Detailed ways

The technical solutions in the embodiments of the present invention will be described below with reference to the drawings in the embodiments of the present invention.

In the embodiments of the present invention, words such as "exemplary" or "for example" are used as examples, illustrations or illustrations. Any embodiment or design solution described as "exemplary" or "for example" in the embodiments of the present invention shall not be construed as being more preferred or more advantageous than other embodiments or design solutions. Rather, the use of words such as "exemplary" or "such as" is intended to present related concepts in a concrete manner.

In the description of the present invention, unless otherwise specified, "/" means "or", for example, A/B may mean A or B. The "and/or" in this article is just an association relationship describing associated objects, which means that there can be three relationships, for example, A and/or B, which can mean: A exists alone, A and B exist at the same time, and B exists alone These three situations. In addition, "at least one" and "plurality" mean two or more. Words such as "first" and "second" do not limit the number and order of execution, and words such as "first" and "second" do not necessarily limit the difference.

The related technologies involved in the embodiments of the present invention will be described below.

In related technologies, data transmission between terminals is implemented by means of a packet forwarding network. For example, before the first terminal transmits data to the second terminal, the second terminal may send an MTU message to the first terminal, indicating the maximum size of the data service unit it can receive; For data, the data to be transmitted is divided into multiple data packets conforming to the MTU, and these data packets are sent to the second terminal through the network side. For example, when the MTU message indicates that the maximum size of the data service unit that the second terminal can receive is 1.5Kb, the first terminal can divide the data to be transmitted into multiple 1.5Kb data packets, and encapsulate and send these data packets to the network side , forwarded by the network side to the second terminal.

Based on the packet forwarding network, the second terminal needs to receive all data packets corresponding to the data to be transmitted before processing the data to be transmitted. Since the second terminal receives all the data packets corresponding to the data to be transmitted, its corresponding computing resource is in an idle state, which will reduce the utilization rate of the computing resource of the second terminal. On the other hand, when data to be transmitted corresponding to multiple services is transmitted between the first terminal and the second terminal, in order to avoid congestion of the transmission link, a congestion control algorithm is usually used to make the data packets corresponding to the data to be transmitted share the first The bandwidth of the transmission link between the terminal and the second terminal, which will further increase the transmission time of the data packet corresponding to the data to be transmitted, which will lead to an increase in the time when the computing resources of the second terminal are idle, and the utilization rate of computing resources is lower .

The method for determining resources provided by the embodiments of the present invention may be applicable to a communication system of a wireless network. Fig. 1 shows a schematic structural diagram of the communication system. As shown in FIG. 1 , a communication system 10 includes user equipment 101 and base station equipment 102 . Wherein, the user equipment 101 is connected to the base station equipment 102 .

The user equipment 101 may be a terminal device with a wireless transceiver function, such as a mobile phone, a tablet computer, a relay user equipment, and the like.

The base station device 102 may be a base station (gNode B, gNB) in 5G communication, or an evolved base station (evolutional eNodeB) in evolved LTE, or other devices with a relay function.

The user equipment 101 is configured to determine that there is an untransmitted fragmented data packet in the UE, and send a fragmentation indication to the base station device 102 .

Wherein, the segment indication is used to indicate the size of the untransmitted segmented data packet in the first to-be-transmitted data packet, and the identifier of the first to-be-transmitted data packet. The base station device 102 is configured to receive the segmentation indication sent by the user equipment 101, and determine the size of the second data packet to be transmitted according to the identifier of the first data packet to be transmitted; the base station device 102 is also configured to determine the size of the second data packet to be transmitted according to the The size and the size of the second data packet to be transmitted determine the target network resource allocated for the UE.

The base station device 102 is also configured to store various types of data packet indication information; wherein, the data packet indication information includes the identifier of the data packet, the content carried by the data packet, and the size of the data packet.

