Description

TECHNICAL FIELD

[0001] The present disclosure relates to the field of communication technology, and in particular, to a 5G slice access method and device based on base station location, equipment and medium. BACKGROUND

[0002] At present, all application scenarios and customer groups are met by one network in the 4G era, for example, network provides NB-IoT (Narrow Band Internet of Things) capability by opening NB related features on network elements, and network reliability is built by increasing redundant backup at the device level of network elements, and various features are continuously added to meet the demands of the mass market.

[0003] However, the requirements of various businesses in vertical industries in terms of latency, connection number, reliability, security, etc. are very different and unpredictable, for example, virtual reality business needs to use >1600Mbps network super high bandwidth, energy meter reading business needs network to provide massive connections, and automatic driving needs network to guarantee several milliseconds of end-to-end low latency and more than 99.999% high reliability. It is basically impossible to meet all current and future demands through one network.

[0004] Therefore, network slicing technology emerges as the times require. Network slicing technology can let operators split multiple virtual networks from one hardware infrastructure, allocate resources on demand, and flexibly combine capabilities to meet the different needs of various businesses. When new demands are proposed and the current network cannot meet the requirements, operators only need to virtually create a new slice network for this demand, rather than building a new network, to quickly put the business online.

[0005] Specifically, network slicing is to virtually split multiple end-to-end networks from one physical network through slicing technology, each network has different network functions and adapts to different types of service requirements. After the operator purchases physical resources, an eMBB (Enhanced Mobile Broadband) slice network is virtually created from the physical resources for mass Internet access business, and then an mMTC (Massive Machine Type Communication) slice network is virtually created from the physical resources for intelligent metering needs of some manufacturers in the vertical industry, and the two slice networks provide services for different business scenarios respectively.

[0006] In the related art, after completing slice deployment, an operation and maintenance personnel configures slice availability information locally in NSSF (The Network Slice Selection Function), and determines how NSSF completes slice selection service for a UE (user terminal) by setting a data source of NSSF. When the UE initiates an initial registration process, the UE carries SNSSAI information of a request (if not carried, it is a default slice), and sends registration information to an AMF. The AMF determines whether it can provide slice service for the UE according to SNSSAI, TAI (Tracking Area Identity), and other information in the user request, and if so, normally proceeds with the subsequent registration process. If the AMF cannot provide service for the current UE, it sends slice-related information in the UE request to NSSF for AMF reselection.

[0007] In the above process, although it can be determined whether the UE can access the requested slice network by identifying the tracking area where the UE is located, the tracking area has a relatively large range, the boundary is fuzzy, and the tracking area range is determined by an operator, so that factors on a real geographical environment cannot be fully considered, which leads to difficulty for the terminal to accurately access the slice, and it is difficult to meet the demand of the terminal for the accuracy of the slice service range.

[0008] It should be noted that the information disclosed in the above background section is only used to strengthen the understanding of the background of the present disclosure, and therefore can include information that does not constitute prior art known to those of ordinary skill in the art.

[0038] Furthermore, the accompanying drawings are only schematic and are non-limiting detailed descriptions of implementations, as will be described below. Like reference numerals can be used to denote like parts throughout the description. Some of the elements in the drawings can not be to scale and the drawings should not be interpreted on the basis that they are to scale. Determination of appropriate dimensions for the functional elements can be achieved using any appropriate method, including but not limited to experimentation and / or computation. Therefore, the disclosure is not limited by the drawings shown and described herein, which are merely illustrated to clarify the disclosure.

[0039] The solution of terminal accessing dedicated network slice according to the embodiments of the disclosure involves the following important concepts.

[0040] NSSF (The Network Slice Selection Function) network slice selection function, supports the following functions:

[0041] (1) Select the set of network slice instances serving the UE to determine the allowed NSSAI, and determine the mapping of S-NSSAI to the subscription when needed to determine the configured NSSAI, and determine the mapping of S-NSSAI to the subscription when needed.

[0042] (2) Determine the set of AMFs that can be used to query the UE, or determine the list of candidate AMFs based on the configuration (possibly by querying the NRF).

[0043] S-NSSAI (Single Network Slice Selection Assistance Information) identifies a network slice, and its composition includes:

[0044] (1) SST (Slice / Service type), slice / service type, expected network slice behavior in terms of functionality and services.

