具体实施方式
以5G通信系统为例，由于5G没有自己的核心网，没有高层协议栈，一种实现方案是采用LTE-5G双链接(DC，dual connectivity)技术来实现5G系统的通信功能。LTE-5G-DC是指用户设备(User Equipment，UE)通过长期演进(Long Term Evolution，LTE)系统接入，控制面(Control Plane，CP)保留在LTE系统，之后用户面(User Plane,UP)同时利用LTE空口和5G基站的空口来传输数据，即用户面锚在LTE分组数据汇聚协议(Packet Data  Convergence Protocol，PDCP)层进行数据包粒度或者承载粒度的分流。相应的，LTE-5G-DC场景下的物理组网可以采用图1或图2所示的架构，其中移动管理实体(Mobile Management Entity，MME)、服务网关(Serving Gate Way，SGW)为LTE的核心网的网元。在本申请实施例中将5G基站所采用的空口技术简称为5G空口，为了方便也可以采用其他命名方式，不具体限定。
从图1所示的架构图中可以看出，UE经由5G基站通过X5接口连接到eNB，进而连接到LTE核心网，从图2所示的架构图中可以看出，UE经由5G基站直接通过Sx接口连接到LTE核心网，而高层例如PDCP/RRC层在LTE。其中，X5接口为LTE eNB和5G基站之间的新定义的接口，Sx接口为LTE MME和5G基站之间的新定义的接口，X5接口和Sx接口也可以采用其他名称来表示相应网元之间的接口，并不具体限定接口名称。

可选的，步骤300还可以是：第二无线网络中的第二接入设备确认用户终端所承载的业务为使用第二无线接入技术传输的业务，向第一无线网络中的移动管理实体发送携带第一指示的第一消息。
例如，第一接入设备为图1或图2中的LTE eNB，第二接入设备为图1或图2中的5G基站。
所述第一消息可以为初始终端消息、承载修改指示消息，路径切换请求消息中的任意一种消息。
其中，所述第一接入设备和所述第二接入设备采用不同的无线接入技术， 第一接入设备可以为第一无线网络侧的基站，或者为第一无线网络接入网侧的其他网络设备；第二接入设备为第二无线网络的基站，或者为第二无线网络接入网侧的其他网络设备，例如第一接入设备是LTE制式的基站，第二接入设备是5G制式的基站。

可选的，所述第二消息可以为会话建立请求消息、承载修改指示消息中的任意一种消息。
步骤303：第一无线网络中的核心网网关接收第一无线网络中的移动管理实体发送的第二消息。
步骤304：所述核心网网关在确定所述第二消息中携带第一指示时，根据所述第二消息中的第一指示对发送到第二接入设备的所述用户终端承载的业务为第二无线接入技术传输的业务进行计费。

如图6所示，本发明实施例还提供一种计费方法流程图，图6的执行主体可以为第一无线网络侧的核心网网关。
如图6所示，该方法包括：
步骤600：第一无线网络中的核心网网关接收第一无线网络中的移动管理实体发送的第二消息。
步骤601：所述核心网网关在确定所述第二消息中携带第一指示时，对发送到第二接入设备的用户终端承载的业务为第二无线接入技术传输的业务进行计费，所述第一指示用于指示所述用户终端承载的业务为使用第二无线接入技术。
可选的，所述第二消息为会话建立请求消息、或承载修改请求消息。
具体的，以第一无线网络为LTE网络，第二无线网络为下一代移动通信网络，如第5代移动通信系统(The 5th Generation，5G)为例，通过以下三个实施例来详细说明图3中的方法的应用场景。5G所采用的空口技术简称为 5G空口，由于5G没有自己的核心网，但是用户面锚在LTE PDCP层进行数据包粒度或者承载粒度的分流，因此只能使用LTE的核心网对采用5G接入技术传输的业务进行计费。
