User Equipment Charging Trigger for ProSe Services
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current technologies lack a detailed solution for charging ProSe (Proximity based Services) in wireless communication networks, especially when mobile devices are outside network coverage and cannot transmit charging related information directly to the network.
Innovation Solution
A method and system where user equipment generates and transmits charging requests for ProSe services, even when not connected to the wireless communication network, using a UE-CTF (User Equipment Charging Trigger) to obtain and process charging information and send requests to the charging system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If user equipment uses ProSe for direct device-to-device communication without network coverage, then communication quality and network offloading are improved, but charging capability is lost
Solution Approach 1:
The charging trigger function is established in advance within the user equipment, enabling the device to generate charging requests locally before network connection is available. This preliminary setup allows charging information to be captured and processed even when the device operates outside network coverage, resolving the contradiction between maintaining communication quality without network dependency and preserving charging capability.
Solution Approach 2:
The user equipment itself acts as an intermediary by hosting a charging trigger function that captures charging events locally. This intermediary mechanism bridges the gap between ProSe communication operations and network-based charging systems, allowing charging information to be generated and transmitted when network connection is available, while maintaining charging capability even during periods without network coverage.
2Device complexity
If charging request generation is centralized in the network, then charging control is simplified, but charging cannot be performed when user equipment is outside network coverage
Solution Approach 1:
The charging system is segmented by distributing the charging trigger function from the network to the user equipment. This segmentation allows the charging request generation to occur locally at the device level, enabling charging operations both inside and outside network coverage areas, thereby expanding charging versatility while maintaining manageable system complexity through standardized interfaces.
Solution Approach 2:
The user equipment is endowed with multi-functionality by integrating both ProSe communication capabilities and charging trigger functions. This universal design allows the same device to perform direct device-to-device communication while simultaneously generating and managing its own charging requests, regardless of network coverage status, thus achieving both simplified control and expanded charging coverage.
