Location of a mobile handset is facilitated. A system includes three or more location measurement units that each correspond to a sector of the cell site. The location measurement units transmit location related information to a computation component. The computation component receives the location related information and performs a triangulation calculation on the information to define the location of the mobile handset. 1. A method , comprising:receiving, by a system comprising a processor, a first time delay signal from a first location measurement device, a second time delay signal from a second location measurement device, a third time delay signal from a third location measurement device, and a fourth time delay signal from a fourth location measurement device, wherein the first location measurement device, the second location measurement device, the third location measurement device and the fourth location measurement device are associated with respective different sectors of a cell site and the first time delay signal, the second time delay signal, the third time delay signal and the fourth time delay signal relate to a position of a mobile handset;from a determined three time delay signals of the first time delay signal, second time delay signal, third time delay signal, and the fourth time delay signal, composing, by the system, a time delay signal that comprises information to facilitate triangulating the position of the mobile handset; andbased on the time delay signal, triangulating, by the system, the position of the mobile handset.2. The method of claim 1 , wherein the first time delay signal claim 1 , the second time delay signal claim 1 , the third time delay signal claim 1 , and the fourth time delay signal comprise time difference of arrival information.3. The method of claim 2 , wherein the time difference of arrival information is represented according to an enhanced observed time difference of arrival standard.4. The method of claim 1 , wherein ...
