Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the 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 invention.

It is to be understood that the terminology used in the embodiments of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used in the examples of the present invention and the appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It should also be understood that the term "and/or" as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items.

For ease of understanding, before describing the present invention, an architecture of a relay network in the related art is first described, as shown in fig. 1, the relay network in the related art includes: terminal 111, repeater 112, and access point 113.

When a terminal needs to transmit data to other protocol networks through an access point, in order to obtain higher link capacity and better coverage, one or more relays may be added between the access point and the terminal, and are responsible for forwarding the data one or more times, that is, the data can reach the terminal through multiple hops. Taking a simpler two-hop relay as an example, a link of an access point-terminal is divided into two links of an access point-repeater and a repeater-terminal, so that a link with poor quality can be replaced by two links with better quality to obtain higher link capacity and better coverage. Meanwhile, for the terminal, the communication between the terminal and the repeater belongs to Device-to-Device (D2D) communication, and the power consumed by data transmission between the terminal and the repeater is low. That is, the terminal communicates with the access point through the relay of the repeater, so that the transmitting power during data transmission is reduced, and the power consumption of the terminal is reduced.

The repeater acts as the only connecting device between the access point and the terminal, and when a problem occurs in the repeater, the communication between the terminal accessing the repeater and the access point is interrupted.

It is understood that the wireless connection between the terminal and the relay, and the wireless connection between the relay and the access point include, but are not limited to: bluetooth, WIFI, zigbee, 3G, 4G, and future 5G.

It should be noted that the terminal 111 can communicate with the relay 112 through downlink and uplink. The downlink (or forward link) refers to the communication link from relay 112 to terminal 111, and the uplink (or reverse link) refers to the communication link from terminal 111 to relay 112. 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 above problem, an embodiment of the present invention provides a method for securing a repeater, as shown in fig. 2, where the method includes the following steps:

s201: and the access point receives the damage information sent by the target repeater and randomly selects a first backup repeater and a second backup repeater from the repeaters to be selected on the basis of the damage information.

In the embodiment of the present invention, the access point may be an upper layer device of a relay such as a gateway, an internetwork connector, a protocol converter, a wireless access point, and the like, and the access point is on a transport layer to implement network interconnection, and can serve as a conversion task for two networks with different upper layer protocols, thereby implementing interconnection of the two networks with different upper layer protocols.

In the embodiment of the present invention, the target repeater refers to a repeater that has a fault sign, for example, the target repeater has a too high temperature, the data transmission rate of the target repeater is too low, and the like, but has not yet actually failed, and can also communicate with the access point and the terminal. The repeater belongs to a same-frequency amplifying device, and is a radio transmission transfer device for enhancing signals in a wireless communication transmission process. The relay may be a relay Device having a Device to Device (D2D) communication connection with the terminal Device. The D2D communication connection may be: Wi-Fi (Wireless Fidelity, Chinese: Wireless Fidelity), Bluetooth (Bluetooth), Zigbee, and Long Term Evolution (LTE) -based D2D communication connection, among others. The repeaters are divided according to the communication system, and can be GSM repeaters, CDMA repeaters, 3G repeaters, 4G repeaters, even future 5G repeaters and the like.

In the embodiment of the present invention, the impairment information may be recorded in a header portion of a data frame between the repeater and the access point, or may be recorded in a content portion of the data frame. The corruption information may be represented by one data bit or by a plurality of data bits. When the damage information is represented by one data bit, when the data bit is set to "1", it indicates that the repeater is damaged, when the data bit is set to "0", it indicates that the repeater is operating well, or, when the data bit is set to "1", it indicates that the repeater is operating well, and when the data bit is set to "0", it indicates that the repeater is damaged. When the damage information is represented by a plurality of data bits, information constituted by any one or a combination of a plurality of characters, numbers, and symbols may be written in the several data bits.

S202: the access point sends a data replication instruction to the target repeater based on the impairment information.

In this embodiment of the present invention, the data copying instruction is used to instruct the target relay to send the cached data to the access point. The cache data comprises data reported to the target repeater by an internet of things terminal under the jurisdiction of the target repeater, configuration information sent to the target repeater by the access point, related information of a channel used by the target repeater and the like. The data reported to the target repeater by the terminal of the internet of things under the jurisdiction of the target repeater may include collected external data sent to the target repeater by the terminal of the internet of things, a network request sent to the target repeater, and the like.

