IEEE P1900.4

Working Group on Architectural Building Blocks Enabling Network-Device Distributed Decision Making for Optimized Radio Resource Usage in Heterogeneous Wireless Access Networks  

Scope and objectives

IEEE Standard 1900.4 “Architectural building blocks enabling network-device distributed decision making for optimized radio resource usage in heterogeneous wireless access networks” was published on February 27th 2009. The standard can be obtained at: standards.ieee.org/findstds/standard/1900.4-2009.html .

IEEE Standard 1900.4a-2011 “Architectural Building Blocks Enabling Network-Device Distributed Decision Making for Optimized Radio Resource Usage in Heterogeneous Wireless Access Networks Amendment 1: Architecture and Interfaces for Dynamic Spectrum Access Networks in White Space Frequency Bands” was published on September 16th 2011. The standard can be obtained here:  standards.ieee.org/findstds/standard/1900.4a-2011.html.

During the QoSMOS lifetime, the Working Group worked on the project:

P1900.4.1: Standard for Interfaces and Protocols Enabling Distributed Decision Making for Optimized Radio Resource Usage in Heterogeneous Wireless Networks. This project aimed at defining the protocols and the Service Access Points (SAPs) associated with the interfaces standardized in IEEE 1900.4-2009. The WG finalised the draft standard P1900.4.1, which was approved by IEEE SASB to be published as IEEE Standard 1900.4.1-2013 (on 24th June 2013).

 

Technical Relevance for QoSMOS

The architecture defined in IEEE 1900.4a-2011 has a scope similar to the QoSMOS architecture since both address the coexistence of secondary systems and spectrum management in white space frequency bands (including the aspects related to the femtocell and “cellular extension” cases).

Due to the Chair position of a QoSMOS partner there were numerous submissions to this WG.

Beyond the necessary additions and clean-up to reach an implementation-ready level, the next step would actually be to define interfaces and protocols to support the operation in WS as defined in IEEE 1900.4a-2011.

Some of the protocols being defined in P1900.4.1 can be of interest to QoSMOS since they could be used in the system operating in white space frequency bands (developed in IEEE 1900.4a-2011).  

Status and outlook for QoSMOS

After finalising 1900.4.1, the 1900.4 WG has opened call for new project proposals. One candidate may be defining interfaces and protocols for the IEEE 1900.4a systems operating in white space frequency bands. As parts of the QoSMOS results could match in this, some of the QoSMOS partners may continue working in the WG.
