At present, software such as an operating system and the like is installed and upgraded by a terminal manufacturer before the terminal equipment leaves a factory. Terminal manufacturers often adopt a wired transmission mode to upgrade software of terminal equipment, and the method specifically comprises the following steps: the terminal equipment is connected with the server through the data line to acquire the upgrade package from the server, wherein equipment such as a clamp, a cabinet and the like is required to be used for connection and fixation, the communication link is complex, the communication problems are more, the operation is complex, and the line body occupies a large area. In addition, the wired transmission may have hard contact with the terminal device, for example, the USB port of the terminal device is plugged and unplugged, which easily causes three injuries to the appearance of the terminal device.

In view of this, the embodiment of the application provides a software upgrading method, which automatically triggers a terminal to access a designated path through a wireless network to obtain an upgrading software package through a connection mode of NFC and WIFI, and downloads a software version into a batch of terminals for upgrading through wireless transmission.

According to the method, on one hand, the data transmission capacity of the wireless network can be utilized to replace an original wired transmission mode, and because the USB port is not plugged in and pulled out in the whole process, the risk of abnormal interruption possibly occurring in the transmission process of the data line is avoided, a large amount of computer resources and data lines are not required to be occupied, and the resource consumption and quality risk are reduced; hardware cabinet resources of the production line, clamps and operation working hours of the production line can be saved, so that the effect of saving manufacturing cost is achieved. On the other hand, because the appointed path is accessed through the wireless network, the operation of system upgrading which is carried out by accessing the computer through the data line is avoided, the operation steps are reduced, the operation convenience is improved, the downloading speed is improved, the quality yield of the terminal equipment is improved, and the reliability is improved.

In order to better understand a software upgrading method and related devices provided in the present application, a network architecture to which the embodiments of the present application are applied is described below.

Referring to fig. 1, fig. 1 is a schematic diagram of a network architecture of a communication system according to an embodiment of the present application. As shown in fig. 1, the network architecture may include a terminal device 100 and a server 200.

Wherein, the server 200 is configured to provide an upgrade package to the terminal device 100; the terminal device 100 is configured to receive an upgrade package from the server 200 to upgrade software.

Alternatively, the terminal device 100 may be one terminal device, or may include a plurality of terminal devices (see fig. 2 for details); server 200 (also referred to as a server) may be a device; a server farm may also be provided, such as one that includes an industrial personal computer and a version server (see fig. 2 for details).

Referring to fig. 2, fig. 2 is a schematic diagram of a network architecture of another communication system according to an embodiment of the present application.

As shown in fig. 2, the network architecture may include an industrial personal computer, a version server, a first router, and a plurality of terminal devices. The version server is used for providing an upgrade package for the industrial personal computer; the industrial personal computer is used for distributing the upgrade package to a plurality of terminal devices; the first router is a router connected with the terminal equipment, and the terminal equipment is communicated with the server through the first router. Then, the terminal device may receive the upgrade package from the version server through the router, and further upgrade the software based on the upgrade package.

Optionally, the network architecture may further include a carrier, where the carrier is configured to carry an NFC tag, and the NFC tag is configured to trigger the terminal device to connect to the router and execute a software upgrade procedure.

The terminal device 100 may be a User Equipment (UE), for example, an electronic device such as a mobile phone, a tablet computer, a notebook computer, a desktop computer, a smart television, a wearable device (e.g., a smart watch), a vehicle-mounted device, a smart home device (e.g., a smart speaker), an augmented reality (augmented reality, AR)/Virtual Reality (VR) device, an ultra-mobile personal computer (ultra-mobile personal computer, UMPC), a netbook, a personal digital assistant (personaldigital assistant, PDA), and the like. Exemplary embodiments of the terminal device 100 include, but are not limited to, portable electronic devices with iOS, android, harmony, windows, linux, or other operating systems mounted. The terminal device 100 may also be other portable electronic devices such as a Laptop computer (Laptop) or the like. It should also be appreciated that in other embodiments, the terminal device 100 described above may be a desktop computer or the like instead of a portable electronic device.

The software upgrading method provided by the embodiment of the application is exemplified by the following scenario of operating system upgrading of batch terminal devices in a production environment.

Next, a software upgrading method provided in the embodiment of the present application is described through fig. 3. The functions performed by the terminal device in this embodiment may also be performed by a module (e.g., a chip) in the terminal device, and the functions performed by the server in this application may also be performed by a module (e.g., a chip) in the server.

