The present invention relates to a method of initializing and replacing a software component in an SCA-based base station system supporting dual mode, and an application package structure therefor. More specifically, in a dual mode base station based on the Software Communication Architecture (SCA), the software of the base station is componentized and deployed in the system, and the components are replaced and operated. The present invention relates to a method of initializing and replacing a software component to facilitate the operation, and an application package structure therefor.

Mobile communication systems have evolved from analog systems to digital systems through the rapid development of the semiconductor field through the 1970s and 1980s. Recent advances in high-speed analog-to-digital converters (ADCs) and digital-to-analog converters (DACs) with sampling rates close to 100 megaspread per second (Msps) The implementation of direct digital conversion between intermediate frequency and baseband signals is now possible. In addition, software signal reconfigurable baseband is increasingly available, as digital signal processing devices such as Digital Signal Processors (DSPs) and Field Programmable Gated Arrays (FPGAs) are becoming increasingly high-performance. The implementation of modems and improved signal processing modules has become possible. These technological advances enable the actual implementation of the SDR (Software Defined Radio) modem, which was proposed only conceptually.

Currently, the world's mobile telecommunications environment is dominated by a variety of multimode second-generation digital systems such as GSM in Europe, D-AMPS in North America, PDC in Japan, PHS in Korea, and IS-95 CDMA in our country. In addition, the 3rd generation broadband IMT-2000 standard, which has pursued a single standardization for the global roaming service, is also largely divided into 3GPP2 cdma2000 in North America and 3GPP W-CDMA system in Europe and Japan, which are widely commercialized locally. As a result, local second and third generation mobile communication standards require separate independent transmission and reception systems due to different air interfaces and incompatible access protocols, and it is true that roaming between these systems is very difficult. Therefore, in the situation where many mobile communication systems having various quality requirements and functions are mixed, the importance of the SDR technology that can accommodate various radio access standards through the conversion of modular software without modification of hardware becomes more important. have.

Meanwhile, SCA (Software Communication) is a standardized communication software structure designed to greatly improve interoperability between communication systems and reduce development and deployment costs in the Joint Tactical Radio System (JTRS) and Joint Program Office (JPO). Architecture). SCA adopts the common object request broker architecture (CORBA), which is an industry standard for real-time operating system (OS) and distributed object model, as a middleware to provide an integrated environment of heterogeneous hardware and software. This is an independent system design framework, not a specification specific to a particular system. SCA-based system refers to a communication system based on this SCA structure.

By way of example, the aforementioned SDR system adopts SCA as a standard for software frameworks. In SCA, an application is a class that installs, deploys, and executes several components that perform the function of one waveform in one package. How you configure this application can affect how the software works.

At present, a small number of systems applying SCA-based software frameworks are released, but there are many problems in operation, and their functions are inadequate. In addition, the SCA standard does not provide software component technology, does not provide a mechanism for storing or managing component files that can be deployed and replaced, and does not provide a mode switching method through software, making development and operation difficult. to be.

Accordingly, the existing SCA standard uses a method of configuring software components to be deployed in one application package and deploying, driving, and controlling the package in units. During operation using such an application package, if an application package needs to be replaced due to an update of one component, etc., it is inconvenient to relocate and run the application package including the new component after terminating the entire application. This exists. Accordingly, there is a problem in that the SCA method of terminating the entire application for replacing the application package is difficult to apply in the base station, which should always be operated for the mobile communication service.

In order to solve such a problem, Korean Patent Application No. 10-2001-0035032 "Resource Adapter in ED-Dial System" (2001.6.20) and Korean Patent Application No. 10-1997-0065537 "Mobile communication terminal device and its software platform" ( 1997.12.03), it provides mobile communication terminal and software platform that can download software platform for mobile video phone by using resource adapter and network application virtual machine that can transfer messages between independent resources. There is still no problem for use in the base station because it does not provide a method for configuring the respective application package to replace them alone.

In addition, through the "SCA Software Framework for the SDR Mobile Platform" published in the October 2003 telecommunication trend analysis, the basic structure and functions of the SCA software framework were developed using the Core Framework and the Non-Core Framework ( Non-Core Framework) is analyzed and provided, but it is also difficult to apply in the base station because it does not provide a method to replace the software components by configuring each application package alone.

In order to solve such a problem, the present invention is to configure the software of the base station in the SDR-based dual-mode base station based on the SCA in the SCA-based system, and to deploy and operate in the system, a component that requires replacement during operation If present, the present invention provides a method for initializing and replacing a software component in an SCA-based base station system supporting dual mode in which only a corresponding component can be replaced, and an application package structure therefor.

In order to achieve the technical problem, the present invention, as a software component initialization method of the SCA-based base station, in the method for initializing the software components required for the operation of the SCA (base station) system supporting a dual mode, (a Receiving and driving a CORBA (Common Object Request Broker Architecture) and a reconfiguration core framework for communication and reconfiguration management of software components from a base station manager that stores software components necessary for operating a base station system; (b) one or more application packages containing software components from the base station management unit, wherein the application packages consist of one software component for control and management of the base station system and one assembly controller component for controlling the software component.

The base station manager 170 is connected to the base station interconnection subsystem 150 to perform overall management of the base station such as overall operation maintenance of the base station, reconfiguration of the system, and user interface management.

2A and 2B are block diagrams illustrating a software structure and a package structure of a base station application in an SCA-based dual mode base station system.

In the SCA-based dual mode base station system to which the present invention is applied, the base station control block 156 is shown in FIG. The base station control block 156 in an SCA-based system basically includes a real-time operation system (RTOS) 210 and a CORBA middleware 220 defined in the SCA standard.

