Description

【Technical Field】 【0001】 The present disclosure relates to the field of communications, and particularly to a random access method, apparatus, and storage medium. 【Background Art】 【0002】 Network slicing can provide a complete end-to-end virtual network for specific users. By dividing network resources into multiple network slices, 5G (5th generation mobile networks) network slices can provide differentiated services for users with different service needs. Different service needs include, but are not limited to, latency, reliability, capacity, isolation, and other functions. The operator network can not only provide services for information consumption services characterized by "Best Effort transmission" of communication needs, but also meet the production control system services with certainty transmission as communication needs, and can allocate logically or physically isolated network resources to services with greatly different communication needs. 【0003】 One network slice can be composed of a RAN (Radio Access Network) part and a CN (Core Network) part. The realization of network slicing is determined by the principle that the traffic of different slices is processed by different PDU (Protocol Data Unit) sessions. The network can realize different network slices by scheduling and providing different L1 layer / L2 layer configurations. 【0004】 The random access process includes both conflicted and non-conflicted random access. In conflicted random access, the random access request resource (i.e., the resource used by MSG1) is not exclusive to one UE (User Equipment), meaning multiple users may initiate random access requests for the same time-domain and frequency-domain resource, and the relationship between the base station and the UE must be established through a conflict resolution process. In non-conflicted random access, the random access request resource is assigned to a UE specified by the base station, and the base station can uniquely identify this UE simply by recognizing the random access resource exclusive to that UE.

[Effects of the Invention] 【0014】 The technical solutions provided by the embodiments of this disclosure may include the following beneficial effects: 【0015】 In embodiments of this disclosure, a first random access resource to initiate random access can be determined based on slice information of a target network slice for initiating random access by user equipment and resource configuration information transmitted from the network side. The resource configuration information can include at least one of the following: a common random access resource, a designated random access resource corresponding to the target network slice, a two-step random access resource, a four-step random access resource, a two-step common random access resource, a four-step common random access resource, a two-step designated random access resource, and a four-step designated random access resource.

[Modes for carrying out the invention] 【0019】 Herein, exemplary embodiments are described in detail, and examples are shown in the drawings. Where the following description relates to the drawings, unless otherwise stated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present invention, which are described in detail in the appended claims. 【0020】 The terms used in this disclosure are for illustrative purposes only and are not intended to limit this disclosure. The singular forms “one kind,” “the said,” and “the said” used in this disclosure and the appended claims are also intended to include the plural form unless the context clearly indicates otherwise. The terms “and / or” as used herein refer to any combination or all possible combinations of at least one related enumeration. 【0021】 This disclosure may use terms such as First, Second, Third, etc., to describe various types of information, but it should be understood that this information should not be limited to these terms. These terms are simply used to distinguish the same type of information. For example, as long as it does not deviate from the scope of this disclosure, First Information may be called Second Information, and similarly, Second Information may be called First Information. Depending on the context, the word “if” as used herein may be interpreted as “when…” or “in the case of…” or “in response to a decision.” 【0022】 In embodiments of this disclosure, a UE using a particular slice service can initiate random access based on a common RACH (Random Access Channel) resource. Considering that multiple UEs initiate random access using a common RACH resource, the network is likely to become congested. 【0023】 To address this technical challenge, each network slice, or each network slice group, can be configured with a separate, designated RACH resource corresponding to that network slice. 【0024】 In the R16 (Release 16, version 16) phase, a two-step random access scheme is introduced, simplifying the random access process and reducing latency and signaling overhead by integrating Msg1 (Message 1) and Msg3 (Message 3) from the four-step random access scheme into MsgA (Message A), and integrating the two downlink channels Msg2 (Message 2) and Msg4 (Message 4) into a new MsgB (Message B). Before initiating random access, the UE (User Equipment) first determines the type of random access. 【0025】 The fallback mechanism is explained further. In the case of a two-step random access scheme, when the number of MsgA retransmissions reaches a certain threshold, a switch in the RA type is triggered, switching to a four-step random access scheme and repeated trial access of Msg1 is performed. This threshold is set by the base station in the system message. 【0026】 When the retransmission threshold is reached, the system switches to a 4-step random access scheme, and a fallback mechanism is also defined. The trigger condition for this fallback mechanism is that the preamble in MsgA is correctly detected. However, if demodulation of the PUSCH (Physical Uplink Shared Channel) message fails, the base station feeds back a fallbackRAR (fallback Random Access Response) message, similar to msg2 in the 4-step random access scheme used to schedule the transmission of Msg3. In this case, if retransmission occurs due to a failure to transmit msg3, the 2-step random access scheme must be used preferentially. 【0027】 Currently, when configuring random access resources, it is necessary to select an appropriate random access resource, initiate random access, and perform resource failback. How to implement resource failback needs further improvement. To address this issue, this disclosure provides the following random access scheme. 【0028】 The random access scheme provided by this disclosure is described below from the user equipment's perspective. 【0029】 Embodiments of this disclosure provide a random access method that can be used for user equipment (UE), and as shown in Figure 1, Figure 1 is a flowchart of a random access method shown by an exemplary embodiment, which may include the following steps 101-104. 【0030】 In step 101, resource configuration information transmitted from the base station is received. 【0031】 In embodiments of the present disclosure, the resource configuration information is used to configure at least one of the following: a common random access resource, a designated random access resource corresponding to at least one network slice, a two-step random access resource, a four-step random access resource, a two-step common random access resource, a four-step common random access resource, a two-step designated random access resource, and a four-step designated random access resource. 【0032】 A common random access resource is a random access resource shared among multiple UEs. In one possible example, these UEs include those that support network slicing and those that do not. That is, the common random access resource is a random access resource shared by UEs that support network slicing and those that do not. 【0033】 In another possible implementation, the multiple UEs include only those that support the network slicing feature. That is, the common random access resource is a shared random access resource among the UEs that support the network slicing feature. 【0034】 A specified random access resource corresponding to at least one network slice refers to a resource configured individually for each network slice to initiate random access by the UE on that network slice. For example, a specified random access resource corresponding to network slice 1 includes resource 1, a specified random access resource corresponding to network slice 2 includes resource 2, and so on. Alternatively, a specified random access resource corresponding to at least one network slice is a resource configured for each network slice group to initiate random access by the UE on each network slice within that network slice group. Each network slice group can contain two or more network slices. 【0035】 A 2-step random access resource refers to a resource available when the UE employs a 2-step random access method. Conversely, a 4-step random access resource refers to a resource available when the UE employs a 4-step random access method. 【0036】 A 2-step common random access resource refers to a composite resource that is shared among multiple UEs and can be used when employing a 2-step random access method. A 4-step common random access resource refers to a composite resource that is shared among multiple UEs and can be used when employing a 4-step random access method. 【0037】 A specified random access resource in two steps refers to a random access resource provided by the UE for a specific network slice, and is a composite resource usable when employing a two-step random access scheme. A specified random access resource in four steps refers to a random access resource provided by the UE for a specific network slice, and is a composite resource usable when employing a four-step random access scheme. 【0038】 Step 102 determines the slice information of the target network slice that will trigger random access. 【0039】 In the embodiments of this disclosure, the target network slice is a network slice for initiating random access by the user equipment, that is, the target network slice may be a network slice that is triggered by the user equipment to initiate random access. 【0040】 In step 103, a first random access resource is determined based at least on the resource configuration information and the slice information. 【0041】 Step 104 initiates random access based on the first random access resource. 【0042】 In the above embodiment, based on the slice information of the target network slice for initiating random access by the user equipment and the resource configuration information transmitted from the network side, a first random access resource to initiate random access can be determined from among the random access resources configured by the resource configuration information. This reduces the possibility of collisions occurring between random access between UEs using a particular slice service and other UEs, and improves the success rate of random access for UEs, thereby enabling UEs to complete random access quickly and obtain the desired slice service. 【0043】 In some selective embodiments, for step 101 above, the UE may receive resource configuration information in one of the following ways: 【0044】 In one possible implementation, during the UE's initial random access process, the UE can receive system messages that carry resource configuration information transmitted from the base station. 【0045】 In one possible implementation, the UE can receive a PDCCH (Physical Downlink Control Channel) instruction for a random access process triggered by a PDCCH instruction, which carries this resource configuration information. 【0046】 In one possible implementation, if the UE has already established an RRC connection with the base station, i.e., an RRC message transmitted from the base station triggers the UE to initiate random access, the UE can receive a radio resource control RRC message carrying the resource configuration information. 【0047】 Resource configuration information is used to configure at least one of the following: a common random access resource, a specified random access resource corresponding to at least one network slice, a two-step random access resource, a four-step random access resource, a two-step common random access resource, a four-step common random access resource, a two-step specified random access resource, and a four-step specified random access resource. 【0048】 In the above example, the UE can obtain resource configuration information in various ways, improving the success rate of random access and ensuring high availability. 【0049】 In some selective embodiments, the UE may employ, but is not limited to, one of the following methods to determine the slice information of the target network slice that triggers random access. 【0050】 In one possible embodiment, when a UE requests an AS (Access Stratum) layer at the NAS (Non-Access Stratum) layer to initiate an RRC connection, it can obtain slice information of the target network slice that is sent to the AS layer by the NAS layer. 【0051】 In another possible implementation, for random access where a page trigger exists on the network side, the UE can receive a page message carrying slice information of the target network slice transmitted from the base station. 【0052】 In another possible implementation, for a random access process triggered by a PDCCH instruction, the UE can receive a PDCCH instruction from the base station that carries slice information for this target network slice. 【0053】 In another possible implementation, if a logical channel identifier is associated with slice information, the UE can determine the logical channel in which the data to be transmitted resides, determine the slice information associated with this logical channel based on the channel identifier of this logical channel, and use this slice information as the slice information for the target network slice. Selectively, the association between logical channel identifiers and slice information may include, but is not limited to, different logical channel identifiers corresponding to the same or different slice information. 【0054】 In embodiments of this disclosure, the number of target network slices that trigger random access may be one or more, and this disclosure is not limited thereto. If there are multiple target network slices that trigger random access, a designated random access resource corresponding to a higher-priority target network slice can be determined as the first random access resource based on the priority of the target network slices. The priority order of different network slices can be determined by the NAS layer of the UE and provided to the AS layer. 【0055】 In embodiments of this disclosure, the slice information of a target network slice may include, but is not limited to, S-NSSAI (Single-Network Slice Selection Assistance Information), SST (Slice Service Type), SD (Slice Differentiator), slice index, slice identifier (or slice group identifier), and operator-defined access category. Of course, it may also include, but is not limited to, other information that uniquely identifies a slice. 【0056】 In the above embodiment, the UE can determine the slice information of the target network slice in a different manner, and then, based on the slice information of the target network slice and the received resource configuration information, determine a first random access resource from among the random access resources configured by the resource configuration information to initiate random access. By reducing the possibility of collisions occurring in the random access process and improving the success rate of the UE's random access, the UE can complete random access quickly and obtain the desired slice service. 【0057】 In some selective embodiments, the UE can determine the first random access resource in one of the following ways: 【0058】 In the first method, one random access resource is selected as the first random access resource from among the common random access resources and the specified random access resources corresponding to the target network slice. 【0059】 In one possible implementation, based on resource configuration information and slice information of the target network slice, it is determined that the base station has configured at least one specified random access resource corresponding to this target network slice. 【0060】 This allows the specified random access resource corresponding to the target network slice to be designated as a candidate resource. Furthermore, this candidate resource can be directly used as the first random access resource. In other words, the UE can initiate random access using the specified random access resource corresponding to the target network slice as the first random access resource. 【0061】 In one possible implementation, if a base station has not configured a specified random access resource corresponding to a target network slice based on resource configuration information and slice information of the target network slice, but has determined to configure a common random access resource, this common random access resource can be designated as a candidate resource. Furthermore, this candidate resource can be directly used as the first random access resource. 【0062】 In one possible implementation, based on the resource configuration information and the slice information, the base station determines that at least a designated random access resource corresponding to the target network slice and the common random access resource have been configured, the UE combines the signal quality to further determine which resource to select as a candidate resource, and further, the direct candidate resource can be designated as the first random access resource from which random access is initiated. 【0063】 The UE measures the signal quality, and if the signal quality is greater than the first threshold, it can designate a specified random access resource corresponding to the target network slice as a candidate resource. Furthermore, it designates the candidate resource as the first random access resource. 【0064】 Alternatively, the UE measures the signal quality of the channel, and if the signal quality is below a first threshold, it can designate a common random access resource as a candidate resource. Furthermore, the candidate resource is designated as the first random access resource. 【0065】 In the above embodiment, the first threshold can be used to determine whether the UE can select a specified random access resource corresponding to the target network slice and initiate random access as the first random access resource. The first threshold can be set by the base station. 【0066】 In one possible implementation, it can be set by a base station via a broadcasted first system message. Based on the first system message for setting the first threshold corresponding to at least one received network slice, the UE determines a first threshold which may be a first threshold corresponding to a target network slice set by the base station, or a first threshold which may be a first threshold corresponding to a group of network slices in which the target network slice set by the base station resides. 