This results can also be queried by CALL: The IPv6-only behavior is up to subscription provisioning or PDN-GW configuration, and the fallback scenarios do not necessarily cause additional signaling.
The PDN may be an operator-external public or private packet data network or an intra-operator packet data network. The purpose of the roaming profile is to limit the PDP type s requested by the cellular host when out of the home network. Also, this profile sketches recommendations for the sake of deterministic behaviors of cellular devices when the same configuration information is received over several channels.
Renumbering without closing the layer-2 connection is also not possible. The user-plane traffic bypasses the MME. These recommendations apply for mobile hosts, including mobile devices. The document also contains sections covering specific functionalities for devices providing some LAN functions e. Moreover, this profile also covers cellular CE routers that are used in various mobile broadband deployments. The support of dynamic means is encouraged.
New services requiring direct connectivity between UEs should be built on IPv6. The most relevant factor is essentially the same as the reason for IPv6 not being deployed in other networks either, i. Operational Aspects of Running Dual-Stack Networks Operating dual-stack networks does imply cost and complexity to a certain extent.
Release History Table 7 describes the release history of this feature. It does not require additional protocol to be supported by the cellular host and it is already deployed in IPv4 cellular networks to convey such DNS information. This will also ensure that legacy devices and applications continue to work with no impact. In the light of recent IPv6 production deployments, additional features to facilitate IPv6-only deployments while accessing IPv4-only services should be considered.
Multiple carriers use the same set of devices, which reduces their costs. The deferred address allocation is based on the use of DHCPv4 as well as appropriate UE-side implementation- dependent triggers to invoke the protocol. An application such as a MMS would use APNy in the figure above, because the service is provided through the private network. Subscribers Subscribers can choose carriers and therefore can enjoy differentiated services provided by these carriers.
This information element contains only the Interface Identifier of the IPv6 address. The underlying transport for these reference points can be IPv4 or IPv6. It then increments each time an authentication procedure is performed. PCO is a convenient method to inform the cellular host about various services, including DNS server information.
Legacy devices and hosts that have an IPv4-only stack will continue to be provided with IP connectivity to the Internet and services. This document is not a standard, and conformance with it is not required in order to claim conformance with IETF standards for IPv6.
Binet Request for Comments: In addition, a lot of work has been invested by the industry to investigate different transition and deployment scenarios over the years.

One of the major hurdles as perceived by some mobile operators is the lack of availability of working IPv6 implementation in mobile devices e. This result indicates the success or failure of the UE and test set to authenticate in the CS domain.
Security Considerations This document does not introduce any security-related concerns. My proposal is to use the previously reserved NSAPI values to identify an endpoint that is terminated on an external tethered device. Avoiding soliciting ALGs makes it easier to develop a service without any adherence with the underlying transport network.

Status of This Memo This document is not an Internet Standards Track specification; it is published for informational purposes. Non-GBR bearers can suffer packet loss under congestion, while GBR bearers are immune to such losses as long as they honor the contracted bit rates.
As discussed in Section 5. By using these reserved values the SGSN can distinguish between on-device data and tethered connections.
