The present invention is described in further detail below with reference to the attached drawing figures.
For ease of understanding, prior to describing the present invention, a prior art internet architecture is first described. The prior art internetwork includes: a terminal 11 and a plurality of forwarding devices 12.
The terminal 11 is connected to one of the forwarding devices 12 in the internet, and the forwarding device 12 accesses the internet through another mode (i.e. a connection mode different from a wireless mode), where the wireless mode includes but is not limited to: the other mode can be an LTE/LTE-A or wired mode. The wireless LTE is exemplified in fig. 1.
Since the terminal 11 is connected to the internet only through one forwarding device 12, if a problem occurs in the forwarding device 12, the terminal 11 cannot communicate with the internet by transmitting through the forwarding device 12.
In order to solve the above problems, the present invention improves the internet architecture of the prior art. As shown in fig. 2, the internet includes: a terminal 10, a first forwarding device 20 and a second forwarding device 30. The terminal 10 is connected to the first forwarding device 20 and the second forwarding device 30 in a wireless manner, and the first forwarding device 20 and the second forwarding device 30 access the internet of things in another manner (i.e. a connection manner different from the wireless manner), where the wireless manner includes but is not limited to: bluetooth, WIFI, etc., and the other mode may be LTE or wired mode.
The internet of things is a network which connects sensors, controllers, machines, personnel, objects and the like together in a new mode by utilizing communication technologies such as local networks or the internet and the like to form the connection between people and objects and between objects and realize informatization, remote management control and intellectualization. The internet of things is an extension of the internet, and comprises the internet and all resources on the internet, and is compatible with all applications of the internet, but all elements (all devices, resources, communication and the like) in the internet of things are personalized and privatized.
The above-described terminal may have different expressions according to different situations, and the terminal 11 (e.g., a cellular phone or a smart phone) may transmit and receive data for two-way communication using a wireless communication system. The terminal 11 may comprise a transmitter for data transmission and a receiver for data reception. For data transmission, a transmitter may modulate a transmit Local Oscillator (LO) signal with data to obtain a modulated Radio Frequency (RF) signal, amplify the modulated RF signal to obtain an output RF signal having the proper transmit power level, and transmit the output RF signal to a base station via an antenna. For data reception, the receiver may obtain a received RF signal via an antenna, amplify and downconvert the received RF signal with a receive LO signal, and process the downconverted signal to recover data transmitted by the base station. The terminal 11 may support communication with multiple wireless systems of different Radio Access Technologies (RATs) (e.g., LTE/TE-a and NR). Each wireless system may have certain characteristics and requirements to efficiently support simultaneous communication for wireless systems utilizing different RATs. A wireless user equipment may also be referred to as a User Equipment (UE), a mobile station, a terminal, an access terminal, a subscriber unit, a station, and so on. The wireless user device may be a cellular phone, a smart phone, a tablet computer, a wireless modem, a Personal Digital Assistant (PDA), a handheld device, a laptop computer, a smartbook, a netbook, a cordless phone, a Wireless Local Loop (WLL) site, a bluetooth device, and so forth. Today, the smart home and wearable devices are developing at a high speed, the terminal 11 may also include other devices with networking functions, such as a smart lamp, a smart television, a smart sweeping device, a smart sleeping device, a smart monitoring device, etc., which may be represented in various forms, for example, for the smart lamp, the smart lamp includes but is not limited to: intelligence desk lamp, intelligence ceiling lamp, equipment such as intelligence wall lamp, for example to intelligent television, it can be three stars brand intelligent television, of course it also can be sharp brand intelligent television, for example to intelligent cleaning equipment, it can be, intelligence robot of sweeping the floor, of course it can also include equipment such as intelligent dust catcher, intelligent garbage disposer, for example to intelligent sleep equipment, it can be: the present invention is not limited to the specific form, number or kind of the above-mentioned terminals. The terminal 11 may be capable of communicating with a wireless system and may also be capable of receiving signals from a broadcast station, one or more satellites in a Global Navigation Satellite System (GNSS), or the like. The terminal 11 may support one or more RATs for wireless communication, such as GSM, WCDMA, cdma2000, LTE/LTE-a, 802.11, and so on. The terms "radio access technology", "RAT", "radio technology", "air interface" and "standard" are often used interchangeably.
