The application is directed to a method for improving a user's experience on an electronic device. An application for modifying data service is displayed on a display of an electronic device. A request is received by the application from a user to modify a current data service with a new data service. The application evaluates the requested, new data service in view of predetermined information based upon the user. The application updates the electronic device with the new data service after its evaluation.

Methods, servers and systems for directly accessing and modifying charging information maintained within a telecommunications operator's business and operating systems' infrastructure from user equipment. A mobile application server may receive a charging request from a user equipment, identify a relevant charging system based on the received request, send a charging request to the identified charging system for processing, receive a first response message including charging information from the identified charging system, generate a second response message based on the charging information included in the first response message, and send the generated second response message to the user equipment. The received charging request may include various types of information, including information for transferring cost or billing information from a first billing category to a second billing category.

This application provides a network slice charging method and an apparatus. The method includes: A network slice management network element receives a first request including a charging requirement of a network slice. The network slice management network element sends to a network slice subnet management network element, a second request including the charging requirement. The network slice management network element receives first charging data of the network slice, which is collected based on the charging requirement. The network slice management network element sends the first charging data to a charging network element for the charging network element to charge the network slice.

Presented are methods and systems to universally assess composite utility consumption (1) in which a plurality of real-time and batch sensor readings such as from multiple disparate utility sensor data inputs (3) may be acquired and stored such as into a local device (2) or a central data warehouse (6). A composite utility estimated cost generator (9) can generate missing or uncorrelated data and a collected composite utility data information correlator (11) can correlate the data so it can be applied to determine some type of composite utility cost information. For real-time calculation, a disparate utility rate information accessor (8) can obtain multiple items of disparate rate information and this can use with correlated data to create a composite utility consumption and spend so a user can manage and control utility usage for a home, building, facility, plant, specific equipment, or the like. Cost information, such as a rate of spend or spend amount(s) to date or for a period may be presented to user in a variety of visualizations and reporting formats including specific time usage and spend information, specific time range usage and spend, and time-of-use billing information for specific real-time data points. The visualization and reporting may be used to answer a plurality of usage questions along with specific characterizations of utility spend across time of day domains and specific equipment usage domains thus affording more effective utility cost management.