[0045] (2) SD (Slice Differentiator), a slice differentiator, optional information, a supplementary slice / service type, to differentiate multiple network slices of the same slice / service type.

[0046] Within the 5GC, the NSSF provides services to AMFs and NSSF in different PLMNs (Public Land Mobile Networks) through the Nnssf service-based interface.

[0047] The example embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings.

[0048] Figure 1 is a flowchart of a 5G slice network access method based on base station location in an example embodiment of the present disclosure.

[0049] Reference Figure 1 The 5G slice network access method based on base station location can include:

[0050] Step S102, determine the area identifier of the dedicated slice service.

[0051] Step S104, determine the slice identifier of the dedicated slice service.

[0052] Step S106, store the area identifier and the slice identifier in association.

[0053] Step S108, in response to a registration request for using a slice sent by a terminal device, determine whether the slice service requested by the terminal device is the dedicated slice service according to the area identifier carried in the registration request.

[0054] Step S110, if the slice service is the dedicated slice service, obtain the location of the terminal device and determine whether the location belongs to the area range corresponding to the area identifier.

[0055] Step S112, if it is determined that the location belongs to the area range corresponding to the area identifier, forward the registration request to the AMF.

[0056] Step S114, if it is determined that the location does not belong to the area range corresponding to the area identifier, feed back a response of rejecting the registration request to the terminal device.

[0057] Figure 2 is a flowchart of a 5G slice network access method based on base station location in an example embodiment of the present disclosure.

[0058] Reference Figure 2 The 5G slice network access method based on base station location can include:

[0059] Step S202: Determine the region identifier for the dedicated slice service.

[0060] Step S204: Determine the slice identifier of the exclusive slice service.

[0061] Step S206: Associate the region identifier and the slice identifier and send them to the AMF.

[0062] Step S208: In response to the registration request for using a slice sent by the terminal device, the registration request is sent to the AMF so that the AMF can determine whether the slice service requested by the terminal device is the dedicated slice service based on the area identifier carried in the registration request.

[0063] Step S210: If the slicing service is the dedicated slicing service, then obtain the location of the terminal device and determine whether the location belongs to the area range corresponding to the area identifier.

[0064] Step S212: If it is determined that the location belongs to the area range corresponding to the area identifier, then the registration request is forwarded to the AMF.

[0065] Step S214: If it is determined that the location does not belong to the area range corresponding to the area identifier, then a response rejecting the registration request is sent to the terminal device.

[0066] This embodiment of the disclosure quantifies the relative position between the base station and the dedicated slice area, and determines whether the terminal device belongs to the requested dedicated slice area by the relative positional relationship between the base station and the terminal device. This improves the reliability of the terminal accessing the dedicated slice service and meets the terminal's requirement for the accuracy of the dedicated slice service.

[0067] The following section provides a detailed explanation of each step in the 5G slicing network access method based on base station location.

[0068] In one exemplary embodiment of this disclosure, such as Figure 3 As shown, before responding to the registration request for using slices sent by the terminal device, it also includes:

[0069] Step S302: Determine the fan-shaped area formed by the tangent line between the positioning point of the base station and the area of ​​the dedicated slice service.

[0070] Step S304: Using the positioning point as the vertex, divide the sector area into at least one sector sub-region.

[0071] Step S306: Record the intersection area of ​​any of the fan-shaped sub-regions and the region of the dedicated slice service as a region range.

[0072] Step S308: Determine the angle, maximum distance, and minimum distance between any of the said area ranges and the positioning point.

[0073] In the above embodiments, the dedicated slice service area is a continuous closed shape. The continuous closed shape is within a fan-shaped area, and both straight edges of the fan-shaped area are tangent to the edges of the continuous closed shape. Only if the terminal device belongs to the fan-shaped area can it belong to the dedicated slice service area.

[0074] Furthermore, the sector region is divided into more sub-sectors. The more sub-sectors are divided into, the smaller the maximum value of the apex angle of the sub-sectors will be. In this case, the range of the quantified sub-sectors obtained by the included angle, maximum distance, and minimum distance will be more accurate.

[0075] In one exemplary embodiment of this disclosure, such as Figure 4 As shown, if the slicing service is the dedicated slicing service, then obtaining the location of the terminal device and determining whether the location belongs to the area range corresponding to the area identifier includes:

[0076] Step S402: If the slicing service is the dedicated slicing service, then obtain the location of the terminal device.

