The communication control method of the embodiment of the application is applied to a terminal 1, the terminal 1 can be electronic equipment such as a mobile phone, a personal computer, a tablet personal computer and the like, the terminal 1 can interact with a network device 2, and the network device 2 can be communication service equipment such as a base station and the like. The method comprises the following steps: s10, the network device 2 sends a first configuration message to the terminal 1, and the terminal 1 receives the first configuration message, where the first configuration message is used to determine a communication parameter of the communication between the terminal 1 and the network device 2. Specifically, the first configuration message may include transmission parameters for negotiating transmission data packets when the terminal 1 interacts with the network device 2. For example, the transmission parameter may be a parameter related to the fact that when the radio resource control layer (Radio Resource Control, RRC) initiates a new PDCP SDU to the packet data convergence protocol layer (Packet Data Convergence Protocol, PDCP) during communication between the terminal 1 and the network device 2, the PDCP starts a Discard Timer (Discard Timer) for each SDU.
The network device 2 may determine that the transmission parameters for the transmission data packet may be negotiated with the network device 2 when the terminal 1 determines that the first indication information for negotiating the transmission parameters for the transmission data packet is included after receiving the first configuration message. S20, after determining that the current communication information of the terminal 1 and the network equipment 2 meets the target condition, sending a first request message to the network equipment 2 based on the self communication requirement of the terminal 1; wherein the first request message includes second indication information of the target transmission parameter that the terminal 1 requests to use. For example, the target transmission parameter may be a relevant parameter of a discard timer determined by the terminal 1 according to the current own communication requirement. S30, after the terminal 1 sends the target transmission parameter to the network device 2, the network device 2 may reconfigure the transmission parameter of the transmission data packet based on the target transmission parameter, so that the transmission parameter of the transmission data packet reconfigured when the network device 2 communicates with the terminal 1 may meet the requirement of the terminal 1. Therefore, the terminal 1 can be adapted to different types of network equipment 2, the communication quality with the different types of network equipment 2 is improved, and the user experience is improved.
The following describes in detail the communication control method according to the embodiment of the present application with reference to the accompanying drawings, where the method is applied to a terminal 1, such as a mobile phone, a computer, etc., and can perform data interaction with a network device 2, such as a base station, etc., as shown in fig. 1 and with reference to fig. 5, and the method includes the following steps:
s100, receiving a first configuration message sent by the network equipment 2.
For example, the data packets may be transmitted between the terminal 1 and the network device 2 through a cellular network protocol, where a corresponding communication Link has a plurality of data layers, such as a Radio resource control layer (Radio Resource Control, RRC), a packet data convergence protocol layer (Packet Data Convergence Protocol, PDCP), a Radio Link control RRC, RLC, etc. Each data layer has its own role.
The terminal 1 needs to determine the transmission parameters used during the data interaction with the network device 2. The transmission parameters include transmission modes of different data types in the data transmission process, channels used in the data transmission process, a Discard (Discard) mechanism adopted for preventing buffer overflow of at least one data layer, and the like. After determining the transmission parameters, the terminal 1 and the network device 2 may use the transmission parameters for transmitting data packets during the mutual communication.
In one implementation, the network device 2 sends a first configuration message to the terminal 1, the first configuration message being used to determine parameters of the communication between the terminal 1 and the network device 2. The transmission parameters included in the first configuration message may be parameters used by the network device 2 by default. After receiving the first configuration parameters, the terminal 1 may determine whether to use the transmission parameters included in the first configuration message according to its own requirements, or transmit its own requirements to the network device 2.
S200, determining that the current communication information of the terminal 1 and the network equipment 2 meets a target condition and sending a first request message to the network equipment 2 when the first configuration message comprises first indication information of transmission parameters of a transmission data packet;
wherein the first request message includes second indication information of a target transmission parameter that the terminal 1 requests to use, so that the network device 2 reconfigures transmission parameters of a transmission data packet based on the second indication information.
Illustratively, after receiving the first configuration message sent by the network device 2, the terminal 1 analyzes the content of the first configuration message. And judging whether the data in the first configuration message has first indication information for negotiating transmission parameters of the transmission data packet. Specifically, the first indication information is related information for indicating negotiation between the terminal 1 and the network device 2 to transmit the data packet, and at least includes an indication of a negotiation mechanism and an indication of a transmission parameter of the data packet.
