技术领域Technical field
本发明涉及无线通信技术领域,尤其涉及一种信息传输方法、装置、系统、相关设备和计算机可读存储介质。The present invention relates to the field of wireless communication technologies, and in particular, to an information transmission method, apparatus, system, related device, and computer readable storage medium.
背景技术Background technique
为了保证数据传输质量,传统的传输控制协议(TCP,Transmission Control Protocol)通过“慢启动”(Slow Start)、“拥塞避免”(Congestion voidance)、“快速重传”(Fast retransmit)、“快速恢复”(Fast Recovery)算法等一系列拥塞控制机制实现对数据传输的拥塞控制。以TCP-Reno为例,慢启动主要是根据网络情况调整拥塞窗口(CWnd,Congestion Window)逐步增加每次发送的数据量,以避免一开始就大量发送数据包而发生拥塞现象,CWnd呈现指数形式向上递增;拥塞避免的基本思想是在慢启动中CWnd达到预设的慢启动阈值时,调整CWnd以线性形式增加,避免增长过快导致网络拥塞;快速重传是接收方每收到一个失序的报文段后就立即发出重复确认,发送方只要连续收到三个重复确认就应当立即重传对方尚未收到的报文段,而不必继续等待重传计时器到期;快速恢复是指当发送方连续收到三个重复确认时,把慢启动阈值减半,以防止网络发生拥塞。 In order to ensure the quality of data transmission, the traditional Transmission Control Protocol (TCP) passes the "Slow Start", "Congestion Void" (Congestion Void), "Fast retransmit", "Fast Recovery". A series of congestion control mechanisms, such as the (Fast Recovery) algorithm, implement congestion control for data transmission. Taking TCP-Reno as an example, the slow start mainly adjusts the congestion window (CWnd, Congestion Window) according to the network condition to gradually increase the amount of data sent each time, so as to avoid congestion when a large number of data packets are sent from the beginning, CWnd presents an exponential form. Upward; the basic idea of congestion avoidance is to adjust CWnd to increase linearly when CWnd reaches the preset slow start threshold in slow start, to avoid network congestion caused by excessive growth; fast retransmission is every time the receiver receives an out of order A duplicate acknowledgment is sent immediately after the message segment. As long as the sender receives three consecutive acknowledgments, it should immediately retransmit the segment that has not been received by the other party without waiting for the retransmission timer to expire; fast recovery means when When the sender continuously receives three duplicate acknowledgments, the slow start threshold is halved to prevent congestion on the network.
传统的TCP拥塞控制方案是针对于终端位置固定,传输网络环境情况相对稳定的应用场景提出的,对提高有线网络的性能有较大的优势。然而,随着移动互联网技术和无线通信技术的发展,终端可以通过蜂窝网接入互联网,而蜂窝网中基站较多,终端接入数量不定时发生变化,终端不时切换基站现象频繁,以及由于无线信道环境、无线网络状况,以及终端的移动情况,蜂窝网终端的无线侧传输状况瞬息万变。对于上层TCP,目前的机制具有一定尝试性和盲目性,严重时会有伪超时现象出现,造成无线资源的浪费,降低了无线通信系统的吞吐率。The traditional TCP congestion control scheme is proposed for the application scenario where the terminal location is fixed and the transmission network environment is relatively stable, which has a great advantage for improving the performance of the wired network. However, with the development of mobile internet technology and wireless communication technology, terminals can access the Internet through a cellular network, and there are many base stations in the cellular network, the number of terminal accesses changes from time to time, the terminal frequently switches base stations from time to time, and because of wireless The channel environment, the state of the wireless network, and the movement of the terminal, the wireless side transmission status of the cellular terminal is rapidly changing. For the upper layer TCP, the current mechanism has certain tentative and blindness. In severe cases, there will be a pseudo timeout phenomenon, which causes waste of wireless resources and reduces the throughput rate of the wireless communication system.
另外,现有的无线网络和TCP/应用服务器(比如视频基于HTTP的动态自适应多媒体流(DASH,Dynamic Adaptive Streaming over HTTP))的调控机制是完全分开透明设计的,两者之间不直接进行交互适配,比如TCP服务器窗口调控是根据丢包以及TCP层的吞吐量估计进行设定的。而在无线网络中,TCP数据包的丢失可能是由无线侧引发的,无线链路是端到端TCP链路的一部分,无线链路的质量也会影响TCP吞吐量。但是,由于传输距离,以及协议层次等的差异,慢速的TCP调控难以有效地适配相比之下非常动态变化的无线信道和无线速率。对于应用端,以视频服务器为例,当前的视频服务器的码率调控是基于端到端的业务速率进行速率估计和码率调整的,同样存在着跟实际可用无线环境的不匹配的问题,从而影响了数据传输效率,降低了无线网络的网络资源利用率。In addition, the existing wireless network and TCP/application server (such as video-based Dynamic Adaptive Streaming over HTTP (DASH)) are completely transparent and are not directly implemented between the two. Interaction adaptation, such as TCP server window control, is set based on packet loss and TCP layer throughput estimates. In wireless networks, the loss of TCP packets may be caused by the wireless side. The wireless link is part of the end-to-end TCP link, and the quality of the wireless link also affects TCP throughput. However, due to differences in transmission distances, protocol levels, etc., slow TCP regulation is difficult to effectively adapt to very dynamic wireless channels and wireless rates. For the application side, taking the video server as an example, the current rate adjustment of the video server is based on the end-to-end service rate for rate estimation and rate adjustment, and there is also a problem of mismatch with the actual available wireless environment, thereby affecting The data transmission efficiency reduces the network resource utilization of the wireless network.

具体实施方式detailed description
为了使数据传输控制与实时的无线网络环境状态相匹配,以提高无线资源的利用效率和无线通信系统的吞吐率,本发明实施例提供了一种信息传输优化方法、装置、系统和设备。In order to match the data transmission control with the real-time wireless network environment state to improve the utilization efficiency of the wireless resource and the throughput rate of the wireless communication system, the embodiment of the invention provides an information transmission optimization method, device, system and device.
以下结合说明书附图对本发明的优选实施例进行说明,应当理解,此处所描述的优选实施例仅用于说明和解释本发明,并不用于限定本发明,并且在不冲突的情况下,本发明中的实施例及实施例中的特征可以相互组合。The preferred embodiments of the present invention are described in conjunction with the accompanying drawings, and the preferred embodiments described herein are intended to illustrate and explain the invention, and not to limit the invention, and The embodiments and the features in the embodiments can be combined with each other.
