This architecture allows for real-time processing and delivery of application services, optimizing communication performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If application instances are stored on cloud servers, then service coverage is improved, but transmission delay increases
Solution Approach 1:
The patent segments the centralized cloud server into multiple distributed MEC servers deployed at network edges. Each MEC server stores and manages application instances locally, enabling terminal devices to access services from the nearest edge server. This segmentation reduces transmission distance and delay while maintaining comprehensive service coverage through the distributed architecture.
Solution Approach 2:
The patent introduces a spatial dimension to service delivery by deploying MEC servers across multiple network edge locations rather than relying on a single centralized cloud server. This multi-dimensional deployment allows terminal devices to access services from geographically distributed edge servers, reducing transmission delay while expanding overall service coverage.
2Productivity
If common application instances are maintained on cloud servers, then resource utilization is improved, but adaptability to personalized services deteriorates
Solution Approach 1:
The patent enables each MEC server to have local quality characteristics by allowing different MEC servers to store different sets of application instances based on local service demands. Terminal devices can access personalized services from their local MEC server, while the system maintains resource efficiency through selective caching of frequently accessed applications at each edge location.
Solution Approach 2:
The patent implements preliminary action by pre-storing application instances at MEC servers based on predicted service demands and access patterns. The MEC server proactively caches application instances that are likely to be requested by terminal devices in its service area, reducing access delay while maintaining resource efficiency through demand-driven pre-positioning of services.
3Loss of time
If MEC servers prestores application instances, then transmission delay is reduced, but device complexity increases
Solution Approach 1:
The patent applies universality by designing MEC servers with multi-functional capabilities that can handle multiple application instances and service types within a single platform. The MEC server architecture provides universal service delivery mechanisms that work across different application scenarios, reducing the need for specialized hardware or software for each specific service while maintaining low transmission delay.

AI summary
Embodiments of this application relate to the field of communication technologies, and disclose a communication method and a MEC server. The communication method is applied to the MEC server, and the MEC server prestores an application instance. The method includes: The MEC server receives a service request from a terminal device, where the service request corresponds to a first application instance; and after finding the first application instance from prestored application instances, the MEC server invokes the first application instance to provide an application service for the terminal device. The MEC server is deployed on a network edge, and therefore the application instance and the like are deployed on the network edge. As a result, when the terminal device accesses the application instance in the MEC server, a transmission path of data such as the application instance can be shortened, to reduce a transmission delay and improve communication performance.
