Description

Method and device for sending data in radio bearer

technical field

The present invention relates to the field of communications, in particular to a method and device for transmitting data in a radio bearer

Background technique

According to the current implementation plan, when RB (Radio Bearer, radio bearer) sends business data, it strictly follows the principle of first-come first-served processing; that is, after RB receives high-level business data, it does not perform any differentiated processing on the business data, and directly sends The service data units of the service data are stored in the data sending queue, and when the RB sends the high-level service data, the service data units in the queue are sent sequentially according to first-in-first-out.

However, in fact, the high-level business data received by the RB has very different requirements for the application layer QoS (Quality of Service, Quality of Service). Some services require as little delay as possible, while others require as much throughput as possible. For services that require as much throughput as possible, in order to achieve the maximum possible throughput, this part of the service will submit a large amount of service data to the RB to ensure the utilization of the air interface. This means that when RB receives this type of service, the amount of data it caches for this service will be large, and the time to send this service data is relatively long. According to the current first-come-first-served principle of RB processing services, all services after this service Data units are subject to a large cache latency.

In the process of realizing the above-mentioned RB internal data transmission, in scenarios where the air interface is limited such as cell congestion, the data of delay-sensitive services will be affected by services that are not delay-sensitive to large traffic, and the transmission delay will deteriorate sharply, making customer experience worse .

Detailed ways

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

An embodiment of the present invention provides a method for transmitting data in a radio bearer. The radio bearer RB (Radio Bearer) may be provided by Layer 2 for communication between UE and UTRAN (UMTS Terrestrial Radio Access Network, UMTS Terrestrial Radio Access Network) ), where the UTRAN is composed of a group of radio network subsystems (RNS, RadioNetwork Subsystem) connected to the core network through the Iu interface. An RNS consists of a radio network controller (Radio Network Controller, RNC) and one or more base stations. The base station is connected to the RNC through the Iub interface; as shown in Figure 1, including:

101. When receiving service data, the RNC (Radio Network Controller, radio network controller) determines the delay-sensitive priority of the service data. In this embodiment of the present invention, at least two delay-sensitive priorities may be set, for example, a high delay-sensitive priority and a low delay-sensitive priority. For business data with high latency requirements, its latency sensitive priority can be set to high latency sensitive priority.

For example, the determining the delay-sensitive priority of the service data may include: obtaining the delay-sensitive type of the service data; Delay-sensitive priority correspondence, determine the delay-sensitive priority of the service data. Wherein, corresponding to at least two delay-sensitive priorities set in the embodiment of the present invention, the delay-sensitive types of service data should include at least two different types, so as to distinguish the delay-sensitive priorities of service data.

102. The RNC rearranges Service Data Units (SDUs, Service Data Units) of the service data according to a scheduling policy, and the scheduling policy can be set at least according to the delay-sensitive priority of the service data.

For example, the RNC may rearrange the service data units of the service data according to the scheduling strategy, and the RNC may rearrange the service data units of the service data according to the delay sensitive priority of the service data; The service data unit of the received service data is first stored in the priority buffer queue, and then called out and sent when it is to be sent, the RNC can also be based on the time-delay sensitive priority of the service data or according to the time-delay sensitive priority of the service data The service data units of the service data are rearranged according to the delay-sensitive priority and the amount of transmittable data in the cache queue; the scheduling policy may include a scheduling algorithm and scheduling parameters used by each algorithm. The scheduling algorithm can adopt PQ (Priority Queue, priority queue), RR (Round Robin, round-robin scheduling) or WRR (Weighted Round Robin, weighted round-robin scheduling) scheduling algorithm. in:

PQ is a priority queue that can implement the data sending queue as a priority insertion mechanism. The data sending queue can determine the insertion position of the SDU according to the status of the buffered data priority in the queue and the priority of the received service data SDU, and the insertion position is after the same priority, and the lower priority Before; and inserting the SDU into the data sending queue. The scheduling parameter used in the scheduling algorithm may be a delay-sensitive priority number, which is user-configurable and includes at least two different delay-sensitive priority numbers.

