[0002] This disclosure claims priority to Chinese Patent Application No. 202411028775.X, filed on July 30, 2024, entitled "Access Method, Apparatus and Computer-Readable Storage Medium", the entire contents of which are incorporated herein by reference. Technical Field

[0003] This disclosure relates to the field of communication technology, and in particular to an access method, apparatus and computer-readable storage medium. Background Technology

[0004] Currently, in 5G (5th Generation Mobile Communication Technology) systems, when a UE (User Equipment) accesses a network cell, it needs to first read the SSB (SS (Synchronization Signal) / PBCH (Physical Broadcast Channel) block) and then read SIB1 to obtain access information. Based on this access information, it then initiates an access procedure to the network cell.

[0005] The SSB includes a synchronization signal and the PBCH. The UE achieves downlink synchronization with the network cell by reading the synchronization signal. The PBCH carries the MIB (Master Information Block), which includes cell prohibition status information and basic physical layer information of the network cell required for further receiving system information. The UE also obtains the parameters for SIB1 from the MIB. The MIB and SIB1 are periodically broadcast and repeatedly transmitted on the BCH (Broadcast Channel).

[0006] The design of 5G systems for acquiring system messages and access parameters results in the same access latency for all UEs. For the network side, the periodic broadcasting and repeated transmission of MIB and SIB1 occupy downlink resources, increasing network energy consumption and reducing downlink capacity. Therefore, a more efficient access resource acquisition and terminal access scheme is needed to achieve the goals of fast terminal access and network energy saving. Summary of the Invention

[0070] In this embodiment of the invention, the term "and / or" describes the relationship between associated objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. The character " / " generally indicates that the preceding and following associated objects have an "or" relationship.

[0071] In this disclosure, the term "multiple" refers to two or more, and other quantifiers are similar.

[0072] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this disclosure.

[0073] Currently, in 5G systems, when a UE accesses a network cell, it needs to first read the SSB and then read the SIB1 to obtain access information. The UE can then initiate an access procedure based on this access information. The SSB includes a synchronization signal and a PBCH. The UE achieves downlink synchronization with the network cell by reading the synchronization signal. The PBCH carries the MIB, which includes cell prohibition status information and basic physical layer information of the network cell required for further receiving system information. The parameters for obtaining SIB1 are also obtained from the MIB. The MIB and SIB1 are periodically broadcast and repeatedly transmitted on the BCH. The design of 5G systems for obtaining system messages and access parameters means that, for the UE, all UEs have the same access latency; for the network cell, the periodic broadcasting and repeated transmission of MIB and SIB1 consumes downlink resources, increases network energy consumption, and reduces downlink capacity.

[0074] The following will describe in detail an access method provided by an embodiment of this disclosure, with reference to specific implementation methods. Figure 1 is a flowchart of an access method provided by an embodiment of this disclosure. The method is applied to a UE, and as shown in Figure 1, the steps are as follows:

[0075] Step 101: Receive AP-RS sent by at least one AP.

[0076] In some embodiments, an Access Point (AP) periodically transmits a physical layer sequence, AP-RS (Access Point Reference Signaling). The transmission period and timing of the AP-RS are defined by a protocol. The AP can be a base station of a radio access network, a relay node, a transmitting terminal in a D2D (Device-to-Device) network, etc. In some embodiments, a UE can periodically receive AP-RS transmitted by at least one AP according to an agreement, and achieve time and frequency synchronization with the AP based on the timing and frequency of the AP-RS.

[0077] As an optional implementation, AP-RS includes AP-ID and necessary access configuration information.

[0078] (1) AP-ID includes one or more of PLMN (Public Land Mobile Network) identifier, base station identifier, and cell identifier;

[0079] (2) Necessary access configuration information includes one or more of the following: access denied indication information (bar), downlink common control channel spatial parameters (i.e., CORESET#0 configuration parameters), AP channel selection quality parameters, SI (System Information) support indication information, reading broadcast system message indication information, and access configuration parameter acquisition indication information based on default configuration.

[0080] Among them, the access prohibition indication information is used to indicate whether the AP allows the UE to access; the downlink common control channel space parameter is the CORESET#0 configuration parameter, which is used by the UE to determine the downlink common control channel space of the downlink common channel; the AP selection channel quality parameter is used by the UE to select the AP to access; the SI support indication information is used to indicate whether the AP supports sending SI and the type of SI that it supports sending; the read broadcast system message indication information is used to indicate that the UE obtains the access configuration parameters by reading the system messages sent by the AP in the broadcast manner; and the access configuration parameter acquisition based on default configuration indication information is used to indicate that the UE obtains the access configuration parameters based on the default configuration.

[0081] Figure 2 is a schematic diagram of an AP-RS provided in an embodiment of this disclosure. As shown in Figure 2, the two segments of the AP-RS are located at different frequency positions and may be the same or different in time position. In some embodiments, the first segment is used to carry the AP-ID; since the AP-ID is relatively long, it can be implemented through a multi-level sequence. In Figure 2, a 5-level sequence is used as an example, namely the 1st Stage Sequence to the 5th Stage Sequence; the second segment is used to carry necessary access configuration information; the AP can determine whether the second segment appears based on whether other information needs to be sent, and it can also be implemented through a multi-level sequence; Figure 2 also uses a 5-level sequence as an example, namely the 1st Stage Sequence to the 5th Stage Sequence.

[0082] Step 102: Determine the target AP based on the AP-RS sent by at least one AP.

[0083] In some embodiments, after receiving an AP-RS sent by at least one AP, the UE can determine a target AP among the at least one AP based on the AP-RS sent by the at least one AP. The target AP may be an AP selected by the UE for obtaining access configuration parameters.

[0084] As an optional implementation, determining the target AP includes one or more of the following:

[0085] (1) In at least one AP, the AP included in AP-RS whose channel quality parameters meet the channel quality threshold is determined as the target AP.

[0086] (2) In at least one AP, the AP whose access denial indication information is not included in the AP-RS, or whose access denial indication information included in the AP-RS indicates that access is allowed, is identified as the target AP.

