In a communication system, QCI (QoS Class Identifier) corresponding to each service is defined in 3GPP (3rd Generation Partnership Project), for example, voice call service corresponds to QCI1, and HTTP (hypertext Transfer Protocol) service corresponds to QCI 9. Wherein, QCI1-4 is a GBR (Guaranteed Bit Rate) bearer, and QCI5-9 is a Non-GBR bearer; for a DRB (Data Radio Bearer ) of the GBR, a lower limit of rate guarantee and an upper limit of rate guarantee are respectively defined; while the DRB for Non-GBR defines the upper limit of the rate guarantee at the UE level, the protocol does not define the lower limit of the DRB rate guarantee for Non-GBR because the traffic of Non-GBR is best effort traffic. However, to guarantee the user-perceived experience, the operator will typically define the Minimum guaranteed Rate of the DRB of Non-GBR, i.e. the MinBR (Minimum Bit Rate).
Among them, a DRB of a Non-GBR can carry multiple types of services, such as a File Transfer Protocol (FTP) download type service, an HTTP flow web page type service, and an online video service. The demands of different service types on the MinBR are different, for example, for HTTP type service, the rate of 128kbps can be basically met, and for online video service, the rate of 1.5Mbps can be basically met; a smaller fixed value, such as 64kbps, is usually configured for the MinBR of the DRB to guarantee the GBR-supported service when there are more cell users; therefore, when the DRB carries the video service, the problems of increased first broadcast delay, too long buffering time, many video blocking times, and the like are often caused.

Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.
One of the core ideas of the embodiment of the present invention is to distinguish the service types carried on the DRB, and when it is determined that the service carried on the DRB is a video service, determine a bit rate according to the definition of the video service, where the bit rate is greater than the basic bit rate and is a lower limit of a rate for guaranteeing the DRB carrying service; and in the process that the DRB bears the video service, the bit rate corresponding to the video definition is used as the MinBR of the DRB, so that the transmission rate of video data corresponding to the video service is improved by means of increasing the MinBR of the DRB, and the fluency of the video is ensured.
In the embodiment of the invention, when the user needs to carry out the service, the corresponding DRB can be established between the user and the base station, and the service data corresponding to the service is transmitted through the DRB so as to bear the service. In the embodiment of the invention, the service is corresponding to the QCIs, and each QCI has the corresponding guaranteed lower rate limit, so that the lower rate limit for guaranteeing the DRB to bear the service is determined after the DRB is established, wherein the lower rate limit for guaranteeing the DRB to bear the service can be called as the basic bit rate. For example, when browsing a web page, a user needs to establish an HTTP type service with a base station, and therefore needs to establish a DRB to carry the HTTP type service, where QCI of the HTTP type service is QCI9, and a lower limit of a DRB rate for guaranteeing the HTTP type service may be the lower limit of a DRB rate for guaranteeing Non-GBR.
Referring to fig. 1, a flowchart illustrating steps of an embodiment of a data processing method according to the present invention is shown, which may specifically include the following steps:
The data processing method provided by the embodiment of the invention is applied to a base station; after a DRB is established between a user and a base station, a corresponding service can be carried, and since the type of the carrying service corresponding to the same DRB includes a plurality of types, such as an FTP download type service, an HTTP type service, and a video type service, before the DRB carries a certain service, it is determined whether the carried service is a video service, if so, step 102 is executed, that is, the value of MinBR of the DRB is adjusted; if not, go to step 105. The DRB in the embodiment of the present invention refers to a DRB capable of carrying video services, and optionally, the DRB may be a DRB of Non-GBR; the Video service is a novel communication service in which a terminal provides Video content to a user through a mobile network, and the Video content includes Video image (Video) and Audio (Audio) information.
And 102, determining the definition corresponding to the video service.
And 103, determining a first bit rate according to the definition.