In case the terminal 1 determines that the first configuration message includes the first indication information for negotiating the transmission parameters of the transmission data packet, it may be determined that the network device 2 may negotiate for its current communication information with the terminal 1 and give default transmission parameters. Further, it is determined whether the current communication information between the terminal 1 and the network device 2 meets the target condition, for example, whether the current communication information between the network device 2 meets the target condition according to the type of the transmission data of the network device 2, the stability of the transmission of the data packet, and the like. If it is determined that the current communication information of the terminal 1 satisfies the target condition, a first request message is sent to the network device 2.
The first request message includes second indication information of the target transmission parameter that the terminal 1 requests to use, and requests to the network device 2 to use the target transmission data. Specifically, the terminal 1 may construct the second instruction information according to its own usage scenario and user requirements, and the target transmission parameter in the constructed second instruction information is adapted to the current usage state of the terminal 1. For example, the target transmission parameter is a discard timer parameter of the data layer to which the current terminal 1 is applicable. After receiving the first request message, the network device reconfigures the transmission parameters of the transmission data packet by using the target transmission parameters based on the indication of the second indication information, for example, the currently used transmission parameters can be configured as the target transmission parameters adapted to the terminal 1.
The communication control method of the embodiment of the invention is based on the negotiation mechanism of the network equipment 2 and the terminal 1 about the transmission parameters of the transmission data packet, so that the transmission parameters of the transmission data packet can be reconfigured when the network equipment 2 communicates with the terminal 1 and is adapted to the current requirement of the terminal 1, thereby the terminal 1 can be adapted to different types of network equipment 2, the communication quality of the network equipment 2 of different types is improved, and the user experience is improved.
In one embodiment of the present application, the transmission parameters include a discard timer parameter, where the discard timer parameter is used to perform a data timing operation on a data packet sent from the radio resource control layer to the packet data convergence protocol layer.
For example, when the network device 2 is a network base station, the terminal 1 and the network device 2 may transmit data packets through a cellular network protocol, where a corresponding communication Link has a plurality of data layers, such as a Radio resource control layer (Radio Resource Control, RRC) to a packet data convergence protocol layer (Packet Data Convergence Protocol, PDCP), radio Link control RRC, RLC, and the like. Each data layer has its own role.
PDCP is an L2 layer protocol, located between RRC and RLC. Is mainly responsible for the safety, reliability and efficiency of packet data transmission. To prevent buffer overflow, PDCP implements a Discard (Discard) mechanism for PDCP SDUs. When the RRC layer initiates a new PDCP SDU to the PDCP layer, the PDCP starts a Discard Timer (Discard Timer) for each SDU. When the timer expires or the PDCP SDU has been successfully transmitted by the PDCP status report, the PDCP discards the corresponding PDCP SDU and its associated PDCP PDU.
The transmission parameters include a discard timer parameter of a discard timer for performing a data timing operation on a data packet transmitted from the radio resource control layer to the packet data convergence protocol layer.
When a radio resource control layer (RRC layer) initiates a new PDCP SDU to a packet data convergence protocol layer (PDCP layer), the PDCP layer starts a discard timer number for each SDU for data timing operations. Specifically, the PDCP layer determines a time to discard the corresponding PDCP SDU and its associated PDCP PDU by a discard timer parameter.
The determining that the current communication information between the terminal 1 and the network device 2 meets the target condition, as shown in fig. 2, includes:
s210, determining a target discard timer parameter corresponding to the data type of the transmission data packet.
Illustratively, the transport packets have multiple data types, and the target discard timer parameters for different data type adaptations are different. For example, when the user uses the terminal 1, in the process of interacting with the network device 2 such as a base station, the data types of the transmission data packet that may be involved include IMS signaling data, call data, and game data. Different data types differ for the time that the PDCP layer discards the corresponding PDCP SDU and its associated PDCP PDU. For example, call data may require a relatively low data transmission rate compared to game data, which may require a relatively high data transmission rate. The target discard timer parameter adapted to the call data is thus greater than the target discard timer parameter adapted to the game data.
According to specific application requirements, further expansion, when IMS signaling data is transmitted between the terminal 1 and the network device 2 such as a base station, a target Discard timer parameter (Discard timer) may be set to be Infinity, which is 3000ms. Thereby improving the call completing rate; when call data is transmitted between the terminal 1 and the network equipment 2 such as a base station, a target Discard timer parameter (Discard timer) can be set to 300ms, so that the call quality is improved; when the game data is transmitted between the terminal 1 and the network device 2 such as a base station, a target Discard timer parameter (Discard timer) may be set to be less than 100ms, so as to enhance the game experience.
