为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本发明实施例中的附图，对本发明实施例中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一部分实施例，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他实施例，都属于本发明保护的范围。 The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is a partial embodiment of the invention, and not all of the embodiments.

为了在多种无线接入技术同时服务一个用户设备时（例如， UMTS和 LTE 两种无线接入技术同时服务一个 UE )进行数据分配，本发明实施例可以在 UE和网络侧各增加一个分发汇聚功能（ Split and Combination Function, SCF ) 实体。以***包含 UMTS和 LTE两种无线接入技术为例，数据发送方的 SCF 实体负责将数据从 UMTS和 LTE两种无线接入技术的链路上分发出去，数据接收方的 SCF实体负责将数据从 UMTS和 LTE两种无线接入技术的链路上汇聚起来。增加 SCF实体后对应的协议栈结构示意图可以参见图 1或图 2。 In order to perform data distribution when a plurality of radio access technologies simultaneously serve one user equipment (for example, UMTS and LTE two radio access technologies simultaneously serve one UE), the embodiment of the present invention may add one distribution aggregation to each of the UE and the network side.

For a schematic diagram of the corresponding protocol stack structure after adding an SCF entity, refer to FIG. 1 or FIG. 2.

图 3为本发明多种无线接入技术同时服务一个用户设备的数据分配方法一实施例的方法流程示意图，包括： FIG. 3 is a schematic flowchart of a method for a data distribution method for simultaneously serving a user equipment by using multiple radio access technologies according to an embodiment of the present invention, including:

步骤 31: 获取每种无线接入技术的链路的带宽信息，以及每种无线接入技术的链路上已经发送的数据量； Step 31: Obtain bandwidth information of links of each radio access technology, and the amount of data that has been sent on the link of each radio access technology;

步骤 32: 根据获取的所述每种无线接入技术的链路的带宽信息，以及每种无线接入技术的链路上已经发送的数据量，确定待采用的无线接入技术的链路； Step 32: Determine, according to the obtained bandwidth information of the link of each radio access technology, and the amount of data that has been sent on the link of each radio access technology, determine a link of the radio access technology to be adopted;

步骤 33: 在确定的所述待采用的无线接入技术的链路上，向所述用户设备发送待发送的数据。 Step 33: Send the data to be sent to the user equipment on the determined link of the radio access technology to be used.

本实施例在多种无线接入技术同时服务一个用户设备时，通过根据每种无线接入技术的链路的带宽信息，以及每种无线接入技术的链路上已经发送的数据量，确定待采用的无线接入技术的链路，可以选择合适的无线接入技术的链路以发送待发送的数据，实现待传输给该用户设备的数据在多种无线接入技术链路间的合理分配，并且可以充分利用带宽资源及提高***性能。 In this embodiment, when multiple radio access technologies simultaneously serve one user equipment, the bandwidth information of the link according to each radio access technology and the amount of data that has been sent on the link of each radio access technology are determined. The link of the radio access technology to be used may select a link of a suitable radio access technology to transmit data to be transmitted, and realize that the data to be transmitted to the user equipment is reasonable among multiple radio access technology links. Allocate, and can make full use of bandwidth resources and improve system performance.

在另一实施例中，假设无线接入技术包括第一无线接入技术和第二无线接入技术，则所述获取每种无线接入技术的链路的带宽信息可以包括：第一无线接入技术的接入网节点接收第二无线接入技术的接入网节点主动上报的所述第二无线接入技术的链路的带宽信息；或者，第一无线接入技术的接入网节点向第二无线接入技术的接入网节点发送请求，并接收所述第二无线接入技术的接入网节点根据所述请求返回的所述第二无线接入技术的链路的带宽信息。 In another embodiment, assuming that the radio access technology includes the first radio access technology and the second radio access technology, the acquiring the bandwidth information of the link of each radio access technology may include: The access network node of the incoming technology receives the bandwidth information of the link of the second radio access technology that is actively reported by the access network node of the second radio access technology; or the access network node of the first radio access technology Sending a request to the access network node of the second radio access technology, and receiving the bandwidth information of the link of the second radio access technology returned by the access network node of the second radio access technology according to the request .

其中，例如，该第二无线接入技术的接入网节点可以通过容量分配消息主动上报第二无线接入技术的链路的带宽信息；或者，该请求可以为容量分配请求消息，该响应消息可以为携带第二无线接入技术的链路的带宽信息的容量分配响应消息。 For example, the access network node of the second radio access technology may actively report the bandwidth information of the link of the second radio access technology by using the capacity allocation message; or the request may be a capacity allocation request message, and the response message Can be bandwidth information of a link carrying the second radio access technology Capacity allocation response message.

