[0002] A repeater is a radio frequency (RF) signal amplification and forwarding device. Due to its characteristics, repeaters can be deployed to fill signal gaps or improve signal coverage in scenarios such as elevator shafts or underground parking garages where signal coverage is insufficient or inaccessible. Therefore, the management of repeaters is crucial. Summary of the Invention

[0003] This application provides a management method, communication device, storage medium, and program product for relay devices, aiming to reduce the management cost of relay devices.

[0004] In a first aspect, embodiments of this application provide a management method for a relay device, applied to a relay device that supports the forwarding of radio frequency signals of at least two communication standards; the method includes: receiving a first radio frequency signal; and, in the case where the at least two communication standards include a first communication standard corresponding to the first radio frequency signal and the transmitting device of the first radio frequency signal is a communication device corresponding to a first host cell, forwarding the first radio frequency signal according to first radio frequency forwarding control information corresponding to the first communication standard; wherein, the first host cell is the host cell of the relay device in the first communication standard.

[0005] Secondly, embodiments of this application provide a management method for a relay device, applied to a host base station of the relay device; the relay device supports the forwarding of radio frequency signals of at least two communication standards; the method includes: in response to the access of the relay device, upon obtaining that the relay device supports the forwarding of radio frequency signals of a second communication standard, sending a second inter-system measurement configuration corresponding to the second communication standard to the relay device; wherein, the second communication standard is any communication standard other than the communication standard corresponding to the host base station among the at least two communication standards; the second inter-system measurement configuration includes a second inter-system measurement frequency point corresponding to the second communication standard; the second inter-system measurement frequency point is determined based on the radio frequency forwarding frequency point of the second communication standard supported by the relay device and the inter-system frequency point of a second neighboring cell; the second neighboring cell is a neighboring cell of the host base station corresponding to the second communication standard; receiving a second inter-system measurement report sent by the relay device; wherein, the second inter-system measurement report is an inter-system measurement report sent by the relay device in response to the second inter-system measurement configuration; determining a second host cell of the relay device in the second communication standard based on the second inter-system measurement report, and interacting with the relay device through the second host cell using radio frequency signals.

[0006] Thirdly, embodiments of this application provide a communication device, including: at least one processor; at least one memory for storing at least one program; and when at least one of the programs is executed by at least one of the processors, implementing the management method of the relay device as described in the first or second aspect.

[0007] Fourthly, embodiments of this application provide a computer-readable storage medium storing computer-executable instructions for performing the management method of the relay device as described in the first or second aspect.

[0008] Fifthly, embodiments of this application provide a machine program product, including a computer program or computer instructions, the computer program or computer instructions being stored in a computer-readable storage medium, a processor of a communication device reading the computer program or computer instructions from the computer-readable storage medium, and the processor executing the computer program or computer instructions to cause the communication device to perform the relay device management method as described in the first or second aspect.

This means that a single relay device can forward radio frequency signals from multiple communication standards, thereby reducing deployment and maintenance costs, and ultimately lowering the overall management cost. For a relay device supporting the forwarding of radio frequency signals from multiple communication standards, upon receiving a first radio frequency signal, it can first determine whether the first communication standard corresponding to the first radio frequency signal belongs to one of its supported communication standards, and whether the transmitting device of the first radio frequency signal is the communication device corresponding to the host cell of the first communication standard. If both are true, it indicates that the first radio frequency signal is a supported radio frequency signal. Based on the radio frequency forwarding control information corresponding to the first communication standard, the first radio frequency signal can be forwarded. This ensures reliable forwarding of the radio frequency signal and guarantees the radio frequency forwarding accuracy of the relay device supporting the forwarding of radio frequency signals from multiple communication standards.

[0022] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0023] It should be understood that in the description of the embodiments of this application, the use of terms such as "first" and "second" is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of technical features indicated, or implicitly indicating the order of the technical features indicated. "At least one" refers to one or more, and "more" refers to two or more. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent the existence of A alone, the simultaneous existence of A and B, or the existence of B alone. A and B can be singular or plural. The character " / " generally indicates that the preceding and following related objects are in an "or" relationship. "At least one of the following" and similar expressions refer to any group of these items, including any group of singular or plural items. For example, at least one of a, b, and c can represent: a, b, c, a and b, a and c, b and c, or a and b and c, where a, b, and c can be single or multiple.

[0024] To facilitate understanding of the solutions in the embodiments of this application, some contents involved in the embodiments of this application are described below:

[0025] Traditional radio frequency repeaters only amplify and forward RF signals, amplifying received signals, including interference and noise, in the uplink direction. Therefore, improper deployment of radio frequency repeaters can cause a significant increase in the network noise floor, affecting capacity and spectral efficiency. To address the shortcomings of traditional repeaters, the fifth-generation (5G) communication standard introduced the Network Controlled Repeater (NCR).

[0026] For a framework diagram of NCR, please refer to Figure 1 ,like Figure 1As shown, the NCR includes a Mobile Termination (MT) entity and a Forwarding (Fwd) entity. The MT entity, also known as the communication entity or NCR-MT, establishes a Control Link (C-link) with the 5G base station (gNB) to exchange control information. The Fwd entity, also known as the radio frequency forwarding entity or NCR-Fwd, establishes a Backhaul Link (B-link) with the gNB and an Access Link (A-link) with the user equipment (UE) to amplify and forward uplink (UL) / downlink (DL) RF signals between the gNB and the UE. Specifically, the NCR-Fwd can control RF amplification and forwarding based on the control information received from the gNB; therefore, the control information can also be called RF forwarding control information. It is evident that, compared to traditional RF repeaters, the NCR can collaborate with the gNB and the NCR FWD to perform targeted RF amplification (e.g., specified time slot amplification, beam amplification, etc.) based on the cell coverage of the base station, reducing noise floor suppression.

[0027] Currently, NCR (Non-Controlled Radio Rate) is only introduced in the 5G protocol, not in the 4G communication standard protocol. This means that NCR can only control the RF amplification of 5G (amplifying the power or amplitude of the RF signal), and cannot control the RF amplification of 4G. However, 4G networks are generally used as a backup network for basic coverage, and there is a high probability that 5G blind spots will overlap with 4G (such as in elevator shafts).

[0028] Based on this, this application provides a method for managing relay devices, wherein the relay devices can support the forwarding of radio frequency signals of at least two communication standards. In other words, the forwarding of radio frequency signals of multiple communication standards can be achieved through one relay device. This reduces the number of relay devices deployed, thereby reducing the deployment and maintenance costs of the relay devices, and ultimately reducing the overall management cost of the relay devices.

[0029] It is understood that the relay device is a radio frequency forwarding and amplification device. Therefore, in the embodiments of this application, the forwarding of radio frequency signals by the relay device can be understood as the amplification and forwarding of radio frequency signals. That is, when forwarding radio frequency signals, the radio frequency signals can be amplified, such as by amplifying the power or amplitude, in order to improve the coverage of radio frequency signals.

[0030] For a relay device that supports the forwarding of radio frequency signals from at least two communication standards, it can be considered a co-managed relay device for these at least two communication standards, and deployed as a co-managed relay device for these at least two communication standards. In specific implementation, the co-managed relay device can be hosted in one of the communication standards, accessing a cell under a base station in that communication standard (this base station can be considered the host base station of the co-managed relay device). This cell can be considered the host cell of the co-managed relay device in that communication standard. Then, through interaction with the host base station, the host cell of the co-managed relay device in other communication standards is determined, thereby enabling the co-managed relay device to forward the radio frequency signals sent by the communication devices corresponding to each host cell. The communication devices corresponding to the host cell can include the base station to which the host cell belongs, and the UEs accessing the host cell. It is worth noting that although the co-managed relay device has host cells in multiple communication standards, it may not access base stations of other communication standards besides the hosted communication standard.

[0031] The embodiments of this application do not limit the specific structure of the co-managed relay device. In some embodiments, the co-managed relay device may include a communication entity and a radio frequency forwarding entity, which may specifically be any of the following:

[0032] The co-managed relay device may include a communication entity and a radio frequency forwarding entity. The radio frequency forwarding entity may include at least two radio frequency forwarding logic units that correspond one-to-one with at least two communication standards. Each radio frequency forwarding logic unit is used to forward the radio frequency signal of its corresponding communication standard.

[0033] A radio frequency forwarding entity may include a communication entity and at least two radio frequency forwarding entities that correspond one-to-one with at least two communication standards, each radio frequency forwarding entity being used to forward radio frequency signals of its corresponding communication standard.

[0034] The radio frequency forwarding logic unit or radio frequency forwarding logic entity used for radio frequency signal forwarding can be controlled by the host cell in its corresponding communication standard by the co-managed relay equipment. That is, the radio frequency forwarding logic unit or radio frequency forwarding logic entity can control the amplification and forwarding of the radio frequency signal of the corresponding communication standard according to the control information received from the base station to which the corresponding host cell belongs.

[0035] In the embodiments of this application, the radio frequency forwarding control information corresponding to the communication standard may include at least one of the following: time slot turn-off or turn-on control information of the radio frequency forwarding logic unit or radio frequency forwarding logic entity used to forward the radio frequency signal of the communication standard; noise index (NI) information of the host cell of the co-managed relay device in the communication standard; user number information of the communication standard under the co-managed relay device, radio frequency turn-off of the co-managed relay device, alarm reporting of the co-managed relay device, etc.

