3GPP Officially Approved the Proposal by 5G
March 7th, the seventy-fifth plenary session of the 3GPP adopted the 5G accelerated proposal, according to the acceleration of the new time node: non independent 5G new standards will be completed in December 2017, frozen in March 2018. The proposal was supported by most of the industry's heavyweights. This acceleration is conducive to promoting the part of the operator as soon as possible to achieve large-scale testing and deployment of 5G in 2019 to the new.
Prior to the establishment of the 5G standard, the time node of the standard formulation is widely discussed. First of all, the standard needs to meet the ITU standard 5G submission time (2020), taking into account the ITU meeting arrangements, 3GPP to complete the 5G standard in the middle of 2020. Followed by Japan and South Korea proposed to host the Olympic Games or commercial 5G, the Tokyo Olympic Games in 2020, and the changPing Winter Olympics in 2018. Based on this schedule, Industry determines the two stages of 5G Phase 1(Rel-15) and Phase 2 (Rel-16). Because the 5G core network and the empty side is evolved, the plan was first completed in core network and interface standard, Rel-15 transition, the use of 4G core network (EPC) to provide services for the 5G air interface (double connection later supported by Option 3).
Since then adjust again, part of the work of phase 2 was advanced to phase 1. Phase 1 is required to complete the 5G air interface standards, but also to complete the core network standards and can provide services for the new air interface, which have independent ability.
Thus, in June 2016 the revised timetable is, Phase 1 is divided into two stages: The first stage is the original Phase 1 4G core network 5G service interface, plan is completed in March 2018 or December 2017, the second stage is the 5G core network, and provide services for the 5G air interface, plan is completed in June 2018.
At that time, there are some disputes over the completion of the non independent agreement, agreed in March 2017 when the Rel-15 project to determine all the time node. Thus, there is an accelerated proposal for this PR and 3GPP plenary session, specific content is: determine four times: december 2017 to complete the NSA standard, frozen in March 2018, completed the SA standard in June 2018, frozen again in September ASN.1; at the same time, in order to avoid the consistency of the two versions of the same before and after the internal release, presented the first version of backward compatibility is to have, if necessary, can be in the first version of frozen and then revised.
Compared with the previously determined time plan, the only difference is the accelerated version added a non independent air interface standard completion time points (December 2017), and the independent empty completion time is still unchanged, June 2018.
Is the largest acceleration, ahead of schedule and freeze on non empty independent protocol, non empty independent product development time of 6 months. According to the usual cycle, independent support for non empty products will be listed before the end of 2019. If you do not accelerate, 5G phone will be postponed until 2020 listing.
