Message Transmission between Core Network Domains

Abstract:

Network equipment (300) is configured as a proxy (40, 50) for one of multiple different core network domains of a wireless communication system (10). The network equipment (300, 400) is configured to receive a message (60) that has been, or is to be, transmitted between the different core network domains. The network equipment (300, 400) is further configured to perform inter-domain security measures according to a security policy (80). The security policy (80) may indicate which one or more portions of (e.g., the content of a field in) the message (60) are to be used by inter-domain security measures (e.g., inter-domain anti-spoofing measures) and/or which types of messages are to be used by the inter-domain security measures.
