Bypassing enhanced services

Abstract

A communication environment includes of one or more subscriber terminals capable of initiating emergency voice calls over a telephony network. The subscriber terminal further send messages over either a data network or a telephony signaling network to a communication management system. The communication management system receives messages from a subscriber terminal, either via a data network or a telephony signaling network. It also consists of one or more telephony switching nodes capable of querying the emergency context node for a called party emergency context. It also consists of one or more servers that provide advanced call control services.

What is claimed is: 
     
         1 . A computer-implemented method, comprising:
 receiving a first context message identifying a first context state of a mobile device, wherein the first context state is one of a plurality of defined potential context states, each of the plurality of defined potential context states corresponding to a range of potential sensor information regarding an environment of the mobile device, and wherein an availability of the mobile device to establish communication is defined as a function of a previously received context state of the mobile device, independent of specific sensor information on which the previously received context state is based;   independent of processing the specific sensor information on which the first context state is based, processing the first context state to determine that the availability of the mobile device corresponds to providing enhanced communication services to the mobile device, wherein the enhanced communication services disallow at least one request for communication including the mobile device;   receiving a second context message identifying a second context state of the mobile device, wherein the second context state is one of the plurality of defined potential context states;   independent of processing the specific sensor information on which the second context state is based, processing the second context state to determine that the updated availability of the mobile device corresponds to bypassing the enhanced communication services to the mobile device;   receiving the at least one request for communication including the mobile device; and   allowing the least one request for communication including the mobile device in accordance with a bypass of the enhanced communication services to the mobile device.
