Description

Technical Field

[0001] This application relates to the field of wireless communication technology, and more specifically, to a terminal device, a base station device, and a mobile access system in a mobile access device. Background Technology

[0002] The 3rd Generation Partnership Project (3GPP) has added several extended access devices to its 5G system, namely Integrated Access and Backhaul (IAB) introduced in Release 16 and Network-Controlled Repeaters (NCR) introduced in Release 18. IAB features include: Introduced in 3GPP 5G Release 16, IAB enables base stations to provide radio access and backhaul connectivity for devices, eliminating the need for more expensive wired backhaul. IAB refers to using a portion of the access spectrum as backhaul. 5G promises high bandwidth capabilities from the millimeter-wave band. However, high-frequency deployments have limited coverage and require denser base station layouts, significantly increasing deployment costs. A major factor contributing to this cost increase is the need for underground fiber optic deployment. Using a portion of the radio spectrum in IAB for base station backhaul instead of fiber optics now presents an attractive solution for cost-effective dense deployment. A major advantage of IAB is its ability to flexibly and densely deploy new radio (NR) cells without proportionally increasing the density of the transmission network. The protocol architecture of the IAB-node uses a Layer 2 architecture, separating the Centralized Unit (CU) from the Distributed Unit (DU), such as... Figure 1 As shown, the clock synchronization uses OTA (over-the-air) clock synchronization.

[0003] The technical characteristics of NCR are as follows:

[0004] (1) The NCR structure consists of two main functional blocks in the repeater-NCR controlled by the 5G wireless network base station (thenextgeneration NodeB, gNB), such as Figure 2As shown, these are: NCR-Mobile Terminal (MT) and NCR-Fwd (NCR-Forwarding). The NCR-MT module uses the 5G (NR) network Uu interface to establish communication with the gNB via the C-link control link; it can exchange side control information (such as beamforming, UL / DL handover and on / off switching, and NCR-Fwd module management). The NCR-MT module provides control and status signaling exchange with the gNB via C-link, fulfilling its responsibilities by supporting a subset of UE functions.

[0005] (2) C-link characteristics: In NCR, the characteristics of C-link and IAB in transmission and reception are as follows: C-link's DL and IAB link DL can be executed simultaneously or in time division multiplexing (TDM) mode; C-link's UL and IAB link UL can be performed in TDM mode; gNB controls multiplexing simultaneously when considering NCR capability, and the simultaneous transmission of UL in C-link and IAB depends on NCR capability;

[0006] (3) NCR-Fwd Features: This module amplifies and forwards the UL / DL radio frequency signal (RF) between the gNB and UE via the IAB and access link. The NCR-Fwd module is implemented using two sets of planar antennas: one set for the IAB link and the other set for the access link and an RF amplifier. The NCR-Fwd module focuses primarily on signal amplification and (analog) beamforming, eliminating the need for advanced digital receivers or transmitter chains. The performance requirements of the beamforming antenna are not as high as those of macro base station or IAB node antennas, and cost-effectiveness and ease of manufacturing are key priorities.

[0007] (4) Both NCR-MT and NCR-Fwd can operate in the same or different frequency bands. NCR-MT must operate within the frequency band forwarded by NCR-Fwd, using that frequency band as a baseline. When NCR-MT and NCR-Fwd operate in the same frequency band, C-link and IAB will encounter similar large-scale channel characteristics, thus simplifying the control of IAB between gNB and NCR-Fwd.

[0008] The above solution has some problems. For example, IAB needs to support a CU / DU separation architecture, and the macro base stations it serves need to support some core network functions. Therefore, the cost of upgrading the existing network and implementing IAB are both high. In addition, NCR only supports fixed deployment, and from the UE's perspective, NCR is a transparent repeater and does not support L2 / L3 processing capabilities. Therefore, in order to support mobile scenarios without upgrading the existing 5G base stations, a new coverage extension solution is needed, namely... Figure 3 The mobile wireless access device (MWAB) shown is an example. Therefore, existing solutions have the following problems:

[0009] (1) There is no clear indication of how to not support multi-hop capability: IAB and others support multi-hop capability, but WAB does not clearly indicate how to not support multi-hop capability, especially when a cell has been broadcast by WAB, how to prevent other WAB-MT from accessing.

[0010] (2) It is not clear whether WAB can be connected to IAB and NCR devices: The current protocol does not clearly state whether IAB and NCR can be connected to WAB. Without such restrictions, there will be problems with protocol interoperability.

[0011] (3) Unable to solve the identification problem during handover: The protocol does not clearly specify if the target cell for handover has some kind of anti-multi-hop indication information set. If the behavior of the terminal during handover cannot be determined, it may lead to interoperability problems between the base station and the terminal.

[0012] Based on the above analysis of needs and reasons, the current 3GPPRel-18 protocol cannot meet the deployment requirements for low-cost mobile access devices. It is necessary to enhance its functionality through new standardization methods to meet the needs of network deployment and optimization. Summary of the Invention

[0105] Figure 4 This is a schematic diagram of a terminal device in a mobile access device according to an embodiment of this application, such as... Figure 4 As shown, the terminal devices in the mobile access device include a first terminal device.

[0106] The first terminal device is included in the mobile access device; the first terminal device supports at least one of the following states: Radio Resource Control (RRC) connected state, RRC idle state, and RRC inactive state.

[0107] It is worth noting that the mobile access equipment includes a first terminal device and at least one base station device, including a first base station device. In other words, the mobile access equipment is composed of a terminal portion and base station devices, wherein the base station devices at least include the first base station device and may also include other base station devices, and the terminal portion includes the first terminal device. Alternatively, the mobile access equipment consists of a first terminal device and one or more base station devices, wherein the base station devices at least include the first base station device.

