detailed description

In order to make the technical problems solved by the present invention, the technical solutions adopted and the technical effects achieved clearer, the technical solutions of the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only the technical solutions of the present invention. Some, but not all, embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts belong to the protection scope of the present invention.

Embodiment one

Referring to Figure 1, a call method under a hybrid network system, including:

S101. Detect a network environment value of the terminal in an environment where the network environment value includes a network standard and a signal strength under the network standard.

In step S101, the network standard includes: GSM, CDMA, TD-SCDMA, WCDMA, CDMA2000, TD-LTE, FDD-LTE. The terminal includes a smart phone and the like. In different environments, the network coverage of each network standard is different, so for the terminal, there is a network environment value under the environment, and the network environment value includes the network standard and the signal strength under the network standard. For example, in a certain environment, the terminal detects that the signal strength of the GSM network is -70dBm, the signal strength of the TD-SCDMA network is -60dBm, and the signal strength of the TD-LTE network is -70dBm.

S102. Search for the minimum call current corresponding to the detected network environment value in the pre-stored table of correspondence between network environment values and call current.

In step S102, in the terminal development stage, a table of correspondences between network environment values and call currents may be stored in the terminal, and data in the table of correspondences may be obtained through testing. For example, a corresponding relationship table between network environment value and call current is as follows:

The correspondence table includes the meaning that: when the terminal is talking on the GSM network standard and the signal is -50dBm, the calling current of the terminal is 80mA. Other data and so on.

The correspondence table is used to find the minimum call current corresponding to the detected network environment value. For example, as described in step S101, in a certain environment, the terminal detects that the signal strength of the GSM network is -70dBm, TD- The signal strength of the SCDMA network is -60dBm, and the signal strength of the TD-LTE network is -70dBm. From the table, it can be found that: when the signal strength of the GSM network is -70dBm, the call current is 115mA; the signal strength of the TD-SCDMA network is The call current at -60dBm is 62mA; the call current when the signal strength of the TD-LTE network is -70dBm is 163mA; obviously, the minimum call current of the terminal in this environment is 62mA, and its corresponding network standard is TD-SCDMA , switch the terminal to the TD-SCDMA network call, and the power consumption of the terminal is minimum.

In particular, if there are two or more groups of network environment values that correspond to the same minimum call current among the detected network environment values, the terminal can be preferentially switched to the network standard in the network environment values that contain stronger signal strength. Conversation, that is, according to the strength of the signal strength as the priority of the selection of the call; the priority of the network standard can also be defined in advance; the present invention does not limit this.

S103. Switch the terminal to the network standard call in the network environment value corresponding to the minimum call current.

In step S103, as described in step S102, the minimum call current of the terminal in a certain environment is found to be 62mA in the pre-stored table of correspondence between network environment values and call current, and the terminal is switched to TD-SCDMA corresponding to 62mA Internet calls, terminal power consumption is minimal.

In the terminal development stage, the present invention stores the correspondence table between the network environment value and the call current in the terminal, finds the network standard corresponding to the minimum call current according to the correspondence table, and directly switches the call network to the one corresponding to the minimum call current from the terminal side. The network standard achieves the purpose of reducing terminal power consumption and improving terminal battery life; and does not need to interact with the base station, switching is faster and saves resources.

The present invention pre-stores the corresponding relationship table between the network environment value and the call current in the terminal. When the terminal wants to make a call, it detects the network environment value of the terminal in the environment where the terminal is located, and finds out the corresponding network environment value in the corresponding relationship table. The minimum call current, and switch the terminal to the network standard call in the network environment value corresponding to the minimum call current, so as to achieve the purpose of reducing terminal power consumption and improving terminal battery life.

Embodiment two

Embodiment 2 provides two application scenarios of the present invention, and further explains the method of the present invention in combination with the application scenarios.

It is assumed that the terminal supports all network standards;

In the terminal development stage, the corresponding relationship between the tested network environment value and the call current is as follows:

Application Scenario 1

Set up a mobile 4G card on the terminal. The mobile 4G card supports three network standards: GSM, TD-SCDMA, and TD-LTE; -LTE signal strength is -90dBm, no TD-SCDMA signal is detected (because the coverage of mobile TD-SCDMA is very small, there is no signal in many places); look up the corresponding current of GSM signal -60dBm from the table is 95mA, TD-LTE signal The call current corresponding to -90dBm is 240mA, obviously 240mA>90mA, so switch the terminal to the GSM network corresponding to 95mA for calls.

Application Scenario 2

Set up a telecom 4G card on the terminal. The telecom 4G card supports TD-LTE, FDD-LTE, and CDMA2000 three network standards; if the user is going to make a call in the environment where the user is, it is detected that the signal strength of the TD-LTE received by the terminal is -80dBm , FDD-LTE signal strength is -75dBm, CDMA2000 signal strength is -85dBm, look up from the table, the call current corresponding to TD-LTE signal -80dBm is 195mA, the call current corresponding to FDD-LTE signal -75dBm is 205mA, CDMA2000 signal The call current corresponding to -85dBm is 347mA, obviously 195mA is the minimum, so switch the terminal to the TD-LTE network corresponding to 195mA for calls.

The method described in the present invention will be further described below in conjunction with the above application scenarios.

Referring to Figure 2, a call method under a hybrid network system, including:

S201. Set a SIM card on the terminal.

For example, a certain terminal supports GSM, TD-SCDMA, TD-LTE, FDD-LTE, and CDMA2000 network standards. The SIM card installed in the terminal only supports three network standards: GSM, TD-SCDMA, and TD-LTE. When the SIM card is built into the terminal, it can only detect the three networks of GSM, TD-SCDMA, and TD-LTE. format.

In step S202, steps S203 to S205 are performed only when the terminal has an incoming call or an outgoing call, and the switching of the power-saving network system is not usually performed.

Of course, a call setting item can also be added to the terminal, so that the user has the right to choose whether to switch to the power-saving network system during a call. Add a call setting item in the terminal. When the call setting item is not opened, the terminal calls with the default network standard of the SIM card; when the call setting item is opened, when an incoming or outgoing call is detected, the terminal switches to the provincial Telephone calls.

S203. Detect the network environment value of the terminal in the environment where the network environment value includes a network standard and a signal strength under the network standard.

S204. Search the minimum call current corresponding to the detected network environment value in the pre-stored table of correspondence between network environment values and call current.

S205. Switch the terminal to the network standard call in the network environment value corresponding to the minimum call current.

In the terminal development stage, the present invention stores the correspondence table between the network environment value and the call current in the terminal, finds the network standard corresponding to the minimum call current according to the correspondence table, and directly switches the call network to the one corresponding to the minimum call current from the terminal side. The network standard achieves the purpose of reducing terminal power consumption and improving terminal battery life; and does not need to interact with the base station, switching is faster and saves resources.

The present invention pre-stores the corresponding relationship table between the network environment value and the call current in the terminal. When the terminal wants to make a call, it detects the network environment value of the terminal in the environment where the terminal is located, and finds out the corresponding network environment value in the corresponding relationship table. The minimum call current, and switch the terminal to the network standard call in the network environment value corresponding to the minimum call current, so as to achieve the purpose of reducing terminal power consumption and improving terminal battery life.
