Abstract

The embodiment of the invention discloses a self-configuration method and system for a double-connection small base station in a heterogeneous network, and the method comprises the steps that an SeNB obtains the address of a network management system and uploads the equipment capability information of the SeNB and the parameter information of a transmission layer to the network management system; the network management system determines an ownership MeNB of the SeNB, requests the ownership MeNB to activate a new cell, transmits the transmission layer parameter information and configuration information of the SeNB to the new cell, and transmits the transmission layer parameter information of the MeNB to the SeNB; the SeNB and the ownership MeNB build a data transmission X2 interface, and the SeNB carries out corresponding parameter configuration according to configuration parameters transmitted by the ownership MeNB; the network management system also configures neighborhood self-optimizing ANR measurement and target PCI for the ownership MeNB and a user terminal in a nearby neighborhood base station of the ownership MeNB if the neighborhood relation of the SeNB and the PCI are not configured in advance, and the ownership MeNB determines whether to add the neighborhood relation or to request the network management system to modify the target PCI or not according to ANR measurement results uploaded by the user terminal. According to the embodiment of the invention, the method and system achieve quick deployment of the double-connection small base station in the heterogeneous network.

Description

technical field [0001] The invention relates to communication technology, in particular to a self-configuration method and system for a dual-connection small base station in a heterogeneous network. Background technique [0002] With the increase of user demand for long-term evolution (LTE) network capacity and coverage, it is necessary to introduce small base stations (SmallCell) in the future LTE network to absorb traffic and enhance coverage, but the introduction of traditional small base stations will increase to a certain extent. Interference between nodes and negative impact on terminal mobility. In the standard research of 3GPPR12, the topic of Small Cell Enhancement (SCE) mainly studies related issues such as capacity and mobility in heterogeneous networks. This research topic focuses on the architecture of separating the user plane and the control plane, such as figure 1 As shown in , it is a schematic diagram of the network topology and protocol stack architectur...
