具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
应理解，本发明的技术方案可以应用于各种通信系统，例如：全球移动通讯(Global System of Mobile communication，GSM)系统、码分多址(Code Division Multiple Access，CDMA)系统、宽带码分多址(Wideband Code Division Multiple Access，WCDMA)系统、通用分组无线业务(General Packet Radio Service，GPRS)、长期演进(Long Term Evolution，LTE)系统、先进的长期演进(Advanced long term evolution，LTE-A)系统、通用移动通信系统(Universal Mobile Telecommunication System，UMTS)等。
还应理解，在本发明实施例中，用户设备(UE，User Equipment)包括但不限于移动台(MS，Mobile Station)、移动终端(Mobile Terminal)、移动电话(Mobile Telephone)、手机(handset)及便携设备(portable equipment)等，该用户设备可以经无线接入网(Radio Access Network，RAN)与一个或多个核心网进行通信，例如，用户设备可以是移动电话(或称为“蜂窝”电话)、具有无线通信功能的计算机等，用户设备还可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置。
在本发明实施例中，基站(例如，接入点)可以是指接入网中在空中接口上通过一个或多个扇区与无线终端通信的设备。基站可用于将收到的空中帧与IP分组进行相互转换，作为无线终端与接入网的其余部分之间的路由器，其中接入网的其余部分可包括网际协议(IP)网络。基站还可协调对空中接口的属性管理。例如，基站可以是GSM或CDMA中的 基站(Base Transceiver Station，BTS)，也可以是WCDMA中的基站(NodeB)，还可以是LTE中的演进型基站(NodeB或eNB或e-NodeB，evolutional Node B)，本发明并不限定。
本发明实施例涉及的网络架构中包括网络设备，以及至少一个终端；其中，所述网络设备可以为基站，所述终端为具有无线通信功能的移动设备，比如手机。
图1为本发明实施例提供的一种数据无线承载(Data Radio Bearer，DRB)映射方法流程示意图，该流程示出了网络侧的处理流程，包括以下步骤101至步骤102：
步骤101，网络设备确定DRB的映射方式；所述DRB的映射方式是指DRB是否允许映射到许可频段载波上和/或是否允许映射到非许可频段载波上。
其中，本发明实施例中所述DRB的映射方式包括但不限于以下两种：第一映射方式和第二映射方式。第一映射方式是指DRB仅允许映射到许可频段载波上；第二映射方式是指DRB既允许映射到许可频段载波上也允许映射到非许可频段载波上。
步骤102，所述网络设备根据确定出的DRB的映射方式，在指定的载波上发送所述DRB的业务数据。
在步骤101中，所述网络设备可根据DRB的服务质量(Quality of Service，QoS)特点和/或无线链路控制(Radio Link Control，RLC)传输模式，确定DRB的映射方式，所述网络设备也可遵循预先约定的DRB的映射方式，从而使得那些对业务质量有一定要求的业务数据(如在线视频、游戏等)不在非许可频段载波上发送，避免了非许可频段载波非连续性工作引起的业务延迟增大和时延抖动导致的业务质量降低，可以有效改善用户的业务体验。
优选地，所述网络设备在根据QoS特点确定DRB的映射方式时，可依据预先设定的QCI(QoS Class Identifier，QoS等级)与DRB映射方式的对应关系表。在标准协议中，定义了两种类型业务：保障比特速率(Guaranteed Bit Rate，GBR)和非保障比特速率(Non Guaranteed Bit Rate，GBR)，以及9种QoS等级，如表1所示。终端建立的每个传输业务的DRB都对应一个QoS等级。本发明实施例中，可预先针对这9种QoS等级设置对应的DRB映射方式，比如针对小于或等于5的QoS等级，设置对应的DRB映射方式为仅允许映射到授权许可频段载波上，这样，在网络设备进行DRB映射时，可根据DRB的QoS等级查询该对应关系表从而得到对应的DRB映射方式。
