Abstract
The embodiments herein relate to a method in an eNB for handling MBSFN area configuration information. The eNB receives, from a MME, a MBMS session start request. Based on the received request, the eNB computes a first time for a start of the MBMS session. The first time is a first MCC, update time. The eNB periodically sends, from the first time, the configuration information to a user equipment. The eNB stops the sending of the configuration information to the user equipment when the MBMS session is a last MBMS session. The eNB sends updated configuration information to the user equipment when the MBMS session is not the last MBMS session. The updated configuration information is updated MBSFN area configuration information.
