forwarding in section resolve by RouteProvider to another view - angularjs

Question

I have a problem with the provider in AngularJS.
I would like to in any view to check whether the user is logged on. If not then it should redirect to / login. On the console, there is no error. I do not know what is wrong.
var app= angular.module("app", ["ngRoute", "ngAnimate", "ngResource"]);
app.config(["$routeProvider", "$locationProvider", function($routeProvider, $locationProvider) {
var getItemNameById = function($route, $location, service, breadcrumbs, path) {
service.getItem($route.current.params.id).then(function(evt) {
if(evt.title) {
$route.routes[path].label = evt.title;
} else if(evt.name) {
$route.routes[path].label = evt.name;
}
breadcrumbs.generateBreadcrumbs();
}, function() {
$location.path("/404");
});
};
$routeProvider
.when("/", {
template: "",
label: "Home",
resolve: function($q, $location) {
alert("in resolve Home...");
var deferred = $q.defer();
if (!isLoggedIn) {
$location.path('/login');
}
deferred.resolve();
return deferred.promise;
}
})
.when("/patient", {
templateUrl: "patient.html",
label: "Patient",
resolve: function($q, $location) {
alert("in resolve Patient...");
var deferred = $q.defer();
if (!isLoggedIn) {
$location.path('/login');
}
deferred.resolve();
return deferred.promise;
}
})
.when("/doctor", {
templateUrl: "doctor.html",
controller: "DoctorController",
label: "Doctor",
resolve: function($q, $location) {
alert("in resolve Home...");
var deferred = $q.defer();
if (!isLoggedIn) {
$location.path('/login');
}
deferred.resolve();
return deferred.promise;
}
});
}]);
app.run(["$rootScope", "LoginService", function($rootScope, LoginService) {
LoginService.checkSession().then(function(response) {
$rootScope.isLoggedIn = response;
}, function(reject) {
$rootScope.isLoggedIn = reject;
});
}]);
why not enter into sections resolve (alert also does not show) on the home page?
best regards

I think you should set a event to route change ,something like this:
app.run(function($rootScope) {
$rootScope.$on("$routeChangeStart", function(event, nextRoute, currentRoute) {
if (nextRoute != null ) {
//Check session
}
});
});
