[0072] To facilitate understanding of the technical solutions of the embodiments of the present application, the relevant technologies of the embodiments of the present application are described below. The following related technologies can be arbitrarily combined with the technical solutions of the embodiments of the present application as optional solutions, and they all belong to the protection scope of the embodiments of the present application.

[0073] Figure 2 FIG. 2 is a schematic flow chart of a method 200 for processing random access information according to an embodiment of the present application. The method can be applied to Figure 1 The system shown in the figure is not limited thereto. The method includes at least part of the following contents.

[0074] S210. The terminal sends a random access report, which includes slice information of the service related to the random access performed by the terminal.

[0075] In one example, the terminal needs to perform random access in scenarios such as sending uplink data, receiving downlink data, and updating tracking areas. There are two types of random access: collision-based and collision-free.

[0076] like Figure 3 As shown, in the collision-based random access process, the terminal uses a common random access preamble (RACH preamble) on a random access time-frequency resource (random access channel opportunity, RACH occasion) to send message 1 (msg1). Afterwards, the terminal uses RA (Random Access)-RNTI (Radio Network Temporary Identifier) ​​to monitor the network's PDCCH indication information about the random access response (RAR) on the physical downlink control channel (Physical Downlink Control Channel, PDCCH). When the PDCCH indication information about the RAR is found, the terminal will decode the RAR at the time-frequency position given by the PDCCH indication information. If the RAR includes the random access preamble information sent by the terminal, the terminal will then apply the information in the RAR corresponding to the random access preamble to send message 3 (msg3). For example, Figure 3 The subPDU in the subPDU indicates a subPDU (Protocol Data Unit), and Padding (opt) indicates that padding is optional. The terminal finds that the MACsubPDU3 format includes a subheader that matches its own preamble ID, and can subsequently use the content in the related MAC RAR to send msg3.

[0077] like Figure 4The figure shows an example of the specific contents included in the RAR. The RAR may include a timing advance command (TimingAdvance Command), an uplink grant (UL Grant), a temporary (Temporary) C-RNTI (Cell Radio Network Temporary Identifier, cell radio network temporary identifier), etc.

[0078] In msg3, which contains RRC commands such as Radio Resource Control (RRC) connection establishment request (RRCSetupRequest), the terminal needs to carry its own UE ID (identification). In the case of many terminals performing random access, other terminals may also send msg3 (carrying the terminal UE ID) at the time-frequency position indicated by the uplink grant (UL grant) to try to access the network. In this case, random access collisions will occur between terminals, and the network may only carry the ID of one of the UEs in message 4 (msg4) to allow it to access the network.

[0079] like Figure 5 As shown, it is an example of a random access process: Terminal 1 and Terminal 2 send message 1 (msg1) to a network device such as a gNB, which may include a preamble. The gNB returns a message 2 (msg2) to Terminal 1 and Terminal 2, which includes a random access response RAR, and the RAR includes an uplink grant (UL grant). Terminal 1 and Terminal 2 send a message 3 (msg3) to the network device, such as an RRC connection establishment request (RRCSetupRequest), which may include a terminal identifier, such as UEID#1 and UE ID#2. The gNB returns an RRC connection establishment result, which may include a terminal identifier of a successfully established connection, such as UE ID#1. At this time, the gNB may return a message of successful RRC connection establishment to Terminal 1, and a message of failed RRC connection establishment to Terminal 2.

[0080] Network slices can include a RAN (Radio Access Network) part and a CN (CoreNetwork) part. The communication network's support for network slicing depends on carrying data communications belonging to different slices by different PDU sessions. Different slices have different Network Slice Selection Assistance Information (NSSAI), as well as different transmission performance requirements such as reliability, transmission latency, transmission rate, etc. In actual applications, the network can carry eMBB (enhanced Mobile Broadband) and URLLC (Ultra-low latency communication) services on different PDU sessions. Each different PDU session can have multiple QoS (Quality of Service) flows.