The user equipment 101 communicates with the base station equipment 102 through a network protocol stack. As shown in Figure 2, the network protocol stack includes a service data adaptation protocol (service data adaptation protocol, SDAP) layer, a packet data convergence protocol (packet data convergence protocol, PDCP) layer, a radio link control (radio link control structure, RLC) layer layer, medium access control (medium access control, MAC) layer and physical (physical, PHY) layer.

Among them, the PDCP layer communicates with the MAC layer through the logical channel of the RLC layer. The data received by the RLC layer from the PDCP layer or sent to the PDCP layer is called RLC SDU or PDCP PDU; the data received by the RLC layer from the MAC layer or sent to the MAC layer Layer data is called RLC PDU or MAC SDU. Here, a protocol data unit (protocol data unit, PDU) is used to indicate data transmission according to a related protocol, and a service data unit (service data unit, SDU) is used to bear the transmitted data.

The method for determining resources provided by the embodiments of the present invention will be specifically described below with reference to the accompanying drawings.

As shown in Figure 3, the resource determination method provided by the embodiment of the present invention includes the following S201-S205:

S201. The UE determines that there is an untransmitted segmented data packet in the UE.

As a possible implementation, when the UE is transmitting the first data packet to be transmitted, if the network resources allocated by the base station equipment cannot enable the UE to send the first data packet to be transmitted at one time, then the UE transmits the first data packet to be transmitted After the data packet is fragmented, it is determined that there is an untransmitted fragmented data packet in the UE.

It should be noted that the UE reports a buffer status report (buffer status reporting, BSR) to the base station device according to the network protocol, so as to indicate the amount of uplink data to be transmitted by the base station device. For example, the BSR reported by the UE indicates that the UE has 5000 bits of data packets to be transmitted.

Correspondingly, the base station device allocates network resources for the UE according to the BSR reported by the UE and the preset scheduling algorithm. In the case of relatively tight network resources, the network resources allocated by the base station equipment to the UE cannot satisfy the UE to send all data packets at one time. Therefore, the UE will generate some fragmented data packets during data transmission.

Wherein, the preset scheduling algorithm is pre-set in the base station equipment by operation and maintenance personnel.

Exemplarily, if the BSR indicates that the data packet to be transmitted is 5000 bits, but the network resource allocated by the base station device to the UE is 1000 bits. In this case, when the UE sends the data packet to be transmitted, it will divide the data packet to be transmitted into a data packet with a size of 1000 bits and a data packet with a size of 4000 bits. Further, the UE will transmit the 1000-bit data packet through the aforementioned network resources, and the 4000-bit data packet will be stored in the UE as an untransmitted segmented data packet.

S202. The UE generates a segmentation indication.

Wherein, the segmentation indication is used to indicate the remaining transmission information of the first data packet to be transmitted, and the identification of the first data packet to be transmitted; the first data packet to be transmitted is the data packet to be transmitted in which the segmented data packet is not transmitted; the remaining The transmission information is used to reflect the size of untransmitted segmented data packets in the first data packet to be transmitted.

As a possible implementation manner, after determining that there is an untransmitted segmented data packet in the UE, the UE acquires the size of the untransmitted segmented data packet and the identifier of the first to-be-transmitted data packet where the untransmitted segmented data packet is located. Further, the UE adds the identifier of the first data packet to be transmitted and the size of the untransmitted segmented data packet in the first data packet to be transmitted to a media access control (media access control, MAC)-control element (control element, CE) ) in the logical channel identification (logical channel identify, LCID) field to generate a segmentation indication.

As another possible implementation, the UE adds the identifier of the first data packet to be transmitted and the occupancy ratio of untransmitted segment data packets in the first data packet to be transmitted to the LCID field in the MAC-CE to generate a segment instruct.

It should be noted that the LCID field is located in the MAC-CE header; the MAC-CE header consists of four header fields R/R/E/LCID. The operation and maintenance personnel set the PN field and the PS field in the LCID field in advance. Wherein, the PN field is used to carry the identifier of the first data packet to be transmitted, and the PS field is used to carry remaining transmission information of the first data packet to be transmitted.

