1 1 Introduction

2 This document defines requirements for support of wireless packet data networking capability on ®1 3 a third generation wireless system based on cdma2000 . This document supports the services 4 and architecture in [1].

5 This document defines the two methods for accessing public networks (Internet) and private 6 networks (intranets): Simple IP and MIP. It describes the required Quality of Service, Security, 7 Mobility Management, and Accounting capabilities needed to support both methods. IETF 8 protocols are widely employed whenever possible to minimize the number of new protocols 9 required and to maximize the utilization of well accepted standards.

10 This document is organized into a series of related chapters, some of which address capabilities 11 common to both IP access service types: MIP and Simple IP, and others may describe 12 capabilities applicable to a specific IP access service. The chapters included in this series are:

13 Chapter 1 cdma2000 Wireless IP Network Standard: Introduction.

14 Chapter 2 cdma2000 Wireless IP Network Standard: Simple IP and MIP Access Services.

15 Chapter 3 cdma2000 Wireless IP Network Standard: Packet Data Mobility and Resource 16 Management.

6 A6 Resource Record:

7 In the DNS, the A6 resource record type [RFC 2874] is a record specific to 8 the Internet class that stores IPv6 address.

9 A10 Connection:

10 A connection between a PCF and a PDSN that uses a GRE tunnel to 11 transport user data for one or more IP flows for an MS. This is the A10 12 connection specified in [4].

13 A10 Interface:

14 The interface between the PCF and PDSN that transports user traffic as 15 specified in [4].

16 A10 Network:

17 An IP network as defined in [4] connecting the PCFs with the PDSNs.

19 The interface between the PCF and PDSN that carries signaling information 20 as specified in [4].

21 Access Provider Network:

22 A cdma2000 network that provides access to cdma2000 users.

23 Always On:

24 The Always On Service maintains the subscriber's packet data session in 25 the local network (i.e., for Always On service, the PDSN does not initiate 26 release of the subscriber's packet data session, unless the PDSN 27 determines the user is no longer reachable).

28 Auxiliary Link Flow:

29 For HRPD, an auxiliary link flow refers to a link flow that is in addition to the 30 main link flow and is initiated on a per need basis, e.g., when a service such 31 as VoIP is invoked.

32 Auxiliary Service Connection:

33 A logical connection between the MS and the PDSN that is in addition to the 34 main service connection and is established on a per need basis, e.g., when 35 a service such as VoIP is invoked. The data for an auxiliary service 36 connection is usually carried over an auxiliary link flow (HRPD)/auxiliary 37 service instance (cdma2000 1x) and corresponding auxiliary A10 38 connection.

39 Auxiliary Service Instance:

2. Glossary and Definitions 8 3GPP2 X.S0011-001-D v1.0

1 A cdma2000 1x term, auxiliary service instance refers to an additional 2 service instance (in addition to the main service instance) that is initiated on 3 a per need basis, e.g., when a service such as VoIP is invoked.

4 Broker RADIUS Server:

5 An intermediate RADIUS server that has security relationships with the 6 Visited RADIUS server and the Home RADIUS server and is used to 7 securely transfer RADIUS messages between the Visited Access Provider 8 Network and the Home IP Network. In some situations, there may be more 9 than one broker RADIUS server in the path between the Visited RADIUS 10 server and the Home RADIUS server.

11 Broker RADIUS Network:

12 A collection of administrative domains that contain Broker RADIUS servers.

13 Default Treatment:

14 The default treatment is the header and payload compressions that are 15 applied to a packet. The particular compression technique for a given 16 packet is chosen from the set of techniques negotiated during IPCP and 17 CCP.

18 Fast Handoff:

19 An inter PDSN based low latency handoff between PCFs. Fast handoff 20 between two PDSNs allows a mobile’s PPP session to be maintained via a 21 layer two tunnel passing through a Target PDSN to the Serving PDSN. 22 Note: There is also an intra PDSN fast handoff that is described in [4] that is 23 outside the scope of this document.

24 Handoff:

25 In this document the term "handoff" is defined to mean continuity of IP 26 bindings or PPP link layer state during an interface change from one entity to 27 another. In the absence of any continuity of state whatsoever, this document 28 does not refer to such interface changes as "handoffs".

29 Home RADIUS:

30 The RADIUS server that resides in the Home IP Network.

31 HAAA:

32 The AAA server that resides in the Home IP Network.

33 Home Access Provider Network:

34 A cdma2000 wireless network that is the home for the mobile subscriber.

35 Home Address:

36 An MS IP address that remains unchanged regardless of the MS's point of 37 attachment to the network.

38 Home IP Network:

39 The home network that provides IP based data services to the user. This 40 network is where the user's NAI is homed. This network may be a private 41 network, publicly accessible ISP network, or a cdma2000 wireless network.

