The present document relates to the field of communication technologies, and more particularly, to a method for transferring a call on a mobile terminal and a mobile terminal thereof.
Although a related dual-card dual-standby dual-pass mobile terminal can achieve a three-party call under two communication cards, when two parties want to talk directly during the call, they must hang up and then call each other directly to talk with each other directly. For example, Xiao Wang establishes a call connection with Xiao Hong via a first communication card, and also establishes a call connection with Xiao Ming via a second communication card, and if Xiao Hong and Xiao Ming want to chat with each other, they can only do so by respectively hanging up the call connections with Xiao Wang and redial each other's phone number to chat, and when the Xiao Hong and Xiao Ming don't hang up the call connections with Xiao Wang respectively, the call of the Xiao Hong and Xiao Ming cannot be directly transferred by Xiao Wang to implement the direct call between the Xiao Hong and Xiao Ming. Also, if Xiao Hong is looking for Xiao Ming through the first card, the terminal may directly dial Xiao Ming's phone number through the second card and directly transfer the call to Xiao Hong without disclosing the Xiao Ming's phone number or hanging up the call. With the increasing number of dual-card dual-standby dual-pass terminals, this call transferring function will become the urgent needs of the users.

The embodiment of the present document can directly perform a call connection on the opposite-end calls through a call transferring method without hanging up the current call connections when two communication cards respectively establish call connections according to user demands, so as to easily, simply and quickly implement the call transferring function in a mobile terminal.
Hereinafter, in conjunction with the accompanying drawings and embodiments, the technical solution of the present document will be further described. It should be understood that the specific embodiments described herein are only intended to explain rather than limit the present document.
It should be emphasized that: the flow chart shown in
the method for transferring a call in a mobile terminal provided in the present embodiment comprises:
in step S10, the mobile terminal controls its two communication cards to respectively establish a first call connection and a second call connection;
In the present embodiment, the two communication cards may belong to the same network standard, which can be any one of GSM (Global System Of Mobile Communication), WCDMA (Wideband Code Division Multiple Access), CDMA (Code division Multiple Access), TD-SCDMA (Time division-synchronous Code division Multiple Access) and LTE (long Term Evolution), or may respectively belong to any two of the GSM, the CDMA, the WCDMA, the TD-SCDMA and the LTE. For example, the mobile terminal establishes a first call connection through the GSM network standard of the first communication card and establishes a second call connection through the CDMA network standard of the second communication card, or the mobile terminal establishes a first call connection through the GSM network standard of the first communication card, and establishes a second call connection through the GSM network standard of the second communication card.
In step S20, upon receiving a call transferring instruction, the mobile terminal obtains downlink channel data of the first call connection and the second call connection;
upon receiving the call transferring instruction, the mobile terminal has already established two call connections through the two communication cards. The call state corresponding to the first call connection is the call hold state, that is, call waiting state, the call state corresponding to the second call connection is the call activated state, that is, normal call state. According to the user needs, it may also switch between these two states. For example, when the user wants to switch from the call of the second call connection to the first call connection, it transmits a Retrieve instruction to the network side of the first communication card and transmits a Hold instruction to the network side of the second communication card, to retrieve the first call connection of the first communication card; of course, the user can also switch the call of the first call connection to the second call connection, the processing procedure is the same and is not repeated here.
After receiving the call transferring instruction, it sends a Retrieve instruction to the corresponding first communication card or second communication card to enable the first communication card or the second communication card to stay in the call activated state, that is, the normal call state. The mobile terminal obtains the downlink channel data of the first call connection established through the first communication card and the downlink channel data of the second call connection established through the second communication card.
In step S30, the mobile terminal takes the obtained downlink channel data of the first call connection as the uplink channel data of the second call connection, and takes the obtained downlink channel data of the second call connection as the uplink channel data of the first call connection, and shields the audio data input/output unit in the mobile terminal.
In the GSM and CDMA network standards, for example, the mobile terminal controls its two communication cards to establish the first call connection and the second call connection respectively through the GSM and CDMA networks, upon receiving a call transferring instruction, the mobile terminal takes the downlink channel data received from the GSM network side as uplink channel data of the CDMA network side to transmit, and takes the downlink channel data received from the CDMA network side as uplink channel data of the GSM network side to transmit.
The audio data input/output unit is in the shielded state, that is, it does not perform any data processing, which well protects the privacy of the opposite-end of call transferring. The audio data input/output unit comprises: Mic (Microphone), Receiver, Speaker and other audio data input/output units with the same function.
Preferably, in the call transferring process, when the mobile terminal receives a call termination instruction sent by the user through the present terminal, the mobile terminal controls the first communication card and the second communication card to disconnect the established first call connection and second call connection; or the mobile terminal controls the second call connection of the second communication card to be disconnected when the first call connection of the first communication card is terminated, or the mobile terminal controls the first call connection of the first communication card to be disconnected when the second call connection is terminated.
In order to facilitate the implementation of the call transferring in the dual-card single-network mode or the dual-card dual-network mode, two sets of baseband radio frequency provided in the embodiment of the present document can process the uplink channel data of the calls respectively established through two communication cards without performing any changes to the network side.
The present embodiment can directly perform a call connection on the opposite-end calls through a call transferring method without hanging up the current call connections when two communication cards respectively establish call connections according to user demands, so as to easily, simply and quickly implement the call transferring function in a mobile terminal.

