Abstract: Embodiments of the present invention relate to an RRC connection method and a serving node. In the embodiments, an RRC connection is established between an anchor node and UE. Therefore, when an serving node of the UE is switched, a connection between an MME and the anchor node does not change. When the MME needs to send a paging message, the MME does not need to send the paging message to all base stations in a TA area that corresponds to the paging message, thereby effectively reducing signaling load of a core network.

Abstract: Data usage by networking and data processing services is measured using a timeslot system. The timeslots have multiple states for collecting, collecting with processing, and expired timeslots. Data from upstream components is reported to local manager clusters and placed into timeslots corresponding to a timestamp of the data. Data can be reported from local managers to an entitlement service and/or a cloud service portal. Timing inconsistencies due to latency or processing time can be resolved by accounting for a timestamp difference using a timestamp difference value between the timeslot time and the reporting time. Data can be deduplicated, cleaned, and/or compacted. Data can be also be version controlled, with timeslots maintaining a version number. Complete and accurate tracking of data usage and associated costs is improved by reporting and collecting usage data using state-based timeslots.
