Angularjs ui-router angular-permission optional query string parameters

I need to have two optional parameter passed by url using the query string, I was able to reach this using ui-router ( plunker ) but is not working in mine application based on angular-permission for handling Authorization.

My stateChangeStart, stateChangeError and stateChangeSuccess are almost empty (I have only logs) since the permission is handled directly from the angular-permission library.

the state definition where i need this parameter is:

 $stateProvider
         .state('schedule', {
              url: "/schedule?param1&param2",
              views: {
                        'header': {
                            templateUrl: "common/partials/header.tpl.html",
                            controller: "HeaderCtrl"
                          },'content': {
                             templateUrl: "schedule/partials/schedule.tpl.html",
                             controller:"ScheduleRecapCtrl"
                      }
              },
               resolve:{
                     Filters:'Filters',
                          availableFilters:function(Filters){
                                  return Filters.get().$promise;
                      }
               }, data: {
                         permissions: {
                              only: ['logged'],
                              redirectTo: 'login'
                          }
                }
              })

this is mine groups definition

 app.run(function (PermissionStore, authenticationSvc) {
    // Define anonymous permission
    PermissionStore.definePermission('anonymous', function(stateParams){
            return !authenticationSvc.isLogged();
    });
    PermissionStore.definePermission('logged', function (stateParams) {
            return authenticationSvc.isLogged();
    });

I noted that after reaching the state with the parameters a new $stateChangeStart is triggered (before the $stateChangeSuccess) but without the parameters that comes from the url. I don't know if there are mistake in the state definition or if the angular-permission is doing something not correct.
