In particular, the location sensing service may passively collect location coordinates of the device using requests made by third party applications. The location sensing service may receive a signal comprising an intent for a location request in response to a change in the user activity or in response to a change in a cellular identification of the device. The device may determine that a time elapsed from a previous location request and a time corresponding with receiving one or more of the signals exceed a time threshold and, based thereon, request a location coordinate of the device. ## Claims ### Claim 1 A device, comprising: one or more embedded sensors configured to detect movement of a user of the device; a non-transitory memory storage storing instructions; and one or more processors in communication with the non-transitory memory storage and the one or more embedded sensors, wherein the one or more processors execute the instructions to perform operations including: passively collecting location information of the device based on one or more requests from a third party application or service on the device; initiating a first intent for a location request requesting a current location of the device, based on a first measured movement in a first period of time exceeding a threshold; determining a second measured movement in a second period of time after the initiating; determining, based on the second measured movement being less than the threshold, that a duration of time between a previous collection of location information of the device and the initiation of the first intent for the location request exceeds a first time threshold; and based on the determining that the duration of time exceeds the first time threshold, requesting the current location of the device. ### Claim 2 (depends on 1) The device of claim 1, wherein the initiating the first intent for the location request comprises: initiating the first intent for the location request based on a time elapsed from a previous initiation of an intent for the location request. ### Claim 3 (depends on 1) The device of claim 1, wherein the initiating the first intent for the location request comprises: initiating the first intent for the location request based on a type of the movement of the user. ### Claim 4 (depends on 3) The device of claim 3, wherein the initiating the first intent for the location request comprises: initiating the first intent for the location request based on the movement of the user being a fast movement type while the device is located within a user stay area. ### Claim 5 (depends on 3) The device of claim 3, wherein the initiating the first intent for the location request comprises: initiating the first intent for the location request based on the movement of the user being a slow movement type or a still type while the device is not located within a user stay area. ### Claim 6 (depends on 1) The device of claim 1, wherein the initiating the first intent for the location request comprises: initiating the first intent for the location request based on detection of a change in a cellular identification (Cell-ID) of the device. ### Claim 7 (depends on 1) The device of claim 1, wherein the initiating the first intent for the location request comprises: initiating the first intent for the location request in response to the device exiting a user stay area or entering a new user stay area. ### Claim 8 (depends on 1) The device of claim 1, wherein the requesting the current location of the device comprises: selecting a source for collecting information of the current location of the device; and collecting the information of the current location of the device using the source. ### Claim 9 (depends on 1) The device of claim 1, wherein the requesting the current location of the device comprises: determining that the device is connected to an active network location provider; and collecting the current location of the device using the active network location provider upon determining that an accuracy of location information provided by the active network location provider exceeds an accuracy threshold. ### Claim 10 (depends on 1) The device of claim 1, wherein the requesting the current location of the device comprises: collecting the current location of the device using global positioning satellite signals. ### Claim 11 (depends on 1) The device of claim 1, wherein the initiating the first intent is performed locally within the device. ### Claim 12 A computer-implemented method comprising: passively collecting, with one or more processors of a device, location information of the device based on one or more requests from a third party application or service on the device; initiating, with the one or more processors, a first intent for a location request requesting a current location of the device, based on a first measured movement in a first period of time exceeding a threshold; determining, with the one or more processors, a second measured movement in a second period of time after the initiating; determining, with the one or more processors, based on the second measured movement being less than the threshold, that a duration of time between a previous collection of location information of the device and the initiation of the first intent for the location request exceeds a first time threshold; and based on the determining that the duration of time exceeds the first time threshold, requesting the current location of the device. ### Claim 13 (depends on 12) The computer-implemented method of claim 12, wherein the initiating the first intent for the location request comprises: initiating the first intent for the location request based on a time elapsed from a previous initiation of an intent for the location request. ### Claim 14 (depends on 12) The computer-implemented method of claim 12, wherein the initiating the first intent for the location request comprises: initiating the first intent for the location request based on a type of movement of a user of the device. ### Claim 15 (depends on 14) The computer-implemented method of claim 14, wherein the initiating the first intent for the location request comprises: initiating the first intent for the location request based on the movement of the user being a fast movement type while the device is located within a user stay area. ### Claim 16 (depends on 14) The computer-implemented method of claim 14, wherein the initiating the first intent for the location request comprises: initiating the first intent for the location request based on the movement of the user being a slow movement type or a still type while the device is not located within a user stay area. ### Claim 17 (depends on 12) The computer-implemented method of claim 12, wherein the initiating the first intent for the location request comprises: initiating the first intent for the location request based on detection of a change in a cellular identification (Cell-ID) of the device. ### Claim 18 (depends on 12) The computer-implemented method of claim 12, wherein the initiating the first intent for the location request comprises: initiating the first intent for the location request in response to the device exiting a user stay area or entering a new user stay area. ### Claim 19 (depends on 12) The computer-implemented method of claim 12, wherein the requesting the current location of the device comprises: selecting a source for collecting information of the current location of the device; and collecting the information of the current location of the device using the source.
