Background

With the rapid development of internet technology, Wi-Fi (Wireless Fidelity) as a technology for allowing an electronic device to be connected to a Wireless Local Area Network (WLAN) has become one of the most popular network access technologies due to its characteristics of high efficiency, convenience, and low cost, and has penetrated into various public places (e.g., restaurants, hotels, malls, etc.) and user homes. However, when using Wi-Fi networking, Wi-Fi signal weakening often occurs due to the user's movement (e.g., going into an elevator, going into and out of a company or home), resulting in a disruption of the network being connected, or the user may not be able to connect to the network or break the network connection being used when accessing unauthorized Wi-Fi. In the prior art, when a Wi-Fi signal is weak or access to unauthorized Wi-Fi occurs, the Wi-Fi connection can be manually switched to a mobile communication network (for example, a 4G network), however, due to the time delay characteristic of manual operation, the efficiency of network switching is reduced, and the network communication quality during network switching is affected.

By analyzing the current connection network signal state information, the receiving and sending channels of the service data are automatically converted according to the network signal state information, the network conversion efficiency is improved, and the network communication quality during network conversion is further improved.

The user terminal related to the embodiment of the invention can be a tablet computer, a smart phone, a palm computer, a Mobile Internet Device (MID) and other terminal devices with multiple network outlets.

The network optimization method provided by the embodiment of the invention will be described in detail below with reference to fig. 1 to 7.

Referring to fig. 2, a flow chart of a network optimization method according to an embodiment of the present invention is shown. As shown in fig. 2, the method of the embodiment of the present invention may include the following steps S101 to S103.

S101, under the condition that a first data channel of a user terminal is accessed to a wireless local area network currently, network signal state information of the wireless local area network is detected through the first data channel;

specifically, the network architecture for implementing network optimization according to the embodiment of the present invention may be as shown in fig. 1, where the user terminal 2 is connected to the Wireless Local Area network 3 and the cellular data network connection 4 through a first data channel and a second data channel, respectively, and it is understood that the Wireless Local Area Network (WLAN) may be a network that transmits data, voice and video signals over the air by using a Wireless technology, for example, a Wireless Fidelity (Wi-Fi) network. The first data channel may be a system default network data channel of the user terminal. The cellular data network may include a 2G, 3G, 4G, LTE (Long Term Evolution ) network, 5G, and other mobile data networks. In a specific implementation, the ue may determine that a network currently accessed by the first data channel or the second data channel is a wireless local area network or a cellular data network by detecting a source IP that sends data to the outside through the first data channel or the second data channel. For example, when the source IP of the service data currently sent by the first data channel is switched from the egress route IP corresponding to the cellular data network to the egress route IP of the Wi-Fi, it may be considered that the network currently accessed by the first data channel is switched from the cellular data network to the wireless local area network.

Under the condition that a first data channel of a user terminal is accessed to a wireless local area network currently, the user terminal can detect network signal state information of the wireless local area network through the first data channel. Optionally, the user terminal may send a data probe packet to an access device (e.g., a router) of the wireless local area network through the first data channel, and detect network signal state information of the wireless local area network according to a feedback message for the data probe packet returned by the access device of the wireless local area network, where the network signal state information may be any one or more of transmission delay, transmission delay variance, transmission rate, transmission bandwidth, throughput, delay-bandwidth product, and bandwidth utilization.

In an alternative embodiment, the first data Channel may be a Default Channel that is adopted by the user terminal by Default, and the first data Channel preferentially connects to a connectable wireless local area network when detecting that the connectable wireless local area network exists, and connects to the cellular data network when the connectable local area network does not exist. The second data Channel may be a Backup data Channel of the ue, and specifically may allocate a special Socket to the ue for always connecting to the cellular data network.

S102, when detecting that the network signal state information of the wireless local area network does not meet the first network signal quality condition, receiving and transmitting service data through a second data channel of the user terminal;

specifically, when the user terminal detects that the network signal state information of the wireless local area network does not satisfy the first network signal quality condition, the user terminal may send and receive service data through the second data channel of the user terminal, it may be understood that the first network signal quality condition may include at least one first quality condition threshold, and the first quality condition threshold may be a threshold for evaluating the quality of the network signal state information of the wireless local area network, and may be, for example, at least one of a transmission delay threshold, a transmission delay variance threshold, a rate threshold, a bandwidth threshold, a throughput threshold, a delay bandwidth product threshold, and a bandwidth utilization threshold. The service data may be various types of application data or multimedia data, such as audio, video, or text data.

In this embodiment of the present invention, when the state information value corresponding to the network signal state information of the wireless lan does not satisfy the first quality condition threshold (for example, when the network signal state information is required to be smaller than the first quality condition threshold, the obtained network signal state information is larger than the first quality condition threshold, and it may be considered that the network signal state information of the wireless lan does not satisfy the first network signal quality condition), that is, the current network signal state of the wireless lan is not good enough.

