Description

One-machine multi-card wireless mobile phone and its realization method

[technical field]

The invention relates to radio mobile phone technology, in particular to a multi-card wireless mobile phone in one machine and a method for realizing the simultaneous use of multiple cards in one machine.

[Background technique]

Currently there are two main standards applicable to 2G wireless devices: one is GSM/GPRS/EDGE, and the other is CDMA20001X. The GSM standard defines that mobile phones use SIM cards to work, while CDMA20001X defines that mobile phones use RUIM cards. In addition, emerging WCDMA, EVDO, TD-SCDMA and other 3G standards and future mobile phone standards also use cards of their corresponding technical standards. These mobile phone cards are all detachable, and the user's unique mobile phone number and personal information are stored thereon. That is: most of the existing mobile phones are one machine, one card and one number. With the busy business of people from all walks of life, or wishing to separate the phone calls of business contacts from those of friends and relatives, people often carry more than two phone cards with them. When needed, the phone cards to be used are inserted into the mobile phone for use, but they are pulled out. The card number of the phone is turned off immediately and can no longer receive incoming calls or messages, causing a lot of inconvenience and even serious economic losses. So many people carry two independent phones with them to solve the above problems, but the two phones are not easy to carry, easy to lose, and can increase the cost of the user.

There is also a dual-mode mobile phone on the market, which can install a SIM card and a RUIM card at the same time, but only one card can be used at the same time, that is, when one card is used, the other card is in the Off state. Therefore, this technology does not fundamentally solve the defects of the prior art.

[Content of the invention]

The object of the present invention is to provide a kind of multi-card type wireless mobile phone and its realization method that can overcome above-mentioned prior art defect.

The technical solution adopted by the present invention to solve the technical problems is: a multi-card wireless mobile phone, which at least includes two phone decks, and the mobile phone also includes a baseband processor and a selection switch; the telephone deck is electrically connected to the corresponding baseband processor; the at least two baseband processors are electrically connected to the public radio transceiver through the selection switch, and communicate with the service base station through the antenna, and in the standby state, the The selection switch is frequently switched between the at least two baseband processors to transmit signals from the common radio transceiver; when the baseband processor receives a specific signal, it sends a switching control signal to the selection switch, and the control selection switch is connected within the dialogue period. pass the baseband processor to the radio transceiver.

As an implementation manner of the present invention, the at least two baseband processors are baseband processors of the same technical standard.

As another implementation manner of the present invention, the at least two baseband processors are baseband processors of different technical standards.

As an implementation manner of the present invention, the at least one baseband processor is connected in parallel to a common display circuit and shares the display circuit.

As another embodiment of the present invention, the one-device multi-card wireless mobile circuit includes display circuits having the same number as the card slots; and the baseband processors are respectively electrically connected to the corresponding display circuits.

In the present invention, each baseband processor is configured with an address book storage unit.

As an improvement of the present invention, the at least two baseband processors share an address book storage unit.

The present invention also provides a method capable of realizing the above-mentioned one-machine multi-card wireless mobile phone: in the standby state, the selection switch is frequently switched between the at least two baseband processors to transmit information from the public radio transceiver. signal; when the baseband processor receives a specific signal, it sends a switching control signal to the selector switch, and controls the selector switch to connect the baseband processor and the radio transceiver during the dialogue period.

Further, the specific signal is one of the following signals: an incoming call signal whose target address is the corresponding card number, an information signal whose target address is the corresponding card number, a request to send dial information signal, and a request to send information signal.

Further, the baseband processor judges whether the signal is processed by itself by identifying the identification mark in the signal from the radio transceiver.

The beneficial effect of the present invention is: mobile phone user can use according to actual needs and can install at least two mobile phones under a kind of technology standard card, also can dispose the mobile phone that has different kind of technology standard (GSM, CDMA20001X etc.) card at the same time, The function of one machine with multiple cards and multiple numbers is realized, and the at least two card numbers can be used at the same time, which fundamentally overcomes the defects of the prior art.

[Description of drawings]

Fig. 1 is a schematic diagram of the circuit structure of a multi-card mobile phone of the present invention.

[Detailed ways]

The present invention will be further elaborated below according to the drawings and specific embodiments.

