Description

用于数据传输的方法、 分流点设备、 用户终端及其系统 本申请要求于 2011 年 6 月 30 日提交中国专利局、 申请号为 201110182284.7 ,发明名称为"用于数据传输的方法、 分流点设备、 用户终端 及其系统"的中国专利申请优先权,上述专利的全部内容通过引用结合在本申 请中。 技术领域 本发明涉及通信领域,并且更具体地,涉及通信领域中用于数据传输的方 法、 分流点设备、 用户终端及其系统。
背景技术 随着智能手机的出现,各种数据新业务也应运而生,在此背景下,蜂窝网 络尤其是 3G ( Third Generation ,第三代)网络的移动数据量呈现出爆炸性增 长。 为了减轻 3G网络负载,出现了包括 WiFi ( Wireless Fidelity ,无线保真)分 流、 微蜂窝分流在内的多种分流技术,其中 WiFi分流是运营商最看重的方案, 并已经在运营商中开始大范围的部属。 从 WLAN ( Wireless Local Area Network , 无线局域网 )与诸如 UMTS ( Universal Mobile Telecommunications System ,通用移动通信系统 )网络之类 的移动网络互通方式的角度出发,WiFi分流可以被分为松耦合方式与紧耦合方 式。 松耦合方式是指 WLAN与 3G网络在进行互通时不影响彼此的独立性,在 该情况下的互通只是指 WLAN和 3G网络具有共同的 AAA ( Authentication Authorization and Accounting,认证鉴权与计费)实体加以连接。紧耦合方式是 指将 WLAN视为 3G核心网的一个接入网 ,用户终端不仅可以通过 3G网络的接 入网接入 3G核心网,还可以通过 WLAN接入 3G核心网。 在紧耦合方式下,用户终端与分组网之间交互的数据既可以通过 3G核心 网、 3G接入网和 3G接入网提供的 3G空口进行,也可以通过 3G核心网、 WLAN 接入网和 WLAN接入网提供的 WiFi空口进行,还可以同时通过 3G空口和 WiFi 空口进行。 虽然上面以 WLAN与 3G网络为例说明了紧耦合方式,但是本领域 技术人员可以想到紧耦合方式也可以出现在其他网络架构中 ,例如 WLAN与 LTE ( Long Time Evolution ,长期演进)网络。
在现有技术中 ,由于待发送数据不会在各空口之间进行分配,所以各空口 上传输的上行数据和下行数据彼此没有关联,使得用户终端在各空口上所处的 通信状态只能进行独立地控制。
例如,在 UMTS网络中 , RNC ( Radio Network Controller ,无线网络控制 器)根据用户终端的上下行数据量大小来控制用户终端的 RRC( Radio Resource Control , 无线资源控制 )状态。 用户终端在线时的 RRC状态可以包括 CELL_DCH态、 CELL_FACH态、 CELL_PCH态、 URA_PCH态和 IDLE态。 从 用户终端的耗电量角度考虑,按照 CELL_DCH态、 CELL_FACH态、 CELL_PCH 态、 URA_PCH态和 IDLE态的顺序,用户终端的耗电量不断下降。
再例如,在 WLAN中 ,用户终端根据自己是否有数据发送和 /或接收来独 立控制在 WiFi空口上所处的通信状态。用户终端在线时的 WiFi空口上的状态可 以包括连接态、 空闲态和睡眠态,其中连接态又可以包括发送态和接收态。 当 用户终端关闭 WiFi连接时, WiFi空口上的状态为关闭态。从用户终端的耗电量 角度考虑,按照连接态、 空闲态、 睡眠态和关闭态的顺序,用户终端的耗电量 不断下降。
又例如,在 LTE网络中 ,用户终端根据预测的上下行数据量大小来确定自 己所处的通信状态。 用户终端在 LTE系统中可以进行 DRX ( Discontineous Reception ,不连续接收)状态的判断,使自己处于非 DRX ( NON-DRX )态、 短 DRX ( short DRX )态、 长 DRX ( long DRX )态和 IDLE态之一。 从用户终端 的耗电量角度考虑,按照非 DRX态、 短 DRX态、 长 DRX态和 IDLE态的顺序, 用户终端的耗电量不断下降。
由于现有技术中不对待发送的数据进行空口之间的分配,使得用户终端在 单一空口上的通信状态只能得到独立的管理,彼此之间没有联系。 因此,在用 户终端支持紧耦合方式例如用户终端支持双在线功能的情况下,不能在各空口 之间对待发送的数据进行统一的分配,从而不能对该用户终端在多个空口上的 通信状态进行统一管理,不利于实现节省用户终端的耗电量的目的。 发明内容
本发明实施例提供了用于数据传输的方法、分流点设备、用户终端及其系 统,可以解决待发送数据在多个空口之间独立分配而彼此没有联系的问题,从 而可以将各空口结合在一起管理,有利于对用户终端在多个空口上所处的通信 状态进行统一管理。

下面将结合本发明实施例中的附图 ,对本发明实施例的技术方案进行清 楚、 完整地描述,显然,所描述的实施例是本发明的一部分实施例,而不是全 部实施例。基于本发明中的所述实施例,本领域技术人员在没有做出创造性劳 动的前提下所获得的所有其他实施例,都应属于本发明保护的范围。
首先结合图 1至图 4描述紧耦合方式下网络架构的例子,图 1至图 4只是示例 性的描述, 并不对本发明可应用的场景构成任何限制。 虽然图 1至图 3是以 UMTS网络与 WLAN网络为例描述紧耦合方式下的网络架构,图 4是以 LTE网络 与 WLAN网络为例描述紧耦合方式下的网络架构,其中将 WLAN作为 UMTS或 LTE核心网的接入网 ,但是本发明可应用到的网络架构并不限于 UMTS网络、 LTE网络和 WLAN网络,还可以将本发明应用到其他网络类型构成的紧耦合形 式,例如基于 3GPP ( Third Generation Partnership Project ,第三代合作伙伴计 划)协议的其他网络以及其他接入协议下的接入网络。
在图 1中 ,用户终端( User Equipment , UE )可以通过包括节点 B ( Node B ) 和 RNC的 UTRAN ( UMTS Terrestrial Radio Access Network , UMTS陆地无线接 入网)接入 3G/UMTS核心网。 UE还可以通过包括接入点( Access Point , ΑΡ ) 的 WLAN接入网接入 3G/UMTS核心网,其中 IWU ( Interworking Unit ,互通实 体)用于将 ΑΡ连接到 RNC。 在 3G/UMTS核心网中包括 SGSN ( Serving GPRS Support Node , GPRS服务支持节点)和 GGSN ( Gateway GPRS Support Node , GPRS网关支持节点) b UE通过接入 3G/UMTS核心网,可以进一步接入互联网, 进而接收分组数据服务。
UE向互联网传输的数据无论是通过 UTRAN提供的 UMTS空口还是通过 WLAN提供的 WiFi空口 ,都将到达 RNC ,再由 RNC将数据传输到 3G/UMTS核 心网 ,进而使数据到互联网。 互联网向 UE传输的数据都将经过 3G/UMTS核心 网到达 RNC ,再由 RNC对数据进行分流,既可以通过 UMTS空口向 UE传输, 又可以通过 WiFi空口向 UE传输,还可以同时通过 UMTS空口和 WiFi空口向 UE 传输。 由此可见,在该网络建构下,分流点设备为 RNC。
在图 2中 ,与图 1类似, UE通过 UTRAN和 WLAN连接到 3G/UMTS核心网。 不同的是,当 UE通过 WLAN连接到 3G/UMTS核心网时, WLAN接入网是通过 GIF连接到 SGSN ,而不是像图 1那样通过 IWU连接到 RNC、 然后连接到 SGSN。 在图 2中 ,分流点设备为 SGSN。
在图 3中 ,与图 1类似, UE通过 UTRAN和 WLAN连接到 3G/UMTS核心网。 不同的是,当 UE通过 WLAN连接到 3G/UMTS核心网时, WLAN接入网是通过 WLAN网关和 VGSN连接到 SGSN/GGSN ,而不是像图 1那样通过 IWU连接到 RNC、 再连接到 SGSN。 在图 3中 ,分流点设备为 GGSN。
除了图 1至图 3所示的网络架构的例子之外,在 UMTS网络与 WLAN网络具 有紧耦合形式的情况下, Node B也可以作为分流点设备。
