Description

一种移动宽带数据传输的管理方法和装置 技术领域
本申请涉及但不限于移动通信领域，尤其涉及3GPP(3rd Generation Partnership，第三代合作伙伴计划)家族制式内的蜂窝移动系统中一种利用多个WLAN接入节点(Access Point，AP)实现移动宽带数据传输的方式方法和系统。
背景技术
3GPP(3rd Generation Partnership，第三代合作伙伴计划)家族制式内的蜂窝移动系统可以包括长期演进系统(LTE，Long Term Evolution，包括网络侧NW和终端侧UE)及其后续下一代蜂窝系统，和无线局域网系统(WLAN，Wireless Local Access Network，包括网络侧和终端侧)及其后续下一代系统如HEW(High Efficient WLAN，高效无线局域网)之间的跨系统联合互操作工作模式。
随着移动通信运营商签约用户数和用户语音数据等移动业务量的不断增多，未来呈现出指数级别地增长，移动通信网络基础设施的投入和部署规模也必须要相应地扩增，使得无线覆盖的广度深度和系统通信容量都能应对满足用户不断增长的客观需求。以欧洲大部分移动通信运营商为例，它们在历史上先后部署了3种不同RAT(Radio Access Technology，无线接入技术)制式的移动通信系统(它们都是3GPP通信系统家族内的制式):GSM(Global System of Mobile communication，全球移动通信系统)、UMTS(Universal Mobile Telecommunications System，通用移动通信系统)和LTE，这些蜂窝式移动系统都工作在授权频谱内的授权载波上。为了进一步增强移动通信网络的功能和扩充系统容量，移动通信运营商还广泛大量地部署了IEEE通信系统家族内诸如WLAN系统(正在朝着下一代HEW系统演进)，用来作为有效且低成本的无线容量补充。虽然不能高性能地独立组建类似3GPP式的蜂窝移动网，但因为WLAN系统比3GPP系统在物理实现上要技术简单且成本低廉地很多，且工作在免费的且带宽更为广阔的非授权频谱内的非授权载波 上，因此有着其强大的市场生命力和竞争力。
由于上述多种无线通信系统(Multi-RAT)长期地演进共存部署着，共同提供着无线接入和数据传输服务，为了增强跨系统间的移动性能，增强用户移动通信的关键性能指标(KPI，Key Performance Indicator)体验，节约软硬件开发维护成本，便于运营商们对“Multi-RAT大网”的运维管理，3GPP已经开发制定出了多种版本的标准化技术，把上述各种无线通信系统以不同程度/级别的方式耦合在一起工作，形成所谓跨系统联合互操作。如图1中的一个网络架构例子所示：WLAN AP和3GPP的3种主要无线接入网单元共同连接于同一个融合核心网(CN，Core Network)上，运营商能够较灵活地协同传输不同RAT间的能力/配置/状态等信息，制定合理的移动策略，根据业务QOS(Quality of Service，服务质量)特点和资源状态的需要，让UE被服务于最合适的RAT基站/小区下。增强不同RAT间联合互操作的好处在于：不同RAT可以更好地发挥出各自系统的优势特点，不同RAT间可以更加灵活均衡地去分担广大用户的无线通信负荷，不同RAT间能够形成硬件资源、无线覆盖和容量的动态互补，从而为整个“Multi-RAT大网”带来更高性能KPI，为广大用户带来更好的移动通信体验和感受。
根据相关公开技术，具备WLAN/3GPP多模能力的终端，可以同时和AP或者WLAN未来演进或革命系统的接入节点和3GPP家族中某种RAT的基站同时处于通信连接/数据传输状态。下面将集中以WLAN和LTE系统间联合互操作为例(思想原理对于其他RAT间的联合互操作基本也都适用)，比如某种WLAN/LTE双模能力的终端同时处于WLAN/LTE小区的无线信号覆盖下，某时刻该终端率先和LTE网络建立RRC(Radio Resource Control，无线资源控制)连接，继而进行某种IP业务流A的双向数据传输，后来用户又发起了一个新的IP业务流B。在用户手动控制模UP(User Preference，用户偏好)下，终端搜寻发现了WLAN的覆盖信号并且完成了必要的AP入网关联鉴权注册(这个过程称为WLAN选网注册)，随后融合CN可以根据一定的策略规则和上层协议信令，把IP业务流B迁移到终端之前已经成功注册的WLAN系统中，此后终端的IP业务流A仍然承载在LTE网络中，而IP业务流B承载在WLAN网络中(这个过程称为WLAN数据分流)，上述基 本过程如图2a/2b示意。
