Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a call waiting method that connects a calling subscriber who has made a call to a mobile subscriber during a call with the mobile subscriber after the mobile subscriber ends the call. be.

When a mobile subscriber who is on a call receives a call, in conventional mobile communication connection systems, only a busy tone or the like is used to notify the originating subscriber that the mobile subscriber is busy. Therefore, the originating subscriber was required to dial again after on-hooking once. In addition, this re-call involves setting up a new radio, calling the called subscriber after the radio line has been set up, and responding to the called subscriber. There was a drawback that it hindered the effective use of.

The present invention has improved the above-mentioned drawbacks, and its purpose is to notify a mobile subscriber of an incoming call while the call is in progress, and to terminate the call using the wireless line in use. The purpose of the present invention is to connect the calling subscriber later during a call, thereby making effective use of the radio line, and improving the operability of the calling subscriber. Examples will be described in detail below.

FIG. 1 is a block diagram of an embodiment of the present invention, in which 1 is a mobile subscriber, 2 is a general telephone that is communicating with the mobile subscriber 1, 3 is a switching network,
4 is a wireless base station; 5 is a general telephone; 6 is a connection control device; 7 is a call guidance talkie device that notifies the called subscriber during a call that a call has arrived; This is a standby talkie device that notifies the user that the user is currently on a call and should remain on standby.

General telephone 2 and switching network 3,
Mobile subscriber 1 making a call via wireless base station 4
When a call is received from the regular telephone set 5, the connection control device 6 analyzes the dialed digits from the regular telephone set 5 and finds out that the mobile subscriber 1 corresponding to the dialed number is busy. , controls the switching network 3, connects the incoming call guidance talkie device 7 to the communication path in the switching network 3 used by the general telephone 2 and the mobile subscriber 1 for communication, and At the same time, the general telephone 5 and the standby guidance talker 8 are connected to notify the mobile subscriber 1 that the mobile subscriber 1 has received a call.
is currently on a call, so it notifies you to stay on standby. When the mobile subscriber 1 receives this incoming call notification, the mobile subscriber 1 maintains the off-hook state even if the conversation with the general telephone 2 ends, and if the general telephone 5 also receives the standby notification, the mobile subscriber 1 maintains the off-hook state. Try to maintain this condition.

When the connection control device 6 identifies that the call between the mobile subscriber 1 and the general telephone 2 has ended due to the on-hooking of the general telephone 2, the connection control device 6 controls the switching network 3 and connects the mobile subscriber. The wireless line used for the call between the person 1 and the regular telephone 2 is put on hold, and then the regular telephone 5 connected to the standby guidance talkie device 8 is connected to the previously put on hold wireless line. , connects the mobile subscriber 1 and the general telephone set 5.

In the embodiment, the incoming call guidance and standby guidance are announced by voice using the incoming call guidance talker device 7 and the standby guidance talker device 8.
Similar to the busy call display used in general telephone networks, notification can also be made with a signal tone.

As explained above, when a mobile subscriber who is on a call receives an incoming call, the wireless line used for the current call is put on hold even after the call ends, and the incoming call is connected to the mobile subscriber who is on the call. Since the system is designed to be used for telephone calls as well, the wireless line only needs to be set up once for multiple calls, which has the advantage of improving the efficiency of wireless line usage. Furthermore, since the mobile subscriber who is talking is notified of the arrival of a call, the effect of shortening the length of the call can be expected, and the efficiency of using the radio line can be further improved. In addition, if the calling subscriber who made a call to a mobile subscriber who is currently on a call remains on standby, the call will be automatically connected to the mobile subscriber after the call ends, so there is no need to redial. This has the advantage of improving the usability of the originating subscriber.
