RADIO ACCESS NETWORK SHARING USING A TRANSPORT PROXY FUNCTION

Methods, systems, and devices for wireless communications are described. An access and mobility management function (AMF) proxy may establish a first communication link between a radio access network (RAN) of a first network operator and a first AMF of the first network operator via the AMF proxy and a second communication link between the RAN of the first network operator and a second AMF of a second network operator via the AMF proxy. The AMF proxy may receive a message from the RAN via the first communication link or the second communication link directed towards a target proxy endpoint address of the first AMF or of the second AMF. As such, the AMF proxy may transmit the message from the RAN to the first or to the second AMF based on a mapping between a set of target proxy endpoint addresses, and one or more source proxy endpoint addresses.