截止到3GPP Rel-13版本，针对WLAN-LTE的耦合联合互操作已经有多种基本机制，除了上面示例的手动配置UP，还有(e)ANDSF(Enhacend Access Network Discovery Selection Function，增强的接入网络发现选择功能)，(e)ITW(Enhanced RAN Rule Based Interworking，增强的基于接入网规则的互操作机制)，LWA(LTE WLAN Aggregation，LTE和WLAN系统间聚合)等机制。上述这些机制除了LWA机制之外，都需要依赖UE释放掉原本在LTE网络内的IP Flow/DRB(Data Radio Bearer，数据无线承载)无线承载，通过WLAN空口信令和目标AP建立/维护WLAN连接，实现承载用户业务数据的IP Flows在核心网侧的迁移和分流；而作为紧耦合方式的LWA机制并不会导致IP Flows在核心网侧的迁移，仅仅让LTE网络内的IP Flow/DRB无线承载的用户面部分数据通过相互紧耦合的目标AP来传输，由无线接入侧的锚点MeNB来控制目标AP的添加/重配/删除和相关分流数据的转发回收等，可以理解为：MeNB(主基站节点)是所有处于LWA工作模式下的AP的集中控制节点。
过去3GPP针对上述机制的广泛讨论中，都是基于“单AP连接能力”的UE，即特定UE在某个特定时刻最多只能和一个目标AP发生关联认证，同时只能通过一条WLAN空口链路进行数据传输。这种“单AP连接能力”的UE通常在内部只配置了一套WLAN相关的射频基带资源，这种UE能力配置上的物理限制有如下缺点：
如果运营商网络侧部署的3GPP系统相关资源较少(比如：部署的LTE授权载波少且窄，3GPP系统相关的BU(Branching Unit，支路单元)处理资源少)，而网络侧部署的WLAN相关的资源较多(比如：部署的WLAN非授权载波多且宽，WLAN系统相关BU处理资源多)，那么对于“单AP连接能力”UE，它必然和网络侧的能力配置比例发生失衡(Mismatch)，造成UE内的3GPP相关能力资源部分被闲置，而由于UE只有一套WLAN资源模块，却无法充分地利用网络侧的WLAN资源。

本发明的实施方式
下面将结合附图及具体实施例对本申请作进一步的详细描述。需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互任意组合。
图3为本发明实施例提供的移动宽带数据传输的管理方法的流程图。图3所示方法包括以下步骤：
步骤301、获取终端内至少两套WLAN资源功能模块的能力信息；
步骤302、根据所述能力信息，逐个为所述至少两套WLAN资源功能模块配置与对应的AP或者WLAN未来演进或革命系统的接入节点进行关联认证；
其中，在LTE系统中，AP或者WLAN未来演进或革命系统的接入节点为AP，当然，在LTE的未来演进系统中AP或者WLAN未来演进或革命系统的接入节点为具有LTE中AP的功能的节点；
相应地，当系统为WLAN未来演进或革命系统时，该WLAN资源模块也适应具有与该系统匹配的功能；
步骤303、管理所述终端利用所述至少两套WLAN资源功能模块与对应的AP或者WLAN未来演进或革命系统的接入节点进行移动宽带数据的传输。
其中，“管理”具体指：每条WLAN链路的各自独立的建立、配置、重配、维护、删除等基本动作，基本操作和已有的单WLAN链路一致。
本发明实施例提供的方法，利用终端内至少两套WLAN资源功能模块，分别为每个WLAN资源功能模块建立与接入节点的连接，实现终端与网络侧有多条传输链路，提高了数据传输效率，且充分利用了网络侧的资源。
下面对本发明实施例提供的方法做进一步说明：
其中，所述WLAN资源功能模块的能力信息包括非LWA机制能力信息、支持的WLAN射频频段和工作带宽中的至少一个。
具体而言，通过获知WLAN资源功能模块的能力信息，可以根据该能力信息，为该WLAN资源模块选择合适的AP或者WLAN未来演进或革命系统的接入节点，以保证建立的连接的稳定性。
