[0003] This disclosure belongs to the field of communication technology, and specifically relates to a resource management method, apparatus, communication equipment, and readable storage medium. Background Technology

[0004] For high-speed or ultra-high-speed mobile terminals and / or base stations in mobile communications, existing mobility management mechanisms are insufficient for managing mobility and allocating resources in such scenarios. For example, special terminals like drones, due to their flight characteristics (such as different flight speeds and altitudes) leading to different channel models and propagation characteristics, suffer from severe uplink interference to ground terminals and strong downlink interference due to the physical cell model and resource-sharing model of all terminals within a cell in existing technologies. Furthermore, the numerous handover and reconstruction processes generate significant service interruptions and signaling overhead, hindering the performance improvement of drones. Therefore, effectively managing resources in communication node scenarios like drones is a pressing issue that needs to be addressed. Summary of the Invention

[0130] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0131] The terms "first," "second," etc., used in this disclosure and in the claims are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this disclosure can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," "1st," "2nd," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0132] In addition to the problems mentioned above, due to the high-speed movement of satellites (e.g., a speed of 7.56 km / s), even a stationary terminal cannot avoid frequent handovers (e.g., handover (HO) frequencies of seconds, tens of seconds, or hundreds of seconds). On the other hand, the coverage of non-terrestrial networks (NTNs) can reach hundreds or even thousands of kilometers, with propagation delays of tens to hundreds of milliseconds. This will lead to extremely high latency and signaling storms caused by a large number of terminal handovers in NTN scenarios. Furthermore, regarding handover interruption latency, the handover delay is highly dependent on the processing delays of both the base station and the terminal. The processing time depends on various factors and is highly implementation-dependent. Additionally, satellite handover under a regenerative architecture presents another challenge: research towards a transparent forwarding mode, where only RF filtering, frequency conversion, and amplification are located in the satellite, while protocol functions reside in the terrestrial base station. Therefore, this technology is simpler and more feasible to implement; however, in the regenerative architecture, the protocol functions of the base station's physical layer (PHY), medium access control (MAC), radio link control (RLC), packet data convergence protocol (PDCP), service data adaptation protocol (SDAP), and radio resource control (RRC) layers are all located on the satellite payload, requiring additional solutions to the terminal-satellite interaction and security issues. Therefore, a new technology is urgently needed to solve the mobility management and resource allocation problems in scenarios involving high-speed or ultra-high-speed mobile terminals and / or base stations in mobile communications.

[0133] The communication system used in this disclosure embodiment may include a network node and a first communication node (or a first communication device); the first communication node includes a terminal or other heterogeneous devices, such as glasses, wearable devices, handheld devices, aircraft, hot air balloons, etc. The network node in this disclosure may be a network device, that is, a device that communicates with the first communication node; the network node may also be a base station that provides communication coverage within a certain area and can communicate with the first communication node (e.g., a terminal) located within that area; for example, the network node may be a base station in various communication systems, such as an evolved Node B (eNB) in a Long-Term Evolution (LTE) system, or a base station in a 5G system, a New Radio (NR) system, or a 6G system. The first communication node can be one or more base stations, transmitting points, receiving points, central units, distribution units, building baseband units (BBU), remote radio units (RRU), relays, integrated access and backhaul (IAB), smart metasurfaces, communication balloons, flying aircraft base stations, antennas, satellite base stations, terminals communicating via sidelinks, etc.; the first communication node can also be a terminal, or other modules with specific communication functions; the first communication node can also have functions such as providing sensing capabilities and / or artificial intelligence (AI); the first communication node can also include core network nodes, such as user plane functions (UPF), application functions (AF), mobility management entities (MME), access and mobility management functions (AMF), core network integrated equipment, or other network elements used for connection establishment.

[0134] In this article, "service" can refer to at least one of the following concepts: service, PDU session, Quality of Service (QoS) flow, stream or service data flow, radio bearer, logical channel.