S220, if the discard timer parameter in the first indication information is different from the target discard timer parameter, determining that the target condition is met.
Illustratively, the discard timer parameter in the first indication information may be a discard timer parameter used by default by the network device 2, while also allowing negotiation with the terminal 1 regarding the discard timer parameter. After the terminal 1 obtains the first indication information, comparing the discard timer parameter with the target discard timer parameter, wherein the target discard timer parameter is matched with the data type of the data packet transmitted by the current terminal 1. If the discard timer parameter in the first indication information is different from the target discard timer parameter after comparison, the default discard timer parameter of the network device 2 is not matched with the data type of the data packet transmitted by the current terminal 1. And further, the terminal 1 is determined to meet the target condition, and the adjustment of the discard timer parameter can be performed in time.
In one embodiment of the present application, the determining that the current communication information between the terminal 1 and the network device 2 meets the target condition, as shown in fig. 3, includes:
s230, obtaining data packet loss rate and/or jitter data information between the network equipment 2 and the terminal 1;
S240, if the packet loss rate and/or the jitter data information is greater than a first threshold value, determining that the target condition is met.
For example, during the interaction of the network device 2, the terminal 1 may have phenomena of packet loss and data jitter during the transmission of the data packet due to hardware configuration or other factors, and may cause data transmission errors in severe cases. One of the reasons for the phenomena of packet loss and data jitter during the transmission of data packets is that the discard timer parameters used by the network device 2 and the terminal 1 during the data transmission are not appropriate. Therefore, in this embodiment, after obtaining the data packet loss rate and/or jitter data information between the network device 2 and the terminal 1, the information is compared with the first threshold, if the packet loss rate and/or jitter data information is greater than the first threshold, it is determined that the phenomena of packet loss and data jitter in the process of transmitting the data packet are serious, and then it is determined that the currently used discard timer parameter is not appropriate. And further, the current situation of the terminal 1 is determined to meet the target condition, and the adjustment of the discarding timer parameter can be performed in time.
In one embodiment of the present application, the method further comprises the steps of: and controlling transmission of the data packet based on the default transmission parameters in the first configuration message under the condition that the first configuration message does not comprise the first indication information of the transmission parameters of the negotiation transmission data packet.
Illustratively, the network device 2 may or may not negotiate a use configuration message with the terminal 1 (including the transmission parameters in the use configuration message). After receiving the first configuration message sent by the network device 2, if it is determined that the first configuration message does not include the first indication information for negotiating the transmission parameters of the transmission data packet, the terminal 1 determines that the network device 2 does not negotiate with the terminal 1 to use the configuration message, but controls the terminal 1 to control the transmission of the data packet using the default transmission parameters in the first configuration message. The terminal 1 does not send the first request message to the network device 2 anymore but uses the default transmission parameters in the first configuration message to control the transmission of the data packets.
In one embodiment of the present application, the first indication information is set in non-critical extension information of a reconfiguration channel in a radio resource control layer, so as to allow the terminal 1 to negotiate with the network device 2 about transmission parameters of a transmission data packet.
Illustratively, the network device 2 and the terminal 1 transmit data packets through a cellular network protocol, where the communication Link corresponding to the cellular network protocol has a plurality of data layers, including a Radio resource control layer (Radio Resource Control, RRC), a packet data convergence protocol layer (Packet Data Convergence Protocol, PDCP), a Radio Link layer (Radio Link control RRC, RLC), a medium access control layer (Medium Access Control, MAC), and an ethernet physical layer (Port Physical Layer, PHY). Each data layer has its own role.
The radio resource control layer is used for carrying out radio resource management, control and scheduling by a certain strategy and means, and fully utilizing limited radio network resources as far as possible under the condition of meeting the requirement of service quality. The radio resource control layer has a reconfiguration channel Reconfiguration IE (Information Element) therein, the reconfiguration channel having non-critical extension information, and the network device 2 may set the first indication information in the non-critical extension when transmitting the first indication information to the terminal 1. For example, PDCP-discard timer-negotiator (supported or not supported) may be added to non-critical extension to characterize whether the network device 2 (e.g., base station) supports PDCP Discard timer negotiation.
In one embodiment of the present application, the second indication information is set in terminal assistance information of a dedicated control channel in a radio resource control layer.
The terminal 1 sends a first request message to the network device 2 during the process of negotiating the target transmission parameters to be used by the network device 2; the first request message includes second indication information of the target transmission parameter that the terminal 1 requests to use. The second indication information is set in terminal assistance information (UEAssistanceInformation, UAI) of a dedicated control channel (DedicatedControlChannel, UL _dcch) in a radio resource control layer (Radio Resource Control, RRC).
