List in one single document a comprehensive list of IPv6 features for a mobile device, including both IPv6-only and dual-stack mobile deployment contexts. Michaud Rogers Communications D. Special thanks to T. This is necessary because a device may have multiple PDP contexts and application endpoints. Acknowledgements Many thanks to C. The UE is allowed to use any Interface Identifier it wishes for the other addresses it configures. Several cases are discussed in the following sections.

Each telecommunications operator providing mobile services has its own PLMN. The control-plane traffic always goes through the SGSN.

MM or Authentication Result: The basic EPS architecture is illustrated in Figure 4. A UE may hence be attached to one or more gateways via separate connections, i. Some of the issues and concerns with respect to deployment and shortage of private IPv4 addresses within a single network domain are also discussed.

The authentication sequence number SQN is set to zero each time the test set is powered on. See Note 1 below. A Release-8 UE always requests a dual-stack bearer, but accepts what is assigned by the network.


The PDN may be an operator-external public or private packet data network or an intra-operator packet data network. This also allows independent scaling, growth of traffic throughput, and control-signal processing. This is also a contribution to harmonize operators’ requirements towards device vendors. As shown in the figure, the shared network is set up by operator X and is shared with operators A, B, and C.

The IPv4 address assigned to a UE is unique within the scope of a single gateway. This site uses cookies. Only those core network nodes that must be connected to the inter-operator roaming networks are actually visible there, and are able to send and receive tunneled traffic within the inter-operator roaming networks. As the networks evolve to support Release-8 EPS architecture and the dual-stack PDP contexts, newer devices will be able to leverage such capability and have a single bearer that supports both IPv4 and IPv6.

The two PDP contexts of different type may use the same APN and the gateway ; however, this aspect is not explicitly defined in standards. In some cases, a network can specify an. This result indicates the success or failure of the UE and test set to authenticate in the CS domain. You could perhaps use deep-packet inspection to search out 2.


Techniques are described that can be used for efficient mobility management signaling. The choice of using IPv6 or IPv4 depends on the capability of: An application on the host, such as a web browser, would use the PDP context that provides Internet connectivity for accessing services on the Internet. It then increments each time an authentication procedure is performed. Benefits Table 1 Benefits of this feature For A supporting UE is capable of deriving shared network information from broadcast system information and can select a Fs operator from the shared network to serve 42008.


Cellular networks are more and more perceived as an alternative to fixed broadband networks for home IP- based services delivery; especially with the advent of smartphones and 3GPP data dongles. Obviously, in order for the roaming to work properly, the operators have to agree on supported protocol versions so that the visited network does not, for example, unnecessarily drop user-plane IPv6 traffic.

John’s Road Dublin 8 Ireland Email: The IETF continues to specify additional solutions for enabling the transition based on the deployment scenarios and Korhonen, et al.

This information element contains only the Interface Identifier of the IPv6 address. Authentication, Integrity Protection and Tts is performed during call processing operations.

The purpose of the roaming profile is to limit the PDP type s requested by the cellular host when out of the home network. All subscribers of an operator, and the subscribers’ enabled services, are provisioned in the HLR.
