Description

[Technical Field]

[0001] The present disclosure relates to the field of communications, and in particular to a method and apparatus for determining random access resources, and a storage medium. [Background technology]

[0002] Currently, a terminal selects a random access resource partition for a random access process according to the granularity of each feature. On the other hand, in a random access process triggered based on a network slice access layer group (NSAG), the network device configures random access resources based on the granularity of each NSAG (per NSAG). Therefore, based on the existing process, one or more NSAGs finally 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. As can be seen, the random access process based on NSAG triggering needs to be optimized. Summary of the Invention [Problem to be solved by the invention]

DETAILED DESCRIPTION OF THE INVENTION

[0041] Illustrative embodiments will now be described, examples of which are illustrated in the drawings. When the following description is referred to in the drawings, like numerals in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following illustrative examples do not represent all embodiments consistent with embodiments of the present disclosure. Rather, they are merely examples of apparatus and methods consistent with some embodiments of the present disclosure, as recited in the appended claims.

[0042] The terms used in this disclosure are for the purpose of describing particular embodiments and are not intended to limit the embodiments of the present disclosure. As used in the embodiments of the present disclosure and the appended claims, the singular forms "a," "the," and "the" include the plural forms unless the context clearly dictates otherwise. Furthermore, as used herein, the term "and / or" refers to the inclusion of any and all combinations of one or more of the associated listed items.

[0043] In the embodiments of the present disclosure, terms such as "first," "second," and "third" may be used to describe each piece of information, but these terms are not limited to these terms. These terms are used only to distinguish between pieces of information of the same type. For example, the first piece of information may be referred to as the second piece of information, and similarly, the second piece of information may be referred to as the first piece of information, without departing from the scope of the embodiments of the present disclosure. Depending on the context, for example, "when" as used herein may be interpreted as "when," "during," or "in response to determining."

[0044] Release 17 (R17) enables a network device to quickly identify R17 characteristics to provide a terminal with a random access resource configuration corresponding to the R17 characteristics. For example, the network device can configure a corresponding random access resource partition for a combination of multiple characteristics and / or at least one characteristic of the terminal. The characteristics include, but are not limited to, at least one of Small Data Transmission (SDT), Coverage Enhancement (CE), Reduced Capability (REDCAP), and Wireless Network Slicing (RAN Slicing).

[0045] The terminal initiates random access based on resources corresponding to the random access resource partition configured by the network device, and the network device identifies features and / or feature combinations corresponding to the resources selected by the terminal, thereby realizing early identification of the characteristics and / or feature combinations of the terminal.

[0046] In one example, the terminal first determines a characteristic and / or characteristic combination that triggers the current random access, and then determines whether there is a candidate random access resource partition corresponding to the characteristic and / or characteristic combination that triggers the random access based on the random access resource partition configuration configured by the network device. If there is no candidate random access resource partition, 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 characteristic and / or characteristic combination. If there is a candidate random access resource partition, the terminal selects a resource included in the 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 characteristic priority. Here, the characteristic priority can be configured by the network device.

[0047] Due to limitations on random access resources and actual network configuration, a network device may not provide corresponding random access resource partitions for all characteristic combinations. That is, there are characteristic combinations for which no corresponding random access resource partitions can be found. In this case, the Media Access Control (MAC) layer of the terminal performs random access resource partition selection based on the characteristic priorities configured in the network device, and prioritizes ensuring that characteristics with higher priorities can find corresponding random access resource partitions. That is, the random access resource partition finally selected by the terminal may not necessarily support all characteristics and / or characteristic combinations suitable for the current random access process. Furthermore, in the case of characteristic RAN slicing, the network device configures random access resource partitions according to the granularity of per NSAG.

[0048] In R17, a network slice access stratum group (NSAG) mechanism is introduced to avoid security and signaling load issues caused by single network slice selection assistance information (S-NSSAI) broadcast by broadcast signaling. For ease of explanation, this disclosure will abbreviate the network slice access stratum group as network slice group.

[0049] From the network device perspective, a base station can provide a terminal with NSAGs and NSAG configurations supported by the base station to perform cell reselection based on network slices and enhance random access resource configuration. At the same time, a core network device can map the required S-NSSAI to an NSAG via Non-Access Stratum (NAS) signaling and transmit the NSAG information and S-NSSAI to the terminal to perform cell reselection and random access processes based on the NSAG configuration. The NSAG information includes, but is not limited to, the mapping relationship between the S-NSSAI and the NSAG, the NSAG priority, and area information corresponding to the mapping relationship. The area information includes, but is not limited to, a Tracking Area Identity (TAI).

[0050] From the terminal's perspective, the terminal receives the S-NSSAI(S) and NSAG information sent from the core network device via NAS signaling, and the terminal NAS layer conveys information of one or more network slices (and / or information of network slice groups) to the Access Stratum (AS), which is used by the AS to determine the NSAG identifier for cell selection and reselection.

[0051] In one example, in a random access process triggered based on a network slice, a Radio Resource Control (RRC) layer of a terminal determines an NSAG associated with the S-NSSAI triggering the random access and broadcast in a system message (e.g., system information block 1) based on the S-NSSAI triggering the random access provided from a higher layer, the mapping relationship between the S-NSSAI and the NSAG, and the NSAG priority, and selects the NSAG with the highest NSAG priority for the current random access process. However, since an Authentication Management Function (AMF) may set priority NSAGs, there may be multiple highest priority NSAGs, i.e., there may be one or more NSAGs for the terminal RRC layer to finally determine the NSAG for the random access process.

[0052] Currently, the terminal determines candidate random access resource partitions and ultimately selects random access resource partitions for the random access process according to the granularity of each feature. Meanwhile, in a random access process triggered based on a network slice group (NSAG), the corresponding random access resource configuration is determined based on the granularity of each NSAG.

[0053] Therefore, although the number of NSAGs with the highest NSAG priority that the terminal RRC layer selects and provides to the MAC layer may be one or more, for the random access process triggered by the NSAG, there may be multiple random access resource partitions for ultimately determining the random access process, and obviously, the process of determining the random access resource needs to be optimized.

[0054] For example, it is assumed that the NSAG determined by the RRC layer of the terminal and provided to the MAC layer is NSAG1, and the characteristics that trigger the random access process include NSAG#1 and CE.

[0055] The network device broadcasts the random access resource partition configuration via a system message, for example, System Information Block 1 (SIB1). that random access resource partition #1 is associated with NSAG #1; The random access resource partition #2 is associated with NSAG #1 and NSAG #2.

[0056] The terminal determines that the candidate random access resource partitions include random access resource partition #1 and random access resource partition #2 based on the characteristics (NSAG#1 and CE) that trigger the random access process. Then, the terminal further determines a unique target random access resource partition for the random access process based on the characteristic priority. Assume that NSAG#1 has a high priority. However, since random access resource partition #1 and random access resource partition #2 are both associated with NSAG#1, that is, the terminal considers that any random access resource partition #1 or random access resource partition #2 can both be target random access resource partitions, and is therefore unable to determine a unique target random access resource partition based on the characteristic priority.

