Description

Technical Field

[0001] This invention relates to the field of communication technology, and in particular to an access control method, system, device, medium, chip, terminal and base station. Background Technology

[0002] In 4G / 5G communication (4G and 5G are both communication technologies), to support UE (user equipment) (terminal) access to the network, the PRACH (Physical Random Access Channel) channel is designed in the 3GPP (3rd Generation Partnership Project) protocol of the NR (New Radio) technology standard. The network / base station side indicates the access resources of the PRACH channel in the SIB (System Information Block). The UE can randomly select one of these access resources to send a preamble sequence. The network side obtains the access UE information by receiving the preamble sequence information.

[0003] However, if the network side determines preamble resources from all available resources, the base station needs to blindly check all preamble resources to determine if a user has requested access, which significantly increases energy consumption and complexity. Furthermore, according to GSMA (Global System for Mobile Communications Association) analysis, energy costs account for a high percentage of operator expenses; therefore, energy conservation and consumption reduction are extremely important for operators.

When the UE needs to request access resources, it sends a specific preamble resource request.

This eliminates the need for blind detection of all resources, greatly reducing the demodulation overhead and energy consumption of the base station, thereby achieving effective energy saving. At the same time, it effectively simplifies the entire resource request access process and improves the efficiency and reliability of access control. Attached Figure Description

[0104] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0105] Example 1

[0106] The access control method in this embodiment is applied on the base station side.

[0107] like Figure 1 As shown, the access control method in this embodiment includes:

[0108] S101. Determine preset indication information based on the system information block (SIB);

[0109] Among them, the preset indication information is used to indicate that the carrier in the cell does not support the terminal's initial access;

[0110] In one feasible approach, the preset indication information is determined when the preamble initial root sequence information in the System Information Block (SIB) is not configured; the preset parameter information is configured in the SIB using a pre-configuration method. For example, PRACH only detects sequences with a PRACH preamble index of 0 or preset specific sequences.

[0111] That is, by modifying the protocol standard accordingly, the preamble initial root sequence information is not configured. At this time, the base station indicates to the terminal UE that the carrier does not accept the preamble or does not support the UE to perform initial access, so that the base station is in a low power consumption state, thereby reducing the energy consumption output of the base station and achieving the effect of improving energy saving.

[0112] S102, Receive a resource request request containing a preset preamble sequence sent by the current terminal;

[0113] The preset preamble sequence is used to represent the access resource request information sent by the current terminal. Specifically, the access resource request information can be the preamble resource request information.

[0114] The base station receives a specific preamble resource request from the receiving terminal. It only responds to preamble sequences that meet certain conditions (such as preamble0 or other specific preamble sequences). Otherwise, it does not perform an access response operation, which greatly simplifies the entire resource request access process.

[0115] In this embodiment, the base station indicates to the UE that the carrier does not accept preamble or does not support the UE's initial access by not configuring preamble root sequence information or configuring a specific preamble sequence in the SIB. For example, the PRACH only detects the sequence with PRACH preamble index of 0 or a preset specific sequence. When the UE needs to request access resources, it sends a specific preamble resource request request. The base station receives and responds to the resource request request, realizing that it only accepts the specific preamble sequence. It no longer needs to perform blind detection on all resources, which greatly reduces the demodulation overhead and energy consumption of the base station, thereby achieving effective energy saving. At the same time, it effectively simplifies the entire resource request access process and improves the efficiency and reliability of access control.

[0116] Example 2

[0117] The access control method in this embodiment is a further improvement on embodiment 1, specifically:

[0118] In a feasible solution, such as Figure 2 As shown, after step S102, the following steps are also included:

[0119] S103. Respond to resource request requests using preset response rules.

[0120] In a feasible solution, such as Figure 3 As shown, step S103 specifically includes:

[0121] S1031. Based on the resource request, modify the downlink control information (DCI) of the random access response (RAR) scheduling so that the downlink control information (DCI) contains content indicating whether to respond to the request.

[0122] or,

[0123] Based on the resource request, modify the random access response RAR message so that it includes information indicating whether the request is being responded to.

