Foreword This Technical Report (TR) has been produced by ETSI Technical Committee Reconfigurable Radio Systems (RRS). Modal verbs terminology In the present document “should“, “should not“, “may“, “nee
23、d not“, “will“, “will not“, “can“ and “cannot“ are to be interpreted as described in clause 3.2 of the ETSI Drafting Rules (Verbal forms for the expression of provisions). “must“ and “must not“ are NOT allowed in ETSI deliverables except when used in direct citation. Executive summary The introducti
24、on of RRS capability is shown not to inhibit the provision of the security mechanisms of existing radio access technologies. The reason, shown in the present document, is that the security capabilities for common radio technologies (e.g. LTE/SAE, IEEE 802.11) are present at layers 2 and higher in th
25、e OSI protocol stack, whereas the novel features of RRS apply to the means to provision layer 1. It is highlighted however that a Radio Application addresses a complete protocol stack and provision of all layers of the protocol stack in a single software package may require special provisions in the
26、 Reconfigurable Equipment to enable full network communication. ETSI ETSI TR 103 502 V1.1.1 (2017-09) 6 1 Scope The present document shows a mapping of existing Radio Access Technologies (RATs) to the Reconfigurable Radio System (RRS) model in order to identify missing security requirements, in part
27、icular identify the boundary of an RRS Radio Application with regard to the security functions present in existing RAT. Recognizing that a RAT is not bound to a single link but may be supported by functions in the network the present document also considers the role of core networks in supporting an
28、y triggering of the Reconfigurable Equipment to reconfigure itself using a push mechanism. 2 References 2.1 Normative references Normative references are not applicable in the present document. 2.2 Informative references References are either specific (identified by date of publication and/or editio