RR is a scheduling algorithm that can implement SDU scheduling of service data in multiple priority buffer queues. After receiving the SDU of service data, the radio network controller does not directly insert it into the data sending queue, but first puts the SDU into the priority buffer queue corresponding to the corresponding delay-sensitive priority. When sending data , and then according to the order of the delay-sensitive priorities of the SDUs from high to low, obtain the SDUs from each priority buffer queue, and send them. The scheduling parameter used in the algorithm may be a delay-sensitive priority number, which is user-configurable, includes at least two different delay-sensitive priority numbers, and is related to the The number of priority buffer queues corresponding to the delay-sensitive priority is also user-configurable.

WRR is a scheduling algorithm improved on the basis of RR, which can set a scheduling ratio factor for each priority cache queue. Within a certain scheduling period, the service data that can be sent is allocated to each priority buffer queue according to the scheduling proportional coefficient, and the service data allocated according to the scheduling proportional coefficient is the current sendable data amount of each priority buffer queue. When sending data, according to the priority of priority or the scheduling tendency of sending business data volume priority, data is taken from each priority buffer queue and sent. The priority priority here means that as long as the amount of data that can be sent with a higher priority is greater than 0, data will be fetched from the higher priority cache queue; but the priority of sending data means that the priority with the largest amount of data that can be sent every time Data is fetched from the buffer queues. When the amount of data that can be sent in each buffer queue is equal, the data is preferentially fetched from the buffer queue with higher priority. When the current amount of data that can be sent in all priority buffer queues is less than or equal to 0, enter the next round of scheduling cycle and re-allocate the amount of data that can be sent. The scheduling parameters used in this algorithm, such as the number of priority levels, the scheduling ratio coefficient and the corresponding priority priority or the priority of the amount of data that can be sent, are all configurable by the user. The number of priority levels includes at least two different Latency sensitive priority number.

In the process of implementing the embodiments of the present invention, which scheduling algorithm to use and how to set the scheduling parameters corresponding to the scheduling algorithm used can be selected by the user according to specific needs; When the amount of data is small, for example, the delay-sensitive priority of web browsing is high-delay-sensitive priority, but when the user occasionally browses the web, the scheduling strategy of PQ or RR scheduling algorithm can be used; when the user knows the delay When the amount of service data with high sensitive priority is large, such as the delay sensitive priority of online video is high delay sensitive priority, and users often perform online video services, the scheduling strategy of the WRR scheduling algorithm can be used. However, the embodiment of the present invention does not limit this, and the user can make a specific selection according to the delay sensitivity priority of different services and different specific applications when implementing the embodiment of the present invention.

103. The RNC sends the rearranged service data unit.

In the embodiment of the present invention, after the RNC receives the service data in the radio bearer, it first determines the delay-sensitive priority of the service data, and then according to the scheduling policy set according to the delay-sensitive priority of the service data, the The service data units of the above-mentioned service data are rearranged and sent, so that the service data units of the service data with high delay sensitivity priority are sent first, thereby reducing the transmission delay of service data with high delay sensitivity and improving user experience.

Another embodiment of the present invention provides a method for sending data in a radio bearer. After the RNC receives the service data, in the process of rearranging and sending the SDUs of the service data according to the scheduling strategy, the RNC can directly rearrange the SDUs according to the scheduling strategy and put them into the In the data sending queue, send the arranged SDUs when sending service data; or temporarily store the SDUs in the buffer queue corresponding to the delay-sensitive priority according to the delay-sensitive priority, and then send the service data , the SDUs in each buffer queue are scheduled to be put into the data sending queue and sent according to the scheduling policy, which is not limited in the embodiment of the present invention. In the embodiment of the present invention, the SDU of the received service data is temporarily stored, and then the SDU is scheduled and sent when the service data is sent as an example, and the method for sending data in the radio bearer is specifically described, as shown in FIG. 2 , the method includes :

201. When the service data is transmitted in the RB, the RNC receives the service data. The service data may be data sent by an upper layer of the data link layer, and the upper layer may be the network layer or above.