[0108] The first terminal device, as a terminal component of the mobile access device, has the ability to support multiple states of RRC, including but not limited to RRC connected state, RRC idle state, and RRC inactive state. In other words, the first terminal device, i.e., the terminal-side entity in the mobile access device, has the ability to adapt to multiple operating modes under the RRC protocol, including but not limited to maintaining the RRC connected state, entering the RRC idle state, and being in the RRC inactive state.

[0109] The first terminal device receives first access control information and / or second access control information and / or access cell restriction list sent by the network via broadcast message or RRC message. The first access control information includes access control information of at least one cell and / or mobile access device terminal equipment control information of at least one cell. The mobile access device terminal equipment control information is used to prohibit or allow terminal equipment in the mobile access device to access the network. The access cell restriction list is allowed and / or prohibited cell information or frequency point information. The cell information includes at least one of cell identifier and cell physical identifier.

[0110] For example, the first terminal device receives first access control information sent by the network via a broadcast message; the first terminal device receives second access control information sent by the network via an RRC message; the first terminal device receives an access cell restriction list sent by the network via a broadcast message; the first terminal device receives the first access control information and the second access control information sent by the network via an RRC message; and the first terminal device receives the first access control information, the second access control information, and the access cell restriction list sent by the network via an RRC message.

[0111] For example, the access cell restriction list contains allowed cell information; the access cell restriction list contains prohibited cell information; the access cell restriction list contains both allowed and prohibited cell information; the access cell restriction list contains frequency point information.

[0112] The first terminal device determines whether the network prohibits or allows the first terminal device to access the target cell, or determines the target cell that supports the first terminal device's RRC-triggered connection reconstruction.

[0113] For example, the first terminal device determines, based on the received first access control information, that the network allows the first terminal device to access the target cell; the first terminal device determines, based on the received first access control information, that the network prohibits the first terminal device from accessing the target cell; the first terminal device determines, based on the received second access control information, that the network allows the first terminal device to access the target cell; the first terminal device determines, based on the received second access control information, that the network prohibits the first terminal device from accessing the target cell; the first terminal device determines, based on the received access cell restriction list, that the network prohibits the first terminal device from accessing the target cell; the first terminal device determines, based on the received first access control information and the access cell restriction list, that the network prohibits the first terminal device from accessing the target cell; and the first terminal device determines, based on the received first access control information, second access control information, and access cell restriction list, the target cell that supports the first terminal device's RRC-triggered connection reconstruction.

[0114] Preferably, the first access control information is configured at the granularity of each public land mobile network (PLMN), each independent non-public network (SNPN), all PLMNs, or all SNPNs.

[0115] The network can set first access control information for each PLMN, which can be specific to a cell within a PLMN and control the access behavior of terminal devices belonging to that PLMN. Similarly, the network can also set first access control information for each SNPN, which can be specific to a cell within a SNPN and control the access behavior of terminal devices belonging to that SNPN.

[0116] The network can also configure first access control information applicable to all PLMNs. This configuration affects all terminal devices within the PLMN, providing a unified access control standard. Similarly, the network can also configure first access control information applicable to all SNPNs. This configuration affects all terminal devices within the SNPN, providing a unified access control standard.

[0117] Preferably, or optionally, the first terminal device supports some or all of the user equipment (UE) functions, wherein the UE functions include at least one of 4G, 5G, and 6G functions.

[0118] For example, the first terminal device supports partial 4G functionality; the first terminal device supports all 4G functionality; the first terminal device supports partial 5G functionality; the first terminal device supports all 5G functionality; the first terminal device supports partial 6G functionality; the first terminal device supports all 6G functionality; the first terminal device supports partial 4G and 5G functionality; the first terminal device supports all 4G and 5G functionality; the first terminal device supports partial 4G, 5G, and 6G functionality; the first terminal device supports all 4G, 5G, and 6G functionality.

[0119] According to some optional embodiments of this application, the first terminal device establishes an Internet Protocol (IP) connection for the backhaul link of the first base station device, wherein the first base station device is a base station device in a mobile access device, and the base station portion of the mobile access device includes at least one base station device, including the first base station device. The mobile access device is deployed on a moving or stationary object to provide services to terminal devices located inside or outside the object.

[0120] The deployment flexibility of mobile access devices enables them to provide services to terminal devices in various scenarios, whether moving or stationary. These devices adapt to different environments and needs, providing users with a seamless connectivity experience. Mobile access devices can be installed in vehicles, such as trains, buses, or autonomous vehicles, providing high-speed internet access to passengers' smart devices. Deployed on drones, mobile access devices can provide stable data links to ground control stations or long-range drone fleets, supporting high-definition video transmission, remote monitoring, and real-time control. They are an important component of drone applications such as cargo transportation, agricultural monitoring, and disaster relief. In maritime and air navigation, mobile access devices provide connectivity services to passengers and staff on ships and aircraft, meeting their communication, entertainment, and work needs, while also supporting remote monitoring and data transmission for ships and aircraft.

[0121] Inside buildings, mobile access devices can be integrated into small base stations or indoor distribution systems to enhance 5G signal coverage and provide faster and more stable network connections for indoor terminal devices. This is suitable for large venues, office buildings, and residential areas. In high-traffic areas such as airports, train stations, and shopping malls, deploying mobile access devices can effectively increase network capacity, alleviate network congestion, and improve user experience.

[0122] Preferably, a first interface exists between the first terminal device and the first base station device; the first terminal device configures or obtains the status information, parameter information, or configuration information of the first base station device through the first interface.

