3GPP – About 3GPP

3GPP – About 3GPP.

The 3rd Generation Partnership Project (3GPP) unites [Six] telecommunications standards bodies, known as “Organizational Partners” and provides their members with a stable environment to produce the highly successful Reports and Specifications that define 3GPP technologies.

These technologies are constantly evolving through – what have become known as – Generations of commercial cellular / mobile systems. 3GPP was originally the standards partnership evolving GSM systems towards the 3rd Generation. However, since the completion of the first LTE and the Evolved Packet Core specifications, 3GPP has become the focal point for mobile systems beyond 3G.

OsmocomBB

OsmocomBB.

OsmocomBB is an Free Software / Open Source GSM Baseband software implementation.

It intends to completely replace the need for a proprietary GSM baseband software, such as

  • drivers for the GSM analog and digital baseband (integrated and external) peripherals
  • the GSM phone-side protocol stack, from layer 1 up to layer 3

In short: By using OsmocomBB on a compatible phone, you are able to make and receive phone calls, send and receive SMS, etc. based on Free Software only.

Online Certificate Status Protocol

Online Certificate Status Protocol – Wikipedia, the free encyclopedia.

The Online Certificate Status Protocol (OCSP) is an Internet protocol used for obtaining the revocation status of an X.509 digital certificate. It is described in RFC 2560 and is on the Internet standards track. It was created as an alternative to certificate revocation lists (CRL), specifically addressing certain problems associated with using CRLs in a public key infrastructure (PKI). Messages communicated via OCSP are encoded in ASN.1 and are usually communicated over HTTP. The “request/response” nature of these messages leads to OCSP servers being termed OCSP responders.

Service Location Protocol

Service Location Protocol – Wikipedia, the free encyclopedia.

The Service Location Protocol (SLP, srvloc) is a service discovery protocol that allows computers and other devices to find services in a local area network without prior configuration. SLP has been designed to scale from small, unmanaged networks to large enterprise networks. It has been defined in RFC 2608 and RFC 3224 as Standards Track document.

Making a WiFi Hotspot / Access Point using Linux & wifi lan card/USB adapter

If you have a wifi LAN card / USB adapter, then you can use it as an access point so that other machines can connect to the internet via your machine using Wifi. The process is fairly simple, but requires you to have a compatible set of drivers which allow a wifi lan card to come into “Master” mode.

MQTT: MQ Telemetry Transport

MQTT stands for MQ Telemetry Transport. It is a publish/subscribe, extremely simple and lightweight messaging protocol, designed for constrained devices and low-bandwidth, high-latency or unreliable networks. The design principles are to minimise network bandwidth and device resource requirements whilst also attempting to ensure reliability and some degree of assurance of delivery. These principles also turn out to make the protocol ideal of the emerging “machine-to-machine” (M2M) or “Internet of Things” world of connected devices, and for mobile applications where bandwidth and battery power are at a premium.

via FAQ – Frequently Asked Questions | MQTT: MQ Telemetry Transport.

I see RIM phones using this.

Are there standard ports for MQTT to use?

Yes. TCP/IP port 1883 is reserved with IANA for use with MQTT. TCP/IP port 8883 is also registered, for using MQTT over SSL.
