TIA-1143 1-1 1 Introduction 1 This document defines the access network aspects of High Rate Packet Data (HRPD) systems that interwork with World Interoperability for Microwave Access (WiMAX) systems. 2 3 1.1 Overview 4 This do
40、cument includes a description of the interface protocols and procedures to support the features and functions described in section 5 6 7 8 9 10 15 1.13. Conformance to this standard may be claimed on a feature by feature and/or interface by interface basis. If conformance on a given interface is cla
41、imed for a feature, it shall be supported as defined in this standard. In addition to the features and functions included in A.S0008 1 and A.S0009 2, this specification explicitly supports the following features: 1. Active handoff from WiMAX to HRPD for a single transmitter MS/AT 11 2. Active handof
42、f from HRPD to WiMAX for a single transmitter MS/AT 12 3. Idle handoff from WiMAX to HRPD for a single transmitter MS/AT 13 4. Idle handoff from HRPD to WiMAX for a single transmitter MS/AT 14 This specification transparently supports the following features: 1. Handoff Between WiMAX and HRPD for Dua
43、l Transmitter MS/ATs 16 1.1.1 Purpose 17 The purpose of this document is to provide a standard and call flows for the HRPD Interoperability Specification (IOS) interfaces for interworking between WiMAX and HRPD systems. 18 19 1.1.2 Scope 20 This document provides an interoperability specification fo
44、r a Radio Access Network (RAN) that supports HRPD and handoff to and from WiMAX. The RAN architecture in this document logically locates the Session Control and Mobility Management (SC/MM) function in the Access Network (AN) for the architecture specified in A.S0008 21 22 23 24 25 26 1 and in the Pa
45、cket Control Function (PCF) for the architecture specified in A.S0009 2. This document contains message procedures and formats necessary to obtain this interoperability. 1.1.3 Document Convention 27 “Shall” and “shall not” identify requirements to be followed strictly to conform to the standard and
46、from which no deviation is permitted. “Should” and “should not” indicate that one of several possibilities is recommended as particularly suitable, without mentioning or excluding others; that a certain course of action is preferred but not necessarily required; or (in the negative form) that a cert
47、ain possibility or course of action is discouraged but not prohibited. “May” and “need not” indicate a course of action permissible within the limits of the standard. “Can” and “cannot” are used for statements of possibility and capability, whether material, physical, or causal. 28 29 30 31 32 33 34