在图 4中 , UE可以通过演进型基站( evolved Node B , eNB )连接到 S-GW ( Serving-Gateway ,服务网关)而接入 LTE核心网。 UE还可以通过 AP连接到 S-GW ( Serving-Gateway ,服务网关)而接入 LTE核心网 ,此时, AP可以直接 连接到 S-GW , 也可以先连接到 eNB再连接到 S-GW。 在 LTE核心网中包括 S-GW、 PDN-GW ( Packet Data Network- Gateway ,分组数据网网关)、 MME ( Mobile Management Entity ,移动管理实体 HSS ( Home Subscriber Server , 家乡用户服务器)、 PCRF ( Policy Charging and Rules Function ,策略和计费规 则功能 AAA服务器等。 UE通过接入 LTE核心网,可以进一步接入 IP网络, 进而接收分组数据服务。
UE向互联网传输的数据无论是通过 LTE网络提供的 LTE空口还是通过
WLAN提供的 WiFi空口 ,都将到达 S-GW ,经由 LTE核心网对数据的转发而使 UE接受分组数据服务。 在该网络建构下,分流点设备为 S-GW。
除了图 4所示的网络架构的例子之外,在 LTE网络与 WLAN网络具有紧耦 合形式的情况下, eNB、 PDN-GW也可以作为分流点设备。
接下来,参考图 5描述根据本发明实施例的用于数据传输的方法 500。
如图 5所示,方法 500包括:
S510:基于预定策略将待向用户终端发送的下行数据分配到第一空口和第 二空口上,其中用户终端通过第一空口经由第一接入网连接到核心网 ,并通过 第二空口经由第二接入网连接到核心网;
S520:通过第一空口向用户终端发送分配到第一空口上的下行数据;
S530:通过第二空口向用户终端发送分配到第二空口上的下行数据。
例如,方法 500可以由诸如 RNC、 SGSN、 GGSN、 S-GW之类的分流点设 备执行。 分流点设备基于预定策略在第一空口和第二空口之间分配下行数据, 使得可以对在第一空口和第二空口上传输的下行数据进行灵活地分配,从而有 利于将第一空口和第二空口上的通信状态联系起来,避免对第一空口和第二空 口独立地进行管理。 因此,通过利用根据本发明实施例的方法,有利于实现对 第一空口和第二空口的统一管理,从而有利于改善用户终端的节能,改善网络 资源的使用效率,并缓解对单一空口造成过大的传输负担。
在 S510中 ,可以通过多种方式在第一空口和第二空口之间分配待向 UE发 送的下行数据。通过分配下行数据,使得在第一空口和第二空口上发送的下行 数据不再是独立分配得到的,因此有利于第一空口和第二空口的通信状态的统 一管理。 下面,详细描述分配下行数据的不同方式。
根据本发明的一个实施例,基于待向用户终端发送的下行数据的服务质量 要求,将服务质量要求超过预定服务质量要求的下行数据分配到第一空口上, 将服务质量要求未超过预定服务质量要求的下行数据分配到第二空口上。
下行数据的服务质量( Quality of Service , QoS )要求可以包括延时、 时延 抖动、 传输带宽等。 无论是在 UMTS网络中还是在 LTE网络中 ,网络侧可以通 过查询分组数据协议上下文( Packet Data Protocol context , PDP context )来得 到 QoS要求。
预定服务质量要求可以是根据网络配置而提前设定的服务质量要求。当下 行数据的服务质量要求超过预定服务质量要求时,该下行数据具有高服务质量 要求,反之,该下行数据具有低服务质量要求。
例如,如果预定服务质量要求与延时有关,例如 0.1秒延时,则在下行数 据要求的延时小于 0.1秒的情况下,该下行数据具有高服务质量要求,将该下 行数据分配到第一空口上;反之,在下行数据要求的延时等于或大于 0.1秒的 情况下,该下行数据具有低服务质量要求,将该下行数据分配到第二空口上。 因此,以服务质量要求是延时为例,可以将对延时敏感的下行数据分配到第一 空口上,将对延时不敏感的下行数据分配到第二空口上。
可以基于待向所述用户终端发送的下行数据所属的业务类型,确定服务质 量要求。举例来说,当下行数据是网页浏览业务时,由于网页浏览业务要求尽 力而为交付即可,因此可以确定该下行数据的服务质量要求低。当下行数据是 在线语音业务时,由于在线语音业务对实时性要求高,因此可以确定该下行数 据的服务质量高。
根据本发明的一个实施例,在通过第二空口传输待向用户终端发送的下行 数据满足下行数据的服务质量要求的情况下,如果通过第二空口传输下行数据 满足下行数据的吞吐量要求,则将下行数据全部分配到第二空口上。
如果在第二空口上传输下行数据同时满足下行数据的服务质量要求和下 行数据的吞吐量要求,则将下行数据都分配到第二空口上。
吞吐量要求可以是指在单位时间内要求传输的数据量大小。数据量大小可 以通过测量缓存器中缓存的数据来得到。
根据本发明的一个实施例,在通过第二空口传输待向用户终端发送的下行 数据的一部分满足该一部分下行数据的服务质量要求和吞吐量要求、而传输下 行数据的另一部分不满足该另一部分下行数据的服务质量要求或吞吐量要求 的情况下,将该一部分下行数据分配到第二空口上,将该另一部分下行数据分 配到第一空口上。
如果下行数据中有一部分适合在第二空口上传输,即第二空口可以同时满 足该部分下行数据的服务质量要求和吞吐量要求,则将这部分下行数据分配到 第二空口上。对于剩下的那部分下行数据而言,第二空口可能不能满足其服务 质量要求,也可能不能满足其吞吐量要求,还可能既不满足其服务质量要求、 又不满足其吞吐量要求,此时,将剩下的这部分下行数据分配到第一空口上。
根据本发明的一个实施例,在通过第二空口传输待向用户终端发送的下行 数据不满足下行数据的服务质量要求的情况下,将下行数据全部分配到第一空 口上。
如果第二空口不满足下行数据的服务质量要求,则无论第一空口是否满足 下行数据的服务质量要求,都将下行数据全部分配到第一空口上。
由此可见,可以根据服务质量要求和吞吐量要求在第一空口和第二空口之 间分配待发送数据,并且在第二空口可满足传输的情况下,优先将数据分配到 第二空口上。 如果第二空口是 WiFi空口 ,那么无论第一空口是 UMTS空口还是 LTE空口 , 由于优先考虑 WiFi传输,可以为 UMTS网络或 LTE网络提供真正的 数据分流,降低 UMTS空口或 LTE空口对应的网络资源的负担。
根据本发明的一个实施例,在不需要向用户终端发送下行数据的情况下, 不将下行数据分配到第一空口和第二空口上。
由于没有向用户终端发送的下行数据,因此在第一空口和第二空口上不分 配下行数据。
根据本发明的一个实施例,在需要与用户终端执行心跳机制过程的情况 下,将保活消息分配到负责监听寻呼消息的第一空口或第二空口上
网络侧与 UE通过相互发送保活消息( keep-alive消息)来执行心跳机制, 此时分流点设备待向 UE发送的下行数据只有 keep-alive消息。 分流点设备可以 将 keep-alive消息分配到负责监听寻呼消息的第一空口或第二空口进行发送, 而在另一空口上则不分配任何下行数据。
根据本发明的一个实施例,在用户终端不能通过第二空口接入第二接入网 的情况下,始终将待向用户终端发送的下行数据分配到第一空口上。
例如,当 UE的第二空口关闭时,或者当 UE的第二空口对应的信道质量迅 速下降时, UE不能再使用第二空口接入第二接入网。 对于网络侧而言, UE的 第二空口不可用 ,此时分流点设备可以将下行数据全部分配到第一空口上。第 一空口可以是 UE始终保持在线的空口。
虽然上面描述了多种将下行数据在第一空口和第二空口之间进行分配的 方式,但是本领域技术人员还可以想到其他分配下行数据的方式。通过基于预 定策略分配下行数据,可以将第一空口和第二空口统一起来进行管理。
在 S520和 S530中 ,分流点设备在第一空口和第二空口之间分配了下行数据 之后,将分配到第一空口上的下行数据通过第一空口向 UE发送,将分配到第 二空口上的下行数据通过第二空口向 UE发送,从而可以实现下行数据的分流 传输。该分流传输不是像现有技术那样独立地进行的,而是通过统一管理分配 之后进行的。 由于统一管理的存在,有可能改善网络传输效率,降低网络传输 负担,优化用户通信体验,并降低通信终端耗电量。