在上述图1或图2所描述的架构下，5G的CP/UP面锚点在LTE PDCP层。5G有RLC/MAC/PHY层。即CP面通过LTE PDCP之后，经过5G空口RLC/MAC/PHY层发送给UE，UP面通过LTE PDCP之后，经过5G空口RLC/MAC/PHY层发送给UE。LTE eNB和5G基站的用户面和控制面协议栈分别如图7A和图7B所示，其中，X5接口为LTE eNB和5G基站之间的新接口，所述X5接口为新定义的接口，X5接口的用户面协议栈如图7C所示，X5接口的控制面协议栈如图7D所示。
实施例一
实施例一中的应用场景用于解决用户终端通过5G网络单独接入5G基站时的计费问题。图1或图2为该应用场景的网络架构图，涉及的网元包括UE，5G基站，和LTE网络侧的eNB即LTE eNB，MME和核心网网关，LTE核心网网关包括分组网关(Packet Gateway，PGW)和服务网关(serving Gateway，SGW)，具体流程参阅图8所示。
步骤801～步骤806：UE通过5G基站向LTE eNB发起无线资源控制(Radio resource Control，RRC)连接建立，通过LTE eNB接入LTE核心网，具体的：
步骤801：UE向5G基站发送无线资源连接请求消息。
具体的，该无线资源连接请求消息可以是LTE格式的RRC连接请求消息，如RRC connection request消息，也可以是其他定义格式的。
步骤802：5G基站将UE的无线资源连接请求消息转发给LTE eNB。
步骤803：LTE eNB通过X5接口发送无线资源连接建立消息给5G基站。
具体的，所述X5接口为LTE eNB和5G基站之间的接口，所述无线资源连接建立消息可以是RRC连接建立消息，具体的RRC连接建立消息可以是LTE格式的RRC连接建立消息，如RRC connection setup消息，也可以是其 他定义的格式。
步骤804：5G基站将LTE eNB的无线资源连接建立消息转发至UE。
步骤805：UE发起附着请求消息到5G基站。
具体的，附着请求消息可以是LTE格式的附着请求消息，如attach request消息，也可以是其他定义的格式。该消息包括在RRC连接建立完成消息中，RRC连接建立完成消息可以是LTE格式的RRC connection setup complete消息，也可以是其他定义的格式。
步骤806：5G基站接收到UE的attach request消息后，将UE的attach request消息通过5G基站和LTE eNB之间的接口，即X5接口转发给LTE eNB。
步骤807：LTE eNB发起初始终端(initial UE message)消息到MME，attach request消息承载在该initial UE message消息中，该initial UE message消息中携带第一指示，所述第一指示用于指示所述UE承载的业务为5G空口传输的业务。
步骤808：MME接收到初始终端消息后，和UE之间开始鉴权、非接入层(Non-Access-Stratum，NAS)安全、位置更新过程。
鉴权过程：鉴权过程是MME从用户签约的用户归属地服务器(Home Subscriber Server，HSS)获取鉴权向量(四元组)，并与UE完成网络和UE互相鉴权的过程。
NAS安全过程：NAS安全过程是UE和MME之间建立加密和完整性保护上下文的过程。在这个过程之后，MME和UE之间的NAS消息都会被加密和完整性保护，保证信令传送安全。
位置更新过程：鉴权和安全流程之后，网络侧就许可UE接入网络。此时，MME需要把UE的位置信息，主要是MME ID登记到HSS。此过程被称为位置更新(Update Location)过程。这个部分是MME和HSS之间使用直径(Diameter)协议通过S6a接口交互的过程。
步骤809～步骤810：安全认证结束之后，MME向SGW发起会话建立过程，网络各个节点为UE创建承载上下文，为用户面转发数据创建资源过程。 具体的：
步骤809：MME向SGW发起会话建立请求(create session request)消息，会话建立请求消息中携带第一指示。
可选的，SGW收到会话建立请求消息后，SGW会向PGW发起create session request消息。
