摘要： For the purpose of selecting a base station (110, 120) to be used as a serving base station of a mobile terminal (100), a traffic characteristic of the mobile terminal (100) is determined. The traffic characteristic may in particular be indicative of an asymmetry between downlink and uplink data traffic of the mobile terminal (100). On the basis of the traffic characteristic, a selection between a first mode and a second mode is performed. In the first mode the base station (110, 120) to be used as the serving base station is selected on the basis of its downlink radio capacity as compared to one or more other base stations (110, 120). In the second mode the base station (110, 120) to be used as the serving base station is selected on the basis of its uplink radio capacity as compared to one or more other base stations (110, 120).

摘要： A method and an arrangement (500) in a radio network node (130) for redistributing resources between at least a first and second communication device (110, 120) are provided. The radio network node (130) obtains a first estimate of a first signal quality for the first communication device (110) and a second estimate of a second signal quality for the second communication device (120). The radio network node (130) determines a first required signal quality for the first communication device (110) and a second required signal quality for the second communication device (120). When the first required signal quality is less than the first estimate and the second required signal quality is greater than the second estimate, the radio network node (130) allocates resources to the first and second communication devices (110, 120) such that the first signal quality decreases and such that the second signal quality increases.

摘要： Packets are selectively marked or dropped when congestion of the radio resources is experienced, the selective marking/dropping being related to or dependent on the probability that a packet will be marked with the relative efficiency of usage of the radio link by the receiver, e.g., dependent upon radio resource usage costs and fairness. For example, packets are marked or dropped based on a user's associated share of the total (or a subset of the) shared radio resources. This share may be expressed in terms of the costs of the resources in terms the user's level of utilization of the shared resources, or in terms of it's fairness with respect to other users sharing the same resources. Thus, the present technology takes into account the distribution of resources usage between receivers contributing to the congested state of the radio network.
摘要翻译：当无线电资源的拥塞经历时，选择性地标记或丢弃分组，选择性标记/丢弃与分组将以接收机的无线电链路的使用的相对效率被标记的概率相关联，取决于无线电资源使用成本和公平性。例如，基于用户的总共（或一部分）共享无线电资源的关联共享来标记或删除数据包。这个份额可以用资源的成本来表达，用户对共享资源的利用水平，或者在共享相同资源的其他用户方面是公平的。因此，本技术考虑到对无线电网络的拥塞状态有贡献的接收机之间的资源使用的分配。
