Control and User Plane Separation of EPC nodes (CUPS)

July 03, 2017

By Peter Schmitt (Huawei), Bruno Landais (Nokia), Frank Yong Yang (Ericsson)

At the recent CT#76 meeting (June 2017), 3GPP has completed the Release 14 specification of CUPS – set to be a key core network feature for many operators.

CUPS stands for Control and User Plane Separation of EPC nodes and provides the architecture enhancements for the separation of functionality in the Evolved Packet Core’s SGW, PGW and TDF. This enables flexible network deployment and operation, by distributed or centralized deployment and the independent scaling between control plane and user plane functions - while not affecting the functionality of the existing nodes subject to this split.

Mission Critical Services in 3GPP

June 20, 2017

By Yannick Lair and Georg Mayer

A platform for mission critical (MC) communications and MC Services has been a key priority of 3GPP in recent years and is expected to evolve into the future by taking more requirements, from different sectors of the global critical communications industry, on board.

This article provides an overview of what was achieved so far in the MC domain within 3GPP and also gives an outlook of what can be expected in the near future. We plan to create a more detailed paper on MC Services, which will summarize the use cases and functional aspects of Rel-13, Rel-14 and upcoming Rel-15, later this year.

Driven by the 3GPP release schedule, the mission critical related functionalities have been phased across them, each release encompassing a complete set of standards for equipment vendors and operators to phase their implementations and deployments, based on market demands.

TCCA CEO retires amid plaudits for 3GPP role

July 21, 2017

Phil Kidner has announced his retirement after eleven years at the helm of the TETRA and Critical Communications Association. The TCCA is a Market Representation Partner in 3GPP.

TETRA became operational in the mid-90s being built on the ETSI standards and the TETRA Association’s expertise to bring it to market.

During Phil Kidner’s leadership the Association has been a major driver for the success of TETRA amongst Governments, Operators, Vendors and – vitally – the Users from the public safety and transport sectors.


LTE MCPTT testing

June 27, 2017
 
3GPP Market Representation Partner TCCA has worked closely with ETSI to produce their first Mission Critical Push to Talk (MCPTT) test event, held last week in Sophia Antipolis, focusing on test sessions for mission-critical LTE equipment.
 
140 participants from 19 companies carried out over 1000 tests based on 3GPP, ETSI and IETF standards – with 47 of the test cases specifically developed for Release 13 MCPTT.
