Abstract: A small cell receives a dedicated synchronization signal Preamble sent through a first message by a user equipment UE in an idle state. The dedicated Preamble is allocated when the UE accesses a network for the first time. The small cell according to the dedicated Preamble queries whether a first signaling radio bearer SRB 1 and/or a second signaling radio bearer SRB2 of the UE are/is stored. If stored, the small cell replies in a second message to the UE that indication information that the SRB 1 and/or the SRB2 between the small cell and the UE do/does not need to be re-established or modified. An uplink radio resource control RRC message sent through a dedicated control channel DCCH by the UE is received.

Abstract: Embodiments of the present invention provide a method, a device, and a system for determining timing advance grouping. In one embodiment, a base station adds a component carrier (CC) for a user equipment (UE). The base station determines a timing advance (TA) group to which the added CC belongs. The TA group is a set of CCs that can share a TA. The base station sends identification information that identifies the TA group to the UE.

Abstract: A link re-establishment method, an apparatus, and a system are provided. The method includes: obtaining, by user equipment (UE), a MAC of the UE based on a NAS integrity key and a first MAC generation parameter, where the first MAC generation parameter includes an identifier of the UE; sending, by the UE, a re-establishment request message to a target RAN, where the re-establishment request message includes the MAC and the first MAC generation parameter; and receiving, by the UE, a re-establishment response message of the target RAN. The UE triggers, by sending the re-establishment request message, a CP functional entity to perform authentication on the UE. This resolves a prior-art problem that an excessively long time is consumed to re-establish a connection to a target RAN by using an RAU procedure, increases a speed of re-establishing a connection between UE and a network, and improves user experience.
