Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple mobility management protocols are integrated into a single communication network, then network access versatility is improved, but signalling requirements and processing power needs increase
Solution Approach 1:
The patent segments the mobility management functionality by introducing separate mobility management entities (MMEs) for different protocols (e.g., GSM MME, UMTS MME, LTE MME). Each MME handles only its specific protocol, avoiding the need for a single entity to process all protocols simultaneously. This segmentation reduces the signalling complexity and processing burden on individual network elements while maintaining multi-protocol support across the network.
Solution Approach 2:
The patent introduces a gateway or interface mechanism that acts as an intermediary between different mobility management protocol domains. This intermediary enables coordinated handling of mobile terminals using multiple protocols without requiring each protocol handler to directly process all other protocols, thereby reducing overall signalling requirements while maintaining protocol interoperability.
2Adaptability or versatility
If multiple mobility management protocols are handled simultaneously, then protocol versatility is improved, but processing power requirements increase
Solution Approach 1:
The patent divides the processing workload by creating specialized mobility management entities for each protocol type. Each entity is optimized to handle only its specific protocol, which reduces the processing power required per entity compared to a general-purpose entity that must handle all protocols. The network can activate only the necessary protocol handlers based on current mobile terminal requirements, further optimizing power utilization.
Solution Approach 2:
While maintaining protocol-specific optimization, the patent enables mobility management entities to serve multiple functions within their protocol domain and allows the network as a whole to provide universal multi-protocol support. This multi-functionality at the network level, achieved through coordinated specialized entities, provides protocol versatility without requiring each individual entity to consume excessive processing power for all protocol types.
3Reliability
If dedicated mobility anchors are deployed for each protocol, then protocol-specific handling is improved, but network complexity increases
Solution Approach 1:
The patent implements protocol-specific mobility anchors (e.g., GGSN for GPRS, HA for MIPv6, PGW for LTE) segmented by protocol type. Each anchor is dedicated to handling its specific protocol's data packets, ensuring reliable protocol-specific processing. The network manages this complexity through standardized interfaces and coordination mechanisms that abstract the underlying multi-protocol complexity from end users and simplify network operations.