[0036] This application does not limit the number of communication standards or their specific forms that the relay device can support for forwarding radio frequency signals. The relay device can support forwarding radio frequency signals of two, three, or more communication standards, depending on the actual situation.

[0037] In some embodiments, the relay device can be a 4G / 5G co-managed relay device, meaning that this relay device can simultaneously perform Long Term Evolution (LTE) and New Radio (NR) radio frequency forwarding. In these embodiments, the 4G / 5G co-managed relay device can be manifested as an NCR, and can be referred to as a 4G / 5G co-managed NCR. The 4G / 5G co-managed relay device can be hosted on 5G or on 4G, depending on the actual situation, and this application embodiment does not limit this.

[0038] 4G5G co-management NCR can be regarded as Figure 1 The improved version of the NCR shown can be found in some examples of the 4G / 5G co-managed NCR structure. Figure 2 ,exist Figure 2 In the 4G5G co-managed NCR, there is one NCR-MT and two NCR-Fwd. One of the NCR-Fwd can be called NR NCR-Fwd, which is used to forward radio frequency signals between gNB and 5G UE and can be controlled by NR host cell. The other NCR-Fwd can be called LTE NCR-Fwd, which is used to forward radio frequency signals between 4G base station (eNB) and LTE UE and can be controlled by LTE host cell.

[0039] The above embodiments can realize the joint deployment of 4G and 5G NCR. In terms of NCR management, the maintenance cost can be further reduced by a unified NCR management system. Therefore, in the scenario of joint deployment of 4G and 5G, the NCR deployment cost and NCR management and maintenance cost of operators can be greatly reduced.

[0040] The deployment method of the relay device provided in this application embodiment will be described in detail below with reference to the accompanying drawings and through some embodiments and application scenarios.

[0041] See Figure 3 , Figure 3 This is one of the flowcharts illustrating the management method for relay devices provided in the embodiments of this application. Figure 3 The management method for the relay equipment shown can be applied to managed relay equipment that supports the forwarding of radio frequency signals for at least two communication standards. In specific implementation, Figure 3The management method for the relay equipment shown can be executed by the co-managed relay equipment, or by components of the co-managed relay equipment, such as the processor, chip, or chip system of the co-managed relay equipment, or by logic modules or software that implement all or part of the functions of the co-managed relay equipment.

[0042] In the case where the relay equipment includes a communication entity and an RF forwarding entity, the reception and forwarding of the following RF signals can be performed by the RF forwarding entity; the reception of the following RF forwarding control information can be received by the communication entity and then sent to the RF forwarding entity so that the RF forwarding entity can forward the RF signals according to the RF forwarding control information.

[0043] like Figure 3 As shown, the management method for relay equipment includes, but is not limited to, the following steps:

[0044] Step 301: Receive the first radio frequency signal.

[0045] The first radio frequency signal can be any radio frequency signal received by the co-managed relay device. It is worth noting that the first radio frequency signal may be a radio frequency signal that the co-managed relay device supports for forwarding, or it may be a radio frequency signal that the co-managed relay device does not support for forwarding.

[0046] As can be seen from the foregoing, the co-managed relay device can forward the radio frequency signals sent by the communication devices corresponding to the host cells of each communication standard. Therefore, the co-managed relay device can determine whether the first radio frequency signal is a radio frequency signal that the co-managed relay device supports forwarding based on the communication standard (which can be called the first communication standard) corresponding to the first radio frequency signal and the transmitting device of the first radio frequency signal.

[0047] Specifically, if the communication standard supported by the co-managed relay device includes the first communication standard, and the transmitting device of the first radio frequency signal is the communication device corresponding to the host cell (which can be called the first host cell) of the co-managed relay device in the first communication standard, it can be determined that the first radio frequency signal is the radio frequency signal transmitted by the communication device corresponding to the host cell in the communication standard supported by the co-managed relay device. Therefore, it can be determined that the first radio frequency signal is the radio frequency signal that the co-managed relay device supports for forwarding, and the first radio frequency signal can be forwarded through step 302.

[0048] If the communication standard supported by the co-managed relay device does not include the first communication standard, or if the transmitting device of the first radio frequency signal is not the communication device corresponding to the first host cell, it can be determined that the first radio frequency signal is not the radio frequency signal transmitted by the communication device corresponding to the host cell in the communication standard supported by the co-managed relay device. Therefore, it can be determined that the first radio frequency signal is not the radio frequency signal that the co-managed relay device supports for forwarding. The co-managed relay device may discard or not forward the first radio frequency signal.

[0049] Step 302: When at least two communication standards include the first communication standard corresponding to the first radio frequency signal and the transmitting device of the first radio frequency signal is the communication device corresponding to the first host cell, the first radio frequency signal is forwarded according to the first radio frequency forwarding control information corresponding to the first communication standard.

[0050] The first host cell is the host cell of the relay device in the first communication standard.

[0051] As can be seen from the foregoing, the relay device can forward radio frequency signals according to the radio frequency forwarding control information. In this embodiment of the application, the co-managed relay device can support the forwarding of radio frequency signals of multiple communication standards. Therefore, for the multiple communication standards it supports, the radio frequency forwarding control information corresponding to each communication standard can be obtained to forward the radio frequency signals of the corresponding communication standard.

[0052] In some embodiments, different communication standards can share a set of radio frequency forwarding control information. In these embodiments, the radio frequency forwarding control information corresponding to different communication standards is the same.

[0053] In other embodiments, different communication standards can each correspond to a set of radio frequency forwarding control information, meaning that the radio frequency forwarding control information corresponding to different communication standards can be independent of each other. In these embodiments, the radio frequency forwarding control information corresponding to different communication standards may be the same or different, depending on the actual situation, and this application does not limit this.

[0054] In step 302, the first radio frequency signal is a radio frequency signal that the co-managed relay device supports for forwarding. Therefore, the co-managed relay device can forward the first radio frequency signal. In specific implementation, since the first radio frequency signal is a radio frequency signal of the first communication standard, the first radio frequency signal can be amplified and forwarded according to the radio frequency forwarding control information corresponding to the first communication standard (referred to as the first radio frequency forwarding control information).

[0055] In this embodiment, the relay device can support the forwarding of radio frequency signals from multiple communication standards. This means that a single relay device can forward radio frequency signals from multiple communication standards, thereby reducing deployment and maintenance costs, and ultimately lowering the overall management cost. For a relay device supporting the forwarding of radio frequency signals from multiple communication standards, upon receiving a first radio frequency signal, it can first determine whether the first communication standard corresponding to the first radio frequency signal belongs to one of its supported communication standards, and whether the transmitting device of the first radio frequency signal is the communication device corresponding to the host cell of the first communication standard. If both are true, it indicates that the first radio frequency signal is a supported radio frequency signal. Based on the radio frequency forwarding control information corresponding to the first communication standard, the first radio frequency signal can be forwarded. This ensures reliable forwarding of the radio frequency signal and guarantees the radio frequency forwarding accuracy of the relay device supporting the forwarding of radio frequency signals from multiple communication standards.

[0056] This application does not limit the method of obtaining radio frequency forwarding control information. In this application, the co-managed relay device may, but is not limited to, obtaining radio frequency forwarding control information corresponding to a certain communication standard from the following devices:

[0057] The shared relay equipment is the base station to which the host cell of this communication standard belongs;

[0058] First network-side device.

[0059] Based on this, in some embodiments, the first radio frequency forwarding control information may include at least one of the following:

[0060] The first sub-radio frequency forwarding control information sent by the first base station to which the first host cell belongs;

[0061] The first network-side device sends the second sub-radio frequency forwarding control information corresponding to the first communication standard; wherein, the first network-side device supports monitoring and management of the radio frequency forwarding control information of different communication standards of the relay device.

[0062] It is understood that for radio frequency forwarding control information corresponding to other communication standards, the same logic as that used for the first radio frequency forwarding control information can be used to obtain it. In other words, for radio frequency forwarding control information of different communication standards, it can include at least one of the following: radio frequency forwarding control information sent by the home base station of the corresponding host cell; and the corresponding radio frequency forwarding control information sent by the first network side device.

[0063] The following is a detailed description of the first network-side equipment.

[0064] In this embodiment, a relay device management unit can be introduced for co-managed relay devices to monitor and manage radio frequency forwarding control information for different communication standards supported by the co-managed relay device. Furthermore, the relay device management unit can also store and display the host cell information of the co-managed relay device for different communication standards. Therefore, the relay device management unit can also be called a relay device visual and manageable unit. Further, when the relay device exhibits NCR (Non-Commercial Relay) behavior, the relay device visual and manageable unit can be called an NCR visual and manageable unit.

[0065] The co-managed relay equipment and the relay equipment management unit can have a one-to-one correspondence or a many-to-one correspondence. That is to say, different co-managed relay equipment can monitor and manage their radio frequency forwarding control information through different relay equipment management units, or they can monitor and manage their radio frequency forwarding control information through the same relay equipment management unit. The specific method can be determined according to the actual situation, and this application embodiment does not limit this.

[0066] The embodiments of this application do not limit the specific form of the relay equipment management unit, which can be a physical device or a functional device.

