Description

一种消减网络设备传输带宽的方法及设备 技术领域
本申请涉及移动网络通信技术领域，尤其涉及一种消减网络设备传输带宽的方法及设备。
背景技术
对于移动类终端设备而言，续航是一个重要指标，移动类终端设备必须支持必要的低功率方案。目前，在4G以及5G通信系统中普遍使用的低功耗方案是非连续接收(discontinuous reception，DRX)技术方案。
DRX技术是一种用于降低终端功耗的低功耗技术。在DRX模式下，为了实现终端连续接收，终端预先配置固定的睡眠周期。在DRX模式下包括唤醒(wake up)模式和睡眠(sleep)模式，若网络侧与终端之间有数据传输，终端工作于唤醒模式下，终端处于功率消耗模式下；若网络侧与终端之间没有数据传输，终端工作于睡眠模式下，终端处于功率节省模式下。
随着5G通信系统中数据调度越来越频繁，网络侧与终端之间进行频繁的数据传输导致终端始终工作于唤醒模式下，而无法进入功率节省模式下工作，最终，在数据调度频繁的5G通信系统中，现有DRX技术降低终端功耗的效果不佳，导致终端续航能力降低。
发明内容

从上述第一方面的技术方案中可以看出，通过网络设备向终端发送传输带宽消减配置信息,并且终端向网络设备上报该终端期望的服务小区的目标传输带宽消减系数，以使得网络设备可以根据上述终端上报的目标传输带宽消减系数消减为该终端提供服务的服务小区的传输带宽，从而减少网络设备调度终端的传输带宽，降低终端功耗，提升终端续航能力。
结合上述第一方面，在本申请实施例第一方面的第一种可能的实现方式中，该终端接收网络设备发送的传输带宽配置信息，可以包括：终端接收网络设备通过无线资源控制重配置消息发送的传输带宽配置信息；此种情况下，终端可以通过终端辅助信息消息发送目标传输带宽消减系数给网络设备，或者，终端也可以通过媒体访问控制层控制单元发送该目标传输带宽消减系数给网络设备。从上述第一方面的第一种可能的实现方式中，通过无线资源控制重配置消息为终端配置传输带宽配置信息，以及在通过无线资源控制重配置消息进行传输带宽配置的同时，终端通过终端辅助信息消息或媒体访问控制层控制单元上报目标传输带宽消减系数，可以使得本申请中消减网络设备传输带宽的方法通过对无线资源控制重 配置消息、终端辅助信息消息以及媒体访问控制层控制单元进行适当扩展便可以实现，更易于实现。
结合上述第一方面或第一方面的第一种可能的实现方式，在本申请实施例第一方面的第二种可能的实现方式中，上述传输带宽配置信息包括：连续发送目标传输带宽消减系数的最小时间间隔，应理解，此种情况下，网络设备和终端支持的传输带宽消减系数可以是提前预设的。从上述第一方面的第二种可能的实现方式中可以看出，网络设备将连续发送目标传输带宽消减系数的最小时间间隔告知终端，以便终端依据此最小时间间隔上报目标传输带宽消减系数，可以防止终端频繁的上报传输带宽消减系数对网络设备造成冲击。

具体实施方式
下面结合附图，对本申请的实施例进行描述，显然，所描述的实施例仅仅是本申请一部分的实施例，而不是全部的实施例。本领域普通技术人员可知，随着技术的发展和新场景的出现，本申请实施例提供的技术方案对于类似的技术问题，同样适用。
本申请实施例提供了一种消减网络传输带宽的方法及设备，适用于移动网络通信技术领域，用于通过减少网络设备传输带宽实现，以降低终端功耗，提升终端续航能力的目的。
本申请实施例中所涉及到的终端可以包括各种具有无线通信功能的手持设备、车载设备、可穿戴设备、计算设备或连接到无线调制解调器的其它处理设备。所述终端可以是移动站(Mobile Station，MS)、用户模块(subscriber unit)、蜂窝电话(cellular phone)、智能电话(smart phone)、无线数据卡、个人数字助理(Personal Digital Assistant，简称：PDA)电脑、平板型电脑、无线调制解调器(modem)、手持设备(handset)、膝上型电脑(laptop computer)、机器类型通信(Machine Type Communication,MTC)终端等。
接入网设备可以是LTE系统、NR系统或者授权辅助接入长期演进(Authorized auxiliary access long-term evolution，LAA-LTE)系统中的演进型基站(Evolutional Node B，简称可以为eNB或e-NodeB) 宏基站、微基站(也称为“小基站”)、微微基站、接入站点(Access Point，AP)、传输站点(Transmission Point，TP)或gNodeB(new generation Node B，新一代基站)等。
