Abstract: Disclosed are a signaling optimization method and device, to resolve a problem of heavy signaling overheads and long data transmission delay when a user equipment (UE) accesses a network side. The method includes: receiving, by the UE, configuration information sent by a first network side device, where the configuration information includes a list, and the list is a cell list or a base station list; and entering, by the UE, an intermediate state according to the configuration information, where the intermediate state means that: when the UE stores context information of the UE, if the UE moves and a cell movement range falls within a coverage area of a cell or a base station included in the list, the UE performs cell reselection according to the list. Embodiments of the present disclosure are applicable to optimization of signaling transmission between the UE and a network side.

Abstract: This application provides a data processing method and apparatus, and a computer storage medium. When a PDCP entity over a UM DRB is re-established, or when a cell handover occurs and the PDCP entity over a UM DRB uses a key used before the handover, the PDCP entity determines a first SDU, where the first SDU is an SDU that is associated with a sequence number by the PDCP entity but whose corresponding data has not been transmitted through an air interface; and delivers a PDU corresponding to the first SDU to an RLC entity. Data corresponding to the first SDU is redelivered, to avoid a data packet loss caused by preprocessing of the PDCP entity.

Abstract: The present application discloses methods and apparatus for resuming a radio access network (RAN) connection by an inactive terminal device. An example method disclosed herein includes the step of sending, by a terminal device, connection resumption request information to a first RAN element, where the first RAN element corresponds to the cell on which the terminal device currently camps and is a RAN element indicated by configuration information of a master cell used by the terminal device when in a connected state. The terminal device receives acknowledgement information sent by the first RAN element and resumes a connection to a second RAN element based on the acknowledgement information, where the second RAN element is a RAN element indicated by the configuration information of the secondary cell.