根据传统的TCP,TCP服务器利用各种算法计算当一个数据包传输出去后到收到其确认指令之间所花时间,然后,再利用这个信息来推算连接可以支持的最高传输速率,并据此调整向终端发送的数据包的发送速率。According to the traditional TCP, the TCP server uses various algorithms to calculate the time taken between the transmission of a packet and the receipt of its acknowledgment command, and then uses this information to estimate the maximum transmission rate that the connection can support, and accordingly Adjust the sending rate of packets sent to the terminal.
发明人发现,由于传统的TCP拥塞控制方案是针对于终端位置固定,传输网络环境情况相对稳定的应用场景提出的,其对提高有线网络的性能有较大的优势,而将其应用于无线通信网络中时,由于无线信道环境、无线网络状况,以及终端的移动情况,蜂窝网终端的无线侧传输状况瞬息万变,因此,现有的数据传输方法与实时的无线网络环境状态相匹配,从而降低了网络资源的利用效率以及无线通信系统的吞吐率。因此,如何使应用服务器根据终端当前接入网络的无线网络环境状况来进行拥塞控制成为现有技术中亟待解决的技术问题之一。The inventor has found that the traditional TCP congestion control scheme is proposed for the application scenario where the terminal location is fixed and the transmission network environment is relatively stable, which has a great advantage for improving the performance of the wired network, and is applied to the wireless communication. In the network, due to the wireless channel environment, the state of the wireless network, and the movement of the terminal, the wireless side transmission status of the cellular network terminal is rapidly changing. Therefore, the existing data transmission method matches the real-time wireless network environment state, thereby reducing the The utilization efficiency of network resources and the throughput of wireless communication systems. Therefore, how to enable the application server to perform congestion control according to the wireless network environment condition in which the terminal currently accesses the network has become one of the technical problems to be solved in the prior art.
有鉴于此,本发明实施例提供了一种信息传输方法,基于无线网络环境确定数据传输控制信息;UE或应用服务器基于数据传输控制信息对自身发送给对端的数据包进行控制。In view of this, an embodiment of the present invention provides an information transmission method for determining data transmission control information based on a wireless network environment; the UE or the application server controls a data packet that is sent to the peer end based on the data transmission control information.

The transmission control information controls the packets that are sent to the application server itself.
另一种实现方式是:由UE当前接入的无线接入网络设备将无线网络环境信息发送给UE,UE根据接收到的无线网络环境信息确定相应的数据传输控制信息并发送给应用服务器,使得应用服务器可以根据接收到的数据传输控制信息对自身发送给UE的数据包进行控制。Another implementation manner is: the radio access network device currently accessed by the UE sends the radio network environment information to the UE, and the UE determines corresponding data transmission control information according to the received radio network environment information, and sends the information to the application server, so that The application server can control the data packets that are sent to the UE according to the received data transmission control information.

The server provides data transmission control information for the user to perform data transmission control, so that the application server can adjust the data transmission between itself and the UE according to the received data transmission control information, so that the data transmission can follow the wireless environment information. The changes are changed in real time to improve the utilization efficiency of wireless resources and the throughput of wireless communication systems.

步骤S32中涉及的可用带宽信息可以根据小区拥塞信息、UE信道质量信息和实时空口速率确定出。The available bandwidth information involved in step S32 may be determined according to cell congestion information, UE channel quality information, and real-time air interface rate.
为例更好地理解本发明实施例,以下以应用服务器为TCP服务器为例,对本发明实施例的具体实施过程进行说明,相应地,如果应用服务器为TCP服务器,则初始链接建立阶段可以对应于TCP慢启动阶段,数据传输阶段可以对应于拥塞避免阶段,以下分别进行说明。For a better understanding of the embodiments of the present invention, the following describes the specific implementation process of the embodiment of the present invention by using the application server as a TCP server. Accordingly, if the application server is a TCP server, the initial link establishment phase may correspond to In the TCP slow start phase, the data transmission phase may correspond to the congestion avoidance phase, which is described separately below.
如图4a所示,为TCP慢启动阶段,数据传输优化方法的实施流程示意图,可以包括以下步骤:As shown in FIG. 4a, the schematic diagram of the implementation process of the data transmission optimization method in the TCP slow start phase may include the following steps:
S41、UE与TCP服务器建立链接。S41. The UE establishes a link with the TCP server.
具体实施时,UE与TCP服务器之间进行三次握手以建立TCP链接。During specific implementation, the UE and the TCP server perform a three-way handshake to establish a TCP link.
S42、无线接入设备(可以称为RAN)识别TCP初始连接。S42. A wireless access device (which may be referred to as a RAN) identifies a TCP initial connection.
本步骤中,RAN识别TCP初始链接,较佳地,无线接入网络设备可以通过深度包检测(DPI)等方法进行识别,本发明实施例中不进行限定。In this step, the RAN identifies the TCP initial link. Preferably, the radio access network device can be identified by a method such as deep packet inspection (DPI), which is not limited in the embodiment of the present invention.
S43、RAN生成TCP初始发送窗口。S43. The RAN generates a TCP initial transmission window.
具体实施时,RAN可以根据无线接入网侧缓存空间总大小与填充所期待时间(可以根据实际需要设置)之比得到速率V1,并根据小区拥塞信息和UE测量的信道质量信息得到可用带宽信息,并根据可用带宽确定速率V2,进一步来说,根据小区拥塞信息可以得出小区空余的空口资源数量(RB,Radio Block),根据UE的信道质量(比如信道质量指示符(CQI,Channel  Quality Indicator))可以算出UE在RB资源上传输所使用的调制编码方案(MCS,Modulation Codeing Scheme),从而估算出UE可能的初始速率,并根据(V1+V2)确定TCP初始发送窗口。In a specific implementation, the RAN may obtain the rate V1 according to the ratio of the total size of the buffer space on the radio access network to the expected time of filling (which may be set according to actual needs), and obtain available bandwidth information according to the cell congestion information and the channel quality information measured by the UE. And determining the rate V2 according to the available bandwidth. Further, according to the cell congestion information, the number of air interface resources (RB, Radio Block) of the cell may be obtained according to the channel quality of the UE (such as a channel quality indicator (CQI, Channel). The quality indicator) can calculate the modulation coding scheme (MCS) used by the UE to transmit on the RB resource, thereby estimating the initial rate of the UE, and determining the initial TCP transmission window according to (V1+V2).
