Analysis of Port Control P0rotocol in Mobile Network
draft-chen-pcp-mobile-deployment-03
Abstract
This memo provides a motivation description for the Port Control
Protocol (PCP) deployment in a 3GPP mobile network environment. The
document focuses on a mobile network specific issues (e.g. cell
phone battery power consumption, keep-alive traffic reduction), PCP
applicability to these issues is further studied and analyzed.

1. Introduction
The Port Control Protocol[I-D.ietf-pcp-base] allows an IPv6 or IPv4
host to control how incoming IPv6 or IPv4 packets are translated and
forwarded by a network address translator (NAT) or simple
firewall(FW), and also allows a host to optimize its outgoing NAT
keepalive messages. A 3rd Generation Partnership Project (3GPP)
network can benefit from the use of the PCP service. Traffic in a
mobile network is becoming a complex mix of various protocols,
different applications and user behaviors. Mobile networks are
