Restoration procedures in a Multimedia Broadcast Multicast Service (MBMS) network (also referred to as evolved MBMS (eMBMS) network) in case of a path failure.

MBMS session restoration in EPS for path failure

A method in a mobility management node for handling information in a network. The node is associated with a wireless device being served by a serving network. The node obtains information about that at least one of the serving network and a time zone and a UCI, has been changed for the device, and information about that the change has not been transmitted to a SGW. When at least one of the serving network and the time zone and the UCI, has been changed, and information about the change has not been transmitted to the SGW, the node transmits the information about at least one of the changed serving network and time zone and UCI, to the SGW, enabling the SGW to forward this information to a PGW.

Report of serving network, time zone, and UCI

The present invention relates generally to restoration procedures in a Multimedia Broadcast Multicast Service (MBMS) network (also referred to as evolved MBMS (eMBMS) network) in case of a path failure.

Report of serving network, time zone and UCI

The embodiments herein relate to a method in a mobility management node for handling information in a network. The node is associated with a wireless device being served by a serving network. The node obtains information about that at least one of the serving network and a time zone and a UCI, has been changed for the device, and information about that the change has not been transmitted to a SGW. When at least one of the serving network and the time zone and the UCI, has been changed, and information about the change has not been transmitted to the SGW, the node transmits the information about at least one of the changed serving network and time zone and UCI, to the SGW, enabling the SGW to forward this information to a PGW.

Report of servicing network, time zone and UCI

The embodiments herein relate to a method in a second CN node () for handling a failure in a communications network (). The failure has caused communication between the second CN node () and an old first CN node () to become unavailable. The communication is associated with a session. When the failure has been detected, the second CN node transmits a session start request message to a new first CN node (). The session start request is a request to restore the session. The session start request message comprises a restoration flag indicating restoration of the session for a same service established before the failure and allowing a RAN node () in the communications network () to accept the session start request message.
