how to pass parameters to returnURL MVC

Question

Problem: Customer click 'Book' link and is redirected to the LogIn page.

 @Html.ActionLink("Book", "BookVisit", new { time = Model.availableTimesList[i].TimeOfDay, date = Model.dateOfAppointment, providerID = Model.providerID }) 

After loging in I would like him to be redirected to the page where he originally wanted to get. I use this code in custom Authorize Attribute:

protected override void HandleUnauthorizedRequest(AuthorizationContext filterContext)
{
     filterContext.Result = new System.Web.Mvc.RedirectResult("/UserAccount/LogIn/?ReturnUrl=" + filterContext.HttpContext.Request.Url.AbsolutePath+ "?" + filterContext.HttpContext.Request.QueryString);
}

but to this method:

[AuthorizeUser(AccessLevel = "User,Admin")]
public ActionResult BookVisit(DateTime time, DateTime date,int providerID)

get only first parameter. Why and how to pass all of them?
