End-to-End Network Slicing in Radio Access Network, Transport Network and Core Network Domains

Abstract

Network slicing (NS) has been well discussed in the transport network (TN) and core network (CN) domains. This paper extends it to the radio access network (RAN) domain, and the NS in RAN, TN and CN domains is defined as end-to-end (E2E) NS system. The advantages of using NS in the RAN domain with two-level resource allocation scheme are studied and shown by numerical simulations. Then the E2E NS system architecture and components are proposed and demonstrated with hardware and software. The demonstration shows the capability with very fine spectral granularity, and the slice creation, delete and adjustment schemes in sub-minute time, which could be used in the operator's network. INDEX TERMS End-to-end network slicing, radio access network, spectrum allocation, demonstration.

“…Similar to the uplink case, the KKT condition (18) here too still involves the Lagrange multipliers, whereas conditions (19), (20), and (21) do not. Therefore, (19), (20) and ( 21) are necessary and sufficient conditions for the solution of our problem.…”

Therefore, (19), (20) and ( 21) are necessary and sufficient conditions for the solution of our problem. Following the guidelines in [23], we set the derivatives equal to zero, combine (19) and (21) to get closed-form solutions to the problem with the necessary conditions.…”

“…However, they considered only eMBB and uRLLC heterogeneous services and used max-matching diversity (MMD) algorithm to improve the achievable rate of both services. Authors in [19] defined network slicing in RAN, TN, and CN domains as an end-to-end network slicing system, and proposed the system architecture and components to demonstrate its capability with hardware and software. A novel RAN slicing architecture with slices providing services by choosing an appropriate functional split option and its placement is provided in [20].…”

Análisis basado en teoría de juegos de modelos de negocio de operadores móviles virtuales en redes 4G y 5G

“…En el mismo contexto de la asignación dinámica de recursos, en[77,85] los autores analizan un modelo de asignación de recursos dinámico, basado en NS que permite a los inquilinos personalizar la asignación de recursos dentro de su segmento de red, en el análisis se considera el comportamiento estratégico de un inquilino que ajusta sus preferencias, en función de la congestión percibida en los recursos, a fin de maximizar su propia utilidad. Finalmente, se presentan varios estudios que plantean escenarios de compartición de los recursos de las estaciones base del InP con un MVNO, en un esquema de dos niveles[52], que podría utilizarse para asignar recursos al MVNO y sus usuarios móviles[121][122][123]. En la primera etapa, se asignan recursos al MVNO y se maximizan los ingresos del InP sobre la base de la información recibida del MVNO, como los requisitos de ancho de banda, la utilización de recursos y el precio de oferta y en la segunda etapa, se asignan recursos a los usuarios de cada MVNO.En relación con al análisis descrito en párrafos anteriores, la solución en los escenarios mencionados se aborda el análisis de la viabilidad económica de la compartición de infraestructura, considerando conceptos de la teoría de juegos, microeconomía,teoría de colas y optimización.En este sentido, a continuación analizamos varias obras que nos permiten complementar el análisis de los modelos de negocio dentro del marco metodológico de esta tesis.…”
