Start Type, Start Time, AllowDelay, Priority, Activity, etc. * Application Level information (provided by User via the Policy Table) includes: * - Application State Name, Weight, AppliedActivity, Pause, etc. * Global Priority Table (GPT) * - GPT defines relative priorities of the two stacks * - GPT consists of three parameters: Stack Activity, Priority of the activity (Normal, High, Urgent), and Global Priority Number * - GPT input: Stack Activity + Priority of the activity (Normal, High, Urgent) * - GPT output: Global Priority Number * Final Priority = GPT (Stack Activity + Priority of the activity) + .weight (in the Policy Table) * * # GPT for BLE + PROP # * ___________________________________________________________________________________________________ * | BLE Activity + Priority | 15.4 Activity + Priority | GTP value * ____________________________________________________________________________________________________ * | Connect -