【0067】 Selectively, a base station may set the same or different first threshold for each network slice via a first system message, or a base station may set the same or different first threshold for each network slice group via a first system message, where each network slice group includes two or more network slices. 【0068】 For example, a base station can set a first threshold corresponding to network slice 1 as threshold 1 via a system message, and a first threshold corresponding to network slice 2 as threshold 2, and so on. Threshold 1 and threshold 2 may be the same or different. If the target network slice is network slice 1, the corresponding first threshold is threshold 1. 【0069】 Furthermore, for example, a base station can set a first threshold corresponding to network slice group 1 as threshold 3 via a system message, and a first threshold corresponding to network slice group 2 as threshold 4, and so on, where network slice group 1 includes network slice 1 and network slice 2, and network slice group 2 includes network slice 3 and network slice 4. If the target network slice is network slice 1, the corresponding first threshold is threshold 3. 【0070】 In another possible implementation, the base station may set a first threshold corresponding to at least one network slice in the UE via dedicated signaling, and the dedicated signaling may be an RRC (Radio Resource Control) message. That is, the base station may set a first threshold corresponding to at least one network slice in this UE via a first RRC message. 【0071】 Furthermore, if the base station sets a first threshold corresponding to at least one network slice for the UE via both system messages and RRC messages, the UE can use the first threshold set by the RRC message as a reference. 【0072】 In the above embodiment, the UE can select a designated random access resource or a common random access resource corresponding to the target network slice and initiate random access based on a first threshold and signal quality set by the base station, which is easy to implement and highly available. 【0073】 In the second method, one of the two-step random access resources and the four-step random access resource is selected as the first random access resource. 【0074】 In one possible implementation, if the base station configures only 2-step random access resources or only 4-step random access resources, the UE can directly select the 2-step or 4-step random access resources configured by the base station as candidate resources, and then directly select the candidate resources as the first random access resources. 【0075】 In one possible implementation, the base station configures a 2-step random access resource and also a 4-step random access resource, and when the UE determines that the signal quality is greater than a second threshold, the 2-step random access resource can be designated as a candidate resource. Furthermore, this candidate resource is directly designated as the first random access resource. 【0076】 In another possible implementation, the base station configures a 2-step random access resource and also a 4-step random access resource, and when the UE determines that the signal quality is below a second threshold, it can designate the 4-step random access resource as a candidate resource. Furthermore, this candidate resource is directly designated as the first random access resource. 【0077】 In one possible implementation, the second threshold may include a second threshold #1, specifically for determining whether the UE can select a 2-step common random access resource as the first random access resource and initiate random access. In this case, the second threshold #1 may be set by the base station via a second system message or a second RRC message, specifically, the second threshold #1 may be multiplexed with the reference signal receiving power threshold in the relevant technology, i.e., the legacy RSRP (Reference Signal Receiving Power) threshold, or may be set by the base station as another value different from the legacy RSRP threshold. 【0078】 For example, if a base station configures a 2-step common random access resource, a 4-step common random access resource, and a 4-step specified random access resource, the UE can select the 2-step common random access resource and initiate random access if the signal quality is greater than this second threshold #1. 【0079】 In one possible implementation, the second threshold may include a second threshold #2, which allows the UE to determine whether it can select a specified random access resource in two steps as the first random access resource and initiate random access. The second threshold #2 may also be set by the base station via a second system message or a second RRC message, or it may be multiplexed with the legacyRSRP threshold, or it may be set by the base station for each network slice or each network slice group, or it may be multiplexed with the first threshold, and this disclosure does not limit this. The second threshold #2 may be the same as or different from the second threshold #1, and this disclosure does not limit this. 【0080】 For example, if, based on resource configuration information, it is determined that the base station has configured a 2-step specified random access resource, a 4-step common random access resource, and a 4-step specified random access resource, and the signal quality is greater than the second threshold #2, then the 2-step specified random access resource can be selected and designated as the first random access resource. 【0081】 In one possible implementation, the base station can set the above second threshold via a broadcasted second system message, which includes, but is not limited to, at least one of second threshold #1 and second threshold #2. 【0082】 The second system message may be the same as or different from the first system message, and this disclosure is not limited thereto. 【0083】 In another possible implementation, the base station may set the above-described second threshold to the UE via dedicated signaling, which includes, but is not limited to, at least one of the second threshold #1 and the second threshold #2, and the dedicated signaling may be a second RRC message. The second RRC message may be the same as, or different from, the first RRC message, and this disclosure is not limited thereto. 【0084】 Similarly, if the base station sets a second threshold for the UE via both system messages and RRC messages, the UE can comply with the second threshold set by the RRC message. 【0085】 In the above embodiment, the UE can initiate random access by selecting either a 2-step random access resource or a 4-step access resource based on a second threshold set by the base station and the measured signal quality, which is easy to implement and highly available. 【0086】 The two methods described above may exist independently of each other. If they exist independently, and the candidate resource includes any of the common random access resource, the designated random access resource corresponding to the target network slice, the two-step random access resource, or the four-step random access resource, then the candidate resource is equivalent to directly making the first random access resource. 【0087】 In the embodiments of this disclosure, the two embodiments may be combined, i.e., a third embodiment as described below. In the case of a combination, there is no distinction in the priority of the combinations. That is, candidate resources can be determined first using the first method described above, and then a first random access resource can be determined from among the candidate resources based on the second method. Alternatively, candidate resources can be determined first using the second method described above, and then a first random access resource can be determined from among the candidate resources based on the first method, and the specific methods are as follows. 【0088】 In the third method, the first random access resource can be determined after combining the first and second methods described above. 【0089】 In one possible embodiment, first, a common random access resource or a designated random access resource corresponding to the target network slice can be selected as a candidate resource according to the first method described above, and then, by combining the second method described above, a two-step random access resource or a four-step random access resource can be selected from the candidate resources, and finally, a composite resource can be selected as the first random access resource. 【0090】 In one possible implementation, a two-step random access resource or a four-step random access resource may be selected as a candidate resource according to the second method described above, and then the first method described above may be combined to select a common random access resource or a specified random access resource corresponding to a target network slice from among the candidate resources, and finally a single composite resource may be selected as the first random access resource. 【0091】 The following explanations are based on different combinations. 【0092】 In the first case, a common random access resource is selected as a candidate resource according to the first method, and then a 2-step random access resource or a 4-step random access resource is selected according to the second method described above, and finally the 2-step common random access resource or the 4-step common random access resource is designated as the first random access resource. 