例如，该带宽信息可以具体包括：容量分配值和所述容量分配值对应的分配间隔（interval ) , 即，该容量分配值为该分配间隔内可以分配的最大数据量。 For example, the bandwidth information may specifically include: a capacity allocation value and an allocation interval corresponding to the capacity allocation value, that is, the capacity allocation value is a maximum amount of data that can be allocated in the allocation interval.

通过上述流程第一无线接入技术的接入网节点可以获取第二无线接入技术的链路的带宽信息，由于第一无线接入技术的接入网节点会获知自身的无线接入技术的链路的带宽信息，即也可以获取第一无线接入技术的链路的带宽信息，从而实现获取每种无线接入技术的带宽信息。 The access network node of the first radio access technology can obtain the bandwidth information of the link of the second radio access technology, and the access network node of the first radio access technology learns its own radio access technology. The bandwidth information of the link, that is, the bandwidth information of the link of the first radio access technology, can also obtain the bandwidth information of each radio access technology.

另外，在无线接入技术包括第一无线接入技术和第二无线接入技术的基础上，所述获取每种无线接入技术的链路上已经发送的数据量可以包括：第一无线接入技术的接入网节点可以根据其记录并更新的第一无线接入技术的链路已经发送的数据量信息和第二无线接入技术的链路已经发送的数据量信息，获取第一无线接入技术的链路上已经发送的数据量和第二无线接入技术的链路上已经发送的数据量。 In addition, on the basis that the radio access technology includes the first radio access technology and the second radio access technology, the amount of data that has been sent on the link for acquiring each radio access technology may include: The access network node of the ingress technology can obtain the first wireless according to the data volume information that has been sent by the link of the first radio access technology that is recorded and updated, and the data volume information that has been sent by the link of the second radio access technology. The amount of data that has been transmitted on the link of the access technology and the amount of data that has been sent on the link of the second radio access technology.

所述根据所述每种无线接入技术的链路的带宽信息，以及每种无线接入技术的链路上已经发送的数据量，确定待采用的无线接入技术的链路可以包括： Determining, according to the bandwidth information of the link of each radio access technology, and the amount of data that has been sent on the link of each radio access technology, determining the link of the radio access technology to be adopted may include:

如果第一无线接入技术的链路与第二无线接入技术的链路的带宽之比，大于或等于第一无线接入技术的链路与第二无线接入技术的链路的已经发送的数据量之比，则所述待采用的无线接入技术的链路为第一无线接入技术的链路； If the ratio of the bandwidth of the link of the first radio access technology to the link of the second radio access technology is greater than or equal to the link of the first radio access technology and the link of the second radio access technology has been sent The ratio of the amount of data, the link of the radio access technology to be adopted is the link of the first radio access technology;

如果第一无线接入技术的链路与第二无线接入技术的链路的带宽之比，小于第一无线接入技术的链路与第二无线接入技术的链路的已经发送的数据量之比，则所述待采用的无线接入技术的链路为第二无线接入技术的链路。 If the ratio of the bandwidth of the link of the first radio access technology to the link of the second radio access technology is smaller than the already transmitted data of the link of the first radio access technology and the link of the second radio access technology The ratio of the quantity, the link of the radio access technology to be adopted is the link of the second radio access technology.

当然，如果上述的无线接入技术包括至少三种的无线接入技术，则确定方法也是类似的，例如，确定待采用的无线接入技术的链路具体可以为：确定已经发送的数据量与带宽信息之比最小的无线接入技术的链路为待采用的无线接入技术的链路。 Certainly, if the foregoing radio access technology includes at least three types of radio access technologies, the determining method is similar. For example, determining the link of the radio access technology to be used may be: The link of the radio access technology with the smallest ratio of the amount of data that has been transmitted to the bandwidth information is the link of the radio access technology to be adopted.

另外，上述的第一无线接入技术的接入网节点可以称为锚点，该锚点可以是指将数据分发到多种无线接入技术的链路上传输的分发节点。例如，该锚点具体的分发功能可以由第一无线接入技术的接入网节点中的 SCF实体来执行。 In addition, the access network node of the first radio access technology may be referred to as an anchor point, and the anchor point may refer to a distribution node that transmits data to a link of multiple radio access technologies. For example, the anchor-specific distribution function can be performed by an SCF entity in the access network node of the first radio access technology.

