Description

一种数据发送的方法和装置 本申请要求于 2011 年 09 月 28 日提交中国专利局、 申请号为 201110302159.5、发明名称为"一种数据发送的方法和装置 "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 本发明涉及无线通讯技术领域, 尤其涉及一种数据发送的方法和装 置
背景技术 在固网和移动网相融合的架构中, PCRF(Policy and Charging
Rules Function , 策略和计费规则功能)会将需要建立的承载的 QoS(Quality of service , 服务质量)参数(例如带宽等)通过 S9a接口 传递给 BPCF(broadband policy control function, 宽带策略控制功能), BPCF将从 S9a接口获得的 QoS参数传递给 BNG(Broadband network gateway, 宽带网络网关), 并指导 BNG对数据流进行带宽处理。
S1 切换过程中, 非直接切换的转发数据流是一个源基站到目标 基站的转发数据流,移动网络和固网之间没有办法针对这个转发数据 流做一个 QoS控制和协商。 对于固网节点 BNG来说, 这个转发数据 流是一个事先未知的流, 但是这个流有着和其他从 PDN GW ( Packet Data Network Gateway , 分组数据网络网关)正常下来的 EPC流相同 的外部 IP 流描述特征 (例如同样的外层 IP 地址, 同样的 DSCP(Differentiated Service Code Point, 差分服务点码)值) 。 其他从 PDN GW正常下来的 EPC(Enhanced Packet Core , 演进分组核心网) 流是和一定的 EPS (Enhanced Packet System,演进的分组系统) 载所 绑定的, 这个承载的建立是受 PCRF控制的。 也就是说这个流在家庭 基站固网接入的场景下是有 QoS的控制的, BNG知道给这个流或者 流的集合分配多大的带宽。
当有较多的转发数据出现的时候, 原来的从 PDN G W正常下发的 GBR数据可能仍会受到冲击和影响, 影响用户体验。
发明内容 本发明的实施例提供一种数据发送的方法和装置, 能够保证
PDN GW下发的 GBR数据的可靠传输, 提升用户体验。
一方面, 提供一种数据发送的方法, 包括:
通信设备设置转发数据的规定差分服务点码值,所述转发数据的 差分服务点码值与非转发数据的差分服务点码值不同;
所述通信设备发送所述设置了规定差分服务点码值的转发数据。 一方面, 提供一种数据发送的方法, 包括:
通信设备接收源基站发送的转发数据,所述转发数据被所述源基 站或传输路径上的其他网络设备设置了差分服务点码值,所述通信设 备根据所述接收到的转发数据的差分服务点码值,设置转发数据的差 分服务点码值, 并向目标基站发送所述转发数据; 及
所述通信设备接收分组数据网络网关下发的非转发数据,设置所 述非转发数据的差分服务点码值, 向目标基站发送所述非转发数据; 其中,所述转发数据的差分服务点码值与非转发数据的差分服务 点码值不同。
一方面, 提供一种数据发送的装置, 包括:
设置单元, 用于设置转发数据的规定差分服务点码 DSCP值, 所 述转发数据的 DSCP值与非转发数据的 DSCP值不同;

一方面, 提供一种数据发送的装置, 包括:

所述接收单元用于接收分组数据网络网关下发的非转发数据; 所述设置单元用于设置所述接收单元接收的非转发数据的差分 服务点码值;
所述发送单元用于向目标基站发送所述设置单元设置后的非转 发数据;
其中,所述设置单元设置的转发数据的差分服务点码值与所述设 置单元设置的非转发数据的差分服务点码值不同。 釆用上述技术方案后, 本发明数据发送的方法和装置, 由于转发 数据的 DSCP值被设置, 转发数据的 DSCP值与非转发数据的 DSCP 值不同, 能够在数据的发送过程中, 便于固网节点例如 BNG 识别出 需要保证端到端服务质量的 GBR数据,避免转发数据与非转发数据竟 争固网资源, 因而, 可消除转发数据对非转发数据, 即 PDN GW下发 数据的影响, 即能够保证 PDN GW下发的 GBR数据的可靠传输, 提 升用户体验。