[0057] For example, it is assumed that the NSAGs determined and provided by the RRC layer to the MAC layer are NSAG#1 and NSAG#2, and the characteristics that trigger random access include NSAG#1 and NSAG#2. The network device notifies the MAC layer via a system message, for example, that the random access resource partition configuration broadcast by SIB1 is that random access resource partition #1 is associated with NSAG #1; The random access resource partition #2 is associated with NSAG #2.

[0058] The terminal determines that the candidate random access resource partitions include random access resource partition #1 and random access resource partition #2 based on the characteristics (NSAG#1 and NSAG#2) that trigger the random access process. 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 the current random access process based on the characteristic priority.

[0059] To solve the above technical problems, the present disclosure provides the following method and apparatus for determining random access resources, and a storage medium. As shown in Figure 1, it is a schematic diagram of a network architecture diagram applied to the disclosed scheme. The network of the present disclosure may be a 4G network, a 5G network, a 6G network, or a future communication network, etc., and the present disclosure is not limited thereto. The network architecture includes: The terminal 101 (FIG. 1 includes 101-1, 101-2, 101-3, etc.) may be a smartphone, a desktop, a notebook computer, a tablet, etc., and the present disclosure is not limited thereto.

[0060] The first network device 102 includes, but is not limited to, a base station, an access network device, etc. The base station may be a 4G base station, a 5G base station, or a future 6G base station, and the access network device may be a 4G access network device, a 5G access network device, or a future 6G access network device, etc., and the present disclosure is not limited thereto. Optionally, the first network device 102 may also include a core network device such as an AMF.

[0061] The second network device 103 includes, but is not limited to, a base station, an access network device, etc. The base station may be a 4G base station, a 5G base station, or a future 6G base station, and the access network device may be a 4G access network device, a 5G access network device, or a future 6G access network device, etc., and the present disclosure is not limited thereto. Optionally, the second network device 103 may also include a core network device such as an AMF.

[0062] In embodiments of the present disclosure, the first network device 102 and the second network device 103 may be the same type or different types of network devices, for example, all may be base stations, or all may be core network devices, or one may be a base station and the other a core network device. Optionally, if the first network device 102 and the second network device 103 are the same type of network device, they may be the same device or different devices, and the present disclosure is not limited thereto.

[0063] In some alternative embodiments, the terminal 101 may determine the first random access resource partition.

[0064] The first random access resource partition refers to a candidate random access resource partition for random access.

[0065] In one example, the terminal 101 may determine the random access resource partition associated with all the first NSAGs as the first random access resource partition.

[0066] The first NSAG includes one or more NSAGs determined by the RRC layer of the terminal and provided to the MAC layer.

[0067] Furthermore, after determining the first random access resource partition, the terminal can determine a target random access resource partition according to the related art, and the manner of determining the target random access resource partition includes, but is not limited to, directly determining the first random access resource partition as the target random access resource partition.

[0068] In the present disclosure, the target random access resource partition is the random access resource partition for the current random access, and it can be understood that the terminal determines a configuration for initiating random access based on the target random access resource partition, including but not limited to initiating random access using resources in the target random access resource partition.

[0069] In another example, the terminal 101 may determine one first random access resource partition based on the random access resource partition configuration information sent by the first network device 102.

[0070] It needs to be explained that the random access resource partition configuration information can satisfy at least one of the following: one random access resource partition is associated with a single NSAG; one random access resource partition is associated with multiple NSAGs, and the multiple NSAGs are determined by the RRC layer at the same time and are not provided to the MAC layer; and each NSAG is associated with one random access resource partition.

[0071] The random access resource partition configuration information will be described in the following examples, but will not be described here.

[0072] Furthermore, after determining the first random access resource partition, the terminal can determine a target random access resource partition according to the related art, and the manner of determining the target random access resource partition includes, but is not limited to, directly determining the first random access resource partition as the target random access resource partition.

[0073] In another example, the terminal can determine the first random access resource partition according to the above technical solution, for example, assume that the NSAGs determined and provided by the RRC layer are NSAG#1 and NSAG#2, and the characteristics triggering random access include NSAG#1 and NSAG#2. The network device can notify the terminal via a system message, for example, by broadcasting the random access resource partition configuration by SIB1: that random access resource partition #1 is associated with NSAG #1; The random access resource partition #2 is associated with NSAG #2.

[0074] Assume that terminal 101 determines that the first random access resource partition includes random access resource partition #1 and random access resource partition #2, where NSAG#1 and NSAG#2 have the same NSAG priority.

[0075] At this time, the terminal 101 determines a plurality of first random access resource partitions, and the terminal 101 can determine one target random access resource partition for the current random access among the plurality of first random access resource partitions based on the terminal policy and the indication information and / or protocol promise sent by the first network device.

[0076] Correspondingly, the target random access resource partition satisfies at least one of the following: it has the largest number of associated NSAGs; it is associated with only the first NSAG, and the first NSAG includes one or more NSAGs determined by the RRC layer and provided to the MAC layer; and the priority of the associated NSAGs satisfies a predetermined condition.

[0077] The terminal may determine the priority according to indication information sent by the first network device, and the indication information is used to determine a target random access resource partition among a plurality of first random access resource partitions.

[0078] Alternatively, the priority may be set for the terminal by a first network device via instruction information, where the first network device includes, but is not limited to, a base station, a core network device, etc.

[0079] Illustratively, the priority may be an NSAG priority in an existing mechanism, which may be set by a network device, e.g., a base station, a core network device, and may include an NSAG priority, etc.

[0080] Illustratively, the priority may be an additional priority set by the first network device for the NSAG, which differs from the NSAG priority in the above-mentioned existing mechanism, and the additional priority may or may not include the NSAG priority, and the present disclosure is not limited thereto.

[0081] Illustratively, the priority may be the priority of a random access resource partition.

[0082] This disclosure is not limited in terms of priority.

[0083] In some alternative embodiments, the first network device 102 may transmit first information to the terminal 101, where the first information is used by the terminal 101 to determine a first random access resource partition, where the number of first random access resource partitions is one, or the first information is used by the terminal 101 to determine one target random access resource partition for the current random access among multiple first random access resource partitions.

[0084] In one example, the first information may include random access resource partition configuration information, and the random access resource partition configuration information may satisfy at least one of the following: one random access resource partition is associated with a single NSAG; one random access resource partition is associated with multiple NSAGs, and the multiple NSAGs are determined by the RRC layer at the same time and are not provided to the MAC layer; and each NSAG is associated with one random access resource partition.

[0085] Correspondingly, the first information can be used by the terminal to determine one first random access resource partition.

