Description

通信方法和装置
本申请要求于2021年10月09日提交中国专利局、申请号为202111175630.9、申请名称为“通信方法和装置”的中国专利申请的优先权,其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信技术领域,并且更具体地,涉及一种通信方法和装置。
背景技术
在当前无线网络中,由于每个设备(如基站)传输的管理面本端网络协议(internet protocol,IP)地址、信令面本端IP地址、用户面本端IP地址、因特网密钥交换(internet key exchange,IKE)本端IP地址等不同,另外,由于传输承载网的差异,每个设备的虚拟局域网(virtual local area network,VLAN)、接口IP、路由也不同,因此需要对每个设备规划传输相关的配置参数,花费时间比较长。另外,如果对传输承载网进行传输调整,每个设备也必须重新规划调整,无法自适应,浪费人力。
互联网协议版本6(internet protocol version 6,IPv6)支持采用无状态地址配置(stateless address autoconfiguration,SLAAC)技术自动生成IP地址。当主机上线后,主机会发送路由器请求(router solicit,RS)消息给路由器,请求地址配置;路由器收到RS消息后发送路由器通告(router advertisement,RA)消息给主机,其中携带有用来进行地址自动配置的前缀等信息;主机收到RA消息后,获得地址前缀信息,还有地址相关的参数信息,根据SLAAC规定的方法自动生成IPv6地址。
然而,当一个主机支持多种业务类型,且多种业务类型使用多个IP地址时,主机无法确定采用SLAAC技术自动生成的IP地址适用的业务类型。例如,如图2所示,当主机生成IP地址#1时,主机无法确定IP地址#1适用于哪一种业务类型。因此,如何确定自动生成的IP地址适用的业务类型是一个亟待解决的问题。
发明内容
本申请提供一种通信方法和装置,使得主机可以确定自动生成的IP地址适用的业务类型。
第一方面,提供了一种通信方法,包括:
第一网元从网络管理网元第一对应关系,第一对应关系为互联网协议IP地址的用途标识和IP地址适用的业务类型之间的对应关系。第一网元从网络管理网元获取第一信息,第一信息包括第一IP地址的用途标识。第一网元根据第一对应关系以及第一IP地址的用途标识,确定第一IP地址适用的业务类型。
