T-Labs, Aalto University, and Huawei provided test devices used in our experiments. Subscribers will not be able to receive or make normal calls and data connections. In this section, we show how the approximate location of 3gppp LTE subscriber inside an urban area can be inferred by applying a set of novel passive, semi-passive, and active attacks.

The following are some operational aspects to consider for running a network with IPv6-only bearers:. Downgrade to non-LTE services D1. IPv6 prefix delegation is a part of Release and is not covered by any earlier releases. Aforementioned measurement and RLF reports provide signal strengths allowing the active attacker to calculate distance between the UE and the rogue eNodeB. Universal Mobile Telecommunication System.

The results are summarized as follows: We then characterize preliminary measurements used for realizing the attacks and new techniques for triggering subscriber paging.

We argue that similar protection for network capabilities is required due to the fact that the DoS attack has a persistent nature. By leveraging a rogue eNodeB femtocellpreviously captured authentication parameters are replayed to the UE and the presence is confirmed based on the response from the phone.


GUTI reallocation depends entirely on operator configuration. We carefully analyzed LTE access network protocol specifications and uncovered several vulnerabilities.

3GPP TS (1 of 20) – Non-Access-Stratum (NAS) protocol for EPS

This suggests that the specification is ambiguous leading to incorrect interpretation by multiple baseband vendors. Provisioning of IP-based multimedia services. In this embodiment, the method may be applied 3gpo any tts communication device which is configured for NAS signaling low priority. Remarks 1 Creation date Author Remark. Mobile communication is an important cornerstone in the lives of hs vast majority of people and societies on this 42301.

Legacy devices and hosts that have an IPv4-only stack will continue to be provided with IP connectivity to the Internet and services. The second solution is more realistic as it does not require change in protocols. If the attach request is rejected due to NAS level congestion control, the network shall set the EMM cause value to 22 “congestion” and optionally assigns a back-off timer T The structure of the GUTI is illustrated in the figure below.

Stage 3 for Session management, bearer control and QoS aspects. Some of the IEs included in this message are explained below. Early 2G systems were known to have several vulnerabilities. The test UE was placed in one of the cells and remained stationary for the experiment duration. The model also enables operators to develop operational experience and expertise in an incremental manner.

Information about the current status of this document, any errata, and how to provide feedback 2401 it may be obtained at http: The results are summarized as follows:. Newer Posts Older Posts Home. The need for engineering the correct trade-offs between security and other requirements availability, performance, and functionality led to the vulnerabilities in the first place.


The attacker can also place passive sniffers in every cell to 3vpp up the localization procedure. The forthcoming fifth generation 5G technology will offer better possibilities to engineer agility and flexibility for security because software defined networking and cloud computing are among the key concepts of emerging 5G architectures.

In particular, we identify protocol-level and operational fixes that can be implemented by baseband vendors and mobile network operators. In particular, if the UE is not able to establish connection with the eNodeB then it may be necessary to send measurement reports without protection in order allow the network to identify technical reason behind the fault.

UE refers to the actual communication device which can be, for example, a smartphone.

ESM message container

This has a few known issues, especially when the IP 3gpl is made to believe that the underlying link has link-layer addresses. We show that the 224301 points in the trade-offs have shifted today compared to where they were when the LTE security architecture was being designed. Operators with large subscriber bases have multiple gateways, and hence the same [ RFC ] IPv4 address space can be reused across gateways.

A method for handling a request for emergency bearer services by a mobile communication device configured for NAS signaling low priority, comprising: The purpose of the EPS update result IE is to specify the result of tracking area updating procedure.
