It will be apparent that the described embodiments are some, but not all, embodiments of the application. All other embodiments, which can be made by a person skilled in the art without making any inventive effort, are intended to be within the scope of the present application, based on the embodiments of the present application.
The network switching method provided by the embodiment of the application can be suitable for a long term evolution (long term evaluation, LTE) system or other wireless communication systems adopting various wireless access technologies, such as systems adopting access technologies such as code division multiple access (code division multiple access, CDMA), frequency division multiple access (frequency division multiple access, FDMA), time division multiple access (time division multiple access, TDMA), orthogonal frequency division multiple access (orthogonal frequency division multiple access, OFDMA), single carrier frequency division multiple access (SINGLE CARRIER-frequency division multiple access, SC-FDMA) and the like. The network handover method provided in the embodiment of the present application may also be applicable to other wireless communication systems, such as subsequent evolution systems, for example, a fifth generation wireless communication (5 g, also referred to as New Radio (NR)) system (or referred to as NR system), etc., which is not limited herein. Further, embodiments of the present application may also find particular application in Communication systems in NB-IoT, as well as enhanced machine type Communication (eMTC) systems, and the like.
Referring to fig. 1, fig. 1 is a schematic diagram of a system architecture according to an embodiment of the present application. The system architecture provided by the embodiment of the present application includes, but is not limited to, a network terminal and a terminal device (e.g., terminal device 1 to terminal device 6), which is not limited herein. The network terminal and the terminal device shown in fig. 1 may be referred to as a communication device. The network terminal and the terminal equipment provided by the embodiment of the application can establish communication connection to transmit data or signaling, including uplink transmission and downlink transmission. It will be understood that the uplink transmission may be that the terminal device sends data or signaling to the network terminal, and the downlink transmission may be that the network terminal sends data or signaling to the terminal device. The communication connection between the network terminal and the terminal device is not limited to a connection method, and may be directly or indirectly connected through a wired communication method, or may be directly or indirectly connected through a wireless communication method, and the like, and may be specifically determined according to an actual application scenario, which is not limited herein.
The terminal device according to the embodiment of the present application may be a device (device) for providing voice and/or data connectivity to a user, including a wired terminal and a wireless terminal. The wireless terminal may be a handheld device with wireless connectivity or other processing device connected to a wireless modem, a mobile terminal that communicates with one or more core networks via a radio access network (radio access network, RAN). For example, the wireless terminal may be a mobile phone, a computer, a tablet computer, a Personal Digital Assistant (PDA), a Mobile Internet Device (MID), a wearable device, an electronic book reader (e-book reader), and the like. As another example, the wireless terminal may be a gas station, a printer, an electricity meter, a watch, a water dispenser, or the like. As another example, the wireless terminal may also be a portable, pocket, hand-held, computer-built-in or vehicle-mounted mobile device. For another example, the wireless terminal may be a mobile station (mobile station), an access point (access point), or the like. The specific implementation form of the wireless terminal may be determined according to the actual application scenario of the NB-IOT, which is not limited herein. A User Equipment (UE) is a kind of terminal equipment, and is called in the LTE system. For convenience of description, in the following description of the present application, the above-mentioned devices will be described by taking a terminal device as an example. The network terminal according to the embodiment of the application is a communication device deployed in a radio access network for providing a wireless communication function for a terminal device. The network terminals may include various forms of macro base stations, micro base stations, relay stations, access point base station controllers, transceiver nodes (transmission reception point, TRP), and so on. The specific names of network terminals may vary in systems employing different radio access technologies, for example, in LTE networks, a network terminal (or base station) is referred to as an evolved node B (eNB), and in subsequent evolved systems may also be referred to as a new radio node B (gNB). For convenience of description, in the following description of the present application, the above-mentioned devices are collectively referred to as a network terminal.
In various wireless communication systems (such as LTE system and NR system) related to the embodiments of the present application, transmission (including uplink transmission and downlink transmission) of data or signaling between network terminals and terminal devices may have different transmission rates, energy consumption, and so on. The terminal device may transmit data or signaling with network terminals (of different transmission rates, power consumption) in different wireless communication systems at different times. In the embodiment of the present application, a wireless communication system having a larger transmission energy consumption and a faster transmission rate is referred to as a first network (may also be referred to as a high-system network), and a wireless communication system having a smaller transmission energy consumption and a lower transmission rate than the first network is referred to as a second network. For example, compared to an NR system, an LTE system has smaller transmission energy consumption and smaller transmission rate, and thus, the NR system may be referred to as a first network according to the present application, and an LTE system may be referred to as a second network according to the present application. Hereinafter, for convenience of explanation, the first network and the second network will be collectively described.
