The master terminal 10 corresponds to, for example, a mobile phone, a PHS, or the like, and is charged for the multi-party service. The master terminal 10 can perform the same operation as that of the master terminal 100 of the prior art, but has the greatest feature in that the following operation is performed.
[0030]
In particular, the master terminal 10 can receive other slave terminals participating in the multi-party service or the telephone number of the master terminal 10 from the slave terminals 21, 22, 23. When a transmission request for information including any of the call time, billing information, and location information (hereinafter referred to as “multi-party service information”) is received, the multi-party service information is provided to the switching center 30.
[0031]
When the master terminal 10 receives an incoming call from a slave terminal that does not participate in the multi-party service while the multi-party service is being performed, the master terminal 10 sends multi-party service information to the slave terminal. Provided through the switching center 30.
[0032]
The slave terminals 21, 22, 23,... Correspond to, for example, mobile phones, PHS, etc., and are not subject to billing during multi-party services. The slave terminals 21, 22, 23... Can be operated in the same manner as the conventional slave terminals 201, 202, but the greatest feature is that they perform the following operations.
[0033]
Since the slave terminals 21, 22, 23,... Have a key input unit having a function for requesting multi-party service information, the user of the slave terminal can perform multi-time communication while participating in the multi-party. Request party service information. When the slave terminal acquires multi-party service information, the slave terminal displays the multi-party service information on a display unit included in the slave terminal.
[0034]
When the slave terminals 21, 22, 23,... Do not participate in the multi-party service and make a call to the master terminal 10 in the multi-party service and change state during the call waiting, the exchange 30 The multi-party service information at that time is acquired, and the acquired multi-party service information is displayed on its own display unit.
[0035]
Further, when the multi-party service is being performed, when the master terminal 10 places any slave terminal in the multi-party on hold and makes a call with a slave terminal outside the multi-party, the master terminal 10 is put on hold. The slave terminal obtains multi-party service information including the telephone number of the slave terminal that communicates with the master terminal 10 from the switching center 30, and displays the obtained multi-party service information on its display unit.
[0036]
Furthermore, when the master terminal 10 puts any slave terminal in the multi-party on hold, the slave terminal not put on hold in the multi-party receives multi-party service information including the telephone number of the slave terminal put on hold. The multi-party service information acquired from the exchange 30 is displayed on its own display unit.
[0037]
Further, when the master terminal 10 terminates (disconnects) any slave terminal in the multi party while the multi party service is being performed, the slave terminal that is not terminated in the multi party is: Multi-party service information including the telephone number of the slave terminal to be terminated is acquired from the switching center 30, and the acquired multi-party service information is displayed on its own display unit.

As shown in FIG. 9B, the display units of the slave terminals 21 and 22 display the telephone numbers of the master terminal 10 and the slave terminal 23 in addition to the slave terminal 21 or the slave terminal 22 being on hold. Therefore, the user of the slave terminals 21 and 22 put on hold can grasp who the user of the master terminal 10 is currently talking with.
[0063]
FIG. 5 shows still another operation sequence of the multi-party service system 1. The operation sequence shown in FIG. 5 may be a continuation of the operation sequence shown in FIG. In FIG. 5, it is assumed that a call is made in advance between the master terminal 10 and the slave terminal 23, and the slave terminal 21 and the slave terminal 22 are on hold. In this state, the user of the master terminal 10 performs a call operation for causing the slave terminal 21 and the slave terminal 22 on hold to participate in the multi party.
[0064]
Thereby, a multi-party call request for joining the slave terminal 21 and the slave terminal 22 to the multi-party is transmitted from the master terminal 10 to the switching center 30 (step S40). Upon receiving the multi-party call request, the switching center 30 first transmits multi-party service information including the telephone numbers of the slave terminals 21 and 22 to the slave terminal 23 that is currently making a call (step S41). When the slave terminal 23 receives the multi-party service information, the slave terminal 23 displays the multi-party service information on its display unit.
[0065]
Next, the switching center 30 transmits a hold release request for releasing the hold and multi-party service information including the telephone numbers of the slave terminals 22 and 23 to the slave terminal 21 (step S42). Then, a hold release request and multi-party service information including the telephone numbers of the slave terminals 21 and 23 are transmitted to the slave terminal 22 (step S43). The slave terminal 21 and the slave terminal 22 that have received the multi-party service information display the received multi-party service information on their display units.
[0066]
On the other hand, when the exchange 30 finishes transmitting the hold release request and the multi-party service information to the slave terminal 21 and the slave terminal 22, it sends a hold release confirmation to the master terminal 10 as a response to the master terminal 10. Along with (Step S44), a multi-party call confirmation indicating that the multi-party call has been established is transmitted (Step S45). Thus, the four parties of the master terminal 10, the slave terminal 21, the slave terminal 22, and the slave terminal 23 form a multi-party, and perform simultaneous calls with each other.
[0067]
FIG. 6 shows still another operation sequence of the multi-party service system 1. The operation sequence shown in FIG. 6 may be a continuation of the operation sequence shown in FIG. It is assumed that a multi-party is configured in advance among the four parties of the master terminal 10, the slave terminal 21, the slave terminal 22, and the slave terminal 23, and a simultaneous call is performed mutually. In this state, the user of the master terminal 10 performs an operation for putting the slave terminal 21 on hold.
[0068]
As a result, a multi-party hold request indicating that the slave terminal 21 is put on hold is transmitted from the master terminal 10 to the switching center 30 (step S51). The exchange 30 that has received the multi-party hold request transmits the multi-party hold request to the slave terminal 21 and sets the slave terminal 21 to hold (step S52). At this time, the display unit of the slave terminal 21 displays that the slave terminal 21 has been put on hold.
[0069]
After completing the transmission of the multi-party hold request, the exchange 30 transmits a multi-party hold confirmation as a response to the master terminal 10 to the master terminal 10 (step S53).
[0070]
Next, the switching center 30 transmits multi-party service information for notifying that the slave terminal 21 has been put on hold to the slave terminals 22 and 23 (steps S54 and S55). Thereby, the users of the slave terminal 22 and the slave terminal 23 can know that the slave terminal 21 has been put on hold.
[0071]
