Description

信息、数据发送方法及装置、接入网和系统 技术领域
本发明涉及通信领域，具体而言，涉及一种信息、数据发送方法及装置、接入网和系统。
背景技术
在第四代移动通信技术(4th Generation，简称4G)移动通信系统中，将具有相同服务质量(Quality of Service，简称QoS)要求的数据流聚合成承载，用户面网元比如基站、网关对QoS的处理都是以承载作为最小粒度。图1是相关技术中4G系统的QoS控制系统的示意图，其中，该QoS控制系统涉及的主要网元及主要网元的功能如下：
终端(User Equipment，简称为UE)，主要通过无线空口接入4G网络并获得服务，终端通过空口和基站交互信息，通过非接入层信令(Non-Access-Stratum，简称为NAS)和核心网的移动管理实体交互信息；
基站，负责终端接入网络的空口资源调度以及空口的连接管理；
移动管理实体(Mobility Management Entity，简称为MME)，也即核心网控制面实体，主要负责对用户的鉴权、授权以及签约检查，以保证用户是合法用户；对用户进行移动性管理，包括：位置注册和临时标识分配；维护用户的IDLE(空闲)和CONNECT(连接)状态以及状态迁移；在CONNECT状态下的切换；分组数据网络(Packet Data Network，简称PDN)连接以及承载的维护，包括创建、修改和删除等会话管理的功能；
服务网关(Serving Gateway，简称为SGW)：也即核心网用户面功能实体，主要负责漫游情况下和分组数据网网关(PDN GW，简称为PGW)的交互；对用户IDLE状态下收到的下行数据包进行缓存并通知MME寻呼用户；具有跨基站的用户面锚点以及跨第二代移动通信技术(The 2nd Generation，简称2G)、第三代移动通信技术(The 3rd Generation，简称 3G)、4G移动性的用户面锚点等功能；
分组数据网网关(PDN GW，简称为PGW)，也即核心网用户面功能实体，是终端接入PDN网络的接入点，负责分配用户IP地址，网络触发的承载建立、修改和删除，还具有QoS控制计费等功能，是用户在第三代合作伙伴计划(3rd Generation Partnership Project，简称3GPP)系统内以及和非3GPP系统之间切换的锚点，从而保证IP地址不变，以保证业务连续性；
策略控制实体(Policy and Charging Rules Function，简称为PCRF)，也即策略与计费规则功能单元，负责对无线承载的QoS策略控制以及计费策略控制。
4G QoS参数包括：QoS类别标识(QoS Class Identifier，简称QCI)和分配和保留优先级(Allocation and Retention Priority，简称ARP)，QoS参数可以唯一标识一个承载。QCI是一个标准化标识，每个QCI都对应一组QoS参数，包括：承载类型保证速率(Guaranteed Bit Rate，简称GBR)或non GBR、优先级(priority)、延迟要求(Packet Delay Budget)以及丢包率(Packet Error Loss Rate)等参数。ARP标识用于当过负荷的时候，指示本承载被删除或保留的优先级。
针对non GBR承载，QoS参数还包括：聚合最大比特率(Aggregate Maximum Bit Rate，简称AMBR)。AMBR包括：承载聚合最大比特率(UE的所有non GBR，简称UE-AMBR)和APN-AMBR(用户在APN(Access Point Name，接入点名字)上对应的non GBR承载聚合最大比特率)。
4G系统QoS方案中，在建立、修改承载的时候，可以通过QoS参数指示承载的QoS要求；空口上无线承载、S1接口承载以及S5/S8接口承载分别是1:1:1映射；S1接口和S5/S8接口上的承载采用分段的GTP-U(GPRS Tunnelling Protocol for the user plane，用户层面的GPRS隧道协议)隧道的方式传输。
针对GBR承载，QoS参数还包括：MBR(Maximum Bit Rate，最大 比特率)和GBR(Guaranteed Bit Rate，保证比特率)。
但是目前4G系统的QoS方案还存在下述问题：当终端运行一类不可推倒(non-deducible)，也即不能获得稳定业务过滤器的应用时，比如对等网络(Peer to Peer，简称为P2P)业务时，由于网络无法将业务过滤器与承载的绑定关系通知给终端，所以无法让终端获知这类应用的上行QoS参数。目前对这类应用的处理方式是将其放到默认承载上。
目前业界正在研究下一代无线通信系统，图2是相关技术中下一代无线通信系统的架构示意图，为了解决non-deducible业务的上行QoS问题，引入了反射(Reflective)QoS机制。在UE接入网络的过程中，UE和网络协商，网络根据网络策略、UE的能力等因素决定是否对UE接入网络后访问业务的上行数据采用Reflective QoS。也就是说这个UE的所有上行数据都将采用Reflective QoS机制。所谓Reflective QoS机制，就是对于上下行的对应业务，上行业务数据采用与下行业务数据相同的QoS。
然而这种方法会存在如下问题：
(1)目前的QoS方案中存在默认承载(default bearer)概念，并且default bearer允许没有TFT(即通配)，即default bearer上下行可以通配。因此当Reflective QoS授权后，上行数据可以在default bearer上发送，或是根据Reflective QoS授权在对应的下行数据的承载上发送。因此UE无法确定具体在哪个承载上发送数据。
