5.17.1.10 IP Realm/Domain Indication
1e3c7e6a783f798e804b24eccd66846f
183 018
5.17.1.10.1 Codepoint and format/encoding
The IP realm identifier (i.e. H.248 property ipdc/realm) may be sent to the BGF in order to indicate the IP domain/realm of the H.248 IP termination. The IP realm identifier is a flexible string and may convey a numerical IP address, domain name or mutually understood name (e.g. "in"and "out", "1" and "2", etc.) (see n...

5.17.1.10.2 Unsuccessful indication
If the value of the IP realm identifier sent by the MGC within the ITU-T Recommendation H.248.41 [16] package property cannot be recognized by the BGF, the BGF will fail to create the IP based H.248 termination and replies with an error descriptor using the error code 449 (Unsupported or Unknown Parameter or Property V...

5.17.1.10.3 Fix assignment per termination lifetime
The MGC may or may not choose to assign IP realm identifier when communicating with the MG e.g. not sent if IP Realm configured on the MG. If the MGC assigns IP Realm then this must be communicated at termination seizure (Add). The value of IP Realm shall be applied to all streams associated with the termination. The I...

5.17.1.10.4 Number of IP Realms/Domains
The BGF supports typically multiple logical IP interfaces, which may belong to different IP address realms. Following principal use cases may be distinguished: 1) Single realm: - All IP interfaces of the BGF, and therefore all created H.248 IP terminations, belong to the same IP address space. 2) Multiple realms (N pri...

5.17.1.11 One-Stage and Two-Stage BGF Resource Reservation
The SDP offer/answer model (RFC 3264 [7]) allows offers and answers to be generated with or without "m=" and "b=" lines. The normal case is when both information contained in SDP "c=" and "m=" lines is available to the MGC at the time it requests the MG to create a termination is referred to as one-stage reservation.

5.17.1.12 Hanging Termination Detection
For the correct operation of a BGF, synchronization of termination information between the SPDF and BGF is essential for traffic, maintenance and charging purposes. In some cases, the SPDF may have lost a record of a termination but the termination is not subtracted on BGF. The hangterm/ thb event defined in ITU-T Reco...

5.17.1.13.1 Overview of conditional reporting
Normally a SPDF obtains bearer related statistics through periodic auditing of the H.248 statistic descriptor or at the time of deletion of a stream or subtraction of a termination. However, in both cases, there is a time delay from when a reporting condition occurs on a BGF (e.g. a statistic threshold being passed) an...

Topology hiding may basically be related to the: a) hiding of "remote topology information", i.e. the BGF provides local support for topology hiding to network elements "behind" the BGF; b) hiding of "local topology information", i.e. the BGF provides local support for topology hiding of the BGF itself in one-way direc...
