Detailed Description
To make the objects, technical solutions and advantages of the present application more clear, embodiments of the present application will be described in further detail below with reference to the accompanying drawings.
For convenience of understanding, terms referred to in the embodiments of the present application are explained below.
Application Processor (AP): the terminal is a chip for processing data in the terminal, and the terminal can run a system, an application program and the like through an application processor, and can also monitor the system, the application program and the like through the application processor.
Baseband chip (Baseband Processor, BP): the chip is used for processing communication in the terminal and is responsible for realizing a network bottom layer transmission protocol, and the terminal can generate and send a data packet through a Modem (Modem) of the baseband chip.
Internet Packet explorer (Packet Internet Groper, PING): is a command under the Windows, Unix and Linux systems for a program for testing the amount of network connection. PING also belongs to a communication protocol and is part of the TCP/IP protocol. It is possible to check whether the network is connected or not using PING.
Low latency property: refers to the property of an application that is sensitive to communication latency. The working state of the application with low latency attribute depends on the communication speed, for example, social software with praise function. If the communication delay is longer, the server will receive the approval request after the user completes the approval for a longer time, so that the feedback time is longer, and the user experience is poorer.
Radio Link Control protocol (RLC): is a protocol layer of a radio bearer in Long Term Evolution (LTE). In LTE, the RLC layer is located above the Media Access Control (MAC) layer, belongs to a part of the protocol layer of the radio bearer, and provides segmentation and retransmission services for user and Control data.
Radio Resource Control (RRC): the third layer of the protocol layer of the LTE wireless access radio bearer is responsible for processing the third layer information of the control plane between the terminal and the access network equipment.
Protocol Data Unit (PDU): is the information loaded by each layer protocol stack when a data packet is transmitted in a layered network structure.
Connected state (connected): the terminal can carry out the working state of data transmission at any time.
Idle (idle): when the terminal has a data transmission requirement, the connection needs to be established first and then the working state of data transmission needs to be established.
For the user, the network delay of the application program is mainly perceived as the following three reasons: (1) the server processes the delay caused by the data, and the time is consumed from the time of receiving the data packet of the application program to the time of returning; (2) the terminal locally calculates various data, renders pictures, and processes the time consumed by the work of user interaction behavior and the like; (3) and the communication delay comprises the delay from the terminal to the access network equipment through an air interface and the delay from the transmission of the data packet from the access network equipment to the server.
The communication delay is the main reason that a user feels the network delay, and is obtained through a large amount of tests and calculations by the applicant through research, and the main reason of the communication delay is that the terminal needs to continuously reestablish RRC connection with access network equipment when the terminal is in an idle state, so that the delay is long.
If the terminal is currently in a connected state and a data packet is not sent to the access network device within a preset timeout duration, the access network device releases the RRC connection with the terminal. At this time, the terminal switches from the connected state to the idle state. When the terminal needs to transmit uplink data, the terminal needs to request to reestablish RRC connection with the access network device, and the terminal is switched from an idle state to a connected state after the RRC connection is reestablished.
In the above method, after the RRC connection between the terminal and the access network is released, it takes a long time to reestablish the RRC connection, resulting in a long service delay.
In view of the above problems, embodiments of the present application will provide a solution to a communication delay problem caused by the fact that the terminal needs to continuously re-establish an RRC connection with the access network device in an idle state, so as to accelerate a communication speed between the terminal and the access network.

Optionally, the server 130 is connected to the access network device 120 through a communication network. Optionally, the communication network is a wireless network or a wired network.
Referring to fig. 2, a protocol layer structure diagram of a radio bearer according to an exemplary embodiment of the present application is shown. The access network device 140 and the terminal 120 are respectively configured with an Internet Protocol (IP) layer, a Packet Data Convergence Protocol (PDCP) layer, an RLC layer, an MAC layer, and a Physical (PHY) layer, which are interconnected between networks and are supported by radio bearers, and when a piece of signaling or Data is transmitted from the access network device 120 to the terminal 110 through the radio bearers, after the access network device 120 sequentially passes through the PDCP layer, the RLC layer, the MAC layer, and the PHY layer, the signaling or Data is transmitted to the terminal 110 through the radio bearers, and then the access network device 120 sends the signaling or Data to the terminal 110 through a radio frequency unit of the access network device 120, and the signaling or Data is received by a radio frequency unit of the terminal 110 and sequentially passes through the PHY layer, the MAC layer, the PLC layer, and the PDCP layer of the terminal 110 for processing. Accordingly, when a piece of signaling or data is transmitted from the terminal 110 to the access network device 120 through the radio bearer, the processing order of the protocol layers is reverse to the above order.