202. When the RNC receives the service data, it judges whether the service data contains the delay-sensitive type of the service data; if it determines that the service data contains the delay-sensitive type, execute step 203; If it is determined that the service data does not include the delay-sensitive type, step 204 is performed.

Wherein, the delay-sensitive type of the service data can be obtained by GGSN (Gateway GPRS SupportNode, gateway GPRS support node) in the following manner, for example, the protocol header and message content of the service data message are carried out internally Identify, identify the protocol type of the business data, and obtain the QoS (Quality of Service, quality of service) grade of the business data application layer according to the protocol type of the business data, according to the QoS grade of the business data application layer acquired, and The corresponding relationship between the QoS level of the service data application layer and the delay-sensitive type of the service data, determine the delay-sensitive type of the service data, and carry the delay-sensitive type in the service data, so in the After receiving the service data, the RNC needs to perform corresponding operations according to whether the service data contains the delay-sensitive type of the service data.

203. The RNC directly receives the delay-sensitive type carried in the service data, and performs step 205.

204. The RNC identifies the received service data to obtain the delay-sensitive type of the service data, and executes step 205.

For example, the identifying the received service data to obtain the delay-sensitive type may include: analyzing the received service data to obtain the protocol type of the service data; obtaining the protocol type according to the obtained protocol type The QoS level of the application layer of the service data; according to the obtained QoS level of the application layer, and the corresponding relationship between the QoS level of the application layer of the service data and the delay sensitive type of the service data, determine the delay sensitivity of the service data type. In the process of implementing the embodiments of the present invention, the delay-sensitive type of service data can be specifically set by the user according to requirements, and the corresponding relationship between the delay-sensitive type and the QoS level of the service data application layer is saved; When the delay-sensitive type of service data, according to the QoS level of the application layer of the service data, and the corresponding relationship between the QoS level of the application layer of the service data and the delay-sensitive type, the delay-sensitive type.

205. The RNC determines the delay-sensitive priority of the service data according to the acquired delay-sensitive type and the corresponding relationship between the delay-sensitive type and the service delay-sensitive priority.

For example, when implementing the embodiment of the present invention, the user can set different delay-sensitive priorities for services of different delay-sensitive types, and save the corresponding relationship between the delay-sensitive types and the delay-sensitive priorities; when the RNC After the delay-sensitive type of the service data is acquired, the delay-sensitive priority of the service data is determined according to the pre-stored corresponding relationship, so as to rearrange the SDUs of the service data according to the scheduling policy. Wherein, the delay-sensitive priority may include setting at least two delay-sensitive priorities, so as to distinguish SUDs of service data with different delay-sensitive priorities.

206. The RNC puts the SDU of the service data into the buffer queue corresponding to the delay-sensitive priority according to the delay-sensitive priority of the service data.

Wherein, since the embodiments of the present invention divide the received service data into delay-sensitive priorities, corresponding buffer queues corresponding to the delay-sensitive priorities are set in the RNC, so as to prioritize different delay-sensitive The SDUs of service data at the different levels are put into different cache queues.

The embodiment of the present invention takes setting three delay-sensitive priorities and correspondingly setting three buffer queues corresponding to the delay-sensitive priorities as an example, and specifically explains how to store the SDUs of the service data according to the delay-sensitive priorities. The scheme of entering the cache queue corresponding to the delay-sensitive priority, as shown in Figure 3, after the delay-sensitive priority is determined for the received service data, if the delay-sensitive priority of the received service data is When the priority is high, put the SDU of the service data into the buffer queue corresponding to the high priority; if the delay-sensitive priority of the received service data is medium priority, put the SDU of the service data into the medium priority In the cache queue corresponding to the service level; if the delay-sensitive priority of the received service data is low priority, put the SDU of the service data into the cache queue corresponding to the low priority.

207. Schedule the SDUs in the buffer queue corresponding to different delay-sensitive priorities according to the scheduling policy, and rearrange the scheduled SDUs. The scheduling policy may be set at least according to the delay-sensitive priorities of service data.