(2)目前的QoS方案中，允许应用的上下行数据采用不同的QoS(即上下行数据分配通过不同的QoS的上下行承载来发送)。此时，由于又激活的Reflective QoS，那么UE将无法决定是采用发送下行数据QoS(即承载)发送上行数据，还是采用另外一个专门的上行承载来发送上行数据。
针对相关技术中的上述技术问题，目前尚未提出有效的解决方案。

为了更好地理解本发明，以下结合优选的实施例对本发明做进一步解释。
本发明提供了一种优选的信息发送方法，具体可以为一种服务质量的控制中为应用进行QoS授权和保障的方法。
优选实施例1
在下一代无线通信系统中，终端接入网络，进行认证为会建立协议数据单元(Protocol Data Unit，PDU)会话(PDU会话类似于EPS系统中的PDN连接)后，网络决定激活Reflective QoS。在本优选实施例中，AN 和UP之间是存在PDU flow的。并且以无线承载粒度通知UE是否激活Reflective QoS。图5是根据本发明优选实施例1提供的信息发送方法的流程示意图，如图5所示，主要包括以下的步骤：
步骤S501，UE和网络建立PDU会话。可选地，UE在PDU会话建立请求消息中会携带支持Reflective QoS的能力指示，网络会根据自身的能力在会话建立应答消息中携带支持Reflective QoS的能力指示。若没有Reflective QoS能力协商过程，则假定在下一代无线通信系统中，总是假定UE和网络支持Reflective QoS。
步骤S502，策略功能(Policy Function)进行策略决策，制定策略规则(如策略控制和计费(Policy Control Charging，简称PCC)规则)，在策略规则中携带应用标识，QoS参数，其中QoS参数中包含有优先级Priority，传输特征Delivery characteristic,网络行为Network behavior,最大速率Maximum bitrate、需求速率Required bitrate和Reflective QoS Indication。其中Priority用于网络资源的接纳，即表示接入网和/或核心网在进行资源接纳和资源管理时如何对相应的业务数据进行处理，Delivery characteristic表示如何对数据包进行转发处理，包括时延、丢包率等因此。Delivery characteristic通常用一个指标值标识，如QCI。Network behaviour表示当网络无法满足授权的QoS表示的QoS目标时预期的处理。Reflective QoS Indication表示授权对数据执行Reflective QoS机制。其中network behavior可选。
步骤S503，Policy Function向CP提供决策后的策略规则。
步骤S504，CP向Policy Function返回确认消息。
步骤S505，CP向UP提供策略规则。
步骤S506，UP保存后，返回确认消息。
步骤S507，CP执行PDU flow绑定，即CP判断当前是否具有和策略规则相同QoS参数的PDU Flow。即Priority、Delivery characteristic和Reflective QoS Indication取值相同，或Priority和Network behavior和 Reflective QoS Indication取值相同、Delivery characteristic、Network behavior和Reflective QoS Indication取值相同或Priority、Delivery characteristic、Network behavior和Reflective QoS Indication取值相同的PDU flow。若没有，在CP决定执行PDU flow创建流程；否则CP决定执行PDU flow修改流程。
步骤S508，CP向UP请求建立或修改PDU flow，携带PDU flow id，QoS参数。若请求建立PDU flow，则CP分配新的PDU flow id。若请求修改PDU flow，则CP选择要绑定到的那个PDU flow的PDU flow Id。QoS参数携带Priority、Delivery characteristic、Network behavior(可选)和Reflective QoS Indication。此外QoS参数中的Maximum bitrate和Required bitrate为绑定到这个PDU flow的策略规则中的Maximum bitrate和Required bitrate的累加。
步骤S509，UP返回确认消息。若是创建PDU flow，则UP返回UP address和UP TEID。
步骤S510，CP向AN发送PDU flow创建或修改消息，携带PDU flow Id，QoS参数，UP address和UP TEID。
