Carrier Aggregation Configuration via MCC and MNC
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing number of LTE frequency bands and supported carrier aggregation (CA) combinations in electronic devices leads to a redundant load, which affects their performance and efficiency.
Innovation Solution
A CA-based configuration method that determines target information including mobile country code (MCC) and/or mobile network code (MNC), selects a suitable CA combination from supported sets, and sends a request to an operator server for network configuration, thereby optimizing CA combinations to reduce redundancy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the electronic device supports an increasing number of CA combinations to accommodate more LTE frequency bands, then the adaptability and versatility of the device is improved, but the device complexity and redundant load increase
Solution Approach 1:
The operator server pre-configures multiple CA combinations and stores them in the HSS database before the electronic device needs them. When the device attaches to the network, the MME retrieves the appropriate pre-configured CA combination based on the device's MCC and MNC information, eliminating the need for the device to manually support and manage all possible CA combinations locally.
Solution Approach 2:
The MME acts as an intermediary between the HSS database and the electronic device. It retrieves CA combination information from the HSS based on the device's subscriber information and forwards the appropriate CA configuration to the device, thereby shielding the device from the complexity of managing numerous CA combinations directly.
2Adaptability or versatility
If the electronic device supports all possible CA combinations, then the adaptability to different network environments is improved, but the performance and efficiency deteriorate due to redundant load
Solution Approach 1:
Instead of uniformly supporting all CA combinations across all devices, the system provides localized CA configuration tailored to each device's specific MCC and MNC information. Each device receives only the CA combinations relevant to its home network and roaming partners, eliminating unnecessary redundant load while maintaining adaptability to appropriate network environments.
3Ease of operation
If the electronic device manually configures CA combinations, then the ease of operation is reduced, but the flexibility and control are improved
Solution Approach 1:
The system enables self-service CA configuration where the electronic device automatically receives and applies CA combination configurations from the network side without manual user intervention. The device's identity information (MCC/MNC) automatically triggers the appropriate CA configuration retrieval and application, combining ease of operation with network-controlled flexibility.

AI summary
A configuration aggregation (CA)-based configuration method and related devices are provided, which are applicable to an electronic device. The method includes the following. Target information is determined, where the target information includes a mobile country code (MCC) and/or a mobile network code (MNC). A target set is determined according to the target information, where the target set includes multiple CA combinations supported by the electronic device. A target request is sent to an operator server, where the target request carries the target set, and the target request is used to instruct to select from the target set a CA combination for network configuration. A target CA combination is received, where the target CA combination is sent by the operator server in response to the target request. Network configuration is performed according to the target CA combination.
