HSDPAHSUPA+for+UMTS+High+Speed+Radio+Access

The first Third Generation Partnership Project (3GPP) Wideband Code Division Multiple Access (WCDMA) networks were launched during 2002. By the end of 2005 there were 100 open WCDMA networks and a total of over 150 operators having frequency licenses for WCDMA operation. Currently, the WCDMA network ...

MIMO-OFDM Wireless Communications with MATLAB

MIMO-OFDM is a key technology for next-generation cellular communications (3GPP-LTE, Mobile WiMAX, IMT-Advanced) as well as wireless LAN (IEEE 802.11a, IEEE 802.11n), wireless PAN (MB-OFDM), and broadcasting (DAB, DVB, DMB). This book provides a comprehensive introduction to the basic theory and pra ...

Radio+Resource+Management+Strategies

It is more than a decade since GSM was first commercially available. After some unexpected delay, it seems that finally UMTS is here to stay as a 3G system standardised by 3GPP, at least for another ten years. UMTS will enable multi-service, multi-rate and flexible IP native-based mobile technologie ...

SAE and the Evolved Packet Core

The outcome of the 3GPP SAE (system architecture evolution) technical study and specification work is a set of standards that specifies the evolution of the packet core network for GSM/GPRS and WCDMA/HSPA to an all-IP architec- ture and enables a feature-rich ‘common packet core’ for radio accesse ...

The 3G IP Multimedia Subsystem (IMS)

When 3GPP started standardizing the IMS a few years ago, most analysts expected the number of IMS deploymentsto grow dramatically as soon the initial IMS specifications were ready (3GPP Release 5 was functionallyfrozenin the first half of 2002and completedshortly after that). While those predictions ...

SIP协议介绍(RFC3261)

SP协议最早由是由 MMUSIC ETI工作组在1995年研究的，由T组织在1999年提议成为的一个标准。SP主要借鉴了Web网的HTP和SMTP两个协议3GPPR5/R6的MS子系统采用SP。3GPP制定的MS子系统相关规范推动了SP的发展。lETF提出的P电话信令协议基于文本的应用层控制协议独立于底层协议，可以使用TCP或UDP传输协议用于建立、修改和终止一个 ...
