Claim 14:
15. A non-transitory computer-readable medium storing a set of instructions, the set of instructions comprising:
one or more instructions that, when executed by one or more processors of a network device, cause the network device to:
receive, for an emergency call, a session initiation protocol (SIP) invite that includes:
a registered address of a user device that initiated the emergency call, and
network slice selection assistance information (NSSAI);

determine, based on extracting the NSSAI from the SIP invite, that the NSSAI uniquely identifies a low latency and time-sensitive network (TSN) slice of a private network;
determine, based on the NSSAI uniquely identifying the low latency and TSN slice of the private network, that the user device is associated with the private network;
extract the registered address of the user device from the SIP invite and based on the user device being associated with the private network; and
provide the registered address to another network device configured to determine a registered geographic location of the user device, based on the registered address, and to provide the registered geographic location to a public safety answering point associated with the emergency call.
