This default bearer will be allowed to carry all traffic that is not associated with a dedicated bearer. Restricting Outbound IPv6 Roaming Legacy devices and hosts that have an IPv4-only stack will continue to be provided with IP connectivity to the Internet and services. DHCPv6 prefix delegation has an explicit limitation, described in Section Connectivity Recommendations This section identifies the main connectivity recommendations to be followed by a cellular host to attach to a network using IPv6 in addition to what is defined in [RFC] and [RFC].
However, these factors are mitigated by the assurance that legacy devices and services are unaffected, and there is always a fallback to IPv4 in case of issues with the IPv6 deployment or network elements. Particularly, 1 name resolution libraries e. Concretely, this document lists means to ensure IPv4 service over an IPv6-only connectivity given 2400 adoption rate of this model by mobile operators.
Please review these documents 2408, as they describe your rights and restrictions with respect to this document. It represents st consensus of the IETF community.
IPv4 service continuity features are listed in this section because these are critical for operators with an IPv6-only deployment model. This result indicates the success or failure of the UE and test set to authenticate in In addition, the number of subscribers and devices using the 3GPP networks for Internet connectivity and data services has also increased phenomenally — the number of mobile broadband subscribers has increased exponentially over the last couple of years.
Chen China Mobile N. A Release-8 UE always requests a dual-stack bearer, but accepts what is assigned by the network.

More details can be found at. It might be in the interest of operators to prohibit roaming selectively within ta visited networks until IPv6 roaming is in place. Michaud Rogers Communications D. Please review these documents carefully, as they describe your rights and tw with respect to this document.
The cellular host must be able to generate IPv6 addresses that preserve privacy. The most relevant factor is essentially the same as the reason for IPv6 not being deployed in other networks either, i. Because of potential operational deficiencies to be experienced in some roaming situations, the cellular host must be able to be configured with a home PDP-Context type s and a roaming PDP-Context type s.
This could be used to apply different network quality of service parameters or even differential billing. During authentication, both the UE and the network confirm that the other is valid by a series of computations based on a shared secret Authentication Key K. Those operators require that no service degradation is experienced by customers serviced with an IPv6-only model compared to the level of service of customers with legacy IPv4-only devices. The authentication, location update, and subscription data acquisition procedures all use the serving PLMN.
This feature is optional and requires a license. Authentication, Integrity Protection and Ciphering is performed during call processing operations. Essentially, this indicates the following deployment options: The default mode is to allow all supported PDP types.

The more applications are address family independent, the less the CLAT function is solicited. Note, privacy extensions are required by regulatory bodies in some countries. This feature is useful to drive the behavior of the UE to be aligned with 1 service-specific constraints such as the use of IPv6-only for VoLTE, 2 network conditions with 3vpp to the support of specific PDP types e.
The number of UEs that 2008 gateway supports is on the order of 1 to 10 million.
The 24008 options for disabling IPv6 access for roaming subscribers could be available in some network deployments: However, there are network drivers that fail to pass the Interface Identifier to the stack and instead synthesize their own Interface Identifier usually a Media Access Control MAC address equivalent.
IPv6 in 3rd Generation Partnership Project (3GPP) Evolved Packet System (EPS)
In the light of recent IPv6 production deployments, additional features to facilitate IPv6-only deployments while accessing IPv4-only services should be considered. The PDN may be an operator-external public or private packet data network or an intra-operator packet data network. As shown in the figure, the shared network is set up by operator X and is shared with operators A, B, and C.
However, the authors believe that not supporting relevant features included in this profile e. A supporting UE is capable of deriving shared network information from broadcast system tts and can select a CN operator gs the 20408 network to serve it.
Obviously, the support of the full set of features may not be required in some deployment contexts. Enabling IPv6 connectivity in the 3GPP networks by itself will provide some degree of relief to the IPv4 address space, as many of the applications and services can start to work over IPv6.
Every dual-stack bearer still needs to be given an IPv4 address, private or public.