虽然在方法 500中 S530在 S520之后执行,但是 S530也可以在 S520之前执 行,还可以与 S520并发执行。
根据本发明实施例提供的用于数据传输的方法,分流点设备通过基于预定 策略在第一空口和第二空口之间分配下行数据,可以对在第一空口和第二空口 上传输的下行数据进行灵活地分配,从而有利于将第一空口和第二空口上的通 信状态联系起来,避免对第一空口和第二空口独立地进行管理,因此,有利于 实现对第一空口和第二空口的统一管理,从而有利于改善用户终端的节能,改 善网络资源的使用效率,并缓解对单一空口造成过大的传输负担。
下面,参考图 6描述根据本发明实施例的用于数据传输的方法 600。
S610:基于预定策略将待向用户终端发送的下行数据分配到第一空口和第 二空口上,其中用户终端通过第一空口经由第一接入网连接到核心网 ,并通过 第二空口经由第二接入网连接到核心网。 S610与 S510相同。
S640:接收用户终端上报的分别分配到第一空口和第二空口上待向分流点 设备发送的上行数据的吞吐量,其中上行数据的吞吐量由用户终端基于预定策 略将上行数据分配到第一空口和第二空口上之后确定。
UE通过基于预定策略在第一空口和第二空口上分配将发送的上行数据, 可以确定第一空口上的上行数据的吞吐量和第二空口上的上行数据的吞吐量。 UE将它所确定的吞吐量上报给分流点设备,以使分流点设备可以参考上行数 据的吞吐量来确定空口上的通信状态。
UE可以主动向分流点设备上报上行数据的吞吐量,也可以在收到分流点 设备发送的与上行数据的吞吐量有关的查询请求时上报。例如,当第一空口是 UMTS空口时,分流点设备通过向 UE发送查询请求来确定 UE是否有上行数据 需要发送,以在 UE有上行数据需要发送的情况下将 UE迁移到 CELL_FACH态 或 CELL_DCH态。
此外, UE上报上行数据的吞吐量的形式包括直接上报吞吐量,也包括上 报预定时间内的数据量,还包括发送用于指示没有待发送的上行数据的控制消
UE分配上行数据的预定策略将结合图 10进行具体描述。 通过 UE对上行数 据的分配,使得在第一空口和第二空口上发送的上行数据不再是独立分配得到 的,从而有利于第一空口和第二空口的通信状态的统一管理。
虽然在方法 600中 S630在 610之后执行,但是 S630也可以在 S610之前执行, 还可以与 S610并发执行。 S650:基于第一空口上的下行数据的吞吐量和上行数据的吞吐量,确定用 户终端在第一空口上所处的第一通信状态。
分流点设备在 S610中在第一空口和第二空口上分配了下行数据之后,可以 通过分别测量缓存在与第一空口相应的缓存器中的数据和与第二空口相应的 缓存器中的数据,确定第一空口上的下行数据的吞吐量和第二空口上的下行数 据的吞吐量。
分流点设备知道了第一空口上的上行数据和下行数据的吞吐量之后,可以 综合考虑两者的吞吐量,来确定 UE在第一空口上所处的第一通信状态。例如, 当第一空口是 UMTS空口时,确定 UMTS空口上的第一通信状态的方式可以与 现有技术相同。
例如,可以通过将第一空口上的吞吐量与迁移门限进行比较,确定第一通 信状态。当上行数据的吞吐量和下行数据的吞吐量之一达到了状态迁移的门限 时,就可以进行状态迁移。举例来说,假设 CELL_DCH态的迁移门限为 10kbps , 此时,分流点设备确定的下行数据的吞吐量为 12kbps ,上行数据的吞吐量为 lkbps ,即便上行数据的吞吐量没有达到迁移门限,但是由于下行数据的吞吐 量达到了迁移门限, 因此分流点设备确定需要将 UE在第一空口上的第一通信 状态迁移到 CELL_DCH态。
可以对第一通信状态的迁移门限进行不同的设定,也可以采用现有标准中 规定的迁移门限。此外,确定第一通信状态时,还可以根据定时器的定时来判 断。 当然,本领域技术人员还可以想到其他确定第一通信状态的方式。
S660:基于第二空口上的下行数据的吞吐量和上行数据的吞吐量,确定用 户终端在第二空口上所处的第二通信状态。 由于分流点设备知道了第二空口上的上行数据和下行数据的吞吐量,因此 分流点设备可以综合考虑两者的吞吐量,来确定 UE在第二空口上所处的第二 通信状态。
通过将第二空口上的吞吐量与迁移门限进行比较,可以确定第二通信状 态。 当上行数据的吞吐量和下行数据的吞吐量之一达到了状态迁移的门限时, 就可以进行状态迁移。例如,当第二空口是 WiFi空口时,如果上行数据的吞吐 量和下行数据的吞吐量之一不为 0 ,则确定 UE需要迁移到连接态;如果上行数 据的吞吐量和下行数据的吞吐量都为 0 ,则在 WiFi空口不可用的情况下,则确 定 UE迁移到关闭态,在 WiFi空口可用的情况下,确定 UE迁移到空闲态。
第二通信状态的迁移门限可以进行不同的设定,也可以采用现有标准中规 定的迁移门限。
虽然在 S660在 S650之后执行,但是 S660也可以在 S650之前执行,还可以 与 S650并发执行。
根据本发明的一个实施例,在第一空口上的吞吐量和第二空口上的吞吐量 都为零的情况下,如果与数据分流机制相关的信令需要通过第一空口的 RRC 连接传输,则确定用户终端在第一空口上所处的第一通信状态为 CELL_PCH态 或 URA_PCH态,确定用户终端在第二空口上所处的第二通信状态为睡眠态或 关闭态。
数据分流机制可以是 WiFi分流机制,还可以是其他紧耦合形式的网络架构 下的分流机制。 与数据分流机制相关的信令可以是与分配上行数据和 /或下行 数据的策略有关的信令,还可以是本领域技术人员可以想到的在数据分流中需 要使用到的其他信令。 例如,在没有数据需要与 UE进行交互的情况下,如果与 WiFi分流机制相 关的信令需要通过 UMTS的 RRC连接传输,则分流点设备可以确定将 UE在 UMTS空口上的通信状态迁移到 CELL_PCH态或 URA_PCH态,由 UMTS空口监 听 PICH ( Paging Indicator Channel ,寻呼指示信道)以便收听寻呼消息,还可 以监听与 WiFi分流机制相关的信令,从而可以避免后续数据传输可能造成的信 令风暴。 此时,为了降低 UE的耗电量,可以将 UE在 WiFi空口上迁移到睡眠态 或关闭态。
根据本发明的一个实施例,第一空口上的吞吐量和第二空口上的吞吐量都 为零的情况下,如果与数据分流机制相关的信令不需要通过第一空口的 RRC 连接传输,则确定第一通信状态为 IDLE态,确定第二通信状态为空闲态。
例如 ,如果与 WiFi分流机制相关的信令不需要通过 UMTS的 RRC连接传 输,即与 WiFi分流机制相关的信令需要通过 WiFi空口传输,则分流点设备可以 确定将 UE在 UMTS空口上的通信状态迁移到 IDLE态,此时将 UE在 WiFi空口上 的通信状态迁移到空闲态,由 WiFi空口监听寻呼消息,还可以监听与 WiFi分流 机制相关的信令,从而可以避免后续数据传输可能造成的信令风暴。由于此时 UMTS空口上的通信状态耗电量最低,因此同样可以在避免信令风暴的同时降 低 UE的耗电量。
S670:向用户终端通知第一通信状态和第二通信状态,以使用户终端进入 到第一通信状态和第二通信状态中。
分流点设备确定的第一通信状态和第二通信状态之后, 向 UE通知所确定 的通信状态,以使 UE进行状态迁移。 分流点设备可以自己向 UE发送状态迁移 的信令来通知通信状态,也可以通过指示其他网络设备向 UE发送状态迁移的 信令来通知通信状态。
S620:通过第一空口向用户终端发送分配到第一空口上的下行数据。 S630:通过第二空口向用户终端发送分配到第二空口上的下行数据。 S620和 S630只要在 S610之后执行即可, 而不受图 6所示的执行顺序的限 制。
此外,用户终端可以对分配到第一空口和第二空口上的上行数据进行分流 传输,分流点设备可以接收到在相应空口上传输的上行数据。
根据本发明的实施例,方法 500和方法 600中涉及的第一空口可以是 UMTS 空口 ,第二空口可以是 WiFi空口。 当第一空口是 UMTS空口时,第一通信状态 可以是 CELL_DCH态、 CELL_FACH态、 CELL_PCH态、 URA_PCH态和 IDLE 态之一。 当第二空口是 WiFi空口时,第二通信状态可以是连接态、 空闲态、 睡 眠态和关闭态之一。
