Solution Overview
Problem
Current 5G wireless communication systems face challenges in accommodating the increasing number of terminal devices and network data usage, particularly in supporting virtual reality, augmented reality, and the Internet of Things, requiring enhanced network capacity and flexibility.
Innovation Solution
The implementation of a network access method and apparatus that utilizes relay nodes (RNs) to expand signal coverage and increase network capacity, allowing for multi-hop RN deployments and wireless self-backhauling, which reduces deployment costs and improves flexibility, especially in the initial stages of 5G and evolved communication systems.

Engineering Contradiction Analysis
1Productivity
If relay nodes are deployed to expand signal coverage and increase network capacity, then network capacity and coverage are improved, but network complexity and deployment challenges increase
Solution Approach 1:
The patent segments the network into multiple relay nodes that can independently operate and make local access control decisions. Each relay node is divided into functional modules (receiver, processor, transmitter) that handle specific tasks, allowing the overall network to scale without proportionally increasing central control complexity.
Solution Approach 2:
The patent implements local quality by enabling each relay node to make autonomous access control decisions based on local conditions (signal quality, load status, hop count). This distributed intelligence reduces the need for centralized control mechanisms, managing network complexity while maintaining high network capacity.
2Area of stationary object
If multi-hop relay node deployments are implemented, then signal coverage area is expanded, but access control and network management difficulty increase
Solution Approach 1:
The patent applies preliminary action by pre-configuring each relay node with access control parameters (maximum hop count, allowed site types, load thresholds) before deployment. This allows relay nodes to autonomously enforce access control policies without real-time centralized intervention, simplifying management of multi-hop networks while expanding coverage.
Solution Approach 2:
The patent implements feedback mechanisms where relay nodes continuously monitor network conditions (signal quality, load status, hop count) and adjust access decisions accordingly. This automated feedback loop simplifies access control in multi-hop scenarios by eliminating manual intervention while maintaining optimal coverage.
3Ease of manufacture
If wireless self-backhauling is used in relay nodes, then deployment flexibility and cost are improved, but network overload and congestion may occur
Solution Approach 1:
The patent applies dynamics by making relay nodes dynamically adjust their backhaul usage based on real-time network conditions. Relay nodes monitor load status and signal quality, dynamically selecting whether to use wireless self-backhauling or traditional wired backhaul, thereby maintaining deployment flexibility while preventing network overload through adaptive resource allocation.

AI summary
A network access method includes: learning, by a first RN, that a site type of a first communications site is an RN; and sending, by the first RN, first indication information to the first communications site, so that the first RN accesses the first communications site, where the first indication information carries information indicating that a site type of the first RN is an RN.
