Abstract

An application requirement of an application running on a wireless device in communication with a first access node, a traffic class indicator associated with the wireless device, and a wireless communication link load between the wireless device and the first access node are determined. A probability of performing a first handover of the wireless device to a second access node and a second handover of the wireless device from the second access node to the first access node within a predetermined period of time is also determined. Based on the application requirement, the traffic class indicator, the wireless communication link load, and the determined probability, a context maintenance time is calculated, and a timer is started using the context maintenance time when the first handover is performed, and communication session information related to the communication between the wireless device and the first access node is maintained until the timer expires.