S103, when detecting that the network signal state information of the wireless local area network meets the first network signal quality condition, receiving and transmitting service data through the first data channel;

specifically, when the ue detects that the network signal status information of the wlan meets the first network signal quality condition (for example, when the network signal status information is required to be smaller than a first quality condition threshold, it is determined that the network signal status information is smaller than the first quality condition threshold), that is, when the network status of the wlan is better, the ue may receive and transmit the service data through the first data channel.

Referring to fig. 3, a schematic flow chart of another network optimization method according to an embodiment of the present invention is provided. As shown in fig. 3, the method of the embodiment of the present invention may include the following steps S201 to S205.

S201, under the condition that a first data channel of a user terminal is accessed to a wireless local area network currently, network signal state information of the wireless local area network is detected through the first data channel;

specifically, the network architecture for implementing network optimization according to the embodiment of the present invention may be as shown in fig. 1, where the user terminal 2 is connected to the wireless local area network 3 and the cellular data network 4 through a first data channel and a second data channel, respectively, and it is understood that the wireless local area network WLAN may be a network that transmits data, voice and video signals over the air by using wireless technology, for example, a Wi-Fi network. The first data channel may be a system default network data channel of the user terminal. The cellular data network may comprise a 2G, 3G, 4G, LTE network, 5G, etc. mobile data network.

It is understood that, before determining the data channel for transceiving the service data, the user terminal may detect a network type currently accessed by the first data channel, where the network type may include a wireless local area network and a cellular data network, and in a case that the first data channel is currently accessed by the wireless local area network, the step S201 is continuously performed.

Specifically, when it is detected that the first data channel of the user equipment is currently accessed to the wireless local area network, the network signal status information of the wireless local area network may be detected through the first data channel. It is understood that the network signal status information of the wireless local area network includes: any one or more of transmission delay, transmission delay variance, transmission rate, transmission bandwidth, throughput, delay-bandwidth product, and bandwidth utilization.

In an optional embodiment, the user terminal may send a data probe packet to an access device (e.g., a router) of the wireless local area network based on a preset time interval and using the first data channel, and determine network signal state information of the wireless local area network according to a received feedback message, where the feedback message is a message returned by the access device of the wireless local area network according to the data probe packet. It can be understood that the preset time interval may be any set smaller time interval, for example, 1s or 2s, the data probe packet may be any data packet, and after receiving the data probe packet, the access device of the wireless local area network may return a feedback message, that is, data reception confirmation information, to the user terminal, so as to inform the user terminal that the data probe packet is successfully sent.

Optionally, when the network signal status information of the wireless lan does not satisfy the first network signal quality condition, the step S202 may be executed, and when the network signal status information of the wireless lan satisfies the first network signal quality condition, the step S205 may be executed.

S202, when detecting that the network signal state information of the wireless local area network does not meet the first network signal quality condition, detecting the network signal state information of the cellular data network through the second data channel;

specifically, when the ue detects that the network signal status information of the wlan does not satisfy the first network signal quality condition, the ue may detect the network signal status information of the cellular data network through the second data channel. It is to be understood that the first network signal quality condition may include at least one first quality condition threshold, and the first quality condition threshold may be a threshold for evaluating the quality of the network signal status information of the wireless local area network, such as at least one of a transmission delay threshold, a transmission delay variance threshold, a rate threshold, a bandwidth threshold, a throughput threshold, a delay bandwidth product threshold, and a bandwidth utilization threshold, and the second data channel may access the cellular data network.

In an optional embodiment of the present invention, the user terminal may continuously send a Round-trip-delay (RTT) probe packet to the access device of the wireless lan through the first data Channel, i.e., the data Channel Default Channel, at an interval of 2s, to obtain a group of RTT discrete data, and specifically record 5 times of obtained RTT data, calculate a mean value and a variance of the 5 times of obtained RTT data, and finally determine whether the network signal status information of the wireless lan meets a transmission delay threshold and a transmission variance threshold in the first network signal quality condition by comparing a relationship between the mean value and the variance of the RTT data and a preset RTT value and variance, where the Round-trip delay may indicate that data is sent from a sending end until the sending end receives an acknowledgement from a receiving end (the receiving end immediately sends an acknowledgement after receiving the data), total experienced delay.

It can be understood that if the transmission delay of the wireless local area network reaches the transmission delay threshold or the transmission delay variance of the wireless local area network reaches (can be understood to be greater than or equal to) the transmission delay variance threshold, the network signal state information of the wireless local area network does not satisfy the first network signal quality condition. For example, if the transmission delay of the wireless local area network is 1s and the transmission delay threshold is 0.9s, the transmission delay reaches the transmission delay threshold, and it may be determined that the network signal state information of the wireless local area network does not satisfy the first network signal quality condition.

