Referring to fig. 1, a schematic diagram of an implementation environment provided by an embodiment of the present application is shown. The implementation environment may be a mobile communication system, which may be a Long Term Evolution (LTE) system or a 5th generation mobile communication technology (5G) system, also called New Radio (NR) system. The mobile communication system may include: a terminal 11 and an access network device 12.
The terminal 11 may include various handheld devices, vehicle-mounted devices, wearable devices, computing devices or other processing devices connected to a wireless modem with wireless communication functions, as well as various forms of User Equipment (UE), Mobile Stations (MS), terminal equipment (terminal device), and so on.
The terminal 11 includes an AP and a baseband chip. An application processor is a processor in the terminal for running an operating system and application programs. Such as: monitoring the running condition of the application program, monitoring the data packet of the application program and the like. The Baseband chip, also referred to as a Baseband chip Processor (BP), is a Processor for communicating with access network devices. Such as: and providing network request, call and short message service. The application processor and the baseband chip communicate with each other through a shared memory (shared memory). Alternatively, the application processor and the baseband chip may be integrated into a single processor.
The terminal 11 and the access network device 12 establish a wireless connection through a wireless air interface. Optionally, the wireless air interface is a wireless air interface based on an LTE standard, for example, the wireless air interface is a Uu interface; or, the wireless air interface is based on a 5G standard; alternatively, the wireless air interface may be a wireless air interface based on a 5G next generation mobile communication network technology standard.
Optionally, as shown in fig. 1, the implementation environment further includes a server 13. The server 13 is configured to provide low-latency services to the terminal 11, such as a red packet snatching service, a shopping second killing service, and the like. The server 13 may be one server, a server cluster composed of a plurality of servers, or a cloud computing service center. Alternatively, the server 13 is a network-side server that establishes a communication connection with the access network device 12 through the core network.
Fig. 2 is a flowchart of a method for managing a wireless connection according to an embodiment of the present application, which may be applied to the AP of the terminal in the embodiment shown in fig. 1. The method may include several steps as follows.
Step 201, establishing a wireless connection with an access network device.
In this embodiment, the terminal may previously establish a wireless connection with the access network device. For example, in the LTE system, a Radio connection between a terminal and an access network device is called a Radio Resource Control (RRC) connection. In other communication systems in subsequent evolution, the connection may still be referred to as an RRC connection or may be referred to by other names, which is not limited in this application.
When the wireless connection is in a connected state, the terminal can directly communicate with the service server. The wireless connection can also be in an idle state, when the wireless connection is in the idle state, the terminal cannot communicate with the service server, if the terminal has a communication requirement, the wireless connection needs to be restored from the idle state to a connection state, and the process needs to consume a certain amount of time, so that the time delay when the terminal communicates with the service server is increased.
The low-delay service refers to a service with a delay requirement smaller than a preset threshold, where the preset threshold may be set according to an actual requirement, and the preset threshold is not limited in this embodiment of the application, and exemplarily, the preset threshold is 20 ms. For example, low latency traffic refers to a red envelope snatching traffic in social applications; as another example, low latency traffic refers to shopping-second-kill traffic in a shopping-like application.
In some embodiments of the present application, step 202 comprises the sub-steps of:
step 202a, detecting whether a specified application program exists in the terminal and is in a running state;
step 202b, if the specified application program in the terminal is in the running state, determining that the terminal has the service requirement of the low-delay service.
In this embodiment of the application, the designated application refers to an application that has a service requirement of a low-latency service, for example, the designated application refers to a social application corresponding to the red packet robbing application, and a shopping application corresponding to a shopping second killing service.
Optionally, the terminal stores a designated application program list, where the designated application program list includes an identifier of an application program with a service requirement of a low-latency service, and when an application program is started subsequently, the AP directly searches whether the identifier of the started application program exists in the designated application program list, and if the designated application program list includes the identifier of the started application program, it is determined that the terminal has the service requirement of the low-latency service; and if the appointed application program list does not comprise the identification of the started application program, determining that the terminal does not have the service requirement of the low-delay service.
