A fast synchronization method for system reorganization address book based on Beidou broadcast

Abstract

The invention discloses a rapid synchronization method for system reorganization address book based on Beidou broadcast. In this method, the reorganization initiator broadcasts the reorganization signaling through Beidou broadcast, each node switches to the standby channel after receiving it and sends a receipt, and then the initiator sends the differential parameter compressed packet point-to-point through the standby channel, and each node receives and decompresses the application. , after the difference parameter takes effect, the receipt is sent again, and finally each node switches back to the channel based on the address book. The invention focuses on designing the organization form of the difference parameter in the system reorganization process, the distribution of the difference parameter and the process of updating the initial state system address book based on the difference parameter. The present invention transmits only the parameter information of the changed node that has been adjusted when distributing the recombination parameter package, and does not include the parameter information of the node that has not changed.

Description

technical field [0001] The invention relates to a method for fast synchronization of system reorganized address books, in particular to a method for fast synchronization of system reorganized address books based on Beidou broadcast. Background technique [0002] The address book is a collection of certain physical entities and communication-related attributes such as addresses, telephone numbers, and mailboxes, such as telephone yellow pages, mobile phone address books, corporate address books, and class address books. In the information system, the address book is used to store the name, number and communication-related parameters of each node. Information systems form the basis for the operation of modern social organizations and are used in all aspects of social activities. Some outdoor activities, such as geological exploration, surveying and mapping, ecological protection and even military operations, face complex terrain environments, and participants and equipment may...

Problems solved by technology

[0004] In the existing mainstream solutions, the parameter data of all nodes is transmitted during the distribution of the reorganized parameter package, which includes not only the parameter information of the adjusted node with changes, but also the parameter information of the non-changed nodes that are not adjusted. The amount of network transmission data It is relatively large, and the transmission takes a long time, especially when the number of system nodes expands to a certain scale, this transmission short board is especially exposed
