Claim 0:
1. A method performed by a first network node, for deciding a configuration to be used in a data communication between the first network node and a second network node in a wireless communications network, the method comprising:
receiving a second message from the second network node, the second message including user plane configuration information including a vendor identity corresponding to a vendor owning the second network node, a highest user plane protocol version that is supported by the second network node, and a set of proprietary features of the vendor that are supported by the second network node, the second message being conveyed by using a frame structure according to a protocol specification that is being negotiated;
sending a first message to the second network node, the first message comprising vendor information of the first network node, and the first message triggering the second network node to respond with the user plane configuration information related to the second network node, the second message being received as a response to the first message, the first and second messages being signaled in a respective General Packet Radio Service, GPRS, Tunneling Protocol-User plane, GTP-U data frame; and
deciding a user plane vendor configuration to be used in the data communication between the first network node, the second network node, the user plane vendor configuration being based on:
the received information in the second message and a vendor identity of the first network node, a highest user plane protocol version that is supported by the first network node and a set of proprietary features that are supported by the first network node.
