20100296809METHOD AND APPARATUS FOR SERVICE PROTECTION - A method and apparatus for realizing service protection are provided. The method includes the following steps: determining paths corresponding to automatic protection switching (APS)/protection communication channel (PCC) overhead bytes that are available to all nodes in a service protection trail; selecting a path for service protection from the determined paths corresponding to the APS/PCC; and using the selected path for implementing the service protection. Therefore, it is ensured that several service protections using APS/PCC may coexist in an optical transport network (OTN) and different kinds of service protection can be easily distinguished from one another.11-25-2010
20100211634METHOD AND SYSTEM FOR PROCESSING AN ADDRESS BOOK - A method and a system for processing an address book are provided. The method includes the following steps. A network address book (NAB) parses a user address book, and generates an acquisition request according to settings of the user address book. The NAB acquires contact information to be updated according to the acquisition request, and updates the user address book. The NAB synchronizes or transmits updated information of the user address book to a piece of user equipment (UE). By using the method, plenty of contact information is acquired according to the user settings. Therefore, the method solves the problems that the address books in the conventional technology have single-purpose functions and closely related to services and thus cannot serve as an independent function for providing services for the user. In addition, address book information on a plurality of UEs of the user can be updated synchronously, so that when one UE initiates address book information update, the address books on other UEs are updated accordingly. Therefore, the consistency between the address book information on the UEs is guaranteed.08-19-2010
