Using client-specific RGS to improve performance on multi-SIM and multi-RAT devices

摘要

Various embodiments provide methods implemented in a mobile communication device (e.g., a multi-RAT communication device) for maintaining at least one separate RGS value for each of a plurality of RATs operating on the mobile communication device. Specifically, a device processor on the mobile communication device (e.g., a crystal oscillator manager) may maintain a separate, up-to-date RGS value for each of the plurality of RATs and may associate each of the plurality of RATs with their respective RGS values. By keeping track of the plurality of RATs' respective RGS values, the device processor may ensure that an appropriate RGS value is used to facilitate each RAT's individual operations, such as acquisition/re-acquisition operations, sleep scheduling calculations, and handover/inter-RAT measurement operations. As a result, various embodiments may improve the performance of each RAT and the overall performance of the mobile communication device.

1. A method implemented by a mobile communication device for improving performance of a plurality of radio access technologies (RATs) on the mobile communication device, comprising:
obtaining frequency error values for each of the plurality of RATs; associating the obtained frequency error values with each of the plurality of RATs and with at least one attribute based on times at which the frequency error values for the plurality of RATs are obtained, wherein an attribute comprises one of a temperature of the mobile communication device or a temperature of a crystal oscillator on the mobile communication device; and storing the obtained frequency error values and the associations of the obtained frequency error values.
