As shown in FIG1 , the method provided in the embodiment of the present disclosure can be applied to a communication system 100, which may include a terminal 101 and a network device 102. It should be noted that the communication system 100 may also include other devices, and the present disclosure does not limit the devices included in the communication system 100.

[0146] In some embodiments, the terminal 101 includes, for example, a mobile phone, a wearable device, an Internet of Things device, a car with communication function, a smart car, a tablet computer, a computer with wireless transceiver function, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal device in industrial control, a wireless terminal device in self-driving, a wireless terminal device in remote medical surgery, a wireless terminal device in a smart grid, a wireless terminal device in transportation safety, a wireless terminal device in a smart city, and at least one of a wireless terminal device in a smart home, but is not limited thereto.

In this case, the interfaces between or within the access network devices involved in the embodiments of the present disclosure can be transformed into internal interfaces of the Open RAN, and the processes and information interactions between these internal interfaces can be implemented through software or programs.

[0150] In some embodiments, the access network device can be composed of a centralized unit (CU) and a distributed unit (DU), where the CU can also be called a control unit. The CU-DU structure can be used to split the protocol layer of the access network device, with the functions of some protocol layers centrally controlled by the CU, and the functions of the remaining part or all of the protocol layers distributed in the DU, which is centrally controlled by the CU, but is not limited to this.

[0151] In some embodiments, a core network device may be a device including one or more network elements, or may be multiple devices or device groups, each including all or part of the one or more network elements. The network element may be virtual or physical. The core network may include, for example, at least one of an Evolved Packet Core (EPC), a 5G Core Network (5GCN), and a Next Generation Core (NGC).

[0152] It can be understood that the communication system described in the embodiment of the present disclosure is for the purpose of more clearly illustrating the technical solution of the embodiment of the present disclosure, and does not constitute a limitation on the technical solution proposed in the embodiment of the present disclosure. Ordinary technicians in this field can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution proposed in the embodiment of the present disclosure is also applicable to similar technical problems.

[0153] The following embodiments of the present disclosure may be applied to the communication system 100 shown in FIG1 , or a portion thereof, but are not limited thereto. The entities shown in FIG1 are illustrative only. The communication system may include all or part of the entities shown in FIG1 , or may include other entities outside of FIG1 . The number and form of the entities are arbitrary, and the entities may be physical or virtual. The connection relationships between the entities are illustrative only. The entities may be connected or disconnected, and the connection may be in any manner, including direct or indirect, wired or wireless.

[0154] The embodiments of the present disclosure can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), future radio access (FRA), new radio access technology (RAT), new radio (NR), new radio access (NX), future generation radio access (FX), Global System for Mobile communications (GSM (registered trademark)), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.20, Ultra-WideBand (UWB), Bluetooth (registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X), systems utilizing other communication methods, and next-generation systems based on and extending these methods. Furthermore, a combination of multiple systems (e.g., a combination of LTE or LTE-A with 5G) may also be employed.

[0155] In some embodiments, the network device may configure corresponding RACH partitions for different characteristics / characteristic combinations. Subsequently, the terminal may initiate random access based on the RACH partition resources, and the network device may determine the corresponding characteristics / characteristic combinations based on the RACH partitions fed back by the terminal.

[0156] Optionally, the terminal first determines the characteristic or characteristic combination that triggers the RACH, and determines whether there is an available RACH resource corresponding to the characteristic / characteristic combination that triggers RA based on the RACH partition configuration provided by the base station. If not, the legacy RACH resource (i.e., a RACH resource that is not associated with any characteristic indication) is selected. If there is one, the RACH resource is selected. If there are multiple RACH resources, resource selection is performed based on the characteristic priority configured by the network.

[0157] Optionally, due to limitations in random access resources and actual network deployment, the network may not provide specific RACH partitions for all feature combinations. This means that some feature combinations may not have corresponding RACH partitions. In this case, the terminal's MAC layer performs RACH partition selection based on the feature priority configured by the network, prioritizing high-priority features to find corresponding RACH partitions. This means that the RACH partition ultimately selected by the terminal may not support all features / feature combinations applicable to this RACH request.

