Key Properties of Proxy Mobile IPv6 Technology
- Based on Open Internet Standards
- No client software requirement
- IP Address Continuity
- Session Continuity when roaming within a single access technology domain
- The mobile node can be an IPv4-client, IPv6 client or a dual stack client
- The transport network between LMA (Local Mobility Anchor) and MAG (Mobile Access Gateway) can be IPv4 or IPv6
- The tunnel between the LMA and MAG is a shared tunnel
- The tunnel between LMA and MAG can be based on GRE or IP-in-IP
- No packet fragmentation, as PMIP advertises adjusted MTU values on the access side
- Extremely Light Weight Protocol, MAG function can be implemented on a low-cost access point
- Minimal Handover Latency
- Signaling semantics are based on IPv6, but can be enabled on an IPv4 network
- PMIPv6 signaling can be protected using standard IPsec transport mode ESP
- Natural Support for Client Mobility. The LMA is a Mobile IPv6 Home Agent
- Protocol Interface supported in 3GPP LTE Architecture
- Standard Protocol Glue for linking access technology domains
- Industry Wide Participation in Standardization
- Adopted in 3GPP, WiMAX and 3GPP2 Architectures
- Central traffic aggregation for charging, policy enforcement, LI and DPI Enforcement
- Supported in all 3GPP LTE Packet Data Gateways (LMA function in PDN Gateway)
- Future proof

Famous quotes containing the words key, properties, mobile and/or technology:
“Woe unto you, lawyers! for ye have taken away the key of knowledge: ye entered not in yourselves, and them that were entering in ye hindered.”
—Bible: New Testament Jesus, in Luke 11:52.
“The reason why men enter into society, is the preservation of their property; and the end why they choose and authorize a legislative, is, that there may be laws made, and rules set, as guards and fences to the properties of all the members of the society: to limit the power, and moderate the dominion, of every part and member of the society.”
—John Locke (1632–1704)
“From three to six months, most babies have settled down enough to be fun but aren’t mobile enough to be getting into trouble. This is the time to pay some attention to your relationship again. Otherwise, you may spend the entire postpartum year thinking you married the wrong person and overlooking the obvious—that parenthood can create rough spots even in the smoothest marriage.”
—Anne Cassidy (20th century)
“Our technology forces us to live mythically, but we continue to think fragmentarily, and on single, separate planes.”
—Marshall McLuhan (1911–1980)