本发明实施例将以多种无线技术包括 UMTS接入技术和 LTE接入技术两种无线接入技术为例，且以 UMTS接入网中的无线网络控制器（ Radio Network Controller, RNC )作为锚点进行数据分发为例，则上述第一无线接入技术的接入网节点为 RNC ,第二无线接入技术的接入网节点为 LTE接入网中的演进基站（eNodeB ) 。当然，如果由 eNodeB作为锚点进行数据分发时，则上述第一无线接入技术的接入网节点为 eNodeB,第二无线接入技术的接入网节点为 RNC。本领域技术人员可以明了，采用其它无线接入技术的组合，例如，采用 UMTS接入技术和 GSM接入技术服务同一个用户设备、或者，采用 GSM 接入技术和 LTE接入技术服务同一个用户设备，也可以适用上述数据分配方法，此处不再赘述。此外，本领域的技术人员能够明了，采用至少三种的无线接入技术服务同一个用户设备时的数据分配方法，与上述采用两种无线接入技术服务同一个用户设备的数据分配方法类似，此处也不再赘述。 In the embodiment of the present invention, two radio access technologies, including a UMTS access technology and an LTE access technology, are taken as an example, and a radio network controller (RNC) in the UMTS access network is used as an anchor. For example, the access network node of the first radio access technology is the RNC, and the access network node of the second radio access technology is the evolved base station (eNodeB) in the LTE access network. Of course, if the data is distributed by the eNodeB as an anchor point, the access network node of the first radio access technology is an eNodeB, and the access network node of the second radio access technology is an RNC. A person skilled in the art can understand that a combination of other radio access technologies is used, for example, the UMTS access technology and the GSM access technology are used to serve the same user equipment, or the GSM access technology and the LTE access technology are used to serve the same user. For the device, the above data distribution method can also be applied, and details are not described herein again. In addition, those skilled in the art can understand that the data allocation method when using at least three radio access technologies to serve the same user equipment is similar to the data distribution method in which the two radio access technologies are used to serve the same user equipment. It will not be repeated here.

图 4为本发明实施例中 RNC向 eNodeB请求 LTE链路的带宽信息的示意图， RNC作为锚点，通过容量分配请求消息向 eNodeB请求 LTE链路的带宽信息包括： 4 is a schematic diagram of an RNC requesting an eNodeB for bandwidth information of an LTE link according to an embodiment of the present invention. The RNC is used as an anchor point, and requesting, by the capacity allocation request message, the bandwidth information of the LTE link to the eNodeB includes:

步骤 41: RNC向 eNodeB发送容量分配请求（ capacity request )消息，让 eNodeB上报 LTE链路的带宽信息。 Step 41: The RNC sends a capacity allocation request message to the eNodeB, so that the eNodeB reports the bandwidth information of the LTE link.

步骤 42: eNodeB向 RNC返回容量分配响应（ capacity allocation )消息。其中，该容量分配响应消息携带该 LTE链路的带宽信息，该带宽信息，例如，可以包括： LTE链路的容量分配值和分配间隔（interval ) 。上述 eNodeB向 RNC返回的容量分配响应消息中包括 LTE链路的容量分配值，其计算公式为： LTE链路的容量分配值 =Min(eNodeB分配的容量值、 eNodeB与 RNC之间的 Sl，接口限制的容量值)。所述 eNodeB分配的容量值为在 interval内 eNodeB能够传输的最大数据量，所述 Sl，接口限制的容量值为在 interval内 S1'口能够传输的最大数据量。 Step 42: The eNodeB returns a capacity allocation message to the RNC. The capacity allocation response message carries the bandwidth information of the LTE link, and the bandwidth information, for example, may include: a capacity allocation value and an allocation interval of the LTE link. The capacity allocation response message returned by the eNodeB to the RNC includes a capacity allocation value of the LTE link, and the calculation formula is: the capacity allocation value of the LTE link=Min (the capacity value allocated by the eNodeB, the S1 between the eNodeB and the RNC, the interface) Limited capacity value). The capacity value allocated by the eNodeB is the maximum amount of data that the eNodeB can transmit in the interval. The capacity limit of the interface is the maximum amount of data that can be transmitted by the S1' port in the interval.

当然，也可以直接将容量分配值与分配间隔的商作为带宽信息携带在上述的容量分配响应消息中。本领域的技术人员能够明了，上述带宽信息仅是例举，本发明实施例并不对带宽信息的具体形式进行限定。 Of course, the quotient of the capacity allocation value and the allocation interval may be directly carried as bandwidth information in the capacity allocation response message described above. It is to be understood by those skilled in the art that the above-mentioned bandwidth information is only an example, and the specific embodiment of the bandwidth information is not limited in the embodiment of the present invention.

