At a network element, a first TEID is determined that is associated with a default bearer between a UE and a first APN. A determination is made whether a tunnel discovery procedure should be performed to discover a second TEID associated with a dummy bearer. The dummy bearer is associated with the UE and a second APN. The tunnel discovery procedure is performed to discover the second TEID, and the dummy bearer is set up between the network element and the UE. Data arriving at the network element from the core network and toward the UE is routed over one of the default bearer, using the first TEID, or the dummy bearer, using the second TEID. Data arriving at the network element from the UE and toward the core network is routed over only over the default bearer. Apparatus, methods, and computer programs and products are disclosed.
