Description
Technical Field
The present application relates to the field of communications technologies, and in particular, to a network switching method, module, device, and readable storage medium.
Background
Mobile communication technology is continuously evolving, and in general, next generation communication technology is more advanced than 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, the effect of the next-generation communication technology may be worse than that of the previous-generation communication technology due to operator deployment and the like. For example, the transmission rate of 4G networks is higher in some regions than 5G networks.
In order to make users enjoy better services, the previous generation communication technology needs to be selected for communication when the next generation communication technology is actually inferior to the previous generation communication technology. However, there are standard protocols for switching from the next generation communication technology to the previous generation communication technology, and these standard protocols cannot guarantee actual service requirements. For example, the switching from 5G to 4G is based on signal strength, such as 5G network residence, and if the signal strength of the current 5G network is higher than a certain threshold, even if the transmission rate is lower than that of the 4G network, the current 5G network still resides in 5G for data transmission, so that the data transmission rate is lower and the data service requirement cannot be met.
In summary, how to effectively solve the problems of handover between different networks and the like is a technical problem that needs to be solved urgently by those skilled in the art at present.

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

Detailed Description
In order that those skilled in the art will better understand the disclosure, the following detailed description will be given with reference to the accompanying drawings. It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Referring to fig. 1, fig. 1 is a flowchart illustrating a network handover method according to an embodiment of the present application, where the method includes the following steps:
s101, acquiring a speed limit value of the first network.
It should be noted that, between the first network and the second network, the first network belongs to the next generation network with respect to 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 as an example, and reference may be made to this for the case where the first network and the second network are in other combination forms, which is not described herein again.
Considering that the probability that the network rate of the first network is lower than that of the second network is higher under the condition of limiting the speed of the first network, the current network condition can be detected under the condition that the first network has the speed limit, namely the speed limit value of the first network is obtained; otherwise, if the first network is not speed-limited, no operation is required.
Specifically, the obtaining of the speed limit value of the first network includes:
step one, after the first network finishes registering, establishing a protocol data unit session.
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, where PDU is a Protocol Data Unit). For how to specifically complete the registration of the first network and how to establish the PUD session connection, specific reference may be made to a specific implementation process of network registration and an establishment process of the PUD session, which are not described herein again.
And step two, acquiring the speed limit value based on the protocol data unit conversation.
Wherein, 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 information element comprises a downlink session aggregation maximum bit rate and an uplink session aggregation maximum bit rate;
and 2, determining the maximum bit rate of the downlink session aggregation and/or the maximum bit rate of the uplink session aggregation as a speed limit value.
Taking the 5G network as an example, after the 5G network completes registration, the PDU session is established, and when the network side includes a session-AMBR cell (session aggregation maximum bit rate cell) in the PDU session authorization accept information, specifically, the session-AMBR for downlink and the session-AMBR for uplink perform rate-limiting control on downlink transmission and uplink transmission.
Wherein, session-AMBR refers to session aggregation maximum bit rate, session-AMBR for downlink refers to session aggregation maximum bit rate-downlink (i.e. downlink session aggregation maximum bit rate), and session-AMBR for uplink refers to session aggregation maximum bit rate-uplink (i.e. uplink session aggregation maximum bit rate).
In this embodiment, the downlink session aggregated maximum bit rate may be determined as a speed-limiting value, the uplink session aggregated maximum bit rate may also be determined as a downlink session aggregated maximum bit rate as a speed-limiting value, or may also be determined as a speed-limiting value based on the downlink session aggregated maximum bit rate and the uplink session aggregated maximum bit rate (for example, an average value or a minimum value of the downlink session aggregated maximum bit rate and the uplink session aggregated maximum bit rate may be determined as a speed-limiting value). The setting can be specifically carried out according to the actual service requirements, and if the current scene is more concerned about 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 scene is more concerned about the downlink network rate, the maximum bit rate of the downlink session aggregation can be determined as the speed limit value.
It should be noted that, in practical applications, a situation that the speed limit of the network is not needed may also occur, and therefore, when the speed limit of the network is not needed, the problem of network switching may not be concerned, that is, the speed limit value does not need to be acquired. Or when the speed limit value cannot be acquired, no operation is required to be performed.
And S102, judging whether the speed limit value is lower than a first network theoretical speed.
