Claim Text:
1. A method of maintaining communication session information, comprising: determining, at an inspection node, an application requirement of an application running on a wireless device, a traffic class indicator associated with the wireless device, and a wireless communication link load; determining a probability for performing repeated handovers of the wireless device between a first access node using a first radio access technology and a second radio access technology based on a monitored number of re-connection requests made by the wireless device within a predetermined period of time; determining a backhaul load of the first access node; calculating a context maintenance time for the wireless device, wherein the context maintenance time is calculated based on the determined application requirement, traffic class indicator, wireless communication link load, backhaul load, and probability for performing repeated handovers; starting a timer using the calculated context maintenance time when a first handover of the wireless device is performed; and maintaining, at a network node, information related to a communication session between the wireless device and at least the first access node until the timer expires.
