Embodiment Construction

[0014] Illustrative embodiments of the invention are described below. In the interest of clarity, not all features of an actual implementation are described in this specification. It should be understood that in developing any such actual embodiment, many implementation-specific decisions may be made to achieve developer-specific goals that may vary from one implementation to another, such as adhering to system-dependent and industry-dependent constraints. Furthermore, it should be appreciated that such planning of development might be complex and time consuming, but would nevertheless be a routine undertaking for those of ordinary skill in the art having the benefit of this disclosure.

[0015] The present invention relates to an innovative method for locating emergency callers and utilizing location information to route emergency calls to appropriate Public Safety Answering Points (PSAPs). In addition, location information is also used to provide callback capabilities from...

Abstract

The present invention relates to methods and apparatus for emergency call routing using end nodes. A method of routing an emergency call includes receiving an emergency call, and identifying an end node associated with the call. An end node may be a communication device involved in establishing an emergency call that is geographically close to the originator of said emergency call. A lookup table is then accessed to identify the appropriate Public Safety Answering Point (PSAP) associated with the end node, and the emergency call is routed to the identified PSAP.

Description

technical field [0001] The present invention relates generally to the field of telecommunications, and more particularly to wireless communications. Background technique [0002] In the field of wireless telecommunications, such as cellular telephony, a system typically includes a number of base stations distributed over the area served by the system. Various users within the area, fixed or mobile, may access the system and thus other interconnected telecommunication systems via wireless links with one or more base stations. Typically, as the user moves, the mobile device remains in communication with the system as it passes through the area by communicating with one base station after another. A mobile device may communicate with the closest base station, the base station with the strongest signal, the base station with sufficient capacity to accept communications, and so on. [0003] Typically, voice and data can be transmitted over a wireless link using two basic switch...
