Problems solved by technology

However, the COMP scheme often requires additional signaling overhead and computing power
For the current LTE network architecture, the cost of deploying some COMP solutions will be high
Also, the closed design of the Enhanced Packet Core (EPC) architecture may only allow for vendor-specific CoMP schemes

Embodiment Construction

[0017] The present disclosure will be described with respect to exemplary embodiments in a specific context, namely, a communication system for on-demand radio coordination in software-defined networks. The disclosed content can be applied to standard compliant communication systems using advanced multiple access technology, such as 3rd Generation Partnership Project (3GPP), IEEE802.11 and other technical standards compliant communication systems, as well as non-standard compliant communication systems. Certain wireless technologies, such as LTE, may be mentioned in the description. It should be understood, however, that the described embodiments are applicable to other technologies such as GSM (Global System for Mobile Communications), UMTS (Universal Mobile Telecommunications System) and future wireless communication technologies such as cellular wireless networks without cell IDs.

[0018] In an LTE network, the operating parameters of the radio nodes can be automatically c...

Abstract

A network includes network components configured to perform a method for on-demand radio coordination. The method includes determining a congested radio node in a plurality of radio nodes in the network in response to congestion information received from a network device. The method includes generating a cluster of radio nodes associated with the congested radio node. The method also includes optimizing radio resources of the radio nodes in the cluster to produce cluster optimization results configured to alleviate congestion of the congested radio node. The method further includes transmitting the cluster optimization results to the radio nodes in the cluster to alleviate the congestion.

Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS [0002] This application requires U.S. Provisional Application No. 61 / 920,650, filed December 24, 2013, entitled "On-Demand Radio Coordination in Software-Defined Networks," and Application No. 14 / , filed December 23, 2014 581,867, Priority to US non-provisional application entitled "On-Demand Radio Coordination in Software Defined Networks," the contents of which are incorporated herein by reference. technical field [0003] The present disclosure provides mechanisms for coordinating radio nodes in a software-defined network. Background technique [0004] In cellular networks, co-channel interference (CCI) caused by frequency reuse is one of the factors limiting system capacity. Many measures to mitigate CCI have been studied and applied in cellular systems. For example, soft frequency reuse in the power and frequency domains, enhanced inter-cell interference coordination (eICIC) in the time domain, and coordinated multipoin...