[0087] Step 103: Obtain access configuration parameters based on the target AP-RS associated with the target AP.

[0088] In some embodiments, after receiving the target AP-RS sent by the target AP periodically as agreed, the UE can obtain access configuration parameters based on the target AP-RS.

[0089] Step 104: Access the network based on the access configuration parameters.

[0090] In some embodiments, after obtaining the access configuration parameters, the UE can access the network based on the access configuration parameters.

[0091] As an optional implementation, the UE can determine different methods for obtaining access configuration parameters based on the target AP-RS, according to its own different needs. The UE can then further obtain access configuration parameters based on the methods used to obtain these parameters, which include:

[0092] Step 1: Determine the method for obtaining access configuration parameters based on the target AP-RS associated with the target AP;

[0093] In some embodiments, the UE may determine the method of obtaining access configuration parameters based on the target AP-RS associated with the target AP.

[0094] As an optional implementation method, the access configuration parameters can be obtained in one or more of the following ways:

[0095] (1) Obtain access configuration parameters using the default method. The access configuration parameters include one or more of the following: downlink common control channel space of the downlink common channel, time domain resources for transmitting UE-RS, and frequency domain resources for transmitting UE-RS.

[0096] (2) Access configuration parameters are obtained through unicast or broadcast messages. These access configuration parameters include one or more of the following: downlink common control channel space of the downlink common channel, time-domain resources for transmitting UE-RS, frequency-domain resources for transmitting UE-RS, and other access configuration parameters. In some embodiments, other access configuration parameters may include UAC (Unified Access Control), physical layer uplink and downlink resource configurations, etc. It should be noted that broadcast in these embodiments may also include both broadcast and multicast.

[0097] In some embodiments, obtaining access configuration parameters via unicast or broadcast messages may further include obtaining access configuration parameters by the AP actively sending a unicast message; obtaining access configuration parameters by requesting the AP to send a unicast message; obtaining access configuration parameters by the AP actively sending a broadcast message; and obtaining access configuration parameters by requesting the AP to send a broadcast message.

[0098] As an optional implementation method, the method for obtaining access configuration parameters includes one or more of the following:

[0099] (1) Determine the method of obtaining access configuration parameters based on the indication information included in the target AP-RS.

[0100] (2) Determine the method of obtaining access configuration parameters based on the type or capability of the UE and / or the target AP.

[0101] (3) Determine the method of obtaining access configuration parameters based on the agreement.

[0102] In some embodiments, determining the method for obtaining access configuration parameters based on indication information included in the target AP-RS includes: if the target AP-RS includes indication information for obtaining access configuration parameters based on a default method, determining that the method for obtaining access configuration parameters is the default method. If the target AP-RS includes indication information for reading broadcast system messages and / or SI support indication information, determining that the method for obtaining access configuration parameters is through unicast and / or broadcast messages. In some embodiments, if the target AP-RS includes indication information for reading broadcast system messages, determining that the method for obtaining access configuration parameters is through the AP actively sending a broadcast message. If the target AP-RS includes indication information for reading broadcast system messages and SI support indication information, determining that the method for obtaining access configuration parameters is by requesting the AP to send a broadcast message. If the target AP-RS includes SI support indication information, determining that the method for obtaining access configuration parameters is by requesting the AP to send a unicast message or by requesting the AP to send a broadcast message.

[0103] In some embodiments, determining the method for obtaining access configuration parameters based on the type or capability of the UE and / or the target AP includes: determining the method for obtaining access configuration parameters as a default method based on the type or capability of the UE and / or the target AP; and determining the method for obtaining access configuration parameters as a unicast and / or broadcast method based on the type or capability of the UE and / or the target AP. In some embodiments, determining the method for obtaining access configuration parameters as a default method based on the type or capability of the UE and / or the target AP means that the UE and the AP cannot obtain access configuration parameters by sending system messages via broadcast or unicast messages due to the type or capability of one or both of the UE and the AP. Therefore, when the type or capability of the UE and the target AP restricts the acquisition of access configuration parameters by sending system messages via broadcast or unicast messages, the default method can be used to obtain access configuration parameters, thereby greatly simplifying the access process. The UE can directly extract the necessary information from the AP-RS without waiting for or requesting additional system messages, thereby quickly completing the access process and improving overall access efficiency. In some embodiments, when the access configuration parameters are determined to be obtained via unicast and / or broadcast based on the type or capability of the UE and / or the target AP, the UE can receive the minimum system message sent by the AP via unicast or broadcast messages and obtain the access configuration parameters from the minimum system message. This allows the UE to flexibly obtain the access configuration parameters according to its own needs, thereby quickly completing the access process and improving the overall access efficiency.

[0104] In some embodiments, the method for obtaining access configuration parameters is determined based on the protocol agreement, including: determining the method for obtaining access configuration parameters as the default method based on the protocol agreement.

[0105] Step 2: Obtain the access configuration parameters based on the method of obtaining access configuration parameters.

[0106] In some embodiments, after determining the method for obtaining access configuration parameters, the UE can further obtain access configuration parameters based on the method for obtaining access configuration parameters.

[0107] As an optional implementation, the acquisition of the access configuration parameters provided in this disclosure embodiment can refer to one or more of the following methods:

[0108] Method 1 (obtain access configuration parameters via default method): Based on the target AP-RS, determine one or more of the following: downlink common control channel space for receiving downlink common channels, time domain resources for transmitting UE-RS, and frequency domain resources for transmitting UE-RS.

[0109] In some embodiments, the UE can determine one or more of the following based on the target AP-RS: the downlink common control channel space for receiving the downlink common channel, the time-domain resources for transmitting the UE-RS, and the frequency-domain resources for transmitting the UE-RS. The downlink common control channel space for receiving the downlink common channel, the time-domain resources for transmitting the UE-RS, and the frequency-domain resources for transmitting the UE-RS can be used as access configuration parameters.

[0110] Method 2 (obtaining access configuration parameters via unicast or broadcast messages): Send an access request to the target AP via UE-RS or system messages, and receive access configuration parameters via unicast or broadcast messages.

