Fig. 2 is a flow chart illustrating a method of controlling a relay device according to some exemplary embodiments. In some embodiments, the control method of the relay device described above may be applied to the UE shown in fig. 1, or other similar devices or modules.
As shown in fig. 2, the control method of the relay device provided in the embodiment of the present invention includes the following steps S201 to S202.
S201, the UE determines a signal source of the UE and a location category of the UE.
The signal source of the UE includes a relay device and a base station device, and the location category is used to indicate whether the UE is located in a city.
The location category is a category of the location of the UE at the current time; the signal source is the source of the signal received by the UE at the current time.
As a possible implementation manner, the UE may collect, by using the positioning and collecting module, the position of the UE, and download, by using the map collecting module, map information with the position of the UE as a center and a preset threshold as a radius. Further, the comprehensive processing module of the UE may determine a location category of the UE based on the acquired map information.
The specific implementation of this step may refer to the following description of the embodiment of the present invention, which is not repeated here.
As one possible implementation, the UE may analyze the current signal source through its access signal identification module to determine the signal source of the UE.
Specifically, the downlink data signal received by the UE has a preset information source identifier. The UE may acquire the information source identifier from the received downlink data signal, and determine, according to the acquired information source identifier, whether the downlink data signal received by the UE is from the relay device.
It should be noted that the preset information source identifier may be set in advance in the transmission protocol by the operation and maintenance personnel.
For example, the operator may set an R identifier in a header of a media access control layer (media access control, MAC) of the transport protocol, and the relay device repackages the MAC layer information with the R identifier and then sends the repackaged MAC layer information to the UE; the UE analyzes the signal source by using the access signal identification module.
S202, when the signal source of the UE is the relay equipment and the position category indicates that the UE is located in a city, the UE controls a signal relay module of the relay equipment to enter a dormant state.
As one possible implementation manner, in a case that the UE determines that the signal source of the UE is a relay device and the location class indicates that the UE is located in a city, the UE controls the signal relay module of the relay device to enter a sleep state by sending a measurement report to the relay device.
As another possible implementation, the UE sends the measurement report to the base station device in case it is determined that the signal source of the UE is a relay device and the location class indicates that the UE is located in a city. The base station equipment analyzes the measurement report reported by the UE, and after analyzing the measurement report reported by the UE, the base station equipment sends signaling to the relay equipment to control the signal relay module to enter a dormant state.
The specific implementation of this step may refer to the following description of the embodiment of the present invention, which is not repeated here.
As shown in fig. 3, the method for controlling a relay device according to the embodiment of the present invention further includes the following S203.
S203, controlling the signal relay module to enter an operation state by the UE under the condition that the signal source of the UE is base station equipment and the position category indicates that the UE is not located in a city.
As one possible implementation manner, in a case that the UE determines that the signal source of the UE is a base station device and the location class indicates that the UE is not located in a city, the UE controls the signal relay module of the relay device to enter an operation state by sending a measurement report to the relay device.
As another possible implementation, the UE sends the measurement report to the base station device if it is determined that the signal source of the UE is the base station device and the location class indicates that the UE is not located in a city. The base station equipment analyzes the measurement report reported by the UE, and after analyzing the measurement report reported by the UE, the base station equipment sends signaling to the relay equipment so that the relay equipment controls the signal relay module to enter an operation state.
In one design, the UE may complete the discrimination of the A7 and A8 events through the integrated processing module based on the location, map information, and signal source of the acquired UE.
Specifically, the measurement control module in the base station device issues measurement configuration information to the UE through radio resource control (radio resource control, RRC) signaling. As shown in Table one, measurement configuration information generally includes intra-system events A1-A6 and inter-system events B1-B2. The invention adds A7 and A8 events, as shown in Table one, for making changes to the direct signal source of the user on the high-speed rail.
List one
When the measurement event meets any one of the trigger conditions A1-A6, the UE performs handover connection to ensure that the UE can communicate with a cell with better channel quality than the current serving cell.
When an A7 event is triggered, which means that a high-speed railway enters an urban area, the running speed of a vehicle is reduced, so that signal penetration is reduced, user data transmission in a carriage can be performed in a traditional penetration mode, the density of surrounding base stations is increased, signals become stronger, and huge noise is brought if a repeater is in an active state.
When the A8 event is triggered, the high-speed rail enters an open area of a non-urban area, the density of the base station is reduced, the interference of the repeater is reduced, and the repeater needs to be activated for communication.