[0135] The resource management method, apparatus, communication device, and readable storage medium provided in this disclosure will be described in detail below with reference to the accompanying drawings and through specific embodiments and application scenarios.

[0136] Please refer to Figure 1, which is a flowchart of a resource management method provided in an embodiment of this disclosure. This method is applied to a first network node, such as a base station. As shown in Figure 1, the method includes the following steps:

[0137] Step 11: The first network node sends first information to at least one of the m network nodes, where m is an integer greater than 1.

[0138] In this embodiment of the disclosure, the first network node can be understood as the current serving network node, such as the current serving base station.

[0139] The m network nodes can be understood as other network nodes besides the first network node during the movement of the first communication node. For example, other network nodes besides the first network node on the path of the first communication node, such as the network nodes that the first communication node will pass through after passing the first network node, that is, the m network nodes arranged along the path of the first communication node, such as the first base station, the second base station, ..., the mth base station.

[0140] The m network nodes include at least a second network node. This second network node can be a network node that the first communication node (e.g., a drone terminal) passes through first, such as the first network node. That is, due to the continuous movement of the drone terminal, the terminal is served by the first network node within time t1. At time t2, the terminal moves to a location covered by the second network node, leaves the first network node, and connects to the second network node, and so on. Alternatively, the m network nodes can be understood as other network nodes besides the first network node that move to the terminal after a future time, such as satellites or drone network nodes, when the first communication node is almost stationary or moving at a low speed. In other words, due to the movement of network nodes, the first communication node (e.g., the terminal) is served by the first network node within time t1. At time t2, the second network node covers the terminal's location, the terminal leaves the first network node, and connects to the second network node, and so on.

[0141] Sending the first information to at least one of the m network nodes can also be expressed as: sending the first information to at least one of the 1st network node, the 2nd network node, ..., the mth network node.

[0142] For example, the first network node sends the first message to the second network node (i.e., the first network node). This method eliminates the need for the information sent by the first network node to be relayed to subsequent network nodes. Later, when the first communication node needs to connect to the third network node from the second network node, the second network node sends the first and second messages to the third network node. The parameters in the first and second messages are of the same or similar types as those in the first message, but the specific parameter values ​​may be the same or different, depending on the configuration and functionality of the third network node. This process continues in this manner.

[0143] For example, the first network node sends first information, information 1-2, information 1-3, ..., information 1-m to the first network node, the second network node, ..., the m-th network node, respectively. The parameters in information 1-2, information 1-3, ..., information 1-m are of the same or similar type to those in the first information, but their specific parameter values ​​may be the same or different, depending on the configuration and function of each target network node; and so on.

[0144] This method allows subsequent network nodes to send only the content that differs from that sent by the first network node, reducing the need for multiple transmissions of redundant information. For example, when the first communication node needs to connect to the third network node from the second network node, the second network node can simply send the content that differs from that sent by the first network node to the third network node, thus reducing the need for multiple transmissions of redundant information.

[0145] Optionally, sending the first information to at least one of the m network nodes may include at least one of the following:

[0160] (i) Indication information that remains unchanged in terms of safety information;

[0161] (k) Data to be transmitted to the first communication node obtained from the core network.

[0162] Optionally, the resource management method in this embodiment may further include:

[0163] The first network node sends second information to at least one of the m network nodes; the second information is used to instruct the first communication node (such as a terminal) to access the cell and / or beam of at least one of the m network nodes; the access may include, but is not limited to, handover, synchronization, and camping.

[0164] Optionally, the method of transmitting the security information includes at least one of the following:

[0165] ① The first network node informs the second network node of the security key information used by the first network node, such as Kgnb information;

[0166] ② If the first network node does not inform the second network node of the security key information applied to the first network node, such as Kgnb information, the second network node can deduce the security key information applied to the first network node, such as Kgnb information, based on at least one of the security algorithm information, count value, and NAS-Key information provided by the first network node.

