From the document, here are the details on **SDCCH Congestion Rate** and related
parameters:
### **SDCCH Congestion Rate**
- **Definition**: The percentage of failed SDCCH seizures due to busy SDCCH
channels.
- **Formula**:
$$
\text{SDCCH Congestion Rate} = \frac{\text{Failed SDCCH Seizures due to Busy
SDCCH}}{\text{Total SDCCH Seizure Requests}} \times 100\%
$$
### **Key Parameters**
1. **SDCCH Allocation**:
- **Parameter Name**: `SDCCH/8`
- **Proposal Value**: Increase the number of SDCCH channels if the current
allocation is insufficient to handle the traffic.
2. **Dynamic SDCCH Allocation**:
- **Parameter Name**: `DYN_SDCCH_ALLOC`
- **Proposal Value**: Enable dynamic allocation to adjust the number of SDCCH
channels based on real-time traffic demands.
3. **SDCCH Congestion Threshold**:
- **Parameter Name**: `SDCCH_CONG_THR`
- **Proposal Value**: Set a threshold value (e.g., 1-2%) to trigger alarms when
congestion exceeds this limit.
4. **SDCCH Queue Length**:
- **Parameter Name**: `SDCCH_QUEUE_LEN`
- **Proposal Value**: Adjust the queue length to ensure that requests are not
dropped immediately when all channels are busy.
By monitoring and optimizing these parameters, you can effectively manage and
reduce SDCCH congestion in your network.
