Problems solved by technology

Each Short ToS is accompanied by two unnecessary switching, which increases system resource overhead and may also cause interruption of user data transmission
[0008] Handover failure rate and short-stay rate are contradictory, and a reduction in handover failure rate often leads to an increase in short-stay rate

Embodiment Construction

[0027] In order to express the object, technical solution and advantages of the present invention more clearly, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0028] In the embodiment of the present invention, the UE adaptively adjusts the size of the L3 filter factor used in the measurement according to the different mobile states. By adaptively adjusting the size of the L3 filter factor k, the measurement result can more accurately reflect the real Changes in channel quality to improve handover performance. Specifically, when the UE is moving fast, by reducing the value of the L3 filter factor k, the UE is more prone to handover, thereby reducing the handover failure rate, at the cost of slightly increasing the short-stay rate; when the UE is moving slowly, by Increasing the value of the L3 filter factor k makes the UE less prone to handover, thereby reducing the short-stay rate, at th...

Abstract

A method for improving heterogeneous network switching performance includes that a UE (user equipment) measures RSRP (reference signal received power) and RSQR (reference signal received quality) in each symbol in a single subframe; the averaged RSRP subjected to linear additivity and the averaged RSQR subjected to linear additivity are filtered for the first time to acquire a first measured value; the first measured value is filtered for the second time to acquire a second measured value by combining a filter factor k; the UE initiatively reports auxiliary information including corresponding information of the second measured value, and a network side performs switching judgment according to the auxiliary information. By the method, the heterogeneous network switching performance can be improved, while compromise of switching failure and short stay rate can be achieved.

Description

technical field [0001] The present application relates to the technical field of communications, and more specifically, to a method for improving switching performance of a heterogeneous network. Background technique [0002] As the types of data service applications become more and more extensive, and users' demand for data rates increases, the traditional network architecture based on cellular coverage can no longer meet the needs of service characteristics, mainly reflected in two aspects: (1) the traditional cellular network Indoor coverage is poor; (2) The capacity of traditional cellular networks in business hotspots is far from meeting demand. [0003] The reason why the traditional cellular network has poor indoor coverage is that the indoor penetration loss is relatively large. In addition, the operating frequency of the next-generation wireless communication system is relatively high, so it is difficult for indoor users to obtain high throughput. Statistics show t...
