Abstract: Methods and techniques are described for supporting different location solutions in a wireless network (e.g. a 5G network) in which two different location solutions coexist in the same wireless network, and where a network operator may migrate network support from one location solution to the other. For location support of emergency calls, handover of an emergency call can be supported from a network node (e.g. an AMF) that supports one location solution to a network node (e.g. another AMF) that supports the other location solution. The handover may be supported by transferring indications of the handover between network nodes (e.g. including a GMLC, AMF and/or an LMF) to enable reconfiguration of location support for the emergency call at an LRF and GMLC from one location solution to the other.

Abstract: A route tracing request packet is generated comprising a time-to-live value, a source address of a source of the route tracing request packet, and an address of a destination of the route tracing request packet. The source and destination are in the virtual network; the route tracing request packet is usable to identify the virtual appliance, and the virtual appliance is configured to examine the route tracing request packet for a time-to-live value indicating that the route tracing request packet has expired and sending a time-to-live exceeded message to the source address. The time-to-live exceeded message comprises an identifier for the virtual appliance. The route tracing request packet is forwarded to the destination. The time-to-live exceeded message is received. Data is extracted to determine network virtual appliances that were traversed by the route tracing request packet prior to expiration of the time-to-live. The network virtual appliances are reported.

Configuration is done using high-level communication after authenticating the identity of the RTU and the integrity of the configuration request.
