Software feed forward strategy to avoid hand-shaking delays between software and firmware

摘要

Methods for enabling a mobile device to efficiently resolve coexistence issues in a DSDA configuration by utilizing a feed forward strategy to avoid hand-shaking between software-implemented operations and firmware. The mobile device may employ a dual subscription, dual active (or “DSDA”) configuration in which two or more subscriptions may be associated with concurrently active communications, such as voice or data calls. The mobile device may be configured to predict activity associated with the concurrently active subscriptions, such as determining operations likely to be performed in a future time period. Such predicted activity information, as well as predefined actions and priority information, may be provided to a library common to both subscriptions. Firmware of the subscriptions may use the common library to detect current conflicts, such as desense, as well as actions to perform to resolve coexistence issues, such as blanking operations.

1. A method for a dual-subscriber identity module (SIM), dual-active (DSDA) mobile device to efficiently resolve coexistence issues by utilizing a feed forward strategy, comprising:
initializing a coexistence manager configured to schedule at least a first subscription and a second subscription; storing, in the coexistence manager, information provided in advance by software-implemented operations of the first subscription and the second subscription; detecting whether a coexistence issue will exist for an activity interval within a current time period using firmware of the first subscription and the second subscription and the information provided to the coexistence manager in advance; and scheduling operations with the firmware of the first subscription and the second subscription using the information provided to the coexistence manager in advance of when the coexistence issue will exist.