[0067] The first network-side device is determined based on the relay device management unit. The relationship between the first network-side device and the relay device management unit can differ depending on the form of the relay device management unit, as detailed below:

[0068] When the relay equipment management unit is a physical device, the first network-side device is the relay equipment management unit. In this case, the first network-side device can be set up independently or integrated into other physical devices. Optionally, the first network-side device can be integrated into the network management system corresponding to the host base station of the relay equipment. In this way, the co-managed relay equipment can be uniformly managed through the network management system corresponding to the host base station of the co-managed relay equipment, which can improve the management centralization of the co-managed relay equipment and thus improve the management efficiency of the co-managed relay equipment.

[0069] When the relay equipment management unit is a functional entity, the first network-side device can be an entity device that integrates the relay equipment management unit. Optionally, the first network-side device can be the network management system corresponding to the host base station of the relay equipment. In this way, the co-managed relay equipment can be uniformly managed through the network management system corresponding to the host base station of the co-managed relay equipment, which can improve the management centralization of the co-managed relay equipment and thus improve the management efficiency of the co-managed relay equipment.

[0070] Furthermore, the embodiments of this application do not limit the method by which the above-mentioned device sends radio frequency forwarding control information to the co-managed relay device. In some embodiments, the above-mentioned device can directly interact with the co-managed relay device to send radio frequency forwarding control information. In other embodiments, the above-mentioned device can send radio frequency forwarding control information to the co-managed relay device through the host base station of the co-managed relay device. In these embodiments, the co-managed relay device can obtain radio frequency forwarding control information from the host base station through the Data Radio Bearer (DRB) channel.

[0071] It is worth noting that, in the embodiments of this application, the DRB channel between the co-managed relay equipment and the host base station may, but is not limited to, the following methods:

[0072] Method 1: A shared DRB channel is set up between the co-managed relay equipment and the host base station to transmit the radio frequency forwarding control information corresponding to each communication standard. That is, the radio frequency forwarding control information corresponding to each communication standard is transmitted through the same DRB channel.

[0073] Method 2: A dedicated DRB channel corresponding to at least two communication standards is set up between the co-managed relay equipment and the host base station. The dedicated DRB channel corresponding to each communication standard is used to transmit the radio frequency forwarding control information corresponding to that communication standard. That is, the radio frequency forwarding control information corresponding to each communication standard is transmitted through its own independent dedicated DRB channel.

[0074] Of course, in other implementations, at least some of the two communication standards can share a single DRB channel to transmit radio frequency forwarding control information, while the other two use their own independent DRB channels to transmit radio frequency forwarding control information. The specific implementation can be determined according to the actual situation, and this application does not limit this.

[0075] Based on this, in some embodiments, before forwarding the first radio frequency signal according to the first radio frequency forwarding control information corresponding to the first communication standard, the method further includes:

[0076] Based on the first data wireless bearer channel, a first message carrying radio frequency forwarding control information is received from the host base station of the relay device;

[0077] Based on the first message, obtain the first radio frequency forwarding control information;

[0078] The first data wireless bearer channel is: a dedicated data wireless bearer channel for the first communication standard; or a shared data wireless bearer channel for at least two communication standards.

[0079] In other words, for the first radio frequency forwarding control information corresponding to the first communication standard, the co-managed relay device can receive the first message from the host base station through the dedicated DRB channel of the first communication standard or the shared DRB channel of different communication standards.

[0080] In this application embodiment, the message used to carry radio frequency forwarding control information is referred to as the first message. However, this application embodiment does not limit the specific form of the first message. It can be DCI or other messages, and the specific form can be determined according to the actual situation.

[0081] It should be noted that for a shared DRB channel for different communication standards, since this DRB channel can be used to transmit radio frequency forwarding control information for multiple communication standards, in order for the relay device to accurately distinguish the communication standard corresponding to the radio frequency forwarding control information carried in the first message, that is, to distinguish which communication standard's radio frequency forwarding control information is carried in the first message, when transmitting the first message through the shared DRB channel, the first message can satisfy at least one of the following:

[0082] The information format of the radio frequency forwarding control information carried in the first message varies depending on the communication standard.

[0083] The first message also carries the communication standard identifier corresponding to the radio frequency forwarding control information.

[0084] When the information formats of the radio frequency forwarding control information corresponding to different communication standards carried in the first message are different, the co-managed relay equipment can distinguish the communication standard corresponding to the radio frequency forwarding control information based on the information format of the radio frequency forwarding control information in the first message. When the first message carries both radio frequency forwarding control information and its corresponding communication standard identifier, the co-managed relay equipment can identify the corresponding communication standard based on the communication standard identifier of the radio frequency forwarding control information in the first message. In this way, the radio frequency forwarding control information carried in the first message transmitted through the shared DRB channel and its corresponding communication standard can be accurately distinguished, thereby improving the reliability of radio frequency forwarding of the co-managed relay equipment.

[0085] Based on this, in some embodiments, obtaining first radio frequency forwarding control information according to the first message includes:

[0086] If the first message satisfies the first condition, the radio frequency forwarding control information carried in the first message is determined to be the first radio frequency forwarding control information;

[0087] The first condition includes at least one of the following:

[0088] The channel type of the first data radio bearer channel used for transmitting the first message is a dedicated data radio bearer channel of the first communication standard;

[0089] The information format of the radio frequency forwarding control information carried in the first message matches the information format of the radio frequency forwarding control information corresponding to the first communication standard.

[0090] The communication standard identifier corresponding to the radio frequency forwarding control information carried in the first message matches the communication standard identifier corresponding to the first communication standard.

[0091] In practice, after receiving the first message, the co-managed relay device can identify the communication standard corresponding to the radio frequency forwarding control information carried in the first message through at least one of the following methods:

[0092] The channel type of the DRB channel carrying the first message;

[0093] The information format of the radio frequency forwarding control information in the first message;

[0094] The communication standard identifier corresponding to the radio frequency forwarding control information in the first message.

[0095] Specifically, if the channel type of the DRB channel carrying the first message is a dedicated DRB channel of a certain communication standard, then the communication standard corresponding to the dedicated DRB channel can be determined, that is, the communication standard corresponding to the radio frequency forwarding control information carried in the first message.

[0096] If the information format of the radio frequency forwarding control information in the first message matches the information format of the radio frequency forwarding control information of a certain communication standard, then the communication standard can be determined, that is, the communication standard corresponding to the radio frequency forwarding control information carried in the first message.

[0097] If the communication standard identifier corresponding to the radio frequency forwarding control information in the first message is the communication standard identifier of a certain communication standard, then it can be determined that the communication standard is the communication standard corresponding to the radio frequency forwarding control information carried in the first message.

[0098] In this way, the co-managed relay equipment can accurately obtain the radio frequency forwarding control information and its corresponding communication standard carried in the first message, and thus forward the radio frequency signal of the corresponding communication standard according to the radio frequency forwarding control information, thereby improving the reliability of the radio frequency forwarding of the co-managed relay equipment.

[0099] It should be noted that, for the scheme where the home base station of the host cell sends radio frequency forwarding control information to the co-managed relay equipment through the host base station of the co-managed relay equipment, the embodiments of this application do not limit the interaction method of radio frequency forwarding control information between the home base station and the host base station. In some embodiments, when the first radio frequency forwarding control information includes the first sub-radio frequency forwarding control information sent by the first base station to which the first host cell belongs, the host base station can obtain the first sub-radio frequency forwarding control information from the first base station through the relay equipment management link between the host base station and the first base station.

[0100] In these embodiments, a relay device management link can be established between the home base station and the host base station for transmitting radio frequency forwarding control information. The establishment of the relay device management link can be found in the relevant description below, and will not be described here.

[0101] In practice, the home base station can send radio frequency forwarding control information to the host base station through the relay equipment management link between the home base station and the host base station. This enables the host base station to send a first message carrying the radio frequency forwarding control information to the co-managed relay equipment, thereby realizing the transmission of the radio frequency forwarding control information.

[0102] The following explains how to determine the host cell for co-managed relay equipment in each communication standard.

[0103] It is understandable that, in practical applications, the first communication standard may be any of the multiple communication standards supported by the managed relay equipment.

[0104] As described above, a co-managed relay device can be hosted on a specific communication standard and connected to a specific cell of a base station within that standard. Within this communication standard, the cell to which the co-managed relay device is connected can be considered its host cell. Therefore, in the case where the first communication standard is the one on which the co-managed relay device is hosted, the cell of the first communication standard to which the co-managed relay device is connected can be directly considered its first host cell.

[0105] In some embodiments, when the first communication standard is a communication standard other than the communication standard corresponding to the host base station of the relay device among at least two communication standards, before forwarding the first radio frequency signal according to the first radio frequency forwarding control information corresponding to the first communication standard, the method further includes:

[0106] The system receives a first inter-system measurement configuration corresponding to a first communication standard from the host base station; wherein the first inter-system measurement configuration includes a first inter-system measurement frequency point corresponding to the first communication standard; the first inter-system measurement frequency point is determined based on the radio frequency forwarding frequency point of the first communication standard supported by the relay device and the inter-system frequency point of the first neighboring cell; the first neighboring cell is the neighboring cell of the host base station corresponding to the first communication standard;

[0107] Based on the first inter-system measurement configuration, perform the first inter-system measurement and obtain the first inter-system measurement report corresponding to the first communication standard;

[0108] Send a first inter-system measurement report to the host base station; wherein, the first inter-system measurement report is used by the host base station to determine the first host cell.

