Abstract
A method includes, in a wireless data network, monitoring communication conditions at an intermediate location between a wireless communication terminal and a network element that provides voice-call services over the network to the wireless communication terminal. Upon detecting that the communication conditions are expected to cause the wireless communication terminal to send a notification to the network element, an early notification is sent to the network element on behalf of the terminal. Another method includes detecting a notification in which a terminal notifies a network element of degraded reception performance. A modification, which the network element is expected to perform in a transmission characteristic to the terminal in response to the notification, is predicted. In-flight communication traffic, which is en-route to the terminal and whose transmission characteristic is not yet modified in response to the notification, is intercepted. The predicted modification is applied to the in-flight communication traffic.
