Abstract
A method for shortening a circuit switch fallback (CSFB) performing time includes determining a plurality of weighting values each associated with one of a plurality of frequencies to be measured during a CSFB procedure, determining a frequency measurement sequence for scheduling the frequencies to be measured in sequence according to the determined weighting values, and measuring a signal quality on the frequencies according to the frequency measurement sequence.
Claims28
A communication apparatus, comprising:
- a radio frequency (RF) signal processing device, for processing a plurality of RF signals transmitted to or received from a serving cell;
- a baseband signal processing device, for processing a plurality of baseband signals;
- and
- a processor, for controlling operations of the RF signal processing device and the baseband signal processing device,
- wherein the processor determines whether performing a circuit switch fallback (CSFB) procedure is required, and when performing the CSFB procedure is required, the processor further determines a plurality of weighting values each associated with one of a plurality of frequencies to be measured during the CSFB procedure, wherein the plurality of frequencies to be measured are corresponding to candidate target cells, determines a frequency measurement sequence for scheduling the frequencies to be measured in sequence according to the determined weighting values and measures a signal quality on the frequencies according to the frequency measurement sequence.
A method for shortening circuit switch fallback (CSFB) performance time, executed by a communication apparatus camping on a serving cell, comprising:
