Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the RNC performs admission control according to cell capability and cell resource in prior art, then the configuration is proper for single HSDPA serving cell, but the RNC cannot perform proper configuration for HSDPA multiflow transmission operation
Solution Approach 1:
The cell capability information is segmented into multiple types: basic cell capability information and multiflow transmission capability information. The base station separately reports these different types of capability information to the RNC, allowing the RNC to properly configure HSDPA multiflow transmission operations while maintaining compatibility with existing single-cell configurations.
Solution Approach 2:
The base station performs preliminary action by obtaining and reporting multiflow transmission capability information to the RNC before the RNC needs to configure HSDPA multiflow transmission operations. This ensures that the RNC has the necessary capability information available when configuration decisions need to be made, enabling proper admission control and resource allocation for multiflow scenarios.
2Adaptability or versatility
If only one HSDPA serving cell is configured for each UE in prior art, then the system architecture remains simple, but the HSDPA multiflow transmission feature cannot be effectively applied
Solution Approach 1:
The system transitions from a static single-cell configuration to a dynamic multi-cell configuration. The base station dynamically determines multiflow transmission capability information based on actual cell capabilities and reports this information to the RNC. The RNC then dynamically configures HSDPA multiflow transmission operations based on the reported capability information, allowing the system to adapt between single-cell and multi-cell modes as needed.
Solution Approach 2:
The invention changes the parameter of cell configuration from a fixed single-cell mode to a variable mode that can support multiple serving cells. By introducing multiflow transmission capability information as a new parameter and enabling the RNC to configure multiple HSDPA serving cells for a UE based on this parameter, the system achieves HSDPA multiflow transmission while maintaining manageable complexity through structured information exchange.
3Productivity
If the RNC lacks multiflow transmission capability information, then the admission control process remains simple, but the HSDPA multiflow transmission feature cannot be effectively applied
Solution Approach 1:
The base station acts as an intermediary that obtains multiflow transmission capability information from the network and reports it to the RNC. This intermediary role enables the RNC to acquire necessary capability information without directly managing base station resources, simplifying the overall system architecture while enabling HSDPA multiflow transmission configuration.
Solution Approach 2:
A feedback mechanism is established where the base station reports multiflow transmission capability information to the RNC based on actual cell capabilities. The RNC uses this feedback information to make informed configuration decisions for HSDPA multiflow transmission operations, improving configuration efficiency while maintaining manageable system complexity through structured information exchange.
