Abstract

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.

Claims

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.

2. 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 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.

4. A method in a mobile wireless communications device, the method comprising:

receiving a network location request at 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,

sending each response when a rate of change of standard deviation of multiple measurements on each signal source of the plurality of signal sources satisfies a condition.
