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.
The network switching method provided by the embodiment of the present application may be applicable to a Long Term Evolution (LTE) system or other wireless communication systems using various radio access technologies, for example, systems using access technologies such as Code Division Multiple Access (CDMA), Frequency Division Multiple Access (FDMA), Time Division Multiple Access (TDMA), Orthogonal Frequency Division Multiple Access (OFDMA), 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 applied to other wireless communication systems, such as a subsequent evolution system, for example, a fifth generation wireless communication (5 generation, 5G, also called New Radio (NR)) system (or referred to as NR system), and the like, which is not limited herein. Further, the embodiments of the present application may also be specifically applied to a Communication system in NB-IoT, an enhanced Machine Type Communication (eMTC) system, and the like.
Referring to fig. 1, fig. 1 is a schematic diagram of a system architecture provided in 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 terminal devices (e.g., terminal devices 1 to 6), and is not limited herein. Both the network terminal and the terminal device shown in fig. 1 may be referred to as communication means. The network terminal and the terminal device provided by the embodiment of the application can establish communication connection to transmit data or signaling, including uplink transmission and downlink transmission. Here, it can 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. In addition, the communication connection between the network terminal and the terminal device is not limited to a connection manner, and may be directly or indirectly connected through a wired communication manner, or may be directly or indirectly connected through a wireless communication manner, and the like, which may be determined according to an actual application scenario, and the present application is not limited herein.
The terminal device according to the embodiments of the present application may be a device (device) providing voice and/or data connectivity to a user, including a wired terminal and a wireless terminal. A wireless terminal may be a handheld device having wireless connection capabilities or other processing device connected to a wireless modem and a mobile terminal that communicates with one or more core networks via a 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 electric meter, a watch, a water dispenser, and the like. As another example, a wireless terminal may be a portable, pocket, hand-held, computer-included, 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 expression of the wireless terminal may be determined according to an 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 an LTE system. For convenience of description, in the following description of the present application, the above-mentioned devices will be described by taking terminal devices as examples. The network terminal according to the embodiment of the present application is a communication apparatus deployed in a radio access network for providing a terminal device with a wireless communication function. The network terminal may include various macro base stations, micro base stations, relay stations, access point base station controllers, transmission reception nodes (TRPs), and the like. In systems using different radio access technologies, the specific names of network terminals may be different, for example, in an LTE network, a network terminal (or a base station) is called an evolved node B (eNB), and in a subsequent evolved system, it may also be called 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 an LTE system and an NR system) related in the embodiments of the present application, transmission of data or signaling (including uplink transmission and downlink transmission) between a network terminal and a terminal device may have different transmission rates, energy consumption, and the like. The terminal device may transmit data or signaling with the network terminal (of different transmission rate, energy consumption) in different wireless communication systems at different times. In the embodiment of the present application, a wireless communication system with higher transmission energy consumption and faster transmission rate is referred to as a first network (which may also be referred to as a high-standard network), and a wireless communication system with lower transmission energy consumption and lower transmission rate than the first network is referred to as a second network. For example, compared to the NR system, the LTE system has smaller transmission energy consumption and smaller transmission rate, and thus the NR system may be referred to as the first network related to the present application, and the LTE system may be referred to as the second network related to the present application. Hereinafter, for convenience of explanation, the description will be collectively made with the first network and the second network.
In the process of transmitting data or signaling between the terminal device and the network terminals (with different transmission rates and energy consumptions) in different wireless communication systems, the terminal device with higher data transmission requirements can be preferentially accessed (or registered) into the first network with higher transmission energy consumption and faster transmission rate, so as to complete the transmission task more efficiently. However, when the terminal device does not perform any transmission task or performs a small amount of data transmission, more energy consumption is generated using the first network than the second network. Therefore, the terminal device can be instructed to be switched from the high-power-consumption network to the low-power-consumption network through the network terminal under the condition of guaranteeing 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, when the corresponding network terminal detects that the terminal device does not perform any transmission task or performs small data transmission, the 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, thereby reducing energy consumption of the network terminal and the terminal device in the data transmission process.
The first embodiment is as follows:
referring to fig. 2, fig. 2 is a schematic flowchart of a network handover 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 a case that a network currently used by the terminal device is a first network (that is, the terminal device is currently connected to the first network), the terminal device may obtain a current handover decision parameter thereof, and send the obtained handover decision parameter to the network terminal. Here, the above-mentioned handover decision parameter is a relevant parameter for the network terminal to decide whether or not 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 buffer data size of the terminal device is a total data amount (which may also be understood as the number of data packets currently to be sent by the terminal device) contained in a data buffer corresponding to the transmission service executed by the terminal device. The instant transmission rate of the terminal device is a transmission rate corresponding to a transmission service currently executed by the terminal device (which may also be understood as a speed at which the terminal device currently sends a data packet). The following describes in detail the process of acquiring and reporting the handover decision parameter to the network terminal by the terminal device in combination with several optional specific scenarios. It should be noted that, since the number of the instant buffer data amount and/or the instant transmission rate included in the handover decision parameter has no influence on the specific implementation manner of obtaining and sending the handover decision parameter to the network terminal, in the optional scenario described later, the case where the handover decision parameter includes a plurality of instant buffer data amounts and/or a plurality of instant transmission rates will be described as an example.
