Aspects of the subject disclosure may include, for example, identifying a set of network functions operative on a core network of a mobile communications system instantiated on a cloud network, identifying functional dependencies among respective network functions of the set of network functions, defining a sequence by which the set of network functions should be made unavailable prior to a maintenance event, wherein the defining the sequence is based on the functional dependencies, and deactivating respective network functions of the set of network functions according to the sequence. Other embodiments are disclosed.

Traffic steering for non-public networks and public land mobile network (PLMN) clouds is provided. A method can include retrieving, by a system comprising a processor and associated with a communication network, a subscriber profile for a user equipment in response to receiving a request from the user equipment for access to the communication network, wherein the request comprises first data network information that is distinct from second data network information associated with the communication network; and, in response to an attribute of the subscriber profile being determined to be equal to a defined value, replacing, by the system, the first data network information in the request with the second data network information and routing, by the system, the request to core network equipment of the communication network.

Processes, computing systems, devices, and automated processes variously perform or include operations to update a cellular device running a container-based operating system. A container management server (CMS) of a cellular network receives a communication from the cellular device over the cellular network. The CMS retrieves a list of containers deployed on the cellular device. The CMS then compares a deployed container from the list to an updated container to identify the deployed container as invalid. The CMS may push the updated container to the cellular device in response to identifying the deployed container as invalid.

Aspects of the subject disclosure may include, for example, obtaining, by a processing system including a processor, network data associated with a communication network; generating, by the processing system, Quality of Service (QoS) information by applying machine learning to the network data; and providing, by the processing system, the QoS information to a Policy Control Function (PCF) that selects or generates a first UE Route Selection Policy (URSP) rule according to the QoS information and provides the first URSP to an end user device, where the first URSP rule is implemented to provide a communication service to the end user device utilizing an application via the communication network. Other embodiments are disclosed.

A bearer creation system creates dedicated bearers for sessions requested by user equipment devices based on a policy associated with the user equipment device. The bearer creation system detects that a request to initiate a session has been sent by user equipment associated with a policy. The bearer creation system compares the request to initiate the session to information indicated by the policy, and determines whether to create a dedicated bearer for the session based on the comparison. The bearer creation system creates a dedicated bearer for the session based on a determination that a dedicated bearer should be created.

Systems and methods to automatically create dedicated bearers during failure event

According to the present disclosure various network functions are dynamically instantiated on a selected data center to utilize the most efficient and rapid resources available. An analytic module and a data lake receive performance data from the various data centers of a cellular network, such as a Regional Data Center, a National Data Center and an Edge Data Center. The analytic module will analyze the received performance data and apply artificial intelligence and machine learning to determine current resource use and estimate future resources available on various data centers of the cellular network. The appropriate data center is then selected to perform a particular network function.

Systems, devices and methods for customer specific network slicing include a virtual network operator (VNO) server, a first node, and a virtualized network. The VNO server instantiates a solution manager engine which identifies a Solution, communicates the Solution to the first node, and upon acceptance of the Solution by the first node, instructs the virtualized network to couple the first node with a second node in accordance with the Solution. The virtualized network may include network function virtualization infrastructure and the Solution may include a slice of the virtualized network. The slice satisfies a Service Level Requirement (SLR), such as one that specifies a maximum latency for the slice. The SLR is specified in a Need received by the VNO server from the first node. The SLR is determined based upon an application program the first Node is at least one of currently executing and expected to later execute.

Customer specific network slicing

A session change over system monitors nodes to determine whether they are operational, and transfers user equipment from one node to another when nodes are not operational. The session change over system receives one or more health check messages from one or more foreign nodes which communicate with user equipment. The session change over system inspects each health check message to determine whether a foreign node is not operational. The session change over system identifies user equipment in communication with the foreign node at a time before the foreign node was not operational. The session change over system communicates with the identified user equipment in place of the foreign node.

A facility for conveying first side of a voice call from a first participant to a second participant is described. Over the duration of the voice call, the facility receives the first side of the call. The facility seeks to forward the received first side of the voice call to a downstream node on a path to the second participant. The facility records the received first side of the call for at least part of the call. The facility identifies a just-ended portion of the voice call for which forwarding of the received first side of the voice call was unsuccessful. In response, the facility transmits to the downstream node the recorded first side of the voice call that coincides with the identified portion of the voice call.

Techniques are described for end-to-end overwatch of communication sessions in a network for fast failure recovery. At any time, network functions (NFs) can be supporting end-to-end connectivity for large numbers of concurrent active communication sessions. Conventionally, if one or more of the NFs fail, session context information can be irretrievably lost, and session connectivity is lost. Embodiments provide an overwatch system in an overwatch plane of the network to determine critical session context dataset (CSCDs) for NFs participating in active communication sessions, and to continuously take snapshots of the entire end-to-end context of active communication sessions in accordance with the CSCDs and endpoint information for the NFs. In the event of a session failure, embodiments generate recovery data from the recorded end-to-end context data, which can be used to rapidly restore full, end-to-end session connectivity, thereby maintaining the active communication session without a loss of session context.
