摘要： Methods, arrangement and network nodes for supporting inter-cell coordination of scheduling of radio resources subjected to inter cell interference. The methods involve identifying one or more radio resources which are subjected to inter-cell interference between a first cell and a second cell. The methods further involve deriving a respective service value related to service that could be provided in the respective first and second cell by use of the one or more radio resources. Further, transmissions in the one or more radio resources are controlled based on comparison of the service values, thus enabling inter-cell service value-based scheduling of the one or more radio resources, prioritizing services having the highest value per radio resource.

摘要： A method in a first radio network node (105, 110, 120) for handling positioning of a first user equipment (110) is provided. The first radio network node (105, 110, 120) defines a criterion relating to at least one measurable radio quality of the first user equipment (110). The criterion is based on historical measurements of the at least one radio quality of at least one second user equipment having experienced a radio event. Fulfilment of the criterion is an indication that the radio event is upcoming for the first user equipment (110). The first radio network node (105, 110, 120) receives a current measurement of the at least one radio quality of the first user equipment (110), for which first user equipment (110) the radio event is currently upcoming. When the criterion is fulfilled, the first radio network node (105, 110, 120) triggers positioning of the first user equipment (110).

摘要： The present invention relates to a method and a communication network node for automatically tuning a PRACH configuration parameter in a communication network system comprising radio base stations each serving at least one cell and with which user equipments are communicating on uplink and downlink channels. The PRACH configuration parameter is used for defining the division of uplink resource blocks between PRACH and PUSCH. Load statistics on RACH and PUSCH are collected used for determining a number of RACH opportunities required per time unit. Then a new PRACH configuration parameter having said required number of RACH opportunities per time unit is selected which is replacing the old PRACH configuration parameter.

摘要： The invention relates to a method for service aware scheduling of wireless resources in a wireless network. According to the inventive method, a service request for service delivery of a service type is received (51). A performance to value relationship for the service type is determined (52) and approximated (53) with a scheduling weight function associated with the service type. Previous performance for service delivery related to this service request is evaluated and approximated with a performance estimate (54). A scheduling weight is determined (55) by introducing the performance estimate in the scheduling weight function. Resource scheduling is performed (58) following a step of comparing (56) scheduling weights for on-going service requests. The invention also includes a network node and a system for service aware scheduling of wireless resources in a wireless network.

摘要： Handover (HO) statistics and handover issue events which are due to non-mobility causes are not included in the statistics fed into mobility robustness optimization (MRO). The non-mobility causes may include, e.g., load balancing, retracting users to prepare for cell maintenance or restart/reconfiguration and cell outage including compensation means. Radio link failure (RLF), handover failure (HOF), and handover oscillations (HOosc) that are due to non-mobility cause are excluded from the statistics upon which mobility robustness optimization is based. Non-mobility causes are also differentiated from mobility causes when reporting key performance indicators to an operator.
摘要翻译： 归因于移动性原因的移交（HO）统计和切换问题事件不包括在馈送到移动性鲁棒性优化（MRO）中的统计信息中。 非移动性原因可以包括例如负载平衡，缩回用户以准备小区维护或重新启动/重新配置以及包括补偿装置的小区中断。 基于移动性鲁棒性优化的统计信息中排除由于非移动性原因导致的无线电链路故障（RLF），切换失败（HOF）和切换振荡（HOosc）。 在向运营商报告关键绩效指标时，非流动性因素也与移动性原因不同。