42 Hot-Line Application:

2. Glossary and Definitions 9 3GPP2 X.S0011-001-D v1.0

1 The Hot-Line Application is the target of redirection of a hot-lined user’s 2 packet data service. The Hot-Line Application is responsible for notifying the 3 user of their Hot-Line status, and interacting with the user to resolve the 4 reason for which he/she was put in the Hot-Lined state. The Hot-Line 5 Application interacts with the HAAA instructing it to Hot-Line a user or to turn 6 Hot-Lining off. The specification of the Hot-Line Application is outside the 7 scope of this document.

8 Hot-Line Device:

9 The Hot-Line Device is the PDSN or the HA that is communicating with the 10 Home RADIUS Server for the purpose of Hot-Lining the user’s packet data 11 session.

12 Hot-Lined User:

13 A Hot-Lined user is a user whose packet data service has been redirected to 14 a Hot-Line Application and/or blocked by the operator.

15 Intra PDSN Handoff:

16 A handoff that is between PCFs with direct connectivity to the same PDSN.

17 Inter PDSN Handoff:

18 A handoff that is between PCFs with connectivity to different PDSNs.

19 IP Flow:

20 A series of packets that share a specific instantiation of IETF protocol layers. 21 For example, an RTP flow may consist of the packets of an RTP/UDP/IP 22 protocol instantiation, all of which share the same source and destination IP 23 addresses and UPD port numbers.

24 Link Flow:

25 For HRPD, a link flow is an octet or a packet data stream between an MS 26 and the RAN. Associated with each link flow are one or more 27 ReservationLabels. This document defines two categories of link flow, a 28 main link flow and auxiliary link flow. A link flow corresponds to an RLP flow 29 in [15].

30 Link Local Address:

31 An IPv6 address whose scope is local to a link.

32 Main A10 Connection:

33 A connection of type SO33 or SO59 between a PCF and a PDSN that uses 34 a GRE tunnel to transport user data and PPP signaling.

35 Main Link Flow:

36 For HRPD, the link flow that carries ReservationLabel 0xFF. This 37 specification allows exactly one main link flow per MS.

38 Main Service Connection:

39 Refers to the logical connection established between the MS and the PDSN 40 over which user traffic and PPP signaling is carried. A main service 41 connection is carried over the main link flow (HRPD)/main service instance

2. Glossary and Definitions 10 3GPP2 X.S0011-001-D v1.0

1 (cdma2000 1x) and the corresponding main A10 connection. This 2 specification allows exactly one main service connection per MS.

3 Main Service Instance:

4 For cdma2000 1x, an MS initiated connection between the MS and the RAN 5 of SO 33. This specification allows exactly one main service instance per 6 MS.

7 MIP:

8 In this document set the when the term MIP appears we are refers to 9 functionality or capabilities that apply to both MIP4 (Mobile IPv4) and MIP6 10 (Mobile IPv6).

11 MS-directed Flow ID-to-A10 connection Mapping:

12 A technique where the MS signals the PDSN explicitly the mapping of IP 13 flow(s) to an A10 connection.

14 Non-specific Traffic Flow Template:

15 A Non-Specific TFT has the NS bit is set to 1. The PDSN gets the mapping 16 of the flows to the A10 connections from the RAN (see RAN-directed 17 FLOW_ID-to-A10 connection mapping) via A11 signaling. For Non-Specific 18 TFT, the PDSN has one TFT for each MS IP address in support of RAN- 19 directed FLOW_ID-to-A10 connection mapping.

20 Packet Data Service:

21 A general term used for any packet switched data service offered by an 22 access provider network to a user through the user’s MS.

23 Packet Data Service Option:

24 A number specified in [13] that is used to identify a packet switched data 25 service. A packet data service option may be of type 33, 66 [11], 60/61[16], 26 59 [17], 64 [17,18] or 67[13, 17, 18].

27 Packet Data Session:

28 Describes continuous use of packet data service by the user. A packet data 29 session begins when the user invokes packet data service. A packet data 30 session ends when the user or the network terminates packet data service. 31 During a particular MIP packet data session, the user may change its point 32 of attachment while maintaining the same home address.

33 For Simple IP service, changing points of attachments constitutes a change 34 in packet data session because a new IP address is assigned by the new 35 point of attachment. For Simple IP service, a packet data session and a 36 PPP session are concurrent, where as for MIP service, the packet data 37 session can exist through several changes of the PPP session.