表1：QoS等级表
Figure PCTCN2015093238-appb-000001
优选地，所述网络设备在根据RLC传输模式确定DRB的映射方式时，或者预先约定DRB映射方式时，可遵循以下原则：若DRB的RLC模式为非确认模式(Unacknowledged Mode，UM)，则确定DRB仅允许映射到许可频段载波上，若DRB的RLC模式为确认模式(Acknowledged Mode，AM)，则确定DRB既允许映射到许可频段载波上也允许映射到非许可频段载波上。
AM模式指每个发送的RLC数据包都要得到接收端的确认后，才能发送后续数据包，如果某个数据包没有得到确认，发送端将进行重传，直到收到确认或达到最大重传次数为止。这种模式可以保证数据包的可靠传输。本实施例中，若DRB的RLC模式为AM模式，则允许该DRB映射到许可频段载波上和非许可频段载波上，可以用于传送对数据包丢失敏感的业务数据包。
UM模式指发送的RLC数据包不需要得到接收端的确认。这种传输模式一般不能保证数据包的可靠传输但可以较好地保证数据传输延时，适用于对数据包丢失不敏感但对传输延时敏感的业务。本实施例中，若DRB的RLC模式为UM模式，则仅允许该DRB映射到许可频段载波上，可以用于传送对数据包丢失不敏感但对传输延时敏感的业务数据包。
进一步地，步骤102之后，所述网络设备可将所述DRB的映射方式指示给建立了所述DRB的终端。具体地，所述网络设备可通过RRC(Radio Resource Control，无线资源控 制)信令将所述DRB的映射方式指示给建立了所述DRB的终端。
网络设备可通过多种方式在RRC信令中指示出DRB的映射方式，优选地，所述RRC信令中可包含第一DRB列表和第二DRB列表，所述第一DRB列表中的DRB既允许映射到许可频段载波上也允许映射到非许可频段载波上，所述第二DRB列表中的DRB不允许映射到非许可频段载波上。
进一步地，本发明实施例中，所述网络设备可在多种不同的时机确定DRB的映射方式，比如可在以下的一种或多种时机确定DRB的映射方式：
在DRB建立时，根据DRB的QoS特点和/或RLC传输模式，确定所建立的DRB的映射方式；
在DRB建立后，根据信号干扰情况和/或传输业务的接收质量，重新确定并配置所建立的DRB的映射方式；
所述网络设备作为切换目标网络设备接收源网络设备发送的切换终端的DRB映射方式信息后，重新确定并配置所述切换终端的DRB的映射方式。
本发明的上述实施例中，通过网络设备确定DRB的映射方式，并将映射方式指示给终端，根据确定出的DRB的映射方式，网络设备和终端在指定的载波上发送DRB的业务数据，从而实现了在许可频段资源上和/或非许可频段资源上传输数据。
图2为本发明实施例提供的另一种DRB映射方法流程示意图，该流程示出了终端侧的处理流程，包括以下步骤201至步骤202：
步骤201，终端确定DRB的映射方式；所述DRB的映射方式是指DRB是否允许映射到许可频段载波上和/或是否允许映射到非许可频段载波上。
其中，本发明实施例中所述DRB的映射方式包括但不限于以下两种：第一映射方式和第二映射方式。第一映射方式是指DRB仅允许映射到许可频段载波上；第二映射方式是指DRB既允许映射到许可频段载波上也允许映射到非许可频段载波上。
步骤202，所述终端根据所述DRB映射方式，在指定的载波上发送所述DRB的业务数据。
在步骤201中，终端可通过以下两种方式确定DRB的映射方式。
方式一：终端根据网络设备发送的指示信息，确定DRB的映射方式，该指示信息中指示出终端的DRB的映射方式；终端通过无线资源控制RRC信令接收该指示信息：RRC信令中包含第一DRB列表和第二DRB列表，所述第一DRB列表中的DRB既允许映射到许可频段载波上也允许映射到非许可频段载波上，所述第二DRB列表中的DRB不允许映射到非许可频段载波上。
方式二：终端遵循预先约定的DRB的映射方式，例如，预先约定了RLC模式为UM的DRB仅能映射到许可频段载波上，RLC模式为AM的DRB既能映射到许可频段载波也 能映射到非许可频段载波上，则终端遵循这一约定来确定DRB的映射方式。
