Description

Technical Field

[0001] The embodiments of the present application relate to the field of communication technologies.

Background Art

[0002] Compared with conventional 3G (3rd generation mobile communication technology) and 4G (4th generation mobile communication technology) systems, the 5G (5th generation mobile communication technology) system can provide a larger bandwidth and a higher data rate, and can support more types of terminals and vertical services. Therefore, the allocated frequency of the 5G system is usually significantly higher than that of 3G and 4G systems. For example, the 5G system can be allocated to the millimeter wave band.

[0003] However, the higher the carrier frequency, the more serious the attenuation that the signal encounters in the transmission process. Therefore, in the actual allocation of the 5G system, especially in the millimeter wave band, how to better enhance the cell coverage is a problem waiting to be solved.

[0004] It should be noted here that the introduction of the above technical background is only for the purpose of briefly and clearly explaining the technical solutions of the present application and helping those skilled in the art to understand. It cannot be recognized that the above technical solutions are known to those skilled in the art only by the description in the background art part of the present application.

Summary of the Invention

[0005] To better address coverage issues in the actual allocation of cellular mobile communication systems, employing RF relays / repeaters to amplify and forward communication signals between terminal and network equipment is a relatively common allocation method. RF relays are widely used in the actual allocation of 3G and 4G systems. Typically, an RF relay is a device that amplifies and forwards incoming and outgoing signals between network and terminal equipment in the radio frequency band.

[0006] Regarding the coverage issues encountered in the allocation of 5G systems, employing radio frequency repeaters to enhance coverage is one viable solution. However, conventional repeaters lack the ability to communicate with network equipment and cannot obtain relevant uplink / downlink configuration information from network equipment locations. Therefore, while allocating such repeaters in a 5G system may help to enhance signal strength, they cannot flexibly adapt to complex environmental changes and cannot achieve the same effect as the same radio frequency repeaters allocated in 3G and 4G systems.

[0007] A smart repeater is an enhancement to conventional radio frequency repeaters, possessing the ability to receive and process side control information from the network. This side control information can be amplified and transmitted more efficiently by the smart repeater. As a result, it reduces unnecessary noise amplification, enables better spatially directional transmission and reception, and simplifies network integration.

[0008] However, the inventor discovered that, in the scenario of allocating smart repeaters, there is currently no research on how to perform admission control for smart repeaters.

[0009] Regarding at least one of the above problems, the present embodiment provides an admission control method and apparatus, and a communication system.

[0010] Based on one aspect of the embodiment of the present invention, an admission control device for application to a repeater is provided, which is: A first receiving unit that receives a first message relating to admission control, wherein the first message may or may not include first information, and Includes a first processing unit that ignores the first information and / or skips the first processing related to the admission control and / or performs the second processing related to the admission control.

[0011] Based on another aspect of the embodiment of the present invention, an admission control device for application to network equipment is provided, which is: A first transmitting unit that transmits a first message relating to admission control to a repeater, wherein the first message includes first information, and the first information is a specific value, or the first message does not include the first information. or Includes a first transmitting unit that does not send a first message regarding admission control to the repeater, or The device is A second receiving unit that receives the second message transmitted by the repeater, It includes a second processing unit that processes requests relating to the second message at a high priority level.

[0012] Based on another aspect of the embodiment of the present invention, a communication system is provided which includes network equipment and / or repeaters, wherein the repeaters include admission control devices of the one aspect, and the network equipment includes admission control devices of the other aspect.

[0013] One beneficial effect of the embodiment of the present invention is that, because the repeater ignores the first information contained in the first message relating to admission control and / or skips the first processing relating to admission control and / or performs the second processing relating to admission control, the repeater does not need to be controlled by the existing admission control mechanism, thereby mitigating network congestion and reducing allocation costs.

[0030] In the following, the scenes of the embodiments of this application will be described through the examples provided, but this application is not limited to those examples.

[0031] Figure 1 is a schematic diagram of one application scene in the embodiment of the present invention. As shown in Figure 1, for the sake of explanation, one network device (e.g., 5G base station gNB or gNB-CU) 101, one repeater 102, and one terminal device (UE) 103 are used as examples, but the present invention is not limited thereto. As shown in Figure 1, the terminal device 103 establishes a connection with the network device 101 and communicates with it. To improve the quality of communication, the signals between the terminal device 103 and the network device 101 are processed via the repeater 102 (e.g., amplification).

[0032] As shown in Figure 1, the system receives, processes, and transmits radiated or conducted RF carrier waves in both the downstream (from network equipment to terminal equipment) and upstream (from terminal equipment to network equipment) directions. This processing includes output amplification, beamforming, and propagation environment reshaping. If only the operating bandwidth of the downlink or uplink is specified, only the specified uplink or downlink will be repeated.