[0123] Through the first interface, the first terminal device can obtain real-time status information of the first base station device. This includes, but is not limited to, the base station's carrier status, signal quality (such as RSRP, RSRQ), cell load, number of connected terminals, and backhaul link quality. The first terminal device can send parameter configuration information to the first base station device through the first interface to influence the base station's operation or status, including adjusting transmission power, setting beamforming parameters, updating QoS requirements, and controlling multiple access parameters, ensuring that communication between the terminal device and the base station device meets specific QoS standards and network policies. The first terminal device can also receive configuration information from the first base station device, including network-allocated resources, cell parameters, encryption keys, authentication information, QoS configuration, and cell block lists. The first terminal device will adjust its communication behavior based on this information.

[0124] Preferably, when the first terminal device is in an RRC inactive state, the first base station device continues to receive and / or transmit wireless signals.

[0125] In other words, when the first terminal device is in an RRC inactive state, the first terminal device receives wireless signals sent by the first base station device, and / or sends wireless signals to the first base station device.

[0126] Preferably, when the first terminal device transitions from the RRC connected state to the RRC idle state, the first base station device stops receiving and / or transmitting wireless signals.

[0127] In other words, when the first terminal device transitions from an RRC connected state to an RRC idle state, the first terminal device stops receiving wireless signals from the first base station device, and / or stops sending wireless signals to the first base station device. Alternatively, when the first terminal device transitions from an RRC connected state to an RRC idle state, the first base station device stops sending wireless signals to the first terminal device, and / or stops receiving wireless signals from the first terminal device, and / or deletes the interface information between the first base station and the core network.

[0128] Preferably, when the first terminal device transitions from the RRC connected state to the RRC inactive state, the first base station device continues to receive and / or transmit wireless signals.

[0129] In other words, when the first terminal device transitions from an RRC connected state to an RRC inactive state, the first terminal device receives a wireless signal sent by the first base station device, and / or sends a wireless signal to the first base station device. Alternatively, when the first terminal device transitions from an RRC connected state to an RRC inactive state, the first base station device sends a wireless signal to the first terminal device, and / or receives a wireless signal sent by the first terminal device, and / or deletes the interface information between the first base station and the core network.

[0130] Preferably, if the first terminal device detects that the wireless link establishment has failed, the first terminal device triggers the RRC connection reconstruction process, wherein the first base station device stops receiving and / or transmitting wireless signals before the RRC connection reconstruction process is completed.

[0131] In other words, if the first terminal device detects that the wireless link establishment has failed, the first terminal device triggers the RRC connection reconstruction process. Before the RRC connection reconstruction process is completed, the first base station device stops sending wireless signals to the first terminal device and / or stops receiving wireless signals sent by the first terminal device.

[0132] Preferably, when the first terminal device is switched to a 4G base station, the first base station device stops receiving and / or transmitting wireless signals.

[0133] Preferably, the network is the serving cell where the first terminal device is located, or the stationary cell in the RRC idle state, or the neighboring cell of the serving cell, or the neighboring cell of the stationary cell.

[0134] When the first terminal device is in RRC connected state, the serving cell it connects to is the cell for which the network provides data transmission, control information exchange, and radio resource scheduling. The serving cell is the direct environment in which the terminal device performs normal communication activities, including uplink data transmission, downlink data reception, handover control, and quality monitoring. In RRC idle state, the first terminal device camps in a cell. Although it does not transmit data with the network, it still listens for system information broadcasts to receive paging messages or perform cell reselection. When the first terminal device moves within the serving cell, approaching or crossing cell boundaries, neighboring cells become potential handover targets or candidate cells. The network monitors the signal strength and quality between the terminal device and neighboring cells to determine whether and when to perform cell handover, ensuring communication continuity and service quality for the terminal device. In RRC idle state, the first terminal device may consider moving from its current camped cell to a neighboring cell, for example, for cell reselection.

[0135] Preferably, the target cell includes: a cell that sends broadcast messages or RRC messages, at least one of the following: the cell where the first terminal device is camped in the RRC idle state, the handover cell, and the neighboring cell; the air interface technology of the target cell is 5G or a subsequent evolution technology.

[0136] In other words, the target cell uses a 5G-based wireless air interface technology standard, specifically, it follows the 5G NR technical specifications developed by 3GPP or future evolution versions.

[0137] According to some alternative embodiments of this application, the first access control information and / or the second access control information and / or the access cell restriction list are sent by a broadcast message from the first base station device, or by a broadcast message from a cell in the second base station, wherein the first base station device is a base station device in a mobile access device, and the base station portion of the mobile access device includes at least one base station device, including the first base station device; the second base station is a base station device in the mobile access device, or the second base station is not a base station device in the mobile access device.

[0138] It is understandable that the second base station, which may be located inside or outside the mobile access equipment, may also send the first access control information and / or the second access control information and / or the access cell restriction list to the first terminal equipment through its broadcast channel.

[0139] Preferably, the access control information includes at least one of the following: Network Control Repeater (NCR) support indication information, Integrated Access and Backhaul (IAB) support indication information; the second access control information includes at least one of the following: Cell Prohibition Indication Information, Cell Reservation Information for Current Operation, Cell Reservation Information for Future Use, Cell Reservation Information for Preset Purposes, and Unified Access Control Configuration Information. The Unified Access Control Configuration Information includes: Access Classification Information and Access Identification Information related to the Cell Prohibition Indication Information.

