Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mobile phone to which a communication service in mobile communication is applied.

[0002]

2. Description of the Related Art In recent years, with the rapid progress of mobile communication networks, various services have been provided to mobile phone users. For example, there is a call waiting service that can respond to a new incoming call while holding a call state when a new interrupted incoming call is received during a call, and a three-party call service that allows a user to talk with an interrupting party.

An embodiment of a conventional call waiting service and a three-way call service will be described with reference to a portable telephone system 10 shown in FIG. The mobile phone system 10 shown in FIG. 12 includes a mobile phone 1 owned by a user B, a mobile phone 3 owned by a user A, and a mobile phone 4 owned by a user C.
Are connected via the communication network 2.

The mobile phone 1 owned by the user B is a PDC (Pe
It is assumed that the user B has subscribed to a call waiting service and a three-way call service based on the PDC system in a digital mobile phone compatible with an rsonal digital cellular (rsonal digital cellular) system.

[0005] The PDC system is one of transmission systems for digital mobile phones, and uses TDMA (Ti
me Division Multiple Access (time division multiple access) method is adopted. The TDMA scheme is a scheme in which channels are separated according to time, and one frequency is alternately shared by a plurality of users in a short time.

In FIG. 12, it is assumed that the user A and the user C use the mobile phones 3 and 4, respectively, but they may be a mobile phone or a fixed phone.

The flow of communication connection between the mobile phones 1, 3, and 4 when the conventional call waiting service and the three-way call service are applied to the mobile phone 1 owned by the user B will be described.
This will be described with reference to FIG.

[0008] As shown in FIG.
If the user C interrupts the user B while talking to the user A using one channel (solid line in the figure), the user B is notified of the interruption by the user C by a notification sound. . At this time, the user B
When a call is answered from the user C by hooking or key operation, the user A is put on hold (two-dot chain line in the figure) and the user B uses a different channel from the above. By doing so, the communication line with the user C is established, and the communication with the user C is started.

Further, as shown in FIG. 13B, when the user B ignores the notification sound or disconnects the connection with the user C by operating a key, the communication with the user A is continued.

[0010] As shown in FIG.
While talking to user A using two channels, user C
Is interrupted by the user B, the user B prompts the user A to talk with the user C, and performs a key operation, so that the user B further uses another channel to communicate with the user C. Establishing the communication line of the third party makes a transition to a three-party call with the user A and the user C.

Further, as shown in FIG. 13D, when the user B ignores the interrupt notification sound of the user C or disconnects the connection with the user C by operating a key, the communication with the user A is continued. You.

Further, although not shown, user B calls user C while talking with user A, and user A
There is also a case where a transition to a three-party call between the user and the user C is made.

[0013]

However, FIG.
In the conventional call waiting service shown in
In the case of the A-type PDC system, since a plurality of channels are multiplexed to form one carrier, only the user B responds to an interrupt from the user C, and all the set channels are blocked. However, there is a problem that the user B can only distinguish between the user A and the user C, and has few options.

Also, in the conventional three-way call service, for the same reason as described above, in response to the interruption from the user C, the user B continues the call with the user A,
This is an alternative to switching to a three-party call between the user A and the user C, which also has a problem that there are few options and that it is not possible to flexibly cope with a plurality of interrupts.

[0015] Furthermore, mobile phones that are currently in widespread use are:
Although it has not only a call function but also a data communication function, data communication has a larger data volume than a voice call, and a single channel is not enough. When communication is performed, the conventional communication services for mobile phones are not sufficient for users, such as the inability to use multiple terminal functions at the same time, such as the inability to make voice calls, and the reduced number of available users. Did not.

Therefore, CDMA (Code Division) is used as a mobile phone access method capable of multi-channeling.
A system using a spread spectrum technique called Multiple Access (code division multiple access) has been proposed. CD
The MA method is a method of separating channels by assigning different spreading codes to each user.
A large number of user channels per frequency bandwidth can be set.

Further, W-CDMA is used as a CDMA system which is broadened so as to support multimedia.
(Wideband CDMA: Wideband Code Division Multiple Access) has been proposed. When the W-CDMA system is adopted, a multi-channel service that enables simultaneous use of voice communication and data communication or a multi-call service that allows three or more people to communicate as shown in FIG. You. In FIG. 14, a W-CDMA mobile phone system 20 enables a mobile phone 1 owned by a user B as a service subscriber to be interconnected with a plurality of mobile phones via a communication network 2. .

However, at present, there are few specific proposals for communication services that make full use of the W-CDMA system.
