ITU-T H.248.1定义了国际紧急优先方案(IEPS)呼叫指示符和优先级指示符,以支持优先服务,例如紧急电信服务(ETS)和多媒体优先服务(MPS)。使用IEPS呼叫指示符和优先级指示符,如ITU-T H.248.1所定义,满足ETS的要求,指示ETS上下文并携带优先级。 在媒体网关控制器(MGC)中对ITU-T H.248程序的优先级排序以及向媒体网关(MG)传输ITU-T H.248控制信号是基于ETS的识别。 IEPS呼叫指示符,识别ETS呼叫/会话,向MG指示上下文是ETS上下文,并在接收后启用ITU-T H.248控制信号的优先级排序。此外,它使MG能够优先分配ETS上下文的资源。 携带优先级的优先级指示符为MG提供了一种手段,以区分在ETS使用时MG资源的不同优先级处理。 本建议提供了在ITU-T H.248配置文件中使用IEPS呼叫指示符和优先级指示符的指南,适用于ITU-T H.323和NGN系统。这些指南可被其他标准开发组织(SDO)在定义其ITU-T H.248.1配置文件以支持优先服务(例如ETS和MPS)时使用。关于这些指南如何被其他网络使用的详细信息不在本建议的范围内。其他SDO在定义其配置文件时决定其使用。 ETS和IEPS分别在ITU-T E.107和ITU-T E.106中定义。ETS和IEPS涉及机构间通信。ITU-T H.248.1中定义的紧急指示符用于识别紧急呼叫(即个人与机构之间的通信)。IEPS呼叫指示符用于识别优先呼叫/会话(例如ETS呼叫/会话,IEPS呼叫/会话),允许与紧急呼叫/会话区分开来。紧急指示符的配置文件程序规范不在本建议的范围内。 国家监管机构可以以多种方式实施ETS。本建议描述了一种支持IEPS呼叫指示符和优先级指示符的实施方式。此外,它还描述了用于标记ETS呼叫/会话的DiffServ信号ITU-T H.248.52方法。 注1 - 国家、地区或地方的紧急和公共安全服务,其中公众个人寻求帮助(即个人与机构之间的通信),不在本建议的范围内。 注2 - [b-ITU-T Q-Sup.53]提供了支持IEPS的信号要求。它也适用于ITU-T H.248实体,但未指示除第7条之外的任何要求。 注3 - [b-ITU-T Q-Sup.57]提供了支持IP网络中ETS的信号要求。它也适用于ITU-T H.248实体,但未指示除第7条之外的任何要求。
DiffServ signalling approach
The aim of the present document is to define an open specification for enabling QoS for IP-based multimedia satellite systems, based on the DiffServ model. If IP packets entering the BSM network require a particular QoS treatment, they have to be mapped onto QIDs. The choice of the QID to be used inside the BSM network is thus particularly important. So the present document specifies the allocation of the QIDs and their mapping to IP QoS classes, when DiffServ is used to provide QoS at IP layer. The present document assumes the QoS functional architecture described in ETSI TS 102 462 [2]. The present document describes in detail how QIDs are defined, how they are allocated and handled by the BSM network, and the requirements needed by sending and receiving Satellite Terminals (STs) in a BSM network to provide QID management functionalities. The present document also defines the primitives that should be used across the SI-SAP when allocating QIDs, when mapping DiffServ Code Points (DSCPs) and IP services to QIDs, when mapping QIDs to SD queues. Details on the QID mapping are presented with some examples. Some cases are presented to show the potential evolution from a simple QoS solution with quasi-static QID allocation to more sophisticated services with dynamic resource reservation. The combination of DiffServ with multicast transmissions is out of scope of the present document, as well as the use of Explicit Congestion Notification (ECN), which was linked to DiffServ only for historical reasons, as the ECN bits are the two least significant bits of the IPv4 ToS octet. This is better explained in clause 4.

本文件旨在定义基于DiffServ模型的IP多媒体卫星系统QoS开放规范。当进入BSM网络的IP数据包需要特定QoS处理时,必须映射到QID。本文档详细说明了QID的定义、分配和处理方式,以及发送和接收卫星终端(ST)在BSM网络中提供QID管理功能的要求。文档还定义了在分配QID、映射DiffServ代码点(DSCP)和IP服务到QID、映射QID到SD队列时在SI-SAP上使用的原语。DiffServ与多播传输的组合以及显式拥塞通知(ECN)的使用不在本文档范围内。

Universal Mobile Telecommunications System (UMTS); LTE; IP Multimedia Subsystem (IMS) Application Level Gateway (IMS-ALG) – IMS Access Gateway (IMS-AGW) interface: Procedures descriptions (3GPP TS 23.334 version 9.1.0 Release 9)
Annex G of 3GPP TS 23.228 [2] gives out an IMS Application Level Gateway (IMS-ALG) and IMS Access Media Gateway (IMS-AGW) based reference model to support NAPT-PT, gate control and traffic policing between IP-CAN and IMS domain. Figure 1.1 illustrates the reference model for Iq: - the dashed line represents the IP signalling-path with SIP (at Gm) as call/session control protocol between the UE and the P-CSCF (IMS-ALG); - the bold, horizontal line represents the IP media-path (also known as (IP) bearer-path or (IP) data-path; the notion 'media' is used as generic term for "IP application data"); and - the vertical line represents the Iq control-path with H.248 as gateway/policy control protocol between the IMS-ALG and the IMS-AGW (H.248 messages are transported over IP). The Iq reference point is between the P-CSCF (IMS-ALG) and the IMS-AGW. It conveys the necessary information that is needed to allocate, modify and release (IP) transport addresses. The present document defines the stage 2 description for the Iq reference point. The stage 2 shall cover the information flow between the P-CSCF (IMS-ALG) and IMS-AGW. The protocol used over the Iq interface is the gateway control protocol according ITU-T Recommendation H.248 (which is specified for Iq by an H.248 profile according 3GPP TS 29.334 [3]).
