A method and apparatus for analytics-driven wireless device session context handover in an operator cloud are provided. According to one aspect, some embodiments include a method for a network node to determine whether to perform a wireless device session context handover. The method includes determining, at the network node, a first cost of not handing over a wireless device session context based at least in part on a calculated estimate of time the wireless device will stay associated with a current base station and a calculated estimate of a cost per unit time of not performing the handover. The method also includes determining, at the network node, a second cost of handing over the wireless device session context based at least in part on at least one of context-related data, base station load, backhaul load and backhaul delay.

Analytics driven wireless device session context handover in operator cloud

A method in a base station for selecting a transport format is provided. The base station allocates resources to a User Equipment, UE. When a first criterion is fulfilled for the allocated resources, the base station estimates Signal-to-Interference-plus-Noise Ratio, SINR, by using a first gain offset. The first gain offset relates to a resource allocation according to the first criterion. When a second criterion is fulfilled for the allocated resources, the base station estimates SINR by using a second gain offset. The second gain offset relates to a resource allocation according to the second criterion. The base station then selects a transport format for the allocated resources based on the estimated SINR.