[0158] In some embodiments, from the perspective of the network device, the base station provides the supported NSAG and the corresponding configuration of the NSAG to the terminal for slice-based cell reselection and RACH configuration enhancement. At the same time, the core network sends the NSAG information (including the correspondence between S-NSSAI and NSAG, NSAG priority and corresponding TAI) and S-NSSAI to the terminal through NAS signaling, so that the terminal can map the required S-NSSAI to the NSAG and perform cell reselection and RA based on the NSAG configuration.

[0159] From the terminal's perspective, the terminal receives the S-NSSAI (S) and NSAG information (including the correspondence between S-NSSAI and NSAG, as well as NSAG priority and TAI information) issued by the core network through NAS signaling. The terminal NAS layer passes one or more slices and slice grouping information to the AS layer for the AS layer to determine the NSAG ID for cell selection and reselection.

[0160] FIG2 is an interactive diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG2 , the embodiment of the present disclosure relates to a communication method, and the method includes:

[0161] Step S2101: The terminal sends third information.

[0162] In some embodiments, the network device receives third information.

[0163] In some embodiments, the third information is used to indicate that the terminal supports sending the first information. In some embodiments, the third information is used to indicate that the terminal supports sending network slice information that triggers RA. In some embodiments, the third information is used to indicate that the terminal has the capability to support sending the first information. In some embodiments, the third information is used to indicate that the terminal has a first capability, and the first capability is used to indicate that the terminal supports sending the first information. Alternatively, the first capability is used to indicate that the terminal supports sending network slice information that triggers RA.

[0164] In some embodiments, the name of the third information is not limited, and may be, for example, indication information, capability information, capability indication information, etc.

[0165] For example, the terminal sends capability indication information, which is used to indicate that the terminal supports sending network slice information for the network device to determine to trigger RA. Alternatively, the capability indication information is used to indicate that the terminal has a first capability, which means that the terminal supports sending network slice information for the network device to determine to trigger RA.

[0166] In some embodiments, the first information is used by the network device to determine the network slice information of the terminal triggering RA. In some embodiments, the first information is used to indicate the network slice information of the terminal triggering RA.

[0167] In some embodiments, the name of the first information is not limited, and may be, for example, indication information, reporting information, or other information.

[0168] It should be noted that step S2101 is an optional step. In another embodiment, step S2101 may not be performed.

[0169] Step S2102: The terminal records the first information.

[0170] In some embodiments, after triggering RA, the terminal can record the network slice information that triggered RA and then send the first information later.

[0171] In some embodiments, recording the first information by the terminal may also be referred to as storing the first information, or caching the first information, or saving the first information, which is not limited in the embodiments of the present disclosure.

[0172] In some embodiments, the first information is recorded in a report variable. In some embodiments, the report variable includes random access information. Alternatively, it can be understood that the report variable refers to a report variable including any random access information.

[0173] Optionally, the report variable includes at least one of the following:

[0174] RA reported variables;

[0175] RLF report variables;

[0176] CEF reports variables;

[0177] SHR reporting variables.

[0178] That is, in the embodiment of the present disclosure, the terminal may record the first information in an RA report variable, or in an RLF report variable, or in a CEF report variable, or in an SHR report variable.

[0179] In some embodiments, the first information includes at least one of the following:

[0180] (1) Time point information: The time point is used to indicate the time point when the terminal triggers RA or the time point when the first information is recorded.

[0181] It should be noted that, when the terminal records the first information, the first information includes time point information.

[0182] In some embodiments, the time point information refers to the time when the terminal triggers the RA or the time when the first information is recorded.

[0183] In some embodiments, the time point information is an absolute time point, or the time point information can also be represented by an offset value, that is, taking a certain time point as the starting point, the time point after the offset value is the time point information.

[0184] It should be noted that the embodiments of the present disclosure are all examples, and the time point information may also be a time point in other ways.

[0185] In some embodiments, after receiving the time point information included in the first information, the network device can determine the corresponding network configuration based on the time point information, and then determine the network slice information for the terminal to trigger RA based on the network configuration.

[0186] (2) Duration information: The duration information is used to indicate the duration between the time point when the terminal triggers the RA or the time point when the first information is recorded and the time point when the first information is sent.

[0187] In some embodiments, the network device can determine the network configuration corresponding to the time point of triggering RA or recording the first information based on the duration information, and then determine the network slice information that triggers RA based on the network configuration.

