UERANSIM CLI Handover 解决方案
问题解决
错误: ERROR: No node found with name: 127.0.0.1
原因: UERANSIM CLI 不使用IP地址连接,而是使用节点名称。
正确的CLI使用方法
1. 查看所有可用节点
cd /home/uenr-3.2.7/ueransim
./build/nr-cli --dump
输出示例:
UERANSIM-gnb-286-1-1
imsi-286010000000001
imsi-286010000000002
imsi-286010000000003
imsi-286010000000004
imsi-286010000000005
2. 连接到gNB节点
# 错误的方法 (不要使用IP地址)
./build/nr-cli 127.0.0.1 -e help # ❌ 这会失败
# 正确的方法 (使用节点名称)
./build/nr-cli UERANSIM-gnb-286-1-1 -e commands # ✅ 正确
3. 查看可用命令
./build/nr-cli UERANSIM-gnb-286-1-1 -e commands
输出:
info | Show some information about the gNB
status | Show some status information about the gNB
amf-list | List all AMFs associated with the gNB
amf-info | Show some status information about the given AMF
ue-list | List all UEs associated with the gNB
ue-count | Print the total number of UEs connected the this gNB
ue-release | Request a UE context release for the given UE
handover | Trigger handover for a UE to target gNB
4. 使用Handover命令
查看handover语法:
./build/nr-cli UERANSIM-gnb-286-1-1 -e "handover"
输出:
Trigger handover for a UE to target gNB
Usage:
handover <ue-id> <target-gnb-id>
实际触发handover:
# 语法: handover <UE-ID> <目标gNB-ID>
./build/nr-cli UERANSIM-gnb-286-1-1 -e "handover 1 2"
完整的测试流程
步骤1: 启动环境
确保gNB和UE都在运行:
# 终端1: 启动gNB
./build/nr-gnb -c config/custom-gnb.yaml
# 终端2: 启动UE
./build/nr-ue -c config/custom-ue.yaml
步骤2: 检查连接状态
# 查看gNB信息
./build/nr-cli UERANSIM-gnb-286-1-1 -e "info"
# 查看连接的UE数量
./build/nr-cli UERANSIM-gnb-286-1-1 -e "ue-count"
# 列出连接的UE
./build/nr-cli UERANSIM-gnb-286-1-1 -e "ue-list"
步骤3: 触发Handover
# 格式: handover <ue-id> <target-gnb-id>
./build/nr-cli UERANSIM-gnb-286-1-1 -e "handover 1 2"
重要说明
- 节点发现机制: UERANSIM使用进程表
/tmp/UERANSIM.proc-table/来发现节点,不直接使用IP地址 - 节点名称: 必须使用确切的节点名称,如
UERANSIM-gnb-286-1-1 - UE状态: UE必须处于已注册并连接到gNB的状态才能执行handover
- 目标gNB: 需要有另一个运行的gNB作为handover目标
常用命令参考
# 列出所有节点
./build/nr-cli --dump
# 连接到gNB查看命令
./build/nr-cli UERANSIM-gnb-286-1-1 -e commands
# 查看gNB信息
./build/nr-cli UERANSIM-gnb-286-1-1 -e info
# 查看UE列表
./build/nr-cli UERANSIM-gnb-286-1-1 -e ue-list
# 触发handover
./build/nr-cli UERANSIM-gnb-286-1-1 -e "handover <ue-id> <target-gnb-id>"
# 查看UE状态
./build/nr-cli imsi-286010000000001 -e status
