The requirements below have been extracted from IETF RFCs 1981 [2], 2460 [5], 2461 [6], 2462 [7], 2463 [8],
2464 [9], 2675 [10], 3513[11]) and ETSI specifications TS 123 060 [12], TS 123 221 [13], TS 123 228 [14],
TS 129 061 [15]).
4.1 Requirements extracted from TS 123 060
RQ_000_7003 Configure Address
TS 123 060 9.2.1.1 MANDATORY
Applies to: Host
Context:
An IPv6 Mobile Station is performing either stateless or stateful address autoconfiguration
Requirement:
An IPv6 Mobile Station SHALL use the interface identifier provided by the Gateway GPRS Support
Node to configure its link-local address
Specification Text:
To ensure that the link-local address generated by the MS does not collide with the link-local
address of the GGSN, the GGSN shall provide an interface identifier (see RFC 2462 [69]) to the
MS and the MS shall use this interface identifier to configure its link-local address. This is
applicable for both stateful and stateless IPv6 address autoconfiguration. In case of stateless
address autoconfiguration however, the MS can choose any interface identifier to generate
addresses other than link-local, without involving the network. In particular, the SGSN and the
GGSN are not updated with the actual address used by the MS, as the prefix alone identifies the
PDP context.

7 ETSI TS 102 514 V2.1.1 (2008-02)
RQ_000_7004 Detect Duplicate Address (DAD)
TS 123 060 9.2.1.1 OPTIONAL
Applies to: Host
Context:
An IPv6 Mobile Station is performing stateless address autoconfiguration using a prefix
advertised by a Gateway BPRS Support Node in a PDP context.
Requirement:
The IPv6 Mobile Station MAY omit duplicate address detection.
Specification Text:
Because any prefix that the GGSN advertises in a PDP context is unique within the scope of the
prefix (i.e. site-local or global), there is no need for the MS to perform Duplicate Address
Detection for this IPv6 address. Therefore, the GGSN shall silently discard Neighbor
Solicitation messages that the MS may send to perform Duplicate Address Detection. It is
possible for the MS to perform Neighbor Unreachability Detection towards the GGSN, as defined
in RFC 2461[71]; therefore if the GGSN receives a Neighbor Solicitation as part of this
procedure, the GGSN shall provide a Neighbor Advertisement as described in RFC 2461.

RQ_000_7005 Detect Duplicate Address (DAD)
TS 123 060 9.2.1.1 MANDATORY
Applies to: Router
Context:
An IPv6 Mobile Station is performing stateless address autoconfiguration using a prefix
advertised by a Gateway BPRS Support Node in a PDP context.
Requirement:
The IPv6 Gateway GPRS Support NODE SHALL silently discard any Neighbor Solicitation messages
sent by the IPv6 Mobile Station.
Specification Text:
Because any prefix that the GGSN advertises in a PDP context is unique within the scope of the
prefix (i.e. site-local or global), there is no need for the MS to perform Duplicate Address
Detection for this IPv6 address. Therefore, the GGSN shall silently discard Neighbor
Solicitation messages that the MS may send to perform Duplicate Address Detection. .

RQ_000_7006 Stateless Autoconfiguration
TS 123 060 9.2.1.1 MANDATORY
Applies to: Router
Context:
An IPv6 Mobile Station has sent an "Activate PDP Context Request" to its Serving GPRS Support
Node
Requirement:
The IPv6 Gateway GPRS Support Node SHALL NOT advertise the same prefix on more than one PDP
context on a given APN or set of APNs, within the same addressing scope.
Specification Text:
The GGSN sends a Router Advertisement message. The Router Advertisement messages shall contain
the same prefix as the one provided in step 2. A given prefix shall not be advertised on more
than one PDP context on a given APN, or set of APNs, within the same addressing scope. The GGSN
shall be configured to advertise only one prefix per PDP context

After the MS has received the Router Advertisement message, it constructs its full IPv6 address
by concatenating the interface identifier received in step 3, or a locally generated interface
identifier, and the prefix received in the Router Advertisement. If the Router Advertisement
contains more than one prefix option, the MS shall only consider the first one and silently
discard the others.

