(Telecompaper) The Next Generation Mobile Networks (NGMN) Alliance announced the launch of a work-programme to develop the end-to-end requirements for 5G. Earlier this year, the NGMN Alliance published a white paper on 5G operator requirements. The work-programme will build on and further evolve the white paper guidelines in order to support the standardisation and subsequent availability of 5G for 2020 and beyond. The NGMN members, which include operators, vendors and research Institutes, have agreed on four areas of work: Business Principles (business models, operator capabilities, vertical industry services), requirements and architecture (technical requirements, architecture guidelines, SDO input), spectrum (spectrum position for WRC-15, 5G spectrum requirements and evaluation) and intellectual property (standards essential patent declaration and assessment, 5G patent pool). A team of NGNM members has been set up for each area in order to develop the 5G requirements and design principles, analyze potential 5G solutions and assess future use-cases and business models. The outcome of the work will be shared and discussed with all relevant industry-organisations, SDOs and research groups.
