Claim:
1. A method of conveying location information representing a physical location, the method comprising: acquiring by a first communication device a first location information and a second location information, the second location information being acquired subsequently to the acquiring of the first location information, the first communication device being an endpoint device having a processor and non-transitory memory; setting a time interval between acquiring the first location information and the second location information or a condition resulting in the change of the physical location of the first communication device by at least one location update trigger parameter of a location conveyance policy used by the first communication device, wherein the location update trigger parameter is selected from the group consisting of: detecting by the first communication device a deviation of the second location information from the first location information representing a change of the physical location of the first communication device, and, triggered by the detected change of the physical location of the first communication device, the first communication device sending a first signaling message to a second communication device, the first signaling message comprising at least one of information identifying the deviation of the second location information from the first location information and information identifying the second location; triggered by the second communication device receiving the first signaling message, querying a mapping server by the second communication device to obtain routing information with respect to the second location information conveyed to the second communication device and to validate the second location information; and storing the queried routing information and validated second location information in non-transitory memory of the second communication device for use in routing of communications and/or providing location information in connection with communications involving the first communication device.
