图 14为本发明实施例提供的又一种***的结构示意图。 实施本发明的方式
图 1中所示为下一代移动通信网络的逻辑架构图。 其中, 用户终端通过本地的无线接入网接入 移动通信网络; 接入节点就是所述接入网的汇聚点, 负责移动用户终端的位置管理、 连接管理和网 关选择等功能; 数据网关是用户终端的访问外部数据网络的网关, 负责用户终端访问报文数据网络 的数据连接管理和数据转发, 同时也是为移动用户提供移动服务的锚点。 策略决策实体负责对某个 用户访问某个报文数据网络的数据接入连接的 QoS与计费的控制规则做决策。
所述下一代移动通信网络对应的实际网络, 可以是 GPRS (通用分组无线业务, General Packet Radio Service ) 网络; 无线接入网络具体可以是 UTRAN (Universal Terrestrial Radio Access Network,通用陆地无线接入网络)、 GERAN( GSM/EDGE无线接入网络, GSM EDGE Radio Access Network ) E-UTRAN (演进通用陆地无线接入网络, Evolved Universal Terrestrial Radio Access Network), Wi ax (Worldwide Interoperability for Microwave Access, 全球微波互联接入)、 CDMA (Code Division Multiple Access, 码分多址)、 WLAN (Wireless Local Area Network, 无线局域网络) 等各种无线技术接入网,接入网的网元是指构成接入网的网络设备,作为举例而非限定, UTRAN/GERAN 的 3GPP接入网的接入网元是节点 B; E-UTRAN 的 3GPP接入网的网元是指 RNS (Radio network subsystem, 无线网络子***), 以及 BSS (Base Station Subsystem, 基站子***); 接入节点可以 是 SGSN(GPRS服务支撑节点, Serving GPRS Support Node)、画 E (移动管理实体, Mobility Maraagement Entity) 和 SGW (服务网关, Serving Gateway) 或者 AGW (接入网关, Access Gateway); 数据网 关可以是 PGW (分组数据网络网关, Packet Data Network Gateway) GGSN (GPRS网关支撑节点, Gateway GPRS Support Node), 移动锚点、 或者 HA (家乡代理, Home Agent )。 策略决策实体可以 是 PCRF (策略和计费规则功能, Policy&Charging Rules Function),
现有技术的服务质量控制技术不够灵活。 例如, 当用户终端处于漫游状态, 数据网关或者 PCRF 位于家乡网络时, 拜访网络无法根据本网的需要为用户终端分配 QoS参数。 又例如, 运营商如果希 望针对用户提供不同的服务质量, 需要对网内的 PCRF或者数据网关的配置进行改动才能实现。
为了能够实现对服务质量参数的灵活控制,本发明实施例提 了一种服务质量参数的处理方法, 如图 2所示, 该方法包括:
S201、 接入节点接收 QoS参数, 并根据策略和接收到的 QoS参数分配自定义 QoS参数; 其中, 上述策略为该接入节点所在的网络的 QoS参数的分配规则, QoS参数可以但不仅限于包括: QCI (QoS分类标识, QoS Class Identifier) ARP (分配和保持优先级, Allocation and Retention Priority) ¾ GBR (保证带宽, Guaranteed Bit Rate), MBR (最大带宽, Maximum Bit Rate), APN (接入点名称, Access Point Name) 的 AMBR (聚合最大带宽), Aggregate Maximum Bit Rate) 、
