Description

Network slice configuration method, device and storage medium

Technical Field

The application relates to the technical field of mobile communication, in particular to a network slice configuration method, a device and a storage medium.

Background

In a wireless communication system, a network slice cuts one physical network into multiple virtual end-to-end networks. The network slice can be used by an operator to provide mutually isolated and functionally customizable network services for different vertical industries, different customers and different services based on business service agreements (Service level Agreement, SLA) signed by the operator with customers. A network slice is a logical network that provides specific network capabilities and characteristics, and is carried by network slice instances, which are deployed network slices that include network function instances and required resources, such as computing, storage, and networking, to enable the design, deployment, and operation of customized network slices.

The network slice meets the requirements of different service differentiation services, and provides a corresponding basis for the realization of various application scenes. In a fifth generation communication technology (The 5th Generation Mobile Communication Technology,5G) system, network resources are flexibly allocated by end-to-end network slices, and networking is performed according to needs; based on the 5G network, a plurality of logic subnets which have different characteristics and are isolated from each other are virtually formed by combining the wireless network, the transmission network and the core network sub-slices, and are uniformly managed through an end-to-end slice management system. In the process of network slice configuration, the granularity of slices needs to be selected based on the actual requirements of the traffic scenario to reasonably slice the network resources. In the related art, the configuration mode of the network slice is usually a manual configuration mode, and the configuration of the network slice is completed manually according to the planning of the core network. However, the manual configuration method is easy to cause missing configuration of the slice service, and further causes interruption of the user service.

The following embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments. Embodiments of the present application will be described below with reference to the accompanying drawings.

Embodiments of the present application provide a possible implementation manner, as shown in fig. 1, and provide a flowchart of a network slice configuration method, where the method may be performed by a network device, and optionally, the network device may be an access network device, for example, a base station (gNB) or an operation maintenance center (Operation and Maintenance Center, OMC).

As shown in fig. 1, the method may include the steps of:

step 101, detecting a newly added first network slice, and acquiring source information of the first network slice.

And acquiring source information of the first network slice when detecting that the network equipment side is newly added with the network slice, namely the first network slice. Specifically, in a 5G network, the network slices include a radio sub-slice of a radio domain, a transport sub-slice of a transport domain, and a core network sub-slice of a core network domain; wireless sub-slices such as Centralized Unit (CU) network elements, distributed Unit (DU) network elements, and wireless sub-slices formed by base stations; a transmission sub-slice, e.g., a transmission sub-slice formed by a transmission device of a transmission domain; the transport sub-slices are core network sub-slices formed by virtual network functions such as access to the core network domain, mobility management functions (Access and Mobility Management Function), session management functions (Session Management Function, SMF), user plane functions (User Plane Function), network slice selection functions (Network Slice Selection Function, NSSF), network element data warehouse functions (NF Repository Function, NRF), network capability open functions (Network Exposure Function, NEF), short message service functions (Short Message Service Function, SMSF), and the like. The network sub-slice and the internal virtual network function together form an end-to-end network slice under the management of the slice management system, and network communication service is provided.

The source information indicates a source of the first network slice; alternatively, the source may be a User Equipment (UE) random access procedure, a UE initial registration procedure, or a gNB start-up or cutover NG establishment procedure. The NG interface is a link interface for communication between the radio access network and the core network.

Step 102, obtaining slice parameter information of the first network slice according to the source information.

Slice parameter information such as network slice selection assistance information (Network Slice Selection Assistance Information, NSSAI), timing advance commands (Timing Advance Command, TAC), public land mobile network (Public Land Mobile Network, PLMN), virtual local area network (Virtual Local Area Network, VLAN), quality of service (Quality of Service, qoS), etc.

For different source information, the acquisition paths of slice parameter information are different; for example, for a network slice carried by a UE random access procedure, the acquired slice parameter information may be acquired from a random access preamble sequence; the slice carried in by the UE initial registration procedure may be obtained from a context setup request message sent by the UE.

And step 103, configuring the first network slice in a network device according to the slice parameter information.