[0109] In these embodiments, when the first communication standard is a communication standard other than the managed communication standard of the co-managed relay device, the first host cell of the first communication standard of the co-managed relay device can be obtained by using a heterogeneous measurement method. For specific implementation, please refer to the relevant description below, which will not be described here.

[0110] In this way, the host cell of each communication standard supported by the co-managed relay device can be obtained, which enables the co-managed relay device to forward the radio frequency signals sent by the communication device corresponding to the host cell, thereby improving the radio frequency forwarding capability of the co-managed relay device and reducing the management cost of the relay device.

[0111] In some embodiments, after determining the host cell of the co-managed relay device in each communication standard, the host cell information can be reported to the relay device management unit so that the relay device management unit can manage the forwarding of radio frequency signals for each communication standard.

[0112] See Figure 4 , Figure 4 This is the second flowchart illustrating the management method for relay devices provided in the embodiments of this application. Figure 4 The management method for relay equipment shown can be applied to the host base station of co-managed relay equipment. In specific implementation, Figure 4 The management method of the relay equipment shown can be executed by the host base station, or by components of the host base station, such as the host base station's processor, chip, or chip system, or by logic modules or software that implement all or part of the host base station's functions.

[0113] like Figure 4 As shown, the management method for relay equipment includes, but is not limited to, the following steps:

[0114] Step 401: In response to the access of the relay device, if the relay device is found to be forwarding a radio frequency signal that supports the second communication standard, a second inter-system measurement configuration corresponding to the second communication standard is sent to the relay device; wherein, the second communication standard is any communication standard other than the communication standard corresponding to the host base station among at least two communication standards; the second inter-system measurement configuration includes a second inter-system measurement frequency point corresponding to the second communication standard; the second inter-system measurement frequency point is determined based on the radio frequency forwarding frequency point of the second communication standard supported by the relay device and the inter-system frequency point of the second neighboring cell; the second neighboring cell is the neighboring cell of the host base station corresponding to the second communication standard.

[0115] In this embodiment, a capability item can be introduced for the relay device: radio frequency (RF) forwarding capability. The RF forwarding capability of the relay device can indicate which communication standards' RF signals the relay device supports for forwarding. Furthermore, it can also indicate the RF forwarding frequency points of each communication standard supported by the relay device. Specifically, the RF forwarding capability of the relay device can, but is not limited to, indicating the RF forwarding frequency points of a certain communication standard supported by the relay device through the following information: the RF forwarding frequency band of the communication standard supported by the relay device; the RF forwarding bandwidth and center frequency point of the communication standard supported by the relay device.

[0116] In response to the access of the relay device, the host base station can first obtain the radio frequency forwarding capability of the relay device to obtain the communication standard supported by the relay device and the corresponding radio frequency forwarding frequency. This application embodiment does not limit the method by which the host base station obtains the radio frequency forwarding capability of the relay device. In some embodiments, before sending the second heterogeneous system measurement configuration corresponding to the second communication standard to the relay device, the method may further include:

[0117] Obtain the radio frequency forwarding frequency points of the second communication standard supported by the relay device from the network management system corresponding to the host base station;

[0118] Based on the second message sent by the relay device, which indicates the radio frequency forwarding capability of the relay device corresponding to the second communication standard, the radio frequency forwarding frequency point of the second communication standard supported by the relay device is obtained.

[0119] In other words, the host base station can obtain the radio frequency forwarding capability of the access relay equipment through, but is not limited to, the following methods:

[0120] Method 1: Obtain the radio frequency forwarding capability of the relay equipment from the network management system of the host base station. In this method, the radio frequency forwarding capability of the relay equipment can be pre-configured in the network management system of the host base station according to the network plan. Furthermore, this configuration can be done manually, but it is not limited to this.

[0121] Method 2: The host base station can obtain the radio frequency forwarding capability of the relay device through interaction with the relay device. Specifically, the relay device can indicate its radio frequency forwarding capability through a second message. This application does not limit the specific form of the second message. In some implementations, the second message can be a standard UE capability message, such as by finding specific protocol fields or combinations of fields in the standard UE capabilities and combining them with a private agreement between the base station and the relay device to carry the relay device's radio frequency forwarding capability. In other implementations, the second message can be a custom message between the base station and the relay device; that is, the radio frequency forwarding capability of the relay device can be obtained through a custom message between the base station and the relay device.

[0122] This can enrich the ways in which the host base station obtains the radio frequency forwarding capability of the relay equipment, and improve the flexibility of the host base station in obtaining the radio frequency forwarding capability of the relay equipment.

[0123] It is understood that in practical applications, the access relay device may support the forwarding of radio frequency signals of only one communication standard, or it may support the forwarding of radio frequency signals of multiple communication standards. However, the embodiments of this application mainly focus on co-managed relay devices that support the forwarding of radio frequency signals of multiple communication standards. Therefore, it is assumed that the access relay device is a co-managed relay device and that it supports the forwarding of radio frequency signals of at least the second communication standard. Then, steps 401 to 403 describe the determination of the host cell (referred to as the second host cell) of the co-managed relay device in the second communication standard, so that the co-managed relay device can forward the radio frequency signals sent by the communication device corresponding to the second host cell.

[0124] It should be noted that if a co-managed relay device supports the forwarding of radio frequency signals of three or more communication standards, the second communication standard can be understood as any communication standard supported by the co-managed relay device other than the managed communication standard. That is, for any communication standard other than the managed communication standard of the co-managed relay device, the same method of determining the second host cell can be used to determine the host cell of the co-managed relay device in this communication standard.

[0125] In step 401, the forwarding of radio frequency signals supported by the co-managed relay device for the second communication standard is obtained, and the host cell of the co-managed relay device in the second communication standard can be determined by using a heterogeneous system measurement method.

[0126] In practice, the host base station can first obtain the inter-system frequency points of the neighboring cells of the second communication standard (which can be referred to as the second neighboring cells), as well as the radio frequency forwarding frequency points of the second communication standard supported by the relay equipment, so as to determine the inter-system measurement frequency point of the second communication standard (which can be referred to as the second inter-system measurement frequency point) based on the above two types of frequency points. In practice, the inter-system frequency points of the second neighboring cells covered by the radio frequency forwarding frequency points of the second communication standard supported by the relay equipment can be used as the second inter-system measurement frequency points.

[0127] The second neighboring cell may include a cell that is adjacent to or has signal coverage with the host base station in the second communication standard. It may include one or more cells. That is, in this embodiment of the application, if a cell is adjacent to or has signal coverage with the host base station, the cell may be regarded as a neighboring cell of the host base station.

[0128] After determining the second inter-system measurement frequency point, an inter-system measurement configuration (which can be called the second inter-system measurement configuration) corresponding to the second communication standard can be sent to the co-managed relay equipment. The second inter-system measurement frequency point is carried through the second inter-system measurement configuration, so that the co-managed relay equipment can perform inter-system measurement (which can be called the second inter-system measurement) corresponding to the second communication standard based on the second inter-system measurement configuration, and obtain an inter-system measurement report corresponding to the second communication standard.

[0129] Step 402: Receive the second inter-system measurement report sent by the relay device; wherein the second inter-system measurement report is an inter-system measurement report sent by the relay device in response to the second inter-system measurement configuration.

[0130] It should be noted that, in some embodiments, the second inter-system measurement configuration can be a periodic measurement configuration or an event-based measurement configuration. In these embodiments, it can be understood that, in response to the second inter-system measurement configuration, the managed relay device can perform at least one inter-system measurement, thereby obtaining at least one inter-system measurement report corresponding to the second communication standard. Based on this, the second inter-system measurement report in step 402 can be understood as: an inter-system measurement report obtained by the managed relay device performing one inter-system measurement in response to the second inter-system measurement configuration.

[0131] Step 403: Based on the second inter-system measurement report, determine the second host cell of the second communication standard for the relay device; wherein, the relay device supports forwarding the radio frequency signals sent by the communication device corresponding to the second host cell.

[0132] The second inter-system measurement report is obtained by performing inter-system measurements based on the second inter-system measurement frequency. Based on this, the second host cell determined according to the second inter-system report can be a cell in the second neighboring cell, but this does not limit the relationship between the second host cell and the second neighboring cell. The second host cell may include one or more cells.

[0133] In this embodiment, the inter-system measurement report may include at least one Physical Cell Identifier (PCI). In some embodiments, the host base station may directly use the cell in the second communication standard that corresponds to the PCI in the second inter-system measurement report as the second host cell. In other embodiments, the host base station may first determine the Global Cell Identifier (CGI, which may be referred to as the first CGI) based on the PCI in the second inter-system measurement report, and then determine the second host cell based on the first CGI. For details, please refer to the relevant description below, which will not be described in detail here.

[0134] In this embodiment, a heterogeneous measurement method can be used to determine the host cell of the co-managed relay device in other communication standards besides the managed communication standard, thereby achieving accurate determination of the host cell of the co-managed relay device. This enables the co-managed relay device to forward the radio frequency signals sent by the communication device corresponding to the host cell, improving the radio frequency forwarding capability of the co-managed relay device and reducing the management cost of the relay device.