另外，所述根据所述能力信息，逐个为所述至少两套WLAN资源功能模块配置与对应的AP或者WLAN未来演进或革命系统的接入节点进行关联认证，包括：
获取所述终端内处于闲置状态的WLAN资源功能模块；
对所述处于闲置状态的WLAN资源功能模块进行配置。
具体而言，在对WLAN资源功能模块逐个配置过程中，有可能存在部分模块正处于工作状态，如果对处于工作状态的模块进行配置，会影响该模块正在传输的数据，造成数据传输中断的问题，因此，为了保证配置过程中不影响UE内数据的正常传输，需要在进行配置前，对模块的工作状态进行检测，以避免因配置操作造成数据中断的问题。
其中，任意两套WLAN资源功能模块连接的AP或者WLAN未来演进或革命系统的接入节点不同。
具体而言，每套WLAN资源功能模块连接的AP或者WLAN未来演进或革命系统的接入节点得到的链路，对应于UE和网络侧AP或者WLAN未来演进或革命系统的接入节点间建立的多WLAN工作链路，在建立的时间顺序上，如果条件被满足，可以同时被建立，即只有逻辑上处理先后的顺序差别，没有时间上较大的先后建立差别。
由于不同的链路逻辑上独立存在于网络侧AP或者WLAN未来演进或革命系统的接入节点和UE内多套WLAN功能模块之间，因此它们可以彼此独立地工作，任何一条WLAN链路的工作状态变化不会影响到其他WLAN链路的工作状态，仅仅受到3GPP网络侧为每条WLAN链接配置的策略准则参数等控制和状态条件的影响。
其中，所述管理所述终端利用所述至少两套WLAN资源功能模块与对应的AP或者WLAN未来演进或革命系统的接入节点进行移动宽带数据的传输，包括：
控制所述终端内的主WLAN链路去分流承载或者反向卸流去承载UE中的移动宽带数据；
控制所述终端内的第n个辅WLAN链路去分流承载或者反向卸流去承载UE中的移动宽带数据；其中，所述第n个辅WLAN链路承载的IP Flows来自UE在3GPP网络侧剩下的移动宽带数据；或者，是主WLAN链路、第1个至第n-1个辅WLAN链路已经分流承载的移动宽带数据；其中，n<m-1，n和m均为正整数，m为所述终端内WLAN资源功能模块的总数。
为方便理解，下面以一具体流程进行说明：
下文以系统为LTE为例进行说明：
S1：在UE内部某套WLAN资源功能模块的能力范围内，3GPP网络侧基于它能支持的某种非LWA机制，按照相关技术方式，让网络侧部署的某AP1节点和该UE内该套WLAN资源功能模块先形成关联连接，完成必要的WLAN入网鉴权注册等过程，此时UE被建立而获得主WLAN链路PWL(Primary WLAN Link)。成功建立后，3GPP网络侧基于该套非LWA机制相关技术，让AP1和UE进行相关的空口上下行数据传输，即按照该非LWA机制所规定的策略准则参数等，用PWL去分流承载或者反向卸流去承载UE中的部分IP Flows。
S2：在S1之后，如果UE内还有某套WLAN资源功能模块处于闲置没被利用的状态，则在该套WLAN资源功能模块的能力范围内，3GPP网络侧基于它能支持的某种非LWA机制，在一定的条件下，按照相关技术方式，让网络侧部署的某AP2节点和UE内该套WLAN资源功能模块形成关联连接，完成必要的WLAN入网鉴权注册等过程，此时UE被建立而获得第一辅WLAN链路SWL(1st Secondary WLAN Link)。成功建立后，3GPP网络侧基于该套非LWA机制相关技术，让AP2和UE进行相关的空口上下行数据传输，即按照该非LWA机制所规定的策略准则参数等，用1st SWL去分流承载或者反向卸流去承载UE中的部分IP Flows。1st SWL承载的IP Flows可以来自UE在3GPP网络侧剩下的用户数据流，也可以是PWL已经分流承载的用户数据流。
S3：类似S2处理的原则方式，3GPP网络侧继续检测UE内部尚未被利用的WLAN资源功能模块，基于它能支持的某种非LWA机制，在一定的条件下，按照相关技术方式，尝试让网络侧部署的其它APx节点和UE内该套WLAN资源功能模块形成关联连接，完成必要的WLAN入网鉴权注册等过程，此时UE被建立而获得更多的第二/第三/第四等辅WLAN链路SWL(2nd/3rd/4th…Secondary WLAN Link)。成功建立后，3GPP网络侧基于该套非LWA机制相关技术，让APx和UE进行相关的空口上下行数据传输，即按照该非LWA机制规定的策略准则参数等，用更多的2nd/3rd/4th…SWL去 分流承载或者反向卸流去承载UE中的部分IP Flows。2nd/3rd/4th…SWL承载的IP Flows可以来自UE在3GPP网络侧剩下的用户数据流，也可以是之前PWL和1st SWL已经分流承载的用户数据流，后续依次递推。