附图说明 为了更清楚地说明本发明实施例或现有技术中的技术方案,下面将对 实施例或现有技术描述中所需要使用的附图作简单地介绍, 显而易见地, 下面描述中的附图仅仅是本发明的一些实施例 ,对于本领域普通技术人员 来讲, 在不付出创造性劳动的前提下, 还可以根据这些附图获得其他的附 图。
图 1为本发明数据发送方法一个实施例的流程图;
图 2为本发明数据转发装置一个实施例的结构框图;
图 3为本发明数据转发装置另一个实施例的结构框图; 图 4为本发明数据转发装置另一实施例的结构框图。
具体实施方式 为了使本发明的目的、技术方案和优点更加清楚, 下面将结合附 图对本发明作进一步地详细描述, 显然, 所描述的实施例仅仅是本发 明一部份实施例, 而不是全部的实施例。 基于本发明中的实施例, 本 领域普通技术人员在没有做出创造性劳动前提下所获得的所有其它 实施例, 都属于本发明保护的范围。
由于从 PDN GW正常下来的 EPC流有端到端的 QoS授权控制, 而非直接转发数据流没有端到端的 QoS授权控制, 属于突发数据流, 这就使得当有较多的非直接转发数据出现的时候,这些非直接转发的 数据流在占用固网资源上和从 PDN GW正常下来的 EPC流可能会进 行不合理竟争, 占用一部分资源, 进而导致原来的从 PDN GW正常 下发的数据流可占用的资源减少, 即, 会对从 PDN GW正常下发的 数据造成冲击和影响。 特别是, 在这样的场景下, 非直接转发数据可 能对终端的 GBR非转发数据产生带宽的竟争, 也可能对同一个基站 下的其他终端的 GBR非转发数据产生带宽的竟争, 因而会使得用户 的感受变差, 例如瞬间出现视屏的马赛克, 甚至中断等。
SGW ( Serving Gateway, 服务网关) 并不区分非直接转发数据 和从 PDN GW正常下发的数据, 而只是根据所对应承载的 QCI(QoS Class Identifier, QoS类别标识)的值来给下行数据设置 DSCP值。 因 而, 当有较多的转发数据出现的时候, 原来的从 PDN GW正常下发 的 GBR数据可能仍会受到冲击和影响, 影响用户体验。
在固网移动网融合的架构中, 在 UE ( User Equipment, 用户设 备) 从原小区进入到目标小区的过程中, UE会有一部分转发数据需 要从原小区对应的源基站传送至目标小区对应的目标基站,以便由目 标基站基于转发数据继续为该 UE提供相应服务。 同时, 该 UE也会 接收到从 PDN GW下发的非转发数据。
需要指出的是, 在本说明书中, 提及 "非转发数据" 均指从 PDN GW正常下发的 GBR数据。
转发数据包括非直接转发的转发数据和直接转发的转发数据,直 接转发的转发数据是指由源基站直接转发给目标基站的转发数据,非 直接转发的转发数据是指源基站不是直接转发给目标基站,而是经由 传输路径上的至少一个中间实体而转发给目标基站的转发数据。
同时需指出, 下文所提及的转发数据均为非直接转发的转发数 据。
同时指出, 若出现 A向 B发送…类似的描述, 可意为 A直接向 B发送, 或意为 A先发送给 C, 再由 C发送给 B , 即可表示 A直接 发送 B , 或表示经由一或多个中间实体而最终发送给 B。 类似地, A 接收 B发送的…之类的描述也可有相同的解释。
图 1为本发明数据发送方法一个实施例的流程图, 如图 1所示, 包括:
511 , 设置转发数据的规定差分服务点码 DSCP值, 所述转发数 据的 DSCP值与非转发数据的 DSCP值不同;
512 , 发送所述设置了规定差分服务点码值的转发数据。
