Description

Divisional application statement

[0001] This application is a divisional application of Chinese invention patent application No. 202380008048.4, filed on January 10, 2023, entitled "Method and apparatus for determining random access resources and storage medium". Technical Field

[0002] This disclosure relates to the field of communications, and in particular to methods, apparatus, and storage media for determining random access resources. Background Technology

[0003] Currently, terminals select random access resource partitions for the random access procedure on a per-feature basis. However, for random access procedures triggered by Network Slice AS Groups (NSAGs), since network devices configure random access resources on a per-NSAG basis, under the existing process, one or more NSAGs ultimately determined by the terminal may correspond to multiple random access resource partitions, and the terminal cannot determine which random access resource partition to use for random access. Therefore, the NSAG-triggered random access procedure needs optimization. Summary of the Invention

[0055] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the invention as detailed in the appended claims.

[0056] The terminology used in this disclosure is for the purpose of describing particular embodiments only and is not intended to be limiting of the disclosure. The singular forms “a,” “the,” and “the” as used in this disclosure and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used herein refers to and includes any or all possible combinations of at least one associated listed item.

[0057] It should be understood that although the terms first, second, third, etc., may be used in this disclosure to describe various information, such information should not be limited to these terms. These terms are used only to distinguish information of the same type from one another. For example, without departing from the scope of this disclosure, first information may also be referred to as second information, and similarly, second information may also be referred to as first information. Depending on the context, the word "if" as used herein may be interpreted as "when," "when," or "in response to determination."

[0058] In Release 17 (R17), to enable network devices to identify R17 features early and provide terminals with the corresponding random access resource configurations, network devices can configure corresponding random access resource partitions for multiple features and / or at least one combination of features of a terminal. These features include, but are not limited to, at least one of the following: Small Data Transmission (SDT); Coverage Enhancement (CE); Reduced Capability (REDCAP); and Radio Network Slicing.

[0059] The terminal initiates random access based on the resources corresponding to the random access resource partition configured by the network device. The network device identifies the characteristics and / or combinations of characteristics of the terminal by recognizing the features and / or combinations of characteristics corresponding to the resources selected by the terminal.

[0060] In one example, the terminal first determines the feature and / or combination of features that triggered the random access, and based on the random access resource partition configuration of the network device, determines whether there are candidate random access resource partitions corresponding to the feature and / or combination of features that triggered the random access. If there are no candidate random access resource partitions, the terminal selects a legacy random access resource. A legacy random access resource refers to a random access resource that is not associated with any feature and / or combination of features. If there is a candidate random access resource partition, the terminal selects the resources included in that candidate random access resource partition. If there are multiple candidate random access resource partitions, the terminal can select a random access resource partition based on feature priority. Feature priority can be configured by the network device.

[0061] Due to limitations in random access resources and actual network deployment, network devices may not provide corresponding random access resource partitions for all feature combinations; that is, some feature combinations may not find corresponding random access resource partitions. In this case, the terminal's Media Access Control (MAC) layer performs random access resource partition selection based on the feature priorities configured by the network device, prioritizing the ability of high-priority features to find corresponding random access resource partitions. In other words, the random access resource partition ultimately selected by the terminal may not support all features and / or feature combinations applicable to this random access process. Furthermore, for feature RAN slicing, network devices configure random access resource partitions at a per-NSAG granularity.

[0062] In Release 17 (R17), to avoid the security and signaling load issues caused by Single Network Slice Selection Assistance information (S-NSSAI) broadcast in broadcast signaling, the Network Slice Access Layer Group (NSAG) mechanism was introduced. For ease of description, this disclosure will refer to the Network Slice Access Layer Group as the Network Slice Group.

[0063] From the network equipment perspective, the base station can provide the terminal with the NSAG and NSAG configuration supported by the base station, enabling the terminal to perform cell reselection based on network slicing and to enhance random access resource configuration. Simultaneously, core network equipment can send NSAG information and S-NSSAI to the terminal via Non-Access Stratum (NAS) signaling, allowing the terminal to map the required S-NSSAI to the NSAG and perform cell reselection and random access procedures based on the NSAG configuration. The NSAG information includes, but is not limited to, the mapping relationship between S-NSSAI and NSAG, NSAG priority, and corresponding regional information, including but not limited to Tracking Area Identity (TAI).

[0064] From the terminal side, the terminal receives S-NSSAI(S) and NSAG information sent by the core network equipment through NAS signaling. The terminal NAS layer passes the information of one or more network slices (and / or the information of network slice packets) to the access layer (AS) for the AS to determine the NSAG identifier for cell selection and reselection.

[0065] In one example, during a network slice-triggered random access procedure, the terminal's Radio Resource Control (RRC) layer determines the NSAGs associated with the triggering S-NSSAI and broadcast in system messages (e.g., System Information Block 1) based on the mapping relationship between S-NSSAI and NSAGs, as well as NSAG priorities, provided by higher layers. It then selects the NSAG with the highest priority for this random access procedure. However, since the Authentication Management Function (AMF) may configure NSAGs of equal priority, there may be multiple highest-priority NSAGs. Therefore, the terminal's RRC layer may ultimately determine one or more NSAGs for the random access procedure.

[0066] Currently, when a terminal determines candidate random access resource partitions and ultimately selects the random access resource partition for the random access procedure, the process is performed at the per-feature level. However, for random access procedures triggered by network slice AS groups (NSAGs), the corresponding random access resource configuration is determined at the per-NSAG level.

[0067] Therefore, regardless of whether the terminal RRC layer selects and provides the MAC layer with one or more NSAGs with the highest NSAG priority, for the random access procedure triggered by NSAG, there may be multiple random access resource partitions that are ultimately determined for the random access procedure. Obviously, the process of determining random access resources needs to be optimized.

[0068] For example, suppose the RRC layer of the terminal determines and provides the NSAG to the MAC layer as NSAG1, and the features that trigger the random access procedure include NSAG#1 and CE.

[0069] Network devices broadcast random access resource partition configurations via system messages, such as System Information Block 1 (SIB1), including: Randomly access resource partition #1 and associate it with NSAG #1; Randomly access resource partition #2 and associate it with NSAG#1 and NSAG#2.

[0070] The terminal determines candidate random access resource partitions, including random access resource partition #1 and random access resource partition #2, based on the characteristics that trigger the random access procedure (NSAG#1 and CE). Then, the terminal further determines the target random access resource partition for the random access procedure based on the priority of these characteristics. Assuming NSAG#1 has a higher priority, but because both random access resource partition #1 and random access resource partition #2 are associated with NSAG#1, the terminal considers both random access resource partition #1 and random access resource partition #2 to be potential target random access resource partitions, making it impossible to determine a unique target random access resource partition based solely on the priority of these characteristics.