相应的， RNC可以获知自身所在的 UMTS链路的带宽信息，类似的，该 UMTS 链路的带宽信息可以包括 UMTS 链路的容量分配值和分配间隔 ( interval ) , 该 UMTS链路的容量分配值的计算公式可以为： UMTS链路的容量分配值 = Min ( NodeB分配的容量值、 Iub接口限制的容量值）。所述 NodeB分配的容量值为在 interval内 RNC控制的 NodeB能够传输的最大数据量，所述 Iub接口限制的容量值为在 interval内 RNC对应的 Iub接口能够传输的最大数据量。 Correspondingly, the RNC can obtain the bandwidth information of the UMTS link where the UMTS link is located. Similarly, the bandwidth information of the UMTS link can include a capacity allocation value and an allocation interval of the UMTS link, and a capacity allocation value of the UMTS link. The calculation formula can be: Capacity allocation value of UMTS link = Min (capacity value assigned by NodeB, capacity value limited by Iub interface). The capacity value assigned by the NodeB is the maximum amount of data that can be transmitted by the NodeB controlled by the RNC in the interval, and the capacity value limited by the Iub interface is the maximum amount of data that can be transmitted by the Iub interface corresponding to the RNC in the interval.

另外， RNC作为锚点可以记录更新已发送的数据量信息，因此，根据记录并更新的数据量信息， RNC可以获取每种无线接入技术的链路上已经发送的数据量，具体来讲， RNC可以获取 UMTS 的链路上已经发送的数据量和 LTE的链路上已经发送的数据量。 In addition, the RNC can record and update the sent data amount information as an anchor point. Therefore, according to the data amount information recorded and updated, the RNC can acquire the amount of data that has been sent on the link of each radio access technology, specifically, The RNC can obtain the amount of data that has been sent on the UMTS link and the amount of data that has been sent on the LTE link.

至此，获取了 UMTS和 LTE两种无线接入技术的链路的带宽信息和已经发送的数据量，之后可以确定待采用的无线接入技术的链路。 So far, the bandwidth information of the link of the two UMTS and LTE radio access technologies and the amount of data that has been transmitted are obtained, and then the link of the radio access technology to be adopted can be determined.

具体地，以两种无线接入技术同时服务一个用户设备为例，如果第一无线接入技术的链路与第二无线接入技术的链路的带宽之比，大于或等于第一无线接入技术的链路与第二无线接入技术的链路的已经发送的数据量之比 (或者表述为，第一无线接入技术的链路的带宽与第二无线接入的链路上已经发送的数据量的乘积，大于或等于第二无线接入技术的链路的带宽与第一无线接入的链路上已经发送的数据量的乘积），则所述待采用的无线接入技术的链路为第一无线接入技术的链路；如果第一无线接入技术的链路与第二无线接入技术的链路的带宽之比，小于第一无线接入技术的链路与第二无线接入技术的链路的已经发送的数据流量之比（或者表述为，第一无线接入技术的链路的带宽与第二无线接入的链路上已经发送的数据量的乘积，小于第二无线接入技术的链路的带宽与第一无线接入的链路上已经发送的数据量的乘积），则所述待采用的无线接入技术的链路为第二无线接入技术的链路。 Specifically, the two radio access technologies simultaneously serve one user equipment, if the ratio of the bandwidth of the link of the first radio access technology to the link of the second radio access technology is greater than or equal to the first radio connection. Ratio of the transmitted data to the link of the second radio access technology to the link of the second radio access technology (or the bandwidth of the link of the first radio access technology and the link of the second radio access) The product of the amount of data sent, greater than or equal to the bandwidth of the link of the second radio access technology and the first a product of the amount of data that has been transmitted on the link of the wireless access, and the link of the wireless access technology to be adopted is the link of the first wireless access technology; if the link of the first wireless access technology The ratio of the bandwidth of the link to the second radio access technology is smaller than the ratio of the transmitted data traffic of the link of the first radio access technology to the link of the second radio access technology (or expressed as: The product of the bandwidth of the link of the wireless access technology and the amount of data that has been sent on the link of the second wireless access is smaller than the bandwidth of the link of the second wireless access technology and the link of the first wireless access The product of the radio access technology to be used is the link of the second radio access technology.

举例来说：假设服务于同一个用户设备的 UMTS链路和 LTE链路的带宽比例为 m:n, 那么如果两种无线接入技术的链路上已经发送的数据量比例小于 m:n, 那么待发送的数据包将被分配在 UMTS链路上发送，如果两种无线接入技术的链路已经发送的数据量比例大于 m:n, 那么待发送的数据包将被分配在 LTE链路上发送。也就是说：数据分配的原则是保证不同无线接入技术的链路上发送数据量的比例与不同无线接入技术的链路的带宽比例相等或大致相等，即两者匹配。 For example, if the bandwidth ratio of the UMTS link and the LTE link serving the same user equipment is m:n, then if the proportion of data that has been sent on the links of the two radio access technologies is less than m:n, Then the data packet to be sent will be allocated for transmission on the UMTS link. If the proportion of data transmitted by the links of the two radio access technologies is greater than m:n, the data packet to be transmitted will be allocated on the LTE link. Send on. That is to say: The principle of data distribution is to ensure that the proportion of data transmitted on the links of different radio access technologies is equal to or substantially equal to the bandwidth ratio of links of different radio access technologies, that is, the two match.

