用python画出由UE端发起的释放EPS承载的流程图,在图中展示信令Attach success/connection success等信令

为了画出流程图,我们可以使用Python中的工具包graphviz
。首先需要安装graphviz
,使用以下命令:
pip install graphviz
接下来,我们可以使用以下代码来画出由UE端发起的释放EPS承载的流程图,并在图中展示信令Attach success/connection success等信令:
from graphviz import Digraph
# 创建Digraph对象
dot = Digraph(comment='EPS Release Procedure')
# 添加节点
dot.node('UE', 'UE')
dot.node('eNodeB', 'eNodeB')
dot.node('MME', 'MME')
dot.node('SGW', 'SGW')
dot.node('PGW', 'PGW')
# 添加边
dot.edge('UE', 'eNodeB', label='Attach Request')
dot.edge('eNodeB', 'MME', label='S1AP Initial UE Message')
dot.edge('MME', 'SGW', label='Create Session Request')
dot.edge('SGW', 'PGW', label='Create Session Request')
dot.edge('PGW', 'SGW', label='Create Session Response')
dot.edge('SGW', 'MME', label='Create Session Response')
dot.edge('MME', 'eNodeB', label='S1AP Initial Context Setup Request')
dot.edge('eNodeB', 'UE', label='Attach Accept')
dot.edge('UE', 'eNodeB', label='Attach Complete')
dot.edge('eNodeB', 'MME', label='S1AP UE Context Release Request')
dot.edge('MME', 'SGW', label='Delete Session Request')
dot.edge('SGW', 'PGW', label='Delete Session Request')
dot.edge('PGW', 'SGW', label='Delete Session Response')
dot.edge('SGW', 'MME', label='Delete Session Response')
dot.edge('MME', 'eNodeB', label='S1AP UE Context Release Command')
dot.edge('eNodeB', 'UE', label='Detach Request')
dot.edge('UE', 'eNodeB', label='Detach Accept')
# 输出图像
dot.render('eps_release.gv', view=True)
这段代码会生成一个名为eps_release.gv
的文件,可以使用Graphviz软件打开该文件来查看流程图。在流程图中,我们使用了label
属性来展示信令Attach Request、S1AP Initial UE Message、Create Session Request等。