After the speed limit is obtained, it can be determined whether the speed limit is lower than the first network interest rate. If yes, the actual network speed is indicated to be controlled by the speed limit value, not to exceed the speed limit value and to be lower than the theoretical speed of the first network, and the network speed is possibly lower than the network speed of the second network; the opposite indicates that the network rate is unlikely to be lower than the network rate of the second network.
And according to different judgment results, whether the relevant steps are continuously executed or not can be determined. Specifically, if the determination result is negative, step S105 is executed, i.e., no operation is required; if yes, go to step S103.
S103, switching to a second network mode, and detecting networking configuration of a local second network.
After the speed limit value of the first network is determined to be lower than the theoretical speed of the first network, the second network mode can be switched to, and the networking configuration of the local second network is detected. Specifically, how to detect the networking configuration of the local second network may specifically refer to a network networking configuration detection process, which is not described in detail herein.
Preferably, in order to avoid the impact of switching the network mode on the transmission of the data traffic, the second network mode may be switched to in the idle state. Specifically, the data traffic can be effectively supervised, 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 greater than the speed limit value, switching the first network into the second network.
And the first network theoretical rate is greater than the second network theoretical rate.
In this embodiment, the corresponding relationship between the networking configuration and the network theoretical rate may be stored in advance, so that the second network theoretical rate may be determined after the networking configuration is detected.
After the theoretical rate of the second network is obtained, if the theoretical rate of the second network 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 a second network, which may specifically include activating a second network protocol stack and completing the network-resident dialing in the second network. Thus, the switching from the first network to the second network can be completed.
After the network switching is completed, the switched second network can be used for transmitting the data service based on the carrier aggregation. That is, in order to speed up data transmission traffic, data traffic may be transmitted in the second network based on a carrier aggregation technique. That is, when the transmission rate of the 5G network of the user is not satisfactory in some scenes or places, the user may switch to the 4G network based on the configuration situation of the 4G network, and perform data transmission by using technologies such as CA (carrier aggregation, which is a key technology in LTE and is used to increase the transmission bandwidth), 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; and the first network theoretical rate is greater than the second network theoretical rate.
The first network theoretical rate is greater than the second network interest rate, i.e., the first network is typically higher than the second network rate, but when the first network is rate limited, then 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 mode can be switched to the second network mode, and the networking configuration of the local second network is detected. And under the condition that the interest 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. Therefore, the current network can be switched to the network with higher network rate, the actual data transmission service can be effectively met, and the method is favorable for improving the user experience.
It should be noted that, based on the above embodiments, the embodiments of the present application also provide corresponding improvements. In the preferred/improved embodiment, the same steps as those in the above embodiment or corresponding steps may be referred to each other, and corresponding advantageous effects may also be referred to each other, which are not described in detail in the preferred/improved embodiment herein.
In a 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, under the condition that the input information indicates that the network is switched to the second network, the first network is switched to the second network.
For convenience of description, the above two steps will be described in combination.
The module resides in 5G network and establishes PDU session connection; then, whether a session-AMR cell limits the speed of uploading \ downloading is detected, and if not, the process is finished; 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 of the current location is greater than the 5G network transmission rate, and enabling the user to select whether to transmit in the 4G network; if the user selects yes, the module is switched to the 4G network for transmission; 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 system) and the Modulation mode is 256QAM (Quadrature Amplitude Modulation), the downlink theoretical rate is 1.05Gbps, and if the theoretical rate is higher than the 5G rate-limiting cell value, a user prompt is given to allow the user to select which system the data transmission is performed in.

and the first network theoretical rate is greater than the second network theoretical rate.
The method comprises the steps of obtaining a speed limit value of a first network by applying a module provided by the embodiment of the application; 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; and the first network theoretical rate is greater than the second network theoretical rate.
The first network theoretical rate is greater than the second network interest rate, i.e., the first network is typically higher than the second network rate, but when the first network is rate limited, then 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 mode can be switched to the second network mode, and the networking configuration of the local second network is detected. And under the condition that the interest 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.
