Methods and systems for synchronizing serial numbers (SN) for multi-point widebreak services

Abstract

This invention derives a method and system for synchronizing sequence numbers (SN) for multipoint wideband transmission services. This method involves: receiving the first radio interface signal (SN) to obtain the best multipoint wideband transmission service in the first cell and the second radio interface signal (SN) to obtain the best multipoint wideband transmission service in the second cell; and arrange the data packets of the first multipoint wideband service according to the first radio interface SN and the second radio interface SN, where the first radio interface SN and the second radio interface SN are placed in the same set of SNs and the first radio interface SN and the second radio interface SN are at least partially different.