[0077] Step S404: Determine the angle information and distance between the position of the terminal device and the positioning point.

[0078] Step S406: Determine the target angle that is closest to the angle information.

[0079] Step S408: Determine the maximum and minimum distances corresponding to a region range corresponding to the included angle of the target.

[0080] Step S410: Determine whether the distance is greater than or equal to the minimum distance and less than or equal to the maximum distance.

[0081] In the above embodiments, the relative position between the terminal device and the base station includes distance and angle information. The reference coordinate system of the angle information is the same as the reference coordinate system of the angle between the three sectors. If it is determined through the angle information that the terminal device does not belong to the three sectors, the base station can send an indication of rejection request to the terminal device.

[0082] Furthermore, after quantifying the sector area into numerous sub-sectors, distance and angle information can be used to determine whether a terminal device belongs to any sub-sector.

[0083] In one exemplary embodiment of this disclosure, such as Figure 5 As shown, if it is determined that the location belongs to the area range corresponding to the area identifier, then forwarding the registration request to the AMF includes:

[0084] Step S502: If it is determined that the distance is greater than or equal to the minimum distance and less than or equal to the maximum distance, then the location is determined to belong to the area range, and the registration request is forwarded to the AMF.

[0085] In one exemplary embodiment of this disclosure, such as Figure 6 As shown, if it is determined that the location does not belong to the area range corresponding to the area identifier, the response sent to the terminal device to reject the registration request includes:

[0086] Step S602: If it is determined that the distance is less than the minimum distance or greater than the maximum distance, then it is determined that the location does not belong to the area range, and a response rejecting the registration request is sent to the terminal device.

[0087] In one exemplary embodiment of this disclosure, such as Figure 7 As shown, obtaining the location of the terminal device includes:

[0088] Step S702: Use the E-CID algorithm to determine the distance between the terminal device and the positioning point.

[0089] Step S704: Use the AOA algorithm to determine the relative angle information between the terminal device and the positioning point.

[0090] Step S706: Determine the distance and angle information as the position of the terminal device.

[0091] In the above embodiments, E-CID (Enhanced Cell-ID) refers to enhanced positioning technology based on Cell ID, including Cell ID+RTT, Cell+RTT+AoA, etc. Cell ID+RTT adds RTT (Round Trip Time) measurement to Cell ID, specifically using TA (Time Advance) to determine the time it takes for the signal to travel from the phone to the base station, or from the base station to the phone, and then multiplying this by the speed of light (the speed of wireless signal propagation) to estimate the distance between the phone and the base station. With Cell ID+RTT positioning, distance estimation can be performed on three nearby base stations to improve positioning accuracy. In Cell ID+RTT+AoA, AoA (Angle-of-Arrival) uses the angle of incidence of the phone signal to the base station to further determine the phone's location in that area.

[0092] like Figure 8 As shown, the 5G slicing network access scheme based on base station location includes UE 802, (R)an 804 (base station), and AMF 806. Slicing access is implemented according to the following steps:

[0093] 1. UE 802 sends a registration request to (R)an 804 (base station), carrying SNSSAI.

[0094] 2. (R)an 804 determines whether this SNSSAI is a region-specific slice based on the exclusive area identifier. If so, it triggers location information acquisition to determine whether the UE is in the relevant area. If the slice is an exclusive slice and the UE is not in the area, the request is directly rejected.

[0095] 3. When a user is in a dedicated slice area or a public slice requested by the user, (R)an 804 sends a normal user registration request to AMF 806.

[0096] In the slice configuration process, a dedicated region identifier for the slice is added, which indicates the region ID of the dedicated slice service.

[0097] Specifically, it is necessary to configure the SNSSAI and exclusive area ID of the dedicated slice on the base station, such as...<SNSSAI,AREAID> When a UE sends a registration information request to use a slice, the eNB (base station) determines whether the SNSSAI in the signaling is a region-specific slice based on the exclusive area identifier. If it is a region-specific slice, location information acquisition is triggered to determine whether the UE is within the relevant area. If the slice is a region-specific slice and the user is not within the area, the request is directly rejected. If the user is within the area, the process is the same as for public network slices, and the user registration information is sent to the AMF normally.

