AI Technical Summary
In existing technologies, when users move across AMFs, wireless access networks need to perform slice determination through the Default AMF, which leads to an increase in end-to-end latency.
By accessing the network device and determining the target AMF set based on the GUAMI information in the terminal registration request, the registration request is sent directly to the set, thus avoiding the redirection process of the Default AMF.
It reduces end-to-end signaling latency and improves the efficiency and accuracy of network access selection.

Abstract
Description
Technical Field
[0001] This application relates to the field of communication technology, and in particular to an information processing method, apparatus, device and readable storage medium. Background Technology
[0002] Currently, after receiving a user registration request, the radio access network selects a network. Typically, the radio access network selects the AMF based on the user's GUAMI (Globally Unique AMF Identifier) or the slice information carried by the AS (Access Stratum) layer.
[0003] In the above process, network selection based on the slice information carried by the user requires the AS layer to carry plaintext slices. This can lead to network slice information being eavesdropped on over the air interface, and for security reasons, its application is not recommended. Therefore, if slice-based network selection is currently unavailable, when a user moves across AMFs, the radio access network can only send the user's registration request to the Default AMF. The Default AMF interacts with multiple control plane network elements and performs slice determination before redirecting to the corresponding access network AMF. It can be seen that the above process increases end-to-end latency. Summary of the Invention

[0063] In the embodiments of this application, the term "and / or" describes the relationship between associated objects, indicating that three relationships can exist. For example, A and / or B can represent three cases: A alone, A and B simultaneously, and B alone. The character " / " generally indicates that the preceding and following associated objects have an "or" relationship.
[0064] In the embodiments of this application, the term "multiple" refers to two or more, and other quantifiers are similar.
[0065] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.
[0066] The concept of slicing is introduced in 5G to achieve end-to-end isolation of functions and resources, thereby meeting different network requirements. A slice represents a collection of end-to-end network capabilities and resources. The AMF (Access Provider Function) is the node responsible for user access and mobility management; a single terminal can only access one AMF at a time. If a terminal uses multiple slices simultaneously, the AMF should support as many slices as possible.
[0067] Wireless resources are generally shared across different networks. When a user accesses a shared access network, combined with... Figure 1 As shown, in the prior art, upon receiving a registration request from a terminal, the access network side selects an access network. The access network side can make this selection based on the carried GUAMI or the slice information carried by the AS layer. When the carried GUAMI is valid, the access network side can select an available core network (Target AMF) based on the user-carried GUAMI. When the carried GUAMI is invalid but the carried slice information is valid, the access network side can select an available core network (Target AMF) based on the user-carried slice information. When both are invalid, the access network side sends the registration request to the Default AMF. The Default AMF interacts with each control plane network element (SMF (Session Management Function), UPF (User Plane Function)) to determine the subscribed slice, establishes a list of slices allowed for the terminal, and then redirects the user registration request to an available core network. When the terminal moves out of its original AMF area, the above process is repeated.
[0068] For example, during initial terminal registration, the access network side (e.g., base station 1) can send the registration request to the Default AMF. For example, when a terminal re-registers or moves within a pool, the access network side (e.g., base station 2) can select an available core network (Target AMF) based on the user's GUAMI. For example, when a terminal moves across pools in idle mode, or moves from 4G to 5G in idle mode, if the GUAMI information is invalid, the access network side (e.g., base station 3) selects an available core network based on the slice information carried by the user's AS layer; if both the slice information and the GUAMI information are invalid, the access network side sends the registration request to the Default AMF. The Default AMF interacts with each control plane network element, performs a subscription slice determination, determines the list of slices allowed for the terminal, and then redirects the user registration request to an available core network. When the terminal moves out of its original AMF area, the above determination process is repeated.
[0069] Using existing technologies would trigger an AMF redirection process every time a terminal moves across the AMF, which would increase the interaction process between multiple network elements and thus increase end-to-end signaling latency.
[0070] To address the aforementioned problems, embodiments of this application provide an information processing method to reduce end-to-end signaling latency. The following describes the solutions of this application in detail with reference to different embodiments.
[0071] See Figure 2 , Figure 2 This is a flowchart of an information processing method provided in an embodiment of this application, applied to access network equipment, such as a base station. Figure 2 As shown, it includes the following steps:
[0072] Step 201: Receive a registration request from the terminal. The registration request includes a GUAMI, which includes information about the first access network.
[0073] As shown in Table 1, GUAMI includes MCC (Mobile country code), MNC (Mobile Network Code), AMF Region ID, AMF Set ID, and AMF Pointer. The AMF Set ID is 10 bits.
[0074] Table 1
[0075]
[0076] In this embodiment, the first access network is one or more networks that have been accessed by one or more slices, and the one or more slices are the slices corresponding to the service requested by the terminal. The first access network being a network that one or more slices have accessed can be understood as an access network that the terminal has historically accessed. For example, an access network that one or more slices successfully accessed before executing this embodiment can be used as the first access network. The service requested by the terminal may include voice, video, etc.
[0077] The information of the first access network is carried in the AMF Set ID of GUAMI.