[0124] In a feasible solution, such as Figure 4 As shown, step S103 specifically includes:

[0125] S1032. Based on the resource request, indicate the initial root sequence information corresponding to the preamble sequence in the downlink control information (DCI) of the random access response (RAR) scheduling and / or in the random access response (RAR) message.

[0126] Specifically, the response can be made by modifying the content of the downlink control information (DCI) of the random access response (RAR) scheduling, for example, by directly modifying the previous information in the DCI to 1 bit, or by adding 1 bit to the content of the DCI.

[0127] The response can be made by modifying the Random Access Response (RAR) message, for example, by directly modifying the previous information in the RAR message to 1 bit, or by adding 1 bit to the RAR message.

[0128] Of course, other modification methods can also be used, and the specific method can be redetermined or adjusted according to actual needs.

[0129] If the modified Downlink Control Information (DCI) or Random Access Response (RAR) message contains content indicating a determination to respond, then subsequent response operations will continue to be executed; if it contains content indicating a determination not to respond, then subsequent response operations will not be executed.

[0130] Alternatively, the resource request request of the current terminal can be responded to by directly indicating the initial root sequence information corresponding to the preamble sequence in the downlink control information (DCI) of the random access response (RAR) scheduling, and / or in the random access response (RAR) message.

[0131] Alternatively, the modified Downlink Control Information (DCI) and Random Access Response (RAR) message methods described above can be combined with the methods of scheduling the DCI in the RAR message and / or directly indicating the initial root sequence information corresponding to the preamble sequence in the RAR message. These two approaches can be used to ensure the effectiveness of access control. The specific method used can be determined or adjusted according to the actual scenario requirements.

[0132] It should be noted that all parameter information in this embodiment can be reset according to the actual situation.

[0133] In one feasible scheme, the carrier corresponds to the Non-Anchor carrier, and a preamble sequence is used to indicate to the Non-Anchor carrier that the current terminal needs to access the Non-Anchor carrier, and / or to request access resources from the Non-Anchor carrier.

[0134] In a feasible solution, such as Figure 5 As shown, the carrier corresponds to the anchor carrier, and the access control method also includes:

[0135] S10301. Add a Non-Anchor carrier indication to the System Information Block (SIB) of the Anchor carrier;

[0136] Step S103 specifically includes:

[0137] S1033. Based on the resource request, modify the downlink control information (DCI) of the random access response (RAR) scheduling so that the downlink control information (DCI) contains PRACH resource information representing the corresponding Anchor carrier or other non-Anchor carrier.

[0138] or,

[0139] Based on the resource request, modify the Random Access Response (RAR) message so that it includes PRACH resource information representing the corresponding Anchor carrier or other designated Non-Anchor carrier.

[0140] Specifically, the steps for indicating the corresponding PRACH resource information in the Anchor carrier include:

[0141] Instructs the configuration of new PRACH resource information in the Anchor carrier;

[0142] or,

[0143] The steps for instructing other settings of the corresponding PRACH resource information in the Non-Anchor carrier include:

[0144] Configure other settings for resource indication information corresponding to Non-Anchor carriers, and use the resource indication information as the corresponding PRACH resource information.

[0145] The resource indication information includes, but is not limited to, the carrier type, carrier index, and PRACH information of the Non-Anchor carrier.

[0146] Specifically, a Non-Anchor Carrier Indicator is added to the SIB of the Anchor Carrier, and a sequence with an Anchor Carrier PRACH preamble index of 0 or a preset specific sequence is used to indicate to the Anchor Carrier that resources need to be added for PRACH.

[0147] (1) The base station can use the DCI scheduled by Random Access Response (RAR) to respond, and the DCI content is modified as follows:

[0148] 0 indicates that the method of adding PRACH resources is used on this carrier (Anchor carrier);

[0149] Instructs the Anchor carrier to configure new PRACH resource information;

[0150] 1 indicates that other non-anchor carriers are accessing the network; subsequent bits include, but are not limited to, the following:

[0151] Indicates FDD / TDD carrier, carrier index, and PRACH resource information;

[0152] The PRACH resource information can be a direct indication; or multiple sets of resource information can be configured in the SIB, where the index information is used to indicate the selection of one set from the multiple sets of resource information in the SIB.

