Description
本发明涉及无线通信领域,尤其涉及一种数据传输方法、基站、终端及移动管理实体(mobile management entity,MME)。
智能仪表仪器等非由人操作的终端使用基于蜂窝的窄带物联网(narrowband Internet of Things,NB IoT)的无线接入技术(radio access technology,RAT)接入到网络。
现有技术中,在终端初始接入(Attach)网络过程中,移动管理实体(mobile management entity,MME)为终端选择唯一的数据传输方式。在初始接入网络之后,由于终端的无线资源控制(radio resource control,RRC)连接过程不受MME控制,因此终端的每次RRC连接过程中都只能采用MME为其选择的唯一的数据传输方式向基站发送数据。其中,MME选择的唯一的数据传输方式是通过用户面(user plane,UP)传输数据,或者是通过控制面(control plane,CP)传输数据。由于通过用户面传输数据的数据传输方式和通过控制面传输数据的数据传输方式各有利弊,终端的每次RRC连接过程中都只能采用MME为其选择的唯一的数据传输方式向基站发送数据,使得终端进行数据传输时采用的数据传输方式受到限制。
发明内容

所述基站接收所述终端采用所述第一传输方式发送的至少一个承载的数据。
这样,基站为终端选择终端向基站发送数据时所采用的第一传输方式,由于终端的RRC连接过程受基站控制,在终端的RRC连接过程中基站可以动态调整终端向基站发送数据时所采用的数据传输方式,避免终端每次RRC连接过程中都只能采用唯一的数据传输方式向基站发送数据。
其中,承载可以是指演进分组系统(evolved packet system,EPS)承载。至少一个承载可以包括全部承载中的部分承载,可以是一个承载或者多个承载,此时终端向基站发送这一个承载的数据或者这多个承载的数据时采用基站为终端选择的第一传输方式;至少一个承载也可以包括全部承载,此时终端向基站发送任意一个承载的数据时均采用基站为终端选择的第一传输方式。因此,本发明实施例可以实现针对不同的承载为终端选择用于终端向基站发送该承载的数据时所采用的数据传输方式。

实施例一
如图2所示,本发明实施例提供了一种数据传输方法,包括:
S201、基站为终端选择第一传输方式;
S202、基站向终端发送用于指示该第一传输方式的指示消息;
S203、终端采用该第一传输方式向基站发送至少一个承载的数据。
第一传输方式是指终端传输数据时所采用的传输方式,基站选择的第一传输方式是终端通过用户面传输数据或者终端通过控制面传输数据。
其中,终端通过用户面传输数据是指,终端使用数据无线承载(data radio bearer,DRB)将数据发送给基站,再由基站将接收的数据转发给服务网关(serving gate way,SGW),由SGW对终端发送的数据进行后续处理。终端通过控制面传输数据是指,终端使用信令无线承载(signaling radio bearer,SRB)将数据发送给基站,再由基站将接收的数据转发给MME,由MME对终端发送的数据进行后续处理。
承载可以是指EPS承载。至少一个承载可以包括全部承载中的部分承载,可以是一个承载或者多个承载,此时终端向基站发送这一个承载的数据或者这多个承载的数据时采用基站为终端选择的第一传输方式;至少一个承载也可以包括全部承载,此时终端向基站发送任意一个承载的数据时均采用基站为终端选择的第一传输方式。因此,通过本实施例提供的方法可以实现,针对不同的承载为基站选择用于终端向基站发送该承载的数据时所采用的不同的数据传输方式。
现有技术中,在终端初始接入(Attach)网络过程中,MME为终端选择唯一的数据传输方式。在初始接入网络之后,由于终端的RRC连接过程不受MME控制,因此终端的每次RRC连接过程中都只能采用MME为其选择的唯一的数据传输方式向基站发送数据。其中,MME选择的唯一的数据传输方式是终端通过用户面传输数据,或者是终端通过控制面传输数据。
终端通过用户面传输数据的数据传输方式和终端通过控制面传输数据的数据传输方式各有利弊。终端通过控制面传输数据的数据传输方式不需要建立用户面,因而此过程所需要的信令较少,但是终端通过控制面传输大量数