[0033] Figures 2 and 3 are schematic diagrams showing how repeaters transmit and receive signals. As shown in Figure 2, the repeaters include repeaters with omnidirectional or fixed-directional (non-self-adaptive over time) Tx / Rx or self-adaptive over time capabilities. As shown in Figure 3, the beam for transmitting radio frequency signals is controlled by network equipment (e.g., RAN nodes).

[0034] In the embodiments of this invention, the transmission of existing or future tasks can be carried out between network equipment and terminal equipment. For example, these tasks may include, but are not limited to, enhanced mobile broadband (eMBB), massive machine-type communications (mMTC), low-latency, high-reliability communications (URLLC), and vehicle-to-everything (V2X) communications.

[0035] Figure 1 illustrates an example where a repeater can transfer signals between network equipment and terminal equipment, but the present invention is not limited to this. For example, the repeater can act as a second device, transferring signals between the first and third devices, and can also communicate directly with the first and / or third devices, and the first to third devices can be any devices in the network. In the following embodiment, the case where the first device is network equipment and the third device is terminal equipment will be described as an example.

[0036] In the embodiments of this invention, the beam can be expressed as a lobe, reference signal (RS), transmission configuration indication (TCI), spatial domain filter, etc. Alternatively, it can be expressed as a beam index, lobe index, reference signal index, transmission configuration indication index, spatial domain filter index, etc. The reference signals mentioned above include, for example, channel status information reference signals (CSI-RS), detection reference signals (SRS), RS for use by repeaters, and RS transmitted by repeaters. The TCI mentioned above can also be expressed as TCI state.

[0037] In the embodiments of the present invention, a repeater can be further described as a network-controlled repeater (NCR), a reconfigurable intelligent surface (RIS), a repeater station, a radio frequency repeater, a transponder, a radio frequency transponder, or a repeater station node, a repeater node, a repeater node, or even a smart repeater station, a smart repeater, a smart repeater, a smart repeater station node, a smart repeater node, a smart repeater node, etc., and a repeater can be a single type of node, device, or entity, but the present invention is not limited to these.

[0038] In the embodiments of this application, the network device may be a device in the service cell of the terminal device, a device in the cell where the repeater is located, a device in the service cell of the repeater, or the parent node of the repeater. This application does not impose any restrictions on the name of the repeater, and any device capable of realizing the above functions is included within the scope of a repeater in this application.

[0039] Currently, considering issues such as network congestion, NG-RAN supports overload and admission control functions, including a backoff mechanism in the random access process, radio resource control (RRC) connection denial, RRC connection release, and terminal device-based access prohibition mechanisms.

[0040] For example, in a random access process, a terminal device may receive a backoff instruction, and the backoff mechanism is applied to a competition-based random access process. The backoff instruction specifies a time range that the terminal device should wait before re-selecting a random access resource and / or sending a random access preamble code. In response to the backoff instruction, the terminal device obtains a PREAMBLE_BACKOFF value and multiplies it by the coefficient SCALING_FACTOR_BI to select a random value between 0 and PREAMBLE_BACKOFF × SCALING_FACTOR_BI. If the random access is unsuccessful, it waits for the specified random value time before selecting and / or confirming the random access resource and / or random access preamble code, and then sends the selected / confirmed random access preamble code to the confirmed random access resource.

[0041] For example, in a random access process, terminal devices send a Radio Resource Control (RRC) establishment or recovery request to the network side, which contains the establishment or recovery cause. Based on this cause, the network side can decide whether to accept the request. If the network side accepts the request, it can send an RRC establishment message or an RRC recovery message; otherwise, it replies with an RRC rejection message. By receiving or rejecting these RRC establishment or recovery requests, the network side can control congestion.

[0042] Figure 4 is a schematic diagram of the process by which a terminal device attempts to establish a new connection from an RRC idle state. As shown in Figure 4, at 401, the terminal device sends an RRC establishment request (RRCSetupRequest) to the network device. At 402, the network device determines that it cannot process the request (for example, due to network congestion), and at 403, the network device sends an RRC rejection message (including a waiting period), keeping the terminal device in an RRC idle state.

[0043] Figure 5 is a schematic diagram of the method by which a terminal device attempts to recover its connection from an RRC deactivated state. As shown in Figure 5, in 501, the terminal device sends an RRC recovery request (RRCResumeRequest) to the network device. In 502, the network device determines the reason why it cannot process the request (for example, network congestion). In 503, the network device sends an RRC rejection message (including a waiting period) and keeps the terminal device in an RRC deactivated state.

[0044] Network devices prioritize establishment causes as "emergency," "mps-Priority Access," and The system will treat these access attempts as "mcs-Priority Access" (i.e., emergency calls, MPS, and MCS users) and will only return a connection denial message to these access attempts under extreme network load conditions that could threaten the stability of network equipment.