The method comprises the following partial or total steps:

s301: when a plurality of terminal devices are located on a carrier, first information contained in NFC labels on the carrier is acquired through NFC, and the first information comprises router information of a first router and information indicating to start a first application.

The first information is used for indicating to acquire an upgrade package of the operating system, the NFC label is arranged on a carrier, and the carrier is used for carrying a plurality of devices.

Fig. 4A illustrates a carrier for carrying a terminal device, the carrier comprising a carrier part and NFC tags, fig. 4A illustrates that the carrier comprises 4 NFC tags and 4 positions where the terminal device can be placed. For example, the carrier may be configured to carry 4 folding machines, where when the 4 folding machines are located on the carrier, the first information included in the NFC tag on the carrier is acquired through NFC, and the first information includes router information of the first router and information indicating that the first application is started. It should be understood that the carrier is only an example, and should not be construed as limiting the application, and in other embodiments of the application, the size of the location where the terminal device is placed in the carrier may be changed according to a specific model of the terminal device, which is not limited in the application.

S302: the plurality of terminal devices respectively respond to the information indicating the starting of the first application and start the first application.

Fig. 4B illustrates a schematic diagram of launching a first application. As shown in fig. 4B, the terminal device may acquire NFC card information (i.e., the first information included in the NFC tag); judging NFC information characteristics based on NFC card information, wherein the NFC card information can comprise NFC tag information; if the terminal equipment judges that the NFC tag information is the production tag, the terminal equipment can judge whether to pull up the first application; if the production tag is a tag indicating an upgrade of the operating system (i.e. the information indicating that the first application is started), the terminal device may pull up (i.e. start) the first application; if the production tag is a generated tag of other production requirements, the terminal device may execute a tag forwarding query, for example, display an interface as shown in fig. 4C, where the interface includes a popup 401, and the popup is used to query whether to launch an application corresponding to the tag. Illustratively, this first application may be referred to as the esasist test platform.

It should be appreciated that the NFC tag on the carrier may be one of the production tags described above, in a custom tag format.

S303: the plurality of terminal devices are respectively connected with the first router through the first application based on the router information of the first router, and the plurality of terminal devices are respectively communicated with the server through the first router.

The router information of the first router is identification information of the first router, such as service set identification (Service Set Identifier, ssid) ssid.

In some embodiments, after the first application is started, the router information of the first router may be obtained, and the WiFi application is invoked to connect to the first router.

In an exemplary production environment before the terminal equipment leaves the factory, the automatic connection of the wifi production environment can be realized through the steps. Specifically, the method comprises the following steps: (1) the carrier is equipped with an NFC tag containing router information of the first router and information indicating that the first application is started. (2) After the terminal equipment is placed on the carrier, triggering and acquiring corresponding information through NFC, and automatically starting APK (namely the first application) to connect with WiFi. (3) The terminal device automatically downloads the software version (i.e. the upgrade package) through the WiFi connection and completes the upgrade.

It can be appreciated that, when the NFC tag is sensed, a popup window (as shown in fig. 4C) is displayed at the present time, and the embodiment of the present application may automatically start the first application to implement connection with WiFi and software upgrade, without displaying the popup window to wait for confirmation of the user.

S304: and the plurality of terminal devices respectively send first requests to the server through the first router, wherein the first requests are used for requesting upgrade packages of the operating system.

Accordingly, the server receives a plurality of first requests from a plurality of terminal devices.

The upgrade package of the operating system is used for upgrading the operating system of the terminal equipment.

Alternatively, the first request may include an identification of the terminal device, such as a Serial Number (SN) and an IP address.

S305: and the plurality of terminal devices respectively establish Transmission Control Protocol (TCP) connection with the server.

In some embodiments, the server may establish a TCP connection with the terminal device after receiving the first request from the terminal device.

The embodiment of the application does not limit the specific implementation of establishing the TCP connection.

S306: the server multicasts N groups of data to a plurality of terminal devices through a user datagram protocol UDP, wherein an upgrade package of an operating system comprises N groups of data, and N is an integer larger than 1.

In some embodiments, the server receives the first requests from the plurality of terminal devices in a preset time period, and then the server may group the upgrade packages in packets to obtain N groups of data; further, the N groups of data are multicast to a plurality of terminal devices. In an exemplary embodiment, the server receives a first request from the first terminal at a first time, and a preset period of time is set between the first time and a second time, so that the server may determine that a terminal device that sends the first request to the server between the first time and the second time is the plurality of terminal devices, that is, the server multicasts N groups of data to the server between the first time and the second time.