需要说明的是，PWL和1st,2nd,3rd,4th…SWL之间既可以是基于同一种非LWA机制所对应的策略准则参数等(对应3GPP网络侧为所有目标APs配置同一套策略准则参数等)，和在相同的状态条件下建立而成，这种情况下PWL和1st,2nd,3rd,4th…SWL之间除了名称不同为了方便描述上的区别，实质并无本质差别(可以都称为PWL)；PWL和1st,2nd,3rd,4th…SWL之间也可以是基于不同种的非LWA机制所对应的策略准则参数等(对应3GPP网络侧为不同的目标APs配置不同的策略准则参数等)，或在不同的状态条件下建立而成，这种情况下PWL和1st,2nd,3rd,4th…SWL之间有着分流能力和建立/维护/释放等方面的多重差别，因此需要更严格地被区分。
另外，在检测如下条件时，停止为所述至少两套WLAN资源功能模块配置与对应的接入节点AP或者WLAN未来演进或革命系统的接入节点进行关联认证的操作：
条件一：UE内部所有的WLAN资源功能模块都已经被利用；
条件二：未找到与WLAN资源功能模块的能力信息匹配的AP或者WLAN未来演进或革命系统的接入节点。
其中，通过如下方式判断是否有与WLAN资源功能模块的能力信息匹配的LTE或者LTE未来演进或革命的接入节点：
根据终端的所述能力信息，确定与终端内与WLAN资源功能模块的能力信息匹配的AP或者WLAN未来演进或革命系统的接入节点的能力信息，其中，所述AP或者WLAN未来演进或革命系统的接入节点的能力信息包括AP或者WLAN未来演进或革命系统的接入节点的信号覆盖强度、无线负荷、回传带宽、WLAN鉴权信息和WLAN注册信息中的至少一个；
根据所述AP或者WLAN未来演进或革命系统的接入节点的能力信息，查找具有所述AP或者WLAN未来演进或革命系统的接入节点的能力信息的AP或者WLAN未来演进或革命系统的接入节点。
当然，在停止为所述至少两套WLAN资源功能模块配置与AP或者WLAN未来演进或革命系统的接入节点进行关联认证的操作之后，所述方法还包括：
获取所述UE内部所有的WLAN资源功能模块的工作状态和/或AP或者WLAN未来演进或革命系统的接入节点的能力信息；
在所述UE内有处于闲置状态的WLAN资源功能模块的工作状态和/或有与WLAN资源功能模块的能力信息匹配的AP或者WLAN未来演进或革命系统的接入节点后，启动为所述至少两套WLAN资源功能模块配置与对应的接入节点AP或者WLAN未来演进或革命系统的接入节点进行关联认证的操作。
由此可以看出，在资源能力不符合建立“多AP连接”时，及时停止建立流程，通过对UE和网络侧资源的能力信息的管理，可以对建立“多AP连接”的流程进行管理，以保证及时建立“多AP连接”，尽可能地多利用网络侧多WLAN APs资源和UE内多套WLAN功能模块资源，提高资源的利用率。
下面以两个实施例对上述方法作以说明。
实施例一
如图4所示，某运营商部署了LTE宏小区(Macro Cell)网络提供用户基本无线覆盖，为了增强网络容量，该运营商进一步在非授权2.4G和5G频段内的某非授权载波频点上，又分别部署了40M带宽的WLAN APs，用来分流承载用户业务的IP Flows。某终端UE 1正常驻留在LTE宏小区内，和基站(eNB)保持着无线资源控制(RRC)连接态，同时该UE 1也处于多个WLAN APs无线信号覆盖之下。
S100：UE 1内部硬件装配了：1套能支持2.4G频段40M带宽的WLAN射频基带功能模块A(简称WLAN模块A)+1套能支持5G频段40M带宽的WLAN射频基带功能模块B(简称WLAN模块B)，通过LTE空口RRC信息上报给了eNB，从而LTE网络侧获悉UE 1能支持“多AP连接”的相关能力。此外UE 1的两个WLAN模块都支持ITW联合互操作机制。
S101：eNB通过RRC专有信令给UE 1的WLAN模块A配置和ITW相关的策略准则参数，在特定的WLAN条件下，按照相关ITW技术方式，2.4G频段上的某AP1节点和UE 1内WLAN模块A先形成了关联连接，完成必要的WLAN入网鉴权注册等过程，此时UE 1被建立而获得主WLAN链路PWL。成功建立后，原先承载在LTE宏小区内的某些IP Flows被PWL分流出去。
