DiMoWiNe 2011 - Distributed Mobility Management in Future Wireless Networks (DiMoWiNe)

Distributed Mobility Management in Future Wireless Networks (DiMoWiNe)

The 3GPP Evolved Packet System (EPS) is gaining ground as the new wireless broadband technology. EPS defines both the evolved radio access, known as Evolved UTRAN, and the IP core network known as Evolved Packet Core (EPC). EPC provides the necessary tools and system level support for IP mobility management in a heterogeneous networking environment with high degree of standardized machinery for billing, policy control, inter-provider roaming, subscriber and service management. There is also increasing interest of using 3GPP architectures for emerging machine-to-machine and vehicular communication solutions.

The 3GPP EPS claims to be a flat architecture, and this is true to some extent from the radio access network point of view. However, at the IP level all traffic is still anchored to centralized gateway functions, which may mitigate possible benefits of the otherwise flat design of the radio access network. Furthermore, it is not uncommon to virtualize the transmission network between the radio access and operator core network into a large aggregated layer-2 domain, which again impacts negatively the natural routing of IP packets.

Recently, the exponential growth of traffic volume has inspired research on the evolution of the EPC architecture towards more distributed mobility anchoring and truly IP flat architectures. Distributed mobility management and flat architectures aim at lowering the traffic load on centralized gateway functions and at better distributing the IP traffic across the operator’s networks. These enhancements target an enhanced system wide scalability in a long run. In a flat architecture design the use of local IP services without system provided IP level mobility support is a promising approach to lower the need for mobility tunnelling and thus reducing the excessive signalling load caused by frequent mobility and tunnelling management related control signalling.

Distributed mobility management and IP flat architecture design with local IP connectivity is supposed to work for current low velocity and mostly stationary use of IP access services. However, distributed mobility management and flat architecture design of the 3GPP EPC evolution is challenged by increasing number of mobility events when radio cell size shrinks and inter-access technology handovers become frequent due the trend of compounding licensed radio access coverage with cheaper short range radio access technologies. There are obvious tradeoffs such as increased signalling load for IP mobility and mobility tunnel management on the core network side, and possible rapidly changing IP addressing in case of local IP access. Both procedures have a negative impact on the overall IP access experience and reliability.

The workshop promotes solutions that combine both future distributed mobility management and IP flat architecture goals with high degree of mobility events due objects with high velocity. The workshop scope includes but is not limited to topics on:

Distributed mobility management and flat architectures,
Combination of anchored IP mobility with local IP access,
Signalling traffic reduction during handovers,
IP mobility without anchored tunnelling solutions,
IP address/prefix selection and configuration solutions when IP addresses/prefixes change frequently,
Network Mobility in vehicular systems,
Vehicular IP communication based on 3GPP EPS,
Car-to-car communication,
LTE-in-trains solutions.

This one-day workshop aims to provide the participants with a comprehensive and thorough vision of high velocity mobility in future distributed mobility and flat architecture evolved from 3GPP EPC. Starting from existing solutions the workshop solicits researchers from the industry and the academia to submit original and high quality papers. The workshop will give higher priority to experimental papers describing early implementations and functional systems addressing the tradeoffs above mentioned.
