    • A method is provided for providing a possibility of starting a communication session from a public or global data network, such as the Internet, to a private or local data network, such as a residential home network, via a gateway device (18) connecting the public and the private network. The gateway device comprises a Network Address Translation (NAT) functionality, concealing for the public network the addressing realm of the private network, but also customarily blocking the starting of sessions from the public network. According to the method provided, a client device (10) connected to the public network can provide the possibility of starting a session to a server device (14) connected to the private network by performing an explicit remote access request directed toward the server device, involving the exchange of remote access request messages (20, 22) between the client, gateway, and server devices. At the server device, the request triggers a related remote access response directed at the client device, similarly involving the exchange of remote access response messages (24, 26) between the devices. As a result of these message exchanges, an appropriate NAT address binding can be established at the gateway device, allowing the subsequent starting of a session by the client device.
    • 提供一种方法,用于经由网关设备(18)提供将诸如因特网之类的公共或全球数据网络的通信会话开始到私人或本地数据网络(例如住宅家庭网络)的可能性,网关设备(18) 公共和私人网络。 网关设备包括网络地址转换(NAT)功能,为公共网络隐藏专用网络的寻址领域,但也通常阻止从公共网络开始会话。 根据提供的方法,连接到公共网络的客户端设备(10)可以通过执行指向服务器设备的显式远程访问请求来提供与连接到专用网络的服务器设备(14)开始会话的可能性, 涉及在客户端,网关和服务器设备之间交换远程访问请求消息(20,22)。 在服务器设备处,请求触发针对客户端设备的相关远程访问响应,类似地涉及在设备之间的远程访问响应消息(24,26)的交换。 作为这些消息交换的结果,可以在网关设备处​​建立适当的NAT地址绑定,从而允许由客户端设备随后开始会话。

    • This invention relates to a system and method of providing conditional access to a data content item for a number of users, where the data content item is associated with a digital right that provides a user the right to access the data content item a predetermined number of times. The data content item is arranged in a number of subparts and the digital right is arranged in a number of sub-rights (100), initially designated as available sub-rights (101), where each available sub-right (101) provides a user the right to access a subpart of the data content item. When a user is granted (new) access to a content item a number of available sub-rights (101) is reserved. In this way, it is ensured in a very simple way that if a user in a multi-user scenario pauses access (also for a prolonged time) to the data content item then there will be sub-rights available so that the content may be accessed at a later time even if another user of the group starts spending sub-rights immediately after.
    • 本发明涉及一种向多个用户提供对数据内容项的条件访问的系统和方法,其中所述数据内容项与数字权利相关联,所述数字权利向用户提供访问所述数据内容项的预定数量的 次 数据内容项被排列在多个子部分中,并且数字权利被排列成多个子权利(100),最初被指定为可用子权限(101),其中每个可用子权利(101)提供 用户有权访问数据内容项的子部分。 当用户被授予(新)对内容项目的访问时,保留若干可用子权限(101)。 以这种方式,以非常简单的方式确保如果多用户场景中的用户暂停对数据内容项的访问(也是长时间),则将存在可用的子权利,使得内容可以是 即使该组织的另一个用户立即开始支付子权利,也可以在稍后访问。
