Detailed Description
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 to mean serving as examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "e.g.," an embodiment of the present invention is not necessarily to be construed as preferred or advantageous over other embodiments or designs. Rather, use of the word "exemplary" or "such as" is intended to present concepts related in a concrete fashion.
In the description of the present invention, "/" means "or" unless otherwise specified, for example, a/B may mean a or B. "and/or" herein is merely an association describing an associated object, and means that there may be three relationships, e.g., a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone. Further, "at least one" or "a plurality" means two or more. The terms "first", "second", and the like do not necessarily limit the number and execution order, and the terms "first", "second", and the like do not necessarily limit the difference.
The following describes a related art to which embodiments of the present invention relate.
In the related art, 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 data service units it is capable of receiving; when the first terminal sends data to the second terminal through the network side, the data to be transmitted is divided into a plurality of data packets which accord with MTU, and the data packets are sent to the second terminal through the network side. If the MTU message indicates that the maximum size of the data service unit that can be received by the second terminal is 1.5Kb, the first terminal may divide the data to be transmitted into a plurality of data packets of 1.5Kb, and send the data packets to the network side, where the data packets are forwarded to the second terminal.
Based on the packet forwarding network, after the second terminal needs to receive the data packets corresponding to all the data to be transmitted, the second terminal can process the data to be transmitted. Since the corresponding computing resources are in an idle state in the process of receiving the data packets corresponding to all the data to be transmitted by the second terminal, the utilization rate of the computing resources of the second terminal is low. On the other hand, when data to be transmitted corresponding to a plurality of 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 enable the data packets corresponding to the data to be transmitted to share the bandwidth of the transmission link between the first terminal and the second terminal, which will further increase the transmission time of the data packets corresponding to the data to be transmitted, thereby causing an increase in the time that the computing resources of the second terminal are in an idle state, and the utilization rate of the computing resources is lower.
The resource determining method provided by the embodiment of the invention can be suitable for a communication system of a wireless network. Fig. 1 shows a schematic structural diagram of the communication system. As shown in fig. 1, the communication system 10 includes a user equipment 101 and a base station apparatus 102. Wherein the user equipment 101 is connected with the base station equipment 102.
The user equipment 101 may be a terminal device with wireless transceiving function, such as a mobile phone, a tablet computer, a relay user equipment, etc.
The base station device 102 may be a base station (enode B, gNB) in 5G communication, an evolved node B (evolved eNodeB) in evolved LTE, or other devices with a relay function.
The user equipment 101 is configured to determine that there is an untransmitted segmented packet in the UE and send a segmentation indication to the base station apparatus 102.
The segment indication is used for indicating the size of the segment data packet which is not transmitted in the first data packet to be transmitted and the identification of the first data packet to be transmitted. The base station device 102 is configured to receive a segment indication sent by the user device 101, and determine a size of a second data packet to be transmitted according to an identifier of the first data packet to be transmitted; the base station device 102 is further configured to determine a target network resource for allocating to the UE according to the size of the non-transmitted segmented data packet and the size of the second to-be-transmitted data packet.
The base station apparatus 102 is also configured to store various types of packet indication information; the data packet indication information includes an identifier of the data packet, content carried by the data packet, and a size of the data packet.
The user equipment 101 communicates with the base station equipment 102 via a network protocol stack. As shown in fig. 2, the network protocol stack includes a Service Data Adaptation Protocol (SDAP) layer, a Packet Data Convergence Protocol (PDCP) layer, a Radio Link Control (RLC) layer, a Medium Access Control (MAC) layer, and a Physical (PHY) layer.
Wherein, the PDCP layer communicates with the MAC layer through a logical channel of the RLC layer, and data received by the RLC layer from the PDCP layer or data transmitted to the PDCP layer is called RLC SDU or PDCP PDU; the data received by the RLC layer from the MAC layer or transmitted to the MAC layer is referred to as RLC PDU or MAC SDU. Here, a Protocol Data Unit (PDU) is used to indicate that data is transmitted according to a relevant protocol, and a Service Data Unit (SDU) is used to carry the transmitted data.
The following describes a resource determination method provided in an embodiment of the present invention in detail with reference to the accompanying drawings.
