Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a message processing method and apparatus.
Background
In a User plane Protocol of a 5G (5th Generation Mobile Networks, fifth Generation communication technology) NR (New Radio technology), a Packet Data Convergence Protocol (PDCP), a Radio Link Control (RLC), a Media Access Control (MAC) layer, and a Transmission Control Protocol (TCP) are mainly included in the User plane Protocol.
When the UE is located at the cell edge, due To power limitation, one TCP packet cannot be transmitted within one TTI (Time To interval). Therefore, to reduce the error code, the currently adopted method is to reduce the amount of uplink data per subframe, and increase the power spectral density of each PRB by reducing PRBs, so that the base station is easier to demodulate.
However, this will result in the uplink TCP data being segmented at the RLC protocol layer, and the larger the TCP layer packet, the more segments. If some segments are lost in the air interface transmission process, the transmission of SDU (Service Data Unit) will be buffered in the base station, and further the processing delay of TCP message at the base station side will be increased.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Method embodiment one
Referring to fig. 1, a flowchart illustrating steps of an embodiment of a message processing method according to the present invention is shown, where the method is applicable to a base station device, and specifically may include:
and 104, establishing TCP connection with the terminal equipment based on the target maximum message length.
The base station device in the embodiment of the present invention may be a base station device in a 4G (4th generation) or 5G mobile communication network.
In the embodiment of the present invention, the base station device may receive a Power Headroom of the terminal device reported by the terminal device, and specifically, the base station device may receive a Power Headroom Report (PHR) reported by the terminal device. From the PHR, the transmit power state of the terminal device may be determined.
The PH (Power Headroom) refers to how much transmission Power is available for the terminal device in addition to the transmission Power used for the current PUSCH (Physical Uplink Shared Channel) transmission, and the unit of the PH is dB. The terminal device may report the PHR to the base station device to inform the base station device of the power headroom of the terminal device. The base station device can determine the current sending power state of the terminal device according to the power margin of the terminal device.
In an optional embodiment of the present invention, the determining the transmission power state of the terminal device according to the power headroom specifically includes the following steps:
if the value of the power margin is smaller than or equal to a preset value, determining that the sending power state of the terminal equipment is a first state; otherwise, determining the sending power state of the terminal equipment as a second state.
Wherein the first state is operable to indicate that the terminal device is in a power limited state. The second state may be used to indicate that the terminal device is in a non-power limited state. If the value of the power margin is smaller than or equal to a preset value, the power margin of the terminal equipment is low, and the terminal equipment reaches the maximum transmitting power, determining that the transmitting power state of the terminal equipment is a first state, otherwise, determining that the transmitting power state of the terminal equipment is a second state. The preset value may be 0, or may be a preset smaller value.
In order to solve the problem of power limitation of the terminal device, the number of Physical Resource Blocks (PRBs) to be scheduled may be reduced. However, this results in that one SDU needs to be segmented at the MAC layer for scheduling multiple times, resulting in increased delay.
In order to solve the problem, in the embodiment of the present invention, when it is determined that the transmission power state of the terminal device is the first state, in the process of establishing the TCP connection between the base station device and the terminal device, the maximum packet length in the handshake message is modified to the target maximum packet length.
The target maximum message length is a message length that can ensure that the TCP message can be scheduled at one time at the air interface.
The establishment of a TCP connection requires a three-way handshake across both parties. When the master side sends out a SYN (synchronization Sequence Numbers) connection request, the master side waits for the other side to answer SYN ACK (acknowledgement Character), and if the SYN ACK of the other side is received, the master side replies an ACK response to the other side, so that the master side and the slave side establish reliable TCP connection.
In the embodiment of the present invention, a message sent by both parties in the three-way handshake process is referred to as a handshake message, for example, the handshake message may include a SYN or SYN ACK type TCP packet. In the Options field of the TCP packet, an MSS (Maximum Segment Size) field is included, and this field is used to indicate the Maximum data length that each Segment can carry when the two parties of the transceiver negotiate for communication.
