Description

一种进行服务质量管理的方法
本申请要求在2015年05月26日提交中国专利局、申请号为201510275222.9、发明名称为“一种进行服务质量管理的方法和设备”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明涉及无线通信技术领域，特别涉及一种进行服务质量管理的方法和设备。
背景技术
新型分布式网络是指大量终端(即末端节点，End Point，EP)分布式部署，并通过本地控制节点根据需要接入高层网络的方式。分布式网络是解决大量终端部署和端到端时延的有效方式。
如图1A所示，分布式网络中一个簇头和一系列末端节点(EndPoint)构成一个簇，簇内EndPoint通信通过簇头设备进行控制。簇头与EndPoint之间采用静态配置的信道与安全参数。各个簇之间相互独立，不同簇间的EndPoint成员无法相互通信。
如图1B所示，现有的蜂窝系统中，终端根据下行导频信号强度确定业务基站，业务基站负责为接入终端提供数据传输业务。业务基站将从终端接收到的上行数据转发给核心网，核心网负责为接入终端提供到外部网络的连接业务。
传统的分布式网络没有固定的拓扑和骨干，网络中的节点要同时充当主机和路由器，并通过存储转发技术帮助其他节点构成信息链路，簇头管理簇成员之间的通信，簇之间的通信通过网关进行。簇头不负责成员节点的QoS保障，节点在簇之间移动时只是数据路径的转移。
现有LTE系统中，终端在基站间切换时网络仍对终端进行QoS保障，切换过程中，终端始终处于连接态，核心网保留和利用用户签约信息，对用户服务质量进行保障。但在分布式网络中，簇头不是基站，只能进行简单的控制功能，且终端不是由核心网统一控制的。
与LTE系统比，分布式网络没有核心网控制，不能沿用LTE机制保证终端从一个簇移动到另一个簇过程中的用户服务质量。
综上所述，目前对于分布式网络进行终端服务质量管理的方案。

蜂窝接入网主要为传统手持或车载式接入设备(Device)或称为调制解调器(Modem)提供接入服务，此外蜂窝接入网还可以为MESH接入网提供到核心网的信令与数据的回传服务。

DSC支持软硬件解耦合和软件可配置功能。DSC负责对EP类型的终端(也可称为末端节点)接入进行控制，DSC需要在终端接入过程中对终端身份进行验证。由于核心网采用基于簇的管理策略，因此DSC负责将自身管理的簇信息上报核心网，其中簇信息包括DSC管理的簇内成员数量信息、DSC管理的簇内激活的服务信息等。
3、本地服务中心LocalServiceCenter(LSC)：
LSC，用于通过回传网络，与核心网之间传输与特定接入设备相关的信息；其中，特定接入设备是接入到与LSC连接的基站或AP的接入设备。
可选的，LSC还对特定接入设备进行连接管理和传输管理。
具体的，传输管理包括下列管理中的部分或全部：
进行跨基站和/或跨AP的干扰管理；

LSC还可以根据本地接入网中AP，BS以及接入Device测量到得干扰信息通知给周围DSC或LSC；
相应的，周围DSC或LSC判断自身对其他簇或“本地接入网”通信造成干扰，则可以通过降低发射功率等方式，弱化干扰。
在实施中，本发明实施例的蜂窝接入网有多个可相互交叠的蜂窝本地接入网构成。蜂窝本地接入网中的基站可以是各种类型的基站。
LSC与基站或接入点AP共同构成蜂窝本地接入网，其中如果蜂窝本地接入网由LSC与基站共同构成，则负责为特定地理区域提供广域覆盖；如果蜂窝本地接入网由LSC与AP共同构成，则负责为热点容量增强服务。蜂窝接入网有多个可相互交叠的蜂窝本地接入网构成。
4、基站(BS)：

5、接入点AP：

具体的，AP可以进行下列功能中的部分或全部：
负责对无线接入过程进行控制。
负责对物理层无线传输相关的基带处理功能。
为单小区传输，进行无线资源调度和传输参数配置。
在无设备接入情况下，可进入静默模式从而降低耗电。
6、设备Device：
Device可以是终端、Modem设备还可以是其他能够通过蜂窝接入网接入网络的设备。
可选的，Device本身还可以为MESH接入网成员提供到核心网或外部网络的中继服务。
