In order to better illustrate the method described in the present invention, the Android operating system is taken as an example for illustration. Wherein, in order to implement the monitoring of the system network call status, the present invention needs to set a background service in the system based on the Root authority (unless the Root authority has been opened), so that the background service can communicate with the system based on the Binder mechanism.

As we all know, Root authority refers to the system administrator authority of Unix-like operating systems (including Linux, Android), similar to the Administrator (administrator) authority in Windows (Windows) system; Root authority can access and modify almost All files (Android system files and user files, excluding ROM). In view of this, the industry provides a variety of privilege escalation schemes to obtain the Root privilege of the Android system, realize user privilege escalation, and achieve the purpose of fully controlling the operating system. These privilege escalation schemes, according to the life cycle of privileges after privilege escalation, include permanent root privileges and temporary root privileges. As the name implies, in the case of permanent root privileges, once the application is root-authorized, there is no need to perform root privilege escalation in the future; and In the case of temporary root authority, the life cycle of the authority is only a process from booting to shutting down of the operating system, and rooting is still required for the next boot.

Regardless of the root method adopted, the basic principle of privilege escalation is to implant su to the system to receive permission requests, and then combine the SuperUser.apk application to realize human-computer interaction. Through the mutual interaction between su and SuperUser.apk Cooperate to achieve effective rights management. The present invention acquires Root authority so as to set background services in the system to monitor the network call behavior of the system, but the Root method adopted is not a limitation of the present invention.

Based on the above principles, taking the Android system as an example, a method for calling with a dual-card dual-standby mobile phone terminal based on call transfer provided by the present invention is described in detail. Referring to Figure 1, the specific steps are as follows:

S101, monitor whether the two numbers of the mobile terminal are open for network calls;

The monitoring of whether the two numbers of the mobile terminal are enabled for network calls is specifically implemented by a pre-registered background service. The background service referred to in this embodiment refers to a program module pre-implemented by this method, which runs in the memory and registers with the system after the corresponding main process in the memory realizes the aforementioned power-escalation operation. A communication service process. The background service is based on the Binder mechanism provided by the Android system, registers with the System Manager, and establishes a C/S architecture communication channel between the background service and its monitoring network call process through the inherent Binder mechanism provided by Android. Specifically, after obtaining the Root authority of the system, in order to facilitate subsequent monitoring of other processes in the system and related operating functions, the present invention first starts the main process that has obtained the Root authority and is instantiated and run by this method. process, insert the background service in the system through the main process, for example, the insertion operation can be realized by calling the function ServiceManager. The background service thus becomes the service process at the bottom level of the system. It should be noted that the background service process has become a system-level service process through the above configuration, and its authority is obviously higher than that of other user-level service processes or application processes. Therefore, the background service process can be used as a basis for communication. Other processes that call it provide communication guarantee and complete the communication connection between the system and other processes that call it. Therefore, the background service process has the ability to communicate with the network call process it monitors, and the communication between the two is based on the Binder mechanism. This communication method has the characteristics of fast and stable. The background service process is mainly used to implement the monitoring of the network call process of the system, so as to know in time whether the mobile terminal starts the network call based on the user's instruction, so as to facilitate the execution of subsequent incoming call transfer steps.

Wherein, the monitoring of the network call specifically refers to the monitoring of the network communication behavior of the corresponding communication software, and the communication software uses the data traffic or WiFi data of one of the numbers of the mobile phone terminal in the dual card dual standby mode to conduct network communication. communication. Such as WeChat, QQ, Yixin, etc., when the network call is enabled, these communication software will call back the corresponding function interface of the system, such as the camera interface during video call, the audio interface during voice call, etc., at these function interfaces Set up a listener, trigger the listener when these function interfaces are called through the network call process, and transmit the message of starting the network call to the background service by calling back the related functions of the background service. In this way, the monitoring of whether the two numbers of the mobile phone terminal in the dual-card dual-standby mode is enabled for network calls can be realized.

It should be noted that the Internet call in the present invention specifically refers to a voice or video call through the Internet connected to the Internet by means of mobile data traffic, WiFi, etc., and the implementation of the Internet call is not a limitation on the method of the present invention.

S102. When any number opens the network call, set the call forwarding, so that when the number has a mobile phone call, transfer it to another number of the mobile terminal, so as to maintain the network call state of the number;

When any number of the mobile terminal is monitored to open the network call, set the call forwarding to prevent the interruption of the network call when the network is switched to 2G when there is an incoming call, and transfer it to another number of the mobile terminal to maintain the mobile phone The network call status of the terminal.

