The present invention relates to the design technology of a new concept mobile phone using the SNMP protocol for module download and network management in an SDR system. In particular, the present invention can simultaneously accommodate system control and network management. The present invention relates to a mobile phone device using the SNP protocol in the SD system.

Conventional mobile phones (terminal software (S / W)) operate based on ROTS capable of real-time processing. That is, it controls all hardware (H / W) of the terminal and takes charge of various call processing. In other words, the terminal software is processed in a real-time processing RTOS by the corresponding function processing routines based on basic control tasks.

The task-specific roles that can be configured by default, although slightly different for each manufacturer, are the main control task, which is responsible for creating, executing, and destroying control tasks, while the watchdog task is responsible for monitoring all software. In this case, the IPIROM database task is responsible for nonvolatile memory management, the handset task is responsible for keyboard and call processing, and the diagnostic task is for external terminal control or data logging. The Transmit Task is responsible for transmitting related functions such as calling and channel searching, the Receiving task is responsible for generating incoming messages, and the search task is responsible for system acquisition functions such as pilot PN acquisition and timing conversion. The user interface task is in charge of the state processing function of the terminal.

In the case of the existing system, each task is embedded in the flash ROM, or the software in the DSP and FPGA cannot be reconfigured as an ASIC, but the SDR (SDR: Software Defined Radio) system is largely used to control the system. It is divided into the network management part, and it is configured to dynamically download tasks including the functions of the existing phone and to use various modules using the Internet.

However, in the SD system according to the prior art, it is difficult to reconfigure the system by downloading software modules and hardware modules, thereby making it difficult to build an optimal system environment.

Accordingly, an object of the present invention is to enable easy download and reconfiguration of software modules and hardware modules, as well as advantages of conventional phones, and SNMP (SNMP) for information collection and management of various modules from the Internet network other than the server. : Provides a mobile phone device using the SMP MP protocol in SD to build a system using the Smple Network Management Information (Smple Network Management Information) protocol.

The first feature of the present invention is that the module to be downloaded by using the advantage of CORBA (Object Download) to communicate with other objects in an object-oriented manner so that each other can only interface with the API.

A second feature of the present invention is to enable direct search of entry points within a symbol table in modules compiled in the system to perform downloaded object module (cross compile) tasks.

The third aspect of the present invention is to use the SNMP protocol, which is a standardized management protocol, to find the state of the module and the required module through the Internet when there is no module in the downloading server system.

The mobile phone device using the SNP protocol in the SD system according to the present invention may be configured to reconfigure a waveform application, maintain and preserve a change record of a domain profile, enable an interface of a domain manager using a download agent, and the like. And a domain manager that performs registration functions such as distributing or accessing software resources, deregistering devices, launching applications, and configuring a dynamic set of virtual paths between two sources in the radio. ; Provides a list of hardware devices, software resources that are shared with the resource manager, reports the capabilities needed for the hardware modules in the radio, performs boot and initialization functions, and provides a list of hardware resources controlled by the resource manager. The operation of the present invention configured as described above, configured as a resource manager for loading and executing suitable software, will be described in detail with reference to FIGS. 1 and 2.

When the file system required by the domain manager 11A is requested to the download agent 11B, the download agent 11B searches for the corresponding file systems on the Internet and presents the result, and among them, the domain manager 11A. Download the file system you select (eg P, MA, Modem, Data).

The resource manager (not shown in the figure) executes the file systems P, MA, Modem, and Data downloaded to the domain manager 11A, and the device manager 11C executes the file systems P, MA, Modem, and Data. And necessary files are downloaded to the DS 13 side.

To this end, the domain manager 11A performs a host and registration function as follows.

That is, the domain manager 11A includes a function of reconfiguring a waveform application, a function of maintaining and preserving a track record of a domain profile, and a download agent to perform a host function of the domain manager 11A. Perform the functions that make the interface possible.

In addition, the domain manager 11A uses other CF components and resource managers to distribute or access software resources to perform a registration function, and device registration, termination, and the like using the resource manager and domain manager 11A. It launches an application and configures a set of dynamic virtual paths between two sources in a radio.

In addition, the resource manager provides a property list of hardware devices and software resources that are shared with the resource manager, and reports the capabilities required for the hardware modules in the radio to ensure proper interoperability. In addition, it performs boot and initialization functions, and loads and executes the appropriate software for the given hardware controlled by the resource manager.

On the other hand, Figure 2 shows another embodiment of the present invention, a new optimal module as the agent intelligently browses in other networks other than the server to build and download the system management application 212 on the domain manager 211A layer It is implemented with SNMP, the network management standard, so that it can be downloaded.

In addition, a management information base (MIB) 221, 231 is provided for each node 220, 230 to store all the module information necessary for each node.

As described in detail above, the present invention makes it possible to easily download and reconfigure software modules and hardware modules necessary for an SDD system, and to use SNMP protocols for collecting and managing information on various modules from an Internet network other than a server. By building the system, there is an effect that can provide a more improved service.