RQ_000_7007 Stateless Autoconfiguration
TS 123 060 9.2.1.1 MANDATORY
Applies to: Host
Context:
An IPv6 Mobile Station receives a Router Advertisement message which contains more than one
prefix.
Requirement:
The IPv6 Mobile Station SHALL use the first prefix and silently discard the others.
Specification Text:
The GGSN sends a Router Advertisement message. The Router Advertisement messages shall contain
the same prefix as the one provided in step 2. A given prefix shall not be advertised on more
than one PDP context on a given APN, or set of APNs, within the same addressing scope. The GGSN
shall be configured to advertise only one prefix per PDP context

ETSI

---------------------- Page: 7 ----------------------
8 ETSI TS 102 514 V2.1.1 (2008-02)
After the MS has received the Router Advertisement message, it constructs its full IPv6 address
by concatenating the interface identifier received in step 3, or a locally generated interface
identifier, and the prefix received in the Router Advertisement. If the Router Advertisement
contains more than one prefix option, the MS shall only consider the first one and silently
discard the others.

RQ_000_7009 Startup Router Advertisement Behavior
TS 123 060 9.2.1.1 MANDATORY
Applies to: Router
Context:

Requirement:
An IPv6 Gateway GPRS Support Node shall automatically and periodically send Router
Advertisement messages towards the Mobile Station after a PDP context of type IPv6 is activated
Specification Text:
IPv6 stateful address autoconfiguration uses the standard External PDN Address Allocation
procedure, as described in TS 29.061. The GGSN informs the MS that it shall perform stateful
address autoconfiguration by means of the Router Advertisements, as defined in RFC 2461. For
this purpose, the GGSN shall automatically and periodically send Router Advertisement messages
towards the MS after a PDP context of type IPv6 is activated. The use of stateless or stateful
address autoconfiguration is configured per APN.

4.2 Requirements extracted from TS 123 221
RQ_000_7010 3GPP UE supports IPv6
TS 123 221 5.6 MANDATORY
Applies to: Host
Context:

Requirement:
A 3GPP User Equipment supporting IPv6 SHALL comply with the Basic IP group of specifications as
defined in RFC3316.
Specification Text:
The set of IPv6 functionality a 3GPP UE will require is dependent on the services (IMS, Packet
Streaming etc.) it will use.

As a minimum, a 3GPP UE shall comply with the Basic IP group of specifications as defined in
RFC3316. This IPv6 functionality is sufficient to provide compatibility towards IPv6 entities
external to 3GPP.

A 3GPP UE shall follow the recommendations for the IP Security set of functions in RFC3316
when a specific service requires such functions.

According to the procedures defined in TS 23.060, when a UE is assigned an IPv6 prefix, it can
change the global IPv6 address it is currently using via the mechanism defined in RFC 3041, or
similar means, without updating the PS domain. Any application that requires full IP address
knowledge shall provide a mechanism to get the latest IPv6 address when the IPv6 address in the
UE has been changed. An example of such means is defined in TS 23.228.

Note: RFC3316 does not make any recommendations on preferred transition and interoperability
    mechanisms between IPv4 and IPv6.

4.3 Requirements extracted from TS 129 061
RQ_000_7000 Configure Address
TS 129 061 11.2.1.3 MANDATORY
Applies to: Host
Context:
An IPv6 Mobile Station which is capable of both stateless and stateful autoconfiguration.
Requirement:
The IPv6 Mobile Station SHALL use stateless autoconfiguration to configure the address and
stateful autoconfiguration to configure additional parameters only.
Specification Text:
Stateful and Stateless Autoconfiguration may also co-exist. In that case, the MS shall use
Stateless to configure the address and Stateful to configure additional parameters only. The MS
shall not use Stateless and Stateful Address Autoconfiguration simultaneously since GPRS only
supports one prefix per PDP.

ETSI

9 ETSI TS 102 514 V2.1.1 (2008-02)
RQ_000_7001 Configure Address
TS 129 061 11.2.1.3 MANDATORY
Applies to: Host
Context:

Requirement:
An IPv6 Mobile Station SHALL NOT use both stateless and stateful autoconfiguration
simultaneously.
Specification Text:
Stateful and Stateless Autoconfiguration may also co-exist. In that case, the MS shall use
Stateless to configure the address and Stateful to configure additional parameters only. The MS
shall not use Stateless and Stateful Address Autoconfiguration simultaneously since GPRS only
supports one prefix per PDP Context

RQ_000_7002 Configure Address
TS 129 061 11.2.1.3 MANDATORY
Applies to: Host
Context:

Requirement:
An IPv6 Mobile Station SHALL support stateless address autoconfiguration.
Specification Text:
For MS, IPv6 Stateless Address Autoconfiguration is mandatory, and IPv6 Stateful Address
Autoconfiguration is optional.