【0093】 Specifically, after selecting a common random access resource as a candidate resource, if it is determined that only a 2-step common random access resource has been configured by the base station based on the resource configuration information, the UE will directly designate the 2-step common random access resource as the first random access resource. 【0094】 Alternatively, after selecting a common random access resource as a candidate resource, if the UE determines, based on the resource configuration information, that only a 4-step common random access resource has been configured by the base station, the UE will directly designate the 4-step common random access resource as the first random access resource. 【0095】 Alternatively, after selecting a common random access resource as a candidate resource, if the UE determines, based on the resource configuration information, that the base station has configured a 2-step common random access resource and a 4-step common random access resource, the UE may select the 2-step common random access resource as the first random access resource if the channel signal quality is greater than the second threshold #1. If the channel signal quality is less than or equal to the second threshold #1, the UE selects the 4-step common random access resource as the first random access resource. The second threshold #1 is used by the UE to determine whether it can select the 2-step common random access resource as the first random access resource and initiate random access. The second threshold #1 may also be set by the base station via a second system message or a second RRC message, specifically by multiplexing legacy RSRP thresholds, or by setting it as another value different from the legacy RSRP threshold. 【0096】 In the second case, first, a designated random access resource corresponding to the target network slice is determined to be a candidate resource according to the first method described above. Furthermore, by combining the second method described above, a 2-step random access resource or a 4-step random access resource can be selected from the candidate resources, and finally, the designated 2-step random access resource or the designated 4-step random access resource can be designated as the first random access resource. 【0097】 Specifically, after selecting random access resources corresponding to the target network slice as candidate resources, if it is determined that the base station has configured only a specified 2-step or 4-step random access resource based on the resource configuration information, the UE can directly designate the specified 2-step or 4-step random access resource as the first random access resource. 【0098】 Alternatively, if, after selecting a random access resource corresponding to a target network slice as a candidate resource, the UE determines, based on the resource configuration information, that the base station has configured a specified 2-step random access resource and a specified 4-step random access resource, the UE may designate the specified 2-step random access resource as the first random access resource if the signal quality is greater than the second threshold #2. If the signal quality is less than or equal to the second threshold #2, the UE selects the specified 4-step random access resource as the first random access resource. The second threshold #2 is for the UE to determine whether it can select the specified 2-step random access resource as the first random access resource and initiate random access. The threshold may also be set by the base station via a second system message or a second RRC message, specifically by multiplexing legacyRSRP thresholds, or by the base station for each network slice or each network slice group, or by multiplexing the first threshold, and this disclosure is not limited thereto. The second threshold #2 may be the same as or different from the second threshold #1, and this disclosure is not limited thereto. 【0099】 In the third case, first, a two-step random access resource can be selected as a candidate resource according to the second method described above, and then, by combining it with the first method described above, a common random access resource or a specified random access resource corresponding to a target network slice can be selected from the candidate resources, and finally, the two-step common random access resource or the specified two-step random access resource can be selected as the first random access resource. 【0100】 Specifically, if a base station configures only a two-step common random access resource and does not configure the specified two-step random access resource, the UE can directly select the two-step common random access resource as the first random access resource. 【0101】 Alternatively, if the base station has configured at least two specified random access resources, it will directly select two specified random access resources and make them the first random access resource. 【0102】 Alternatively, if the base station configures both a 2-step common random access resource and a 2-step designated random access resource, the UE will preferentially select the 2-step designated random access resource and make it the first random access resource. 【0103】 Alternatively, if the base station configures a 2-step common random access resource and a 2-step designated random access resource, the UE selects the 2-step designated random access resource as the first random access resource if the channel quality is greater than the second threshold #2. Otherwise, it selects the 2-step common random access resource as the first random access resource. The second threshold #2 is for the UE to determine whether it can initiate random access by selecting the 2-step designated random access resource as the first random access resource. The second threshold #2 may also be configured by the base station via a second system message or a second RRC message, and the second threshold may be multiplexed with legacy RSRP thresholds, or configured by the base station for each network slice or network slice group, or may be multiplexed with the first threshold, but this disclosure does not limit this. 【0104】 In the fourth case, first, a 4-step random access resource can be selected as a candidate resource according to the second method described above, and then, by combining it with the first method described above, a common random access resource or a specified random access resource corresponding to a target network slice can be selected from the candidate resources, and finally, the 4-step common random access resource or the specified 4-step random access resource can be selected as the first random access resource. 【0105】 Specifically, if the base station configures only a 4-step common random access resource and does not configure the specified 4-step random access resource, the UE can select the 4-step common random access resource as the first random access resource. 【0106】 Alternatively, if the base station has configured at least four specified random access resources, it may directly select four specified random access resources as the first random access resource. 【0107】 Alternatively, if the base station configures a 4-step common random access resource and a 4-step designated random access resource, the UE selects the 4-step designated random access resource as the first random access resource if the channel quality is greater than a first threshold. If the channel quality is less than or equal to the first threshold, the UE selects the 4-step common random access resource as the first random access resource. Here, the threshold used by the UE to determine whether or not the 4-step designated random access resource can be selected is a direct multiplexing of the first threshold. Of course, it can be set to any other value different from the first threshold, but this disclosure does not limit this. 【0108】 In the above embodiment, based on one of the above methods, a first random access resource to initiate random access is determined from among at least one random access resource configured by the resource configuration information, thereby enabling rapid completion of random access and acquisition of the desired slice service, resulting in high availability. 【0109】 In some selective embodiments, embodiments of the present disclosure provide a random access method that can be used for user equipment (UE), and as shown in Figure 2, Figure 2 is a flowchart of a random access method shown by an exemplary embodiment, which may include the following steps 201-205. 【0110】 In step 201, resource configuration information transmitted from the base station is received. 【0111】 Step 202 determines the slice information of the target network slice that will trigger random access. 【0112】 In step 203, a first random access resource is determined based at least on the resource configuration information and the slice information. 【0113】 Step 204 initiates random access based on the first random access resource. 【0114】 In step 205, resource fallback is not performed in response to the fulfillment of a pre-configured fallback condition. 【0115】 In one possible implementation, when random access is initiated to a designated random access resource corresponding to the target network slice as the first random access resource, the pre-configured fallback condition is met and resource fallback is not performed. 【0116】 In another possible implementation, when random access is initiated to the common random access resource as the first random access resource, the pre-configured fallback condition is met and resource fallback is not performed. 【0117】 The pre-configured fallback conditions include any of the following: the number of failures to initiate random access based on the first random access resource reaches a first fallback threshold; the first fallback timer expires; or a random access resource fallback instruction message corresponding to the target network slice is received. 