38 Point of Attachment:

39 Point of attachment refers to the node where the MS is connected to access 40 the IP network. In the context of this document, it refers to the PDSN entity.

41 Pi:

42 Pi is the interface between the PDSN and the public Internet.

2. Glossary and Definitions 11 3GPP2 X.S0011-001-D v1.0

1 P-P Connection:

2 A connection between a Serving and a Target PDSN that uses a GRE tunnel 3 to transport user data for a single service instance during fast handoff.

4 P-P Interface:

5 The interface between the Target PDSN and the Serving PDSN that is used 6 to support fast handoff.

7 P-P Session:

8 The set of all P-P connections for a single MS.

9 PPP Session:

10 A PPP session describes the time during which the Main Service Connection 11 is maintained between the MS and the Serving PDSN. The PPP session is 12 maintained while the MS is dormant. If a user hands off from one RAN to 13 another RAN but is still connected to the same PDSN, the PPP session 14 remains.

15 PrePaid Packet Data Service:

16 A function that allows a user to pay in advance for the use of packet data 17 service.

18 PrePaid Server (PPS):

19 A function that manages prepaid accounts for the users. It maintains the 20 PrePaid accounts on a per user basis or on a per service type basis for a 21 user. It communicates with the PrePaid client for control of the PrePaid 22 packet Data Service.

23 PrePaid Client (PPC):

24 A function that resides in the wireless IP network and communicates with the 25 PrePaid Server function (PPS) to control the prepaid user’s packet data 26 session. It requests PrePaid account authorization for a user and monitors 27 the user’s packet data session to determine when the limits of the 28 authorization are reached.

29 PrePaid User:

30 A user who paid for the packet data service in advance. The user is charged 31 by either the wireless IP Network Provider or a 3rd Party Packet PrePaid 32 Service Provider.

33 Private Address:

34 An IP address conforming to [RFC 1918].

35 Private Network:

36 An IP Network that is isolated from the global Internet. Generally this type of 37 network may reside behind a firewall, proxy-servers or a NAT (-PT) and may 38 use private IPv4 addresses.

39 QoS BLOB:

40 An object containing a set of QoS Sub BLOBs for one or more Flow IDs. It 41 also specifies the operation to be performed by the RAN upon receipt from

2. Glossary and Definitions 12 3GPP2 X.S0011-001-D v1.0

1 the MS of the QoS Sub BLOB for a Flow ID, such as add/update/remove. 2 The QoS BLOB is only used by cdma2000 1x mobiles.

3 QoS Sub BLOB:

4 An object containing a set of QoS parameter values or QoS Flow Profile IDs 5 for one Flow ID. A QoS Sub BLOB can be Requested (by the mobile) and 6 Granted (by the RAN) and updated (by the PDSN). This object is used in 7 both cdma2000 1x and HRPD systems.

8 RADIUS:

9 The specific AAA server implementation used in cdma2000 networks for 10 AAA functionality. The RADIUS servers may be located in the Home IP 11 Network, the Broker RADIUS Network, or the Visited Access Provider 12 Network.

13 Radio Access Network:

14 The RAN is equivalent to the BS and the PCF as defined in the Network 15 Reference Model [14]. In this document, the terms PCF and RAN are used 16 interchangeably when describing handoffs across the A10 interface. The 17 RAN is equivalent to the Radio Access Network (RAN) specified in [4].

18 RAN-directed FLOW_ID-to-A10 connection Mapping:

19 The mechanism where the PDSN determines the mapping of an IP flow to 20 an A10 connection based on IP flow identifier information received both from 21 the MS via TFT and from the RAN via A11 signaling.

22 Reservation:

23 Air interface resources set up by the access network to carry one or more IP 24 flows. A reservation is identified by its ReservationLabel. A 25 ReservationLabel is bound to a link flow.

26 ReservationLabel:

27 A one octet number that, along with the direction of the corresponding IP 28 flow(s), identifies a Reservation. A ReservationLabel is referred to as Flow 29 Id in this document.

30 Service Connection:

31 A logical connection between an MS and PDSN used to transport user data 32 for the MS. There are two types of service connection: main and auxiliary 33 (see Main service connection and auxiliary service connection.) Each 34 service connection is comprised of two parts: MS to RAN and RAN to PDSN. 35 In cdma2000 1x, the MS to RAN portion is called a service instance (see 36 service instance.) In HRPD, the MS to RAN portion is called a link flow (see 37 link flow.) In both cdma2000 1x and HRPD, the RAN to PDSN portion is 38 called the A10 connection (see A10 connection.) Under some 39 circumstances the IP flow can be carried on a different link flow/service 40 instance from the link flow/service flow normally associated to an A10 41 connection.

