Engineering Contradiction Analysis
1Loss of time
If computational services are provided at radio base stations to reduce latency, then response time is improved, but resource utilization becomes too high and congestion occurs
Solution Approach 1:
The patent implements dynamic migration of computational services between radio base stations and core network nodes based on real-time resource utilization conditions. When resource utilization at a radio base station exceeds a threshold, the computational service is migrated to another location, allowing the system to adapt dynamically to changing load conditions while maintaining low latency performance
2Productivity
If computational services are migrated to core network nodes to reduce resource utilization at base stations, then resource allocation is improved, but latency increases
Solution Approach 1:
The patent applies local quality by placing computational services at radio base stations (edge computing) when possible to serve local users with low latency, and only migrating to core network nodes when absolutely necessary. This localized approach ensures that most computational operations remain close to the users, maintaining low latency while allowing resource migration when needed
3Speed
If radio base stations are equipped with computational hardware to execute services locally, then execution speed is improved, but device complexity increases
Solution Approach 1:
The patent makes radio base stations universal by enabling them to function both as traditional communication infrastructure and as computational service execution environments. The base stations can dynamically host computational services when needed, eliminating the need for separate dedicated computing infrastructure while maintaining execution speed advantages

AI summary
Mechanisms for migration of a stateless computation service in a mobile communication network. A method, performed by a control node comprises obtaining, from a core network node in the mobile communication network, information indicative of a need to migrate the stateless computation service from a source compute node in the mobile communication network. The need results from resource utilization at the source compute node is too high, and/or a demand from user equipment for the stateless computation service elsewhere in the mobile communication network. The method comprises initiating migration of the stateless computation service from the source compute node to a target compute node in the mobile communication network for hosting of the stateless computation service at the target compute node.