本发明实施例中，所述终端可在多种不同的时机确定DRB的映射方式，比如可在以下的一种或多种时机确定DRB的映射方式：
在DRB建立时，终端接收网络设备发送的第一指示信息，根据第一指示信息确定DRB的映射方式，该第一指示信息中指示出终端的DRB的映射方式。
在DRB建立后，终端接收网络设备发送的第二指示信息，根据第二指示信息确定DRB的映射方式，该第二指示信息中指示出网络设备为终端重新配置的DRB的映射方式。
终端切换到目标网络设备后，接收目标网络设备发送的第三指示信息确定DRB的映射方式，该第三指示信息中指示出目标网络设备为终端重新配置的DRB的映射方式。
本发明的上述实施例中，通过终端确定DRB的映射方式，并根据所述DRB映射方式，在指定的载波上发送所述DRB的业务数据，从而实现了在许可频段资源上和/或非许可频段资源上传输数据。
进一步地，终端确定DRB的映射方式后，向网络设备发送携带有DRB的待传输数据量的BSR，具体可采用以下三种方式上报BSR。
方式一：终端将在不同类别载波上传输的上行DRB对应的逻辑信道映射到不同的逻辑信道组。
例如，逻辑信道0～3只能在许可频段载波上传输；逻辑信道4～9可以映射到许可频段载波或非许可频段载波上传输；那么，在将DRB映射到逻辑信道组时，可以将两类逻辑信道映射到不同的逻辑组，比如：逻辑信道0和1映射到逻辑信道组0；逻辑信道2和3映射到逻辑信道组1；逻辑信道4，6，7，8，9映射到逻辑信道组2；逻辑信道5映射到逻辑信道组3。
当网络设备接收到针对逻辑信道组0和1的BSR上报，就知道这些数据量只能在许可频段载波上传输；收到针对逻辑信道组2和3的BSR上报，就知道这些数据量可以在两类载波上传输。
方式二：终端上报两类BSR，一类只包含各逻辑信道组仅能在许可频段载波上传输的数据量；另一类包含各逻辑信道组可以在非许可频段载波或许可频段载波上传输的数据量。
例如，逻辑信道0～3只能在许可频段载波上传输；逻辑信道4～9可以映射到许可频段载波和非许可频段载波上传输，在划分逻辑信道组时：逻辑信道0和4，5映射到逻辑信道组0；逻辑信道1和6,7映射到逻辑信道组1；逻辑信道2和8映射到逻辑信道组2；逻辑信道3和9映射到逻辑信道组3。
在进行BSR上报时，终端上报两类BSR。其中，第一类BSR指示仅能在许可频段载波上传输的数据量：即逻辑信道组0中只包含逻辑信道0的数据量；逻辑信道组1中只包 含逻辑信道1的数据量；逻辑信道组2中只包含逻辑信道2的数据量；逻辑信道组3中只包含逻辑信道3的数据量。第二类BSR指示可以在非许可频段载波或许可频段载波上传输的数据量：即逻辑信道组0中只包含逻辑信道4,5的数据量；逻辑信道组1中只包含逻辑信道6,7的数据量；逻辑信道组2中只包含逻辑信道8的数据量；逻辑信道组3中只包含逻辑信道9的数据量。
进一步地，上述两类BSR可以利用媒体访问控制地址(Media Access Control Address，MAC)子头中的R比特进行区分，或者使用逻辑信道标识(logical channel identify，LCID)进行区分。
由此，网络设备可以根据BSR的类别，确定在两类载波上的待传数据量。
方式三：终端上报两类BSR，一类只包含各逻辑信道组仅能在许可频段载波上传输的数据量；另一类包含各逻辑信道组所有的待传输的数据量。
例如，逻辑信道0～3只能在许可频段载波上传输；逻辑信道4～9可以映射到许可频段载波和非许可频段载波上传输，在划分逻辑信道组时：逻辑信道0和4，5映射到逻辑信道组0；逻辑信道1和6，7映射到逻辑信道组1；逻辑信道2和8映射到逻辑信道组2；逻辑信道3和9映射到逻辑信道组3。
在进行BSR上报时，终端上报两类BSR。其中，第一类BSR指示各逻辑信道组仅能在许可频段载波上传输的数据量：即逻辑信道组0中只包含逻辑信道0的数据量；逻辑信道组1中只包含逻辑信道1的数据量；逻辑信道组2中只包含逻辑信道2的数据量；逻辑信道组3中只包含逻辑信道3的数据量。第二类BSR指示各逻辑信道组总的待传数据量：即逻辑信道组0中包含逻辑信道0，4，5的数据量；逻辑信道组1中只包含逻辑信道1，6，7的数据量；逻辑信道组2中只包含逻辑信道2，8的数据量；逻辑信道组3中只包含逻辑信道3，9的数据量。
