Methods and apparatuses are disclosed for communicating a hybrid user equipment with an Internet server, whereby a hybrid access gateway receives a multi-path request from a user plane system, transmits the multipath request toward an Internet server, and receives a corresponding response from the Internet server. If the received response is a single-path response, the hybrid access gateway assumes the Internet server does not support multi-path, activates a proxy function for the session and transmits a multi-path response for the received single-path response toward the user plane system, and the latter marks transmitting further multi-path requests for this session toward the hybrid access gateway. If the received response is a multi-path response, the hybrid access gateway assumes the Internet server supports multi-path, deactivates a proxy function for the session and transmits the received multi-path response toward the user plane system, and the latter marks bypassing the hybrid access gateway for further multi-path requests for this session.
