Abstract: Methods and apparatus, including computer program products, are provided for user-plane switching of traffic for dual connectivity. In some example embodiments, there is provided a method. The method may include receiving, at a serving gateway, an indication to persist a first tunnel identifier located at a master base station, while the serving gateway sends, towards a second tunnel identifier located at a secondary node, user plane traffic for a user equipment in dual connectivity with the master base station and the secondary node; and switching, at the serving gateway, the user plane traffic between the second tunnel identifier and the first tunnel identifier, when the serving gateway receives, via a user plane, an error indication and/or a switch indication. Related apparatus, systems, methods, and articles are also described.
