This application provides a method for calibrating satellite short message communication charging. In the method, an electronic device sends a target satellite short message to a satellite, performs a pre-fee-deduction operation for a satellite short message service, and updates a first parameter to a first value, where the first parameter is a remaining quota that is of the satellite short message service and that is stored in the electronic device. When the electronic device is connected to a communication network, the electronic device sends the first value to a server. The electronic device receives a first calibration result sent by the server, where the first calibration result indicates whether the first value is consistent with a second value, and the second value is a value of a remaining quota that is stored in the server. The electronic device calibrates the first parameter based on the first calibration result.

A computer-implemented method for managing incoming calls comprises receiving, at an intermediate server communicatively coupled to a mobile phone associated with a first phone number corresponding to a first contact group and a second phone number corresponding to a second contact group, a request to receive an incoming call associated with a caller phone number. The intermediate server identifies a contact group associated with the request. The identified contact group comprises the first contact group in response to the received request corresponding to the first phone number, and the identified contact group comprises the second contact group in response to the received request corresponding to the second phone number. The intermediate server selects a notification based on the identified contact group. The intermediate server modifies the request to receive an incoming call to include the selected notification and routes the modified request to the mobile phone.