其中, 所述设置转发数据的规定差分服务点码 DSCP值包括: 设置转发数据的 DSCP值为 non-GBR(non-Guaranteed Bit Rate , 非保证比特速率)承载对应的 DSCP值; 或者设置转发数据的 DSCP 值为其他不占用 GBR带宽的 DSCP值, 这个 DSCP值可能导致固网 节点对对应数据包的特殊处理(例如, 和所有其他数据竟争带宽, 不 保证带宽等 ); 或者设置转发数据的 DSCP值为比所述非转发数据更 低优先级的 DSCP值,低优先级的 DSCP值对应固网节点对这些数据 包低优先级的处理, 从而传输速率得不到保证, 也不会和 GBR数据 竟争固网资源。
本发明实施例提供的数据发送的方法, 由于转发数据的 DSCP 值被设置, 转发数据的 DSCP值与非转发数据的 DSCP值不同, 能够 在数据的发送过程中,便于固网节点例如 BNG识别出需要保证端到 端服务质量的 GBR数据,避免转发数据与非转发数据竟争固网资源 , 因而, 可消除转发数据对非转发数据, 即 PDN GW下发数据的影响, 即能够保证 PDN GW下发的 GBR数据的可靠传输, 提升用户体验。 指出的是, 本发明数据发送的方法实施例中的执行主体,视具体 情况而定, 可为 SGW, 源基站、 家庭基站、 演进家庭基站等, 这些 执行主体都在本发明的保护范围之内。
下面以执行主体为目标 SGW为例来说明, 本实施例可以包括: 目标 SGW接收源基站发送的转发数据;
目标 SGW根据转发数据 TEID ( Tunnel End Point Identifier, 隧道 端点标识)和非转发数据 TEID的不同, 区分相同 EPS承载上的转发 数据和非转发数据。 目标 SGW 设置转发数据的规定差分服务点码 DSCP值, 所述转发数据的 DSCP值与非转发数据的 DSCP值不同; 例如, 设置转发数据的 DSCP值为 non-GBR承载对应的 DSCP值; 或者设置转发数据的 DSCP值为其他不占用 GBR带宽的 DSCP值, 这个 DSCP值可能导致固网节点对对应数据包的特殊处理(例如, 和 所有其他数据竟争带宽,不保证带宽等);或者设置转发数据的 DSCP 值为比所述非转发数据更低优先级的 DSCP值,低优先级的 DSCP值 对应固网节点对这些数据包低优先级的处理,从而传输速率得不到保 证, 也不会和 GBR数据竟争固网资源;
目标 SGW根据演进的分组系统 EPS承载的服务质量类别标识 QCI值, 设置非转发数据的 DSCP值;
目标 SGW接收所述目标基站发送的指示标识, 所述指示标识指 示所述目标基站为固网宽带接入的家庭基站; 其中, 目标 SGW接收 所述目标基站发送的指示标识可具体为目标 SGW接收所述目标基站 的切换请求消息, 所述切换请求消息中携带有所述指示标识; 或者目 标 SGW接收所述目标基站的入网注册消息, 所述注册消息中携带有 所述指示标识。
目标 SGW将所述指示标识和所述目标基站对应的转发隧道端点 要求 TEID标识或 EPS承载标识进行绑定;
目标 SGW根据设置的转发数据的 DSCP值, 向所述固网宽带接 入的家庭基站发送所述转发数据;
目标 SGW根据设置的非转发数据的 DSCP值, 向所述固网宽带 接入的家庭基站发送所述非转发数据。
本实施例由于设置转发数据的 DSCP值,转发数据的 DSCP值与 非转发数据的 DSCP值不同, 能够在数据的传送的过程中, 以便于固 网节点例如 BNG识别出需要保证端到端服务质量的 GBR数据, 避 免转发数据与非转发数据竟争固网资源。 因而,可能够保证 PDN GW 下发的 GBR数据的可靠传输消除转发数据对非转发数据的影响, 提 升用户体验。 同时, 通过指示标识将目标基站为固网宽带接入的家庭 基站的情况标识出并且与 TEID标识或 EPS承载标识进行绑定,因而, 在接收到转发数据后,可只针对目标基站是固网宽带接入的家庭基站 的切换转发数据进行 DSCP值的例外处理,并向目标基站发送转发数 据, 使得转发数据的 DSCP值特殊处理更具针对性, 即对于其他目标 基站为非固网宽带接入的家庭基站的场景, 关于同一个 EPS承载的 用户数据, SGW并不区分转发数据和非转发数据, 统一根据演进的 分组系统 EPS承载的服务质量类别标识 QCI值, 以相同的规则 /方法 设置同一 EPS承载上非转发数据和转发数据的 DSCP值。 这样, 可 减轻 SGW区分处理的负荷, 也保证了目标基站为非固网宽带接入的 家庭基站的场景下, 转发数据的服务质量, 因为我们通常认为移动网 络的骨干网的带宽是足够的,而移动网络因为借用固定网络资源传输 移动用户数据, 其在固网能够占用的资源是受限的, 需要进行 QoS 授权的。
