Methods and apparatus for communicating location information for enhancing emergency positioning
First Claim
1. A method in a first node in a communication network of handling positioning information, comprising:
- obtaining positioning information from a second node in the communication network;
transforming the positioning information into at least one of a graphical format and a text-encoded graphical format; and
sending a message including the transformed positioning information to a third node in the communication network, wherein the transformed positioning information includes position uncertainty information.

Abstract
Methods and apparatus for handling positioning information by sending a positioning result, which can include uncertainty information, in at least one of a graphical format and a text-encoded graphical format. Positioning result accuracy, which can be important for emergency services, is improved by avoiding conversion between positioning result formats. Positioning results can be flexibly delivered, without concern for the particular radio access technology used in a communication network. The graphical format can be a vector graphics format, such as Scalable Vector Graphics and Wireless Vector Graphics. The text-encoded graphical format can be based on the extensible Markup Language, the positioning information in the graphical and/or text-encoded graphical format can be signaled by a messaging service.