Preferably, after the mobile terminal is monitored to open the network call, it also includes detecting the current network type of the mobile terminal, and the specific code is as follows:

int getNetType(Context context)

{

int netType = -1;

ConnectivityManager conMgr = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);

NetworkInfo networkInfo = conMgr.getActiveNetworkInfo();

if(networkInfo==null)

{

return netType;

}

netType = networkInfo. getType();

}

When the netType is ConnectivityManager.TYPE_WIFI, it is judged that the current mobile terminal is connected to the Internet through WiFi. Since WiFi communicates based on the principle of wireless LAN, it will not be affected at all when there is an incoming call, so the network call will not be interrupted. Therefore, in this case The network call can be maintained without setting call forwarding.

When the netType is ConnectivityManager.TYPE_MOBILE, it is determined that the current mobile terminal is connected to the Internet through data traffic. Since data traffic and incoming calls are based on TD-SCDMA technology for communication, and these two services cannot be performed concurrently, the priority of the incoming call service is high. For data traffic, when there is an incoming call, the data traffic based on 4G communication will be switched to voice calls based on 2G, so the network will be disconnected at this time, resulting in the interruption of the user's current network call. Therefore, in this case, call forwarding is set to prohibit the number that is currently making an Internet call from receiving an incoming call and causing the network to be disconnected.

Wherein, the setting of the call forwarding is executed before the start of the network call is detected and the call is started, so that the call forwarding can really play the role of intercepting the incoming call, and the telephone number for making the network call is prohibited from receiving the incoming call.

The call forwarding generally includes unconditional call forwarding and conditional call forwarding, wherein the conditional call forwarding includes busy call forwarding, no answer call forwarding, and unreachable call forwarding. Wherein, the call forwarding in the present invention specifically refers to unconditional call forwarding, that is, in the embodiment of the present invention, any incoming call is unconditionally forwarded as long as the mobile terminal is in the network call state.

The call forwarding is specifically operated by the mobile communication operator according to the setting of the mobile terminal, and the incoming call is directly forwarded to the target number set by the call forwarding. Since the current domestic mobile communication operators include three, namely China Mobile, China Unicom, and China Telecom, each operator has different operating instructions for setting call forwarding, so the specific realization of the call forwarding is set for the three mobile phone terminals The codes are as follows:

1. The command for China Mobile to set unconditional call forwarding is **21*phone number#

Intent callIntent = new Intent(Intent.ACTION_CALL, Uri.parse(Uri.encode("tel:**21*specific number#")));

startActivity(callIntent);

2. The command of China Unicom to set unconditional call forwarding is *72+telephone number+send

Intent callIntent = new Intent(Intent.ACTION_CALL, Uri.parse(Uri.encode("tel:*72+specific number+send")));

startActivity(callIntent);

3. China Telecom sets the command of unconditional call forwarding as *72+telephone number

Intent callIntent＝new Intent(Intent.ACTION_CALL,Uri.parse(Uri.encode("tel:*72+specific number")))

startActivity(callIntent);

According to the state of the SIM card in the mobile terminal, the mobile terminal can be divided into a single-card single-standby mode, a dual-card dual-standby mode, a dual-card single-standby mode, and the like. The single-card single-standby mode refers to one SIM card; the dual-card dual-standby mode means that two SIM cards can be used at the same time without interfering with each other; the dual-card single-standby mode refers to two SIM cards, but the other A card is powered off.

Wherein, the above-mentioned specific number specifically refers to the set call forwarding number. In a specific embodiment, the specific number is a phone number in a non-network call state in a dual-card dual-standby mobile terminal.

The solution described in the embodiment of the present invention is mainly aimed at mobile terminals in dual-card dual-standby mode, and the specific number is set as the number corresponding to one of the dual-cards. When the user makes a network call through one of the cards, the other card is in standby mode. The two are independent of each other and do not interfere with each other. The number corresponding to the card in the status can prevent the network call from being interrupted by the incoming call, and it is also convenient for the user to choose to answer or reject the incoming call transferred to another card number. In other embodiments, the present invention also provides a mobile secretary station, which transfers incoming calls to the preset secretary station number, and the secretary station answers the call and sends the content of the call to the mobile phone as a short message. The secretary station also provides services such as machine owner message query SMS, service reservation, password setting and reminder, so as to provide users with more intelligent and convenient services.