[0111] In some embodiments, for obtaining access configuration parameters via unicast or broadcast messages, the UE can send an access request to the target AP via UE-RS or system messages, and receive access configuration parameters via unicast or broadcast messages. Further, the processing procedures for obtaining access configuration parameters via unicast messages or via broadcast messages are as follows.

[0112] (1) Obtaining access configuration parameters via unicast messages. When the access configuration parameters are obtained via unicast, the UE's process for obtaining the access configuration parameters based on this method is as follows:

[0113] Step 1: Obtain downlink resource allocation based on the target AP-RS. Downlink resource allocation includes one or more of the following: downlink common control channel space of the downlink common channel, time-domain resources for transmitting UE-RS, and / or frequency-domain resources for transmitting UE-RS.

[0114] In some embodiments, the UE can obtain downlink resource allocation based on the target AP-RS. The downlink resource allocation includes one or more of the following: downlink common control channel space of the downlink common channel, time-domain resources for transmitting the UE-RS, and / or frequency-domain resources for transmitting the UE-RS. In some embodiments, the UE determines the downlink common control channel space of the downlink common channel, the time-domain resources for transmitting the UE-RS, and / or the frequency-domain resources for transmitting the UE-RS based on the target AP-RS. Then, the UE transmits the UE-RS to the target AP based on the time-domain resources and frequency-domain resources for transmitting the UE-RS. The information carried by the UE-RS is determined according to its purpose; if the UE-RS is used for access, it carries one or more of the following: UE identifier and access request indication, AP-ID of the target AP, and access reason; the access request indication indicates that the purpose of the current UE-RS is to initiate an access request to the network side, for example, 1 bit. If the UE-RS is used to request system messages, it carries the UE identifier and system message request indication. Afterwards, the UE receives the access response sent by the target AP based on the downlink common control channel space of the downlink common channel. The access response carries downlink resource allocation. After receiving the target AP-RS sent by the target AP, the UE can determine the downlink common control channel space, the time-domain resources for sending the UE-RS, and the frequency-domain resources for sending the UE-RS based on the target AP-RS. After determining the time-domain and frequency-domain resources for sending the UE-RS, the UE can further send the UE-RS to the target AP based on these resources. When the AP actively sends a unicast message to obtain access configuration parameters, the UE obtains the access configuration parameters through the unicast message and sends the UE-RS for access. The UE-RS carries one or more of the following: UE identifier and access request indication, target AP identifier and access reason. When requesting the AP to send a unicast message to obtain access configuration parameters, the UE sends the UE-RS to obtain system messages. The UE-RS carries the UE identifier and system message request indication, which instructs the UE to receive access configuration parameters from the AP via unicast. After receiving the UE-RS sent by the UE, the target AP can further determine whether the target AP can access the UE. If the target AP can access the UE, it can send an access response to the UE via the downlink common channel. This access response carries a downlink resource allocation (DL Assignment). Correspondingly, the UE can receive the access response from the target AP based on the downlink common control channel space determined by the target AP-RS.

[0115] Step 2: Based on downlink resource allocation, receive the RRC common configuration information sent by the AP; the RRC common configuration information includes access configuration parameters.

[0116] In some embodiments, after obtaining the downlink resource allocation carried in the access response, the UE can receive RRC common configuration information sent by the target AP based on the downlink resource allocation. The RRC common configuration information includes access configuration parameters. In some embodiments, the UE first obtains the downlink common control channel space for receiving the access response sent by the AP, the time domain resources for sending the UE-RS, and the frequency domain resources for sending the UE-RS through the target AP-RS. Then, when obtaining access configuration parameters by actively sending a unicast message through the AP, the UE waits for the target AP to send the access configuration information via unicast by including an access request indication in the UE-RS access request information. When obtaining access configuration parameters by requesting the AP to send a unicast message, the UE can also actively request the target AP to send the access configuration information via unicast by including a system message request indication in the UE-RS access request information. These two mechanisms enable the UE to flexibly initiate different types of access requests as needed, thereby flexibly obtaining access configuration messages.

[0117] (2) Obtaining access configuration parameters via broadcast messages. When the access configuration parameters are obtained via broadcast, the UE's process for obtaining the access configuration parameters based on this method includes:

[0118] Receive the minimum system message sent by the target AP via broadcast; the minimum system message carries access configuration parameters.

[0119] In some embodiments, when the target AP actively sends a broadcast message to obtain access configuration parameters, the target AP also broadcasts a minimum system message when sending the target AP-RS. The minimum system message carries the access configuration parameters. The UE can receive the minimum system message broadcast by the target AP and obtain the access configuration parameters from it. When obtaining access configuration parameters by requesting the AP to send a broadcast message, the UE determines the time-domain resources and frequency-domain resources for sending the UE-RS based on the target AP-RS. Then, the UE sends the UE-RS to the target AP to request a system message based on the time-domain and frequency-domain resources of the UE-RS. The UE-RS carries the UE identifier and request indication information, including a system message request indication. Afterwards, the UE receives the minimum system message broadcast by the target AP. The minimum system message carries the access configuration parameters. In some embodiments, after receiving the target AP-RS sent by the target AP, the UE can further determine the time-domain resources and frequency-domain resources for sending the UE-RS based on the target AP-RS. Then, after determining the time-domain resources and frequency-domain resources for sending the UE-RS, the UE can further send the UE-RS to the target AP based on these resources. The UE-RS carries the UE identifier and a system message request indication. Upon receiving the UE-RS from the UE, the target AP can broadcast a minimum system message. This minimum system message carries access configuration parameters. Correspondingly, the UE can receive the minimum system message broadcast by the target AP and obtain the access configuration parameters from it. Therefore, when obtaining access configuration parameters by actively sending a broadcast message through the AP, the UE can flexibly obtain the parameters according to its needs, thereby quickly completing the access process and improving overall access efficiency. When obtaining access configuration parameters by requesting the AP to send a broadcast message, the UE directly requests the AP to send a system message carrying access configuration parameters via broadcast through the UE-RS, thus reducing the latency between the UE initiating the access request and obtaining the access configuration parameters.