Referring to fig. 3, a flowchart of a method for communication acceleration according to an exemplary embodiment of the present application is shown, where as shown, the method is applied to the terminal 110 shown in fig. 1, and the method includes:
Optionally, the application processor monitors an application program running in the terminal, and when it is detected that a data packet transmitted by the application program running in the terminal has a low latency attribute, determines that the application program transmitting the data packet has the low latency attribute, and sends a PING data packet sending request to the baseband chip.
Optionally, the application processor monitors an application running in the terminal, and when detecting that the application with a low delay attribute is started, sends a PING packet sending request to the baseband chip.
Optionally, the PING data packet sending request sent by the application processor to the baseband chip carries a predetermined time interval and/or a sending time.
The preset time interval is the time interval between two consecutive PING data packets, and the sending time is the duration of sending the ACK data packet. Typically the predetermined time interval is less than the transmission time.
For example, when the user sends the PING packets at intervals within a period of time by the application, the period of time during which the PING packets are sent is the duration of the activity.
And step 302, the baseband chip generates a PING data packet in an RLC layer according to the PING data packet sending request.
After receiving a PING data packet sending request sent by the application processor, the baseband chip generates a PING data packet in the RLC layer according to the sending request.
And sending a PING data packet to the access network equipment to enable the terminal and the access network equipment to be always in a connected state, and maintaining the RRC connection between the terminal and the access network equipment.
For example, each time a packet passes through a protocol stack in a layered network structure, the protocol stack will load PDUs of the layer in the packet. The RLC layer is provided with a retransmission mechanism, a data packet sent by a server and a terminal is stored in a cache of the access network equipment, when the access network equipment receives the data packet sent from the terminal side, the PDU in the data packet can be analyzed, if the check information in the PDU of the RLC layer of the data packet is valid, the access network equipment deletes the data packet corresponding to the data packet, and if the check information in the PDU of the RLC layer in the data packet is invalid, the corresponding data packet is sent again.
Optionally, in the embodiment of the present application, a retransmission mechanism of the RLC layer is utilized, and in a PING data packet sent to the access network device, a PDU of the RLC layer includes invalid check information, or does not include check information, so that after the access network device receives the PING data packet, because the check information carried by the PING data packet is invalid or does not carry check information, a retransmission mechanism of the RLC layer is triggered during the check of the RLC layer, an RRC connection between the terminal and the access network device is maintained, and the terminal is in a connected state.
Optionally, if the PING data packet sending request carries a predetermined time interval, the baseband chip sends a PING data packet to the access network device at a predetermined time interval.

Optionally, if the PING data packet sending request carries sending time, the baseband chip sends a PING data packet to the access network device within the sending time.

Optionally, if the PING data packet sending request carries a predetermined time interval and a sending time, the baseband chip sends a PING data packet to the access network device at intervals of the predetermined time interval within the sending time.
Illustratively, the terminal can carry a preset time interval and sending time in the PING data packet sending request through the application processor, the baseband chip sends PING data packets to the access network device at intervals of the preset time interval in the sending time according to the preset time interval and the sending time carried in the PING data packet sending request, and the energy consumption of the terminal is reduced on the basis of reducing communication delay by continuously sending PING data packets to keep RRC connection in the sending time.
To sum up, in the embodiment of the present application, when the application processor terminal detects that the application program running in the terminal has the low delay attribute, the baseband chip is notified to generate a PING data packet in the RLC layer and send the PING data packet to the access network device to maintain the RRC connection between the terminal and the access network device, thereby solving the problem that longer time is consumed for reestablishing the RRC connection, which results in a larger service delay, reducing the communication delay between the terminal and the access network device, and improving the working efficiency of the application program with the low delay attribute.