以公式可以表示如下：如果（ L容量分配值 *U发包量 *U interval ) > ( U 容量分配值 *L发包量 *L interval ) , 则待发送的数据包被分配在 LTE链路上发送，否则待发送的数据包被分配在 UMTS链路上发送。其中， L容量分配值是指 LTE链路的容量分配值； U发包量是指 UMTS链路上已经发送的数据量； U interval是指 UMTS链路的分配间隔（Interval ) ； U容量分配值是指 UMTS链路的容量分配值， L发包量是指 LTE链路上已经发送的数据量， L interval是指 LTE链路的分配间隔（ Interval ) 。 The formula can be expressed as follows: If (L capacity allocation value *U packet amount *U interval ) > ( U capacity allocation value *L packet amount *L interval ), the data packet to be transmitted is allocated to be transmitted on the LTE link. Otherwise the data packet to be transmitted is allocated for transmission on the UMTS link. The L capacity allocation value refers to the capacity allocation value of the LTE link; the U packet volume refers to the amount of data that has been sent on the UMTS link; the U interval refers to the allocation interval (Interval) of the UMTS link; the U capacity allocation value is Refers to the capacity allocation value of the UMTS link. The L-send packet refers to the amount of data that has been sent on the LTE link, and the L interval refers to the allocation interval (Interval) of the LTE link.

在确定待采用的无线接入技术的链路之后，可以在确定的该待采用的无线接入技术的链路上向用户设备发送数据。 After determining the link of the radio access technology to be employed, data may be transmitted to the user equipment on the determined link of the radio access technology to be employed.

进一步地，本发明可以给出另一实施例，在该另一实施例中，还可以包括：判断所述待发送的数据是否属于已经建立的传输控制协议 Further, the present invention may provide another embodiment. In another embodiment, the method may further include: determining whether the data to be sent belongs to an established transmission control protocol.

( Transport Control Protocol, TCP )流；如果所述待发送的数据属于已经建立的 TCP流，则在传输所述已经建立的 TCP流的无线接入技术的链路上，发送所述待发送的数据；如果所述待发送的数据不属于已经建立的 TCP流，即所述待发送的数据属于新建的 TCP流，则根据获取的所述每种无线接入技术的链路的带宽信息，以及每种无线接入技术的链路上已经发送的数据量，确定待采用的无线接入技术的链路，进而在确定的待采用的无线接入技术的链路上发送待发送的数据。具体可以参见图 5所示实施例。 (Transport Control Protocol, TCP) stream; if the data to be sent belongs to already established The TCP stream, the data to be sent is sent on the link of the radio access technology that transmits the established TCP stream; if the data to be sent does not belong to the established TCP stream, that is, the The data to be sent belongs to the newly created TCP stream, and determines the to-be-used according to the acquired bandwidth information of the link of each radio access technology and the amount of data that has been sent on the link of each radio access technology. The link of the radio access technology, and then the data to be transmitted is sent on the determined link of the radio access technology to be adopted. For details, please refer to the embodiment shown in FIG. 5.

图 5为本发明多种无线接入技术同时服务一个用户设备的数据分配方法另一实施例的方法流程示意图，包括： FIG. 5 is a schematic flowchart of a method for a data distribution method for simultaneously serving a user equipment by using multiple radio access technologies according to another embodiment of the present invention, including:

步骤 51: 判断待发送的数据是否属于已经建立的 TCP流，若否，执行步骤 52, 若是执行步骤 55。 Step 51: Determine whether the data to be sent belongs to the established TCP stream. If no, go to step 52. If yes, go to step 55.

