    • In a method and apparatus for applying a background skin in an Internet protocol (IP) network, a first terminal sends a call request message, including background skin index information, to a second terminal. The second terminal sends a response message, including background skin index information, to the first terminal in response to the received call request message. The first terminal and the second terminal separately receive and display background skin data transmitted between the first terminal and the second terminal, and display multimedia data transmitted and received during a session established between the first terminal and the second terminal, together with the background skin displayed on each terminal.
    • 在用于在互联网协议(IP)网络中应用背景皮肤的方法和装置中,第一终端向第二终端发送包括背景皮肤索引信息的呼叫请求消息。 响应于所接收的呼叫请求消息,第二终端向第一终端发送包括背景皮肤索引信息的响应消息。 第一终端和第二终端分别接收和显示在第一终端和第二终端之间传输的背景皮肤数据,并且显示在第一终端和第二终端之间建立的会话期间发送和接收的多媒体数据以及显示的背景皮肤 在每个终端。

    • To support authentication of a mobile device, an application server obtains an application identifier and password and creates an encrypted value by encrypting a combination of the password and a time-based value. The application server transmits the application identifier and encrypted value over a communication network to the mobile device as a credential, and the mobile device sends the credential over the network to a secure server providing an application assistance service. The secure server independently computes an encrypted value by encrypting the combination of the password and the time-based value. If the encrypted value from the received credential matches the encrypted value computed by the secure server, that server grants access to the assistance service for the mobile device.
    • 为了支持移动设备的认证,应用服务器获得应用标识符和密码,并通过加密密码和基于时间的值的组合来创建加密值。 应用服务器通过通信网络将应用标识符和加密值作为凭证发送到移动设备,并且移动设备通过网络将证书发送到提供应用辅助服务的安全服务器。 安全服务器通过加密密码和基于时间的值的组合来独立地计算加密值。 如果来自接收到的凭证的加密值与由安全服务器计算的加密值相匹配,则该服务器授予对移动设备的辅助服务的访问权限。