[0167] ③ If the first network node does not inform the second network node of the security key information applied to the first network node, such as Kgnb information, the second network node can deduce the security key information applied to the first network node, such as Kgnb information, based on the security algorithm information provided by the first network node and at least one of the count value and NAS-Key information provided by the core network.

[0168] ④ Define a logical PDCP virtual layer, or an anchor PDCP, or virtual security parameters. Related network nodes use the same virtual security parameters, virtual security algorithms, and virtual security information. In other words, security information and network nodes are decoupled.

[0169] ⑤ Introduce security zone information, which means that terminals use the same security information within the same security zone (such as at least one of a base station, centralized unit (CU), or cell). That is, if a first communication node (such as a terminal) switches from a first network node to a second network node, and the first and second network nodes are in the same security zone, the first communication node does not need to change and / or update its security information. In other words, the first communication node also does not need to perform Layer 2 user plane reconstruction and / or reset operations.

[0170] Optionally, the security zone information can be sent to the first communication node (e.g., a terminal) via at least one of the following: system messages from the network node, dedicated Radio Resource Control (RRC) signaling, or Medium Access Control Control Element (MAC CE).

[0171] Optionally, if the first communication node detects a change in the security zone, it can initiate a security information update request to the network, and then the network side completes the update configuration of the security information of the first communication node.

[0172] Optionally, the security area information may include, but is not limited to, at least one of the following: information of at least one network node, information of at least one cell, information of at least one beam, information of at least one routing area, information of at least one core network, at least one location information, at least one ground area information, at least one altitude information, security area identifier, etc.

[0173] Optionally, when security zone information needs to be updated, the network may notify the first communication node through at least one of paging information, multicast information, and dedicated signaling to update and / or trigger the security information update process.

[0174] Optionally, when security information in a secure area needs to be updated, the network may notify the first communication node through at least one of paging information, multicast information, and dedicated signaling to update and / or trigger the security information update process.

[0175] Optionally, the first network node also needs to send data received from the core network but not yet sent to the first communication node to a network node (such as a base station) for cell handover to the first communication node, so that the network node can send the data from the core network to the first communication node after the seamless handover is completed.

[0176] The transmission of security information here is mainly applied in scenarios where the security information of the first communication node (such as a terminal) remains unchanged when the first communication node (such as a terminal) or network node moves across different network nodes. This can reduce the frequent interruption of user plane (UP) services caused by security information updates.

[0177] Optionally, the path-related information of the first communication node may include, but is not limited to, at least one of the following:

[0178] The identifiers of network nodes that the first communication node passes through at least one point in time and / or time zone;

[0179] Frequency information of network nodes that the first communication node passes through at least one point in time and / or time zone;

[0180] The identifiers of cells and / or beams traversed by the first communication node at at least one time point and / or time region; for example, if the path of the first communication node is as shown by the arrow in Figure 2A, then the path-related information of the first communication node may include the identifiers of cells and / or beams traversed by the first communication node at different time points, such as PCI 100, PCI 101 and PCI 102; or beam 100, beam 101 and beam 102;

[0181] Location information of the first communication node at at least one point in time and / or within a time region;

[0182] The height information of the first communication node at at least one point in time and / or time zone;

[0183] The angle information of the first communication node at at least one point in time and / or within a time region;

[0184] The first communication node has distance and / or angle information from at least one reference position and / or reference height at at least one point in time and / or time region;

[0185] The frequency information of the cells and / or beams that the first communication node passes through at least one time point and / or time region.

[0186] In one optional implementation, the first network node can determine at least one of the following based on the path-related information of the first communication node: network nodes (such as base stations), cells, frequency information, bandwidth parts (BWP), carriers, and beams that the first communication node passes through at different times. The first network node can then send at least one of the following to at least one of the first, second, ..., m-th network nodes along the path of the first communication node: context information of the first communication node, configuration information of the first communication node at the PDCP, RLC, MAC, and other layers of the first network node, PDU session-related information of the first communication node, resource request information of the first communication node at the second network node, Kgnb information, etc.

