US 8,265,625 B2 · Systems and methods for network entry management

Abstract

Systems and methods for network entry management are provided. The system includes a base station and a mobile station. The base station broadcasts synchronization channels (SCH) on multiple carriers, where the SCH may be hierarchical synchronization channel composed of primary synchronization channel (P-SCH) and secondary synchronization channel (S-SCH) which are used for timing, frequency synchronization, cell identification, etc. The carriers include at least a first carrier including at least one P-SCH and do not include a S-SCH. The mobile station scans the first carrier, and checks whether a P-SCH is broadcasted on the first carrier. If a P-SCH is broadcasted on the first carrier, the mobile station checks whether an S-SCH is broadcasted on the first carrier. If no S-SCH is broadcasted on the first carrier, the mobile station scans for a second carrier broadcasted by the base station.

A system for network entry management, comprising:

a base station broadcasting multiple carriers, wherein the carriers comprise a first carrier including at least one primary synchronization channel (P-SCH) and does not include a secondary synchronization channel (S-SCH);
and
a mobile station scanning the first carrier, checking whether a P-SCH is broadcasted on the first carrier, if a P-SCH is broadcasted on the first carrier, checking whether an S-SCH is broadcasted on the first carrier, and if no S-SCH is broadcasted on the first carrier, scanning a second carrier broadcasted by the base station.

A method for network entry management for use in a base station and a mobile station, comprising:

broadcasting multiple carriers by the base station, wherein the carriers comprise a first carrier including at least one primary synchronization channel (P-SCH) and does not include a secondary synchronization channel (S-SCH);
scanning the first carrier by the mobile station;
checking whether a P-SCH is broadcasted on the first carrier by the mobile station;
if a P-SCH is broadcasted on the first carrier, checking whether an S-SCH is broadcasted on the first carrier by the mobile station, and
if no S-SCH is broadcasted on the first carrier, scanning a second carrier broadcasted by the base station by the mobile station.
