A search range decision unit (103) first decides, as a narrow-down count, the number of transmission points for which each of user wireless terminals becomes a connection candidate, based on the number of user wireless terminals that perform wireless communication with one of the plurality of transmission points. In addition, the search range decision unit (103) limits, based on combination conditions stored in a storage unit (102), the number of the plurality of transmission points that can be combined with one of the user wireless terminals according to the narrow-down count, and sets combination limitation information that associates the plurality of transmission points with the user wireless terminals that are the connection candidates for each of the plurality of transmission points.

The techniques described herein relate to methods, apparatus, and computer readable media configured to provide a distributed core framework for a voice and data network. A control plane comprising a set of control plane components is executed using a set of virtual machines running on a set of computing devices. The control plane comprises a first network interface to the voice and data network that is shared by the set of control plane components. A data plane comprising a set of data plane components is executed using a set of virtual machines running on a set of computing devices. The data plane comprises a second network interface to the voice and data network that is shared by the set of data plane components. Upon receipt of a session request from a remote device, a selected data plane component is selected to handle a corresponding session, such that the selected data plane component can directly communicate with the remote device using the second network interface to handle the session.

A system for managing a network comprising an Operator Domain. The system comprises a hierarchical system of management functions; and a respective service catalogue associated with each management function. The service catalogue storing information of services that can be provided by the management function to at least one higher level management function.

An operation method of a first device in a communication system supporting network slicing may comprise receiving a first message requesting capacity planning of a network slice from a second device; obtaining information required for the capacity planning; transmitting a second message including the required information to a third device supporting a function of the capacity planning; receiving a third message including a result of performing the capacity planning from the third device; and performing a reallocation operation or a modification operation of the network slice based on the result of performing the capacity planning.

Systems and methods of performance management over a life cycle is provided. A measurement job control service producer receives, from an authorized consumer, a request to consume a measurement job control service. The request is analyzed, appropriate action is taken to satisfy the request and a response indicating the request result is generated. A request is to create or terminate a measurement job to collect the performance data for a NF, NSSI, NSI, or network. To create a job, the producer checks if the job can be supported by an existing job, creates the job if no such existing job exists, and otherwise responds that the job can be supported by the existing job. To terminate a job, the producer checks if the job is serving other consumers, terminates the job if other consumers are not being served, and otherwise responds that the job is currently serving other consumers.

Systems and methods provide automated generation of neighbor frequency lists for configuration of frequency objects for wireless stations. A computing device selects a target sector carrier of a wireless station of multiple wireless stations in a radio access network and identifies, based on distances from the wireless station, neighboring sector carriers of the target sector carrier. The computing device filters the neighboring sector carriers based on an azimuth of the target sector carrier to form a filtered set of neighboring sector carriers. The computing device calculates a probability of neighboring frequencies for the target sector carrier based on locations of the filtered set of neighboring sector carriers and generates, based on the calculating, a neighbor frequency list for the target sector carrier. The neighbor frequency list is used to configure frequency objects, for the target sector carrier, that ensure seamless handovers within the radio access network.