The first forwarding device and the second forwarding device may be routers, interaction machines, relay stations, or other network devices with wireless connection and data forwarding functions, and the embodiments of the present invention are not limited to the specific representation forms of the forwarding devices. The interactive machine can be a two-layer switch or a three-layer switch. It will be appreciated that the first forwarding device and the second forwarding device may be the same type of device or may be different types of devices. For example, the first forwarding device and the second forwarding device may both be routers, or the first forwarding device is a router, the second forwarding device is a relay, and so on.
It should be noted that the terminal 11 can communicate with the forwarding device 12 through a downlink and an uplink. The downlink (or forward link) refers to the communication link from the forwarding device 12 to the terminal 11, and the uplink (or reverse link) refers to the communication link from the terminal 11 to the forwarding device. In the LTE/LTE-a scheme, SC-FDMA (Single-carrier Frequency-Division Multiple Access)/OFDM (Orthogonal Frequency Division Multiple Access) and CP (cyclic prefix) are respectively used for uplink and downlink carriers. In the 5G standard, for example, uplink and downlink carriers may be unified, that is, OFDM and CP are used for uplink and downlink.
In order to solve the problem that the data transmission of the whole terminal cannot be normally performed when the load of the first forwarding device is heavy or a failure occurs, the present invention provides a forwarding device switching method based on the internet structure shown in fig. 2, and as shown in fig. 3, the forwarding device switching method according to the embodiment of the present invention includes the following steps:
310: the first forwarding device detects a network transmission rate of data between the first forwarding device and a terminal in the internet of things, wherein the terminal is connected to the first forwarding device.
The network transmission rate of the data between the terminal and the first forwarding device depends on the sum of the uplink network transmission rate and the downlink network transmission rate between the terminal and the first forwarding device. The uplink network transmission rate generally refers to a transmission rate of data sent by the terminal to the first forwarding device, and the downlink network transmission rate generally refers to a transmission rate of data sent by the first forwarding device to the terminal. Of course, in other embodiments, the uplink network transmission rate and the downlink network transmission rate may be defined in opposite directions. The first forwarding device detects an uplink network transmission rate and a downlink network transmission rate of data between the first forwarding device and the terminal, and determines the network transmission rate of the data between the first forwarding device and the terminal according to the uplink network transmission rate and the downlink network transmission rate of the data between the first forwarding device and the terminal. If the network transmission rate of the data between the first forwarding equipment and the terminal is greater than or equal to the preset speed, the first forwarding equipment is indicated to normally work, and the first forwarding equipment is kept to normally work; if the network transmission rate of the data between the first forwarding device and the terminal is less than the preset speed, it indicates that the first forwarding device may have a fault, and step 320 is entered.
It is understood that the wireless connection between the terminal and the first forwarding device includes, but is not limited to: in addition, the wireless connection mode between the terminal and the first forwarding device can be a 2G, 3G, 4G or even a future 5G mode or a wired mode.
320: and the first forwarding equipment automatically restores the factory settings.
In the embodiment of the present invention, the manner of restoring the factory settings of the first forwarding device may include hardware reset and software reset. The factory setting is a default state of the first forwarding device when the first forwarding device leaves the factory, such as a starting interface, a standby mode, an operation shortcut key, a timing reminder and other functions, but the stored data is not deleted. The hardware reset refers to restoring hardware parameters in all the first forwarding devices to initial values, and the software reset refers to pointing a software program to a first instruction of software running in the first forwarding devices. By automatically restoring the first forwarding device to factory settings, it is possible to solve some of the failure problems.