[0098] Based on the existing network planning information, query the base station information serving this geographical area, including enbid (base station identifier) ​​and coordinates, as reference points for determining the slice service area. If there is more than one base station covering any park or community, all of them must be considered.

[0099] like Figure 9 As shown, any base station 902 is selected as a reference point. The angle of the dedicated slice service range 904 relative to base station 902 is calculated, and the nearest distance a and the farthest distance b are calculated. The data storage method is as follows:<enbid,areaid,angle,minlength,maxlength> These correspond to the base station ID, specific area ID, relative angle, minimum distance, and maximum distance, respectively.

[0100] Furthermore, multiple lines are drawn from base station 902 (such as...) Figure 9The first tangent 9061, the second tangent 9062 and the nth tangent 906n shown divide the exclusive slice service range 904 into n-1 sub-sectors and corresponding n-1 angle information. The larger n is, the more angle data is selected, the more accurately a slice area can be identified, and the higher the accuracy of determining whether the user is in the area.

[0101] like Figure 10 As shown, the 5G slicing network access method based on base station location may include:

[0102] Step S1002: Configure a dedicated slice area identifier.

[0103] In one embodiment of this disclosure, a dedicated area identifier for the slice is added, which indicates the area ID of the dedicated slice service. The SNSSAI and dedicated area ID of the dedicated slice can be configured on the base station, such as...<SNSSAI,AREAID> .

[0104] Step S1004: Obtain base station information serving any area.

[0105] In one embodiment of this disclosure, based on existing network planning information, basic information of base stations serving this geographical area is queried, including enbid, coordinates, etc., as reference points for determining the slice service range. If there is more than one base station covering any park or community, all of them must be considered.

[0106] Step S1006: Quantify the relative positional relationship between the region and the base station.

[0107] In one embodiment of this disclosure, the method for quantifying the relative positional relationship between the region and the base station is as follows: selecting a base station as a reference point, calculating the angle of a slice's service area relative to the base station, calculating the nearest and farthest distances, and storing the data in the following manner:<enbid,areaid,angle,minlength,maxlength> These correspond to the base station ID, specific area ID, relative angle, minimum distance, and maximum distance, respectively. For example, if the base station ID is 100, the specific area identifier is dianxin01, the angle information is 30°, and the nearest and farthest distances are 10 meters and 20 meters, then the data format is <100, dianxin01, 30, 10, 20>.

[0108] In one embodiment of this disclosure, the quantized region is identified relative to the base station using polar coordinates; in some other embodiments, planar two-dimensional coordinates may also be used.

[0109] Step S1008: The UE requests a dedicated slice to determine the UE's location.

[0110] In one embodiment of this disclosure, when a user accesses a slice containing a dedicated area ID identifier, the base station needs to use the E-CID algorithm to calculate the UE's location, obtaining the user's relative angle and distance from the base station.

[0111] Step S1010: Determine whether the UE is within the area of ​​the dedicated slice. If yes, proceed to step S1012; otherwise, proceed to step S1014.

[0112] Step S1012: Forward the request to AMF for the normal registration process.

[0113] Step S1014: Reject the UE request.

[0114] Corresponding to the above method embodiments, this disclosure also provides a 5G slicing network access device based on base station location, which can be used to execute the above method embodiments.

[0121] The judgment module 1106 is configured to, if the slicing service is the dedicated slicing service, obtain the location of the terminal device and determine whether the location belongs to the area range corresponding to the area identifier. If it is determined that the location belongs to the area range corresponding to the area identifier, the registration request is forwarded to the AMF. If it is determined that the location does not belong to the area range corresponding to the area identifier, a response rejecting the registration request is sent to the terminal device.

[0127] The sending module 1204 is configured to send a registration request for using a slice to the AMF in response to a registration request sent by a terminal device. The AMF then determines, based on the region identifier carried in the registration request, whether the slice service requested by the terminal device is the dedicated slice service. If the slice service is the dedicated slice service, the location of the terminal device is obtained, and it is determined whether the location belongs to the region range corresponding to the region identifier. If the location belongs to the region range corresponding to the region identifier, the registration request is forwarded to the AMF. If the location does not belong to the region range corresponding to the region identifier, a response rejecting the registration request is sent to the terminal device.