S203: and the access point receives the cache data sent by the target repeater based on the data copying instruction and sends the cache data to a first backup repeater.

In the embodiment of the present invention, the target relay and the first backup relay are both relays managed by the same access point, and the number of the first backup relays may be one or more. When there are multiple first backup repeaters, the sending the cache data to the first backup repeater may specifically be: selecting a repeater with available memory larger than a preset threshold value from repeaters governed by an access point as a first backup repeater, and sending the cache data to the first backup repeater; or selecting a standby repeater from the repeaters governed by the access point as a first backup repeater, and sending the cache data to the first backup repeater. The repeater with the available memory amount larger than the memory threshold value refers to a repeater with sufficient memory capacity to store the cache data of the target repeater, and the memory threshold value may be set according to an actual use situation. Of course, the access point may also select an optimal or better repeater from the repeaters governed by the access point as a unique first backup repeater, and send the cache data to the first backup repeater.

In the embodiment of the present invention, the first backup repeater may include the following two cases: (1) the first backup repeater may not carry any forwarding service at ordinary times, only serves as a backup repeater of the target repeater, and when the target repeater has a fault sign, hot backs up the cache data to the first backup repeater, that is, the first backup repeater is only used for backing up the cache data of the target repeater. (2) The first backup repeater also processes other forwarding services at ordinary times, and when the target repeater fails, the cache data is hot backed up to the first backup repeater, that is, the first backup repeater simultaneously undertakes backup of the cache data of the target repeater and processes other forwarding services.

S204: and the access point sends a terminal switching instruction to the target repeater based on the damaged information, wherein the terminal switching instruction is used for indicating that the terminal of the internet of things under the management of the target repeater is switched to a second backup repeater.

In this embodiment of the present invention, the target repeater and the second backup repeater are both repeaters under the control of the same access point, and the second backup repeater may be one repeater or a plurality of repeaters. When there are multiple second backup repeaters, the second backup repeater may specifically be: selecting relays with the number of terminals smaller than a number threshold value from the relays under the control of the access point as second backup relays; or selecting a relay with a data transmission rate greater than a rate threshold value from the relays managed by the access point as a second backup relay; or selecting a standby repeater from the repeaters managed by the access point as a second backup repeater. The relay with the number of terminals smaller than the number threshold is a relay with a smaller load and capable of receiving more resources to the terminal under the jurisdiction of the target relay. The number threshold may be set according to the actual use, and for example, the number threshold may be set to 50% of the time when the repeater normally performs communication. The relay with the data transmission rate greater than the rate threshold is a relay with stronger processing capability and capable of receiving the terminal under the control of the target relay with higher processing capability. The rate threshold may be set according to the actual use.

Of course, the access point may also select an optimal or better one as the only second backup repeater from the repeaters governed by the access point.

In the embodiment of the present invention, the second backup repeater includes two cases: (1) the second backup repeater does not bear any forwarding service at ordinary times, the second backup repeater is only used as a backup of the target repeater, when the target repeater has a fault sign, the forwarding service of the target repeater is transferred to the second backup repeater, and the second backup repeater only bears the forwarding service transferred by the target repeater. (2) The second backup repeater also bears other forwarding services at ordinary times, when the target repeater has a fault sign, the forwarding services borne by the target repeater are transferred to the second backup repeater, and the second backup repeater simultaneously bears the forwarding services transferred by the target repeater and the other forwarding services.

In the embodiment of the invention, the switching information is used for indicating that the terminal of the internet of things under the management of the target relay is switched to the second backup relay. In a possible implementation manner, after receiving the switching information, the target relay sends the switching information to an internet of things terminal under the management of the target relay, and the internet of things terminal is automatically switched to a second backup relay through the switching information, that is, the internet of things terminal applies for corresponding resources to the second backup relay and sends self-related state information to the second backup relay, and after the second backup relay allocates resources for the internet of things terminal and performs authentication according to the state information, the internet of things terminal is switched to the second backup relay. In another embodiment, the access point directly disconnects the connection between the terminal of the internet of things and the target repeater, and connects the terminal of the internet of things to the second backup repeater, and the terminal of the internet of things is switched to the second backup repeater without knowing by itself, so that the operation of the terminal of the internet of things is avoided, and the power consumption of the terminal of the internet of things is reduced.

