That depends on what hardware and/or which LoRaWAN stack you are using. You need to provide more details for anyone to be able to provide the answer you are looking for. Links to the components used are useful…

There’s actually no such thing as “joining” in ABP. You just send packets with the right keys and a non-rewound, not-too-far-in advance frame count.

But many ways of restarting your node might have lost this information. If you can get it from TTN, perhaps you can build a suitable starting point into your node.

Only ADR really has a sense of a live “session” but it is confined to the ramped up data rate, not the basic crypto / frame count state.