例如，发送端会记录已经建立的 TCP 流的信息，包括已经建立的 TCP 流的五元组（包括：源地址、目的地址、源端口号、目的端口号、协议）以及传输该已经建立的 TCP流的无线技术的链路，例如，发送端可以记录如下信息：已经建立的 TCP流包括 TCP流_1、 TCP流_2, 其对应的五元组分别为五元组_1、五元组 _2 (这些五元组可以形成五元组列表），其传输链路分别为 UMTS链路、 LTE链路（传输不同 TCP流的无线接入技术的链路可以相同也可以不同）。 For example, the sender records the information of the established TCP stream, including the quintuple of the established TCP stream (including: source address, destination address, source port number, destination port number, protocol) and transmits the established TCP. For the link of the wireless technology of the stream, for example, the sender can record the following information: The established TCP stream includes TCP stream_1 and TCP stream_2, and the corresponding five-tuple is quintuple_1 and quintuple. _2 (These five-tuples can form a quintuple list), and their transmission links are UMTS links and LTE links respectively (the links of radio access technologies that transmit different TCP streams can be the same or different).

之后，根据记录的已经建立的 TCP流的五元组列表以及待发送的数据的五元组，则可以判断出待发送的数据是否属于已经建立的 TCP流。 Then, according to the recorded quintuple list of the established TCP stream and the quintuple of the data to be sent, it can be determined whether the data to be sent belongs to the established TCP stream.

步骤 52: 确定该待发送的数据对应的待采用的无线接入技术的链路。具体确定方式可以采用图 3所示实施例的所示的确定方式。例如，以无线接入技术的链路包括第一无线接入技术的链路和第二无线接入技术的链路为例，如果第一无线接入技术的链路与第二无线接入技术的链路的带宽之比，大于或等于第一无线接入技术的链路与第二无线接入技术的链路的已经发送的数据量之比，则确定所述待采用的无线接入技术的链路为第一无线接入技术的链路；如果第一无线接入技术的链路与第二无线接入技术的链路的带宽之比，小于第一无线接入技术的链路与第二无线接入技术的链路的已经发送的数据量之比，则确定所述待采用的无线接入技术的链路为第二无线接入技术的链路。 Step 52: Determine a link of the radio access technology to be adopted corresponding to the data to be sent. The specific determination manner may adopt the determination manner shown in the embodiment shown in FIG. 3. For example, the link of the radio access technology includes the link of the first radio access technology and the link of the second radio access technology, for example, if the link of the first radio access technology and the second radio access technology The ratio of the bandwidth of the link is greater than or equal to the ratio of the amount of data transmitted by the link of the first radio access technology to the link of the second radio access technology, and the radio access technology to be used is determined. The link is the link of the first radio access technology; if the link of the first radio access technology and the link of the second radio access technology a ratio of the ratio of the amount of data sent by the link of the first radio access technology to the link of the second radio access technology, determining that the link of the radio access technology to be used is the second radio The link to the access technology.

在确定待采用的无线接入技术的链路后，可以记录该新建的 TCP流的信息，例如，可以包括：新建的 TCP流的五元组、该新建的 TCP流的传输链路。 After determining the link of the radio access technology to be used, the information of the newly created TCP stream may be recorded, for example, may include: a quintuple of the newly created TCP stream, and a transmission link of the newly created TCP stream.

步骤 53:在确定的待采用的无线接入技术的链路上传输该待发送的数据。步骤 54: 更新各种无线接入技术的链路上已经传输的数据量。 Step 53: Transmit the data to be sent on the determined link of the radio access technology to be adopted. Step 54: Update the amount of data that has been transmitted on the links of the various radio access technologies.

例如，如果确定待采用的无线接入技术的链路为 UMTS链路，则在 UMTS 链路上发送所述待发送的数据后，更新 UMTS链路上已经传输的数据量信息。 For example, if it is determined that the link of the radio access technology to be adopted is a UMTS link, after the data to be transmitted is transmitted on the UMTS link, the amount of data information that has been transmitted on the UMTS link is updated.

步骤 55:在传输该已经建立的 TCP流的无线接入技术的链路上发送所述待发送的数据。 Step 55: Send the data to be transmitted on a link of a radio access technology that transmits the already established TCP stream.

例如，如果待发送的数据属于 TCP流_1 , 且 TCP流_1属于已经建立的流，而该已经建立的 TCP流_1是在 UMTS链路上传输的，则该待发送的数据将被分配在 UMTS链路上继续发送。 For example, if the data to be transmitted belongs to TCP stream_1, and TCP stream_1 belongs to the already established stream, and the established TCP stream_1 is transmitted on the UMTS link, the data to be sent will be The allocation continues to be sent on the UMTS link.

当然，在发送所述待发送的数据后，也可以更新各种无线接入技术的链路上已经传输的数据量信息。 Of course, after the data to be sent is sent, the amount of data that has been transmitted on the links of various radio access technologies can also be updated.