下面以执行主体为目标 SGW为例来说明, 本实施可以包括: 目标 SGW接收源基站发送的转发数据, 所述转发数据被所述源 基站或传输路径上的其他网络设备设置了 DSCP值,根据所述接收到 的转发数据的差分服务点码值,设置转发数据的差分服务点码值等于 接收到的转发数据的差分服务点码值,并向目标基站发送所述转发数 据, 其中, 所述转发数据的 DSCP值被设置为 non-GBR承载对应的 DSCP值, 或者被设置转发数据的 DSCP值为其他不占用 GBR带宽 的 DSCP值,这个 DSCP值可能导致固网节点对对应数据包的特殊处 理(例如, 和所有其他数据竟争带宽, 不保证带宽等) ; 或者转发数 据的 DSCP值被设置为比所述非转发数据更低优先级的 DSCP值,低 优先级的 DSCP值对应固网节点对这些数据包低优先级的处理,从而 传输速率得不到保证, 也不会和 GBR数据竟争固网资源;
目标 SGW接收分组数据网络网关 PDN GW下发的非转发数据, 其中, 所述转发数据的 DSCP值与非转发数据的 DSCP值不同; 目标 SGW根据演进的分组系统 EPS承载的 QCI值, 设置非转 发数据的 DSCP值;
目标 SGW接收所述目标基站发送的指示标识, 所述指示标识指 示所述目标基站为固网宽带接入的家庭基站; 其中, 目标 SGW接收 所述目标基站发送的指示标识可具体为, 目标 SGW接收所述目标基 站的切换请求消息, 所述切换请求消息中携带有所述指示标识; 或者 目标 SGW接收所述目标基站的入网注册消息, 所述注册消息中携带 有所述指示标识。
目标 SGW将所述指示标识和所述目标基站对应的转发隧道端点 要求 TEID标识或 EPS承载标识进行绑定; 这样一来, 可只将目标基 站是固网宽带接入的家庭基站的场景下的转发数据进行特殊的 DSCP值的处理, 并将此转发数据发给家庭基站, 而避免对目标基站 为宏站的场景下的切换转发数据进行特殊处理,使得转发数据的特殊 处理更具针对性。 减轻了 SGW区分处理的负担, 也保证了目标基站 为非固网宽带接入的家庭基站的场景下, 转发数据的服务质量。
目标 SGW根据所述设置的转发数据的 DSCP值, 向所述固网宽 带接入的家庭基站发送所述转发数据;
目标 SGW根据所述设置的非转发数据的 DSCP值, 向所述固网 宽带接入的家庭基站发送所述非转发数据。
本实施例由于设置转发数据的 DSCP值,转发数据的 DSCP值与 非转发数据的 DSCP值不同, 能够在数据的发送过程中, 区分出转发 数据和非转发数据,且保证转发数据不与非转发数据竟争资源,因而, 可消除转发数据对非转发数据的影响,保证 PDN GW下发的 GBR数 据的可靠传输, 从而提升用户体验。 同时, 通过指示标识将目标基站 为固网宽带接入的家庭基站的情况标识出并且与 TEID标识或 EPS承 载标识进行绑定, 因而, 在接收到转发数据后, 可只将目标基站是固 网宽带接入的家庭基站的场景下的转发数据进行特殊的 DSCP 值的 处理, 并将此转发数据发给家庭基站, 而避免对目标基站为宏站的场 景下的切换转发数据进行特殊处理,使得转发数据的特殊处理更具针 对性。 减轻了 SGW区分处理的负担, 也保证了目标基站为非固网宽 带接入的家庭基站的场景下, 转发数据的服务质量。 为更好的理解本发明,下面以几个具体实施例为例来对本发明进 行进一步说明。 亦须注意, 以下所列举的实施例亦只是本发明的一部 分实施例, 本领域技术人员由本发明所述内容, 可易于想到其他实施 例, 它们都在本发明的范围内。
