Description

Platform development verification system of mobile communication terminal {Platform developing appratus for mobile communication device}

The present invention relates to a platform development verification system for a mobile communication terminal, and more particularly, a platform of a mobile communication terminal that implements the same environment as an actual terminal and allows an application program or a mobile platform to be executed or executed from the mobile terminal to be developed or verified. It relates to a development verification system.

As the wireless Internet service becomes more complex and active, the platform for providing wireless Internet service is also getting more complex. Recently, as hardware such as cameras and MP3 players are added to portable terminals, unlike the PC environment, each hardware is used as it is being complexed. Many applications that run under the hood are also getting complicated.

1 is a diagram illustrating a platform development verification process of a mobile communication terminal according to the prior art.

The platform development verification process of the mobile terminal according to the prior art, as shown in Figure 1, can be largely divided into two stages, in the first stage is emulated (emulation) of the handset hardware on the PC to be implemented and implemented virtually The HAL (Handset Adaptation Layer) is implemented on the handset hardware so that the platform can be developed independently of the hardware. At this time, verify whether the HAL is properly implemented through the HTK.

Next, when the wireless Internet platform such as WIPI is developed in the second step, the port is ported onto the HAL, and then the ported platform is verified through the verification application. In this case, the WIPI is also verified to be implemented according to the standard specification. After verification, debugging is performed again by porting the developed platform to the actual terminal.

That is, in the case of the platform development verification process of the mobile communication terminal according to the prior art, the operating system environment such as a PC itself is not developed or verified in the terminal to be actually applied, but is developed or verified in an environment different from the terminal. Therefore, even if the application is developed in a stabilized emulator, many operating errors occur when it is applied to actual handset hardware.

In particular, the software applied to the mobile communication terminal generally has a slightly different UI or function depending on the request of the carrier to which the terminal is to be used. There is a problem that a considerable time and manpower is required for debugging and stabilization performed after porting.

The present invention is to solve the above-mentioned problems, in developing a platform or application for a mobile communication terminal, by implementing an environment similar to the actual terminal environment by the mobile communication that can improve the efficiency of the solution development task of the terminal We propose a platform development verification system for a terminal.

More specifically, in accordance with an embodiment of the present invention includes a platform emulator for developing and verifying the application or mobile platform of the mobile communication terminal, the platform emulator is a modem chip for the CPU core and call processing of the mobile communication terminal A virtual hardware layer that virtually implements the same hardware architecture as the handset hardware, including the handset hardware; An operating system layer mounted on the virtual hardware layer to perform an operating system function of the mobile communication terminal; And an application layer in which the application or the mobile platform of the verification target or the development target is mounted and executed on the operating system layer to implement the same environment as the actual terminal, and based on the operating system for the terminal, By developing, the debugging work can be minimized when porting to the actual terminal.

Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings.

FIG. 2 is a diagram illustrating a structure of a platform emulator in a platform development verification system for a mobile communication terminal according to the prior art and the embodiment of the present invention. FIG. Figure 2 (b) is a diagram showing the hierarchical structure implemented in the actual terminal, Figure 2 (c) is a diagram showing the structure of a platform emulator according to an embodiment of the present invention.

In the platform development verification system of a mobile communication terminal according to an embodiment of the present invention, the platform emulator may be configured as shown in Figure 2 (c), which is the actual as shown in Figure 2 (b) It has a structure almost similar to the operating environment of the terminal.

That is, a mobile communication terminal which is actually commercialized, as shown in FIG. 2 (b), includes hardware such as an LCD and a keypad, and a device driver that supports the hardware to operate normally. The operating system layer, HAL, and platform / browser layer are implemented in this order.

The platform emulator according to an embodiment of the present invention develops and emulates a related application or a wireless Internet platform to perform various functions or services available through a mobile communication terminal.

Emulation can generally be realized by mimicking different kinds of hardware or software, minimizing the impact of switching from one computer system to another and allowing existing programs to continue to be used.

