Therefore, how to reduce the number of freezes during video playback, so as to ensure the quality of user experience (Quality of Experience; abbreviation) : QoE) level is a very important issue faced by operators.

In the Long Term Evolution (Long Term Evolution; abbreviated as: LTE) system, when a user terminal (User Equipment; abbreviated as: UE) is playing a video, it can send QoE parameters to the server, including buffer status information, so that the server can follow The buffer status information better controls the video streaming media transmission to the UE to achieve a better experience. In the prior art, the UE may adopt the feedback mechanism in the video transmission mode based on the application layer hypertext transfer protocol (Hypertext transfer protocol; abbreviation: HTTP) protocol to send the buffer status information to the server, where the transmission mode includes HTTP-based dynamic adaptive streaming (Dynamic Adaptive Streaming over HTTP; abbreviated as: DASH) mode, HTTP-based progressive download (HTTP Progressive Download) mode, etc. The UE can also send buffer status information through Real Time Streaming Protocol (RTSP) or 3rd Generation Partnership Project Adaptation buffer (3rd Generation Partnership Project Adaptation buffer; abbreviation: 3GPP Adaptation buffer), etc. To the server. For the base station side, it is intercepted from the QoE parameters sent by the UE to the server by means of Deep Packet Inspection (DPI) to obtain buffer status information.

However, in the prior art, when the base station obtains the buffer status information by means of DPI, as the video transmission protocol based on when the UE sends the buffer status information to the server is different, the specific detection methods are also different. Therefore, It is more difficult for the base station to obtain the buffer status information, which results in a higher complexity of the system. To

Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

FIG. 1 is a schematic flowchart of Embodiment 1 of a method for processing buffer status information according to the present invention. The embodiment of the present invention provides a method for processing buffer status information. The method can be executed by any device that executes the method for processing buffer status information. The device can be various terminal devices with video playback functions, such as: Personal computers (personal computers; PCs for short), mobile phones, PADs, etc., can be specifically implemented by software and/or hardware. As shown in Figure 1, the method of this embodiment may include:

Step 101: The AP of the UE obtains buffer status information, and sends the buffer status information to the BP of the UE.

In this embodiment, those skilled in the art can understand that the application processor (Application Processor; AP for short) in the UE is generally responsible for running an operating system, such as common and more complex operating systems such as iOS, Android, or Windows Mobile. In addition, because the AP has powerful computing capabilities, it can also handle various multimedia applications, such as audio, video, and other multimedia-related functions. The digital baseband processor (Baseband Processor; abbreviated as: BP) is generally responsible for the transmission of call voice uplink and downlink and other wireless data services, such as the processing of General Packet Radio Service (General Packet Radio Service; abbreviated as: GPRS).

When the UE needs to play the video downloaded in real time from the wireless network, the AP obtains related video data from the application server. The video data includes buffer status information, and the buffer status information includes the time that the buffered content can be played. After the AP obtains the buffer status information, it sends the buffer status information to the BP. In the specific implementation process, an interface can be defined between the AP and the BP. After the AP obtains the buffer status information, the buffer status information is sent to the BP through this interface.

Step 102: The BP of the UE reports the MAC PDU signaling carrying buffer status information to the base station, so that the base station can allocate resources for the UE according to the buffer status information in the MAC PDU signaling. To

In this embodiment, after BP obtains the current buffer status information, it encapsulates the buffer status information in a medium access control (medium access control; MAC for short) protocol data unit (Protocol Data Unit; for short: PDU) signaling In, and reported to the MAC layer of the base station. Specifically, after BP encapsulates the buffer status information in the MAC PDU signaling, the MAC PDU signaling is multiplexed into the uplink synchronization channel (Uplink-Synchronization Channel; abbreviated as: UL-SCH), and then the UL-SCH The channel is remapped to the UL-SCH through the Physical Uplink Shared Channel (Physical Uplink Shared Channe; PUSCH), and the MAC PDU signaling is reported to the base station through the UL-SCH. In addition, the BP of the UE only reports the buffer status information to the base station, which avoids the problem of wasting bandwidth caused by reporting all QoE parameters to the base station in the prior art.

In the method for processing buffer status information provided by the embodiment of the present invention, the AP of the UE obtains the buffer status information and sends the buffer status information to the BP of the UE; the BP of the UE sends the MAC PDU message carrying the buffer status information The command is reported to the base station for the base station to allocate resources for the UE according to the buffer status information in the MAC PDU signaling. After the AP of the UE sends the buffer status information to the BP, the BP carries the buffer status information in the MAC PDU signaling and reports it to the base station, so that the base station obtains the buffer status information in a simpler way and reduces the complexity of the system. degree.

Optionally, in the method embodiment described above, the BP of the UE determines whether the buffer status information is less than a first preset threshold; if it is determined that the buffer status information is less than the first preset threshold, the BP will carry the buffer status The MAC PDU signaling of the information is reported to the base station.