可选的，本发明实施例的Device可以支持在高速情况下(例如，移动速度超过500km/h)，接入蜂窝网(例如与基站天线直线距离超过1500m)，并且支持非常高的数据传输速率(例如数据传输速率大于1Gbps)。
可选的，本发明实施例的Device可以通过系统广播信道接收广播服务信息。
可选的，本发明实施例的Device可以通过接入蜂窝网络获得数据传输服务。
可选的，本发明实施例的Device可以实现设备间进行直接通信。
7、网络服务中心NetworkServiceCenter(NSC)：
NSC负责终结接入网到核心网控制面接口。NSC支持软硬件解耦合和软件可配置功能。
NSC，用于通过回传网络将收到的DSC和/或LSC的信息传输给核心网。
也就是说，在连接管理方面，NSC负责终结MESH接入网、蜂窝接入网到核心网的控制面连接。
可选的，网络层安全方面，NSC负责对DSC和LSC进行身份验证并建立安全隧道。
具体的，NSC可以对DSC和/或LSC进行身份验证，并在验证通过后在DSC和/或LSC 之间，建立经过回传网络的用于传输数据的安全隧道。
比如NSC与DSC、LSC通过证书机制实现身份认证，并建立IPsec安全通道，保证Me1和C1接口的安全性。
可选的，NSC还可以在业务层(Service)和身份层(identity)，对与DSC连接的EP和特定接入设备进行管理。
可选的，负责对从MESH接入网和蜂窝接入网收到的控制面信令进行处理，包括EP，Device的身份验证，对EP关联的设备类型和服务类型验证与激活过程，为Device设备激活到特定外部网络的会话等。
比如NSC负责对EP的状态信息进行管理，包括跟踪管理(EP当前接入的“簇”信息)，会话管理(例如EP当前激活的业务)，身份管理(例如EP签约的设备类型和服务类型)。
在实施中，NSC属于中心式控制单元，而LSC和DSC都属于分布式控制单元。
可选的，在管理方面，LSC和DSC负责对本地的，时延要求高的功能进行控制。而NSC负责对全局性的，对时延要求不高，对安全性要求高的功能进行控制。
比如LSC负责“簇成员”管理，保存当前簇成员的信息。包括为簇成员分配临时标识，负责为簇内通信进行无线资源分配，以及对簇内空口帧格式、空口基本参数进行管理。
DSC负责对本地接入网进行管理，包括维护本地接入网AP，BS列表，建立维护与AP，BS间可靠连接，可以为AP内通信或BS内通信进行无线资源的分配与协调，负责对从AP和BS接入的Device的链接管理。DSC还可以控制AP和BS用户面数据转发路径选择，DSC还可以对AP、BS在空口帧结构，帧配置参数，以及AP，BS在MAC层使用的传输方案，以及高层协议栈架构进行配置。
在实施中，核心网本身可以部署一个或多个NSC，且不同NSC之间相互平等。在接入网侧，由于接入网分布式的特点，LSC根据地理区域，以及覆盖或容量提升区域的类型进行部署，每个LSC区域由一个LSC进行控制，不同LSC之间也是相互平等的关系，且不存在层级关系(无论LSC控制宏基站还是LSC控制接入点)。
其中，MESH接入网网络中各簇之间能够相互交叠；
蜂窝接入网中各本地接入网之间能够相互交叠；
本地接入网与簇之间能够相互交叠。
可选的，MESH接入网和蜂窝接入网使用传统蜂窝的专用频率或其他公用公共频率。比如传统蜂窝系统采用专用频率，主用频率被分配给不同运营商，用于特定蜂窝系统，例如CDMS，WCDMA，LTE，TD-LTE采用的频率；除传统蜂窝系统采用的专用频率之外，由多个相同或不同制式无线通信系统共用的频率资源。
如图2B所示，本发明实施例的分布式服务中心节点可以是DSC或其他可以控制和服 务多个末端节点的接入网中心节点。由分布式服务中心对一组末端节点进行计费控制，一个分布式服务中心控制和服务的一组末端节点可以称为一个簇，分布式服务中心节点具有类似“簇头”的功能。一个示例如下图所示，DSC1控制末端节点EP1、EP2、EP3的计费，DSC2控制末端节点EP4、EP5、EP6的计费；DSC1和DSC2的基本计费测量和总体控制来自与核心网。核心网可以是运营商网络，从而实现运营商对分布式网络计费的有效控制。
