This invention relates to a method for realizing self-organized network synchronization system based on TD-SCDMA, which broadcasts re-defined SS field in the TD-SCDMA sub-frame structure with the help of a GPS device loaded by mobile terminals and full network nodes adjust the time of themselves according to the synchronous offset adjustment information loaded by the SS field so the mobile self-organized network nodes are unified to the synchronous clock of the TD-SCDMA cellular network, in which, the process of synchronization includes four steps: a stage of computing synchronization offset,a stage of setting up a hierarchical structure, a stage of broadcasting SS field and a stage of adjusting synchronization offset.
Description
Realization method of ad hoc network synchronization system based on time division synchronous code division multiple access technical field The present invention utilizes the characteristics of the TD-SCDMA (Time Division Synchronous Code Division Multiple Access) air interface, and builds a TD-SCDMA-based The method for synchronizing the mobile ad hoc network of SCDMA belongs to the technical field of TD-SCDMA communication. Background technique TD-SCDMA, as the third-generation mobile communication standard proposed by China, uses advanced technologies such as time division duplexing, uplink synchronization, smart antennas, joint detection and relay handover, but still has the shortcomings of cellular coverage blind spots and insufficient service types. The mobile self-organizing network has the characteristics of no center and self-organization. Using the TD-SCDMA air interface to build a mobile ad hoc network can not only take advantage of the characteristics of TD-S...
