Description

Power supply method and device, target relay node and host node

Technical Field

The application belongs to the technical field of communication, and particularly relates to a power supply method and device, a target relay node and a host node.

Background

In the New Radio (NR) technology of the fifth Generation Mobile communication (5 th Generation Mobile communication,5 g), in order to solve the problem that the cable transmission network is not deployed in place when Access points are deployed densely, an Integrated Access Backhaul (IAB) system is introduced. When no wired transmission network exists, the IAB node accesses the father IAB node based on a wireless backhaul link. The IAB node includes a Distributed Unit (DU) function portion and a Mobile Termination (MT) function portion; the IAB node can rely on its MT to find a parent IAB node (parent IAB node) and establish a wireless connection, i.e., backhaul link, with the DU of the parent IAB node. After an IAB node establishes a complete backhaul link, the IAB node opens its DU function, which may provide radio access service for the UE. A self-return loop includes a host (donor) IAB node, which is directly connected to the wireline transmission network.

In the prior art, although IAB nodes do not need to deploy transmission cables, each IAB node still needs a stable power supply. However, when the IAB system is deployed in a mountain area or a sparsely populated area, the power transmission network may be far away from the IAB node, and the cost of building a power supply line for the IAB node is also high; alternatively, when IAB systems are deployed in urban areas, where IAB nodes are dense and there is no power supply available in the vicinity, it is costly to bury the wires. In these scenarios, solar/wind power may be used to power the IAB node. For example, photovoltaic panels are used to convert solar energy into electrical energy for storage in energy storage cells, which then provide power to the IAB node.

The target operating state may include: a power saving state or a normal state; the power consumption of the target relay node in the power-saving state is smaller than that of the target relay node in the normal state. It should be noted that, the configuration target relay node is adjusted to the power saving state, that is, the configuration target relay node is switched from the normal state to the power saving state; and the configuration target relay node is adjusted to be in a normal state, namely the configuration target relay node is switched to be in a normal state from the power saving state.

Taking the example that the renewable energy conversion device comprises a solar panel, the solar panel converts the output electric energy power, namely the charging power of the energy storage battery.

Optionally, in order to solve the problem that, in the prior art, when power is supplied by using solar energy and an energy storage battery, power supply shortage occurs due to insufficient illumination for a long time, and even the energy storage battery runs out of power, so that the IAB node is turned off, and relay transmission service is interrupted, in an embodiment of the present application, in a mobile communication system scenario in which renewable energy is used to supply power to part or all of relay nodes, a host node or an Operation and Maintenance (OAM) server sends a first configuration message to a target relay node to directly configure the target relay node to enter a power saving state or exit the power saving state, so that the target relay node enters the power saving state or exits the power saving state when receiving the first configuration message, so as to change power consumption of the target relay node; or, the host node or the OAM server does not directly configure the target relay node to adjust to the target running state, but sends the second configuration message to the target relay node, and only configures the target condition that the target relay node enters the power saving state or exits the power saving state, so that the target relay node actively enters the power saving state or exits the power saving state to change the power consumption of the target relay node when the power supply information meets the target condition after receiving the second configuration message.

According to the power supply method provided by the embodiment of the application, the target relay node receives a first configuration message for configuring the target relay node to adjust to the target running state or a second configuration message carrying the target condition and the target running state, the target relay node adjusts to the target running state under the condition that the first configuration message is received so as to change the power consumption of the target relay node, or the target relay node actively adjusts to the target running state under the condition that the second configuration message is received and the power supply information of the target relay node meets the target condition so as to change the power consumption of the target relay node, so that the cruising ability of the target relay node powered by renewable energy is improved, and the ability of the target relay node to continuously provide relay transmission service under the condition that the power supply of the renewable energy is limited can be ensured.

Optionally, the host node or the OAM server may configure the target relay node to send the power supply status report by sending a third configuration message to the target relay node; wherein the third configuration message is used to configure the target relay node to send a power supply status report. The target relay node receives the third configuration message; the target relay node responds to the third configuration message and sends a power supply condition report of the target relay node; wherein the power supply status report is used to report power supply information of the target relay node.

Optionally, the donor node or the OAM server sends the third configuration message to the target relay node. And after receiving the third configuration message, the target relay node responds to the third configuration message and sends a power supply condition report of the target relay node to the host node or the OAM server. After receiving the power supply status report, the host node or the OAM server learns the power supply information of the target relay node, and then sends a first configuration message to the target relay node based on the power supply information of the target relay node under the condition that the power consumption of the target relay node needs to be changed, so as to configure the target relay node to adjust to a target operation state, so as to change the power consumption of the target relay node.