[0045] For example, RRC connection release is typically performed by network equipment, and the purpose of the RRCRelease process is to release the RRC connection, which includes releasing established radio bearers and returning the radio link control (BH LRC) channel and radio resources.

[0046] The RRC connection release process can be used to reorient one NR frequency or one E-UTRA carrier frequency from terminal equipment. The reorientation mechanism during RRC release can be used to achieve load balancing within the NR.

[0047] Figure 6 is a schematic diagram of the RRC connection release method, and as shown in Figure 6, at 601, the network device sends an RRC release message to the terminal device.

[0048] For example, a terminal-based access denial mechanism is used in a unified access control process / mechanism / architecture, namely a terminal-based access denial mechanism. The network side can broadcast admission control parameters, and based on these parameters, which are applied to the appropriate access level for the access attempt, network equipment checks whether or not to actually perform the access attempt. The unified access control mechanism can be applied to user equipment accessing the 5G core network using an evolved universal mobile telecommunications system (UMTS), Evolved UMTS Terrestrial Radio Access (E-UTRA), or NR. Furthermore, the mechanism can be applied to situations when idle, deactivated, or connected user equipment issues a new access attempt (e.g., a new session request, e.g., before sending MSG3, before sending a connection request message, or before sending a connection recovery request message).

[0049] NG-RAN broadcasts admission control parameters associated with Access Categories and Access IDs (if the network is shared, admission control parameters can be set individually for each overwave public mobile communication network (PLMN)).

[0050] Based on the selected PLMN, the access class selected for the access attempt, and the prohibition information for broadcasting the access ID, the terminal device determines whether or not it is authorized to attempt access. For requests that excite the non-access layer (NAS, upper layer), the NAS determines the access class and access ID. For requests that excite the access layer (AS), the RRC determines the access class, and at the same time, the NAS determines the access ID.

[0051] The inventors discovered that, in scenarios where smart repeaters are assigned, there is currently no research into how to implement admission control for smart repeaters. The inventors recognize that since repeaters do not perform actual tasks, they do not cause network congestion, and therefore do not need to be controlled by an admission control mechanism. Furthermore, after a repeater accesses the network, it can provide better wireless quality to cell edge terminal equipment, increasing resource utilization, reducing the resources required for transmission, and effectively mitigating network congestion, which also explains why repeaters do not need to be controlled by an admission control mechanism.

[0052] The inventors discovered that if the repeater were to follow the access control mechanism of existing terminal devices, it would be subject to the control of the admission control mechanism, potentially preventing it from accessing the network, limiting its application scenarios, and increasing allocation costs.

[0053] The above issues will be explained below based on various embodiments of the present invention. These embodiments are illustrative and not limitations to the present invention.

[0054] Example of the first aspect In this embodiment, an admission restriction (also known as access control) method is provided, which will be described starting with the terminal equipment.

[0055] Figure 7 is a schematic diagram of one admission restriction method in the embodiment of the present invention, and as shown in Figure 7, the method is 701, the relay receives a first message relating to admission control, and the first message may or may not contain first information. 702, the relay device ignoring the first information and / or skipping the first processing relating to the admission control and / or performing the second processing relating to the admission control.

[0056] Through the embodiments of the present invention, by having the repeater ignore first information contained in a first message relating to admission control, and / or skip a first process relating to admission control, and / or perform a second process relating to admission control, the repeater is not subject to the control of the existing admission control mechanism, thereby mitigating network congestion and reducing allocation costs. The phrase "not subject to control" above can be replaced with "not apply / applicable," "not use," "ignore," "skip," etc., and the embodiments of the present invention are not limited to such replacements.

[0057] Existing admission control mechanisms mainly include backoff mechanisms in random access processes, denial of radio resource control (RRC), release of RRC, and unified access control procedures. The behavior of repeaters in each of the above admission control mechanism scenarios will be described below, but the first message related to admission control is the first message in the admission control process described above.

[0058] (1) Backoff mechanism in random access processes In a series of embodiments, the random access process can be a conventional competition-based random access process, and may include two interactions (4-step RA) between the network device and the terminal device. In the first interaction, the terminal device issues a random access request (MSG1) and the network device receives a feedback random access response (MSG2). In the second interaction, the terminal device sends information including a user identifier to the network device (MSG3) and the network device receives a feedback MSG4. Alternatively, the random access process may be a two-step random access process (2-step RA), where the existing MSG1 and MSG3 are merged into a new MSGA, and MSG2 and MSG4 are merged into an MSGB. Specific details can be found in existing technologies, so they will not be described in further detail here.

