Offload Base Station Resource Configuration for Wireless Service Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In LTE networks, primary base stations face increased pressure due to growing user services, leading to low utilization of network resources as other serving base stations do not establish radio bearers and thus cannot utilize their resources effectively.
Innovation Solution
A method where a first base station sends a request message to an offload base station with service information, including QoS and RB configuration, and sends a configuration message to the UE, allowing the offload base station to configure resources and the UE to configure its RB accordingly, thereby enabling the offload base station to handle service transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple serving base stations serve each user terminal, then service capacity and user data rate are improved, but network resource utilization deteriorates because only the primary base station establishes radio bearers while other base stations only forward services at physical layer
Solution Approach 1:
The patent segments the service transmission function across multiple base stations by introducing secondary base stations that independently establish radio bearers for specific services. This divides the traditional single-primary base station model into multiple independent service delivery paths, allowing each base station to manage its own resources and services without relying solely on the primary base station for bearer establishment.
Solution Approach 2:
The patent makes multiple base stations universal by enabling each serving base station to perform both service forwarding and independent radio bearer establishment. The secondary base stations are equipped with full functionality including RRC connection management and radio bearer configuration, transforming them from simple forwarding nodes to multi-functional base stations capable of independent service delivery.
2Productivity
If services of user terminal grow fast, then user data rate is improved, but pressure on primary base station increases resulting in low utilization of network resources
Solution Approach 1:
The patent segments the service transmission load by introducing secondary base stations that handle specific services independently. This divides the burden of service delivery from the primary base station, allowing services to be distributed across multiple base stations rather than concentrating all traffic through a single primary node.
Solution Approach 2:
The patent introduces secondary base stations as intermediary nodes between the user terminal and the network core. These intermediary base stations receive services from the primary base station and forward them to the user terminal through independent radio bearers, acting as buffers that reduce direct pressure on the primary base station while maintaining service delivery.
3Device complexity
If other serving base stations only forward services at physical layer, then device complexity is reduced, but network resource utilization deteriorates because resources of other base stations cannot be utilized properly
Solution Approach 1:
The patent introduces dynamic capability to secondary base stations by enabling them to establish and manage radio bearers on-demand based on service requirements. Rather than being static forwarding nodes, the secondary base stations can dynamically configure their resources according to actual service traffic patterns, optimizing resource utilization while maintaining operational flexibility.
Solution Approach 2:
The patent changes the operational parameters of secondary base stations by transitioning them from fixed physical-layer forwarding mode to a mode where they can dynamically establish radio bearers and manage resources based on service QoS requirements. This parameter change enables resource optimization while adapting to varying service demands.
Data Source
AI summary
A service transmission method is provided. A first base station, which establishes an RRC connection with a UE, sends a request message to a second base station which is at least one of base stations serving the UE, where the request message includes service information, where the service information includes QoS information of a service and/or configuration information of an RB, and the request message instructs the second base station to perform resource configuration according to service information. The first base station sends a configuration message to the UE, where the configuration message includes configuration list information of the RB and/or cell information of the offload base station.