Exemplarily, when the remaining transmission information is the occupancy ratio of untransmitted segmented data packets in the first to-be-transmitted data packet, the value of the PN field is 20, indicating that no segmented data packets are transmitted in the first to-be-transmitted data packet The occupancy ratio is 20%.

As shown in Table 1, there are indication information of various types of data packets to be transmitted stored in the UE, and the information indication information includes the identifier of the data packet to be transmitted, the type of the data packet to be transmitted, and the size of the data packet. Table 1 specifies the corresponding sizes of data packets to be transmitted carrying various contents, for example, the size of a data packet to be transmitted carrying pictures is 800 bits. Table 1 exemplarily shows a data packet indication information reference, and the present invention does not limit the actual identification of the data packet and the actual size of different types of data packets to be transmitted.

Table 1

ID of the packet to be transmitted The type of packet to be transmitted The size of the packet to be transmitted 1 picture 800bit 2 video 1600bit 3 audio 1000bit … … … no letter 200bit

In practical applications, the UE may query the identifier of the first data packet to be transmitted and the size of the data packet to be transmitted from the above Table 1 according to the content carried in the first data packet to be transmitted.

For example, taking the type of the first data packet to be transmitted as a picture, the size of the untransmitted segmented data packet in the first data packet to be transmitted is 160 bits, and the remaining transmission information is the occupation ratio as an example, combined with Table 1, it is Table 1 When the picture data packet in , then the PN field corresponds to 0000 0001, reflecting the identification of the first data packet to be transmitted as 1; the PS field corresponds to 00010100, reflecting the proportion of untransmitted segmented data packets in the first data packet to be transmitted 20%.

S203. The UE sends a segmentation indication to the base station device.

As a possible implementation manner, after generating the segmentation indication, the UE sends the MAC-CE with the segmentation indication to the base station device.

As another possible implementation manner, the UE may also send the MAC-CE with the segmentation indication to the base station device according to a preset period.

It should be noted that the preset period is pre-set in the UE by the operation and maintenance personnel.

Correspondingly, the base station device receives the segmentation indication sent by the UE according to the foregoing network protocol.

S204. The base station device determines the size of the second data packet to be transmitted according to the identifier of the first data packet to be transmitted.

Wherein, the size of the second data packet to be transmitted is the same as that of the first data packet to be transmitted.

As a possible implementation manner, the base station device queries the size of the second data packet to be transmitted according to the identifier of the first data packet to be transmitted.

It should be noted that both the first data packet to be transmitted and the second data packet to be transmitted are data packets to be transmitted. The content carried by the second data packet to be transmitted may be the same as or different from the first data packet to be transmitted. Usually, the content carried by the second data packet to be transmitted is the same as that of the first data packet to be transmitted, because the UE has a higher probability of transmitting the same type of data packet within the same preset time. For example, the UE may need to transmit multiple pictures at a time, so the content carried in the second data packet to be transmitted is also a picture.

The base station device stores the same indication information of the data packet to be transmitted as that in the UE.

Exemplarily, as shown in Table 1, when the identifier of the first data packet to be transmitted is 1, the base station device may determine that the size of the second data packet is 800 bits.

S205. The base station device determines target network resources for allocation to the UE according to the size of the untransmitted segmented data packet and the size of the second to-be-transmitted data packet.

Wherein, the target network resource is used to carry untransmitted segmented data packets and at least one second to-be-transmitted data packet.

As a possible implementation manner, the base station device determines the number of at least one second data packet to be transmitted based on the maximum allocable network resource and the size of the untransmitted segmented data packet, and determines the size of the at least one second data packet to be transmitted . Further, the UE determines that the sum of the size of the at least one second to-be-transmitted data packet and the size of the untransmitted segmented data packet is the size of the target network resource.

For the specific implementation manner of this step, reference may be made to the subsequent description of the embodiment of the present invention, and details are not repeated here.

It can be understood that, after determining the size of the untransmitted segmented data packet and the size of the second to-be-transmitted data packet in the UE, the base station device may, according to the size of the untransmitted segmented data packet and the size of the second to-be-transmitted data packet, be The UE determines a target network resource capable of carrying the untransmitted segmented data packet and at least one second to-be-transmitted data packet; in this way, the determined network resource can be more suitable for the UE to transmit the non-segmented data packet.