[0086] In another example, the first information may include indication information, which is used by the terminal to determine one target random access resource partition for the current random access from the plurality of first random access resource partitions.

[0087] In some alternative embodiments, the second network device 103 can transmit network slice information to the first network device 102, which is used by the first network device 102 to determine multiple NSAGs associated with the one random access resource partition, and the multiple NSAGs are determined by the RRC layer of the terminal at the same time and are not provided to the MAC layer.

[0088] The network slice information includes at least one of a mapping relationship between a single network slice selection assistance information (S-NSSAI) and an NSAG, an NSAG priority, and region information corresponding to the mapping relationship, the region information including at least a tracking area identifier (TAI).

[0089] The network slice includes at least one of a network slice that allows a terminal to access the NSAG and a network slice that does not allow the terminal to register and use at the same time.

[0090] In the above embodiment, in the random access process triggered based on the network slice, the terminal can uniquely determine one target random access resource partition for the current random access, thereby improving the reliability of the random access process applied to the network slice trigger.

[0091] In an embodiment of the present disclosure, the target random access resource partition to be applied to the random access determined by the terminal is: Configuration needs to accommodate as many characteristics as possible, and providing as many dedicated settings for specific characteristics as possible.

[0092] For example, if the target random access resource partition satisfies the configuration needs corresponding to as many characteristics as possible, the target random access resource partition may be related to a network slice, and the characteristics may use a granularity of per NSAG. For example, the target random access resource partition may be the random access resource partition with the largest number of associated NSAGs.

[0093] For example, if the target random access resource partition satisfies the requirement of providing as many dedicated settings as possible for a specific characteristic, the target random access resource partition may be, for example, a random access resource partition associated with only a first NSAG, where the first NSAG includes one or more NSAGs determined by the RRC layer of the terminal and provided to the MAC layer.

[0094] Also, for example, a first network device may set a specific configuration for one or more characteristics, and the target random access resource partition may be associated with one or more characteristics having the specific configuration, and for a network slice, the characteristics may use a granularity of per NSAG, i.e., a first network device may set a specific configuration for one or more NSAGs, and the target random access resource partition may be associated with one or more NSAGs having the specific configuration.

[0095] Also for example, the target random access resource partition may be a random access resource partition whose associated NSAG priority satisfies a preset condition.

[0096] Alternatively, the priority may be determined by indication information sent by the first network device, and the indication information is used by the terminal to determine a target random access resource partition from the plurality of first random access resource partitions. The priority can be set for the terminal by a first network device via instruction information, where the first network device includes, but is not limited to, a base station, a core network device, etc.

[0097] Illustratively, the priority may be an NSAG priority in an existing mechanism, which may be set by a network device, e.g., a base station, a core network device, and may include an NSAG priority, etc.

[0098] Illustratively, the priority may be an additional priority set by the first network device for the NSAG, which differs from the NSAG priority in the above-mentioned existing mechanism, and the additional priority may or may not include the NSAG priority, and the present disclosure is not limited thereto.

[0099] Illustratively, the priority may be the priority of a random access resource partition.

[0100] Any manner in which a terminal determines a target random access resource partition that satisfies at least one of the above conditions or other conditions should fall within the scope of protection. The following first describes the method for determining a random access resource from the terminal side provided by the present disclosure.

[0101] An embodiment of the present disclosure provides a method for determining a random access resource. As shown in FIG. 2, FIG. 2 is a flowchart of a method for determining a random access resource according to an embodiment, which can be performed by a terminal. The method can include the following steps: In step 201, a first random access resource partition is determined.

[0102] In the embodiments of the present disclosure, the first random access resource partition may be a candidate random access resource for random access, and may specifically apply to a random access resource partition corresponding to the characteristics and / or combination of characteristics of the current random access process. The number of the first random access resource partitions may be one or more.

[0103] It is necessary to explain that for a terminal, visible characteristics and / or combinations of characteristics of the MAC layer refer to characteristics and / or combinations of characteristics that apply to random access, and visible characteristics and / or combinations of characteristics of the RRC layer refer to characteristics and / or combinations of characteristics that trigger random access.

[0104] Illustratively, the terminal determines the first random access resource partition based on the random access resource partition configuration sent by the first network device. The first network device includes, but is not limited to, a base station, an access network device, etc. The base station may be a 4G base station, a 5G base station, or a future 6G base station, and the access network device may be a 4G access network device, a 5G access network device, or a future 6G access network device, etc., but the present disclosure is not limited thereto. Optionally, the first network device 102 may also include a core network device such as an AMF.

[0105] In an embodiment of the present disclosure, the terminal may determine the first random access resource using any one of the following manners: Method 1: The terminal determines the random access resource partitions associated with all the first NSAGs as the first random access resource partitions.

[0106] In the embodiments of the present disclosure, the first NSAG refers to an NSAG determined by the RRC layer of the terminal and provided to the MAC layer for random access resource selection, and the number of first NSAGs may be one or more, and the present disclosure is not limited thereto.

[0107] In the first network device, in manner 1, the terminal can determine one first random access resource partition.

[0108] Illustratively, it is assumed that 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 the random access resource partition configuration via a system message, for example, SIB1, as follows: that random access resource partition #1 is associated with NSAG #1; The random access resource partition #2 is associated with NSAG #1 and NSAG #2.

[0109] In method 1 provided by the present application, the number of first NSAGs associated with random access resource partition #1 and random access resource partition #2 is 1 and 2, respectively, and the terminal determines random access resource partition #2, which has a larger number of associated first NSAGs, as the first random access resource partition.

[0110] It should be noted that, assuming that the number of first NSAGs is three and the random access resource partition configurations broadcast by the first network device via a system message, for example, SIB1, are associated with the most two first NSAGs, the terminal can abandon determining the first random access resource partition according to the random access resource partitions associated with all the first NSAGs. Alternatively, the terminal can determine the first random access resource partition according to the scheme of the prior art and further determine one target random access resource partition for the current random access in subsequent step 202.

[0111] Alternatively, step 201 may include the following steps: Step 201-1 involves making the random access resource partition associated with the first NSAG a second random access resource partition.

[0112] In this step, the terminal determines all of at least one random access resource partition in the associated first NSAG as the second random access resource partition.

[0113] In step 201-2, it is determined that the random access resource partition with the largest number of NSAGs in the associated first NSAGs from the second random access resource partition is the first random access resource partition. do .

[0114] Illustratively, it is assumed that 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 the random access resource partition configuration via a system message, for example, SIB1, as follows: that random access resource partition #1 is associated with NSAG #1; The random access resource partition #2 is associated with NSAG #1 and NSAG #2.

[0115] The terminal determines random access resource partition #1 and random access resource partition #2 as second random access resource partitions, and determines that the random access resource partition with the largest number of first NSAGs associated with the second random access resource partition is random access resource partition #2, and determines it as the first random access resource partition.

[0116] Scheme 2: The terminal determines a first random access resource partition based on the random access resource partition configuration information sent by the first network device.