[0071] For another example, suppose the RRC layer determines and provides the NSAGs to the MAC layer as NSAG#1 and NSAG#2, and the features that trigger random access include NSAG#1 and NSAG#2. The network device's random access resource partition configuration, broadcast via system messages such as SIB1, includes: Randomly access resource partition #1 and associate it with NSAG #1; Randomly access resource partition #2 and associate it with NSAG #2.

[0072] The terminal determines candidate random access resource partitions, including random access resource partition #1 and random access resource partition #2, based on the characteristics that trigger the random access procedure (NSAG#1 and NSAG#2). Assuming that NSAG#1 and NSAG#2 have the same NSAG priority, the terminal cannot further select a unique target random access resource partition for this random access procedure based on the characteristic priority.

[0073] To address the aforementioned technical problems, this disclosure provides the following methods, apparatus, and storage media for determining random access resources. For example... Figure 1 The diagram shown is a schematic representation of a network architecture applicable to the scheme disclosed herein. The network in this disclosure can be a 4G network, a 5G network, a 6G network, or a future communication network, etc., and this disclosure does not limit it. The network architecture includes: Terminal 101 ( Figure 1 (Including 101-1, 101-2, 101-3, etc.), terminal 101 can be a smartphone, desktop computer, laptop computer, tablet computer, etc., and this disclosure does not limit it.

[0074] The first network device 102 includes, but is not limited to, base stations and access network equipment. The base station can be a 4G base station, a 5G base station, or a future 6G base station, and the access network equipment can be a 4G access network equipment, a 5G access network equipment, or a future 6G access network equipment, etc. This disclosure does not limit the scope of these devices. Optionally, the first network device 102 may also include core network equipment, such as an AMF (Active Network Frame).

[0075] The second network device 103 includes, but is not limited to, base stations and access network equipment. The base station can be a 4G base station, a 5G base station, or a future 6G base station, and the access network equipment can be a 4G access network equipment, a 5G access network equipment, or a future 6G access network equipment, etc. This disclosure does not limit the scope of these devices. Optionally, the second network device 103 may also include core network equipment, such as an AMF (Active Network Frame).

[0076] In the embodiments of this disclosure, the first network device 102 and the second network device 103 can be network devices of the same type or different types. For example, both can be base stations, or both can be core network devices, or one can be a base station and the other can be a core network device. Optionally, when the first network device 102 and the second network device 103 are network devices of the same type, they can be the same device or different devices, and this disclosure does not limit either of them.

[0077] In some alternative embodiments, terminal 101 may determine a first random access resource partition.

[0078] The first random access resource partition refers to the candidate random access resource partition for random access.

[0079] In one example, terminal 101 may identify the random access resource partition associated with all first NSAGs as the first random access resource partition.

[0080] The first NSAG includes one or more NSAGs that are determined by the RRC layer of the terminal and provided to the MAC layer.

[0081] Furthermore, after determining the first random access resource partition, the terminal can determine the target random access resource partition according to relevant technologies. Methods for determining the target random access resource partition include, but are not limited to, directly determining the first random access resource partition as the target random access resource partition.

[0082] In this disclosure, the target random access resource partition is the random access resource partition used for this random access. It is understood that the terminal determines the configuration for initiating random access based on the target random access resource partition, including but not limited to using resources in the target random access resource partition to initiate random access.

[0083] In another example, terminal 101 may determine a first random access resource partition based on the random access resource partition configuration information sent by the first network device 102.

[0084] It should be noted that the random access resource partition configuration information can satisfy at least one of the following: a random access resource partition is associated with a single NSAG; a random access resource partition is associated with multiple NSAGs; wherein, multiple NSAGs are not determined and submitted to the MAC layer by the RRC layer at the same time; each NSAG is associated with a random access resource partition.

[0085] The configuration information for random access resource partitions will be introduced in subsequent embodiments and will not be discussed here.

[0086] Furthermore, after determining the first random access resource partition, the terminal can determine the target random access resource partition according to relevant technologies. Methods for determining the target random access resource partition include, but are not limited to, directly determining the first random access resource partition as the target random access resource partition.

[0087] In another example, the terminal can determine the first random access resource partition according to the above technical solution. For example, assuming the RRC layer determines and provides NSAGs as NSAG#1 and NSAG#2, the characteristics triggering random access include NSAG#1 and NSAG#2. The network device configures the random access resource partition through system messages, such as SIB1 broadcasts, including: Randomly access resource partition #1 and associate it with NSAG #1; Randomly access resource partition #2 and associate it with NSAG #2.

[0088] Assuming that NSAG#1 and NSAG#2 have the same NSAG priority, terminal 101 determines that the first random access resource partition includes random access resource partition #1 and random access resource partition #2.

[0089] At this time, terminal 101 determines multiple first random access resource partitions. Terminal 101 can determine a target random access resource partition from the multiple first random access resource partitions for this random access based on terminal policies, indication information sent by the first network device, and / or protocol agreements.

[0090] Accordingly, the target random access resource partition satisfies at least one of the following: the number of associated NSAGs is the largest; only the first NSAG is associated; wherein the first NSAG includes one or more NSAGs determined by the RRC layer and submitted to the MAC layer; and the priority of the associated NSAGs meets the preset conditions.

[0091] The terminal can determine the priority according to the indication information sent by the first network device. The indication information is used to determine the target random access resource partition among multiple first random access resource partitions.

[0092] Optionally, the priority can be configured for the terminal by a first network device through indication information. The first network device includes, but is not limited to, base stations, core network devices, etc.

[0093] For example, the priority can be the NSAG priority in the existing mechanism, configured by network devices such as base stations and core network devices, and may include NSAG priorities.

[0094] For example, the priority may also be an additional priority configured by the first network device for NSAG, which is different from the NSAG priority in the existing mechanism described above. The additional priority may or may not include the NSAG priority, and this disclosure does not limit it.

[0095] For example, the priority can also be the priority of the random access resource partition.

[0096] This disclosure does not specify any priority.

[0097] In some alternative embodiments, the first network device 102 may send first information to the terminal 101. The first information is used by the terminal 101 to determine a first random access resource partition. Here, the number of first random access resource partitions is one. Alternatively, the first information is used by the terminal 101 to determine a target random access resource partition among multiple first random access resource partitions for this random access.

[0098] In one example, the first information may include random access resource partition configuration information, which may satisfy at least one of the following: a random access resource partition is associated with a single NSAG; a random access resource partition is associated with multiple NSAGs; wherein multiple NSAGs are not determined and submitted to the MAC layer by the RRC layer at the same time; and each NSAG is associated with a random access resource partition.

[0099] Accordingly, the first information can be used by the terminal to determine a first random access resource partition.

[0100] In another example, the first information may include indication information for the terminal to determine a target random access resource partition among a plurality of first random access resource partitions for this random access.

