconnects the disconnected communications using an Internet communication line by referring to a line use status table stored in the storage device. At the time of the disconnection, an announcement that the communications are to be disconnected is also made beforehand to the telephone apparatus the communications over which are to be disconnected.

19. A communication system comprising:
-
a communication control apparatus connected to a communication line that can perform communications simultaneously using a plurality of types of communication methods; and
a plurality of communication terminal apparatuses that are connected to the communication control apparatus and perform communications with external communication terminal apparatuses via the communication line, wherein the communication control apparatus includes;
identification information storage means for storing identification information for identifying a communication terminal apparatus of the other party that is communicating with the communication terminal apparatus;
control means for performing control such that when the communication terminal apparatus is about to start particular communications using a particular communication method and another communication terminal apparatus is already performing communications using the particular communication method, then the communications that are currently being performed are disconnected and the particular communications are started; and
reconnection means for, when the communications are disconnected by the control means, reconnecting the disconnected communications using a communication method other than the particular communication method, based on the identification information stored in the storage means.

20. A communication system comprising:
-
a gateway apparatus connected to an analog communication line and a digital communication line; and
a plurality of telephone apparatuses that are connected to the gateway apparatus and perform communications with external telephone apparatuses via the analog and digital communication lines, wherein the gateway apparatus includes;
identification information storage means for storing identification information for identifying a telephone apparatus of the other party that is communicating with the telephone apparatus;
communication control means for controlling such that when the telephone apparatus is about to start particular communications using the analog communication line and another telephone apparatus is already performing communications using the analog communication line, then the communications that are currently being performed are disconnected and the particular communications are started; and
reconnection means for, when the communications are disconnected by the communication control means, reconnecting the disconnected communications using the digital communication line, based on the identification information stored in the storage means. - View Dependent Claims (21)