When the radio connection is not in the connected state, that is, when the radio connection is in the idle state, the radio connection needs to be switched from the idle state to the connected state.
The ACK packet is returned by the receiving device to the sending device after receiving the data, and it usually carries data indicating that the reception is error-free. The target device may be any device that establishes a wireless connection with the access network device. For example, the target device is a server, or a server cluster composed of a plurality of servers.
In order to avoid the situation, in the embodiment of the present application, the terminal is always in the connected state by sending an ACK packet to the target device. And if the terminal does not have the service requirement of the low-delay service, ending the whole process.
In some embodiments of the present application, the ACK packet sent by the AP to the target device also carries error checking information. The ACK packet usually carries check information, for the sending device to check the receiving device, where the check information is, for example, a checksum (checksum). In the embodiment of the application, since the check information carried in the ACK packet is erroneous, the ACK packet may be discarded by the routing device, the access network device, and the like in the ACK packet transmission process, so that the target device does not need to check the ACK packet sent by the AP on the premise that the wireless connection is maintained in the connected state, thereby saving the processing resource of the target device.
Fig. 3 is a block diagram relating to the embodiment shown in fig. 2. In this embodiment of the present application, when detecting that a terminal has a service requirement of a low latency service, an AP sends a notification message to a Framework layer (Framework) in the terminal to notify the Framework layer that the terminal has the service requirement of the low latency service, and then an Internet Protocol (IP) Protocol stack of the Framework layer in the AP sends an ACK packet to a server.
To sum up, in the method provided in this embodiment, when there is a service requirement for a low latency service in a terminal, an ACK packet is sent to a target device on a network side through a wireless connection established between the terminal and an access network device, in this process, the wireless connection between the terminal and the access network device is always maintained in a connected state, and subsequently, when the terminal needs to communicate with a service server on the network side, the terminal can directly communicate with the service server without first switching the terminal from an idle state to a connected state, thereby reducing a communication latency between the terminal and the service server.
In addition, the ACK data packet carries wrong checking information, so that the ACK data packet is discarded in the transmission process, and the follow-up target equipment does not need to check the ACK data packet, so that the processing resource of the target equipment is saved.
Fig. 4 is a flow chart of a method of managing a wireless connection as provided by another embodiment of the present application. The method may comprise the steps of:
In some embodiments of the present application, step 402 includes the following substeps:
step 402a, detecting whether a specified application program exists in the terminal and is in a running state;
step 402b, if the specified application program in the terminal is in the running state, detecting whether the specified application program has a specified operation event;
step 402c, if the specified operation event exists in the specified application program, determining that the terminal has the service requirement of the low-delay service.
The specified operation event may be an event in which the terminal communicates with the service server through a specified application program. For example, specifying an operational event refers to the terminal receiving a red envelope sent by the business server through the social application.
The terminal also stores a designated operation event list, the designated operation event list comprises an identification of an operation event with a service requirement of the low-delay service and an identification of an application program corresponding to the operation event, when a certain application program is started subsequently and the operation event occurs in the application program, the AP detects whether the designated event operation list comprises the identification of the operation event, and if the designated event operation list comprises the identification of the operation event, the terminal is determined to have the service requirement of the low-delay service; and if not, determining that the terminal does not have the service requirement of the low-delay service.
In the embodiment of the application, after detecting that the designated application program is in the running state, the AP further detects whether a designated operation event occurs in the designated running program, so that the terminal is prevented from sending the ACK packet too frequently, and processing resources of the terminal are saved.
The DRX state includes a sleep state and an active state. In a wireless communication system, there is a DRX mechanism under which a terminal periodically switches between a sleep state and an active state. When the terminal is in a sleep state, the terminal does not monitor a subframe in a Physical Downlink Control Channel (PDCCH); when the terminal is in an active state, the terminal can monitor the subframes in the PDCCH all the time. If the terminal needs to send an ACK packet to the target device when being in the sleep state, the terminal needs to be switched from the sleep state to the active state first, which results in higher power consumption of the terminal. Therefore, in the embodiment of the present application, before sending the ACK packet to the target device through the wireless connection, the DRX state of the terminal is acquired.
