[0073] In 4G networks, the public network and the High Speed ​​Dedicated Network (HSDN) are deployed on different frequencies. This is achieved by adding neighboring cell lists for both the public and dedicated networks, along with the priority of each neighboring cell, to the System Information Block (SIB) 5 message. This constrains the access behavior of public network users to HSDN cells. In 5G scenarios, terminal traffic demands are higher, requiring the HSDN to meet the capacity absorption needs of the surrounding public network during off-peak hours. However, unlike 4G, 5G networks deploy the public and HSDN on the same frequency. Therefore, it's impossible to prioritize public and HSDN cells based on frequency; instead, priorities are determined by the Physical Cell Identifier (PCI). Because there are many neighboring cells in the 5G network, the processing latency of the terminal is relatively long. Moreover, the scheme based on PCI tag priority can only guarantee that public network users do not access high-speed private network cells. It cannot enable public network users to access or switch out of high-speed private network cells at any time when the high-speed private network is idle. This causes public network users to access high-speed private network cells indiscriminately, which affects the communication efficiency of high-speed private network users.

[0074] Based on this, the cell access method, apparatus, base station, terminal, and storage medium provided in this application embodiment enable the terminal to initiate a random access procedure to the industry network base station or private network base station. The industry network base station or private network base station determines whether to access the terminal on the PRACH resource where the terminal initiates the random access procedure based on the terminal's mobility state. This allows the industry network base station or private network base station to decide whether to allow the terminal to access based on the terminal's mobility state in the idle state, thereby avoiding public network users accessing private network cells indiscriminately, reducing the impact of public network users on the industry network or private network, and ensuring the communication efficiency of industry network users or private network users.

[0075] The present application will now be described in further detail with reference to the accompanying drawings and embodiments.

[0076] This application provides a cell access method applied to a base station, such as... Figure 1 As shown, the method includes:

[0077] Step 101: Based on the terminal's first mobility state, determine whether to access the terminal on the PRACH resource where the terminal initiates a random access procedure.

[0078] Here, the base station is an industry network base station or a private network base station, such as a high-speed railway private network base station. When the terminal initiates a random access procedure to the base station, it is in an idle state. The base station, based on the terminal's current first mobility state, decides whether to allow access to the terminal on the PRACH resource where the random access was initiated. In practical applications, the terminal's mobility state includes at least a high-mobility state, a medium-mobility state, or a low-mobility state. After determining the terminal's first mobility state, the base station makes the following decisions based on that state:

[0079] Determine whether to allow the terminal to access the PRACH resource on which the terminal initiated a random access procedure; or,

[0080] If it is determined that access to the terminal is permitted on the PRACH resource where the terminal initiates a random access procedure, then it is determined whether to schedule the terminal; or,

[0081] If it is determined that the terminal is accessed and scheduled, at least one of the scheduling resources configured for the terminal and the scheduling priority corresponding to the terminal is determined.

[0082] In 5G New Radio (NR), the gNB configures PRACH common resources for each cell based on a set of prach-RootSequenceIndex parameters, using the length of the random access preamble sequence (839 or 139), for accessing public network users. In practical applications, industry network base stations or private network base stations also configure a set of PRACH resources for each cell. In this case, the terminal in idle state reports its first mobility status to the base station, and the base station determines whether to access the terminal on the corresponding PRACH resource based on the terminal's first mobility status.

[0083] Based on this, in one embodiment, the method further includes:

[0084] The first mobility state is determined based on the first message sent by the terminal; wherein...

[0085] The first message carries a first identifier that represents the first mobility state.

[0086] The first message includes either an MSG3 message or an MSG5 message.

[0087] Here, in the idle state, the terminal determines its first mobility state and actively informs the base station of this state by sending a first message carrying a first identifier. This first identifier represents the terminal's current mobility state. Sending this first message occurs during the terminal's random access initiation process. For example, if the terminal's first mobility state is high-speed mobility, the terminal adds a "highspeed" identifier to the InitialUE-Identity information element of the RRCsetuprequent message (MSG3 message) during the access process. This "highspeed" identifier indicates that the terminal is currently in a high-speed mobility state. In practical applications, if the terminal loses connection, the "highspeed" identifier is still configured after the terminal regains online status; if the terminal is powered off and then restarted, the "highspeed" identifier is set to NULL.

