1. A method in a network node, comprising:
establishing a first bearer between a local breakout function gateway, the local breakout function gateway collocated at the network node, and an application client of a wireless device;
transmitting network assistance information to the wireless device over the first bearer via application-layer signaling in the user plane, the network assistance information comprising information related to optimizing transmission of user data over a second bearer established between the wireless device and a core network node, wherein the second bearer is different than the first bearer; and
associating the application-layer signaling transmitted over the first bearer with the user data transmitted over the second bearer, wherein associating the application-layer signaling transmitted over the first bearer with the user data transmitted over the second bearer comprises:
receiving, from the application client of the wireless device, identification information enabling the network node to identify traffic related to the user data transmitted over the second bearer.
