Abstract

The embodiment of the present invention discloses a self-configuration method and system for a dual-connection small base station in a heterogeneous network, wherein the method includes: the SeNB acquires the address of the network management system and reports the SeNB's device capability information and transmission layer parameter information to the network management system ; The network management system determines the MeNB of the SeNB, requests the MeNB to activate the new cell and sends the transmission layer parameter information and configuration parameters of the SeNB to it, and sends the transmission layer parameter information of the MeNB to the SeNB; the SeNB and the MeNB establish a data transmission X2 interface And the SeNB performs corresponding parameter configuration according to the configuration parameters sent by the home MeNB; if the neighbor cell relationship and PCI of the SeNB are not pre-configured, the network management system also configures neighbor cell self-optimization ANR measurement and The target PCI is configured, and the home MeNB determines whether to add a neighbor relationship or requests the network management system to modify the target PCI according to the ANR measurement result reported by the user terminal. The embodiment of the present invention realizes the rapid deployment of the dual-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 (Small Cells) in the future LTE network to absorb traffic and enhance coverage, but the introduction of traditional small base stations will to a certain extent Increases interference between nodes and negatively impacts terminal mobility. In the standard research of 3GPP R12, 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 architec...