步骤S511，AN执行无线承载创建或修改流程，向UE发送的消息中携带PDU flow id，QoS参数以及用于封装用户面数据的无线承载标识。在无线承载修改流程中，Reflective QoS Indication，无线承载标识可不发送若无线承载标识没有修改的话，因为在建立的过程中已提供过。可选地，AN在执行无线承载创建或修改的过程中，可以将UE的多个PDU会话的具有相同QoS的PDU flow汇聚承载一个无线承载。所谓相同的QoS，即Priority、Delivery characteristic和Reflective QoS Indication取值相同，或Priority和Network behavior和Reflective QoS Indication取值相同、Delivery characteristic、Network behavior和Reflective QoS Indication取值相同或Priority、Delivery characteristic、Network behavior和Reflective QoS Indication取值相同的PDU flow。
步骤S512，AN向CP返回确认消息，消息中携带AN地址(Address)和AN TEID。
步骤S513，CP向UP发送PDU flow对应的PDU flow id，AN address和AN TEID。
通过上述流程，创建或修改了一个无线承载，并且所有绑定到这个无线承载的策略规则(即QoS策略)都是执行Reflective QoS，即这个无线承载是激活Reflective QoS。当UP接收到下行数据后，采用AN提供的Address和TEID封装下行数据发送给AN，AN接收到下行数据后，去处UP的封装后，才采用无线承载标识封装下行数据，当UE接收到AN采用该无线承载的无线承载标识封装的下行数据包时，对应的上行数据都将执行Reflective QoS，即都采用下行数据相同的QoS发送上行数据(譬如采用同一个无线承载发送上行数据)。
优选实施例2
在下一代无线通信系统中，终端接入网络，进行认证为会建立协议数据单元(Protocol Data Unit，PDU)会话(PDU会话类似于EPS系统中的PDN连接)后，网络决定激活Reflective QoS。在本优选实施例中，AN和UP之间不存在PDU flow的。并且以无线承载粒度通知UE是否激活Reflective QoS。图6是根据本发明优选实施例2提供的信息发送方法的流程示意图，如图6所示，主要包括以下的步骤：
步骤S601，UE和网络建立PDU会话。可选地，UE在PDU会话建立请求消息中会携带支持Reflective QoS的能力指示，网络会根据自身的能力在会话建立应答消息中携带支持Reflective QoS的能力指示。若没有Reflective QoS能力协商过程，则假定在下一代无线通信系统中，总是假定UE和网络支持Reflective QoS。
步骤S602，策略功能Policy Function进行策略决策，制定策略规则(如PCC规则)，在策略规则中携带应用标识，QoS参数，其中QoS参数中包含有优先级Priority，传输特征Delivery characteristic,网络行为Network  behavior,最大速率Maximum bitrate、需求速率Required bitrate和Reflective QoS Indication。其中Priority用于网络资源的接纳，即表示接入网和/或核心网在进行资源接纳和资源管理时如何对相应的业务数据进行处理，Delivery characteristic表示如何对数据包进行转发处理，包括时延、丢包率等因此。Delivery characteristic通常用一个指标值标识，如QCI。Network behaviour表示当网络无法满足授权的QoS表示的QoS目标时预期的处理。Reflective QoS Indication表示授权对数据执行Reflective QoS机制。其中network behavior可选。
步骤S603，Policy Function向CP提供决策后的策略规则。
步骤S604，CP向Policy Function返回确认消息。
步骤S605，CP向UP提供策略规则。
步骤S606，UP保存后，返回确认消息。
步骤S607，CP向AN提供策略规则中的QoS策略。
步骤S608，AN执行无线承载绑定，即AN判断当前是否具有和策略规则相同QoS参数的无线承载。即Priority、Delivery characteristic和Reflective QoS Indication取值相同，或Priority和Network behavior和Reflective QoS Indication取值相同、Delivery characteristic、Network behavior和Reflective QoS Indication取值相同或Priority、Delivery characteristic、Network behavior和Reflective QoS Indication取值相同的PDU flow(承载)。若没有，在AN决定执行无线承载的创建流程；否则AN决定执行无线承载的修改流程。
步骤S609，AN执行无线PDU flow创建或修改流程，向UE发送的消息中携带PDU flow id，QoS参数以及用于封装用户面数据的无线承载标识。在无线承载修改流程中，Reflective QoS Indication，无线承载标识可不发送若无线承载标识没有修改的话，因为在建立的过程中已提供过。可选地，AN在执行无线承载创建或修改的过程中，可以将UE的多个PDU会话的具有相同QoS的PDU flow汇聚承载一个无线承载。所谓相同的 QoS，即Priority、Delivery characteristic和Reflective QoS Indication取值相同，或Priority和Network behavior和Reflective QoS Indication取值相同、Delivery characteristic、Network behavior和Reflective QoS Indication取值相同或Priority、Delivery characteristic、Network behavior和Reflective QoS Indication取值相同的PDU flow。
