GMPRS (GEO-Mobile Packet Radio Service): Adding support for packet data. The equivalent of GPRS in the GSM world. Still connected to a 'Gb' style core network. GMR-1 3G: Adds support for some new channel types, but the most important changes are in the core network, adding interoperability with UMTS core network components.
GPRS Tunnelling Protocol (GTP) is a group of IP-based communications protocols used to carry general packet radio service (GPRS) within GSM, UMTS, LTE and 5G NR radio networks. In 3GPP architectures, GTP and Proxy Mobile IPv6 based interfaces are specified on various interface points.
In the UMTS system the data connection between a GPRS Core Network and a mobile station is identified using an NSAPI, that identifies as well a radio access bearer. In the previous releases of GPRS (pre-Release’00), a connection is identified by NSAPI and a Logical Link Control (LLC) protocol SAPI. However, in UMTS, and thus in GPRS Release ...
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).
GPRS opened in 2000 [21] as a packet-switched data service embedded in the channel-switched cellular radio network GSM. GPRS extends the reach of the fixed Internet by connecting mobile terminals worldwide. The CELLPAC [22] protocol developed 1991–1993 was the trigger point for starting in 1993 the specification of standard GPRS by ETSI SMG.
There are also several GSM/UMTS PS interfaces in the Serving GPRS Support Node (SGSN) transported over SS7: Gr -> HLR for attaching to the PS network and location update; Gd -> SMS-C for SMS over PS; Gs -> MSC for combined CS+PS signaling over PS; Ge -> Charging for Customised Applications for Mobile networks Enhanced Logic (CAMEL) prepaid charging
Globe Telecom, Inc., commonly shortened as Globe, is a major provider of telecommunications services in the Philippines.The company operates the largest mobile network in the Philippines and one of the largest fixed-line and broadband networks.
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).