[0059] In a series of embodiments, the first message may include a random access response RAR or MSGB from MSG2, and the first information may include backoff instruction-related information, for example, the backoff instruction-related information may be a MAC subhead carrying a backoff instruction field. The value of the backoff instruction field may be considered an index value of a single backoff parameter, that is, the backoff instruction field is used to indicate a single backoff parameter value, which indicates a time range that must be waited before issuing the random access preamble code again. In 701, "receive" in the sense that the repeater receives the first message relating to admission control may be further replaced with "detect," "received," or "attempt to receive," that is, "receive" here may indicate that the repeater has performed the action of receiving (detecting) the first message, but does not indicate success or failure of reception, that is, the repeater may have received the first message, or it may have attempted to receive the first message but was unsuccessful, and this embodiment of the present invention does not limit this.

[0060] In a series of embodiments, before transmitting the first message, the network device can distinguish between terminal devices and repeaters, in which case the RAR or MSGB may or may not contain backoff instruction-related information, and the value of the backoff instruction field carried in the backoff instruction-related information is a specific value, which can be one specific value other than 0 to 13, and the backoff parameter value corresponding to the specific value (index) is 0 (ms), for example, the specific value can be 14 or 15, but is not limited to this in the embodiments of this application.

[0061] For example, if the first message is a RAR, then the RAR either does not contain a MAC subhead (sub-PDU) carrying a backoff indicator field, or the RAR contains a MAC subhead (sub-PDU) carrying a backoff indicator field, but the value of the backoff indicator field is that specific value.

[0062] For example, if the first message is an MSGB, the MSGB does not necessarily have to include a MAC subhead (sub-PDU) carrying a backoff indicator field. For instance, the value of the T1 field in the MSGB might be 1 (indicating that the MAC subhead contains a random access preamble code but not the T2 field, i.e., the BI field is not included), or the value of the T1 field in MSGB1 might be 0 but the value of the T2 field might be 1 (indicating that the MAC subhead contains a MAC SDU indicator but not the backoff indicator field).

[0063] For example, if the first message is an MSGB, the MSGB may include a MAC subhead (sub-PDU) carrying a backoff indicator field, for example, the value of the T1 field in MSGB1 is 0, the value of the T2 field is 0 (indicating that the MAC subhead contains a backoff indicator field), but the value of the backoff indicator field is the specified value.

[0064] According to the above embodiment, since the first message does not contain backoff instruction-related information, or the value of the backoff instruction field is a specific value (corresponding to the backoff parameter value being 0 (ms)), in 702, after receiving the first message, the repeater skips the first processing related to admission control. For example, since backoff (waiting) is not required and the backoff mechanism in the random access process is not controlled, network congestion can be mitigated and allocation costs can be reduced.

[0065] In a series of embodiments, before sending the first message, the RAR or MSGB may include backoff instruction-related information, regardless of whether the network equipment can distinguish between terminal equipment and repeaters. In 702, the repeater ignoring the backoff instruction and / or skipping the first processing related to the admission control includes setting PREAMBLE_BACKOFF to 0. In other words, regardless of the value of the backoff instruction, the repeater does not need to look up and obtain the PREAMBLE_BACKOFF value corresponding to the BI, but directly sets PREAMBLE_BACKOFF to 0. Therefore, the repeater does not need to delay the random access resource selection process, or it can set its waiting time to 0 and execute the random access resource selection process without being controlled by the backoff mechanism in the random access process, thus mitigating network congestion and reducing allocation costs.

[0066] In a series of embodiments, if the reception of the first message is unsuccessful in 701, the first processing related to admission control (including the random access resource selection process) is skipped in 702. For example, if the reception of the RAR is unsuccessful and the random access process is not achieved, the repeater (immediately) executes the random access resource selection process. Therefore, since the repeater is not subject to the control of the backoff mechanism in the random access process, network congestion can be mitigated and allocation costs can be reduced.

[0067] In a series of embodiments, the repeater receives the RAR in a random access response reception time window (ra-Response Window, or msgB-Response Window), which can be configured in the beam failure recovery configuration BeamFailureRecoveryConfig or the random access public configuration RACH-ConfigCommon transmitted by the network equipment (determined depending on the excitation cause of the random access; for example, if it is a random access with beam failure recovery excitation, the ra-Response Window configured by BeamFailureRecoveryConfig is used), and the unsuccessful reception of the RAR includes at least one of several situations:

[0068] If the ra-ResponseWindow configured in BeamFailureRecoveryConfig exceeds the time limit, and the service cell transmitting the random access preamble does not receive a PDCCH transmission in the search space indicated by the Cell Radio Network Temporary Identifier (C-RNTI) which specifies the address, and the Recovery Search Space Identifier (recoverySearchSpaceId, the search space configured by the network equipment for beam failure to recover RAR), then, if the random access process is not completed, the repeater (immediately) executes the random access resource selection process. Or, If the ra-ResponseWindow configured in RACH-ConfigCommon exceeds the time limit and the RAR containing a random access preamble code matching the transmitted random access preamble index PREAMBLE_INDEX has not been received (for example, if the RAPID indicated by the random access preamble does not match PREAMBLE_INDEX), and the random access process is not completed, the relay will (immediately) execute the random access resource selection process. Or, If the random access response reception time window (msgB-ResponseWindow) exceeds the time limit, and the random access response reception has not yet been recognized as successful, and the MSGA maximum number of transmissions (msgA-TransMax) is not applied, or the random access preamble transmission count counter (PREAMBLE_TRANSMISSION_COUNTER) is not equal to msgA-TransMax+1, then, if the random access process is not completed, the repeater (immediately) executes the random access resource selection process for a 2-step RA type random access. Or, If competitive resolution is deemed unsuccessful, and the random access process is not completed, the relay will (immediately) execute the random access resource selection process. For example, if the random access type RA_TYPE is set to 4-step RA, the relay will (immediately) execute the random access resource selection process; otherwise (i.e., RA_TYPE is set to 2-step RA), the relay will (immediately) execute the random access resource selection process for 2-step RA type random access.

[0069] (ii) RRC rejection In a series of embodiments, prior to 701, when the repeater attempts to establish a new connection in an RRC idle state and / or attempts to recover a connection in an RRC deactivated state, it sends a second message to the network, which includes an RRC establishment request or an RRC recovery request. At 701, the network device sends a first message to the repeater, which includes an RRC rejection message, which includes a waitTime, which indicates the duration of Timer T302, and which is used to indicate the wait time for the repeater to initiate the next RRC connection establishment / recovery flow.

[0070] In a series of embodiments, since the RRC rejection message does not include a waiting time, in 702, after receiving the first message, the repeater skips the first processing related to the admission control and immediately performs the next RRC connection establishment / recovery process without the need to activate T302 (or set T302 to 0), i.e., without waiting. Since it is not subject to the control of the waiting time in the RRC rejection message, network congestion can be alleviated and allocation costs can be reduced.

[0071] In a series of embodiments, the RRC rejection message may include a waiting time, the numerical range of the waiting time is [1,16] (example, not including 0), and in 702, the repeater ignoring the waiting time and / or skipping the first processing relating to the admission control includes setting the waiting time to 0, that is, regardless of the value of the waiting time, the repeater does not always need to be controlled by the waiting time, and the repeater does not need to activate T302 (or set T302 to 0), so the repeater does not need to delay and immediately performs the next RRC connection establishment / recovery flow, or the repeater performs the next RRC connection establishment / recovery flow with a waiting time of 0 and is not controlled by the waiting time in RRC rejection, thus mitigating network congestion and reducing allocation costs.

[0072] In a series of embodiments, the RRC rejection message may also include a waiting time, and the numerical range for the waiting time is [0, 16] (example, including 0). If the adopted numerical value for the waiting time is not 0, the operation is performed as described above. If the adopted numerical value for the waiting time is 0, then in 702, the repeater ignores the waiting time and / or skips the first processing related to the admission control, which includes setting the waiting time to 0, and / or performs the second processing related to the admission control, which includes setting T302 to 0. The repeater then immediately performs the next RRC connection establishment / recovery flow, i.e., the waiting time can be set to 0. Therefore, the repeater does not need to delay and immediately performs the next RRC connection establishment / recovery flow, or the repeater performs the next RRC connection establishment / recovery flow with a waiting time of 0 and is not subject to waiting time control in RRC rejection, thus mitigating network congestion and reducing allocation costs.

[0073] (3) RRC release In a series of embodiments, in 701, the network device sends a first message to the repeater, which includes an RRC release message, which includes a wait time waitTime, which indicates the duration of timer T302, which is used to indicate the wait time for the repeater to perform the next RRC connection establishment flow, during which access attempts are prohibited.

[0074] In a series of embodiments, since no waiting time is included in the RRC release message, in 702, after the repeater receives the first message, it skips the first processing related to the admission control, which includes the fact that the repeater does not need to activate T302 (or set T302 to 0). As a result, the repeater attempts access immediately without the need for waiting time and is not subject to waiting time control in the RRC release, thus mitigating network congestion and reducing allocation costs.

[0075] In a series of embodiments, the RRC release message may also include a waiting time, the numerical range of the waiting time [1,16] (exemplary, not 0), and in 702, the repeater ignoring the waiting time and / or skipping the first processing relating to the admission control includes setting the waiting time to 0, meaning that regardless of the value of the waiting time, the repeater does not always need to be controlled by the waiting time, and the repeater does not need to activate T302 (or set T302 to 0), so the repeater can attempt access without waiting, and since it is not subject to waiting time control in the RRC release, network congestion can be mitigated and allocation costs can be reduced.

