Wireless Communication Transfer Protocol. PCIA messaging protocol. standardfor message exchange between paging systems like TNPP but based on XML.
Simple Network Paging Protocol - Internet standard for communication between paging and messaging systems IETF RFC 1861 (Simple Network Paging Protocol - Version 3 - Two-Way Enhanced). SNPP supports two-way messaging but is also a way of wrapping-up TAP messages for transmission over the Internet.
Short Message Service, a GSM facility for sending up to 160 character messages between compatible devices. Equivalent teleservices called CMT, exist for North American IS-95 and IS-136 systems. More about SMS in the FBMC SMS Briefing. SMS is widely used as a marketing tool, companies will typically use a short code to provide easy MO (mobile originate) access and use an aggregator to handle the network relationship and specialised SMSC interconnect protocols such as SMPP, CIMD, OIS and UCP. SMS also provides an alert mechanism for voice messaging.
Internet Simple Mail Transfer Protocol. A protocol which describes MTA and UA actions of an email system. SMTP uses MIME to encode complex data for transmission. SMTP and MIME are used to transfer MMS (the mobile Multimedia Message Service) between MMS MTAs.
Telocator Network Paging Protocol - PCIA protocol for message exchange between paging systems.
Subscriber Identity Module. GSM smart card holding the user’s identity and telephone directory and SMS messages. Applications may also reside on the SIM using SIM Toolkit. Some IS-136 phones have a non-removable NAM (numbering and addressing module) which has a similar function but Third Generation systems are adopting a removable user (i.e. phone subscriber) identity such as the UMTS USIM.
The universal wired LAN standards and services based on ideas from the Aloha packet radio network. Defined by IEEE 802 series standards. Wireless LAN standards delivering equivalent services are defined by 802.11 standards
Telocator Alphanumeric Protocol, .
- Transferred Account Procedure, a billing record format used by GSM carriers to account for roaming users. A billing record format used by GSM carriers to exchange information about the activities of roamers. Developed by the GSM Association. The latest version, TAP3, supports billing of GPRS roamers
or Telocator Alphanumeric Protocol, a simple protocol for transmitting paging messages from PCs and other simple devices - and also for MT (mobile terminated) SMS and CMT messages. Standard protocol for simple alphanumeric input to paging systems, one way. The Telocator standards body is now PCIA (Personal Communications Industry Association).
Internet Transmission Control Protocol. The IPS connection-oriented Internet packet protocol which uses the IP connectionless lower layer (see layering). TCP carries SMTP (Simple Mail Transfer Protocol) and HTTP (Hypertext Transfer Protocol) amongst others. The equivalent connectionless protocol is UDP.
Transmission Control Protocol / Internet Protocol. Strictly speaking, TCP/IP just means TCP and IP together but is often used to designate the whole IPS (Internet protocol suite).
Structured Query Language. The de facto standard language for interrogating a database defined by ISO and ANSI. Likely to be replaced by XQuery in the long term.
General Packet Radio Service. A packet radio protocol extension to GSM to support packet data over the air interface, services supported include IP, SMS and X.25. Contrast CSD (circuit switched data). The major components of GPRS networks are GGSN, SGSN, PCU. User data is carried across GPRS networks by SNDCP and GTP protocols and between GPRS networks by GRX (GPRS Roaming eXchange). More about GPRS in the FBMC GPRS Briefing
Global System for Mobile Communications. A Second Generation world standard for digital cellular networks (formerly Groupe Speciale Mobile). GSM network components are -
• MS (mobile station, the GSM phone, consisting of ME and SIM),
• BTS (base station),
• BSC / BSS,
• MSC (mobile switching centre, the mobile telephone exchange),
• HLR (home location register, the real-time subscriber database),
GSM supports two thirds of world mobile phone subscribers (according to GSM Association figures) and has experienced a rapid growth in SMS messaging in recent years. GSM is now being enhanced by GPRS and EDGE. UMTS is intended to be the Third Generation replacement for GSM. Other Second Generation systems include IS-136 (TDMA), IS-95 (CDMA) and PDC. First Generation systems include AMPS, TACS and NMT.
GSM Modem
Informal name for a GSM mobile device with an external data interface which is used to carry non-voice traffic, such as SMS, cell broadcast, USSD, EMS, MMS, GPRS, CSD and HSCSD. Most GSM phones support some or all of these and most also have external data interfaces but the term GSM Modem is most often used for a device which is never used for voice and which has an external power source (mains, vehicle power) or is embedded in some other system (as in a PCMCIA card). It is not truly a modem, of course, since GSM is inherently digital and therefore no digital to analogue conversion is required.