As shown in fig. 3, the resource determining method provided in the embodiment of the present invention includes the following steps S201 to S205:
s201, the UE determines that the non-transmission segmented data packet exists in the UE.
As a possible implementation manner, in the process of transmitting the first to-be-transmitted data packet, if the network resource allocated by the base station device does not enable the UE to send the first to-be-transmitted data packet at one time, the UE determines that there is a segmented data packet that is not transmitted in the UE after segmenting the first to-be-transmitted data packet.
It should be noted that, the UE reports a Buffer Status Reporting (BSR) to the base station device according to a network protocol, so as to indicate an 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 equipment allocates network resources to the UE according to the BSR reported by the UE and a preset scheduling algorithm. Under the condition that network resources are relatively tense, the network resources allocated to the UE by the base station device cannot satisfy the requirement that the UE sends all data packets at one time. Therefore, the UE may generate some fragmented packets during the transmission of the data.
The preset scheduling algorithm is preset in the base station equipment by operation and maintenance personnel.
Illustratively, 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, the data packet to be transmitted is divided into a data packet with a size of 1000 bits and a data packet with a size of 4000 bits. Further, the UE transmits a data packet with a size of 1000 bits through the network resource, and the data packet with the size of 4000 bits is stored in the UE as an untransmitted segmented data packet.
S202, the UE generates a segmentation indication.
The segmentation indication is used for indicating 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 a data packet to be transmitted where the segmented data packet is not transmitted; and the residual transmission information is used for reflecting the size of the section data packet which is not transmitted in the first data packet to be transmitted.
As a possible implementation manner, after determining that the untransmitted segmented data packets exist in the UE, the UE obtains the size of the untransmitted segmented data packets and an identifier of a first to-be-transmitted data packet in which the untransmitted segmented data packets are located. Further, the UE adds the identifier of the first to-be-transmitted packet and the size of the non-transmitted fragmented packet in the first to-be-transmitted packet to a Logical Channel Identifier (LCID) field in a Medium Access Control (MAC) -Control Element (CE) to generate a fragmentation indication.
As another possible implementation manner, the UE adds the identification of the first to-be-transmitted packet and the occupation ratio of the non-transmitted segmented packets in the first to-be-transmitted packet to the LCID field in the MAC-CE to generate the segmentation indication.
Note 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. The PN field is used for bearing the identification of the first data packet to be transmitted, and the PS field is used for bearing the residual transmission information of the first data packet to be transmitted.
Illustratively, in the case that the remaining transmission information is the occupation ratio of the non-transmitted segmented packets in the first to-be-transmitted packet, the value of the PN field is 20, which indicates that the occupation ratio of the non-transmitted segmented packets in the first to-be-transmitted packet is 20%.
As shown in table 1, the UE stores various types of indication information of the data packet to be transmitted, where the indication information includes an identifier of the data packet to be transmitted, a type of the data packet to be transmitted, and a size of the data packet. Table 1 specifies the size corresponding to a data packet to be transmitted carrying various contents, for example, a data packet to be transmitted carrying a picture, the size being 800 bits. Table 1 illustrates an exemplary packet indication information reference, and the present invention is not limited to the actual identification of the packet and the actual size of the packets to be transmitted in different types.
TABLE 1
| Identification of data packets to be transmitted | Type of data packet to be transmitted | Size of data packet to be transmitted |
| 1 | Picture frame | 800bit |
| 2 | Video | 1600bit |
| 3 | Audio frequency | 1000bit |
| … | … | … |
| n | Letter | 200bit |
In practical application, the UE may query the identifier of the first to-be-transmitted data packet and the size of the to-be-transmitted data packet from table 1 above according to the content carried in the first to-be-transmitted data packet.
For example, taking the type of the first to-be-transmitted packet as a picture, the size of the non-transmitted segmented packet in the first to-be-transmitted packet is 160 bits, and the remaining transmission information is an occupation ratio as an example, in combination with table 1, and when the packet is the picture packet in table 1, the PN field corresponds to 00000001, which reflects that the identifier of the first to-be-transmitted packet is 1; the PS field is 00010100, which reflects that the occupation rate of the fragment packets not transmitted in the first to-be-transmitted packet is 20%.
S203, the UE sends a segmentation indication to the base station equipment.
