Keep pagination after action

Hello,

I have a functionnal pagination. But i have a tab with lines and buttons and when i click on this button ( this button was link to other action in controller), i go to the first page of my pagination.

for exemple i am on the 4 pagination page and when i click on this button, this function was achieve and after this i was redirect on the 1rst page of the pagination...

How to be redirected on the same page ? i think i need use session and i have the number of the page, but how use it ??

My action is :

public function activate($id) {

        $valActiver = \App\Models\Point::find($id);

        if ($valActiver->active == 1) {
            $test = \DB::table('Point')
                    ->where('pointID', $id)
                    ->update(array('active' => '0', 'updated_at' => date('Y-m-d H:i:s')));
        } else {
            $test = \DB::table('Point')
                    ->where('pointID', $id)
                    ->update(array('active' => '1', 'updated_at' => date('Y-m-d H:i:s')));
        }

        $page = \Session::all();
        
        $urlPrec = $page['_previous']['url'];
        $monNumPage = parse_url($urlPrec);

        if(array_key_exists('query',$monNumPage)){
            $monNumPage = str_replace('page=', '', $monNumPage['query']);
        }
        
        return \Redirect::action('DotsController@index');

}


 public function index() {
        $titre = "Dots";
        $titreinfos = DotsController::TITREINFOS;
        $infos = DotsController::INFOS;
        $plansChoix = \DB::table('Plan')->lists('name', 'planID');

        $points = \DB::table('Point')
                ->leftjoin('Network', 'Network.networkID', '=', 'Point.networkID')
                ->leftjoin('TPoint', 'TPoint.tpointID', '=', 'Point.tpointID')
                ->orderBy('Point.pointID', 'asc')
                ->paginate(30, array('Point.pointID', 'Point.active', 'Point.name', 'Network.label as netlab', 'TPoint.label as tplab'));
        
        $networks = \DB::table('Network')->lists('label', 'networkID');
        $types = \DB::table('TPoint')->lists('label', 'tpointID');       
        
        return view('networkDots', compact('points', 'networks', 'types', 'titre', 'infos', 'titreinfos', 'plansChoix'));
    }

And in my routes.php

Route::get('dots/{id}', 'DotsController@activate');
Route::get('dots', 'DotsController@index');
Route::get('dotsFilter', 'DotsController@filter');

And this is a part of my view :

<table class="table table-striped mon-tab-avec-photo">
                <thead>
                    <tr>
                        <th class="noMobile">#</th>
                        <th>Name</th>
                        <th class="noMobile">Network</th>
                        <th class="noMobile">Type of path</th>
                        <th class="noMobile">Activated</th>
                        <th>Infos</th>
                    </tr>
                </thead>

                <tbody>
                    
                   
                    @foreach($points as $point)
                    <tr>
                        <td class="zonePourLaCouleur noMobile">{{ $point->pointID }}</td>
                        <td class="zonePourLaCouleurMobile">{{ $point->name }}</td>
                        <td class="noMobile">{{ $point->netlab }}</td>
                        <td class="noMobile">{{ $point->tplab }}</td>
                        <td class="noMobile">
                            @if($point->active == 0)
                                {!! HTML::linkAction('DotsController@activate', 'Activer', array($point->pointID), array('class' => 'buttonActiveDesa')) !!}
                            @else
                                {!! HTML::linkAction('DotsController@activate', 'Desactiver', array($point->pointID), array('class' => 'buttonActive')) !!}
                            @endif
                        </td>
                        <td>{!! HTML::linkAction('DotsController@infos', ' ', array($point->pointID), array('class' => 'buttonEdit')) !!}</td>
                    </tr>
                    @endforeach
 
                </tbody>

            </table>
            
            {!! str_replace('/?', '?', $points->render()) !!}

Thank
