摘要： The embodiments disclosed relates to a method and a network node that determines a time period between a first handover and a second handover of a user equipment. The first handover is to or from a first cell and the second handover is to or from a second cell. The network node sets a threshold value based on a difference in cell quality between the first cell and the second cell. The difference in cell quality is associated with the first or second handover. The network node then determines the type of handover, of at least one of the first and second handover, based on the time period and threshold value.

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。

摘要： The present invention relates to an arrangement, a communication network node and a user equipment allowing for probing of alternative antenna configurations in a communication network system as well as a method for such probing. The method comprises making one of the reconfigurable antennas (15a2, 15b2) of at least one cell (19a, 19b) temporarily available for probing and reconfiguring one or more antenna parameters thereof in accordance with a probing antenna parameter set. A new probe cell (20a, 20b) is transmitted from the prepared antenna (15a2, 15b2) and measurement reports collected from the user equipments (18) within the at least one cell (19a, 19b) and the probe cell (20a, 20b). The probing antenna parameter set is evaluated based on the collected measurement reports whereupon is determined if the reconfigurable physical antennas (15a1, 15a2, 15b1, 15b2) of the cell shall use the probing antenna parameter set or the initial antenna parameter set. Finally the probing cell (20a, 20b) is removed and the antennas (15a1, 15a2, 15b1, 15b2) adjusted in accordance with the determination.

摘要： In a method and an apparatus for determining when a cell of a cellular radio system can enter a discontinuous transmission mode is provided. By evaluating qualities from both the cell and neighboring cells for a number of positions and calculating a statistically expected quality distribution of the evaluated qualities conditioned on that certain cells are in discontinuous transmission mode it is possible to generate a distribution which can be compared with at least one requirement thresholds. Based on the comparison it is possible to determine if first cell can use discontinuous transmission mode and still fulfill the requirements.

摘要： A method in, and a network node (110, 140), for supporting compensation of cell outage in a cellular communications network (100). The cellular communications network (100) comprises a compensating cell (135) for compensating the cell outage and a supporting cell (115) neighbouring the compensating cell (135). The network node (110, 140) obtains (502, 1202) a sub-band of a system bandwidth for uplink scheduling of resources for the compensating cell (135). The network node (110, 140) schedules (503, 1203), in response to the cell outage, resources for the supporting cell (115) with restricted uplink scheduling within the sub-band. The network node applies (504, 1204) the scheduled resources in the supporting cell (115), thereby supporting the compensation of cell outage. As a result, higher Signal to Interference and Noise Ratio (SINR) is enabled in the uplink in the compensating cell. This may e.g. be utilized to let the compensating cell cover a larger area of an outage cell than else would be possible, and/or to serve user equipments located therein with improved performance.

摘要： A method in a base station (110) for enabling the base station (110) to identify a neighbouring base station (120) is provided. A request is being sent (303) to a user equipment (130), commanding it to send an identification requesting message to the neighbouring base station (120). In response to reception of the sent identification requesting message, a neighbouring base station identifier that is associated with and identifies the neighbouring base station (120), is received (303). Thereby the base station (110) is enabled to identify the neighbouring base station (120). By receipt of the neighbouring base station identifier, the base station becomes aware of and is enabled to contact, or connect with, the neighbouring base station more directly, without the need of doing it through the user equipment. This can be done at some later point in time, for example in order to request the neighbouring base station to perform handover measurements with regard to the same or another user equipment.
摘要翻译：提供了一种用于使基站（110）能够识别相邻基站（120）的基站（110）中的方法。正在向用户设备（130）发送（303）请求，命令其向相邻基站（120）发送标识请求消息。响应于发送的标识请求消息的接收，接收与相邻基站（120）相关联并识别相邻基站（120）的相邻基站标识符（303）。因此，基站（110）能够识别相邻的基站（120）。通过接收到相邻的基站标识符，基站能够更直接地了解并且能够与相邻基站进行联系或连接，而不需要通过用户设备来进行。这可以在稍后的时间点完成，例如为了请求相邻基站对相同或另一个用户设备执行切换测量。

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： In a cellular radio system a message indicating a change of cell size can be transmitted to a number of affected cells, in particular, neighboring cells. The affected cells receiving such a message can be adapted to use the information in the message when determining self-optimization parameters used for control purposes. Hereby, better response times can be achieved without reducing noise sensitivity.

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.
