Embodiments of the present disclosure provide a resource allocation method and apparatus for a small cell cluster and a communications system. The resource allocation method includes: exchanging by the base station of the upper level with another base station of the upper level, to obtain information on resources and/or interference of the other base station of the upper level; receiving information by the base station of the upper level at least from the cluster head of the SCC, to obtain information on resources and/or interference of the base station of the upper level; and allocating resources for the small cell cluster by the base station of the upper level based on the obtained information on resources and/or interference of the other base station of the upper level and the information on resources and/or interference of the base station of the upper level. According to the embodiments, interference coordination may be performed efficiently on a small cell cluster at an edge of the base station of the higher lever, so as to lower the interference to the small cell cluster, and the expandability of the network may be improved.

A network node in a telecommunications network stores information defining at least one network slice. For at least one defined network slice, information is stored identifying a plurality of cells that define at least a part of a boundary of a coverage area of the network slice. The operation of a cell is then adapted depending on whether or not the cell defines at least a part of the boundary of the coverage area of the network slice.

The present application relates to the field of communications technologies, and provides an inter-small cell handover method, a device, and a system. When UE is in a coverage hole of a serving small cell, the UE needs to perform synchronous measurement only on each available beam pair in a set of available small cells determined by the UE, thereby reducing a delay of re-accessing a high frequency network by the UE, and improving QoS of receiving a high frequency service by the UE. the present application includes: performing, by UE, synchronous measurement, to determine a set of small cells available for the UE; sending the set of available small cells to a macro base station; when the UE is in a coverage hole of a current serving small cell, receiving, by the UE, a first synchronization indication sent by the macro base station.

According to certain embodiments, a method by a network node (860) for shifting cell borders of multiple frequency bands includes deploying at least two frequency bands. Each of the at least two frequency bands have at least two cells, and each cell have an associated cell coverage area within a common target coverage area. Each of the at least two frequency bands are associated with a respective interference area along a respective cell border, and each interference area is characterized by interference from an adjacent cell. The associated cell coverage area of at least one of the at least two frequency bands is adjusted such that the respective cell border of the at least one of the at least two frequency bands is shifted to reduce a common interference area of the at least two frequency bands. The common interference area is an area where the respective cell borders of the at least two frequency bands overlap.

Systems and methods are disclosed for managing network elements in a telecommunications network. In an embodiment, a real-time processing module processes stream data representing one or more network elements in the telecommunications network to build a real-time view. The real-time processing module stores the real-time view in a view database. A batch processing module processes snapshot data representing all the network elements in the telecommunications network to build a batch view. The batch processing module processes the snapshot data slower than the real-time processing module processes the stream data. The batch processing module saves the batch view in the view database. A presentation module presents a selected view from the view database for display.

In two-dimensional map data showing buildings to be candidates in which terminal station devices are to be installed, a position of a base station installation structure to be a candidate in which a base station device is to be installed is set as a base station candidate position, an unobstructed view for each of the buildings from the base station candidate position is determined based on the map data while excluding a region blocked by the building having an unobstructed view from the base station candidate position, and a range of a contour line having an unobstructed view of the building determined as having the unobstructed view is detected as an unobstructed view range. A candidate of, among wall surfaces of the building corresponding to the detected unobstructed view range, the wall surface on which the terminal station device can be installed is extracted. Three-dimensional point group data obtained by taking an image of a region including the base station installation structure and the building is narrowed down using information concerning the extracted wall surface. An unobstructed view for the building from the base station candidate position is determined using the narrowed-down point group data.