[0088] In this way, the base station can confirm the first mobility status of the terminal in the idle state through the first identifier reported by the terminal, and make corresponding decisions based on the first mobility status.

[0089] In one embodiment, the base station is configured with a first PRACH resource and a second PRACH resource; the first PRACH resource is for accessing terminals that are not in a high-speed mobile state; and the second PRACH resource is for accessing terminals that are in a high-speed mobile state.

[0090] The method further includes:

[0091] The first mobility state is determined based on the resources of the MSG1 message of PRACH sent by the terminal.

[0092] Here, industry network base stations or private networks configure two sets of PRACH resources for each cell by adding a `prach-RootSequenceIndexhighspeed` parameter to the `prach-RootSequenceIndex` parameter. One set of PRACH resources corresponds to terminals not in high-speed mobility (i.e., ordinary users); the other set of PRACH resources corresponds to terminals in high-speed mobility (i.e., high-speed users). In practical applications, the base station simultaneously sends both sets of PRACH resources in the System Information Block (SIB) 1 message. The terminal, based on its current first mobility state, selects the PRACH resource corresponding to that first mobility state to initiate a random access procedure with the base station. Therefore, by determining the resources in the MSG1 message of the PRACH sent by the terminal, the base station can determine the terminal's first mobility state.

[0093] In one embodiment, the configuration methods for the two different sets of PRACH resources include, but are not limited to:

[0094] The first PRACH resource and the second PRACH resource are located in different time domain locations or frequency domain locations; or,

[0095] The first PRACH resource and the second PRACH resource use different random access sequence numbers; or...

[0096] The first PRACH resource and the second PRACH resource use different random access sequence formats.

[0097] Figure 2 A schematic diagram illustrating the random access process between a terminal and a base station is shown. (Refer to...) Figure 2 The random access process includes:

[0098] Step 201: The terminal sends an MSG1 message to the base station.

[0099] Step 202: The base station sends an MSG2 message to the terminal, which is to send a Random Access Response (RAR) to the terminal.

[0100] Step 203: The terminal sends an MSG3 message to the base station.

[0101] Step 204: The base station sends an MSG4 message to the terminal.

[0102] In the case where the base station configures two different sets of PRACH resources for each cell, after receiving the MSG1 message, the base station determines the terminal's first mobility state based on the resources corresponding to the MSG1 message sent by the terminal. In the case where the base station configures one set of PRACH resources for each cell, after receiving the MSG3 message sent by the terminal, the base station determines the terminal's first mobility state based on the first identifier carried in the MSG3 message.

[0103] As described above, after determining the first mobility state of the terminal, the base station can make the following decisions regarding the random access procedure initiated by the terminal: determining whether to access the terminal on the PRACH resource where the random access procedure was initiated. If the base station allows access to the terminal on the PRACH resource where the random access procedure was initiated, then the MSG4 message sent by the base station to the terminal will migrate the terminal to the connected state. If the base station does not allow access to the terminal on the PRACH resource where the random access procedure was initiated, then, in one embodiment, the method further includes:

[0104] In the event that access to the terminal is denied, the MSG4 message carries the first piece of information; wherein,

[0105] The first piece of information indicates the reason for refusing access to the terminal.

[0106] In other words, when the base station does not allow the terminal to access the corresponding PRACH resource, the base station's MSG4 message, i.e., the RRC Connection Reject message, carries the reason for rejecting the terminal's access, so as to prevent the terminal from repeatedly initiating the random access process to the base station.

[0107] In practical applications, when a terminal accesses a cell, it is in a connected state. In the connected state, the terminal can report its capabilities based on the UE-NR-Capability field, that is, by adding an identifier representing the terminal's mobility state to the UE-NR-Capability field. When the terminal initiates a cell handover, the target base station can also determine whether to access the terminal based on the terminal's current second mobility state. Therefore, in one embodiment, the method further includes:

[0108] When the terminal is in a connected state, the current second mobility state of the terminal is determined based on the handover command sent by the terminal, so that the target base station can decide whether to hand over the terminal based on the second mobility state; wherein,

[0109] The switching command carries a second identifier that represents the second mobility state.