本实施例在多种无线接入技术同时服务一个用户设备时，通过根据每种无线接入技术的链路的带宽信息，以及每种无线接入技术的链路上已经发送的数据量，确定待采用的无线接入技术的链路，选择合适的无线接入技术的链路以发送待发送的数据，实现待传输给该用户设备的数据在多种无线接入技术链路间的合理分配，并且可以充分利用带宽资源及提高***性能。另夕卜，本实施例通过进行 TCP流的判断，保证同一个 TCP流的数据尽量在同一种无线技术的链路上传输，避免 TCP数据包的乱序。 In this embodiment, when multiple radio access technologies simultaneously serve one user equipment, the bandwidth information of the link according to each radio access technology and the amount of data that has been sent on the link of each radio access technology are determined. A link of a radio access technology to be used, selecting a link of a suitable radio access technology to transmit data to be transmitted, and realizing a reasonable allocation of data to be transmitted to the user equipment among multiple radio access technology links And can make full use of bandwidth resources and improve system performance. In addition, in the embodiment, the TCP stream is judged to ensure that the data of the same TCP stream is transmitted on the same wireless technology link as much as possible, thereby avoiding out-of-order of TCP packets.

图 6为本发明多种无线接入技术同时服务一个用户设备的数据分配方法另一实施例的方法流程示意图，本实施例以根据 TCP流进行分发为例，参见图 6, 包括：步骤 61: 确定待发送的数据是否属于已经建立的 TCP流； FIG. 6 is a schematic flowchart of a method for a data distribution method for simultaneously serving a user equipment according to another embodiment of the present invention. The present embodiment is exemplified by a TCP flow distribution. Referring to FIG. 6, the method includes: Step 61: Determine whether the data to be sent belongs to an already established TCP stream.

其中，可以首先确定待发送的数据属于的 TCP流，之后根据记录的信息判断待发送的数据所属的 TCP流是否属于已经建立的 TCP。 The TCP stream to which the data to be sent belongs may be determined first, and then the TCP stream to which the data to be transmitted belongs belongs to the established TCP according to the recorded information.

例如，可以根据五元组确定待发送的数据属于的 TCP流，确定五元组与所述待发送的数据的五元组一致的 TCP 流为所述待发送的数据属于的 TCP 流。例如，待发送的数据的五元组为五元组 _1 , 如果 TCP流_1的五元组也是五元组 _1 , 则待发送的数据属于的 TCP流为 TCP流_1。 For example, the TCP stream to which the data to be transmitted belongs belongs may be determined according to the quintuple, and the TCP stream whose quintual is consistent with the quintuple of the data to be transmitted is determined to be the TCP stream to which the data to be transmitted belongs. For example, the quintuple of the data to be transmitted is a quintuple _1. If the quintuple of the TCP stream_1 is also a quintuple _1, the TCP stream to which the data to be transmitted belongs is the TCP stream_1.

步骤 62: 如果所述待发送的数据属于已经建立的 TCP流，则从所述多种无线接入技术的链路中，确定传输所述待发送的数据所属的已经建立的 TCP 流的无线接入技术的链路为待采用的无线接入技术的链路。 Step 62: If the data to be sent belongs to the established TCP stream, determine, from the links of the multiple radio access technologies, the radio connection of the established TCP stream to which the data to be sent belongs The link into the technology is the link of the radio access technology to be adopted.

当然，如果待发送的数据不属于已经建立的 TCP流，则可以按照图 5的步骤 52-55进行处理。 Of course, if the data to be sent does not belong to the established TCP stream, it can be processed according to steps 52-55 of FIG.

步骤 63: 在所述确定的待采用的无线接入技术的链路上，向所述用户设备发送所述待发送的数据。 Step 63: Send the data to be sent to the user equipment on the determined link of the radio access technology to be used.

例如，发送端会记录各 TCP流的传输链路，例如， TCP流_1在 UMTS 链路上传输，如果待发送的数据属于 TCP 流_1 , 则将待发送的数据在 TCP 流_1上发送。 For example, the sender records the transmission link of each TCP stream. For example, TCP stream_1 is transmitted on the UMTS link. If the data to be sent belongs to TCP stream_1, the data to be sent is on TCP stream_1. send.

本实施例在多种无线接入技术同时服务一个用户设备时，根据 TCP流对应的无线接入技术的链路确定待采用的无线接入技术的链路，选择合适的无线接入技术的链路以发送待发送的数据，实现待传输给该用户设备的数据在多种无线接入技术链路间的合理分配，并且可以充分利用带宽资源及提高系统性能。通过进行 TCP流的判断，保证同一个 TCP流的数据尽量在同一种无线接入技术的链路上传输，避免 TCP数据包的乱序。 In this embodiment, when multiple radio access technologies simultaneously serve one user equipment, the link of the radio access technology to be used is determined according to the link of the radio access technology corresponding to the TCP stream, and the chain of the appropriate radio access technology is selected. The road transmits the data to be sent, and realizes reasonable allocation of data to be transmitted to the user equipment among multiple wireless access technology links, and can fully utilize bandwidth resources and improve system performance. By performing TCP flow judgment, it is ensured that the data of the same TCP stream is transmitted on the link of the same wireless access technology as much as possible, thereby avoiding the disorder of TCP data packets.

