23、 Spectrum Systems, February 1997. 1.2 Terminology This document uses the following “verbal forms” and “verbal form definitions”: 1. “should” and “should not” indicate items of interest that are highly desirable and particularly suitable, without identifying or excluding other items; or (in the negat

24、ive form) indicate items of interest that are not desirable, are not particularly suitable, or are not recommended but not prohibited, and 2. “may” and “may not” indicate items of interest that are optional but permissible within the limits of this recommendation. 1.3 Assumptions a. The architecture

25、 described in this document assumes the following protocols: 1. SIP (Session Initiation Protocol), 2. DIAMETER, and 3. MOBILE IP (i.e., IPv4 and/or IPv6). b. The use, support, and interoperation of IPv4 and IPv6 in the All-IP network is currently assumed in this document, but whether IPv6 should be

26、used exclusively needs to be strongly considered in ongoing work. c. There are known bearer paths not shown in Figure 2.1 (e.g., bearer paths between the Application Servers and the Border Router, the Application Servers and the Media Resource Function Processor). Some of these interfaces are shown

27、in additional diagrams in this document, but not numerically labeled, see Section 3. d. There are known signaling paths not shown in Figure 2.1 (e.g., signaling paths between two Call Session Control Functions (CSCFs), two AAA, an external SIP entity beyond the Border Router and the CSCF). Some of t

28、hese interfaces are shown in additional diagrams in this document, but not numerically labeled, see Section 3. 1.4 Architectural Principles The statements contained in this section should guide the development of the All-IP network architecture. While these statements are too general to be treated a

29、s specific requirements, they form a set of principles meant to govern the overall development of the All-IP network, they are: a. The All-IP network architecture should be independent of the underlying Layer 1 and Layer 2 protocols through the use of IP-based protocols. b. The All-IP core network s

30、hould be independent of the access network. The core network should have the ability to support multiple access network technologies (e.g., cable, radio access technologies, wireless LAN, DSL). The core network should have the ability to support access networks as they evolve and as new access techn

31、ologies are identified. This implies that network functions such as Copyright Electronic Industries Alliance Provided by IHS under license with EIANot for ResaleNo reproduction or networking permitted without license from IHS-,-,-TIA/TSB-151 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 2

How this independence is maintained for mobility management and location-based services (which may be depende

33、nt on access technology) is for further study. c. A phased migration of existing networks to the All-IP network should be possible. d. All pertinent interfaces in the All-IP network should be defined in an open manner. e. The All-IP network should promote efficient use of radio interface resources.

34、f. The All-IP network should be capable of supporting reliability levels equal to or better than those found in legacy networks. g. The All-IP network should support capabilities for rapid service creation, including service creation by the user and by third parties as well as service profile custom

35、ization by end users. h. The All-IP network should permit separate signaling and bearer paths. i. The All-IP network architecture and protocols should be scalable. j. The All-IP network architecture development process should aim to identify and reuse solutions from other initiatives within the IMT-

36、2000 family (especially 3GPP), whenever possible and reasonable. k. The All-IP network should support Quality of Service equal to or better than that found in legacy networks. l. The All-IP network architecture should be defined in terms of separate functions and clear interfaces such that it is pos

37、sible to separate bearer from signaling. m. The All-IP network should be functionally designed to allow and encourage reduced complexity and/or resource utilization. n. The All-IP network should support a range of terminal types (e.g., voice-only terminals, IP Multimedia terminals, laptop computers)

38、. Not all these terminals may be able to support end-to-end IP capabilities (e.g., 2G and 3G legacy terminals). o. The All-IP architecture should be designed in such a way that a migration from IPv4 to IPv6 is feasible and that IPv4 and IPv6 based All-IP networks may interoperate. 1.5 Legend This se

42、 to a communications session. These capabilities can be specified so that particular applications (e.g., voice, video, streaming audio) fulfill human factors or other requirements with respect to fidelity and performance. QoS in a packet network consists of at least the following components: a. Band

43、width: Data rate (e.g., 64 kbps), b. Delay: End-to-end or roundtrip latency (e.g., 300 ms), c. Jitter: Inter-packet latency variation (e.g., 10 ms), and e. Loss: Rate at which packets are dropped (e.g., 3%). Additionally, this QoS may be: a. unidirectional or bidirectional, b. guaranteed or statisti

44、cal, c. end-to-end or limited to a particular domain or domains, and e. applied to all traffic or just to a particular session or sets of sessions. Wireless Network Operator (WNO) A network operator offering wireless services using the architecture defined by 3GPP2. This architecture may also suppor

45、t other access technologies.