And finally, the UE completes the encapsulation and reporting of the A7 or A8 event through a switching encapsulation reporting module, and uploads the dormancy or activation signal of the relay equipment to the relay equipment or the network management equipment through a measurement report.
The specific implementation of this step may refer to the following description of the embodiment of the present invention, which is not repeated here.
Optionally, when the UE determines that the signal source of the UE is a relay device and the location class indicates that the UE is not located in a city, or when the UE determines that the signal source of the UE is a base station device and the location class indicates that the UE is located in a city, the UE continues the current communication mode and the conventional measurement.
The method, the device, the equipment, the system and the storage medium for controlling the relay equipment firstly determine the signal source of the UE and the position category of the UE, and the signal source of the UE comprises the relay equipment and the base station equipment because the position category is used for indicating whether the UE is located in a city or not, so that the state of the signal relay module can be controlled according to the signal source of the UE and the indication condition of the position category. When the signal source of the UE is a relay device and the location class indicates that the UE is located in a city, it represents that the high-speed rail is driven into the city and the relay station is still operating. Because the base stations are densely deployed in the city, when the high-speed rail enters the city, the relay equipment in the working state can generate a large amount of interference so as to interfere with the surrounding base stations of the relay equipment, and at the moment, the relay equipment is controlled to enter the dormant state. I.e. the repeater enters a dormant state and stops the signal relay. The problem of interference of the repeater to the dense area of the base station is effectively avoided.
In one design, in order to determine the location category of the UE, as shown in fig. 4, S201 provided by the embodiment of the present invention may specifically include S2011-S2013 described below.
And S2011, the UE acquires the position of the UE.
As one possible implementation, the UE may obtain the location of the UE from a global positioning system (global positioning system, GPS) through a location acquisition module.
It should be noted that the location of the UE may be the longitude and latitude.
And 2012, the UE acquires map information of the area where the UE is located according to the position of the UE.
As a possible implementation manner, the UE determines the area where the UE is located by using the acquired position as a center of a circle and using a preset threshold as a radius. Further, the UE acquires map information in the area from a preset map information system.
The preset threshold may be 1km, for example.
It should be noted that, the map information may include the degree of dense buildings in the area where the UE is located,
information such as population density, base station density, etc. may also be included.
And S2013, when the density of the buildings in the map is greater than or equal to a preset threshold value, the UE determines that the position category of the UE indicates that the UE is located in a city.
It can be appreciated that the UE determines the location category of the UE based on the intensity of the buildings in the map information.
As one possible implementation, the UE determines that the location category of the UE indicates that the UE is located in a city when the density of buildings in the map is greater than or equal to a preset threshold.
Optionally, the UE may further determine a location category of the UE according to the information such as the population density and the base station density in the map information.
Optionally, the UE may further acquire a historical position of the UE at a historical time, and determine a moving direction of the UE at the current time according to the historical position and the position of the UE at the current time. Further, after the map information is acquired, the UE determines a location category of the UE according to the degree of density of buildings in the moving direction in the map information.
In one design, in order to control the signal relay module of the relay device to enter the sleep state, as shown in fig. 5, S202 provided in the embodiment of the present invention may specifically include the following S2021-S2022.
S2021, the UE generates a first measurement report.
The first measurement report includes a sleep instruction, where the sleep instruction is used to instruct the signal relay module to enter a sleep state.
As one possible implementation, the UE generates the first measurement report if it is determined that the signal source of the UE is a relay device and the location class indicates that the UE is located in a city.
Specifically, in the case that the signal source of the UE is determined to be a relay device, and the location class indicates that the UE is located in a city, the UE generates a measurement report of the A7 event signaling. Wherein, the A7 event instructs the signal relay module to enter a sleep state.
S2022, the UE sends a first measurement report to the relay device.
As one possible implementation, the UE sends the first measurement report to the relay device over a physical uplink control channel (physical uplink control channel, PUCCH).
Correspondingly, after receiving the first measurement report, the relay device analyzes the first measurement report to obtain the dormancy instruction. Further, the relay device responds to the sleep instruction to control the signal relay module to enter a sleep state.
Specifically, the relay device monitors the handover trigger event reported by the terminal at each transmission time interval (transmission time interval, TTI). The relay equipment monitors a first measurement report reported by the UE and analyzes the first measurement report. After the relay device analyzes the A7 event signaling, the relay module is controlled to enter a dormant state according to the analyzed A7 event signaling.

