Embodiment Construction
[0036] In order to make the purpose, technical solution and advantages of the present application clearer, the implementation manners of the present application will be further described in detail below in conjunction with the accompanying drawings.
[0037] With the continuous improvement of people's living standards, mobile terminals have become an indispensable communication tool in people's daily life. A current mobile terminal generally includes an application processor and a baseband processor, and a call-related process and an operating system run on the application processor. Call service is interrupted when the target call-related process on the application processor exits abnormally. In related technologies, when the target call-related process exits abnormally, it will directly switch to the backup process to process the call service, so as to ensure that the call service is not interrupted. However, this master-backup process technology needs to prepare double the...

The present application provides a call service processing method and device, which belong to the technical field of communication. The method includes: when detecting that the first call-related process exits abnormally during the call, the mobile terminal restarts the first call-related process, and the media data channel for transmitting the media data stream is in a connected state. Then, after detecting that the process related to the first call is restarted successfully, the mobile terminal obtains the current call state of the mobile terminal. When the current call state of the mobile terminal is the connected state, the mobile terminal restores the call state of the first call-related process to the current call state, which solves the need to prepare double memory resources in order to avoid call service interruption, and the overhead is large. And the problem of the cumbersome backup process realizes that in order to avoid the interruption of the call service, there is no need to prepare double the memory resources, which reduces the overhead and simplifies the processing process of the call service, which is used to process the call service.
Description
technical field [0001] The present application relates to the technical field of communications, and in particular to a call service processing method and device. Background technique [0002] Current mobile terminals usually include an application processor (Application Processor, AP) and a baseband processor (Baseband Processor, BP). Call-related processes such as the interface process and the operating system. The mobile terminal can process the call service through the AP and BP, and provide the call service for the user. [0003] However, the target call-related process on the AP (taking the Android mobile terminal as an example, the target call-related process includes the system service process and the key system call application process) sometimes exits abnormally during operation. When the target call-related process exits abnormally, the target call-related process is restarted, and the restarted target call-related process will issue a control command for instru...