[0101] In some alternative embodiments, the second network device 103 may send network slice information to the first network device 102, so that the first network device 102 can determine the multiple NSAGs associated with a random access resource partition, wherein the multiple NSAGs are not determined and submitted to the MAC layer by the terminal's RRC layer at the same time.

[0102] The network slice information includes at least one of the following: the mapping relationship between individual network slice selection assistance information S-NSSAI and NSAG; NSAG priority; and the area information corresponding to the mapping relationship, wherein the area information includes at least the tracking area identifier (TAI).

[0103] The network slice includes at least one of the following: a network slice that the terminal is allowed to access NSAG; a network slice that cannot be registered and used simultaneously.

[0104] In the above embodiments, during the random access process triggered by network slicing, the terminal can uniquely identify a target random access resource partition for this random access, thereby improving the reliability of the random access process applied to network slicing.

[0105] In this embodiment of the disclosure, the target random access resource partition determined by the terminal for random access can satisfy at least one of the following: Configuration requirements corresponding to as many features as possible; Provide as many dedicated configurations as possible for a particular feature.

[0106] For example, if the target random access resource partition (RRP) satisfies the configuration requirements corresponding to as many features as possible, the target RRP may involve network slicing, and the features can be implemented at the per NSAG granularity. For instance, the target RRP could be the RRP with the most associated NSAGs.

[0107] For example, if the target random access resource partition satisfies the requirement of providing as much dedicated configuration as possible for a certain feature, for instance, the target random access resource partition may be a random access resource partition that is only associated with a first NSAG, wherein the first NSAG includes one or more NSAGs determined by the terminal's RRC layer and submitted to the MAC layer.

[0108] For example, a first network device configures a specific configuration for one or more features, and the target random access resource partition is associated with the one or more features with the specific configuration. For network slices, features can be configured at the per NSAG granularity, that is, the first network device configures a specific configuration for one or more NSAGs, and the target random access resource partition is associated with the one or more NSAGs with the specific configuration.

[0109] For example, the target random access resource partition can also be a random access resource partition whose priority in the associated NSAG meets preset conditions.

[0110] Optionally, the priority can be determined by indication information sent by the first network device, which is used by the terminal to determine the target random access resource partition from multiple first random access resource partitions.

[0111] Priority can be configured for the terminal by the first network device through indication information. The first network device includes, but is not limited to, base stations, core network devices, etc.

[0112] For example, the priority can be the NSAG priority in the existing mechanism, configured by network devices such as base stations and core network devices, and may include NSAG priorities.

[0113] For example, the priority may also be an additional priority configured by the first network device for NSAG, which is different from the NSAG priority in the existing mechanism described above. The additional priority may or may not include the NSAG priority, and this disclosure does not limit it.

[0114] For example, the priority can also be the priority of the random access resource partition.

[0115] Any method by which a terminal determines a target random access resource partition that meets at least one or more of the above conditions should fall within the protection scope of this disclosure. The following section will first introduce the method for determining random access resources provided in this disclosure from the perspective of the terminal.

[0116] This disclosure provides a method for determining random access resources, referring to... Figure 2 As shown, Figure 2 This is a flowchart illustrating a method for determining random access resources according to an embodiment, which can be executed by a terminal. The method may include the following steps: In step 201, the first random access resource partition is determined.

[0117] In this embodiment of the disclosure, the first random access resource partition can be a candidate random access resource, specifically a random access resource partition corresponding to the characteristics and / or combinations of characteristics of the current random access procedure. The number of first random access resource partitions can be one or more.

[0118] It should be noted that, for the terminal, the features and / or combinations of features visible at the MAC layer refer to the features and / or combinations of features applicable to random access, while the features and / or combinations of features visible at the RRC layer refer to the features and / or combinations of features that trigger random access.

[0119] For example, the terminal determines the first random access resource partition based on the random access resource partition configuration issued by the first network device. The first network device includes, but is not limited to, base stations and access network devices. The base station can be a 4G base station, a 5G base station, or a future 6G base station, and the access network device can be a 4G access network device, a 5G access network device, or a future 6G access network device, etc., and this disclosure does not limit this. Optionally, the first network device 102 may also include core network equipment, such as AMF, etc.

[0120] In this embodiment of the disclosure, the terminal may determine the first random access resource using any of the following methods: Method 1: The terminal determines the random access resource partition associated with all first NSAGs as the first random access resource partition.

[0121] In the embodiments of this disclosure, the first NSAG refers to the NSAG determined by the RRC layer of the terminal and provided to the MAC layer for random access resource selection. The number of first NSAGs can be one or more, and this disclosure does not limit this number.

[0122] In mode one, the terminal of the first network device can determine a first random access resource partition.

[0123] For example, assuming the first NSAG includes NSAG#1 and NSAG#2, and NSAG#1 and NSAG#2 have the same NSAG priority, the first network device broadcasts a random access resource partition configuration via system messages, such as SIB1, including: Randomly access resource partition #1 and associate it with NSAG #1; Randomly access resource partition #2 and associate it with NSAG#1 and NSAG#2.

[0124] According to Method 1 provided in this application, the number of first NSAGs associated with random access resource partition #1 and random access resource partition #2 are 1 and 2 respectively, and the terminal determines the random access resource partition #2 with more associated first NSAGs as the first random access resource partition.

[0125] It should be noted that, assuming the number of first NSAGs is 3, the first network device can associate the random access resource partition configuration with at most 2 of the first NSAGs through system messages, such as SIB1 broadcast. The terminal can choose not to determine the first random access resource partition based on the random access resource partition that would be associated with all first NSAGs. Optionally, the terminal can determine the first random access resource partition according to the existing technology, and then determine a target random access resource partition for this random access through subsequent step 202.

[0126] Alternatively, step 201 may include the following steps: In step 201-1, the random access resource partition associated with the first NSAG is designated as the second random access resource partition.

[0127] In this step, the terminal identifies all random access resource partitions associated with at least one of the first NSAGs as the second random access resource partitions.

[0128] In step 201-2, the random access resource partition with the most associated NSAGs in the first NSAG is determined from the second random access resource partition as the first random access resource partition.

[0129] For example, assuming the first NSAG includes NSAG#1, NSAG#2, and NSAG#3, and NSAG#1 and NSAG#2 have the same NSAG priority, the first network device broadcasts a random access resource partition configuration via system messages, such as SIB1, including: Randomly access resource partition #1 and associate it with NSAG #1; Randomly access resource partition #2 and associate it with NSAG#1 and NSAG#2.

[0130] The terminal determines random access resource partition #1 and random access resource partition #2 as the second random access resource partitions. The terminal determines the random access resource partition with the most associated first NSAGs in the second random access resource partitions as random access resource partition #2, and the terminal determines it as the first random access resource partition.

[0131] Method 2: The terminal determines the first random access resource partition based on the random access resource partition configuration information sent by the first network device.

[0132] In Method 2, the terminal can determine a first random access resource partition.