如上文中所述，DRX技术是一种用于降低终端功耗的低功耗技术。图1a为DRX周期的一个结构示意图，如图1a所示，一个DRX周期包括监听时间段和睡眠时间段，在DRX周期中的监听时间段，终端工作于在唤醒模式下监听网络调度，在DRX周期中的睡眠时间段，终端工作于睡眠模式下不对网络调度进行监听，以降低功耗。媒体访问控制层控制单元(medium access control control element，MAC CE)是用来传输MAC层的控制消息，在MAC层中除传输来自MAC层的上层数据之外，还会在MAC包中传输MAC CE来实现传输控制功能。
在网络组网中，无论采用哪种组网方式，都可以通过双连接(dual connectivity，DC)技术，提高无线资源利用率，提高网络传输速率。随着网络传输速率的不断提高，现有的降低终端功耗的低功耗技术降低终端功耗的效果不佳，例如在终端处于双连接状态下，网络侧与终端之间的数据调度频繁，DRX技术无法达到降低功耗的预期效果，最终，导致终端续航能力降低，无法满足对终端的续航能力要求，尤其是移动类终端设备。
在双连接状态下，引入了小区组的概念。具体来说，图1b为本申请实施例中提供的一个双连接示意图，如图1b所示，在双连接状态下，终端同时接入到两个独立配置的的小区组中，其中，上述两个小区组中一个称之为主小区组(Master Cell Group，MCG)，另一个称之为辅小区组(Secondary Cell Group，SCG)，主小区组和辅小区组中均包括一个主小区和多个辅小区，其中，主小区组中的主小区称之为(Primary Cell，PCell)，辅小区组中的主小区称之为(Primary Secondary Cell，PSCell)，主小区组和辅小区组中的辅小区均称之为(Secondary Cell，SCell)，图1b中示出的主小区组包括一个主小区和三个辅小区，其辅小区组包括一个主小区和两个辅小区。
图2为本申请实施例提供的一个无线通信系统。
如图1b所示，该无线通信系统中包括：终端201和网络设备202；
网络设备202向终端201发送传输带宽消减配置信息，该传输带宽消减配置信息包括网络设备支持的传输带宽消减的参数集合；在终端201接收到上述传输带宽消减配置信息之后，终端201向网络设备202发送目标传输带宽消减系数，该目标传输带宽消减系数为终端期望的服务小区的传输带宽消减系数，服务小区包括当前为终端提供服务的所有小区；在网络设备202接收到上述目标传输带宽消减系数之后，网络设备202根据该目标传输带宽消减系数消减服务小区的传输带宽。
在一种实施方式中，网络设备202向终端201进行传输带宽消减配置的配置方式具体可以是：网络设备202通过无线资源控制(radio resource control，RRC)重配置消息承载上述传输带宽消减配置信息发送至终端201。
在终端201通过无线资源控制重配置消息接收到网络设备202发送的传输带宽消减配置信息的情况下，终端201需要向网络设备202回复目标带宽消减系数，具体信息承载方式可以包括以下两种。需要说明的是，网络设备202还可以通过除无线资源控制重配置消息之外的其他消息为终端进行传输带宽消减配置，本申请对此不做具体限定。
第一种信息承载方式：网络设备202通过无线资源控制重配置消息中的其他配置信息(OtherConfig)为终端201进行传输带宽消减配置，终端201通过终端辅助信息消息承载目标传输带宽消减系数发送至网络设备202。
第二种信息承载方式：网络设备202通过无线资源控制重配置消息中的主小区配置(SpCellConfig)信息为终端201进行传输带宽消减配置，，终端201通过媒体访问控制层控制单元(medium access  control control element，MAC CE)承载目标传输带宽消减系数发送至网络设备202。
在网络设备202为终端201配置的传输带宽消减配置信息中，第一种配置方式：网络设备202将连续发送目标传输带宽消减系数的最小传输时间间隔配置给终端201，具体的，上述连续发送目标传输带宽消减系数的最小传输时间间隔携带于上述传输带宽消减配置消息中；第二种配置方式：网络设备202将连续发送目标传输带宽消减系数的最小传输时间间隔以及网络设备202支持的传输带宽消减的参数集合配置给终端201。
