Angular JS $location change promise

I am using angularJS $location service for routing change, the problem is $location.url(someUrl) is asynchronous but doesn't return promise. So I searched for some solution for this and found these events:

1) $scope.$on('$locationChangeSuccess') 2) $routeChangeStart 3) $routeChangeSuccess

but these events not happening for example when the URL provided to $location.url function is the same as current, I'm seeking for some robust solution to be ensured that $location.url has finished it's work