步骤810：SGW接收到携带第一指示的会话建立请求消息后，返回会话建立响应(create session response)消息给MME，完成会话过程的建立。
可选的，PGW收到会话建立请求消息后，PGW会向SGW发起create seesion response消息。
具体的，SGW/PGW可以根据所述会话建立请求消息中的第一指示对使用5G空口传输的业务进行计费。
上述实施例一给出了UE通过5G基站接入LTE核心网时，通过LTE eNB向MME发送携带第一指示的初始终端消息，MME接收到携带第一指示的初始终端消息后，将第一指示携带在会话建立请求消息中发送至LTE核心网网关，使LTE核心网网关根据该第一指示完成对终端承载的5G空口传输的业务的计费。
可选的，在图2所示的网络架构中，UE向5G基站发送LTE格式的RRCConnection Request消息之后，如果5G基站和LTE MME之间存在Sx接口，所述Sx接口为5G基站和LTE MME之间新定义的接口，则5G基站可直接通过所述Sx接口向MME发起初始终端消息，所述初始终端消息中携带有LTE指示，此时无需通过LTE eNB进行转发，其他后续步骤同实施例一中图8的步骤808～步骤810一致，具体流程可参阅图9所示。
步骤901：UE向5G基站发送无线资源连接请求消息。
步骤902：5G基站发起初始终端消息到MME。
步骤903：MME接收到初始终端消息后，和UE之间开始鉴权、NAS安全、位置更新过程。
步骤904：MME向SGW发起会话建立请求消息，会话建立请求消息中 携带第一指示。
步骤905：SGW接收到携带第一指示的会话建立请求消息后，返回会话建立响应消息给MME，完成会话过程的建立。
实施例二
实施例二的应用场景用于解决用户终端在LTE eNB与5G基站的双连接场景下对5G空口传输的业务的计费问题。图1或图2为该应用场景的网络架构图，涉及的网元包括UE，5G基站，和LTE网络侧的eNB，MME和核心网网关，LTE核心网网关包括PGW和SGW。
对于终端采用双连接的方式，不同的承载选项有不同的配置，而用户面的连接取决于不同的承载选项，对于图2所示的网络架构，各网元之间的用户面连接关系如图10所示。
对于分裂承载(split bearers)，S1接口终止在LTE eNB，PDCP数据包通过X5接口在LTE eNB和5G新空口基站之间传输，其中，所述X5接口为LTE eNB和5G基站之间的接口。
对于5G小区组承载(5GCG bearers)，5G基站直接通过Sx接口和SGW连接，LTE eNB不参与用户面数据的传输，其中Sx接口为5G基站和LTE核心网间的接口，为本申请中新定义的接口。
对于图1所示的网络结构，由于，5G基站与SGW之间不存在接口连接关系，因此只能实现分裂承载。
对于双连接方式下的5G小区组承载有两种可选的实施方案，分别可参阅图11和图12。
具体的，方案一的具体流程如图11所示：
步骤1101～步骤1106：LTE eNB决定增加5G基站进行数据分流。
具体的：
步骤1101：UE从LTE eNB接入，接入成功后，LTE eNB决定增加5G基站进行数据分流，即发送5G基站增加请求(如，5G AI addition request)消息到5G基站。
步骤1102：5G基站接收到增加请求消息之后，返回5G基站增加请求响应(如，5G AI addition request ACK)消息到LTE eNB，所述增加请求响应消息中可能包括5G基站的相关配置信息。
步骤1103：LTE eNB收到增加请求响应消息之后，向UE发送RRC连接重配置(如，RRC connection reconfiguration)消息，所述RRC连接重配置消息中包括5G基站的相关配置信息。
步骤1104：UE接收到RRC连接重配置消息后接受5G基站的相关配置，同时向LTE eNB返回RRC连接重配置完成消息。如果不接受配置，则向LTE eNB返回RRC重配置失败消息。
步骤1105：LTE eNB接收到UE发送的RRC连接重配置完成消息后，向5G基站返回5G基站重配置完成消息，本步骤可选。
