Background
Mobile communication technology is evolving, and in general, the next generation communication technology is more advanced than the previous generation communication technology. For example, the transmission rate of a 5G network is higher than that of a 4G network. However, in practical applications, it may occur that the next-generation communication technology is less effective than the previous-generation communication technology due to operator deployment and the like. For example, the transmission rate of a 4G network is higher in some areas than in a 5G network.
In order for a user to enjoy better service, when the next-generation communication technology is not actually the previous-generation communication technology, the previous-generation communication technology needs to be selected for communication. However, switching from the next generation communication technology to the previous generation communication technology has standard protocols, and these standard protocols cannot guarantee actual service requirements. For example, the switching from 5G to 4G is based on signal strength, such as the 5G network camping, if the signal strength of the current 5G network is higher than a certain threshold, the current 5G network still camps to 5G for data transmission even if the transmission rate is not as high as that of the 4G network, so that the data transmission rate is low, and the data service requirement cannot be met.
In summary, how to effectively solve the problems of handover between different networks is a technical problem that needs to be solved by those skilled in the art.

Detailed Description
In order to provide a better understanding of the present application, those skilled in the art will now make further details of the present application with reference to the drawings and detailed description. It will be apparent that the described embodiments are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.
Referring to fig. 1, fig. 1 is a flowchart of a network switching method according to an embodiment of the present application, where the method includes the following steps:
s101, obtaining a speed limit value of a first network.
The first network belongs to the next generation network with respect to the second network between the first network and the second network. For example, if the first network is 5G, the second network is 4G; if the first network is 4G, the second network is 3G. In this embodiment, the network switching method will be described in detail by taking the first network as a 5G network and the second network as a 4G network, and for the case that the first network and the second network are in other combination forms, reference is made to the description herein and the description thereof will not be repeated.
Considering that the probability that the network rate of the first network is lower than the network rate of the second network is higher under the condition of speed limit of the first network, the current network condition can be detected under the condition that the first network has speed limit, namely the speed limit value of the first network is obtained; otherwise, if the speed limit is not performed on the first network, no operation can be performed.
Specifically, obtaining a speed limit value of a first network includes:
step one, after the first network finishes registration, a protocol data unit session is established.
First, the registration of the first network is completed and a protocol data unit session is established (i.e., a PDU session connection is established, wherein the PDU is Protocol Data Unit protocol data unit). For how to complete the registration of the first network and how to establish the PUD session connection, specific implementation procedures of network registration and establishment procedures of the PUD session may be referred to specifically, and will not be described in detail herein.
And step two, obtaining the speed limit value based on the protocol data unit session.
The second step may specifically include:
step 1, obtaining a session aggregation maximum bit rate cell in a protocol data unit session; wherein the session aggregation maximum bit rate cell includes a downlink session aggregation maximum bit rate and an uplink session aggregation maximum bit rate;
and step 2, determining the maximum bit rate of downlink session aggregation and/or the maximum bit rate of uplink session aggregation as a speed limit value.
Taking the 5G network as an example, after the 5G network completes registration, PDU session is established, and when the network side includes session-AMBR cells (session aggregation maximum bit rate cells) in PDU session establishment accept information, the session-AMBR for downlink and session-AMBR for uplink perform speed limiting control on downlink transmission and uplink transmission.
Where session-AMBR refers to the session aggregate maximum bitrate, session-AMBR for downlink refers to the session aggregate maximum bitrate-downstream (i.e., downstream session aggregate maximum bitrate), session-AMBR for uplink refers to the session aggregate maximum bitrate-upstream (i.e., upstream session aggregate maximum bitrate).
In this embodiment, the downlink session aggregation maximum bit rate may be determined as a speed limit value, the uplink session aggregation maximum bit rate may be determined as a speed limit value, or the downlink session aggregation maximum bit rate and the uplink session aggregation maximum bit rate may be determined as speed limit values based on the downlink session aggregation maximum bit rate and the uplink session aggregation maximum bit rate (e.g., a mean value or a minimum value of the downlink session aggregation maximum bit rate and the uplink session aggregation maximum bit rate may be determined as the speed limit value). The method can be specifically set according to actual service requirements, and if the current scene is more conscious of the upper limit network rate, the maximum bit rate of the uplink session aggregation can be determined as a speed limit value; if the current scenario is more careful about the downlink network rate, the maximum bit rate for downlink session aggregation may be determined as the limiting value.
It should be noted that in practical applications, there is also a situation that the network does not need to be speed-limited, so when the network does not need to be speed-limited, the network switching problem is not needed to be concerned, that is, the speed-limiting value does not need to be acquired. Or when the speed limit value cannot be obtained, there may be no need to perform any operation.
S102, judging whether the speed limit value is lower than a first network theoretical speed.
After obtaining the speed limit value, it may be first determined whether the speed limit value is lower than the first network interest rate. If so, indicating that the actual network speed does not exceed the speed limit value and is lower than the theoretical speed of the first network at the same time under the control of the speed limit value, wherein the network speed is possibly lower than the network speed of the second network; otherwise, it is indicated that the network rate is unlikely to be lower than the network rate of the second network.