In some embodiments, the first router may aggregate the multi-frame data frames in each of the N sets of data to obtain multi-frame aggregate data frames corresponding to each set of data; after receiving the N groups of data from the server, the first router may send a multi-frame aggregate data frame corresponding to each group of data to the terminal device. It should be appreciated that in the practical application scenario, UDP has a problem of low transmission rate, because the broadcast frames are not aggregated, and each TX frame needs to be re-subjected to clear channel assessment (ClearChannelAssessment, CCA) CCA, which is inefficient in use of the air interface. The embodiment of the application can reach the transmission rate of 40MB/s by modifying the protocol stack, using aggregation during UDP transmission and adjusting the aggregation degree and the density (density) of the aggregated MAC protocol data units (A-Medium Access Control (MAC) protocol data unit, A-MPDU). The method can reduce the time of data transmission and improve the efficiency of data transmission.

Wherein, the data frame in each group of data may be an MPDU (may be referred to as a subframe), and each component frame in the MPDU has an 802.11 frame header. MPDUs therefore add overhead to each component frame. In the embodiment of the application, by starting the AMPDU through the broadcast frame, a plurality of subframes (i.e. multi-frame data frames in each group of data) can be aggregated to obtain an a-MPDU subframe. Each a-MPDU sub-frame is composed of MPDU deltamite and MPDU entities. For an a-MPDU, the remaining subframes, except the last subframe, have 0-3 bytes of padding field, making the subframe length an integer multiple of 4 bytes. The aggregated data frame reduces the PLCP Preamble and PLCP Header required for transmitting each 802.11 message, thereby improving the throughput of the system.

Alternatively, the first router may be connected to a plurality of terminal devices, and send an upgrade packet to the plurality of terminal devices. According to the embodiment of the application, the multicast does not need to use a shielding box, and the AP (namely the first router) can save AP and space resources by one-to-many.

S307: after multicasting each group of data, the server respectively sends handshake request messages corresponding to the group of data to a plurality of terminal devices through TCP connection; the handshake request message is used for requesting the receiving result of the group of data.

In one implementation, after sending a set of data, the server may send handshake request messages corresponding to the set of data to a plurality of terminal devices through TCP connection respectively; the handshake request message is used for requesting the receiving result of the group of data.

S308: after receiving the handshake request message of each group of data, the plurality of terminal devices respectively send handshake response messages to the server through TCP connection, wherein the handshake response messages comprise the receiving results of the group of data, and the receiving results of the group of data are used for indicating successful or failed receiving.

In one implementation, after receiving a handshake request message of each group of data, the terminal device checks whether the group of data has been received, and if the group of data has been received, sends a receiving result for indicating successful reception to the server; and if the group of data is not received, sending a receiving result for indicating the receiving failure to the server.

In another implementation, after receiving the handshake request message of each group of data, the terminal device checks whether the group of data has been received, and if the group of data has been received, sends a receiving result for indicating successful reception to the server; if the group of data is not received, waiting for preset time, and if the group of data is not received after the preset time, sending a receiving result for indicating the receiving failure to a server; and if the group of data is received after the preset time, sending a receiving result for indicating successful receiving to the server. The method can save transmission resources in case of slow data transmission caused by network delay.

S309: the server determines the reception condition of each group of data based on the handshake response message of each group of data among the N groups of data from the plurality of terminal devices.

In some embodiments, the server maintains receipt of a set of data after receiving a handshake response message for the set of data.

Alternatively, the reception situation of each set of data may include an identification of the terminal device that did not successfully receive the set of data.

The receiving condition of the group of data may be a handshake request message of the group of data from all terminal devices, or may be a handshake response message of only terminal devices that have not successfully received the group of data; but also the identity of the terminal device that did not successfully receive the set of data.

Optionally, if handshake response messages of a certain group of data from multiple terminal devices all indicate successful reception, the server may record that the receiving situation of the group of data is all successful. For example, the group of data is marked by a preset identifier, where the preset identifier is used to indicate that the group of data is received completely successfully.

Optionally, assuming that after the terminal device sends a handshake response message indicating that a certain group of data is received failed to the server, the terminal device receives the group of data before N groups of data are not received, the terminal device may send a handshake response message indicating that the group of data is received successfully to the server; further, the server may update the reception of the set of data.

S310: the server multicasts part or all of the N groups of data based on the receiving condition of each group of data.

In some embodiments, after multicasting N sets of data in turn, the server may perform second multicast on the terminal device that does not receive the data based on the receiving situation of the N sets of data. In the method, the server does not retransmit immediately when the terminal equipment does not receive the data, so that the influence of the fact that the individual terminal equipment does not receive a certain group of data on the software upgrading of a plurality of terminal equipment can be avoided.