S44、RAN将生成的TCP初始发送窗口分别发送给TCP服务器和UE。S44. The RAN sends the generated initial TCP sending window to the TCP server and the UE, respectively.
S45、TCP服务器和UE以初始发送窗口进行数据包发送。S45. The TCP server and the UE send the data packet in an initial transmission window.
由此,在TCP慢启动阶段,TCP服务器可以根据初始发送窗口进行数据包发送,实现一次性填充一定比例的缓存空间和利用一定比例的无线可调度资源,避免慢启动阶段造成无线资源浪费。Therefore, in the slow start phase of the TCP, the TCP server can send the data packet according to the initial sending window, and fill a certain proportion of the cache space and utilize a certain proportion of the wireless schedulable resources at one time to avoid waste of wireless resources in the slow start phase.
如图5a所示,为拥塞避免阶段,数据传输优化方法的实施流程示意图,可以包括以下步骤:As shown in FIG. 5a, for the congestion avoidance phase, a schematic diagram of an implementation process of the data transmission optimization method may include the following steps:
S51、RAN生成TCP窗口调整指示信息。S51. The RAN generates TCP window adjustment indication information.
本步骤中,在UE与TCP服务器进行数据传输过程中,RAN根据RAN侧的实时缓存变化和可用带宽生成TCP发送窗口指示信息。In this step, during data transmission between the UE and the TCP server, the RAN generates TCP transmission window indication information according to the real-time cache change and the available bandwidth on the RAN side.
在拥塞避免阶段,可用带宽可以根据小区拥塞信息、UE信道质量信息和实时空口速率确定出。In the congestion avoidance phase, the available bandwidth may be determined according to cell congestion information, UE channel quality information, and real-time air interface rate.
例如,RAN可以根据无线侧缓存剩余空间大小(缓存中未被数据占用部分)与填充所期待时间(可以根据实际需要设置)之比得到V3,并根据V3和可用带宽之和确定TCP发送窗口调整指示信息。For example, the RAN may obtain V3 according to the ratio of the remaining space of the wireless side buffer (the portion of the buffer that is not occupied by the data) and the expected time of filling (which may be set according to actual needs), and determine the TCP transmission window adjustment according to the sum of V3 and the available bandwidth. Instructions.
具体地,TCP发送窗口指示信息可以为相对值(该值为相对于上一时刻发送窗口的调整值,根据该值,应用服务器和UE可以确定当前时刻的TCP发送窗口相对于上一时刻的TCP发送窗口的变化值),也可以为绝对值(即应用服务器和UE调整后的TCP)。Specifically, the TCP sending window indication information may be a relative value (the value is an adjustment value of the sending window with respect to the last time, according to which the application server and the UE may determine the TCP sending window of the current time relative to the TCP of the previous moment. The change value of the send window) can also be an absolute value (ie, the application server and the UE adjusted TCP).
以TCP发送窗口指示信息为相对值为例:TCP发送窗口指示信息一种可能的形式为增加可用带宽指示(比如+1),即增加可用带宽的值;另外一种可能的形式为减少可用带宽指示(比如-1),即减少可用带宽的值。或者, 又一种可能的形式为增加(比如+1),或者减少TCP发送窗口(比如-1)等等,本发明实施例不再一一列举。The TCP transmission window indication information is a relative value: a possible form of the TCP transmission window indication information is to increase the available bandwidth indication (such as +1), that is, increase the value of the available bandwidth; another possible form is to reduce the available bandwidth. An indication (such as -1) that reduces the value of the available bandwidth. Or, Yet another possible form is to increase (such as +1), or to reduce the TCP transmission window (such as -1), etc., which are not enumerated in the embodiments of the present invention.
S52、RAN分别向UE和TCP服务器发送TCP发送窗口调整指示信息。S52. The RAN sends TCP transmission window adjustment indication information to the UE and the TCP server, respectively.
S53、UE和TCP服务器在下一时刻根据调整后的TCP发送窗口进行数据包发送。S53. The UE and the TCP server perform data packet transmission according to the adjusted TCP transmission window at the next moment.
由此,在TCP拥塞避免阶段,TCP服务器可以根据TCP窗口调整指示信息进行数据包发送,具体的,根据V3和可用带宽的不同组合,可以有多种实施方式。Therefore, in the TCP congestion avoidance phase, the TCP server can perform data packet transmission according to the TCP window adjustment indication information. Specifically, according to different combinations of V3 and available bandwidth, there may be multiple implementation manners.
第一种实施方式、可用带宽波动大:当可用带宽迅速增强(例如在连续几个时刻,可用带宽均增大,且变化率大于等于预设阈值)或者剩余缓存空间大于预设阈值时,则可以指示TCP服务器增大TCP发送窗口或者数据包发送速率;当可用带宽低于一定阈值时或者剩余缓存空间不大于预设阈值时,则可以指示TCP服务器减小TCP发送窗口或者数据包发送速率等等。而如果在一段时间内,可用带宽比较稳定(即可用带宽在预设范围内波动),则可以先指示TCP服务器增大TCP发送窗口或者数据包发送速率,提高缓存的利用率,当缓存空间的利用率达到预设阈值后,再指示TCP服务器已与可用带宽相匹配的数据包发送速率或者TCP发送窗口进行数据包发送,最大程度上避免了无线资源的浪费,从而能够获得更大的系统吞吐率,如图6a所示。In the first implementation manner, the available bandwidth fluctuates greatly: when the available bandwidth is rapidly enhanced (for example, when the available bandwidth is increased for several consecutive times, and the rate of change is greater than or equal to the preset threshold) or the remaining buffer space is greater than the preset threshold, then The TCP server may be instructed to increase the TCP sending window or the data packet sending rate; when the available bandwidth is lower than a certain threshold or the remaining buffer space is not greater than a preset threshold, the TCP server may be instructed to reduce the TCP sending window or the data packet sending rate, etc. Wait. If the available bandwidth is stable for a period of time (that is, the bandwidth can fluctuate within the preset range), the TCP server can be instructed to increase the TCP transmission window or the packet transmission rate, thereby improving the cache utilization rate. After the usage reaches the preset threshold, the TCP server indicates that the TCP packet has been matched with the available bandwidth or the TCP transmission window is used for packet transmission. This avoids the waste of wireless resources and can achieve greater system throughput. The rate is shown in Figure 6a.