Optionally, when the user terminal detects that the transmission rate of the wireless local area network reaches (may be understood to be less than or equal to) a rate threshold, or the transmission bandwidth reaches (may be understood to be greater than or equal to) a credit threshold, or the delay bandwidth product reaches (may be understood to be greater than or equal to) a delay bandwidth product threshold, or the bandwidth utilization reaches (may be understood to be less than or equal to) a bandwidth utilization threshold, it may be determined that the network signal status information of the wireless local area network does not satisfy the first network signal quality condition. For example, the network signal status information of the wireless local area network may be determined not to satisfy the first network signal quality condition when any of the following conditions is satisfied: the transmission rate of the wireless local area network is 10MB/S, and the rate threshold value is 15 MB/S; or the transmission bandwidth of the wireless local area network is 200M, and the bandwidth threshold is 150M; or the time delay bandwidth product of the wireless local area network is 105bit/s, and the threshold value of the time delay bandwidth product is 100 bit/s; or the bandwidth utilization is 80% and the bandwidth utilization threshold is 85%.

It can be understood that, before the implementation of the embodiment of the present invention, the user terminal may determine the first quality condition threshold of the first network signal quality condition according to a data type of service data to be received and transmitted when a current network of a network to which the first data channel is currently accessed is a wireless local area network, where the service data may be various types of multimedia data, such as audio, video, or text data. Optionally, when the service data is video data or instant fighting game data, a better network signal is needed to realize stable transceiving of the video data, so that the determined first quality condition threshold is larger, and optionally, when the service data is text character data, non-instant fighting game data, or the like, the service data can be transceived without high network signal quality requirements, so that the determined first quality condition threshold is smaller. The first quality condition threshold of the first network signal quality condition may be determined according to the data type of the service data to be received and transmitted by presetting the first quality condition threshold corresponding to the different types of service data.

In this embodiment of the present invention, when the network signal status information of the wireless local area network needs to be smaller than the first quality condition threshold, but the detected network signal status is larger than the first quality condition threshold, it may be considered that the network signal status information of the wireless local area network does not satisfy the first network signal quality condition, that is, the current network signal status of the wireless local area network is not good enough. When the network signal state information of the wireless local area network does not meet the first network signal quality condition, the network signal state information of the cellular data network can be detected through the second data channel, and whether the service data can be transmitted and received through the second data channel is determined.

In an optional embodiment, the user terminal may send a data probe packet to the access device of the cellular data network by using the second data channel, and determine the network signal state information of the cellular data network according to the received feedback message, where the feedback message is a message returned by the access device of the cellular data network according to the data probe packet. It is understood that the network signal status information of the cellular data network comprises: any one or more of transmission delay, transmission delay variance, transmission rate, transmission bandwidth, throughput, and delay-bandwidth product.

S203, when detecting that the network signal state information of the cellular data network meets the second network signal quality condition, receiving and transmitting service data through a second data channel of the user terminal;

specifically, when the user terminal detects that the network signal state information of the cellular data network meets the second network signal quality condition, the service data may be received and transmitted through the second data channel of the user terminal. It is to be appreciated that the second network signal quality condition can include at least one second quality condition threshold comprising at least one of a transmission delay threshold, a transmission delay variance threshold, a rate threshold, a bandwidth threshold, a throughput threshold, and a delay bandwidth product threshold.

It can be understood that, before the embodiment of the present invention is executed, when the current network of the network to which the first data channel is currently accessed is a cellular data network, the user terminal may determine the second quality condition threshold of the second network signal quality condition according to the data type of the service data to be received and transmitted, and a specific determination method may refer to the process of determining the first instruction condition threshold in step S203, which is not described herein again.

It is to be understood that the network signal status information of the cellular data network satisfies the second network signal quality condition if the transmission delay of the cellular data network does not reach (can be understood as being less than or equal to) the transmission delay threshold. For example, if the transmission delay of the cellular data network is 0.5s and the transmission delay threshold is 1s, the transmission delay does not reach the transmission delay threshold and meets the low delay reachable condition, and it may be determined that the network signal state information of the cellular data network meets the second network signal quality condition.

In this embodiment of the present invention, when the network signal status information of the cellular data network is required to be greater than the second quality condition threshold, and the detected network signal status information is also greater than the second quality condition threshold, it may be considered that the network signal status information of the cellular data network satisfies the second network signal quality condition, that is, when the current network signal status of the cellular data network is better, the service data may be received and transmitted through the second data channel of the user terminal.

In an optional embodiment of the present invention, the user terminal may send an RTT detection packet through the second data Channel, that is, the Backup data Channel, determine whether the Backup data Channel is reachable with low latency based on the sent RTT detection packet, and if the Backup data Channel is reachable with low latency, determine that the network signal state information of the cellular data network satisfies a transmission latency threshold in the second network signal quality condition.