Specifically, when the BP of the UE determines that the buffer status information is less than the first preset threshold, it means that the video being played in the UE is about to freeze. To avoid this, the BP will carry the MAC with the buffer status information. The PDU signaling is reported to the base station so that the base station allocates resources for the UE. Among them, the first preset threshold can be selected according to actual conditions, for example: 1000ms, 1500ms, etc. can be selected. The specific value of the first preset threshold is not particularly limited in the present invention.

In the method for processing buffer status information provided by the embodiment of the present invention, the AP of the UE obtains the buffer status information and sends the buffer status information to the BP of the UE; the BP of the UE sends the MAC PDU message carrying the buffer status information The command is reported to the base station for the base station to allocate resources for the UE according to the buffer status information in the MAC PDU signaling. After the AP of the UE sends the buffer status information to the BP, the BP carries the buffer status information in the MAC PDU signaling and reports it to the base station, so that the base station obtains the buffer status information in a simpler way and reduces the complexity of the system. degree. To In addition, when the BP determines that the buffer status information is less than the first preset threshold, the buffer status information is reported to the base station, which prevents the UE's video from freezing and improves the user's QoE level.

Optionally, in the method embodiment described above, the BP of the UE reports the MAC PDU signaling carrying buffer status information to the base station every preset time.

Specifically, the BP of the UE can report the MAC PDU signaling carrying buffer status information to the base station every preset time, where the preset time can be selected according to actual conditions, for example: 30ms, 50ms, etc. can be selected. For the specific value of the preset time, the present invention does not make a special limitation here.

In the method for processing buffer status information provided by the embodiment of the present invention, the AP of the UE obtains the buffer status information and sends the buffer status information to the BP of the UE; the BP of the UE sends the MAC PDU message carrying the buffer status information The command is reported to the base station for the base station to allocate resources for the UE according to the buffer status information in the MAC PDU signaling. After the AP of the UE sends the buffer status information to the BP, the BP carries the buffer status information in the MAC PDU signaling and reports it to the base station, so that the base station obtains the buffer status information in a simpler way and reduces the complexity of the system. degree. In addition, since the BP of the UE periodically reports buffer status information to the base station, bandwidth resources are saved.

Optionally, in the method embodiment described above, the MAC PDU signaling includes a MAC control unit and a sub-header field, the MAC control unit includes buffer status information, and the sub-header field includes a buffer status information identifier for identifying Buffer status information.

Specifically, those skilled in the art can understand that the MAC PDU signaling is composed of two parts: a MAC header field (MAC Header) and a MAC payload field (MAC Payload). Among them, the MAC payload field is composed of several MAC control elements (MAC control elements), MAC service data units (Service Data Unit; SDU for short), and padding parts. In this embodiment, a new MAC control unit can be inserted into the existing MAC PDU signaling, which includes the buffer status information, and its value is a binary value of the length of time that the content buffered in the UE’s buffer can be played. Indicates that in practical applications, the unit is generally 10 milliseconds. For example, when the content that has been cached in the buffer of the UE can continue to be played for 10 milliseconds, the value of the MAC control unit is 1.

In addition, the MAC header field is composed of several MAC sub-header fields, and each MAC sub-header field corresponds to the MAC control unit, To MAC SDU and the filled part. Those skilled in the art can understand that whether in the downlink SCH transmission channel or the uplink SCH transmission channel, the value of the logical channel ID (logical channel ID; abbreviation: LCID) in the MAC sub-header field is within the range of 01011-11000. It is reserved. Therefore, in this embodiment, one of the values reserved for LCID is selected as the identifier of the newly inserted MAC control unit, that is, the buffer status information identifier, which is used to correspond to the newly inserted MAC control unit. To identify the buffer status information. Figure 2 is a schematic diagram of the structure of the MAC sub-header field. As shown in Figure 2, the MAC sub-header field can have three formats, where R stands for reserved bits and its length is 1 bit; E stands for extended bits and its length is 1. bit; L corresponds to the length of the SDU or MAC control unit, in Byte, the length is 7bit or 15bit; F indicates the length of the L field, the length is 1bit or empty, if F is 0, the length of the L field is 7bit , If F is 1, the length of the L field is 15 bits. In practical applications, you can select a structure with a length of 7 bits in the L field, a structure with a length of 15 bits in the L field, or a structure with a fixed length in the L field according to the value of the newly added MAC control unit. Specifically, when the value of the buffer status information is lower Small, that is, when the value of the MAC control unit is small, the structure with the length of the L field of 7 bits can be selected, and when the value of the MAC control unit is large, the structure with the length of the L field of 15 bits can be selected.

In addition, due to the periodic reporting of the buffer status information, it will cause a large bandwidth consumption. In order to save bandwidth resources, according to the difference of the buffer status information, the length of the newly inserted MAC control unit can be defined as 1 byte or 2 bytes. Specifically, when the value of the buffer status information is less than the second preset threshold, the length of the MAC control unit is set to 1 byte to save bandwidth resources. When the value of the buffer status information is greater than or equal to the second preset When the threshold is set, the length of the MAC control unit can be set to 2 bytes to ensure that the buffer status information is completely sent. Since MAC control units of different lengths are defined according to different buffer status information, not only bandwidth can be saved to the utmost extent, but also the definition of MAC control units is more flexible. Wherein, the second preset threshold value can be set according to actual conditions, and the selection of the specific value of the second preset threshold value is not particularly limited in the present invention.

