Abstract
This memo describes paging, assesses the need for IP paging, and
presents a list of recommendations for Seamoby charter items
regarding work on paging. The results are specifically directed
toward the task undertaken by the design team, and are not meant to
be the definitive word on paging for all time, nor to be binding on
Seamoby or other working groups, should the situation with regard to
IP mobility protocols or radio link support undergo a major change.
1.0 Introduction
The IESG has requested that the Seamoby Working Group develop a
problem statement about the need for additional protocol work to
support alerting of dormant mode mobile hosts, commonly known as IP
paging, for seamless IP mobility. The paging design team interpreted
this as direction to examine whether location of a mobile node in
power saving mode can be supported by the existing Mobile IPv4 and
Mobile IPv6 protocols given existing radio link protocols.
Many existing radio link protocols and mobile systems support
location of and radio link establishment with mobile nodes that are
in power saving mode and hence are not actively listening for
delivery of IP packets all the time or are not listening on the radio
channels normally associated with delivering IP traffic to mobile
nodes. This alerting functionality allows mobile nodes to reduce
power consumption and decreases signaling load on the network for
tracking mobiles that are not actively participating in IP packet
generation or reception.
