Please refer to FIG. 2. FIG. 2 is a schematic flowchart of a resource management method provided by an embodiment of the present application, applied to a first management node, including the following steps:

Step 201: when the occupancy rate of the first communication resource in the low-level communication domain is greater than or equal to the first value, send a first message, where the first message is used to request the second management node in the high-level communication domain to allocate communication resources, The first management node is located in the low-level communication domain, and the first communication resources are all current communication resources in the low-level communication domain.

Among them, the low-level communication domain and the high-level communication domain belong to the same vehicle short-range communication system.

Wherein, the vehicle short-range communication system includes at least one high-level communication domain and at least one low-level communication domain.

There is a corresponding relationship between the high-level communication domain and the low-level communication domain, and the low-level communication domain determines the corresponding high-level communication domain through the ID in the system message of the high-level communication domain.

The communication resources in the low-level communication domain are allocated by the network devices in the high-priority, and after receiving the allocated communication resources, the network devices in the low-priority allocate the communication resources to the terminal devices in the same communication domain.

The communication resources are time-frequency resources.

Wherein, the first value may be expressed in the form of a percentage or a decimal, for example, it may be 80% or 0.8, or may be other values.

Step 202: in the case that the occupancy rate of the second communication resource in the low-level communication domain is less than a second value, send a second message, the second message is used to request the second management node to release as the first The communication resources allocated by the management node, and the second communication resources are all communication resources in the current lower-level communication domain.

Wherein, the second value may be smaller than the first value.

The communication resources released by the second management node are part of the communication resources in the second communication resources.

The number of communication resources released by the second management node may be determined by the second value, and the smaller the second value, the more communication resources are released.

The communication resources released by the second management node may be determined by the second management node based on the priority of the communication resources, or determined by the second management node based on the received signal strength of the communication resources, or may be determined by the second management node based on the received signal strength of the communication resources. The signal-to-interference-noise ratio can also be determined by the second management node itself.

For example, the communication resources allocated by the second management node to the first management node include A, B, C, and D, and the second management node needs to release 2 communication resources, where the priority of A is 3, and the priority of B is 2. The priority of C is 1 and the priority of D is 1. Generally speaking, the larger the value, the smaller the priority, so A and B are released.

Wherein, the second numerical value can be expressed in the form of a percentage or a decimal, which can be 50% or other numerical values.

It can be seen that in the embodiment of the present application, when the occupancy rate of the first communication resource in the low-level communication domain is greater than or equal to the first value, the first management node sends the first message, and the first message is used to request the high-level communication The second management node in the domain allocates communication resources, the first management node is located in the low-level communication domain, and the first communication resource is all the communication resources currently in the low-level communication domain, or the occupancy rate of the second communication resources in the low-level communication domain When the value is less than the second value, a second message is sent, and the second message is used to request the second management node to release the communication resources allocated for the first management node, and the second communication resources are all communication resources in the current low-level communication domain. Since the first management node requests or releases communication resources from the second management node in the high-level communication domain according to the usage of the communication resources in the low-level communication domain, the communication resources are ensured to be effectively utilized, which is beneficial to improve the utilization rate of the communication resources.

In an implementation manner of the present application, the high-level communication domain is the communication domain where the electronic device to which the communication resource is allocated is located, and the low-level communication domain is the communication domain where the electronic device to which the communication resource is allocated is located.

It can be seen that, in the embodiment of the present application, the division of communication resources is realized by dividing the communication domain, which is beneficial to improve the resource utilization efficiency.

In an implementation manner of the present application, the first value and the second value are broadcast by the second management node to the first management node through a system message;

or, as provided in the agreement;

Alternatively, the second management node is indicated by the first signaling.

It can be seen that, in this embodiment of the present application, there are various ways for the first management node to obtain the first value and the second value, which is beneficial to improving the performance of the network device.

The ingress process accesses the second management node.

The first signaling may be XRC signaling, or may be other signaling with functions similar to XRC signaling.

Wherein, the first connection may be an XRC connection, or may be a connection with other functions similar to radio resource control (Radio Resource Control, RRC) in 5G New Radio (New Radio, NR).

The first signaling is used for the first management node to access the second management node through the first connection.

Among them, the function of XRC is similar to RRC in NR, so the target node for establishing an XRC connection can be in a connected state or a disconnected state.

The target node may enter the connected state by establishing an XRC connection, and enter the disconnected state by releasing the XRC connection.

Wherein, when the target node is in a disconnected state, the target node can obtain broadcast information and system messages of the communication domain.

Wherein, when the target node is in a connected state, the target node may have at least one of the following functions: acquiring broadcast information and system messages in the communication domain, monitoring the physical C-link control information channel, performing discontinuous reception, and performing unicast communication As well as providing channel measurements.

The target node may be a G node or a T node.

Among them, the G node in the low-level communication domain can establish an XRC connection with the G node in the high-level communication domain, and the G node in the same communication domain can establish an XRC connection with the T node. Therefore, the vehicle short-range communication system includes at least one of the following XRC connections: different XRC connection between G nodes in the communication domain, XRC connection between G nodes and T nodes in the same communication domain.

The first information may be MSG3, and the second information may be MSGB.

Wherein, if the first management node accesses the second management node through the contention random access process, MSG3 is sent during the contention random access process, and if the first management node accesses the second management node through the non-contention random access process The node sends MSGB in the process of non-contention random access.

In an implementation manner of the present application, when the first management node and the second management node have established a first connection, the second message is carried by the first management node and sent to the second management node. 2. On the first signaling of the management node;

In the case where the first management node and the second management node do not establish the first connection, the second message includes the third information or the first message sent by the first management node to the second management node Among the four pieces of information, the third information is used by the first management node to access the second management node through a random access procedure, and the fourth information is used by the first management node through non-contention random access The procedure accesses the second management node.

It can be seen that, in the embodiment of the present application, if the random access method between the first management node and the second management node is different, the first management node sends a message in a different manner, which is beneficial to improve the performance of the network device.

In an implementation manner of the present application, the occupancy rate is determined based on all communication resources currently in the lower-level communication domain and currently occupied communication resources in the lower-level communication domain.

Among them, the occupancy rate is the quotient of the occupied communication resources in the current low-level communication domain and all the communication resources in the current low-level communication domain.

For example, if all the communication resources in the current low priority are 30M and the occupied communication resources are 15M, the occupancy rate is 50%.

It can be seen that, in the embodiment of the present application, the occupancy rate is determined by using all current communication resources and occupied communication resources, which is beneficial to improve the accuracy of the occupancy rate.
