24、003 1-4 1.4.2 Definitions 1 Access Authentication A procedure in which the Access Terminal (AT) is authenticated by the AN-2 AAA (Access Network Authentication, Authorization and Accounting entity). 3 Access Stream The HRPD stream whose end-points are the access terminal and the access net-4 work (r
25、adio network). This stream is used for access authentication. 5 Access Network The network equipment providing data connectivity between a packet switched 6 data network (typically the Internet) and the access terminals. An access network 7 is equivalent to a base station in cdma2000 systems. 8 Acce
26、ss Terminal A device providing data connectivity to a user. An access terminal may be 9 connected to a computing device such as a laptop personal computer or it may be 10 a self-contained data device such as a personal digital assistant. An access 11 terminal is equivalent to a mobile station in cdm
27、a2000 systems. 12 AN-AAA An entity that performs access authentication and authorization functions for the 13 Access Network. 14 Connection A connection is a particular state of the air-link in which the access terminal is 15 assigned a Forward Traffic Channel, a Reverse Traffic Channel and associat
28、ed 16 Medium Access Control (MAC) Channels. During a single HRPD session the 17 access terminal and the access network can open and can close a connection 18 multiple times. 19 Hybrid MS/AT A device capable of operating on both cdma2000 and HRPD access networks. 20 Service Stream The HRPD stream use
29、d when exchanging data between the access terminal and 21 the PDSN. 22 HRPD session An HRPD session refers to a shared state between the access terminal and the 23 access network. This shared state stores the protocols and protocol configurations 24 that were negotiated and are used for communicatio
30、ns between the access 25 terminal and the access network. Other than to open a session, an access terminal 26 cannot communicate with an access network without having an open session. 27 Note that it is possible that the A10/A11 connection is not established even 28 though the HRPD session is establ
31、ished. Refer to 10, Section 1.9. 29 Packet Data Session An instance of use of packet data service by a mobile user. A packet data session 30 begins when the user invokes packet data service. A packet data session ends 31 when the user or the network terminates packet data service. During a particula
32、r 32 packet data session, the user may change locations but the same IP address is 33 maintained.

36、P supports mobility between PDSNs under the same Home Agent. 12 1.7 Compatibility with IS-2001 Standards 13 The HRPD IOS interface, as defined in this specification, is compatible with a TIA/EIA/IS-2001 or high-14 er release, with the provision that the HRPD capabilities are the same as those suppor
37、ted by the inter-15 operability specification, for the access network(s) in use. For example, when inter-operating with a 16 TIA/EIA/IS-2001 system, the portions of this specification related to concurrent services and support for 17 Previous/Current Access Network Identifiers (PANID/CANID) are not
38、applicable. 18 Note: When the procedures between TIA/EIA/IS-95-B or cdma2000 and HRPD systems differ, the 19 HRPD procedures are identified separately within this specification. When the TIA/EIA/IS-2001 text is 20 Copyright Telecommunications Industry Association Provided by IHS under license with E
39、IANot for ResaleNo reproduction or networking permitted without license from IHS-,-,-TIA-878-1 IOS HRPD May 2003 1-6 applied to the HRPD RAN specification, the procedures related to the MSC shall be ignored. Hard Hand-1 off procedures, as defined in 11, are not applicable to HRPD. 2 3 1.8 HRPD IOS A
40、ssumptions 4 The following assumptions are made regarding AN/AT behavior: 5 1. A packet data session may transition from a serving cdma2000 system to a serving HRPD system and 6 from a serving HRPD system to a serving cdma2000 system. 7 2. A unique value, 59 (3BH), is used in the Service Option fiel
41、ds in accounting records transported on 8 the A9 and A11 interfaces to identify accounting records associated with HRPD packet data service. 9 3. For the case of dormant inter-AN inter-PCF handoff, the target PCF may use the PDSN address 10 received from the source AN to send the A11-Registration Re
42、quest message. Otherwise, the target 11 PCF shall use the PDSN selection algorithm (if supported and if the IMSI is available) or internal 12 algorithms to select a PDSN. 13 4. Following a dormant handoff, the target AN sends the SID, NID, PZID triplet (ANID), if received 14 from the AT, to the targ
43、et PCF. If the AT does not send the ANID, or the AN chooses not to request 15 this information from the AT, then the target AN may send the ANID received in the A13-Session 16 Information Response message from the source AN. If the target PCF supports ANIDs, then it sets 17 the PANID to the ANID rec
44、eived from the AN, and the CANID to its own ANID in the A11 18 messages. 19 5. For the instance of Packet Application terminated in the AN, the AT shall support Challenge 20 Handshake Authentication Protocol (CHAP) access authentication. In this case, the AT shall send a 21 Network Access Identifier
45、 (NAI) of the form specified in 24. 22 6. For the instance of Packet Application terminated in the AN (i.e., AN access authentication), the gen-23 eration of the NAI and password are the responsibility of the service provider. The NAI and password 24 should be chosen and managed using procedures tha
46、t minimize the likelihood of compromise. 25 7. If the access authentication feature is used, the AN shall always propose CHAP as a PPP option in an 26 initial Link Control Protocol (LCP) Configure-Request during the PPP establishment. 27 8. The Mobile Node Identification (MN ID) that is used by the
47、AN and the PCF on A8/A9 and A10/A11 28 messages is unique within the operators network, and is determined as follows: 29 - If the HRPD AN uses the access authentication feature, the MN ID field shall be set to the MN ID 30 value returned by the AN-AAA (e.g., IMSI) following successful access authent
48、ication. 31 - Otherwise, the AN/PCF shall set the MN ID field to a value that conforms to a valid MN ID 32 format (i.e., IMSI format). In this case, the MN ID is determined by other means. 33 9. After the AT indicates it is ready to exchange data on the access stream, the AT and the AN initiate 34 P
49、PP procedures according to 19. 35 10. The AT may support packet data service as specified in 9. 36 37 38 Copyright Telecommunications Industry Association Provided by IHS under license with EIANot for ResaleNo reproduction or networking permitted without license from IHS-,-,-TIA-878-1 May 2003 IOS HRPD 2-1 2 HRPD IOS Interfaces 1 This section describes the Radio Access Network interfaces associ
