Description

无线承载建立方法和设备 技术领域
本发明实施例涉及通信技术领域，尤其涉及一种无线承载建立方法和设备。
背景技术
在无线通信网络中，用户设备(User Equipment，简称：UE)与基站之间的接口属于空中接口，简称为空口。该空中接口的协议栈中分为控制面(Control Plane，简称：CP)和用户面(User Plane，简称：UP)。UE和基站之间通过建立信令无线承载(Sginaling Radio Bearer，简称：SRB)来完成控制面的连接建立，并在控制面的连接建立的基础上通过建立数据无线承载(Data Radio Bearer，简称：DRB)来完成用户面的连接建立。一个SRB可以对应多个DRB，一个DRB对应一种业务数据(例如视频、网页浏览等，但不包括广播业务)。SRB和DRB可以通过逻辑信道、传输信道和物理信道来分别实现信令和数据在无线链路控制层、媒体访问控制层以及物理层的信息传递。
然而，现有技术中，由于在UE所接入的同一个小区中，SRB和各个业务所分别对应的各个DRB复用在同一个传输信道和同一个物理信道上传输，若SRB或一个或部分DRB的配置发生了变化，由于每个DRB的Qos要求不同，那么也需要同时重新配置该传输信道和物理信道，可能会导致UE和基站之间所有业务数据中断，降低了用户体验。

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。
本发明的技术方案，可以应用于各种无线通信系统，例如：全球移动通信系统(Global System for Mobile Communications，简称：GSM)、通用分组无线业务(General Packet Radio Service，简称：GPRS)系统、码分多址(Code Division Multiple Access，简称：CDMA)系统、CDMA2000系统、宽带码分多址(Wideband Code Division Multiple Access，简称：WCDMA)系统、长期演进(Long Term Evolution，简称：LTE)系统或全球微波接入互操作性(World Interoperability for Microwave Access，简称：WiMAX)系统等。
基站，可以是GSM系统、GPRS系统或CDMA系统中的基站控制器(Base Station Controller，简称：BSC)，还可以是LTE系统中的演进型基站(Evolved NodeB，简称：eNB)，还可以是WiMAX网络中的接入服务网络的基站(Access Service Network Base Station，简称：ASN BS)等网元。UE可以是手机或平板电脑等设备。
在此对逻辑信道、传输信道和物理信道进行说明。
逻辑信道是为无线承载(即SRB和DRB，其中，SRB为传输控制数据的无线承载，DRB为传输业务数据的无线承载)提供数据传输业务，逻辑信道可以分为控制逻辑信道和业务逻辑信道，控制逻辑信道用于承载控制数据(即SRB上的控制信令)，业务逻辑信道用于承载业务数据(即DRB上的业务数据)。本发明各实施例中的业务数据包括短信、语音以及各种多媒体业务等，但不包括广播业务；也就是本实施例中的业务数据是针对一个UE而言的，而广播业务是针对一组UE(即多个UE)而言的。
传输信道用于定义数据在空口上传输的方式和特性(例如传输速率、误码率、时延等)。物理信道定义数据在空口上传输的物理资源，具体可以包括载频、扰码、信道化码(可选的)、开始和结束时间(有一段持续时间) 等。
逻辑信道用于定义传输数据的类型，因此，基站与UE之间传输的数据(控制信令或业务数据)先承载在相应的逻辑信道上，承载在逻辑信道上的数据可能是独立成块的数据流，也可能是夹杂在一起但是有确定起始位的数据流。承载有数据的逻辑信道将复用到传输信道上，即对承载在逻辑信道中数据进行特定处理并加上传输格式等指示信息，然后将承载有数据的传输信道复用到物理信道上，即将承载在传输信道中的数据按照该数据所属的UE和该数据的功用确定其载频、扰码、扩频码、开始和结束时间进行相关的操作，并在最终调制为模拟射频信号发射出去。