本发明提供的另一个实施例包括:
在源基站开始向目标基站转发切换过程中的非直接转发的转发 数据中, 源基站将转发数据送至源服务网关, 并继而送至目标服务网 关, 由目标 SGW 对转发数据进行特殊处理, 使得所述转发数据的 DSCP值与非转发数据的 DSCP值不同, 且所述非直接转发的转发数 据不与从分组数据网络网关下发的非转发数据竟争资源。
这种特殊处理包括, 目标 SGW将从转发隧道到来的转发数据的 DSCP值设置成非 GBR承载所对应 DSCP值, 或者设置转发数据的 DSCP值为其他不占用 GBR带宽的 DSCP值, 这个 DSCP值可能导 致固网节点对对应数据包的特殊处理(例如, 和所有其他数据竟争带 宽, 不保证带宽等); 或者设置转发数据的 DSCP值为比所述非转发 数据更低优先级的 DSCP值,低优先级的 DSCP值对应固网节点对这 些数据包低优先级的处理,从而传输速率得不到保证,也不会和 GBR 数据竟争固网资源;
而目标 SGW对于下行用户面数据的处理按照正常的机制进行。 即根据演进的分组系统 EPS承载的服务质量类别标识 QCI值, 设置 非转发数据的 DSCP值。
处理完毕后, 由目标 SGW根据设置的转发数据的 DSCP值, 将 经处理的转发数据下发给目标基站, 进而传送至用户终端上。 同时, 目标 SGW根据设置的非转发数据的 DSCP值, 向所述固网宽带接入 的家庭基站发送所述非转发数据。
釆用上述方法后, 从 SGW下发的转发下行数据, 其进入固网的 DSCP值永远是一个非 GBR属性的 DSCP值, 固网节点在处理 QoS 带宽控制的时候,这些转发数据不会影响到同一个家庭基站下面的终 端的下行 GBR的数据流, 因而, 能够保证 PDN GW下发的 GBR数 据的可靠传输,使得用户终端上不会出现视频的马赛克、中断等问题, 用户体验明显提升。 本发明提供的另一个实施例包括:
在源基站开始向目标基站转发切换过程中的转发数据时,源基站 可先行对所述转发数据进行特殊处理。
这种特殊处理包括,源基站将转发数据的 DSCP值设置成非 GBR 承载所对应 DSCP值或将转发数据的 DSCP值为不占用 GBR带宽的 DSCP值, 例如 DSCP值为 6 , 7 , 8或者 9 , 或者源基站将转发数据 码值。
而目标 SGW对于非转发的下行用户面数据的处理按照正常的机 制进行。 即根据演进的分组系统 EPS承载的服务质量类别标识 QCI 值, 设置非转发数据的 DSCP值。
源基站处理完毕后, 将经处理的转发数据发给源 SGW, 当源 SGW收到非直接转发隧道来的转发数据的时候, 直接保留从源基站 收到的数据包的的 DSCP的值, 传给目标 SGW, 目标 SGW遵从源 SGW收到的包的 DSCP标识, 对 IP包的 DSCP值并不重新设置, 而 是设置转发数据的差分服务点码值等于接收到的转发数据的差分服 务点码值。 同时, 目标 SGW对于非转发下行用户面数据釆用正常的 处理, 即从承载上下文的 QCI值得到 DSCP值, 并对其 IP头打包。 当没有 SGW重定位的 S1切换下, 即目标 SGW和源 SGW相同的情 况下, 由源 SGW进行处理, 即遵从源基站的上述处理, 对转发数据 DSCP值并不重新设置, 同时, 目标 SGW对于非转发下行用户面数 据釆用正常的处理, 即从承载上下文的 QCI值得到 DSCP值, 并对 IP头打包, 设置 IP 包的 DSCP值。
目标 SGW处理完毕后, 根据设置的转发数据的 DSCP值, 将经 处理的转发数据下发给目标基站, 进而传送至用户终端上; 并根据设 置的非转发数据的 DSCP值, 将非转发数据下发给目标基站, 进而传 送至用户终端上。
釆用上述方法后, 对转发数据和非转发数据进行了不同的处理。 从 SGW下发的转发下行数据, 其进入固网的 DSCP值永远是一个非 GBR属性的 DSCP值, 固网节点在处理 QoS带宽控制的时候, 这些 转发数据不会影响到同一个家庭基站下面的终端的下行 GBR的数据 流, 因而, 能够保证 PDN GW下发的 GBR数据的可靠传输, 使得用 户终端上不会出现视频的马赛克、 中断等问题, 用户体验明显提升。
