Embodiment Construction

[0033] The specific implementation manner of the present invention will be described below in conjunction with the accompanying drawings.

[0034] The technical solution of the present invention is still described by taking the example of a two-layer network formed by the interlacing of macrocells and microcells.

[0035] At present, 3G base stations are developing in the direction of multi-carrier transceivers, and more and more base stations use multi-carrier transceivers. A new carrier can be added without adding sectors in the base station, and no new hardware components are added, but if image 3 As shown, if only a carrier with channel f1 is added to the microcell with channel f2, even if the newly added carrier is consistent with the channel of the macrocell, because no isolation sector is formed, the isolation between the macrocell and the macrocell cannot be achieved. The purpose of microcellular.

[0036] In order to achieve the purpose of effectively isolating mac...

Abstract

A method for realizing isolation in layered network includes setting two carriers in microcellular base station corresponding to staggered zone of microcellule and macrocellule as the first carrier f1 applying microcellular channel and the second one f2 applying microcellular channel then configuring different emission power for then, dividing emission signal of microcellular base station to be two paths of signals as the first path signal being sent to microcellular sector and the second one being sent to staggered zone of macrocellule and microcellule for forming isolation sector. The device for realizing said method is also disclosed.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a method and device for realizing isolation in a layered network. Background technique [0002] In the cellular communication system of the CDMA system, a network solution to solve network coverage and capacity is to adopt layered network technology. Introduce micro cells into the hierarchical network, set macro cells and micro cells into different levels, and use specific cell reselection and handover algorithms to assign users in idle or connected mode to macro cell layer or micro cell layer. Layers use different carriers. [0003] However, when the layered network does not have sufficient isolation, it is easy to cause frequent inter-frequency switching of users, resulting in a decrease in network quality. For example, a very typical scenario mentioned below, such as figure 1 As shown, the micro-cell coverage is used in a commercial building, using the f2 chann...