具体实施时,如果缓存空间大小变化值(即相邻两个时刻缓存空间大小之间的差值)趋于0,并且缓存绝对值大于0,则确定TCP数据包发送速率与可用带宽相匹配。为了获得与可用带宽更加匹配的TCP数据包发送速率,具体实施时,本发明实施例中,还可以根据缓存空间填充率和缓存空间大小变化值在动态指示TCP服务器的数据包发送速率或者TCP发送窗口。 In a specific implementation, if the cache space size change value (that is, the difference between the cache time sizes of two adjacent moments) tends to 0, and the cache absolute value is greater than 0, it is determined that the TCP packet transmission rate matches the available bandwidth. In order to obtain a TCP packet transmission rate that is more matched with the available bandwidth, in the embodiment of the present invention, the data packet transmission rate of the TCP server or the TCP transmission may be dynamically indicated according to the buffer space filling rate and the buffer space size change value. window.
基于此,本发明实施例中,步骤S11还可以按照以下公式确定应用服务器侧的数据包发送速率:
Figure PCTCN2017096852-appb-000005
其中:k为预设值,Vmac实时空口速率,Δbuffer为缓存空间大小变化值,BufferSize为缓存空间总大小。
Based on this, in the embodiment of the present invention, step S11 may further determine a data packet sending rate on the application server side according to the following formula:
Figure PCTCN2017096852-appb-000005
Among them: k is the default value, V mac real-time air interface rate, Δbuffer is the cache space size change value, BufferSize is the total cache space size.
其中,k为优化因子,具体实施时,按照以下方法确定k:如果所述缓存空间填充率小于第一阈值时,则确定所述k为大于1的数值;如果所述缓存空间填充率不小于所述第一阈值且所述缓存空间填充率小于第二阈值,则确定所述k为1;如果所述缓存空间填充率不小于所述第二阈值,则确定k为小于1的数值。Where k is an optimization factor. In specific implementation, k is determined according to the following method: if the buffer space filling rate is less than the first threshold, determining that k is a value greater than 1; if the buffer space filling rate is not less than And determining, by the first threshold, that the buffer space filling rate is less than the second threshold, determining that k is 1; if the buffer space filling rate is not less than the second threshold, determining that k is a value less than 1.
例如,具体实施时,如果缓存空间填充率小于等于50%,由于缓存空间填充率较低,则需要更快地填充缓存至一定合理值,则可以确定k为大于1的数值,例如确定k为1.3,而如果缓存空间填充率大于50%而小于80%,则说明缓存空间填充率处于合理范围内,则可以确定k为1,而如果缓存空间填充率大于等于80%,则说明缓存空间有溢出风险,则可以确定k为小于1的数值,例如确定k为0.8。For example, in a specific implementation, if the cache space filling rate is less than or equal to 50%, since the cache space filling rate is low, the cache needs to be filled to a reasonable value faster, and it can be determined that k is a value greater than 1, for example, determining k is 1.3, and if the cache space fill rate is greater than 50% and less than 80%, then the cache space fill rate is within a reasonable range, then it can be determined that k is 1, and if the cache space fill rate is greater than or equal to 80%, then the cache space has For spillover risk, it can be determined that k is a value less than 1, for example, it is determined that k is 0.8.
在一些实施例中,还可以根据TCP发包速率和缓存空间大小变化值获取实时空口速率,例如,通过上一时刻TCP发送速率减去上一时刻缓存空间大小变化值可以获得此时的实时空口速率。In some embodiments, the real-time air interface rate can also be obtained according to the TCP packet sending rate and the buffer space size change value. For example, the real-time air interface rate can be obtained by subtracting the previous time cache space size change value from the previous time TCP transmission rate. .
在一些实施例中,在步骤S12中,无线接入网络设备可以通过以下任一种方式将数据传输控制信息提供给应用服务器:In some embodiments, in step S12, the radio access network device may provide the data transmission control information to the application server in any of the following manners:

在第二种实现方式中,为了解决应用服务器根据终端当前接入网络的无线网络环境状况来进行拥塞控制的问题,首先需要解决的技术问题是无线接入网络设备如何将实时的无线网络环境信息发送给UE,以使UE据此确定与应用服务器之间的数据传输控制信息。在一些实施例中,UE还可以将确定出的数据传输控制信息发送给应用服务器,使得应用服务器能够根据接收到的数据传输控制信息对自身与UE之间的数据传输进行相应的调整,以使数据传输能够随着无线环境信息的变化而实时变化,提高数据传输性能。In the second implementation manner, in order to solve the problem that the application server performs congestion control according to the wireless network environment state in which the terminal currently accesses the network, the first technical problem to be solved is how the wireless access network device will perform real-time wireless network environment information. The UE is sent to the UE to determine data transmission control information with the application server accordingly. In some embodiments, the UE may further send the determined data transmission control information to the application server, so that the application server can adjust the data transmission between itself and the UE according to the received data transmission control information, so that Data transmission can change in real time as the information of the wireless environment changes, improving data transmission performance.
为此,本发明实施例提供了一种无线接入网络设备侧实施的信息传输方法,如图10a所示,可以包括以下步骤:To this end, an embodiment of the present invention provides a method for transmitting information implemented by a device on a radio access network, as shown in FIG. 10a, which may include the following steps:
S101、无线接入网络设备向UE发送无线网络环境信息。S101. The wireless access network device sends the wireless network environment information to the UE.
其中,无线网络环境信息可以但不限于包括以下至少一项:所述UE的可用带宽、UE在无线接入网络侧的缓存信息、小区拥塞信息。The wireless network environment information may include, but is not limited to, at least one of the following: an available bandwidth of the UE, a cache information of the UE on the radio access network side, and cell congestion information.
在一些实施例中,无线接入网络设备可以根据当前接入的用户数量确定UE的可用带宽;或者无线接入网络设备根据所述UE反馈的信道质量新确定UE的可用带宽等等。In some embodiments, the radio access network device may determine the available bandwidth of the UE according to the number of users currently accessed; or the radio access network device may newly determine the available bandwidth of the UE or the like according to the channel quality fed back by the UE.
