determine, based on the at least one identifier, whether an expected mobility status of the signal source is mobile or stationary;

determine whether a first position estimate determined using one or more signal sources expected to have respective mobility status of mobile differs by more than a threshold amount from a second position estimate determined without using at least one of the one or more signal sources expected to have respective mobility status of mobile; and

indicate that a confidence is low in the first position estimate based on the first position estimate differing by more than the threshold amount from the second position estimate.

13 . The apparatus of claim 8 , further comprising:

means for collecting one or more observations indicative of an actual mobility status of the signal source being that the signal source is mobile; and

means for providing an indication not to use the signal source to determine a position of a mobile device based on the one or more observations being indicative of the actual mobility status of the signal source being that the signal source is mobile.

14 . The apparatus of claim 8 , further comprising:

means for determining whether a first position estimate determined using one or more signal sources expected to have respective mobility status of mobile differs by more than a threshold amount from a second position estimate determined without using at least one of the one or more signal sources expected to have respective mobility status of mobile; and

means for indicating that a confidence is low in the first position estimate based on the first position estimate differing by more than the threshold amount from the second position estimate.
