    • The present invention relates to provision of data bearers in a communication system (2) comprising a first node (1) and a second node (4). A message is generated that associates with provision of control of a data bearer between the nodes (1,4), said message being based on a data bearer control protocol. Information that associates with responsibilities regarding a quality of service function of the data bearer is included in the message. The message is then transported between the nodes (1,4). The quality of service function of the data bearer is controlled by a control node (1,16) that has been selected based on said information added in the message.
    • 本发明涉及在包括第一节点(1)和第二节点(4)的通信系统(2)中提供数据承载。 生成与提供节点(1,4)之间的数据承载的控制相关联的消息,所述消息基于数据承载控制协议。 与消息中包含关于数据承载的服务质量功能的责任有关的信息。 然后在节点(1,4)之间传输消息。 基于在消息中添加的所述信息已被选择的控制节点(1,16)来控制数据承载的服务质量。

    • A method of relocating the header compression context in a packet network which transmits packets having compressed headers. A connection is established between a mobile terminal and a first network entity and context information used with compression and decompression of the headers of the packets is stored at the mobile terminal and the first network entity. The context information updating is stopped in the mobile terminal and in the first network entity and after that, a snapshot of the compression and decompression context information is taken and stored in the first network entity. The connection between the first network entity and the mobile terminal is changed to a connection between the mobile terminal and a second network entity. The context information snapshot stored by the first network entity is transferred to the second network entity to be stored therein as the context information of the second network entity. The stored context information at the mobile terminal and the second network entity is then used for compression and decompression of the headers of the packets.
    • 在发送具有压缩报头的分组的分组网络中重新定位报头压缩上下文的方法。 在移动终端和第一网络实体之间建立连接,并且在移动终端和第一网络实体处存储与分组的报头的压缩和解压缩一起使用的上下文信息。 在移动终端和第一网络实体中停止上下文信息更新,之后,采集压缩和解压缩上下文信息的快照并将其存储在第一网络实体中。 第一网络实体和移动终端之间的连接被改变为移动终端与第二网络实体之间的连接。 由第一网络实体存储的上下文信息快照被传送到第二网络实体以作为第二网络实体的上下文信息存储在其中。 然后,在移动终端和第二网络实体处的存储的上下文信息被用于分组报头的压缩和解压缩。

    • A data packet transmission method in a packet-switched telecommunication system. A telecommunication protocol comprises a convergence protocol layer for adapting user data packets to convergence protocol packets and a link layer for transmitting the convergence protocol packets as data units and for acknowledging the transmission. A data packet number is defined for the convergence protocol packets to be transmitted. The convergence protocol packets are transferred to the link layer to be transmitted. A data packet number is defined for the received convergence protocol packets and the received convergence protocol packets are acknowledged to the transmitter. The identification data of any convergence protocol packets lost on the link layer are transmitted to the recipient. The counter value of the recipient is updated to correspond to the counter value of the transmitter, to take into account the lost convergence protocol packets.
    • 分组交换电信系统中的数据分组传输方法。 电信协议包括用于将用户数据分组适配到汇聚协议分组的汇聚协议层,以及用于发送汇聚协议分组作为数据单元并用于确认传输的链路层。 定义要发送的会聚协议数据包的数据包号。 汇聚协议报文被传送到要发送的链路层。 为收到的汇聚协议报文定义数据报文号,接收到的收敛协议报文被确认给发送端。 在链路层丢失的任何收敛协议分组的标识数据被发送给接收方。 接收者的计数器值被更新为对应于发射机的计数器值,以考虑丢失的会聚协议分组。