In the embodiment of the invention, under the condition that the network signal state information of the wireless local area network is determined not to meet the first network signal quality condition, when the network signal state information of the cellular data network is further determined to meet the second network signal quality condition, the service data is transmitted and received through the second data channel, and the reliability of network switching is improved.

S204, in the process of receiving and sending service data through a second data channel of the user terminal, detecting the network signal state information of the wireless local area network through the first data channel, and switching to receiving and sending the service data through the first data channel when detecting that the network signal state information of the wireless local area network meets the first network signal quality condition;

it is understood that, when it is detected that the network signal status information of the wireless local area network does not satisfy a first network signal quality condition and the network signal status information of the cellular data network satisfies a second network signal quality condition, the service data is transceived by using the second data channel of the user terminal, the network signal status information of the wireless local area network can be detected at any time through the first data channel during the process of transceiving the service data by using the second data channel, when it is detected that the network signal status information of the wireless local area network satisfies the first network signal quality condition, the transceiving of the service data can be switched to transceiving the service data through the first data channel, that is, when the network status of the wireless local area network is good, the transceiving of the service data can be switched from the second data channel to the first data channel, continuing to use the wireless local area network.

it can be understood that the ue may obtain the round trip transmission delay obtained by at least two detections, for example, the ue obtains the round trip transmission delay every 2s for 5 times, and then obtains the delay mean and the delay variance of the round trip transmission delay obtained for 5 times respectively. It is understood that the delay mean and the delay variance may represent network signal status information of the currently accessed wireless local area network.

Further, the ue may determine the delay mean as the network signal state information of the transmission delay in the network signal state information of the wlan, or may determine the delay variance as the network signal state information of the transmission delay variance in the network signal state information of the wlan.

It should be noted that, when the maximum transmission delay is smaller than the transmission delay threshold in the second quality condition threshold, it may be considered that the second data channel is satisfied with low delay.

Further, the ue may determine the maximum transmission delay as the network signal status information of the transmission delay in the network signal status information of the cellular data network.

In the embodiment of the invention, under the condition that a first data channel of a user terminal is accessed to a wireless local area network currently, network signal state information of the wireless local area network is detected through the first data channel, when the network signal state information of the wireless local area network is detected not to meet a first network signal quality condition, service data is transmitted and received through a second data channel of the user terminal, wherein the second data channel is accessed to a cellular data network, and when the network signal state information of the wireless local area network is detected to meet the first network signal quality condition, the service data is transmitted and received through the first data channel.

Referring to fig. 6, a schematic flow chart of another network optimization method according to an embodiment of the present invention is provided. As shown in fig. 6, the method of the embodiment of the present invention may include the following steps S501 to S503.

S501, under the condition that a first data channel of a user terminal is currently accessed to a cellular data network, detecting whether the network currently accessed to the first data channel is switched to a wireless local area network from the cellular data network;

It is understood that the user terminal may detect a network type currently accessed by the first data channel before determining the data channel for transceiving the traffic data, and the network type may include a wireless local area network and a cellular data network. Optionally, when the first data channel is currently accessed to the cellular data network, the user terminal may determine that the network to which the first data channel is currently accessed is the wireless local area network or the cellular data network by continuously monitoring a source IP that sends data to the first data channel. For example, when the source IP of the service data currently sent by the first data channel is switched from the egress route IP corresponding to the cellular data network to the egress route IP of the Wi-Fi, it may be considered that the network currently accessed by the first data channel is switched from the cellular data network to the wireless local area network.

S502, when detecting that a first data channel of a user terminal is successfully accessed to a wireless local area network, receiving and transmitting service data through a second data channel of the user terminal;

specifically, when it is detected that a first data Channel of the user terminal successfully accesses the wireless local area network, the user terminal may adopt the first data Channel to receive and transmit the service data, optionally, before adopting the first data Channel to receive and transmit the service data, the user terminal may force the service data to be received and transmitted through a second data Channel, that is, a Backup data Channel, and simultaneously, the network signal state information of the wireless local area network is detected through the first data Channel.

S503, during the process of transceiving service data through the second data channel of the user equipment, detecting the network signal status information of the wireless local area network through the first data channel, and switching to transceiving service data through the first data channel when it is detected that the network signal status information of the wireless local area network meets the first network signal quality condition;

it can be understood that, when the user terminal forcibly uses the second data channel to receive and transmit the service data, the user terminal may detect network signal status information of the wireless local area network at any time through the first data channel, where the network signal status information of the wireless local area network includes: the user terminal may send a data probe packet to an access device (e.g., a router) of the wireless local area network through the first data channel, and detect network signal state information of the wireless local area network according to a feedback message for the data probe packet returned by the access device of the wireless local area network.

