Description

Technical Field

[0001] This disclosure relates to the field of communications, and more particularly to a network switching method, apparatus, mobile terminal, readable storage medium, and chip. Background Technology

[0002] In related technologies, network switching in mobile terminal devices typically occurs suddenly while the source network is still transmitting data, causing lag. This is because data packets being encapsulated in the source network's format may be lost, and then re-encapsulated in the target network before being transmitted. This process causes delays in the transmission and reception of some data, which is the main cause of network lag. Therefore, there is an urgent need for a network switching method to avoid lag during network switching. Summary of the Invention

[0003] To overcome the problems existing in related technologies, this disclosure provides a network switching method, apparatus, mobile terminal, readable storage medium, and chip.

[0004] According to a first aspect of the present disclosure, a network switching method is provided, applied to a mobile terminal, comprising: upon receiving a network switching instruction, encapsulating unsent data from data to be sent in a source network format to obtain a source network data packet, and encapsulating the unsent data in a target network format to obtain a target network data packet; sending the source network data packet and the target network data packet to a server; receiving first response data returned by the server based on the source network data packet, and second response data returned by the server based on the target network data packet; and controlling the mobile terminal to switch from the source network to the target network when the first response data and the second response data satisfy network switching conditions.

[0005] Optionally, the network switching condition is that the similarity between the first response data and the second response data is greater than or equal to a preset similarity.

[0006] Optionally, the method further includes: receiving a plurality of first sub-data packets and / or a plurality of second sub-data packets, until the similarity between the response data obtained based on the plurality of first sub-data packets and the response data obtained based on the plurality of second sub-data packets is greater than or equal to the preset similarity, and determining that the first response data is consistent with the second response data; wherein the first sub-data packet is the response data corresponding to the source network data packet, and the second sub-data packet is the response data corresponding to the target network data packet.

[0007] Optionally, after controlling the mobile terminal to switch from the source network to the target network, the process includes: stopping the encapsulation of data in the source network format, encapsulating data in the target network format, and sending the encapsulated data to the server through the target network.

[0008] Optionally, the method further includes: during the time period between receiving the network switching instruction and switching to the target network, reporting the data in the data packet encapsulated and transmitted in the source network format to the application layer for use.

[0009] According to a second aspect of the present disclosure, a network switching apparatus is provided, applied to a mobile terminal, comprising: a processing module configured to, upon receiving a network switching instruction, encapsulate unsent data from data to be sent in a source network format to obtain a source network data packet, and encapsulate the unsent data in a target network format to obtain a target network data packet; a sending module configured to send the source network data packet and the target network data packet to a server; a receiving module configured to receive first response data returned by the server based on the source network data packet, and second response data returned by the server based on the target network data packet; and a switching module configured to control the mobile terminal to switch from the source network to the target network when the first response data and the second response data satisfy network switching conditions.

[0010] According to a third aspect of the present disclosure, a mobile terminal is provided, comprising: a processor; and a memory for storing processor-executable instructions; wherein the processor is configured to execute the executable instructions to implement the steps of the aforementioned network switching method.

[0011] According to a fourth aspect of the present disclosure, a computer-readable storage medium is provided that stores computer program instructions thereon, which, when executed by a processor, implement the steps of the network switching method provided in the first aspect of the present disclosure.

[0012] According to a fifth aspect of the present disclosure, a chip is provided, including a processor and an interface; the processor is configured to read instructions to perform the steps of the aforementioned network switching method.

[0013] The technical solutions provided by the embodiments of this disclosure can include the following beneficial effects: After receiving a network switching command, the mobile terminal encapsulates the unsent data in the data to be sent in the source network format to obtain a source network data packet, and encapsulates the unsent data in the target network format to obtain a target network data packet. The source network data packet and the target network data packet are sent to the server, and the server returns a first response data based on the source network data packet and a second response data based on the target network data packet. If the first response data and the second response data meet the network switching conditions, the mobile terminal is controlled to switch from the source network to the target network. After receiving the network switching command, the unsent portion of the data to be sent is encapsulated in the source network format and the target network format respectively to obtain data packets in two network formats. The two network format data packets are sent out to receive response data in two network formats. If the response data in the two network formats meet the predetermined network switching conditions, the mobile terminal is controlled to switch from the source network to the target network. This avoids packet loss of the source network data packet and re-encapsulation of the target network data packet during the network switching process, thereby avoiding network latency caused by re-encapsulation of data and effectively preventing network lag.

[0020] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0021] It is understood that in this disclosure, "multiple" refers to two or more, and other quantifiers are similar. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, and B alone. The character " / " generally indicates that the preceding and following related objects are in an "or" relationship. The singular forms "a," "the," and "the" are also intended to include the plural forms unless the context clearly indicates otherwise.

[0022] It is further understood that the terms "first," "second," etc., are used to describe various types of information, but this information should not be limited to these terms. These terms are only used to distinguish information of the same type from one another and do not indicate a specific order or degree of importance. In fact, the expressions "first," "second," etc., are completely interchangeable. For example, without departing from the scope of this disclosure, first response data can also be referred to as second response data, and similarly, second response data can also be referred to as first response data.