在实施中，本发明实施例的簇也可以称为组。
本发明实施例的DSC功能实体可以是作为分布式服务中心的头节点。具体的设备可以是能够移动的末端节点，比如手持类末端节点(例如智能手机)，或基站类型设备(例如微型基站)或服务器类设备或分布式服务中心。
本发明实施例的EP可以是能够移动的末端节点，比如手持类末端节点(例如智能手机)，或可穿戴设备(例如智能手环)，或机器类设备(例如传感器)。
本发明实施例的EP可以对核心网不可见，也可以对核心网可见。
本发明实施例分布式服务中心节点可以是DSC或其他可以控制和服务多个末端节点节点的接入网中心节点。由分布式服务中心对一组末端节点进行计费控制，一个分布式服务中心控制和服务的一组末端节点可以称为一个簇，分布式服务中心节点具有类似“簇头”的功能。如图2B所示，末端节点接入一个簇进行工作，DSC1控制末端节点EP1、EP2、EP3，DSC2控制末端节点EP4、EP5、EP6。
图2B中的DSC相当于“簇头”，即头节点，对一组末端节点进行控制管理，可以是一个独立实体，也可以是其中一个末端节点，并且DSC可以不是固定实体，例如一个簇下的不同末端节点可以根据需求在不同时间点担任DSC。末端节点EP的数据传输路由可以不经由DSC，例如直接从数据服务器获取数据或经由其他末端节点中继，DSC可以控制数据路由和进行必要的资源管理。由此可见，在这种分布式网络下，DSC不同于蜂窝网的基站，没有基站的集中调度和精细资源管理，控制力度没有基站大。且不同于蜂窝网中核心网对于所有设备的统一安全性、用户体验等统一控制。
当末端节点初始接入系统时，末端节点EP通过分布式服务中心DSC向鉴权设备发送鉴权请求，鉴权设备从服务器中获得用户的签约信息，然后其在鉴权结束后向DSC发送用户的签约信息。鉴权设备一般位于核心网。对于分布式网络，核心网不对每个末端节点进行管理，末端节点接入后，可以将末端节点的用户签约信息删除。末端节点在DSC之间移动时，核心网不参与管理。
下面结合说明书附图对本发明实施例作进一步详细描述。
如图3所示，本发明实施例一种进行服务质量管理的方法包括：
步骤301、目标头节点确定有末端节点需要从源头节点控制范围移动到目标头节点控制范围；
步骤302、目标头节点从源头节点或从网络侧获取末端节点的用户签约信息；
步骤303、目标头节点在末端节点切换到目标头节点控制范围后，根据末端节点的用户签约信息，对末端节点进行服务质量管理。
其中，本发明实施例的头节点是一个簇的管理节点，可以是分布式服务中心。
本发明实施例的头节点控制范围是指头节点控制的簇的范围，也就是说，该末端节点从属于头节点控制的簇。
可选的，本发明实施例根据末端节点的用户签约信息，对末端节点进行服务质量管理。
这里的服务质量管理包括但不限于下列管理中的部分或全部：
QoS控制(比如用户调度优先级、用户最大签约速率、用户保证速率等)，资源配置，多用户资源协调等。
在实施中，目标头节点需要对末端节点进行接纳判决，如果判决结果为允许接纳，则可以将末端节点切换到目标头节点，否则，不允许将末端节点切换到目标头节点。
接纳判决的方法有很多，比如根据负荷判决，具体的，如果负荷高于设定的负荷门限值，则确定负荷过重，不可以接纳；反之，可以接纳。
需要说明的是，采用负荷判决只是举例说明，其他能够进行判决的方式同样适用本发明实施例。比如可以根据末端节点数量判决，如果当前接入的末端节点数量大于设定的数量门限值，则确定接入末端节点数量过多，不可以接纳；反之，可以接纳。
除了上述方式，本发明实施例在进行接纳判决时还可以通过获取的用户签约信息进行。
具体的，目标头节点从源头节点或从网络侧获取末端节点的用户签约信息之后，根据用户签约信息对末端节点进行的接纳判决，如判决当前簇可提供的资源是否能满足用户保证速率或用户最大签约速率，从而判决是否接纳该用户。
需要说明的是，如果接纳判决不需要用户签约信息，则目标头节点可以在确定允许接纳后，去获取用户签约信息；如果接纳判决需要用户签约信息，则目标头节点在进行接纳判决之前就需要获取用户签约信息。
