Problems solved by technology

However, figure 2 shows that even if the cell size information is provided to the UE, existing mobility state methods for speed estimation still have problems: differences in small cell layout in different areas can lead to very different HO counts, even if the small cell size is determined by Provided to UE
This single sample without any averaging would be unusable, taking into account the fact that the UE may move tangentially through small cells and the effects of fading and shadowing

Abstract

One embodiment of the method of estimating mobility of a user equipment includes obtaining (S510, S520, S710, S715) location information of at least one base station that participated in a handover of the user equipment, and estimating (S530, S540, S720- S750) a mobility of the user equipment based on the obtained location information.

Description

Background technique [0001] Heterogeneous networks (HetNet or HTN, heterogeneous network) are now being developed, where smaller sized cells are embedded in the coverage area of ​​larger macro cells, and small cells can even communicate with umbrella The common macro cells share the same carrier frequency, mainly to provide increased capacity in target areas where data traffic is concentrated. Such a heterogeneous network tries to effectively increase the overall capacity of the wireless network by taking advantage of the spatial variation in the distribution of users (and services). Those smaller sized cells are commonly referred to as pico cells or femto cells, and will be collectively referred to herein as small cells for purposes of description. [0002] There are several scenarios that require performance improvements for speed-aware mobility operations in HTNs. The speed information used at the network can be used to improve network mobility decisions. For example, us...