[0140] For example, the access control information may include: Network Control Repeater (NCR) support indication information. Alternatively, the access control information may include: Network Control Repeater (NCR) support indication information and IAB support indication information. The second access control information may include cell prohibition indication information. Alternatively, the second access control information may include cell prohibition indication information and cell reservation information for current operation. Alternatively, the second access control information may include cell prohibition indication information, cell reservation information for current operation, cell reservation information for future use, and unified access control configuration information. Or, the second access control information may include cell prohibition indication information, cell reservation information for current operation, cell reservation information for future use, cell reservation information for a preset purpose, and unified access control configuration information.

[0141] Preferably, the first terminal device determines whether the network prohibits or allows the first terminal device to access the target cell by the following method: if the first access control information and / or the second access control information and / or the access cell restriction list are sent by a broadcast message from the first base station device or by a broadcast message from a cell in the second base station, and the first access control information includes access control information of at least one cell and / or mobile access device terminal device control information of at least one cell, then the network is determined to prohibit the first terminal device from accessing the target cell.

[0142] For example, if the first access control information is sent by a broadcast message from the first base station device, and the first access control information includes access control information for one cell, then the network determines that the first terminal device is prohibited from accessing the target cell. If the first access control information and the second access control information are sent by a broadcast message from the first base station device, and the first access control information includes access control information for two cells, then the network determines that the first terminal device is prohibited from accessing the target cell. If the first access control information, the second access control information, and the access cell restriction list are sent by a broadcast message from a cell in the second base station, and the first access control information includes access control information for three cells, then the network determines that the first terminal device is prohibited from accessing the target cell.

[0143] Preferably, if the second access control information includes unified access control configuration information, the first terminal device ignores at least one of the following: cell prohibition indication information, cell reservation information for current operation, cell reservation information for future use, and cell reservation information for preset purpose.

[0144] For example, if the second access control information includes unified access control configuration information, the first terminal device ignores the cell prohibition indication information and the cell reservation information used for the current operation. Alternatively, if the second access control information includes unified access control configuration information, the first terminal device ignores the cell prohibition indication information, the cell reservation information used for the current operation, the cell reservation information used for future use, and the cell reservation information used for a preset purpose.

[0145] Preferably, the access cell restriction list is obtained through the Operation, Management, and Maintenance (OAM) configuration of the network management system. The first terminal device is configured to allow access to the cell list and / or prohibit access to the cell list; when the OAM configuration of the network management system is a candidate list for cell reselection, the first terminal device is configured to allow access to the cell list; when the OAM configuration of the network management system is not a candidate list for cell reselection, the first terminal device is configured to refuse to use cells in the prohibition list as cells for reselection.

[0146] Preferably, the first terminal device determines whether the network prohibits or allows the first terminal device to access the target cell, which can be achieved by the following method: If the first terminal device is a network control repeater mobile terminal device (NCR-MT) or an integrated access and backhaul mobile terminal device (IAB-MT), and the first access control information and / or the second access control information and / or the access cell restriction list are sent by a broadcast message from the first base station device or by a broadcast message from a cell in the second base station, and the first access control information includes mobile access device terminal device control information, the first terminal device determines that the network prohibits the first terminal device from accessing the target cell.

[0147] For example, if the first terminal device is a Network Control Repeater Mobile Terminal Device (NCR-MT), and the first access control information is sent by a broadcast message from a first base station device, and the first access control information includes mobile access device terminal device control information, the first terminal device determines that the network prohibits the first terminal device from accessing the target cell. Alternatively, if the first terminal device is an Integrated Access and Backhaul Mobile Terminal Device (IAB-MT), and the first and second access control information are sent by a broadcast message from a cell in a second base station, and the first access control information includes mobile access device terminal device control information, the first terminal device determines that the network prohibits the first terminal device from accessing the target cell.

[0148] In some optional embodiments of this application, the first access control information and / or the second access control information and / or the access cell restriction list are sent by the RRC message of the first base station device, or by the RRC message of the second base station, wherein the first base station device is a base station device in the mobile access device, and the base station portion of the mobile access device includes at least one base station device including the first base station device; the second base station is a base station device in the mobile access device, or the second base station is not a base station device in the mobile access device; the RRC message is a handover command message or an RRC reconfiguration message.

[0149] It is understandable that the second base station, which may be located inside or outside the mobile access equipment, may also send the first access control information and / or the second access control information and / or the access cell restriction list to the first terminal equipment through its broadcast channel.

[0150] Preferably, when the RRC message includes mobile access device terminal control information, the first terminal device selects another cell for access or attempts to access during the RRC connection reconstruction process.

[0151] Preferably, if the RRC message does not include mobile access device terminal equipment control information, the mobile access device terminal equipment control information is searched in the broadcast message of the first base station device or in the broadcast message of the cell in the second base station; if the mobile access device terminal equipment control information is searched in the broadcast message of the first base station device or in the broadcast message of the cell in the second base station, the RRC connection reconstruction process of the first terminal device is triggered.

[0152] Preferably, during the RRC connection reconstruction process, the first terminal device instructs the first base station device to stop providing services to the first terminal device.

[0153] Preferably, after accessing the first network, the first terminal device establishes a first connection with the first network, wherein the first connection includes at least one of: a Protocol Data Unit (PDU) session between the second base station and the first network, a Data Radio Bearer (DRB) between the first terminal device and the second base station, and a Transmission Control Protocol (TCP / IP) connection between the first terminal device and the first network; the first base station device establishes a second connection with the second network on the first connection; the first network and the second network are the same core network or different core networks; the second connection is a connection between the control plane and the user plane of the first base station device and the second network.