[0110] In practical applications, the terminal carries a second identifier representing its current second mobility state within the handover command message, and interacts with the target base station via the S1, Xn, or X2 interface to determine whether to allow the terminal to hand over to its cell. Here, the target base station includes, but is not limited to, public network base stations, private network base stations, or industry network base stations.

[0111] In one embodiment, the method further includes:

[0112] The second piece of information is carried in the switch reply message; among which,

[0113] The second information indicates the reason for rejecting the terminal switching.

[0114] In practical applications, when the target base station refuses the terminal's handover to a subordinate cell, the target base station sends the reason for refusing the handover to the source base station of the terminal. The source base station carries the reason for refusing the handover in the corresponding handover reply message to avoid the terminal repeatedly requesting to handover to the target base station.

[0115] Correspondingly, embodiments of this application also provide a cell access method, applied to a terminal, such as... Figure 3As shown, the method includes:

[0116] Step 301: Determine the first mobility state of the terminal.

[0117] Here, the terminal determines its current first mobility state by the frequency offset of the downlink reference signal or by the number of handovers within a set time period. In practical applications, the terminal's mobility state includes at least a high-mobility state, a medium-mobility state, or a low-mobility state.

[0118] Step 302: Initiate a random access procedure to the base station so that the base station determines whether to access the terminal based on the first mobility state.

[0119] The base station is an industry network base station or a private network base station, such as a high-speed railway private network base station. Here, the terminal initiates a random access procedure to the base station. At this time, the terminal is in an idle state. Based on the terminal's first mobility state, the base station decides whether to allow the terminal to access the PRACH resource on which the terminal initiated the random access. After determining the terminal's first mobility state, the decisions made by the base station based on the terminal's first mobility state include:

[0120] Determine whether to allow the terminal to access the PRACH resource on which the terminal initiated a random access procedure; or,

[0121] If it is determined that access to the terminal is permitted on the PRACH resource where the terminal initiates a random access procedure, then it is determined whether to schedule the terminal; or,

[0122] If it is determined that the terminal is accessed and scheduled, at least one of the scheduling resources configured for the terminal and the scheduling priority corresponding to the terminal is determined.

[0123] In practical applications, industry network base stations or private network base stations configure a set of PRACH resources for each cell. In this case, the terminal in the idle state reports the first mobility status to the base station, and the base station determines whether to access the terminal on the corresponding PRACH resource based on the terminal's first mobility status.

[0124] Based on this, in one embodiment, the method further includes:

[0125] When initiating a random access procedure to the base station, the method includes:

[0126] A first message is sent to the base station; the first message carries a first identifier representing the first mobility state.

[0127] The first message includes either an MSG3 message or an MSG5 message.

[0128] Here, in the idle state, the terminal determines its first mobility state and actively informs the base station of this state by sending a first message carrying a first identifier. This first identifier represents the terminal's current mobility state. Sending this first message occurs during the terminal's random access initiation process. For example, if the terminal's first mobility state is high-speed mobility, the terminal adds a "highspeed" identifier to the InitialUE-Identity information element of the RRCsetuprequent message (MSG3 message) during the access process. This "highspeed" identifier indicates that the terminal is currently in a high-speed mobility state. In practical applications, if the terminal loses connection, the "highspeed" identifier is still configured after the terminal regains online status; if the terminal is powered off and then restarted, the "highspeed" identifier is set to NULL.

[0129] In this way, the base station can confirm the first mobility status of the terminal in the idle state through the first identifier reported by the terminal, and make corresponding decisions based on the first mobility status.

[0130] In one embodiment, the base station is configured with a first PRACH resource and a second PRACH resource; the first PRACH resource is for accessing terminals that are not in a high-speed mobile state; and the second PRACH resource is for accessing terminals that are in a high-speed mobile state.

[0131] The process of initiating random access to the base station includes:

[0132] Select to initiate a random access procedure to the base station on the PRACH resource corresponding to the first mobility state.

[0133] Here, industry network base stations or private networks configure two sets of PRACH resources for each cell by adding a `prach-RootSequenceIndexhighspeed` parameter to the `prach-RootSequenceIndex` parameter. One set of PRACH resources corresponds to terminals not in high-speed mobility (i.e., ordinary users); the other set of PRACH resources corresponds to terminals in high-speed mobility (i.e., high-speed users). In practical applications, the base station simultaneously sends both sets of PRACH resources in the System Information Block (SIB) 1 message. The terminal, based on its current first mobility state, selects the PRACH resource corresponding to that first mobility state to initiate a random access procedure with the base station. Therefore, by determining the resources in the MSG1 message of the PRACH sent by the terminal, the base station can determine the terminal's first mobility state.