图1为现有技术中逻辑信道、传输信道、物理信道的映射关系图，如图1所示，SRB所占用的逻辑信道包括公共控制信道(英文：Common Control Channel，简称：CCCH)和专用控制信道(英文：Dedicated Control Channel，简称：DCCH)，DRB所占用的逻辑信道包括专用业务信道(英文：Dedicated Traffic Channel，简称：DTCH)，若存在多种业务时，例如业务1和业务2，业务1对应的DRB所占用的逻辑信道为DTCH1，业务2对应的DRB所占用的逻辑信道为DTCH2。在逻辑信道复用到传输信道时，CCCH、DCCH、DTCH1和DTCH2复用到同一传输信道，即共享信道(英文：Share Channel，简称：SCH)，在上行链路中，CCCH、DCCH、DTCH1和DTCH2复用到同一上行共享信道(英文：Uplink-Share Channel，简称：UL-SCH)，在下行链路中，CCCH、DCCH、DTCH1和DTCH2复用到同一下行共享信道(英文：Downlink-Share Channel，简称：DL-SCH)。在传输信道复用到物理信道时，SCH复用于物理共享信道(英文：Physical Share Channel，简称：PSCH)，在上行链路中，UL-SCH复用到物理上行共享信道(英文：Uplink Physical Share Channel，简称：PUSCH)，在下行链路中，DL-SCH复用到物理下行共享信道(英文：Downlink Physical Share Channel，简称：PDSCH)。
因此，各个业务所对应的各个DRB所占用的逻辑信道通常是不同的，而各个DRB所占用的逻辑信道复用到所占用的传输信道通常是相同的；例如，传输信道的传输速率、误码率和时延都是相同的。另外，各个DRB复用到的所占用的传输信道再次复用所占用的物理信道通常也是相同的；例如，物理信道的载频、扰码、信道化码(可选的)、开始和结束时间(有一段持续时 间)等都是相同的。各个DRB占用传输信道的方式可以为各个DRB的数据传输通过调度的方式复用在传输信道；各个DRB占用物理信道的方式可以为各个DRB的数据传输通过调度的方式复用在物理信道上。因而，当其中一个或部分DRB的配置发生变化，由于可能不能同时满足各个DRB的QoS要求，所有的DRB都可能需要重新配置，从而导致用户体验可能得不到保证。
图2为本发明无线承载建立方法实施例一的流程图，如图2所示，本实施例的方法可以包括：
S101、基站根据SRB的配置参数，与用户设备UE建立所述SRB，所述SRB的配置参数用于指示所述SRB所占用的传输信道和物理信道。
S102、基站根据承载N个业务的N个DRB的配置参数，与所述UE建立所述N个DRB，所述N为大于或等于2的整数，所述N个DRB的配置参数用于指示所述N个DRB所占用的传输信道和物理信道。
本实施例中，基站根据SRB的配置参数，与UE建立SRB，该UE的SRB位于该基站所控制的小区，即该UE与该基站控制的小区建立该SRB。基站也可以根据承载N个业务的N个DRB的配置参数，与UE建立N个DRB，该UE的N个DRB位于该基站所控制的小区，即该UE与该基站控制的小区建立该N个DRB，该UE可以与该基站控制的至少一个小区建立该N个DRB，该UE可以与该一个小区建立至少一个DRB。该SRB与该N个DRB可以同时位于该基站所控制的同一个小区，也可以分别位于该基站所控制的不同小区，该N个DRB可以同时位于该基站所控制的同一个小区，也可以分别位于该基站所控制的不同小区。