In the embodiment of the present invention, the terminal of the internet of things may have different expressions according to different situations, and the terminal of the internet of things (e.g., a cellular phone or a smart phone) may transmit and receive data using a wireless communication system for two-way communication. The internet of things terminal may include 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. An internet of things terminal 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. At the present of the high-speed development of smart home and wearable equipment, the terminal of the internet of things can also be other equipment that can also contain the networking function, for example, intelligent electric light, smart television, intelligent cleaning equipment, intelligent sleep equipment, intelligent supervisory equipment etc. and the form of its performance can be various, for example to intelligent electric light, this intelligent electric light includes but 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.

Further, another relay guaranteeing method is provided in the embodiments of the present invention, as shown in fig. 3, the method includes the following steps:

s301: and the target repeater is connected with the terminal of the Internet of things.

S302: the target repeater sends the impairment information to the access point.

S303: the access point randomly selects a first backup repeater and a second backup repeater from the repeaters to be selected based on the impairment information.

S304: the access point sends a data replication instruction to the target repeater based on the impairment information.

S305: and the target repeater sends the cache data to the access point based on the data replication instruction.

S306: the access point sends the cached data to the first backup repeater.

S307: and the access point sends a position information acquisition instruction to the target access point.

S308: the target repeater sends location information to the access point.

In this embodiment of the present invention, the location information may be encapsulated in status information maintained by the target relay, and the target relay sends the status information to the access point in a real-time manner, or the target relay periodically sends the latest status information to the access point according to a preset update period. The location information may also be encapsulated in impairment information sent by the target relay to the access point, and the access point obtains the location information of the target relay by parsing the impairment information.

S309: the access point sends a move instruction to the second backup relay based on the location information of the target relay,

s310: the second backup repeater moves to a location within the target repeater distance threshold.

In a specific embodiment, since the repeater can only perform effective network forwarding work within a certain distance, if the distance between the repeater and the terminal of the internet of things is too large, the terminal of the internet of things cannot access the repeater, and thus cannot access the network. In order to enable the terminals of the internet of things under the jurisdiction of the target relay to successfully access the network, the second backup relay is a movable relay, when the second backup relay moves to a position within the distance threshold of the target relay according to the movement instruction and the second backup relay is located at the position within the distance threshold of the target relay, the network coverage range of the second backup relay can cover the terminals of the internet of things under the jurisdiction of the target relay, so that connection is established with the terminals of the internet of things under the jurisdiction of the target relay.

It can be understood that the second backup relay may be a backup relay of the target relay, and before the terminal of the internet of things under the jurisdiction of the target relay is switched to the second backup relay, the second backup relay does not carry any forwarding service, and is only used for undertaking the forwarding service transferred from the target relay to the second backup relay when the target relay shows a fault.

In this embodiment, the distance threshold may be set according to network coverage of the target access point and the second backup relay.

S311: and the access point sends a terminal switching instruction to the target repeater based on the damage information.

S312: and the target repeater sends a switching command to the managed Internet of things terminal.

S313: and switching the Internet of things terminal under the management of the target repeater to the second backup repeater.

In a specific embodiment, since the relay can only use the time division duplex technology, since the relay backhaul link and the relay access link use the same link, if the relay performs transceiving communication simultaneously, loop back self-interference may be caused. The relay backhaul link is a link between the gateway and the relay, and the relay access link is a link between the relay and a terminal under the control of the relay. In order to implement simultaneous transceiving communication of the repeaters without causing loop-back self-interference, a first frequency may be used for communication between the gateway and the damaged repeater, and a second frequency may be used for communication between the damaged repeater and a terminal under the control of the damaged repeater, where the first frequency is different from the second frequency.

In another embodiment, in order to implement simultaneous transceiving communication by repeaters without causing loop-back self-interference, a first frame structure may be used for communication between the gateway and the damaged repeater, and a second frame structure may be used for communication between the damaged repeater and a terminal under the control of the damaged repeater, where the first frame structure is different from the second frame structure.

While the method of the embodiments of the present invention has been described in detail, in order to better implement the above-described aspects of the embodiments of the present invention, the following also provides the related apparatus for implementing the aspects.
