    • A method of configuring a network access device having a first network address allocated to a subscriber of services of a first service provider provided by a first service network, with a new network address allocated to a subscriber of services of a second service provider provided by a second service network, wherein the network access device is connected to an access network connected to a plurality of service networks. The method comprises the steps of: sending a request from the network access device to the access network requesting a change to a second service provider; receiving a response from the access network; and initiating a network address change request using a configuration protocol. In this manner, a second network address allocated to the subscriber of services of the second service provider is assigned to the network access device to enable the network access device to communicate data packets to the service network providing the selected service. In one preferred embodiment of the invention, the subscriber is authenticated by a service activation system coupled to the access network prior to initiating the configuration protocol. Accordingly, the request to the access network includes an authentication request for the subscriber. The response received from the access network therefore includes an authentication status for the subscriber from the second service provider. If the subscriber is authenticated, the client initiates the network address change request.
    • 一种配置网络接入设备的方法,所述网络接入设备具有分配给由第一服务网络提供的第一服务提供商的服务的订户的第一网络地址,以及分配给由第二服务提供商提供的服务的服务的订户的新网络地址 第二服务网络,其中所述网络接入设备连接到连接到多个服务网络的接入网络。 该方法包括以下步骤:从网络接入设备向接入网发送请求对第二服务提供商的改变的请求; 从接入网接收响应; 以及使用配置协议发起网络地址改变请求。 以这种方式,分配给第二服务提供商的服务的订户的第二网络地址被分配给网络接入设备,以使得网络接入设备能够向提供所选服务的服务网络传送数据分组。 在本发明的一个优选实施例中,在启动配置协议之前,用户被耦合到接入网络的服务激活系统认证。 因此,对接入网络的请求包括用户的认证请求。 因此,从接入网接收的响应包括来自第二服务提供商的用户的认证状态。 如果用户被认证,客户端发起网络地址更改请求。
