Abstract
A method and system allowing a mobile phone user to “opt in” to requests with multiple response options, to respond indicating that user wishes not to be tracked, or to respond indicating some information about state, possibly in addition to PVT information. The user has options besides allowing ping responses or turning off GPS tracking. When a ping is received, user chooses whether or not to opt in to the ping. The user may refuse to respond, to respond normally with or without PVT or other information, or to respond saying only that the mobile phone is turned on. GPS tracking continues to operate, so that upon return to normal responses, no cold start of GPS tracking is involved. More intelligent, such as for example rules-based, responses can be made to ping messages, in which GPS tracking interacts with a user interface to determine how to respond flexibly to pings.
