  • This brief guide aims at explaining the basic steps for getting started with GPRS. It supposes you are a bit familiar with GPRS concepts, like network attachment, session or PDP context. This guide is not intended to give full details about how GPRS works, all GPRS-specific AT commands (check out the GPRS AT command manual). By default depending on the firmware version, the MS starts up either in class CG (i.e. in GPRS mode and not in GSM mode) or in class B.

  • Mobility is the key to the success of wireless networks. Roaming has extended the definition of mobility beyond the technology, network, and country boundaries. Is not it fascinating to make or receive calls anywhere in the world using the same phone and identity? International roaming is already proven to be one of the most popular features of today’s wireless network. With the advent and widespread deployment of GSM technology, the mobile users have flexibility to use services in more than 500 networks. Inter-standard roaming has also made significant progress in recent years.

  • GSM

    GSM (Global System for Mobile Communications), is a standard set developed by the European Telecommunications Standards Institute (ETSI) to describe technologies for second generation digital cellular networks. Developed as a replacement for first generation analog cellular networks, the GSM standard originally described a digital, circuit switched network optimized for full duplex voice telephony. The standard was expanded over time to include first circuit switched data transport, then packet data transport via GPRS (General Packet Radio Services)....

  • Wireless and Mobile Internet have changed the way people and businesses operate. Communication from any Internet access point, including wireless networks such as UMTS, GPRS or WLAN has enabled organizations to have a mobile workforce. However, networked applications such as web, email, streaming multimedia etc. rely upon the ability of timely data delivery. The achievable throughput is a quality measure for the very task of a communication system, which is to transport data in time. Throughput is thus one of the most essential enablers for networked applications.

  • Having dealt with in-depth analysis of SS#7, GSM and GPRS networks I started to monitor UTRAN interfaces approximately four years ago. Monitoring interfaces means decoding the data captured on the links and analysing how the different data segments and messages are related to each other. In general I wanted to trace all messages belonging to a single call to prove if the network elements and protocol entities involved worked fine or if there had been failures or if any kind of suspicious events had influenced the normal call proceeding or the call’s quality of service.

  • Handoff in mobile and wireless networks Wireless data services use small-coverage high-bandwidth data networks such as IEEE 802.11 whenever they are available and switch to an overlay service such as the General Packet Radio Service (GPRS) network with low bandwidth when the coverage of a Wireless Local Area Network (WLAN) is not available. From the service point of view, Asynchronous Transfer Mode (ATM) combines both the data and multimedia information into the wired networks while scaling well from backbones to the customer premises networks....

  • GSM (Global System for Mobile Communications, originally Groupe Spécial Mobile), is a standard set developed by the European Telecommunications Standards Institute (ETSI) to describe technologies for second generation (2G) digital cellular networks. Developed as a replacement for first generation (1G) analog cellular networks, the GSM standard originally described a digital, circuit switched network optimized for full duplex voice telephony.

  • With SMS, several modes are possible for addressing message recipients. The most common addressing mode consists of using the Mobile Station ISDN Number (MSISDN) in the [ITU-E.164] format (e.g., þ33612345678). However, other less commonly used addressing modes are available such as Email addressing, as defined by the IETF in [RFC-2822], or operator specific numbering schemes (short codes for instance). An optional addressing feature of SMS consists of conveying sub-addressing information as part of a message.

  • SIP’s popularity has grown enormously over the past few years. A big boost in support came in November 2000, with the acceptance of SIP by the 3rd Generation Partnership Project (3GPP). 3GPP is composed of standards organizations in China, Europe, Japan, North America and South Korea, and is dedicated to the proliferation of a third-generation wireless global standard. More specifically, this organization focuses on the development of standards for the Universal Mobile Telecommunications System (UMTS).

  • General Packet Radio Service (GPRS) Packet data transmission has already been standardized in GSM phase 2, offering access to the Packet Switched Public Data Network (PSPDN); see Sections 9.5.3 and 9.6.2. However, on the air interface such access occupies a complete circuit switched traf®c channel for the entire call period. In case of bursty traf®c (e.g. Internet traf®c), such access leads to a highly inef®cient resource utilization. It is obvious that in this case, packet switched bearer services result in a much better utilization of the traf®c channels.