As one possible implementation, the UE generates the second measurement report if it is determined that the signal source of the UE is a relay device and the location class indicates that the UE is located in a city.
Specifically, in the case that the signal source of the UE is determined to be a relay device, and the location class indicates that the UE is located in a city, the UE generates a measurement report of the A7 event signaling. Wherein the A7 event signaling indicates that the signal relay module is dormant.
S2024, the UE sends a second measurement report to the base station device.
As one possible implementation, the UE sends the second measurement report to the base station device through the PUCCH.
Accordingly, the base station apparatus receives the second measurement report.
Specifically, the base station device monitors a second measurement report reported by the UE, and sends the second measurement report to the network management device. The network management equipment monitors a switching trigger event reported by each TTI base station equipment. The network management equipment monitors a second measurement report reported by the UE and analyzes the second measurement report. And after the network management equipment analyzes the A7 event in the second measurement report, generating a dormancy signaling for managing the relay equipment. And the network management equipment transmits the dormancy signaling to the base station equipment. And the base station equipment forwards the dormancy signaling to the relay equipment. Correspondingly, the relay device controls the signal relay module to sleep after receiving the sleep signaling.
It should be noted that the network management device may be a network element device in an operator core network. The relay devices in S2023 and S2024 described above do not support the signaling plane signal full protocol stack parsing. The UE needs to send the measurement report to the network management device, and after the network management device parses the measurement report, the network management device sends signaling for controlling the relay device.
In one design, in order to control the signal relay module of the relay device to enter an operational state, as shown in fig. 7, S203 provided by the embodiment of the present invention may specifically include the following S2031-S2032.
S2031, the UE generates a third measurement report.
The third measurement report includes an opening instruction, where the opening instruction is used to instruct the signal relay module to enter an operating state.
As one possible implementation, the UE generates a third measurement report if it is determined that the signal source of the UE is a base station device and the location class indicates that the UE is not located in a city.
Specifically, in the case that the signal source of the UE is determined to be the relay device and the location class indicates that the UE is located in a city, the UE generates a measurement report of the A8 event signaling. Wherein the A8 event signaling indicates that the signal relay module is operating.

Correspondingly, after receiving the third measurement report, the relay device analyzes the third measurement report to obtain an operation instruction. The relay device controls the signal relay module to enter an operation state according to the dormancy instruction.
Specifically, the relay device monitors a handover trigger event reported by each TTI terminal. And the relay equipment monitors a third measurement report reported by the UE and analyzes the third measurement report. After the relay device analyzes the A8 event in the third measurement report, the signal relay module is controlled to enter an operating state according to the analyzed A8 event command.
The relay apparatuses in S2031 and S2032 are the same as the relay apparatuses in S2021 and S2022, and are both relay apparatuses after capability update. And will not be described in detail herein.
In one design, the relay device monitors for a handover trigger event reported by each TTI base station device. The network management equipment monitors a fifth measurement report reported by the UE and analyzes the fifth measurement report. After the network management equipment analyzes the signaling of other switching events (for example, an A1 event) in the fifth measurement report, the existing signal processing flow is kept for switching. This step is known in the art and will not be described in detail here.
In one design, in order to control the signal relay module of the relay device to enter an operational state, as shown in fig. 8, S203 provided by the embodiment of the present invention may specifically further include the following S2033-S2034.

Specifically, the base station device monitors a fourth measurement report reported by the UE, and sends the fourth measurement report to the network management device. The network management equipment monitors a switching trigger event reported by each TTI base station equipment. The network management equipment monitors a fourth measurement report reported by the UE and analyzes the fourth measurement report. After the network management equipment analyzes the A8 event signaling in the fourth measurement report, the operation signaling of the management and control relay equipment is generated. And the network management equipment sends the operation signaling to the base station equipment. And the base station equipment forwards the operation signaling to the relay equipment. Correspondingly, the relay device controls the signal relay module to operate after receiving the operation signaling.
Note that, the relay devices in S2033 and S2034 have the same functions as the relay devices in S2023 and S2024, and do not support the full protocol stack analysis of the signaling plane signal. And will not be described in detail herein.
In one design, the base station device monitors a sixth measurement report reported by the UE, and sends the sixth measurement report to the network management device. The network management equipment monitors a switching trigger event reported by each TTI base station equipment. The network management equipment monitors a sixth measurement report reported by the UE and analyzes the sixth measurement report. After the network management equipment analyzes the signaling of other switching events (for example, an A1 event) in the sixth measurement report, no instruction for controlling the relay equipment is generated.