In the embodiment of the invention, under the condition that the sending power state of the terminal equipment is determined to be the first state, the maximum message length in the handshake message is modified in the process of establishing TCP connection with the terminal equipment. Specifically, the MSS field in the handshake message may be modified, the maximum packet length in the MSS field may be modified to the target maximum packet length, and based on the target maximum packet length, a TCP connection may be established with the terminal device.
Optionally, the modifying the maximum packet length in the handshake message to the target maximum packet length may be performed by modifying only the handshake message sent by one of the two parties that establish the TCP connection. The TCP protocol will automatically select the minimum MSS in the two-way handshake message to transmit data according to the negotiation.
Therefore, in the embodiment of the present invention, under the condition that the transmission power state of the terminal device is determined to be the first state, if the terminal device initiates a request for establishing a TCP connection, a handshake message in the process of establishing the TCP connection may be monitored, an MSS field in a SYN and SYN ACK message sent by one or both of the parties is modified to a target maximum message length, and then the modified handshake message is sent to the terminal device.
In an optional embodiment of the present invention, after establishing a TCP connection with the terminal device based on the target maximum packet length, the method may further include the following steps:
and transmitting a TCP message with the terminal equipment through the TCP connection, wherein the length of the TCP message does not exceed the length of the target maximum message.
Under the condition that the sending power state of the terminal equipment is in the first state, and after the base station equipment establishes the TCP connection with the terminal equipment, the base station equipment and the terminal equipment can transmit a TCP message through the TCP connection. In the process of establishing the TCP connection, the maximum message length in the handshake message is modified to the target maximum message length, and the target maximum message length is the message length which can ensure that the TCP message can be scheduled at one time at an air interface. In the process of transmitting the TCP message, the length of the TCP message does not exceed the target maximum message length, so that the size of the application layer SDU can be controlled by modifying the maximum message length in the handshake message, the condition that the TCP message is segmented in an RLC protocol layer can be avoided, and the increase of processing load and transmission delay caused by SDU segmentation can be further reduced.
In an optional embodiment of the present invention, after determining the transmission power state of the terminal device and before modifying the maximum packet length in the handshake message to the target maximum packet length, the method may further include:
step S11, determining the maximum transmission block size of the terminal equipment in the first state;
and step S12, determining the target maximum message length according to the maximum transmission block size.
It can be understood that the embodiment of the present invention does not limit the specific method for determining the target maximum packet. Optionally, when the transmit power state of the terminal device is in the first state, a maximum TBS (fransport block size) of the terminal device in the first state may be determined, and a target maximum packet length may be determined according to the maximum TBS.
Specifically, the maximum TBS of the terminal device in the first state may be determined by: assuming that the MCS _ init _ nonlimt is equal to the MCS (Modulation and Coding Scheme) level, the terminal equipment transmits a corresponding Modulation and Coding Scheme (MCS) level according to the expected power level of a single PRB, and ph (i) schedules the number of PRBs for the base station equipment to be Mpusch(i) When the PH power margin reported is over, the PRB _ MAX _ NOLimt reaches the power when the terminal equipment transmits according to the single PRB expected power levelThe number of PRBs that can be scheduled up to the maximum transmit power. Wherein PRB _ MAX _ NOLimt ═ Mpusch(i)×10PH(i)/10。
According to the PRB _ MAX _ NOLimt and the MCS _ init _ NOLimt, the current maximum TBS can be calculated or obtained by looking up a table and is TBS _ NOLimit, and therefore the maximum TBS which can be transmitted by the time interface when the terminal equipment is in the power limited state can be obtained.
Wherein, BS _ limit is the maximum transport block size that can be transmitted by the MAC layer of the air interface of the base station device, and the unit is bit, and it needs to be converted into bytes. The SDU size of the TCP application layer is MSS + TCP header length + IP header length + S byte size, and S is the RLC and MAC and PDCP protocol header byte number when one RLC PDU. Therefore, it can be determined that the target maximum packet length is: (Byte) TBS _ notimit-S-TCP header length-IP header length.
