Number calling method and device, communication equipment and storage medium

Abstract

The invention relates to a number calling method and device, communication equipment and a storage medium. The method comprises the following steps: when a call request carrying an emergency number is received in a flight mode, acquiring a network type supported by a subscriber identity module card specified by the call request; determining a calling condition for calling an emergency number according to the network type supported by the specified user identification card; detecting whether a call condition for dialing the call emergency number is satisfied; and when a calling condition of calling the emergency number is satisfied, calling the emergency number based on the specified user identification card. By adopting the method, the call can be accurately judged to be carried out when the call requirement is met, unsuccessful call is avoided, and the success rate of calling the emergency number in the flight mode is effectively improved.

Description

technical field [0001] The present application relates to the technical field of communication, in particular to a number calling method, device, communication equipment and storage medium. Background technique [0002] With the development of communication technology, when the user encounters an emergency, he can use any available network of the communication device to call the emergency number to call the police or ask for help. For emergency numbers at home and abroad, in various situations, it is necessary to call the emergency number to a manual Taiwan, including setting the current mobile phone to flight mode (the Qualcomm baseband chip is turned off). [0003] For emergency numbers, if the mobile phone is inserted with a SIM (Subscriber Identity Module) card (the IC card held by a mobile user of the GSM system, called a subscriber identification card), it is divided into a service state and a non-service state, and the non-service state ( When the SIM card is inserte...

Problems solved by technology

[0004] like figure 1 As shown, the current plan for calling emergency numbers in flight mode is: first turn off the flight mode, wait for the Qualcomm baseband chip to be enabled, and the calling module monitors that the Qualcomm baseband chip is enabled, and initiates a call, but at this time there is no guarantee that the phone has been successful The resident network may still be in a no-service state, and the no-service state will change from LTE (Long Term Evolution, long-term evolution) / WCDMA (Wideband Code Division Multiple Access, wideband code division multiple access) / GSM (Global System For Mobile Communications, global mobile communication system) / CDMA (CodeDivision Multiple Access, spread spectrum multiple access digital communication technology) to try to make a call, the emergency number in China can only be successfully called from CDMA, in the case of LTE / WCDMA / GSM, it cannot be connected or It can only be connected to the automatic answering station, which will cause emergency calls to fail; some operators in other countries (such as Indian operator JIO) only support LTE network or LTE+NR (a global 5G standard based on OFDM's new air interface design) Network, calls must be made through VOLTE (Voiceover Long-Term Evolution, long-term evolution voice bearer) or VOWIFI (Voice over Wifi, the function of calling a phone through a wifi wireless network can be successful), if dialed from other methods, it will fail with a high probability

[0005] Therefore, the current method of calling emergency numbers in flight mode has a low success rate
