    Abstract: A method and apparatus facilitates location tracking of a portable subscriber unit (122) in a radio communication system including a plurality of cells for providing radio communications with the portable subscriber unit (122). The plurality of cells are partitioned into subzones (402), a subzone (402) comprising at least one cell and utilizing at least one control channel. Each subzone (402) is assigned one of N subzone color codes (606). Adjacent subzones (402) have different subzone color codes (522), and same-valued subzone color codes (522) are reused in non-adjacent subzones (606). Control information is transmitted throughout each subzone (402) on the control channel (608) by a fixed portion (102) of the radio communication system. The control information includes the subzone color code (522) of the subzone (402). The portable subscriber unit (122) detects changes in the subzone color code (522), and thereafter, registers with the fixed portion (102) of the radio communication system in response.

    Abstract translation: 一种方法和装置有助于包括用于提供与便携式用户单元(122)的无线电通信的多个小区的无线电通信系统中的便携式用户单元(122)的位置跟踪。 多个小区被划分成子区域(402),包括至少一个小区的子区域(402)并且利用至少一个控制信道。 每个子区域(402)被分配为N个子区域颜色代码之一(606)。 相邻的分区(402)具有不同的子区域颜色代码(522),并且相邻的子区域颜色代码(522)在不相邻子区域(606)中重新使用。 通过无线电通信系统的固定部分(102)在控制信道(608)上的每个子区(402)中发送控制信息。 控制信息包括子区域(402)的子区域颜色代码(522)。 便携式用户单元(122)检测子区域色码(522)的变化,然后响应于无线电通信系统的固定部分(102)进行注册。