[0133] In one example, the random access resource partition configuration information is associated with a single NSAG. That is, each random access resource partition configured in the random access resource partition configuration information is associated with a single NSAG.

[0134] For example, random access resource partition #1 is associated with NSAG #1, random access resource partition #2 is associated with NSAG #2, and so on.

[0135] In another example, random access resource partition configuration information is associated with multiple NSAGs.

[0136] Among them, multiple NSAGs refer to multiple NSAGs that are not determined and submitted to the MAC layer by the terminal's RRC layer at the same time.

[0137] In this embodiment, the second network device can provide network slicing information to the first network device. The network slicing information is used by the first network device to determine the multiple NSAGs associated with a random access resource partition. The second network device includes, but is not limited to, base stations and access network devices. The base station can be a 4G base station, a 5G base station, or a future 6G base station, and the access network device can be a 4G access network device, a 5G access network device, or a future 6G access network device, etc. This disclosure does not limit the specific types of devices. Optionally, the second network device may further include core network devices.

[0138] In one example, the first network device and the second network device can be of the same or different types.

[0139] For example, the first network device can be a base station, and the second network device can also be a base station. The two base stations can be the same or different, and this disclosure does not limit this.

[0140] For example, the first network device can be a core network device, and the second network device can be a base station.

[0141] For example, the first network device can be a base station, and the second network device can be a core network device.

[0142] For example, the first network device can be a core network device, and the second network device can be a core network device. These two core network devices can be the same type or different types of core network devices, such as both being AMF, or one being an AMF and the other being a core network function device different from AMF. This disclosure does not limit either of these.

[0143] Optionally, the network slice information includes, but is not limited to, at least one of the following: the mapping relationship between S-NSSAI and NSAG; NSAG priority; and the region information corresponding to the mapping relationship, wherein the region information includes at least TAI.

[0144] The NSAG priority here can be the NSAG priority in the existing mechanism, configured by network devices such as base stations and core network devices, and may include NSAG priorities.

[0145] Network slices include, but are not limited to, at least one of the following: network slices that the terminal is allowed to access via NSAG; and network slices that cannot be registered and used simultaneously. Here, NSAG can be any NSAG, meaning that network slices include network slices that the terminal is allowed to access via any NSAG.

[0146] A network slice that cannot be registered and used simultaneously refers to a network slice that is determined by the first network device within the same time period and that terminals are not allowed to register and use simultaneously.

[0147] For example, random access resource partition #1 is associated with NSAG#1 and NSAG#3, where NSAG#1 and NSAG#3 will not allow terminals to register and use at the same time.

[0148] In another example, the random access resource partition configuration information associates each NSAG with one random access resource partition. It should be noted that this refers to each NSAG being associated with only one random access resource partition.

[0149] For example, if the random access resource partition configuration information includes random access resource partition #1 associated with NSAG #1, then the random access resource partition configuration information will no longer include NSAG #1 or any other random access resource partitions associated with one or more NSAGs. For instance, it will no longer include random access resource partition #2 associated with NSAG #1 and NSAG #2.

[0150] In step 202, a target random access resource partition is determined from the first random access resource partition for this random access.

[0151] In this embodiment of the disclosure, if the number of the first random access resource partitions determined by the terminal according to the above-described method one or method two is 1, the terminal can directly determine the first random access resource partition as the target random access resource partition according to the relevant technology.

[0152] In one example, if the number of first random access resource partitions determined by the terminal according to method one or method two above is multiple, the terminal can further determine the target random access resource partition.

[0153] In this embodiment of the disclosure, the target random access resource partition finally determined by the terminal can satisfy at least one of the following: the number of associated NSAGs is the largest; only the first NSAG is associated, the first NSAG includes the NSAG determined by the Radio Resource Control (RRC) layer and submitted to the Media Access Control (MAC) layer; and the priority of the associated NSAGs meets a preset condition.

[0154] In one example, the terminal identifies the first random access resource partition with the most associated NSAGs among multiple first random access resource partitions as the target random access resource partition.

[0155] In another example, among multiple first random access resource partitions, the terminal can identify the first random access resource partition that is only associated with the first NSAG as the target random access resource partition.

[0156] The first NSAG includes one or more NSAGs determined by the RRC layer and provided to the MAC layer.

[0157] In another example, the terminal determines the target random access resource partition from among multiple first random access resource partitions whose priority associated with the NSAG meets a preset condition.

[0158] The preset condition here can be that the priority of the first random access resource partition is higher than that of other first random access resource partitions.

[0159] The priority can be determined by the indication information sent by the first network device. The indication information is used to determine the target random access resource partition from multiple first random access resource partitions.

[0160] Priority can be configured for the terminal by the first network device through indication information. The first network device includes, but is not limited to, base stations, core network devices, etc.

[0161] For example, the priority can be the NSAG priority in the existing mechanism, configured by network devices such as base stations and core network devices, and may include NSAG priorities.

[0162] For example, the priority may also be an additional priority configured by the first network device for NSAG, which is different from the NSAG priority in the existing mechanism described above. The additional priority may or may not include the NSAG priority, and this disclosure does not limit it.

[0163] For example, the priority can also be the priority of the random access resource partition.

[0164] In another example, the terminal identifies the first random access resource partition with the most associated NSAGs and only associated with first NSAGs as the target random access resource partition among multiple first random access resource partitions.

[0165] In another example, the terminal determines the first random access resource partition as the target random access resource partition among multiple first random access resource partitions, which is only associated with the first NSAG and whose associated NSAG priority meets the preset conditions.

[0166] In another example, the terminal determines the first random access resource partition as the target random access resource partition among multiple first random access resource partitions, which has the most associated NSAGs, is associated only with the first NSAG, and whose associated NSAG priority meets the preset conditions.

[0167] In one possible implementation, the target random access resource partition can be determined from multiple first random access resource partitions based on the terminal policy.

[0168] The terminal strategy can be a strategy formulated by the terminal based on its own services to determine a target random access resource partition among multiple first random access resource partitions. The specific terminal strategy is not limited in this disclosure.

[0169] For example, the terminal policy can be random selection. Alternatively, the terminal policy can be to select the resource with the most random access points; this disclosure does not limit this.

[0170] In another possible implementation, the target random access resource partition can be determined among multiple first random access resource partitions based on the indication information sent by the first network device.

[0171] In one example, this information can be used to configure priorities for multiple NSAGs.

[0172] For example, the priority can be the NSAG priority in the existing mechanism, configured by network devices such as base stations and core network devices, and may include NSAG priorities.

[0173] For example, the priority may also be an additional priority configured by the first network device for NSAG, which is different from the NSAG priority in the existing mechanism described above. The additional priority may or may not include the NSAG priority, and this disclosure does not limit it.

[0174] For example, the priority can also be the priority of the random access resource partition.

[0175] Based on this indication information, the terminal can select the first random access resource partition that meets the preset priority conditions from multiple first random access resource partitions as the target random access resource partition.

