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.
In order that the aspects shown in the embodiments of the present application can be easily understood, several terms appearing in the embodiments of the present application will be explained below.
Low-delay information: the data packet used for indicating that the application program contains the instant service is a data packet with a data processing speed higher than a preset speed threshold. That is, the data packet of the instant service has a low delay attribute, and is a data packet whose service delay is lower than the preset delay threshold. The preset speed threshold and the preset time delay threshold may be constant values preset by developers in the user equipment, or values set by the user in a user-defined manner in the using process. For example, the preset delay threshold may be 20ms, 40ms, or 80 ms.
Optionally, the application with low latency information has a data packet of the instant service, and the data packet of the instant service contains data that needs to be processed by the user instantly in real time. For example, the data packet of the instant service is virtual resource data using the virtual commodity packet as a carrier. The virtual goods package is a carrier of virtual resources which can be donated in a resource transfer mode between at least two user accounts of the same application program, and the at least two user accounts can be respectively operated in two different user terminals. The virtual goods package can comprise: cash, points, coupons, vouchers, redemption tickets, virtual coins, electronic pets, electronic titles, gaming equipment, membership identities, and the like. The present embodiment does not limit the resources in the virtual package.
Optionally, in this embodiment of the present application, the virtual article package may be implemented as an electronic Red package (english: Red Packet) or a virtual Red package.
It should be noted that some terms referred to in the present embodiment may refer to relevant specifications in the 3GPP protocol. For example, RRC _ CONNECTED, RRC _ IDLE, ACK, etc., which are not described in this embodiment again.
In the related art, if the ue is in a connected state and no data packet is sent to the access network device within a preset timeout period, the access network device may release the RRC connection with the ue. At this time, the user equipment transitions from the connected state to the idle state. Thereafter, when the ue needs to transmit uplink data, the ue needs to send a request to the access network device, so as to reestablish an RRC connection with the access network device, and after the RRC connection is reestablished, the ue is changed from an idle state to a connected state.
In the connection process, after the RRC connection between the user equipment and the access network equipment is released, the time required for the user equipment to reestablish the RRC connection is long, resulting in a long time delay for data transmitted through the RRC connection. In view of this problem, embodiments of the present application provide a method for reducing communication latency, which is described below with reference to exemplary embodiments.
Fig. 1 is a schematic structural diagram of a mobile communication system according to an embodiment of the present application. The mobile communication system may be an LTE system or a fifth generation mobile communication technology (5G), which is also called a New Radio (NR) system. In this embodiment, the mobile communication system may include: user equipment 110, access network equipment 120, and target server 130.
The user equipment 110 runs a target application program, and the target application program has low-latency information, that is, an application program supporting a low-latency service, and is used for processing a data packet of an instant service.
Optionally, the target application is an application supporting an instant service, with low latency information. For example, the target application is an application supporting a red packet robbing function or an application supporting a praise function. Alternatively, the target application is a travel-type application having an order grabbing function, and the like. The embodiment of the present application does not limit the specific type of the target application.

The user equipment 110 includes an Application Processor (AP) and a baseband chip (modem).
An application processor is a processor in a user device that runs an operating system and application programs. For example, the running state of the application program is monitored, and the packet transmission condition of the application program is monitored.
The Baseband chip is also called a Baseband chip Processor (BP), which is a Processor for communicating with the access network device 120. The baseband chip may be used to perform various communication services, such as sending short messages, making voice calls, and establishing network communication requests.
Optionally, the application processor and the baseband chip may communicate with each other by way of a shared memory (english memory).
Alternatively, the application processor and the baseband chip may be integrated into a single processor.
User equipment 110 establishes a wireless connection with access network device 120 over a wireless air interface. Optionally, the wireless air interface is based on an LTE standard; or the wireless air interface is a wireless air interface based on a 5G standard, for example, the wireless air interface is NR; alternatively, the radio air interface may be a radio air interface based on a subsequent next generation mobile communication network technology standard of 5G.
