Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current technologies fail to enable Local Area Network (LAN) communication over wireless networks, limiting mobile terminals to fixed wired modes and increasing deployment costs.
Innovation Solution
A communications device with a Mobile Local Access Network (MLAN) controller, authentication and authorization module, and forwarding processing module, integrated with the Mobile Edge Computing (MEC) module, facilitates LAN communication by establishing tunnels between mobile terminals and base stations using tunneling protocols like GRE, reducing costs and enabling wireless LAN establishment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fixed wired mode is used for LAN deployment, then network stability is improved, but mobility and adaptability are worsened
Solution Approach 1:
The patent replaces the mechanical wired connection system with a wireless communication system. Mobile terminals establish LAN connections through wireless networks instead of physical cables, substituting the mechanical plug-and-play approach with radio frequency communication while maintaining network functionality
Solution Approach 2:
The patent introduces a network side device as an intermediary that establishes tunnels between mobile terminals and the network. This intermediary enables wireless LAN functionality by mediating the connection between mobile devices and the core network, allowing LAN services over wireless infrastructure
2Ease of operation
If wireless network is used for mobile terminal communication, then mobility and ease of operation are improved, but LAN establishment capability is worsened
Solution Approach 1:
The patent implements dynamic LAN establishment where the network side device dynamically creates and manages tunnels for mobile terminals as they move between base stations. The LAN configuration adapts to the terminal's movement state, maintaining connectivity without requiring manual reconfiguration
Solution Approach 2:
The patent enables mobile terminals to simultaneously perform wireless communication and LAN participation through the network side device. The same wireless infrastructure serves both mobile connectivity and LAN functionality, making the system multi-functional without requiring separate wired connections
3Adaptability or versatility
If multiple MLAN networks are established, then adaptability and coverage are improved, but device complexity and management difficulty are worsened
Solution Approach 1:
The patent segments the network management function by separating the control plane (network side device managing tunnel configurations) from the data plane (mobile terminals communicating through tunnels). Each MLAN network is independently managed through dedicated tunnels, allowing multiple networks to coexist without interference while simplifying individual network management

AI summary
Embodiments provide a communication method, including: receiving data that is sent by a terminal through a base station, where the data includes an identifier of a receive end and to-be-sent information, the receive end and the terminal are located in a mobile local access network MLAN, and the MLAN is a local access network established based on a wireless cellular network; and sending, based on an MLAN address corresponding to the identifier of the receive end, the to-be-sent information to the receive end through the base station. It can be learned that a wireless network-based LAN can implement data communication between the terminal and the receive end without depending on a wired mode, and therefore costs can be reduced.