For example, the scheduling of the SDUs in the cache queue corresponding to different delay-sensitive priorities according to the scheduling policy, and rearranging the scheduled SDUs may be based on the delay-sensitive priority of the service data or according to the The time-delay sensitive priority of business data and the amount of data that can be sent in the buffer queue, scheduling the service data units corresponding to different time-delay sensitive priorities in the buffer queue, and rearranging the scheduled service data units; the scheduling strategy It may include scheduling algorithms and scheduling parameters used by each algorithm. The scheduling algorithm can adopt RR (Round Robin, round-robin scheduling) or WRR (Weighted Round Robin, weighted round-robin scheduling) scheduling algorithm. in:

RR is a scheduling algorithm that can implement SDU scheduling of service data in multiple priority buffer queues. After receiving the SDU of service data, the radio network controller does not directly insert it into the data sending queue, but first puts the SDU into the priority buffer queue corresponding to the corresponding delay-sensitive priority. When sending data , and then according to the order of the delay-sensitive priorities of the SDUs from high to low, obtain the SDUs from each priority buffer queue, and send them. The scheduling parameter used in the algorithm may be a delay-sensitive priority number, which is user-configurable, includes at least two different delay-sensitive priority numbers, and is related to the The number of priority buffer queues corresponding to the delay-sensitive priority is also user-configurable.

WRR is a scheduling algorithm improved on the basis of RR, which can set a scheduling ratio factor for each priority cache queue. Within a certain scheduling period, the service data that can be sent is allocated to each priority buffer queue according to the scheduling proportional coefficient, and the service data allocated according to the scheduling proportional coefficient is the current sendable data amount of each priority buffer queue. When sending data, according to the priority of priority or the scheduling tendency of sending business data volume priority, data is taken from each priority buffer queue and sent. The priority priority here means that as long as the amount of data that can be sent with a higher priority is greater than 0, data will be fetched from the higher priority cache queue; but the priority of sending data means that the priority with the largest amount of data that can be sent every time Data is fetched from the buffer queues. When the amount of data that can be sent in each buffer queue is equal, the data is preferentially fetched from the buffer queue with higher priority. When the current amount of data that can be sent in all priority buffer queues is less than or equal to 0, enter the next round of scheduling cycle and re-allocate the amount of data that can be sent. The scheduling parameters used in this algorithm, such as the number of priority levels, the scheduling ratio coefficient and the corresponding priority priority or the priority of the amount of data that can be sent, are all configurable by the user. The number of priority levels includes at least two different Latency sensitive priority number.

In the process of implementing the embodiments of the present invention, which scheduling algorithm to use and how to set the scheduling parameters corresponding to the scheduling algorithm used can be selected by the user according to specific needs; When the amount of data is small, for example, the delay-sensitive priority of browsing the webpage is high-delay-sensitive priority, but when the user occasionally browses the webpage, the scheduling strategy of the RR scheduling algorithm can be used; when the user knows that the delay-sensitive priority When the amount of high-level service data is large, such as the delay-sensitive priority of online video is high delay-sensitive priority, and users often perform online video services, the scheduling strategy of the WRR scheduling algorithm can be used. However, the embodiment of the present invention does not limit this, and the user can make a specific selection according to the delay sensitivity priority of different services and different specific applications when implementing the embodiment of the present invention.

The scheduling parameter used in the scheduling algorithm may be a delay-sensitive priority number, which is user-configurable and includes at least two different delay-sensitive priority numbers.

RR is a scheduling algorithm that can implement SDU scheduling of service data in multiple priority buffer queues. After receiving the SDU of service data, the radio network controller does not directly insert it into the data sending queue, but first puts the SDU into the priority buffer queue corresponding to the corresponding delay-sensitive priority. When sending data , and then according to the order of the delay-sensitive priorities of the SDUs from high to low, obtain the SDUs from each priority buffer queue, and send them. The scheduling parameter used in the algorithm may be a delay-sensitive priority number, which is user-configurable, includes at least two different delay-sensitive priority numbers, and is related to the The number of priority buffer queues corresponding to the delay-sensitive priority is also user-configurable.
