{"name":"R5-196989","title":"NGMN Operators Joint Position on 5G Core Connectivity Options","source":"NGMN Alliance Board Members","contact":"Ingbert Sigovich","contact-id":28887,"tdoctype":"LS in","for":"Information","abstract":"1. About the NGMN Alliance\nThe NGMN Alliance is an industry organization of leading world-wide telecom operators, vendors and research institutes (see www.ngmn.org) and was founded by international network operators in 2006. Its objective is to ensure that the functionality and performance of next generation mobile network infrastructure, service platforms and devices will meet the requirements of operators and, ultimately, will satisfy end user demand and expectations. The NGMN Alliance will drive and guide the development of all future mobile broadband technology enhancements with a focus on 5G. The targets of these activities are supported by the strong and well-established partnership of worldwide leading operators, vendors, universities, and successful co-operations with other industry organisations.\n2. Intention of the LS and required actions\nNGMN is pleased to inform 3GPP TSG RAN WG5 about NGMN operators\u2019 joint position on 5G Core Connectivity Options, which highlights the importance of supporting all Core Connectivity options defined by 3GPP for connection of LTE & NR radio equipment to EPC (LTE Evolved Packet Core, used by 4G networks today) and the new 5G core network.\nNGMN operators expressing their strong opinion that all of the Core Connectivity options are essential to efficiently deliver services enabled by the 5G core network across operators\u2019 LTE & NR radio network deployments and ensure seamless service continuity between these areas. It is therefore imperative that the complete 5G industry supports all of the specified options.\n3GPP has defined four possible configurations (known as options 2, 4, 5 & 7) for connecting to the new 5G core via LTE and\/or NR radio access technologies. 3GPP has also defined one option for 5G radio networks to be supported using EPC, known as option 3.\nWhilst options 2 and 3 have been well supported by the industry to date particularly in the context of initial 5G launches, NGMN operators also require support of options 4, 5 and 7 as they look to introduce 5G services across their networks. \nFor option 4, by aggregating LTE carriers to NR, operators can maximize capacity and make efficient use of existing LTE assets. Option 5 can offer advanced 5G core network supported service capabilities to LTE coverage areas and thus provide service continuity between LTE and NR. As to option 7, in addition to the advantages of option 5, operators can make use of the benefit of dual-connectivity by aggregating NR carriers to LTE.\n3GPP have confirmed that all architecture options are delivered in Release 15 specifications with options 4 & 7 delivered in \u2018late drop\u2019.\nA 5G core network offers substantial service benefits through native support of capabilities such as Network Slicing, Mobile Edge Computing (MEC) and uRLLC, with a new end-to-end QoS model. The 5G core network is also based on a modular Service Based Architecture providing a cloud-optimised framework for flexible service creation, automation, scalability and resilience. \nWith demand for radio performance improvements and industry uptake of wide area advanced 5G core network supported service capabilities, the mobile communications industry requires multiple connectivity options to meet the operator requirements.\nThis NGMN liaison is intended as NGMN operators\u2019 joint input on 5G core connectivity options. We appreciate 3GPP taking this into consideration in the conformance test development planning.\nFeedback on the outcome of RAN5 test development planning for these options is welcome. Please contact us in case of any immediate question.","secretary_remarks":"","agenda_item_sort_order":26,"ainumber":"7.2.3","ainame":"\tOther open issues from joint sessions - original A.I. retained","tdoc_agenda_sort_order":698900,"status":"noted","reservation_date":"2019-09-03 11:43:07","uploaded":"2019-09-03 11:47:53","revisionof":"","revisedto":"","release":"","crspec":"","crspecversion":"","workitem":"","crnumber":"","crrevision":"","crcategory":"","tsg_crp":"","lsreplyto":"","lsto":"","Cc":"","lsoriginalls":"190826 Liaison_NGMN_to_3GPP_Architecture options v2","lsreply":"","link":"http:\/\/www.3gpp.org\/ftp\/TSG_RAN\/WG5_Test_ex-T1\/TSGR5_84_Ljubljana\/Docs\/R5-196989.zip","group":"R5","meeting":"R5-84","year":2019,"uicc_affected":null,"me_affected":null,"ran_affected":null,"cn_affected":null,"clauses_affected":null,"crsinpack":null,"crsinpacknumber":0}]