For example, the mobile terminal establishes a first call connection through the GSM network standard of the first communication card and the mobile terminal establishes a second call connection through the CDMA network standard of the second communication card when receiving a call transferring instruction, or the mobile terminal establishes a first call connection through the GSM network standard of the first communication card, and the mobile terminal establishes a second call connection through the GSM network standard of the second communication card when receiving a call transferring instruction.
The mobile terminal controls its first communication card to establish a first call connection; upon receiving the call transferring instruction, the mobile terminal controls its second communication card to establish a second call connection. In this case the mobile terminal has already established two call connections through the first communication card and the second communication card respectively. The call state corresponding to the first call connection and the call state corresponding to the second call connection are the call activated state, that is, the normal call state.
When the mobile terminal controls its second communication card to establish the second call connection, the mobile terminal obtains the downlink channel data of the first call connection established through the first communication card as well as the downlink channel data of the second call connection established through the second communication card.
In step S130, the mobile terminal takes the obtained downlink channel data of the first call connection as the uplink channel data of the second call connection and the obtained downlink channel data of the second call connection as the uplink channel data of the first call connection, and shields the audio data input/output unit in the mobile terminal.
In the GSM and CDMA network standards, for example, the mobile terminal controls its first communication card to establish the first call connection through the GSM network, and controls its second communication card to establish the second call connection through the CDMA network when receiving a call transferring instruction, and it obtains the downlink channel data of the first call connection established through the first communication card and the downlink channel data of the second call connection established through the second communication card; the mobile terminal takes the downlink channel data received from the GSM network side as uplink channel data of the CDMA network side to transmit, and takes the downlink channel data received from the CDMA network side as uplink channel data of the GSM network side to transmit.
The audio data input/output unit is in the shielded state, that is, it does not perform any data processing, which well protects the privacy of the opposite-end of call transferring. The audio data input/output unit comprises: Mic (Microphone), Receiver, Speaker and other audio data input/output units with the same function.
Furthermore, in the call transferring process, when the mobile terminal receives a call termination instruction sent by the user through the present terminal, the mobile terminal controls the first communication card and the second communication card to disconnect the established first call connection and second call connection; or the mobile terminal controls the second call connection of the second communication card to be disconnected when the first call connection of the first communication card is terminated, or the mobile terminal controls the first call connection of the first communication card to be disconnected when the second call connection is terminated.

The call state corresponding to the first call connection is the call hold state, that is, the call waiting state, and the call state corresponding to the second call connection is the call activated state, that is, the normal call state. According to the user needs, it can also switch between these two states. For example, when the user wants to switch from the call of the second call connection to the first call connection, it transmits a Retrieve instruction to the network side of the first communication card and transmits a Hold instruction to the network side of the second communication card to retrieve the first call connection of the first communication card; of course, the user can also switch the call of the first call connection to the second call connection, the processing procedure is same and is not repeated here.
After receiving the call transferring instruction, it is to send a Retrieve instruction to the corresponding first communication card or second communication card to enable the first communication card or second communication card to stay in the call activated state, that is the normal call state. The obtaining module 20 obtains the downlink channel data of the first call connection established through the first communication card and the downlink channel data of the second call connection established through the second communication card.
