48、p the logical network model, and to indicate any unique aspects of these protocols that are relevant to the Interoperability Specification (IOS). 1.1.2 Scope 11 12 13 14 15 16 17 This document contains generic and specific requirements for the IOS interfaces. The document contains the generic protoc

49、ol descriptions that are used through all of the IOS interfaces. In addition, protocol stack and transport network requirements for each IOS interface are contained in this document. Details of the IOS application and signaling layer messages are contained in the respective interface documents 14, 15, 16, and 17. 1.2 References 18 19 20 21 22 References are either normative or informative. A normative reference is used to include another document as a mandatory part of a 3rd Generation Partnership Project 2 (3GPP2) specification. Documents that provide additional