[0176] For example, if the first NSAG is NSAG#1 or NSAG#2, the first network device broadcasts the random access resource partition configuration via system messages, such as SIB1, including: Randomly access resource partition #1 and associate it with NSAG #1; Randomly access resource partition #2 and associate it with NSAG #2.

[0177] The terminal determines that the first random access resource partition includes random access resource partition #1 and random access resource partition #2.

[0178] The first network device sends indication information configuring priorities for NSAG#1 and NSAG#2, where NSAG#1 has a higher priority than NSAG#2. Therefore, the terminal determines random access resource partition #1 as the target random access resource partition.

[0179] In another example, the indication information can be used to instruct the terminal to determine the target random access resource partition based on the number of NSAGs associated with the random access resource partition.

[0180] Then the terminal can determine the first random access resource partition corresponding to the NSAG with the most associated NSAGs among multiple first random access resource partitions as the target random access resource partition.

[0181] For example, if the first NSAG is NSAG#1 or NSAG#2, the first network device broadcasts the random access resource partition configuration via system messages, such as SIB1, including: Randomly access resource partition #1 and associate it with NSAG #1; Randomly access resource partition #2 and associate it with NSAG#1 and NSAG#2.

[0182] The terminal determines that the first random access resource partition includes random access resource partition #1 and random access resource partition #2.

[0183] The terminal receives an indication message sent by the first network device. This indication message can be used to instruct the terminal to determine the target random access resource partition based on the number of NSAGs associated with the random access resource partition. The terminal determines the random access resource partition #2 with the most associated NSAGs as the target random access resource partition.

[0184] In another possible implementation, the target random access resource partition is determined from among multiple first random access resource partitions based on protocol agreements.

[0185] For example, the protocol may stipulate that the terminal determines the target random access resource partition among multiple first random access resource partitions according to the number of associated NSAGs.

[0186] Alternatively, the protocol may stipulate that the terminal determines the target random access resource partition based on the first random access resource partition associated only with the first NSAG.

[0187] Alternatively, the protocol can stipulate that the terminal determines the target random access resource partition from multiple first random access resource partitions according to priority.

[0188] Alternatively, the protocol may stipulate that the terminal will randomly access the target random access resource partition with the smallest or largest index value.

[0189] Alternatively, the terminal may, by way of agreement, randomly select one of multiple first random access resource partitions as the target random access resource partition.

[0190] The above is merely an illustrative example. Other provisions may be agreed upon in the agreement. Any method by which the terminal determines the target random access resource partition in accordance with the agreement shall fall within the protection scope of this disclosure.

[0191] In another possible implementation, the target random access resource partition can be determined from multiple first random access resource partitions based on the terminal policy and the indication information sent by the first network device.

[0192] For example, the terminal determines multiple random access resource partitions that can be used as target random access resource partitions among multiple first random access resource partitions according to the instruction information sent by the first network device, and the terminal can further determine the target random access resource partition according to the terminal policy.

[0193] For example, random access resource partition #1 is associated with NSAG #1; random access resource partition #2 is associated with both NSAG #1 and NSAG #2.

[0194] The first random access resource partition includes random access resource partition #1 and random access resource partition #2. The indication information indicates the priority of the random access resource partition. The terminal determines that random access resource partition #1 and random access resource partition #2 can both be used as the target random access resource partition according to the indication information.

[0195] The terminal can randomly select random access resource partition #2 as the target random access resource partition according to the terminal policy.

[0196] In another possible implementation, the target random access resource partition can be determined from multiple first random access resource partitions based on protocol agreements and terminal policies.

[0197] The implementation method is similar to the above embodiments, and will not be described again here.

[0198] In another possible implementation, the target random access resource partition can be determined from multiple first random access resource partitions based on the protocol agreement and the indication information sent by the first network device.

[0199] For example, the protocol stipulates that the terminal determines the target random access resource partition among multiple first random access resource partitions based on the indication information sent by the first network device.

[0200] In another possible implementation, the target random access resource partition can be determined from multiple first random access resource partitions based on terminal policies, protocol agreements, and indication information sent by the first network device.

[0201] The above is merely an illustrative example. In practical applications, any method by which a terminal uniquely determines the target random access resource partition among multiple first random access resource partitions should fall within the protection scope of this disclosure.

[0202] In the above embodiments, during the random access process triggered by network slicing, the terminal can determine a first random access resource partition, thereby improving the reliability of the random access process applied to network slicing.

[0203] In some alternative embodiments, refer to Figure 3 As shown, Figure 3 This is a flowchart illustrating a method for determining random access resources according to an embodiment, which can be executed by a terminal. The method may include the following steps: In step 301, a target random access resource partition is determined from a plurality of first random access resource partitions for this random access.

[0204] In this embodiment of the disclosure, the terminal may use relevant technologies to determine the first random access resource partition.

[0205] For example, suppose the first NSAG provided by the RRC layer to the MAC layer is NSAG1, and the features that trigger the random access procedure include NSAG#1 and CE.

[0206] Network devices broadcast random access resource partition configurations via system messages, such as System Information Block 1 (SIB1), including: Randomly access resource partition #1 and associate it with NSAG #1; Randomly access resource partition #2 and associate it with NSAG#1 and NSAG#2.

[0207] The terminal determines that the first random access resource partition includes random access resource partition #1 and random access resource partition #2.

[0208] For example, suppose the first NSAG determined and provided to the MAC layer by the RRC layer is NSAG#1 and NSAG#2, and the features triggering random access include NSAG#1 and NSAG#2, and have the same NSAG priority. The random access resource partition configuration broadcast by the network device through system messages, such as SIB1, includes: Randomly access resource partition #1 and associate it with NSAG #1; Randomly access resource partition #2 and associate it with NSAG #2.

[0209] The terminal determines that the first random access resource partition includes random access resource partition #1 and random access resource partition #2.

[0210] When a terminal identifies multiple first random access resource partitions, it can determine the target random access resource partition using the following methods: In this embodiment of the disclosure, the target random access resource partition ultimately determined by the terminal may satisfy at least one of the following: having the most associated NSAGs; associating only the first NSAG, wherein the first NSAG includes one or more NSAGs determined by the Radio Resource Control (RRC) layer and submitted to the Media Access Control (MAC) layer; and the priority of the associated NSAGs meets a preset condition. In one example, the terminal determines the first random access resource partition with the most associated NSAGs as the target random access resource partition among multiple first random access resource partitions.

[0211] In another example, the terminal identifies the first random access resource partition that is only associated with the first NSAG as the target random access resource partition among multiple first random access resource partitions.

[0212] The number of first NSAGs can be one or more, and the first NSAGs include one or more NSAGs determined by the RRC layer and provided to the MAC layer.

[0213] In another example, the terminal determines the target random access resource partition from among multiple first random access resource partitions whose priority associated with the NSAG meets a preset condition.

