GPRS Tunnelling Protocol is the defining IP-based protocol of the GPRS core network. Primarily it is the protocol which allows end users of a GSM or WCDMA network to move from place to place while continuing to connect to the Internet as if from one location at the Gateway GPRS support node (GGSN).
The Mobile Application Part is the application-layer protocol used to access the Home Location Register, Visitor Location Register, Mobile Switching Center, Equipment Identity Register, Authentication Centre, Short message service center and Serving GPRS Support Node (SGSN).
As the GPRS standard is an extension of GSM capabilities, the service operates on the 2G and 3G cellular communication GSM frequencies. [10] [12] GPRS devices can typically use (one or more) of the frequencies within one of the frequency bands the radio supports (850, 900, 1800, 1900 MHz). Depending on the device, location and intended use ...
When the subscriber sends a Short Message, the handset sends the text message over the air interface to the Mobile Switching Center (MSC)/Serving GPRS Support Node (SGSN). Along with the actual text of the Short Message, the destination address of the SM and the address of the Short Message service center (SMSC) are included, the latter taken ...
An 'Access Point Name' (APN) is the name of a gateway [2] between a mobile network (GSM, GPRS, 3G, 4G and 5G) and another computer network, frequently the public Internet. [3] Some Important APN Terms: Below are some terms of the APN settings, explaining what each setting stands for: APN: The APN address of your (mobile network operator) MNOs.
Typical 2G standards include GSM and IS-95 with extensions via GPRS, EDGE and 1xRTT, providing Internet access to users of originally voice centric 2G networks. Both EDGE and 1xRTT are 3G standards, as defined by the ITU , but are usually marketed as 2.9G due to their comparatively low speeds and high delays when compared to true 3G technologies.
The Um physical layer is defined in the GSM 05.xx series of specifications, with the introduction and overview in GSM 05.01. For most channels, Um L1 transmits and receives 184-bit control frames or 260-bit vocoder frames over the radio interface in 148-bit bursts with one burst per timeslot.
BSSGP is a protocol used in the GPRS mobile packet data system. It denotes Base Station System GPRS Protocol . It transfers information between two GPRS entities SGSN and BSS over a BSSGP Virtual Connection (BVC).
