Title: Innovations of Nicholas Dougall Johnson
Introduction

Latest Patents
One of his latest patents is titled "Network elements, wireless communication system and methods therefor." This invention describes a method and apparatus for redirecting a wireless communication unit from an LTE cell to a neighboring 3G or 2G cell. The purpose of this redirection is to perform procedures that are available in the 2G or 3G cell but not in the LTE cell. The invention includes the provision of an additional LTE access point within the coverage area of an LTE macrocell. This access point captures a wireless communication unit that is camped onto the LTE macrocell and redirects it to a 3G/2G cell, regardless of whether a better service may be provided in the 2G/3G cell. This innovation has applications in presence detection, where the collection of wireless communication units' and subscribers' IDs is possible in 3G and 2G cells but not in LTE cells.
Another notable patent is "Wireless communication unit, access point and method for providing a presence service in a wireless communication system." This patent outlines a presence service that can be provided by an access point serving a small cell. The method involves rejecting a registration request from user equipment after acquiring its IMSI and sending the IMSI to a presence database. The user equipment determines if the cell is a presence cell by comparing the cell's location area code (LAC) with stored LACs. If a match is found, the user equipment retries registration after a pre-set time period of 5-10 minutes. This approach allows for the notification of subscribers who linger in a particular area or return to that area at regular intervals.