Access network device 120 may be a base station that may coordinate attribute management for the air interface. For example, the base station may be an evolved Node B (eNB) in LTE, or the base station may also be a base station adopting a centralized distributed architecture in a 5G system.
The target server 130 is a third-party server disposed in the cloud, and the target server 130 is configured to receive the ACK packet sent by the user equipment 110 through the access network device 120.
Optionally, the target 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.
For example, taking the mobile communication system as an LTE system as an example, please refer to fig. 2, which is a protocol layer configuration diagram of a radio bearer. The Access network device 120 and the user device 110 are respectively configured with an IP layer, a Packet Data Convergence Protocol (PDCP) layer, a radio link layer Control Protocol (RLC) layer, a Media Access Control (MAC) layer, and a Physical layer (PHY) layer of a radio bearer, respectively, in which when a piece of signaling or Data is transmitted from the Access network device 120 to the user device 110 through the radio bearer, after the Access network device 120 sequentially passes through the PDCP layer, the RLC layer, the MAC layer, and the PHY layer, a radio frequency unit of the Access network device 120 sends the signaling or the Data to the user device 110, and the signaling or the Data is received by the radio frequency unit of the user device 110 and sequentially passes through the PHY layer, the MAC layer, the PLC layer, and the PDCP layer of the user device 110 for processing. Accordingly, when a piece of signaling or data is transmitted from the user equipment 110 to the access network equipment 120 through the radio bearer, the processing order of the protocol layers is reverse to the above order.
Fig. 3 is a flowchart of a method for reducing a communication delay according to an embodiment of the present application, where the method may be applied to the user equipment, and is applied to a process of the user equipment performing processing in a PDCP layer, where the method includes:
step 301, when detecting that an application program running in user equipment has low delay information, an application processor sends a request for sending an acknowledgement character ACK data packet to a baseband chip; low latency information refers to information that is sensitive to communication latency.
In the embodiment of the application, an application processor in the user equipment detects whether an application program running in the user equipment has low-delay information, and when the application program running in the user equipment has the low-delay information, the application processor sends a request for sending an acknowledgement character ACK packet to a baseband chip. Wherein the low latency information may be in the form of attribute data.
Alternatively, the low latency information may be information sensitive to communication latency. The low-delay information can exist in a plaintext form, and also can exist in an encrypted text form or a picture form.
Step 302, the baseband chip generates an ACK data packet in a packet data convergence protocol PDCP layer according to the ACK data packet request of the confirmation character.
In the embodiment of the application, a baseband chip in the user equipment may obtain the ACK packet request by sharing a memory. Then, the baseband chip generates an ACK packet in the PDCP layer according to the ACK packet request of the acknowledgement character.
Step 303, the baseband chip sends an ACK packet to the access network device, where the ACK packet is used to maintain the RRC connection between the user equipment and the access network device.
In the embodiment of the present application, a baseband chip in a user equipment sends an ACK packet to an access network device, where the ACK packet is used to maintain a radio resource control RRC connection between the user and the access network device.
Optionally, the ACK packet is generated at the PDCP layer. Therefore, the user equipment transmits the ACK packet to the access network equipment through the RLC layer, the MAC layer, and the PHY in sequence.
Accordingly, the access network device maintains the RRC connection with the user equipment after receiving the ACK packet.
To sum up, the embodiment of the application is applied to a user equipment including a baseband chip and an application processor, when the application processor detects that an application program running in the user equipment has low delay information, the application processor is controlled to send an ACK packet sending request to the baseband chip, the baseband chip generates an ACK packet in a PDCP layer according to the ACK packet request, and sends the ACK packet to an access network device, where the ACK packet is used to maintain RRC connection between the user equipment and the access network device. Due to the fact that the user equipment can generate the ACK data packet on the PDCP layer under the cooperation of the application processor and the baseband chip and send the ACK data packet to the access network equipment, RRC connection between the user equipment and the access network equipment is maintained, an application program with low delay information running in the user equipment can communicate with the server through the access network equipment quickly, communication delay between the user equipment and the server is reduced, and availability of the application program with the low delay information in the user equipment is improved.
