Problems solved by technology

[0010] The purpose of the present invention is to provide a kind of interlayer switching method in the WCDMA layered network at the shortcoming of above-mentioned prior art, thus solve the mobile station that is in compressed mode state when realizing interlayer switching in layered network structure If the proportion is too large, it will cause the problem of reducing system performance, and when the mobile station switches from a macro cell to a micro cell, it may quickly switch back to the macro cell "ping-pong" handover problem

Embodiment Construction

[0047] In order to make it easier for those skilled in the art to understand and realize the present invention, the embodiments of the present invention are described in conjunction with the accompanying drawings.

[0048] The interlayer switching measurement in the WCDMA layered network of the present invention adopts an intermittent measurement method. That is to say, after a period of measurement, if the mobile station does not find a suitable target layer cell, it can stop the measurement first, and then re-initiate the measurement after a period of time when the wireless environment has changed, and continue to search for a suitable target layer cell.

[0049] According to the present invention, the so-called inter-layer handover refers to: since each layer in the network will estimate the speed state of the mobile station, when it is found that the current estimated speed of the mobile station does not match the layer it is in, that is, the speed of the mobile station Wh...

Abstract

Present invention provides interlayer switch method for WCDMA layering network. It contains measuring traveling platform speed, when traveling platform speed is quickly and existing higher cell, then adopting Intermission measurement mode switching to higher cell, when traveling platform speed is normal, then staying in said layer, when traveling platform speed is slow, and existing lower cell, then adopting Intermission measurement mode switching to lower cell. Said invention reduces influence of start compression mode to system performance, and avoiding ping-pong switching.

Description

technical field [0001] The invention relates to network communication technology, in particular to an interlayer switching method in a WCDMA layered network. Background technique [0002] In a WCDMA (Wideband Code Division Multiple Access) mobile communication system, in order to meet the requirements of multiple high-speed data services, a large enough system service capacity is required. Generally, the system capacity per unit area is increased by reducing the cell coverage radius. In hotspot areas, the traffic is absorbed by adding micro cells; in dense urban areas with particularly high traffic, continuous coverage of small cells is realized. But for mobile stations moving at high speed, micro cells will bring many problems, such as increased call drop rate, increased system signaling load, and reduced system capacity. [0003] In order to solve the above problems, a layered cell network structure is introduced, and a continuous coverage layer of macro cells is added on...