[0117] In manner 2, the terminal may determine one first random access resource partition.

[0118] In one example, the random access resource partition configuration information is associated with a single NSAG, that is, each random access resource partition configured by the random access resource partition configuration information is associated with a single NSAG.

[0119] 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.

[0120] In another example, the random access resource partition configuration information is associated with multiple NSAGs.

[0121] Multiple NSAGs refer to multiple NSAGs that are determined by the RRC layer of the terminal at the same time and are not provided to the MAC layer.

[0122] In an embodiment of the present disclosure, the second network device can provide network slice information to the first network device, and the network slice information is used by the first network device to determine multiple NSAGs associated with the one random access resource partition. The second network device can include, but is not limited to, a base station, an access network device, etc. 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 the present disclosure is not limited thereto. Optionally, the second network device can further include a core network device.

[0123] In one example, the first network device and the second network device may be of the same or different types.

[0124] Illustratively, the first network device may be a base station and the second network device may also be a base station, and the two base stations may be the same or different, although the present disclosure is not limited in this respect.

[0125] Illustratively, the first network device may be a core network device, and the second network device may be a base station.

[0126] Illustratively, the first network device may be a base station, and the second network device may be a core network device.

[0127] Illustratively, the first network device may be a core network device, and the second network device may be a core network device, and the two core network devices may be the same type or different types of core network devices, for example, all may be AMFs, or one may be an AMF and the other may be a core network function device different from the AMF, and the present disclosure is not limited thereto.

[0128] The network slice information optionally includes, but is not limited to, at least one of a mapping relationship between an S-NSSAI and an NSAG, an NSAG priority, and area information corresponding to the mapping relationship, where the area information includes at least a TAI.

[0129] The NSAG priority here may be an NSAG priority in an existing mechanism, and may be set by a network device, for example, a base station, a core network device, and may include an NSAG priority, etc.

[0130] The network slice may include, but is not limited to, at least one of a network slice that allows a terminal to access an NSAG and a network slice that does not allow a terminal to simultaneously register and use the NSAG. The NSAG here may be any one NSAG, i.e., the network slice may include a network slice that allows a terminal to access any one NSAG.

[0131] A network slice that cannot be allowed to be registered and used simultaneously refers to a network slice that is determined by the first network device within the same period and does not allow a terminal to register and use simultaneously.

[0132] For example, random access resource partition #1 is associated with NSAG #1 and NSAG #3, and NSAG #1 and NSAG #3 are not allowed to be used for terminal registration at the same time.

[0133] In another example, in the random access resource partition configuration information, each NSAG is associated with one random access resource partition. It should be noted that each NSAG is associated with only one random access resource partition.

[0134] For example, if the random access resource partition configuration information includes random access resource partition #1 associated with NSAG #1, the random access resource partition configuration information does not include random access resource partitions associated with NSAG #1 and one or more other NSAGs, such as random access resource partition #2 associated with NSAG #1 and NSAG #2.

[0135] In step 202, determine one target random access resource partition from the first random access resource partition for the current random access.

[0136] In the embodiments of the present disclosure, if the number of first random access resource partitions determined by the terminal according to the above-mentioned Scheme 1 or Scheme 2 is 1, the terminal can directly determine the first random access resource partition as the target random access resource partition according to the related art.

[0137] In one example, when the number of first random access resource partitions determined by the terminal according to the above-mentioned Scheme 1 or Scheme 2 is plural, the terminal may further determine a target random access resource partition.

[0138] In an embodiment of the present 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; the first NSAG is associated with only the first NSAG, and the first NSAG includes an NSAG determined by the radio resource control (RRC) layer and provided to the media access control (MAC) layer; and the priority of the associated NSAG satisfies a predetermined condition.

[0139] In one example, the terminal determines, from a plurality of first random access resource partitions, a first random access resource partition having the largest number of associated NSAGs as a target random access resource partition.

[0140] In another example, the terminal may determine, from a plurality of first random access resource partitions, a first random access resource partition associated with only the first NSAG as a target random access resource partition.

[0141] The first NSAG includes one or more NSAGs determined by the RRC layer and provided to the MAC layer.

[0142] In another example, the terminal determines, from a plurality of first random access resource partitions, a first random access resource partition whose associated NSAG priority satisfies a preset condition as a target random access resource partition.

[0143] The preset condition here may be that a priority corresponding to a first random access resource partition is higher than a priority corresponding to another first random access resource partition.

[0144] The priority can be determined by indication information sent by the first network device, and the indication information is used to determine a target random access resource partition from a plurality of first random access resource partitions.

[0145] The priority can be set for the terminal by a first network device via instruction information, where the first network device includes, but is not limited to, a base station, a core network device, etc.

[0146] Illustratively, the priority may be an NSAG priority in an existing mechanism, which may be set by a network device, e.g., a base station, a core network device, and may include an NSAG priority, etc.

[0147] Illustratively, the priority may be an additional priority set by the first network device for the NSAG, which differs from the NSAG priority in the above-mentioned existing mechanism, and the additional priority may or may not include the NSAG priority, and the present disclosure is not limited thereto.

[0148] Illustratively, the priority may be the priority of a random access resource partition.

[0149] In another example, the terminal determines, among a plurality of first random access resource partitions, the first random access resource partition that has the largest number of associated NSAGs and is associated only with the first NSAGs, as the target random access resource partition.

[0150] In another example, a terminal determines, from a plurality of first random access resource partitions, a first random access resource partition that is associated with only a first NSAG and the priority of the associated NSAG satisfies a preset condition as a target random access resource partition.

[0151] In another example, a terminal determines, among a plurality of first random access resource partitions, a first random access resource partition that has the largest number of associated NSAGs, is associated only with first NSAGs, and the priority of the associated NSAGs satisfies a preset condition, as a target random access resource partition.

[0152] In one possible implementation manner, a target random access resource partition may be determined among a plurality of first random access resource partitions based on a terminal policy.

[0153] The terminal policy may be a policy established by the terminal based on its own traffic to determine one target random access resource partition among multiple first random access resource partitions, and the present disclosure does not limit the specific terminal policy.

[0154] Illustratively, the terminal policy may be to randomly select, or the terminal policy may be to select the one with the most random access resources, and the present disclosure is not limited thereto.

[0155] In another possible implementation manner, a target random access resource partition may be determined among a plurality of first random access resource partitions based on the indication information sent by the first network device.

[0156] In one example, the indication may be used to set priorities for multiple NSAGs.

[0157] Illustratively, the priority may be an NSAG priority in an existing mechanism, which may be set by a network device, e.g., a base station, a core network device, and may include an NSAG priority, etc.

[0158] Illustratively, the priority may be an additional priority set by the first network device for the NSAG, which differs from the NSAG priority in the above-mentioned existing mechanism, and the additional priority may or may not include the NSAG priority, and the present disclosure is not limited thereto.

