Apparatus and Associated Methods

1 . An apparatus configured to:

identify a particular motion state of a portable electronic device; and

vary the geographical location data sampling rate for the portable electronic device based at least partially on the identified particular motion state of the portable electronic device.

2 . The apparatus as claimed in claim 1 , wherein the apparatus is configured to identify a particular motion state based at least partially on one or more of detected: speed, direction, velocity, acceleration, deceleration, forces, torque, and/or change in any of these quantities experienced by the portable electronic device.

3 . The apparatus as claimed in claim 1 , wherein the particular motion state is selected from a group comprising one or more of: stationary, walking, running, cycling and/or in-vehicle.

4 . The apparatus as claimed in claim 1 , wherein each of the motion states is associated with a particular sampling rate, the apparatus being configured to vary the geographical location sampling rate based at least partially on the particular sampling rate associated with the particular identified motion state.

5 . The apparatus as claimed in claim 1 , wherein each of the particular motion states is associated with a particular weighting, the apparatus being configured to accumulate the respective weightings of one or more identified motion states and compare the accumulated weighting value to a predetermined threshold to determine the sampling rate.

6 . The apparatus as claimed in claim 1 , wherein the apparatus is also configured to:

identify a particular energy level of the portable electronic device; and

vary the geographical location data sampling rate for the portable electronic device based at least partially on the identified particular motion state and the identified particular energy level of the portable electronic device.

7 . The apparatus as claimed in claim 6 , wherein the apparatus is configured to be able to access a policy table, wherein the policy table stores a plurality of sampling rates, each sampling rate being associated with a particular motion state and a particular energy level of the portable electronic device, the apparatus being configured to vary the geographical location data sampling rate in accordance with the particular sampling rate associated with the identified motion state and the identified energy level of the portable electronic device.

8 . The apparatus as claimed in claim 7 , wherein the policy table is generated/populated in accordance with a Markov Decision Process.

9 . A processor configured to:

identify a particular motion state of a portable electronic device; and

vary the geographical location data sampling rate for the portable electronic device based on the identified particular motion state of the portable electronic device.

10 . An apparatus comprising the processor of claim 9 , and a memory including computer program code, wherein the memory and the computer program code configured to, with the processor, cause the apparatus at least to

identify a particular motion state of a portable electronic device; and

vary the geographical location data sampling rate for the portable electronic device based on the identified particular motion state of the portable electronic device.

11 . A portable electronic device comprising the apparatus of claim 1 .

12 . A method comprising,

identifying a particular motion state of a portable electronic device; and

varying the geographical location data sampling rate for the portable electronic device based on the identified particular motion state of the portable electronic device.

13 . A method as claimed in claim 11 , wherein identifying a particular motion state based at least partially on one or more of detected: speed, direction, velocity, acceleration, deceleration, forces, torque, and/or change in any of these quantities experienced by the portable electronic device.

14 . A computer readable medium comprising a computer program stored thereon, the computer program comprising:

program code for identifying a particular motion state of a portable electronic device; and

program code for varying the geographical location data sampling rate for the portable electronic device.
