A radio controller entity is in communication with a centralized control plane entity of a disaggregated base station, or with a monolithic base station, the disaggregated base station or monolithic base station serving wireless user equipment in a wireless network. The radio controller entity obtains from the centralized control plane entity or from the monolithic base station, a context associated with one or more user equipment served by the disaggregated base station or the monolithic base station. The radio controller entity determines a policy to be set. The policy defines a set of one or more rules, each rule including a condition and an action. The rule may include that the base station should query the radio controller for an instruction as to which action(s) to apply. The radio controller entity provides the policy to the centralized control plane entity or to the monolithic base station.

Procedures for interaction between the radio controller and the subordinated base station

Systems and methods are provided by which a radio controller, also called a radio intelligence controller (RIC), is configured as a platform that hosts one or more third party applications. The radio controller platform provides the applications with access to radio access network (RAN) information and a command interface. An application programming interface is defined between the applications and the radio controller. The radio controller collects information from the RAN node and makes that information available to the applications. The applications also provide input information to the radio controller, such as in the form of a commands or a radio controller policy. The radio controller policy rules from the applications are executed by the radio controller or direct the radio controller to query one of the applications for an instruction.

Interaction between radio controller platform and third party applications

A method for cross-domain service optimization is implemented on a computing device and includes defining at least one key quality indicator (KQI) target for at least one end-to-end (E2E) service, where the at least one E2E service crosses more than one domain of a communications network, receiving an indication of quality of experience (QoE) for the at least one E2E service, based on the indication of QoE, translating the at least one KQI target to at least one set of service optimization instructions for each domain from among the more than one domain, and for each domain, applying the service optimization instructions.

Cross-domain service optimization

In one embodiment, a mobile base station includes: an antenna; a transceiver operative to communicate with a user equipment (UE) via said antenna; a processor; and a mobility control application to be executed by said processor and operative: to provide to said UE when in communication with said mobile base station at least a relevant tracking area list from among at least two tracking area lists associated with said mobile base station.

One example method is provided for dynamic allocation of air interface resources in a cellular network comprising at least three wireless cells located within a geographical proximity of each other, the method comprising determining, by a central managing entity, one or more classification rules for classifying each of said plurality of mobile devices according to the one or more classification rules; providing, by the central management entity, to a group of base stations associated with the at least three cells, information that comprises: information that relates to the determined one or more classification rules; information that relates to semi-static allocation of blocks of air interface resources adapted for use by one or more specific members of the group of base stations.

Method and system for dynamic allocation of resources in a cellular network

In one embodiment, a method for optimizing tracking areas for user equipments (UEs) is implemented in a mobile network and includes: defining network slices as a function of UE types, where UEs in the mobile network are associated with the network slices according to the UE types, defining network slice specific tracking areas as groups of one or more mobile base stations according to the network slices; receiving a signal from a given UE from among the UEs at a receiving mobile base station from among the one or more mobile base stations, and paging the given UE in a network slice specific tracking area from among the network slice specific tracking areas, where the receiving mobile base station is in the network slice specific tracking area, and the given UE is associated with the network slice specific tracking area according to an associated UE type from among the UE types.

One example method is provided for dynamic allocation of air interface resources in a cellular network. The method can include at least three wireless cells located within a geographical proximity of each other. The method can include determining, by a central managing entity, one or more classification rules for classifying each of said plurality of mobile devices according to the one or more classification rules. The method can also include providing, by the central management entity, to a group of base stations associated with the at least three cells, information that can include, at least in part, information that relates to the determined one or more classification rules and information that relates to semi-static allocation of blocks of air interface resources for use by one or more specific members of the group of base stations.

A way of optimizing communication by minimizing the momentary overall radiated energy under constraints in respect to coverage and maintenance of communication with the users, is provided herein. Channel parameters are estimated from downlink and/or uplink communications or from user equipment messages and desirable gain factors are derived from the minimization.