[0135] In some embodiments, determining the second host cell of the second communication standard based on the second inter-system measurement report includes:

[0136] The first global cell identifier is determined based on the physical cell identifier in the second heterogeneous system measurement report;

[0137] The cell corresponding to the first global cell identifier is identified as the candidate cell for the relay device corresponding to the second communication standard;

[0138] Based on the cell information of the second neighboring cell and candidate cells, the second host cell of the relay equipment in the second communication standard is determined; wherein, the cell information includes: the global cell identifier of the cell, the base station to which the cell belongs, the transmission link information between the base station to which the cell belongs and the host base station, and the deployment capability information of the relay equipment in the cell.

[0139] In these embodiments, after the host base station determines the first CGI based on the PCI in the second inter-system measurement report, it first identifies the cell corresponding to the first CGI as a candidate cell for the co-managed relay device in the second communication standard. Then, based on the cell information of the second neighboring cell, it filters the candidate cells to obtain the second host cell. In this way, compared to directly identifying the cell corresponding to the first CGI as the second host cell after determining the first CGI, the accuracy of determining the second host cell can be improved.

[0140] Further, the first global cell identifier is determined based on the physical cell identifier in the second heterogeneous system measurement report, and may include any of the following:

[0141] Based on the physical cell identifier in the second heterogeneous system measurement report, the cell relationship configuration is queried to obtain the first global identifier; wherein, the cell relationship configuration includes the correspondence between the physical cell identifier and the global cell identifier;

[0142] Send a global cell identifier measurement configuration corresponding to the physical cell identifier in the second inter-system measurement report to the first device; determine the global cell identifier in the global cell identifier measurement report sent by the first device as the first global identifier; wherein, the first device is a relay device or a terminal device corresponding to the relay device; the global cell identifier measurement report is a global cell identifier measurement report sent by the first device in response to the global cell identifier measurement configuration.

[0143] In other words, in this embodiment of the application, the host base station can determine the CGI based on the PCI in the inter-system measurement report in the following way:

[0144] Method 1: The host base station can obtain the cell configuration relationship in advance, and then query the CGI corresponding to the PCI in the inter-system measurement report from the cell relationship configuration;

[0145] Method 2: The host base station can send a CGI measurement configuration to the first device based on the PCI in the inter-system measurement report, triggering the first device to perform CGI measurement according to the CGI measurement configuration, obtain the first CGI, and send the first CGI along with the CGI measurement report to the host base station, so that the host base station can obtain the first CGI from the CGI measurement report.

[0146] The first device can be a co-managed relay device or a UE under a co-managed relay device. In other words, the above CGI measurement can be performed by a co-managed relay device or a UE under a co-managed relay device.

[0147] This can enrich the ways to obtain the first CGI and improve the flexibility of obtaining the first CGI.

[0148] Furthermore, based on the cell information of the second neighboring cell and candidate cells, the second host cell of the relay equipment in the second communication standard is determined, including:

[0149] Based on the global cell identifier of the candidate cell, obtain the cell information of the candidate cell from the cell information of the second neighboring cell;

[0150] If the transmission link information in the candidate cell's cell information indicates that there is a transmission link between the target base station and the host base station to which the candidate cell belongs, and the relay equipment deployment capability information indicates that the candidate cell supports the co-managed deployment of relay equipment, then the candidate cell will be determined as the second host cell of the relay equipment in the second communication standard.

[0151] In this embodiment, the decision to designate a candidate cell as a second host cell can be made by combining the candidate cell's cell information. Specifically, the decision can be made by combining the transmission link information between the target base station and the host base station to which the candidate cell belongs, as well as the relay equipment deployment capability information of the candidate cell. The transmission link information between the target base station and the host base station can be used to indicate whether a transmission link exists between them; the relay equipment deployment capability information of the candidate cell can be used to indicate whether the candidate cell supports co-managed deployment of relay equipment.

[0152] In practice, if the transmission link information between the target base station and the host base station of the candidate cell indicates that a transmission link exists, and the relay equipment deployment capability information of the candidate cell indicates that the candidate cell supports the co-managed deployment of relay equipment, it means that the target base station to which this candidate cell belongs has the conditions for co-managing relay equipment with the host base station, and this candidate cell can be used as the second host cell. Conversely, if the transmission link information between the target base station and the host base station of the candidate cell indicates that a transmission link does not exist, or if the relay equipment deployment capability information of the candidate cell indicates that the candidate cell does not support the co-managed deployment of relay equipment, it means that the target base station to which this candidate cell belongs does not have the conditions for co-managing relay equipment with the host base station, and this candidate cell can be abandoned as the second host cell.

[0153] In this way, it can be ensured that the designated second host cell has the conditions for the deployment of co-managed relay equipment, thereby enabling the co-managed relay equipment to forward the radio frequency signals sent by the communication equipment corresponding to the second host cell, and thus enabling the co-managed relay equipment to support the forwarding of radio frequency signals of the second communication standard, thereby improving the radio frequency forwarding capability of the co-managed relay equipment.

[0154] It should be noted that in practical applications, the signal coverage of a cell may change, and the radio frequency forwarding points supported by the co-managed relay equipment may also change. These changes may cause changes in the host cell of the co-managed relay equipment. Therefore, in some embodiments, after determining the second host cell of the relay equipment for the second communication standard based on the second inter-system measurement report, the method may further include:

[0155] Receive a third inter-system measurement report; wherein the physical cell identifier in the third inter-system measurement report is different from the physical cell identifier in the second inter-system measurement report; the third inter-system measurement report is an inter-system measurement report sent by the relay device in response to the second inter-system measurement configuration, or the third inter-system measurement report is an inter-system measurement report sent by the relay device in response to the third inter-system measurement configuration; the third inter-system measurement configuration is a new inter-system measurement configuration sent by the host base station to the relay device in response to a change in the radio frequency forwarding frequency of the second communication standard supported by the relay device; the third inter-system measurement frequency in the third inter-system measurement configuration is different from the second inter-system measurement frequency.

[0156] According to the third heterogeneous system measurement report, the relay equipment is updated in the second host cell of the second communication standard.

[0157] In this embodiment, for each communication standard, the host base station can determine whether the host cell of the relay device has changed for that communication standard by comparing the PCI in the newly received inter-system measurement report with the PCI in the historically received inter-system measurement reports. Specifically, if the two PCIs are the same, it can be determined that the host cell of the relay device has not changed for that communication standard, and the host cell can remain unchanged; if the two PCIs are different, it can be determined that the host cell of the relay device has changed for that communication standard, and the host cell is re-determined based on the new inter-system measurement report to update the host cell.

[0158] In this embodiment, the PCI in the third inter-system measurement report is different from the PCI in the first inter-system measurement report, indicating that the co-managed relay device has changed the second host cell of the second communication standard. Therefore, the second host cell can be updated according to the third inter-system measurement report. The specific implementation logic is the same as that for determining the second host cell according to the first inter-system measurement report. To avoid repetition, it will not be described again.

[0159] In this embodiment, the third inter-system measurement report may be an inter-system measurement report sent by the co-managed relay device in response to the second inter-system measurement configuration, or it may be an inter-system measurement report sent by the co-managed relay device in response to the third inter-system measurement configuration.

[0160] It should be noted that both the second and third inter-system measurement configurations are inter-system measurement configurations corresponding to the second communication standard sent by the host base station to the co-managed relay equipment. The difference between the two is that the inter-system measurement frequency points carried in the inter-system measurement configurations are different.

[0161] In practice, the host base station can monitor the radio frequency forwarding capability of the co-managed relay equipment. Upon detecting a change in the radio frequency forwarding frequency of the second communication standard supported by the co-managed relay equipment, it can determine whether the inter-system frequency of the second neighboring cell covered by the changed radio frequency forwarding frequency has changed. If a change has occurred, the host base station can issue a new inter-system measurement configuration corresponding to the second communication standard, i.e., a third inter-system measurement configuration, to the co-managed relay equipment. If no change has occurred, the host base station will not update the inter-system measurement configuration of the co-managed relay equipment corresponding to the second communication standard.

[0162] Furthermore, as mentioned above, the inter-system measurement configuration sent by the host base station to the co-managed relay equipment can be a periodic measurement configuration or an event-based measurement configuration. In response to this inter-system measurement configuration, the co-managed relay equipment can perform multiple inter-system measurements. If the signal coverage area of ​​the second neighboring cell changes during this process, it may cause a change in the measured PCI, resulting in different PCI values ​​in different inter-system measurement reports sent by the co-managed relay equipment in response to the same inter-system measurement configuration.

[0163] Based on the above, it can be understood that the third inter-system measurement report is a scenario in which the radio frequency forwarding frequency of the second communication standard supported by the co-managed relay device changes in response to the inter-system measurement report sent by the co-managed relay device in response to the inter-system measurement report sent by the second inter-system measurement configuration; the third inter-system measurement report is a scenario in which the signal coverage of the second neighboring cell changes in response to the inter-system measurement report sent by the co-managed relay device in response to the second inter-system measurement configuration.