[0187] In summary, by sending first information from the first network node to at least one of the m network nodes, the relevant information of the first communication node (such as a terminal) can be transmitted between the network nodes that the first communication node needs to pass through. This enables effective management of resources in communication node scenarios such as drones, avoids service interruptions and signaling overhead caused by a large number of cell change processes such as handover and reconstruction, and improves service performance.

[0188] The main application scenarios of (1) above are as follows: network nodes (such as base stations) obtain terminal path information, such as route planning information, from the core network, network management system, application server (such as Universal Type Server (UTS) or Dedicated Server USS), UAV Traffic Management System (UTM), or terminal. This path information includes at least one of the following: the terminal's destination; the terminal's departure point; the geographical location information of one or more locations passed by the terminal; the base station / cell information passed by the terminal; the error range of the information reported by the terminal (for example, if the error range exceeds one cell, multiple potential base station / cell / frequency information can be given at a specific time point). Such terminals can be communication modules in UAVs, aircraft, or high-speed trains with relatively certain routes, or ordinary terminals with relatively certain or predictable movement paths.

[0189] The above-mentioned solution (2) is proposed to address the problem that the cell handover method in related technologies requires multiple interactions between the terminal, source base station, and target base station to complete the handover process, which is not suitable for high-speed mobile satellite communication scenarios with large latency. The terminal's current serving base station (i.e., the first base station) can send at least one set of synchronization signals to several adjacent nodes of at least one of the base stations, namely the 1st base station, the 2nd base station, ..., the mth base station, to form different virtual cells. Based on the trajectory information of at least one of the base stations, namely the 1st base station, the 2nd base station, ..., the mth base station, and the terminal's location information, the terminal's current serving base station sends the terminal's configuration information to the target base station to which the terminal needs to switch in advance before predicting that the terminal needs to perform a cell change or perform a cell change.

[0190] For example, if the terminal UE is always at position 1, at time t1, the first base station (e.g., satellite base station 1) provides service for position 1; at time t2, the first base station (e.g., the second base station, satellite base station 2) provides service for position 2; ...; at time tm+1, the m-th base station (e.g., satellite base station m+1) provides service for position m+1; then:

[0191] 1) The first base station can send the first information to the second base station before time t2, such as sending the terminal's context information to the second base station so that the terminal can successfully access or switch to the cell and / or beam of the second base station.

[0192] 2) If the first base station sends the terminal's first context information to the second base station, the first base station and / or the second base station need to inform the terminal that at least one of the following operations needs to be performed: rebuild PDCP; restore PDCP; rebuild RLC; reset RLC; clear or not clear the HARQ buffer of the MAC layer; do not continue to send segmented packets of RLC;

[0193] 3) If the first base station sends the terminal's first context information and the terminal's second context information to the second base station, then the first base station and / or the second base station need to inform the terminal that at least one of the following operations is required: PDCP does not need to be rebuilt; PDCP does not need to be restored; RLC does not need to be rebuilt; RLC does not need to be reset; HARQ buffer of the MAC layer does not need to be cleared; and RLC segment packets need to be sent.

[0194] 4) If the first base station sends the terminal's first context information and the terminal's second context information to the second base station, then the first base station and / or the second base station need to inform the terminal that at least one of the following operations is required: PDCP does not need to be rebuilt; PDCP does not need to be restored; RLC does not need to be rebuilt; RLC does not need to be reset; HARQ buffer of MAC layer needs to be cleared; or RLC segment packets need to be sent.

[0195] Optionally, after sending the first information to at least one of the m network nodes, the method in this embodiment further includes at least one of the following:

[0196] The first network node receives third information sent by at least one of the m network nodes;

[0197] The first network node receives m eighth messages sent by at least one of the m network nodes; for example, the first network node may receive m eighth messages sent by each of the m network nodes.

[0198] In this embodiment, the third information includes at least one of the m eighth information pieces; the m eighth information pieces correspond to the m network nodes respectively; for example, the m eighth information pieces include the first information, the second information, ..., the mth information, and the first information, the second information, ..., the mth information corresponds to the first network node, the second network node, ..., the mth network node respectively.

