Abstract
A method includes initiating an emergency call, responsive to the initiating step, generating a trigger, wherein the trigger comprises a request to suspend a call restriction associated with a user device, and transmitting the trigger using a Ut interface to a server to suspend the call restriction.
Claims12
A method comprising:
- Initiating an emergency call using a network having an Internet Protocol Multimedia Subsystem (IMS);
- Responsive to the initiating step, generating a trigger, wherein the trigger comprises a request to suspend a call restriction associated with a user device;
- and Transmitting the trigger using a Ut interface from a user device to an application server to suspend the call restriction;
- receiving a response from the application server wherein the response comprises a time period;
- wherein the call restriction is enabled at the end of the time period.

An apparatus comprising:
- an input/output system for communicatively coupling the apparatus to an input device;
- a processor communicatively coupled to the input/output system;
- and
- a memory storing instructions that cause the processor to effectuate operations when executed, the operations comprising:
- Initiating an emergency call using a network having an Internet Protocol Multimedia Subsystem (IMS);
- Responsive to the initiating step, generating a trigger, wherein the trigger comprises a request to suspend a call restriction associated with a user device;
- Transmitting the trigger using a Ut interface from a user device to an application server to suspend the call restriction;
- wherein the operations further comprise receiving a response from the application server wherein the response comprises a time period;
- wherein the call restriction is enabled at the end of the time period.
6 more elements
A method comprising:
- Receiving, by an application server, a message from a user device over a Ut interface in a network having an Internet Protocol Multimedia Subsystem (IMS) wherein the message comprises a trigger;
- Responsive to the receiving step, causing a call restriction to be disabled;
- Sending a response message to the user device wherein the response message comprises a time period;
- and
- Re-enabling the call restriction at the conclusion of the time period.
