Altitude-Based Wireless Device Connection Handling

The patent applies preliminary action by having wireless devices obtain and report altitude information before connection handover decisions are made. The device retrieves altitude data from a database using base station identifiers, and provides this information to the network in advance, enabling more informed connection handling without increasing the complexity of the core signaling process

The patent introduces an intermediary mechanism by using a database that stores altitude information of base stations. This database acts as a mediator between the wireless device and the network, allowing altitude data to be obtained without direct complex interactions between devices and network nodes, thus improving efficiency while maintaining signaling simplicity

The patent applies partial action by selectively obtaining altitude information only when needed for connection handling decisions. The wireless device obtains altitude data for specific base stations that are candidates for connection or handover, rather than continuously monitoring all base stations, thus improving handover quality while minimizing additional signaling load

The patent implements self-service by having the wireless device autonomously obtain its own altitude information and that of target base stations using identifiers received from the network. The device independently queries the altitude database and processes this information locally, reducing the need for extensive network signaling and allowing the device to serve its own connection management needs