步骤S610，AN向UP返回确认消息。
通过上述流程，创建或修改了一个无线承载，并且所有绑定到这个无线承载的策略规则都是执行Reflective QoS，即这个无线承载是激活Reflective QoS。当AN接收到该应用下行数据后，AN会采用无线承载标识进行封装。UE接收到AN用承载标识封装的下行数据包时，对应的上行数据都将执行Reflective QoS，即采用下行数据相同的QoS发送上行数据(譬如采用同一个无线承载发送上行数据)。
优选实施例3
在下一代无线通信系统中，终端接入网络，进行认证为会建立协议数据单元(Protocol Data Unit，PDU)会话(PDU会话类似于EPS系统中的PDN连接)后，网络决定激活Reflective QoS。在本优选实施例中，AN和UP之间是存在PDU flow的。并且以流粒度通知UE是否激活Reflective QoS。图7是根据本发明优选实施例3提供的信息发送方法的流程示意图，如图7所示，主要包括以下的步骤：
步骤S701，UE和网络建立PDU会话。可选地，UE在PDU会话建立请求消息中会携带支持Reflective QoS的能力指示，网络会根据自身的能力在会话建立应答消息中携带支持Reflective QoS的能力指示。若没有Reflective QoS能力协商过程，则假定在下一代无线通信系统中，总是假定UE和网络支持Reflective QoS。
步骤S702，策略功能Policy Function进行策略决策，制定策略规则(如PCC规则)，在策略规则中携带应用标识，Flow Id(可选),QoS参数，其中QoS参数中包含有优先级Priority，传输特征Delivery characteristic,网 络行为Network behavior,最大速率Maximum bitrate、需求速率Required bitrate和Reflective QoS Indication。其中Priority用于网络资源的接纳，即表示接入网和/或核心网在进行资源接纳和资源管理时如何对相应的业务数据进行处理，Delivery characteristic表示如何对数据包进行转发处理，包括时延、丢包率等因此。Delivery characteristic通常用一个指标值标识，如QCI。Network behaviour表示当网络无法满足授权的QoS表示的QoS目标时预期的处理。Reflective QoS Indication表示授权对数据执行Reflective QoS机制。其中network behavior可选。
步骤S703，Policy Function向CP提供决策后的策略规则。
步骤S704，CP向Policy Function返回确认消息，若Policy Function没有分配Flow Id，那么CP会分配Flow ID，并返回给Policy Function。
步骤S705，CP向UP提供策略规则。
步骤S706，UP保存后，返回确认消息。
步骤S707，CP向AN提供策略规则。
步骤S708，AN执行接纳控制。
步骤S709，AN与UE交互，执行资源预留，创建或修改无线承载，AN向UE发送请求消息，携带Flow Id,QoS参数等。可选地，AN在无线承载创建或修改的过程中，具有相同QoS的策略规则绑定到同一个无线承载。可以将UE的多个PDU会话的具有相同QoS的PDU flow汇聚承载一个无线承载。这里所谓相同的QoS，即Priority和Delivery characteristic取值相同，或Priority和Network behavior取值相同、Delivery characteristic和Network behavior取值相同或Priority、Delivery characteristic和Network behavior取值相同。Reflective QoS Indication可以不同。
步骤S710，AN向UP返回确认消息。
通过上述流程，在创建或修改了一个无线承载的过程中，网络向UE通知了需要执行Reflective QoS的应用的下行数据包的封装标识Flow Id。当UP收到下行数据后，采用应用标识检测出对应的下行数据时，UP会 采用Flow Id对下行数据进行封装，当UE收到封装了Flow ID的下行数据后，UE判断该Flow ID激活了Reflective QoS，因此UE对对应的上行数据都将执行Reflective QoS，即采用与下行数据采用的QoS相同的QoS发送上行数据(譬如采用同一个无线承载发送上行数据)。
通过以上的实施方式的描述，本领域的技术人员可以清楚地了解到根据上述实施例的方法可借助软件加必需的通用硬件平台的方式来实现，当然也可以通过硬件，但很多情况下前者是更佳的实施方式。基于这样的理解，本发明的技术方案本质上或者说对现有技术做出贡献的部分可以以软件产品的形式体现出来，该计算机软件产品存储在一个存储介质(如ROM/RAM、磁碟、光盘)中，包括若干指令用以使得一台终端设备(可以是手机，计算机，服务器，或者网络设备等)执行本发明各个实施例所述的方法。