不论该N个DRB位于该基站所控制的同一小区还是不同小区，该N个DRB中存在M个DRB所占用的传输信道不同，例如：该M个DRB的传输速率、误码率和时延中至少一个是不同的；该N个DRB中存在M个DRB所占用的物理信道不同，例如该M个DRB所占用的时隙不同和所占用的频率中至少一个是不同的。由于该N个DRB中存在M个DRB所占用的传输信道不同，物理信道也不同，从而实现了DRB分离，不会造成N个DRB中有一个或部分DRB改变而造成所有的DRB的配置都发生变化而使得用户体验降低。各个DRB的数据传输在各自的传输信道和物理信道上，可以满足各自QoS要求。以N为3举例来说：这3个DRB中存在两个DRB所占用的传 输信道不同以及所占用的物理信道不同，即该3个DRB中有1个DRB与另外两个DRB所占用的传输信道不同以及所占用的物理信道不同；或者，该3个DRB中存在3个DRB所占用的传输信道不同以及所占用的物理信道不同，即该3个DRB中各个DRB所占用的传输信道不同以及所占用的物理信道不同。
不论该SRB与该N个DRB中至少一个DRB位于该基站所控制的同一小区还是不同小区，所述SRB所占用的传输信道和所述N个DRB中至少一个DRB所占用的传输信道不同，例如：该SRB和该N个DRB中至少一个DRB的，传输速率、误码率和时延中至少一个是不同的；所述DRB所占用的物理信道和所述N个DRB中至少一个DRB所占用的物理信道不同，例如：SRB和N个DRB中至少一个DRB，所占用的时隙和所占用的频率中至少一个是不同的。由于该UE的SRB和DRB所占用的传输信道不同，物理信道也不同，从而实现了SRB和DRB分离，SRB的配置改变不会影响到DRB的配置，不会导致在SRB配置改变时由于影响到DRB的配置改变而造成的用户体验降低。SRB和DRB的数据传输在各自的传输信道和物理信道上，可以满足各自QoS要求。以N为3举例来说：该SRB可以与这3个DRB中的一个DRB所占用的传输信道不同以及所占用的物理信道不同，即该SRB与该3个DRB中的两个DRB所占用的传输信道相同以及所占用的物理信道相同，而该SRB与该3个DRB中的另外一个DRB所占用的传输信道不同以及所述占用的物理信道不同；或者，该SRB与该3个DRB中的两个DRB所占用的传输信道不同以及所占用的物理信道不相同，而该SRB与该3个DRB中的另外一个DRB所占用的传输信道相同以及所述占用的物理信道相同；或者，该SRB与该3个DRB中的各个DRB所占用的传输信道不同以及所占用的物理信道不相同。
例如：如果UE需要建立2个业务，分别为语音和网页浏览，则建立DRB1和DRB2。DRB1和DRB2所占用的传输信道不同，例如：为DRB1和DRB2分配的传输速率不同，或者，为DRB1和DRB2分配的误码率不同，或者，为DRB1和DRB2分配的时延不同。DRB1和DRB2所占用的物理信道不同，例如：为DRB1和DRB2分配的频率不同。
因此，当该UE的一个或部分DRB的配置发生变化时，只需要重新配置 该一个或部分DRB所占用的传输信道和物理信道即可，可以不需要重新配置该UE的其它DRB所占用的传输信道和物理信道；这样DRB之间不会互相影响，也就不会导致UE与基站之间的所有业务数据中断以及通信连接掉话，从而减少了时延，提高了网络吞吐量。而且各个DRB具有不同的QoS要求，因此，将各个DRB进行分离可以更加灵活地保证各个DRB的QoS要求，而且不会相互影响，提高了UP连接上数据传输的灵活性和网络吞吐量。
图3为本发明实施例提供的空口协议栈的第一种示意图，如图3所示，以两个DRB(即DRB1和DRB2)为例进行说明，SRB、DRB1、DRB2分别占用层(Layer，简称：L)2和L1中不同的信道，也就是SRB、DRB1、DRB2分别占用不同的传输信道和物理信道上，表示UE与无线接入网(英文：Radio Access Network，简称：RAN)(例如基站)之间的各个DRB配置在不同的传输信道和物理信道上，而且，该SRB和各个DRB配置在不同的传输信道和物理信道上。SRB承载无线信令数据，无线信令数据包括无线资源控制协议(英文：Radio Resource Control，简称：RRC)信令以及NAS信令等L3信令(包括与DRB相关的信令)，DRB承载无线业务数据。其中，L2指的是分组数据汇聚协议(英文：Packet Data Convergence Protocol，简称：PDCP)/无线链路控制(英文：Radio Link Control，简称：RLC)/MAC，L1是指物理层(英文：Physical Layer)。
