<P>PROBLEM TO BE SOLVED: To allow call control applications and call control information updated in a main memory to be stored in nonvolatile memory. <P>SOLUTION: A call control unit generates a RAM disk region section on a volatile memory, loads call control applications and call control information stored in a nonvolatile memory to the volatile memory for call processing, and stores write information to the nonvolatile memory in the RAM disk region. The call control unit includes an update detection processing means for detecting write information to a region in the nonvolatile memory for storing the call control application and call control information loaded to the volatile memory by call processing from write information of a RAM disk region, and a write processing means for writing write information to regions of call control applications and call control information out of write information in a RAM disk region to the nonvolatile memory, based on detection by the update detection processing means. <P>COPYRIGHT: (C)2010,JPO&INPIT |
