It is due to the identification and reduction of overlap with paging and system information information, decrease of setup lag to the portable machine

摘要

The universal Mobile telecommunication (UMTS) in the system, as for the portable machine, master information block (MIB) from the information channel (BCCH) with schedule information for the uplink interference which is reported (SIB7) you read. In degree of the periodic paging awakening from sleep, the page indicator channel (PICH) you read UE. When UE the paging channel (PCH) it is necessary to read, UE using the schedule information information in MIB with BCCH, calculates the information timing of following SIB7. When the timing of following SIB7 is known, to decide whether or not there is overlap, it is possible UE. When overlap is inspected, the portable machine recovers, both of the information channel which is carried by the paging channel and primary CCPCH it is carried the physical channel for secondary common control (S-CCPCH) by (mobile-terminated) to the portable machine (MT) evades the setting lag of call by waiting for the next SIB7 information which depends on the SIB7 repetitive range 2.56 seconds from 360 milli-second.