据时,会影响网络对信令的服务质量(quality of service,QoS)的保障。终端通过用户面传输数据的数据传输方式可以较好的保障系统中的信令的QoS,但是需要建立用户面,因而终端通过用户面传输数据的数据传输方式所需的信令较多。终端每次RRC连接过程中都只能采用MME为其选择的唯一的数据传输方式向基站发送数据,并没有考虑到上述两种数据传输方式的利弊,使得终端传输数据时采用的数据传输方式受到限制。
对比上述现有技术,由于终端的RRC连接过程受基站控制,因此本实施例中由基站为终端选择该终端向基站发送数据时所采用的数据传输方式,实现基站动态地将终端向基站发送数据时所采用的数据传输方式调整为基站为该终端选择的第一传输方式,避免终端的每次RRC连接过程中都只能采用MME为其选择的唯一的数据传输方式向基站发送数据,避免终端向基站发送数据时采用的数据传输方式受到限制。
需要说明的是,通过本实施例提供的方法,可以是对于终端的每个RRC连接过程基站为该终端选择一次数据传输方式,也可以是对于终端的多个RRC连接过程基站为该终端选择一次数据传输方式,还可以是在终端的一次RRC连接过程中基站多次为该终端选择数据传输方式。
本实施例中考虑到终端通过用户面传输数据的数据传输方式和终端通过控制面传输数据的数据传输方式各有利弊,基站可以通过以下方法实现基站为终端选择第一传输方式:
方法一
终端向基站发送用于指示至少一个承载的待发送数据量的指示消息;至少一个承载的待发送数据量可以包括该至少一个承载中每个承载分别对应的待发送数据量,也可以是指该至少一个承载中每个承载分别对应的待发送数据量之和。
基站根据终端指示的该至少一个承载的待发送数据量,为终端选择第一传输方式;考虑到终端通过用户面传输数据和终端通过控制面传输数据的利弊,终端的待发送数据量较多时,适合终端通过用户面传输数据,终端的待
发送数据量较少时,适合终端通过控制面传输数据。
因此,当该至少一个承载的待发送数据量大于或等于第一门限时,基站为终端选择的第一传输方式是终端通过用户面传输数据;或者,
当该至少一个承载的待发送数据量小于第一门限时,基站为终端选择的第一传输方式是终端通过控制面传输数据。例如,第一门限可以设置为一千字节。
若终端向基站指示的至少一个承载的待发送数据量包括该至少一个承载中每个承载分别对应的待发送数据量,则基站可以针对每个承载,根据该承载的待发送数据量,为终端选择终端发送该承载的数据时所采用的数据传输方式。
方法二
基站根据判断是否接收到MME发送的用于指示负载超标的指示消息的结果,为终端选择第一传输方式;
如果基站接收到该指示消息,则基站为终端选择终端通过用户面传输数据,基站接收到终端通过用户面发送的数据后,将接收的数据转发给SGW进行后续处理;否则,基站为终端选择终端通过控制面传输数据,基站接收到终端通过控制面发送的数据后,将接收的数据转发给MME进行后续处理。
方法三
基站根据自身的控制面负载和用户面负载为终端选择第一传输方式。
可选的,当基站的用户面负载与控制面负载的比值大于或等于第二门限时,第二门限可以设置为大于等于1的自然数,说明此时基站的用户面负载较大,基站为终端选择的第一传输方式是终端通过控制面传输数据;或者,当基站的用户面负载与控制面负载的比值小于第二门限时,说明此时基站的控制面负载较大,基站为终端选择的第一传输方式是终端通过用户面传输数据。
需要说明的是,基站也可以采用其他方法实现基站根据自身的控制面负载和用户面负载为终端选择第一传输方式,在此不做限定。例如,基站根据
自身的控制面负载与用户面负载的差值与预设门限的比较结果为终端选择的第一传输方式,等等。
方法四
MME为终端选择第一传输方式;该第一传输方式是终端通过用户面传输数据或者终端通过控制面传输数据;
MME向基站发送用于指示该第一传输方式的指示消息;
基站接收MME的指示消息,将MME为终端选择的第一传输方式确定为基站为终端选择的第一传输方式。
此方法与现有技术的区别在于:现有技术中MME为终端选择唯一的数据传输方式,终端的每次RRC连接过程中都只能采用MME为其选择的唯一的数据传输方式向基站发送数据。而此方法中,基站根据MME的指示消息为终端选择第一传输方式,由于终端的RRC连接过程受基站的控制,在终端的RRC连接过程中基站可以动态地将终端向基站发送数据时所采用的数据传输方式调整为该第一传输方式。
可选的,MME根据判断自身负载是否超标的结果,为终端选择第一传输方式;
如果MME的负载超标,则MME为终端选择的第一传输方式是终端通过用户面传输数据;否则,MME为终端选择的第一传输方式是终端通过控制面传输数据。
本实施例中,可选的,在基站为终端选择第一传输方式之前,基站接收MME发送的指示消息,或者,基站接收终端发送的指示消息;