When detecting that the network signal state information of the wireless local area network meets the first network signal quality condition, the user terminal may switch to transceiving the service data through the first data channel, that is, when the network state of the wireless local area network is good, the user terminal may switch to transceiving the service data from using the second data channel to using the first data channel, and continue to use the wireless local area network.

In an optional embodiment of the present invention, the user terminal may continuously send an RTT (round trip delay) probe packet to the access device of the wireless lan through the first data Channel, that is, the data Channel Default Channel, at an interval of 2s, obtain a group of RTT discrete data, specifically record RTT data obtained 5 times, calculate a mean value and a variance of the RTT data obtained 5 times, and finally determine whether the network signal status information of the wireless lan meets a transmission delay threshold and a transmission delay variance threshold in the first network signal quality condition by comparing a relationship between the mean value and the variance of the RTT data and a preset RTT value and variance.

In the embodiment of the invention, when a wireless local area network is newly accessed, the newly accessed wireless local area network is not used for receiving and sending the service data, but the cellular data network is used for ensuring the continuation of the service data, and the wireless local area network is switched to the wireless local area network for receiving and sending the data under the condition of ensuring the good network quality of the wireless local area network, so that the interruption of receiving and sending of the service data caused by the wireless local area network which is actually unavailable or unstable is avoided.

The network optimization process according to the embodiment of the present invention will be described with reference to a specific example, where the first network signal quality condition for evaluating the first network signal state is a transmission delay threshold and a transmission delay variance threshold, and a specific implementation process is shown in fig. 7:

s601, setting a round trip delay threshold and a round trip delay variance threshold when a user terminal communicates with a wireless local area network access device;

the embodiment of the invention mainly relates to two network signal quality conditions for judging the network signal state information, namely a round trip delay threshold and a round trip delay variance threshold, and the required round trip delay threshold and the required round trip delay variance threshold can be preset according to the round trip delay and the delay variance under different network states in historical experience before network optimization is carried out. It can be understood that the round trip delay may represent a total time delay from when the transmitting end transmits data to when the transmitting end receives an acknowledgement from the receiving end (the receiving end transmits the acknowledgement immediately after receiving the data), and the delay variance may be a value obtained by calculating a variance of round trip delays for a plurality of times, which may reflect fluctuation of the round trip delay.

S602, initializing a port number of a forced binding cellular data network outlet as a standby data channel;

it can be understood that, in the network optimization method according to the embodiment of the present invention, a backup data channel needs to be set to provide a transceiving channel as service data when different network types are converted, where the backup data channel may be the second data channel in the foregoing method embodiment.

In an alternative embodiment, the port number Socket as the backup data channel may be named backup channel.

S603, judging the network outlet type of the default data channel;

it can be understood that, before determining the data channel for transceiving the service data, the user terminal needs to detect the network type currently accessed by the default data channel, where the default data channel may be the first data channel in the above method embodiment. The network types may include a wireless local area network and a cellular data network, and when the determination result in step S603 is that the current network outlet type is the wireless local area network, the operations in step S604 to step S607 may be correspondingly performed. When the judgment result of step S603 is that the current network outlet type is the cellular data network, the operations in step S611, step S612, and steps S609 to S610 may be correspondingly performed, wherein the two branches corresponding to step 603 may establish a connection through step S607 and step S608.

S604, detecting network signal state information of the wireless local area network based on the round trip delay threshold and the round trip delay variance threshold;

specifically, the ue may detect the network signal status information of the wlan through a default data channel and based on the round trip delay threshold and the round trip delay variance threshold, where a specific implementation process may include step S6041 to step S6043, and the detection process of the network signal status information in step S6041 to step S6043 may refer to relevant descriptions in step S202 in the foregoing method embodiment and is not described here again.

S6041, continuously sending RTT detection packets at an interval of 2S in a default data channel, obtaining a group of RTT discrete data, and recording the latest n-RTT data of 5 times;

s6042, calculating the mean and variance of the latest RTT data where n is 5 times;

s6043, judging whether the mean value of the discrete RTT data is larger than a round trip delay threshold or the variance is larger than a round trip delay variance threshold;

s605, using a cellular data channel to receive and transmit service data;

it can be understood that, when it is detected in step S604 that the network status information of the wireless local area network does not satisfy the first network signal quality condition (i.e. the above-mentioned round trip delay threshold and round trip delay variance threshold), the current network signal status of the wireless local area network may be considered to be poor, and the user terminal may use the cellular data channel to transceive the service data.

S606, detecting the network state of the cellular data network;

it can be understood that, when the cellular data channel is used to receive and transmit the service data, the user terminal may detect a network state of the cellular data network, that is, determine whether the cellular data channel satisfies the low latency reachability, and a specific determination process may refer to related description in step S203 and is not described herein again. It can be understood that, when the detection result of step S606 is that the network state of the cellular data network is better, the ue may perform step S607 to switch the default data channel to the cellular data channel for receiving and sending the service data, and when the detection result is that the network state of the cellular data network is not good enough, the ue may return to perform step S604 to continue to detect the network state of the wlan.