具体实施时,无线接入网络设备可以周期性地向UE发送无线网络环境信息,或者无线接入网络设备在无线网络环境发生变化时向UE发送无线网络环境信息,或者无线接入网络设备还可以在UE的触发下向UE发送无线网络环境信息,本发明实施例对此不进行限定。In a specific implementation, the wireless access network device may periodically send the wireless network environment information to the UE, or the wireless access network device sends the wireless network environment information to the UE when the wireless network environment changes, or the wireless access network device may also The wireless network environment information is sent to the UE under the trigger of the UE, which is not limited in this embodiment of the present invention.

本步骤中,UE可以将自身当前正在使用业务的业务信息上报给无线接入网络设备,例如,UE可以将当前正在播放视频在UE本地的缓存信息上 报给无线接入网络设备。In this step, the UE may report the service information of the service currently being used by the UE to the radio access network device. For example, the UE may play the video currently being played on the local cache information of the UE. Report to the wireless access network device.
具体实施时,如果UE与无线接入网络设备之间建立无线资源控制(RRC)连接,则可以通过RRC信令向无线接入网络设备发送自身当前正在使用业务的业务信息,如果UE与应用服务器之间通过无线接入网络设备建立了数据连接,则UE可以在通过无线接入网络设备向应用服务器传输的数据包中携带自身当前正在使用业务的业务信息。In a specific implementation, if a radio resource control (RRC) connection is established between the UE and the radio access network device, the service information of the service currently being used by the radio access network device may be sent to the radio access network device by using RRC signaling, if the UE and the application server A data connection is established between the wireless access network device, and the UE can carry the service information of the service currently being used by the UE in the data packet transmitted to the application server through the wireless access network device.
S101”、根据接收到的业务信息,确定向所述UE发送的无线网络环境信息。S101. The wireless network environment information sent to the UE is determined according to the received service information.
以无线接入网络设备接收到的业务信息为UE本地的缓存信息为例,如果无线接入网络设备根据UE本地的缓存信息确定UE本地的缓存低于预设阈值时,则可以增大为UE的可用带宽,并将调整后的UE的可用带宽信息发送给UE。For example, if the service information received by the radio access network device is the local cache information of the UE, if the radio access network device determines that the local cache of the UE is lower than a preset threshold according to the local cache information of the UE, the UE may be increased to the UE. The available bandwidth is sent to the UE for the adjusted available bandwidth information of the UE.
具体实施时,如果无线接入设备与UE之间建立的RRC连接,则无线接入网络设备可以通过与UE之间的空口信令向UE发送无线网络环境信息,如果UE通过无线接入网络设备与应用服务器建立了数据连接,则无线接入网络设备还可以通过在与UE之间传输的数据包中携带无线网络环境信息。In a specific implementation, if the RRC connection is established between the radio access device and the UE, the radio access network device may send the radio network environment information to the UE by using air interface signaling with the UE, if the UE accesses the network device through the radio. The data connection is established with the application server, and the wireless access network device can also carry the wireless network environment information by using the data packet transmitted between the UE and the UE.
如图10b所示,其为UE与无线接入设备通过RRC信令传输无线网络环境信息的实施流程示意图,可以包括以下步骤:As shown in FIG. 10b, it is a schematic flowchart of an implementation process for transmitting a radio network environment information by using a RRC signaling between a UE and a radio access device, and may include the following steps:
S1001、UE向无线接入网络设备发送当前正在使用业务的业务信息。S1001: The UE sends the service information of the service currently being used to the radio access network device.
具体实施时,UE可以通过新建RRC信令向无线接入网络设备发送当前正在使用业务的业务信息,例如,该业务信息可以为UE当前正在播放视频的缓存大小。In a specific implementation, the UE may send the service information of the currently used service to the radio access network device by using the RRC signaling. For example, the service information may be a buffer size of the video currently being played by the UE.
S1002、无线接入网络设备确定当前的无线网络环境信息。S1002: The wireless access network device determines current wireless network environment information.
例如,无线接入网络设备根据UE当前的信道质量或者小区拥塞信息以 及UE提供的业务信息确定UE的可用带宽,例如,无线接入网络设备确定增大UE的可用带宽。For example, the radio access network device is based on the current channel quality of the UE or the cell congestion information. And the service information provided by the UE determines the available bandwidth of the UE, for example, the radio access network device determines to increase the available bandwidth of the UE.
S1003、无线接入网络设备向UE发送无线网络环境信息。S1003. The radio access network device sends the wireless network environment information to the UE.
本步骤中,无线接入网络设备可以通过扩展已有的RRC信令携带无线网络环境信息。In this step, the radio access network device can carry the wireless network environment information by extending the existing RRC signaling.
具体地,如果无线接入网络设备使用空口信令向UE发送无线网络环境信息,则无线接入网络设备可以使用层1(L1)信令、层2(L2)信令或者层3(L3)信令。如L2信令中的MAC CE信令,或者L3信令中的RRC信令。由于现有已定义的信令中并没有发送无线网络环境信息的信令,因此,本发明实施例中,可以通过扩展MAC CE信令来传递无线网络环境信息。分别如图11a和图11b所示,其为现有的MAC数据包头格式,其中,逻辑信道指示符(LCID)用于指示逻辑信道上传输的信息,下行信令中,01011~10111为预留位,因此,本发明实施例中,可以扩展下行信道(DL)LCID预留位用于通知UE DL网络环境信息(如UE的可用带宽或者网络拥塞信息或者UE在无线接入网络侧的缓存信息等),例如,具体实施时,可以使用预留位10111指示无线网络环境信息。Specifically, if the radio access network device sends the radio network environment information to the UE by using air interface signaling, the radio access network device may use layer 1 (L1) signaling, layer 2 (L2) signaling, or layer 3 (L3). Signaling. For example, MAC CE signaling in L2 signaling, or RRC signaling in L3 signaling. The signaling of the wireless network environment is not transmitted in the existing defined signaling. Therefore, in the embodiment of the present invention, the wireless network environment information may be transmitted by extending the MAC CE signaling. As shown in FIG. 11a and FIG. 11b respectively, it is an existing MAC data packet header format, wherein a logical channel indicator (LCID) is used to indicate information transmitted on a logical channel, and in the downlink signaling, 01011 to 10111 are reserved. Therefore, in the embodiment of the present invention, the downlink channel (DL) LCID reserved bit may be extended to notify the UE of the DL network environment information (such as the available bandwidth of the UE or the network congestion information or the cache information of the UE on the radio access network side). Etc.) For example, in a specific implementation, the reserved bit 10111 may be used to indicate wireless network environment information.
