Description

Mobile device capable of three-way calling and method thereof

The present invention relates to a mobile device and method thereof, and more particularly to a mobile device capable of three-way calling and a method thereof.

With the increasing popularity of mobile communication devices, the standards of mobile communication are increasingly complex and sophisticated to meet users' needs for clearer call quality, video calls, instant messaging, and large bandwidth data transmission. At present mobile communication standard commonly used, namely Universal Mobile Telecommunications System (Global System for Communications, GSM) , CDMA (Code Division Multiple Access, CDMA) , the third generation of mobile communications technology (3 ^rd Generation, 3G) and Personal Handy-phone System (PHS) and so on. Many single mobile phones on the market can support two or more communication standards, so that mobile phones can communicate according to local conditions.

In addition, mobile phones in many regions have developed so-called "dual card dual standby" applications, which can use two different door numbers at the same time. For example, two different mobile communication system providers can simultaneously serve to increase the mobile phone's Mobility, breaking through the limits of space, and achieving the purpose of not missing important calls when and where. The "Double Card Dual Standby" mobile phone can also meet the purpose of mobile phone users using different door numbers to distinguish contact groups. The "Double Card Dual Standby" mobile phone can simultaneously insert two SIM (Subscriber Identity Module) cards and standby with two different door numbers. However, when one of the door numbers is in a call state, the other door number cannot be connected at the same time, but can only be in Standby state. Later, the mobile phone with the so-called "dual card dual standby dual-pass" function can be connected at the same time with two door numbers, but only one of the door numbers is in a call state, and cannot be performed in a three-way call.

At present, the mobile phones that claim to be able to make three-way calls are all provided by mobile communication system providers, not the services generated by the mobile phone itself using two different door numbers. However, the three-party calling service provided by the mobile communication system provider usually requires an additional fee. Therefore, if a method for making a three-party call using a dual-card mobile phone can be provided, it will help to increase the user's call function and save the use cost.

In view of the above problems, the present invention provides a mobile device and a method thereof, and more particularly, a mobile device capable of three-way calling and a method thereof, so that a three-party call can be performed without additional services provided by a mobile communication system provider. .

The invention provides a mobile device capable of three-way calling, comprising a signal processing unit, a first communication module, a first switch, a second communication module, a second switch, a microphone, a third switch, a speaker device, and a fourth switch And the control interface.

The first communication module is coupled to the signal processing unit via the first switch. The first communication module transmits/receives the first communication signal, and connects the communication between the first party and the second party. The second communication module is coupled to the signal processing unit via the second switch. The second communication module transmits/receives the second communication signal and enables communication between the first party and the third party. The microphone is coupled to the signal processing unit via a third switch. The microphone receives the sound wave signal and converts it into an electrical microphone receiving signal, which is transmitted to the signal processing unit. The speaker device is coupled to the signal processing unit via the fourth switch. The speaker device plays the sound signal from the signal processing unit. The control interface is coupled to the signal processing unit. control The interface sends a control signal to the signal processing unit. The signal processing unit determines the opening and closing of the first switch, the second switch, the third switch, and the fourth switch according to the control signal. .

The present invention further provides a method for making a three-party call, which is applicable to a mobile device, and includes the following steps.

The first step is to transmit/receive a first communication signal by the first communication module.