[0159] Illustratively, the priority may be the priority of a random access resource partition.

[0160] The terminal can select, based on the indication information, a first random access resource partition whose priority satisfies a preset condition from among the plurality of first random access resource partitions as a target random access resource partition.

[0161] For example, the first NSAG is NSAG#1, NSAG#2, and the first network device broadcasts the random access resource partition configuration via a system message, for example, SIB1, as follows: that random access resource partition #1 is associated with NSAG #1; The random access resource partition #2 is associated with NSAG #2.

[0162] The terminal determines that the first random access resource partition includes random access resource partition #1 and random access resource partition #2.

[0163] The instruction information sent by the first network device sets priorities for NSAG#1 and NSAG#2, and the priority of NSAG#1 is higher than the priority of NSAG#2, so the terminal determines random access resource partition#1 as the target random access resource partition.

[0164] In another example, the indication information may 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.

[0165] The terminal may determine, as a target random access resource partition, a first random access resource partition corresponding to an NSAG with the largest number of associated NSAGs among the plurality of first random access resource partitions.

[0166] For example, the first NSAG is NSAG#1, NSAG#2, and the first network device broadcasts the random access resource partition configuration via a system message, for example, SIB1, as follows: that random access resource partition #1 is associated with NSAG #1; The random access resource partition #2 is associated with NSAG #1 and NSAG #2.

[0167] The terminal determines that the first random access resource partition includes random access resource partition #1 and random access resource partition #2.

[0168] The terminal receives instruction information sent by the first network device, and the instruction information can be used to instruct the terminal to determine a target random access resource partition based on the number of NSAGs associated with the random access resource partition, and the terminal determines random access resource partition #2 having the largest number of associated NSAGs as the target random access resource partition.

[0169] In another possible implementation manner, the target random access resource partition is determined among the plurality of first random access resource partitions based on a protocol contract.

[0170] Illustratively, the protocol may undertake to determine a target random access resource partition among a plurality of first random access resource partitions according to the number of NSAGs with which the terminal is associated.

[0171] Alternatively, the protocol may provide that the terminal determines the target random access resource partition based on the first random access resource partition associated with only the first NSAG.

[0172] Alternatively, the protocol may promise that the terminal determines a target random access resource partition among a plurality of first random access resource partitions according to a priority.

[0173] Or, the protocol may further promise that the terminal determines the target random access resource partition with the smallest or largest random access resource partition index value.

[0174] Alternatively, the protocol may ensure that the terminal randomly selects one of the multiple first random access resource partitions as the target random access resource partition.

[0175] The above is merely an exemplary description, and the protocol may also promise other contents. Any manner in which the terminal determines the target random access resource partition according to the protocol promise shall fall within the scope of protection of the present disclosure.

[0176] In another possible implementation manner, the terminal may determine a target random access resource partition among a plurality of first random access resource partitions based on the policy and the indication information sent by the first network device.

[0177] Illustratively, the terminal determines random access resource partitions that can be multiple 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 a terminal policy.

[0178] For example, random access resource partition #1 is associated with NSAG #1, and random access resource partition #2 is associated with NSAG #1 and NSAG #2.

[0179] The first random access resource partition includes random access resource partition #1 and random access resource partition #2, and the indication information indicates the priority of the random access resource partition. The terminal determines that both the random access resource partition #1 and the random access resource partition #2 can be the target random access resource partition according to the indication information.

[0180] The terminal may randomly select random access resource partition #2 as the target random access resource partition according to the terminal policy.

[0181] In another possible implementation manner, the target random access resource partition may be determined among the plurality of first random access resource partitions based on protocol agreements and terminal policies.

[0182] The implementation is similar to the embodiment described above and will not be further described here.

[0183] In another possible implementation manner, a target random access resource partition can be determined among a plurality of first random access resource partitions based on a protocol promise and indication information sent by the first network device.

[0184] Illustratively, the protocol promises that the terminal determines a target random access resource partition among a plurality of first random access resource partitions based on the indication information sent by the first network device.

[0185] In another possible implementation manner, a target random access resource partition can be determined among a plurality of first random access resource partitions based on terminal policies, protocol agreements, and instruction information sent by the first network device.

[0186] The above is merely an exemplary description. In actual applications, any manner in which a terminal uniquely determines a target random access resource partition from a plurality of first random access resource partitions should fall within the protection scope.

[0187] In the above embodiment, in the random access process triggered based on the network slice, the terminal can determine one first random access resource partition, thereby improving the reliability of the random access process applied to the network slice trigger.

[0188] In some alternative embodiments, refer to FIG. 3 , which is a flowchart of a method for determining a random access resource according to an embodiment, which can be performed by a terminal, and the method can include the following steps: In step 301, determine one target random access resource partition for the current random access from a plurality of first random access resource partitions.

[0189] In the embodiment of the present disclosure, the terminal may determine the first random access resource partition using a related technique.

[0190] As an example, assume that the first NSAG that the RRC layer provides to the MAC layer is NSAG1, and the characteristics that trigger the random access process include NSAG#1 and CE.

[0191] The network device broadcasts the random access resource partition configuration via a system message, for example, System Information Block 1 (SIB1). that random access resource partition #1 is associated with NSAG #1; The random access resource partition #2 is associated with NSAG #1 and NSAG #2.

[0192] The terminal determines that the first random access resource partition includes random access resource partition #1 and random access resource partition #2.

[0193] For example, the first NSAGs determined and provided by the assumed RRC layer to the MAC layer are NSAG#1 and NSAG#2, and the characteristics triggering random access include NSAG#1 and NSAG#2, and have the same NSAG priority. The network device may inform the random access resource partition configuration broadcasted by the SIB1 through a system message, for example, that random access resource partition #1 is associated with NSAG #1; The random access resource partition #2 is associated with NSAG #2.

[0194] The terminal determines that the first random access resource partition includes random access resource partition #1 and random access resource partition #2.

[0195] If the terminal determines multiple first random access resource partitions, it may determine a target random access resource partition using the following scheme: In an embodiment of the present disclosure, the target random access resource partition finally determined by the terminal may satisfy at least one of the following: the first random access resource partition has the largest number of associated NSAGs; the first NSAG is associated only with a first NSAG, and the first NSAG includes one or more NSAGs determined by a radio resource control (RRC) layer and provided to a media access control (MAC) layer; and the priority of the associated NSAGs satisfies a preset condition. In one example, the terminal determines, from the multiple first random access resource partitions, the first random access resource partition with the largest number of associated NSAGs as the target random access resource partition.

[0196] In another example, the terminal determines, from a plurality of first random access resource partitions, a first random access resource partition associated with only the first NSAG as a target random access resource partition.

[0197] The number of the first NSAGs may be one or more, and the first NSAGs include one or more NSAGs determined by the RRC layer and provided to the MAC layer.