【0118】 In the above embodiment, if the pre-set fallback conditions are met, fallback does not need to be performed, resulting in high availability. 【0119】 In some selective embodiments, embodiments of the present disclosure provide a random access method that can be used for user equipment (UE), and as shown in Figure 3, Figure 3 is a flowchart of a random access method shown by an exemplary embodiment, which may include the following steps 301-306. 【0120】 In step 301, resource configuration information transmitted from the base station is received. 【0121】 Step 302 determines the slice information of the target network slice that will trigger random access. 【0122】 In step 303, a first random access resource is determined based at least on the resource configuration information and the slice information. 【0123】 Step 304 initiates random access based on the first random access resource. 【0124】 In step 305, a second random access resource to which to fall back is determined in response to the fulfillment of a pre-configured fallback condition. 【0125】 Random access is resumed based on the second random access resource. Pre-configured fallback conditions include any of the following: the number of failures to initiate random access based on the first random access resource reaches a first fallback threshold; the first fallback timer expires; or a random access resource fallback instruction message corresponding to the target network slice is received. 【0126】 In step 306, random access is resumed based on the second random access resource. 【0127】 In the above embodiment, if the first random access resource is hit multiple times, the user equipment can perform resource fallback and resume random access based on the second random access resource that was used as the fallback. This prevents the UE from starting random access on the first random access resource and failing until the maximum number of random access attempts is reached, thereby improving the success rate of the UE's random access. 【0128】 In some selective embodiments, if the UE, after initiating random access based on a specific random access resource, determines that a pre-configured fallback condition has been met, it may process the situation in one of the following ways: In the first method, resource fallback is not performed. The second method employs resource fallback. 【0129】 Accordingly, the UE can determine which random access resource to fall back to and resume random access based on the random access resource to fall back to. 【0130】 The random access resource that initiates random access is different from the random access resource to which it should fall back. For example, if the UE initiates random access based on a first random access resource and determines that a pre-configured fallback condition has been met, the UE resumes random access based on a second random access resource to which it has fallen back. The second random access resource is different from the first random access resource. 【0131】 In the above embodiment, the UE can avoid the problem of a high random access failure rate caused by repeatedly using the first random access resource to continuously initiate random access, by not performing resource fallback when a preset fallback condition is met, or by restarting random access based on the second random access resource that has been fallen back to. 【0132】 In some selective embodiments, if a pre-configured fallback condition is met again while the UE is resuming random access based on a second random access resource, the UE may choose not to perform another fallback, or it may continue the fallback, in which case it must determine a third random access resource to which it fell back and resume random access based on the third random access resource. 【0133】 The process for determining the third random access resource is the same as the process for determining the second random access resource, and will not be explained here. The third random access resource is different from the second random access resource. 【0134】 In some selective embodiments, the two cases described above can be combined, namely, no resource fallback is performed in response to the fulfillment of the pre-set fallback condition when restarting random access based on the second random access resource. Alternatively, in response to the fulfillment of the pre-set fallback condition when restarting random access based on the second random access resource, a third random access resource to which to fallback is determined, and random access is restarted based on the third random access resource. The process for determining the third random access resource is similar to the process for determining the second random access resource and will be described together in subsequent embodiments, but will not be described here. 【0135】 In one possible implementation, a pre-configured fallback condition may include the number of failures required to initiate random access based on the first random access resource reaching a first fallback threshold. Herein, the first fallback threshold may be used to indicate the cumulative number of failures required to initiate random access based on the first random access resource before falling back to the second random access resource to perform random access. 【0136】 For example, if the first fallback count threshold is N1, the number of failures in which the UE attempts to initiate random access based on the first random access resource reaches N1, and the UE determines that the pre-configured fallback condition has been met, it can fall back to the second random access resource and resume random access. 【0137】 In embodiments of this disclosure, the first fallback count threshold may be set by the base station. In one possible implementation, it can be set by the base station via a broadcasted third system message. Optionally, the first fallback count threshold can be multiplexed with the fallback count threshold, i.e., the legacy threshold, in the relevant mechanism. Alternatively, it can be set by the base station for each network slice or group of network slices via a third system message. 【0138】 In one possible implementation, it can be set by the base station via a third system message. Similarly, the first fallback count threshold can be multiplexed with the fallback count threshold, i.e., the legacy threshold, in the relevant mechanism. Alternatively, it can be set by the base station for each network slice or network slice group via a third RRC message. 【0139】 In another possible implementation, a pre-configured fallback condition may include the expiration of a first fallback timer. The first fallback timer is used to indicate a cumulative time length that allows random access to be initiated based on the first random access resource before falling back to the second random access resource and performing random access. 【0140】 For example, if the duration of the first fallback timer is t1, the cumulative duration for the UE to initiate random access based on the first random access resource reaches t1, and the UE determines that the pre-configured fallback condition has been met, allowing it to fall back to the second random access resource and resume random access. 【0141】 In embodiments of this disclosure, the first fallback timer may be set by the base station. In one possible implementation, it may be set by the base station via a broadcasted fourth system message. In another possible implementation, the pre-configured fallback condition may include receiving a random access resource fallback instruction message corresponding to the target network slice. 【0142】 In embodiments of the present disclosure, the UE determines that a pre-configured fallback condition has been met based on a random access resource fallback instruction message corresponding to this target network slice sent from the network side, and thereby can fall back to a second random access resource and resume random access. 【0143】 The pre-configured fallback conditions may include any one or more combinations of the above, and other possible pre-configured fallback conditions should fall within the scope of protection of this disclosure. 【0144】 In the above embodiment, in addition to satisfying the above-mentioned pre-configured fallback conditions, the UE can perform resource fallback and resume random access on the second random access resource to which it fell back, thereby improving the success rate of random access. 【0145】 In some selective embodiments, a random access fallback instruction message may be used to set at least one of a second fallback count threshold and a second fallback timer. The second fallback count threshold is used to indicate the number of failures that allow random access to be initiated based on the second random access resource before falling back from the second random access resource to the first random access resource, and the second fallback timer is used to indicate the cumulative time length that allows random access to be initiated based on the second random access resource before falling back from the second random access resource to the first random access resource to perform random access. 【0146】 For example, if the second fallback threshold is N2, the number of times the UE has fallen back from the first random access resource to the second random access resource and resumed random access has reached N2, and the total number of times random access has been initiated so far has not reached the preamble TransMax (maximum number of random accesses), then the UE can fall back to the first random access resource again and initiate random access. 