本发明提供的另一个实施例包括:
在源基站开始向目标基站转发切换过程中的转发数据之前,源基 站需向源 MME发送切换请求,在切换请求中表明哪个承载是需要作 切换中的数据转发。 之后由源 MME 将所述切换请求发送给目标 MME, 再由目标 MME送至目标基站。
本实施例中,目标基站在得知自己是通过宽带接入的家庭基站的 条件下, 在切换请求恢复消息中, 带给目 标 MME —个标识 ( indicator ) , 所述标识是标识目标基站是个家庭基站, 而且是通过 宽带接入的。
目标 MME收到此消息后,在创建非直接转发数据隧道请求消息 中, 将上述标识发送给目标 SGW, 这样目标 SGW可以将这个标识 和对应的转发 TEID标识和 EPS承载标识绑定起来。
在源基站开始向目标基站转发切换过程中的非直接转发的转发 数据中, 源基站将非直接转发的转发数据送至源服务网关, 并继而送 至目标 SGW。
目标 SGW接收到自源基站发送过来的转发数据后, 区分目标基 站是通过宽带接入的家庭基站还是其他基站。若目标是通过宽带接入 的家庭基站对应的转发数据流, 则对所述转发数据流进行特殊处理, 使得所述非直接转发的转发数据的 DSCP值与非转发数据的 DSCP值 不同,且所述非直接转发的转发数据不与从分组数据网络网关下发的 非转发数据竟争资源。
这种特殊处理包括, 目标 SGW将从转发隧道到来的转发数据的 DSCP值设置成非 GBR承载所对应 DSCP值或将转发数据的 DSCP 值为不占用 GBR带宽的 DSCP值, 例如 DSCP值为 6 , 7 , 8或者 9 , 或将转发数据的 DSCP 值为比所述非转发数据更低优先级处理的差 分服务点码值。
而目标 SGW对于下行用户面数据的处理按照正常的机制进行。 即根据演进的分组系统 EPS承载的服务质量类别标识 QCI值, 设置 非转发数据的 DSCP值。 目标 SGW处理完毕后, 根据设置的转发数据的 DSCP值, 将经 处理的转发数据下发给目标基站, 进而传送至用户终端上; 并根据设 置的非转发数据的 DSCP值, 将非转发数据下发给目标基站, 进而传 送至用户终端上。
釆用上述方法后, 从 SGW下发的转发下行数据, 其进入固网的 DSCP值永远是一个非 GBR属性的 DSCP值, 固网节点在处理 QoS 带宽控制的时候,这些转发数据不会影响到同一个家庭基站下面的终 端的下行 GBR的数据流, 因而, 能够保证 PDN GW下发的 GBR数 据的可靠传输,使得用户终端上不会出现视频的马赛克、中断等问题, 用户体验明显提升。
本发明提供的另一个实施例包括:
在源基站向目标基站转发切换过程中的转发数据的过程中,当用 户面数据在目标 HeNB GW或 HNB GW上终结, 即目标 HeNB GW 或 HNB GW对所有的用户面数据需要完成两端 GTP的对接时。
在非直接数据转发隧道建立的过程中, HeNB GW能知道区分出 转发数据对应的 TEID和下行用户面数据对应的 TEID, 所以 HeNB GW可以对转发数据的 DSCP值做进一步的特殊处理。
这种特殊处理包括, HeNB GW将从转发隧道到来的转发数据的 DSCP值设置成非 GBR承载所对应 DSCP值或将转发数据的 DSCP 值为不占用 GBR带宽的 DSCP值, 例如 DSCP值为 6 , 7 , 8或者 9。 的差分服务点码值。
而 HeNB GW对于下行用户面数据的处理按照正常的机制进行。 即根据演进的分组系统 EPS承载的服务质量类别标识 QCI值, 设置 非转发数据的 DSCP值。
需要说明的是: 上述实施例只是说明了 HeNB 接入的场景, 对 于 HNB接入的场景,流程类似,只是对 DSCP特殊处理的网关是 HNB GW, 故在此不再赘述。
