SIST ES 283 018 V2.3.0:2008 is the Slovene adoption of ETSI ES 283 018 V2.3.0, a profile of H.248.1 for controlling Border Gateway Functions (BGF) in the Resource and Admission Control Subsystem (RACS). It specifies the Ia reference point between the Service Policy Decision Function (SPDF) and the BGF, so implementers know how the controller and gateway exchange commands for gates, address translation, bandwidth control, statistics, and recovery. The profile is Version 2 and is intended to remain backwards compatible with Version 1.
What does SIST ES 283 018 V2.3.0:2008 specify?
SIST ES 283 018 V2.3.0:2008 specifies how the Gateway Control Protocol (H.248.1) is profiled for Border Gateway Functions (BGF) on the Ia reference point. The standard is written for the interaction between SPDF and BGF in TISPAN RACS and is aligned with the BGF roles used in Core-BGF and Interconnect-BGF deployments.
The document is organized into the scope, references, definitions, applicability, and a detailed profile description. Its main body covers the connection model, terminations, descriptors, commands, transport, security, packages, SDP usage, and both session-dependent and session-independent procedures. Informative annexes add comparisons, examples, and mapping guidance.
| Annex | What it covers |
|---|---|
| Annex A | General notes and the relationship between gates and H.248 streams |
| Annex B | Comparison between Ia Profile Version 1 and TS 102 333 (GCP) |
| Annex C | Comparison between Ia Profile Version 1 and the Version 2 profile |
| Annex D | Example IP processing model for an H.248 (IP, IP) context |
| Annex E | Guidelines for Ia-to-Gq' mapping |
What are the key requirements of SIST ES 283 018 V2.3.0:2008?
SIST ES 283 018 V2.3.0:2008 defines a constrained H.248 profile for point-to-point IP-to-IP control. In practice, the standard narrows the protocol to the BGF use case so that both ends of the control relationship know which commands, descriptors, packages, and media descriptions they can rely on.
Protocol version and connection model
Clause 5.3 requires ITU-T Recommendation H.248.1 Version 3. That matters because the profile uses features such as stream statistics.
Clause 5.4 limits the connection model to provisioned contexts, a maximum of two terminations per context, and the allowed termination combination (IP, IP). For implementers, this means the profile is aimed at single IP-to-IP flows rather than richer media gateway topologies.
Clause 5.5 only supports the Priority Indicator and Emergency Indicator among the listed context attributes. If you are configuring or auditing a BGF, these are the context-level controls the profile expects you to use.
Termination naming and descriptor use
Clause 5.6.1.1 defines the IP termination name as ip/group/interface/id. The Group is an integer from 0 to 255, the Interface is a string, and the Id is a non-zero 32-bit integer. The standard also allows CHOOSE wildcarding for the Interface and requires CHOOSE wildcarding for Id in the ADD.request command, which gives the MG room to allocate local resources while still letting the MGC manage context structure.
Clause 5.7 and the descriptor tables define which H.248 descriptors are used in this profile and how they behave. For example, the profile does not use event buffering or signals as general media features, so implementations stay focused on gate control, reporting, and stream handling rather than telephony-style signal control.
Commands, encoding, transactions, and transport
Clause 5.8 restricts the command set to the commands that matter here: Add, AuditValue, Modify, Notify, ServiceChange, and Subtract. Clause 5.10 limits a transaction message to one request/reply/ack segment group per message and allows up to two commands per transaction request or reply. In practice, this keeps message exchanges small and predictable for control-plane implementations.
Clause 5.9 allows text encoding only and requires the receiver to accept both Short Token Notation and Long Token Notation. Clause 5.12 makes SCTP the recommended transport and UDP optional. For UDP, segmentation depends on the Segmentation package, while SCTP provides segmentation inherently. Clause 5.13 states that no security is supported at this profile level, so deployments must address security elsewhere if they need it.
SDP and package behavior
Clauses 5.15 and 5.16 define how SDP is used. The profile requires core SDP items such as v=0, c=IN with IP4 or IP6, m= lines, and b=AS bandwidth signaling. Optional SDP items such as o=, s=, and t= are also described. For readers, this means the MGC and MG must exchange a controlled subset of SDP elements and use them consistently when establishing or updating streams.
