Publication number: 20100153777Abstract: A program updating system having correction storage units and methods thereof are described. The control unit checks the first setting section of the first storage unit to determine whether the first setting data associated with the second storage unit is stored in the first setting section. When the first setting data is stored in the first setting section, the control unit reads the first setting data and writes the first setting data to the second storage unit. The first setting data includes a first correcting address and a first correcting code corresponding to the first correcting address. The second storage unit stores a first setting data transmitted from the first setting section. The control unit compares an executed address of the original program with the first correcting address. When the executed address is identical to the first correcting address, the control unit replaces a first error code corresponding to the executed address with the first correcting code.Type: ApplicationFiled: April 27, 2009Publication date: June 17, 2010Inventor: Yao-chung Hu

Patent number: 6393101Abstract: A method is provided for determining whether the state of a telecommunications switch (110) is adequate for a software upgrade or retrofit. A report stream of text messages relating to the state of, and events occurring on, the telecommunications switch is stored (200) by a server (102). Predetermined messages are detected in the report stream, including messages indicating hardware errors, alarms and other errors (202). The predetermined messages have a numerical value associated therewith (204). The numerical value reflects a probability of failure of a retrofit if the message is detected. As the predetermined messages are detected, their numerical values are accumulated into an accumulated value (206). The time period the report stream covers is determined and compared against an expected time (216). If the time period covered by the report stream does not exceed an expected time, then a determination regarding suitability for upgrade may not be reliable (222).Type: GrantFiled: November 1, 1999Date of Patent: May 21, 2002Assignee: Lucent Technologies Inc.Inventors: Alvin Barshefsky, Shao-Kuang Hu, Yao-Chung Hu, Murali Ramakrishnan, John Frank Saban, Rickey Joseph Spiece, Charles Robert Strohm