In the process that the terminal equipment and network terminals (with different transmission rates and energy consumption) in different wireless communication systems transmit data or signaling, the terminal equipment with higher data transmission requirements can be preferentially accessed (or registered) to a first network with larger transmission energy consumption and faster transmission rate so as to more efficiently complete transmission tasks. However, using the first network may result in more energy consumption than the second network when the terminal device is not performing any transmission tasks or performing a small amount of data transmission. Therefore, the terminal device can be instructed to switch from a high-power-consumption network to a low-power-consumption network by the network terminal under the condition of ensuring the transmission requirement of data or signaling between the network terminal and the terminal device, so that the energy consumption of the network terminal and the terminal device can be reduced under the condition of low data volume transmission. For example, when the terminal device uses the first network and the corresponding network terminal detects that the terminal device does not perform any transmission task or performs small data transmission, a network switching instruction may be sent to the terminal device, and after receiving the network switching instruction, the terminal device may switch from the first network to the second network with lower energy consumption, so as to reduce energy consumption of the network terminal and the terminal device in the data transmission process.
Embodiment one:
referring to fig. 2, fig. 2 is a flowchart of a network switching method according to an embodiment of the present application. The method provided by the embodiment of the application can comprise the following steps:
S101, the terminal equipment reports the switching judgment parameters to the network terminal.
In some possible embodiments, in the case where the network currently used by the terminal device is the first network (i.e. the terminal device is currently accessing the first network described above), the terminal device may acquire its current handover decision parameter and send the handover decision parameter acquired by the terminal device to the network terminal. Here, the above-mentioned handover decision parameter is a relevant parameter for the network terminal to decide whether the terminal device is in the low data volume transmission mode.
In a specific implementation, the handover decision parameter may include one or more instant buffer data amounts of the terminal device and/or one or more instant transmission rates. It should be noted that the instant buffered data amount of the terminal device is the total amount of data (which may also be understood as the number of data packets to be currently transmitted by the terminal device) included in the data buffer corresponding to the transmission service executed by the terminal device. The instant transmission rate of the terminal device is the transmission rate corresponding to the transmission service currently executed by the terminal device (which can be understood as the speed of the terminal device currently sending the data packet). The process of the terminal device acquiring and reporting the handover decision parameter to the network terminal will be described in detail below in connection with several optional specific scenarios. It should be noted that, since the number of the instant buffer data amounts and/or the instant transmission rates included in the handover decision parameter has no influence on the specific implementation manner of acquiring and sending the handover decision parameter to the network terminal, in the optional scenario described later, the following description will take the example that the handover decision parameter includes a plurality of instant buffer data amounts and/or a plurality of instant transmission rates.
Optional scenario one:
In this scenario, the handover decision parameter of the terminal device includes a plurality of (here, N1 is a positive integer greater than 1) instant buffer data amounts of the terminal device. In a specific implementation, after the terminal device determines that it needs to report the handover decision parameter to the network terminal, the terminal device may perform data size detection on its data buffer area, so as to obtain N1 instant buffered data sizes. For example, the terminal device may continuously perform N1 times of data amount detection on its data buffer, and determine the N1 times of data amount detection result as N1 instant buffered data amounts. For another example, the terminal device may perform N2 data volume detection on its data buffer continuously to obtain N2 data volume detection results. Then, the terminal device may select N1 data amount detection results with a larger value from the N2 data amount detection results, and then determine the N2 data amount detection results as N1 immediate buffer data amounts. Wherein N2 is a positive integer greater than N1. Of course, the terminal device may also acquire N1 instant buffer data amounts in other manners, which is not particularly limited in the present application.
Then, the terminal device can determine the N1 instant buffer data amounts as the handover decision parameters corresponding to the terminal device, and further send the handover decision parameters to the network terminal. It should be understood here that the terminal device may send the above N1 amounts of instant buffered data to the network terminal at one time, or may send the same to the network terminal immediately after each instant buffered data amount is obtained, which is not particularly limited in the present application.
Optional scenario two:
In this scenario, the handover decision parameter of the terminal device includes a plurality (N1 may also be assumed here) of instantaneous buffered data amounts of the terminal device. In a specific implementation, after the terminal device determines that it needs to report the handover decision parameter to the network terminal, the terminal device may detect the transmission rate between the terminal device and the network terminal, so as to obtain N1 instant transmission rates. For example, the terminal device may continuously perform N1 transmission rate detections on the transmission rate between the terminal device and the network terminal, and determine the result of the N1 transmission rate detections as N1 immediate transmission rates. For another example, the terminal device may perform N3 consecutive transmission rate detections on the transmission rate between the terminal device and the network terminal to obtain N3 transmission rate detection results. Then, the terminal device may select N1 transmission rate detection results with a larger value from the N3 transmission rate detection results, and then determine the N1 transmission rate detection results as N1 immediate transmission rates. Wherein N3 is a positive integer greater than N1. Of course, the terminal device may also acquire the N1 instantaneous transmission rates in other manners, which is not particularly limited in the present application.