According to different judging results, whether the related steps are continuously executed or not can be determined. Specifically, if the judgment result is no, step S105 is executed, i.e. no operation is possible; if the result of the several determinations is yes, step S103 is executed.
S103, switching to a second network mode, and detecting networking configuration of a local second network.
After determining that the speed limit value of the first network is lower than the first network theoretical speed, switching to the second network mode, and detecting the networking configuration of the local second network. Specifically, regarding how to detect the networking configuration of the local second network, the network networking configuration detection procedure may be specifically referred to, which is not described herein in detail.
Preferably, in order to avoid that the switching network mode affects the transmission of data traffic, the switching to the second network mode may be performed in an idle state. Specifically, the data traffic may be effectively monitored, and when no data transmission traffic is found, the network mode is switched to the second network mode.
And S104, if the theoretical rate of the second network corresponding to the networking configuration is larger than the speed limit value, switching the first network into the second network.
Wherein the first network theoretical rate is greater than the second network theoretical rate.
In this embodiment, the correspondence between the networking configuration and the network theoretical rate may be stored in advance, so that after the networking configuration is detected, the second network theoretical rate may be determined.
After knowing the second network theoretical rate, if the second network theoretical rate is found to be greater than the speed limit value, it indicates that the real network rate is lower than the network rate of the second network in the first network, so that the first network can be directly switched to the second network, and a higher actual network rate is obtained.
The first network may be switched to the second network, which may specifically include activating a second network protocol stack, and completing the dial-up on the second network. Thus, the switching from the first network to the second network can be completed.
After the network handover is completed, the data traffic may also be transmitted based on carrier aggregation using the second network after the handover. That is, in order to accelerate data transmission traffic, the data traffic may be transmitted based on a carrier aggregation technique in the second network. That is, when the transmission rate of the 5G network of the user is not satisfactory in some scenes or places, the user can switch to the 4G network based on the 4G network configuration, for example, CA (carrier aggregation, which is a key technology in LTE and is used for increasing the transmission bandwidth) and other technologies to perform data transmission, so as to expect to obtain a higher data transmission rate and improve the user experience.
By applying the method provided by the embodiment of the application, the speed limit value of the first network is obtained; judging whether the speed limit value is lower than a first network theoretical speed; if yes, switching to a second network mode, and detecting networking configuration of a local second network; if the theoretical rate of the second network corresponding to the networking configuration is greater than the speed limit value, switching the first network into the second network; wherein the first network theoretical rate is greater than the second network theoretical rate.
The theoretical rate of the first network is greater than the rate of interest of the second network, i.e., the first network is typically higher than the rate of interest of the second network, but when the first network is rate limiting, the first network is likely to be lower than the second network. In order to meet the data service transmission requirement, when the speed limit value of the first network is found to be lower than the theoretical speed of the first network, the second network mode can be switched, and the networking configuration of the local second network is detected. And switching the first network to the second network under the condition that the interest rate of the second network corresponding to the networking configuration is larger than the speed limit value. Therefore, the current network can be switched to the network with higher network rate, so that the actual data transmission service can be effectively met, and the user experience can be improved.
It should be noted that, based on the above embodiments, the embodiments of the present application further provide corresponding improvements. The preferred/improved embodiments relate to the same steps as those in the above embodiments or the steps corresponding to the steps may be referred to each other, and the corresponding advantages may also be referred to each other, so that detailed descriptions of the preferred/improved embodiments are omitted herein.
In one specific embodiment of the present application, switching the first network to the second network specifically includes:
step one, outputting a network mode switching selection interface to the outside and acquiring input information;
and step two, switching the first network to the second network under the condition that the input information indicates switching to the second network.
For convenience of description, the two steps described above are combined to be described below.
The module resides in a 5G network and establishes PDU session connection; then, detecting whether a session-AMR cell limits the speed of uploading/downloading, if not, ending; if yes, switching to a 4G mode when the network is in an IDLE state, and detecting local 4G network networking configuration; when a user initiates a data service, if the theoretical transmission rate supported by the 4G network networking configuration is greater than the 5G network speed limit value, popping up a prompt to inform the user that the 4G network transmission rate at the current location is higher than the 5G network transmission rate, and enabling the user to select whether to transmit in the 4G network; if the selection of the user is yes, the module is switched to the 4G network for transmission; and if not, continuing to transmit data in the 5G network.
For example, if the current network deployment is TDD-LTE-3CC (4x4 MIMO,Multiple-Input Multiple-Output, i.e., multiple Input Multiple Output system) modulation mode is 256QAM (Quadrature Amplitude Modulation ), the downlink theoretical rate is 1.05Gbps, and if the theoretical rate is higher than the 5G cell speed limit value, a user prompt is given to let the user select which system is specifically used for data transmission.

The theoretical rate of the first network is greater than the rate of interest of the second network, i.e., the first network is typically higher than the rate of interest of the second network, but when the first network is rate limiting, the first network is likely to be lower than the second network.