Real-time operating system 210 is located in every block within each subsystem, but CORBA middleware 220 is only present in base station control block 156 in base station interconnection subsystem 150. The SCA-based core framework consists of several components such as execution device 232, library 234, domain manager 236, device manager 238, and log service 240, and system reconfiguration. A reconfiguration core framework (RCF) 230 is provided above CORBA that supports.

The Radio Manager 250, which is an operator interface associated with the domain manager 216 of the reconfiguration core framework 230 and which is responsible for downloading, deploying, and running application packages in the system, provides a number of base station software components. After configuring as one package (hereinafter referred to as an 'application package'), it is placed in the execution device 232 through the domain manager 216, and the deployed base station application package is driven.

At this time, the structure of the application package disposed in the execution device 232 is as shown in Figure 2b.

The base station application mounted on the execution device 232 includes a modem component 262 for performing modem management functions, a MAC component 264 for generating a message for control and decryption, and a mode control for controlling a mode of a base station.

When a base station application package configured as shown in FIG. 2B is deployed and executed in a system, a naming tree registered in a naming server of the base station system is configured as shown in FIG. 4.

Since the base station application according to FIG. 2B consists of only one application package, an AssemblyControl and other components are registered under one ApplicationName.

In the first column of FIG. 4, the naming tree syntax for registering the assembly controller component 260 is located, and after the second column, the naming tree syntax for registering the software of the application package is located. Here, the length of the naming tree is determined according to the number of software components in the application package. Here, except for the assembly controller component 260, a naming tree of an application package having N software components is shown.

5 illustrates a naming tree registered in a naming server when an application package is executed according to an embodiment of the present invention.

When the application is executed in the dual mode base station system having the base station application package structure according to FIG. 3, the naming tree registered in the naming server is configured as shown in FIG. 5.

If there are N application packages in the base station application, the naming tree will have '2 × N' columns. In the naming tree illustrated in FIG. 5, the first column and the second column are naming tree syntax according to the execution of the first application, and the third column and the fourth column become naming tree syntax according to the execution of the second application.

In the first column of the naming tree syntax (ie, the first column, the third column, the fifth column, etc.) according to the execution of each application, the naming tree syntax for the assembly controller component included in each application is located. Done.

Here, when communication is possible between components belonging to another application, an object reference of the corresponding component may be obtained from the naming server using a predefined application name (ApplicationName). That is, when one component is executed, the corresponding component may be executed by using an assembly controller component belonging to another application.

6 is a flowchart illustrating a method of initializing a software component in an SCA-based base station system supporting dual mode according to an embodiment of the present invention.

In the SCA-based dual mode base station system, an application package including a software component to be used for base station operation is configured for each software component through the base station manager 170 (S602).

When the application package is configured, after the base station system initializes, the CORBA and reconfiguration core framework (RCF) is downloaded to the base station control block 156 for inter-component communication and reconfiguration management (S604) and then driven (S606). ).

The base station control block 156 downloads and stores the application package configured by the base station manager 170 for each software component. At this time, the configuration-related XML file is also downloaded (S608).

The base station control block 156 checks whether the common library file exists in the downloaded application package, and if the common library file exists (S610), downloads the common library component (S612).

Similarly, the base station control block 156 checks whether the device related component file exists in the downloaded application package, and if the device related component file exists (S614), the device related component file is downloaded to the corresponding processor directory (S616). ).

Then, the downloaded common library component is driven (S618), and the device related XML file is analyzed and driven to drive necessary device related components (S620).

Once a device related component is driven, the software component, which is an application to be operated on the device, is decompressed to the corresponding directory (S622), and the components to be loaded or executed are placed at the corresponding location. Then, the configuration related XML file is analyzed and processed to drive the component (S624). Then, base station software components required for base station operation are driven (S626).

When all component files are successfully driven, the initialization of the base station is completed by updating the state table or configuration table necessary for operating the base station, and the mobile communication service is provided to the mobile communication terminal 110 using the installed base station software component (S628). .

In this manner, software component initialization in an SCA-based base station system supporting dual mode is possible.

7 is a flowchart illustrating a method of replacing a software component in an SCA-based base station system supporting dual mode according to an embodiment of the present invention.

While providing the mobile communication service to the mobile communication terminal 110 using the software component installed in the base station (S702), if there is a replacement request command for a specific software component from the base station operator (S704), the specific base station software component requested to be replaced Stops and terminates in a safe manner (S706).

When execution of a specific component is stopped and terminated, an application package and configuration related XML file to be newly replaced are downloaded through the base station control block 156 (S708).

When the download of the application package is completed, after decompressing the application package in the directory (S710), parses the configuration-related XML file, and drives the software component of the base station to be replaced (S712).

If the application package is successfully replaced by the method as described above, the initialization with other related components is established and the provision of the mobile communication service through the base station is resumed (S714).

Through this method, a service can be provided by replacing a software component in an SCA-based base station system supporting dual mode.

The embodiments of the present invention described above are not implemented only through the apparatus and the method, but may be implemented through a program for realizing a function corresponding to the configuration of the embodiment of the present invention or a recording medium on which the program is recorded. Implementation may be easily implemented by those skilled in the art from the description of the above-described embodiments.

Although the embodiments of the present invention have been described in detail above, the scope of the present invention is not limited thereto, and various modifications and improvements of those skilled in the art using the basic concepts of the present invention defined in the following claims are also provided. It belongs to the scope of rights.
