Book Description
GPRS is a packet based wireless communication service that offers data rates from 9.05 up to 171.2 Kbps and continuous connection to the Internet for mobile phone and computer users. GPRS is based on GSM communications and complements existing services such as circuit switched cellular phone connections and the Short Message Service (SMS). GPRS represents the bridge between 2G and 3G mobile telecommunications and is commonly referred to as 2.5G. Implementation of GPRS requires modification of the existing GSM networks in that GSM is a circuit switched technology while GPRS is packet oriented. GPRS enables packet data (the same as is used by an Ethernet LAN, WAN or the Internet) to be sent to and from a mobile station - e.g. mobile phone, PDA or Laptop. WAP and SMS can also be sent using GPRS and individuals working with GPRS need to learn and understand how the mobile stations, the air interface, network architecture, protocol structures and signalling procedures must be modified. GPRS offers much higher data rates than GSM and can be combined with 3G technologies such as EDGE to give even higher bit-rates. It offers many benefits for customers and network operators: such as volume (rather then time) dependent billing and more efficient use of network resources. Due to the worldwide delay in implementing 3G solutions such as CDMA and UMTS the demand for GPRS is still growing. GPRS Networks: Offers detailed information ranging from standards to practical implementation Answers 'how' and 'why' rather than just simply re-stating GPRS specifications Provides comprehensive coverage in a single volume Essential reading for all telecommunications project managers, field engineers, technical staff in network operator and manufacturing organisations, GPRS application and service developers, Datacoms/IT engineers. The comprehensive coverage also makes this a superb reference for students of computer science, telecommunications and electrical engineering.

Book Description
Professionals quickly discover that, although the technical specifications for GPRS cover all parts of the engineering functions in detail and depth, they are lacking in one important feature; the conceptual framework within which the specifications sit - GPRS in Practice fills this gap. By beginning with an explanation of why GPRS is necessary and describing the core concept of GPRS operations, the TBF (Temporary Block Flow), a revision section then covers the GSM Air Interface with its Radio, Physical and Logical channels and this progressively leads to the GPRS logical channels - what they do and how they do it. The book then moves on to a brief introduction of the GPRS protocol stack which provides a launch pad for a detailed trip into all the layers of this stack, with detailed diagrams and explanations of each layer integrated into an overall understanding of how the GPRS service operates in practice. Provides descriptions of why procedures are specified and then clearly explains how the specifications work in practice Provides a layered view of the GPRS protocol and deals in detail with each layer separately Includes numerous acronyms and abbreviations accompanied by their full meaning An invaluable resource for Mobile network operators, Development and deployment engineers and Handset designers.

Book Description
New, attractive services for communications systems are versatile and promise to make the next generation of communications a success. Yet, as the systems grow more complex and diverse, so do the challenges of managing them. Service management derives from technologies used in fixed telephony systems and has evolved towards supporting packet-based services in an increasingly open environment. It is common belief that 3G (and later 4G) services will change the way we communicate and interrelate. The user will be put at centre stage and systems will be able to handle intelligent user profiles, proactive service selection, context-aware service provisioning and ubiquitous computing. Managing, charging for, and controlling these services render traditional business models inadequate and demand new solutions. Managing Mobile Services Covers challenges, solutions and technologies for implementing IP-based services in a mobile environment, with special attention to security, flexibility and charging. Discusses business models, service management architectures and standardization efforts. Considers requirements and characteristics of services, and service modelling. Includes two case studies illustrating the challenges, technologies and solutions involved with real-world service management. This book gives telecommunications/data engineers, operators and service providers as well as students and academics an in-depth understanding of the issues involved in implementing and managing new value-added services.
