Abstract

Described is a Logical Network Controller (LNC) operable to communicate with a User Equipment (UE) on a wireless network. The LNC may be operable to process connection request transmissions from the UE requesting a connection with an application service, such as a Mission-Critical Internet-of-Things (MC-IoT) service, to determine a Connection-specific Application Server Instance (CASI) for the application service, and to generate connection response transmissions for the UE carrying a connection-specific source IP address corresponding to the UE and a connection-specific destination IP address corresponding to the CASI. The UE may be operable to generate connection request transmissions for the LNC requesting a connection with an application service, to process connection response transmissions from the LNC carrying a connection-specific destination IP address corresponding to a CASI for the application service, and to generate connection-specific transmissions for the CASI, the connection-specific transmissions carrying the connection-specific destination IP address.
