摘要： A method for ensuring continuity of a communication session when a user equipment hands over from a first communication network to a second cellular communication network is provided. The method, in one embodiment, includes the steps of performing an authentication procedure for a packet data session with the second network while still being attached to the first network and simultaneously performing a packet data session establishment procedure with the second network while still being attached to the first network.
摘要翻译：提供了一种用于当用户设备从第一通信网络切换到第二蜂窝通信网络时确保通信会话的连续性的方法。在一个实施例中，该方法包括以下步骤：在仍然附着到第一网络的同时执行与第二网络的分组数据会话的认证过程，并且同时在仍然被附加到第二网络的同时执行与第二网络的分组数据会话建立过程第一个网络。

摘要： A method for performing a change of a connection of a mobile entity from a first network access entity to a second network access entity, wherein a global address of the first network access entity is not known to the mobile entity is provided. According to one embodiment, the method includes the step of sending a message including information for identifying the first network access entity from the mobile entity to the second network access entity which enables the second network entity to direct traffic to the first network entity. According to another embodiment, the invention also provides a method for the reverse direction. Namely, the invention provides a method for sending IP signaling from the mobile entity or from the first network access entity towards the second network access entity, whose global IP address is not known by the mobile entity or first network access entity.
摘要翻译：一种用于执行移动实体从第一网络访问实体到第二网络接入实体的连接的改变的方法，其中提供了移动实体不知道第一网络接入实体的全局地址。根据一个实施例，该方法包括以下步骤：将包括用于识别第一网络接入实体的信息的消息从移动实体发送到第二网络接入实体，该第二网络接入实体使第二网络实体能够将业务指向第一网络实体。根据另一个实施例，本发明还提供了一种反向方法。即，本发明提供了一种从移动实体或从第一网络接入实体向第二网络接入实体发送IP信令的方法，该全球IP地址由移动实体或第一网络接入实体不知道。

摘要： The present invention relates to a method, routing device, and access device for forwarding a data packet with multicast purpose to a connection-oriented network, wherein a predetermined broadcast address is added to the data packet if the address of the data packet to be sent is a network-layer multicast address. Based on the broadcast address address, the data packet is forwarded to a plurality of access devices (31-3n) of the connection-oriented network, arranged to check whether the destination address of the data packet is supported. Then, the data packet is forwarded from a supporting access device (32) to the destination address. Thereby, the data packet does not have to be sent to every possible destination address one by one, and link capacity can be saved.
摘要翻译：本发明涉及一种方法，路由设备和接入设备，用于将面向组播的数据包转发到面向连接的网络，其中如果要发送的数据分组的地址将预定的广播地址添加到数据分组是一个网络层组播地址。基于广播地址，数据分组被转发到面向连接的网络的多个接入设备（31-3n），用于检查数据分组的目的地址是否被支持。然后，数据分组从支持接入设备（32）转发到目的地址。因此，数据包不必一个接一个地发送到每个可能的目的地址，并且可以节省链路容量。
