Location requests and measurement responses in wireless communications networks and methods
A method for requesting location information, for example, Enhanced Observed Time of Arrival timing information, from mobile wireless communications in wireless communications networks. The exemplary location request ( 300 ) includes multiple response interval field ( 310 ) specifying intervals at which multiple responses to the location request must be sent or maximum intervals between which multiple responses to the location request must be sent, a final response time field ( 320 ) specifying a maximum time interval during which a final response to the location request must be sent, and an initial response time field ( 330 ) specifying when an initial response to the location request must be sent.
1. A method in a mobile wireless communications device, the method comprising:
receiving a network location request at the mobile wireless communications device;
sending multiple responses to the same network location request,
the multiple responses sent from the mobile wireless communications device;
obtaining multiple measurement information sets;
sending multiple responses to the same network location request includes sending the multiple measurement information sets; and
completing each of the multiple measurement information sets when a variance of multiple measurements on a plurality of signal sources satisfies a condition.

sending multiple responses to the same network location request,
the multiple responses sent from the mobile wireless communications device;
obtaining multiple measurement information sets;
sending multiple responses to the same network location request includes sending the multiple measurement information sets; and
completing each of the multiple measurement information sets when a rate of change of standard deviation of multiple measurements on a plurality signal sources satisfies a condition.
3. A method in a mobile wireless communications device, the method comprising:
receiving a network location request the mobile wireless communications device; and
sending multiple responses to the same network location request,
the multiple responses sent from the mobile wireless communications device,
each response including measurement information for a plurality of signal sources, and
sending each response when a variance of multiple measurements on each signal source of the plurality of signal sources satisfies a condition.
