Abstract: A 4G network node (and a method implemented thereby) and a terminal node (and a method implemented thereby) are described herein, all of which are configured to improve the probability of a SCG bearer setup by allowing the setup request to be sent to an alternative candidate SgNB (NR cell), in case it exists, instead of repeatedly persisting with the initial candidate SgB (BNR cell) after experiencing a predetermined number of SgNB addition request rejections or SCG failures.

Abstract: Embodiments described herein relate to a method and an apparatus for determining a first causal map for the root cause analysis of a primary event in a network environment.

Abstract: A system, method and non-transitory computer readable media for facilitating adaptive anchor layer mobility in a 5G NSA implementation. In one arrangement, a handover modulation criterion involving relevant trigger parametrics of an anchor cell node serving a UE and a target cell node may be compared against a tunable threshold parameter indicative of the effect of the target cell on the anchor cell quality. If the handover modulation criterion does not exceed the tunable threshold value, a quality degradation prediction with respect to the UE may be executed to estimate a likelihood of service failure for the UE. Responsive to determining that the likelihood of service failure does not exceed a probability threshold, handover of the UE to the target cell may be suppressed.

Abstract: The present application relates to a computer implemented method for managing connectivity of a wireless device in a cellular communication network, wherein the wireless device is operable to connect to a cell of a first radio-access technology, RAT, and to a cell of a second RAT. The method includes receiving location information for the wireless device, wherein the wireless device is connected to a first RAT cell hosted by the serving radio access node, and is also connected to a second RAT cell, and wherein a signal strength of the second RAT cell, received at the wireless device, has fallen below a trigger threshold. The method further includes identifying neighbour first and second RAT cells, and assembling, a candidate set of cell combinations.

Abstract: A method, performed by a first node (111) serving a wireless device (130) in a secondary cell group (122), to handle a change of the device (130) from a first cell (123) to a second cell (124). The first node (111) determines (609) whether to proceed or to suspend the change, with the proviso that a probability of RLF at the first cell (123) is under a threshold. The determining (609) is based on whether or not a predicted quality of communication between the wireless device (130) and the second cell (124) exceeds another threshold. The first node (111) sends (610) an indication to a second node (112) indicating to proceed with the change, wherein the first node (111): i) if the result is to proceed with the change, sends the indication, and ii) if the result is to suspend the change, refrains from sending (610) the indication and suspends the change.

Abstract: A computer-implemented method for adaptive beam management for load balancing communication devices over ports used for a channel state information reference signal, CSI-RS, in a telecommunications network. The method includes predicting from a machine learning model predicted channel quality indicator, CQI, values for target beam candidates for offloading one or more communication devices. The method includes identifying a target beam candidate having a highest CQI value from the predicted CQI values. The method includes deciding to offload the one or more communication devices from an offload beam candidate to the target beam candidate when a difference between the highest CQI value of the target beam candidate and a CQI value of the offload beam candidate is greater than or equal to a threshold value. The method includes initiating offloading of the one or more communication devices from the offload beam candidate to the target beam candidate.

Abstract: A method performed by a random access channel planning node. The random access channel planning node may identify a coverage overlap area of a candidate cell with each of the neighboring cells of the candidate cell in a radio access network. The random access channel planning node may use the identified coverage overlap area to determine a root sequence index for the candidate cell having a minimum root sequence index collision factor. The random access channel planning node may initiate a command to the candidate cell to set the root sequence index for the candidate cell to the determined root sequence index having the minimum root sequence index collision factor.

Abstract: Embodiments of the invention include methods, system, and software for physical layer sub-cell identity allocation to select a sub-cell identity vector for a network device in a wireless network. In one embodiment, a method includes selecting a plurality of sub-cell identity vector candidates for the network device from a set of possible sub-cell identity vector candidates, where the selecting removes one or more possible sub-cell identity vector candidates containing a same sub-cell identity for two or more adjacent sectors of the network device. The method further includes determining a plurality of conflict measurements for each of the plurality of sub-cell identity vector candidates. The method continues with deriving a single value from the plurality of conflict measurements for each of the plurality of sub-cell identity vector candidates and selecting the sub-cell identity vector for the network device from the plurality of sub-cell identity vector candidates based on the single value.

The first information comprises a session identifier (ID) and a first time stamp associated with the communication session. The method also comprises extracting second information about the communication session from a second log associated with the second RAT by filtering information relating to communication sessions which have moved between RATs from other communication sessions in the second log.

Abstract: A management node and method at the management node provide automatic PCI allocation to sites in a RAN by iteratively identifying a selected cell site to be allocated a PCI group. From a group of cell sites in the RAN that have already been allocated a PCI group, the method obtains, for each PCI group, a closest neighbor site having a least distance from the selected cell site. The method allocates a PCI associated with a closest neighbor site based on whether any of the closest neighbor sites meet criteria including, with respect to the selected cell site, a respective distance greater than a cluster distance, a lack of coverage overlap between any respective sectors, a tier relationship that is two or greater and a respective distance greater than an average cell footprint, and a lack of sectors that face any sectors of the given cell site.