S607, switching the default data channel to the cellular data channel to receive and transmit the service data;

s608, detecting the network state of the wireless local area network through a default data channel;

it can be understood that, while the cellular data channel is used to receive and transmit service data, the network state of the wireless local area network may be detected through the default data channel, when it is detected that the network signal state information of the wireless local area network satisfies the first network signal quality condition, the network state of the wireless local area network may be considered to be better, the step S609 may be performed to switch the cellular data channel to the default data channel to receive and transmit service data, when it is detected that the network signal state information of the wireless local area network does not satisfy the first network signal quality condition, the network state of the wireless local area network may be considered to be poor, and the step S610 may be performed to detect that the network signal state information of the wireless local area network satisfies the first network signal quality condition, the network state of the wireless local area network may be considered to be better. In a specific implementation, the process of step S608 and the process of step S604 may include step S6081 to step S6083, and the detection process and the data channel switching condition may refer to the related description in step S202, which is not described herein again.

S609, switching the cellular data channel into a default data channel to receive and transmit service data;

s610, not using the default data channel, and forcibly using the standby data channel to receive and transmit the service data;

s611, continuously monitoring a source IP of the service data transmitted and received by the default data channel;

it can be understood that, in the case that it is determined in step S603 that the default data channel is currently accessed to the cellular data network, the user terminal may determine that the network to which the default data channel is currently accessed is the wireless local area network or the cellular data network by detecting a source IP of data sent outside through the default data channel, and specific implementation processes of step S611 and step S612 may refer to relevant descriptions in step S501, which is not described herein again.

S612, judging whether the source IP is switched to the exit route of the wireless local area network.

In the embodiment of the invention, under the condition that a first data channel of a user terminal is accessed to a wireless local area network currently, network signal state information of the wireless local area network is detected through the first data channel, when the network signal state information of the wireless local area network is detected not to meet a first network signal quality condition, service data is transmitted and received through a second data channel of the user terminal, wherein the second data channel is accessed to a cellular data network, and when the network signal state information of the wireless local area network is detected to meet the first network signal quality condition, the service data is transmitted and received through the first data channel. By analyzing the state information of the current connection network signal, the receiving and sending channels of the service data are automatically converted according to the state information of the network signal, the network conversion efficiency is improved, and the network communication quality during network conversion is further improved; under the condition that the network signal state information of the wireless local area network is determined not to meet the first network signal quality condition, and when the network signal state information of the cellular data network is further determined to meet the second network signal quality condition, service data is received and transmitted through a second data channel, so that the reliability of network conversion is improved; in the process of receiving and sending service data based on the second data channel, whether the wireless local area network reaches a better state is detected at any time, and excessive consumption of data flow is avoided when the signal state of the wireless local area network is better; when a wireless local area network is newly accessed, the newly accessed wireless local area network is not used for receiving and sending service data, but the cellular data network is used for ensuring the continuation of the service data, and the wireless local area network is switched to the wireless local area network for receiving and sending the data under the condition of ensuring the good network quality of the wireless local area network, so that the interruption of receiving and sending the service data caused by the fact that the access network is unavailable or unstable is avoided.

in a specific implementation, a network architecture for implementing network optimization according to an embodiment of the present invention may be as shown in fig. 1, where a user terminal 2 is connected to a wireless local area network 3 and a cellular data network 4 through a first data channel and a second data channel, respectively, and it is understood that the wireless local area network WLAN may be a network that transmits data, voice and video signals over the air by using wireless technology, for example, a Wi-Fi network. The first data channel may be a system default network data channel of the user terminal. The cellular data network may comprise a 2G, 3G, 4G, LTE network, 5G, etc. mobile data network.

It can be understood that, before determining the data channel for transceiving the service data, the user terminal 1 may detect a network type currently accessed by the first data channel, where the network type may include a wireless local area network and a cellular data network, and in a case that the first data channel is currently accessed by the wireless local area network, the process corresponding to the first information detecting unit 11 is continuously performed.

In a specific implementation, when it is detected that a first data channel of the user equipment is currently accessed to a wireless local area network, the first information detecting unit 11 may detect network signal status information of the wireless local area network through the first data channel. It is understood that the network signal status information of the wireless local area network includes: any one or more of transmission delay, transmission delay variance, transmission rate, transmission bandwidth, throughput, delay-bandwidth product, and bandwidth utilization.

