Embodiments of the invention

The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that, in the case of no conflict, the features in the embodiments and the embodiments of the present invention may be combined with each other arbitrarily.

Example 1

The mobile phone in the pocket or backpack may cause some misoperations due to friction between other sensors on the phone itself or other objects, such as unlocking the phone or answering the phone. In response to this problem, the inventor thought that when the terminal receives any operation instruction, if it can be judged that the user holds the mobile phone to send the operation instruction at this time, it can be confirmed that the operation instruction is a valid instruction, according to the operation instruction. The corresponding processing can be performed, and if not, it is considered to be a misoperation. Wherein, at least the amount of change in the quality of the network signal before and after receiving the operation command can be used to determine whether the person holds the mobile phone.

Based on this, the embodiment provides a method for preventing erroneous operation of the terminal. As shown in FIG. 1 , the method mainly includes the following operations:

Step 1: When receiving the operation instruction initiated by the user, the terminal determines the amount of change of the network signal quality before and after the terminal receives the operation instruction;

Step 2: If the amount of change in the network signal quality satisfies the first setting condition, the terminal determines that the received operation instruction is a valid instruction;

In step 3, the terminal performs corresponding processing according to the operation instruction.

In this embodiment, the operation instructions involved include an unlocking instruction, answering an incoming call instruction, or rejecting an incoming call instruction.

In the alternative, when the operation command received by the terminal is an answering call command, in addition to considering the amount of change in the quality of the network signal, it is also necessary to consider the amount of change in the transmit power before and after the terminal receives the operation command. This is because the basic architecture of the mobile phone includes the software system, baseband module, RF module, module, antenna layout, power supply, and peripheral circuits. The performance of the antenna is affected by human body induction. When the person holds the hand, the performance of the antenna is full. Both the radiation sensitivity (TIS) and the omnidirectional radiation power (TRP) values change. The TRP can be converted into a power value by an algorithm based on the radio frequency dynamic parameter (NV) of the mobile phone, and the TIS is characterized by a change in the strength of the signal (ie, network signal quality), and the network signal quality can be read by a modem command (AT Commands). The GSM is characterized by a received signal level (RxLev, Received Signal Level), WCDMA is characterized by Received Signal Code Power (RSCP), and LTE is characterized by Reference Signal Receiving Power (RSRP). That is to say, when the amount of change of the network signal quality and the amount of change of the transmission power respectively satisfy the corresponding setting conditions, it can be determined that the operation instruction received by the terminal is an effective instruction, that is, the variation of the network signal quality satisfies the first When the condition is set and the amount of change in the transmit power satisfies the second set condition, it is determined that the operation command received by the terminal is a valid command. The difference between the network signal quality parameter of the terminal at the time of the incoming call and the network signal quality parameter at the time of answering the incoming call or rejecting the incoming call is greater than or equal to the first set threshold (ie, the first setting is considered to be satisfied) Condition), the difference between the transmission power of the terminal at the time of the incoming call and the transmission power at the time of answering the incoming call or rejecting the incoming call is not less than or equal to the second set threshold (ie, the second set condition is considered to be satisfied).

When the difference between the transmission power and the transmission power at the time of answering the incoming call or rejecting the incoming call is not less than the second set threshold, it can be judged that the received operation command is a valid command.

In addition, the determining module 12 is further configured to: if it is determined that the network signal quality parameter and the transmitting power of the terminal at the time of incoming call and the network signal quality parameter and the transmitting power at the time of answering the incoming call or rejecting the incoming call, If any one does not satisfy the corresponding setting condition, it is determined that the received answering instruction is an invalid instruction.
