Abstract
Solutions for testing emergency call handling capability include: receiving, into a user equipment (UE), a dialed number (e.g., '922'); mapping, by the UE, the dialed number to a test service uniform resource name (URN); and transmitting the test service URN to a wireless network. Further solutions include: receiving, by the wireless network, from the UE, the test service URN; differentiating, by the wireless network, the test service URN from an SOS URN; and based on at least receiving the test service URN, establishing an emergency test voice call between the UE and a public safety answering point (PSAP) emulator. In some examples, the test service URN comprises “urn:service” and “test” (e.g., “urn:service:test.sos” or “urn:service:sos.test”), and is flagged by a bit field of an emergency service category value. In some examples, the wireless network transmits to the UE, an indication that the dialed number maps to the test service URN.