Then, the terminal device can determine the N1 instant transmission rates as the handover decision parameters corresponding to the terminal device, and further send the handover decision parameters to the network terminal. Similarly, the terminal device may send the N1 instant transmission rates to the network terminal at one time, or may send the N1 instant transmission rates to the network terminal immediately after each instant transmission rate is obtained, which is not particularly limited in the present application.
Optional scenario three:
In this scenario, the handover decision parameters of the terminal device include a plurality (N1 is assumed here) of instantaneous buffered data amounts and a plurality (N4 is assumed here, N4 is a positive integer greater than or equal to 1) of instantaneous transmission rates of the terminal device. Wherein N1 and N4 may be equal or unequal, which is not limited in the present application. In a specific implementation, after the terminal device determines that it needs to report the handover decision parameter to the network terminal, the terminal device may acquire N1 instant buffer data amounts. Here, the specific process of acquiring N1 instant buffer data amounts by the terminal device may refer to the corresponding process described in the first optional scenario, and will not be described herein. In addition, the terminal device may also obtain N4 instant transmission rates. Here, the specific process of acquiring N4 instant transmission rates by the terminal device may refer to the specific process of acquiring N1 instant transmission rates by the terminal device described in the optional scenario two, which is not described herein.
Then, the terminal device can determine the N1 instant buffer data amounts and the N4 instant transmission rates as the corresponding switching decision parameters of the terminal device, and further send the switching decision parameters to the network terminal. Likewise, the terminal device may send the N1 instant buffer data amounts and the N4 instant transmission rates to the network terminal at one time, or may send one of them to the network terminal immediately after the acquisition, which is not particularly limited in the present application.
In practical implementation, the terminal device may specifically transmit its corresponding handover decision parameter to the network terminal through channels such as a Physical Uplink SHARED CHANNEL (PUSCH) and a physical uplink control channel (physical uplink control channel, PUSCH).
In the actual implementation, the terminal device may determine that the terminal device needs to acquire and report the corresponding handover decision parameter to the network terminal when detecting that the preset handover decision parameter reporting period arrives. That is, the terminal device may periodically acquire and report the handover decision parameter. Or the terminal equipment can also determine that the terminal equipment needs to acquire and report the corresponding switching judgment parameters to the network terminal after detecting the reporting instruction from the network terminal. Of course, the terminal device may also adopt other triggering conditions to report its corresponding handover decision parameters, which is not particularly limited in the present application.
S102, the network terminal acquires the switching judgment parameters reported by the terminal equipment.
In some possible embodiments, the network terminal may receive an uplink message carrying the handover decision parameter of the terminal device on the communication resource negotiated with the terminal device, and extract the handover decision parameter of the terminal device from the uplink message.
And S103, if the network terminal judges that the terminal equipment is in a low data volume transmission mode according to the switching judgment parameters, generating a first network switching instruction.
In some possible embodiments, after acquiring the handover decision parameter reported by the terminal device, the network terminal may decide whether the terminal device is in the low data volume transmission mode according to the handover decision parameter. If the network terminal determines that the terminal device is in the low data volume transmission mode, a network switch instruction may be generated (for convenience of distinction, the description will be replaced with the first network switch instruction hereinafter).
In an optional implementation, for the first optional scenario, after acquiring N1 instant buffered data amounts included in the handover decision parameter, the network terminal may acquire a preset buffered data amount threshold corresponding to the terminal device. Here, the preset buffer amount threshold may be determined by the network terminal from a preset buffer amount threshold range. Then, the network terminal may determine whether each of the N1 amounts of instant buffered data is less than the preset buffer threshold. If the network terminal determines that each instant buffer data amount in the N1 instant buffer data is smaller than the preset buffer amount threshold, it may be determined that the terminal device is in the low data amount transmission mode.
In another optional implementation, for the second optional scenario, after acquiring N1 instant transmission rates included in the handover decision parameter, the network terminal may acquire a preset transmission rate threshold corresponding to the terminal device.

Here, the second network switching instruction may be used to instruct the terminal device to switch from the second network currently used by the terminal device to the first network.

In some possible implementations, after the terminal device switches from the first network to the second network, a new handover decision parameter may be detected and acquired, and further reported to the network terminal. Here, these new handover decision parameters may be used for the network terminal to decide again whether the terminal device is in the low data volume transmission mode in the second network, thereby determining whether it is necessary to instruct the terminal device to switch from the currently used second network to the first network.
In a specific implementation, the specific process that the terminal device obtains the new handover decision parameter and sends the handover decision parameter to the network terminal may participate in the specific process that the terminal device reports the handover decision parameter to the network terminal described in the foregoing step S101, which will not be described herein.