[0199] The information corresponding to the second network node among the m eighth pieces of information includes, but is not limited to, at least one of the following:

[0200] The first communication node's first context information and / or second context information in the second network node may include, for example, the configuration information of the first communication node in the second network node such as PDCP / RLC / MAC, and PDU session-related information of the first communication node.

[0201] The first communication node provides security information to the second network node, such as at least one of the following: Kgnb information, security algorithm information, count value, NAS-Key information, etc.

[0202] For example, a first network node sends a first message to at least one of the first, second, ..., m-th network nodes, where the first message carries Kgnb*1 applied to the first network node; then, the first network node can receive m eighth messages sent by at least one of the first, second, ..., m-th network nodes, where the m eighth messages include the first message, second message, ..., m-th message corresponding to the first, second, ..., m-th network nodes respectively; for example, the first message may carry Kgnb*2, Kgnb*3, ..., Kgnb*m+1 returned by the first, second, ..., m-th network nodes respectively.

[0203] In one optional implementation, the first network node can send resource request information, the time range for resource activation, and Kgnb information to the corresponding first network node, second network node, ..., m-th network node based on the path-related information of the first communication node. Then, the first network node, second network node, ..., m-th network node can return Kgnb*2, Kgnb*3, ..., Kgnb*m+1 to the first network node, respectively. When the first communication node switches from the first network node to the first network node, after the first network node and the core network complete the path switch and obtain the NH / NCC, the first network node can send the NH / NCC to the first communication node and the next-hop second network node. Then, the second network node can use the NH / NCC to update the previously saved kgnb*3 and forward the updated kgnb*3 to the first network node, so that the first network node can update the conditional switching information and inform the first communication node.

[0204] In another optional implementation, the first network node can send resource request information, the resource effective time range, Kgnb information, and the path-related information of the first communication node to the next-hop first network node based on the path-related information of the first communication node. Then, the first network node obtains an NH / NCC value from the core network, determines the next-hop second network node based on the path-related information of the first communication node, and sends resource request information, the resource effective time range, Kgnb*2, the NH / NCC value, and the path-related information of the first communication node to the second network node. Similarly, network node m-1 obtains an NH / NCC value from the core network, determines the next-hop m network node based on the path-related information of the first communication node, and sends resource request information, the resource effective time range, Kgnb*m+1, and the NH / NCC value to the m network node. Afterwards, network nodes from the first to the m network node can return Kgnb*2, Kgnb*3, ..., Kgnb*m+1 to the first network node, which then informs the first communication node of this information.

[0205] Optionally, the resource management method in this disclosure embodiment may further include:

[0206] The first network node sends fourth information to the first communication node, wherein the fourth information is used to indicate the conditions under which the first communication node accesses the cell and / or beam of at least one of the m network nodes; the access may include at least one of handover, synchronization, and camping; the fourth information includes, but is not limited to, at least one of the following:

[0207] The conditions for the first communication node to access the cell and / or beam of at least one of the m network nodes include at least one of the following: the signal measurement value of the first communication node is greater than or equal to a first threshold; the difference between the position of the first communication node and the reference position is less than or equal to a second threshold; the difference between the time the first communication node is in the at least one network node and the reference time is less than or equal to a third threshold; the difference between the angle of the first communication node and the reference angle is less than or equal to a fourth threshold; the height of the first communication node is greater than or equal to a fifth threshold; the time the first communication node is in the at least one network node reaches a sixth threshold; the angle of the first communication node is less than or equal to a seventh threshold; and the power of the first communication node meets the comparison condition of an eighth threshold. The first, second, third, fourth, fifth, sixth, seventh, and eighth thresholds can be set based on actual scenarios and actual needs, and are not limited thereto.