Further, in the embodiment of the present application, in the PING data packet generated by the RLC layer, the PDU of the RLC layer includes invalid check information, or does not include check information, so that the access network device triggers a retransmission mechanism of the RLC layer when the RLC layer checks after receiving the PING data packet, maintains RRC connection between the terminal and the access network device, and keeps the terminal in a connected state.
Further, in the embodiment of the application, the preset time interval is carried in the PING data packet sending request, and the baseband chip sends PING data packets to the access network device at intervals of the preset time interval according to the preset time interval carried in the PING data packet sending request, so that the continuity of the PING data packets is maintained and the RRC connection between the access network devices is reduced.

Further, in the embodiment of the application, the application processor carries a preset time interval and sending time in the PING data packet sending request, the baseband chip sends PING data packets to the access network device at intervals of the preset time interval in the sending time according to the preset time interval and the sending time carried in the PING data packet sending request, and the energy consumption of the terminal is reduced on the basis of maintaining the RRC connection by continuously sending the PING data packets in the sending time to reduce the communication delay.
Referring to fig. 4, a flowchart of a method for communication acceleration according to an exemplary embodiment of the present application is shown, where as shown, the method is applied in the mobile communication system shown in fig. 1, and the method includes:
The application processor acquires first picture information and/or first character string information of a first data packet transmitted in an application program when the application program running in the monitoring terminal.
Optionally, the application processor may obtain the character string information from the first picture information through a preset image processing algorithm.
For example, in the instant messaging application, different users send a dialog message through respective terminals, where the dialog message may be character string information containing only text, or may be static or dynamic picture information, or may be information containing both a picture and text. When a user sends a conversation message data packet through a terminal, an application processor acquires first picture information and/or first character string information in the conversation message data packet.
In step 402, the application processor detects whether the first picture information and/or the first character string information contains a preset feature.
For example, the picture information and/or the character string information carried by the data packet with the low-latency attribute generally has characteristics, for example, when a user publishes a state in a social friend circle of the social software, the text of the state includes "like" or the picture published by the state includes "click to open", and the terminal may pre-store the characteristics of the picture information and/or the character string information of the data packet with the low-latency attribute as preset characteristics.
When monitoring that a running application program sends a first data packet, the application processor detects whether character and/or picture information in the first data packet contains preset characteristics.
In step 403, if the first picture information and/or the first character string information includes a preset feature, the application processor determines that the first data packet has a low latency attribute.
If the first picture information and/or the first character string information included in the first data packet include the preset characteristics, it may be determined that the first data packet is a data packet with a low latency attribute. Wherein the predetermined characteristic is
Step 404, if the application processor determines that the first data packet has the low-delay attribute, determining that the application program has the low-delay attribute, and sending a PING data packet sending request to the baseband chip, where the PING data packet sending request carries a predetermined time interval and sending time.
Since the first data packet is a data packet with a low latency attribute, the application program transmitting the first data packet is an application program with a low latency attribute.
And when the application processor determines that the application program has the low-delay attribute, sending a PING data packet sending request to the baseband chip, wherein the PING data packet sending request carries a preset time interval and sending time.
And step 405, the baseband chip generates a PING data packet in the RLC layer according to the PING data packet sending request.
And the baseband chip generates a PING data packet in the RLC layer according to the PING data packet sending request, wherein the PING data packet comprises a PDU (protocol data Unit) of the RLC layer, and the PDU comprises invalid checking information or does not comprise the checking information.
And step 406, the baseband chip sends PING data packets to the access network device at preset time intervals within the sending time.
And the baseband chip sends the PING data packet to the access network equipment at intervals of preset time according to the preset time interval and the sending time carried in the PING data packet sending request. And when the duration of sending the PING data packet reaches the sending time, the baseband chip stops sending the PING data packet to the access network equipment.
Step 407, after the access network device determines that the data packet sent by the terminal is not received within the preset timeout period, the access network device sends an RRC connection release signaling to the terminal.
When the access network equipment does not receive the data packet sent by the terminal within the preset timeout duration, the access network equipment releases the RRC connection with the terminal, wherein the preset timeout duration is the duration specified in the communication protocol.
