Abstract
A method in a radio access node performs a sleepy cell test which can determine a cell state for a cell served by a radio access node. Fulfilment of a predetermined triggering condition is detected in a radio access node. Following detection of the fulfilled triggering condition, one or more user equipment to be paged is determined. The radio access node initiates a page response timer period and performs paging of the user equipment until there is time out of the timer period or a page response is received from the one or more user equipment. The paging responses received while performing the step of paging the user equipment is assessed. A cell state alert message reflecting the result from the paging is generated and sent to a receiving entity. Related radio access nodes configured to carry out the sleepy cell test and methods are disclosed.