可选地，与所述UE分别建立所述M个DRB的小区可以是同一个小区，也可以是同一基站控制的不同小区，或者，与所述UE建立所述M个DRB的M个小区中可以有一部分小区是同一个小区。与所述UE建立SRB的小区和与所述UE建立N个DRB中至少一个DRB的小区可以是同一个小区，也可以是同一基站控制的不同小区。
可选地，与所述UE分别建立所述M个DRB的小区工作的无线接入技术(英文：Radio Access Technology，简称：RAT)相同，例如UE与同系统中的不同小区分别建立该M个DRB，该UE的这M个DRB分别配置在不同的传输信道和物理信道上。与所述UE建立SRB的小区和与所述UE建立N个DRB中至少一个DRB的小区的RAT相同，例如UE与同系统中的不同小区分别建立该SRB和该至少一个DRB，该UE的SRB与该至少一个DRB配置在不同的传输信道和物理信道上。
如图4所示，与UE建立SRB的小区、与UE建立DRB1的小区、与UE建立DRB2的小区的RAT相同；其中，与UE建立SRB的小区，和，与UE建立DRB1的小区为同一小区。但是与UE建立SRB的小区，和，与UE建立DRB2的小区不是同一小区。
可选地，与所述UE分别建立所述M个DRB的M个小区的RAT不同，例如UE与不同系统中的小区分别建立该M个DRB，该UE的这M个DRB分别配置在不同的传输信道和物理信道上。与所述UE建立SRB的小区和与所述UE建立N个DRB中至少一个DRB的小区的RAT不同，例如UE与不同系统中的小区分别建立该SRB和该至少一个DRB，该UE的SRB与该至少一个DRB配置在不同的传输信道和物理信道上。
如图5所示，与UE建立SRB的小区，和，与UE建立DRB1的小区的RAT相同，RAT为RAT1；而与UE建立SRB的小区，和，与UE建立DRB2的小区的RAT不同，与UE建立DRB2的小区的RAT为RAT2。
本发明实施例提供的无线承载建立方法，通过基站和UE在建立无线承载时，UE的M个DRB所占用的传输信道所占用的传输信道不同以及所占用的物理信道也不同，从而实现了同一UE的DRB分离，在UE所入的同一小区中，一个或部分DRB发生变化时，所有DRB的配置不会同时中断变化，不会导致UE与基站之间的所有业务数据中断以及通信连接掉话，提高了用户体验，同时减少了时延，增加了网络吞吐量，还提高了UP连接上数据传输的灵活性。
图6为本发明无线承载建立方法实施例二的流程图，如图6所示，本实施例的方法可以包括：
S201、UE根据SRB的配置参数，与基站建立SRB，所述SRB的配置参数用于指示所述SRB所占用的传输信道和物理信道。
S202、所述UE根据承载N个业务的N个DRB的配置参数，与所述基站建立所述N个DRB，所述N为大于或等于2的整数，所述N个DRB的配置参数用于指示所述N个DRB所占用的传输信道和物理信道。
本实施例中，本实施例中，UE根据SRB的配置参数，与基站建立SRB，该UE的SRB位于该基站所控制的小区，即该UE与该基站控制的小区建立该SRB。UE也可以根据承载N个业务的N个DRB的配置参数，与基站建 立N个DRB，该UE的DRB位于该基站所控制的小区，即该UE与该基站控制的小区建立N个DRB。该SRB与该N个DRB可以位于该基站所控制的同一个小区，也可以位于该基站所控制的不同小区。