[0198] In another example, the terminal determines, from a plurality of first random access resource partitions, a first random access resource partition whose associated NSAG priority satisfies a preset condition as a target random access resource partition.

[0199] The preset condition here may be that a priority corresponding to a first random access resource partition is higher than a priority corresponding to another first random access resource partition.

[0200] The priority can be determined by indication information sent by the first network device, and the indication information is used to determine a target random access resource partition among a plurality of first random access resource partitions.

[0201] The priority can be set for the terminal by a first network device via instruction information, where the first network device includes, but is not limited to, a base station, a core network device, etc.

[0202] Illustratively, the priority may be an NSAG priority in an existing mechanism, which may be set by a network device, e.g., a base station, a core network device, and may include an NSAG priority, etc.

[0203] Illustratively, the priority may be an additional priority set by the first network device for the NSAG, which differs from the NSAG priority in the above-mentioned existing mechanism, and the additional priority may or may not include the NSAG priority, and the present disclosure is not limited thereto.

[0204] Illustratively, the priority may be the priority of a random access resource partition.

[0205] In another example, the terminal determines, among a plurality of first random access resource partitions, the first random access resource partition that has the largest number of associated NSAGs and is associated only with the first NSAGs, as the target random access resource partition.

[0206] In another example, a terminal determines, from a plurality of first random access resource partitions, a first random access resource partition that is associated with only a first NSAG and the priority of the associated NSAG satisfies a preset condition as a target random access resource partition.

[0207] In another example, a terminal determines, among a plurality of first random access resource partitions, a first random access resource partition that has the largest number of associated NSAGs, is associated only with first NSAGs, and the priority of the associated NSAGs satisfies a preset condition, as a target random access resource partition.

[0208] In one possible implementation manner, a target random access resource partition may be determined among a plurality of first random access resource partitions based on a terminal policy.

[0209] The terminal policy may be a policy established by the terminal based on its own traffic to determine one target random access resource partition among multiple first random access resource partitions, and the present disclosure does not limit the specific terminal policy.

[0210] Illustratively, the terminal policy may be to randomly select, or the terminal policy may be to select the one with the most random access resources, and the present disclosure is not limited thereto.

[0211] In another possible implementation manner, a target random access resource partition may be determined among a plurality of first random access resource partitions based on the indication information sent by the first network device.

[0212] In one example, the indication may be used to set priorities for multiple NSAGs.

[0213] Illustratively, the priority may be an NSAG priority in an existing mechanism, which may be set by a network device, e.g., a base station, a core network device, and may include an NSAG priority, etc.

[0214] Illustratively, the priority may be an additional priority set by the first network device for the NSAG, which differs from the NSAG priority in the above-mentioned existing mechanism, and the additional priority may or may not include the NSAG priority, and the present disclosure is not limited thereto.

[0215] Illustratively, the priority may be the priority of a random access resource partition.

[0216] The terminal can select, based on the indication information, a first random access resource partition whose priority satisfies a preset condition from among the plurality of first random access resource partitions as a target random access resource partition.

[0217] For example, the first NSAG is NSAG#1, NSAG#2, and the first network device broadcasts the random access resource partition configuration via a system message, for example, SIB1, as follows: that random access resource partition #1 is associated with NSAG #1; The random access resource partition #2 is associated with NSAG #2.

[0218] The terminal determines that the first random access resource partition includes random access resource partition #1 and random access resource partition #2.

[0219] The instruction information sent by the first network device sets priorities for NSAG#1 and NSAG#2, and the priority of NSAG#1 is higher than the priority of NSAG#2, so the terminal determines random access resource partition#1 as the target random access resource partition.

[0220] In another example, the indication information may 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.

[0221] The terminal may determine, as a target random access resource partition, a first random access resource partition corresponding to an NSAG with the largest number of associated NSAGs among the plurality of first random access resource partitions.

[0222] For example, the first NSAG is NSAG#1, NSAG#2, and the first network device broadcasts the random access resource partition configuration via a system message, for example, SIB1, as follows: that random access resource partition #1 is associated with NSAG #1; The random access resource partition #2 is associated with NSAG #1 and NSAG #2.

[0223] The terminal determines that the first random access resource partition includes random access resource partition #1 and random access resource partition #2.

[0224] The terminal receives instruction information sent by the first network device, and the instruction information can be used to instruct the terminal to determine a target random access resource partition based on the number of NSAGs associated with the random access resource partition, and the terminal determines random access resource partition #2 having the largest number of associated NSAGs as the target random access resource partition.

[0225] Another possible implementation method includes determining a target random access resource partition among a plurality of first random access resource partitions based on a protocol agreement.

[0226] Illustratively, the protocol may undertake to determine a target random access resource partition among a plurality of first random access resource partitions according to the number of NSAGs with which the terminal is associated.

[0227] Alternatively, the protocol may provide that the terminal determines the target random access resource partition based on the first random access resource partition associated with only the first NSAG.

[0228] Alternatively, the protocol may promise that the terminal determines a target random access resource partition among a plurality of first random access resource partitions according to a priority.

[0229] Or, the protocol may further promise that the terminal determines the target random access resource partition with the smallest or largest random access resource partition index value.

[0230] Alternatively, the protocol may ensure that the terminal randomly selects one of the multiple first random access resource partitions as the target random access resource partition.

[0231] The above is merely an exemplary description, and the protocol may also promise other contents. Any manner in which the terminal determines the target random access resource partition according to the protocol promise shall fall within the scope of protection of the present disclosure.

[0232] In another possible implementation manner, the terminal may determine a target random access resource partition among a plurality of first random access resource partitions based on the policy and the indication information sent by the first network device.

[0233] Illustratively, the terminal determines random access resource partitions that can be multiple 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 a terminal policy.

[0234] For example, random access resource partition #1 is associated with NSAG #1, and random access resource partition #2 is associated with NSAG #1 and NSAG #2.

[0235] The first random access resource partition includes random access resource partition #1 and random access resource partition #2, and the indication information indicates the priority of the random access resource partition. The terminal determines that both the random access resource partition #1 and the random access resource partition #2 can be the target random access resource partition according to the indication information.

[0236] The terminal may randomly select random access resource partition #2 as the target random access resource partition according to the terminal policy.

[0237] In another possible implementation manner, the target random access resource partition may be determined among the plurality of first random access resource partitions based on protocol agreements and terminal policies.

[0238] The implementation is similar to the embodiment described above and will not be further described here.

[0239] In another possible implementation manner, a target random access resource partition can be determined among a plurality of first random access resource partitions based on a protocol promise and indication information sent by the first network device.

[0240] Illustratively, the protocol promises that the terminal determines a target random access resource partition among a plurality of first random access resource partitions based on the indication information sent by the first network device. In another possible implementation manner, a target random access resource partition can be determined among a plurality of first random access resource partitions based on terminal policies, protocol agreements, and instruction information sent by the first network device.