[0214] The preset condition here can be that the priority of the first random access resource partition is higher than that of other first random access resource partitions.

[0215] The priority can be determined by the indication information sent by the first network device. The indication information is used to determine the target random access resource partition among multiple first random access resource partitions.

[0216] Priority can be configured for the terminal by the first network device through indication information. The first network device includes, but is not limited to, base stations, core network devices, etc.

[0217] For example, the priority can be the NSAG priority in the existing mechanism, configured by network devices such as base stations and core network devices, and may include NSAG priorities.

[0218] For example, the priority may also be an additional priority configured by the first network device for NSAG, which is different from the NSAG priority in the existing mechanism described above. The additional priority may or may not include the NSAG priority, and this disclosure does not limit it.

[0219] For example, the priority can also be the priority of the random access resource partition.

[0220] In another example, the terminal identifies the first random access resource partition with the most associated NSAGs and only associated with first NSAGs as the target random access resource partition among multiple first random access resource partitions.

[0221] In another example, the terminal determines the first random access resource partition as the target random access resource partition among multiple first random access resource partitions, which is only associated with the first NSAG and whose associated NSAG priority meets the preset conditions.

[0222] In another example, the terminal determines the first random access resource partition as the target random access resource partition among multiple first random access resource partitions, which has the most associated NSAGs, is associated only with the first NSAG, and whose associated NSAG priority meets the preset conditions.

[0223] In one possible implementation, the target random access resource partition can be determined from multiple first random access resource partitions based on the terminal policy.

[0224] The terminal strategy can be a strategy formulated by the terminal based on its own services to determine a target random access resource partition among multiple first random access resource partitions. The specific terminal strategy is not limited in this disclosure.

[0225] For example, the terminal policy can be random selection. Alternatively, the terminal policy can be to select the resource with the most random access points; this disclosure does not limit this.

[0226] In another possible implementation, the target random access resource partition can be determined among multiple first random access resource partitions based on the indication information sent by the first network device.

[0227] In one example, this information can be used to configure priorities for multiple NSAGs.

[0228] For example, the priority can be the NSAG priority in the existing mechanism, configured by network devices such as base stations and core network devices, and may include NSAG priorities.

[0229] For example, the priority may also be an additional priority configured by the first network device for NSAG, which is different from the NSAG priority in the existing mechanism described above. The additional priority may or may not include the NSAG priority, and this disclosure does not limit it.

[0230] For example, the priority can also be the priority of the random access resource partition.

[0231] Based on this indication information, the terminal can select the first random access resource partition that meets the preset priority conditions from multiple first random access resource partitions as the target random access resource partition.

[0232] For example, if the first NSAG is NSAG#1 or NSAG#2, the first network device broadcasts the random access resource partition configuration via system messages, such as SIB1, including: Randomly access resource partition #1 and associate it with NSAG #1; Randomly access resource partition #2 and associate it with NSAG #2.

[0233] The terminal determines that the first random access resource partition includes random access resource partition #1 and random access resource partition #2.

[0234] The first network device sends indication information configuring priorities for NSAG#1 and NSAG#2, where NSAG#1 has a higher priority than NSAG#2. Therefore, the terminal determines random access resource partition #1 as the target random access resource partition.

[0235] In another example, the indication information can be used to instruct the terminal to determine the target random access resource partition based on the number of NSAGs associated with the random access resource partition.

[0236] Then the terminal can determine the first random access resource partition corresponding to the NSAG with the most associated NSAGs among multiple first random access resource partitions as the target random access resource partition.

[0237] For example, if the first NSAG is NSAG#1 or NSAG#2, the first network device broadcasts the random access resource partition configuration via system messages, such as SIB1, including: Randomly access resource partition #1 and associate it with NSAG #1; Randomly access resource partition #2 and associate it with NSAG#1 and NSAG#2.

[0238] The terminal determines that the first random access resource partition includes random access resource partition #1 and random access resource partition #2.

[0239] The terminal receives an indication message sent by the first network device. This indication message can be used to instruct the terminal to determine the target random access resource partition based on the number of NSAGs associated with the random access resource partition. The terminal determines the random access resource partition #2 with the most associated NSAGs as the target random access resource partition.

[0240] In another possible implementation, the target random access resource partition is determined from among multiple first random access resource partitions based on protocol agreements.

[0241] For example, the protocol may stipulate that the terminal determines the target random access resource partition among multiple first random access resource partitions according to the number of associated NSAGs.

[0242] Alternatively, the protocol may stipulate that the terminal determines the target random access resource partition based on the first random access resource partition associated only with the first NSAG.

[0243] Alternatively, the protocol can stipulate that the terminal determines the target random access resource partition from multiple first random access resource partitions according to priority.

[0244] Alternatively, the protocol may stipulate that the terminal will randomly access the target random access resource partition with the smallest or largest index value.

[0245] Alternatively, the terminal may, by way of agreement, randomly select one of multiple first random access resource partitions as the target random access resource partition.

[0246] The above is merely an illustrative example. Other provisions may be agreed upon in the agreement. Any method by which the terminal determines the target random access resource partition in accordance with the agreement shall fall within the protection scope of this disclosure.

[0247] In another possible implementation, the target random access resource partition can be determined from multiple first random access resource partitions based on the terminal policy and the indication information sent by the first network device.

[0248] For example, the terminal determines multiple random access resource partitions that can be used as target random access resource partitions among multiple first random access resource partitions according to the instruction information sent by the first network device, and the terminal can further determine the target random access resource partition according to the terminal policy.

[0249] For example, random access resource partition #1 is associated with NSAG #1; random access resource partition #2 is associated with both NSAG #1 and NSAG #2.

[0250] The first random access resource partition includes random access resource partition #1 and random access resource partition #2. The indication information indicates the priority of the random access resource partition. The terminal determines that random access resource partition #1 and random access resource partition #2 can both be used as the target random access resource partition according to the indication information.

[0251] The terminal can randomly select random access resource partition #2 as the target random access resource partition according to the terminal policy.

[0252] In another possible implementation, the target random access resource partition can be determined from multiple first random access resource partitions based on protocol agreements and terminal policies.

[0253] The implementation method is similar to the above embodiments, and will not be described again here.

[0254] In another possible implementation, the target random access resource partition can be determined from multiple first random access resource partitions based on the protocol agreement and the indication information sent by the first network device.

[0255] For example, the protocol stipulates that the terminal determines the target random access resource partition among multiple first random access resource partitions based on the indication information sent by the first network device.

[0256] In another possible implementation, the target random access resource partition can be determined from multiple first random access resource partitions based on terminal policies, protocol agreements, and indication information sent by the first network device.

[0257] The above is merely an illustrative example. In practical applications, any method by which a terminal uniquely determines the target random access resource partition among multiple first random access resource partitions should fall within the protection scope of this disclosure.