不论该N个DRB位于该基站所控制的同一小区还是不同小区，该N个DRB中存在M个DRB所占用的传输信道不同，例如：该M个DRB的传输速率、误码率和时延中至少一个是不同的；该N个DRB中存在M个DRB所占用的物理信道不同，例如该M个DRB所占用的时隙不同和所占用的频率中至少一个是不同的。由于该N个DRB中存在M个DRB所占用的传输信道不同，物理信道也不同，从而实现了DRB分离。各个DRB的数据传输在各自的传输信道和物理信道上，可以满足各自QoS要求。以N为3举例来说：这3个DRB中存在两个DRB所占用的传输信道不同以及所占用的物理信道不同，即该3个DRB中有1个DRB与另外两个DRB所占用的传输信道不同以及所占用的物理信道不同；或者，该3个DRB中存在3个DRB所占用的传输信道不同以及所占用的物理信道不同，即该3个DRB中各个DRB所占用的传输信道不同以及所占用的物理信道不同。
不论该SRB与该N个DRB中至少一个DRB位于该基站所控制的同一小区还是不同小区，所述SRB所占用的传输信道和所述N个DRB中至少一个DRB所占用的传输信道不同，例如：该SRB和该N个DRB中至少一个DRB的，传输速率、误码率和时延中至少一个是不同的；所述DRB所占用的物理信道和所述N个DRB中至少一个DRB所占用的物理信道不同，例如：SRB和N个DRB中至少一个DRB，所占用的时隙和所占用的频率中至少一个是不同的。由于该UE的SRB和DRB所占用的传输信道不同，物理信道也不同，从而实现了SRB和DRB分离。SRB和DRB的数据传输在各自的传输信道和物理信道上，可以满足各自QoS要求。以N为3举例来说：该SRB可以与这3个DRB中的一个DRB所占用的传输信道不同以及所占用的物理信道不同，即该SRB与该3个DRB中的两个DRB所占用的传输信道相同以及所占用的物理信道相同，而该SRB与该3个DRB中的另外一个DRB所占用的传输信道不同以及所述占用的物理信道不同；或者，该SRB与该3个DRB中的两个DRB所占用的传输信道不同以及所占用的物理信道不相同，而该SRB与该3个DRB中的另外一个DRB所占用的传输信道相同以及所述 占用的物理信道相同；或者，该SRB与该3个DRB中的各个DRB所占用的传输信道不同以及所占用的物理信道不相同。
因此，当该UE的一个或部分DRB的配置发生变化时，只需要重新配置该一个或部分DRB所占用的传输信道和物理信道即可，可以不需要重新配置该UE的其它DRB所占用的传输信道和物理信道；这样DRB之间不会互相影响，也就不会导致UE与基站之间的所有业务数据中断以及通信连接掉话，从而减少了时延，提高了网络吞吐量。而且各个DRB具有不同的QoS要求，因此，将各个DRB进行分离可以更加灵活地保证各个DRB的QoS要求，而且不会相互影响，提高了UP连接上数据传输的灵活性和网络吞吐量。
可选地，与所述UE分别建立所述M个DRB的小区可以是同一个小区，也可以是同一基站控制的不同小区，或者，与所述UE建立所述M个DRB的M个小区中可以有一部分小区是同一个小区。与所述UE建立SRB的小区和与所述UE建立N个DRB中至少一个DRB的小区可以是同一个小区，也可以是同一基站控制的不同小区。
可选地，与所述UE分别建立所述M个DRB的小区工作的RAT相同，如图4所示，详细参见本发明方法实施一中的相关记载。
可选地，与所述UE分别建立所述M个DRB的M个小区的RAT不同，如图5所示，详细参见本发明方法实施例一中的相关记载。
本发明实施例提供的无线承载建立方法，UE和基站在建立无线承载时，UE的M个DRB所占用的传输信道不同以及所占用的物理信道也不同，从而实现了同一UE的DRB分离，在UE所入的同一小区中，一个或部分DRB发生变化时，所有DRB的配置不会同时变化，不会导致UE与基站之间的所有业务数据中断以及通信连接掉话，提高了用户体验，同时减少了时延，增加了网络吞吐量，还提高了UP连接上数据传输的灵活性。
图7为本发明无线承载建立方法实施例三的流程图，如图7所示，本实施例的方法包括：