UE (用户设备, User Equipment) 的 MBR等;
上述 S201的具体实现方式可以是, 从数据网关或源接入节点获取 QoS参数 (该 QoS参数通常携带 在消息中), 并根据所述策略、 用户终端的属性信息以及接收到的 QoS参数', 分配自定义 QoS参数, 上 述用户终端的属性信息包括但不仅限于: IMEI (国际移动设备身份码, International Mobile Equipment Identity) 、 归属地 PLMN (公众陆地移动通信网, Public Land Mobile-communication Network) 、 终端类型、 签约信息、 ARP、 QCI、 当前时间 (本发明实施例中, 当前时间是指本次业务 发起的时间), 和 /或 APN; 作为举例而非限定, 该策略中对漫游用户的 QCI进行了自定义分配, 则接 入节点根据用户终端的属性信息判断该用户终端是漫游用户, 进而根据该策略, 将接收到的 QoS参数 中的 QCI值修改为策略中自定义分配的相应 QCI值;
S202、 上述接入节点将自定义 QoS参数发送给接入网的网元, 具体是将上述分配的自定义 QoS参 数中与接入网 QoS控制相关的参数发送给接入网的网元。 作为举例而非限定, E- UT N的接入网, 其 QoS控制相关的参数为 ARP、 QCI、 UE AMBR、 GBR、 MBR, UTRAN的接入网, 其 QoS控制相关的参数为 ARP、 GBR、 MBR、 丢包率、 时延、 抖动等。
本发明实施例提供的方法, 由于接入节点为用户终端分配的是自定义的 QoS参数, 使得用户终端 所在的接入网可以根据该自定义参数对用户终端进行服务质量控制, 较之现有技术的服务质量参数 控制方法更为灵活。
上述本发明实施例中, 分配自定义参数所依赖的策略可以是接入节点本地配置的, 也可以是接 入节点所在的网络中其他通信设备发送给该接入节点的, 该策略可以由一条或多条组成, 作为举例 而非限定, 可以包括如下策略:
为漫游用户提供优于或劣于非漫游用户的服务质量的策略; '
为不同类型的业务提供不同服务质量的策略;
为不同类型的用户终端提供不同服务质量的策略;
为不同优先级的用户终端提供不同服务质量的策略;
基于不同时间段提供不同服务质量的策略。 ·
如果上述接入节点是移动管理实体或 SGSN, 则移动管理实体或 SGSN在分配自定义 QoS参数以后, 还可以将上述自定义 QoS参数发送给服务网关,以便服务网关根据该自定义 QoS参数进行计费或者 QoS 控制;
如果上述接入节点是服务网关,则服务网关通过移动管理实体或 SGSN将上述自定义 QoS参数发送 给接入网的网元。
可选的, 本发明实施例中, 接入节点还可以将上述自定义参数中与用户终端 QoS控制相关的参数 发送给用户终端, 以便用户终端根据接收到的自定义参数(例如 UEAMBR)接入通信网络。如果接 入节点不向用户终端发送自定义 QoS参数, 则将接收到的 QoS参数发送给用户终端。
本发明实施例提供的方法如果应用在承载更新过程中,则接入节点根据策略获得自定义 QoS参数 之后, 将上述获得的自定义 QoS参数与承载建立过程中分配给接入网的 QoS参数进行比较, 如果比较 结果相同, 表明接入网侧不需要进行承载更新, 则结束接入网的承载更新过程, 不向接入网的网元 发送自定义 QoS参数。
本发明实施例中, 对服务质量参数的处理功能可以由接入节点实现, 当用户终端处于漫游状态 时, 对服务质量参数的处理功能还可以由拜访地的策略决策实体实现。 相应的, 本发明实施例还提 供另外一种服务质量参数处理方法, 如图 3所示, 该方法包括: .
