Type:
According to the IP paging message type.
To be specified. Type codes used in this project:
DORMANT MODE REQUEST 152
DORMANT MODE REPLY 153
PAGING REQUEST 154
Code:
Checksum:
Sequence Number:
Set to 0 for all messages as described here for IP paging.
Calculated according to the ICMPv6 standard.
Allows for correlating replies with requests.
Flags: R: Reserved. To be initialised with 0.
I: Implicit dormant registration (1=Implicit registration).
U: Updating messages (1=Updating message).
Reserved:
Status Code:
Options:
Reserved for future use.
Result of a request message.
Currently specified 0x00 SUCCESS
0x02 USE EXPLICIT REGISTRATION
0xff ERROR
One or more TLV-encoded option. Format as described below, usage
according to the paging concept.
Most of the signalling message details are encoded as option, which allows carrying one or more options
with the message when needed. Options are encoded as generic TLV messages, as illustrated in the
following figure.

Value
Type: Option type identifier according to the table below.
Length: Option length in octets, including the Type and the Length field.
The following options will be implemented within the framework of the Moby Dick project. These do not
include the security related options and some technology specific address options when not needed in the
project’s testbed (e.g. International Mobile Subscriber Identifier – IMSI). The options referred to in the
following table are required to be implemented to support basic protocol operation according to the IP
paging scheme.
Option Value-Length Type
IPv6 Home Address 16 0x01
IPv6 Care-of Address 16 0x02
IPv6 PA address 16 0x03
Common Paging ID Variable 0x04
Paging Area ID 4 0x05
Registration Lifetime 16 0x06
Home Agent Address 16 0x07

An overview on the format of the Common Paging Identifier can be found below.
For IP paging, a common identifier is used. Its structure allows ARs to derive information, which is
necessary to build the appropriate Solicited Node Multicast address for an individual mobile terminal on
the respective technology. The identifier has the 24bit-identifier part of the MAC address for IEEE 802.3
and IEEE 802.11b included, for TD-CDMA the 24bit terminal identifier part of the International Mobile
station Equipment Identity (IMEI) will be taken. To allow flexible deployment of the common identifier,