在图 6所示的实施例中，如果按照 TCP流进行分发后，还可以根据已经发送的数据量以及带宽进行 TCP流的链路调整。具体如图 7所示。 In the embodiment shown in Fig. 6, if the distribution is performed in accordance with the TCP stream, the link adjustment of the TCP stream can be performed based on the amount of data that has been transmitted and the bandwidth. Specifically as shown in Figure 7.

图 7为本发明多种无线接入技术同时服务一个用户设备的数据分配方法另一实施例的方法流程示意图，包括： FIG. 7 is a data distribution method for simultaneously servicing a user equipment by using multiple radio access technologies according to the present invention; A schematic flowchart of a method of another embodiment includes:

步骤 71：按 TCP流进行数据分发。 Step 71: Data distribution by TCP stream.

具体内容可以参见图 6所示实施例。 For details, please refer to the embodiment shown in FIG. 6.

步骤 72: 判断各种无线接入技术的链路的已经发送的数据量的比例与各种无线接入技术的链路的带宽之比是否匹配，若否，执行步骤 73, 若是执行步骤 74。 Step 72: Determine whether the ratio of the amount of data that has been sent by the links of the various radio access technologies to the bandwidth of the links of the various radio access technologies is matched. If not, go to step 73, and if yes, go to step 74.

其中，带宽之比可以根据每种无线接入技术的链路的带宽信息确定。具体计算过程可以采用图 3所示实施例中所述的内容进行计算。 The bandwidth ratio may be determined according to bandwidth information of a link of each radio access technology. The specific calculation process can be performed using the contents described in the embodiment shown in FIG.

另外，可以设定一个阈值，如果上述各种无线接入技术的链路的已发送数据量的比例与各种无线接入技术的链路的带宽之比的比较值超过该阈值后，则表示不匹配。该比较值可以为两者之比或者两者之差。 In addition, a threshold may be set, if the comparison value of the ratio of the transmitted data amount of the links of the various radio access technologies to the bandwidth of the links of the various radio access technologies exceeds the threshold, Mismatch. The comparison value can be the ratio of the two or the difference between the two.

步骤 73: 对 TCP流进行搬迁处理，将其在另外一种无线接入技术的链路上传输。 Step 73: Relocate the TCP stream and transmit it on the link of another wireless access technology.

例如， ***包括 LTE链路和 UMTS链路， TCP流_1按照步骤 71的处理是在 LTE链路上传输，如果 LTE链路上发送的数据量与 UMTS链路上发送的数据量之比，远远大于 LTE链路的带宽与 UMTS链路的带宽之比，则将 TCP流_1从 LTE链路上传输改为从 UMTS链路上传输。其中， TCP流在某一链路上传输是指属于该 TCP流的数据在该链路上发送，如果某一 TCP流从原来的链路上搬迁到另一链路上传输，则是指将判断出搬迁之前待发送的该 For example, the system includes an LTE link and a UMTS link, and TCP stream_1 is transmitted on the LTE link according to the processing of step 71. If the amount of data transmitted on the LTE link is compared with the amount of data sent on the UMTS link, Far greater than the ratio of the bandwidth of the LTE link to the bandwidth of the UMTS link, the TCP stream_1 is changed from the LTE link transmission to the UMTS link transmission. Wherein, the TCP stream is transmitted on a certain link, and the data belonging to the TCP stream is sent on the link. If a TCP stream is relocated from the original link to another link, it means that Determining which to send before relocation

TCP流的数据在原来的链路上发送，将判断出搬迁后待发送的该 TCP流的数据改为在该另一链路上发送。 The data of the TCP stream is transmitted on the original link, and it is determined that the data of the TCP stream to be transmitted after the relocation is changed to be transmitted on the other link.

步骤 74: 保持 TCP流在原有的无线接入技术的链路上传输。 Step 74: Keep the TCP stream transmitted on the link of the original radio access technology.

本实施例通过调整 TCP流的传输链路，可以平衡各无线接入技术的链路的传输情况，更合理有效地利用网络资源。 In this embodiment, by adjusting the transmission link of the TCP stream, the transmission condition of the links of each radio access technology can be balanced, and the network resources can be utilized more reasonably and effectively.
