Communication control device and control method

Abstract

If the data type of unprocessed data is not changed when the operation of control units (102a, 102b) is changed, table A' of the control unit (102b) corresponding to table A of the control unit (102a) is all cleared, and table B is created in an area different from that of table A'. The data of old type stored in table A is converted to data of new type. The data of new type is stored in table B. When the conversion of the old type to the new type is started, the differential data (data of the old type) written in the control unit (102a) is stored in table A' the data of which is cleared. The stored differential data is converted data of the new type. The data of the new type is written in table B. The related data of table A' is cleared. When differential data disappears by the type change, the system is switched from the operating one to the standby one.

Description

technical field [0001] The present invention relates to a communication control device and a control method, and more particularly to a communication control device and a control method for a communication device which is based on continuous operation. Background technique [0002] In recent years, due to the popularity of communication networks and the diversification of user needs, the software update of communication control devices is no longer limited to the correction of simple defects in the past, and the proportion of function additions for improving services has increased. Depending on the type of resource data, the possibility of change and expansion increases. [0003] Conventionally, there is a method disclosed in (Japanese) Unexamined Patent Publication No. 5-89061 as a method for updating software of a control device or the like. [0004] Since the continuous operation of the communication control device cannot be stopped for a long time,...

Problems solved by technology

However, in this method, when the software update is repeated along with the type conversion of the data, there is a possibility that overhead is generated and the processing performance of the communication device as a whole may be lowered.