[0153] (2) Use a RAR message to respond, and modify the content of the RAR message as follows:

[0154] 0 indicates that the method of adding PRACH resources is used on this carrier (Anchor carrier);

[0155] Instructs the Anchor carrier to configure new PRACH resource information;

[0156] 1 indicates that other non-anchor carriers are accessing the network; subsequent bits include, but are not limited to, the following:

[0157] Indicates FDD / TDD carrier, carrier index, and PRACH resource information;

[0158] The PRACH resource information can be a direct indication; or multiple sets of resource information can be configured in the SIB, where the index information is used to indicate the selection of one set from the multiple sets of resource information in the SIB.

[0159] The two response methods mentioned above can be selected or combined to ultimately determine the execution of the access response operation. The specific method can be determined or adjusted according to the actual needs of the scenario.

[0160] It should be noted that all parameter information in this embodiment can be reset according to the actual situation.

[0161] In a feasible solution, such as Figure 6 As shown, the procedure before step S102 also includes:

[0162] S10201. The correspondence between each Non-Anchor carrier and the preset preamble sequence is indicated in advance in the System Information Block (SIB) of the Anchor carrier.

[0163] Each Non-Anchor carrier corresponds to a pre-defined preamble sequence, and they are all different from each other;

[0164] The steps following step S102 and before step S103 include:

[0165] S10302. Match the Non-Anchor carrier corresponding to the resource request and send the resource request on the Anchor carrier using the corresponding preset preamble sequence.

[0166] Specifically, the SIB of the Anchor carrier indicates the correspondence between multiple other Non-Anchor carriers and each specific preamble sequence. The UE, based on the best-measured Non-Anchor carrier, sends a preamble resource access request on the Anchor carrier using the corresponding preamble sequence. At this time, the UE automatically matches the Non-Anchor carrier corresponding to the preamble sequence sent by the terminal and responds to the access request. For example, Anchor carrier A corresponds to preamble1, Non-Anchor carrier B corresponds to preamble2, Non-Anchor carrier C corresponds to preamble3, Non-Anchor carrier D corresponds to preamble3, and so on. If the UE receives a resource request containing preamble3 from the terminal, it automatically matches the Non-Anchor carrier C corresponding to the terminal.

[0167] The response process or implementation principle of Anchor carrier A is the same as the access control principle when the carrier corresponds to the Anchor carrier mentioned above, so it will not be described again here.

[0168] In this embodiment, the base station indicates to the UE that the carrier does not accept preamble or does not support the UE's initial access by not configuring preamble root sequence information or configuring a specific preamble sequence in the SIB. For example, the PRACH only detects the sequence with PRACH preamble index of 0 or a preset specific sequence. When the UE needs to request access resources, it sends a specific preamble resource request request. The base station receives and responds to the resource request request, realizing that it only accepts the specific preamble sequence. It no longer needs to perform blind detection on all resources, which greatly reduces the demodulation overhead and energy consumption of the base station, thereby achieving effective energy saving. At the same time, it effectively simplifies the entire resource request access process and improves the efficiency and reliability of access control.

[0169] Example 3

[0170] The access control method in this embodiment is applied on the terminal side.

[0171] like Figure 7 As shown, the access control method in this embodiment includes:

[0172] S201. Obtain the preset indication information in the System Information Block (SIB) on the base station side;

[0173] Among them, the preset indication information is used to indicate that the carrier in the cell does not support the terminal's initial access;

[0174] In one feasible approach, the preset indication information is determined when the preamble initial root sequence information in the System Information Block (SIB) is not configured; the preset parameter information is configured in the SIB using a pre-configuration method. For example, PRACH only detects sequences with a PRACH preamble index of 0 or preset specific sequences.

[0175] That is, by modifying the protocol standard accordingly, the preamble initial root sequence information is not configured. At this time, the base station indicates to the terminal UE that the carrier does not accept the preamble or does not support the UE to perform initial access, so that the base station is in a low power consumption state, thereby reducing the energy consumption output of the base station and achieving the effect of improving energy saving.