[0120] As an optional implementation, when the access configuration parameters are obtained through the default method and through broadcast messages, the UE can also perform the following processing procedure:

[0121] Step 1: Based on the access configuration parameters, send an access request message to the target AP via the UE-RS. The access request message carries the UE identifier and / or access request information, which includes one or more of the following: access request indication, the target AP's AP-ID, and the access reason.

[0122] In some embodiments, the UE sends a UE-RS to the target AP based on access configuration parameters. The UE-RS carries a UE identifier and / or access request information, which includes one or more of the following: an access request indication, the AP identifier of the target AP, and an access reason. In some embodiments, the UE sends the UE-RS to the target AP based on the time-domain resources and frequency-domain resources used to send the UE-RS.

[0123] Step two: Based on the access configuration parameters, receive the access response sent by the target AP. The access response carries uplink resource allocation information.

[0124] In some embodiments, after receiving the UE-RS sent by the UE, the target AP can further determine whether it can access the UE. If the target AP can access the UE, it can send an access response to the UE. The access response carries uplink resource allocation. Accordingly, the UE can receive the access response sent by the target AP based on access configuration parameters. In some embodiments, the UE can receive the access response sent by the target AP based on the downlink common control channel space of the downlink common channel.

[0125] Step 3: Based on the uplink resource allocation, send a connection establishment request message to the target AP.

[0126] In some embodiments, after obtaining the uplink resource allocation carried in the access response, the UE can send a connection establishment request message to the target AP based on the uplink resource allocation to request network access. The connection establishment request message includes an RRC (Radio Resource Control) connection establishment request message and / or a NAS (Non-Access Stratum) connection establishment request message.

[0127] As an optional implementation, when obtaining access configuration parameters via unicast messages, the UE can also perform the following processing procedure:

[0128] Step 1: Based on the access configuration parameters, send RRC common configuration confirmation information to the target AP.

[0129] In some embodiments, after receiving the RRC common configuration information, the UE can send RRC common configuration confirmation information to the target AP based on the access configuration parameters to indicate to the target AP that the UE has received the RRC common configuration information.

[0130] As an optional implementation, the UE can send RRC common configuration confirmation information to the target AP in various ways, including the following three methods.

[0131] Method 1: Send HARQ ACK (Hybrid Automatic Repeat request Acknowledgement) feedback to the target AP; whereby HARQ ACK feedback is used to indicate that the UE has received RRC common configuration information.

[0132] Method 2: Receive uplink resource allocation from the target AP, and on the allocated uplink resources, send an RRC message carrying RRC common configuration confirmation information via CCCH (Common Control Channel).

[0133] Method 3: Receive the uplink resource allocation sent by the target AP, and send a MAC CE (Media Access Control Element) carrying RRC common configuration confirmation information on the allocated uplink resources.

[0134] Step 2: Receive the uplink resource allocation sent by the target AP.

[0135] In some embodiments, after receiving the RRC common configuration confirmation information sent by the UE, the target AP may further send uplink resource allocation to the UE. Accordingly, the UE receives the uplink resource allocation sent by the target AP.

[0136] Step 3: Based on the uplink resource allocation, send a connection establishment request message to the target AP.

[0137] In some embodiments, after receiving uplink resource allocation, the UE can send a connection establishment request message to the target AP based on the uplink resource allocation to request network access. The connection establishment request message includes an RRC connection establishment request message and / or a NAS connection establishment request message.

[0138] As an optional implementation, the UE determines the downlink common control channel space for receiving downlink common channels based on the target AP-RS by: determining the downlink common control channel space for receiving downlink common channels based on the time-frequency resource location of the target AP-RS, or the downlink common control channel space parameters included in the AP-RS.

[0139] In some embodiments, after receiving the target AP-RS sent by the target AP, the UE can determine the downlink common control channel space of the downlink common channel based on the time-frequency resource location of the target AP-RS or the downlink common control channel space parameters (i.e., CORESET#0 configuration parameters) included in the target AP-RS.

[0140] As an optional implementation, the UE determines the time domain resources and frequency domain resources for transmitting the UE-RS based on the target AP-RS, including: determining the frequency domain position of the UE-RS based on the downlink frequency point and / or bandwidth of the target AP-RS according to a predetermined fixed offset or correspondence; and determining the time domain position of the UE-RS based on the transmission time point of the target AP-RS according to a predetermined fixed offset or correspondence.

[0141] In some embodiments, the UE determines the frequency position for transmitting the UE-RS based on the downlink frequency point and / or bandwidth of the target AP-RS, according to a fixed offset or correspondence. Simultaneously, the UE determines the time domain position for transmitting the UE-RS based on the transmission time point of the target AP-RS, according to a fixed offset or correspondence. The fixed offset or correspondence is pre-agreed between the UE and the target AP.

[0142] The following will describe in detail another access method provided by the embodiments of this disclosure, with reference to the implementation methods. Figure 3 is a flowchart of another access method provided by the embodiments of this disclosure. The method is applied to an AP, and as shown in Figure 3, the steps are as follows:

[0143] Step 301: Send AP-RS to UE; wherein, AP-RS is used by UE to determine the acquisition method of access configuration parameters based on AP-RS, and to acquire access configuration parameters based on the acquisition method, and the access configuration parameters are used by UE to access the network.

[0144] In some embodiments, the AP periodically transmits a physical layer sequence, AP-RS. The AP-RS is used by the UE to determine the acquisition method for access configuration parameters, and based on this method, to acquire the access configuration parameters. These access configuration parameters are used by the UE to access the network. The transmission period and timing of the AP-RS are defined by the protocol. The AP can be a base station of the radio access network, a relay node, a transmitting terminal of a D2D network, etc.

[0145] As an optional implementation, AP-RS includes AP-ID and necessary access configuration information.

[0146] (1) AP-ID includes one or more of the following: PLMN identifier, base station identifier, cell identifier, and transmission receiving point identifier;

[0147] (2) Necessary access configuration information includes one or more of the following: access denied indication information, downlink common control channel spatial parameters, AP selected channel quality parameters, SI support indication information, read broadcast message indication information, and access indication information based on default configuration.