RQ_000_7008 Startup Router Advertisement Behavior
TS 129 061 11.2.1.3.2 OPTIONAL
Applies to: Router
Context:

Requirement:
AN IPv6 Gateway GPRS Support Node MAY omit the randomisation of the period between sending
Router Advertisements.
Specification Text:
The handling of Router Advertisements shall be consistent with what is specified in RFC 2461
[44]. For the MS-GGSN link however, some specific handling shall apply. The randomisation part
to determine when Router Advertisements shall be sent may be omitted since the GGSN is the only
router on the link. Furthermore, some 3GPP specific protocol constants and default values shall
apply (see subclause "IPv6 Router Configuration Variables in the GGSN"). These relate to the
periodicity of the Router Advertisements initially and during continued operation. The
motivation for this is to have a faster user-plane set-up even in bad radio conditions and to
minimize MS power consumption during long continued operation.

RQ_000_7011 Configure Address
TS 129 061 11.2.1.3 OPTIONAL
Applies to: Host
Context:

Requirement:
An IPv6 Mobile Station MAY support stateful address autoconfiguration.
Specification Text:
For MS, IPv6 Stateless Address Autoconfiguration is mandatory, and IPv6 Stateful Address
Autoconfiguration is optional.

RQ_000_7012 MaxRtrAdvInterval
TS 129 061 11.2.1.3.4 MANDATORY
Applies to: Router
Context:

Requirement:
The default value of the configurable timer, MaxRtrAdvInterval in a 3GPP IPv6 router shall be
21,600s (6 hours).
Specification Text:
For IPv6 Stateless and Stateful Address Autoconfiguration to work properly the GGSN shall
behave as an IPv6 router towards the MS. In this respect the GGSN shall be consistent with the
RFCs specifying this process (for example RFC 2462 and RFC 2461), unless stated otherwise in
this or other 3GPP specifications.

RFC 2461 specifies a set of conceptual router configuration variables. Some of these variables
require particular attention in GPRS in order to preserve radio resources and MS power
consumption while still allowing for appropriate robustness and fast user-plane set-up time
even in bad radio conditions, or simply because they have a particular meaning in GPRS. These
particular variables are listed below with appropriate (default) values and shall be
configurable per APN. The values specified hereafter are specific to GPRS and supersede those
specified in RFC 2461.

MaxRtrAdvInterval

    Shall have a default value of 21 600 s (6 h).

MinRtrAdvInterval

    Shall have a default value of 0,75 × MaxRtrAdvInterval i.e.16 200 s (4,5 h).

AdvValidLifetime

    Shall have a value giving Prefixes infinite lifetime, i.e. 0xFFFFFFFF.
    The assigned prefix remains Preferred until PDP Context Deactivation.

AdvPreferredLifetime

    Shall have a value giving Prefixes infinite lifetime, i.e. 0xFFFFFFFF.
    The assigned prefix remains Preferred until PDP Context Deactivation.

RFC 2461 also specifies a number of protocol constants. The following shall have specific
values for GPRS:

MAX_INITIAL_RTR_ADVERT_INTERVAL

    This constant may be a variable within GPRS. It may have a value
    that gradually increases (exponentially or by some other means) with
    the number of initial Router Advertisements sent. This will enable a
    fast set-up of the MS-GGSN link in most cases, while still allowing
    the MS to receive a Router Advertisement within the initial phase,
    even in case of bad radio conditions or slow response time, without
    having to send a large number of initial Router Advertisements.

MAX_INITIAL_RTR_ADVERTISEMENTS

    This is the number of Router Advertisements sent during the initial
    phase after the MS-GGSN link has been established. The value of
    this constant shall be chosen carefully, and in conjunction with
    MAX_INITIAL_RTR_ADVERT_INTERVAL, so as to not overload the radio
    interface while still allowing the MS to complete its configuration
    in a reasonable delay. For instance, the default value could be
    chosen so that initial Router Advertisements are sent for at least 30 s.

    After the initial phase, the periodicity is controlled by the
    MaxRtrAdvInterval and the MinRtrAdvInterval constants.