S301、基站向UE发送SRB的配置参数和承载N个业务的N个DRB的配置参数。
S302、所述UE接收所述基站发送的所述SRB的配置参数和所述N个DRB的配置参数。
S303、所述基站与所述UE根据所述SRB的配置参数和所述N个DRB的配置参数，建立所述SRB和所述N个DRB。
本实施例中，基站可以通过UE的随机接入过程，确定该UE的SRB的配置参数，以建立SRB，并且当UE需要进行业务时，UE与核心网设备会进行业务协商过程，业务协商过程完成后，核心网设备会通知该基站建立该UE的承载N个业务的N个DRB，然后该基站再确定该N个DRB的配置参数，例如：核心网设备会向基站发送无线接入承载指示信息，该无线接入承载指示信息可以包括：建立该UE的无线接入承载的速率、时延、误码率等业务QoS信息，基站根据核心网设备发送的无线接入承载指示信息、N个DRB中M个DRB所占用的传输信道不同以及所占用的物理信道不同，来确定该UE的N个DRB的配置参数，以建立N个DRB。因此，本实施例中，基站所确定的SRB的配置参数用于指示该SRB所占用传输信道和物理信道，进一步地，SRB的配置参数还用于指示该SRB所占用的逻辑信道；基站所确定的N个DRB的配置参数中每个DRB的配置参数用于指示该DRB所占用的传输信道和物理信道，进一步地，每个DRB的配置参数还用于指示该DBR所占用的逻辑信道；需要说明的是，N个DRB中各个DRB所占用的逻辑信道不同，N个DRB中M个DRB所占用的传输信道不同以及所占用的物理信道不同，由于基站将N个DRB中M个DRB分别配置在不同的传输信道和物理信道上，那么UE的DRB实现了分离。
可选地，若基站确定SRB与该N个DRB位于同一小区(例如第一小区)，则由基站所控制的第一小区确定该UE的SRB的配置参数和N个DRB的配置参数。从而UE所建立的SRB和N个DRB位于同一小区。
可选地，若基站确定该SRB和N个DRB位于不同小区，例如：该SRB位于基站控制的第一小区，DRB1位于该基站所控制的第二小区，DRB2位于基站所控制的第三小区，在第一小区确定该UE的SRB的配置参数后，该第一小区判断DRB1需要位于该基站控制的第二小区以及DRB2需要位于该基站控制的第三小区，则第一小区再向第二小区发送UE的DRB1建立请求以及向第三小区发送DRB2建立请求，第二小区根据第一小区发送的UE的DRB1建立请求确定该UE的DRB1的配置参数，第三小区根据第一小区发送的UE的DRB2建立请求确定该UE的DR2的配置参数。例如：第一小区会 将从核心网设备接收的无线接入承载指示信息发送给第二小区和第三小区，该无线接入承载指示信息可以包括：建立该UE的DRB承载的速率、时延、误码率等QoS信息，第二小区再根据该无线接入承载指示信息确定UE的DRB1的配置参数，第二小区再将该UE的DRB1的配置参数包括在UE的DRB1建立响应中发送给第一小区，第一小区再从UE的DRB1建立响应中获取该UE的DRB2的配置参数，第三小区再根据该无线接入承载指示信息确定UE的DRB2的配置参数，第三小区再将该UE的DRB2的配置参数包括在UE的DRB2建立响应中发送给第一小区，第一小区再从UE的DRB2建立响应中获取该UE的DRB2的配置参数。从而UE所建立的SRB1位于第一小区，UE所建立的DRB1位于第二小区，UE所建立的DRB2位于第三小区。
本实施例中，基站在确定UE的SRB的配置参数和N个DRB的配置参数之后，基站可以根据UE的SRB的配置参数和N个DRB的配置参数生成无线资源配置消息，该无线资源配置消息包括所述SRB的配置参数和所述N个DRB的配置参数，然后基站通过公共连接向UE发送无线资源配置消息，从而使得UE接收到无线资源配置消息后，获取无线资源配置消息中的SRB的配置参数和N个DRB的配置参数，然后UE根据SRB的配置参数和N个DRB的配置参数，与基站建立SRB和N个DRB，基站也根据发送给该UE的SRB的配置参数和N个DRB的配置参数，与该建立SRB和N个DRB。从而UE建立的N个DRB中M个DBR占用在不同的传输信道上，而且UE建立的N个DRB中M个DRB占用在不同的物理信道上，因此，UE的DRB实现了分离。