[0081] For example, Figure 6 As shown, in specific communications, in the downlink direction, the NAS layer SDF (Service data flow) template of the core network classifies different data packets from the application layer, maps them to different QoS flows in different PDU sessions, and sends the QoS flows to the base station in different PDU sessions. Among them, the SDF template can be in the UPF (User Plane Function). The base station maps the QoS flow to different DRBs (Data Radio Bearers) on the air interface according to the ID information of the QoS flow and sends them to the terminal. Similarly, similar operations are also implemented for uplink data. Figure 6 The AN (Access Network) resources in the access network may include a radio bearer DRB. The QoS rules may include: mapping application layer data packets, such as UL data packets, to different QoS flows according to different QoS requirements, and applying different QoS flow markings. All data packets in the same QoS flow are marked with the same QoS flow ID.

[0082] In one example, random access resources can be divided based on SSB. In 5G NR, due to the large-scale application of beamforming technology, the terminal hopes to receive msg2 / msg4 replied by the network on a specific beam when performing random access to improve the information receiving power. In Rel-15 NR, the network allocates different random access resources (such as RO or random access preamble) to SSBs facing different directions, so that the terminal selects the random access resources corresponding to the SSB that meets its expectations to perform random access. When the network receives the msg1 from the terminal, it determines the SSB that the terminal expects to send downlink information based on the random access preamble and / or random access time-frequency resources (RACH ocassion) used by the terminal.

[0083] See also Figure 7 In one example, if the random access opportunity for SSB (e.g., ssb-perRACH-OccasionAndCB-PreamblesPerSSB) is set to 1:52 and Msg1-FDM is set to 2, the RO resources belonging to SSB 0 to SSB 3 are RO 0 to RO3, respectively. The preamble set applied to SSB 0 to SSB 3 is the same, for example, preamble 0 to 51. In addition, in this example, the SFN (System Frame Number) corresponding to SSB0 and SSB1 is 5, and the subframe is 9; the SFN corresponding to SSB2 and SSB3 is 9, and the subframe is 9.

[0084] See also Figure 8 In one example, if the random access opportunity for SSB (e.g., ssb-perRACH-OccasionAndCB-PreamblesPerSSB) is set to 4:13, Msg1-FDM is set to 1, SSB0 to SSB 4 share each RO, but apply different preamble sets. For example, the preamble set of SSB0 is preamble 0 to 12; the preamble set of SSB1 is preamble 16 to 28; the preamble set of SSB2 is preamble 32 to 44; and the preamble set of SSB3 is preamble 48 to 60. In addition, in this example, the SFN corresponding to SSB0 to SSB3 is 5 and the subframe is 9.

[0085] In order to prevent random access conflicts between terminals initiating random access for different slice services during the random access phase, random access resources can be divided according to different slices to achieve random access optimization.

[0086] The network may be unreasonable when configuring random access resources and related parameters, which may affect the random access experience of the terminal. The network requires the terminal to report to correct the configuration error. In this embodiment, the content that the terminal needs to report can be optimized.

[0087] like Fig. 9 As shown, it is an example of the reporting process. After the random access process, the network device, such as the gNB, may send an information request (Information Request) to the terminal, such as the UE, in which the random access report request is set to true (ra-ReportReq is set as true). The terminal may return an information response (InformationResponse) to the network device, which may include a random access report, such as ra-ReportList-r16.

[0088] The reported content may include the number of random access preambles sent in the random access attempt to a certain SSB (NumberOfPreamblesSentOnSSB), and an indication of whether a collision was encountered during each attempt. In an embodiment of the present application, slice information of the terminal and the service related to the random access performed may be added to the random access report. In this way, the network device can determine whether to adjust the random access resources corresponding to the slice information based on the number of random access preambles sent, the indication of the collision, the slice information, etc. For example, adjust the number of random access opportunities and / or the number of random access preambles, etc.

[0089] In one embodiment, in an embodiment of the present application, the slice information includes an identifier for identifying a network slice or an identifier of an object that has a corresponding relationship with the network slice.

[0090] Exemplarily, the identifier used to identify a network slice may be S-NSSAI (Single Network Slice Selection Assistance Information) that identifies a network slice.

[0091] For example, if the cell sorts each network slice ID from small to large and assigns index numbers ID1, 2, 3, 4..., the terminal may not report the value of the network slice when reporting, but report the index value of the ID.

[0092] In one implementation, in an embodiment of the present application, the slice information includes an index value of a slice identifier in a set of slice identifiers supported by a cell to which the terminal accesses.

[0093] Exemplarily, the slice identifier set supported by the cell accessed by the terminal may be an NSSAI set. The index value of a slice identifier in the slice identifier set may be the index value of a certain S-NSSAI in the NSSAI set.