[0076] In a series of embodiments, the RRC release message may also include a waiting time, the numerical range of the waiting time being [0, 16] (example, including 0), and if the adopted numerical value for the waiting time is not 0, the operation is performed as described above; if the adopted numerical value for the waiting time is 0, then in 702, the repeater ignores the waiting time and / or skips the first processing related to the admission control, which includes setting the waiting time to 0 and / or performing the second processing related to the admission control, which includes setting T302 to 0, the repeater can attempt access without waiting, and is not subject to waiting time control in the RRC release, thus mitigating network congestion and reducing allocation costs.

[0077] (iv) Unified access control process In a series of embodiments, the first message includes system information (e.g., SIB1) broadcast by a network device, the first information includes admission control parameters, the admission control parameters are associated with an access level and an access ID, the admission control parameters may include at least one of UAC-BarringInfoSetList, UAC-BarringPerCatList and UAC-BarringPerPLMN-List, the admission control parameters include a barring time (uac-BarringTime) and / or a barring factor (uac-BarringFactor), the barring factor is used for comparison with a random number to determine whether an access attempt is permitted or not, the barring time is used to calculate the duration of timer T390 (corresponding to the access level), and the admission control parameters can be configured individually for each PLMN.

[0078] For example, multiple access levels can be defined in advance, such as AC0 to AC30 in the standard definition and AC31 to AC63 in the provider definition. Multiple access levels can correspond to one established cause value, for example, AC0 to AC3 correspond to cause value 1, AC4 to AC10 correspond to cause value 2, and so on. However, this application is not limited to these, and access levels and established cause values ​​can be defined according to actual needs.

[0079] For example, the access ID indicates the configuration being provided, with a numerical range of 0 to 15. 0 indicates no parameters are configured, 1 indicates that MPS (Multimedia Priority Service) is configured, 2 indicates that MCS (Mission Critical Service) is configured, 3 indicates a UE to which disaster conditions apply, 4-10 are reserved, and 11-15 indicate that the configured access level is 11-15.

[0080] In a series of embodiments, a unified access control process allows network equipment to provide the access class, access ID, and admission control parameters. A repeater can determine the admission barring parameters applied through the access ID and access class in a single access attempt, execute a unified access control process (including an access barring check), and determine whether the access attempt is permitted or prohibited. If the access attempt is prohibited, it activates timer T390 corresponding to the access class. If T390 exceeds its time limit and timer T302 is not running (if the access class is 2, it is not necessary to consider whether timer T302 is running), the prohibition for that access class is lifted.

[0081] In a series of embodiments, after receiving the admission control parameters, the repeater may skip the unified access control process, or it may execute the unified access control process according to the admission control parameters, as described below.

[0082] (1) The repeater can skip the unified access control process. In a series of embodiments, in 701, the repeater receives an SIB1 transmitted by a network device, which includes admission control parameters, and in 702, the repeater skipping the first processing related to the admission control includes the repeater skipping the unified access control process.

[0083] In a series of embodiments, if the first condition is satisfied, the RRC layer of the repeater skips the unified access control process, and the first condition is met. When performing the RRC connection establishment process, and when requesting RRC connection establishment, the upper layer provides one access level and one or more access ID(s), or When the RRC connection recovery process is being performed, and the recovery of the RRC connection is triggered in response to an NG-RAN call, or When performing the RRC connection recovery process, and the recovery of the RRC connection is triggered by the upper layer, and the upper layer provides one access level and one or more access ID(s), This includes cases where an RRC connection recovery process is performed, and where the recovery of said RRC connection is excited by RNA renewal.

[0084] In a series of embodiments, when performing the RRC connection recovery process, and when the RRC connection recovery is triggered in response to an NG-RAN call, skipping the first process relating to admission control includes, as selectable, the lower layer (e.g., the RRC layer) of the repeater skipping the unified access control process, and further includes the RRC layer of the repeater selecting 0 as the access class.

[0085] In a series of embodiments, when an RRC connection recovery process is performed, and the recovery of the RRC connection is excited by RNA renewal, the unified access control process may include, and may be optional, the RRC layer of the repeater skipping the unified access control process, and may further include the ability of the RRC layer of the repeater to set the recovery establishment cause to an emergency situation when the RRC layer of the repeater does not determine the access level and / or performs an emergency task.

[0086] In a series of embodiments, the establishment cause must be included in the RRC connection establishment / recovery request, and although the lower layer of the repeater (e.g., the RRC layer) skips access control checks, in order to obtain the RRC establishment cause, the lower layer of the repeater (e.g., the RRC layer) needs to determine the access class and access ID(s) for each access attempt, and therefore determines the RRC establishment cause corresponding to the access class. Alternatively, the upper layer of the repeater (e.g., the NAS layer) does not provide the access class and access ID to the lower layer (e.g., the RRC layer), but provides the RRC establishment cause, and since the upper layer has already provided the RRC establishment cause, the establishment cause can be determined without determining the access class.