[0241] The above is merely an exemplary description. In actual applications, any manner in which a terminal uniquely determines a target random access resource partition from a plurality of first random access resource partitions should fall within the protection scope.

[0242] In the above embodiment, the terminal can determine one target random access resource partition to apply to random access among multiple first random access resource partitions, thereby improving the reliability of the random access process applied to the network slice trigger.

[0243] Next, a method for determining the random access resource provided by the present disclosure from the first network device side will be described.

[0244] An embodiment of the present disclosure provides a method for determining a random access resource. Refer to FIG. 4A, which is a flowchart of a method for determining a random access resource according to an embodiment, which can be performed by a first network device, including but not limited to a base station, an access network device, etc. The base station is a 4G base station, a 5G base station, or a future 6G base station, and the access network device is a 4G access network device, a 5G access network device, or a future 6G access network device, etc., and the present disclosure is not limited thereto. Optionally, the first network device may further include a core network device. The method may include the following steps: In step 401, first information is transmitted to the terminal.

[0245] In one possible implementation manner, the first information may be used by the terminal to determine one first random access resource partition.

[0246] The first information may include random access resource partition configuration information, where the random access resource partition configuration information is used by the terminal to determine the first random access resource partition.

[0247] In one example, the random access resource partition configuration information is associated with a single NSAG, that is, each random access resource partition configured by the random access resource partition configuration information is associated with a single NSAG.

[0248] In another example, the random access resource partition configuration information is associated with multiple NSAGs.

[0249] Multiple NSAGs are determined by the RRC layer of the terminal at the same time and are not provided to the MAC layer.

[0250] In an embodiment of the present disclosure, a first network device can receive network slice information sent by a second network device, and further determine, according to the network slice information, multiple NSAGs that are not simultaneously included in the first NSAG.

[0251] The network slice information is used to determine multiple NSAGs in which the first network device is not simultaneously included in the first NSAG.

[0252] The second network device includes, but is not limited to, a base station, an access network device, etc. The base station is a 4G base station, a 5G base station, or a future 6G base station, and the access network device is a 4G access network device, a 5G access network device, or a future 6G access network device, etc., and the present disclosure is not limited thereto. Optionally, the second network device may further include a core network device.

[0253] In one example, the first network device and the second network device may be of the same or different types.

[0254] Illustratively, the first network device may be a base station and the second network device may also be a base station, and the two base stations may be the same or different, although the present disclosure is not limited in this respect.

[0255] Illustratively, the first network device may be a core network device, and the second network device may be a base station.

[0256] Illustratively, the first network device may be a base station, and the second network device may be a core network device.

[0257] Illustratively, the first network device may be a core network device, and the second network device may be a core network device, and the two core network devices may be the same type or different types of core network devices, and the present disclosure is not limited thereto.

[0258] Furthermore, if the first network device and the second network device are the same type of network device, they may be the same device or different devices, and if they are the same device, illustratively, the network slice information can be sent to the MAC layer by the RRC layer of the network device.

[0259] Optionally, the network slice information includes at least one of, but is not limited to, a mapping relationship between the S-NSSAI and the NSAG, an NSAG priority, and area information corresponding to the mapping relationship, where the area information includes at least the TAI.

[0260] The network slice may include, but is not limited to, at least one of a network slice that allows a terminal to access an NSAG and a network slice that does not allow a terminal to simultaneously register and use the NSAG. The NSAG here may be any one NSAG, i.e., the network slice may include a network slice that allows a terminal to access any one NSAG.

[0261] A network slice that cannot be allowed to be registered and used simultaneously refers to a network slice that is determined by the first network device within the same period and does not allow a terminal to register and use simultaneously.

[0262] In another example, in the random access resource partition configuration information, each NSAG is associated with only one random access resource partition.

[0263] The manner in which the terminal side determines the first random access resource partition based on the random access partition configuration information has been described on the terminal side, specifically, refer to the manner 2 in which the terminal side determines the first random access resource partition, and will not be further described here.

[0264] If the number of the first random access resource partitions determined by the terminal is 1, the terminal may directly determine the first random access resource partition as the target random access resource partition according to the related art.

[0265] If the number of first random access resource partitions determined by the terminal is plural, the terminal may also determine a target random access resource partition among the plural first random access resource partitions. The determination manner is similar to that in step 202, and will not be further described here.

[0266] In another possible implementation manner, the first information may include indication information, which is used by the terminal to determine a target random access resource partition from the plurality of first random access resource partitions.

[0267] In one example, the indication information can be used to indicate priority for multiple NSAGs.

[0268] Illustratively, the priority may be an NSAG priority in an existing mechanism, which may be set by a network device, e.g., a base station, a core network device, and may include an NSAG priority, etc.

[0269] Illustratively, the priority may be an additional priority set by the first network device for the NSAG, which differs from the NSAG priority in the above-mentioned existing mechanism, and the additional priority may or may not include the NSAG priority, and the present disclosure is not limited thereto.

[0270] Illustratively, the priority may be the priority of a random access resource partition.

[0271] The terminal can select, based on the indication information sent by the first network device, a first random access resource partition whose priority satisfies a preset condition among a plurality of first random access resource partitions as a target random access resource partition.

[0272] The preset condition here may be that a priority corresponding to a first random access resource partition is higher than a priority corresponding to another first random access resource partition.

[0273] In another example, the indication information may 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.

[0274] The terminal may determine a target random access resource partition from the plurality of first random access resource partitions according to the indication information.

[0275] Alternatively, the terminals can jointly determine the target random access resource partition by combining protocol agreements and terminal policies. The specific manner is similar to the manner in which the terminals determine the target random access resource partition from multiple first random access resource partitions in step 301 above, and will not be further described here.

[0276] In the above embodiment, the first network device may send first information to the terminal, and the first information is used by the terminal to determine one first random access resource partition or to determine one target random access resource partition to apply to random access among the multiple first random access resource partitions. In the random access process triggered based on network slicing, the terminal can uniquely determine one target random access resource partition to apply to random access, thereby improving the reliability of the random access process applied to network slicing trigger.

[0277] An embodiment of the present disclosure provides a method for determining a random access resource. Refer to FIG. 4B, which is a flowchart of a method for determining a random access resource according to an embodiment, which can be performed by a second network device, including but not limited to a base station, an access network device, etc. The base station is a 4G base station, a 5G base station, or a future 6G base station, and the access network device is a 4G access network device, a 5G access network device, or a future 6G access network device, etc., and the present disclosure is not limited thereto. Optionally, the second network device may further include a core network device. The method may include the following steps: In step 401', network slice information is sent to a first network device.

[0278] Optionally, the network slice information includes at least one of, but is not limited to, a mapping relationship between the S-NSSAI and the NSAG, an NSAG priority, and area information corresponding to the mapping relationship, where the area information includes at least the TAI.

