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 buffer status report processing method and an apparatus are disclosed. A network device determines a logical channel or a logical channel group for which a separate buffer status report BSR needs to be reported, and sends separate-BSR reporting indication information. A terminal device receives the separate-BSR reporting indication information sent by the network device, and reports the separate BSR for the logical channel or the logical channel group indicated in the separate-BSR reporting indication information. The network device receives the separate BSR reported by the terminal device, and determines, based on the separate BSR, uplink buffer data amount information corresponding to the logical channel or the logical channel group. According to the BSR processing method, resource scheduling accuracy of the network device is improved.
