CIRCUIT SWITCHED FALLBACK

摘要

A user equipment (UE) adjusts a system information block (SIB) read abort timer to reduce mobile terminated circuit-switched fallback (CSFB) failure. In one instance, the UE receives a redirection list including frequencies to search for redirection and searches each frequency in the list to determine a strongest frequency. The UE then decodes short period system information blocks (SIBs) for a variable number of non-strongest frequencies until a strongest short period SIB is received. The UE adjusts a SIB read abort timer based on a signal quality of the strongest frequency and the variable number.

1. A method of wireless communication, comprising:
receiving a redirection list including frequencies to search for redirection; searching and measuring each frequency in the list to determine a strongest frequency; decoding short period system information blocks (SIBs) for a variable number of non-strongest frequencies until a short period SIB of the strongest frequency is received; and adjusting a SIB read abort timer based at least in part on a signal quality of the strongest frequency and the variable number of non-strongest frequencies.
