Abstract
A code generator can receive a data object from a legacy network gateway location interwork function (LNG-LIF) for an emergency services call initiated by an end-user device, wherein the data object includes location information in a legacy format. The code generator can select fields of the location information for the emergency services call. The code generator can convert data object in the legacy format into a presence information data format location object (PIDF-LO) based on the selected fields of the location information in the data object for the emergency services call. The PIDF-LO embeds location information for the end-user device. Additionally, the code generator can send the PIDF-LO to the LNG-LIF, wherein the PIDF-LO is a format consumable by an Emergency Call Routing Function (ECRF).
