CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a continuation of International Application No. PCT/CN2014/081072, filed on Jun. 28, 2014, which claims priority to Chinese Patent Application No. 201310270843.9, filed on Jun. 29, 2013, Chinese Patent Application No. 201410103869.9 filed on Mar. 19, 2014, and Chinese Patent Application No. 201410192727.4 filed on May 8, 2014, all of which are incorporated herein by reference in their entireties.

TECHNICAL FIELD

Embodiments of the present disclosure relate to the field of communications technologies, and in particular, to a network communications method, apparatus, and system.

BACKGROUND

A heterogeneous network (HetNet) technology is a radio access network technology applicable to a multi-layer network. A conventional radio access network generally has only one network layer, which is referred to as a macro network layer, and a base station in a macro network (macro base station for short) needs to cover an entire macro network to provide continuous and uninterrupted services to users. In a HetNet, one or more micro network layers are added on a basis of a macro network layer, and a base station in a micro network (micro base station for short) has low transmit power and a coverage range that is much lower than that of a macro base station. Therefore, a micro base station is also referred to as a low power node (LPN). A micro base station is generally deployed at a coverage hole or a hot spot area of a macro base station to offload the macro base station, so as to improve a throughput rate of an entire network.