In an optional embodiment, the first information detecting unit 11 may send a data probe packet to an access device (e.g., a router) of the wireless local area network based on a preset time interval and using the first data channel, and determine network signal status information of the wireless local area network according to a received feedback message, where the feedback message is a message returned by the access device of the wireless local area network according to the data probe packet. It can be understood that the preset time interval may be any set smaller time interval, for example, 1s or 2s, the data probe packet may be any data packet, and after receiving the data probe packet, the access device of the wireless local area network may return a feedback message, that is, data reception confirmation information, to the user terminal 1, so as to inform the user terminal 1 that the data probe packet is successfully sent.

Optionally, when the network signal status information of the wireless lan does not satisfy the first network signal quality condition, a process corresponding to the second information detecting unit 15 may be performed, and when the network signal status information of the wireless lan satisfies the first network signal quality condition, a process corresponding to the second channel switching unit 13 may be performed.

A second information detecting unit 15, configured to detect network signal status information of the cellular data network through the second data channel when detecting that the network signal status information of the wireless local area network does not satisfy the first network signal quality condition;

in a specific implementation, when the second information detecting unit 15 detects that the network signal status information of the wireless local area network does not satisfy the first network signal quality condition, the network signal status information of the cellular data network may be detected through the second data channel. It is to be understood that the first network signal quality condition may include at least one first quality condition threshold, and the first quality condition threshold may be a threshold for evaluating the quality of the network signal status information of the wireless local area network, such as at least one of a transmission delay threshold, a transmission delay variance threshold, a rate threshold, a bandwidth threshold, a throughput threshold, a delay bandwidth product threshold, and a bandwidth utilization threshold, and the second data channel may access the cellular data network.

In an optional embodiment of the present invention, the user terminal 1 may continuously send RTT detection packets to the access device of the wireless lan through the first data Channel, i.e., the data Channel Default Channel, at intervals of 2s, to obtain a group of RTT discrete data, and specifically record 5 times of obtained RTT data, calculate a mean value and a variance of the 5 times of obtained RTT data, and finally determine whether the network signal status information of the wireless lan meets a transmission delay threshold and a transmission delay variance threshold in the first network signal quality condition by comparing a relationship between the mean value and the variance of the RTT data and a preset RTT value and variance.

Alternatively, when the user terminal 1 detects that the transmission rate of the wireless local area network reaches (may be understood to be less than or equal to) a rate threshold, or the transmission bandwidth reaches (may be understood to be greater than or equal to) a credit threshold, or the delay bandwidth product reaches (may be understood to be greater than or equal to) a delay bandwidth product threshold, or the bandwidth utilization reaches (may be understood to be less than or equal to) a bandwidth utilization threshold, it may be determined that the network signal status information of the wireless local area network does not satisfy the first network signal quality condition. For example, the network signal status information of the wireless local area network may be determined not to satisfy the first network signal quality condition when any of the following conditions is satisfied: the transmission rate of the wireless local area network is 100MB/S, and the rate threshold value is 150 MB/S; or the transmission bandwidth of the wireless local area network is 200M, and the bandwidth threshold is 150M; or the time delay bandwidth product of the wireless local area network is 105bit/s, and the threshold value of the time delay bandwidth product is 100 bit/s; or the bandwidth utilization is 80% and the bandwidth utilization threshold is 85%.

It is to be understood that, before the implementation of the embodiment of the present invention, the first threshold determining unit 17 may determine the first quality condition threshold of the first network signal quality condition according to the data type of the service data to be transceived when the current network of the network to which the first data channel is currently accessed is a wireless local area network. The service data may be various types of multimedia data, such as audio, video, or text data. Optionally, when the service data is video data or instant fighting game data, a better network signal is needed to realize stable transceiving of the video data, so that the determined first quality condition threshold is larger, and optionally, when the service data is text character data, non-fighting game data, or the like, the service data can be transceived without high network signal quality requirements, so that the determined first quality condition threshold is smaller. The first quality condition threshold of the first network signal quality condition may be determined according to the data type of the service data to be received and transmitted by presetting the first quality condition threshold corresponding to the different types of service data.

In this embodiment of the present invention, when the network signal status information of the wireless local area network needs to be smaller than the first quality condition threshold, but the detected network signal status is larger than the first quality condition threshold, it may be considered that the network signal status information of the wireless local area network does not satisfy the first network signal quality condition, that is, the current network signal status of the wireless local area network is not good enough. When the network signal status information of the wireless local area network does not satisfy the first network signal quality condition, the second information detecting unit 15 may detect the network signal status information of the cellular data network through the second data channel, and determine whether to transceive the service data through the second data channel.

in a specific implementation, when the second information detecting unit 15 detects that the network signal status information of the cellular data network meets the second network signal quality condition, the first channel switching unit 12 may receive and transmit the service data through the second data channel of the user terminal. It is to be appreciated that the second network signal quality condition can include at least one second quality condition threshold comprising at least one of a transmission delay threshold, a transmission delay variance threshold, a rate threshold, a bandwidth threshold, a throughput threshold, and a delay bandwidth product threshold.

