Abstract
For managing multicast transmissions in a cellular network, a control plane module () of a gateway node () of the cellular network establishes one or more control plane sessions associated with the multicast transmissions. Further, a user plane module () of the gateway node () establishes one or more user plane sessions associated with the multicast transmissions. The control plane module () of the gateway node () indicates context information of the control plane session(s) to an external storage (). During a failure of the control plane module () of the gateway node (), the user plane module () of the gateway node () maintains the user plane session(s). After recovery from the failure of the control plane module () of the gateway node (), the control plane module () of the gateway node receives the context information from the external storage () and re-establishes at least one of the more control plane session(s) on the basis of the received context information.