After the slice parameter information is obtained, the first network slice is configured in the network equipment according to the slice parameter information, and the first network slice is written into a global slice information table or a slice information table of a base station, so that automatic configuration of the network slice is realized. The network equipment side can set a periodic or real-time initiation slice configuration task to detect whether a network slice is newly added, if so, the slice source is acquired, and slice parameter information is acquired according to the slice source, so that the situation of slice configuration missing can be avoided and the slice configuration missing rate can be reduced through automatic configuration of the network equipment.

In the embodiment of the application, a newly added first network slice is detected, and source information of the first network slice is acquired; acquiring slice parameter information of the first network slice according to the source information; according to the slice parameter information, configuring the first network slice in the network equipment, and automatically configuring the slice through the network equipment, so that the reliability is higher, and the situation that the service interruption of a user is caused by the missing configuration of the slice is avoided; compared with manual configuration, the configuration time can be shortened, and the labor cost is saved. The embodiment of the application solves the problem that the manual configuration of the network slice is easy to cause the configuration missing of the slice service in the prior art.

In an optional embodiment, the acquiring slice parameter information of the first network slice according to the source information includes at least one of a first case to a third case:

case one: and under the condition that the source information comprises network slice selection auxiliary information NSSAI carried in a random access process of User Equipment (UE), acquiring a random access leading code sequence sent by the UE, and determining slice parameter information of the first network slice according to the random access leading code sequence.

Wherein, in case that the source information of the first network slice includes a network nsai carried by the random access procedure, the network slice comes from the random access procedure of the UE; in the random access process, the UE transmits a predetermined sequence as a random access preamble on a Physical Random Access Channel (PRACH), the network equipment receives the random access preamble sequence, and slice parameter information of the first network slice is determined according to the random access preamble sequence.

And a second case: and acquiring slice parameter information carried by the NG establishment response message in the source information comprising the network equipment start-up process and/or the cut-over NG interface establishment process.

Wherein the network device outbound procedure is, for example, an outbound procedure of a base station; and if the first network slice is from the network equipment start-up process and/or the cut-over NG interface establishment process, acquiring slice parameter information carried in the NG establishment response message (NG setup response).

Specifically, a network device start-up procedure, such as a base station start-up procedure, includes, for example: collecting relevant configuration data of a base station to be deployed in a network planning stage, and deploying the relevant configuration data into hardware equipment of the base station; after deployment is completed, the base station is powered on to provide service.

The NG interface is a link interface for communication between the wireless access network and the core network; the cutting NG interface process is the network cutting between the wireless access network and the core network; network cutoffs typically respond to adjustments in network architecture, adding or replacing network devices, changing lines, changing device configurations, or other changing needs for the network. For example, the line or equipment between networks is adjusted to modify, upgrade, migrate, change, etc. the network operation is performed, and at the same time, these network operation behaviors occur on the network that is carrying traffic, and network cutover cannot affect the traffic.

And a third case: and acquiring slice parameter information carried by the initial message of the UE under the condition that the source information comprises NSSAI carried by the initial registration process of the UE.

If the first network slice is from the initial registration process of the UE, slice parameter information carried in an initial message is acquired; the initial message is a context setup request message.

In an optional embodiment, in the first case, the determining slice parameter information of the first network slice according to the random access preamble sequence includes:

The network equipment determines random access time information of the UE according to the random access preamble sequence; wherein, the random access time information is the time of accessing to the physical random access channel when the UE transmits the random access lead code. Then, according to the first corresponding relation, slice identification information corresponding to the target random access time information is determined; the first corresponding relation comprises a corresponding relation between the slice identifier and the time of accessing the physical random access channel; finally, slice parameter information of the first network slice is determined according to the slice identification; optionally, the network device records the identifier of the network slice which is signed and ordered by the user SIM card corresponding to the UE and the slice parameter, and obtains the slice parameter information according to the slice identifier after determining the slice identifier.

In an optional embodiment, in the third case, the acquiring slice parameter information carried by the initial message of the UE includes:

If the first network slice is from the initial registration process of the UE, a context establishment request message and/or slice parameter information in a context message that the UE completes the initial registration process are acquired.