同样,对于UE向无线接入网络设备发送的业务信息也可以通过空口信令发送。其中,针对上行信令,01011-10110为预留位,因此,本发明实施例中,可以扩展UL LCID(上行逻辑信道指示符)预留位用于UL业务信息(例如UE侧的视频缓存大小)的通知,例如,具体实施时,可以使用预留位10101指示UE的业务信息。Similarly, the service information sent by the UE to the radio access network device may also be sent through air interface signaling. For the uplink signaling, 01011-10110 is a reserved bit. Therefore, in the embodiment of the present invention, the UL LCID (uplink logical channel indicator) reserved bit may be extended for UL service information (for example, the video buffer size of the UE side). The notification of the UE, for example, may be used to indicate the service information of the UE using the reserved bit 10101.
需要说明的是,上述使用空口信令中的预留位发送无线网络环境信息或者业务信息仅为本发明实施例一种较佳的实施方法,其不构成对本发明的限定。It should be noted that the above-mentioned use of the reserved bits in the air interface signaling to transmit the wireless network environment information or the service information is only a preferred implementation method of the embodiment of the present invention, which does not constitute a limitation of the present invention.

In some embodiments, the wireless access network device can carry wireless network environment information through user plane data packets transmitted between the UEs, where the user plane data packets can include MAC data packets or RLC data packets.

S1011、UE向无线接入网络设备发送当前正在使用业务的业务信息。S1011: The UE sends the service information of the service currently being used to the radio access network device.
如果UE与应用服务器之间通过无线接入网络设备建立数据连接并基于建立的数据连接进行数据传输,UE可以通过传输的数据包向无线接入网络设备发送当前正在使用业务的业务信息,例如,该业务信息可以为UE当前正在播放视频的缓存大小。If the UE establishes a data connection with the application server through the wireless access network device and performs data transmission based on the established data connection, the UE may send the service information of the currently used service to the wireless access network device by using the transmitted data packet, for example, The service information may be a buffer size of a video currently being played by the UE.

由于相关技术的数据包中并没有携带无线网络环境信息的字段,因此,本发明实施例中需要对无线接入网络设备与UE之间传输的用户面数据包进行扩展以携带无线网环境信息,例如,可以使用现有的用户面数据包中的保留字段携带无线网络环境信息或者在用户面数据包中新增字段携带无线网络环境信息等等。The data packet of the related art does not carry the field of the wireless network environment information. Therefore, in the embodiment of the present invention, the user plane data packet transmitted between the wireless access network device and the UE needs to be extended to carry the wireless network environment information. For example, the reserved field in the existing user plane data packet can be used to carry the wireless network environment information or add a new field in the user plane data packet to carry the wireless network environment information and the like.

由于相关技术的数据包中并没有携带无线网络环境信息的字段,因此,本发明实施例中需要对无线接入网络设备与UE之间传输的用户面数据包进行扩展以携带无线网环境信息,例如,可以使用现有的用户面数据包中的保留字段携带无线网络环境信息或者在用户面数据包中新增字段携带无线网络环境信息等等。The data packet of the related art does not carry the field of the wireless network environment information. Therefore, in the embodiment of the present invention, the user plane data packet transmitted between the wireless access network device and the UE needs to be extended to carry the wireless network environment information. For example, the reserved field in the existing user plane data packet can be used to carry the wireless network environment information or add a new field in the user plane data packet to carry the wireless network environment information and the like.

相应地,本发明实施例还提供了一种UE侧实施的信息传输方法,如图12a所示,可以包括以下步骤:Correspondingly, the embodiment of the present invention further provides an information transmission method implemented by the UE side, as shown in FIG. 12a, which may include the following steps:
S121、接收无线接入网络设备发送的无线网络环境信息。S121. Receive wireless network environment information sent by a wireless access network device.
例如,无线接入网络设备可以使用空口信令或者与UE之间传输的数据包向UE发送无线网络环境信息。无线接入网络设备向UE发送无线网络环境信息的实施流程可以参见上述无线接入网络设备侧实施的信息传输方法,这里不再赘述。For example, the wireless access network device can transmit wireless network environment information to the UE using air interface signaling or data packets transmitted between the UEs. For the implementation process of the wireless access network device to send the wireless network environment information to the UE, refer to the information transmission method implemented by the wireless access network device side, and details are not described herein again.
S122、根据接收到的无线网络环境信息确定数据传输控制信息。S122. Determine data transmission control information according to the received wireless network environment information.
在获得了无线接入设备发送的无线网络环境信息后,UE根据接收到的无线网络环境信息确定自身与应用服务器之间的数据传输控制信息。以无线网络环境中的可用带宽信息为例,其中,UE的可用带宽可以根据UE信 道环境,小区拥塞程度等信息来确定,如果可用带宽增大,则UE与应用服务器之间交互传输控制信息来增大数据包发送和接收窗口或者选择更高的数据发送和接收码率,如果可用带宽减小,则UE与应用服务器之间交互传输控制信息来减少数据包发送或接收窗口或者选择更低的数据发送和接收码率;或者根据RAN侧缓存大小和变化来调整发送或接收窗口或者接收码率,如果缓存低于某个门限左右(比如50%等),且缓存在减少,则UE与应用服务器之间交互传输控制信息来增加数据发送速率或者选择较高的数据接收码率,如果缓存高于某个门限左右(比如80%等),且缓存在增加,则UE与应用服务器之间交互传输控制信息来减少数据发送速率或者选择较低的数据接收码率;或者UE根据无线网络环境中的小区拥塞信息来调整接收或发送窗口大小或者数据接收码率等等,本发明实施例中不再一一列举。After obtaining the wireless network environment information sent by the wireless access device, the UE determines data transmission control information between itself and the application server according to the received wireless network environment information. Take the available bandwidth information in the wireless network environment as an example, where the available bandwidth of the UE may be based on the UE information. Information such as the channel environment, the degree of congestion of the cell, etc., if the available bandwidth is increased, the UE and the application server exchange control information to increase the data packet transmission and reception window or select a higher data transmission and reception code rate, if The available bandwidth is reduced, and the UE and the application server exchange control information to reduce the data packet transmission or reception window or select a lower data transmission and reception code rate; or adjust the transmission or reception window according to the RAN side buffer size and change. Or receiving the code rate. If the buffer is lower than a certain threshold (such as 50%, etc.), and the buffer is decreasing, the UE and the application server exchange control information to increase the data transmission rate or select a higher data reception rate. If the cache is higher than a certain threshold (such as 80%, etc.), and the buffer is increasing, the UE and the application server exchange control information to reduce the data transmission rate or select a lower data reception rate; or the UE according to Cell congestion information in a wireless network environment to adjust the receive or transmit window size or data receive rate, etc. Not enumerated example embodiment of the present invention.