Optionally, the timing at which the target relay node sends the power supply status report includes at least one of:

mode 1: power supply condition reports are sent periodically.

For example, a timer (timer) may be used to time, generate a power supply status report each time the timer expires, and then send the power supply status report. After sending the power supply status report, the timer is restarted.

Mode 2: and sending a power supply condition report when the power supply information of the target relay node meets the target condition.

Taking the example that the power supply information includes the percentage of the remaining power of the energy storage battery, one or more triggering thresholds may be set, for example, 4 triggering thresholds are defined: 30%, 50%, 80% and 100%. When the percentage of remaining charge of the energy storage battery falls below or rises above a certain threshold, a single operation of generating a power supply condition report is initiated. In order to avoid repeated generation and transmission of the power supply status report due to fluctuation in the remaining capacity of the energy storage battery, a prohibit timer (inhibit timer) may be started after each transmission of the power supply status report, and generation and transmission of the power supply status report may be prohibited during the operation of the inhibit timer.

Optionally, after receiving the first configuration message, the target relay node adjusts the target relay node to the target operating state in response to the first configuration message.

Optionally, the donor node or the OAM server sends a first configuration message to the target relay node, where the first configuration message is used to configure the target relay node to adjust to the target operating state. After receiving the first configuration message, the target relay node may adjust to a target operation state to change power consumption of the target relay node.

For example, after receiving the second configuration message, the target relay node adjusts the target relay node to the target operating state in response to the second configuration message when the power supply information of the target relay node satisfies the target condition.

Optionally, the host node or the OAM server sends a second configuration message to the target relay node, where the second configuration message carries the target condition and the target running state. After receiving the second configuration message, the target relay node may actively enter the power saving state or exit the power saving state to change the power consumption of the target relay node when the power supply information satisfies the target condition.

Optionally, in response to a second configuration message sent by a host node, a target relay node adjusts the target relay node to the target operation state and then sends operation information to the host node when power supply information of the target relay node meets the target condition; wherein the operation information is used to represent the target operation state of the target relay node. After the host node receives the operation information, the target operation state of the target relay node can be obtained in time, and the efficiency of service management and resource allocation is improved.

Optionally, in response to a second configuration message sent by the OAM server, the target relay node adjusts the target relay node to a target operation state when the power supply information of the target relay node meets a target condition, and then sends the operation information to at least one of the following devices: the OAM server, the host node, the father relay node and the child relay node. For example, after the host node receives the operation information, the host node can timely acquire the target operation state of the target relay node, thereby improving the efficiency of service management and resource allocation. After the father relay node and the child relay nodes receive the operation information, the target operation state of the target relay node can be timely obtained, the time-frequency resource configuration of the father relay node and the time-frequency resource configuration of the child relay nodes are adjusted based on the target operation state of the target relay node, and the service quality is guaranteed.

Optionally, the operation information may be carried in a Backhaul Adaptation Protocol (BAP) Control Protocol Data Unit (PDU) or a Media Access Control (MAC) Control Unit (CE).

Alternatively, the target relay node may proactively report to the host node or OAM server that it is powered by the renewable energy source after establishing the backhaul link. For example: the target relay node actively sends a first report to a host node or an OAM server, wherein the first report is used for indicating that the target relay node is powered by renewable energy; after the host node or the OAM server receives the first report, the target relay node is informed of being powered by the renewable energy source.

Optionally, when the target relay node is the access IAB node, the DU of the access IAB node may send the first report to the CU of the host IAB node through an F1 application protocol (F1-AP) message; alternatively, the MT accessing the IAB node may send the first report to the CU of the anchor IAB node through a Radio Resource Control (RRC) message. Optionally, the access IAB node sends the first report to the CU of the host IAB node in a random access procedure.

Optionally, after the target relay node establishes the backhaul link, in addition to actively reporting to the host node or the OAM server that the target relay node is powered by renewable energy, the target relay node may also report device information of the renewable energy conversion device that supplies power to the target relay node to the host node or the OAM server; wherein the device information comprises at least one of: the renewable energy conversion device converts the output electric energy power, the capacity of the energy storage battery and the output power of the energy storage battery. The energy storage battery is used for storing the electric energy converted by the renewable energy source conversion device.
