VERFAHREN ZUR BESTIMMUNG DER FRAMEZAHL EINES HYPERSYSTEMS, KOMMUNIKATIONSVERFAHREN UND -VORRICHTUNG

摘要

Embodiments of this application provide a hyper system frame number determining method, a communication method and apparatus. The method includes: determining, by an access network device, a first hyper system frame number HSFN and a first system frame number SFN, where the first HSFN and the first SFN are determined by the access network device based on a time at which enhanced discontinuous reception eDRX is enabled and a preconfigured time; determining, by the access network device, an HSFN adjustment value based on the first SFN and a second SFN, where the second SFN is an SFN used at the time at which the access network device enables the eDRX; and adjusting, by the access network device, the first HSFN to a second HSFN based on the HSFN adjustment value, and updating the second HSFN based on the second SFN.
