    • The invention proposes a method for controlling a connection between a first network node and a second network node, wherein the connection is controlled by a packet filtering function filtering packets such that a packet is discarded in case a source address and/or a destination address do not comply with a filtering rule, wherein the packet filtering function is configured at a connection set up, and at least one of the first or second network node is adapted to change its address, the method comprising the steps of informing the packet filtering function about the new address of the network node having changed its address, and updating the packet filter of the packet filtering function by using the new address of the network node having changed its address. The invention also proposes a corresponding network system comprising at least a network node and a packet filtering network element. Furthermore, the invention proposes a corresponding packet filtering network device.

    • The invention proposes a method for providing traversal of a packet filtering function (D) for information transferred between a first network node (A) and a second network node (B) wherein the second network node (B) is associated with a home network control element (C) and the first network node (A) is protected by the packet filtering function (D), the method comprising the steps of sending (S1) a message including temporary identification information from the second node to the home network control element, sending (S3) a message including at least a part of the temporary identification information from the home network control element to the first node, and preparing (S4-S7) a direct connection between the first node and the second node via the packet filtering function based on the identification information. The invention also proposes corresponding network nodes, a corresponding home network control element and a corresponding network system.

    • Communications systems and methods for controlling transportation of data. The methods commonly include entering state information associated with a data transportation connection in a state information record maintained in a data processing entity. The data transportation connection is normally established between user equipment and a node, commonly via a gateway node, and the data processing entity is typically configured to control transportation of data based on the state information table. The methods also usually include, detecting that the data transportation connection is deactivated for the user equipment, sending information from the gateway node that the user equipment cannot be reached, and, in response to the information, deleting the state information from the state information record. The systems generally allow for implementation of the methods.
    • 用于控制数据传输的通信系统和方法。 这些方法通常包括在维护在数据处理实体中的状态信息记录中输入与数据传输连接相关联的状态信息。 通常通过网关节点在用户设备和节点之间建立数据传输连接,并且数据处理实体通常被配置为基于状态信息表来控制数据传输。 该方法还通常包括:检测到用户设备的数据传输连接被停用,从网关节点发送不能到达用户设备的信息,并且响应于该信息,从状态信息记录中删除状态信息 。 系统通常允许实现方法。