In other embodiments, the present invention also includes providing a network call interface for implementing voice or video calls based on the Internet. Wherein, the network call interface includes an address book, a voice call button, a video call button, and the like. The user selects any friend in the address book, and sends an instruction to initiate an internet call by clicking a voice call button or a video call button, and the internet call interface receives the instruction to initiate an internet call to the corresponding friend. Through the network call interface, it is more convenient to monitor whether the mobile terminal is in the open network call, so as to set the incoming call transfer for the mobile terminal more timely and conveniently.

In other embodiments, the present invention also includes providing a mobile call dialing interface, which is used to implement mobile call dialing based on replacing the dialing keyboard that comes with the mobile phone terminal system. Wherein, the mobile call dialing interface includes a dialing keyboard, a telephone number display area, an address book, a dialing key, a hang up key, etc. Through the dialing interface, a number in the address book can be selected or a number can be directly input for dialing. When a mobile call incoming call is transferred to another number of the dual-card dual-standby mobile phone terminal, the incoming call is displayed on the mobile call dial interface, specifically to display the incoming call number, and a ringing prompt is made, and the user chooses whether to answer the call . However, because the incoming call is transferred to another number that is not in the network call, the two do not interfere with each other, so the incoming call can be received by another number that is not in the network call while maintaining the network call. In addition, based on this interface, it is convenient for users to make calls, and at the same time, a third-party account is established for users, which facilitates the combination of mobile calls with more application programs, and realizes more extensive and convenient applications.

S103. Cancel the call forwarding setting when the network call ends.

After the mobile terminal is set with unconditional call forwarding, although the incoming call of the number of the dual-card dual-standby mobile terminal in the network call is transferred to another number, it is still inconvenient for both numbers to answer the call. Therefore, when the network call performed by the mobile terminal ends, the call forwarding set on the mobile terminal should be canceled in time.

The call forwarding is specifically operated by the mobile communication operator according to the setting of the mobile terminal, and the incoming call is directly forwarded to the target number set by the call forwarding. Since the current domestic mobile communication operators include three, namely China Mobile, China Unicom, and China Telecom, each operator has different operating instructions for setting call forwarding, so cancel the setting of the specific call forwarding instructions for the three mobile phone terminals. The implementation codes are as follows:

1. The order for China Mobile to set unconditional call forwarding is ##21#

Intent callIntent = new Intent(Intent.ACTION_CALL, Uri.parse(Uri.encode("tel:##21#")));

startActivity(callIntent);

2. China Unicom sets the command of unconditional call forwarding as *720+send

Intent callIntent = new Intent(Intent. ACTION_CALL, Uri. parse(Uri. encode("tel:*720+send")));

startActivity(callIntent);

3. The command of China Telecom to set unconditional call forwarding is *720

Intent callIntent = new Intent(Intent. ACTION_CALL, Uri. parse(Uri. encode("tel:*720")));

startActivity(callIntent);

Based on the above method, the mobile phone terminal that ends the network call cancels the call transfer, and restores to the original state where it can receive calls.

With reference to shown in Fig. 2, based on modular thinking, the principle of the method of the present invention is further described, and a dual-card dual-standby mobile terminal communication device based on call transfer is provided, including a monitoring module 11, a call transfer setting module 12, a call transfer The cancellation module 13, and the first call module 14, the second call module 15, the network type detection module 16, and the incoming call reminder module 17 in some alternative embodiments, wherein,

Monitoring module 11: configured to monitor whether the two numbers of the mobile phone terminal open the network call;

The monitoring module 11 is specifically executed by a pre-registered background service. The background service referred to in this embodiment refers to a program module pre-implemented by this method, which runs in the memory and registers with the system after the corresponding main process in the memory realizes the aforementioned power-escalation operation. A communication service process. The background service is based on the Binder mechanism provided by the Android system, registers with the System Manager, and establishes a C/S architecture communication channel between the background service and its monitoring network call process through the inherent Binder mechanism provided by Android. Specifically, after obtaining the Root authority of the system, in order to facilitate subsequent monitoring of other processes in the system and related operating functions, the present invention first starts the main process that has obtained the Root authority and is instantiated and run by this method. process, insert the background service in the system through the main process, for example, the insertion operation can be realized by calling the function ServiceManager. The background service thus becomes the service process at the bottom level of the system. It should be noted that the background service process has become a system-level service process through the above configuration, and its authority is obviously higher than that of other user-level service processes or application processes. Therefore, the background service process can be used as a basis for communication. Other processes that call it provide communication guarantee and complete the communication connection between the system and other processes that call it. Therefore, the background service process has the ability to communicate with the network call process it monitors, and the communication between the two is based on the Binder mechanism. This communication method has the characteristics of fast and stable. The background service process is mainly used to monitor the network call process of the system, so as to know in time whether the mobile terminal starts the network call based on the user's instruction, so as to facilitate the execution of the subsequent incoming call transfer setting module.

