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: A measurement control method is disclosed. A user equipment (UE) receives measurement indication information from a network and initiated by the network. The measurement indication information includes an identification of an area of a current cell where the UE is located. The UE determines whether the identified area is within a preferred area of the UE. The UE performs a measurement process if the identified area is not within a preferred area of the UE.

Abstract: A link re-establishment method, an apparatus, and a system are described. 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. The method and apparatus of the present disclosure address a 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.

Abstract: This application provides a transmission method and device. The method includes: receiving, by a first device, a first RRC message sent by a second device, where the first RRC message includes first data and identification information, and then sending, by the first device, the first data and the identification information to a donor eNB of the first device by using a second RRC message. Because the first device and the second device send data by using an RRC message, network functions of the first device and the second device are simplified, and data transmission efficiency is increased after a plurality of relay nodes access an NB-IoT network.