5301、 拜访地网络的策略决策实体接收归属地网络发来的 QoS策略, 并根据策略和接收到的 QoS 策略为接入节点指派映射后的 QoS策略, 所述策略用来描述所述拜访地网络的 QoS参数的分配规则; 其中, S301的具体实现方式可以是,拜访地网络的策略决策实体接收归属地网络发来的 QoS策略, 并根据策略、 用户终端的属性信息、 归属地网络发来的 QoS策略, 对归属地网络发来的 QoS策略进行 修改, 得到映射后的 QoS策略, 例如, 策略中对 QCI进行了自定义配置, 则根据该策略, 将接收到的 QoS策略中关于 QCI的内容需改为自定义的 QCI, 所述用户终端的属性信息为: 用户的国际移动设备身 份码 IMEI、 归属地公众陆地移动通信网 PLMN、 当前时间、服务质量分类标识 QCI、 分配和保持优先级 ARP、 签约信息、 终端类型, 和 /或接入点名称 APN。 。
5302、上述拜访地网络将所述映射后的 QoS策略发送给接入节点, 以便所述接入节点根据接收到 的所述映射后的 QoS策略分配 QoS参数。
下面将结合附图对本发明实施例在实际应用过程中的具体实现方式进行详细的说明。
实施例一
本实施例一为 EPS (演进的分组交换网络, Evolved Packet System) 内的专有承载激活过程中 QoS参数处理方法, 其处理过程如图 4所示, 具体包括如下操作:
如果 EPS中部署了 PCC (策略和计费控制, Policy and Charging Control ) ***, 则执行 S401、 PCRF发起会话更新流程, 发送重授权请求消息给数据网关, 该重授权请求消息中携带 QoS策略, 并执 行 S403; ·
如果 EPS中没有部署 PCC***, 则执行 S402、 数据网关根据配置的 QoS策略指派专有承载的 QoS参 数, 并执行 S404;
5403、 数据网关根据接收到的 QoS策略指派专有承载的 QoS参数, 并执行 S404;
5404、 数据网关发送建立承载请求消息给服务网关, 该建立承载请求消息中携带上述专有承载 的 QoS参数, 并执行 S405, 作为举例而非限定, 该 QoS参数包括 QCI和 ARP, 还可以包括 GBR和 MBR;
5405、 服务网关发送建立承载请求消息给移动管理实体, 该建立承载请求消息中携带上述专有 承载的 QoS参数, 并执行 S406;
5406、 移动管理实体收到建立承载请求消息后, 根据策略和接收到的 QoS参数分配自定义 QoS参 数, 并执行 S407;
其中, 上述策略为移动管理实体所在的网络的 QoS参数分配规则, 该策略可以是移动管理实体 本地配置的, 也可以是 EPS网络中的其他通信设备发送给移动 理实体的;
S406的具体实现方式可以是: 移动管理实体根据用户终端的属性信息、 接收的消息中携带的承 载的 QoS参数, 以及上述策略, 获取自定义 QoS参数, 所述用户终端的属性信息包括但不局限于如 下之一或多项: IMEI、 归属地 PLMN、 当前时间、 APN、 QCI、 ARP、 终端类型、 签约信息;
5407、 移.动管理实体发送承载建立请求消息给接入网的网 ¾, 并发送会话管理请求消息给用户 终端, 该承载建立请求消息中携带专有承载的自定义 QoS参数(该自定义 QoS参数包括 QCI和 ARP, 还可以包括 GBR和 MBR), 以便接入网侧接收到移动管理实体发来的自定义 QoS参数后, 釆用该自定 义 QoS参数进行服务质量控制, 在会话管理请求消息中携带移动管理实体分配的专有承载的自定义 QoS参数(该 QoS参数包括 QCI,还可以包括 GBR和 MBR)或者携带服务网关发来的消息中携带的 QoS 参数, 执行 S408; '
5408、 接入网侧进行无线资源重配置, 建立起该专有承载的无线通道, 执行 S409;
5409、 用户终端通过接入网向移动管理实体回复会话管理响应消息, 执行 S410;
5410、 移动管理实体回复建立承载响应消息给服务网关, 可选的, 该建立承载响应消息中携带 自定义 QoS参数 (该自定义 QoS参数包括 QCI和 ARP, 还可以包括 GBR和 MBR), 以便服务网关基于 该自定义 QoS参数进行计费或者 QoS控制, 执行 S411;
