As long as session is unique per client-server communication, try this workaround:

var smpp = require('smpp');
var server = smpp.createServer(function(session) {
    if (typeof session.client !== 'undefined') {
        session.send(pdu.response({
            command_status: smpp.ESME_RBINDFAIL
        }));
        session.close();
        throw Error('Session already has "client" key');
    }
    // introduce new session var
    session['client'] = {
        system_id: ''
    };
    session.on('submit_sm', function(pdu) {
        console.log('client username is : ', session.client.system_id);
    });
    session.on('bind_transceiver', function(pdu) {
        // we pause the session to prevent further incoming pdu events,
        // untill we authorize the session with some async operation.
        session.pause();
        checkAsyncUserPass(pdu.system_id, pdu.password, function(err) {
            if (err) {
                session.send(pdu.response({
                    command_status: smpp.ESME_RBINDFAIL
                }));
                session.close();
                return;
            }
            // set client ID/username
            session.client.system_id = pdu.system_id;
            session.send(pdu.response());
            session.resume();
        });
    });
});
server.listen(2775);