步骤1106：UE到5G基站进行随机接入过程。本步骤和步骤1104、步骤1105没有先后关系。
步骤1107：对于5G小区组承载，LTE eNB发送承载修改指示(eRAB modification indication)消息到LTE MME，通知MME承载路径改变，所述承载修改指示消息中携带第一指示。
所述第一指示用于指示所述UE承载的业务为通过5G空口传输的业务。
步骤1108：MME收到承载修改指示消息后，MME向SGW发起承载修改请求(如，bearer modification request)消息，所述承载修改请求消息中携带第一指示，SGW接收到承载修改请求消息后返回承载修改响应(如，bearer modification response)消息给MME。
在此步骤中，SGW可以根据第一指示来进行流量统计，比如，SGW分流部分承载通过5G空口与UE进行数据传输，则SGW可以根据第一指示，使用流量或者时间计费的方式对该部分承载进行计费。
具体的，由于SGW只能进行承载(bearer)的分流，则计费统计为一承载(per bearer)的粒度。
可选的，如果SGW在收到的承载修改请求消息(如，bearer modification  request)中收到了ULI(user location info)信元，则应该发送承载修改请求消息(如，bearer modification request)消息给PGW，PGW给SGW返回承载修改响应消息(如，bearer modification response)给SGW。所述承载修改请求消息中需携带第一指示，用于使PGW根据第一指示对UE所承载的业务为5G空口传输的业务进行计费。
具体的，SGW/PGW可以根据所述承载修改请求消息中的第一指示对使用5G空口传输的业务进行计费。
步骤1109：MME返回承载修改确认(如，eRAB modification confirmation)消息给LTE eNB。
具体的，方案二的具体流程如图12所示：
步骤1200：UE通过5G空口接入到5G基站，再通过X5接口通过LTE eNB接入到LTE核心网。
步骤1201：5G基站向LTE eNB请求增加自己进行数据分流，向LTE eNB发送5G基站增加请求消息。
后面的步骤类似上述方案一，方案一中的步骤1106不存在了，因为UE在步骤1200已经接入到5G基站。
步骤1202：LTE eNB接收到5G基站发送的增加请求消息后，决定增加5G基站进行数据分流，发送5G基站增加请求消息到5G基站。
步骤1203：5G基站接收到增加请求消息之后，返回5G基站增加请求响应(如，5G AI addition request ACK)消息到LTE eNB，所述增加请求响应消息中可能包括5G基站的相关配置信息。
步骤1204：LTE eNB收到增加请求响应消息之后，向UE发送RRC连接重配置消息，所述RRC连接重配置消息中包括5G基站的相关配置信息。
步骤1205：UE接收到RRC连接重配置消息后接受5G基站的相关配置，同时向LTE eNB返回RRC连接重配置完成消息。如果不接受配置，则向LTE eNB返回RRC重配置失败消息。
步骤1206：LTE eNB接收到UE发送的RRC连接重配置完成消息后，向 5G基站返回5G基站重配置完成消息，本步骤可选。
步骤1207：对于5G小区组承载，LTE eNB发送承载修改指示消息，通知MME承载路径改变，所述承载修改指示消息中携带第一指示。
步骤1208：MME收到承载修改指示消息后，向SGW发起承载修改请求消息，所述承载修改请求消息中携带第一指示，SGW接收到承载修改请求消息后返回承载修改响应消息给MME。
在此步骤中，SGW可以根据第一指示来区分流量统计，比如，SGW分流部分承载到5G基站，则可以根据第一指示，使用流量或者时间计费的方式对该部分承载进行计费。
具体的，由于SGW只能进行承载的分流，则计费统计为一承载的粒度。