Wherein, the monitoring of the network call specifically refers to the monitoring of the network communication behavior of the corresponding communication software, and the communication software uses the data traffic or WiFi data of one of the numbers of the mobile phone terminal in the dual card dual standby mode to conduct network communication. communication. Such as WeChat, QQ, Yixin, etc., when the network call is enabled, these communication software will call back the corresponding function interface of the system, such as the camera interface during video call, the audio interface during voice call, etc., at these function interfaces Set up a listener, trigger the listener when these function interfaces are called through the network call process, and transmit the message of starting the network call to the background service by calling back the related functions of the background service. In this way, the monitoring of whether the two numbers of the mobile phone terminal in the dual-card dual-standby mode is enabled for network calls can be realized.

It should be noted that the Internet call in the present invention specifically refers to a voice or video call through the Internet connected to the Internet by means of mobile data traffic, WiFi, etc., and the implementation of the Internet call is not a limitation on the method of the present invention.

Call transfer setting module 12: configured to set call transfer when the mobile phone terminal is monitored to open the network call, so that when there is a mobile call incoming call, it will be transferred to a specific number, thereby maintaining the network call state;

When any number of the mobile terminal is monitored to open the network call, set the call forwarding to prevent the interruption of the network call when the network is switched to 2G when there is an incoming call, and transfer it to another number of the mobile terminal to maintain the mobile phone The network call status of the terminal.

Preferably, after listening to the mobile terminal to open the network call, it also includes a network type detection module 16, which is used to detect the current network type of the mobile terminal, and the specific codes are as follows:

int getNetType(Context context)

{

int netType = -1;

ConnectivityManager conMgr = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);

NetworkInfo networkInfo = conMgr.getActiveNetworkInfo();

if(networkInfo==null)

{

return netType;

}

netType = networkInfo. getType();

}

When the netType is ConnectivityManager.TYPE_WIFI, it is judged that the current mobile terminal is connected to the Internet through WiFi. Since WiFi communicates based on the principle of wireless LAN, it will not be affected at all when there is an incoming call, so the network call will not be interrupted. Therefore, in this case The network call can be maintained without setting call forwarding.

When the netType is ConnectivityManager.TYPE_MOBILE, it is determined that the current mobile terminal is connected to the Internet through data traffic. Since data traffic and incoming calls are based on TD-SCDMA technology for communication, and these two services cannot be performed concurrently, the priority of the incoming call service is high. For data traffic, when there is an incoming call, the data traffic based on 4G communication will be switched to voice calls based on 2G, so the network will be disconnected at this time, resulting in the interruption of the user's current network call. Therefore, in this case, call forwarding is set to prevent the mobile terminal from receiving incoming calls and causing network disconnection.

Wherein, the setting of the call forwarding is executed before the network call is detected and started, so that the call forwarding can really play the role of intercepting incoming calls, and the mobile terminal is prohibited from receiving incoming calls.

The call forwarding generally includes unconditional call forwarding and conditional call forwarding, wherein the conditional call forwarding includes busy call forwarding, no answer call forwarding, and unreachable call forwarding. Wherein, the call forwarding in the present invention specifically refers to unconditional call forwarding, that is, in the embodiment of the present invention, any incoming call is unconditionally forwarded as long as the mobile terminal is in the network call state.

The call forwarding is specifically operated by the mobile communication operator according to the setting of the mobile terminal, and the incoming call is directly forwarded to the target number set by the call forwarding. Because the current domestic mobile communication operators include three, respectively China Mobile, China Unicom, and China Telecom, each operator sets different operating instructions for call forwarding, so the call forwarding setting module 12 sets the above three mobile phone terminals. The specific implementation codes of call transfer are as follows:

1. The command for China Mobile to set unconditional call forwarding is **21*phone number#

Intent callIntent = new Intent(Intent.ACTION_CALL, Uri.parse(Uri.encode("tel:**21*specific number#")));

startActivity(callIntent);

2. The command of China Unicom to set unconditional call forwarding is *72+telephone number+send

startActivity(callIntent);

3. China Telecom sets the command of unconditional call forwarding as *72+telephone number

Intent callIntent＝new Intent(Intent.ACTION_CALL,Uri.parse(Uri.encode("tel:*72+specific number")))

startActivity(callIntent);

The specific number can also be an empty number. When the incoming call is not an unfamiliar number in the address book or a number in the blacklist set by the user, the incoming call will be transferred to the empty number, and the incoming call will be prompted to dial the number Leave an empty number to reject such incoming calls. Further, the embodiment of the present invention also provides a mobile secretary station, which transfers incoming calls to the preset secretary station number, and the secretary station answers the call and sends the content of the call to the mobile phone as a short message. The secretary station also provides services such as message query SMS for the owner, appointment service, password setting and reminder, so as to provide users with more intelligent and convenient services.

