Embodiment 2

[0042] Example 2 and see attached figure 2 , It is a physical interface of the system about the communication between the network protocol stack and the mobile terminal. This system includes the mobile terminal interactively connected with the application layer and the network terminal interactively connected with the network. The mobile terminal and the network have mutually associated AT commands, responses, and information feedback links; the dynamic process is that the mobile terminal sends AT commands to the network, the network responds according to the protocol, and then sends the corresponding Information to the mobile terminal.

Embodiment 3

[0043] Example 3 and see attached image 3 , It is a generation interface of the telephone system under the Linux-based MID platform. The interface includes a dbus automatic generation tool module, a network module, a telephone module, a short message module, a device module, a display module, and a Sim card module. The dbus automatic generation tool module is respectively interactively connected with the network module, telephone module, short message module, equipment module, display module, and Sim card module. Among them, the dbus automatic generation tool module is a tool that can make dbus achieve more concise and clear results. As long as the xml file is modified, the corresponding network module, telephone module, SMS module, device module, display module, and Sim card module can be generated. And fully prepared for expansion.

Embodiment 4

[0044] Example 4 and see attached Figure 4 , It is a method for generating the telephone background service program of the telephone system under the Linux-based MI D platform. Due to the characteristics of the physical interface of the telephone system set by the present invention and the friendly interactive interface of the system, it is generating and scheduling the system There are the following steps when calling the background service program:

[0045] The first step, initialization: first initialize the modem protocol implementation module by the phone background service program module in the background program service unit, that is, the phone-server initializes the modem first, and sets the status of the modem according to the configuration file, such as s im card status, short message storage location, etc.;

[0046] The second step is to set the dbus to prevent multiple requests from accessing the modem protocol implementation module at the same time; that is to say, th...

Abstract

The invention relates to a Linux-based telephone system under a MID platform and an implementation method thereof. The telephone system has a simple overall structure, effectively prevents redundancy of the conventional telephone systems, is excellently compatible with networks of various systems, solves the separation of a protocol layer and an interface layer through a telephone service programmodule and records different atril dynamic link libraries according to different network systems; and the reliability of the program is ensured by adopting multithread and a thread lock in the processing of a message queue. Particularly, an RIL layer is adopted for a background program service unit, so that the interface extension of the telephone system in the future can be realized conveniently; full separation of a user interface (UI) and a server is realized; the customizing of the UI can be performed; minimal design of a database is adopted in storage; and an overall sound design architecture of the system is provided.

Description

Technical field [0001] The invention relates to a smart phone system applied to a Linux mobile platform, in particular to a method for implementing a telephone system under a Linux-based MID platform. Background technique [0002] Embedded system that has attracted much attention in the application field of today's smart phones. It is also a trend of Linux to embed phones on mobile systems, among which the representative ones are LIMO, LIPS and OpenMoko: [0003] LiMo is short for Linux+Mobile. This is an industry alliance. The sponsoring members of LiMo are: Motorola in the United States, NEC in Japan, NTT DoCoMo in Japan, Panasonic Mobile Communications in Japan, Samsung Electronics in South Korea, and Vodafone in the UK. [0004] LiPS stands for Linux Phone Standards Forum. LiPS Forum is an industry alliance led by France Telecom and currently has 33 members. The goal of LiPS Forum is also to standardize the development of Linux mobile phone software, and its idea is to formu...