Fig. 4 is a flowchart of another method for reducing communication latency according to an embodiment of the present application, where the method may be applied to the user equipment, and is applied to a process of the user equipment performing processing in a PDCP layer, where the method includes:
in step 401, the application processor detects whether a first data packet of the application program has low latency information.
Optionally, the application processor may obtain the first picture information and/or the first character information in the first data packet. The application processor detects whether the first picture information and/or the first character information contain preset characteristics, wherein the preset characteristics are characteristics contained in a data packet of an application program with low time delay information. If the first picture information and/or the first character information contain preset characteristics, the application processor determines that the first data packet has low-delay information.
The first data packet may be a data packet transmitted or received by an application program running in the user equipment. The first picture information and/or the first character information may include a predetermined characteristic, and the predetermined characteristic identifies a characteristic included in a packet of the application having the low latency information. For example, if the application processor needs to ensure that the data packet for transmitting and receiving the electronic red packet can be processed with a communication quality with a low delay, a preset feature library may be preset in the user equipment, and features in the data packet for transmitting and receiving the electronic red packet are stored in the preset feature library. When the application processor detects that the first picture information contains the preset features, or when the application processor detects that the first character information contains the preset features, or when the application processor detects that the first picture information contains the preset features and the first character information contains the corresponding preset features, the application processor determines that the first data packet contains low-delay information.
If the first data packet has low latency information, the application processor determines that the application program has low latency information, step 402.
Optionally, the application processor can determine whether the application program is a low-latency application program by performing steps 403 to 405, in addition to determining whether the first data packet has low-latency information by performing steps 401 and 402.
Correspondingly, when the first data packet does not have the low-delay information, the user equipment does not process the first data packet, and the process is ended.
At step 403, the application processor obtains a first identifier of the application program.
In an embodiment of the application, the application processor may obtain the first identifier of the application when the application is started. Alternatively, the first identifier may be an installation package name or a feature identification code of the application program.
Step 404, the application processor queries whether a first identifier exists in the low-latency application program set; the set of low latency applications is a set of identities of low latency applications pre-stored in the user equipment.
In the embodiment of the present application, a low-latency application set is preset in a user equipment, and the set stores an identifier of each low-latency application. For example, as shown in table one, the table one contains the identification of several low latency applications.
Watch 1

Identification A.apk B.apk C.apk D.apk
The user equipment may store table one in advance, and the application equipment queries whether the first identifier exists in table one.
Optionally, in an implementation manner, the application processor can further obtain a second data packet of the application program running before the application program; the application processor detects whether the second data packet has low-delay information, and if the second data packet has the low-delay information, the application processor acquires a second identifier corresponding to an application program operated before the application program; the application processor stores the second identification in a set of low latency applications.
Alternatively, the application processor may detect whether the second data packet has a low latency property by the following manner. In the scheme, the application processor acquires second picture information and/or second character information in a second data packet; the application processor detects whether the second picture information and/or the second character information contain preset characteristics, wherein the preset characteristics are characteristics contained in a data packet of an application program with low time delay information; if the second picture information and/or the second character information contains the preset characteristics, the application processor determines that the second data packet has low-delay information.
The second data packet may be a data packet transmitted or received by an application program running in the user equipment. The second picture information and/or the second character information may include a predetermined characteristic, where the predetermined characteristic identifies that the second packet is a characteristic included in a packet of an application having low latency information. For example, if the application processor needs to ensure that the data packet for transmitting and receiving the electronic red packet can be processed with a communication quality with a low delay, a preset feature library may be preset in the user equipment, and features in the data packet for transmitting and receiving the electronic red packet are stored in the preset feature library. When the application processor detects that the second picture information contains the preset features, or when the application processor detects that the second character information contains the preset features, or when the application processor detects that the second picture information contains the preset features and the second character information contains the corresponding preset features, the application processor determines that the second data packet contains the low-delay information.