[0094] In one embodiment, in an embodiment of the present application, the random access report also includes the number of preamble code transmissions attempted and / or preamble code collision information during a random access process associated with at least one synchronization signal block (SSB) or at least one channel state information reference signal (Channel-state informationReference Signal, CSI-RS).

[0095] Exemplarily, if the number of times the preamble code is attempted to be sent during the random access process is too many, for example, exceeding a certain threshold, it can be determined that the random access resources allocated to the slice for the terminal to perform random access are too few, and the random access resources corresponding to the slice can be increased.

[0096] In an embodiment of the present application, the random access report of the terminal includes slice information of the terminal and the service related to the random access performed, which can assist the network in allocating random access resources according to the slice information and optimize the allocation method of random access resources.

[0097] Fig.10 FIG. 3 is a schematic flow chart of a method 300 for processing random access information according to an embodiment of the present application. The method can be applied to Figure 1 The system shown in the figure is not limited thereto. The method includes at least part of the following contents.

[0098] S310. The network device receives a random access report, where the random access report includes slice information of a service related to the random access performed by the terminal;

[0099] S320. The network device determines whether to adjust the random access resources corresponding to the slice information based on the random access report.

[0100] In this embodiment, after the network device receives the random access report sent by one or more terminals, it can adjust the allocation ratio of the random access resources on different slices accordingly according to the content thereof.

[0101] For example, Fig.11 and Fig.12As shown, the number of preambles for slice 1 under each SSB is 10, and the number of preambles for slice 2 under each SSB is 40. If multiple terminals report that they have performed random access to slice 1 on cell 1, and finally access the network after trying to send 10+ random access preambles, then the base station providing service for cell 1 can know that the number of random access resources allocated to slice 1 is insufficient, and then optimize the number of random access resources. For example, the content of the random access report reported by multiple terminals includes: sending 10 preambles to SSB1, the service slice ID is 1, and the collision value of the first 9 preambles is set to true. In addition, the content of the random access report reported by multiple terminals includes: sending 2 preambles to SSB1, the service slice ID is 2, and the collision value of the first 1 preamble is set to true. The network device can increase the number of ROs or preambles of slice 1, and reduce the number of ROs or preambles of slice 2. For example, after optimization, the number of preambles for slice 1 under each SSB is 25, and the number of preambles for slice 2 under each SSB is 25.

[0102] In one embodiment, in an embodiment of the present application, the slice information includes an identifier for identifying a network slice or an identifier of an object that has a corresponding relationship with the network slice.

[0103] Exemplarily, the identifier used to identify a network slice may be an S-NSSAI that identifies a network slice.

[0104] In one implementation, in an embodiment of the present application, the slice information includes an index value of a slice identifier in a set of slice identifiers supported by a cell to which the terminal accesses.

[0105] Exemplarily, the slice identifier set supported by the cell accessed by the terminal may be an NSSAI set. The index value of a slice identifier in the slice identifier set may be the index value of a certain S-NSSAI in the NSSAI set.

[0106] In one implementation, in an embodiment of the present application, the random access report also includes the number of preamble code transmissions attempted in a random access process associated with at least one SSB or at least one CSI-RS and / or preamble code collision information.

[0107] Exemplarily, if the number of times the preamble code is attempted to be sent during the random access process is too many, for example, exceeding a certain threshold, the network device can determine that the random access resources allocated to the slice for the terminal to perform random access are too few, and can increase the random access resources corresponding to the slice.

[0108] In one implementation, in the embodiment of the present application, the network device determines, according to the random access report, whether to adjust the random access resource corresponding to the slice information, including:

[0109] The network device determines whether to adjust the number of preamble codes and / or the number of ROs corresponding to the slice information based on the number of times the preamble code is sent and / or the preamble code collision information.

[0111] In an embodiment of the present application, the method for processing random access information is a method for optimizing random access based on terminal feedback, which can optimize the network so that the sizes of random access resources allocated to different slices are different, so as to improve the overall random access experience of terminals in different slices, and the random access experience of terminals targeting key slices. The level of random access experience is mainly related to the low or high probability of access collision. Generally speaking, the more collisions there are, the more times the preamble needs to be resent, and the greater the delay of random access.