S102：eNB进一步通过RRC专有信令给UE 1的WLAN模块B配置和ITW相关的策略准则参数，在特定的WLAN条件下，按照相关ITW技术方式，5G频段上的某AP2节点和UE 1内WLAN模块B也能形成了关联连接，完成必要的WLAN入网鉴权注册等过程，此时UE 1被建立而获得一条辅WLAN链路SWL。成功建立后，原先承载在LTE宏小区内的某些IP Flows又能被SWL分流出去。
注：由于WLAN系统在空口基于非授权无线资源竞争的LBT(Listen Before Talk，先听后说)的工作方式，因此UE 1内两套WLAN模块在频谱垂直面上，无法进行像LTE载波聚合那样的操作(WLAN模块无法对齐多个数据块的传输时间)。UE 1同时和两个目标APs进行WLAN数据分流，这能进一步增强LTE宏网络向WLAN网络的分流能力，提升用户数据吞吐率。
S103：由于UE 1只有两套WLAN模块，且都已经被利用，因此无法建立更多的SWL。
S104：虽然eNB暂时检测到UE 1内部所有的WLAN模块都已经被利用，但是随着UE位置移动和WLAN自身条件的变化(比如信号覆盖强度质量，无线负荷)，还需要轮询检测更新地去做“双AP连接”，尽可能地去多利用网络侧WLAN APs资源和UE内两套WLAN模块。UE 1在2.4G和5G频段内的目标AP节点会独立地发生更新变化，而分流的IP Flows具体情况继续按照eNB分别配置的ITW相关的策略准则参数而进行。
实施例二
如图5所示，某运营商部署了LTE宏小区网络提供用户基本无线覆盖，为了增强网络容量，该运营商进一步在非授权2.4G的某非授权载波频点 上，又连续相邻部署了80M带宽的WLAN APs，用来分流承载用户业务的IP Flows。某终端UE 2正常驻留在LTE宏小区内，和eNB基站保持着RRC连接态，同时该UE 2也处于两个相邻的WLAN APs无线信号的重叠覆盖之下。
S200：UE 2内部硬件装配了：2套能支持2.4G频段80M带宽的WLAN射频基带功能模块(简称WLAN模块A/B)+1套能支持5G频段80M带宽的WLAN射频基带功能模块C(简称WLAN模块C)，通过LTE空口RRC信息上报给了eNB，从而LTE网络侧获悉UE 2能支持“多AP连接”的相关能力。此外UE 2的3个WLAN模块都支持eANDSF联合互操作机制。
S201：eNB通过RRC专有信令给UE 2的WLAN模块A/B配置和eANDSF相关的策略准则参数，在特定的WLAN条件下，按照相关eANDSF技术方式，2.4G频段上的某AP1节点和UE 2内WLAN模块A先形成了关联连接，完成必要的WLAN入网鉴权注册等过程，此时UE 2被建立而获得主WLAN链路PWL。成功建立后，原先承载在LTE宏小区内的某些IP Flows被PWL分流出去。
S202：进一步地，在特定的WLAN条件下，按照相关eANDSF技术方式，2.4G频段上与AP1节点相邻的AP2节点也和UE 2内WLAN模块B形成了关联连接，完成必要的WLAN入网鉴权注册等过程，此时UE 2被建立而获得一条辅WLAN链路SWL。成功建立后，原先承载在LTE宏小区内和PWL上的某些IP Flows又能被SWL分流出去。
注：由于WLAN系统在空口基于非授权无线资源竞争的LBT(Listen Before Talk)的工作方式，因此在同一WLAN非授权工作频点上的AP1和AP2不一定能同时地向UE 2发送数据块，谁先成功抢占到本地信道资源，谁就可以发送数据块。网络侧也可以选择让相邻的AP1和AP2承载相同的IP Flow，形成发送接收分集增益。
S203：虽然UE 2还有1套闲置的WLAN模块C，但是因为网络侧没有提供5G频段内的WLAN AP节点资源，因此无法建立更多的SWL。
S204：虽然eNB暂时检测到UE 2内部所有的WLAN模块都已经尽可能地被利用，但是随着UE位置移动和WLAN自身条件的变化(比如信号覆盖 强度质量，无线负荷，进入到5G频段内WLAN AP节点覆盖范围内)，还需要轮询检测更新地去做“多AP连接”，尽可能地去多利用网络侧WLAN APs资源和UE内3套WLAN模块。UE 2在2.4G或者5G频段内的目标AP节点会独立地发生更新变化，而分流的IP Flows具体情况继续按照eNB分别配置的eANDSF相关的策略准则参数而进行。
