SIST-V ETSI/EG 201 718-1 V1.1.2:2003

• Abstract:

  This work item identifies the protocol requirementsto provide third generation mobility management capabilities in evolved fixed networks. The requirements will be used by protocol experts to define the adequate protocols for the evolution from fixed networks toward IMT-2000 core networks. The first deliverable addresses mobility management requirements for the first phase of UMTS as defined by SMG. Tha main constraint of this document is the very tight schedule for UMTS phase 1.

SIST-V ETSI/EG 201 718-1 V1.1.2:2003 is the SIST publication of an ETSI Guide on Universal Mobile Telecommunications System (UMTS) mobility management for evolved fixed networks, Part 1: Phase 1. It specifies protocol requirements for third generation mobility management in fixed, cordless and private access scenarios, for protocol experts who are defining internetwork signalling on the path from fixed networks toward IMT-2000 core networks.

What does SIST-V ETSI/EG 201 718-1 V1.1.2:2003 specify?

SIST-V ETSI/EG 201 718-1 V1.1.2:2003 defines the protocol requirements needed for UMTS Phase 1 mobility management in evolved fixed networks. It focuses on how UMTS requirements can be applied when fixed networks evolve toward UMTS, including cordless and fixed access and access from private networks.

The document is organized into scope, references, definitions and abbreviations, architecture principles, parameters relevant for mobility management, description of mobility procedures, bibliography and history. The foreword also places it in a multi-part EG covering UMTS mobility management for evolved fixed networks.

What are the key requirements of SIST-V ETSI/EG 201 718-1 V1.1.2:2003?

• Clause 4 introduces additional reference points for fixed and cordless access. Table 1 shows how Uu, Iu, Zu and Wu are used across cellular, private access, private network and public access scenarios. In practice, this matters because wired and private-access implementations need a Wu interface and must account for the impact on Iu.

• Clause 5 identifies the main mobility-related identities: IMEI, IMUI, MSISDN, TMUI and MSRN, plus network element addresses. In practice, protocol messages and databases must carry these identities correctly so the network can recognize the terminal, subscriber and routing information.

• Clause 6.1 lists the basic mobility management procedures: location registration/update, location cancellation, routeing information retrieval and authentication information retrieval. It also notes service profile transfer and per-call retrieval of subscriber profile elements as related functions tied to VHE. For implementers, these are the exchanges that support roaming and subscriber continuity.

• Clause 6.2.1 covers roaming within one public network using public access systems. The MSISDN follows ITU-T Recommendation E.164 and the public network numbering plan, and the IMUI identifies the home public network. In practice, this is the simplest registration case, with standardization mainly needed between the terminal and the access network.

• Clause 6.2.2 covers roaming between public networks using public access systems. The text bases Phase 1 roaming on bilateral roaming agreements and says the registration message flow must be harmonized across UMTS family members. It also ties fixed-network evolved UMTS to ETS 300 557, ETS 300 359, ETS 300 974 and ETS 300 605, and notes that packet-switched services require GPRS specifications.

• Clauses 6.2.3 and 6.3 extend the same model to other roaming scenarios and classify the procedures into location management, routeing data management and authentication. The document says state-machine techniques from IN and second generation mobile systems can be applied, which helps protocol designers model the signalling consistently.

What terms does SIST-V ETSI/EG 201 718-1 V1.1.2:2003 define?

• Private access system: an access system owned and operated by the customer, located on the customer premises and connected to a public network.
• Private network: a self-contained customer-owned network on the customer premises that may interwork with other private or public core networks.
• International Mobile User Identity (IMUI): the user identity used in the document to identify the home public network or subscription.
• Temporary Mobile User Identity (TMUI): the temporary identity used on the radio interface instead of the IMUI.
• Home Location Register (HLR): the home-network database that supports location and subscriber-related mobility handling.
• Visited Location Register (VLR): the visited-network database that stores location information for roaming support.

Who uses SIST-V ETSI/EG 201 718-1 V1.1.2:2003?

SIST-V ETSI/EG 201 718-1 V1.1.2:2003 is aimed at protocol experts, UMTS network architects, and engineers working on the evolution from fixed networks toward UMTS. It is also relevant to operators and implementers who need to design roaming, interworking, location registration and authentication across public, private, wired and cordless access scenarios.

Which standards are used with SIST-V ETSI/EG 201 718-1 V1.1.2:2003?

• TS 23.101 - provides the general UMTS architecture and the Uu and Iu reference points.
• TR 23.930 - provides the Iu principles.
• ITU-T Recommendation E.164 - provides the international public telecommunication numbering plan used for MSISDN.
• ETS 300 557 - provides GSM layer 3 call control and mobility management on the UNI.
• ETS 300 359 - provides the MSC-BSS layer 3 interface specification.
• ETS 300 974 - provides the Mobile Application Part (MAP) specification.
• ETS 300 605 - provides information element mapping between MS-BSS/BSS-MSC signalling and MAP.
• EG NA 061301, Q.1701, Q.1711 and Q.1751 - are cited in the scope as reference documents for the IMT-2000 and UMTS evolution context.

What does the SIST-V ETSI/EG 201 718-1 V1.1.2:2003 document contain?

The document contains architecture principles, identity lists, roaming scenarios and signalling flow diagrams for mobility management. Table 1 maps interface use across access scenarios, Table 2 lists the identities relevant to UMTS phase 1, and Tables 3 and 4 describe the location registration message flows.

Figures 2 to 7 illustrate roaming within one public network, roaming between public networks and the internetworking architecture between UMTS networks. Clause 6.3 then groups the procedures by function, which makes the document useful for protocol design and for checking how location update, routeing and authentication are meant to fit together.

Foreword
This ETSI Guide (EG) has been produced by ETSI Technical Committee Services and Protocols for Advanced
Networks (SPAN).
The present document is part 1 of a multi-part EG covering the Universal Mobile Telecommunication Service (UMTS);
Mobility Management for evolved fixed networks, as identified below:
Part 1: "Phase 1";
Part 2: "Phase 2".
Introduction
UMTS is the European standard within the IMT2000 framework. UMTS will specify an IMT2000 system which will be
compatible with and use the IMT2000 standards to support the evolving services. It is therefore essential that the
features and the requirements identified for UMTS are related to the IMT2000 requirements.
Backward compatibility is a prerequisite of UMTS phase 1. It is expected that the transition from existing networks to
UMTS phase 1 will be as soft as possible. As a consequence, the protocol requirements work specified in the present
document, as well as the definition of protocols derived from it, should carefully consider the evolution from existing
mobility management protocols.

1 Scope
The present document defines the protocol requirements needed to provide third generation mobility management
capabilities in evolved fixed networks.
The present document focuses on the protocol requirements for the first phase of UMTS as defined by 3GPP.
3GPP defines G-UMTS based on GSM evolution. The present document studies how these 3GPP requirements can be
applied to the evolution from fixed networks towards UMTS.
In particular, the present document will address the case of cordless and fixed access to UMTS, including access from
private networks.