釆用上述方法后, 从 SGW下发的转发下行数据, 其进入固网的 DSCP值永远是一个非 GBR属性的 DSCP值, 固网节点在处理 QoS 带宽控制的时候,这些转发数据不会影响到同一个家庭基站下面的终 端的下行 GBR的数据流, 因而, 能够保证 PDN GW下发的 GBR数 据的可靠传输,使得用户终端上不会出现视频的马赛克、中断等问题, 用户体验明显提升。
本发明提供的另一个实施例包括:
在上面一实施例的方案中,所述的标识是通过切换回复消息中目 标基站带给 MME的标识。 是在 UE相关的消息中带给 MME的。 事 实上, 因为这个标识是一个基站接入的属性, 标识家庭基站通过宽带 接入 EPC 网络。 而这一属性, 在家庭基站入网的时候就决定了, 这 个属性独立于家庭基站下面终端的接入过程。 所以, 在本实施例中, 这个标识可以通过 HeNB的入网的过程来实现。
在本实施例中,在家庭基站上电入网的时候,执行以下三个步骤: 步骤 1 : 家庭基站获得固网所分配的 IP地址;
步骤 2: 家庭基站和安全网关进行交互, 建立家庭基站和固网之 间的安全隧道;
步骤 3 : 家庭基站向 HNB GW注册。 在这个注册过程中, 家庭 基站将标识家庭基站通过固网接入的标识发送到 HNB GW。 这个标 识和家庭基站的到 HNB GW之间的 SI SCTP 链接绑定。 通过这个 过程, HNB GW/HeNB GW 得知这个 SCTP连接是关于家庭基站宽带 接入的。 HNB GW/HeNB GW/MME 将这个标识和 SI SCTP链接绑 定, 并存储。
在家庭基站上电之后,H(e)NB GW/MME上保存了 SCTP连接 ID 和上述标识的绑定关系。
接收由所述目标基站在上电入网时在注册消息里上报的指示目 标基站是固网宽带接入的家庭基站的标识。
对所述标识和 SCTP链接 ID绑定, 并存储;
在接收到切换请求回复消息之后,判断所述切换请求回复消息所 在的 SCTP链接是否存在于所存储的 SCTP链接标识中;
在所述切换请求回复消息所在的 SCTP 链接存在于所存储的 SCTP链接标识中时, 对所述标识和对应的转发 TEID标识或 EPS承 载标识进行绑定,以在所述非直接转发的转发数据的目标是所述固网 宽带接入的家庭基站时,只向所述固网宽带接入的家庭基站发送所述 非直接转发的转发数据。
当 S1切换到目标家庭基站后, MME在收到切换请求回复之后, MME对比存储的 SCTP连接标识和切换回复消息所在的 SCTP连接 标识, 若切换回复消息所在的 SCTP连接有上述标识, 则 MME在创 建非直接转发数据隧道请求中进一步携带这个标识到目标 SGW。 目 标 SGW将这个标识和目标基站产生的上行数据转发 TEID绑定。
目标 SGW在收到转发数据后, 对转发数据做特殊的 DSCP值特 殊处理。 这种特殊处理包括, 目标 SGW将从转发隧道到来的转发数 据的 DSCP值设置成非 GBR承载所对应 DSCP值或将转发数据的 DSCP值为不占用 GBR带宽的 DSCP值, 例如 DSCP值为 6 , 7 , 8 或者 9 , 或将转发数据的 DSCP值为比所述非转发数据更低优先级处 理的差分服务点码值。
而目标 SGW对于下行用户面数据的处理按照正常的机制进行。 即根据演进的分组系统 EPS承载的服务质量类别标识 QCI值, 设置 非转发数据的 DSCP值。
目标 SGW处理完毕后, 将经处理的转发数据只下发给所述通过 固网接入的家庭基站, 进而传送至该家庭基站下相应的用户终端上。
釆用上述方法后, 从 SGW下发的转发下行数据, 其进入固网的 DSCP值永远是一个非 GBR属性的 DSCP值, 固网节点在处理 QoS 带宽控制的时候,这些转发数据不会影响到同一个家庭基站下面的终 端的下行 GBR的数据流, 因而, 能够保证 PDN GW下发的 GBR数 据的可靠传输,使得用户终端上不会出现视频的马赛克、中断等问题, 用户体验明显提升。
与本发明数据发送的方法相对应,本发明还提供一种数据发送的 装置, 如图 2所示, 包括:
