Description
Technical Field
The invention relates to a 5G mobile terminal, in particular to a method and a device for improving NR eMBB service transmission performance and a mobile terminal.
Background
A fifth generation mobile communication technology (5th generation mobile networks, 5G) network can meet three major types of requirements, the first type is enhanced mobile broadband communication (eMBB), the second type is ultra-reliable low-delay communication (URLLLC), the third type is large-scale machine communication (eMTC), and the NR eMBB service has the following problem to be optimized:
(1) the 5G mobile terminal needs to support eMBB ultra-high-number-rate service, and the number rate required to be supported by the 5G mobile terminal is higher and higher, so that the CPU is subjected to very high load when the CPU processes the ultra-high number rate, resources reserved for the upper-layer APP application to use the CPU are reduced, and the phenomenon that a user possibly feels slow is shown. One reason for the CPU load being too high is: the CPU resource needs to process the header of each IP layer packet (for example, segmentation and reassembly), the more the number of processed IP packets is, the more CPU resource is consumed, but the Maximum data of each IP packet is determined by a Maximum Transmission Unit (MTU), which is usually a fixed value of 1500 bytes.
(2) Each IP packet consists of an IP header (of fixed size, typically 20 bytes for IPv4 header and 40 bytes for IPv6 header) and a data portion, so if each packet is transmitting less data and less efficient, e.g. a packet consists of 20 bytes header and 10 bytes of data, then the actual data being transferred is only 10 bytes and the IP header data exceeds the data portion.
(3) If more IP packets are available, PDU data can be segmented or concatenated in the modem protocol stack (RLC/MAC layer), which can increase the load of RLC and MAC layers.
(4) On the other hand, the service range supported by 5G is very wide, so the requirement range for the rate is very wide, for example, how many G per second is required for downloading ultra-high definition video, while the rate of 5G internet-of-things equipment, such as a remote water meter, may be only several kpbs, but all use a fixed MTU value (usually 1500 bytes).
Therefore, the prior art has defects and needs to be improved and developed.

As shown in fig. 1, a specific procedure of the method for improving the transmission performance of the NR eMBB service may be as follows:
101. and sending information supporting the maximum transmission unit negotiation to the core network.
For example, when the 5G mobile terminal processes the NR eMBB service and the user equipment registers the network, the 5G mobile terminal first exchanges capability information with the network. The user equipment sends information supporting negotiation of the maximum transmission unit to the core network.
Wherein, the user equipment carries the parameter supporting the maximum transmission unit negotiation in the REGISTRATION REQUEST (REGISTRATION REQUEST) message to the core network, and the core network knows that the user equipment has the capability of supporting the maximum transmission unit negotiation.
102. Receiving the parameter of the maximum transmission unit supporting negotiation sent by the core network, and judging that the core network supports the maximum transmission unit supporting negotiation.
For example, after receiving the information supporting the negotiation maximum transmission unit sent by the user equipment, the core network sends the information supporting the negotiation maximum transmission unit to the user equipment, and the user equipment receives the information and determines that the core network supports the negotiation maximum transmission unit.
The core network sends information supporting the negotiated maximum transmission unit to the user equipment, that is, the REGISTRATION acceptance (REGISTRATION ACCEPT) message carries a parameter supporting dynamic negotiation to the user equipment, and the user equipment knows that the core network has the capability of supporting the negotiated maximum transmission unit.
And if the user equipment and the core network both support the negotiation of the maximum transmission unit, continuing the following method flow, otherwise, exiting.
103. And receiving inquiry information sent by a base station, and sending the information supporting the maximum transmission unit negotiation to the base station.
For example, the base station queries the capability information of the ue, and the ue receives the query information sent by the base station and sends information supporting negotiation of the maximum transmission unit to the base station. The capability information refers in the embodiments of the present invention to the capability of supporting negotiation of the maximum transmission unit.
The UE sends Information supporting negotiation of the mtu to the base station, that is, the UE Capability Information (UE Capability Information) carries parameters supporting negotiation of the mtu to the base station. The base station also knows that the user equipment has the capability to support negotiating the maximum transmission unit.
104. And receiving the physical layer resource distributed by the base station, and determining the physical layer resource according to the information supporting the maximum transmission unit negotiation.
For example, the base station allocates physical layer resources to the user equipment, where the physical layer resources include time-frequency resources, and the base station determines the physical layer resources corresponding to the user equipment according to information supporting negotiation of a maximum transmission unit sent by the user equipment. The user equipment receives the physical layer resource allocated by the base station.
In the embodiment of the present invention, the information supporting the negotiated maximum transmission unit includes whether the user equipment has the capability of supporting the negotiated maximum transmission unit, the size of the capability of supporting the negotiated maximum transmission unit, and the like; the sizes of the capabilities of the maximum transmission units supporting negotiation are different, and the physical layer resources allocated to the corresponding user equipment by the base station can also be different, so that the physical layer resources corresponding to the user equipment are determined according to the information of the maximum transmission units supporting negotiation.
The embodiment of the invention aims at the NR eMBB service, and compared with other NR services and 2G/3G/4G services, the NR eMBB service has more time-frequency resources distributed to user equipment by a base station in a physical layer.
105. And reporting the physical layer resource, and determining the maximum transmission unit value according to the physical layer resource.
For example, after receiving the physical layer resource allocated by the base station, the user equipment reports the physical layer resource, and determines the maximum transmission unit value according to the amount of the received physical layer resource.
After receiving physical layer (PHY) resources, the user equipment reports the physical layer resources to a medium access layer (MAC), acquires a first Protocol Data Unit (PDU) of the medium access layer, and determines a first protocol data unit value according to the structure of the first protocol data unit; reporting the value of the first protocol data unit to a radio link control layer protocol layer (RLC), acquiring a second protocol data unit of the RLC, and determining the value of the second protocol data unit according to the structure of the second protocol data unit; reporting the second protocol data unit value to a packet data convergence protocol layer (PDCP), acquiring a third protocol data unit of the PDCP, and determining a third protocol data unit value according to the structure of the third protocol data unit; reporting the value of the third protocol data unit to a service data adaptation protocol layer (SADP), acquiring a fourth protocol data unit of the SADP, and determining the value of the fourth protocol data unit according to the structure of the fourth protocol data unit; and finally, calculating the maximum transmission unit value according to the fourth protocol data unit value and an Internet Protocol (IP) structure.
As shown in fig. 2, fig. 2 is a flow of sending data by a protocol stack and a data format corresponding to each layer, an IP structure includes an IP header and IP data, data transmission is from top to bottom, header data of the protocol layer is newly added every time a protocol layer passes through, and data passed down by a previous layer becomes a data portion of the layer. In the invention, after physical layer resources are confirmed, the physical layer resources are sequentially moved upwards, and finally IP data are calculated, namely the maximum transmission unit value is obtained through calculation.
After the user equipment determines the maximum transmission unit value, the maximum transmission unit value is sent to the base station through the radio resource control message, and the base station sends the received maximum transmission unit value to the core network. After the 5G base station and the user plane function of the core network receive the maximum transmission unit value adjusted by the user equipment, the subsequent user plane functions of the user equipment, the base station and the core network uniformly process IP data packets according to the adjusted maximum transmission unit value, and the base station and the UE protocol stack are equivalent, so that the base station processes the IP data packets according to the flow of the UE side, thereby reducing the number of the IP data packets, increasing the maximum data carried by each IP data packet and improving the overall transmission efficiency of the NR eMBB service in the 5G network.
The maximum transmission unit value is dynamically adjusted according to the physical layer resources allocated by the base station, and when the physical layer resources allocated by the base station are more, the maximum transmission unit value is increased more; and updating the maximum transmission unit value according to the physical layer resource. The user equipment sends the updated maximum transmission unit value to the base station, and the base station sends the updated maximum transmission unit value to the user plane function of the core network.

The UE sends Information supporting negotiation of the maximum transmission unit to the base station, that is, the UE Capability Information (UE Capability Information) carries parameters supporting negotiation of the maximum transmission unit to the base station. The base station also knows that the user equipment has the capability to support negotiating the maximum transmission unit.
