Background

With the continuous development of communication technology, the communication technology is continuously updated, and mobile phones become necessities for users to live. Along with the continuous popularization of mobile phones, users have higher requirements on the comfort level and the convenience of using the mobile phones, and in order to continuously meet the requirements of the users, various mobile phone developers also continuously update various functions of the mobile phones so as to improve the comfort level and the convenience of the mobile phones. In the process of research and development of the mobile phone, a mobile phone research and development company needs to debug the researched and developed functions of the mobile phone so as to detect whether the functions of the mobile phone are normal or not.

In the prior art, because Application Processor (AP) system software is generally developed and debugged in advance independently of hardware devices or baseband system software, when a mobile phone developer debugged a developed mobile phone, the mobile phone developer generally provides a simulation function of a mobile phone display system for debugging through an AP system simulator, for example, after a mobile phone AP system is connected to an AP system simulator, the AP system simulator simulates an operating environment of an AP system application program, the AP system runs the application program in the AP system, and the AP system simulator detects whether a process of the AP system running the application program in the AP system is normal, and if so, the mobile phone is determined to be a qualified mobile phone.

However, the AP system in the mobile phone needs to perform service interaction with the baseband in addition to running the application program in the AP system, and the existing AP system simulator is limited to debugging the application program in the AP system, and cannot realize simulation of service interaction between the AP system and the baseband, which results in that it cannot be determined whether the AP system is working normally when the AP system performs service interaction with the baseband, so that a mobile phone developer needs to perform service interaction verification on the AP system and the baseband of the mobile phone on a specific hardware device or application platform, which will increase the development cycle of the mobile phone, thereby increasing the development cost.

Disclosure of Invention

The embodiment of the invention provides an AP system monitoring method, which aims to shorten the research and development period of a mobile terminal and further reduce the research and development cost of the mobile terminal.

The AP system monitoring method provided by the embodiment of the invention can comprise the following steps:

the baseband simulator establishes connection with the AP system;

the baseband simulator is in baseband communication with the AP system;

the baseband simulator monitors the baseband communication process of the baseband simulator and the AP system, judges whether the baseband communication process is abnormal or not, and executes processing operation corresponding to the abnormality if the baseband communication process is abnormal.

According to the technical scheme, the embodiment of the invention has the following advantages: the baseband simulator establishes connection with the AP system; the baseband simulator is in baseband communication with the AP system; the baseband simulator monitors the baseband communication process of the baseband simulator and the AP system, judges whether the baseband communication process is abnormal or not, and executes processing operation corresponding to the abnormality if the baseband communication process is abnormal. After the baseband simulator is connected with the AP system, the baseband simulator simulates baseband communication between the baseband and the AP system, and the baseband simulator monitors whether the baseband communication process is abnormal or not and carries out corresponding processing. Therefore, a mobile phone developer can determine whether the AP system works normally when the AP system and the baseband carry out service interaction without verifying the service interaction between the AP system and the baseband of the mobile phone on a specific hardware device or an application platform, thereby shortening the development cycle of the mobile terminal and further reducing the development cost of the mobile terminal.

In the research and development process of the AP system of the terminal, when a terminal research and development person needs to perform data interaction on the AP system and the baseband, whether the AP system works normally is detected. When a terminal developer needs to detect the AP system, the terminal developer starts the AP system, a baseband simulator uses an independent process or thread for starting and loading, and the baseband simulator creates N service threads; each service thread corresponds to the SIM card started by the AP system, and the baseband simulator establishes a socket service connection for each service thread as a transmission channel to establish connection with the AP system; the socket service connection at least comprises a socket client connecting channel, and each service thread and the socket service connection connected with the service thread have the same identification mark. For example, the baseband simulator creates a Modem service thread 1, a Modem service thread 2, a SIM card 1, a SIM card 2 corresponding to the mobile phone, and the baseband simulator creates a socket service connection a for the Modem service thread 1, the baseband simulator creates a socket service connection B for the Modem service thread 2, the Modem service thread 1 and the socket service connection a have the same identifier, such as the card number 13122332323 of the SIM card 1, the Modem service thread 2 and the socket service connection B have the same identifier, such as the card number 13222332323 of the SIM card 2, each socket service connection may include one socket client connection channel or a plurality of socket client connection channels, such as the socket service connection a, which may include the socket client connection channel a and the socket client connection channel B, the socket service connection B may include the socket client connection channel n and the socket client connection channel m, and the socket service connection a and the socket service connection B may only have one socket and a socket connection capability in the same time slot The system performs service interaction, the socket service connection a and the socket service connection B can also perform service interaction with the AP system simultaneously, the socket client connection channel a and the socket client connection channel B can respectively correspond to a baseband service, for example, the socket client connection channel a is a calling service of the SIM card 1, the socket client connection channel B is a called service of the SIM card 1, and the socket client connection channel n and the socket client connection channel m can also respectively correspond to a calling service of the SIM card 2 and a called service of the SIM card 2. After the baseband simulator is connected with the AP system through the socket service connection, the baseband simulator simulates a baseband to communicate with the AP system. For example, the baseband simulator receives a call service initiated by the AP system, and the baseband simulator simulates a baseband return call service response. The baseband simulator monitors the communication process of the call service to determine whether the communication process is abnormal, for example, the baseband simulator may determine whether data interaction between the AP system and the baseband simulator corresponds to data interaction during the communication process of the AP system and the baseband, the data may include a SIM card number during the communication process of the call service, or the baseband simulator may determine whether signaling interaction between the AP system and the baseband simulator corresponds to signaling interaction during the communication process of the AP system and the baseband, the signaling may include a call initiation instruction during the communication process of the call service, or the baseband simulator may determine whether a connection state between the AP system and the baseband simulator corresponds to a connection state during the communication process of the AP system and the baseband during the communication process of the call service, the connection state may be connection stable, or connection disconnected. If not, the baseband simulator can generate a corresponding abnormal log according to the abnormality or initiate an alarm prompt. If yes, the AP system can be determined to work normally. For example, if the connection state is disconnected and does not match the connection state in the communication process between the AP system and the baseband, the baseband simulator determines that the connection state is abnormal, generates an abnormal log of the disconnection, or initiates an alarm prompt.
