Abstract: A device receives, from multiple network elements, status information for a user equipment (UE) connection associated with a wireless core network and updates, based on the status information received from the network elements, a database record for the UE connection. The device receives, from an application server, a request for information associated with the UE connection and constructs, based on the request and from the database record, a resource message that includes real-time information about the UE connection. The device sends the resource message to the application server. The device also provides a disconnect message to the application server and/or the network elements when the status information received from the network elements indicates that the UE has been disconnected from the wireless core network.

Abstract: A network socket application programming interface (API) running on a communication device is operative to provide, to applications running on the device, information about the performance of communication links used by sockets for communicating across a network. The socket API receives packets associated with sockets, and retrieves from the packets performance information for corresponding communication links. In response to receiving a request from an application for performance information associated with a particular socket, the API identifies performance information for the particular socket and returns the retrieved information to the application. A performance monitoring network device provides the performance information.
