Abstract

A method is provided for enabling a base station to infer a compact topology graph among a set of mobile nodes in its cell, the mobile nodes having a secondary radio to enable inter-nodal communication. This methodology ensures that nodal membership information is gathered within approximately 100 ms, and additional topology information is gathered from all the mobile nodes within approximately 300 ms over Wi-Fi radios. In dense networks, this time can be reduced to within 100 ms.

Description

technical field [0001] The present invention relates generally to node mapping for wireless communication systems. Background technique [0002] Contemporary wireless communication systems are characterized by the use of a variety of radio access technologies, some of which stem from the evolution of successive generations of cellular communication services, while others represent wireless Communication service. Examples of the former include Universal Mobile Telecommunications System (UMTS) and Long Term Evolution (LTE), while 802.11 services such as Wi-Fi are examples of the latter. A multi-mode user terminal (hereinafter generally referred to as a mobile node) having RF capabilities compatible with two or more radio access technologies can switch to the most suitable available technology at the relevant time. This brings benefits to both users and network operators running multiple technologies in their networks: users can access a network running a given technology at ...