The wireless mobile phone of the present invention is similar to the existing mobile phone in appearance, and both include a casing, a display screen, a microphone, a loudspeaker, a button circuit and an antenna (also can be built in). The battery can be disposed in the casing, or can be a part of the casing itself. The difference is that the housing of the wireless mobile phone in the present invention includes: a radio transceiver, at least two phone decks, baseband processors with the same number as the phone decks and a selection switch S. Wherein, the telephone deck is electrically connected with the corresponding baseband processor. The above at least two baseband processors are electrically connected to the common radio transceiver through the selection switch S, and then communicate with the corresponding serving base station through the antenna A. The at least two baseband processors share a microphone, a loudspeaker, a button circuit and a battery in addition to a radio transceiver. Figure 1 shows a schematic diagram of the circuit structure of two baseband processors as an example.

Because each phone deck corresponds to a baseband processor, the wireless mobile phone of the present invention can configure all baseband processors as the same system, such as all being the GSM system, or all being the CDMA20001X system, or WCDMA, EVDO, TD-SCDMA format. It is also possible to configure the baseband processors to be of different standards, for example, one for the GSM standard, one for the CDMA standard, and the rest for the VCDMA standard. Therefore, the combination of one machine, multiple cards, multiple numbers, and multiple formats can be freely configured according to user needs.

The working principle of the one-machine multi-card wireless mobile phone of the present invention is described below by taking two phone decks and two baseband processors as an example:

After the mobile phone is turned on, the selection switch S is frequently switched between the two baseband processors to transmit signals from the public radio transceiver, and conduct identity verification and positioning communication with the serving base station through the antenna A. When the mobile phone receives the incoming call signal and information signal (short message, EMAIL, etc.) from the base station, the selection switch S switches frequently to send the signal to the two baseband processors. One of the baseband processors, such as baseband processor 1, judges that the signal is processed by itself by identifying the identification mark in the signal, and sends a switching control message to the selection switch S, and controls the selection switch S to connect the baseband processor during the dialogue. 1 with the radio transceiver. When the baseband processor 1 ends the conversation or receives the information signal, it sends a control signal to the selection switch S, and the control selection switch S is frequently switched between the two baseband processors again. When the user needs to use a card to make a call or send a message, a request switching control signal is sent to the corresponding baseband processor through the button circuit (that is, a request to send a dial-up information signal, a request to send an information signal, or other equivalent signals that need to communicate with the base station ), the baseband processor sends a switching control message to the selector switch S, and controls the selector switch S to connect the baseband processor and the radio transceiver during the call or during the information transmission. When the baseband processor ends the call or sends the information signal, it sends a control signal to the selection switch S, and the control selection switch S is frequently switched between the two baseband processors again.

Like this, in the standby state, the card that is installed on the mobile phone can be used normally, carries out making and receiving calls or sending and receiving messages. When one card is in the talking state, the other card is still in the standby state. When there is a call to the other card, the call will be regarded as call waiting. For other applications related to mobile phones, there is no impact. For example, a CDMA2000 mobile phone can install two (or more) RUIM cards with different numbers at the same time. Users can receive calls or short messages from corresponding numbers at the same time, and can choose to use any number to make calls. Such a mobile phone can save the user from carrying a plurality of mobile phones at the same time. When traveling, users can choose to use a SIM/RUIM card's local service to avoid roaming services, but at the same time receive calls from other cards. It is very convenient to use.

In one embodiment of the present invention, multiple baseband processors are connected in parallel to control one display circuit. After booting, only the default information is displayed, for example, only the information of the default card number is displayed. When it is necessary to switch to another card number, it will automatically switch and display the information of another card number according to the command of the baseband processor.

In another embodiment of the present invention, multiple baseband processors respectively control a display circuit, and the display screen displays information corresponding to the card number in split screens. The display screen can also only display the information of one card number, and when it needs to switch to another card number, it will automatically switch and display the information of another card number according to the command of the baseband processor.

In the present invention, an address book storage unit may be configured for each baseband processor, and each address book storage unit stores the number associated with the corresponding card. All baseband processors may also share one address book storage unit, which is convenient for users.
