摘要: 针对传统呼叫指纹算法在实际应用中识别准确率低、 识别对象局限性大、 识别时间长等问题, 在Hausdorff距离的基础上提出一种新的匹配算法, 从而提高了重入网用户识别的精度, 扩大了识别对象的适用范围.

关键词: 呼叫指纹, 重入网, Hausdorff距离, 转移概率矩阵

Abstract: In the light of many problems like the low accuracy on identification, the big limitness on the object of identification, taking more t ime, etc. for the arithmetic of traditional callfingerprint using the method which combines the callround identification with the IMEI identification, this thesis deals with an arithmetic which is based on the match of Hausdorff’s distance to improve the accuracy of identification and the extending of the scope of object.

Key words: callfingerprint, repeat network access, Hausdorff di stance, transfer probability matrix