42 Service Instance:

43 For cdma2000 1x, a connection between an MS and RAN used to transport 44 user data for a packet data service.

2. Glossary and Definitions 13 3GPP2 X.S0011-001-D v1.0

1 Serving PDSN:

2 A PDSN that supports the PPP session to an MS.

3 Serving A10 Address:

4 The A10 network interface IP address of the Serving PDSN or that of the 5 Target PDSN when fast handoff is used.

6 Serving P-P Address:

7 The P-P network interface IP address of the Serving PDSN.

8 Specific Traffic Flow Template:

9 A Specific TFT is used for cdma2000 1x MS only. A specific TFT has the 10 NS bit set to 0. The PDSN determines the mapping of the IP flows to the 11 A10 connections from the TFT itself using the SR_ID. For a Specific TFT, 12 there is one TFT for each MS IP address and A10 connection pair.

13 SR_ID:

14 Used in cdma2000 1x, a unique number assigned to each service instance.

15 Target PDSN:

16 A PDSN that co-operates with a Target RAN over the A10 interface, and co- 17 operates with the Serving PDSN over the P-P interface to provide link layer 18 tunneling between the Serving PDSN and the Target RAN in the context of a 19 fast handoff.

20 Target P-P Address:

21 The P-P network interface IP address of the Target PDSN.

22 Traffic Flow Template:

23 The Traffic Flow Templates (TFT) may include packet filter(s) that identify 24 the IP flow(s) in both the forward and reverse directions as indicated by the 25 MS. The TFTs are used to map forward traffic to the main or the auxiliary 26 A10s and to indicate if a specific flow treatment (e.g. Header Compression 27 technique) should be applied for the forward packet that matches the packet 28 filter. In the reverse direction, the TFT is used for accounting purposes. 29 There are two types of TFTs: specific and non-specific (see Specific Traffic 30 Flow Template and Non-specific Traffic Flow Template).

31 User Profile:

32 The User Profile is an abstraction for the collection of all the parameters 33 applied to the user. The User Profile includes the Subscriber QoS profile 34 (which itself includes the Allowed Differentiated Services Marking and 35 Service Option profile).

36 Visited Access Provider Network:

37 The visited service provider provides access services through the 38 establishment of a service agreement with a home service provider.

39 Visited RADIUS:

40 The RADIUS server that resides in the Visited Access Provider Network.

1 4 Protocol Reference Models

2 This section specifies the protocol architecture between the entities of the Wireless IP Network 3 architecture. Refer to [1] for the description of the Wireless IP Network architecture, its 4 components and message flows. To support fast handoff, an optional interface between PDSN 5 entities is defined in this document. The architecture in [1] for both MIP and Simple IP has been 6 amended to show the new reference point between two adjacent PDSNs.

7 4.1 Network Reference Models

8 Figure 1 shows a reference model for Simple IP service with fast handoff.

9 Figure 2 shows a reference model for MIP service with fast handoff. For Internet access when 10 the MS is in the home network or roaming, the HA resides in a home access provider network. 11 For private network or home ISP access, the HA resides in the respective external network.

12 The IP Network entity in Figure 1 and represents IP Networks that may reside in the public 13 Internet as well as private IP networks between access provider networks and home IP networks.

3 The MS is implemented as a single MT0 type device or as a MT2 and a TE2 pair. See [11] for 4 details.

5 Although MIP and Simple IP services are represented in different protocol reference models, the 6 network provides both Simple IP and MIP service simultaneously to an MS using the same PPP 7 session. The network supports IPv4 and IPv6 MSs simultaneously. The network provides 8 Simple IPv4, Simple IPv6, MIP4, and MIP6 service for the same MS over the same PPP session. 9 Support of IPv6 MSs in the network is independent of the IP version used for transport in the 10 RAN.

11 4.2 Simple IP

12 Figure 3 shows the protocol reference model for Simple IPv4 or IPv6 service. Figure 4 shows the 13 protocol reference model for Simple IP access during fast handoff.

10 Figure 17 shows the protocol reference model for the RADIUS entities in the wireless network (as 11 illustrated in Figure 1 and Figure 2) between the PDSN (RADIUS client) and the Home RADIUS 12 server. In this model, the RADIUS servers in the visited network communicate with the RADIUS 13 servers in the home network via zero or more optional proxy (or Broker) RADIUS servers.

14 A RADIUS server may run IPv4, IPv6, or both. The method of inter-working between IPv4 and 15 IPv6 RADIUS clients and servers is outside the scope of this document.