[0154] The establishment of a PDU session signifies that the network has allocated a specific IP address and user plane path to the first terminal device, enabling it to conduct data communication over the network. Once the first terminal device accesses the network and establishes a PDU session, a DRB will be established between the first terminal device and the second base station to support uplink and downlink data transmission. The establishment and management of the DRB are handled by the network's RRC layer, dynamically adjusted based on network resource availability and the terminal device's quality of service requirements.

[0155] The first base station equipment (part of the mobile access equipment) not only establishes a connection with the first network (core network), but may also establish a second connection with a second network (which may be another part of the same core network or a completely different core network) based on the first connection. This second connection refers to the connection between the control plane and the user plane, where the control plane connection is used to transmit control information, such as handover commands and configuration updates, while the user plane connection is used for data transmission. The establishment of the second connection can be to resolve data forwarding between multiple core network domains, or to support flexible operation of the mobile access equipment between different core network domains.

[0156] As some optional embodiments of this application, an architecture for a mobile access device and its connected core network equipment and backhaul equipment are provided. Specifically, the mobile access device (MWAB) includes a WAB-gNB and a WAB-MT, wherein the WAB-MT is connected to the core network CN1 and its PLMN is 1; the WAB-gNB is connected to the core network CN2 and its PLMN is 2, and BH gNB2 is a base station used to connect to the mobile access device. This embodiment describes an initial connection process of the mobile access device as follows:

[0157] 1. The second access control information set in the broadcast message MIB of BH gNB2: the cell prohibition indication information is set as follows:

[0158] cellBarred ENUMERATED{notBarred}.

[0159] In this example, the MIB contains second access control information, specifically, the cellBarred field is set to notBarred, indicating that there are no restrictions on terminal access to the BH gNB2 cell. This information is crucial for WAB-MT to assess whether access to BH gNB2 is possible.

[0160] 2. WAB-MT believes that BH gNB2 can be connected.

[0161] 3. Furthermore, BH gNB2 is not in the prohibited cell list configured by OAM. WAB-MT initiates a random access procedure on BH gNB2 to complete the connection establishment with the core network.

[0162] After receiving the MIB information from BH gNB2, the WAB-MT evaluates the value of the cellBarred field and confirms it as notBarred, meaning the terminal considers BH gNB2 accessible. The WAB-MT also checks the prohibited cell list in the OAM configuration to ensure BH gNB2 is not listed. If BH gNB2 is neither prohibited in the MIB information nor in the OAM configuration, the WAB-MT will prepare to initiate a random access procedure to establish a connection with BH gNB2. The WAB-MT terminal attempts to access BH gNB2 by initiating the random access procedure. Random access is the first step in establishing a connection between the mobile terminal and the base station. It allows the terminal to synchronize with the base station and request resources to send access requests. After successfully completing the random access procedure, the WAB-MT terminal will be able to establish a connection with the core network CN1. This process involves the exchange of RRC (Radio Resource Control) signaling to establish a DRB (Data Radio Bearer) and possible PDU sessions, thereby enabling data transmission.

[0163] In some optional embodiments of this application, a process is provided for a WAB-MT2 device to attempt to access WAB-gNB1. Specifically, the Mobile Access Device (MWAB) includes WAB-gNB1 and WAB-MT1, wherein WAB-MT1 is connected to the core network CN1 and its PLMN is 1; WAB-gNB1 is connected to the core network CN2 and its PLMN is 2. This embodiment describes an initial connection process of NCR-MT2 as follows:

[0164] 1. The second access control information set in the WAB-gNB1 broadcast message MIB: the cell prohibition indication information is set as follows:

[0165] cellBarred ENUMERATED{notBarred}.

[0166] The SIB message contains the first access control information settings: Mobile access device terminal device control information settings are as follows:

[0167] WAB-Support-r18 ENUMERATED{true}OPTIONAL,--Need S.

[0168] 2. After reading WAB-Support-r18, WAB-gNB2 determines that WAB-gNB1 cannot connect.

[0169] 3. The WAB-MT2 terminal believes that the WAB-gNB1 cannot access the network.

[0170] 4. Based on the list of selectable cells configured in the OAM, the WAB-MT2 terminal obtains cell 1 and cell 3 through measurement, and finally selects cell 1 with higher signal strength for access.

[0171] As some alternative embodiments of this application, an architecture for a mobile access device and its connected core network equipment and backhaul equipment are provided. Specifically, the mobile access device MWAB1 includes WAB-gNB1 and WAB-MT1, wherein WAB-MT1 is connected to the core network CN1 and PLMN is 1; WAB-gNB is connected to the core network CN2 and PLMN is 2. BH gNB2 is a base station for connecting to the mobile access device. MWAB2 includes WAB-gNB2 and WAB-MT2, wherein WAB-gNB2 and BH gNB2 are connected via an Xn interface, and WAB-MT1 currently resides in BH gNB2.

[0172] This embodiment describes the process of switching WAB-MT1 from BH gNB2 to WAB-gNB2, as follows:

[0173] 1. The second access control information set in the WAB-gNB2 broadcast message MIB: the cell prohibition indication information is set as follows:

[0174] cellBarred ENUMERATED{notBarred},

[0175] The SIB1 message contains the first access control information settings: Mobile access device terminal device control information settings are as follows:

[0176] WAB-Support-r18 ENUMERATED{true}OPTIONAL,--Need S.

[0177] 2. BH gNB2 sends a handover command message to WAB-MT1, which carries the SIB1 information of WAB-gNB2.

[0178] 3. When WAB-MT1 receives the handover command message, it determines that WAB-gNB2 cannot access the network based on WAB-Support-r18 in the SIB1 information.