With the continuous development of video technology, in order to meet the requirements of users on video definition and improve user experience, the video definition is continuously improved, gradually improved from 480P to 720P and then to 1080P, and certainly, the video can be developed with higher definition; 480P is a display format that achieves a resolution of 720 × 480 in a progressive scan, and accordingly, a resolution of 720P is 1280 × 720, and a resolution of 1080P is 1920 × 1080. In the embodiment of the invention, the requirement of the video with higher definition on the transmission rate of the video data is higher, for example, when the transmission rate is 1.5Mbps, the smooth playing of the 720P video can be basically ensured, and when the transmission rate is 6Mbps, the smooth playing of the 1080P video can be basically ensured; in order to ensure the fluency of users for playing videos with various definitions and avoid resource waste, when the service borne by the DRB is determined to be a video service, the definition corresponding to the borne video service can be determined, and then a first bit rate is determined according to the definition of the video service; the first bit rate is the transmission rate of the downlink video service from the base station to the user terminal, and is greater than the basic bit rate, so as to ensure the fluency of the video played by the user terminal.
And step 104, taking the first bit rate as the minimum bit rate MinBR of the DRB in the process of carrying the video service by the DRB.
And after determining a first bit rate, taking the first bit rate as a MinBR of the DRB in the process of carrying the video service by the DRB.
And 105, taking the basic bit rate as the rate MinBR of the DRB.
When the service carried by the DRB is determined not to be the video service, because the transmission rates required by other services except the video service in the service carried by the Non-GBR are relatively low, the MinBR of the DRB does not need to be increased, and the basic bit rate can be used as the MinBR of the DRB.
In an example of the present invention, if the DRB base bit rate of the Non-GBR is 64kbps, and a user needs to perform an HTTP service, after the DRB is established, the DRB may be used to carry the bearer HTTP service; before the DRB bears the HTTP service, the base station judges that the service borne by the DRB is not the video service, and the MinBR value of the DRB is 64kbps in the process that the DRB bears the HTTP service; after the HTTP service is finished, when the DRB is used to carry the video service, if the determined first bit rate is 2Mbps, the MinBR value of the DRB is 2Mbps during the DRB carrying the video service.
To sum up, the embodiment of the present invention determines the type of the service carried on the DRB, and determines whether the carried service is a video service; if the carried service is determined to be a video service, determining definition corresponding to the video service, then determining a first bit rate according to the definition, and further taking the first bit rate as a minimum bit rate MinBR of the DRB in the process of carrying the video service by the DRB; wherein the first bit rate is greater than a basic bit rate, and the basic bit rate is a lower rate limit for guaranteeing the DRB bearer service; therefore, the embodiment of the invention increases the MinBR in the process of carrying the video service by the DRB, improves the data transmission rate corresponding to the video service, further reduces the video buffering time, reduces the video blocking times, ensures the video smoothness and improves the user experience.
In another embodiment of the present invention, if the number of video users simultaneously online in the same cell is large, in order to guarantee the services of other users, the value of the MinBR of the DRB may be adjusted according to the network resource usage of the cell during the process that the DRB carries the video services.
Referring to fig. 2, a flowchart illustrating steps of another embodiment of a data processing method according to the present invention is shown, which may specifically include the following steps:
In the embodiment of the invention, when the user acquires the service resource data, a Transmission Control Protocol (TCP) handshake message can be sent to the base station through the TCP, and after the terminal of the user successfully handshakes with the base station, the base station can send corresponding data to the user through the DRB. Specifically, a terminal of a user sends a link request to a base station, the base station sends a response message for granting the link to the terminal after receiving the link request, and then the terminal sends a message for determining the link to the base station again, so that the handshake between the two parties is successful; wherein, the TCP handshake message includes service type information. Before the data radio bears the DRB bearing service, the base station can obtain the service type information from the received TCP handshake message, and then judge whether the borne service is a video service according to the service type information; for example, if the service type information is video, it may be determined that the carried service is a video service. If the service carried by the DRB is a video service, then step 202 is executed; if the service carried by the DRB is not a video service, such as an HTTP service, step 208 is executed.