[0258] In the above embodiments, the terminal can determine a target random access resource partition suitable for random access from multiple first random access resource partitions, thereby improving the reliability of the random access process applied to network slicing triggers.

[0259] The following section will introduce the method for determining random access resources provided in this disclosure from the perspective of the first network device.

[0260] This disclosure provides a method for determining random access resources, referring to... Figure 4A As shown, Figure 4AThis is a flowchart illustrating a method for determining random access resources according to an embodiment. It can be executed by a first network device, including but not limited to a base station and access network equipment. The base station can be a 4G base station, a 5G base station, or a future 6G base station, and the access network equipment can be a 4G access network equipment, a 5G access network equipment, or a future 6G access network equipment, etc. This disclosure does not limit the scope of the method. Optionally, the first network device may further include core network equipment, etc. The method may include the following steps: In step 401, the first information is sent to the terminal.

[0261] In one possible implementation, the first information can be used by the terminal to determine a first random access resource partition.

[0262] The first information may include random access resource partition configuration information, which is used by the terminal to determine the first random access resource partition.

[0263] In one example, the random access resource partition configuration information is associated with a single NSAG. That is, each random access resource partition configured in the random access resource partition configuration information is associated with a single NSAG.

[0264] In another example, random access resource partition configuration information is associated with multiple NSAGs.

[0265] In this case, multiple NSAGs will not be determined and submitted to the MAC layer by the terminal's RRC layer at the same time.

[0266] In this embodiment of the disclosure, the first network device can receive network slice information sent by the second network device, and then determine the multiple NSAGs that are not simultaneously included in the first NSAG according to the network slice information.

[0267] Network slicing information is used by the first network device to identify multiple NSAGs that are not simultaneously included in the first NSAG.

[0268] The second network equipment includes, but is not limited to, base stations and access network equipment. The base station can be a 4G base station, a 5G base station, or a future 6G base station, and the access network equipment can be a 4G access network equipment, a 5G access network equipment, or a future 6G access network equipment, etc. This disclosure does not impose any limitations on this. Optionally, the second network equipment may also include core network equipment.

[0269] In one example, the first network device and the second network device can be of the same or different types.

[0270] For example, the first network device can be a base station, and the second network device can also be a base station. The two base stations can be the same or different, and this disclosure does not limit this.

[0271] For example, the first network device can be a core network device, and the second network device can be a base station.

[0272] For example, the first network device can be a base station, and the second network device can be a core network device.

[0273] For example, the first network device can be a core network device, and the second network device can be a core network device. These two core network devices can be the same type or different types of core network devices, and this disclosure does not limit either of them.

[0274] Furthermore, when the first network device and the second network device are of the same type, they can be the same device or different devices. When they are the same device, for example, the network slice information can be sent from the RRC layer of the network device to the MAC layer.

[0275] Optionally, the network slice information includes, but is not limited to, at least one of the following: the mapping relationship between S-NSSAI and NSAG; NSAG priority; and the region information corresponding to the mapping relationship, wherein the region information includes at least TAI.

[0276] Network slices include, but are not limited to, at least one of the following: network slices that the terminal is allowed to access via NSAG; and network slices that cannot be registered and used simultaneously. Here, NSAG can be any NSAG, meaning that network slices include network slices that the terminal is allowed to access via any NSAG.

[0277] A network slice that cannot be registered and used simultaneously refers to a network slice that is determined by the first network device within the same time period and that terminals are not allowed to register and use simultaneously.

[0278] In another example, in the random access resource partition configuration information, each NSAG is associated with only one random access resource partition.

[0279] The method by which the terminal side determines the first random access resource partition based on the random access partition configuration information has already been introduced on the terminal side. For details, please refer to the second method for determining the first random access resource partition on the terminal side, which will not be repeated here.

[0280] If the terminal determines that the number of first random access resource partitions is 1, the terminal can directly determine the first random access resource partition as the target random access resource partition in accordance with relevant technologies.

[0281] If the terminal determines multiple first random access resource partitions, the terminal can further determine the target random access resource partition from among the multiple first random access resource partitions. The determination method is similar to step 202 and will not be repeated here.

[0282] In another possible implementation, the first information may include indication information for the terminal to determine the target random access resource partition among a plurality of first random access resource partitions.

[0283] In one example, this indication information can be used to indicate priority for multiple NSAGs.

[0284] For example, the priority can be the NSAG priority in the existing mechanism, configured by network devices such as base stations and core network devices, and may include NSAG priorities.

[0285] For example, the priority may also be an additional priority configured by the first network device for NSAG, which is different from the NSAG priority in the existing mechanism described above. The additional priority may or may not include the NSAG priority, and this disclosure does not limit it.

[0286] For example, the priority can also be the priority of the random access resource partition.

[0287] Based on the indication information sent by the first network device, the terminal can select the first random access resource partition that meets the preset priority conditions from multiple first random access resource partitions as the target random access resource partition.

[0288] The preset condition here can be that the priority of the first random access resource partition is higher than that of other first random access resource partitions.

[0289] In another example, the indication information can be used to instruct the terminal to determine the target random access resource partition based on the number of NSAGs associated with the random access resource partition.

[0290] The terminal can determine a target random access resource partition among multiple first random access resource partitions based on this indication information.

[0291] Alternatively, the terminal can determine the target random access resource partition by combining the protocol agreement and the terminal policy. The specific method is similar to the method in step 301 above where the terminal determines the target random access resource partition from multiple first random access resource partitions, and will not be repeated here.

[0292] In the above embodiments, the first network device can send first information to the terminal, which is used by the terminal to determine a first random access resource partition or to determine a target random access resource partition suitable for random access among multiple first random access resource partitions. In the random access process triggered by network slicing, the terminal can uniquely determine a target random access resource partition suitable for random access, thereby improving the reliability of the random access process applied to network slicing triggering.

[0293] This disclosure provides a method for determining random access resources, referring to... Figure 4B As shown, Figure 4B This is a flowchart illustrating a method for determining random access resources according to an embodiment. It can be executed by a second network device, including but not limited to a base station and access network equipment. The base station can be a 4G base station, a 5G base station, or a future 6G base station, and the access network equipment can be a 4G access network equipment, a 5G access network equipment, or a future 6G access network equipment, etc. This disclosure does not limit the scope of the method. Optionally, the second network device may further include core network equipment, etc. The method may include the following steps: In step 401', network slice information is sent to the first network device.

[0294] Optionally, the network slice information includes, but is not limited to, at least one of the following: the mapping relationship between S-NSSAI and NSAG; NSAG priority; and the region information corresponding to the mapping relationship, wherein the region information includes at least TAI.

[0295] Network slices include, but are not limited to, at least one of the following: network slices that the terminal is allowed to access via NSAG; and network slices that cannot be registered and used simultaneously. Here, NSAG can be any NSAG, meaning that network slices include network slices that the terminal is allowed to access via any NSAG.