[0279] The network slice may include, but is not limited to, at least one of a network slice that allows a terminal to access an NSAG and a network slice that does not allow a terminal to simultaneously register and use the NSAG. The NSAG here may be any one NSAG, i.e., the network slice may include a network slice that allows a terminal to access any one NSAG.

[0280] A network slice that cannot be allowed to be registered and used simultaneously refers to a network slice that is determined by the first network device within the same period and does not allow a terminal to register and use simultaneously.

[0281] The first network device may determine, based on the network slice information, multiple NSAGs associated with one random access resource partition.

[0282] Multiple NSAGs refer to multiple NSAGs that are determined by the RRC layer of the terminal at the same time and are not provided to the MAC layer.

[0283] In the above embodiment, the second network device provides network slice information for the first network device, allowing the first network device to determine multiple NSAGs associated with one random access resource partition, and further configures random access resource partition configuration information for the terminal, which is simple to implement and has high availability.

[0284] In some alternative embodiments, refer to FIG. 5, which is a flowchart of a method for determining a random access resource according to an embodiment, which is applied to the system shown in FIG. 1, and which can be performed by the terminal 101, and includes the following steps: In step 501, the terminal 101 determines the random access resource partitions associated with all the first NSAGs as the first random access resource partitions.

[0285] In an embodiment of the present disclosure, the terminal may determine, based on the random access resource configuration information sent by the first network device, all the random access resource partitions associated with the first NSAGs as the first random access resource partitions. This embodiment is not limited to the specific configuration content of the random access resource partition configuration information sent by the first network device.

[0286] The first NSAG is determined by the radio resource control (RRC) layer and includes one or more NSAGs to provide to the media access control (MAC) layer.

[0287] If the number of the first random access resource partitions is 1, the terminal may directly determine the first random access resource partition as the target random access resource partition according to the related art.

[0288] If the number of the first random access resource partitions is plural, the terminal may continue to determine one target random access resource partition according to step 202.

[0289] It should be noted that the terminal may further, according to the above-mentioned scheme of steps 201-1 to 201-2 (not shown in FIG. 5), first determine the random access resource partition associated with the first NSAG as the second random access resource partition, and then determine from the second random access resource partition that the random access resource partition with the largest number of NSAGs in the associated first NSAG is the first random access resource partition. The present disclosure is not limited thereto.

[0290] In the above embodiment, in the random access process triggered based on the network slice, the terminal can determine one first random access resource partition, thereby improving the reliability of the random access process applied to the network slice trigger.

[0291] In some alternative embodiments, refer to FIG. 6, which is a flowchart of a method for determining a random access resource according to an embodiment, which can be applied to the system shown in FIG. 1, and includes the following steps: In step 600, the second network device 103 sends network slice information to the first network device 102.

[0292] Optionally, the network slice information includes at least one of, but is not limited to, a mapping relationship between the S-NSSAI and the NSAG, an NSAG priority, and area information corresponding to the mapping relationship, where the area information includes at least the TAI.

[0293] The network slice may include, but is not limited to, at least one of a network slice that allows a terminal to access an NSAG and a network slice that does not allow a terminal to simultaneously register and use the NSAG. The NSAG here may be any one NSAG, i.e., the network slice may include a network slice that allows a terminal to access any one NSAG.

[0294] A network slice that cannot be allowed to be registered and used simultaneously refers to a network slice that is determined by the first network device within the same period and does not allow a terminal to register and use simultaneously.

[0295] The first network device can determine, based on the network slice information, multiple NSAGs that are not simultaneously included in the first NSAG.

[0296] The first NSAG includes one or more NSAGs determined by the RRC layer of the terminal and provided to the MAC layer.

[0297] It should be noted that step 600 can be selectively performed, i.e., if the random access resource partition configuration information configured by the subsequent first network device 102 for the terminal 101 is unrelated to the above-mentioned multiple NSAGs, step 600 may not be performed.

[0298] In step 601, the first network device 102 sends random access resource partition configuration information to the terminal 101.

[0299] In an embodiment of the present disclosure, the random access resource partition configuration information can satisfy at least one of the following: one random access resource partition is associated with a single NSAG; one random access resource partition is associated with multiple NSAGs, and the multiple NSAGs are determined by the RRC layer of the terminal at the same time and are not provided to the MAC layer; and each NSAG is associated with only one random access resource partition.

[0300] The specific content of the random access resource partition configuration information has already been described in step 401 and will not be described here.

[0301] In step 602, the terminal 101 determines a first random access resource partition based on the random access resource partition configuration information.

[0302] To ensure that the random access resource partition configuration information satisfies at least one of the above conditions, the terminal determines the first random access resource partition based on the random access resource partition configuration information, and the determination manner is similar to the manner 2 in step 201 above, and will not be further described here.

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

[0304] If the number of the first random access resource partitions is plural, the terminal may continue to determine one target random access resource partition according to step 202.

[0305] In the above embodiment, the first network device is limited to ensure that the random access resource partitions configured by the first network device meet the specified conditions, and the terminal determines one first random access resource partition, thereby improving the reliability of the random access process applied to the network slice trigger.

[0306] In some alternative embodiments, refer to FIG. 7, which is a flowchart of a method for determining a random access resource according to an embodiment, which can be applied to the system shown in FIG. 1, which can be executed by the terminal 101, and which includes the following steps: In step 701, the terminal 101 determines one target random access resource partition for the current random access from a plurality of first random access resource partitions.

[0307] In an embodiment of the present disclosure, the terminal 101 can determine the first random access resource partition using the above-mentioned Scheme 1, Scheme 2, or Scheme 3. If the number of first random access resource partitions is multiple, in one possible implementation manner, the terminal can determine a target random access resource partition from the multiple first random access resource partitions based on at least one of a terminal policy, a protocol agreement, and indication information sent by the network.

[0308] The specific determination method is similar to step 202 or 301 above, and will not be further described here.

[0309] In one example, the terminal may select one of the first random access resource partitions as a target random access resource partition to apply to the random access according to a terminal policy.

[0310] The terminal policy may be randomly selected.

[0311] In one example, the terminal may determine a target random access resource partition in a plurality of first random access resource partitions based on the indication information sent by the first network device.

[0312] 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.

[0313] In this case, if the number of NSAGs associated with the plurality of first random access resource partitions is the largest, the terminal may determine one of them as the target random access resource partition based on protocol agreement and / or terminal policy.

[0314] For example, one can be randomly selected as the target random access resource partition according to a terminal policy.

[0315] For example, the target random access resource partition may further be determined to be the one with the smallest random access resource partition index value according to protocol conventions.

[0316] For example, it may further determine, according to protocol agreement and terminal policy, the one with the most random access resources included in the plurality of first random access resource partitions as the target random access resource partition.

[0317] In the above embodiment, in the random access process triggered based on the network slice, the terminal can determine one target random access resource partition to apply to the random access, thereby improving the reliability of the random access process applied to the network slice trigger.