根据本发明实施例提供的用于数据传输的方法,由于分流点设备基于预定 策略在第一空口和第二空口之间分配了下行数据,用户终端基于预定策略在第 一空口和第二空口之间分配了上行数据,从而分流点设备可以根据在第一空口 上分配的上行数据和下行数据确定第一空口上的通信状态,根据在第二空口上 分配的上行数据和下行数据确定第二空口上的通信状态,因此可以实现第一空 口和第二空口的统一管理,使得有利于改善用户终端的节能,改善网络资源的 使用效率,并缓解对单一空口造成过大的传输负担。
接下来,参考图 7所示的状态机描述当第一空口是 UMTS空口、 第二空口 是 WiFi空口时的状态迁移的例子。 图 7仅仅是个例子,只是为了帮助对本发明 的技术方案进行理解,而并不对本发明的保护范围构成任何限制。 在图 7所示的状态机中 ,每个方框代表支持 UMTS和 WiFi双在线的 UE可以 处于的通信状态,每个方框中上面的通信状态为 UMTS空口上的第一通信状 态,每个方框中下面的通信状态为 WiFi空口上的第二通信状态。
如果在同一第一通信状态或同一第二通信状态中出现了可选状态,则可以 根据状态的迁移门限或其他预定方式来确定具体的状态。 例如,在状态 4中的 第一通信状态中 ,UE可以处于 CELL_DCH态,也可以处于 CELL_FACH态,此 时可以根据 CELL_DCH态和 CELL_FACH态的迁移门限与 UE在 UMTS空口上 的吞吐量之间的关系,来确定 UE处于 CELL_DCH态还是 CELL_FACH态。
分流点设备可以按照如下( 1 )至( 10 )所示的方式对 UMTS空口和 WiFi 空口进行统一管理。 在( 1 )至( 10 )中涉及的某个空口上的数据需求同时考 虑了该空口上的上行数据的吞吐量和下行数据的吞吐量,而上行数据的吞吐量 由 UE进行分配之后确定,下行数据的吞吐量由分流点设备进行分配之后确定。 UE的总数据需求同时包括两个空口上的数据需求,即 UE待发送的总上行数据 和待向 UE发送的总下行数据。
( 1 )处于包括 CELL—DCH态、 CELL—FACH态、 CELL—PCH态、 URA—PCH 态和 IDLE态的任意 UMTS RRC状态的 UE从 UMTS网络覆盖区域 A进入 UMTS 网络与 WLAN网络重复覆盖区域 B ,或者该 UE—直处于 UMTS网络与 WLAN网 络重复覆盖区域 B ,当 UE处于状态 1日寸, UE的 WiFi空口处于关闭状态,如果有 上行数据和 /或下行数据与 UE进行交互,则使用 UMTS空口进行传输。
( 2 )在区域 B内,如果 UE的总数据需求中的一部分数据需求由 WiFi空口 传输能够满足 QoS要求,而另一部分数据需求需要由 UMTS空口传输,则 UE的 通信状态为状态 3。 ( 3 )如果 UE的总数据需求用 WiFi空口传输完全不能满足 QoS要求,即使 与 UMTS空口同时传输也不能满足 QoS要求,则 UE的通信状态为状态 4。
( 4 )如果 UE的总数据需求用 WiFi空口传输完全可以满足吞吐量要求和 QoS要求,则 UE的通信状态为状态 7。
( 5 )如果 UE没有数据需求,即没有数据需要传输,则 UE的通信状态为 状态 9。
( 6 )在区域 B内 ,如果 UE离开 WiFi覆盖区域,则 UE的通信状态为状态 1。
( 7 )在区域 B内 , 当 UE处于状态 3日寸, UE打开 WiFi空口在 WiFi空口上的 通信状态进入连接态,通过 WiFi空口进行部分数据需求的传输, RNC通过向 UE发送信令来使 UE在 UMTS空口上的通信状态迁移到能够承担剩余数据需求 的具有最低功耗状态的 CELL_DCH态或 CELL_FACH态。 如果剩余数据需求在 CELL_DCH态中即可传输完成,则不将 UE迁移到 CELL_FACH态,以避免耗电 量的增加,从而达到节能的目的。
( 8 )在区域 B内 , 当 UE处于状态 4日寸, UE在 WiFi空口上的通信状态进入 关闭状态, RNC通过向 UE发送信令来使 UE在 UMTS空口上的通信状态迁移到 能够承担总数据需求的具有最低功耗状态的 CELL_DCH态或 CELL_FACH态。
( 9 )在区域 B内 , 当 UE处于状态 7日寸, UE在 WiFi空口上的通信状态进入 连接状态, RNC通过向 UE发送信令来使 UE在 UMTS空口上的通信状态迁移到 IDLE态或 CELL_PCH态。如果 UE的 WiFi分流机制(此时 UE在 WiFi空口上的通 信状态进入连接态)需要依赖于 UMTS的 RRC连接,即与 WiFi分流机制相关的 信令需要通过 RRC连接传输,则 RNC会将 UE在 UMTS空口上的通信状态迁移 到 CELL_PCH态,否则 RNC将 UE在 UMTS空口上的通信状态迁移到 IDLE态。 ( 10 )在区域 B内 ,当 UE处于状态 9日寸, UE在 WiFi空口上的通信状态进入 空闲态或关闭态, RNC通过向 UE发送信令来使 UE在 UMTS空口上的通信状态 迁移到 IDLE态或 CELL_PCH态。 如果 UE的 WiFi分流机制需要依赖于 UMTS的 RRC连接,即与 WiFi分流机制相关的信令需要通过 RRC连接传输,则 RNC会将 UE在 UMTS空口上的通信状态迁移到 CELL_PCH态,由 UMTS空口负责监听寻 呼消息,还可以监听与 WiFi分流机制相关的信令,这样可以避免后续数据传输 可能造成的信令风暴,此时 UE在 WiFi空口上的通信状态进入关闭态。 如果 UE 的 WiFi分流机制不依赖于 UMTS的 RRC连接,即与 WiFi分流机制相关的信令需 要通过 WiFi空口传输,则 RNC将 UE在 UMTS空口上的通信状态迁移到 IDLE态, 此时 UE在 WiFi空口上的通信状态进入空闲态,由 WiFi空口负责监听寻呼消息, 还可以监听与 WiFi分流机制相关的信令,这样同样可以避免后续数据传输可能 造成的信令风暴。
此外,在图 7所示的状态机中 ,UE在 WiFi空口上的关闭态也可以被替换为 睡眠态, UE在 UMTS空口上的 CELL_PCH态也可以被替换为 URA_PCH态,这 样可以进一步节省用于支持更强移动性的信令开销。
另外,在 WiFi分流场景中 ,可以以 UE的业务类型来进行数据分流,将与 QoS要求低的业务类型对应的数据分流到 WiFi空口上传输,将与 QoS要求高的 业务类型对应的数据分流到 UMTS空口上传输。 下面,结合图 8描述根据业务 类型对 UMTS空口和 WiFi空口进行统一管理而进行分流传输的两个例子。
第一例子:
最初 , UE在只有 UMTS网络覆盖的区域 A中正在使用 VoIP业务, UE在 UMTS空口上的通信状态为 CELL_FACH态或 CELL_DCH态, WiFi空口上的通 信状态为关闭(OFF )态。
接着, UE进入 UMTS网络和 WLAN网络的双重覆盖区域 B ,业务类型保持 VoIP , 由于 VoIP业务对延时敏感, QoS要求高, 因此仍将 VoIP分配到 UMTS空 口上, UE在 UMTS空口上的通信状态保持在 CELL_FACH态或 CELL_DCH态, WiFi空口上的通信状态保持在关闭态。
接着, UE的业务类型改变为视频流,该业务类型虽然对延时敏感, QoS 要求高,但是视频流中的非实时部分可以容忍较大的延时, QoS要求低,因此 可以充分利用 WiFi空口传输视频流的非实时部分,此时 UE在 UMTS空口上的 通信状态为 CELL_DCH态,在 WiFi空口上的通信状态为连接( CONNECTED ) 态。
接着, UE的业务类型改变为非实时业务例如网页浏览,这种业务数据需 求量大,但是可以容忍较大的延时, QoS要求低, WiFi空口完全可以满足,此 时 UE在 UMTS空口上的通信状态为 CELL_PCH态或 IDLE态(如果与 WiFi分流 机制相关的信令需要通过 UMTS的 RRC连接传输,则 UMTS空口上的通信状态 为 CELL_PCH态), UE在 WiFi空口上的通信状态为连接态。
接着, UE无数据传输需求, UE在 UMTS空口上的通信状态进入 IDLE态, 在 WiFi空口上的通信状态进入空闲( IDLE )态。 由于在 WiFi空口的空闲态中 可以监听寻呼消息, 因此在该情况下, 由 WiFi空口负责监听寻呼消息。