可选的，如果SGW在收到的承载修改请求消息(如，bearer modification request)中收到了ULI(user location info)信元，则应该发送承载修改请求消息(如，bearer modification request)消息给PGW，PGW给SGW返回承载修改响应消息(如，bearer modification response)给SGW。所述承载修改请求消息中需携带第一指示，用于使PGW根据第一指示对UE所承载的业务为5G空口传输的业务进行计费。
具体的，SGW/PGW可以根据所述承载修改请求消息中的第一指示对使用5G空口传输的业务进行计费。
步骤1209：MME返回承载修改确认消息给LTE eNB。
对于分裂承载的双连接方式，在方案一或方案二中，UE向LTE eNB返回RRC连接重配置完成消息后，就没有后续步骤，流量统计直接在LTE eNB上统计，统计后上报到LTE MME/SGW/PGW，用于对UE所承载的业务为5G空口传输的业务进行计费。
上述实施例二给出了UE在5G基站与LTE eNB的双连接场景下，通过LTE eNB向MME发送携带第一指示的承载修改指示消息，MME接收到携带第一指示的承载修改指示消息后，将第一指示携带在承载修改请求消息中发送至LTE核心网网关，使LTE核心网网关根据该第一指示完成对UE所承载 的业务为5G空口传输的业务的进行计费。
实施例三
实施例三的应用场景适用于UE移动的场景，UE从源LTE eNB切换到了目标LTE eNB，源LTE eNB与5G基站正在进行数据分流，此时，当UE移动到目标LTE eNB后，目标LTE eNB为了保证数据分流的连续性，决定在切换过程中增加5G基站继续进行数据分流过程时对5G空口传输的业务的计费问题。增加5G基站继续进行数据分流过程在切换准备过程中进行。图1或图2为该应用场景的网络架构图，涉及的网元包括UE，5G基站，和LTE网络侧的eNB，MME和核心网网关，LTE核心网网关包括PGW和SGW。
切换分为三个阶段，切换准备阶段、切换执行阶段和切换完成阶段，其中切换完成阶段是和LTE核心网有交互消息的。
如图13所示，步骤1301～步骤1302：UE决定切换，进入切换准备阶段和切换执行阶段。
在此过程中，UE从源LTE eNB切换到目标LTE eNB，源LTE eNB和5G基站正在进行数据分流。切换到目标LTE eNB后，目标LTE eNB决定增加5G基站继续数据分流过程。
切换准备过程包括源eNB向目标eNB发起切换请求消息、目标eNB向5G基站发起增加请求消息可参阅实施例二，切换执行过程包括UE向目标LTE eNB和5G基站进行随机接入过程等。
切换流程可借鉴LTE X2口的LTE eNB之间的切换相关流程。
步骤1303：切换执行后，在切换完成阶段内，目标LTE eNB向MME发起路径切换请求(如，path switch request)消息，该路径切换请求消息用于通知MME UE已经更换了小区，MME决定采用哪个SGW继续为该UE服务，并重新分配SGW。该路径切换请求消息中携带第一指示。
所述第一指示用于指示所述UE承载的业务为使用5G空口传输的业务。
步骤1304～步骤1305：MME接收到路径转换消息后，决定是否更改SGW。
可选的，如果SGW不更改，此时执行
步骤1304：MME向源SGW/PGW发起承载修改请求(如，bearer modification request)消息，该承载修改请求消息中携带第一指示。
具体的，SGW/PGW可以根据所述消息中的第一指示对使用5G空口传输的业务进行计费。
步骤1305：源SGW的下行数据传输隧道切换到目标LTE eNB之后，SGW发送承载修改响应(如，bearer modification response)消息给MME。与实施例二中类似。
可选的，此处如果源SGW在承载修改请求消息(如，bearer modification request)中收到了用户位置(user location info，ULI)的信元，则应该发送承载修改请求消息(如，bearer modification request)给PGW，PGW返回承载修改响应消息(如，bearer modification response)给SGW。
