Abstract

The invention discloses a communication method. The communication method comprises the following steps: sending a request message to a micro-network node by user equipment, so that the micro-network node sends an indication message to a macro-network node; receiving an uplink resource UG transmitted by the macro-network node according to the indication message; and transmitting an uplink signal oruplink data to the macro-network node according to the uplink resource UG. The embodiment of the invention also provides corresponding equipment and system. According to the technical scheme of the invention, the micro-network node participates in network access of the user equipment, so that the UE can quickly access the network, and the access delay of the UE is reduced.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a communication method, device and system. Background technique [0002] In a network deployment scenario, there are two different network nodes, namely, an evolved base station (EvolvedNodeB, eNB) and a small cell node (Small Cell Node, SCN). The eNB and the SCN respectively control one or more cells, and the frequencies used by the cells of the eNB and the SCN may be different. The cell of the eNB has a larger coverage area and may be called a macro cell; the cell of the SCN has a smaller coverage area and may be called a small cell. [0003] In the prior art, if any of the following situations occurs: [0004] The time alignment timer (Time Alignment Timer, TAT) of the user equipment (User Experiment, UE) for the macro cell expires, and the UE has uplink data or signaling that needs to be sent to the eNB. [0005] The UE has no resource for sending a schedulin...