接着, UE的业务类型为 keep-alive消息, UE在 UMTS空口上的通信状态为 CELL_PCH态或 IDLE态(如果与 WiFi分流机制相关的信令需要通过 UMTS的 RRC连接传输,则 UMTS空口上的通信状态为 CELL_PCH态), WiFi空口上的 通信状态进入连接态, 由 WiFi空口负责发送 /接收这种间歇性的小数据包。 接着, UE的业务类型再次变为非实时业务如网页浏览, UE在 UMTS空口 上的通信状态为 CELL_PCH态或 IDLE态(如果与 WiFi分流机制相关的信令需 要通过 UMTS的 RRC连接传输,则 UMTS空口上的通信状态为 CELL_PCH态), WiFi空口上的通信状态为连接态。
最后, UE离开区域 B再次进入区域 A , UMTS空口上的通信状态进入与现 有技术相同的单制式控制的阶段,例如对于视频流业务,UE在 UMTS空口上的 通信状态为 CELL_DCH态, UE在 WiFi空口上的通信状态变为关闭态。
第二例子:
第二例子与第一例子的区别在于 UE无数据传输需求的情况下的通信状态 以及发送 /接收 keep-alive消息的情况下的通信状态。
在 UE没有数据传输需求的阶段 , UE在 UMTS空口上的通信状态为 CELL_PCH态,负责监听 PICH消息以便接收寻呼消息, UE在 WiFi空口上的通 信状态为关闭态。
在 keep-alive消息发送 /接收的阶段, UE在 UMTS空口上的通信状态为 CELL_PCH态,并随时与 CELL_FACH态进行切换,以进行 keep-alive消息的发 送 /接收, UE在 WiFi空口上的通信状态为关闭态。
接下来,结合 9描述根据本发明实施例的用于数据传输的方法 900。
S910:基于预定策略将待向用户终端发送的下行数据分配到第一空口和第 二空口上,其中用户终端通过第一空口经由第一接入网连接到核心网 ,并通过 第二空口经由第二接入网连接到核心网。
S920:通过第一空口向用户终端发送分配到第一空口上的下行数据,以使 用户终端基于该下行数据的吞吐量和分配到第一空口上的上行数据的吞吐量, 确定用户终端在第一空口上所处的第一通信状态,并进入第一通信状态。 分流点设备向 UE发送分配到第一空口上的下行数据。 由于 UE在第一空口 上所处的第一通信状态可以由 UE自己控制,例如在 LTE网络中 , 因此 UE根据 分流点设备发送的下行数据的吞吐量,再结合 UE分配到第一空口上的上行数 据的吞吐量,可以自己确定在第一空口上的第一通信状态,并进入该通信状态 中。
例如,在 LTE系统中 , UE接收的下行数据的吞吐量对于 UE确定通信状态 而言只有两种取值,即吞吐量为 0以及吞吐量大于 0。 同理, UE发送的上行数 据的吞吐量对于 UE确定通信状态而言,也只有两种取值,即吞吐量为 0以及吞 吐量大于 0。 UE根据自己是否接收到下行数据、 是否需要发送上行数据以及与 状态迁移有关的定时器取值,可以确定自己所处的通信状态。
举例来说,如果处于长 DRX态的 UE连续收到下行数据或者连续有上行数 据需要发送,则 UE进入非 DRX态;如果处于短 DRX态的 UE的定时器期满时没 有上行数据要发送或者没有接收到下行数据,则 UE进入 IDLE态。 在 LTE系统 中 UE确定自己的通信状态的方式与现有技术相同,在此不再赘述。
S930:通过第二空口向用户终端发送分配到第二空口上的下行数据。 S930在 S910之后执行即可,不受图 9所示的执行顺序的限制。
S940:接收用户终端上报的分配到第二空口上待向分流点设备发送的上行 数据的吞吐量,其中第二空口上的上行数据的吞吐量由用户终端基于预定策略 将上行数据分别分配到第一空口和第二空口上之后确定。
UE通过基于预定策略在第一空口和第二空口上分配将发送的上行数据, 可以确定在第二空口上的上行数据的吞吐量。 UE将它所确定第二空口上的上 行数据的吞吐量上报给分流点设备,以使分流点设备可以参考第二空口上的上 行数据的吞吐量来确定第二空口上的通信状态。 当然, UE也可以将第一空口 上的上行数据的吞吐量上报给分流点设备。
通过 UE对上行数据的分配,使得在第一空口和第二空口上发送的上行数 据不再是独立分配得到的,从而有利于第一空口和第二空口的通信状态的统一 管理。
虽然,在方法 1000中 S940在 S910之后执行,但是 S940也可以在 S910之前 执行,还可以与 S910并发执行。
S950:基于第二空口上的下行数据的吞吐量和上行数据的吞吐量,确定用 户终端在第二空口上所处的第二通信状态。
分流点设备基于第二空口上的下行数据的吞吐量和上行数据的吞吐量与 状态的迁移门限的关系,来确定第二通信状态。只要第二空口上的下行数据和 上行数据之一的吞吐量达到迁移门限,分流点设备就可以确定 UE需要进行状 态迁移。
根据本发明的一个实施例,在第二空口上的吞吐量为零的情况下,如果与 数据分流机制相关的信令需要通过第一空口的 RRC连接传输,则确定第二通信 状态为睡眠态或关闭态,并阻止第一通信状态成为 IDLE态。
例如,如果与 WiFi分流机制相关的信令需要通过 LTE的 RRC连接传输,那 么 WiFi空口上如果没有数据传输,则可以将 WiFi空口上的通信状态改变为睡眠 态或关闭态,但是 UE在第一空口上的通信状态不能改变为 IDLE态。 这样,当 UE在第一空口上也没有数据量传输时, UE将进入到长 DRX态,即使用于控制 状态迁移的定时器期满,分流点设备阻止 UE从长 DRX态迁移到 IDLE态,主动 控制 UE维持在长 DRX态,以使 UE可以在长 DRX态中通过 LTE空口接收寻呼消 息以及与 WiFi分流机制相关的信令,从而可以避免后续数据传输可能造成的信 令风暴,并可以降低 UE在没有数据传输时的耗电量。
举例来说,在 LTE系统中 ,当 UE在 LTE空口和 WiFi空口都没有数据传输时, 如果与 WiFi分流机制相关的信令的传输需要经由 LTE的 RRC连接,那么 S-GW 可以确定 WiFi空口上的通信状态为睡眠态或关闭态,而当 eNB准备通知 UE释 放 RRC连接而进入 IDLE态时, eNB首先通知 S-GW准备将 UE迁移到 IDLE态。 由于 S-GW知道与 WiFi分流机制相关的信令传输经由 RRC连接, 因此 S-GW不 允许 eNB通知 UE释放 RRC连接,即不允许 UE进入 IDLE态,此时可以将 UE维持 在长 DRX态。
根据本发明的一个实施例,在第二空口上的吞吐量为零的情况下,如果与 数据分流机制相关的信令不需要通过第一空口的 RRC连接传输,则确定第二通 信状态为空闲态,并不阻止第一通信状态成为 IDLE态。
例如,如果与 WiFi分流机制相关的信令不需要通过 LTE的 RRC连接传输, 即与 WiFi分流机制相关的信令需要通过 WiFi空口传输,那么 WiFi空口上如果没 有数据传输,则可以将 WiFi空口上的通信状态改变为空闲态,通过 WiFi空口监 听寻呼消息以及与 WiFi分流机制相关的信令,此时 UE在 LTE空口上的通信状态 可以改变为 IDLE态。 这样,不仅可以避免后续数据传输可能造成的信令风暴, 还可以降低 UE在没有数据传输时的耗电量。
举例来说,在 LTE系统中 ,当 UE在 LTE空口和 WiFi空口都没有数据传输时, 如果与 WiFi分流机制相关的信令的传输不需要经由 LTE的 RRC连接, 那么 S-GW可以确定 WiFi空口上的通信状态为空闲态,而当 eNB准备通知 UE释放 RRC连接而进入 IDLE态时, eNB首先通知 S-GW准备将 UE迁移到 IDLE态, 由 于 S-GW知道与 WiFi分流机制相关的信令的传输不经由 RRC连接, 因此 S-GW 允许 eNB通知 UE释放 RRC连接,即允许 UE进入 IDLE态。 此时,可以通过 WiFi 空口监听寻呼消息以及与 WiFi分流机制相关的信令,从而可以避免后续数据传 输可能造成的信令风暴,并可以降低 UE在没有数据传输的情况下的耗电量。
S960:向用户终端通知第二通信状态,以使用户终端进入到第二通信状态 中。
虽然在方法 900中 S920在 S950和 S960之前执行,但是 S920也可以在 S950之 后执行,还可以在 S960之后执行,还可以与 S950或 S960并发执行,S920在 S910 之后执行即可。
此外,UE可以对分配到第一空口和第二空口上的上行数据进行分流传输, 而分流点设备可以在相应空口上接收 UE发送的上行数据。
根据本发明的实施例,方法 900涉及的第一空口可以是 LTE空口 ,第二空 口可以是 WiFi空口。 当第一空口是 LTE空口时 , 第一通信状态可以是 CONNECTED态、 短 DRX态、 长 DRX态和 IDLE态之一。 第二通信状态可以是 连接态、 空闲态、 睡眠态和关闭态之一。
