摘要/Abstract

摘要：

未来无线通信网络将是一个多种无线接入方式共存的异构网络，如何实现异构网络在频谱、软硬件资源等方面的融合是一个亟需解决的问题。现有方案受限于不同网络独立部署的架构，无法真正实现异构网络资源的融合。针对该问题，提出了一种新型的基于集中式接入网架构的异构网络融合平台，可以在集中式资源池基础上进行异构网络间处理资源及无线资源的共享与统一管理。基于该平台，进一步阐述了异构网络资源管理的关键技术，包括基站资源虚拟化、处理资源按需分配、动态频谱共享、网络覆盖优化及性能分析验证方法等，为未来异构网络融合研究提供了一种可行的方案。

Abstract:

The future broadband wireless communication network will be a heterogeneous network with multiple access technologies seamlessly integrated. In such heterogeneous network, the key issues are how to share resources such as frequency, software, hardware and so on among different types of networks to reduce cost as well as to provide better services to users. Therefore, a heterogeneous network resource convergence platform was proposed based on the centralized radio access network architecture. This platform provides a feasible solution to support resource cooperation among different networks. Moreover, the key technologies were illustrated in detail, such as resource virtualization, processing resource allocation, dynamic frequency share, network coverage optimization, system performance analysis, etc.

Key words: heterogeneous network, centralized radio access network architecture, resource convergence platform, resource virtualization, resource management
