    Abstract: In a communication system, a translation server individually associates session control servers with transfer control servers. One of the session control servers receives a registration for a User Equipment (UE) over a first network. The translation server associates the UE with the session control server in the data structure. The session control server exchanges first control signaling with the UE to establish a media session over the first network. The translation server receives a session transfer request for the UE from a second network. The translation server processes the data structure to identify the transfer control server that is associated with the session control server that is associated with the UE. The translation server transfers the session transfer request to the transfer control server. The transfer control server exchanges second control signaling with the second network to transfer the media session from the first network to the second network.

    Abstract: A wireless access node transmits an available Public Land Mobile Network Identifier (PLMN ID) associated with available wireless channels to a wireless device. The wireless access node receives the available PLMN ID from the wireless device and responsively exchanges signals with the wireless device over the available wireless channels. The wireless access node identifies a transition condition for the wireless communication device and responsively transfers a Physical Cell Identifier (PCI) and a hidden PLMN ID to the wireless communication device. The hidden PLMN ID is associated with hidden wireless channels. The wireless access node receives the PCI and the hidden PLMN ID from the wireless communication device and responsively exchanges signals with the wireless communication device over the hidden wireless channels.

    Abstract: A Fifth Generation Core (5GC) Long Term Evolution (LTE) network authenticates a wireless User Equipment (UE) for LTE data service using a 5GC Subscriber Concealed Identifier (SUCI). A Mobility Management Entity (MME) receives the 5GC SUCI and transfers the 5GC SUCI to a 5GC authentication system. The 5GC authentication system determines a 5GC Subscriber Permanent Identifier (SUPI) and authentication vector based on the 5GC SUCI. The 5GC authentication system transfers the 5GC SUPI and the 5GC authentication vector to the MME. The MME exchanges 5GC authentication data with the UE. The MME authenticates the UE based on the 5GC authentication vector and the 5GC authentication data. In response to the 5GC authentication, the MME initiates the LTE data service for the UE based on the 5GC SUPI.
