What are 3GPP specifications?

The term “3GPP specification” covers all GSM (including GPRS and EDGE), W-CDMA (including HSPA), LTE (including LTE-Advanced and LTE-Advanced Pro) and 5G specifications. Revised versions of many of these specifications are produced up to four times a year following the quarterly TSG plenary meetings.

What is Diameter protocol in telecom?

The Diameter Protocol provides authentication, authorization, and accounting (AAA) messaging services for network access and data mobility applications in 3G, IP Multimedia Systems (IMS), and LTE/4G networks.

What is Interface diameter?

Diameter interfaces provide connections among Diameter nodes to enable essential service provider network functions such as authentication, online and offline billing, and policy and charging.

How do I read 3GPP specs?

All 3GPP specifications have a specification number consisting of 4 or 5 digits. (e.g. 09.02 or 29.002). The first two digits define the series, followed by 2 further digits for the 01 to 13 series or 3 further digits for the 21 to 55 series.

Is 5G a 3GPP standard?

3rd Generation Partnership Project (3GPP) members meet regularly to collaborate and create cellular communications standards. Currently, 3GPP is defining standards for 5G. Different groups, each with a specific focus area, make up 3GPP.

What is difference between 3GPP and non 3GPP?

Non-3GPP means that these accesses were not specified in the 3GPP. These technologies includes e.g. WiMAX, cdma2000®, WLAN or fixed networks. Non-3GPP accesses can be split into two categories: the “trusted” ones and the “untrusted”: Trusted non-3GPP accesses can interact directly with the EPC.

Is Diameter used in 5G?

So, where does Diameter fit in with 5G? The cloud-native SBA that 5G offers is unprecedented and promises a host of benefits and advantages. But, as it uses HTTP/2 protocol for communication between network functions (NFs), 5G SBA will not need Diameter.

Is Diameter a TCP or UDP?

Like RADIUS, Diameter provides AAA functionality, but uses TCP and SCTP instead of UDP, therefore delegating detection and handling of communication problems to those protocols.

Why is Diameter used instead of Radius in 3gpp systems?

It used either Transmission Control Protocol (TCP) or Stream Control Transmission Protocol (SCTP) as its transport layer; unlike RADIUS, Diameter supports Agents (Relay, Proxy, Redirect, and Translation); it supports client-initiated messages; it supports capability negotiation to name a few.

What is the difference between SIP and Diameter?

Diameter and SIP (Session Initiation Protocol) are the core signaling protocols used in IMS networks. SIP is used to establish and control real-time IP communications sessions. Diameter is used to authenticate, authorize and provide accurate billing information for those sessions.

What is the main specification of 5G?

5G can be significantly faster than 4G, delivering up to 20 Gigabits-per-second (Gbps) peak data rates and 100+ Megabits-per-second (Mbps) average data rates. 5G has more capacity than 4G. 5G is designed to support a 100x increase in traffic capacity and network efficiency. 5G has lower latency than 4G.

What is the purpose of 3GPP?

The 3rd Generation Partnership Project (3GPP) is a collaborative project between a group of telecommunications associations with the initial goal of developing globally applicable specifications for third-generation (3G) mobile systems.

What is SS7 and Diameter?

While SS7 was the foundation for signaling in 2G/3G circuit switch networks, Diameter has been introduced for 4G LTE and VoLTE packet networks and IP Multimedia Subsystem (IMS) based systems, and is key to enabling new revenue-generating IP services.

What port does Diameter use?


TCP or SCTP: Typically DIAMETER uses TCP or SCTP as its transport protocol. Its well-known port is 3868. Its well-known SCTP Payload Protocol Identifier is 46 (47 when encrypted with DTLS).

Why do we use Diameter?

It is a crucial measurement of circles. In fact, it is one of the defining measurements of circles. The diameter measures how big the circle is from rim to rim passing through the center.

What is the bandwidth of 5G?

5G speeds will range from around 50 Mbps to 1,000 Mbps (1 Gbps) depending on the RF channel and BS load. The fastest 5G speeds would be in the mmWave bands and can reach 4 Gbit/s with carrier aggregation and MIMO (assuming a perfect channel and no other BS load).

Who uses 3GPP?

3GPP unites telecommunications standards organizations around the world, such as Japan’s Association of Radio Industries and Businesses (ARIB) and Telecommunication Technology Committee (TTC); China Communications Standards Association (CCSA); South Korea’s Telecommunications Technology Association (TTA); European …

Does 5G use SS7?

SS7 was first adopted as an international standard in 1988, and the latest revision of the standard was in 1993. It is still the current standard for telephone calls and is in use for both landline and mobile phone service all the way up to and including 5G.

Does LTE use SS7?

Because of this, starting with the rollout of 4G (LTE) networks, SS7 was replaced with the Diameter protocol, an improved inter and intra-network signaling protocol that’s also slated to be used with the upcoming 5G standard.

Why is Diameter used instead of RADIUS in 3gpp systems?

Is Diameter an application layer protocol?

The Diameter protocol is an application layer protocol that provides authorization, authentication, and accounting (AAA) services to computer networks and network applications.

How many types of diameters are there?

In Geometry, we have studied two different types of shapes. They are 2D shapes and 3D shapes.

How is diameter calculated?

It is twice the length of the radius of a circle, i.e., Diameter = 2 × Radius.

Is 5G TDD or FDD?

In general, FDD is considered better for coverage and TDD better for capacity. Mobile operators are looking to carrier aggregation (CA), which allows them to use multiple sub-6 GHz spectrum channels simultaneously, as a method of increasing the bandwidth and speeds of their 5G networks.

Can 5G penetrate walls?

It has a long reach, with the ability to cover very large areas and penetrate walls. With it, we can bring 5G virtually everywhere across the country, even to far-flung places like small towns and rural areas.
