MEC Function Deployment Across RAN and Core Nodes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Mobile-Edge Computing (MEC) implementations in 3GPP mobile communication networks face challenges in efficiently deploying and managing MEC functions across different nodes in the Radio Access Network (RAN), RAN aggregating nodes, and core network nodes, limiting the effectiveness of information collection and local service caching and shunting.
Innovation Solution
The method involves deploying MEC functions on RAN nodes, RAN aggregating nodes, or core network nodes, allowing for information collection and local service shunting through various interfaces such as the air interface, S1 interface, and HLR/HSS, enabling flexible deployment and processing of MEC services by these nodes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If MEC functions are deployed on multiple nodes (RAN, RAN aggregating, core network nodes), then service flexibility and local processing capability are improved, but system complexity and management difficulty increase
Solution Approach 1:
The patent segments the MEC system into multiple deployment options across different network nodes (RAN nodes, RAN aggregating nodes, core network nodes). Each node can independently host MEC functions, allowing the system to be divided into manageable units that can be deployed flexibly based on service requirements without overwhelming complexity at any single point.
Solution Approach 2:
The patent creates a universal MEC deployment framework that can operate across multiple types of network nodes. The same MEC function can be deployed on different node types depending on service needs, making the system multi-functional and adaptable while using a consistent management approach across all nodes.
2Loss of time
If MEC functions are deployed at the network edge, then access delay is reduced and real-time processing is improved, but information collection capability and service management become more challenging
Solution Approach 1:
The patent introduces standardized interfaces as intermediaries between the distributed MEC functions and the network core. These interfaces (including air interface, S1 interface, and HLR/HSS) mediate information collection and service management, making it easier to gather information from edge-deployed MEC functions while maintaining real-time processing capabilities.
Solution Approach 2:
The patent establishes predetermined interface protocols and communication mechanisms before MEC functions are deployed at the edge. These preliminary actions define how information will be collected and managed, reducing the difficulty of information collection even as MEC functions are distributed across multiple edge nodes.
3Ease of manufacture
If standardized interfaces are used for MEC deployment, then interoperability and ease of deployment are improved, but flexibility in implementing custom MEC solutions is reduced
Solution Approach 1:
The patent designs standardized interfaces that serve multiple purposes: they provide a common deployment framework for ease of implementation while also supporting various custom MEC solutions. The same interface standards can accommodate both standardized services and customized applications, making the system both easy to deploy and flexible enough for custom solutions.
