  • Patent number: 9693372
    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.

  • Patent number: 9667568
    Abstract: A method of detecting physical connections between a root bridge node and layer-2 bridge nodes organised in a layer-2 cloud. The method comprises sending a query message from a sending port of the root bridge node and starting a timer set to a waiting interval. After the timer expired, if a response message to the query message is not received or is received at the sending port then only the sending port is associated with said layer-2 cloud. Alternatively, if a response message is received at a port other than the sending port then the sending port and the receiving port are associated with said layer-2 cloud. A bridge node and a layer-2 communications network are also disclosed.