[0176] S202, Send a resource request containing a preset preamble sequence;

[0177] The preset preamble sequence is used to represent the access resource request information sent by the current terminal to the base station; specifically, the access resource request information can be preamble resource request information.

[0178] The implementation principle of the access control method on the terminal side in this embodiment corresponds to the access control method on the base station side in Embodiment 1. For details, please refer to Embodiment 1, which will not be repeated here.

[0179] In this embodiment, based on the base station's determination that the base station's carrier does not accept preamble or does not support initial access by configuring a specific preamble sequence in the SIB (System Instructions for Access), the UE determines that the base station's carrier does not accept preamble or supports initial access. When the UE needs to request access resources, it sends a specific preamble resource request. The UE accesses the system after receiving a response from the base station confirming that a user has requested access resources. This achieves access based solely on a specific preamble sequence, greatly reducing the demodulation overhead and energy consumption on the base station side, thus achieving effective energy saving. At the same time, it effectively simplifies the entire resource request access process and improves the efficiency and reliability of access control.

[0180] Example 4

[0181] The access control method in this embodiment is a further improvement on embodiment 3, specifically:

[0182] In one feasible scheme, the carrier corresponds to the Non-Anchor carrier, and a preamble sequence is used to indicate to the Non-Anchor carrier that the current terminal needs to access the Non-Anchor carrier, and / or to request access resources from the Non-Anchor carrier.

[0183] In one feasible scheme, the carrier corresponds to the anchor carrier, the current terminal needs the base station to add PRACH resources, and / or the current terminal requests PRACH resources from the base station.

[0184] It should be noted that the implementation principle of the access control method on the terminal side in this embodiment corresponds to the access control method on the base station side in Embodiment 2. For details, please refer to Embodiment 2, which will not be repeated here.

[0185] In this embodiment, based on the base station's determination that the base station's carrier does not accept preamble or does not support initial access by configuring a specific preamble sequence in the SIB (System Instructions for Access), the UE determines that the base station's carrier does not accept preamble or supports initial access. When the UE needs to request access resources, it sends a specific preamble resource request. The UE accesses the system after receiving a response from the base station confirming that a user has requested access resources. This achieves access based solely on a specific preamble sequence, greatly reducing the demodulation overhead and energy consumption on the base station side, thus achieving effective energy saving. At the same time, it effectively simplifies the entire resource request access process and improves the efficiency and reliability of access control.

[0186] Example 5

[0188] like Figure 8 As shown, the access control system in this embodiment includes:

[0189] Preset indication information determination module 1 is used to determine preset indication information based on system information block SIB;

[0190] Among them, the preset indication information is used to indicate that the carrier in the cell does not support the terminal's initial access;

[0191] In one feasible approach, the preset indication information is determined when the preamble initial root sequence information in the System Information Block (SIB) is not configured; the preset parameter information is configured in the SIB using a pre-configuration method. For example, PRACH only detects sequences with a PRACH preamble index of 0 or preset specific sequences.

[0192] That is, by modifying the protocol standard accordingly, the preamble initial root sequence information is not configured. At this time, the base station indicates to the terminal UE that the carrier does not accept the preamble or does not support the UE to perform initial access, so that the base station is in a low power consumption state, thereby reducing the energy consumption output of the base station and achieving the effect of improving energy saving.

[0193] Resource request receiving module 2 is used to receive a resource request containing a preset preamble sequence sent by the current terminal;

[0194] The preset preamble sequence is used to represent the access resource request information sent by the current terminal. Specifically, the access resource request information can be preamble resource request information.

[0195] The base station receives a specific preamble resource request from the receiving terminal. It only responds to preamble sequences that meet certain conditions (such as preamble0 or other specific preamble sequences). Otherwise, it does not perform an access response operation, which greatly simplifies the entire resource request access process.

[0196] It should be noted that the implementation principle of the access control system in this embodiment is the same as that of the access control method in Embodiment 1, so it will not be described again here.