Clause 5.14 groups the supported H.248 packages. The mandatory and optional packages cover gate management, network functions, differentiated services, traffic management, NAPT traversal, MPLS, VLAN, MGC information, inactivity, segmentation, RTP support, application data inactivity detection, IP domain connection, overload control, hanging termination detection, and statistic conditional reporting. The practical effect is that the profile can support NAT traversal, QoS marking, bandwidth control, inactivity detection, and statistics, but only through the named packages and their described usage.
Session-dependent and session-independent procedures
Clause 5.17 and clause 5.18 describe the main session procedures. Gate opening and closing are done by stream mode changes, and subtracting a termination closes the gate for its H.248 streams. Address filtering may be handled either through the Gate Management package or through the Remote Descriptor, with the package overriding MG configuration when used. The profile also covers NAPT-PT, Hosted NAT Traversal, QoS marking, bandwidth reservation and policing, RTCP handling, media inactivity, realm/domain indication, two-stage BGF resource reservation, hanging termination detection, real-time statistics reporting, and transcoding.
Clause 5.18 also shows concrete message patterns for add, update, modify, audit, notify, and subtract flows. That is important because it tells implementers which information belongs in the ADD, which events are reported by NOTIFY, and how to request or return statistics during a call or session change.
Clauses 5.19 and 5.20 define the non-session-related and session-independent procedures. These include MG registration and restoration, context audit, out-of-service handling, control-association recovery, overload notification, handoff, failover, and user plane failure reporting. For operators, these procedures are the life-cycle tools for startup, maintenance, fault handling, and re-synchronization.
What terms does SIST ES 283 018 V2.3.0:2008 define?
- BGF - A packet-to-packet gateway for user-plane media traffic that performs policy enforcement and NA(P)T functions under SPDF control.
- GATE - A transport-plane function that enables or disables unidirectional forwarding of IP packets under specified conditions such as QoS.
- RACS - The Resource and Admission Control Subsystem that coordinates admission and resource control for the NGN environment.
- SPDF - The Service Policy Decision Function that interacts with the BGF at the Ia reference point and requests services.
- MGC - The Media Gateway Controller, which controls the MG side of the H.248 association.
- MG - The Media Gateway role used by the BGF in this profile.
- NAPT-PT - Network Address and Port Translation and Protocol Translation, used here for IPv4/IPv6 interworking.
- CoAC and StAC - Context Admission Control and Stream Admission Control, the admission-control behaviors used on the MG side.
Who uses SIST ES 283 018 V2.3.0:2008?
SIST ES 283 018 V2.3.0:2008 is used by telecom engineers, NGN architects, gateway vendors, and service providers working on RACS-controlled IP transport networks. It is especially relevant where an SPDF controls a BGF for access/core or interconnect use.
Quality teams and integrators use the standard when they need to verify registration, auditing, NAT traversal, bandwidth reservation, statistics reporting, overload handling, and failover behavior. Buyers and solution evaluators use it to check whether a product supports the H.248 profile expected at the Ia reference point.
What changed in SIST ES 283 018 V2.3.0:2008 from the previous edition?
SIST ES 283 018 V2.3.0:2008 introduces a new Version 2 of the Ia profile for NGN Release 2 requirements while keeping backwards compatibility with Version 1. The standard also states that Version 2 includes improvements that clarify usage within NGN Release 1.
Annex C compares Version 1 with Version 2, and the stated changes include basic QoS monitoring support through H.248 statistics, guidance on SDP usage, and the Version 2 termination structure ip/group/interface/id.

1 Scope
The present document defines a profile of the Gateway Control Protocol (H.248.1) to be used for controlling Border
Gateway Functions (BGF), as defined in ES 282 003 [3].
2 References
References are either specific (identified by date of publication and/or edition number or version number) or
non-specific.
• For a specific reference, subsequent revisions do not apply.
• Non-specific reference may be made only to a complete document or a part thereof and only in the following
cases:
- if it is accepted that it will be possible to use all future changes of the referenced document for the
purposes of the referring document;
- for informative references.
Referenced documents which are not found to be publicly available in the expected location might be found at
http://docbox.etsi.org/Reference.
For online referenced documents, information sufficient to identify and locate the source shall be provided. Preferably,
the primary source of the referenced document should be cited, in order to ensure traceability. Furthermore, the
reference should, as far as possible, remain valid for the expected life of the document. The reference shall include the
method of access to the referenced document and the full network address, with the same punctuation and use of upper
case and lower case letters.
NOTE: While any hyperlinks included in this clause were valid at the time of publication ETSI cannot guarantee
their long term validity.
