一种节省存储空间的用户群组管理方法、系统及移动终端
摘要：
本发明公开了一种节省存储空间的用户群组管理方法、系统及移动终端，通过给每个联系人设置一个M位的十六进制群组编码，M位的群组编码最多可对应4×M个群组；在获取联系人所在的群组时，将群组编码转换成4×M位的2进制数，所述2进制数的每一位对应一个群组，其中，所述2进制数某一位为1则表示联系人被收录在该位对应的群组中，所述2进制数某一位为0则表示联系人未被收录在该位对应的群组中；读取联系人群组编码的2进制数获取该联系人所在的群组。由此，无需增加存储空间即可将联系人和群组关联起来，在进入群组后，只需根据群组对应的群组编码的二进制数即可找到群组中的联系人，极大的节省了存储空间。
摘要（英）：

The invention discloses a storage-space-saving user group management method, system and mobile terminal. An m-bit hexadecimal group code is set for each contactor, and the m-bit hexadecimal group code maximally correspond to 4*M groups. The group code is converted into 4*M-bit binary number during obtaining the group of a contact, each bit of the binary number corresponds to one group. When one bit of the binary number is one, the contactor is stored in the group corresponding to the bit. When one bit of the binary number is zero, the contactor is not stored in the group corresponding to the bit. The group of the contact is obtained by reading the binary number of the contact group code. No extra storage space is needed to associate the contactors with the groups. After entering the group, the contactor can be found in the group according to the binary number of the contact group code corresponding to the group. The storage space is greatly saved.