[0197] In this embodiment, the base station indicates to the UE that the carrier does not accept preamble or does not support the UE's initial access by not configuring preamble root sequence information or configuring a specific preamble sequence in the SIB. For example, the PRACH only detects the sequence with PRACH preamble index of 0 or a preset specific sequence. When the UE needs to request access resources, it sends a specific preamble resource request request. The base station receives and responds to the resource request request, realizing that it only accepts the specific preamble sequence. It no longer needs to perform blind detection on all resources, which greatly reduces the demodulation overhead and energy consumption of the base station, thereby achieving effective energy saving. At the same time, it effectively simplifies the entire resource request access process and improves the efficiency and reliability of access control.

[0198] Example 6

[0199] like Figure 9 As shown, the access control system in this embodiment is a further limitation of embodiment 5, specifically:

[0200] In one feasible solution, the access control system also includes:

[0201] Request-response module 3 is used to respond to resource request requests using preset response rules.

[0202] Specifically, in one feasible scheme, the request response module 3 is used to modify the downlink control information (DCI) of the random access response (RAR) scheduling according to the resource request request, so that the downlink control information (DCI) contains content indicating whether to respond to the request.

[0203] or,

[0204] Based on the resource request, modify the random access response RAR message so that it includes information indicating whether the request is being responded to.

[0205] In one feasible scheme, the request response module 3 is used to indicate the initial root sequence information corresponding to the preamble sequence in the downlink control information (DCI) of the random access response (RAR) scheduling, and / or in the random access response (RAR) message, based on the resource request request.

[0206] In one feasible scheme, the carrier corresponds to the Non-Anchor carrier, and a preamble sequence is used to indicate to the Non-Anchor carrier that the current terminal needs to access the Non-Anchor carrier, and / or to request access resources from the Non-Anchor carrier.

[0207] In one feasible solution, the carrier corresponds to the anchor carrier, and the access control system also includes:

[0208] An indicator addition module is provided to add a Non-Anchor carrier indicator to the System Information Block (SIB) of the Anchor carrier.

[0209] Request response module 3 is used to modify the downlink control information (DCI) of the random access response (RAR) scheduling based on the resource request request, so that the downlink control information (DCI) contains the PRACH resource information corresponding to the Anchor carrier or other non-Anchor carrier.

[0210] or,

[0211] Based on the resource request, modify the Random Access Response (RAR) message so that it includes PRACH resource information representing the corresponding Anchor carrier or other designated Non-Anchor carrier.

[0212] In one feasible solution, the access control system also includes:

[0213] Resource information indication module 4 is used to indicate the configuration of new PRACH resource information in the Anchor carrier;

[0214] Alternatively, configure other settings for resource indication information corresponding to the Non-Anchor carrier, and use the resource indication information as the corresponding PRACH resource information.

[0215] The resource indication information includes, but is not limited to, the carrier type, carrier index, and PRACH information of the Non-Anchor carrier.

[0216] In one feasible solution, the access control system also includes:

[0217] The correspondence indication module 5 is used to indicate the correspondence between each Non-Anchor carrier and a preset preamble sequence in the System Information Block (SIB) of the Anchor carrier in advance;

[0218] Each Non-Anchor carrier corresponds to a pre-defined preamble sequence, and they are all different from each other;

[0219] The carrier matching module is used to match the non-anchor carrier corresponding to the resource request and send the resource request on the anchor carrier using the corresponding preset preamble sequence.

[0220] It should be noted that the implementation principle of the access control system in this embodiment is the same as that of the access control method in embodiment 2, so it will not be described again here.

[0221] In this embodiment, the base station indicates to the UE that the carrier does not accept preamble or does not support the UE's initial access by not configuring preamble root sequence information or configuring a specific preamble sequence in the SIB. For example, the PRACH only detects the sequence with PRACH preamble index of 0 or a preset specific sequence. When the UE needs to request access resources, it sends a specific preamble resource request request. The base station receives and responds to the resource request request, realizing that it only accepts the specific preamble sequence. It no longer needs to perform blind detection on all resources, which greatly reduces the demodulation overhead and energy consumption of the base station, thereby achieving effective energy saving. At the same time, it effectively simplifies the entire resource request access process and improves the efficiency and reliability of access control.

[0222] Example 7

[0223] The base station in this embodiment includes the access control system in embodiment 5 or 6.