S41 S艮务网关回复建立承载响应消息给数据网关, 该建立承载响应消息中不携带上述自定义 QoS参数, 使得接入网侧和核心网侧使用不同但是协调的 QoS参数进行服务质量控制;
如果部署了 PCC, 还执行 S412、 数据网关回复重授权响应命令给 PCRF。
其中, 接入网是 E-UTRAN的 3GPP接入, 对应的基站为节点 B (eNodeB, Evolved Node B), 数 据网关为 PGW。
另外, 上述处理过程中, 服务网关和数据网关之间通过 GPRS隧道协 & (GTP, GPRS Tunnelling Protocol ) 传递消息, 当接口协议为代理移动 IP (PMIP, Proxy Mobile IP) 时, 服务网关和数据 网关之间的消息(步骤 S404和步骤 S411 )取消,服务网关通过 PCRF发来的重授权请求消息获得 QoS 策略, 并根据该 QoS策略指派专有承载的 QoS参数, 并将该专有承载的 QoS参数携带在发送给移动 管理实体的建立承载请求消息中。
上述指派自定义 QoS参数所依据的策略可以包括一条或多条, 作为举例而非限定, 该策略可以 包括:
针对漫游用户 /非漫游用户建立策略, 以便对漫游用户提供比非漫游用户更好(或者更差)的业 务体验, 或者确保在资源紧张时漫游用户能够优先接通以获得更好的收入。 作为举例而非限定, 这 条策略的具体内容可以是: 如果是漫游用户, 则其流类或者背景类业务的承载 QoS参数中的 QCI值 为自定义值" 101 "; 或者, 如果是漫游用户, 则其 QoS参数中的 ARP值配置为更高的优先级。其中, 移动管理实体根据用户归属 PLMN标识识别用户终端是否为漫游用户, 如桌是漫游用户, 则将服务网 关发来的建立承载请求消息中携带的 QoS参数中相应的参数值修改为自定义值;
针对用户终端所请求业务的不同建立策略, 具体通过 APN或 QCI对请求的业务类型进行识别。 作为举例而非限定, 该策略的具体内容可以是: 为互联网业务配置自定义的 QCI值。 当用户终端请 求的业务是互联网业务时, 将服务网关发来的建立承载请求消息中携带的 QoS参数中的 QCI值修改 为自定义值;
针对用户终端类型建立策略, 以便对不同类型的用户终端提供差异化服务。作为举例而非限定, 这条策略的具体内容可以是: 为智能终端的用户配置 QCI值" 57 ", 为数据卡终端的用户配置 QCI值 "63 "。 其中, 移动管琿实体可以根据 IMEI获知用户终端的类型, 进而根据用户终端类型为用户终 端分配自定义 QoS参数;
针对不同优先级的用户终端建立策略, 以便对不同优先级的用户终端提供差异化的服务。 作为 举例而非限定, 这条策略的具体内容可以是: 为高优先级的用户终端提供更高的带宽, 移动管理实 体可以根据 ARP获知用户终端的优先级, 进而根据用户终端的优先级为用户终端分配自定义 QoS参 数。
基于时间段建立策略, 以保证关键时间段内为用户提供更好的体验, 并达到网络资源的最大化 利用。 作为举例而非限定, 这条策略的内容可以是: 白天高峰时间段内为用户终端请求的背景类业 务配置优先级更低的 ARP值, 例如, 将范围在 [a, b]之间的 ARP值映射为优先级更低的 ARP值 " c ", 应当指出的是, 这只是申请人举例说明的一种配置 ARP值的方法, 本发明策略中对 ARP值的配置方 式不仅限于此; 或者, 晚上空闲时间段为终端请求的交互类业务配置优先级更高的 ARP值。
上述列举了一些策略, 具体由运营商决定, 本发明实施例并不局限于这几个策略。
上述本实施例一也适用于 WiMX/WLAN/CDMA等非 3GPP接入, 由接入节点根据策略指派自定义 QoS, 其处理过程可参照上述处理过程, 这里不再详述。
本发明实施例一提供的承载建立过程中, 由于移动管理实体为接入网侧分配自定义 QoS参数, 使得接入网侧和核心网侧使用不同但是协调的 QoS参数进行服务质量控制, 进而提高了 QoS控制的 灵活性。 实施例二 ·
本实施例二也是一种 EPS内的专有承载激活过程中 QoS参数处理方法, 其与上述实施例一的区 别在于, QoS参数映射功能由服务网关实现。 相应的, 其处理过程与实施例一的处理过程的区别在 于:
