name: IP
full_form: Internet Protocol
context: This solution is for the key issue 2.7 on EEC provided IP address verification. The EEC can spoof the IP address because the source IP address (i.e. UE private IP address) of the message is concealed by UPF via NAT, the EES only know the public IP address which can be used by different UEs. In NAT case, to differentiate different UEs using the same public IP address, the UPF will allocate a unique port number for each UE and the UPF stores the mapping between private IP address, public IP address and port number, the IP information knowed in each node in NAT case is showed in the following figure 6.30.1-1. Figure 6.30.1-1: NAT procedure Therefore, to verify the EEC provided IP address, this solution proposes to use the mapping between private IP address, public IP address and port number in the UPF to verify the mapping EEC provided IP address, EES obtained public IP address and port number based on the source IP address and port number of received UE ID API message.
description: Internet Protocol (IP) is a fundamental protocol in the internet protocol suite that provides logical addressing and routing for data transmission over networks. It enables devices to communicate by assigning a unique address to each device.
explanation: The text describes IP as a protocol responsible for addressing and routing data packets, which aligns with the definition of a protocol as a set of rules governing communication between entities.
