Abstract

The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. The method for processing a request for an emergency call comprises performing at least one of ignoring a reject cause received from a network, and providing highest priority to the emergency call in a call priority order defined for the UE after receiving the request for the emergency call.

Claims

1. A method for processing a request for an emergency call in an user equipment (UE), the method comprising:

performing, by a communication protocol layer (CP) of the UE, at least one of ignoring a reject cause received from a network;

providing a highest priority to the emergency call in a call priority order defined for the UE after receiving the request for the emergency call; and

continuing procedures for the emergency call to process the request.

2. The method as claimed in claim 1, wherein ignoring the reject cause comprises aborting procedures associated with handling of the reject cause.

3. The method as claimed in claim 1, wherein providing highest priority to the emergency call comprises stopping a timer initiated by the UE during a wait network command state of the UE while performing procedures corresponding to a mobile terminated (MT) call.

4. The method as claimed in claim 3, wherein the timer includes a T3240 timer.

5. The method as claimed in claim 1, wherein the call priority order, in descending priority order, comprises the emergency call, a high priority access, the MT call, and a mobile originated (MO) call.

6. The method as claimed in claim 1, wherein the emergency call is blocked until a tracking area update (TAU) procedure is completed.

7. The method as claimed in claim 1, wherein the reject cause includes a tracking area update (TAU) reject cause.

8. A user equipment (UE) for processing a request for an emergency call, wherein the UE comprises:

an integrated circuit further comprising at least one processor;

at least one memory having a computer program code within the circuit;

the at least one memory and the computer program code with the at least one processor cause a control plane (CP) of the UE to;

perform at least one of ignoring a reject cause received from a network, and providing highest priority to the emergency call in a call priority order defined for the UE after receiving the request for the emergency call; and

continue procedures for the emergency call to process the request.

9. The UE as claimed in claim 8, wherein the CP is configured to ignore the reject cause by aborting procedures associated with handling of the reject cause.

10. The UE as claimed in claim 8, wherein the CP is configured to provide highest priority to the emergency call by stopping a timer initiated by the UE during a wait network command state of the UE while performing procedures corresponding to a mobile terminated (MT) call.

11. The UE as claimed in claim 10, wherein the timer includes a T3240 timer.

12. The UE as claimed in claim 8, wherein the call priority order, in descending priority order, comprises the emergency call, a high priority access, the MT call, and a mobile originated (MO) call.

13. The UE as claimed in claim 8, wherein the emergency call is blocked until a tracking area update (TAU) procedure is completed.

14. The UE as claimed in claim 8, wherein the reject cause includes a tracking area update (TAU) reject cause.