[0179] 4. WAB-MT1 initiates the RRC connection reconstruction process, selecting cell 1 from the allowed cell list configured by OMC for reconstruction.

[0180] As can be seen from the above embodiments, compared with traditional NCR and IAB schemes, this application can effectively avoid multi-hop access and prevent multi-hops caused by mutual access between WAB, NCR, and IAB devices. This application clarifies that terminal devices in mobile access equipment should avoid switching to WAB or other base stations during handover, thereby supporting a multi-hop control mechanism during mobility and defining the terminal behavior of WAB-MT. Furthermore, this application does not involve any impact on terminals because it is a network-side solution with good forward compatibility and is easy to deploy and implement in the network.

[0181] This application embodiment also provides a terminal device, specifically: the terminal device obtains wireless access from a first base station device or a mobile access device, wherein the wireless access includes at least one of 4G, 5G, and 6G wireless access; the first base station device supports at least one of the following states: Radio Resource Control (RRC) connection state, RRC idle state, and RRC inactive state.

[0182] When a terminal device establishes a complete connection with the first base station or mobile access device and can exchange data, the terminal device is in RRC connected state. In this state, the terminal device can send and receive data and frequently interact with the base station to maintain connection continuity and quality of service. When there is no data transmission requirement, the terminal device can enter RRC idle state to conserve radio resources and battery power. In this state, the terminal device listens to the paging channel to respond quickly to incoming calls or data. In RRC inactive state, no data radio bearer is established between the terminal device and the first base station, but a certain level of connection information is retained to quickly restore the RRC connected state.

[0183] Preferably, the terminal device receives services in the mobile access device, the first base station device, or the second base station device without being aware of the network service.

[0184] During service reception, the terminal device does not need to explicitly know whether its service is provided by a mobile access device, a first base station device, or a second base station device. This non-awareness is based on advanced network management and optimization functions, such as network control repeaters, the use of WAB support indication information, and intelligent decision-making during RRC connection reconstruction. When performing cell selection, reselection, or handover, the terminal device makes decisions based on network configuration control information and signal strength parameters, without being aware of or needing to know the specific source and transmission path of the network service.

[0185] Preferably, the terminal device obtains broadcast messages or transmits and receives wireless signals from the cell belonging to the first base station device, wherein the wireless signals include at least one of 4G signaling and data, 5G signaling and data, and 6G signaling and data.

[0186] Broadcast messages, such as master information blocks and system information blocks, are sent by base stations via the downlink and contain critical information for network access and operation. This information helps terminal devices understand network configuration parameters, including cell ID, operating frequency band, bandwidth, control channel location, and access control information. In 4G / LTE networks, this information is sent via the PBCH (Physical Broadcast Channel) and PDSCH (Physical Downlink Shared Channel); in 5G / NR networks, it is sent via new broadcast and control channel formats.

[0187] In 4G / LTE networks, terminal devices establish a connection with the first base station device in a cell to send and receive signaling and data. Signaling includes connection establishment and release during the RRC (Radio Resource Control) process, as well as non-access stratum signaling; data transmission is handled through the user plane packet data aggregation protocol, radio link control, and media access control layers. LTE uses Orthogonal Frequency Division Multiple Access (OFDMA) and Single-Carrier Frequency Division Multiple Access (SCDMA) technologies for data transmission.

[0188] In 5G / NR networks, inter-cell communication between terminal devices and the first base station employs technologies such as massive MIMO and millimeter-wave frequency band transmission to support higher data rates and lower latency. The signaling and data transmission mechanisms are similar to 4G, but NR networks allow for more flexible resource allocation and scheduling strategies to adapt to different service requirements, such as enhanced mobile broadband, massive machine-type communications, and URLLC (Ultra-Reliable Low-Latency Communications) services.

[0189] Preferably, the terminal device completes the connection with the core network or data transmission and reception through the connection established between the mobile access device, the first base station device, or the second base station device and the core network.

[0190] For example, a terminal device completes its connection with the core network or data transmission and reception through a connection established between a mobile access device and the core network; a terminal device completes its connection with the core network or data transmission and reception through a connection established between a first base station device and the core network; a terminal device completes its connection with the core network or data transmission and reception through a connection established between a second base station device and the core network. Here, the first base station device is a device within the mobile access device, and the second base station device may or may not be a device within the mobile access device.

[0191] Preferably, when the terminal device is in RRC idle state, it supports cell reselection or cell selection between cells or within cells managed by base station equipment in ordinary cells or mobile access equipment.

[0192] For example, when the terminal device is in RRC idle state, it supports cell reselection or cell selection in ordinary cells; when the terminal device is in RRC idle state, it supports cell reselection or cell selection between cells managed by the base station equipment in the mobile access equipment; when the terminal device is in RRC idle state, it supports cell reselection or cell selection within cells managed by the base station equipment in the mobile access equipment.

[0193] Preferably, the terminal device is not a terminal device within a mobile access device. The mobile access device includes a first terminal device and at least one base station device, including a first base station device. In other words, the mobile access device is composed of a terminal portion and base station devices, wherein the base station devices at least encompass the first base station device and may also include other base station devices, and the terminal portion encompasses the first terminal device. Alternatively, the mobile access device consists of a first terminal device and one or more base station devices, where the base station devices at least include the first base station device. The mobile access device is deployed on a moving or stationary object to provide services to terminal devices located inside or outside the object.

[0194] Preferably, the terminal device obtains the broadcast message from the first base station device or the second base station device and ignores the first access control information.

[0195] The first access control information includes access control information for at least one cell and / or mobile access equipment terminal equipment control information for at least one cell; the access control information includes at least one of the following: network control repeater (NCR) support indication information, integrated access and backhaul (IAB) support indication information.