[0208] The time information of the first communication node being at least one of the m network nodes;

[0209] Cell and / or beam information of at least one of the m network nodes;

[0210] The first communication node is located in the cell and / or beam time information of at least one of the m network nodes;

[0211] The identifier of at least one of the m network nodes;

[0212] The first communication node includes the first context information and / or the second context information of the m network nodes, such as the configuration information of at least one of the PHY layer, MAC layer, RLC layer, PDCP layer, SDAP layer, etc.

[0213] By instructing the first communication node to access the cell and / or beam of at least one of the m network nodes, the first communication node can directly utilize the cell and / or beam to achieve handover and / or synchronization, thereby saving signaling overhead.

[0214] For example, in a scenario where the satellite base station is mobile, as shown in Figure 2B, the terminal UE is always in PCI 1. At time t1, the satellite base station gNB 2 provides services to the UE. As the satellite base station moves, at time t2, the satellite base station gNB 1 can provide services to the UE. At this time, the UE can obtain the cell and / or beam from the satellite base station gNB 2 and access the satellite base station gNB 1.

[0215] In one optional implementation, when a first network node determines that a first communication node is about to move into the cell and / or beam of a second network node (e.g., the first network node among m network nodes), the first network node may inform / instruct the first communication node of information related to the second network node; when a second network node (e.g., the first network node among m network nodes) determines that a first communication node is about to move into the cell and / or beam of a next-hop third network node (e.g., the second network node among m network nodes), the second network node may inform / instruct the first communication node of information related to the third network node; ...; when the (m-1)th network node among m network nodes determines that a first communication node is about to move into the cell and / or beam of the mth network node, the (m-1)th network node may inform the first communication node of information related to the mth network node.

[0216] In another alternative implementation, the first network node can inform the first communication node of information related to the m network nodes, namely the first network node, the second network node, ..., the mth network node; when the first network node determines that the first communication node is about to move into the cell and / or beam of the second network node in the next hop, the first network node informs the first communication node through an instruction; ...; when the (m-1)th network node determines that the first communication node is about to move into the cell and / or beam of the mth network node in the next hop, the (m-1)th network node informs the first communication node through an instruction.

[0217] In another optional implementation, the first network node can inform the first communication node of information related to the m network nodes, namely the first network node, the second network node, ..., the mth network node; when the first communication node determines that it is about to move into the cell and / or beam of the first network node, the first communication node starts using the information related to the first network node; when the first communication node determines that it is about to move into the cell and / or beam of the second network node, the first communication node starts using the information related to the second network node; ...; when the first communication node determines that it is about to move into the cell and / or beam of the mth network node, the first communication node starts using the information related to the mth network node.

[0218] Optionally, the resource management method in this disclosure embodiment may further include:

[0219] The first network node sends a fifth message to at least one of the m network nodes; wherein the fifth message includes, but is not limited to, at least one of the following:

[0220] The timeframe for when the resource will take effect; for example, it could be specifying a start point or a time range.

[0221] The key information of the first network node, such as Kgnb information; thereby enabling the corresponding network node to know the key information applied to the first network node;

[0222] Security algorithm information of the first network node;

[0223] The next hop (NH) value of the first network node; based on this NH value, the corresponding network node can update the key with the first communication node as needed;

[0224] The next-hop chain count (NCC) of the first network node; based on this NCC, the corresponding network node can update the key with the first communication node as needed;

[0225] The path-related information of the first communication node; based on this path-related information, the corresponding network node can determine its next-hop network node.

[0226] Optionally, the resource management method in this disclosure embodiment may further include at least one of the following:

[0227] The first network node sends a first list to the first communication node, the first list including the security information of the cell in each of the m network nodes;

[0228] The first network node sends a second list and a count value to the first communication node. The second list includes security information of the cells in each of the m network nodes. The count value is an input parameter for the security algorithm. The count value changes when a key update is required, and sometimes it is related to the number of data packets.

[0229] The first network node sends a third list to the first communication node, the third list including security information of cells in at least one of the m network nodes;

[0230] The first network node sends a fourth list and a count value to the first communication node. The fourth list includes security information of cells in each of at least one of the m network nodes. The count value is an input parameter for the security algorithm.