[0087] In a series of embodiments, in order to ensure access prohibition checks of access common sense determined by the lower layer under a 5GMM connection mode with an RRC deactivated state or RRC deactivation instruction, the upper layer of the repeater (e.g., the NAS layer) provides the lower layer (e.g., the RRC layer) with an access ID to be used for determined access attempts.

[0088] (2) The repeater can execute the unified access control process according to the admission control parameters. In a series of embodiments, admission control parameters can be associated with a repeater-specific (dedicated) access class and / or a repeater-specific access ID.

[0089] For example, multiple access levels can be defined in advance, such as standardized definitions AC0 to AC30 and provider definitions AC31 to AC63. Furthermore, repeater-specific access levels AC, such as AC64 and AC65, can be defined, or existing ACs can be changed to repeater-specific ones, such as AC31 and AC63. In addition, at least one of the 4 to 10 reserved in the access ID can be changed to a repeater-specific access ID. In 702, the repeater performing the second processing relating to admission control includes the repeater performing a unified access control process based on the repeater-specific access levels and / or access IDs, for example, the repeater determining the repeater-specific access levels and / or access IDs, the admission control parameters including a ban time and / or a ban factor, the ban time and / or ban factor being applied to the repeater-specific access levels and / or access IDs, and the repeater performing a unified access control process according to the admission control parameters associated with the repeater-specific access levels and / or access IDs.

[0090] In a series of embodiments, the admission control parameters may be relay-specific admission control parameters and include relay-specific prohibition factors and / or relay-specific prohibition times or relay-specific ratios / factors configured for access class and / or access ID, for example, the relay-specific prohibition factors and / or prohibition times are obtained after calculating (+×MOD, etc.) the prohibition factors and / or prohibition times of terminal equipment in the admission control parameters and the relay-specific ratios / factors. In 702, the relay performing a second process relating to admission control includes the relay performing a unified access control process using the relay-specific admission control parameters, for example, the relay determining the access class and / or access ID and the relay performing a unified access control process according to the relay-specific admission control parameters associated with the access class and / or access ID.

[0091] In a series of embodiments, for a repeater to perform a unified access control process according to admission control parameters (either admission control parameters associated with a repeater-specific access class and / or a repeater-specific access ID, or repeater-specific admission control parameters associated with an access class and / or access ID), the repeater obtains a random number uniformly distributed within the range [0,1) and if this random number is smaller than the value indicated by the prohibition factor obtained according to the admission control parameters, the repeater determines that the access attempt is permitted; otherwise, the repeater recognizes that the access attempt is prohibited. If the access attempt is prohibited, the repeater obtains a random number uniformly distributed within the range [0,1) and activates the timer T390 for this access class, the timer value is calculated using the prohibition time obtained according to the admission control parameters, and the formula is T390 = (0.7 + 0.6 × random number) × prohibition time. If timer T390 exceeds the time limit and timer T302 is not running (if the access level is 2, it is not necessary to consider whether timer T302 is running or not), the restriction on that access level is lifted.

[0092] It should be noted that the attached drawing 7 is merely a schematic description of the embodiment of the present invention, and the present invention is not limited thereto. For example, the order in which each operation is performed can be adjusted as appropriate, and furthermore, a series of other operations can be added or some operations can be deleted. Those skilled in the art can make appropriate modifications to the description in attached drawing 7, in accordance with the above content.

[0093] According to the above embodiment, the first information contained in the first message relating to repeater admission control is ignored, and / or the first processing relating to admission control is skipped, and / or the second processing relating to admission control is executed, so that the repeater is not subject to the control of the existing admission control mechanism, thereby mitigating network congestion and reducing allocation costs.

[0094] Example of the second aspect In this embodiment, an admission restriction method is provided, which will be described starting with network equipment.

[0095] Figure 8 is a schematic diagram of one admission restriction method in the embodiment of the present invention, and as shown in Figure 8, the method includes, 801, the network device sends a first message relating to admission control to a repeater, the first message containing first information which is a specific value, or the first message does not contain first information.

[0096] In a series of embodiments, the first message includes a RAR or MSGB, and the first information includes backoff instruction-related information.

[0097] In a series of embodiments, the RAR or MSGB either does not contain backoff instruction-related information, or it contains backoff instruction-related information, and the value indicated by the backoff is 0.

[0098] In a series of embodiments, the first message includes an RRC rejection message or an RRC release message, and the first information includes a waiting time.