[0205] In some alternative embodiments, the first access control information is configured at the granularity of each public land mobile network (PLMN), or each independent non-public network (SNPN), or all PLMNs, or all SNPNs.

[0210] In a wireless communication system, the establishment of an IP connection for the backhaul link between the first base station device and the first terminal device means that a direct communication channel is established between them through a network layer protocol (such as IP) for transmitting control plane and user plane data. Through the first interface, the first terminal device can obtain real-time status information of the first base station device. This includes, but is not limited to, the base station's carrier state, signal quality (such as RSRP, RSRQ), cell load, number of connected terminals, and backhaul link quality.

[0211] Preferably, when the first terminal device is in an RRC inactive state, the first base station device continues to receive and / or transmit wireless signals.

[0212] When the first terminal device transitions from the RRC connected state to the RRC idle state, the first base station device stops receiving and / or transmitting wireless signals, and / or deletes the interface information between the first base station and the core network.

[0213] When the first terminal device transitions from the RRC connected state to the RRC inactive state, the first base station device continues to receive and / or transmit wireless signals, and / or deletes the interface information between the first base station and the core network.

[0239] Preferably, when the first terminal device 61 transitions from the RRC connected state to the RRC idle state, the first base station device 621 stops receiving and / or transmitting wireless signals.

[0240] In other words, when the first terminal device 61 transitions from an RRC connected state to an RRC idle state, the first terminal device 61 stops receiving wireless signals from the first base station device 621, and / or stops sending wireless signals to the first base station device 621.

[0247] When the first terminal device 61 is in RRC connected state, the serving cell it connects to is the cell for which the network provides data transmission, control information exchange, and radio resource scheduling. The serving cell is the direct environment in which the terminal device performs normal communication activities, including uplink data transmission, downlink data reception, handover control, and quality monitoring. In RRC idle state, the first terminal device 61 camps in a certain cell. Although it does not transmit data with the network, it still listens for system information broadcasts to receive paging messages or perform cell reselection. When the first terminal device 61 moves within the serving cell, approaching or crossing the cell boundary, neighboring cells become potential handover targets or candidate cells. The network monitors the signal strength and quality between the terminal device and neighboring cells to determine whether and when to perform cell handover, ensuring communication continuity and service quality for the terminal device. In RRC idle state, the first terminal device 61 may consider moving from its current camped cell to a neighboring cell, for example, for cell reselection.

[0255] For example, if the first access control information is sent by a broadcast message from the first base station device 621, and the first access control information includes access control information for one cell, then the network determines that the first terminal device 61 is prohibited from accessing the target cell. If the first access control information and the second access control information are sent by a broadcast message from the first base station device 621, and the first access control information includes access control information for two cells, then the network determines that the first terminal device 61 is prohibited from accessing the target cell. If the first access control information, the second access control information, and the access cell restriction list are sent by a broadcast message from a cell in the second base station, and the first access control information includes access control information for three cells, then the network determines that the first terminal device 61 is prohibited from accessing the target cell.

[0257] For example, if the second access control information includes unified access control configuration information, the first terminal device 61 ignores the cell prohibition indication information and the cell reservation information used for the current operation. Alternatively, if the second access control information includes unified access control configuration information, the first terminal device 61 ignores the cell prohibition indication information, the cell reservation information used for the current operation, the cell reservation information used for future use, and the cell reservation information used for a preset purpose.

[0258] Preferably, the access cell restriction list is obtained through the Operation, Management, and Maintenance (OAM) configuration of the network management system. The first terminal device 61 is configured to allow access to the cell list and / or prohibit access to the cell list; when the OAM configuration of the network management system is a candidate list for cell reselection, the first terminal device 61 is configured to allow access to the cell list; when the OAM configuration of the network management system is not a candidate list for cell reselection, the first terminal device 61 is configured to refuse to use cells in the prohibition list as cells for reselection.

[0259] Preferably, the first terminal device 61 determines whether the network prohibits or allows the first terminal device 61 to access the target cell, which can be achieved by the following method: If the first terminal device 61 is a network control repeater mobile terminal device NCR-MT or an integrated access and backhaul mobile terminal device IAB-MT, and the first access control information and / or the second access control information and / or the access cell restriction list are sent by a broadcast message from the first base station device 621 or by a broadcast message from a cell in the second base station, and the first access control information includes mobile access device terminal device control information, the first terminal device 61 determines that the network prohibits the first terminal device 61 from accessing the target cell.

[0260] For example, if the first terminal device 61 is a Network Control Repeater Mobile Terminal Device (NCR-MT), and the first access control information is sent by a broadcast message from the first base station device 621, and the first access control information includes mobile access device terminal device control information, then the first terminal device 61 determines that the network prohibits the first terminal device 61 from accessing the target cell. Alternatively, if the first terminal device 61 is an Integrated Access and Backhaul Mobile Terminal Device (IAB-MT), and the first and second access control information are sent by a broadcast message from a cell in the second base station, and the first access control information includes mobile access device terminal device control information, then the first terminal device 61 determines that the network prohibits the first terminal device 61 from accessing the target cell.

[0261] In some optional embodiments of this application, the first access control information and / or the second access control information and / or the access cell restriction list are sent by the RRC message of the first base station device 621, or by the RRC message of the second base station, wherein the first base station device 621 is a base station device 62 in the mobile access device, and the base station portion of the mobile access device includes at least one base station device 62, including the first base station device 621; the second base station is a base station device 62 in the mobile access device, or the second base station is not a base station device 62 in the mobile access device; the RRC message is a handover command message or an RRC reconfiguration message.