[0148] As an optional implementation, when the access configuration parameters are obtained via unicast, the AP can also perform the following steps:

[0149] Step 1: Receive the UE-RS sent by the UE. The UE-RS carries the UE identifier and / or access request information. The access request information includes one or more of the following: request indication information, AP identifier, and access reason. The request indication information includes access request indication or system message request indication.

[0150] In some embodiments, when the access configuration parameters are obtained via unicast, after the UE determines the time-domain resources and frequency-domain resources for sending the UE-RS based on the AP-RS, the UE can further send the UE-RS to the AP based on these resources. The UE-RS carries a UE identifier and / or access request information, which includes one or more of a request indication, an AP identifier, and an access reason. When the AP actively sends a unicast message to obtain the access configuration parameters, the UE-RS carries one or more of the UE identifier, an access request indication, the AP identifier of the target AP, and an access reason. When the AP is requested to send a unicast message to obtain the access configuration parameters, the UE-RS carries a UE identifier and a system message request indication. This system message request indication instructs the UE to receive the access configuration parameters from the AP via unicast. Correspondingly, the AP can receive the UE-RS sent by the UE.

[0151] Step two: Send an access response to the UE. The access response includes downlink resource allocation.

[0152] In some embodiments, after receiving the UE-RS sent by the UE, the AP can further determine whether it can access the UE. If the AP can access the UE, it can send an access response to the UE via the downlink common channel. The access response carries downlink resource allocation information.

[0153] Step 3: Based on downlink resource allocation, send RRC common configuration information to the UE. This RRC common configuration information carries access configuration parameters.

[0154] In some embodiments, when the AP sends an access response to the UE, it may further send RRC common configuration information to the UE based on downlink resource allocation. The RRC common configuration information carries access configuration parameters.

[0155] As an optional implementation, when the access configuration parameters are obtained via broadcast, the AP also performs the following:

[0156] The minimum system message is sent to the UE via broadcast. The minimum system message carries access configuration parameters.

[0157] In some embodiments, when obtaining access configuration parameters by actively sending a broadcast message through the AP, the AP also sends a minimum system message via broadcast when sending the AP-RS. The minimum system message carries the access configuration parameters. When obtaining access configuration parameters by sending a broadcast message through the AP, the AP receives the UE-RS sent by the UE. The UE-RS carries the UE identifier and a system message request indication. The AP then sends the minimum system message to the UE via broadcast. The minimum system message carries the access configuration parameters. In some embodiments, when obtaining access configuration parameters by sending a broadcast message through the AP, after the UE determines the time-domain resources and frequency-domain resources for sending the UE-RS based on the AP-RS, it can further send the UE-RS to the AP based on these resources. The UE-RS carries the UE identifier and a system message request indication. Accordingly, the AP can receive the UE-RS sent by the UE. Then, after receiving the UE-RS, the AP can send the minimum system message to the UE via broadcast. The minimum system message carries the access configuration parameters.

[0158] As an optional implementation, when the access configuration parameters are obtained using the default method and broadcast method, the AP can also perform the following steps:

[0159] Step 1: Receive the access request message sent by the UE through the UE-RS. The access request message carries the UE identifier and / or access request information, which includes one or more of the following: access request indication, AP identifier, and access reason.

[0160] In some embodiments, when the access configuration parameters are obtained via default or broadcast methods, after the UE determines the time-domain resources and frequency-domain resources for sending the UE-RS based on the AP-RS, the UE can send the UE-RS to the AP based on these resources. The UE-RS carries a UE identifier (UE-ID) and / or access request information, where the access request information includes one or more of an access request indication, an AP identifier, and an access reason. Correspondingly, the AP can receive the UE-RS sent by the UE.

[0161] Step two: Send an access response to the UE. The access response includes uplink resource allocation.

[0162] In some embodiments, after receiving the UE-RS sent by the UE, the AP can further determine whether the AP can access the UE. If the AP can access the UE, the AP can send an access response to the UE. The access response carries uplink resource allocation.

[0163] Step 3: Receive the connection establishment request message sent by the UE based on the uplink resource allocation.

[0164] In some embodiments, after obtaining the uplink resource allocation carried in the access response, the UE can send a connection establishment request message to the AP based on the uplink resource allocation to request network access. The connection establishment request message includes an RRC connection establishment request message and / or a NAS connection establishment request message. Correspondingly, the AP can receive the connection establishment request message sent by the UE based on the uplink resource allocation and execute subsequent access procedures.

[0165] As an optional implementation, when the access configuration parameters are obtained via unicast, the AP also performs the following steps:

[0166] Step 1: Receive the RRC common configuration confirmation information sent by the UE.

[0167] In some embodiments, when the access configuration parameters are obtained via unicast, after receiving the RRC common configuration information, the UE can send RRC common configuration confirmation information to the AP. This RRC common configuration confirmation information indicates to the AP that the UE has received the RRC common configuration information. Correspondingly, the AP can receive the RRC common configuration confirmation information sent by the UE.

[0168] As an optional implementation, when the RRC common configuration confirmation information is carried by the RRC message on the CCCH or by the MAC CE, the AP sends an uplink resource allocation to the UE for sending the RRC common configuration confirmation information.

[0169] Step 2: Send uplink resource allocation to the UE.

[0170] In some embodiments, after receiving the RRC common configuration confirmation information sent by the UE, the AP may further send uplink resource allocation to the UE.

[0171] Step 3: Receive the connection establishment request message sent by the UE based on the uplink resource allocation, and perform access processing on the UE based on the connection establishment request message.

[0172] In some embodiments, after receiving uplink resource allocation, the UE can send a connection establishment request message to the AP based on the uplink resource allocation to request network access. The connection establishment request message includes an RRC connection establishment request message and / or a NAS connection establishment request message. Correspondingly, the AP can receive the connection establishment request message sent by the UE based on the uplink resource allocation and execute subsequent access procedures.

