Convergence Technologies for 3G Networks: IP, UMTS, EGPRS by Jeffrey Bannister

By Jeffrey Bannister

The merging of voice and knowledge on a unmarried community opens robust new percentages in communications. just a primary realizing 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 expertise of the Internet.  specifically, the authors handle the appliance of either IP and ATM applied sciences to a mobile atmosphere, together with IP telephony protocols, using ATM/AAL2 and the hot AAL2 signalling protocol for voice/multimedia and knowledge 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 sensible examples of 3G connection eventualities.
  • Describes signalling flows and protocol stacks.
  • Covers IP and ATM as utilized in a 3G context.
  • Addresses problems with QoS and real-time software 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 pros from the telecommunications, info communications and computing device networking industries..

Cognitive Radio Technology

Cognitive radio know-how is a better, swifter, and extra effective strategy to transmit details to and from mounted, cellular, different instant verbal exchange units. Cognitive radio builds upon software-defined radio expertise. A cognitive radio method is 'aware' of its working setting and immediately adjusts itself to keep up wanted communications-it's like having a proficient operator 'inside' the radio making consistent changes for optimum functionality.

Example text

Chapter 8 discusses the use of IP in UMTS as the network evolves to Release 4. In Release 4, the traditional circuit switched core network infrastructure of GSM is replaced with an IP-based softswitch architecture. This chapter explains the operation of new protocols to support this architecture, where the role of the mobile switching centre (MSC) is split into control using an MSC server and traffic transfer with a media gateway (MGW). The real-time extensions to IP for support of voice transport, the real-time transport protocol and the real-time transport control protocol (RTP/RTCP), are covered here.

1. This implies that the important factor that will affect how easily signals can be interpreted after they are despread is the power level in the system. The lower the power that the original signals are transmitted with, the lower the noise in the system. It is therefore essential that each user in the system transmits with an optimum power level to reach the receiver with its required power level. If the power level is too high, then that user will generate noise, which in turn affects the performance of all the other users.

If a wideband signal is affected by a narrowband noise signal, then since the spreading function is commutative, the despreading operation while extracting the wanted signal will in turn spread the narrowband noise to the wideband, and reduce its power level. 1. This implies that the important factor that will affect how easily signals can be interpreted after they are despread is the power level in the system. The lower the power that the original signals are transmitted with, the lower the noise in the system.