根据本发明实施例提供的用于数据传输的方法,由于分流点设备基于预定 策略在第一空口和第二空口之间分配了下行数据,用户终端基于预定策略在第 一空口和第二空口之间分配了上行数据,从而分流点设备根据在第二空口上分 配的上行数据和下行数据确定第二空口上的通信状态,并且分流点设备通过向 用户终端发送分配到第一空口上的下行数据,可以使用户终端确定第一空口上 的通信状态。 因此,由于数据在第一空口和第二空口上的分配关系,可以实现 第一空口和第二空口的统一管理,使得有利于改善用户终端的节能,改善网络 资源的使用效率,并缓解对单一空口造成过大的传输负担。
在 LTE网络与 WLAN网络具有紧耦合形式的情况下,与通信状态有关的状 态机具有与图 7所示的状态机相似的状态形式。与图 7所示的状态机不同之处在 于,第一空口是 LTE空口而不是 UMTS空口 ,因此图 7所示的方框中上面的通信 状态为 LTE空口上的第一通信状态,包括非 DRX态、 短 DRX态、 长 DRX态和 IDLE态。
LTE网络与 WLAN网络紧耦合形式对应的状态机的描述可以参考对图 7所 示的状态机的具体描述,将 CELL_DCH态替换为非 DRX态、 将 CELL_FACH态 替换为短 DRX态、 将 CELL_PCH态、 URA_PCH态替换为长 DRX态、 将 UMTS 空口的 IDLE态替换为 LTE空口的 IDLE态即可。
在 LTE网络与 WLAN网络紧耦合形式的情况下,如果出现如图 8所示的业 务场景,则 UE的通信状态也可以表现出与第一例子和第二例子相似的状态迁 移。 不同之处在于,将 UMTS空口上的 CELL_DCH态替换为 LTE空口上的非 DRX态 /短 DRX态,将 UMTS空口上的 CELL_PCH态/ IDLE态替换为 LTE空口上 的长 DRX态/ IDLE态,将 UMTS空口上的 CELL_PCH态与 CELL_FACH态切换替 换为 LTE空口上的长 DRX态与短 DRX态切换。
无论是图 7、 图 8所示的例子,还是与图 7、 图 8类似的与 LTE空口和 WiFi 空口有关的例子,都只是为了帮助理解本方明而进行的示例性说明,并不对本 发明的保护范围构成限制。
接下来,结合图 10描述根据本发明实施例的用于数据传输的方法 1000。 如图 1000所示,方法 1000包括: S1010:基于预定策略将待向分流点设备发送的上行数据分配到第一空口 和第二空口上,其中用户终端通过第一空口经由第一接入网连接到核心网,并 通过第二空口经由第二接入网连接到核心网;
S1020:通过第一空口向分流点设备发送分配到第一空口上的上行数据。 S1030:通过第二空口向分流点设备发送分配到第二空口上的上行数据。 例如,方法 1000可以由用户终端执行。 分流点设备可以是 RNC、 SGSN、 GGSN等。 用户终端基于预定策略在第一空口和第二空口之间分配上行数据, 使得可以对在第一空口和第二空口上传输的上行数据进行灵活地分配,从而有 利于将第一空口和第二空口上的通信状态联系起来,避免对第一空口和第二空 口独立地进行管理。 因此,通过利用根据本发明实施例的方法,有利于实现对 第一空口和第二空口的统一管理,从而有利于改善用户终端的节能,改善网络 资源的使用效率,并缓解对单一空口造成过大的传输负担。
在 S1010中 ,可以通过多种方式在第一空口和第二空口之间分配待向分流 点设备发送的上行数据。通过分配上行数据,使得在第一空口和第二空口上发 送的上行数据不再是独立分配得到的,因此有利于第一空口和第二空口的通信 状态的统一管理。 下面,详细描述分配上行数据的不同方式。
根据本发明的一个实施例,基于待向分流点设备发送的上行数据的服务质 量要求,将服务质量要求超过预定服务质量要求的上行数据分配到第一空口 上,将服务质量要求未超过预定服务质量要求的的上行数据分配到第二空口 上。
上行数据的服务质量( Quality of Service , QoS )要求可以包括延时、 时延 抖动、 传输带宽等。 无论是在 UMTS网络中还是在 LTE网络中 ,UE可以通过查 询 PDP context来得到 QoS要求。
例如,在预定服务质量要求是 0.1秒延时的情况下,可以认为延时要求低 于 0.1秒的上行数据具有高服务质量要求,延时要求等于或高于 0.1秒的上行数 据具有低服务质量要求,从而可以将具有高服务质量要求的上行数据分配到第 一空口上,将具有高服务质量要求的上行数据分配到第二空口上。
可以基于待向分流点设备发送的上行数据所属的业务类型,确定服务质量 要求。举例来说,当上行数据是文本上传业务时,由于文本上传业务要求尽力 而为交付即可,因此可以确定该上行数据的服务质量要求低。当上行数据是在 线语音业务时,由于在线语音业务对实时性要求高,因此可以确定该上行数据 的服务质量高。
根据本发明的一个实施例,在通过第二空口传输待向分流点设备发送的上 行数据满足上行数据的服务质量要求的情况下,如果通过第二空口传输上行数 据满足上行数据的吞吐量要求,则将上行数据全部分配到第二空口上。
如果在第二空口上传输上行数据同时满足上行数据的服务质量要求和上 行数据的吞吐量要求,则将上行数据都分配到第二空口上。
吞吐量要求可以是指在单位时间内要求传输的数据量大小。数据量大小可 以通过测量缓存器中缓存的数据来得到。
根据本发明的一个实施例,在通过第二空口传输待向分流点设备发送的上 行数据的一部分满足该一部分上行数据的服务质量要求和吞吐量要求、而传输 上行数据的另一部分不满足该另一部分上行数据的服务质量要求或吞吐量要 求的情况下,将该一部分上行数据分配到第二空口上,将该另一部分上行数据 分配到第一空口上。 如果上行数据中有一部分适合在第二空口上传输,即第二空口可以同时满 足该部分下行数据的服务质量要求和吞吐量要求,则将这部分下行数据分配到 第二空口上。对于剩下的那部分上行数据而言,第二空口可能不能满足其服务 质量要求,也可能不能满足其吞吐量要求,还可能既不满足其服务质量要求、 又不满足其吞吐量要求,此时,将剩下的这部分上行数据分配到第一空口上。
根据本发明的一个实施例,在通过第二空口传输待向分流点设备发送的上 行数据不满足上行数据的服务质量要求的情况下,将上行数据全部分配到第一 空口上。
如果第二空口不满足上行数据的服务质量要求,则无论第一空口是否满足 上行数据的服务质量要求,都将上行数据全部分配到第一空口上。
根据本发明的一个实施例,在不需要向分流点设备发送上行数据的情况 下,不将上行数据分配到第一空口和第二空口上。
由于没有向分流点设备发送的上行数据,因此在第一空口和第二空口上不 分配上行数据。
根据本发明的一个实施例,在需要与分流点设备执行心跳机制过程的情况 下,将保活消息分配到负责监听寻呼消息的第一空口或第二空口上。
网络侧与 UE通过相互发送 keep-alive消息来执行心跳机制,此时 UE待向分 流点设备发送的上行数据只有 keep-alive消息。 分流点设备可以将 keep-alive消 息分配到负责监听寻呼消息的第一空口或第二空口进行发送,而在另一空口上 则不分配任何上行数据。
根据本发明的一个实施例,在不能通过第二空口接入第二接入网的情况 下,始终将待向分流点设备发送的上行数据分配到第一空口上。 例如,当 UE的第二空口关闭时,或者当 UE的第二空口对应的信道质量迅 速下降时, UE不能再使用第二空口接入第二接入网。 对于网络侧而言, UE的 第二空口不可用。 此时, UE可以将上行数据全部分配到第一空口上。 第一空 口可以是 UE始终保持在线的空口。
虽然上面描述了多种将上行数据在第一空口和第二空口之间进行分配的 方式,但是本领域技术人员还可以想到其他分配上行数据的方式。通过基于预 定策略分配上行数据,可以将第一空口和第二空口统一起来进行管理。
在 S1020和 S1030中 ,UE在第一空口和第二空口之间分配了上行数据之后, 将分配到第一空口上的上行数据通过第一空口向分流点设备发送,将分配到第 二空口上的上行数据通过第二空口向分流点设备发送,从而可以实现上行数据 的分流传输。该分流传输不是像现有技术那样独立地进行的,而是通过统一管 理分配之后进行的。 由于统一管理的存在,有可能改善网络传输效率,降低网 络传输负担,优化用户通信体验,并降低通信终端耗电量。