【0147】 If the first random access resource is a resource in the specified random access resource spool corresponding to the target network slice, the UE can preferentially fall back to a resource in the specified random access resource spool corresponding to the target network slice. The UE will continue to perform resource fallback until the pre-configured fallback conditions are met again. Alternatively, the UE may fall back to a resource in the specified random access resource spool corresponding to the target network slice, and if the total number of random access attempts reaches the maximum number of random access attempts, the UE can report a random access failure message to the upper layer. 【0148】 Furthermore, for example, if the timing duration of the second fallback timer is t2, and the cumulative time duration over which the UE falls back from the first random access resource to the second random access resource and initiates random access reaches t2 times, and the total number of random access attempts currently made has not reached the maximum number of random access attempts, the UE can fall back to the first random access resource again and initiate random access. In other words, the UE can preferentially select a resource in the specified random access resource spool corresponding to the target network slice and initiate random access again. The UE will continue to perform resource fallbacks until the pre-configured fallback conditions are met again. Alternatively, the UE may fall back to a resource in the specified random access resource spool corresponding to the target network slice, and if the total number of random access attempts reaches the maximum number of random access attempts, the UE can report a random access failure message to the upper layer. 【0149】 In the above embodiment, after the UE falls back to the second access resource, it can start random access on the second random access resource until the maximum number of random accesses is reached, thus avoiding the problem of random access failures. After the second random access resource has been hit at least once, the UE can fall back to the first random access resource again and start random access, improving the success rate of the UE's random access. 【0150】 In some selective embodiments, if the random access resource fallback instruction message does not set a second fallback count threshold and does not set a second fallback timer, the UE may, after failing to perform one random access by falling back from the first random access resource to the second random access resource, and if the total number of random accesses currently in progress has not reached the maximum number of random accesses, fall back to the first random access resource again to resume random access. The first random access resource may include resources in a specified random access resource spool corresponding to the target network slice. 【0151】 In the above embodiment, after the UE falls back to the second access resource, it can start random access on the second random access resource until the maximum number of random accesses is reached, thus avoiding the problem of random access failures. After the second random access resource is hit once, the UE can fall back to the first random access resource again and start random access, improving the success rate of the UE's random access. 【0152】 In some selective embodiments, the random access resource fallback instruction message may carry a fallbackFactor, which selectively may be a fallback probability value to enable the UE to implement probabilistic fallback. 【0153】 In embodiments of the present disclosure, after receiving a random access resource fallback instruction message, the UE can generate a random number, thereby determining whether a resource fallback is necessary based on the generated random number and the fallback probability value carried in the random access resource fallback instruction message. If it is determined that a resource fallback is necessary, random access can be resumed based on a second random access resource that has been fallen back. 【0154】 In one possible implementation, the UE can, but is not limited to, randomly generate random numbers that satisfy a uniform distribution, and these random numbers are, but are not limited to, the range [0,1]. If the generated random number is less than this fallback probability value, the UE performs a random access resource fallback; if the generated random number is greater than or equal to this fallback probability value, it does not have to perform a random access resource fallback. 【0155】 In another possible embodiment, the UE can generate random numbers that satisfy a different distribution, and if the generated random number is greater than this fallback probability value, the UE performs a random access resource fallback; if the generated random number is less than or equal to the fallback probability value, the UE does not have to perform a resource fallback. 【0156】 In the above embodiment, the UE can decide whether or not to perform a resource fallback based on the fallback probability value and generated random number carried in the random access resource fallback instruction message, and can further resume random access based on the second random access resource to which it has fallen. This prevents the UE from starting random access on the first random access resource and failing until the maximum number of random accesses is reached, thus achieving the purpose of the UE performing a probability fallback and improving the success rate of the UE's random access. 【0157】 In some selective embodiments, if a random access resource fallback instruction message does not carry a fallbackFactor, all UEs that receive this random access resource fallback instruction message perform resource fallback. 【0158】 In some selective embodiments, the base station may carry a random access resource fallback instruction message corresponding to the target network slice in the random access response message. Alternatively, the base station may carry a random access resource fallback instruction message corresponding to the target network slice in the fifth RRC message. 【0159】 In some selective embodiments, the UE can determine a second random access resource in a corresponding manner for any of the following cases: 【0160】 In the first case, if the first random access resource is a designated 2-step random access resource, the UE may choose to fall back to the designated 4-step random access resource and resume random access if initiating random access on the designated 2-step random access resource satisfies at least one of the above-mentioned pre-configured fallback conditions, and the UE determines, based on the resource configuration information and the slice information, that the base station has configured the designated 4-step random access resource. In other words, the designated 4-step random access resource becomes the second random access resource. 【0161】 In the second case, if the first random access resource is a specified 2-step random access resource, the UE can set information and signal quality based on the resource if initiating random access on the specified 2-step random access resource satisfies at least one of the above-mentioned pre-configured fallback conditions, and the base station determines that the common random access resource has been configured based on the resource configuration information and the slice information. A second random access resource is determined from among the common random access resources. That is, a 2-step common random access resource or a 4-step common random access resource is selected as the second random access resource. 【0162】 In the third case, if the first random access resource is a specified 2-step random access resource, the UE may, after determining that it can fall back to the common random access resource and resume random access based on the first instruction information transmitted from the base station, set the information and signal quality based on the resource, if the base station determines that the common random access resource has been set based on the resource setting information and the slice information, then set the information and signal quality based on the resource. From among the common random access resources, a second random access resource is determined. That is, a 2-step common random access resource or a 4-step common random access resource is selected as the second random access resource. 【0163】 In one possible implementation, a base station configures a two-step common random access resource, and if the signal quality is greater than a third threshold, the UE can make the two-step common random access resource the second random access resource. The third threshold is used by the UE to determine whether it can fall back to the two-step common random access resource and resume random access. 【0164】 Specifically, a base station can set a third threshold corresponding to at least one network slice via a fifth system message or a sixth RRC message. The third threshold may be a multiplexing of legacy RSRP thresholds or may be set separately by the base station. Similarly, a base station can set the same or different third thresholds for each network slice, or a base station can set the same or different third thresholds for each network slice group. 【0165】 In another possible implementation, the base station has configured a 2-step common random access resource and a 4-step common random access resource, but if the signal quality is below a third threshold, the UE can make the designated 4-step random access resource the second random access resource. 