It should be noted that the first preset threshold is the reference value when the BP of the UE reports MAC PDU signaling to the base station, and the second preset threshold is the reference value when the length of the MAC control unit is defined. The value may be the same or different, and this embodiment is not particularly limited here.

In the method for processing buffer status information provided by the embodiment of the present invention, the AP of the UE obtains the buffer status information and sends the buffer status information to the BP of the UE; the BP of the UE will carry the buffer status information. To The MAC PDU signaling of the zone status information is reported to the base station for the base station to allocate resources for the UE according to the buffer status information in the MAC PDU signaling. After the AP of the UE sends the buffer status information to the BP, the BP carries the buffer status information in the MAC PDU signaling and reports it to the base station, so that the base station obtains the buffer status information in a simpler way and reduces the complexity of the system. degree. In addition, by carrying the buffer status information in the MAC PDU signaling and reporting it to the base station, the overhead of the MAC layer header can be saved.

FIG. 3 is a schematic flowchart of Embodiment 2 of a method for processing buffer status information of the present invention. The embodiment of the present invention provides a method for processing buffer status information. The method can be implemented by any device that executes the method for processing buffer status information. The device can be implemented by software and/or hardware. In this embodiment, the device can be integrated in the base station. As shown in FIG. 3, the method of this embodiment may include:

Step 301: The base station receives the MAC PDU signaling carrying buffer status information sent by the BP of the UE; wherein the buffer status information is the BP information obtained by the AP of the UE and sent to the UE.

In this embodiment, when the UE needs to play a video, the AP obtains related video data from the application server. The video data includes buffer status information, and the buffer status information includes the time that the buffered content can be played. After the AP obtains the buffer status information, it sends the buffer status information to the BP. In the specific implementation process, an interface can be defined between the AP and the BP. After the AP obtains the buffer status information, the buffer status information is sent to the BP through this interface. BP encapsulates the buffer status information in MAC PDU signaling and reports it to the MAC layer of the base station. In the specific implementation process, after BP encapsulates the buffer status information in the MAC PDU signaling, the MAC PDU signaling is multiplexed into the uplink synchronization channel UL-SCH, and then the UL-SCH channel is recreated through the PUSCH channel. Map to the UL-SCH channel, and report the MAC PDU signaling to the base station through the UL-SCH channel, so that the base station can obtain the buffer status information from the MAC PDU signaling, which avoids obtaining the buffer by DPI in the prior art The problem of user privacy leakage caused by status information.

Step 302: The base station allocates resources for the UE according to the buffer status information in the MAC PDU signaling.

In this embodiment, after the base station obtains the buffer status information from the MAC PDU signaling, it analyzes the buffer status information and allocates resources to the UE with less buffer status information, so as to minimize the video jam of the UE. The number of times, thereby improving the user’s QoE level. In practical applications, the base station can use the Proportional Fair (PF) algorithm to allocate resources to the UE. Specifically, in a specific resource scheduling period, when the base station receives the buffer status information reported by the UE, it will _{Update the r i, j} and in formula (1)

After the parameter update is completed, the base station first defines a scheduling priority on each resource block (Resource Block, abbreviated: RB) for each UE according to formula (1).

Where _mi,j represents the scheduling priority of the i-th UE on the j-th RB, and r _i,j represents the data rate that the i-th UE can achieve on the j-th RB;

Represents the average data rate of the i-th UE, and Buffer_Size represents buffer status information. According to formula (1), it can be concluded that in r _{i, j} and

When the value of Buffer_Size is fixed, the smaller the value of Buffer_Size _{, the larger the mi,j} , that is, the shorter the time that the content already stored in the UE’s buffer can continue to be played, the higher the priority of the UE to obtain RB High, therefore, will be allocated to resources preferentially.

After the base station calculates the scheduling priority of each UE on all RBs according to formula (1), it will allocate RBs to the UEs in the order of scheduling priority from high to low until the RBs are allocated. At this time, the resource scheduling period ends. The base station enters the next transmission time interval (Transmission Time Interval, TTI for short), and allocates resources to the UE in the same manner. It can be seen that using the combination of PF algorithm and buffer status information to allocate resources for UEs can not only ensure fairness and greater throughput, but also can allocate resources preferentially to UEs with less buffer status information, reducing The number of times the UE is stuck, thereby ensuring the QoE of the UE.

In the method for processing buffer status information provided by the embodiment of the present invention, the base station receives MAC PDU signaling carrying buffer status information sent by the BP of the UE; wherein the buffer status information is obtained by the AP of the UE and sent to The BP information of the UE; the base station allocates resources for the UE according to the buffer status information in the MAC PDU signaling. After the AP of the UE sends the buffer status information to the BP, the BP carries the buffer status information in the MAC PDU signaling and reports it to the base station, so that the base station obtains the buffer status information in a simpler way and reduces the complexity of the system. degree.