Optional scenario one:
in this scenario, the handover decision parameter of the terminal device includes a plurality (here, N1, N1 is a positive integer greater than 1) of instantaneous 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 amount detection on its data buffer to obtain N1 instant buffer data amounts. For example, the terminal device may continuously perform N1 data amount checks on its data buffer, and determine the N1 data amount check results as N1 immediate buffer data amounts. For another example, the terminal device may perform N2 consecutive data amount detections on its data buffer to obtain N2 data amount 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 instant buffer data amounts. Wherein N2 is a positive integer greater than N1. Of course, the terminal device may also obtain the N1 instant buffer data volumes by using other manners, which is not specifically limited in this application.
Then, the terminal device may determine the N1 instant buffer data volumes 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 N1 instant buffer data volumes to the network terminal at one time, or may send the instant buffer data volumes to the network terminal immediately after each instant buffer data volume is obtained, which is not limited in this application.
Optional scenario two:
in this scenario, the handover decision parameter of the terminal device includes a plurality (here, N1 are also assumed) of instantaneous 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 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 for the transmission rate between the terminal device and the network terminal, and determine the results of the N1 transmission rate detections as N1 instantaneous 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 instantaneous transmission rates. Wherein N3 is a positive integer greater than N1. Of course, the terminal device may also obtain the N1 instant transmission rates in other manners, which is not specifically limited in this application.
Then, the terminal device can determine the N1 instantaneous 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 instant transmission rate to the network terminal immediately after obtaining one instant transmission rate, which is not limited in this application.
Optional scenario three:
in this scenario, the handover decision parameters of the terminal device include a plurality (here, N1 are assumed) of instantaneous buffer data amounts and a plurality (here, N4 is assumed, N4 is a positive integer greater than or equal to 1) of instantaneous transmission rates of the terminal device. N1 and N4 may be equal or different, and are not limited in this 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 obtain N1 instant buffer data volumes. Here, the specific process of acquiring the N1 instant buffer data volumes by the terminal device may refer to the corresponding process described in the foregoing optional scenario one, and details thereof are not repeated here. In addition, the terminal device can also obtain N4 instantaneous transmission rates. Here, for a specific process of acquiring N4 instant transmission rates by the terminal device, reference may be made to the specific process of acquiring N1 instant transmission rates by the terminal device described in the foregoing optional scenario two, and details are not repeated here.
Then, the terminal device can determine the N1 instant buffer data volumes and the N4 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 buffer data volumes and the N4 instant transmission rates to the network terminal at one time, or may send one of the N instant buffer data volumes and the N4 instant transmission rate to the network terminal immediately after obtaining the one of the N instant buffer data volumes and the N4 instant transmission rate, which is not limited in this application.
It should be noted that, in an actual implementation, the terminal device may specifically transmit the corresponding handover decision parameter to the network terminal through a channel such as a Physical Uplink Shared Channel (PUSCH) and a physical uplink control channel (PUSCH).
It should be further noted that, in actual implementation, when detecting that a preset handover decision parameter reporting period arrives, the terminal device may determine that it needs to acquire and report its corresponding handover decision parameter to the network terminal. That is, the terminal device may periodically acquire and report the handover decision parameter. Or, the terminal device may also determine that it needs to acquire and report the corresponding handover decision parameter to the network terminal after detecting the reporting instruction from the network terminal. Of course, the terminal device may also use other triggering conditions to report the corresponding handover decision parameter, which is not specifically limited in this application.
S102, the network terminal obtains 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 further 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 the low data volume transmission mode according to the switching judgment parameter, generating a first network switching instruction.
In some possible embodiments, after obtaining 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 switching instruction may be generated (for convenience of distinction, the description will be replaced with the first network switching instruction hereinafter).
In an optional specific implementation, for the optional scenario one, after acquiring the N1 instant buffer data volumes included in the handover decision parameter, the network terminal may acquire a preset buffer data volume threshold corresponding to the terminal device. Here, the preset buffer amount threshold may be determined by the network terminal from a range of preset buffer amount thresholds. Then, the network terminal may determine whether each of the N1 instant buffer data amounts is smaller than the preset buffer amount 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 a low data amount transmission mode.
In another optional specific implementation, for the optional scenario two, after acquiring the N1 instantaneous 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 first network switching instruction may be used to instruct the terminal device to switch a first network that it is currently using to a second network that is lower in power consumption.
In some possible embodiments, if the network terminal determines that the terminal device is not in the low data volume transmission module (it may also be understood that the terminal device is determined to be in the non-low data volume transmission mode), it may wait for the terminal device to report a new handover decision parameter, and perform the operation of deciding whether the terminal device is in the low data volume transmission mode again.

