Reducing mobile-terminated call set up by identifying and mitigating overlap between paging and system information broadcast
Abstract:
In a Universal Mobile Telecommunications (UMTS) system, a mobile device reads scheduling information for uplink interference (SIB7) from a Master Information Block, broadcasted on the Broadcast Channel (BCCH). The UE wakes up from the sleep during its periodic paging occasions and reads the paging indicator channel (PICH). If the UE needs to read the PCH, then the UE computes the timing of the next broadcast of SIB7 using the scheduling information broadcast in the MIB on BCCH. Knowing the timing of the next SIB7, the UE can determine if there is an overlap. If overlap is detected, the mobile device demodulates both the paging channel carried by the Secondary Common Control Physical Channel (S-CCPCH) and the broadcast channel carried by the Primary CCPCH, avoiding a mobile-terminated (MT) call setup delay by waiting for the next SIB7 broadcast, which depending upon a SIB7 repetition ranges from 360 msec to 2.56 seconds.