其中,指示消息用于指示MME允许终端采用两种传输方式中的任一种向基站发送至少一个承载的数据,两种传输方式是终端通过用户面传输数据和终端通过控制面传输数据。
这样,基站在得知MME允许终端采用两种传输方式中的任一种向基站发送至少一个承载的数据后,才能为终端选择这两种传输方式中的任一种传输方式。
可选的,在基站接收MME发送的上述指示消息之前,终端向MME发送指示消息,该指示消息用于指示终端支持采用上述两种传输方式中的任一种发送至少一个承载的数据,MME根据终端的指示消息,确定MME允许终端采用两种传输方式中的任一种向基站发送至少一个承载的数据。
可选的,在基站接收终端发送的指示消息之前,终端向MME发送指示消息,该指示消息用于指示终端支持采用上述两种传输方式中的任一种发送至少一个承载的数据,MME根据终端的指示消息,确定MME允许终端采用两种传输方式中的任一种向基站发送至少一个承载的数据,并向终端指示MME允许终端采用两种传输方式中的任一种向基站发送至少一个承载的数据。
下面举例说明本实施例提供的一种数据传输方法。
举例说明一
以终端的RRC连接建立过程为例,如图3所示的本实施例提供的一种数据传输方法,S301中终端向基站发送的RRC连接请求消息携带至少一个承载的待发送数据量;S302中基站向终端发送的RRC连接建立消息携带第一传输方式,该第一传输方式是基站根据终端指示的至少一个承载的待发送数据量为终端选择的。
若基站为终端选择的第一传输方式是终端通过控制面传输数据,则S303中终端向基站发送的RRC连接建立完成消息携带该至少一个承载的数据,S304中基站向MME发送的初始终端消息携带该至少一个承载的数据。
若基站为终端选择的第一传输方式是终端通过用户面传输数据,则终端缓存该至少一个承载的数据,直到通过S305和S306中MME和基站为该终端建立用户面之后,S307中终端通过用户面向基站发送该至少一个承载的数据,S308中基站将该至少一个承载的数据转发给SGW。
举例说明二
以终端的RRC连接建立过程为例,如图4所示的本实施例提供的一种数据传输方法,图4所示的方法与图3所示的方法的区别在于,在S401中终端向MME发送的连接(Attach)请求消息指示,终端支持采用两种传输方式中
的任一种发送至少一个承载的数据,该两种传输方式包括终端通过用户面传输数据和终端通过控制面传输数据,在S402中MME向终端发送的连接(Attach)接受消息指示,MME允许终端支持采用两种传输方式中的任一种发送至少一个承载的数据,该两种传输方式包括终端通过用户面传输数据和终端通过控制面传输数据。图4所示的方法与图3所示的方法的重叠内容,在此不再赘述。
举例说明三
以终端的RRC连接恢复过程为例,如图5所示的本实施例提供的一种数据传输方法,S501中终端向基站发送的RRC连接恢复请求消息携带至少一个承载的待发送数据量;S502中基站向终端发送的RRC连接恢复消息携带第一传输方式,该第一传输方式是基站根据终端指示的至少一个承载的待发送数据量为终端选择的。
若基站为终端选择的第一传输方式是终端通过控制面传输数据,则S503中终端向基站发送的RRC连接恢复完成消息携带该至少一个承载的数据,S504中基站向MME发送的初始终端消息携带该至少一个承载的数据。
若基站为终端选择的第一传输方式是终端通过用户面传输数据,则S505中终端通过用户面向基站发送该至少一个承载的数据,S506中基站将该至少一个承载的数据转发给SGW。
上述举例说明中,针对不同的承载,基站为终端选择的用于终端向基站发送承载的数据时所采用的第一传输方式可以相同也可以不同。终端可以向基站指示某一个承载的待发送数据量,也可以向基站指示多个承载中每个承载的待发送数据量,在此不做限定。
本发明实施例提供的一种数据传输方法中,考虑到终端的RRC连接过程受基站控制,因此由基站为终端选择终端向基站发送数据时所采用的第一传输方式,并向终端指示基站选择的该第一传输方式,实现基站动态地将终端向基站发送数据时所采用的数据传输方式调整为基站为该终端选择的第一传输方式,避免终端的每次RRC连接过程中都只能采用MME为其选择的唯一
的数据传输方式向基站发送数据,避免终端向基站发送数据时采用的数据传输方式受到限制。基站在为终端选择第一传输方式的过程中,考虑到终端通过用户面传输数据的数据传输方式和终端通过控制面传输数据的数据传输方式各有利弊,因此能够更好的利用通过用户面传输数据和通过控制面传输数据这两种数据传输方式的优势,避免这两种数据传输方式的劣势。