[0164] Through the above embodiments, the host cell of the co-managed relay equipment can be updated in a timely manner, thereby further improving the accuracy of host cell determination and thus improving the radio frequency forwarding reliability of the co-managed relay equipment.

[0165] As described above, the radio frequency forwarding control information for each communication standard can be controlled by the host cell. Specifically, the host cell can send the corresponding radio frequency forwarding control information to the host base station through its affiliated base station, and then forward the corresponding radio frequency forwarding control information to the co-managed relay equipment through the host base station, so that the co-managed relay equipment can forward the radio frequency signal of that communication standard based on the radio frequency forwarding control information corresponding to that communication standard. In some embodiments, the second host cell includes the first cell;

[0166] Based on the second inter-system measurement report, after determining the relay equipment in the second host cell of the second communication standard, the method further includes:

[0167] Establish a first relay equipment management link between the host base station and the second base station to which the first cell belongs;

[0168] The relay device receives second radio frequency forwarding control information sent by the second base station through the first relay device management link; wherein, the second radio frequency forwarding control information is used by the relay device to forward radio frequency signals of the second communication standard;

[0169] According to the second radio frequency forwarding control information, a first message carrying radio frequency forwarding control information is sent to the relay device. The first message is used by the relay device to forward radio frequency signals according to the radio frequency forwarding control information in the first message.

[0170] In these embodiments, a relay equipment management link can be established between the home base station of the host cell and the host base station to transmit radio frequency forwarding control information through the relay equipment management link, thereby improving the transmission reliability of radio frequency forwarding control information.

[0171] This application does not limit the method of establishing the relay device management link. In some embodiments, establishing a first relay device management link between the host base station and the second base station to which the first cell belongs includes:

[0172] A relay device management link establishment request is sent to the second base station to which the first cell belongs; wherein, the relay device management link establishment request is used to request the establishment of a first relay device management link between the second base station and the host base station; the relay device management link establishment request includes: the identity information of the relay device, the global cell identifier of the first cell, and the first identifier of the host base station used to identify the first relay device management link;

[0173] The system receives a relay device management link establishment response sent by the second base station in response to the relay device management link establishment request; wherein the link establishment response includes a second identifier of the second base station used to identify the first relay device management link.

[0174] In practice, after the host base station determines that the first cell will be used as the host cell for the second communication standard, it can send a relay device management link establishment request to the second base station to which the first cell belongs. This request requests the establishment of a relay device management link (which can be referred to as the first relay device management link) between the second base station and the host base station. This link is used to transmit the radio frequency forwarding control information for the second communication standard determined by the first cell. The relay device management link establishment request may, but is not limited to, carry the relay device's identity information, the first cell's CGI, and the host base station's first identifier used to identify the first relay device management link. The first identifier can be understood as the host base station-side channel identifier for the first relay device management link.

[0175] After receiving the relay device management link establishment request, the second base station can maintain the relay device's identity information and the host base station's side channel identifier in the first cell, and allocate a second identifier for the second base station to identify the first relay device management link. Then, it sends the second identifier in the relay device management link establishment response back to the host base station. The second identifier can be understood as the second base station's side channel identifier for the first relay device management link.

[0176] If the above process is successful, the management link for the first relay device is successfully established. This provides a solution for establishing relay device management links, thereby improving the reliability of radio frequency forwarding control information transmission.

[0177] In some embodiments, sending a first message carrying radio frequency forwarding control information to a relay device according to the second radio frequency forwarding control information may include:

[0178] Based on the second radio frequency forwarding control information, a first message carrying the radio frequency forwarding control information is sent to the relay device through the second data radio bearer channel;

[0179] The second data radio bearer channel is: a dedicated data radio bearer channel for the second communication standard; or a shared data radio bearer channel for at least two communication standards.

[0180] It should be noted that the specific implementation logic of this embodiment is the same as the aforementioned implementation logic of "receiving the first message based on the first DRB channel". For details, please refer to the aforementioned relevant description, which will not be repeated here.

[0181] As can be seen from the foregoing, the second host cell may change. In some embodiments, when the second host cell changes, and the changed second host cell does not include the first cell, but a new second cell is added, after establishing the first relay device management link between the host base station and the second base station to which the first cell belongs, the method further includes:

[0182] Release the management link of the first relay device;

[0183] Establish a second relay equipment management link between the host base station and the third base station to which the second cell belongs;

[0184] The second relay device receives third radio frequency forwarding control information sent by the third base station through the second relay device management link; wherein, the third radio frequency forwarding control information is used by the relay device to perform the forwarding of radio frequency signals of the second communication standard.

[0185] Based on the third radio frequency forwarding control information, the first message is sent to the relay device.

[0186] In this embodiment, since the modified second host cell does not include the first cell and a new second cell is added, the first relay equipment management link between the second base station to which the first base station belongs and the host base station can be released in a timely manner, and a second relay equipment management link can be established between the third base station to which the second cell belongs and the host base station, so as to improve the system resource utilization while ensuring the reliability of radio frequency forwarding of the co-managed relay equipment.

[0187] The establishment logic of the second relay device management link can be the same as that of the first relay device management link. For details, please refer to the aforementioned descriptions, which will not be described here.

[0188] Regarding the release of the first relay device management link, this application embodiment does not limit the method of releasing the relay device management link. In some embodiments, releasing the first relay device management link may include:

[0189] Send a relay device management link release command to the second base station; wherein, the relay device management link release command is used to instruct the release of the first relay device management link; the relay device management link release command includes the identity information of the relay device, a first identifier of the host base station used to identify the first relay device management link, and a second identifier of the second base station used to identify the first relay device management link;

[0190] Receive the relay device management link release completion indication sent by the second base station in response to the relay device management link release command.

[0191] In this embodiment, the host base station can send a relay device management link release command to the second base station to which the first cell belongs, thereby releasing the first relay device management link in a standardized manner. The relay device management link release command may, but is not limited to, carry the identity information of the relay device, the host base station-side identifier and the second base station-side identifier of the first relay device management link.

[0192] After receiving the relay device management link release command, the second base station can clear the relevant information of the relay device, complete the release of the first relay device management link, and reply with a relay device management link release completion indication.

[0193] This provides a solution for releasing the management link of relay devices, thereby improving the utilization rate of system resources.

[0194] In this embodiment of the application, the host base station can obtain cell information of each neighboring cell. The cell information may include at least one of the following: the inter-system frequency of the cell; cell relationship configuration; the global cell identifier of the cell; the base station to which the cell belongs; the transmission link information between the base station to which the cell belongs and the host base station; and the relay equipment deployment capability information of the cell.

[0195] Based on this, in some embodiments, before sending the second inter-system measurement configuration corresponding to the second communication standard to the relay device, the method further includes:

[0196] Based on the cell information of the second neighboring cell, obtain the inter-system frequency points of the second neighboring cell;

[0197] The community information is obtained through any of the following methods:

[0198] Obtain from the network management system corresponding to the host base station;

[0199] It is obtained from the base station of the second neighboring cell through the communication link between the host base station and the base station to which the second neighboring cell belongs.

[0200] In this embodiment, the inter-system frequency point of the second neighboring cell can be obtained from the cell information of the second neighboring cell.

[0201] In some embodiments of this application, the host base station can obtain cell information of neighboring cells from the network management system. Furthermore, the network management systems for the communication standard corresponding to the host base station and other communication standards can be independent of each other or shared. Specifically, when the network management systems for the communication standard corresponding to the host base station and other communication standards are independent, the cell information of the second neighboring cell can be manually configured in this network management system according to network planning, so that the host base station can obtain the cell information of the second neighboring cell from this network management system. When the communication standard corresponding to the host base station shares a network management system with the second communication standard, this network management system stores cell information for cells under different communication standards; therefore, the host base station can directly obtain the cell information of the second neighboring cell from this network management system.

[0202] In other implementations, the host base station can obtain the cell information of the second neighboring cell by interacting with the base station to which the second neighboring cell belongs. In these implementations, the type of message carrying the cell information of the second neighboring cell is not limited. For example, the cell information of the second neighboring cell can be carried through messages related to the establishment or configuration of the communication link between the base station to which the second neighboring cell belongs and the host base station, or through custom messages defined by both parties. The specific method can be determined according to the actual situation, and this application embodiment does not impose any limitations on this. Furthermore, different information within the cell information of the second neighboring cell can be carried in different messages and transmitted to the host base station.

[0203] This can enrich the ways in which the host base station obtains neighboring cell information, thereby improving the flexibility of obtaining neighboring cell information.

[0204] It should be noted that the various embodiments described in this application can be combined with each other or implemented individually without conflict, and this application does not limit this.

[0205] For ease of understanding, the following examples illustrate specific implementation methods:

[0206] In the following specific embodiments, the co-managed relay device is manifested as a 4G5G co-managed NCR (also known as NR / LTE NCR) that supports the forwarding of 4G and 5G radio frequency signals, and the 4G5G co-managed NCR is hosted on 5G. Furthermore, the second communication standard is represented as 4G; the cell information of the second neighboring cell is represented as LTE-level cell information; the radio frequency forwarding capability of the relay equipment in the second communication standard is represented as NCR LTE radio frequency forwarding capability; the second host cell is represented as an LTE host cell; the host base station of the 4G / 5G co-managed NCR is gNB; the first identifier is represented as gNB-side channel ID, and the second identifier is represented as eNB-side channel ID; the radio frequency forwarding control information of the second communication standard is represented as LTE FWD control information, which is configured through the LTE FWD control process; the radio frequency forwarding control information of 5G is represented as NCR FWD control information, which is configured through the NR FWD control process; the relay equipment management link is represented as an NCR management link, which is established through the NCR management link establishment process; the relay equipment management unit is represented as an NCR manageable and visible unit; the global cell identifier is represented as the LTE global cell identifier (Evolved Cell Global Identifier, ECGI); and the communication link is represented as an X2 link. However, it should be understood that the above representations are merely examples and do not limit the specific representation of the co-managed relay equipment.

