Abstract
Methods and apparatuses for detection of session status are disclosed. According to an embodiment, a user plane (UP) of a base station receives, from a control plane (CP) of the base station, a request for releasing at least one bearer for a terminal device. The request comprises time information usable for deriving a first time at which the at least one bearer was detected by the CP of the base station as needing to be released. The UP of the base station determines a session status of the at least one bearer based on the time information and sends, to the CP of the base station, a response to the request. The response comprises the determined session status of the at least one bearer.