[0262] It is understandable that the second base station, which may be located inside or outside the mobile access equipment, may also send the first access control information and / or the second access control information and / or the access cell restriction list to the first terminal equipment 61 through its broadcast channel.

[0263] Preferably, when the RRC message includes mobile access device terminal control information, the first terminal device 61 selects another cell for access or attempts to access during the RRC connection reconstruction process.

[0264] Preferably, if the RRC message does not include mobile access device terminal equipment control information, the mobile access device terminal equipment control information is searched in the broadcast message of the first base station device 621 or in the broadcast message of the cell in the second base station; if the mobile access device terminal equipment control information is searched in the broadcast message of the first base station device 621 or in the broadcast message of the cell in the second base station, the RRC connection reconstruction process of the first terminal device 61 is triggered.

[0265] Preferably, during the RRC connection reconstruction process, the first terminal device 61 instructs the first base station device 621 to stop providing services to the first terminal device 61.

[0266] Preferably, after accessing the first network, the first terminal device 61 establishes a first connection with the first network, wherein the first connection includes at least one of: a Protocol Data Unit (PDU) session between the second base station and the first network, a Data Radio Bearer (DRB) between the first terminal device 61 and the second base station, and a Transmission Control Protocol (TCP / IP) connection between the first terminal device 61 and the first network; the first base station device 621 establishes a second connection with the second network on the first connection; the first network and the second network are the same core network or different core networks; the second connection is the connection between the control plane and the user plane of the first base station device 621 and the second network.

[0267] The establishment of a PDU session signifies that the network has allocated a specific IP address and user plane path to the first terminal device 61, enabling it to conduct data communication over the network. Once the first terminal device 61 accesses the network and establishes a PDU session, a DRB will be established between it and the second base station to support uplink and downlink data transmission. The establishment and management of the DRB are handled by the network's RRC layer, dynamically adjusted based on network resource availability and the terminal device's quality of service requirements.

[0268] The first base station device 621 (part of the mobile access device) not only establishes a connection with the first network (core network), but may also establish a second connection with a second network (which may be another part of the same core network or a completely different core network) based on the first connection. This second connection refers to the connection between the control plane and the user plane, where the control plane connection is used to transmit control information, such as handover commands and configuration updates, while the user plane connection is used for data transmission. The establishment of the second connection may be to resolve data forwarding between multiple core network domains, or to support flexible operation of the mobile access device between different core network domains.

[0269] As can be seen from the above embodiments, compared with traditional NCR and IAB schemes, this application can effectively avoid multi-hop access and prevent multi-hops caused by mutual access between WAB, NCR, and IAB devices. This application clarifies that terminal devices in mobile access equipment should avoid switching to WAB or other base stations during handover, thereby supporting a multi-hop control mechanism during mobility and defining the terminal behavior of WAB-MT. Furthermore, this application does not involve any impact on terminals because it is a network-side solution with good forward compatibility and is easy to deploy and implement in the network.

This configuration affects all terminal devices within the PLMN, providing a unified access control standard. Similarly, the network can also configure first access control information applicable to all SNPNs. This configuration affects all terminal devices within the SNPN, providing a unified access control standard.

The mobile access device is deployed on a moving or stationary object to provide services to terminal devices located inside or outside the object.

[0279] In other words, an IP connection is established between the first terminal device and the first base station device via a backhaul link. This means that a direct communication channel is established between the two through a network layer protocol (such as IP) for transmitting control plane and user plane data.

[0280] Preferably, the target cell includes: a cell that sends broadcast messages or RRC messages, at least one of the following: the cell where the first terminal device is camped in the RRC idle state, the handover cell, and the neighboring cell; the air interface technology of the target cell is 5G or a subsequent evolution technology.

[0281] In other words, the target cell uses a 5G-based wireless air interface technology standard, specifically, it follows the 5G NR technical specifications developed by 3GPP or future evolution versions.

[0282] According to some alternative embodiments of this application, the first access control information and / or the second access control information and / or the access cell restriction list are sent by a broadcast message from the first base station device, or by a broadcast message from a cell in the second base station, wherein the first base station device is a base station device in a mobile access device, and the base station portion of the mobile access device includes at least one base station device, including the first base station device; the second base station is a base station device in the mobile access device, or the second base station is not a base station device in the mobile access device.

[0287] For example, if the first access control information is sent by a broadcast message from the first base station device, and the first access control information includes access control information for one cell, then the network determines that the first terminal device is prohibited from accessing the target cell. If the first access control information and the second access control information are sent by a broadcast message from the first base station device, and the first access control information includes access control information for two cells, then the network determines that the first terminal device is prohibited from accessing the target cell. If the first access control information, the second access control information, and the access cell restriction list are sent by a broadcast message from a cell in the second base station, and the first access control information includes access control information for three cells, then the network determines that the first terminal device is prohibited from accessing the target cell.

[0288] Preferably, if the second access control information includes unified access control configuration information, the first terminal device ignores at least one of the following: cell prohibition indication information, cell reservation information for current operation, cell reservation information for future use, and cell reservation information for preset purpose.

[0305] In a wireless communication system, the establishment of an IP connection for the backhaul link between the first base station device and the first terminal device means that a direct communication channel is established between them through a network layer protocol (such as IP) for transmitting control plane and user plane data. Through the first interface, the first terminal device can obtain real-time status information of the first base station device. This includes, but is not limited to, the base station's carrier state, signal quality (such as RSRP, RSRQ), cell load, number of connected terminals, and backhaul link quality.