S123、将确定出的数据传输控制信息发送给应用服务器。S123. Send the determined data transmission control information to the application server.
本步骤中,将步骤S122中确定出的数据传输控制信息发送给应用服务器,使得应用服务器根据UE侧确定出的数据传输控制信息调整自身的数据传输速率或者发送窗口。In this step, the data transmission control information determined in step S122 is sent to the application server, so that the application server adjusts its own data transmission rate or transmission window according to the data transmission control information determined by the UE side.
例如,视频服务器根据UE发送的数据接收码率,调整自身向UE发送视频数据的码率;又如,TCP服务器根据UE发送的接收窗口大小以及自身维护的拥塞窗口大小确定自身向UE发送TCP包的发送窗口大小等等。For example, the video server adjusts the code rate of the video data transmitted by the UE according to the data received by the UE. For example, the TCP server determines that the TCP packet is sent to the UE according to the size of the receiving window sent by the UE and the size of the congestion window maintained by the UE. The send window size and so on.
具体实施时,本发明实施例提供的UE侧实施的信息传输方法,在实施步骤S121之前,还可以包括以下步骤:向无线接入网络设备发送当前正在使用业务的业务信息,以使无线接入网络设备根据接收到的业务信息确定向UE发送的无线网络环境信息。In a specific implementation, the information transmission method implemented by the UE side in the embodiment of the present invention may further include the following steps: sending the service information of the currently used service to the radio access network device to enable the radio access before performing step S121. The network device determines the wireless network environment information sent to the UE according to the received service information.
例如,UE侧将当前正在播放视频在UE本地的缓存信息发送给无线接入网络设备,无线接入网络设备根据接收到的缓存信息确定其小于预设阈 值时,可以增大分配给UE的可用带宽,相应地,UE在接收到无线接入网络设备返回的无线网络环境信息后,可以调大自身的数据接收窗口或者数据接收码率,并将调整的数据接收窗口发送给TCP服务器,使得TCP服务器根据UE侧的数据接收窗口以及自身维护的拥塞窗口来调整自身的数据发送窗口,或者将调整后的数据接收码率发送给视频服务器,使得TCP服务器或者视频服务器根据接收到的数据传输码率来调整自身向UE发送视频数据的码率。For example, the UE side sends the cache information of the currently playing video in the UE to the radio access network device, and the radio access network device determines that it is less than the preset threshold according to the received cache information. When the value is used, the available bandwidth allocated to the UE may be increased. Accordingly, after receiving the wireless network environment information returned by the radio access network device, the UE may increase its own data receiving window or data receiving code rate, and adjust The data receiving window is sent to the TCP server, so that the TCP server adjusts its own data sending window according to the data receiving window of the UE side and the congestion window maintained by itself, or sends the adjusted data receiving code rate to the video server, so that the TCP server Or the video server adjusts the code rate of the video data that it sends to the UE according to the received data transmission code rate.
在另外一个实施例中,UE在执行步骤S121之前,方法还可以包括以下步骤:向所述无线接入网络设备发送业务优化请求。在一些实施例中,在向所述无线接入网络设备发送业务优化请求之前,方法还可以包括:确定满足预设的触发条件。In another embodiment, before performing step S121, the method may further include the step of: sending a service optimization request to the radio access network device.

为了更好的理解本发明实施例,以下结合UE、无线接入网络设备和应 用服务器之间的交互流程对本发明实施例的具体实施方式进行说明。如图12b所示,可以包括以下步骤:In order to better understand the embodiments of the present invention, the following combines UE, radio access network equipment, and A specific implementation manner of an embodiment of the present invention is described by using an interaction process between servers. As shown in Figure 12b, the following steps can be included:
S1201、UE向无线接入网络设备发送当前正在进行业务的业务信息。S1201: The UE sends the service information of the currently ongoing service to the radio access network device.
如果UE与应用服务器之间通过无线接入网络设备建立数据连接并基于建立的数据连接进行数据传输,UE可以通过传输的数据包向无线接入网络设备发送当前正在使用业务的业务信息,例如,该业务信息可以为UE当前正在播放视频的缓存大小。If the UE establishes a data connection with the application server through the wireless access network device and performs data transmission based on the established data connection, the UE may send the service information of the currently used service to the wireless access network device by using the transmitted data packet, for example, The service information may be a buffer size of a video currently being played by the UE.
需要说明的是,步骤S121为可选步骤,具体实施时,也可以不执行步骤S121,直接执行步骤S122。It should be noted that step S121 is an optional step. In specific implementation, step S122 may be directly executed without executing step S121.
S1202、无线接入网络设备确定当前的无线网络环境信息。S1202: The wireless access network device determines current wireless network environment information.
具体实施时,无线接入网络设备可以根据接收到的业务信息确定当前的无线网络环境信息,例如,无线接入网络可以根据UE本地的缓存信息确定UE当前的可用带宽,具体地,如果UE本地的缓存小于预设阈值,则无线接入网络增大分配给UE的带宽,即增大UE的可用带宽。In a specific implementation, the radio access network device may determine the current radio network environment information according to the received service information. For example, the radio access network may determine the current available bandwidth of the UE according to the local cache information of the UE, specifically, if the UE is local. If the cache is smaller than the preset threshold, the radio access network increases the bandwidth allocated to the UE, that is, increases the available bandwidth of the UE.
在一些实施例中,无线接入网络设备还可以结合UE当前的信道质量或者小区拥塞信息确定UE的可用带宽。In some embodiments, the radio access network device may also determine the available bandwidth of the UE in conjunction with the current channel quality or cell congestion information of the UE.