In some possible implementations, after the network terminal generates the first network switching instruction, the network terminal may send the first network switching instruction to the terminal device. For example, the network terminal may send the first network handover command to the terminal device through higher layer signaling (e.g., Radio Resource Control (RRC) signaling). For example, the network terminal may transmit the first network switching instruction to the terminal device through a downlink channel such as a Physical Downlink Shared Channel (PDSCH) and a Physical Downlink Control Channel (PDCCH). The specific implementation form of sending the first network switching instruction to the terminal device by the network terminal is not limited in the present application.

Thus, the requirement of transmission tasks can be guaranteed, and the total energy consumption of each device is reduced.

And when the network terminal determines that the working time of the terminal equipment under the second network reaches the preset time length, the network terminal can generate a second network switching instruction. 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. Here, after the preset time length, the terminal device is switched from the second network to the first network with the faster transmission rate, so that the transmission requirement of the terminal device with more data transmission tasks can be met.

In some feasible implementation manners, after the terminal device is switched from the first network to the second network, the terminal device may detect and acquire a new switching determination parameter, and further report the new switching determination parameter to the network terminal. Here, these new handover decision parameters may be used for the network terminal to again decide 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 handover from the currently used second network to the first network.
In a specific implementation, the specific process of the terminal device obtaining the new handover decision parameter and sending the new handover decision parameter to the network terminal may join the specific process of the terminal device reporting the handover decision parameter to the network terminal, which is described in step S101, and details are not repeated here.

Further, if the network terminal determines that the terminal device is in the low data volume transmission mode according to the new switching determination parameter, a second network switching instruction may be generated and sent to the terminal device. And if the network terminal determines that the terminal equipment is still in the low data volume transmission mode according to the new switching judgment parameter, waiting for the terminal equipment to report the new switching judgment parameter again, and repeatedly executing the operation.
And S118, the terminal equipment receives a second network switching instruction sent by the network terminal and switches the currently used second network to the first network.
