    • The method for managing menu functions in a mobile station includes the steps of executing menu edition, selecting menu items the user uses frequently in the executed menu edition, to set up a menu, executing the menu, and displaying the menu of the selected menu items at first. The basic menu inclusive of all menu items the mobile station provides is selected as a last menu item of the mode menu displayed at first so that the user can access to menu items other than the menu items of preference. By providing easy mode menu with menu items the user or manufacturer of the mobile station uses frequently in advance, and displaying on a display window at first, the user is permitted a quick and easy access to a desired menu item without going through many steps of menus for using the desired menu item.
    • 用于管理移动站中的菜单功能的方法包括以下步骤:执行菜单编辑,在执行的菜单版本中选择用户频繁使用的菜单项,设置菜单,执行菜单,以及显示所选菜单项的菜单 首先。 选择包括移动台提供的所有菜单项的基本菜单作为首先显示的模式菜单的最后菜单项,以便用户可以访问除了优选菜单之外的菜单项。 通过提供具有菜单项的简单模式菜单,移动站的用户或制造商预先使用频率,并且首先在显示窗口上显示,允许用户快速且容易地访问期望的菜单项,而不经过许多步骤 使用所需菜单项的菜单。