Therefore, the platform emulator according to an embodiment of the present invention enables a similar operation to a real terminal even in a development verification system having an operation structure different from that of a real terminal such as a PC or a workstation. When it is mounted on the actual terminal handset, it is possible to minimize the modification or debugging (debugging) to shorten the development and verification period, thereby greatly reducing the time required to commercialize the actual developed terminal. In addition, in developing various terminal-related solutions, by providing an environment similar to the actual terminal, the efficiency of development work can be greatly improved.

Therefore, the platform emulator according to an embodiment of the present invention as described above, as shown in Figure 2 (c), a hardware architecture for performing the CPU core and call processing of the terminal supporting the wireless Internet environment (architecture) Virtual hardware including an modem chip processor, and the like, an operating system layer, and an application layer for executing an application on a platform.

The virtual hardware simulates the same hardware architecture as the handset hardware that makes up the actual terminal.It is a modem chip processor that enables wireless communication such as CDMA, memory for storing data, and reading or displaying data on the screen. Image processor, LCD with image output to support user graphic interface, keypad composed of number keys and direction keys and function keys, real terminal such as ear-jack, microphone and speaker to listen to sound by plugging in earphone Handset hardware constituting the can be implemented as it is. In addition, each hardware device may be implemented as it is by selecting a manufacturer or a product as a product to be applied to an actual terminal.

In addition, a device driver for each device may be mounted so that virtually implemented hardware can operate almost similarly to an actual terminal.

The operating system layer is a layer on which an operating system running in a mobile communication terminal is mounted, which is a base for executing various application software and communication protocols, and includes basic task management functions and inter-task communication functions.

Such an operating system, for example, refers to an operating system such as a Real-time-Executive (REX) OS or a Pioneer Server OS (pSOS) applied to a terminal that supports multitasking using a Qualcomm modem chip. In the present specification, an example of applying REX of Qualcomm as an OS to be applied to the OS layer is not limited thereto. In addition to the above-mentioned pSOS, all OSs applicable to mobile communication terminals such as Windows CE, Symbian, and embedded Linux are all applicable. Can be applied.

Therefore, the platform development verification system according to an embodiment of the present invention is a memory for storing a variety of hardware information applied to the actual terminal, a program for virtually simulating each hardware according to the specification, and the source code of the terminal operating system REX If the virtual simulation of the hardware can be automatically or manually loading the source code of the REX to allow the REX to be performed.

That is, the platform development verification system according to an embodiment of the present invention allows a REX OS to be executed under a windows or linux-based operating system executed on a computer such as a PC or a workstation, and is the same as the REX of a terminal that is commercially available. By providing all the functions (functions) provided under the same name on windows or linux, they can be run on a computer without any special changes to the basic program applied to the terminal, and the programs run or developed accordingly can be applied to the actual terminal. Alternatively, the tester may enable all operations performed on the actual terminal.

Therefore, it is possible to reduce the time and resources required to develop and verify a mobile platform or application, thereby enhancing the competitiveness in the terminal software development field.

For example, in more detail, the REX OS performed through the platform emulator according to an embodiment of the present invention includes all task tasks including a TCB (Task Control Block) having the same structure as the terminal. It can be created and executed as a task of the same level as a task on REX executed in. In addition, it can support all 30 tasks implemented through the actual operating environment of the terminal, manage the task status, process the transmission and reception of signals and messages transmitted and received between each task, task and interrupt processing using timers, task priority By implementing functions such as management and scheduling (scheduling), so that the REX OS can be driven almost the same as the actual terminal. In addition, the system timer is used to generate ticks at the same interval as that of the phone, so that the operation is performed in the same manner as the mobile terminal.

On top of the REX OS are ported the Dual Mode Subscriber Software (DMSS) and the UI platform. DMSS is a set of core software for mobile communication terminal installed on OS such as REX. It includes communication protocol, various middleware, and application software. Source code for implementing DMSS is also stored in the memory to execute REX. Can be run together.

The application layer may include a handset application layer or a protocol adaptation layer (PAL) and a mobile platform.