[0207] For 4G and 5G co-managed NCR, such as Figure 5 As shown, it may include the following:

[0208] ①5G maintains LTE cell-level information;

[0209] ②NCR completes the 5G access and NR FWD control process;

[0210] ③ NCR LTE radio frequency forwarding capability acquisition process;

[0211] ④LTE host cell measurement process;

[0212] ⑤ The process of establishing an NCR management link with the LTE host cell;

[0213] ⑥LTE FWD control process;

[0214] ⑦ NCR (Navigate Controlled Visual Unit)

[0215] The specific explanation is as follows:

[0216] ①5G maintains LTE cell-level information.

[0217] For 4G and 5G co-managed NCR, the 5G side can obtain information about adjacent or covered LTE cells in advance. The 5G cell-level information maintenance process can include, but is not limited to, the following information: obtaining and maintaining "the ECGI of the LTE cell and its associated eNB information", "the X2 link information between the corresponding eNB and the local gNB", and "whether the corresponding LTE cell supports NCR co-managed deployment information".

[0218] There are four ways to obtain LTE cell-level information:

[0219] Method 1: Manual configuration, that is, the above information is directly configured in the 5G network management system according to the network plan.

[0220] Method 2: Through the standard evolved general terrestrial radio access network and the new radio dual connectivity (EN-DC) X2 interface established between 4G and 5G, the information of "LTE cell's ECGI and its home eNB information" and "X2 link information between the corresponding eNB and the local gNB" are maintained through standard information exchange via EN-DC X2 SETUP REQUEST, EN-DC CONFIGURATION UPDATE, and EN-DC X2 REMOVAL REQUEST. By adding custom fields to EN-DC X2 SETUP REQUEST and EN-DC CONFIGURATION UPDATE, the information of "whether the corresponding LTE cell supports NCR co-management deployment" is maintained through negotiation between 4G and 5G.

[0221] Method 3: Maintain the above information by using custom message interaction with vendor-defined X2 standard information elements.

[0222] Method 4: When using a single network management system for both 4G and 5G, obtain the above information directly through the network management system on the 5G side.

[0223] ②NCR completes the 5G access and NR FWD control process.

[0224] The NCR completes the 5G access and NR FWD configuration process, and reports the NR host cell information to the "NCR Visual and Manageable Unit".

[0225] ③ NCR LTE radio frequency forwarding capability acquisition process.

[0226] For 4G / 5G co-managed NCRs, the gNB can obtain the actual LTE coverage of the area covered by the NCR. This application can obtain this information by transmitting inter-system measurements, and this transmission needs to be based on the LTE radio frequency capabilities of the NCR. This application proposes a process for obtaining the NCR LTE radio frequency forwarding capability. Through this process, the gNB obtains the following information: "LTE radio frequency forwarding frequency bands supported by the NCR" and "LTE radio frequency forwarding bandwidth and center frequency point supported by the NCR," in order to obtain the LTE radio frequency forwarding frequency points supported by the NCR. In specific implementations, the above information can be obtained, but is not limited to, through the following methods:

[0227] Method 1: Manual configuration, that is, the above information is directly configured in the 5G network management system according to the network plan;

[0228] Method 2: Obtain the above information by querying the NCR. Specifically, this can be achieved by finding specific protocol fields or combinations of fields in the standard UE capabilities and using private agreements between the base station and the NCR to carry the above information; alternatively, it can be obtained through custom messages between the base station and the NCR.

[0229] ④ Measurement process of candidate LTE host cells.

[0230] Based on the NCR LTE radio frequency forwarding capability information obtained through the above process, and combined with the inter-system frequency information of the LTE neighboring cells of the gNB base station, the inter-system frequency points that can be covered by the LTE radio frequency forwarding capability of this NCR are used as the LTE inter-system measurement frequency points of this NCR, and are sent to the NCR in the form of periodic measurement configuration or event-based measurement configuration.

[0231] The NCR reports measurements from different systems based on this measurement configuration information.

[0232] Based on the PCI information (which may be multiple) in the inter-system measurement report reported by the NCR, the gNB determines the candidate LTE ECGI host cell (which may be multiple) for the NCR. The ECGI acquisition process can be implemented in the following ways:

[0233] Method 1: Based on the PCI information in the inter-system measurement report, the gNB searches for the ECGI information corresponding to the PCI in the neighbor cell relationship configuration (i.e., the aforementioned cell relationship configuration);

[0234] Method 2: Issue the ECGI measurement configuration for this PCI to the NCR, and determine the host ECGI based on the ECGI measurement report submitted by the NCR.

[0235] Method 3: Measure the ECGI of the PCI through a regular commercial terminal under this NCR: Select a regular commercial terminal under this NCR to issue the ECGI measurement configuration for the PCI, and determine the host ECGI based on the ECGI measurement report reported by the regular commercial terminal.

[0236] ⑤ The process of establishing a management link with the LTE host cell NCR.

[0237] The purpose of this process is to maintain a management channel logical link for this NCR between 4G and 5G. The specific process is as follows:

[0238] Based on the candidate LTE host ECGI information and the "5G to LTE cell-level information maintenance process" information, the gNB matches and finds the "LTE cell ECGI and its associated eNB information", "X2 link information between the corresponding eNB and the gNB", and "whether the corresponding LTE cell supports NCR co-management deployment information" associated with the candidate LTE host cell. If the candidate cell has an X2 link and the corresponding LTE cell supports NCR co-management deployment, the gNB initiates a 4G-5G inter-NCR management channel establishment request to the eNB. This request needs to include: NCR identity information, ECGI information of the NCR candidate LTE cell, and gNB-side channel ID. After receiving the NCR management channel establishment request, the eNB maintains the NCR information and gNB-side channel ID in the corresponding LTE cell, assigns the eNB-side channel ID, and replies to the gNB. If this process is successful, the 4G-5G management channel logical link for this NCR ID is successfully established, and the LTE host cell information is reported to the "NCR visible and manageable unit".

[0239] ⑥LTE FWD control, monitoring, and management process.

[0240] The eNB interacts with and manages LTE FWD control information with the NCR based on the above management channel logical link. This includes exchanging LTE FWD time slot turn-off or turn-on control information, LTE cell NI information, user number information under NCR, NCR radio frequency turn-off, and NCR alarm reporting.

[0241] The NCR and LTE FWD control information gNB radio interface interaction channel for 4G and 5G co-managed systems can take the following two forms:

[0242] Method 1: For example Figure 6a As shown, for 4G and 5G co-managed NCR, each of the two FWDs (i.e., LTE NCR FWD and NR NCRFWD) uses an independent DRB channel. In this approach, the LTE NCR FWD and NR NCR FWD information are isolated, and various data transmission and detection channels are isolated at the channel level, without affecting each other, and have good scalability.

[0243] Method 2: For example Figure 6bAs shown, for 4G and 5G co-managed NCR, two FWDs (i.e., LTE NCR FWD and NR NCRFWD) share a single DRB channel. In this mode, the information of LTE NCR FWD and NR NCR FWD is fused. When different operations are required for different NCRFWDs, different data formats or identifiers are needed for display differentiation. When simultaneous control is required, both FWDs can be controlled simultaneously with a single message, thus achieving information fusion.

[0244] Third, the NCR co-management framework concept proposed in this application can not only be applied between 4G and 5G, but also be used to create an NCR co-management framework between other standards, all of which fall within the scope of protection of this application.

[0245] For ease of understanding, the following description uses Examples 1 to 3.

[0246] Example 1: Initial LTE Host Takeover Process (Scenario where the LTE host cell ECGI+4G5G shares a single OAM DRB channel is obtained through inter-system neighbor cells configured by the base station), for details please refer to Figure 7 .

[0247] 1. 5G's maintenance process for LTE cell-level information.

[0248] This embodiment establishes a standard EN-DC X2 interface between 4G and 5G networks. It maintains the "ECGI of the LTE cell and its associated eNB information" and the "X2 link information between the corresponding eNB and the local gNB" through standard information exchange via EN-DC X2 SETUP REQUEST, EN-DC CONFIGURATION UPDATE, and EN-DC X2 REMOVAL REQUEST. It also negotiates and maintains the "whether the corresponding LTE cell supports NCR co-management deployment information" between 4G and 5G networks by adding custom fields to EN-DC X2 SETUP REQUEST and EN-DC CONFIGURATION UPDATE.

[0249] 2. NCR completed access and takeover in 5G.

[0250] The NCR completes 5G access, establishes a DRB radio channel for the operation and maintenance (OAM) of the NR NCR FWD, and performs related FWD configuration processes, and reports NR host cell information to the "NCR Visual and Manageable Unit".

