Method for processing network communication function abnormality, application processor and user terminal

Abstract

The invention discloses a method for processing a network communication function abnormality. The method includes the following steps: an application processor receives an abnormality indication message sent by a modem when a protocol stack state abnormality is detected; the application process closes a first protocol stack that causes the protocol stack state abnormality; the application processor enables a second protocol stack and uses the second protocol stack to perform network registration, wherein the second protocol stack is a protocol stack among a plurality of protocol stacks supported by the modem except the first protocol stack; and if the second protocol stack is successfully registered, the application processor records current position information. An embodiment of the invention also provides an application processor and a user terminal. By adoption of the method for processing the network communication function abnormality, the application process and the user terminal provided by the embodiment of the invention, the abnormality of a network communication function can be rapidly detected and restored.

Description

technical field [0001] The present invention relates to the field of communication technology, and in particular to a method for processing abnormal network communication functions, an application processor and a user terminal. Background technique [0002] With the rapid development of the mobile Internet, the proportion of data services is increasing, which makes the role and status of the modem in the smartphone become increasingly important. The modem is used to convert the data to be sent into radio frequency signals and convert radio frequency signals into Handle data, handle access stratum (AS) and non-access stratum (NAS) signaling, and interface with the AP processor, etc. During the use of smartphones, smartphones may switch between different communication systems (such as 2G, 3G and 4G communication systems), and abnormalities may often occur during the communication system switching process, and the mobile phone cannot be connected to the network normally Commun...
