4.4Activate lpf Service via Website after Loss (Pri: Hi)

This use case enables the Owner to activate the LPF application to put her phone in “Lost Phone” mode.

1. Owner navigates to the LPF Website (if not already there.)

2. Owner logs-in using the Carrier’s Single-Sign-On (SSO) UI (if not already logged in.)

3. LPF Website recognizes and greets Owner as subscriber. If Owner has more than one phone subscribed to the LPF service, a mechanism is provided to activate the service for one phone.

4. The LPF “Help Me Find My Phone” screen appears. The Owner’s options here include:

   1. Lock and Locate My Phone

   2. Ring My Phone

   3. Locate My Phone – Available only if the phone was previously locked. Otherwise, this option is grayed out.

   4. Erase My Phone’s Personal Data

5. Owner selects “Lock and Locate My Phone”.

6. LPF Website asks Owner to specify:

   1. A phone number (different from the lost phone’s number!) at which a Finder can speak to or leave a message for the Owner.

   2. A 4-digit PIN that the Owner will use later to unlock the recovered phone.

7. Owner enters the requested data and confirms her request to Lock and Locate the phone.

8. LPF Server sends a “Lock and Locate” message to the LPF Handset App.

9. If the LPF Server successfully contacts and activates the LPF Handset App, then:

   1. The Website displays a progress indication stating that the phone is turned on, being locked, ringing, and being located.

   2. The Website displays on a panable/zoomable hybrid (aerial + roadway) map the phone’s:

      1. GPS location with uncertainty halo,

      2. Name of nearest street address or smallest enclosing polygon.

      3. Speed

      4. Direction (North, South, Northwest, etc.)

      5. Battery Charge Status

10. If the LPF Server detects that the phone is turned off or out-of-coverage (e.g. by using the SMSC “transaction mode” interface, as is done with Chaperone,) then:

    1. The user gets immediate feedback that the phone will be locked and located the next time it is powered on.

    2. If available, the LPF Server displays a cached a recent phone location (i.e. a location sent when the handset battery reached a preset low threshold.) The cached location is displayed just as the live location, except that it is clearly labeled as “Last Known Location” with the time at which the location was measured and reported.

11. The Website re-displays the “Help Me Find My Phone” options (without hiding or losing the map.) At this point, the “Lock and Locate My Phone” option is grayed out, and the “Ring My Phone”, “Locate My Phone”, and other options are enabled as appropriate.

4.5Enter the lpf Website after Previously Activating Service (Pri: Hi)

The Owner may come back to the LPF Website after previously activating the Lost Phone application in the course of seeking the phone. Her objective may be to ring the phone again, to locate it again, to erase the personal data, etc.

1. Owner navigates to the LPF Website (if not already there.)

2. Owner logs-in using the Carrier’s Single-Sign-On (SSO) UI (if not already logged in.)

3. LPF Website recognizes and greets Owner as subscriber. Any currently “Lost” phones are highlighted on the welcome screen. If Owner has more than one lost phone subscribed to the LPF service, a mechanism is provided to select the one “Lost” phone.

4. The LPF “Help Me Find My Phone” screen appear, including a map showing the last known phone location. The Owner’s menu options here include:

   1. Lock and Locate My Phone – Grayed out.

   2. Ring My Phone

   3. Locate My Phone

   4. Erase My Phone’s Personal Data