In step 408, the baseband chip switches the RRC connected state from the connected state to the idle state.
And the terminal switches the state of the RRC connection from the connection state to the idle state according to the RRC connection release signaling sent by the access network equipment.
To sum up, in the embodiment of the present application, when the application processor terminal detects that the application program running in the terminal has the low delay attribute, the baseband chip is notified to generate a PING data packet in the RLC layer and send the PING data packet to the access network device to maintain the RRC connection between the terminal and the access network device, thereby solving the problem that longer time is consumed for reestablishing the RRC connection, which results in a larger service delay, reducing the communication delay between the terminal and the access network device, and improving the working efficiency of the application program with the low delay attribute.
Further, in the embodiment of the application, by acquiring a first data packet transmitted by an application program running in the terminal, whether first picture information and/or first character string information in the first data packet contain preset features is detected to determine whether the application program has a low delay attribute, so that the accuracy of the terminal in determining whether the application program has the low delay attribute is improved.
Further, in the embodiment of the present application, in the PING data packet generated by the RLC layer, the PDU of the RLC layer includes invalid check information, or does not include check information, so that the access network device triggers a retransmission mechanism of the RLC layer when the RLC layer checks after receiving the PING data packet, maintains RRC connection between the terminal and the access network device, and keeps the terminal in a connected state.
Further, in the embodiment of the application, the application processor carries a preset time interval and sending time in the PING data packet sending request, the baseband chip sends PING data packets to the access network device at intervals of the preset time interval in the sending time according to the preset time interval and the sending time carried in the PING data packet sending request, and the energy consumption of the terminal is reduced on the basis of maintaining the RRC connection by continuously sending the PING data packets in the sending time to reduce the communication delay.
The application processor does not need to detect the data packet transmitted in the application program every time to judge whether the application program has the low delay attribute, the terminal can establish a low delay application program set for the application program with the low delay attribute determined by the application processor, and when the application processor monitors the application program running in the terminal, whether the application program has the low delay attribute can be determined by detecting whether the running application program is in the low delay application program set, so that the operation amount of the terminal is reduced, and the working efficiency of the terminal is improved. Determining whether an application has a low latency attribute by querying a set of low latency applications may be accomplished by the embodiment of fig. 4.
Referring to fig. 5, a flowchart of a method for communication acceleration according to an exemplary embodiment of the present application is shown, where as shown, the method is applied in the mobile communication system shown in fig. 1, and the method includes:
The application processor acquires a first identifier transmitted in an application program running in the terminal when monitoring the application program running in the terminal.

Optionally, the low-latency application program set may be constructed by: the application processor acquires a second data packet transmitted in a reference application program operated before the application program currently operated by the terminal; detecting whether the second data packet has a low latency attribute; if the second data packet has the low time delay attribute, acquiring a second identifier corresponding to the application reference application program; storing the second identifier in the set of low latency applications.
Optionally, the application processor may determine whether the second data packet has the low latency attribute through steps 301 to 303 in the embodiment of fig. 3.
If the first identifier exists in the set of low-latency applications, the application processor determines that the application has a low-latency attribute, step 503.

And 505, the baseband chip generates a PING data packet in the RLC layer according to the PING data packet sending request.
And the baseband chip generates a PING data packet in the RLC layer according to the PING data packet sending request, wherein the PING data packet comprises a PDU (protocol data Unit) of the RLC layer, and the PDU comprises invalid checking information or does not comprise the checking information.
Step 506, the baseband chip sends PING data packets to the access network device at predetermined time intervals within the sending time.
And the baseband chip sends the PING data packet to the access network equipment at intervals of preset time according to the preset time interval and the sending time carried in the PING data packet sending request. And when the duration of sending the PING data packet reaches the sending time, the baseband chip stops sending the PING data packet to the access network equipment.
Step 507, after the access network device determines that the data packet sent by the terminal is not received within the preset timeout period, the access network device sends an RRC connection release signaling to the terminal.
When the access network equipment does not receive the data packet sent by the terminal within the preset timeout duration, the access network equipment releases the RRC connection with the terminal, wherein the preset timeout duration is the duration specified in the communication protocol.
