摘要： Communication systems, such as an evolved packet system, may benefit from optimizations for frequent small data transmissions. In particular, certain communication systems in which mobile applications require numerous keep-alive messages or presence information may benefit from optimizations to state transitions between active and idle states. A method may include detesting a plurality of small packets that are mobile terminated. The method may also include indicating an inactivity time based on the detecting of the small packets and providing this indication in user plane packets or control signaling to the radio access network.

摘要： In a communication network, which includes a call control level CCL, a resource control level RCL and at least one terminal A assigned to data transfer, a QoS requirement RQ determined for a data transfer is verified at expense at call control level CCL. An encrypted token T is then created from this and transferred via terminal A to resource control level RCL. This latter verifies an incoming QoS requirement RQ from terminal A only by means of the encrypted token T. If successful, the communication network is configured so that the data is transferred with the QoS verified according to the invention. The invention allows the efficient, secure and correct provision of QoS in integrated voice and data networks. In particular extensive modifications to existing routers are avoided at resource control level RCL. The regularly repeated transfer of tokens T also supports consistent termination of the QoS provided and secure and correct billing of the data transfer.
摘要翻译：在包括呼叫控制级CCL，资源控制级RCL和分配给数据传输的至少一个终端A的通信网络中，在呼叫控制级CCL处以费用验证对数据传送确定的QoS要求RQ。然后从其创建加密令牌T，并通过终端A传送到资源控制级别RCL。后者通过加密的令牌T验证来自终端A的输入QoS要求RQ。如果成功，则配置通信网络，使得根据本发明验证的QoS传送数据。本发明允许在集成语音和数据网络中有效，安全和正确地提供QoS。特别是在资源控制级别RCL中避免了对现有路由器的广泛修改。定期重复传输令牌T还支持一致地终止提供的QoS，并确保和正确计算数据传输。