[0188] (3) Configuration information, which includes the mapping relationship of network slice information.

[0189] In some embodiments, after the network device receives the configuration information, it can determine the network slice information that triggers RA based on the mapping relationship included in the configuration information.

[0190] In some embodiments, the mapping relationship includes the correspondence between network slice information and RA resources.

[0191] In some embodiments, the mapping relationship includes relevant mapping information of the network slice group, including the mapping relationship between the network slice group identifier and the S-NSSAI identifier, the valid area information of the mapping relationship, and at least one item of the usage information of the mapping relationship.

[0192] (4) Network slice information that triggers RA.

[0193] In some embodiments, the terminal directly reports the network slice information that triggers RA.

[0194] In some embodiments, the network device can determine the network slice information that triggers RA based on the network slice information of the RA.

[0195] In some embodiments, the terminal not only sends the network slice information that triggers RA, but also sends the mapping relationship of the network slice information included in the configuration information to the network device. The network device reversely determines the corresponding mapping relationship based on the mapping relationship, and then determines or optimizes the RA configuration corresponding to S-NSSSAI based on the determined mapping relationship and network slice information.

[0196] In some embodiments, the terminal not only sends the network slice information that triggers RA, but also sends the time point information and / or duration information to the network device. The network device reversely determines the corresponding mapping relationship based on the time point information and / or duration information, and then determines or optimizes the RA configuration corresponding to the S-NSSSAI based on the determined mapping relationship and network slice information.

[0197] It should be noted that the network slice information in the embodiment of the present disclosure includes at least network slice group identification information NSAG ID, and NSAG ID is used to indicate NSAG.

[0201] In some embodiments, the network slice information is not included in SIB16 and / or proprietary signaling.

[0202] (2) Network slice information is the network slice information used for RA.

[0203] It should be noted that the embodiments of the present disclosure involve RA, which includes various situations. In some embodiments, the RA includes a two-step RA, or a four-step RA; the RA is a contention-based RA, or the RA is a non-contention-based RA.

[0204] In some embodiments, the NSAG is associated with the S-NSSAI that triggers RA, and the NSAG is not included in SIB16 and / or proprietary signaling.

[0205] In some embodiments, the NSAG is associated with the S-NSSAI that triggers RA, and the NSAG is included in SIB1.

[0206] In some embodiments, the NSAG is associated with the S-NSSAI that triggers RA, and the NSAG is included in SIB1 but not in SIB16 and / or proprietary signaling.

[0207] Step S2103: The network device sends the second information.

[0208] In some embodiments, the second information is used to indicate a request for network slicing information. In some embodiments, the name of the second information is not limited, and it can be, for example, request information, indication information, etc.

[0209] In an embodiment of the present disclosure, the network device can actively request the terminal to send network slice information that triggers RA, so the network device can send second information and request network slice information through the second information.

[0210] In some embodiments, the network device receives the third information and determines that the terminal supports sending network slice information that triggers RA, so the network device sends the second information to request the first information when the first information is needed.

[0211] Step S2104: The terminal sends the first information.

[0212] In some embodiments, a network device receives first information.

[0213] In some embodiments, the terminal receives the second information and determines based on the second information that the network device requests network slicing information, so the terminal receives the second information and sends the first information.

[0214] It should be noted that the disclosed embodiment uses steps S2103-S2104 as an example in which the network device requests the terminal to send the first information used by the network device to determine network slice information. In another embodiment, the terminal may also proactively send the first information. Alternatively, it can be understood that step S2103 is not executed and step S2104 can be directly executed.

[0215] In some embodiments, the first information is carried in at least one of the following:

[0216] (1) Msg5 message.

[0217] In some embodiments, each time the terminal enters the RRC connected state, the terminal sends the first information via a Msg5 message. Alternatively, the terminal sends availability indication information of the first information via a Msg5 message. The availability indication information may reuse existing report availability indication information or may be independently indicated. For example, the terminal sends availability indication information in a Msg5 message, and the availability indication information indicates that the terminal has the first information.

[0218] (2) Terminal information response message;

[0219] In some embodiments, the terminal receives an information request (UEinformationrequest) sent by a network device, and the terminal reports the first information to the network through a terminal information response (UEinformationresponse) message.