可选的，目标头节点在收到来自源头节点的包含末端节点的标识后，确定有末端节点需要从源头节点控制范围移动到目标头节点控制范围。
可选的，目标头节点需要从网络侧获取末端节点的用户签约信息时，向网络侧发送包含末端节点的标识的签约信息请求消息，并接收来自网络侧的末端节点的用户签约信息。
在实施中，头节点是簇控制节点，不一定直接为末端节点提供数据传输。在分布式网络中，数据来自本地服务器或通过一跳或多跳进行末端节点之间的端到端通信，末端节点从源DSC移动到目标DSC时，需要与数据服务器或对端末端节点重新建立路由通道。
基于此，为了让目标头节点对接入的末端节点更好地服务，一种可选的方式是：目标 头节点通过获取一些信息，为末端节点进行服务。
具体信息包括但不限于下列中的部分或全部：
末端节点当前承载信息、标识信息、跳数信息和中间节点信息。
下面分别进行介绍。
一、末端节点当前承载信息。
具体的，目标头节点确定有末端节点需要从源头节点控制范围移动到目标头节点控制范围之后，接收来自末端节点或源头节点的末端节点当前承载信息；
目标头节点在末端节点接入目标头节点后，根据末端节点当前承载信息，为末端节点建立对应的承载并配置对应的资源。
其中，根据末端节点当前承载信息，为末端节点建立对应的承载并配置对应的资源。例如目标头节点所管理的簇资源可容纳末端节点所有当前承载的传输，则在目标头节点管理的簇中，为末端节点建立与当前承载一致的承载；如果目标头节点所管理的簇资源只能容纳部分末端节点的当前承载的传输，则在目标头节点管理的簇中，优先为末端节点建立需要保障速率的承载和高优先级承载。
二、标识信息，其中标识信息中包括为末端节点提供服务的数据服务器标识和/或与末端节点通信的对端标识。
具体的，目标头节点确定有末端节点需要从源头节点控制范围移动到目标头节点控制范围之后，接收来自末端节点或源头节点的标识信息；
目标头节点在末端节点接入目标头节点后，根据标识信息为末端节点建立数据路由关系。
其中，根据标识信息为末端节点建立数据路由关系由目标头节点的路由算法确定，例如目标头节点确定数据服务器标识和末端节点标识后，按照最短路径原则或合并考虑资源占用情况，确定中间节点和跳数，从而最终确定数据路由关系。
可选的，末端节点和与末端节点通信的对端标识可以是接入网分配的标识，如特定头节点下的C-RNTI，或IP地址，或MAC地址(MAC位址即硬件位址，用于定义终端端口)。在OSI模型中，第三层网络层负责IP地址，第二层数据链路层则负责MAC位址。
三、标识信息、跳数信息和中间节点信息。其中，标识信息中包括为末端节点提供服务的数据服务器标识和/或与末端节点通信的对端标识。
如果末端节点与对端之间的传输是多跳，目标头节点除了获取标识信息，还需要获取跳数信息和中间节点信息。
具体的，目标头节点确定有末端节点需要从源头节点控制范围移动到目标头节点控制范围之后，接收来自末端节点或源头节点的标识信息、跳数信息和中间节点信息；
目标头节点在末端节点接入目标头节点后，根据标识信息、跳数信息和中间节点信息， 为末端节点建立数据路由关系。
其中，根据标识信息、跳数信息和中间节点信息，为末端节点建立数据路由关系由目标头节点的路由算法确定，具体原则为路径最短原则和/或资源使用率最优原则。
如图4所示，本发明实施例另一种进行服务质量管理的方法包括：
步骤401、源头节点确定有末端节点需要从源头节点控制范围移动到目标头节点控制范围；
步骤402、源头节点将末端节点的用户签约信息发送给目标头节点，以使目标头节点在末端节点切换到目标头节点控制范围后，根据末端节点的用户签约信息，对末端节点进行服务质量管理。
下面列举几个实施例对本发明的方案进行说明。
例一、目标头节点从源头节点获取末端节点用户签约信息。
如图5所示，本发明实施例基于从源头节点获取末端节点用户签约信息进行服务质量管理的方法包括：
步骤1：末端节点通过测量(或其他头节点发现过程)确定需要切换后，向源头节点发起切换请求。
可选的，切换请求中可以携带末端节点期望接入的目标头节点的标识。
步骤2：源头节点在收到切换请求后，向目标头节点发送切换请求。
