Abstract:
Methods and apparatuses for reducing time to receive a call failure indication in a wireless communications system are provided. A request to initiate a call with a target user equipment (UE) is received from an originating UE. A call setup message that corresponds to the request is sent to a network node, and an internet control message protocol (ICMP) message indicative of the network node lacking a dedicated bearer to a radio access network that corresponds to the target UE can be received in response to the request. Based on the ICMP message, a status failure message is sent to the originating UE indicating failure of the call.