In one design, in the case that the remaining transmission information is the occupation ratio of untransmitted segmented data packets in the first to-be-transmitted data packets, the following S301-S302 are further included after the above S203 provided by the embodiment of the present invention.

S301. The base station device determines the size of a first data packet to be transmitted.

As a possible implementation manner, the base station device queries the size of the first data packet to be transmitted according to the identifier of the first data packet to be transmitted.

S302. The base station device determines the size of the untransmitted segmented data packet according to the size of the first data packet to be transmitted and remaining transmission information.

As a possible implementation manner, the base station device determines that the product of the size of the first data packet to be transmitted and the occupation ratio is the size of the untransmitted segmented data packet.

For example, if the size of the first data packet to be transmitted is 800 bits and the occupation ratio is 20%, the size of the untransmitted segmented data packet is: 800 bits*20%=160 bits.

In one design, in order to determine the target network resource allocated to the UE, the above S205 provided by the embodiment of the present invention specifically includes the following S2051.

S2051. The base station device determines the target network resource from the maximum allocatable network resources allocated by the base station device to the UE according to the size of the untransmitted segmented data packet and the size of the second data packet to be transmitted.

Wherein, the difference between the maximum allocable network resource and the size of the untransmitted segmented data packet is an integer multiple of the size of the second data packet to be transmitted.

Exemplarily, the maximum allocatable network resource allocated by the base station device to the UE is 1000 bits, the size of untransmitted segmented data packets is 160 bits, the size of each second data packet to be transmitted is 800 bits, and the size of each second data packet to be transmitted is Count 2. Since 1000-160=840, the base station device determines that under the current network resources, the number of second data packets to be transmitted is allowed to be 1, and since the size of one second data packet to be transmitted is 800 bits, the base station device will Allocate 960bit network resources to UE. At this time, the data packet transmitted by the UE is: 160 bits of the untransmitted segmented data packet+800 bits of the second data packet to be transmitted=960 bits. In this way, in the subsequent transmission process, due to the limitation of network resources, fragmentation when the UE transmits data packets is avoided.

In one design, after the above S205 provided in the embodiment of the present invention, the following S401-S402 are also included.

S401. The UE determines the target network resource allocated by the base station device and the size of the second data packet to be transmitted.

Wherein, the size of the second data packet to be transmitted is the same as that of the first data packet to be transmitted.

After the base station device determines the target network resource allocated to the UE, the UE determines the target network resource allocated by the base station device and the size of the second data packet to be transmitted.

S402. The UE determines a target data packet corresponding to the target network resource according to the target network resource, the size of the second data packet to be transmitted, and the size of the untransmitted segmented data packet.

Exemplarily, if the target network resource is 960bit, the size of the untransmitted segmented data packet is 160bit, and the size of the second to-be-transmitted data packet is 800bit, then the untransmitted segmented data packet and one second to-be-transmitted data packet are determined for the target packet.

The technical solutions provided by the above embodiments bring at least the following beneficial effects: the base station device receives the segmentation indication sent by the user equipment UE; since the segmentation indication can indicate the remaining transmission information of the first data packet to be transmitted, and the first data packet to be transmitted identification; therefore, the base station device can obtain the size of the untransmitted segmented data packet in the first transmission data packet, and determine the size of the second data packet to be transmitted according to the identification of the first data packet to be transmitted; the second data packet to be transmitted The size of the packet is the same as that of the first data packet to be transmitted; after determining the size of the untransmitted segmented data packet in the UE and the size of the second to be transmitted data packet, the station device can further 2. The size of the data packet to be transmitted, determine the target network resource capable of carrying the untransmitted segmented data packet and at least one second data packet to be transmitted for the UE; in this way, the determined network resource can be more suitable for the UE regardless of Segment transmission data packets to adapt to the burst forwarding technology of future networks
