DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an incoming call receiving system, and more particularly to a mobile communication system (PMT: Persona).
l Mobile Telecommunication
In n), the present invention relates to a call termination method for a PMT mobile subscriber having a call waiting service.

[0002]

2. Description of the Related Art When an incoming call is received by a PMT mobile subscriber who has a call waiting service during a call using a PMT mobile device that is not registered for incoming call, the incoming call is registered in the conventional PMT connection system. The incoming connection is made only to the PMT mobile station.

[0003]

In this conventional PMT connection system, when a PMT mobile subscriber who has a call waiting service during a call using a PMT mobile station for which a call is not registered receives a call, a call is made. A second PMT mobile station different from the PMT mobile station that is currently engaged in calling the second call that is received by the call waiting service in order to make an incoming connection to the PMT mobile station that has registered the incoming call instead of the current PMT mobile station. In order to answer the second call, the PMT mobile station receiving the second call needs to be close to the active PMT mobile subscriber and be aware of the second call. Conditions that can be met, and separate P

SUMMARY OF THE INVENTION An object of the present invention is to improve the above-mentioned problems, and to provide a PMT having a call waiting service during a call using a PMT mobile station that has not been registered for incoming calls.
It is an object of the present invention to provide a call receiving method in which a mobile subscriber can receive a call to a currently-talking PMT mobile device regardless of call registration when a call is received.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described with reference to the drawings. FIG. 1 is a connection diagram of the present invention.
The PMT device of the mobile subscriber 1, the PMT mobile device 2 currently used by the PMT mobile subscriber 1 that has not been registered, and the PM 3 that has been registered by the PMT mobile subscriber 1.
The T mobile unit 4 is a call which is being talked by the PMT mobile subscriber and is a second call which has been received because the PMT mobile subscriber 1 has a call service. The second call 5 is connected to the PMT mobile station used by the PMT mobile subscriber 1 for the call regardless of the incoming call registration.

FIG. 2 is a diagram showing an incoming call registration procedure, 6 is an incoming call registration signal for performing incoming call registration, and 7 is a database for storing PMT mobile subscriber information / PMT mobile device information. The database 7 stores a registered MSI as information for identifying a PMT mobile station that has received and registered for information (MSN) for identifying a PMT mobile subscriber.

FIG. 3 is a diagram showing an incoming call procedure when the PTM mobile subscriber is not talking on the telephone. Reference numeral 8 denotes an exchange which performs call control, and reference numeral 9 denotes an incoming information reading signal for reading out incoming information from the database 7. Reference numeral 10 denotes a mobile subscriber call signal for calling a PMT mobile subscriber. If the busy MSI is not set when the incoming call information is read out, the registered MSI is changed to the busy MSI when the incoming call is registered, and the registered MSI is changed in response to the incoming call information reading signal 9. Will be returned. When the exchange 8 calls the PMT mobile subscriber with the PMT mobile station call signal 10, the exchange M
PMT mobile station 3 that has registered the incoming call to use SI
Incoming call.

FIG. 4 shows a transmission procedure. Reference numeral 11 denotes a transmission notification signal for notifying the switching center 8 of the transmission, and reference numeral 12 denotes a transmission information read signal for reading transmission information. The exchange 8 registers the incoming call registered in the call notification signal 11
The MT mobile station (MSI ') is reported to the database 7 by the transmission information read signal 12, and the database 7 changes the registration of the MSI' reported by the transmission information read signal 12 to the MSI during the call.

FIG. 5 is an image diagram showing an incoming call procedure when a PMT mobile subscriber is talking on the telephone. Reference numeral 8 denotes an exchange for performing call control, and reference numeral 9 denotes an incoming information reading signal for reading out incoming information from a database. Reference numeral 10 denotes a mobile subscriber call signal for calling a PMT mobile subscriber. If the busy MSI is set when the incoming call information is read out, the database 7 returns the busy MSI in addition to the registered MSI in response to the incoming call signal 9. When the exchange 8 calls the PMT mobile subscriber by the mobile subscriber paging signal 10, the PM 8
If the T mobile subscriber is engaged in a call and implements the call waiting service, a call arrives at the PMT mobile device currently used for the call in order to use the MSI during the call.

FIG. 6 is an image diagram showing a call termination procedure.
13 is a disconnection signal for notifying the exchange 8 of the disconnection, 14
Is a disconnection notification signal for notifying the database 7. The database 7 deletes the MSI during the call when the disconnection is reported by the disconnection notification signal 14.

Thus, the embodiment of the present invention shown in FIG.
After the incoming call registration procedure shown in FIG. 2 is performed, the incoming call procedure shown in FIG. 5 is activated during a call by the outgoing call procedure shown in FIG. 4, and a call is received by the call waiting service to the PMT mobile device during the call. This can be realized by deleting the MSI during a call by the call termination procedure shown in FIG.

[0013]

As described above, according to the present invention, when a second call is received by a PMT mobile subscriber who has a call waiting service during a call using a PMT mobile device that has not registered the incoming call, Irrespective of the incoming call registration, there is an effect that the call waiting service can be easily implemented by receiving the second call to the currently active PMT mobile station.