步骤1306：MME返回路径切换请求确认(如，path switch request ack)消息给目标LTE eNB。
步骤1307：目标LTE eNB向源LTE eNB发起释放资源请求(如，Release resource)消息。
可选的，如果SGW更改，参阅图14所示，此时：
步骤1401～步骤1403与图13中的步骤1301～步骤1303完全相同，在此不再赘述。
步骤1404：MME重新分配新的SGW，并向新的SGW/PGW发起会话建立请求(如，create session request)消息，所述会话建立消息中携带第一指示。
步骤1405：SGW/PGW接收MME发送的会话建立请求消息，返回会话建立响应(如，create session response)消息给MME，这与实施例一中类似。
具体的，SGW/PGW可以根据所述会话建立请求消息中的第一指示对使用5G空口传输的业务进行计费。
步骤1406：MME返回路径切换请求确认(如，path switch request ack)消息给目标LTE eNB。
步骤1407：目标LTE eNB向源LTE eNB发起释放资源请求(如，Release resource)消息。
进一步的，图14中还包括步骤1408～步骤1409，即MME向源SGW发起释放会话请求消息，并接收源SGW返回的释放会话确认消息。
上述实施例三给出了UE从与5G基站正在进行数据分流的源LTE eNB切换到了目标LTE eNB后，为了保证数据分流的连续性，目标LTE eNB决定增加5G基站继续进行数据分流的场景下，通过目标LTE eNB向MME发送携带第一指示的路径切换请求消息，MME接收到携带第一指示的路径切换请求消息后，将第一指示携带在承载修改请求消息或会话建立请求消息中发送至LTE核心网网关，使LTE核心网网关根据所述第一指示完成UE承载的业务为5G空口传输的业务的计费。

如图21所示，本发明实施例还提供了一种计费方法，包括步骤S2101-S2102：
S2101：第一接入设备对由第二接入设备传输的用户终端的业务进行流量统计。
可选地，第一接入设备与第二接入设备也可以采用不同的无线接入技术。例如在LTE与WLAN融合(LWA，LTE-WLAN aggregation)场景中，第一接入设备是LTE网络中的演进型基站(eNodeB/eNB,evolved NodeB)，第二接入设备是WLAN中的无线局域网端点(WT，WLAN Termination)。eNB与WT之间存在通信接口，包括数据面接口和控制面接口，WT管理了至少一个接入点(AP，access Point)。WT可以对eNB传输的用户终端的业务进行数据分流，即由WT传输用户终端的部分业务，减少eNB的负荷。eNB可以对通过WT传输的用户终端的业务进行流量统计。又例如，在LTE与5G双连接的场景中，第一接入设备可以是LTE网络中的基站(eNB)，第二接入设备可以是5G网络中的基站设备，关于LTE与5G双连接的场景的详细描述可以参照本发明其他实施例的相关内容，在此不做赘述。
可选地，第一接入设备与第二接入设备可以采用相同的无线接入技术，例如在双连接(DC，dual connectivity)场景中，第一接入设备是主基站(MeNB，master eNB)，第二接入设备是辅基站(SeNB，secondary eNB)。SeNB可以对MeNB传输的用户终端的业务进行数据分流，即由SeNB传输用户终端的 部分业务，减少MeNB的负荷。MeNB可以对通过SeNB传输的用户终端的业务进行流量统计。其中，MeNB和SeNB是相同制式的基站设备，例如都是LTE制式的。
可选地，由第二接入设备传输的业务可以包括以下任意一个或多种：
数据报文中的互联网协议IP报头或者TCP/UDP头，TCP(传输控制协议)控制报文，重传数据包。
