Abstract: Systems, methods, and apparatus are disclosed that provide in-service traffic and/or resource migration between processing units in a communications network. An example method includes one or more processing units communicating with at least one processing unit of a plurality of processing units, where the communicating corresponds to a plurality of resources and resource requirements of the plurality of processing units. The one or more processing units evaluate resource utilization and projected traffic of a subset of the plurality of processing units. The one or more processing units determine, based on the resource requirements, to migrate one or more selected interdependent resources for a service from one or more processing units to one or more receiving processing units of the plurality of processing units.

Abstract: A method and a network node device for auditing a Visitor Location Register (VLR) to manage communication device retention. The method comprises, when the age of a communication device's age in the VLR reaches or exceeds a first threshold, triggering a request to a Mobility Management Entity (MME) to notify the VLR of the communication device's activity. The method further comprises receiving a notification from the MME indicating the communication device's activity, and updating the communication device's aging information based on the notification.
