3GPP RAN Workshop on LAA

Beijing, August 29, 2015

3GPP work on Licensed-Assisted Access (LAA) continues to attract wide industry attention, especially with regard to the coexistence mechanisms being designed for LTE to operate in unlicensed spectrum. Because of this 3GPP RAN has decided to hold an open industry workshop on LAA. The workshop will take place in Beijing on August 29, 2015. 

The LAA project was started to study the necessary modifications of LTE to operate in unlicensed spectrum. The project has recently reached an important milestone with the completion of the feasibility study and the approval of the corresponding Technical Report 36.889. Based on the conclusion of the study 3GPP RAN has decided to move the project to normative phase with the specification of LAA downlink operation in Rel-13 (uplink operation will be specified in a later release of LTE). The detailed objectives of the Rel-13 specification work can be found in RP-151045.

Low cost m2m over LTE

July 23, 2015

3GPP has completed a study on optimizing LTE for machine-type communications (MTC), to provide devices that are cost competitive with existing 2G equipment.

With the publication of TR36.888 a "Study on the provision of low-cost MTC User Equipment based on LTE" 3GPP has set the minimum requirements that will:

LTE Broadcast Test Specifications demonstrate Device Conformity

July 9, 2015

By Olivier Genoud, TF160 Leader

3GPP has always recognized the importance of having standardized test specifications available to manufacturers and certification bodies, in order to ensure the highest level of interoperability of mobile devices.

In the first half of 2015 a new important milestone was reached by the test experts from 3GPP Task Force 160 (TF160). In collaboration with test platform vendors (providing wireless network simulators) and device manufacturers (providing real wireless handsets), TF160 have completed the verification of Release 11 TTCN-3 protocol test cases specified for the FDD part of the eMBMS Service Continuity (eMBMS-SC) Feature.

The Evolved Multimedia Broadcast/Multicast Service for LTE (eMBMS), or “LTE Broadcast”, enables the delivery of the same content simultaneously to a very high number of users through the efficient usage of radio resources. It is particularly suited to the delivery of live video events, public alerts and the distribution of software updates for mobile devices.

Security Paper and Workshop Presentations

July 1, 2015

The updated ETSI White paper on "Security for ICT" now includes important new information on the work being done for the "Cyber", "Cloud" and "IoT" security in ETSI groups. The paper also covers 3GPP with dedicated sections on GSM, UMTS & LTE and details of current security aspects of 3GPP work on:

  • Machine Type Communications (MTC),
  • Public Warning Systems,
  • Proximity Services (ProSe) and Group Communication over LTE
  • Mission Critical Push To Talk over LTE (MCPTT)
  • Spoofed Call Detection and Prevention,
  • Security Assurance Specification (SAS) for the MME network product class,
  • Subscriber privacy,
  • Single Sign On frameworks between 3GPP networks and user-centric Web services.

Although the paper does not cover 5G specifically, it does demonstrate effectively how future systems call for security capabilities beyond what has been previously available and provides a snap shot of what ETSI and 3GPP are doing to meet the challenge.