In step 405, if the first identifier exists in the set of low-latency applications, the application processor determines that the application is a low-latency application.
In the embodiment of the application, when the first identifier exists in the preset low-latency application program set, the application processor determines the application program as the low-latency application program.
In contrast, when the first identifier does not exist in the low-latency application set, the process ends.
In step 406, the application processor sends an ACK packet transmission request to the baseband chip.
Step 407, the baseband chip generates an ACK packet in the packet data convergence protocol PDCP layer according to the ACK packet transmission request.
In the embodiment of the application, a baseband chip in the user equipment may obtain the ACK packet request by sharing a memory. Then, the baseband chip generates an ACK packet in the PDCP layer according to the ACK packet request of the acknowledgement character.
Optionally, the ACK packet includes a protocol data unit PDU, where the PDU includes invalid check information, or may also be referred to as error check information. Alternatively, in another possible implementation, the PDU does not contain the check information.
Optionally, the ACK packet sending request carries the first time period and/or the second time period. The first time period is a time interval between two consecutive transmission of the ACK data packet, and the second time period is a duration of time when the ACK data packet is transmitted.
Step 408, the baseband chip sends an ACK packet to the access network device, where the ACK packet is used to maintain the RRC connection between the user equipment and the access network device.
In one possible implementation manner, the baseband chip sends the ACK packet to the access network device every first time period.
In another possible implementation manner, the baseband chip sends the ACK packet to the access network device in the second time period.
In yet another possible implementation manner, the baseband chip sends the ACK packet to the access network device every other first time period within the second time period.
It should be noted that, in order to avoid maintaining the RRC connected state with high resource occupation between the user equipment and the access network equipment for a long time, an embodiment of the present application further provides a scheme for releasing the RRC connected state. In the scheme, when the duration of sending the ACK data packet reaches a second time period, the baseband chip stops sending the ACK data packet, and switches the RRC connection state from the connection state to the idle state according to the control of the access network device.
In summary, according to the method provided by the embodiment of the present application, the user equipment includes an application processor and a baseband chip; the application processor can detect whether a first data packet in an application program has low delay information or not, when the first data packet has the low delay information, the application program is determined to have the low delay information, then an ACK data packet sending request of a confirmation character is sent to the baseband chip, the baseband chip generates an ACK data packet according to the ACK data packet sending request, then the ACK data packet is sent to the access network equipment, and RRC connection between the user equipment and the access network equipment is maintained through the ACK data packet, so that the delay of data receiving and sending of the application program with the low delay information is reduced, and the sensitivity of the application program for receiving and sending data is improved.
In addition, in this embodiment, the application processor is enabled to obtain the first identifier of the application program, and query whether the first identifier exists in the low-latency application program set, determine that the application is called as the low-latency application program when the first identifier exists, and then send an ACK packet sending request of a confirmation character to the baseband chip, the baseband chip generates the ACK packet according to the ACK packet sending request, and then sends the ACK packet to the access network device, and the RRC connection between the user equipment and the access network device is maintained through the ACK packet, so that the identification degree of identifying the application that needs to maintain the RRC connection is improved, and the user equipment is enabled to automatically confirm the application that needs to maintain the RRC connection.
In addition, the embodiment can also detect first picture information and/or first character information in a first data packet in the application program, and determine whether the first data packet has low-delay information by determining whether the first data packet contains preset features. Therefore, the identification degree of whether the data packet of the application program needs to maintain the RRC connection is improved, and the communication delay of the data packet which needs to be sent or received with low time delay is reduced.
In addition, in this embodiment, when the duration of sending the ACK packet by the baseband chip reaches the second time period, the baseband chip stops sending the ACK packet, and switches the RRC connection state from the connection state to the idle state according to the control of the access network device, so that after ensuring that the application can complete receiving and sending of corresponding data with low delay, the RRC connection state with high resource occupancy between the user equipment and the access network device can be avoided for a long time.
