Embodiment Construction

[0020] see figure 1 As shown, it is a schematic diagram of the composition framework of the communication system based on the AP of the Android system and the Modem for implementing the present invention, wherein the communication system of the AP and the Modem based on the Android system of the present invention relates to the application layer of the Android system, the Android framework layer, Java Language and C language conversion layer and Qualcomm AP and Modem communication layer.

[0021] The application layer of the Android system usually has applications such as "MMS application", "call application", "customer setting application" and "engineer application". To process related logic such as user interface display, the above-mentioned application program will call the interface implemented in the present invention.

[0022] The Android framework layer is a very important part of the Android system. It handles various functional logics of the platform and provides var...

Abstract

The invention discloses an AP and Modem communication system based on an Android system. The system comprises an interface transparent transmission module, an interface conversion module, a QMI (Qualcomm Modem Interface) message encapsulation module. The interface transparent transmission module is arranged in an Android frame layer, is used for realizing an interface transparent transmission function and transmits a function request of an application layer to a Java language and C language conversion layer. The interface conversion module transmits the request of the Android frame layer to a first AP and Modem communication layer. The QMI message encapsulation module analyzes a socket message body of the Java language and C language conversion layer, encapsulates a QMI message and sends the message to a Modem side. A QMI message analysis module is arranged in a second AP and Modem communication layer of the Modem side. The QMI message analysis module receives and analyzes the QMI message from an AP side, identifies a function demand according to a value of a customized message word, calls a bottom layer function interface of the Modem side to realize a function, encapsulates a performance result into the QMI message and returns the message to the AP.

Description

[0001] 【Technical field】 [0002] The invention relates to the technical field of communication, in particular to a communication system based on an Android system and an AP and a Modem. [0003] 【Background technique】 [0004] At present, most of the smart phones using the Android system in the market use the chipset of Qualcomm. In the specific design, two chips are usually used, one of which is responsible for the operation of the user interface and the Android operating system, usually called AP, and the other One is responsible for low-level functions such as radio frequency communication (voice calls, data services, network connections), and is usually called a Modem. [0005] In Android 4.0 and above, Qualcomm uses its self-developed QMI (Qualcomm Modem Interface Qualcomm RF module communication interface) technology to completely replace the previous RPC technology. At the same time, Qualcomm has also developed corresponding tools to generate QMI message sending and re...
