    • A virtual private network has an internal secured portion which connects to an external portion, the network via at least a first gateway and via a second gateway. There are a plurality of workstations including at least one mobile workstation in the external portion. The network automatically changes the point through which the mobile workstation communicates with the internal portion of the network from the first gateway to the second gateway, in response to movement of the mobile workstation. Context information is transferred to the second gateway. The context information includes an identifier of the mobile workstation and may also include material for defining secure communication means by which information is transferable securely between the mobile workstation in the external portion of the network and the internal portion of the network, via the second gateway.

    • The present invention relates to a policy resolution method and system, access network and terminal device for enabling modular network-assisted policy resolution, wherein the policy resolution is divided into separate stages each handling specific types of trigger events and performing specific types of policy actions. The separate stages are processed in a chronological order during a policy resolution round, and trigger events which occur during a policy resolution round are frozen until the start of the next policy resolution round. Thereby, modular policy resolution with reduced delays and oscillations can be achieved. Moreover, policy processing can be divided into a policy decision point functions in the network and a policy enforcement point function in the network or terminal device, so that terminal resources used for policy resolution can be saved.
    • 本发明涉及一种用于实现模块化网络辅助策略解决的策略解决方法和系统,接入网络和终端设备,其中策略解决方案被分成各自处理特定类型的触发事件并执行特定类型的策略动作的各个阶段。 单独的阶段在策略解决循环期间按时间顺序进行处理,并且在策略解决循环期间发生的触发事件被冻结直到下一个策略分辨率循环开始。 因此,可以实现具有减少的延迟和振荡的模块化策略分辨率。 此外,策略处理可以分为网络中的策略决策点功能和网络或终端设备中的策略执行点功能,从而可以节省用于策略解析的终端资源。

    • The present invention discloses a method for smart buffering for a policy resolution and policy enforcement system. The invention can be applied to a communication system with one or several available communication network(s). The trigger events and policy actions form input and output buffers to be processed in the invention. Causal relationships between the trigger events and policy actions are stored. Priorities can be set to the trigger events and policy actions. Sorting is made according to priorities. The buffer data can be scheduled, in other words delayed, in order to rationalize the policy management. The buffer data is combined if several trigger events affect the same target or quantity. The buffer data is filtered in the last step in order to simplify chained trigger events. The trigger events of filtered input buffer are sent to the policy resolution mechanism and the policy actions of filtered output buffer are sent to the policy action enforcement.
    • 本发明公开了一种用于政策解决和策略执行系统的智能缓冲的方法。 本发明可以应用于具有一个或多个可用通信网络的通信系统。 触发事件和策略动作形成在本发明中要处理的输入和输出缓冲器。 存储触发事件和策略动作之间的因果关系。 优先级可以设置为触发事件和策略动作。 排序是根据优先级进行的。 缓冲区数据可以安排,换句话说是延迟的,以便使策略管理合理化。 如果几个触发事件影响相同的目标或数量,则缓冲区数据被组合。 缓冲区数据在最后一步进行过滤,以简化链接触发事件。 过滤输入缓冲区的触发事件发送到策略解析机制,并将过滤的输出缓冲区的策略动作发送到策略动作执行。
