2. 3GP and 3G2 - Wikipedia

   en.wikipedia.org/wiki/3GP_and_3G2

   3GP is defined in the ETSI 3GPP technical specification. [1] 3GP is a required file format for video and associated speech/audio media types and timed text in ETSI 3GPP technical specifications for IP Multimedia Subsystem (IMS), Multimedia Messaging Service (MMS), Multimedia Broadcast/Multicast Service (MBMS) and Transparent end-to-end Packet-switched Streaming Service ().

3. Dual Transfer Mode - Wikipedia

   en.wikipedia.org/wiki/Dual_Transfer_Mode

   Dual Transfer Mode (DTM) is a protocol based on the GSM standard that makes simultaneous transfer of Circuit switched (CS) voice and Packet switched (PS) data over the same radio channel simpler. Without DTM, the mobile device must be capable of reception and transmission simultaneously (full-duplex) requiring complex and expensive circuitry in ...

4. Customized Applications for Mobile networks Enhanced Logic

   en.wikipedia.org/wiki/Customized_Applications...

   Phases 1 and 2 were defined before 3G networks existed, and as such support adding IN services to a GSM network, although they are equally applicable to 2.5G and 3G networks. Phase 3 was defined for 3GPP Releases 99 and 4, and hence is a GSM and UMTS common specification, while Phase 4 was defined as part of 3GPP Release 5.

5. Multimedia Broadcast Multicast Service - Wikipedia

   en.wikipedia.org/wiki/Multimedia_Broadcast...

   The Download Delivery Method is intended for “download and play” services. A File Repair service may be offered to compensate for unreliable delivery. MBMS has been standardized in various groups of 3GPP (Third Generation Partnership Project), and the first phase standards are found in UMTS release 6. As Release 6 was functionally frozen by ...

6. GSM 03.40 - Wikipedia

   en.wikipedia.org/wiki/GSM_03.40

   GSM 03.40 or 3GPP TS 23.040 is a mobile telephony standard describing the format of the Transfer Protocol Data Units (TPDU) part of the Short Message Transfer Protocol (SM-TP) used in the GSM networks to carry Short Messages. [1] This format is used throughout the whole transfer of the message in the GSM mobile network.

7. Media gateway - Wikipedia

   en.wikipedia.org/wiki/Media_gateway

   Media Gateways are used for transcoding media between PSTN and IP networks. A media gateway is a translation device or service that converts media streams between disparate telecommunications technologies such as POTS, SS7, Next Generation Networks (2G, 2.5G and 3G radio access networks) or private branch exchange (PBX) systems.

8. Short Message Service technical realisation (GSM) - Wikipedia

   en.wikipedia.org/wiki/Short_Message_Service...

   The Short Message protocol itself is defined by 3GPP TS 23.040 for the Short Message Service - Point to Point (SMS-PP), [2] and 3GPP TS 23.041 for the Cell Broadcast Service (CBS). [3] Four MAP procedures are defined for the control of the Short Message Service: [1] Mobile Originated (MO) short message service transfer;

9. High Speed Packet Access - Wikipedia

   en.wikipedia.org/wiki/High_Speed_Packet_Access

   A further-improved 3GPP standard called Evolved High Speed Packet Access (also known as HSPA+) was released late in 2008, with subsequent worldwide adoption beginning in 2010. The newer standard allows bit rates to reach as high as 337 Mbit/s in the downlink and 34 Mbit/s in the uplink; however, these speeds are rarely achieved in practice.