[0023] It is further understood that although operations are described in a specific order in the accompanying drawings in the embodiments of this disclosure, this should not be construed as requiring these operations to be performed in the specific order or serial order shown, or requiring all of the shown operations to be performed to obtain the desired result. In certain environments, multitasking and parallel processing may be advantageous.

[0024] It should be noted that all actions involving the acquisition of signals, information, or data in this disclosure are carried out in compliance with the relevant data protection laws and policies of the country where the location is situated, and with authorization from the owner of the relevant device.

[0025] Typically, the network before a mobile terminal device switches networks is the source network, and the network after the switch is the target network. While the data packets from the source network (encapsulated in the source network format) and the data packets from the target network (encapsulated in the target network format) are identical in their data portions, their encapsulation formats differ significantly. When a mobile terminal switches networks, data packets already sent from the mobile terminal may be retransmitted after processing in the cloud. At the moment of the switch, due to the differences between the source and target network data packets, packets being encapsulated in the source network format may be lost. The lost data is then recapsulated in the target network format. This recapsulation causes network lag, a phenomenon particularly noticeable in real-time applications. For example, in games with high real-time requirements, switching networks during gameplay can cause significant network fluctuations, leading to noticeable lag.

[0026] For the reasons mentioned above, this disclosure provides a method that can significantly reduce the probability of data retransmission and data loss during network switching, thereby effectively reducing network lag.

[0027] Figure 1 A flowchart illustrating a network handover method as an exemplary embodiment of this disclosure is shown below. Figure 1 As shown, this network switching method is used in mobile terminal devices such as mobile phones and tablets, and includes the following steps.

[0028] In step S101, after receiving the network switching instruction, the unsent data in the data to be sent is encapsulated in the source network format to obtain the source network data packet, and the unsent data is encapsulated in the target network format to obtain the target network data packet.

[0029] In computer networks, data is typically transmitted in multiple packets. One part of the data has already been transmitted to the destination address or is in the transmission path, while another part is being encapsulated. This data is the data to be sent, and the part being encapsulated is the unsent data within the data to be sent.

[0030] The network switching command instructs the mobile terminal to switch from a source network to a target network. The network before the network switch occurs is the source network, and the network after the switch is the target network. For example, when the mobile terminal switches from a 4G network to a WiFi network, 4G is the source network and WiFi is the target network. Similarly, when the mobile terminal switches from a first WiFi network to a second WiFi network, the first WiFi network is the source network and the second WiFi network is the target network. The network switching command can be triggered by user operation of the mobile terminal or automatically triggered by the mobile terminal detecting that the current network signal strength is lower than a first threshold. The first threshold can be determined based on empirical data or other feasible methods; this disclosure does not impose any restrictions on this.

[0031] Source network data packets are obtained by the mobile terminal encapsulating the unsent portion of the data to be sent in the source network format, and destination network data packets are obtained by the mobile terminal encapsulating the unsent portion of the data to be sent in the destination network format. For example, when a mobile terminal switches from a 4G network to a WiFi network and encapsulates and transmits data packets using the IP protocol, before receiving the network switching instruction, the mobile terminal encapsulates the unsent portion of the data to be sent in the 4G network format based on the IP protocol to obtain a 4G network data packet; after switching networks, the mobile terminal encapsulates the unsent portion of the data to be sent in the WiFi network format based on the IP protocol to obtain a WiFi network data packet.

[0032] Upon receiving a network switching command, the system encapsulates the unsent portion of the data to be sent in the source network format to obtain a source network data packet, and encapsulates the unsent portion in the target network format to obtain a target network data packet. For example, if the mobile terminal is currently connected to a 4G network and is encapsulating and transmitting data packets in the 4G network format, and a portion of the data to be sent has already been sent out while the remaining portion is still being encapsulated, and a network switching command is received at this time, such as a command to switch to a WiFi network, the system does not immediately switch networks upon receiving the command. Instead, it encapsulates the unsent portion of the data to be sent in the 4G network format to obtain a 4G network data packet, and encapsulates the unsent portion of the data to be sent in the WiFi network format to obtain a WiFi network data packet. The 4G network data packet is the source network data packet, and the WiFi network data packet is the target network data packet.

[0033] In step S102, the source network data packet and the target network data packet are sent to the server.

[0034] The source and destination network data packets obtained in the above steps are sent to the server, that is, the 4G network data packets and WiFi network data packets are sent to the server. It should be noted that the source and destination network data packets here will be sent to the same server. For example, when a mobile terminal is running a game application and receives a network switching command, regardless of whether the mobile terminal encapsulates and transmits data packets using the source network or the destination network, the backend server that interacts with it is the server of that game application.

[0035] In step S103, the first response data of the source network data packet and the second response data of the target network data packet are received from the server.