可选的，切换请求中携带末端节点标识和用户签约信息(如QoS参数等)。
步骤3：目标头节点判决是否能接纳末端节点并为其提供其要求的QoS服务；
如果可以接纳该末端节点，在末端节点上下文中存储签约信息，并向源头节点发送切换应答；否则，向源头节点发送拒绝信息。
步骤4：如果源头节点收到来自目标头节点的切换应答，则向末端节点发送切换应答，其中携带目标头节点标识。
步骤5：末端节点在收到切换应答后，向目标头节点发起切换过程。
例二、目标头节点网络侧获取用户签约信息。
如图6所示，本发明实施例基于从网络侧获取末端节点用户签约信息进行服务质量管理的方法包括：
步骤1：末端节点通过测量(或其他头节点发现过程)确定需要切换后，向源头节点发起切换请求。
可选的，切换请求中可以携带末端节点期望的目标头节点标识。
步骤2：源头节点在收到切换请求后，向目标头节点发送切换请求。
可选的，切换请求中携带末端节点标识。
步骤3：标头节点判决是否能接纳末端节点并为其提供其要求的QoS服务；
如果可以接纳该末端节点，在末端节点上下文中存储签约信息，向源头节点发送切换应答；否则，向源头节点发送拒绝信息。
在实施中，进行接纳判决的方式有很多，一种可行的方式是：根据负荷判决，具体的，如果负荷高于设定的负荷门限值，则确定负荷过重，不可以接纳；反之，可以接纳。
需要说明的是，采用负荷判决只是举例说明，其他能够进行判决的方式同样适用本发明实施例。比如可以根据末端节点数量判决，如果当前接入的末端节点数量大于设定的数量门限值，则确定接入末端节点数量过多，不可以接纳；反之，可以接纳。
步骤4：如果源头节点收到来自目标头节点的切换应答，则向末端节点发送切换应答，其中携带目标头节点标识。
步骤5：末端节点在收到切换应答后，向目标头节点发起切换过程。
步骤6：目标头节点向服务器发送签约信息请求，其中携带用户标识。
步骤7：服务器将用户签约信息发送给目标头节点。
步骤8：目标头节点在对应的末端节点上下文中存储收到的用户签约信息。
需要说明的是：步骤6、步骤7可以在步骤2和步骤3之间；相应的，目标头节点获取用户签约信息后，进入步骤3，并根据用户签约信息进行接纳判决，并根据接纳判决结果确定向源头节点回复应答消息还是拒绝消息。
例三、保证末端节点在移动过程中业务连续性的方法。
如图7所示，本发明实施例保证末端节点在移动过程中业务连续性的方法包括：
实施例三和实施例一可以同步进行，实施例三和实施例二可以同步进行。即在传输用户签约信息的同时向目标头节点通知数据路由和承载的信息。目标头节点在判决接纳后就为末端节点建立数据通道和建立对应承载。
步骤1：源头节点通知目标头节点需要进行切换的末端节点的用户数据服务信息。
用户数据服务信息可以包括下列信息中的部分或全部：
末端节点当前承载信息，以使目标头节点为末端节点建立相应承载和资源配置；
为该末端节点提供服务的数据服务器标识，或与该末端节点通信的对端末端节点标识，以使目标头节点在该末端节点进入其管理的簇后，为该末端节点重新建立数据路由关系。
如果末端节点进行的传输是多跳(即传输过程需要经过多个设备)，用户数据服务信息还可以包括跳数和中间节点信息，以使目标头节点可以正确进行数据路由关系建立。
除了由源头节点通知目标头节点需要进行切换的末端节点的用户数据服务信息，还可以由末端节点向目标头节点发送用户数据服务信息。
在实施中，如果由末端节点向目标头节点发送用户数据服务信息，并且是多跳，则根据不同的路由规则有多个情况：
情况一、多跳透明的，即末端节点只知道对端，这时跳数和中间节点信息由源头节点通知目标头节点。
情况二、末端节点知道完整路径信息，则跳数和中间节点信息由末端节点通知目标头节点。
步骤2：目标头节点根据收到的用户数据服务信息，为该末端节点建立业务承载，并建立数据路由通道。
步骤3：在后续信令交互过程中通知末端节点建立的数据路由通道信息，如告知末端节点下一跳标识或数据服务器标识。
基于同一发明构思，本发明实施例中还提供了一种进行服务质量管理的设备，由于该设备解决问题的原理与本发明实施例进行服务质量管理的方法相似，因此该设备的实施可以参见方法的实施，重复之处不再赘述。