虽然在方法 1000中 S1030在 S1020之前执行,但是 S1030也可以在 S1020之 后执行,还可以与 S1020并发执行。
根据本发明实施例提供的用于数据传输的方法,用户终端通过基于预定策 略在第一空口和第二空口之间分配上行数据,可以对在第一空口和第二空口上 传输的上行数据进行灵活地分配,从而有利于将第一空口和第二空口上的通信 状态联系起来,避免对第一空口和第二空口独立地进行管理,因此,有利于实 现对第一空口和第二空口的统一管理,从而有利于改善用户终端的节能,改善 网络资源的使用效率,并缓解对单一空口造成过大的传输负担。
下面,参考图 11描述根据本发明实施例的用于数据传输的方法 1100。 S1110:基于预定策略将待向分流点设备发送的上行数据分配到第一空口 和第二空口上,其中用户终端通过第一空口经由第一接入网连接到核心网,并 通过第二空口经由第二接入网连接到核心网。
S1140: 向分流点设备上报分别分配到第一空口和第二空口上的上行数据 的吞吐量。
UE在 S1110中在第一空口和第二空口上分配了上行数据之后, UE通过分 别测量缓存在与第一空口相应的缓存器中的数据和与第二空口相应的缓存器 中的数据,可以确定第一空口上的上行数据的吞吐量和第二空口上的上行数据 的吞吐量。
UE将确定的在第一空口上的上行数据的吞吐量和在第二空口上的上行数 据的吞吐量上报给分流点设备。 UE可以直接上报吞吐量,也可以通过上报数 据量来间接上报吞吐量。
S1150:从分流点设备获取用户终端在第一空口上所处的第一通信状态和 在第二空口上所处的第二通信状态,其中第一通信状态由分流点设备基于第一 空口上的下行数据的吞吐量和上行数据的吞吐量而确定,第二通信状态由所述 分流点设备基于第二空口上的下行数据的吞吐量和上行数据的吞吐量而确定, 分别在第一空口和第二空口上的下行数据的吞吐量由分流点设备基于预定策 略将待向用户终端发送的下行数据分配到第一空口和第二空口上之后确定。
UE从分流点设备获取的第一通信状态和第二通信状态可以参考方法 600 中的相应描述,为了避免重复,在此不再赘述。
UE获取的通信状态可以由分流点设备直接向 UE发送信令来通知,也可以 由分流点设备通过其他网络设备向 UE发送信令来通知。 S1160:进入到第一通信状态和第二通信状态中。
UE获取第一通信状态和第二通信状态之后,可以进入相应的通信状态中 进行数据的发送和接收。
UE不仅可以在第一通信状态和第二通信状态中对分配到第一空口和第二 空口上的上行数据进行分流传输,还可以接收分流点设备分配到第一空口和第 二空口上的下行数据的分流传输。
S1120:通过第一空口向分流点设备发送分配到第一空口上的上行数据。
S1130:通过第二空口向分流点设备发送分配到第二空口上的上行数据。
S1120和 S1130只需在 S1110之后执行即可。
根据本发明的实施例,方法 1100中涉及的第一空口可以是 UMTS空口 ,第 二空口可以是 WiFi空口。 当第一空口是 UMTS空口时,第一通信状态可以是 CELL_DCH态、 CELL_FACH态、 CELL_PCH态、 URA_PCH态和 IDLE态之一。 当第二空口是 WiFi空口时,第二通信状态可以是连接态、 空闲态、 睡眠态和关 闭态之一。
根据本发明实施例提供的用于数据传输的方法,由于基于预定策略在第一 空口和第二空口之间分配下行数据和上行数据,从而可以将第一空口和第二空 口上的通信状态联系起来,使得可以实现第一空口和第二空口的统一管理,有 利于改善用户终端的节能,并有利于改善网络资源的使用效率,缓解对单一空 口造成过大的传输负担。
下面,参考图 12描述根据本发明实施例的用于数据传输的方法 1200。
S1210:基于预定策略将待向分流点设备发送的上行数据分配到第一空口 和第二空口上,其中用户终端通过第一空口经由第一接入网连接到核心网,并 通过第二空口经由第二接入网连接到核心网。
S1240: 向分流点设备上报分配到第二空口上的上行数据的吞吐量。
如参考 S1140所述,分流点设备通过测量分配到与第二空口相应的缓存器 中的数据,可以确定第二空口上的上行数据的吞吐量。由于在该实施例中由分 流点设备控制第二空口上的第二通信状态,所以 UE上报第二空口上的上行数 据的吞吐量即可。 当然 UE也可以同时上报第一空口上的上行数据的吞吐量。
S1250:接收分流点设备在第一空口上发送的下行数据,其中第一空口上 发送的下行数据由分流点设备基于预定策略将待向用户终端发送的下行数据 分配到第一空口和第二空口上确定。
分流点设备将下行数据分配之后,可以将分配在第一空口上的下行数据向
UE发送,以辅助 UE进行第一空口上的第一通信状态的判断。 例如,在 LTE系 统中 , UE根据接收的下行数据和发送的上行数据来确定 UE应该迁移到的通信 状态。
S1250只需在 S1260之前执行即可,而不受图 12所示的执行顺序的限制。 S1260:基于在第一空口上接收的下行数据的吞吐量和分配到第一空口上 的上行数据的吞吐量,确定用户终端在第一空口上所处的第一通信状态,并进 入第一通信状态。
UE接收到第一空口上的下行数据之后,可以根据其吞吐量,再结合 UE分 配到第一空口上的上行数据的吞吐量,来确定第一空口上的第一通信状态。例 如, UE根据过去与当前的数据量,通过确定是否接收到下行数据、 是否有上 行数据需要发送,来确定第一通信状态。如果没有接收到下行数据且没有接收 到上行数据,则根据定时器的计时,确定第一通信状态。 UE确定第一通信状 态的方式可以参考现有技术,在此不再赘述。
S1260只需在 S1210和 S1250之前执行即可,而不受图 12所示的执行顺序的
S1270:从分流点设备获取用户终端在第二空口上所处的第二通信状态, 并进入第二通信状态,其中第二通信状态由分流点设备基于第二空口上的下行 数据的吞吐量和上行数据的吞吐量而确定。
S1270在 S1240之后执行即可,而不受图 12所示的执行顺序的限制。
分流点设备根据第二空口上的上行数据的吞吐量和下行数据的吞吐量与 状态的迁移门限的关系,可以确定第二空口上的第二通信状态。分流点设备可 以通过向 UE发送信令来通知第二通信状态。 UE收到通知之后,进入到第二通 信状态。
S1220:通过第一空口向分流点设备发送分配到第一空口上的上行数据。
S1230:通过第二空口向分流点设备发送分配到第二空口上的上行数据。
UE不仅可以对分配到第一空口和第二空口上的上行数据进行分流传输, 还可以接收分流点设备分配到第一空口和第二空口上的下行数据的分流传输。
S1220和 S1230在 S1210之后执行即可, 并不受图 12所示的执行顺序的限 制。
根据本发明的实施例,方法 1200中涉及的第一空口可以是 LTE空口 ,第二 空口可以是 WiFi空口。 当第一空口是 LTE空口时 , 第一通信状态可以是 CONNECTED态、 短 DRX态、 长 DRX态和 IDLE态之一。 第二通信状态可以是 连接态、 空闲态、 睡眠态和关闭态之一。
根据本发明实施例提供的用于数据传输的方法,由于分流点设备基于预定 策略在第一空口和第二空口之间分配了下行数据,用户终端基于预定策略在第 一空口和第二空口之间分配了上行数据,从而分流点设备根据在第二空口上分 配的上行数据和下行数据确定第二空口上的通信状态,并且分流点设备通过向 用户终端发送分配到第一空口上的下行数据,可以使用户终端确定第一空口上 的通信状态。 因此,由于数据在第一空口和第二空口上的分配关系,可以实现 第一空口和第二空口的统一管理,使得有利于改善用户终端的节能,改善网络 资源的使用效率,并缓解对单一空口造成过大的传输负担。
下面,结合图 1至图 4的网络架构的具体例子,描述根据本发明实施例的用 于数据传输的方法。
在图 1中 ,分流点设备是 RNC。 RNC基于预定策略将待向 UE发送的下行数 据分配到 UMTS空口和 WiFi空口 ,并确定各空口的下行数据的吞吐量。 UE基 于预定策略将待向 RNC发送的上行数据分配到 UMTS空口和 WiFi空口 ,并向 RNC上报各空口的上行数据的吞吐量。
RNC基于 UMTS空口上的上行数据的吞吐量和下行数据的吞吐量,确定 UE在 UMTS空口上的通信状态,并基于 WiFi空口上的上行数据的吞吐量和下 行数据的吞吐量,确定 UE在 WiFi空口上的通信状态。
接着, RNC向 UE通知 UMTS空口上的通信状态和 WiFi空口上的通信状态, 以使 UE进入相应的通信状态。