As a possible implementation manner, after generating the segmentation indication, the UE transmits the MAC-CE with the segmentation indication to the base station apparatus.
As another possible implementation manner, the UE may also send the MAC-CE with the segment indication to the base station device according to a preset period.
It should be noted that the preset period is set in the UE in advance by the operation and maintenance staff.
Correspondingly, the base station equipment receives the segmentation indication sent by the UE according to the network protocol.
S204, the base station equipment determines the size of the second data packet to be transmitted according to the identifier of the first data packet to be transmitted.
And 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, according to the identifier of the first to-be-transmitted data packet, the size of the second to-be-transmitted data packet.
It should be noted that the first to-be-transmitted data packet and the second to-be-transmitted data packet are to-be-transmitted data packets. The content carried by the second data packet to be transmitted may be the same as or different from the content carried by the first data packet to be transmitted. In general, the content carried by the second data packet to be transmitted is the same as the content carried by 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, and then the content carried by the second 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 in the UE.
For example, as shown in table 1, when the identifier of the first to-be-transmitted data packet is 1, the base station apparatus may determine that the size of the second data packet is 800 bits.
S205, the base station equipment determines target network resources for distributing the UE according to the size of the non-transmission segmented data packet and the size of the second to-be-transmitted data packet.
The target network resource is used for bearing the non-transmission segmented data package and at least one second data package to be transmitted.
As a possible implementation manner, the base station device determines the number of the at least one second to-be-transmitted data packet and determines the size of the at least one second to-be-transmitted data packet based on the maximum allocable network resource and the size of the non-transmitted segmented data packet. Further, the UE determines the sum of the size of the at least one second data packet to be transmitted and the size of the non-transmitted segmented data packet as the size of the target network resource.
The specific implementation manner of this step may specifically refer to the following description of the embodiment of the present invention, and is not described herein again.
It can be understood that after determining the size of the segment data packet which is not transmitted in the UE and the size of the second data packet to be transmitted, the base station device may determine, for the UE, a target network resource capable of bearing the segment data packet which is not transmitted and at least one second data packet to be transmitted according to the size of the segment data packet which is not transmitted and the size of the second data packet to be transmitted; thus, the determined network resources can be more suitable for the UE to transmit the data packet without segmentation.
In one design, when the remaining transmission information is an occupation ratio of the untransmitted segmented packets in the first to-be-transmitted packet, following S203, the following S301 to S302 are further included.
S301, the base station equipment determines the size of the first data packet to be transmitted.
As a possible implementation manner, the base station device queries the size of the first to-be-transmitted data packet according to the identifier of the first to-be-transmitted data packet.
S302, the base station equipment determines the size of the section data packet which is not transmitted according to the size of the first data packet to be transmitted and the residual transmission information.
As a possible implementation manner, the base station apparatus determines the product of the size of the first packet to be transmitted and the occupied proportion as the size of the segmented packet that is not transmitted.
For example, the size of the first to-be-transmitted packet is 800 bits, and the occupation ratio is 20%, then the size of the untransmitted segmented packet is: 800 bits 20% ═ 160 bits.
In one design, in order to determine a target network resource for allocation to the UE, S205 provided in the embodiment of the present invention specifically includes S2051 described below.
S2051, the base station equipment determines target network resources from the maximum allocable network resources allocated to the UE by the base station equipment according to the size of the non-transmitted segmented data packet and the size of the second to-be-transmitted data packet.
And the difference value between the maximum allocable network resource and the size of the non-transmitted segmented data packet is integral multiple of the size of the second data packet to be transmitted.
Illustratively, the maximum allocable network resource allocated to the UE by the base station device is 1000 bits, the size of the non-transmission segmented data packets is 160 bits, the size of each second data packet to be transmitted is 800 bits, and the number of the second data packets to be transmitted is 2. Since 1000-. At this time, the data packet transmitted by the UE is: the untransmitted segmented data packet 160bit + the second to-be-transmitted data packet 800bit is 960 bit. In this way, fragmentation of the UE during transmission of the data packet is avoided due to network resource limitations during subsequent transmissions.
In one design, after the above S205, the following S401 to S402 are further included.
S401, the UE determines the target network resource distributed by the base station equipment and the size of the second data packet to be transmitted.
And 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 for allocation 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.
