The simplest solution is to transmit measurement reports only after setting up the security context. The Home Location Register HLR is a pre-Release-5 database but is also used in Release-5 and later networks in real deployments that contains subscriber data and information related to call routing.

Various combinations of subscriber provisioning regarding IP versions are discussed further in Section 8. Signalling Improvements for Network Efficiency Stage 3.

Specifically, these experiments verify whether GUTIs are really temporary in practice. The primary intention of the attacker is to trigger paging requests via social identities without LTE subscribers being aware of it. Furthermore, even if individual app developers would fix their applications e. It might be in the interest of operators to prohibit roaming selectively within specific visited networks until IPv6 roaming is in place.


In this section, we explain our experimental setup built using low cost off-the-shelf components and requiring only elementary programming skills with knowledge of LTE specifications. Meetings Version Upload date Comment.

Mapping tracking area and cell dimensions: In passive attacks, Kune et al.

How LTE Stuff Works?: November

The visited network might not be commercially ready for IPv6 outbound roamers, while everything might work technically at the user-plane level. The LTE suite of specifications is considered to be significantly better than its predecessors not only in terms of functionality but also with respect to security and privacy for subscribers. Prime Rapporteur has been changed to Gabor Ungvari. The evolution of these mobile communication systems specified by 3GPP Third Generation Partnership Project have not only incorporated improvements in functionality but also strengthened security.

The distance estimates are calculated as d1, d2, and d3 for three neighboring base stations. IPv6 prefix delegation is a part of Release and is 3gp; covered by any earlier releases. This also allows independent scaling, growth of traffic throughput, and control-signal processing.

ESM message container

In particular, this knowledge enables an attacker to identify targeted TAs for specific regions and 3gop operators in the city. The wireless module performs wireless transmissions and receptions to and from a service network.

Finally, we explain the attacks in detail. Prefix Delegation IPv6 prefix delegation is a part of Release and is not covered by any earlier releases. Two PDP contexts are needed to get dual-stack connectivity. Thus, with the setting 42301 the service type to “packet service via S1 for emergency bearer services”, both of the UE NAS layer and the core network i.


The number of UEs that a gateway supports is on the order of 1 to 10 million. This is a major concern with dual-stack bearers concerning IPv6 transition.

In particular, we exploit two functions of EMM 3gpp described below. It is compliant with LTE specifications and consists of directing paging messages selectively via the eNodeB cell where 2401 UE was last seen. This feature is not yet widely supported by current smartphones – however one of our test phone exhibited this behavior.

This solution would protect against passive attacks L1. An application on the host, such as a web browser, would use the PDP context that provides Internet ta for accessing services on the Internet.

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. There are two solutions to avoid UEs being tracked. As a result, the emergency bearer services will not be prioritized as they should be.