上述实施方式中所述的目标传输带宽消减系数具体可以包括但不限于以下三种方式：
第一种传输带宽消减方式：目标传输带宽消减系数包括多个传输带宽消减系数，每一个传输带宽消减系数对应一个为终端201提供服务的一个服务小区，传输带宽消减系数的数量与为终端201提供服务的服务小区数量相等，例如，若为终端201提供服务的服务小区数量为5个，上述目标带宽消减系数中包括5个带宽消减系数，5个服务小区各自对应5个带宽消减系数中的一个；
第二种传输带宽消减方式：目标传输带宽消减系数包括一个传输带宽消减系数，该传输带宽消减系数与为终端201提供服务的所有服务小区对应；
第三种传输带宽消减方式：目标传输带宽消减系数包括一个传输带宽消减系数，该传输带宽消减系数于为终端201提供服务的所有服务小区的带宽总和对应。
为了便于理解本申请实施例中消减网络设备传输带宽的方法，下面分别结合上文中所述的第一种响应方式和第二种响应方式进行详细说明。
第一种信息承载方式：传输带宽消减配置信息承载于无线资源控制重配置消息中的其他配置(OtherConfig)信息中，目标传输带宽消减系数承载于终端辅助信息消息中。
图3为本申请实施例提供的消减网络设备传输带宽的方法的一个实施例示意图。
301、基站通过无线资源控制重配置消息中的其他配置信息为终端进行传输带宽消减配置。
通过对无线资源控制重配置消息中其他配置(OtherConfig)信息进行扩展，以表示基站支持网络传输带宽消减，同时配置两次网络传输带宽消减系数上报的最小时间间隔。
具体来说，在无线资源控制重配置消息中其他配置(OtherConfig)信息中新增加传输带宽消减配置信息，以用于指示基站支持网络传输带宽消减，一方面，若基站支持的网络传输带宽消减系数是基站和终端预先协商好的，基站配置的传输带宽消减配置信息中携带有两次网络传输带宽消减系数上报的最小时间间隔，例如，基站配置的传输带宽消减配置信息中携带终端连续两次发送目标传输带宽消减系数的最小时间间隔；另一方面，若对于基站支持的网络传输带宽消减系数，基站和终端没有预先协商，基站配置的传输带宽消减配置信息中除携带有两次网络传输带宽消减系数上报的最小时间间隔之外，还携带有基站支持的网络传输带宽消减系数，例如，基站配置的传输带宽消减配置信息携带终端连续两次发送目标传输带宽消减系数的最小时间间隔以及基站支持的传输带宽消减系数对应的参数集合。
302、终端通过终端辅助控制信息消息通知基站对服务小区的带宽进行调度消减。
通过对终端辅助控制信息消息进行扩展传输带宽消减指示，以指示基站对为终端提供服务的服务小区进行传输带宽消减。
具体来说，终端在终端辅助控制信息消息中通知基站进行传输带宽消减具体可以采用但不限于以下三种传输带宽消减指示方式，第一种指示方式：与上述第一种传输带宽消减方式对应，终端在终端辅助控制信息消息中通知基站在终端对应的小区组内的部分或者全部服务小区上进行调度消减；第二种指示方式：与上述第二种传输带宽消减方式对应，终端在终端辅助控制信息消息中通知基站对所有为终端提供服务的服务小区进行调度消减，并且指示所有服务小区使用相同的传输带宽消减系数；第三种指示方 式：终端在终端辅助控制信息消息中通知基站对小区组内所有服务小区的带宽总和进行调度消减，其中，不同服务小区的传输带宽消减系数由基站根据不同小区的实际情况进行分配。
进一步，以终端提供服务的小区为图1b中所示的主小区组中主小区、辅小区1和辅小区2为例，对上述三种传输带宽消减方式进行说明：
首先，对上述第一种传输带宽消减方式进行说明，图4为本申请实施例中终端上报每一个服务小区的消减系数时对应的一个传输带宽消减示意图；如图4所示，针对每一次传输带宽消减，终端通过终端辅助控制信息消息上报三个传输带宽消减系数，其分别为：主小区的消减系数1、辅小区1的消减系数2和辅小区2的消减系数3，最终，基站根据终端上报的每个小区的传输带宽消减系数，对每个服务小区对终端的最大调度带宽进行调度消减，以降低服务小区对终端的调度带宽。基站根据主小区的消减系数1、辅小区1的消减系数2和辅小区2的消减系数3分别对主小区、辅小区1和辅小区2的最大工作带宽(图4中灰色部分所示)进行调度消减，以降低主小区、辅小区1和辅小区2分别对终端进行调度的实际带宽(如图4中黑色部分所示)。
