摘要： A device for compressing vertex data in three-dimensional (3D) image data includes a codebook design module and a codeword search module. The codebook design module is configured for: grouping residual vectors of vertices in 3D image data for codebook design; generating, for each group of residual vectors, a sub-codebook formed by a specified number of codewords; and sending the generated sub-codebook corresponding to a group of residual vectors to the codeword search module. The codeword search module is configured for: receiving a sub-codebook sent by the codebook design module; searching for a codeword of optimal match of a to-be-compressed residual vector of a vertex in 3D image data to be compressed; and taking an index of the codeword of optimal match and an index of a sub-codebook where the codeword of optimal match is located as compressed data of the vertex. A method for compressing vertex data in 3D image data is further disclosed. With the disclosure, it is possible to save codeword storage space, enhance encoding quality, improve a compression ratio of vertex data, and increase a compression efficiency.

摘要： The present disclosure relates to a method, a terminal and a system for achieving differential charging of a fixed wireless phone among cells. The method comprises determining whether a terminal position is updated and generating position updating information when the terminal position is updated; sending the position updating information to a server so that the server parses the position updating information based on a preset charging policy and sends request information for changing the charging policy to a charging centre when the charging policy of the terminal needs to be changed. The present disclosure changes the charging policies in real time for fixed wireless phone products which need to distinguish the charging rules of different cells, thus solving the problem of charging for mobile operators in the process of popularizing fixed wireless phone products.
摘要翻译：本公开涉及用于在小区内实现固定无线电话的差分充电的方法，终端和系统。所述方法包括：确定终端位置是否被更新，并且当终端位置被更新时产生位置更新信息; 向服务器发送位置更新信息，使得服务器基于预设的计费策略解析位置更新信息，并且当需要改变终端的计费策略时，向计费中心发送用于改变计费策略的请求信息。本公开实时改变了需要区分不同小区的计费规则的固定无线电话产品的收费政策，从而解决了在普及固定无线电话产品过程中为移动运营商收费的问题。