[0173] This disclosure provides the following five implementation examples:

[0174] Implementation Example 1: Based on the default correspondence between AP-RS and access configuration parameters, the terminal determines the access configuration parameters to access the network, as shown in Figure 4. The processing procedure is as follows:

[0175] Step 401: The base station (AP) sends the AP-RS. The AP-RS includes the AP identifier (AP-ID) and necessary access information; the necessary access information includes whether access is prohibited indication information (bar), downlink common control channel spatial parameters (such as CORESET#0 configuration parameters), and AP selected channel quality parameters.

[0176] Step 402: The terminal receives the AP-RS according to the period and transmission time specified in the protocol. The terminal synchronizes its time and frequency with the AP according to the received AP-RS time and frequency location. The terminal selects the AP to access and determines the access configuration parameters based on the default correspondence between the AP-RS and the access configuration parameters.

[0177] The terminal selects the access point (AP) based on one or a combination of the following:

[0178] (1) If the target AP-RS includes AP selection channel quality parameters, then select the AP that meets the channel quality threshold;

[0179] (2) If the target AP-RS does not include access denial indication information, or if the AP-RS includes access denial indication information that indicates access is allowed, then select the AP.

[0180] Step 403: The terminal sends a UE-RS to the AP to initiate the access procedure. The UE-RS includes the UE identifier (UE-ID) and access request information; the access request information includes one or more of the following: access request indication, AP-ID of the target access point, and access reason.

[0181] Step 404: The AP receives the UE-RS sent by the terminal, processes the received UE-RS, and determines that the terminal can access the network.

[0182] Step 405: The AP sends an access response to the terminal. This access response includes an uplink resource allocation (UL grant). The UL grant is based on the uplink resource configuration (such as center frequency, bandwidth, SCS (Subcarrier Spacing), MCS (Modulation and Coding Scheme) format, determined according to the default rules of the AP-RS and uplink resources. The UL grant allocates a portion of the available resources within this uplink resource configuration.

[0183] Step 406: The terminal sends an RRC establishment request message and / or a NAS establishment request message on the uplink resources allocated by the AP.

[0184] Step 407: The AP processes the RRC establishment request message sent by the terminal.

[0185] In step 408, the AP determines that an RRC connection can be established with the terminal and sends an RRC establishment message to the terminal. This RRC establishment message carries terminal-specific configurations, such as bearer configuration, protocol stack configuration, and carrier configuration. In this step, the terminal obtains complete information about the AP and its terminal-specific configurations.

[0186] Step 409: The terminal processes the RRC establishment message, applies the parameters configured by the AP, and generates an RRC establishment completion message.

[0187] Step 410: The terminal sends an RRC establishment complete message to the AP.

[0188] Step 411: The AP processes the NAS establishment request message sent by the terminal.

[0189] Step 412: The AP sends the NAS establishment request message sent by the terminal to the core network.

[0190] Step 413: The core network processes the NAS establishment request message and determines that a connection can be established with the terminal.

[0191] Step 414: The core network sends a NAS establishment message to the AP.

[0192] Step 415: The AP processes the NAS establishment message of the core network and determines the corresponding terminal.

[0193] Step 416: The AP sends a NAS establishment message to the terminal.

[0194] Step 417: The terminal processes the NAS establishment message forwarded by the AP and applies the NAS configuration of the core network. A NAS establishment complete message is then generated.

[0195] Step 418: The terminal sends a NAS establishment completion message to the core network through the AP to confirm that the connection has been established.

[0196] Implementation Example 2: The terminal determines the access configuration parameters based on AP-RS and AP unicast methods and accesses the network, as shown in Figure 5. The processing procedure is as follows:

[0197] Step 501: The base station (AP) sends the AP-RS. The AP-RS includes the AP identifier (AP-ID) and necessary access information; the necessary access information includes whether access is prohibited indication information (bar), downlink common control channel spatial parameters (such as CORESET#0 configuration parameters), and AP selected channel quality parameters.

[0198] Step 502: The terminal receives the AP-RS according to the period and transmission time specified in the protocol. The terminal synchronizes its time and frequency with the AP according to the received AP-RS time and frequency location. The terminal selects the target AP to access and determines the time domain resources and frequency domain resources for sending the UE-RS based on the target AP-RS.

[0199] The terminal selects the access point (AP) based on one or a combination of the following:

[0200] (1) If the target AP-RS includes AP selection channel quality parameters, then select the AP that meets the channel quality threshold;

[0201] (2) If the target AP-RS does not include access denial indication information, or if the target AP-RS includes access denial indication information that indicates access is allowed, then select the AP.

[0202] Step 503: The terminal sends a UE-RS to the AP to initiate the access procedure. The UE-RS includes the UE identifier (UE-ID) and access request information; the access request information includes one or more of the following: access request indication, AP-ID of the target access point, and access reason.

[0203] Step 504: The AP receives the UE-RS sent by the terminal, processes the received UE-RS, and determines that the terminal can access the network.

[0204] Step 505: The AP sends an access response to the terminal. This access response includes a downlink resource allocation (DL Assignment). This DL Assignment is a downlink resource configuration (center frequency, bandwidth, SCS, MCS format, etc.) determined based on the default rules between the AP-RS and downlink resources. The DL Assignment allocates a portion of the available resources within this downlink resource configuration.

[0205] Step 506: The AP sends RRC common configuration information (which can be regarded as MSI (Minimal System Information)) on the allocated downlink resources. The RRC common configuration information includes at least access parameter configuration, such as access control information (UAC (Unified Access Control)) and physical layer uplink and downlink resource configuration.

[0206] Step 507: The terminal receives the RRC common configuration information sent by the AP; in some embodiments, the terminal can determine whether it can access the AP based on the UAC parameters.

[0207] Step 508: The terminal sends RRC common configuration confirmation information to the AP.

[0208] The implementation of this RRC public configuration confirmation information can include any of the following methods:

[0209] (1) The terminal sends downlink transmission HARQ ACK feedback to the AP. The resource for sending HARQ feedback is determined by the RRC common configuration information sent in step 506.