[0231] The first network node sends a fifth list to the first communication node, the fifth list including security information of the cells in the network nodes that the first communication node will access next;

[0232] The first network node sends a sixth list and a count value to the first communication node. The sixth list includes security information of cells in the next network node accessed by the first communication node; the count value is an input parameter for the security algorithm.

[0233] Therefore, the first communication node can be instructed on the security information of the cell in the network node to which it will subsequently switch and / or synchronize, so that the first communication node can smoothly perform the handover and / or synchronization.

[0234] In one optional implementation, when the first communication node switches from the first network node to the second network node, after the second network node and the core network complete the path switch and obtain the NH / NCC, the second network node can send the NH / NCC to the first communication node and the next-hop third network node. Then, the third network node can use the NH / NCC to update the previously saved kgnb*3 and forward the updated kgnb**3 to the second network node, so that the second network node can update the conditional switching information and inform the first communication node. If the first communication node's path is not unique, and the next hop may be multiple potential network nodes, then the previous-hop network node needs to perform the above operation for multiple next-hop network nodes.

[0235] Optionally, the resource management method in this disclosure embodiment may further include:

[0236] The first network node sends a sixth message to the first communication node; wherein the sixth message is used to instruct the first communication node on a first operation during the process of accessing the cell and / or beam of at least one of the m network nodes; the access may include at least one of handover, synchronization, and camping; the first operation is, for example, a Layer 2 (L2) user plane (UP) operation, and the first operation may include, but is not limited to, at least one of the following:

[0237] Rebuild PDCP, or do not rebuild PDCP;

[0238] Restore PDCP, or do not restore PDCP;

[0239] Rebuild the RLC, or do not rebuild the RLC;

[0240] Reset RLC, or do not reset RLC;

[0241] Clear the HARQ cache of the MAC layer, or do not clear the HARQ cache of the MAC layer;

[0242] Continue sending RLC layer segmented data packets, or stop sending RLC layer segmented data packets.

[0243] Therefore, L2UP operations can be implemented to instruct the first communication node during the process of accessing the cell and / or beam of subsequent network nodes, such as instructing whether PDCP is rebuilt, whether PDCP is restored, whether RLC is rebuilt, whether RLC is reset, whether the HARQ buffer of the MAC layer is cleared, and / or whether the segmented packets of RLC continue to be sent.

[0244] In one optional implementation, regarding path switching, the first network node can inform the second network node whether to initiate a path switch procedure. For example, the second network node can be informed whether to initiate a path switch procedure based on changes in information such as the network node identifier, the Transport Network Layer (TNL) address, the Terminal Endpoint Identifier (TEI) of the first communication node, and / or the GPRS Tunneling Protocol User Plane (GTP-U) tunnel. If the above information remains unchanged, a path switch is not triggered; otherwise, a path switch procedure needs to be triggered. Furthermore, the network node identifier, TNL address, TEI identifier, and / or GTP-U tunnel information can also be associated with the geographical location of the cell coverage area. That is, when a network node moves to a corresponding geographical location, the corresponding network node identifier, TNL address, TEI identifier, and / or GTP-U tunnel information are used.

[0245] Optionally, the resource management method in this disclosure embodiment may further include:

[0246] The first network node sends a seventh message to the first communication node; wherein the seventh message is used to indicate the timer and / or timer duration for security updates after the first communication node accesses the cell and / or beam of at least one of the m network nodes; the access may include at least one of handover, synchronization, and camping; after the security update timer expires, the security information update process is initiated. In this way, by using the security update timer, the timing of initiating the security information update process can be effectively controlled.

[0247] For example, all network nodes could have a single security update timer, such as when the first communication node accesses the cell and / or beam of one of the m network nodes; or each network node could have its own security update timer, such as when the first communication node accesses the cell and / or beam of one of the m network nodes, using the security update timer corresponding to that network node.