And 203, determining the definition corresponding to the video service.
And 204, searching the bit rate corresponding to the definition, and determining the bit rate corresponding to the definition as the first bit rate.
In the embodiment of the present invention, the TCP handshake message may further include resolution display format information, and since the resolution display formats corresponding to different resolutions are different, the base station may determine the resolution corresponding to the video service according to the resolution display format information. The definition may include 480P, 720P, and 1080P, and certainly, the definition may also include definitions of other resolution display formats as the video technology and the network technology are continuously developed, and the embodiment of the present invention does not limit the type of the definition. In the embodiment of the invention, the corresponding bit rates can be preset for various different definitions, for example, the bit rate corresponding to the 720P video is 1.5Mbps, and the bit rate corresponding to the 1080P video is 6 Mbps; the method can be specifically set according to requirements; and after the definition corresponding to the video service is determined, the bit rate corresponding to the definition can be searched, and then the bit rate corresponding to the situation degree is determined as the first bit rate.
The first bit rate may be taken as a MinBR of the DRB after the DRB starts carrying the video traffic. In this embodiment of the present invention, the first bit rate may be used as a MinBR of the DRB in a time period from when the DRB starts to carry the video service to when the DRB finishes carrying the video service; or within a preset time after the DRB starts to carry the video service, the first bit rate may be used as the MinBR of the DRB, and after a preset condition is met, the MinBR of the DRB is adjusted according to the method in step 206 and step 207; wherein the preset conditions may include: the playing time is greater than the preset time, and the buffer storage amount is greater than the buffer threshold value; the preset time can be set according to the requirement, such as 3 seconds, and the buffer threshold can also be set according to the requirement, such as 10%. In the embodiment of the invention, the former mode is suitable for the condition that the number of users in the cell is small at the same time, so that the whole process of video playing is ensured to be smooth; the latter mode is suitable for the situation that the number of users in the community is large at the same time, the video first playing is not delayed, the video is smooth when playing is started, and the waiting time of the users is saved. Wherein, in the process of the DRB carrying the video service, the adjustment of the MinBR mode of the DRB after meeting a preset condition is specifically as follows:
And step 207, using the second bit rate as the MinBR of the DRB.
In the embodiment of the present invention, in the process of carrying the video service by the DRB, the MinBR of the DRB is mainly adjusted according to the network performance of the cell where the user is located, that is, a second bit rate is determined according to the network performance and the basic bit rate of the cell where the user is located, and then the second bit rate is used as the MinBR of the DRB. In the embodiment of the invention, the average throughput of the cell and the maximum percentage of resources for supporting the video service are two important parameters for measuring the network performance of the cell; therefore, the reference bit rate can be calculated according to the average throughput, the maximum percentage of resources and the number of users currently performing the video service at the same time, and then the reference bit rate and the basic bit rate are compared, and the maximum value of the reference bit rate and the basic bit rate is used as the second bit rate. And then, according to the service of other users in the guaranteed cell, the minimum MinBR of the DRB of the user can be ensured not to be lower than the basic bit rate.
Alternatively, the reference bit rate may be calculated according to the following formula, specifically as follows:
wherein, the BR2Is a reference bit rate, KcellBit average throughput, P% maximum percentage, BRQCIBased on the bit rate, N is the number of users currently carrying out video service at the same time; kcellIs obtained by a smooth calculation of the throughput of the cell over a period of time.
And step 208, taking the basic bit rate as the rate MinBR of the DRB.
And when the service carried by the DRB is determined not to be the video service, taking the basic bit rate as the MinBR of the DRB.
In the embodiment of the invention, in the process of bearing the video service by the DRB, a first bit rate is taken as the MinBR of the DRB, when a preset condition is met, a second bit rate is taken as the MinBR of the DRB, and the second bit rate is determined according to the network performance of a cell, so that the first playing of the video is not delayed, the fluency when the video starts to play is ensured, and the waiting time of a user is saved; and the service of other users in the cell can be ensured.