In an optional embodiment of the present invention, after modifying the maximum packet length in the handshake message to the target maximum packet length, the method may further include:
step S21, recording the original maximum message length before modification;
step S22, monitoring the sending power state of the terminal equipment;
step S23, if it is monitored that the transmission power state of the terminal device is the second state, sending a message length recovery notification to the terminal device, so as to notify the terminal device to send a TCP message according to the original maximum message length.
After determining that the sending power state of the terminal device is the first state and modifying the maximum message length in the handshake message to the target maximum message length, the embodiment of the present invention may record the original maximum message length before modification, and monitor the sending power state of the terminal device. If the sending power state of the terminal equipment is monitored to be the second state, the terminal equipment is in a non-power limited state, and the maximum message length of the TCP message can be recovered at the moment. The base station device may send a message length recovery notification to the terminal device to notify the terminal device to send a TCP message according to the original maximum message length.
In an optional embodiment of the present invention, the sending a message length recovery notification to the terminal device specifically may include:
step S32, judging whether a TCP connection is established with the terminal equipment;
step S32, if TCP connection is established with the terminal device, sending a control message protocol ICMP message to the terminal device, wherein the ICMP message carries the original maximum message length;
step S33, if the TCP connection is not established with the terminal device, modifying the maximum packet length in the handshake message to the original maximum packet length in the process of establishing the TCP connection with the terminal device.
When the transmission power state of the terminal device is monitored to be the second state, the terminal device may still maintain the established TCP connection with the base station device, or the terminal device may disconnect the established TCP connection with the base station device. Therefore, it is necessary to determine whether a TCP connection is established with the terminal device, and if the TCP connection is established between the base station device and the terminal device, the base station device may send an ICMP (Internet Control Message Protocol) Message to the terminal device to notify the terminal device of recovering the maximum Message length of the TCP Message, where the ICMP Message carries the original maximum Message length.
In practical application, the ICMP message may be used to notify an MTU (Maximum Transmission Unit) of a router in a Transmission network, and a sender is required to transmit data according to the MTU of the router. After the terminal device receives the ICMP message sent by the base station device, the terminal device may send a TCP message according to the original maximum message length specified in the ICMP message.
If the base station device and the terminal device do not establish TCP connection, the maximum message length in the handshake message is modified to the original maximum message length in the process of establishing transmission control protocol TCP connection with the terminal device.
Therefore, the embodiment of the invention can calculate the maximum TBS which can be dispatched by the MAC when the power of the terminal equipment is determined to be limited. On this basis, the maximum message length of the TCP message carried on the RB is adjusted through the TBS size, so that the size of the SDU message generated by the TCP can be limited, and the message can be scheduled at one time at an air interface to the greatest extent. And when the power of the terminal equipment is monitored to be not limited, a message length recovery notice can be sent to the terminal equipment. It can be seen that, by the embodiment of the present invention, the size of the MSS can be dynamically adjusted according to the transmission power state of the terminal device, so that the size of the transmission packet can be adaptive to the network state of the terminal device, the SDU transmission delay can be reduced, and the transmission efficiency can be improved.
Method embodiment two
Referring to fig. 2, a flowchart illustrating steps of another embodiment of a message processing method according to the present invention is shown, where the method is applicable to a base station device, and specifically may include:
if the PH of the terminal device is less than or equal to 0, it may be determined that the transmission power state of the terminal device is a first state (power limited state), and at this time, the maximum transport block size of the terminal device in the first state may be calculated.
if the PH of the terminal device is greater than 0, it may be determined that the transmission power state of the terminal device is a second state (non-power-limited state), and at this time, it may be determined whether a TCP connection is established with the terminal device.
To sum up, in the embodiment of the present invention, when it is determined that the transmission power state of the terminal device is the first state, the maximum packet length of the TCP packet may be automatically adjusted, so as to limit the size of an SDU packet generated by TCP, ensure that the TCP packet can be scheduled at an air interface at one time, reduce the occurrence of a situation that the TCP packet is segmented in an RLC protocol layer, and further reduce the increase of processing load and transmission delay caused by SDU segmentation.