Preferably, for a mobile phone terminal in dual-card dual-standby mode, the specific number is set as the number corresponding to one of the dual-cards. When the user makes a network call through one of the cards, the other card is in standby mode. The two are independent of each other and do not interfere with each other. The number corresponding to the card in the status can prevent the network call from being interrupted by the incoming call, and it is also convenient for the user to choose to answer or reject the incoming call transferred to another card number. Further, the embodiment of the present invention also provides a mobile secretary station, which transfers incoming calls to the preset secretary station number, and the secretary station answers the call and sends the content of the call to the mobile phone as a short message. The secretary station also provides services such as machine owner message query SMS, service reservation, password setting and reminder, so as to provide users with more intelligent and convenient services.

In other embodiments, the present invention further includes a first call module 14, which provides a network call interface for implementing voice or video calls based on the Internet. Wherein, the network call interface includes an address book, a voice call button, a video call button, and the like. The user selects any friend in the address book, and sends an instruction to initiate an internet call by clicking a voice call button or a video call button, and the internet call interface receives the instruction to initiate an internet call to the corresponding friend. Through the network call interface, it is more convenient to monitor whether the mobile terminal is in the open network call, so as to set the incoming call transfer for the mobile terminal more timely and conveniently.

In other embodiments, the present invention further includes a second call module 15, which provides a mobile call dialing interface for implementing mobile call dialing based on replacing the dialing keyboard that comes with the mobile phone terminal system. Wherein, the mobile call dialing interface includes a dialing keyboard, a telephone number display area, an address book, a dialing key, a hang up key, etc. Through the dialing interface, a number in the address book can be selected or a number can be directly input for dialing. When the mobile call incoming call is transferred to another number of the dual-card dual-standby mobile phone terminal, the incoming call is displayed on the mobile call dialing interface by the incoming call reminder module 17, specifically for displaying the incoming call number, and ringing for prompting, It is up to the user to choose whether to answer or not. However, since the incoming call is transferred to another number that is not in the network call, the two do not interfere with each other, so the incoming call can be received by another number that is not in the network call while maintaining the network call. In addition, based on this interface, it is convenient for users to make calls, and at the same time, a third-party account is established for users, which facilitates the combination of mobile calls with more application programs, and realizes more extensive and convenient applications.

Call forwarding cancellation module 13: configured to cancel the call forwarding setting when the network call ends.

After the mobile terminal is set with unconditional call forwarding, although the incoming call of the number of the dual-card dual-standby mobile terminal in the network call is transferred to another number, it is still inconvenient for both numbers to answer the call. Therefore, when the network call performed by the mobile terminal ends, the call forwarding set on the mobile terminal should be canceled in time.

The call forwarding is specifically operated by the mobile communication operator according to the setting of the mobile terminal, and the incoming call is directly forwarded to the target number set by the call forwarding. Since the current domestic mobile communication operators include three, namely China Mobile, China Unicom, and China Telecom, each operator has different operating instructions for setting call forwarding, so the call forwarding cancellation module 13 cancels all settings for these three mobile phone terminals. The specific implementation codes of the above call transfer are as follows:

1. The order for China Mobile to set unconditional call forwarding is ##21#

Intent callIntent = new Intent(Intent.ACTION_CALL, Uri.parse(Uri.encode("tel:##21#")));

startActivity(callIntent);

2. China Unicom sets the command of unconditional call forwarding as *720+send

Intent callIntent = new Intent(Intent. ACTION_CALL, Uri. parse(Uri. encode("tel:*720+send")));

startActivity(callIntent);

3. The command of China Telecom to set unconditional call forwarding is *720

Intent callIntent = new Intent(Intent. ACTION_CALL, Uri. parse(Uri. encode("tel:*720")));

startActivity(callIntent);

Based on the above method, the mobile phone terminal that ends the network call cancels the call transfer, and restores to the original state where it can receive calls.
