摘要： 为解决移动用户分组问题，提出一种基于地理位置的移动用户群组划分方法。根据已有用户统计信息，计算用户分布密度，利用用户密度及多峰高斯分布函数，找出各个高斯分布的顶点、特征半径、顶点对应群组的中心位置，以及特征半径对应群组的半径，从而划分出各个群组。实验证明，该方法能够合理划分移动用户群组，易于控制群组规模。

Abstract: For mobile user group, this paper formulates a method based on the distribution of the mobile users. It calculates the population densities by the statistics of the mobile users. It finds the peak and characteristic radius of each Gaussian distribution according the multi-peaks Gaussian distribution model and densities. The peak and characteristic radius are the centre and radius of the group respectively. It gets all the groups. This method can group users reasonably, and control the center and the scale of the groups easily.
