摘要： This application provides a call method and a terminal device. The method includes: when roaming from a home public land mobile network (HPLMN) to a visited public land mobile network (VPLMN), a terminal device obtains a first emergency number list of the VPLMN, and the emergency number corresponds to at least one emergency service type; the terminal device obtains a first number, and when the first number is an emergency number in a second emergency number list of the HPLMN and the first number is not an emergency number in the first emergency number list, determines a second number based on the first number, where the second number is the emergency number in the first emergency number list, and the second number and the first number correspond to a same emergency service type; and the terminal device initiates an emergency call based on the second number.

摘要： A communication method for a mobile terminal and a mobile terminal, where the communication method includes detecting whether the mobile terminal uses a call service, obtaining a state of an access control circuit when the mobile terminal uses the call service, and selecting a process of network quality monitoring based on the obtained state of the access control circuit, where the process of network quality monitoring includes stopping network quality monitoring, or stopping reporting a network quality monitoring result to a network side. Hence, the network side can process the call service of the mobile terminal based on the process of network quality monitoring performed by the mobile terminal to avoid a before-ringing inter-system handover and improve user experience.