[0099] In the series of embodiments, the RRC rejection message or RRC release message either does not include a waiting time, or it includes a waiting time, and the value of the waiting time is 0.

[0100] In a series of embodiments, the first message includes SIB1, and the first information includes admission control parameters.

[0101] In a series of embodiments, the SIB1 includes admission control parameters.

[0102] In a series of embodiments, the admission control parameter is a repeater-specific admission control parameter. The repeater-specific admission control parameter includes a repeater-specific prohibition factor and / or a repeater-specific prohibition time, or a repeater-specific ratio / factor.

[0103] In a series of embodiments, the admission control parameters are associated with an access class and an access ID, where the access class is a repeater-specific access class and the access ID is a repeater-specific access ID.

[0104] In the series of embodiments, the embodiments of the first message and the first information can be found by referring to (i) to (iv) in the first embodiment, and therefore will not be described in detail again here.

[0105] According to the above embodiment, since the repeater is not subject to the control of the existing admission control mechanism, network congestion can be alleviated and allocation costs can be reduced.

[0106] Figure 9A is a schematic diagram of one admission restriction method in the present embodiment, and as shown in Figure 9A, the method includes, 901, the network device does not send a first message relating to admission control to the repeater.

[0107] In a series of embodiments, in radio resource control (RRC) denial and RRC release, the first message includes an RRC denial message and / or an RRC release message, and the network device does not send an RRC denial message to the repeater, or does not send an RRC release message, meaning the repeater does not receive the first message (RRC denial message and / or RRC release message) relating to admission control sent by the network device.

[0108] In a series of embodiments, regarding the radio resource control (RRC) denial mechanism, prior to 901, the method further includes (not shown) the network device receiving a second message transmitted by the repeater, the second message including an RRC establishment request and / or an RRC recovery request, in other words, the network device does not deny the repeater's RRC establishment request and / or the repeater's RRC recovery request.

[0109] In a series of embodiments, the method may optionally further include the network device sending a third message to a repeater (not shown), the third message including an RRC establishment message and / or an RRC recovery message, which can be specifically described in the existing technology and will not be described further here.

[0110] In this series of embodiments, regarding the RRC release mechanism, the network device does not release the RRC connection to the repeater and therefore does not send an RRC release message to the repeater.

[0111] Figure 9B is a schematic diagram of one admission restriction method in the present embodiment, and as shown in Figure 9B, the method includes, 901' includes the fact that the repeater does not receive the first message regarding admission control transmitted by the network device.

[0112] In a series of embodiments, with respect to the radio resource control (RRC) denial mechanism, prior to 901, the method further includes (not shown) the repeater sending a second message to a network device, the second message may include an RRC establishment request and / or an RRC recovery request.

[0113] In a series of embodiments, the method may optionally further include receiving a third message transmitted by a network device, which may include an RRC establishment message and / or an RRC recovery message, the specifics of which can be found in existing technology and will not be described in further detail here.

[0114] In this series of embodiments, regarding the RRC release mechanism, the network device does not release the RRC connection to the repeater and therefore does not send an RRC release message to the repeater.

[0115] Therefore, since the repeater does not receive RRC rejection messages and / or RRC release messages and is not subject to the control of the existing admission control mechanism, network congestion can be alleviated and allocation costs can be reduced.

[0116] Figure 10 is a schematic diagram of one admission restriction method in the present embodiment, and as shown in Figure 10, the method includes, 1001. The network device receives the second message transmitted by the repeater, 1002, the network device processes the request for the second message at a high priority level.

[0117] In a series of embodiments, the radio resource control (RRC) denial admission control mechanism includes an RRC establishment request and / or an RRC recovery request in the second message, and in 1002, the processing of requests relating to the RRC establishment request and / or RRC recovery request at a high priority level by the network equipment includes processing access attempts of the repeater at a high priority level.

[0118] In a series of embodiments, the method further includes (not shown) that the network device sends a first message to the repeater if a second condition is met, and the first message may include an RRC denial message. The second condition includes an extreme network load that may threaten the stability of the network device, meaning that only under extreme network load conditions that may threaten the stability of the network device, the repeater's access attempt (request for the second message) is denied, and an RRC denial message is sent to the repeater regarding the repeater's access attempt.

[0119] In the series of embodiments, in 1001, if the repeater attempts to establish a new connection while in an RRC idle state, or attempts to recover a connection from an RRC deactivated state, it sends the second message. For example, if the repeater attempts to establish a new connection while in an RRC idle state, it sends an RRC establishment request message, or if it attempts to recover a connection from an RRC deactivated state, it sends an RRC recovery request message.

[0120] In this way, network devices process requests for the second message with a high priority level, reducing the likelihood of relay access attempts being denied, thus alleviating network congestion and lowering allocation costs.