【0166】 In another possible implementation, the base station does not configure a 4-step common random access resource, and the UE does not need to fall back if the signal quality is below the third threshold. 【0167】 The embodiments described above may exist independently or in combination, and this application is not limited thereto. 【0168】 In the fourth case, the first random access resource belongs to the common random access resource, meaning that the UE does not need to fall back if it satisfies the pre-configured fallback conditions when initiating random access with the common random access resource. 【0169】 Alternatively, based on the resource setting information and the slice information, it can be determined that the base station has set up the four-step common random access resource, and the four-step common random access resource can be designated as the second random access resource. 【0170】 Alternatively, if it is determined that the base station has configured a designated random access resource corresponding to the target network slice based on the resource configuration information and the slice information, the second random access resource can be determined from among the designated random access resources corresponding to the target network slice based on the resource configuration information and signal quality. 【0171】 Alternatively, if it is determined that the base station has configured a designated random access resource corresponding to the target network slice based on the resource configuration information and the slice information, and it is determined that random access can be resumed by falling back to the designated random access resource corresponding to the target network slice based on network instructions, the second random access resource is determined from among the designated random access resources corresponding to the target network slice based on the resource configuration information and signal quality. 【0172】 In one possible implementation, if it is determined that the base station has configured the specified random access resource for step 4 based on the resource configuration information, the specified random access resource for step 4 can be directly designated as the second random access resource. 【0173】 In one possible implementation, based on the resource configuration information, if the base station determines that the specified random access resource of step 4 has been configured and the signal quality is greater than the fourth threshold, the specified random access resource of step 4 can be designated as the second random access resource. The fourth threshold is used to determine whether random access can be resumed by falling back to the random access resource designated by the UE. The fourth threshold may be configured by the base station via a sixth system message or a seventh RRC message, and the fourth threshold may be multiplexed with the legacy RSRP threshold or configured separately by the base station. Similarly, the base station may configure the same or different fourth thresholds for each network slice, or the base station may configure the same or different fourth thresholds for each network slice group. 【0174】 To illustrate the above with a simple example, the UE can determine a second random access resource based on any one or more combinations of the above, or, if restarting random access based on the second random access resource again satisfies a pre-set fallback condition, it will not fall back, or it will determine a third random access resource based on a similar method, thereby allowing the UE to continue initiating random access with the same random access resource until the maximum number of random accesses is reached, thus avoiding random access failures and improving the success rate of the UE's random access. 【0175】 Furthermore, if the thresholds described above are to be set by the base station via both system messages and RRC, it should be further explained that the UE may use the thresholds set based on the RRC messages as a reference. 【0176】 The random access scheme provided by this disclosure will be described below from the base station's perspective. 【0177】 Embodiments of this disclosure provide a random access method that can be used for a base station, and as shown in Figure 4, Figure 4 is a flowchart of a random access method shown by an exemplary embodiment, the method may include the following steps 401. 【0178】 In step 401, the resource configuration information is sent to the User Equipment (UE). 【0179】 In embodiments of the present disclosure, the resource configuration information is used to configure at least one of the following: a common random access resource, a designated random access resource corresponding to at least one network slice, a two-step random access resource, a four-step random access resource, a two-step common random access resource, a four-step common random access resource, a two-step designated random access resource, and a four-step designated random access resource. 【0180】 In the above embodiment, the base station can configure the UE with at least one of the above resources using resource configuration information so that the UE can determine a first random access resource and initiate random access, thus ensuring high availability. 【0181】 In some selective embodiments, the base station may set a first threshold corresponding to at least one network slice via a system message or RRC message. The first threshold may be used to determine whether the UE can select a specified random access resource corresponding to a target network slice and initiate random access as the first random access resource. 【0182】 Specifically, the base station can set a first threshold via a first system message or a first RRC message. 【0183】 In some selective embodiments, the base station may set a second threshold corresponding to at least one network slice via a system message or RRC message. The second threshold may be used to determine whether the UE can select a two-step random access resource and initiate random access as a first random access resource. 【0184】 Specifically, the base station can set a second threshold via a second system message or a second RRC message. In one possible implementation, the second threshold may include a second threshold #1, specifically for determining whether a two-step common random access resource can be selected by the UE. In this case, the second threshold #1 may be set by the base station via a second system message or a second RRC message, specifically, the second threshold #1 can multiplex a reference signal reception power threshold in the relevant technology, i.e., a legacy RSRP threshold. 【0185】 In one possible implementation, the second threshold may include a second threshold #2, which allows the UE to determine whether it can select a specified random access resource in two steps as the first random access resource and initiate random access. The second threshold #2 may also be set by the base station via a second system message or a second RRC message, or it may be multiplexed with the legacyRSRP threshold, or it may be set by the base station for each network slice or each network slice group, or it may be multiplexed with the first threshold, and this disclosure does not limit this. The second threshold #2 may be the same as or different from the second threshold #1, and this disclosure does not limit this. 【0186】 In some selective embodiments, the base station can set a first fallback count threshold corresponding to at least one network slice via a system message or RRC message. Herein, the first fallback count threshold can be used to indicate the cumulative number of failures that allows initiating random access based on the first random access resource before falling back to the second random access resource and performing random access. 【0187】 Specifically, the base station can set this first fallback count threshold via a third system message or a third RRC message. The first fallback count threshold may be multiplexed with the legacy threshold or may be set separately by the base station. 【0188】 In some selective embodiments, the base station may set a first fallback timer via a system message or RRC message. The first fallback timer is used to indicate a cumulative time length that allows random access to be initiated based on the first random access resource before falling back to the second random access resource and performing random access. 【0189】 Specifically, the base station can set this first fallback timer via a fourth system message or a fourth RRC message. 【0190】 In some selective embodiments, the base station may carry a random access resource fallback instruction corresponding to the target network slice via a random access response message or a fifth RRC message. 【0191】 In some selective embodiments, the base station can, via first instruction information, instruct the UE to fall back to a common random access resource and resume random access. 【0192】 In some selective embodiments, the base station can, via second instruction information, instruct the UE to fall back to a designated random access resource corresponding to the target network slice and resume random access. 【0193】 In some selective embodiments, the base station may set a third threshold via a system message or RRC message. The third threshold is used by the UE to determine whether random access can be resumed by falling back to a two-step common random access resource. 