The Handset Adaptation Layer (HAL) is an abstraction layer for maintaining hardware independence of the platform. It supports upper layers to operate independently of the native system on the handset application layer, and the protocol application layer is also a handset application layer. Similarly, the platform supports independence so that it is independent of the protocol layer.

In the prior art, only the handset application layer is configured to operate as a window emulator by porting to the window environment, but in the embodiment according to the present invention, the platform for a terminal can be implemented as it is by porting the handset application layer on the REX.

In addition, since HAL is applied in a state where hardware, a device driver, and an operating system are all implemented similarly to an operating environment in an actual terminal, the HAL implementation source used in the platform emulator according to an embodiment of the present invention is applied. It can be applied to the actual terminal as it is, unlike the conventional operation is not required to verify and correct the operation normally in the terminal.

In the platform development verification system according to an embodiment of the present invention, the platform emulator may provide a user interface for the terminal software developer to perform development through the platform emulator. And through this, a mobile platform such as WIPI, Brew, or KUN, etc. to support the wireless Internet service can be developed to be implemented as a higher layer of the handset application layer.

There are two methods of supporting the wireless Internet service, a browser method used to use the Internet by wire, and a mobile platform method that downloads and uses an application program.

The mobile platform method can be divided into virtual machine (VM) technology and native binary technology. VM technology is a software CPU (that is, virtual Machine) into intermediate code that can be operated on, and the virtual machine translates the intermediate code into machine language for the CPU core of the actual terminal and executes it.

Another technology, native binary technology, is generally similar to the method of writing, compiling, and executing a program, which executes the developed program by making it a machine language running on the CPU on which the program is executed.

The VM-based wireless internet platform has a burden of interpreting intermediate code using a software CPU during execution, which makes the user feel relatively slow at a relatively low speed in a mobile terminal with limited CPU performance and resources. do. However, VM technology has the advantage of relatively stable system and complete security. In particular, brew, a wireless Internet platform proposed by Cullcom, is embedded in Qualcomm's modem chip and can be directly connected to the hardware of the terminal, so the processing speed is very high, and even Java VM can be run smoothly on the Brew platform. Applications available include Bluetooth, MPEG4, MIDI, MP3, voice recognition, color LCD, USB, SD RAM card, MMC card and gpsOne.

On the other hand, by developing a basic application that can be performed directly by using the handset hardware, such as phone book management, short text transmission and reception, call origination / reception, camera shooting, such as to implement the upper layer of the handset application layer or parallel deployment Can be.

In addition, various types of applications based on the developed mobile platform or browser can be developed and implemented.

Platform development verification system according to an embodiment of the present invention can verify whether the developed mobile platform, browser, applications, etc. are operating normally.

That is, the platform emulator according to an embodiment of the present invention can verify whether the input / output of a signal is normally performed with respect to a previously developed mobile platform or application, and the mobile terminal or application developed in connection with an actual mobile communication terminal can be verified. You can apply it directly to your handset hardware and then perform debugging.

3 is a diagram illustrating an example displayed on an actual screen by executing a platform emulator in a platform development verification system of a mobile communication terminal according to an embodiment of the present invention.

In the platform development verification system of a mobile communication terminal according to an embodiment of the present invention, when the platform emulator is executed, the REX OS starts to operate, and the REX OS generates and operates a TMC task which is a main task. In addition, the TMC task generates a HS (HandSet) task, an FS task, a nonvolatile memory (NV) task, a call manager (CM) task, a user interface (UI) task, and the like, in a standby state. When the creation of all the tasks is completed, the standby task is switched to the run state, and an emulator skin as shown in FIG. 3 is output on the computer screen. The emulator skin is implemented on one side A with the same appearance as the actual terminal to implement a user interface such that the user operates the actual terminal. On the other side (B), check whether the additional functions of the terminal such as telephone transmission / reception, short message transmission / reception, monitoring of internal memory contents, JAVA, BREW, WAP, sound, camera, etc. are normally performed or whether the developed software is normally executed. You can implement interfaces such as multiple tabs, text input fields, and buttons that let you do so.