[0210] (2) The terminal uses the RRC message carried on the CCCH to send back the RRC common configuration confirmation information; (in this way, the AP needs to allocate uplink transmission resources for the terminal between steps 505 and 508);

[0211] (3) The terminal uses the MAC layer control command MAC CE to carry the RRC common configuration confirmation information (in this way, the AP also needs to allocate uplink transmission resources for the terminal between steps 505 and 508).

[0212] Step 509: After confirming that the terminal has received the RRC common configuration information, the AP sends an uplink resource allocation to the terminal. The uplink resource allocation may carry an uplink resource indication and / or an uplink timing advance.

[0213] Step 510: The terminal sends an RRC establishment request message and / or a NAS establishment request message on the uplink resources allocated by the AP.

[0214] Step 511: The AP processes the RRC establishment request message sent by the terminal.

[0215] In step 512, the AP determines that an RRC connection can be established with the terminal and sends an RRC establishment message to the terminal. This RRC establishment message carries terminal-specific configurations, such as bearer configuration, protocol stack configuration, and carrier configuration. The terminal obtains complete information about the AP and its terminal-specific configurations.

[0226] Implementation Example 3: In Implementation Example 3, the terminal determines the access configuration parameters based on the minimum system messages broadcast by AP-RS and AP, and accesses the network, as shown in Figure 6. The processing procedure is as follows:

[0227] Step 601, the base station (AP) sends the AP-RS. The AP-RS includes the AP identifier (AP-ID) and necessary access information; the necessary access information includes indications of whether broadcast messages need to be read and / or whether access based on the default configuration is allowed.

[0228] Step 602: The AP sends a minimal system message via broadcast to notify the terminal of the access configuration parameters.

[0229] Step 603: The terminal receives the AP-RS according to the period and transmission time specified in the protocol. The terminal synchronizes its time and frequency with the AP according to the time and frequency location of the received AP-RS. If the AP-RS includes indication information for access based on the default configuration, the process described in Implementation Example 1 is executed. Otherwise, the terminal reads the broadcast minimum system message to obtain the access configuration parameters. The terminal selects the target AP based on the access configuration parameters and the received AP-RS.

[0230] Step 604: The terminal sends a UE-RS to the AP to initiate the access procedure. The UE-RS includes the UE identifier (UE-ID) and access request information, which includes one or more of the following: access request indication, AP-ID of the target access point, and access reason.

[0231] Step 605: The AP receives the UE-RS sent by the terminal. The AP processes the UE-RS and determines that the terminal can access the network.

[0232] Step 606: The AP sends an access response to the terminal, wherein the access response includes an uplink resource allocation (UL) grant.

[0233] Step 607: The terminal sends an RRC establishment request message and / or a NAS establishment request message on the uplink resource allocation.

[0234] Step 608: The AP processes the RRC establishment request message sent by the terminal.

[0235] In step 609, the AP determines that an RRC connection can be established with the terminal and sends an RRC establishment message to the terminal. This RRC establishment message carries terminal-specific configurations, such as bearer configuration, protocol stack configuration, and carrier configuration. The terminal obtains complete information about the AP and its terminal-specific configurations.

[0236] Step 610: The terminal processes the RRC establishment message, applies the parameters configured by the AP, and generates an RRC establishment completion message.

[0237] Step 611: The terminal sends an RRC establishment complete message to the AP.

[0238] Step 612: The AP processes the NAS establishment request message sent by the terminal.

[0239] Step 613: The AP sends the NAS establishment request message sent by the terminal to the core network.

[0240] Step 614: The core network processes the NAS establishment request message and determines that a connection can be established with the terminal.

[0241] Step 615: The core network sends a NAS establishment message to the AP.

[0242] Step 616: The AP processes the NAS establishment message of the core network and determines the corresponding terminal.

[0243] Step 617: The AP sends a NAS establishment message to the terminal.

[0244] Step 618: The terminal processes the NAS establishment message forwarded by the AP, applies the NAS configuration of the core network, and generates a NAS establishment completion message.

[0245] Step 619: The terminal sends a NAS establishment completion message to the core network through the AP to confirm that the connection has been established.

[0246] Implementation Example 4: The terminal determines the access configuration parameters based on the minimum system message broadcast by AP-RS and the requested AP, and accesses the network, as shown in Figure 7. The processing procedure is as follows:

[0247] Step 701, the base station (AP) sends the AP-RS. The AP-RS includes the AP identifier (AP-ID) and necessary access information; the necessary access information includes an indication of whether to read broadcast messages and / or whether to allow access based on the default configuration.

[0248] Step 702: The terminal receives the AP-RS according to the period and transmission time specified in the protocol. The terminal synchronizes its time and frequency with the AP according to the received AP-RS time and frequency location, and selects the AP to access.

[0249] Step 703: The terminal sends a UE-RS to the AP. The UE-RS includes the UE identifier (UE-ID) and access request information, which includes a system message request indication. The frequency location of the UE-RS corresponds to the frequency location of the AP-RS sent by the AP that needs to access.

[0250] Step 704: The AP sends a minimal system message via broadcast to notify the terminal of the access configuration parameters.

[0251] Step 705: The terminal reads the broadcast minimum system message to obtain access configuration parameters. Based on the access configuration parameters and the received AP-RS, the terminal determines the AP to access. For example, even if the terminal determines in step 701 that AP1's channel quality is good enough, but the terminal determines that the AP cannot be accessed based on the Access Control Message (UAC) in AP1's access configuration parameters, the terminal still needs to terminate the access process for AP1. The terminal sends a UE-RS to the network side to initiate the access process. The UE-RS includes the UE-ID and access request information, which includes one or more of the following: access request indication, target access point's AP-ID, and access reason.

[0252] Step 706: The AP receives the UE-RS sent by the terminal. The AP processes the received UE-RS and determines that the terminal can access the network.

[0253] Step 707, the AP sends an access response to the terminal, wherein the access response includes an uplink resource allocation (UL) grant.

[0254] Step 708: The terminal sends an RRC establishment request message and / or a NAS establishment request message on the uplink resources allocated by the AP.

[0255] Step 709: The AP processes the RRC establishment request message sent by the terminal.