下面对UE的SRB的配置参数和N个DRB的配置参数进行举例说明，如下所示为无线资源配置消息中指示UE的SRB的配置参数和N个DRB的配置参数的信元。mac-MainConfig for SRB是配置SRB的传输信道参数，mac-MainConfig for DRB是配置DRB的传输信道参数，PhysicalconfigDedicated for SRB是配置SRB的物理信道参数，PhysicalconfigDedicated for DRB是配置DRB的物理信道参数。其它部分与现有技术中的一致，此处不再赘述。

本实施例提供的无线承载建立方法，基站和UE在建立无线承载时，UE的N个DRB中存在至少两个DRB所占用的传输信道不同以及所占用的传输信道不同，从而实现了同一UE的DRB分离，在UE所入的同一小区中，一个或部分DRB发生变化时，所有DRB的配置不会同时变化，不会导致UE与基站之间的所有业务数据中断以及通信连接掉话，提高了用户体验，同时减少了时延，增加了网络吞吐量，还提高了UP连接上数据传输的灵活性。
图8为本发明无线承载建立方法实施例四的流程图，如图8所示，本实施例的方法包括：
S401、基站向UE发送SRB的配置参数。
S402、所述UE接收所述基站发送的所述SRB的配置参数。
S403、所述基站与所述UE根据所述SRB的配置参数，建立所述SRB。
本实施例中，UE可以通过随机接入过程建立该UE的SRB，基站通过UE的随机接入过程确定该UE的SRB的配置参数，该SRB的配置参数用于指示所述SRB所占用的传输信道和物理信道，进一步地，可以指示所述SRB所占用的逻辑信道。然后基站可以将确定好的SRB的配置参数通过无线资源配置消息发送给UE，UE可以根据SRB的配置参数与基站建立SRB。
S404、所述基站通过SRB向所述UE发送承载N个业务的N个DRB的配置参数。
S405、所述UE通过所述SRB接收所述基站发送的所述N个DRB的配置参数。
S406、所述基站与所述UE根据所述N个DRB的配置参数，建立所述N个DRB。
当UE需要进行业务时，UE与核心网设备会进行业务协商过程，业务协商过程完成后，核心网设备会通知基站建立该UE的承载N个业务的N个DRB，然后基站再确定该N个DRB的配置参数，例如：核心网设备会向基站发送无线接入承载指示信息，该无线接入承载指示信息可以包括：建立该UE的DRB承载的速率、时延、误码率等业务QoS信息，基站根据核心网设 备发送的无线接入承载指示信息、N个DRB中M个DRB所占用的传输信道不同以及所占用的物理信道不同，来确定该UE的N个DRB的配置参数，以建立N个DRB，本实施例中，基站所确定的N个DRB的配置参数用于指示该N个DRB所占用的传输信道和物理信道，进一步地还可以指示该N个DRB所占用的逻辑信道，基站可以将该N个DRB的配置参数携带在另一无线资源配置消息并通过已建立的SRB发送给该UE，相应地，UE可以通过该UE的SRB接收基站发送的N个DRB的配置参数。然后基站与UE可以根据该N个DRB的配置参数，建立N个DRB。
需要说明的是，N个DRB中的上述M个DRB可以位于该基站控制的同一个小区或者不同小区，该UE的SRB与该UE的DRB可以位于该基站控制的同一个小区或者不同小区，具体地，可以参见本发明上述方法实施例三中的相关记载，此处不再赘述。
本实施例提供的无线承载建立方法，基站和UE在建立无线承载时，UE的N个DRB中存在至少两个DRB所占用的传输信道不同以及所占用的传输信道不同，从而实现了同一UE的DRB分离，在UE所入的同一小区中，一个或部分DRB发生变化时，所有DRB的配置不会同时变化，不会导致UE与基站之间的所有业务数据中断以及通信连接掉话，提高了用户体验，同时减少了时延，增加了网络吞吐量，还提高了UP连接上数据传输的灵活性。