If the terminal is in the sleep state, the following step 404 is executed; if the terminal is in the active state, the following step 405 is performed.
And step 404, when the terminal is in the first active state after the sleep state, sending an ACK packet to the target device through the wireless connection, so that the terminal maintains the connection state.
If the terminal is in the sleep state, the AP sends an ACK data packet to the target equipment through wireless connection when the terminal is in a first activation state after the sleep state, so that the terminal is prevented from being switched from the sleep state to the activation state and then sending the ACK data packet.
In one example, sending the ACK packet to the target device over the wireless connection is specifically implemented as: and sending the ACK data packet to the target equipment once through wireless connection at intervals of a first time according to the interval indication information.
The interval indication information is used for indicating that the time interval between two consecutive times of sending the ACK data packets is a first duration. The first duration may be actually set according to a time required for the terminal to switch from the connected state to the idle state, for example, the first duration is less than a time required for the terminal to switch from the connected state to the idle state, and a difference between the first duration and the time required for the terminal to switch from the connected state to the idle state is less than a preset threshold, where the preset threshold may be set according to a requirement, and the embodiment of the present application is not limited thereto. For example, the time required for the terminal to switch from the connected state to the idle state is 5 seconds, and the first duration is 4 seconds. The first duration may be actually set by the AP according to a time required for the terminal to switch from the connected state to the idle state. In this example, the AP sends an ACK packet to the target device through the wireless connection every first time interval, so that the ACK packet is sent as little as possible on the premise that the terminal remains connected, thereby saving processing resources of the terminal.
In another example, sending the ACK packet to the target device over the wireless connection is specifically implemented as: and sending the ACK data packet to the target equipment through wireless connection within the second time length according to the time length indication information.
In order to avoid the above situation, it is necessary to limit the number of times of sending the ACK packets, in this embodiment, by setting the sending duration of sending the ACK packets to be 100 times, and thus limiting the number of times of sending the ACK packets, it is necessary to actually set the time interval between two consecutive times of sending the ACK packets, for example, the maximum sending number of times of sending the ACK packets is 100 times, and the time interval between two consecutive times of sending the ACK packets is 3 seconds, and then the sending time is 100 × 3 — 300 seconds.
In yet another example, the ACK packet is sent to the target device over the wireless connection every first duration for the second duration based on the interval indication information and the duration indication information.
For example, the maximum transmission times of the ACK packets is 100 times, and the first duration is 4 seconds, so that the transmission duration is 100 × 4-400 seconds.
Step 405, sending an ACK packet to the target device over the wireless connection.
To sum up, in the method provided in this embodiment, when there is a service requirement for a low latency service in a terminal, an ACK packet is sent to a target device on a network side through a wireless connection established between the terminal and an access network device, in this process, the wireless connection between the terminal and the access network device is always maintained in a connected state, and subsequently, when the terminal needs to communicate with a service server on the network side, the terminal can directly communicate with the service server without first switching the terminal from an idle state to a connected state, thereby reducing a communication latency between the terminal and the service server.
In addition, the DRX state of the terminal is acquired before the ACK data packet is sent, when the DRX state of the terminal is in the sleep state, the ACK data packet is sent to the target equipment through the wireless connection when the terminal is in the first active state after the sleep state, and the ACK data packet is prevented from being sent after the terminal is switched from the sleep state to the active state.
In addition, the time interval between two times of continuous sending of the ACK data packets is set, so that the sending times of the ACK data packets are reduced as much as possible on the premise of maintaining the connection state of the terminal, and the processing resources of the terminal are saved; in addition, the sending duration of the ACK data packets is set, so that the condition that the access network equipment switches the wireless connection from the connection state to the idle state on the premise that all the received ACK data packets fail to be checked is avoided.