[0296] A network slice that cannot be registered and used simultaneously refers to a network slice that is determined by the first network device within the same time period and that terminals are not allowed to register and use simultaneously.

[0297] The first network device can determine multiple NSAGs associated with a random access resource partition based on network slice information.

[0298] Among them, "not many NSAGs" refers to multiple NSAGs that are not determined and submitted to the MAC layer by the terminal's RRC layer at the same time.

[0299] In the above embodiments, the second network device can provide network slicing information to the first network device, so that the first network device can identify multiple NSAGs associated with a random access resource partition, and then configure random access resource partition configuration information for the terminal. This approach is simple to implement and highly available.

[0300] In some alternative embodiments, refer to Figure 5 As shown, Figure 5 This is a flowchart illustrating a method for determining random access resources according to an embodiment, applicable to... Figure 1 In the system shown, this method can be executed by terminal 101, including: In step 501, terminal 101 determines the random access resource partition associated with all first NSAGs as the first random access resource partition.

[0301] In this embodiment, the terminal can determine the random access resource partition associated with all first NSAGs as the first random access resource partition based on the random access resource configuration information sent by the first network device. This embodiment does not limit the specific configuration content of the random access resource partition configuration information sent by the first network device.

[0302] The first NSAG includes one or more NSAGs determined by the Radio Resource Control (RRC) layer and submitted to the Media Access Control (MAC) layer.

[0303] If the number of the first random access resource partitions is 1, the terminal can directly determine the first random access resource partition as the target random access resource partition according to relevant technologies.

[0304] If there are multiple first random access resource partitions, the terminal can continue to determine a target random access resource partition according to step 202 above.

[0305] It should be noted that the terminal can also be operated in accordance with steps 201-1 to 201-2 above ( Figure 5 (Not shown in the diagram) First, the random access resource partition associated with the first NSAG is determined as the second random access resource partition. Then, from the second random access resource partition, the random access resource partition with the largest number of NSAGs associated with the first NSAG is determined as the first random access resource partition. This disclosure does not limit this.

[0306] In the above embodiments, during the random access process triggered by network slicing, the terminal can determine a first random access resource partition, which improves the reliability of the random access process applied to network slicing.

[0307] In some alternative embodiments, refer to Figure 6 As shown, Figure 6 This is a flowchart illustrating a method for determining random access resources according to an embodiment. This method can be applied to... Figure 1 The system shown includes: In step 600, the second network device 103 sends network slice information to the first network device 102.

[0308] Optionally, the network slice information includes, but is not limited to, at least one of the following: the mapping relationship between S-NSSAI and NSAG; NSAG priority; and the region information corresponding to the mapping relationship, wherein the region information includes at least TAI.

[0309] Network slices include, but are not limited to, at least one of the following: network slices that the terminal is allowed to access via NSAG; and network slices that cannot be registered and used simultaneously. Here, NSAG can be any NSAG, meaning that network slices include network slices that the terminal is allowed to access via any NSAG.

[0310] A network slice that cannot be registered and used simultaneously refers to a network slice that is determined by the first network device within the same time period and that terminals are not allowed to register and use simultaneously.

[0311] The first network device can determine multiple NSAGs that are not simultaneously included in the first NSAG based on network slice information.

[0312] The first NSAG includes one or more NSAGs determined by the terminal's RRC layer and submitted to the MAC layer.

[0313] It should be noted that step 600 is optional. That is, if the random access resource partition configuration information configured by the first network device 102 for the terminal 101 is unrelated to the above-mentioned multiple NSAGs, then step 600 may not be executed.

[0314] In step 601, the first network device 102 sends random access resource partition configuration information to the terminal 101.

[0315] In this embodiment of the disclosure, the random access resource partition configuration information can satisfy at least one of the following: a random access resource partition is associated with a single NSAG; a random access resource partition is associated with multiple NSAGs, and the multiple NSAGs are not determined and submitted to the MAC layer by the terminal's RRC layer at the same time; each NSAG is associated with only one random access resource partition.

[0316] The specific details of the random access resource partition configuration information have been introduced in step 401 and will not be repeated here.

[0317] In step 602, terminal 101 determines the first random access resource partition based on the random access resource partition configuration information.

[0318] Since the random access resource partition configuration information is required to meet at least one of the above conditions, the terminal will determine the first random access resource partition based on the random access resource partition configuration information. The determination method is similar to Method 2 in step 201 above, and will not be described again here.

[0319] If the number of the first random access resource partitions is 1, the terminal can directly determine the first random access resource partition as the target random access resource partition according to relevant technologies.

[0320] If there are multiple first random access resource partitions, the terminal can continue to determine a target random access resource partition according to step 202 above.

[0321] In the above embodiments, the first network device is limited to certain conditions, and the random access resource partition configured by the first network device satisfies these conditions, thereby ensuring that the terminal determines a first random access resource partition and improving the reliability of the random access process triggered by network slicing.

[0322] In some alternative embodiments, refer to Figure 7 As shown, Figure 7 This is a flowchart illustrating a method for determining random access resources according to an embodiment. This method can be applied to... Figure 1 In the system shown, this method can be executed by terminal 101, including: In step 701, terminal 101 determines a target random access resource partition from a plurality of first random access resource partitions for this random access.

[0323] In this embodiment of the disclosure, terminal 101 may determine the first random access resource partition using the methods described above: Method 1, Method 2, or Method 3. If there are multiple first random access resource partitions, further, in one possible implementation, the terminal may determine the target random access resource partition among the multiple first random access resource partitions based on at least one of terminal policies, protocol agreements, and indication information sent by the network.

[0324] The specific determination method is similar to steps 202 or 301 above, and will not be repeated here.

[0325] In one example, the terminal may select one of multiple first random access resource partitions as the target random access resource partition for random access, according to the terminal policy.

[0326] The terminal policy can be selected randomly.

[0327] In one example, the terminal can determine the target random access resource partition based on indication information sent by the first network device among multiple first random access resource partitions.

[0328] Optionally, the indication information is used to instruct the terminal to determine the target random access resource partition based on the number of NSAGs associated with the random access resource partition.

[0329] If there are still multiple NSAGs associated with the first random access resource partition, the terminal can further determine one of them as the target random access resource partition based on the protocol agreement and / or terminal policy.

[0330] For example, a target random access resource partition can be randomly selected according to the terminal policy.

[0331] For example, according to the agreement, the random access resource partition with the smallest index value can be determined as the target random access resource partition.

[0332] For example, according to the agreement and terminal policy, the random access resource partition with the most random access resources among multiple first random access resource partitions can be determined as the target random access resource partition.

[0333] In the above embodiments, during the random access process triggered by network slices, the terminal can determine a target random access resource partition suitable for random access, thereby improving the reliability of the random access process triggered by network slices.
