Abstract
An emergency call practice application can execute on user equipment (UE) to allow users to practice dialing 9-1-1 or other emergency numbers. In a network practice mode, the emergency call practice application can initiate a practice emergency call by sending a call setup message to an IP Multimedia Subsystem (IMS). The IMS can route the call setup message to a Public Safety Answering Point (PSAP) routing server, which can recognize a destination identifier in the call setup message as being associated with a test server instead of a PSAP. The PSAP routing server can forward the call setup message to the test server to connect the practice emergency call.
Claims17
A method comprising:
- receiving, by a telecommunication network, a call setup message from a user equipment (UE) that includes a destination identifier of a test server of the telecommunication network that is associated with an emergency number, the destination identifier being different from identifiers of public safety answering points (PSAPs) associated with the emergency number;
- routing, by the telecommunication network, the call setup message to a PSAP routing server;
- receiving, by the test server, the call setup message from the PSAP routing server;
- and
- sending, by the test server, a response message to the UE based on receiving the call setup message,
- wherein the telecommunication network receives the call setup message at an IP Multimedia Subsystem (IMS) of the telecommunication network and forwards the call setup message to the PSAP routing server based on a service identifier included in the call setup message that identifies emergency services.
A telecommunication network, comprising:
- one or more network nodes, including a test server, having one or more processors and memory storing computer-executable instructions that, when executed by the one or more processors, cause the one or more network nodes to perform operations including:
- receiving a call setup message from a user equipment (UE) that includes a destination identifier of the test server that is associated with an emergency number, the destination identifier being different from identifiers of public safety answering points (PSAPs) associated with the emergency number;
- routing the call setup message to a PSAP routing server;
- receiving, by the test server, the call setup message from the PSAP routing server;
- sending, by the test server, a response message to the UE based on receiving the call setup message;
- connecting a practice emergency call between the UE and the test server based on the response message;
- and
- providing user feedback from the test server to the UE via the practice emergency call.
One or more non-transitory computer-readable media storing computer-executable instructions that, when executed by one or more network nodes of a telecommunication network, cause the one or more network nodes to perform operations comprising:
- receiving a call setup message from a user equipment (UE) that includes a destination identifier of a test server that is associated with an emergency number, the destination identifier being different from identifiers of public safety answering points (PSAPs) associated with the emergency number;
- routing the call setup message to a PSAP routing server;
- receiving, by the test server, the call setup message from the PSAP routing server;
- sending, by the test server, a response message to the UE based on receiving the call setup message;
- connecting a practice emergency call between the UE and the test server based on the response message;
- and
- providing user feedback from the test server to the UE via the practice emergency call.
