B123、终端在第N代移动通信系统下,接收第三核心网节点发送的所述第一业务在第M代移动通信系统下对应的目标参数的目标值;
可选地,该第三核心网节点为SMF、PDN网关(PDN GateWay,PGW)或同时实现PGW和SMF功能的SMF+PGW网元。
此种情况下,终端在该第N代移动通信系统下,接收第三核心网节点发送的所述第一业务在第M代移动通信系统下对应承载的建立或修改时,发送的目标值;具体地,第三核心网节点通过公用数据网(Public Data Network,PDN)连接建立或PDN连接修改消息的协议配置选项(Protocol Configuration Options,PCO)字段中携带该目标值。
B124、终端在移动到第M代移动通信系统内执行注册时,接收第四核心网节点发送的第一业务在第M代移动通信系统下对应的目标参数的目标值;
需要说明的是,该第四核心网节点为接入移动管理功能(Access and Mobility Management Function,AMF)。
此种情况指的是,在本次移动过程中,在终端在第M代移动通信系统内执行注册时,会向AMF发送注册请求,AMF会反馈注册接受消息,通常该注册接受消息中会携带第一业务在第M代移动通信系统下对应的目标参数的目标值。
B13、所述终端在进行IP多媒体系统(IP Multimedia Subsystem,IMS)注册或第一业 务对应的会话建立时,接收第二核心网节点发送的的目标参数的第二值;
需要说明的是,此种情况是终端首次注册到IMS或第一业务对应的会话初次建立时,第二核心网节点发送给终端的。因该目标参数是在IMS注册或第一业务对应的会话建立时获取的,所以该目标参数是较为精确的,终端可以直接使用。可选地,该第二核心网节点可以为服务呼叫会话控制功能(Serving Call Session Control Function,S-CSCF)。
可选地,该修改请求包括:会话初始协议(Session Initiation Protocol,SIP)重邀请(re-Invite)请求消息,所述SIP重邀请请求消息中携带所述目标参数的第二值。
可选地,本申请的另一实施例中,所述终端获取第一业务的目标参数的第二值的实现方式,包括:
所述终端在确定存在第一业务的传输的情况下,获取第一业务的目标参数的第二值。
需要说明的是,终端存在第一业务的传输可以理解为终端正在传输该第一业务。
可选地,所述终端确定存在第一业务的传输的实现方式,包括:
所述终端根据已建立的至少一个承载的服务质量(Quality of Service,QoS)参数,确定存在第一业务的传输。
可选地,本申请的一实施例中,所述确定存在第一业务的传输,包括:
所述终端根据所述QoS参数的QoS等级标识(QoS Class Identifier,QCI),确定存在第一业务的传输;
其中,在所述QoS等级标识为第一取值的情况下,所述第一业务为语音业务;或者,
在所述QoS等级标识为第二取值的情况下,所述第一业务为视频业务;
所述第一取值不同于所述第二取值。
可以理解为,若述QoS参数中存在第一业务所对应的QCI,则可以终端确定存在第一业务的传输。
需要说明的是,该第一取值和第二取值可以是网络侧配置、终端内预配置或协议约定的。
例如,QoS等级标识为1的情况下,第一承载用于传输的业务为语音业务;QoS等级标识为2的情况下,所述第一承载用于传输的业务为视频业务。
本申请中的语音业务也可以称为语音呼叫(voice call)业务,视频业务也可以称为视频呼叫(video call)业务。
例如,在5G下,终端利用演进的分组系统(Evolved Packet System,EPS)承载进行终端的语音业务的传输,5G下支持的GBR为512kbps,终端在4G中使用的GBR为128kbps,当终端由4G移动到5G时,因在5G和4G下使用的GBR不一样,此时,终端向第一核心网节点发送修改请求,以将使用的参数修改为512kbps,后续的通信的双方都使用512kbps进行语音业务的传输。
下面对本申请上述实施例的具体应用进行详细说明如下。
如图4所示,具体步骤如下:
步骤S401,终端从4G移动到5G时,终端确定语音业务在5G对应的目标参数的第二值,当目标参数的第二值与目标参数的当前取值不同时,终端确定满足修改条件。
步骤S402,终端通过代理呼叫会话控制功能(Proxy-Call Session Control Function,P-CSCF)向S-CSCF发送SIP re-Invite请求消息;
该SIP re-Invite请求消息中携带目标参数的第二值。
需要说明的是,该SIP re-Invite请求消息需要先发送给5G下的基站,然后由基站发送给AMF,通过AMF发送给SMF,然后由SMF转发给P-CSCF。
步骤S403,S-CSCF接受该目标参数的第二值,通过P-CSCF向S-CSCF发送确认信息,该确认信息用于指示S-CSCF基于目标参数的第二值进行数据传输;
例如,S-CSCF反馈200OK给终端。
需要说明的是,本申请的至少一个实施例,在终端移动到5G后,可以享受更好的服务质量,增强了用户体验。
对应于终端侧的实现,如图5所示,本申请实施例提供一种通信方法,包括:
步骤501,第一核心网节点接收修改请求,所述修改请求用于将终端的第一业务的目标参数的第一值修改为第二值;

    终端在移动到第M代移动通信系统内执行注册时,接收第四核心网节点发送的第一业务在第M代移动通信系统下对应的目标参数的目标值。
  17. 根据权利要求15所述的装置,其中,所述修改请求包括:会话初始协议SIP重邀请请求消息,所述SIP重邀请请求消息中携带所述目标参数的第二值。
  18. 根据权利要求15所述的装置,其中,所述第一业务的目标参数的第二值的获取方式,包括:
    在确定存在第一业务的传输的情况下,获取第一业务的目标参数的第二值。
  19. 根据权利要求18所述的装置,其中,所述确定存在第一业务的传输的实现方式,包括:
    所述终端根据已建立的至少一个承载的服务质量QoS参数,确定存在第一业务的传输。
  20. 根据权利要求19所述的装置,其中,所述确定存在第一业务的传输的实现方式,包括:
    根据所述QoS参数的QoS等级标识,确定存在第一业务的传输;
    其中,在所述QoS等级标识为第一取值的情况下,所述第一业务为语音业务;或者,
    在所述QoS等级标识为第二取值的情况下,所述第一业务为视频业务;
    所述第一取值不同于所述第二取值。
  21. 一种通信装置,应用于第一核心网节点,包括:
    接收模块,用于接收修改请求,所述修改请求用于将终端的第一业务的目标参数的第一值修改为第二值;
    反馈模块,用于向终端反馈确认信息,所述确认信息用于指示第一核心网节点基于目标参数的第二值进行数据传输;
    其中,所述第一值为终端在第N代移动通信系统中的第一业务对应的目标参数的取值,所述第二值为所述第一业务在第M代移动通信系统下对应的目标参数的取值,M大于N。
  22. 根据权利要求21所述的装置,其中,所述修改请求包括:会话初始协议SIP重邀 请请求消息,所述SIP重邀请请求消息中携带所述目标参数的第二值。
  23. 一种通信设备,包括处理器和存储器,所述存储器存储可在所述处理器上运行的程序或指令,所述程序或指令被所述处理器执行时实现如权利要求1至14任一项所述的通信方法的步骤。
  24. 一种可读存储介质,所述可读存储介质上存储程序或指令,所述程序或指令被处理器执行时实现如权利要求1至14任一项所述的通信方法的步骤。