其次，对上述第二种传输带宽消减方式进行说明，图5为本申请实施例中终端上报一个所有服务小区共用的消减系数时对应的一个传输带宽消减示意图；如图5所示，针对每一次传输带宽消减，终端通过终端辅助控制信息消息仅上报一个消减系数4，该消减系数4为主小区、辅小区1和辅小区2共同对应的传输带宽消减系数，最终，基站根据终端上报的终端对应的小区组内所有服务小区共同对应的带消减系数4分别对主小区、辅小区1和辅小区2的最大工作带宽(图5中灰色部分所示)进行调度消减，以降低主小区、辅小区1和辅小区2分别对终端进行调度的实际带宽(如图5中黑色部分所示)。
最后，对上述第三种传输带宽消减方式进行说明，图6为本申请实施例中终端上报一个所有服务小区总传输带宽的消减系数时对应的一个传输带宽消减示意图；与上述第二种传输带宽消减方式的相似之处在于：终端上报的传输带宽消减系数的数目均是一个，如图6所示，终端通过终端辅助控制信息消息仅上报一个消减系数5，区别之处在于：该消减系数5对应小区组内所有服务小区的带宽总和，而不是小区组内所有服务小区共同对应的传输带宽消减系数，仅一步，基站根据消减系数5以及小区组内所有服务小区的带宽总和确定终端可以消减的总带宽，经一步，根据小区组内每一个服务小区的网络调度情况，将上述确定的终端可以消减的总带宽分配到各个小区如主小区、辅小区1和辅小区2，以对主小区、辅小区1和辅小区2的最大工作带宽(图6中灰色部分所示)进行调度消减，以降低主小区、辅小区1和辅小区2分别对终端进行调度的实际带宽(如图6中黑色部分所示)。
需要说明的是，本申请实施例中每一个传输带宽消减系数的范围均在0到1之间，包括0和1。
在本申请实施例中，通过扩展无线资源控制重配置消息中其他配置(OtherConfig)信息，以及对终端辅助控制信息消息进行扩展以指示基站对为终端提供服务的服务小区进行传输带宽消减，以实现基站对终端的最大调度带宽的消减，降低基站对终端的调度带宽，以降低终端的功率损耗，从而提升终端的续航能力。
第二种信息承载方式：传输带宽消减配置信息承载于无线资源控制重配置消息中的主小区配置(SpCellConfig)信息中，目标传输带宽消减系数承载于媒体访问控制层控制单元(MAC CE)中。
图7为本申请实施例提供的消减网络设备传输带宽的方法的另一个实施例示意图。
701、基站通过无线资源控制重配置消息中的主小区配置信息为终端进行传输带宽消减配置。
基站通过对无线资源控制配置消息中的主小区配置(SpCellConfig)信息进行扩展，以指示基站支持网络传输带宽消减，也可以理解为，指示对应的小区组(CellGroup)支持网络传输带宽消减。
具体来说，在无线资源控制重配置消息中主小区配置(SpCellConfig)信息中新增加传输带宽消减 配置信息，以用于指示基站支持网络传输带宽消减。需要说明的是，步骤701中其他描述与上述步骤301类似，步骤701中的其他描述可参阅上述步骤301中的相关描述，对此此处不再赘述。
702、终端通过媒体访问控制层控制单元通知基站对服务小区的带宽进行调度消减。
通过新增加媒体访问控制层控制单元(MAC CE)，以用于指示主小区(SpCell)终端期望的各载波对应的消减系数即目标带宽消减系数。需要说明的是，上述主小区(SpCell)可以是任一个小区组内的主小区，例如，上述图1b中所示的主小区组或者辅小区组，对此本申请不做具体限定。
具体来说，在终端需要降低功耗时，终端向基站发送上述用于指示主小区(SpCell)终端期望的各载波对应的消减系数的媒体访问控制层控制单元(MAC CE)，并在对应的媒体访问控制层控制单元(MAC CE)中上报终端对应的服务小区的传输带宽消减系数。
具体的，可以新增MAC CE 50和MAC CE 51用于终端向基站上报传输带宽消减系数。
一方面，MAC CE 50的结构定义如图8所示，MAC CE 50中包括：4个字节，分别简称字节1，字节2，字节3和字节4，每一个字节中存储两个传输带宽消减系数，每一个传输带宽消减系数的长度为4个比特，表示终端期望基站在对应的载波上调度的带宽不超过整个最大调度带宽的占比，如图8所示，字节1中的存储主小区以及辅小区1对应的传输带宽消减系数，字节2中存储辅小区2和3的传输带宽消减系数，字节3中存储辅小区4和5的传输带宽消减系数，字节4中存储辅小区6和7的传输带宽消减系数。
另一方面，MAC CE 51的结构定义如图9所示，MAC CE 51的结构与上述图8所示的MAC CE 50的结构类似，不同之处在于，MAC CE 51的结构中包括：16个字节，能存储32个小区对应的传输带宽消减系数，具体如图9所示，此处不再赘述。
