Multi-Carrier Base Station Tethering via Wired Backhaul
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless access technologies face challenges in seamlessly managing home WiFi networks and 3GPP networks, particularly due to capacity constraints and interference issues, especially when trying to tether non-3GPP radio access over 3GPP networks in residential environments.
Innovation Solution
A multi-carrier base station (MCBS) is introduced, integrating a base transceiver station (BTS) with a tethering access point (AP), where the BTS provides a first carrier for 3GPP access and a second carrier exclusively for the tethering AP via a wired connection, allowing the AP to act as a non-3GPP access point, thereby enabling transparent WiFi backhauling without air interface interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a UE acts as a tethering access point to connect non-3GPP devices to the 3GPP network, then wireless access is enabled for non-3GPP terminals, but air interface capacity is consumed and interference from adjacent cells occurs
Solution Approach 1:
The patent segments the network into two distinct parts: a wired backhaul connection for the tethering access point and a wireless air interface for regular 3GPP users. This segmentation allows the tethering AP to use dedicated wired resources rather than competing for air interface capacity, resolving the contradiction between enabling wireless access and preserving air interface resources.
Solution Approach 2:
The tethering access point acts as an intermediary device that bridges non-3GPP terminals to the 3GPP core network through a wired connection. This intermediary approach allows non-3GPP devices to access the network without directly consuming air interface capacity, as the tethering AP handles the wireless connectivity while using wired backhaul for data transmission.
2Productivity
If multiple carriers are provided to multiple users via air interface, then network capacity is increased, but interference management and resource allocation complexity increases
Solution Approach 1:
The patent segments the carrier resources by providing dedicated carriers through wired connections to tethering access points, separate from the air interface carriers used by mobile terminals. This segmentation increases network capacity by utilizing additional wired carriers while reducing resource allocation complexity at the air interface, as the wired carriers are exclusively assigned to specific tethering APs.
