摘要：
Different methods for network-based mobile positioning were compared experimentally. The Cell-id and TA method provided limited accuracy, the uncertainty ranging from 500 m to 3000 m for the median, dependant on area type. This could be reduced up to 25% by using alternative radii based on observations in the "doughnut" shaped prediction area. The Planning tool method improved the accuracy by approximately 30-50% compared to this in urban area. The Forced handover method provided the best overall performance. In rural area the improvement was approximately 40-55% compared to Cell-id and TA.