[0134] In one embodiment, the configuration methods for the two different sets of PRACH resources include, but are not limited to:

[0135] The first PRACH resource and the second PRACH resource are located in different time-domain or frequency-domain locations; or...

[0136] The first PRACH resource and the second PRACH resource use different random access sequence numbers; or...

[0137] The first PRACH resource and the second PRACH resource use different random access sequence formats.

[0138] As described above, after determining the first mobility state of the terminal, the base station can make the following decisions regarding the random access procedure initiated by the terminal: determining whether to access the terminal on the PRACH resource where the random access procedure was initiated. If the base station allows access to the terminal on the PRACH resource where the random access procedure was initiated, then the MSG4 message sent by the base station to the terminal will migrate the terminal to the connected state. If the base station does not allow access to the terminal on the PRACH resource where the random access procedure was initiated, then, in one embodiment, the method further includes:

[0139] Receive the MSG4 message sent by the base station; wherein,

[0140] When the base station refuses to access the terminal, the MSG4 message carries first information; the first information indicates the reason for refusing to access the terminal.

[0141] In other words, when the base station does not allow the terminal to access the corresponding PRACH resource, the base station's MSG4 message, i.e., the RRC Connection Reject message, carries the reason for rejecting the terminal's access, so as to prevent the terminal from repeatedly initiating the random access process to the base station.

[0142] In practical applications, when a terminal accesses a cell, it is in a connected state. In the connected state, the terminal can report its capabilities based on the UE-NR-Capability field, that is, by adding an identifier representing the terminal's mobility state to the UE-NR-Capability field. When the terminal initiates a cell handover, the target base station can also determine whether to access the terminal based on the terminal's current second mobility state. Therefore, in one embodiment, the method further includes:

[0143] When the terminal is in a connected state, a handover command is sent to the base station; wherein the handover command carries a second identifier representing the current second mobility state of the terminal, so that the target base station can decide whether to hand over the terminal based on the second mobility state.

[0144] In practical applications, the terminal carries a second identifier representing its current second mobility state within the handover command message, and interacts with the target base station via the S1, Xn, or X2 interface to determine whether to allow the terminal to hand over to its cell. Here, the target base station includes, but is not limited to, public network base stations, private network base stations, or industry network base stations.

[0145] In one embodiment, the method further includes:

[0146] Receive the handover response message sent by the base station; wherein,

[0147] The handover response message carries a second piece of information; the second piece of information indicates the reason for rejecting the terminal handover.

[0148] In practical applications, when the target base station refuses the terminal's handover to a subordinate cell, the target base station sends the reason for refusing the handover to the source base station of the terminal. The source base station carries the reason for refusing the handover in the corresponding handover reply message to avoid the terminal repeatedly requesting to handover to the target base station.

[0149] The cell access method provided in this application embodiment involves a terminal initiating a random access procedure to an industry network base station or a private network base station. The industry network base station or private network base station determines whether to access the terminal on the PRACH resource where the random access procedure was initiated based on the terminal's mobility state. This allows the industry network base station or private network base station to decide whether to allow the terminal to access based on the terminal's mobility state in the idle state. This avoids public network users accessing private network cells indiscriminately, reduces the impact of public network users on the industry network or private network, ensures the communication efficiency of industry network users or private network users, and avoids the reduction in communication efficiency caused by ping-pong handover of the terminal. Furthermore, when the base station configures one set of PRACH resources for each cell, the base station can confirm the first mobility state of the terminal in the idle state through the first identifier actively reported by the terminal. When the base station configures two different sets of PRACH resources for each cell, the first mobility state of the terminal can be determined by determining the resources of the MSG1 message in the PRACH sent by the terminal. In other words, in this embodiment, the terminal can actively report its own mobility state to the base station in the idle state, and the base station can decide whether to allow the terminal to access the network when the terminal is in the idle state without waiting for the terminal to enter the connected state, which improves the speed of cell access and brings about improvements in network performance and user experience.