两类BSR可以利用MAC子头中的R比特进行区分，或者使用LCID进行区分。
由此，网络设备可以根据BSR的类别，确定在两类载波上的待传数据量。
本发明实施例中，终端确定DRB的映射方式后，确定DRB对应的逻辑信道的优先级；终端根据该优先级为DRB对应的逻辑信道分配资源，具体包括以下三个步骤：
步骤一：终端根据传统逻辑信道优先级排队机制，确定各逻辑信道的资源分配先后顺序，并从第一个逻辑信道其依次分配资源；
步骤二：如果当前逻辑信道数据可以使用非许可频段载波资源传输，则优先为其分配非许可频段载波资源；如果非许可频段载波资源分配完毕，则继续为其分配许可频段载波资源，直到许可频段载波资源资源分配完毕或当前逻辑信道待传数据都分配到传输资源；如果当前逻辑信道数据只可以使用许可频段载波资源传输，则为其分配许可频段载波资源，直到传统载波资源资源分配完毕或当前逻辑信道待传数据都分配到传输资源；
步骤三：如果有资源未分配完毕，且还有逻辑信道未进行资源分配，返回步骤二继续为下一逻辑信道分配资源。
为了更清楚地理解本发明，下面结合几个具体实施例进行详细说明。
实施例一
本实施例中，网络部署了LTE-U载波，作为辅载波为终端提供无线资源。网络设备在DRB建立时，确定所建立的DRB的映射方式。
在DRB建立时，网络设备根据DRB的QoS特点和/或RLC传输模式，确定所建立的DRB的映射方式。例如，若一个DRB的QCI小于等于5，则确定该DRB不能映射到非许可频段载波上。网络设备通过专用RRC信令向终端发送指示信息，所述指示信息中包括所确定的DRB的具体映射方式。
终端收到网络设备发送的指示信息后，进行DBR的建立。终端根据指示信息将QCI为1～5的DBR映射到许可频段载波上；而对于QCI为6～9的DBR，则不受限制，根据无线资源的空闲状况，既可映射到许可频段载波的物理信道上也可映射到非许可频段载波的物理信道上。
实施例二
本实施例中，网络设备部署了非许可频段LTE-U载波，作为辅载波为终端提供无线资源。网络设备在DRB建立后，根据信号干扰情况和/或传输业务的接收质量，重新确定并配置所建立的DRB的映射方式。
网络设备在DRB建立时，配置QCI为1～5的DRB仅能映射到许可频段载波上，对于QCI为6～9数据承载，则既可映射到许可频段载波上也可映射到非许可频段载波上。
在DRB建立后，网络设备基于信号干扰情况及特定业务的接收质量，可以在某个时刻更改DRB建立时已有的配置。例如，网络设备对QCI为6或7的DRB的配置进行修改，限定QCI为6或7的DRB不能映射到非许可频段载波上。网络设备重新确定并配置所建立的DRB的映射方式后，通过专用RRC信令向终端发送指示信息，所述指示信息中包括重新确定并配置的DRB的具体映射方式。
终端接收到指示信息后，修改重新配置的DRB的映射方式，例如，对于QCI为6或7的DRB，终端只将其映射到许可频段载波上。
实施例三
网络部署了非许可频段LTE-U载波，作为辅载波为用户提供无线资源。网络设备作为切换目标网络设备接收源网络设备发送的切换终端的DRB映射方式信息，重新确定并配置所述切换终端的DRB的映射方式。
终端在源网络设备接受服务时，源网络设备为终端的DRB配置了映射方式，其中QCI为7的DRB不能在非许可频段载波上发送。终端从源网络设备切换到目标网络设备时， 原有的DRB映射方式通过网络设备之间的接口从源网络设备发送到目标网络设备。终端切换目标网络设备后，目标网络设备决定改变原有的DRB映射方式，允许QCI为7的DRB既可映射到许可频段载波也映射到非许可频段载波上。
目标网络设备重新配置DRB的映射方式后，通过专用RRC信令向终端发送指示信息，所述指示信息中包括重新配置的DRB的具体映射方式。终端接收到指示信息后，修改重新配置的DRB的映射方式。
实施例四
本实施例中，网络设备部署了非许可频段LTE-U载波，作为辅载波为用户提供无线资源。网络设备和终端遵循预先约定的DRB的映射方式。
具体地，网络设备遵循预先约定的DRB的映射方式，例如，预先约定了RLC模式为UM的DRB仅能映射到许可频段载波上，RLC模式为AM的DRB既能映射到许可频段载波也能映射到非许可频段载波上，则网络设备和终端分别遵循这一约定来确定DRB的映射方式。