[0256] In step 710, the AP determines that an RRC connection can be established with the terminal and sends an RRC establishment message to the terminal. This RRC establishment message carries terminal-specific configurations, such as bearer configuration, protocol stack configuration, and carrier configuration. Based on this RRC establishment message, the terminal can obtain complete information about the AP and its terminal-specific configurations.

[0257] Step 711: The terminal processes the RRC establishment message, applies the parameters configured by the AP, and generates an RRC establishment completion message.

[0258] Step 712: The terminal sends an RRC establishment complete message to the AP.

[0259] Step 713: The AP processes the NAS establishment request message sent by the terminal.

[0260] Step 714: The AP sends the NAS establishment request message sent by the terminal to the core network.

[0261] Step 715: The core network processes the NAS establishment request message and determines that a connection can be established with the terminal.

[0262] Step 716: The core network sends a NAS establishment message to the AP.

[0263] Step 717: The AP processes the NAS establishment message of the core network and determines the corresponding terminal.

[0264] Step 718: The AP sends a NAS establishment message to the terminal.

[0265] Step 719: The terminal processes the NAS establishment message forwarded by the AP, applies the NAS configuration of the core network, and generates a NAS establishment completion message.

[0266] Step 720: The terminal sends a NAS establishment completion message to the core network through the AP to confirm that the connection has been established.

[0267] Implementation Example 5: The terminal determines the access configuration parameters to access the network based on the system message sent by AP-RS and the requesting AP unicast, as shown in Figure 8. The processing procedure is as follows:

[0268] Step 801: The base station (AP) sends the AP-RS. The AP-RS includes the AP identifier (AP-ID) and necessary access information; the necessary access information includes whether access is prohibited indication information (bar), downlink common control channel spatial parameters (such as CORESET#0 configuration parameters), and AP selected channel quality parameters.

[0269] Step 802: The terminal receives the AP-RS according to the period and transmission time specified in the protocol. The terminal synchronizes its time and frequency with the AP according to the time and frequency location of the received AP-RS. The terminal selects the AP to access and determines the time domain resources and frequency domain resources for sending the UE-RS based on the AP-RS.

[0270] The terminal selects the access point (AP) based on one or a combination of the following:

[0271] (1) If the AP-RS includes AP selection channel quality parameters, then select the AP that meets the channel quality threshold;

[0272] (2) If the AP-RS does not include access denial indication information, or if the AP-RS includes access denial indication information that indicates access is allowed, then select the AP.

[0273] Step 803: The terminal sends a UE-RS to the AP to initiate the access procedure. The UE-RS includes the UE identifier (UE-ID) and access request information; the access request information includes a system information request indication.

[0274] Step 804: The AP receives the UE-RS sent by the terminal, processes the received UE-RS, and determines that the terminal can access the terminal.

[0275] Step 805: The AP sends an access response to the terminal. This access response includes a downlink resource allocation (DL Assignment). The DL Assignment includes the downlink resource configuration (center frequency, bandwidth, SCS, MCS format, etc.) determined based on the default rules between the AP-RS and downlink resources. The DL Assignment represents a portion of the available resources allocated within this downlink resource configuration.

[0276] Step 806: The AP sends RRC common configuration information (which can be regarded as MSI (Minimal System Information)) on the allocated downlink resources. The RRC common configuration information includes at least access parameter configuration, such as access control information (UAC (Unified Access Control)) and physical layer uplink and downlink resource configuration.

[0277] Step 807: The terminal receives the RRC common configuration information sent by the AP. In some embodiments, the terminal can determine whether it can access the AP based on the UAC parameters.

[0278] Step 808: The terminal sends RRC common configuration confirmation information to the AP.

[0279] The terminal may send the RRC common configuration confirmation information to the AP in any of the following ways:

[0280] (1) The terminal sends downlink transmission HARQ ACK feedback to the AP. The resource for sending HARQ feedback is determined by the RRC common configuration information sent in step 806.

[0281] (2) The terminal uses the RRC message carried on the CCCH to send back the RRC common configuration confirmation information; (in this way, the AP also needs to allocate uplink transmission resources for the terminal between steps 805 and 808);

[0282] (3) The terminal uses the MAC layer control command MAC CE to carry the RRC common configuration confirmation information (in this way, the AP also needs to allocate uplink transmission resources for the terminal between step 805 and step 808).

[0283] Step 809: After confirming that the terminal has received the RRC common configuration information, the AP sends an uplink resource allocation to the terminal. The uplink resource allocation may carry an uplink resource indication and / or an uplink timing advance.

[0284] Step 810: The terminal sends an RRC establishment request message and / or a NAS establishment request message on the uplink resources allocated by the AP.

[0285] Step 811: The AP processes the RRC establishment request message sent by the terminal.

[0286] In step 812, the AP determines that an RRC connection can be established with the terminal and sends an RRC establishment message to the terminal. This RRC establishment message carries terminal-specific configurations, such as bearer configuration, protocol stack configuration, and carrier configuration. Based on this RRC establishment message, the terminal obtains complete information about the AP and its terminal-specific configurations.

[0287] Step 813: The terminal processes the RRC establishment message, applies the parameters configured by the AP, and generates an RRC establishment completion message.

[0288] Step 814: The terminal sends an RRC establishment complete message to the AP.

[0289] Step 815: The AP processes the NAS establishment request message sent by the terminal.

[0290] Step 816: The AP sends the NAS establishment request message sent by the terminal to the core network.

[0291] Step 817: The core network processes the NAS establishment request message and determines that a connection can be established with the terminal.

[0292] Step 818: The core network sends a NAS establishment message to the AP.

[0293] Step 819: The AP processes the NAS establishment message of the core network and determines the corresponding terminal.

[0294] Step 820: The AP sends a NAS establishment message to the terminal.

[0295] Step 821: The terminal processes the NAS establishment message forwarded by the AP, applies the NAS configuration of the core network, and generates a NAS establishment completion message.

[0296] Step 822: The terminal sends a NAS establishment completion message to the core network through the AP to confirm that the connection has been established.
