    Indosat acquired Satelindo and SLI through share majority. They also established PT Indosat Multimedia Mobile (IM3) to provide and operate a nationwide GPRS network, a first for the country. In 2003, Indosat merged with its 3 subsidiaries—Satelindo, IM3, and Bimagraha—and established itself as a mobile network operator.

    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).

  7. General Packet Radio Service - Wikipedia

    en.wikipedia.org/wiki/General_Packet_Radio_Service

    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 ...

    In GPRS Coding Schemes CS-1 through CS-3, the convolutional code is of rate 1/2, i.e. each input bit is converted into two coded bits. [5] In Coding Schemes CS-2 and CS-3, the output of the convolutional code is punctured to achieve the desired code rate. [5] In GPRS Coding Scheme CS-4, no convolutional coding is applied. [5]

    en.wikipedia.org/wiki/GPRS_Tunnelling_Protocol

    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.