It can be understood that, before the embodiment of the present invention is executed, when the current network of the network to which the first data channel is currently accessed is a cellular data network, the second threshold determining unit 18 may determine the second quality condition threshold of the second network signal quality condition according to the data type of the service data to be received and transmitted, and a specific determination method may refer to the process of determining the first instruction condition threshold in the first threshold determining unit 17, which is not described herein again.

In this embodiment of the present invention, when the network signal status information of the cellular data network is required to be greater than the second quality condition threshold, and the detected network signal status information is also greater than the second quality condition threshold, it may be considered that the network signal status information of the cellular data network satisfies the second network signal quality condition, that is, when the current network signal status of the cellular data network is better, the first channel switching unit 12 may receive and transmit the service data through the second data channel of the user terminal.

In an optional embodiment of the present invention, the user terminal 1 may send an RTT detection packet through the second data Channel, that is, the Backup data Channel, determine whether the Backup data Channel is reachable with low latency based on the sent RTT detection packet, and if the Backup data Channel is reachable with low latency, determine that the network signal state information of the cellular data network satisfies a transmission latency threshold in the second network signal quality condition.

it can be understood that, when the first channel switching unit 12 detects that the network signal status information of the wireless local area network does not satisfy the first network signal quality condition and the network signal status information of the cellular data network satisfies the second network signal quality condition, the second data channel of the user terminal is used for transceiving the service data, during the process that the first channel switching unit employs the second data channel for transceiving the service data, the third channel switching unit 14 can detect the network signal status information of the wireless local area network at any time through the first data channel, and when it detects that the network signal status information of the wireless local area network satisfies the first network signal quality condition, it can switch to transceiving the service data through the first data channel, that is, when the network status of the wireless local area network is good, the transceiving of the service data can be switched from the second data channel to the first data channel, and the wireless local area network can be continuously used.

in a specific implementation, when the first channel switching unit 12 detects that the network signal status information of the wireless lan satisfies the first network signal quality condition (for example, when the network signal status information is smaller than a first quality condition threshold, the obtained network signal status information is smaller than the first quality condition threshold), that is, when the network status of the wireless lan is better, the second channel switching unit 13 may receive and transmit the service data through the first data channel.

a first delay detecting subunit 111, configured to detect a round-trip transmission delay from sending the data probe packet to receiving a feedback message returned by the access device of the wireless local area network;

in a specific implementation, when the network signal state information of the wireless local area network is transmission delay or transmission delay variance, the first delay detecting subunit 111 may detect a round-trip transmission delay from sending the data probe packet to receiving a feedback message returned by the access device of the wireless local area network, where the round-trip transmission delay may indicate a time period from sending the data probe packet to receiving the feedback message by the user terminal, that is, a round-trip time of service data between the user terminal and the access device of the wireless local area network.

A first information detection subunit 112, configured to determine the transmission delay or the transmission delay variance according to the round-trip transmission delay obtained through at least two detections;

it is to be understood that the first delay detecting subunit 111 may obtain the round trip transmission delay obtained by at least two detections, for example, the first delay detecting subunit 111 obtains the round trip transmission delay every 2s for 5 times, and the first information detecting subunit 112 may obtain a delay mean and a delay variance of the round trip transmission delay obtained by 5 times respectively. It is understood that the delay mean and the delay variance may represent network signal status information of the currently accessed wireless local area network.

Further, the first information detecting subunit 112 may determine the delay mean as network signal state information of transmission delay in the network signal state information of the wireless local area network, or may determine the delay variance as network signal state information of transmission delay variance in the network signal state information of the wireless local area network.

in a specific implementation, when the network signal status information of the cellular data network is transmission delay, the second delay detection subunit 151 may detect a round-trip transmission delay from sending the data probe packet to receiving a feedback message returned by the access device of the cellular data network, where the round-trip transmission delay may indicate a time period from sending the data probe packet to receiving the feedback message by the second delay detection subunit 151, that is, a round-trip time of service data between the user terminal 1 and the access device of the cellular data network.

A second information detection subunit 152, configured to analyze round-trip transmission delay obtained by at least two detections, and determine the transmission delay;

in a specific implementation, the second information detecting subunit 152 may obtain the maximum transmission delay of the round-trip transmission delays obtained through at least two detections, for example, the second delay detecting subunit 151 obtains the data transmission delay once every 2s for 5 times in total, and the second information detecting subunit 152 may analyze and compare the 5 obtained round-trip transmission delays for the 5 times, so as to obtain the maximum transmission delay therein. It should be noted that, when the maximum transmission delay is smaller than the transmission delay threshold in the second quality condition threshold, it may be considered that the second data channel is satisfied with low delay.

Further, the second information detecting subunit 152 may determine the maximum transmission delay as the network signal state information of the transmission delay in the network signal state information of the cellular data network.