图9为本发明无线承载建立方法实施例五的流程图，如图9所示，本实施例在本发明方法实施例一至四任一实施例的基础上，进一步地，在所述基站根据N个DRB的配置参数，与所述UE建立所述N个DRB之后，本实施例的方法还可以包括：
S501、当所述UE需要在目标小区传输业务数据时，所述基站通过所述SRB向所述UE发送第一建立命令，所述第一建立命令包括所述UE与所述目标小区建立DRB的配置参数。
本实施例中，由于UE的至少两个DRB所占用的传输信道不同，而且物理信道也不同，因此，基站可以将UE的K个DRB重新建立在目标小区中，该目标小区为该K个DRB待切换到的小区。具体过程如下所述。
当该UE需要在目标小区传输业务数据时，即该UE需要与目标小区建立K个DRB，则基站获取该UE与该目标小区建立DRB的配置参数，该UE与 该目标小区建立DRB的配置参数用于指示该UE与该目标小区建立的K个DRB所占用的传输信道和物理信道，进一步地还指示该UE与该目标小区建立的DRB所占用的逻辑信道，并且该UE与该目标小区建立的K个DRB与所述N个DRB中除K个DRB之外的至少一个DRB所占用的传输信道不同以及所占用的物理信道不同。若该目标小区为该基站控制的一个小区，则该基站可以确定该UE与该目标小区建立DRB的配置参数。若该目标小区为另一基站控制的一个小区，则该基站向控制该目标小区的基站请求获取该UE与该目标小区建立DRB的配置参数。然后该基站将UE与该目标小区建立DRB的配置参数携带在第一建立命令中通过所述SRB发送给所述UE。
S502、所述UE通过所述SRB接收所述基站发送的第一建立命令，所述第一建立命令包括所述UE与目标小区建立DRB的配置参数。
S503、所述UE根据所述第一建立命令，与所述目标小区建立K个DRB。
本实施例中，所述UE通过与所述基站建立的所述SRB接收所述基站发送的第一建立命令，该UE从第一建立命令中获取所述UE与所述目标小区建立DRB的配置参数，然后UE根据所述UE与所述目标小区建立DRB的配置参数，与目标小区建立K个DRB。若目标小区为所述基站控制的一个小区，则所述UE与所述基站根据所述UE与目标小区建立DRB的配置参数，建立新的K个DRB。若目标小区为另一基站控制的一个小区，则所述UE与该另一基站根据所述UE与目标小区建立DRB的配置参数，建立新的K个DRB。
在所述基站确定UE与目标小区建立DRB后，基站可以释放N个DRB的其中K个DRB在源小区中占用的资源，该源小区为所述UE在与目标小区建立DRB之前该UE的进行相同业务的K个DRB所位于的小区。
本发明实施例提供的无线承载建立方法，通过当所述基站确定所述UE需要在目标小区传输业务数据时，所述基站通过所述SRB向所述UE发送第一建立命令，所述第一建立命令包括所述UE与所述目标小区建立DRB的配置参数；所述UE根据所述第一建立命令，与所述目标小区建立至少一个DRB。从而可以实现UE的至少一个DRB可以单独重新建立。
图10为本发明无线承载建立方法实施例六的流程图，如图10所示，本实施例在本发明方法实施例一至四任一实施例的基础上，进一步地，在所述基站根据SRB的配置参数，与所述UE建立所述SRB之后，本实施例的方法 还可以包括：
S601、当所述UE需要在目标小区传输控制数据时，所述基站通过所述SRB向所述UE发送第二建立命令，所述第二建立命令包括所述UE与所述目标小区建立SRB的配置参数。
本实施例中，由于UE的SRB和N个DRB中至少一个DRB所占用的传输信道不同，而且物理信道也不同，因此，基站可以将UE的SRB单独重新建立在目标小区中，该目标小区为该SRB待切换到的小区。具体过程如下所述。

在所述基站确定UE与目标小区建立SRB后，基站可以释放SRB在源小区中占用的资源，该源小区为所述UE在与目标小区建立SRB之前该UE的SRB所位于的小区。
