Embodiment 1

[0233] Example embodiments 1. A method performed by a wireless device for identifying and preventing attacks by a fake base station during a rejection procedure, the method comprising: determining that an RRCReject message was sent by a fake base station and / or was tampered with.

Embodiment 2

[0234] Example embodiment 2. The method of embodiment 1, wherein the determining is based on verifying a signature in the RRCReject message.

Embodiment 3

[0235] Example embodiment 3. The method of embodiment 1, wherein the determining is based on a predetermined network deployment.

Abstract

A method performed by a wireless device includes receiving a Radio Resources Control Reject (RRCReject) message and determining whether to act on the RRCReject message based on a configuration of the wireless device. The method may also include receiving a configuration message that includes the configuration from a network node.

Description

Background technique [0001] The 3GPP NR / NG-RAN architecture is described in e.g. TS 38.300 v.15.3.0 subclause 4.1 as follows: [0002] NG-RAN nodes are either: [0003] - gNB, providing NR user plane and control plane protocol termination towards UE; either [0004] - ng-eNB, providing E-UTRA user plane and control plane protocol termination towards UE. [0005] The gNB and ng-eNB are interconnected with each other by means of the Xn interface. gNB and ng-eNB are also connected to 5GC by means of NG interface, more specifically, to AMF (Access and Mobility Management Function) by means of NG-C interface and to UPF (User Plane Function) by means of NG-U interface ) (see 3GPP TS 23.501 [3]). [0006] Note: The F1 interface and architecture for functional splitting are defined in 3GPP TS 38.401 [4]. [0007] figure 1 Diagram showing the NG-RAN architecture. [0008] The Access Stratum (AS) is composed of the parts in the user equipment (UE) and in the infrastructure and th...