[0248] In another alternative implementation, if the Physical Cell Identifier (PCI) of the beams between different communication nodes (such as drones) is the same, but the Synchronization Signal Block (SSB) index and / or Channel State Information Reference Signal (CSI-RS) are different, beam condition switching can be performed using conditions based on time, distance, altitude, and / or location.

[0249] Please refer to Figure 3, which is a flowchart of a resource management method provided in an embodiment of this disclosure. This method is applied to a second network node, such as a base station. As shown in Figure 3, the method includes the following steps:

[0250] Step 31: The second network node receives the first information sent by the first network node. The second network node is one of m network nodes, where m is an integer greater than 1.

[0251] In this embodiment of the disclosure, the first network node can be understood as the current serving network node, such as the current serving base station.

Alternatively, the m network nodes can be understood as other network nodes besides the first network node that move to the first communication node after a future time when the first communication node is almost stationary or moving at a low speed, such as satellites or drone network nodes.

[0312] In one optional implementation, when a first network node determines that a first communication node is about to move into the cell and / or beam of a second network node (e.g., the first network node among m network nodes), the first network node may inform / instruct the first communication node of information related to the second network node; when a second network node (e.g., the first network node among m network nodes) determines that a first communication node is about to move into the cell and / or beam of a next-hop third network node (e.g., the second network node among m network nodes), the second network node may inform / instruct the first communication node of information related to the third network node; ...; when the (m-1)th network node among m network nodes determines that a first communication node is about to move into the cell and / or beam of the mth network node, the (m-1)th network node may inform the first communication node of information related to the mth network node.

[0316] The first network node sends a first list to the first communication node, the first list including the security information of the cell in each of the m network nodes;

[0317] The first network node sends a second list and a count value to the first communication node. The second list includes security information of the cells in each of the m network nodes. The count value is an input parameter for the security algorithm. The count value changes when a key update is required, and sometimes it is related to the number of data packets.

[0318] The first network node sends a third list to the first communication node, the third list including security information of cells in at least one of the m network nodes;

[0319] The first network node sends a fourth list and a count value to the first communication node. The fourth list includes security information of cells in each of at least one of the m network nodes. The count value is an input parameter for the security algorithm.

[0321] The first network node sends a sixth list and a count value to the first communication node. The sixth list includes security information of cells in the next network node accessed by the first communication node; the count value is an input parameter for the security algorithm.

[0322] Therefore, the first communication node can be instructed on the security information of the cell in the network node to which it will subsequently switch and / or synchronize, so that the first communication node can smoothly perform the handover and / or synchronization.

[0323] In one optional implementation, when the first communication node switches from the first network node to the second network node, after the second network node and the core network complete the path switch and obtain the NH / NCC, the second network node can send the NH / NCC to the first communication node and the next-hop third network node. Then, the third network node can use the NH / NCC to update the previously saved kgnb*3 and forward the updated kgnb**3 to the second network node, so that the second network node can update the conditional switching information and inform the first communication node. If the first communication node's path is not unique, and the next hop may be multiple potential network nodes, then the previous-hop network node needs to perform the above operation for multiple next-hop network nodes.

[0332] Therefore, L2UP operations can be implemented to instruct the first communication node during the process of accessing the cell and / or beam of subsequent network nodes, such as instructing whether PDCP is rebuilt, whether PDCP is restored, whether RLC is rebuilt, whether RLC is reset, whether the HARQ buffer of the MAC layer is cleared, and / or whether the segmented packets of RLC continue to be sent.

[0333] Optionally, the resource management method in this disclosure embodiment may further include:

Thus, by using the security update timer, the timing of initiating the security information update process can be effectively controlled.

[0335] For example, all network nodes could have a single security update timer, such as when the first communication node accesses the cell and / or beam of one of the m network nodes; or each network node could have its own security update timer, such as when the first communication node accesses the cell and / or beam of one of the m network nodes, using the security update timer corresponding to that network node.
