Patent granted for location-based publications in cellular networks
A recently granted patent (Publication Number: US11956325B2) discloses a client device designed for use in a cellular network that offers location-based publications through a publish/subscribe protocol. The device includes a processor and memory storing program code instructions that enable it to determine its geographical location, identify a subscription geohash corresponding to its location, and send subscription requests to a server. Additionally, the device can determine neighboring geographical areas based on motion direction, adjust subscription levels according to speed, and manage subscriptions efficiently by unsubscribing or sending additional requests as needed.
Furthermore, the patent details a method for implementing location-based publications in a cellular network, involving steps such as determining the client device's location, selecting a subscription geohash, sending subscription requests, and identifying matching subscriptions for publication messages. The method also includes determining motion direction, selecting additional subscription geohashes for neighboring areas, and ensuring that publication geohashes correspond to subscription geohashes at each specified level. This innovative approach aims to enhance the efficiency and accuracy of location-based services in cellular networks, providing users with relevant and timely information based on their geographical context and movement patterns.