For example, in the 4G/5G network communication process between the terminal 1 and the base station, the UE assuredly information of the UL DCCH of the RRC layer of the 4G/5G network is extended, so as to allow the terminal 1 (UE) to initiate PDCP discard timer negotiation to the network; ue assistance information is a message from terminal 1 to base station newly added by RRC in 3gpp r16, and the purpose is to dynamically negotiate parameters with the base station after rrcrecon configuration so that the base station can better allocate appropriate resources to terminal 1.
The embodiment of the application also provides a processing method of communication data of the communication control method, which is applied to the network device 2, as shown in fig. 4 and combined with fig. 5, and the method comprises the following steps:
s300, a first configuration message is sent to the terminal 1, wherein the first configuration message comprises first indication information for indicating transmission parameters of a discard timer for negotiating to send transmission data packets;
s400, acquiring a first request message of the terminal 1, wherein the first request message comprises second indication information of a target transmission parameter which is requested to be used by the terminal 1;
s500, a second configuration message is sent, wherein the second configuration message comprises the data packet transmission parameters reconfigured based on the target transmission parameters.
For example, the data packets may be transmitted between the terminal 1 and the network device 2 through a cellular network protocol, where a corresponding communication Link has a plurality of data layers, such as a Radio resource control layer (Radio Resource Control, RRC), a packet data convergence protocol layer (Packet Data Convergence Protocol, PDCP), a Radio Link control RRC, RLC, etc. Each data layer has its own role.
The terminal 1 needs to determine the transmission parameters used during the data interaction with the network device 2. The transmission parameters include transmission modes of different data types in the data transmission process, channels used in the data transmission process, a Discard (Discard) mechanism adopted for preventing buffer overflow of at least one data layer, and the like. After determining the transmission parameters, the terminal 1 and the network device 2 may use the transmission parameters for transmitting data packets during the mutual communication.
In one implementation, the network device 2 sends a first configuration message to the terminal 1, the first configuration message being used to determine parameters of the communication between the terminal 1 and the network device 2. The transmission parameters included in the first configuration message may be parameters used by the network device 2 by default. After receiving the first configuration parameters, the terminal 1 may determine whether to use the transmission parameters included in the first configuration message according to its own requirements, or transmit its own requirements to the network device 2.
After the network device 2 sends the first configuration message to the terminal 1, the terminal 1 analyzes the content of the first configuration message. And judging whether the data in the first configuration message has first indication information for negotiating transmission parameters of the transmission data packet. Specifically, the first indication information is related information for indicating negotiation between the terminal 1 and the network device 2 to transmit the data packet, and at least includes an indication of a negotiation mechanism and an indication of a transmission parameter of the data packet.
In case the terminal 1 determines that the first configuration message includes the first indication information for negotiating the transmission parameters of the transmission data packet, it may be determined that the network device 2 may negotiate for its current communication information with the terminal 1 and give default transmission parameters. Further, it is determined whether the current communication information between the terminal 1 and the network device 2 meets the target condition, for example, whether the current communication information between the network device 2 meets the target condition according to the type of the transmission data of the network device 2, the stability of the transmission of the data packet, and the like. If it is determined that the current communication information of the terminal 1 satisfies the target condition, a first request message is transmitted to the network device 2, and the network device 2 acquires the first request message transmitted by the terminal 1.
The first request message includes second indication information of the target transmission parameter that the terminal 1 requests to use, and the terminal 1 requests to use the target transmission data to the network device 2. Specifically, the terminal 1 may construct the second instruction information according to its own usage scenario and user requirements, and the target transmission parameter in the constructed second instruction information is adapted to the current usage state of the terminal 1. For example, the target transmission parameter is a discard timer parameter of the data layer to which the current terminal 1 is applicable. After receiving the first request message, the network device reconfigures the transmission parameters of the transmission data packet by using the target transmission parameters based on the indication of the second indication information, for example, the currently used transmission parameters can be configured as the target transmission parameters adapted to the terminal 1.
The network device 2 sends a second configuration message to the terminal 1 based on the acquired first request message, wherein the second configuration message comprises the data packet transmission parameters reconfigured based on the target transmission parameters. For example, the packet transmission parameter is the target transmission parameter itself, so as to meet the requirements of the terminal 1.
In one embodiment of the present application, the data packet transmission parameter reconfigured based on the target transmission parameter includes:
