Abstract

A mode inquiry and change method in a base station system for supporting multiple modes is provided to be capable of confirming the currently set operational mode to notify components which operate in multiple modes of the confirmed operational mode, so that the components can properly cope with the current operational mode. An operational mode change request signal which includes information on a node for changing an operational mode is received(S510,S520). It is confirmed whether the operational mode of the node is changeable, by using the operational mode change request signal(S530). If so, the operational mode set on the node is changed according to the operational mode change request signal(S540,S550). Node information which includes information on the changed operational mode is generated, and an application component required for the changed operational mode is loaded on the node(S560,S570).

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.

It only provides a component framework composed of the above, the contents can not be found for the inquiry and replacement method of the operation mode to be provided through the present invention.

In order to solve such a problem, the present invention is to check the current operating mode is set in the SCA-based base station system that supports multiple modes to inform the components operating in the multi-mode, the components are suitable for the current operation mode The present invention provides a method of mode inquiry and change in a base station system that supports multiple modes to operate correspondingly and to efficiently perform an operation mode replacement.

Generate an operation mode inquiry request signal of a node that wants to check.

Here, the multi-mode operating component 210, the multi-mode loading component 220, and the multi-mode communication adapter component 240, 242 may request the operation mode inquiry of the control node 130 or the call processing nodes 152, 156. have. At this time, when the multi-mode operation component 210, the multi-mode loading component 220 and the multi-mode communication adapter component (240, 242) requests the operation mode inquiry of a specific node, this operation mode inquiry request is a multi-mode control After being passed to the control node / call processing node operation mode inquiry module 232 of the manager component 230, the control node / call processing node operation mode inquiry module 232 may generate an operation mode inquiry request signal. The mode operation component 210, the multi mode loading component 220, and the multi mode communication adapter components 240 and 242 may generate a direct operation mode inquiry request signal (S410).

The operation mode inquiry request signal generated by the control node / call processing node operation mode inquiry module 232 or the multi-mode operation component 210, the multi-mode loading component 220, and the multi-mode communication adapter component 240, 242 is data. The data is transmitted to the data management module 260 through the management adapter component 250 (S420).

The data management module 260 confirms a node to be inquired through the operation mode inquiry request signal (S430), confirms the control node operation mode identifier 312 of the control node management module 310, or the call processing node management module. The operation mode information set in the requested node is confirmed by checking the call processing node operation mode identifiers 322 and 332 of 320 and 330 (S440).

5 is a flowchart illustrating a method of changing an operation mode of a multi-mode supporting base station system according to an embodiment of the present invention.

The control node / call processing node operation mode change module 234 of the multi-mode control manager component 230 is requested to change the operation mode set in the specific node. The control node / call processing node operation mode change module 234 that is requested to change the operation mode generates an operation mode change request signal including information on a specific node requested to change the operation mode (S510). The change request signal is transmitted to the multi-mode operation component 210 (S520).

The multi-mode operation component 210 analyzes whether the node is normal to check whether the operation mode of the node can be changed, and when it is confirmed that the operation mode can be changed (S530), the operation mode information currently set on the node is checked. Then, the node that wants to change the operation mode is notified of the change of the operation mode, and the resource set in the corresponding node is released (S540).

Then, the operation mode change request signal including the information on the specific node requested to change is transmitted to the data management module 260. The data management module 260 changes the operation mode set in the requested node according to the received operation mode change request signal (S550).

The data management module 260 then transmits node information including the information on the changed operation mode to the multi-mode loading component 220 (S560).

The multi-mode loading component 220 receiving the node information delivers and loads an application component necessary for operation to the corresponding node, and informs that the operation mode has been changed to use the resource (S570).

Then, the changed node information is transmitted to the multi-mode operation component 210 that manages node information, and the multi-mode operation component 210 confirms the change of the operation mode through the changed node information (S580). The manager component 230 informs the change of the operation mode. The control node / call processing node operation mode change module 234 of the multi-mode control manager component 230 confirms the change of the operation mode, and terminates the operation mode change operation (S590).

Herein, when it is determined in operation S530 whether the operation mode of the node can be changed in the multi-mode operation component 210, and it is confirmed that the operation mode cannot be changed, the control node / call processing node of the multi-mode control manager component 230 The operation mode change module 234 notifies that the operation mode change is impossible, thereby ending the operation mode change operation.

Through this process, the multi-mode supporting base station system can change the operation mode set in each node.