【0194】 Specifically, the base station can set the third threshold via a fifth system message or a sixth RRC message. The third threshold may be a multiplexed legacy RSRP threshold or may be set separately by the base station. 【0195】 In some selective embodiments, the base station may set a fourth threshold via a system message or RRC message. The fourth threshold is used to determine whether random access can be resumed by falling back to a random access resource specified by the UE. 【0196】 Specifically, the base station can set the third threshold via a sixth system message or a seventh RRC message. The fourth threshold may be a multiplexed legacy RSRP threshold, or it may be set by the base station for each network slice or each network slice group. 【0197】 The above system messages may be the same or different, and the RRC messages may also be the same or different, but this disclosure is not limited to these. 【0198】 The following further examples illustrate the random access process of this application by combining different resource configuration information. 【0199】 In the first case, for Case 3 agreed upon in the protocol, the base station configures the UE with four specified random access resources and two common random access resources based on resource configuration information. In related technologies, when initiating random access, the four specified random access resources are always selected to initiate random access. If pre-configured fallback conditions are met, there is no fallback, or the system falls back to the common random access resources. 【0200】 According to the random access scheme provided in this application, random access can be initiated by selecting a designated random access resource in four steps or a common random access resource in two steps, according to the above scheme. Resource fallback includes the following two: 【0201】 In the first case, initiating random access on a common random access resource in four steps satisfies a pre-configured fallback condition. Fallback is not required. 【0202】 In the second case, if initiating random access with a two-step common random access resource satisfies a pre-configured fallback condition, the following approach can be adopted. 【0203】 Option 1: Do not use fallback. 【0204】 Option 2: Fall back to the specified random access resource in step 4 and resume random access. 【0205】 Option 3: If the signal quality is greater than the fourth threshold, fall back to the specified random access resource in step 4 and resume random access; otherwise, do not fall back. 【0206】 Option 4: Based on the second instruction information transmitted from the base station, if it is determined that it is possible to fall back to a designated random access resource corresponding to the target network slice, random access is resumed by falling back to the designated random access resource in step 4; otherwise, no fallback is performed. 【0207】 Option 5: Based on the second instruction information transmitted from the base station, if it is determined that a fallback to a designated random access resource corresponding to the target network slice is possible and the signal quality is greater than the fourth threshold, random access is resumed by falling back to the designated random access resource in step 4; otherwise, no fallback is performed. 【0208】 In the second case, for Case 6 agreed upon in the protocol, the base station configures the UE with two specified random access resources and two common random access resources based on resource configuration information. In related technologies, when initiating random access, the two specified random access resources are always selected to initiate random access. If pre-configured fallback conditions are met, there is no fallback, or the system falls back to the common random access resources. 【0209】 According to the random access scheme provided in this application, random access can be initiated by selecting either a two-step designated random access resource or a two-step common random access resource according to the above scheme. In the case of resource fallback, it is generally possible to fall back from a two-step designated random access resource to a two-step common random access resource, and below, the example of initiating random access with a two-step designated random access resource is explained. 【0210】 Option 1: Do not use fallback. 【0211】 Option 2: Fall back to a specified random access resource in two steps and resume random access. 【0212】 Option 3: Based on the first instruction information transmitted from the base station, if it is determined that a fallback to a common random access resource is possible, random access is resumed by falling back to the specified random access resource in two steps; otherwise, no fallback is performed. 【0213】 In the third case, corresponding to Case 8, the base station configures the UE with a specified 2-step random access resource, a common 2-step random access resource, and a common 4-step random access resource based on resource configuration information. In related technologies, when initiating random access, the specified 4-step random access resource is always selected to initiate random access. If a pre-configured fallback condition is met, the system falls back from the specified 4-step random access resource to the common 4-step random access resource. 【0214】 According to the random access scheme provided in this application, random access can be initiated by selecting one of the following: a two-step designated random access resource, a two-step common random access resource, or a four-step common random access resource, in accordance with the above scheme.

In related technologies, there is currently no method for initiating random access and performing resource fallback. 【0227】 According to the random access scheme provided in this application, one can choose to initiate random access. In the case of resource fallback, this includes the following three options: 【0228】 In the first case, initiating random access with a two-step common random access resource satisfies a pre-configured fallback condition. 【0229】 Option 1: Do not use fallback. 【0230】 Option 2: Fall back to the specified random access resource in step 4 and resume random access. 【0231】 Option 3: Fall back to a common random access resource in step 2 and resume random access. 【0232】 Option 4: Based on the first instruction information transmitted from the base station, if it is determined that a fallback to a common random access resource is possible, random access is resumed by falling back to a 2-step common random access resource; otherwise, no fallback is performed. 【0233】 In the second case, initiating random access with a specified random access resource in 4 steps satisfies a pre-configured fallback condition. 【0234】 Option 1: Do not use fallback. 【0235】 Option 2: Fall back to a common random access resource in two steps and resume random access. 【0236】 Option 3: If the signal quality is greater than the third threshold, fall back to a two-step common access resource and resume random access; otherwise, do not fall back. 【0237】 Option 4: Based on the first instruction information transmitted from the base station, if it is determined that a fallback to a common random access resource is possible, random access is resumed by falling back to a 2-step common random access resource; otherwise, no fallback is performed. 【0238】 Option 5: Based on the first instruction information transmitted from the base station, if it is determined that a fallback to a common random access resource is possible and the signal quality is greater than the third threshold, random access is resumed by falling back to the two-step common random access resource; otherwise, no fallback is performed. 【0239】 In the third case, initiating random access with a two-step common random access resource satisfies a pre-configured fallback condition. 【0240】 Option 1: Do not use fallback. 【0241】 Option 2: Fall back to the specified random access resource in step 4 and resume random access. 【0242】 Option 3: If the signal quality is greater than the fourth threshold, fall back to the specified access resource in step 4 and resume random access; otherwise, do not fall back. 【0243】 Option 4: Based on the second instruction information transmitted from the base station, if it is determined that a fallback to a designated random access resource corresponding to the target network slice is possible and the signal quality is greater than the fourth threshold, random access is resumed by falling back to the designated random access resource in step 4; otherwise, no fallback is performed. 【0244】 Option 5: Based on the second instruction information transmitted from the base station, if it is determined that it is possible to fall back to a designated random access resource corresponding to the target network slice, random access is resumed by falling back to the designated random access resource in 4 steps; otherwise, no fallback is performed. 【0245】 The embodiments described above are illustrative only, and all other schemes using the random access scheme provided in this application for a first random access resource and for determining whether or not to fall back to a second random access resource, and for which fallback is performed, should all fall within the scope of this disclosure. 【0246】 This disclosure further provides embodiments of an application function implementation device, corresponding to the embodiments of the application function implementation method described above. 【0247】 Referring to Figure 5, Figure 5 shows a random access device illustrated by an exemplary embodiment, wherein the user equipment (UE) is applied to the device.