The server performs the server on the upgrade package to group the upgrade package in a sub-package manner to obtain N groups of data; after all terminal devices are connected with a server, data distribution is carried out through UDP; all terminal equipment and a server synchronously establish TCP connection, and handshake is carried out on both sides after each group of data is sent; packet loss is generated in the distribution process and retransmission is not performed immediately, and the server can record packet loss information and information of corresponding terminal equipment; after the N groups of data transmission are completed, the terminal equipment which receives the data completely exits from the data reception; and then the server plays back the data corresponding to the recorded packet loss information circularly, and each unfinished terminal device (i.e. the terminal device which does not receive the N groups of data) exits the data receiving after the corresponding packet loss is acquired.

Optionally, if handshake response messages of a certain group of data from the plurality of terminal devices all indicate that the reception is successful, the second multicast group server may not multicast the group of data.

The specific procedure of the second wheel multicast may be referred to as the procedure of steps S306 to S310.

In one implementation, after performing the second multicast, if there are still terminal devices that do not receive part of the data, the server may perform the third multicast.

Optionally, if after m-wheel multicast, if the terminal device still does not receive part of the data, the server and/or the terminal device may display the receiving condition of the terminal device. Where m is an integer greater than 2, e.g., m is 3. In the method, a worker can check the receiving condition of the terminal equipment to check the terminal equipment and the like, and the problem that the whole software upgrading time is too long due to continuous data transmission caused by the fact that part of the terminal equipment fails and the like can be avoided.

S311: and the plurality of terminal devices upgrade the operating system based on the received upgrade packages respectively.

In some embodiments, the terminal device upgrades the operating system based on the N sets of data after receiving the N sets of data.

The following exemplary process of steps S306 to S308 is described with reference to fig. 4D. Assuming that the plurality of terminals includes a first terminal, fig. 4D schematically illustrates data transmission between the first terminal and the server. FIG. 4D illustrates three of the N sets of Data, data1, data2, and Data3, respectively; and exemplarily shows a handshake request message Reguest1 corresponding to Data1, and a handshake response message ACK1 corresponding to Data 1; handshake request message Reguest2 corresponding to Data2, handshake response message ACK2 corresponding to Data 2; data3 corresponds to a handshake request message Reguest3, and Data3 corresponds to a handshake response message ACK3.

As shown in fig. 4D, the server may transmit Data1 to the first terminal through UDP, and transmit eguest1 to the first terminal through a TCP connection after transmitting Data 1; after receiving the provision 1, the first terminal may send ACK1 to the server, where ACK1 is used to indicate whether the first terminal receives Data1. Further, upon receiving the ACK1, the server may transmit Data2 to the first terminal via UDP, and transmit eguest2 to the first terminal via a TCP connection after transmitting Data 2; after receiving the provision 2, the first terminal may send an ACK2 to the server, where the ACK2 is used to indicate whether the first terminal receives Data2. Further, upon receiving the ACK1, the server may transmit Data3 to the first terminal via UDP, and transmit eguest3 to the first terminal via a TCP connection after transmitting Data 3; after receiving the provision 3, the first terminal may send an ACK3 to the server, where the ACK3 is used to indicate whether the first terminal receives Data3.

Optionally, if ACK1 is used to indicate that the first terminal does not receive Data1, the server may store the ACK1; or record that the first terminal did not receive Data1. After multicasting N groups of Data, the server may send Data1 to the first terminal based on the stored ACK1 or information that the first terminal does not receive Data1. It can be understood that if the server retransmits the first terminal immediately when receiving the data of a certain group, the server will affect other terminals to receive the data of the next group, so that the method can avoid affecting the data reception of other terminal devices in the plurality of terminal devices by retransmitting the terminal which does not receive the data of the certain group after multicasting the data of the N groups, which is beneficial to improving the overall data transmission rate.

The embodiment of the application can solve the problem that the wireless transmission scene cannot be one-to-many between the AP and the terminal equipment in a multicast mode. Since the UDP protocol is an ideal protocol for distributing information, but the UDP protocol is connectionless and unreliable, it is not currently used in this scenario. In the method, the multicast protocol is combined with the TCP and UDP, the data to be transmitted are grouped into packets, then broadcast and distributed by the UDP protocol, and meanwhile, one-to-one TCP connection is established between the AP and each terminal device. And carrying out ACK check and retransmission interaction on the distributed data packets by utilizing a TCP protocol, thereby realizing reliable broadcast transmission.