330: and the first forwarding equipment judges whether the automatic factory restoration setting fails. If the first forwarding equipment judges that the automatic factory setting recovery is successful, the fault of the first forwarding equipment can be repaired, and the terminal can continue to be accessed to the internet through the first forwarding equipment; if the first forwarding device determines that the automatic factory reset fails, the failure of the first forwarding device still exists, and the terminal cannot access the internet through the first forwarding device, and then step 340 is performed.
340: and the first forwarding equipment sends a switching command to the terminal.
In the embodiment of the present invention, the first forwarding device carries the handover command in the downlink control signaling. In a specific embodiment, the first forwarding device carries the handover command in the latest downlink control signaling. In another specific embodiment, in order to avoid that the handover command is lost and not received by the terminal, the first forwarding device may repeatedly send the handover command in a plurality of downlink control signaling to ensure that the handover command can be received by the terminal, that is, the first forwarding device may repeatedly send the handover command to ensure that the terminal can successfully receive the handover command, and finally, the handover is successfully performed.
350: and the first forwarding equipment switches the terminal to the second forwarding equipment.
In the embodiment of the present invention, if the first forwarding device fails to repair the fault by automatically restoring the factory settings, the first forwarding device may send a switching command to the terminal, so that the terminal is switched to a second forwarding device based on the switching command, where the second forwarding device is a standby forwarding device of the first forwarding device.
The second forwarding device being a standby forwarding device of the first forwarding device may be understood as: (1) the second forwarding device does not bear any forwarding service at ordinary times, the second forwarding device is only used as a backup for the first forwarding device, when the first forwarding device fails, the forwarding service borne by the first forwarding device is transferred to the second forwarding device, and the second forwarding device only bears the forwarding service transferred by the first forwarding device. (2) The second forwarding device also bears other forwarding services at ordinary times, when the first forwarding device fails, the forwarding service borne by the first forwarding device is transferred to the second forwarding device, and the second forwarding device simultaneously bears the forwarding service transferred by the first forwarding device and other forwarding services.
When the terminal is connected with the first forwarding device and the second forwarding device in a wired manner, the terminal is respectively connected with the first forwarding device and the second forwarding device through different ports. For example, the terminal is connected to the first forwarding device through a first port, and the terminal is connected to the second forwarding device through a second port. And the first forwarding equipment sends a switching instruction to the terminal, and the terminal switches the data transmission between the first forwarding equipment and the first port into the data transmission between the second forwarding equipment and the second port based on the switching instruction after receiving the switching instruction.
When the terminal is connected with the first forwarding device and the second forwarding device in a wireless mode, if the number of the standby forwarding devices of the first forwarding device is more than one, the switching command sent by the first forwarding device to the terminal includes the identifier of the second forwarding device, after the terminal receives the switching command, the identifier of the second forwarding device is obtained from the switching command, and the terminal is switched to the second forwarding device based on the identifier of the second forwarding device. In this embodiment of the present invention, the identifier of the second forwarding device may be a Radio Network Temporary Identity (RNTI) of the second forwarding device, an MAC address of the second forwarding device, or other identifier information that enables the second forwarding device to be identified, which is not limited herein.
It is understood that the number of the standby forwarding devices of the first forwarding device may be one or more. When the number of the standby forwarding devices of the first forwarding device is multiple, the terminal may arbitrarily select one standby forwarding device from the multiple forwarding devices as the second forwarding device. Of course, the terminal may also select an optimal or better standby forwarding device from the multiple standby forwarding devices as the second forwarding device according to the measurement result of the standby forwarding devices.
In some possible implementations, the measurement result of the candidate relay device may include: signal strength between the standby forwarding device and the terminal, load capacity (e.g., data buffering capacity, remaining power, etc.) of the standby forwarding device, current load capacity of the standby forwarding device, information security processing (encryption/decryption) capability, and so on. In practical application, the base station may select an optimal or better standby forwarding device for the terminal according to the measurement result, and use the selected standby forwarding device as the second forwarding device of the terminal.