此外,RNC基于分配到 UMTS空口和 WiFi空口上的下行数据,将下行数据 从相应空口向 UE分流传输, UE基于分配到 UMTS空口和 WiFi空口上的上行数 据,将上行数据从相应空口向 RNC分流传输。
在图 2中 ,分流点设备是 SGSN。 SGSN基于预定策略将待向 UE发送的下行 数据分配到 UMTS空口和 WiFi空口 ,并确定各空口的下行数据的吞吐量。 UE 基于预定策略将待向 SGSN发送的上行数据分配到 UMTS空口和 WiFi空口 ,并 向 SGSN上报各空口的上行数据的吞吐量。
SGSN基于 UMTS空口上的上行数据的吞吐量和下行数据的吞吐量,确定 UE在 UMTS空口上的通信状态,并基于 WiFi空口上的上行数据的吞吐量和下 行数据的吞吐量,确定 UE在 WiFi空口上的通信状态。
接着, SGSN为了向 UE通知 UE在 UMTS空口上的通信状态, 向 RNC指示 UE在 UMTS空口上的通信状态, RNC向 UE发送信令来使 UE进入到相应的通信 状态。 SGSN向 UE通知 UE在 WiFi空口上的通信状态,以使 UE进入相应的通信 状态。
此外, SGSN基于分配到 UMTS空口和 WiFi空口上的下行数据,将下行数 据从相应空口向 UE分流传输, UE基于分配到 UMTS空口和 WiFi空口上的上行 数据,将上行数据从相应空口向 SGSN分流传输。
在图 3中 ,分流点设备是 GGSN。 GGSN基于预定策略将待向 UE发送的下 行数据分配到 UMTS空口和 WiFi空口 ,并确定各空口的下行数据的吞吐量。 UE 基于预定策略将待向 GGSN发送的上行数据分配到 UMTS空口和 WiFi空口 ,并 向 GGSN上报各空口的上行数据的吞吐量。
GGSN基于 UMTS空口上的上行数据的吞吐量和下行数据的吞吐量,确定 UE在 UMTS空口上的通信状态,并基于 WiFi空口上的上行数据的吞吐量和下 行数据的吞吐量,确定 UE在 WiFi空口上的通信状态。
接着, GGSN为了向 UE通知 UE在 UMTS空口上的通信状态,经由 SGSN向 RNC指示 UE在 UMTS空口上的通信状态,RNC向 UE发送信令来使 UE进入到相 应的通信状态。 GGSN向 UE通知 UE在 WiFi空口上的通信状态,以使 UE进入相 应的通信状态。
此外, GGSN基于分配到 UMTS空口和 WiFi空口上的下行数据,将下行数 据从相应空口向 UE分流传输, UE基于分配到 UMTS空口和 WiFi空口上的上行 数据,将上行数据从相应空口向 GGSN分流传输。
在图 4中 ,分流点设备是 S-GW。 S-GW基于预定策略将待向 UE发送的下行 数据分配到 LTE空口和 WiFi空口。 UE基于预定策略将待向 S-GW发送的上行数 据分配到 LTE空口和 WiFi空口。
UE可以定时向 S-GW上报 WiFi空口上的上行数据的吞吐量,还可以基于 S-GW向 UE进行的吞吐量查询而向 S-GW上报 WiFi空口的上行数据的吞吐量。
S-GW向 UE发送在 LTE空口上分配的下行数据。 在 LTE系统中 ,由于 UE根 据过去与当前的上下行数据量确定在 LTE空口上所处的状态,因此 UE通过接收 S-GW在 LTE空口上发送的下行数据,并结合 UE分配到 LTE空口上的上行数据 , 可以自适应确定 UE在 LTE空口上需要处于的通信状态。
而对于 WiFi空口上的通信状态,则需要 S-GW基于 WiFi空口上的上行数据 的吞吐量和下行数据的吞吐量,来确定 UE在 WiFi空口上的通信状态。 接着, S-GW向 UE发送控制信令来指示 UE进行 WiFi空口上的状态迁移。
此外, S-GW基于分配到 WiFi空口上的下行数据,将该下行数据从 WiFi空 口向 UE分流传输, UE基于分配到 LTE空口和 WiFi空口上的上行数据,将上行 数据从相应空口向 S-GW分流传输。
接下来,结合图 13至 16描述根据本发明实施例的分流点设备的结构框图 , 结合图 17至图 19描述根据本发明实施例的用户终端的结构框图。 图 13是本发明实施例的分流点设备 1300的结构框图。
分流点设备 1300包括分配模块 1310、 第一发送模块 1320、 第二发送模块 1330。分配模块 1310用于基于预定策略将待向用户终端发送的下行数据分配到 第一空口和第二空口上,其中用户终端通过第一空口经由第一接入网连接到核 心网 ,并通过第二空口经由第二接入网连接到核心网。第一发送模块 1320用于 通过第一空口向用户终端发送分配到第一空口上的下行数据。 第二发送模块 1330用于通过第二空口向用户终端发送分配到第二空口上的下行数据。
分配模块 1310、第一发送模块 1320、第二发送模块 1330的上述和其他操作 和 /或功能可以参考上述方法 500中的相应描述,为了避免重复,在此不再赘述。
本发明实施例提供的分流点设备通过基于预定策略在第一空口和第二空 口之间分配下行数据,可以对在第一空口和第二空口上传输的下行数据进行灵 活地分配,从而有利于将第一空口和第二空口上的通信状态联系起来,避免对 第一空口和第二空口独立地进行管理,因此,有利于实现对第一空口和第二空 口的统一管理,从而有利于改善用户终端的节能,改善网络资源的使用效率, 并缓解对单一空口造成过大的传输负担。
图 14是根据本发明实施例的分流点设备 1400的结构框图。
分流点设备 1400的分配模块 1410、第一发送模块 1420、第二发送模块 1430 与分流点设备 1300的分配模块 1310、 第一发送模块 1320、 第二发送模块 1330 基本相同。
根据本发明的实施例,分配模块 1410可以包括如下至少一项:第一分配单 元 1411、 第二分配单元 1412、 第三分配单元 1413、 第四分配单元 1414、 第五分 配单元 1415、 第六分配单元 1416和第七分配单元 1417。 第一分配单元 1411用于基于待向用户终端发送的下行数据的服务质量要 求,将服务质量要求超过预定服务质量要求的下行数据分配到第一空口上,将 服务质量要求未超过预定服务质量要求的下行数据分配到第二空口上。
第二分配单元 1412用于在通过第二空口传输待向用户终端发送的下行数 据满足下行数据的服务质量要求的情况下,如果通过第二空口传输下行数据满 足下行数据的吞吐量要求,则将下行数据全部分配到第二空口上。
第三分配单元 1413用于在通过第二空口传输待向用户终端发送的下行数 据的一部分满足该一部分下行数据的服务质量要求和吞吐量要求、而传输下行 数据的另一部分不满足该另一部分下行数据的服务质量要求或吞吐量要求的 情况下,将该一部分下行数据分配到第二空口上,将该另一部分下行数据分配 到第一空口上。
第四分配单元 1414用于在通过第二空口传输待向用户终端发送的下行数 据不满足下行数据的服务质量要求的情况下,将下行数据全部分配到第一空口 上。
第五分配单元 1415用于在不需要向用户终端发送下行数据的情况下,不将 下行数据分配到第一空口和第二空口上。
第六分配单元 1416用于在需要与用户终端执行心跳机制过程的情况下,将 保活消息分配到负责监听寻呼消息的第一空口或第二空口上。
第七分配单元 1417用于在用户终端不能通过第二空口接入第二接入网的 情况下,始终将待向用户终端发送的下行数据分配到第一空口上。
根据本发明的一个实施例,分流点设备 1400还可以包括服务质量确定模块 1440。服务质量确定模块 1440用于基于待向用户终端发送的下行数据所属的业 务类型,确定服务质量要求。
第一分配单元 1411、 第二分配单元 1412、 第三分配单元 1413、 第四分配单 元 1414、 第五分配单元 1415、 第六分配单元 1416、 第七分配单元 1417和服务质 量确定模块 1440的上述和其他操作和 /或功能可以参考上述方法 500的 S510中 的相应描述,为了避免重复,在此不再赘述。
从第二分配单元 1412、 第三分配单元 1413、 第四分配单元 1414可知,可以 根据服务质量要求和吞吐量要求在第一空口和第二空口之间分配待发送数据, 并且在第二空口可满足传输的情况下,优先将数据分配到第二空口上。如果第 二空口是 WiFi空口 ,那么无论第一空口是 UMTS空口还是 LTE空口 , 由于优先 考虑 WiFi传输,可以为 UMTS网络或 LTE网络提供真正的数据分流,降低 UMTS 空口或 LTE空口对应的网络资源的负担。
