LTE QoS Bearer Setup via Wireless Sharing Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
LTE networks often fail to provide quality of service (QoS) to user devices that are not directly connected, such as those accessing the network through a wireless sharing device, as they do not recognize the QoS-based service being requested via the sharing device, leading to inadequate bitrate and latency for services like VoLTE and video streaming.
Innovation Solution
Implementing a system where a network device, like the Call Session and Control Function (CSCF), receives identification information from the wireless sharing device to associate it with the user device, establishing a bearer that defines network policy rules to ensure the QoS requirements are met, allowing the LTE network to provide the QoS-based service through the wireless sharing device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If user devices connect to LTE network via wireless sharing device, then network access is enabled, but QoS requirements (bitrate, latency) are not met
Solution Approach 1:
The patent introduces an intermediary mechanism (bearer establishment with QoS parameters) between the user device and the LTE network. The network device acts as a mediator that receives QoS requests from the wireless sharing device, establishes appropriate bearers with specific QoS parameters (bitrate, latency), and ensures these parameters are enforced throughout the network path, thereby resolving the contradiction between enabling network access and maintaining service quality.
2Reliability
If LTE network recognizes QoS-based service requests, then appropriate QoS is provided, but network complexity increases
Solution Approach 1:
The patent implements a universal bearer establishment mechanism that can handle multiple QoS requirements through a standardized process. The same bearer setup procedure and QoS parameter enforcement mechanism apply regardless of the specific service type (video streaming, VoLTE, etc.), allowing the network to provide differentiated QoS without proportionally increasing complexity for each service scenario.

AI summary
A device associated with a cellular network may receive a request for a quality-of-service based service from a wireless sharing device that is in communication with a user device. The user device may connect with the cellular network via the wireless sharing device. The request may include identification information. The identification information may include a user device identifier and a wireless sharing device identifier. The quality-of-service based service may be provided based on an identified quality-of-service level. The device may establish a bearer based on the request. The bearer may be used by one or more network devices to provide the quality-of-based service, with the quality-of-service level and via the wireless sharing device, to the user device.
