In the continuous evolution of mobile communication systems, multi-frequency networking has become a key strategy for optimizing network performance and meeting diverse user needs. In real application scenarios, various frequency bands coexist, such as 700M, 800M, 900M, 1.8G, and 2.6G. Proper planning of the usage of each frequency band is crucial for improving overall network efficiency. A common networking strategy is to let low-frequency bands like 700M, 800M, and 900M mainly carry voice services, while mid to high-frequency bands are responsible for data services. Achieving this strategy requires meticulous parameter configuration.

1. Inter-Frequency Handover Grouping

Inter-frequency handover grouping is the foundation for achieving voice and data separation. By reasonably dividing handover groups, precise and efficient switching between different frequency bands can be ensured. For example, grouping the low-frequency bands of 700M, 800M, and 900M together allows for parameter optimization for mobility management of voice services, setting relatively conservative handover thresholds to reduce unnecessary handovers and ensure continuity and stability of voice calls. For mid to high-frequency bands, based on the characteristics of data services, such as rate and throughput requirements, more flexible handover parameters are set, allowing terminals to quickly connect to mid to high-frequency cells with better signal quality during movement, ensuring smooth data transmission.

2. Base Station Cell Function Switch

The base station cell function switch determines the cell’s operating mode and service carrying capacity. In a voice and data separated networking scheme, specific functions must be activated to support low-frequency carrying voice and high-frequency carrying data. Taking low-frequency cells as an example, enabling the voice service optimization function switch enhances voice signal processing capabilities and improves voice quality; disabling the data service acceleration function for low-frequency cells prevents data services from occupying precious low-frequency resources. Conversely, mid to high-frequency cells should enable data service acceleration and carrier aggregation functions to enhance data transmission rates, while disabling voice enhancement functions that are not applicable to data services, achieving efficient resource utilization.

3. QCI Parameters

QCI (Quality Class Identifier) parameters play a key role in ensuring service quality for different business types. Voice services correspond to specific QCI values, such as QCI1, which must be configured to ensure high priority, low latency, and low packet loss requirements. To meet the real-time nature of voice, a shorter scheduling cycle should be set to ensure timely sending of voice packets. For data services, different types of data services correspond to different QCI values, such as web browsing and video streaming, with corresponding bandwidth, latency, and packet loss parameters set based on their service characteristics. For video services, a higher bandwidth guarantee and relatively relaxed latency requirements are configured to ensure smooth video playback.

4. Multi-Frequency Measurement Control

Multi-frequency measurement control is used to guide terminals to measure signals from different frequency bands, providing a basis for handover decisions. In a multi-frequency networking environment, terminals need to measure signal strength and quality across various frequency bands promptly and accurately. The network side controls terminal measurement behavior through multi-frequency measurement control parameters, such as measurement cycles and measurement thresholds. For low-frequency bands, a longer measurement cycle is set to reduce terminal power consumption, as low-frequency signals have wide coverage and high stability; for mid to high-frequency bands, a shorter measurement cycle is set to quickly capture signal changes, responding to the rapid changes in signal quality required by data services. When a terminal measures that a certain frequency band’s signal meets the handover conditions, it triggers the handover process, enabling reasonable migration of services between different frequency bands.