可选地，具体的第一接入设备进行流量统计的粒度可以是承载粒度的，如果第一接入设备和第二接入设备支持网络切片(network sliceing)，那么统计的粒度可以是各个切片功能下承载粒度或者各个承载下不同切片粒度的。进一步的，如果第一接入设备具备深度解析功能(DPI，Deep Packet Inspection)，则第一接入设备就可以感知具体业务，从而可以区分不同的业务使用了不同的流量。
S2102：第一接入设备向核心网实体发送流量指示消息，所述流量指示消息包括所述业务的流量信息，所述流量信息用于所述核心网实体对所述业务进行计费。
其中，所述流量信息可以是第一接入设备对分流到第二接入设备的业务的流量统计值。
可选地，在本发明的另一个实施例中，第一接入设备可以确定将用户终端的部分业务转移到所述第二接入设备传输；并对转移到所述第二接入设备的业务进行流量统计。
S2103：核心网实体根据接收到的流量指示消息中的流量信息，对由所述第二接入设备传输的用户终端的业务进行计费。
可选地，所述核心网实体可以是MME和/或SGW。，可选地，可以由MME或者SGW单独进行计费，也可以由MME和SGW合作完成计费。
可选地，本发明实施例对流量指示消息的具体类型不做特别限定。例如，流量指示消息可以是新建的S1接口消息，专门用于传输上述流量信息，其中S1接口是第一接入设备与核心网实体之间的接口；或者，流量指示消息也可 以是现有的在第一接入设备与核心网设备之间传输的消息，例如，在LWA场景中，eNB可以通过现有的无线接入承载修改指示(E-UTRAN Radio Access Bearer，ERAB，modification indication)消息把流量信息上报到MME，并由MME通过承载修改(bearer modification)消息再将流量信息从MME上报到SGW，由SGW完成计费。
图22是图21实施例提供的计费方法的信令流程示意图，为清楚描述，以第一接入设备为eNB，第二接入设备为WT为例进行说明。可以理解，本发明实施例对接入设备的具体类型不做任何限定。
S2201：eNB向WT发送WT增加请求(WT Addition Request)消息，用于请求该WT为eNB进行数据分流。
S2202：WT向eNB发送WT增加请求确认(WT Addition Request Acknowledge)消息。
其中，所述WT增加请求确认消息中包含WT的相关配置信息，该配置信息具体可以包括承载信息，移动性控制信息，移动集(mobility set)等，其中，移动集可以包括可接入的AP的标识列表。
S2203：eNB向用户终端发送RRC连接重配置(RRC Connection Reconfiguration)消息。
其中，所述RRC连接重配置消息中包含WT的相关配置信息。
S2204：用户终端向eNB发送RRC连接重配置完成(RRC Connection Reconfiguration Complete)消息。
用户终端发送上述RRC连接重配置完成消息后，可以采用上述WT的相关配置信息，进入LWA工作模式。例如，用户终端根据步骤2202中配置信息包含的移动集，关联其中一个可接入的AP。
S2205：eNB接收到用户终端反馈的RRC连接重配置完成消息后，确定将所述用户终端的部分业务转移到WT传输。
S2206：WT向eNB发送WT关联确认(WT Association Confirmation)消 息。
S2207：用户终端向eNB发送WLAN连接状态报告(WLAN Connection Status Report)。
其中，SS207为可选的步骤。
S2208：eNB对转移到WT传输的用户终端的业务进行流量统计。
S2209：eNB向MME发送流量指示消息。
S2210：MME向SGW发送流量指示消息。
S2211：SGW获取流量指示消息中的流量信息，对用户终端的业务进行计费。
关于流量指示消息以及流量信息的详细描述可以参照本发明其他实施例的相关描述，例如图21所示实施例，在此不做赘述。
采用本发明实施例提供的计费方法，由第一接入设备对分流到第二接入设备的业务进行流量统计，进而通过流量指示消息指示核心网设备对这部分分流业务进行计费，实现了分流业务的单独计费，并减轻了核心网的负荷。