如果不执行步骤S121,则无线接入网络设备可以直接根据UE当前的信道质量或者小区拥塞信息,例如,如果根据小区拥塞信息确定当前小区拥塞率低于预设阈值时,则无线接入网络增大分配给UE的带宽,即增大UE的可用带宽。If the step S121 is not performed, the radio access network device may directly according to the current channel quality of the UE or the cell congestion information. For example, if the current cell congestion rate is lower than a preset threshold according to the cell congestion information, the radio access network increases. The bandwidth allocated to the UE is increased, that is, the available bandwidth of the UE is increased.
S1203、无线接入网络设备向UE发送确定出的无线网络环境信息。S1203. The radio access network device sends the determined radio network environment information to the UE.
具体的,无线接入网络设备使用空口信令向UE发送无线网络环境信息;或者无线接入网络设备使用数据包向UE发送的无线网络环境信息。Specifically, the radio access network device sends the radio network environment information to the UE by using air interface signaling; or the radio network environment information that the radio access network device sends to the UE by using the data packet.
其中,所述数据包包括用户平面数据包,例如,MAC数据包或者RLC数据包。所述空口信令包括层1信令、层2信令或者层3信令,例如,层2 信令中的MAC CE信令,层3信令中的RRC信令。The data packet includes a user plane data packet, for example, a MAC data packet or an RLC data packet. The air interface signaling includes layer 1 signaling, layer 2 signaling or layer 3 signaling, for example, layer 2 MAC CE signaling in signaling, RRC signaling in layer 3 signaling.
S1204、UE根据接收到的无线网络环境信息确定数据传输控制信息。S1204. The UE determines data transmission control information according to the received wireless network environment information.
在获得了无线接入设备发送的无线网络环境信息后,UE根据接收到的无线网络环境信息确定自身与应用服务器之间的传输控制信息。以无线网络环境中的可用带宽信息为例,其中,UE的可用带宽可以根据UE信道环境,小区拥塞程度等信息来确定,如果可用带宽增大,则UE与应用服务器之间交互传输控制信息来增大数据包发送和接收窗口或者选择更高的数据发送和接收码率,如果可用带宽减小,则UE与应用服务器之间交互传输控制信息来减少数据包发送或接收窗口或者选择更低的数据发送和接收码率;或者根据RAN侧缓存大小和变化来调整发送或接收窗口或者接收码率,如果缓存低于某个门限左右(比如50%等),且缓存在减少,则UE与应用服务器之间交互传输控制信息来增加数据发送速率或者选择较高的数据接收码率,如果缓存高于某个门限左右(比如80%等),且缓存在增加,则UE与应用服务器之间交互传输控制信息来减少数据发送速率或者选择较低的数据接收码率;或者UE根据无线网络环境中的小区拥塞信息来调整接收或发送窗口大小或者数据接收码率等等,本发明实施例中不再一一列举。After obtaining the wireless network environment information sent by the wireless access device, the UE determines the transmission control information between itself and the application server according to the received wireless network environment information. Taking the available bandwidth information in the wireless network environment as an example, the available bandwidth of the UE may be determined according to information such as the UE channel environment and the degree of congestion of the cell. If the available bandwidth is increased, the UE and the application server exchange control information. Increase the packet transmission and reception window or select a higher data transmission and reception code rate. If the available bandwidth is reduced, the UE and the application server exchange control information to reduce the data packet transmission or reception window or select a lower one. Data transmission and reception code rate; or adjust the transmission or reception window or receiving code rate according to the RAN side buffer size and change. If the buffer is lower than a certain threshold (such as 50%, etc.), and the buffer is decreasing, the UE and the application The server exchanges control information to increase the data transmission rate or select a higher data reception rate. If the cache is higher than a certain threshold (such as 80%, etc.) and the cache is increasing, the UE interacts with the application server. Transmitting control information to reduce data transmission rate or selecting a lower data reception rate; or UE according to wireless network The cell congestion information in the environment is used to adjust the size of the receiving or sending window or the data receiving code rate, etc., which are not enumerated in the embodiment of the present invention.
S1204’、UE根据无线网络环境对自身与应用服务器之间的数据传输进行传输控制。S1204', the UE performs transmission control on data transmission between itself and the application server according to the wireless network environment.
其中,步骤S1204和步骤S1204’没有一定的先后执行顺序,两者可以同时执行,步骤S1204’也可以先于步骤S1204执行。The step S1204 and the step S1204' do not have a certain order of execution, and both can be performed simultaneously, and the step S1204' can also be performed before the step S1204.
S1205、将确定出的数据传输控制信息发送给应用服务器。S1205: Send the determined data transmission control information to the application server.
本步骤中,将步骤S122中确定出的数据传输控制信息发送给应用服务器,使得应用服务器根据UE侧确定出的数据传输控制信息调整自身的数据传输速率或者发送窗口。In this step, the data transmission control information determined in step S122 is sent to the application server, so that the application server adjusts its own data transmission rate or transmission window according to the data transmission control information determined by the UE side.
S1206、应用服务器根据接收到的数据传输控制信息对自身与UE之间 的数据传输进行传输控制。S1206. The application server controls the information between the UE and the UE according to the received data transmission control information. The data transmission is carried out for transmission control.
例如,视频服务器根据UE发送的数据接收码率,调整自身向UE发送视频数据的码率;又如,TCP服务器根据UE发送的接收窗口大小以及自身维护的拥塞窗口大小确定自身向UE发送TCP包的发送窗口大小等等。For example, the video server adjusts the code rate of the video data transmitted by the UE according to the data received by the UE. For example, the TCP server determines that the TCP packet is sent to the UE according to the size of the receiving window sent by the UE and the size of the congestion window maintained by the UE. The send window size and so on.
上述UE侧实施的信息传输方法中,由于UE根据无线接入网络设备发送的实时无线网络环境信息确定自身与应用服务器之间的数据传输控制信息并通知应用服务器进行相应调整,从而能够使得UE与应用服务器之间的数据传输控制能够随着无线网络环境的变化而调整,以使数据传输速率与实时的无线网络环境相匹配,从而提高了数据传输效率和网络资源利用率。In the information transmission method implemented by the UE side, the UE determines the data transmission control information between the UE and the application server according to the real-time wireless network environment information sent by the radio access network device, and notifies the application server to perform corresponding adjustment, thereby enabling the UE to The data transmission control between the application servers can be adjusted as the wireless network environment changes, so that the data transmission rate matches the real-time wireless network environment, thereby improving data transmission efficiency and network resource utilization.