[0251] 3. NCR LTE radio frequency forwarding capability acquisition process.

[0252] This embodiment uses NCR private message interaction to obtain NCR LTE radio frequency forwarding capabilities, including "LTE radio frequency forwarding frequency bands supported by NCR" and "LTE radio frequency forwarding bandwidth and center frequency point supported by NCR" information.

[0253] 4. LTE host cell measurement process.

[0254] Based on the NCR LTE radio frequency forwarding capability information obtained through the above process, and combined with the inter-system frequency information of the gNB base station's LTE neighboring cells, the base station uses the inter-system frequency points that can be covered by the NCR LTE radio frequency forwarding capability as the LTE inter-system measurement frequency points of the NCR, and issues periodic LTE inter-system B1.

[0255] The NCR periodically sends LTE inter-system measurement report information to the base station.

[0256] In this embodiment, the neighbor cell relationship method configured by gNB is used for lookup. The base station searches for the ECGI information corresponding to the PCI in the neighbor cell relationship configuration configured by gNB based on the PCI information (which may be multiple) in the inter-system measurement report. The ECGI cell is then used as the LTE host candidate cell.

[0257] 5. The process of establishing a management link with the LTE host cell NCR.

[0258] The purpose of this process is to maintain a management channel logical link for this NCR between 4G and 5G. The specific process is as follows:

[0259] Based on the ECGI information of the LTE candidate host cell and the "5G to LTE cell-level information maintenance process" information, the base station matches and finds the "LTE cell's ECGI and its associated eNB information", "the X2 link information between the corresponding eNB and the gNB", and "whether the corresponding LTE cell supports NCR co-management deployment information" associated with the LTE candidate host cell. If the candidate cell has an X2 link and the corresponding LTE cell supports NCR co-management deployment, a 4G-5G inter-NCR management channel establishment request is initiated to the eNB. This request needs to include: NCR identity information, ECGI information of the NCR candidate LTE cell, and gNB-side channel ID. After receiving the NCR management channel establishment request, the eNB maintains the NCR information and gNB-side channel ID in the corresponding LTE cell, assigns the eNB-side channel ID, and replies to the gNB. If this process is successful, the 4G-5G management channel logical link for this NCR ID is successfully established, and the LTE host cell information is reported to the "NCR visible and manageable unit".

[0260] If the interaction is successful, the 4G / 5G management channel logical link for this NCR ID is successfully established, and the LTE host cell information is reported to the "NCR visual and manageable unit".

[0261] 6. LTE FWD control, monitoring, and management process.

[0262] The eNB interacts with and manages LTE FWD control information with the LTE NCR based on the above management channel logical link. This includes interacting with LTE FWD slot turn-off or turn-on control information, LTE cell NI information, user number information under NCR, NCR radio frequency turn-off, and NCR alarm reporting.

[0263] In this embodiment, on the gNB-side air interface, the two FWDs (i.e., LTE NCR FWD and NR NCR FWD) are transmitted using the same OAM DRB channel. In this mode, the LTE NCR FWD and NR NCR FWD information are fused. When different operations are required for different NCR FWDs, they need to be distinguished by different data formats or identifiers. When simultaneous control is required, both FWDs can be controlled simultaneously with a single message, achieving information fusion.

[0264] Example 2: Initial LTE Host Takeover Process (Scenario of obtaining ECGI+4G and 5G independent OAM DRB channels of LTE host cell through NCR ECGI measurement), see details below. Figure 8 .

[0265] 1. 5G's maintenance process for LTE cell-level information.

[0266] This embodiment establishes a standard EN-DC X2 interface between 4G and 5G networks. It maintains the "ECGI of the LTE cell and its associated eNB information" and the "X2 link information between the corresponding eNB and the local gNB" through standard information exchange via EN-DC X2 SETUP REQUEST, EN-DC CONFIGURATION UPDATE, and EN-DC X2 REMOVAL REQUEST. It also negotiates and maintains the "whether the corresponding LTE cell supports NCR co-management deployment information" between 4G and 5G networks by adding custom fields to EN-DC X2 SETUP REQUEST and EN-DC CONFIGURATION UPDATE.

[0267] 2. NCR completed access and takeover in 5G.

[0268] The NCR completes 5G access and establishes a DRB radio channel for the operation and maintenance (OAM) of the NR NCR FWD, as well as the relevant FWD configuration process (standard protocol content); and reports the NR host cell information to the "NCR Visual and Manageable Unit".

[0269] 3. NCR LTE radio frequency forwarding capability acquisition process.

[0270] This embodiment uses NCR private message interaction to obtain NCR LTE radio frequency forwarding capabilities, including "LTE radio frequency forwarding frequency bands supported by NCR" and "LTE radio frequency forwarding bandwidth and center frequency point supported by NCR" information.

[0271] 4. LTE host cell measurement process.

[0272] Based on the NCR LTE radio frequency forwarding capability information obtained through the above process, and combined with the inter-system frequency information of the gNB base station's LTE neighboring cells, the base station uses the inter-system frequency points that can be covered by the NCR LTE radio frequency forwarding capability as the LTE inter-system measurement frequency points of the NCR, and issues periodic LTE inter-system B1.

[0273] The NCR periodically sends LTE inter-system measurement report information to the base station.

[0274] In this embodiment, the ECGI measurement configuration of the PCI is issued to the NCR. The ECGI of the LTE host of the NCR is obtained according to the ECGI measurement report reported by the NCR. After obtaining it, the ECGI cell is used as the LTE host candidate cell.

[0275] 5. Establish an independent OAM DRB channel for LTE NCR FWD.

[0276] The gNB initiates a second DRB establishment with the NCR, that is, to establish another DRB bearer according to the standard protocol. (This bearer is used to transmit "6. LTE FWD control, monitoring, and management process" information).

[0277] 6. The process of establishing a management link with the LTE host cell NCR.

[0278] The purpose of this process is to maintain a management channel logical link for this NCR between 4G and 5G. The specific process is as follows:

[0279] Based on the ECGI information of the LTE candidate host cell and the "5G to LTE cell-level information maintenance process" information, the base station matches and finds the "LTE cell's ECGI and its associated eNB information", "the X2 link information between the corresponding eNB and the gNB", and "whether the corresponding LTE cell supports NCR co-management deployment information" associated with the LTE candidate host cell. If the candidate cell has an X2 link and the corresponding LTE cell supports NCR co-management deployment, a 4G-5G inter-NCR management channel establishment request is initiated to the eNB. This request needs to include: NCR identity information, ECGI information of the NCR candidate LTE cell, and gNB-side channel ID. After receiving the NCR management channel establishment request, the eNB maintains the NCR information and gNB-side channel ID in the corresponding LTE cell, assigns the eNB-side channel ID, and replies to the gNB. If this process is successful, the 4G-5G management channel logical link for this NCR ID is successfully established, and the LTE host cell information is reported to the "NCR visible and manageable unit".

[0280] If the interaction is successful, the 4G / 5G management channel logical link for this NCR ID is successfully established, and the LTE host cell information is reported to the "NCR visual and manageable unit".

[0281] 7. LTE FWD control, monitoring, and management process.

[0282] The eNB interacts with and manages LTE FWD control information with the LTE NCR based on the above management channel logical link. This includes interacting with LTE FWD slot turn-off or turn-on control information, LTE cell NI information, user number information under NCR, NCR radio frequency turn-off, and NCR alarm reporting.

[0283] In this embodiment, on the gNB-side air interface radio side, the two FWDs (i.e., LTE NCR FWD and NR NCR FWD) independently establish their own OAM DRB channels. In this mode, the LTE NCR FWD and NR NCR FWD information are isolated, and various data transmission and detection channels are isolated at the channel level, without affecting each other, providing good scalability.

[0284] Example 3: Host cell change scenario, see details below. Figure 9 .

[0285] 1. When LTE NCR accesses an NR cell, gNB completes abnormal measurement according to the aforementioned embodiment;

[0286] 2. The LTE NCR measures the PCI, and the gNB completes the NCR management link establishment in the eNB1 according to the aforementioned embodiment;

[0287] 3. Due to changes in LTE cell signal coverage or NCR heterogeneous radio frequency capabilities, NCR measures other new PCIs. After the gNB obtains the ECGI according to the aforementioned embodiments, and the new ECGI is on the eNB2, it supports NCR co-deployment.

[0288] 4. The gNB initiates an NCR heterogeneous management logic link release command to the eNB1, which needs to carry "NCR identity information", "local channel ID", and "peer channel ID"; after receiving the information, the eNB1 releases and clears its own NCR-related information and replies that the release is complete.

[0289] 5. gNB simultaneously initiates the 4G / 5G inter-NCR management channel establishment process to eNB2. The specific process is the same as in the aforementioned Implementation Example 1, and will not be repeated here.

[0290] exist Figures 7 to 9 In this context, the relay device management link establishment request is represented as an NCR heterogeneous management logical link establishment request; the relay device management link establishment response is represented as an NCR heterogeneous management logical link establishment response; the NCR FWD control information is represented as NCR heterogeneous FWD control information; the relay device management link release command is represented as an NCR heterogeneous management logical link release command; and the relay device management link release completion indication is represented as an NCR heterogeneous management logical link release completion.