[0224] Base stations include various types of base stations, such as macro base stations, micro base stations, pole base stations, repeaters, etc.

[0225] In this embodiment, the base station integrates the aforementioned access control system to accept only specific preamble sequences, eliminating the need for blind detection of all resources. This significantly reduces demodulation overhead and energy consumption, thereby achieving effective energy saving.

[0226] Example 8

[0227] The access control system in this embodiment is applied on the terminal side.

[0228] like Figure 10 As shown, the access control system in this embodiment includes:

[0229] The preset indication information acquisition module 6 is used to acquire preset indication information in the system information block (SIB) on the base station side;

[0230] Among them, the preset indication information is used to indicate that the carrier in the cell does not support the terminal's initial access;

[0231] In one feasible approach, the preset indication information is determined when the preamble initial root sequence information in the System Information Block (SIB) is not configured; the preset parameter information is configured in the SIB using a pre-configuration method. For example, PRACH only detects sequences with a PRACH preamble index of 0 or preset specific sequences.

[0232] That is, by modifying the protocol standard accordingly, the preamble initial root sequence information is not configured. At this time, the base station indicates to the terminal UE that the carrier does not accept the preamble or does not support the UE to perform initial access, so that the base station is in a low power consumption state, thereby reducing the energy consumption output of the base station and achieving the effect of improving energy saving.

[0233] Resource request sending module 7 is used to send resource request requests containing a preset preamble sequence;

[0234] The preset preamble sequence is used to represent the access resource request information sent by the current terminal to the base station. Specifically, the access resource request information can be preamble resource request information.

[0235] It should be noted that the implementation principle of the access control system in this embodiment is the same as that of the access control method in embodiment 3, so it will not be described again here.

[0236] In this embodiment, based on the base station's determination that the base station's carrier does not accept preamble or does not support initial access by configuring a specific preamble sequence in the SIB (System Instructions for Access), the UE determines that the base station's carrier does not accept preamble or supports initial access. When the UE needs to request access resources, it sends a specific preamble resource request. The UE accesses the system after receiving a response from the base station confirming that a user has requested access resources. This achieves access based solely on a specific preamble sequence, greatly reducing the demodulation overhead and energy consumption on the base station side, thus achieving effective energy saving. At the same time, it effectively simplifies the entire resource request access process and improves the efficiency and reliability of access control.

[0237] Example 9

[0238] The access control system in this embodiment is a further limitation of embodiment 8, specifically:

[0239] In one feasible scheme, the carrier corresponds to the Non-Anchor carrier, and a preamble sequence is used to indicate to the Non-Anchor carrier that the current terminal needs to access the Non-Anchor carrier, and / or to request access resources from the Non-Anchor carrier.

[0240] In one feasible scheme, the carrier corresponds to the anchor carrier, the current terminal needs the base station to add PRACH resources, and / or the current terminal requests PRACH resources from the base station.

[0241] It should be noted that the implementation principle of the access control system in this embodiment is the same as that of the access control method in embodiment 4, so it will not be described again here.

[0242] In this embodiment, based on the base station's determination that the base station's carrier does not accept preamble or does not support initial access by configuring a specific preamble sequence in the SIB (System Instructions for Access), the UE determines that the base station's carrier does not accept preamble or supports initial access. When the UE needs to request access resources, it sends a specific preamble resource request. The UE accesses the system after receiving a response from the base station confirming that a user has requested access resources. This achieves access based solely on a specific preamble sequence, greatly reducing the demodulation overhead and energy consumption on the base station side, thus achieving effective energy saving. At the same time, it effectively simplifies the entire resource request access process and improves the efficiency and reliability of access control.

[0243] Example 10

[0244] The terminal in this embodiment includes the access control system described in embodiment 8 or 9.

[0245] In this embodiment, the terminal side integrates the aforementioned access control system. When it is determined that the carrier on the base station side does not accept preamble or does not support the UE for initial access, it sends a specific preamble resource request. When it receives a response from the base station side after determining that a user has requested access resources, it accesses the device. This enables access based only on a specific preamble sequence, which greatly reduces the demodulation overhead and energy consumption on the base station side, thereby achieving effective energy saving.
