Patent number: 12513224Abstract: A push gateway brokers messages between backend services and client devices connected to the gateway. The gateway includes a plurality of messaging frontend servers, a messaging database, and a plurality of topic servers. The messaging frontend servers manage the socket connections connecting the client devices to the push gateway. The messaging database is a key-value database that subscribes messaging frontend servers to topics. The topic servers receive publish requests from the backend servers to identify subscribed messaging frontend servers in the messaging database to push messages out to. The frontend messaging servers subsequently push out the message to the client devices subscribed to the topic. The gateway can aggregate player counts from a plurality of geographical regions based on the socket connections hosted by the messaging frontend servers. With the player counts, the gateway can generate a player density map, e.g., for socket load balancing, or for a gameplay feature.Type: GrantFiled: March 22, 2024Date of Patent: December 30, 2025Assignee: Niantic, Inc.Inventors: Mingliang Wei, Maoyang Li, Michael Chang, Laura Tang
