Description: ，人们提出了“服务质量”（Quality of Service，简称Q o S）
的概念。Q o S实际是一系列组件，允许对网上的数据进行不同处理，并可为其分配不同的优
先级。若一个网络具备Q o S功能，便可根据实际需要，对其进行配置-People put forward the quality of service (Quality of Service, referred to as Q o S) concept. Q o S is actually a series of components, allow for online data of different treatments, and its distribution of different priority. If a network with Q o S function can be based on actual needs, their configuration Platform: |

Description: H.323最新完全版的源代码,包括例程说明.
为了能在不保证QoS的分组交换网络上展开多媒体会议，由ITU的第15研究组SG-15于1996年通过H.323建议的第一版，并在1998年提出了H.323的第二版。H.323制定了无QoS（服务质量）保证的分组网络PBN（packet Based Networks）上的多媒体通信系统标准，这些分组网络主宰了当今的桌面网络系统，包括基于TCP/IP、IPX分组交换的以太网、快速以太网、令牌网、FDDI技术。因此，H.323标准为LAN、WAN、Internet、因特网上的多媒体通信应用提供了技术基础和保障。-H.323 completely up-to-date version of the source code, including the routine description. To be able to not guarantee QoS in the packet switching network, multimedia conferencing launched by ITU Study Group 15 of the first SG-15 in 1996 proposed the adoption of H.323 The first edition, and in 1998 the second edition of the H.323. H.323 developed a non-QoS (quality of service) guarantees packet networks PBN (packet Based Networks) on the multimedia communication system standards, these packet networks is the key to today s desktop systems, including those based on TCP/IP, IPX Packet exchange of Ethernet, Fast Ethernet, Token Ring, FDDI technology. Therefore, H.323 standard for LAN, WAN, Internet, Internet-based multimedia communications applications to provide the technical foundation and protection. Platform: |

Description: —One of themajor challenges in supportingmultimedia
services over Internet protocol (IP)-based code-division mul-
tiple-access (CDMA) wireless networks is the quality-of-service
(QoS) provisioning with effi cient resource utilization. Compared
with the circuit-switched voice service in the second-generation
CDMA systems (i.e., IS-95), heterogeneous multimedia applica-
tions in future IP-based CDMA networks require more complex
QoS provisioning and more sophisticated management of the
scarce radio resources. This paper provides an overview of the
CDMA-related QoS provisioning techniques in the avenues of
packet scheduling, power allocation, and network coordination,
summarizes state-of-the-art research results, and identifi es further
research issues. Platform: |

Description: In this letter, the performance of non-orthogonal multiple access (NOMA) is investigated in a cellular downlink scenario
with randomly deployed users. The developed analytical results
show that NOMA can achieve superior performance in terms of
ergodic sum rates; however, the outage performance of NOMA depends critically on the choices of the users’ targeted data rates and
allocated power. In particular, a wrong choice of the targeted data
rates and allocated power can lead to a situation in which the user’s
outage probability is always one, i.e. the user’s targeted quality of
service will never be met Platform: |