[0036] The first response data is the server's response data to the source network data packet, and the second response data is the server's response data to the target network data packet. The source network data packet or the target network data packet is equivalent to the request data of the mobile terminal, which is used to request the required data from the server. The server responds with data packets in the source network format and the target network format, respectively. Therefore, the first response data contains the server's response data to the source network data packet, and the second response data contains the server's response data to the target network data packet.

[0037] In step S104, if the first response data and the second response data meet the network switching conditions, the mobile terminal is controlled to switch from the source network to the target network.

[0038] If the first response data and the second response data meet the network switching conditions, control the mobile terminal to switch from the source network to the target network.

[0039] In one implementation, the network switching condition is that the similarity between the first response data and the second response data is greater than or equal to a preset similarity. If the similarity between the first response data and the second response data is greater than or equal to the preset similarity, then the first response data and the second response data can be considered identical. As mentioned above, the source network data packet and the target network data packet differ in their encapsulation format, but their data portions are identical. Figure 2 As shown, Figure 2 This is a schematic diagram illustrating an exemplary embodiment of the present disclosure of an IP packet. The encapsulation format includes version, header length, differentiated services, total length, identifier, flags, source address, destination address, and data, wherein the version is the version field of the transport protocol, the header length is the header length of the packet, differentiated services are the priority and application type of the IP packet, and the data is the payload data. Figure 2 For encapsulation formats not specifically described in this document, please refer to the data packet format of the IP protocol in computer networks; they will not be elaborated upon here.

[0040] based on Figure 2 It is known that the mobile terminal encapsulates the unsent portion of the data to be sent in both the source network format and the target network format. Ideally, after a certain period, the response data for these two network format data packets should be identical. Therefore, when the first and second response data are identical, and the mobile terminal is switched from the source network to the target network, the mobile terminal will not immediately stop encapsulating in the source network format upon receiving the network switching command, discarding the data packets being encapsulated in the source network format, and instead recapsulate the lost data in the target network format. This avoids network congestion caused by data recapsulation. It should be noted that the aforementioned timeframe needs to be determined based on the current network congestion and data packet size, etc., and will not be elaborated upon here.

[0041] In one implementation, the server divides the response data into multiple sub-data packets for transmission. That is, the first and second response data are divided into multiple sub-data packets for transmission, corresponding to the packet concept in computer networks. The server divides the first response data into multiple first sub-data packets and the second response data into multiple second sub-data packets. However, due to uncertainties such as network congestion and packet size, the arrival times of all the first and second sub-data packets at the mobile terminal may differ. Therefore, in practical applications, it is necessary to save the sub-data packets that arrive at the mobile terminal first, and then wait for a period of time for subsequent sub-data packets to arrive at the mobile terminal until no more first or second sub-data packets arrive. At this point, all the first sub-data packets are parsed, and the parsed data is concatenated to obtain the first response data. All the second sub-data packets are then parsed and the data is... The first response data is obtained by concatenating all the data obtained from the analysis. Then, the first response data and the second response data are compared. If the first response data and the second response data are consistent, it means that the target network has been able to replace the source network for packet encapsulation and transmission. At this time, the mobile terminal can be controlled to switch from the source network to the target network without causing packet loss or lag. If the first response data and the second response data are inconsistent, it means that there is packet loss in the source network or the target network has not completely encapsulated the remaining part of the data to be sent. Then, wait to receive the next sub-data packet of the two different network formats to be sent, and repeat the above parsing and concatenation steps to compare the consistency of the response data of the two network formats.

[0042] It should be noted that the network handover method provided in this disclosure, during the time period between receiving the network handover command and handover to the target network, uses data packets encapsulated and transmitted in the source network format. Although data packets encapsulated and transmitted in the target network format can also be received during this period, the data transmitted in the target network format is not used. That is, the data transmitted in the target network format is only used at the transport layer and is not reported to the application layer. Both the transport layer and the application layer are layers in the five-layer protocol of computer networks. After controlling the mobile terminal to handover from the source network to the target network, the encapsulation and transmission of data packets in the source network format is stopped, and the encapsulation and transmission of data packets in the target network format are performed. At this time, the data encapsulated and transmitted in the target network format is reported to the application layer for use.

[0043] In summary, the network switching method provided in this disclosure includes: after receiving a network switching command, the mobile terminal encapsulates the unsent data in the data to be sent in the source network format to obtain a source network data packet, and encapsulates the unsent data in the target network format to obtain a target network data packet; sends the source network data packet and the target network data packet to a server; receives first response data returned by the server based on the source network data packet and second response data returned based on the target network data packet; and controls the mobile terminal to switch from the source network to the target network if the first response data and the second response data meet the network switching conditions. Upon receiving the network switching command, the mobile terminal encapsulates the unsent portion of the data to be sent in the source network format and the target network format respectively to obtain data packets in two network formats; sends the data packets in both network formats to receive response data in both network formats; and controls the mobile terminal to switch from the source network to the target network if the response data in both network formats meet the predetermined network switching conditions. This avoids packet loss of the source network data packet and re-encapsulation of the target network data packet during the network switching process, thereby avoiding network latency caused by re-encapsulation and effectively preventing network lag.
