The merging of voice and knowledge on a unmarried community opens strong new chances in communications. just a basic figuring out of either applied sciences will make sure you are outfitted to maximize their complete potential.
Convergence applied sciences for 3G Networks describes the evolution from mobile to a converged community that integrates conventional telecommunications and the know-how of the Internet. specifically, the authors tackle the appliance of either IP and ATM applied sciences to a mobile setting, together with IP telephony protocols, using ATM/AAL2 and the hot AAL2 signalling protocol for voice/multimedia and information delivery in addition to the way forward for the UMTS community in UMTS unencumber 5/6 All-IP structure.
Convergence applied sciences for 3G Networks :
- Explains the operation and integration of GSM, GPRS, part, UMTS, CDMA2000, IP, and ATM.
- Provides functional examples of 3G connection situations.
- Describes signalling flows and protocol stacks.
- Covers IP and ATM as utilized in a 3G context.
- Addresses problems with QoS and real-time program help.
- Includes IP/SS7 internetworking and IP softswitching.
- Outlines the structure of the IP Multimedia Subsystem (IMS) for UMTS.
Convergence applied sciences for 3G Networks is fitted to execs from the telecommunications, facts communications and laptop networking industries..

It links what has gone before in GSM and GPRS with the new radio access network that forms the basis of the UMTS network. The chapter focuses on the operation of the ﬁrst release of UMTS, Release 99, but explains the changes to this network as it evolves to an all-IP infrastructure. The operation of signalling protocols throughout the network is described in signiﬁcant detail. A basic overview of the operation of the CDMA2000 system is also presented for reference. Chapter 7 explains the application of ATM technology as a transport layer within the UMTS radio access network.
The protocol which provides CoS on IP networks is called DiffServ. RSVP and DiffServ are presented in Chapter 5 while QoS in the context of ATM is explained in Chapter 7. 4 MULTIPLE ACCESS In any communications system with many users, whether it be a ﬁxed line or a wireless scheme, those users share some resource. Some mechanism must be employed to enable this resource sharing, and this is referred to as a multiple access scheme. In the wireless domain, the resource that is shared is frequency.
With IP, the QoS solutions must be incorporated into the protocol suite. There are two basic approaches to provide trafﬁc with QoS: guaranteed QoS and class of service (CoS). With guaranteed QoS, the network is expected to provide a minimum service deﬁned by a set of quality parameters, including such things as minimum and average data rates, maximum delay and jitter as well as maximum packet loss rate. This type of service requires that the network has had some resources dedicated for the duration of the data transfer.