[0078] In this embodiment, one or more bits from the AMF group identifier of GUAMI are used as the access network bit, which is used to identify the access network. When the access networks are the same, the value of the access network bit is the same; when the access networks are different, the value of the access network bit is different. In this way, different access networks can be accurately distinguished, thereby facilitating the subsequent selection of the access network.
[0079] Specifically, one or more bits of the AMF Set ID can be used to identify the access network, representing the information of the first access network. This information may include, for example, the name, ID, and index of the first access network. In practical applications, the terminal can obtain the information of the first access network from the network equipment in the core network.
[0080] Step 202: Determine the target AMF set based on the information of the first access network, wherein the target AMF set corresponds to the first access network.
[0081] Optionally, in this embodiment, candidate AMFs can be divided into one or more AMF sets, with different AMF sets corresponding to different access networks. Accordingly, in this step, when an access network cannot be accurately selected, a target AMF set is determined from one or more AMF sets based on the information of the first access network. The inability to accurately select an access network may include the inability to select an access network based on GUAMI in the manner described in the prior art, or the inability to select an access network based on slice information. By dividing candidate AMFs into one or more AMF sets, the subsequent selection of access networks can be facilitated, thereby improving the efficiency of access network selection and further reducing end-to-end latency.
[0082] Candidate AMFs can include all or some of the AMFs in the network. During partitioning, candidate AMFs can be divided into one or more AMF sets based on the access networks corresponding to different AMFs, with different AMF sets corresponding to different access networks. Furthermore, identifiers can be set for different AMF sets to identify the access networks corresponding to each AMF set.
[0083] Specifically, in this embodiment, the AMF (Access Capability Frame) is divided into multiple sets (or access capability clusters) according to the terminal's slice's requirement for accessing different networks. A specific AMF set or cluster represents the same access network. When a terminal moves within a certain range, it typically accesses an AMF set with the same access capability. Simultaneously, certain bits in the AMF SetID can be defined as the "access network" bit to represent different access networks. For example, an eMBB (Enhanced Mobile Broadband) slice set corresponds to one set of access networks, where "access network" = 1 in the AMF Set ID; a URLLC (Ultra-reliable and Low Latency Communications) slice set corresponds to one set of access networks, where "access network" = 2 in the AMF Set ID.
[0084] Typically, multiple Access Providers (AMFs) can serve different regions, where the AMF Region ID represents the region where the AMF is located. In this embodiment, AMFs in different regions can also be grouped into an AMF set corresponding to the same access network. Therefore, in this embodiment, if they correspond to the same access network, the "Access Network" bit in the AMF Set ID has the same value; if the access networks are different, the "Access Network" bit has a different value.
[0085] In multi-slice user mobility scenarios involving AMF changes, when a terminal moves, the access network device receives the terminal's registration request and selects an available AMF based on the GUAMI carried by the terminal. If the GUAMI information carried by the terminal is invalid, the access network device selects the core network based on the slice information carried by the user's AS layer. If the terminal does not carry valid slice information and GUAMI information, the access network device can determine the target AMF set based on the information of the first access network carried in the AMF group identifier of the GUAMI.
[0086] Specifically, the access network device can determine the target AMF set based on the information of the first access network and the correspondence between the AMF set and the access network. The correspondence between the AMF set and the access network can be, for example, the correspondence between access network information (such as an identifier) and the AMF set.
[0087] For example, the information of the first access network includes the name of the first access network; the correspondence between the AMF set and the access network includes the correspondence between the AMF set and the name of the access network. Therefore, in this step, based on the name of the first access network, the correspondence between the AMF set and the name of the access network is searched. Based on the search result, a second access network with the same name as the first access network is determined, and the AMF set corresponding to the second access network is taken as the target AMF set.
[0088] For example, the information of the first access network includes the ID of the first access network; the correspondence between the AMF set and the access network includes the correspondence between the AMF set and the index of the access network. Therefore, in this step, based on the ID of the first access network, the correspondence between the AMF set and the index of the access network is found, and based on the search result, a third access network with the same ID as the first access network is determined, and the AMF set corresponding to the third access network is taken as the target AMF set.
[0089] The above methods can improve the flexibility of determining the target AMF set. Of course, the embodiments of this application are not limited to determining the target AMF set through the above methods.
[0090] If the target AMF set cannot be determined, the default AMF can be selected to handle the terminal's registration request.
[0091] Step 203: Send the registration request to the target AMF set.
[0092] In this embodiment, if the target set of AMFs includes one AMF, a registration request can be sent directly to that AMF. If the target set of AMFs includes multiple AMFs, a target AMF can be selected from them according to a preset strategy, and a registration request can be sent to that target AMF. For example, any AMF can be selected as the target AMF, or the target AMF can be selected based on the load size, for example, selecting the AMF with a smaller load as the target AMF.
[0093] As can be seen from the above description, in this embodiment, the target AMF set can be determined based on the information of the first access network in the GUAMI carried in the terminal registration request. The access network corresponding to the target AMF set is the same as the first access network, thus a registration request can be sent to the target AMF set. Therefore, it can be seen that, using the solution of this embodiment, since one or more slices have accessed the first access network, and the GUAMI carries information about the first access network, the target AMF set can be determined based on the information of the first access network, thereby reducing the slice redirection process and lowering end-to-end latency.