In an alternative embodiment, the configuring the first network slice in the network device includes:

or (b)

The NSSAI information supported by the network equipment is required to be matched with the permission NSSAI (Allowed NSSAI) of the UE, and the first network slice is configured in the network equipment under the condition that the Allowed NSSAI of the UE is the NSSAI supported by the network equipment; if the Allowed nsai of the UE is an nsai that is not supported by the network device, determining whether to add the slice information according to a preset nsai list; if the preset NSSAI list comprises the first network slice, the slice information is allowed to be added, otherwise, the slice information is not added. In this way, the first network slice is avoided from being a network slice not supported by the base station, which affects the establishment of a subsequent user protocol data unit (Protocol Data Unit, PDU) session.

In an alternative embodiment, the network device includes a slice storage module; the slice storage module is a database for storing slices of the network device

the first slice information table is a global slice information table supported by the core network and records slice information supported by the core network; the second slice information table is slice information supported by the network equipment; the third slice information table carries slice information supported by the overlay cell of the network device.

The configuring the first network slice in the network device includes one of the following modes one to three:

in a first aspect, when the first slice information table does not include the first network slice, the first network slice is added to the first slice information table;

in a second mode, when the first slice information table includes the first network slice and the second slice information table does not include the first network slice, the first network slice is added to the second slice information table;

In a third aspect, when the first network slice is included in the second slice information table and the first network slice is not included in the third slice information table, the first network slice is added to the third slice information table.

The process of configuring the network slice at the network equipment side further comprises a storing and deduplication process; during the storage and deduplication process, configuration granularity is gradually reduced: firstly, judging whether a first network slice is stored in a global slice information table (a first slice information table); if not, adding the first network slice to the first slice information table;

if yes, the granularity is reduced, and whether the second slice information table exists in the network equipment is further judged: if not, adding the first network slice to the second slice information table; if so, further judging whether a third slice information table of the coverage cell of the network equipment exists:

if not, the first network slice is added to the third slice information table.

As an example, referring to fig. 2, fig. 2 shows an application scenario of the network slice configuration method provided by the embodiment of the present application; wherein the network device may comprise: a base station 21 and an OMC22; the base station 21 comprises a base station master control unit 23, a transmission unit 24, and a database.

The database is used for storing slice information acquired from the UE and slice information acquired by the AMF, can read and transmit data in real time, establishes a slice information table and transmits real-time data to the base station and the OMC.

The base station main control unit 23 and the transmission unit 24 are used for receiving the data sent by the database, and completing the initial configuration of the relevant parameters of the slice.

The OMC reads and processes the measurement data transmitted by the base station, provides an interface for setting a measurement task and executes a real-time measurement task.

Specifically, the base station 21 or OMC22 triggers step 201, and the slice configuration trigger starts to issue a configuration task; the information is transmitted to the base station master control unit 23 via the transmission unit 24, and is transmitted to the database by the base station master control unit 23.

The base station 21 or OMC22 executes step 202 to compare whether the slice is a newly added slice or not based on the slice information recorded in the database; step 203, determining the source of the newly added slice (first network slice); step 204, determining slice parameter information to be added;

in step 205, the granularity determination is gradually reduced a plurality of times, and slice parameter information is determined.

In step 206, the configuration result (i.e. whether the configuration was successful or not, and the slice information table added thereto) is transmitted back to the master control unit 23 of the base station and the OMC22 by the transmission unit 24.

If the configuration is successful, the base station 21 executes step 208, the configuration is completed, and the result is output;

if the configuration fails, the base station 21 performs step 207, and initiates a failed reconfiguration procedure.

Further, as shown in fig. 3, the above-mentioned steps 202 to 205 specifically include the following steps:

after triggering the measurement configuration task, firstly, judging the source information of the newly added slice, taking 3 sources as an example:

source 1:

step 3011, carrying NSSAI for the random access process of the UE;

step 3012, the base station receives a random access preamble sent by the UE;

step 3013, according to the first correspondence, determining whether the preamble corresponds to the first network slice: if so, execute step 304; otherwise, step 3014 is executed to trigger a normal rejection procedure to reject configuration of the first network slice.

Source 2:

step 3021, establishing a procedure for newly opening or cutting NG;

in step 3022, the base station receives NG setup response the AMF reply, obtains slice information, and executes step 304.

Source 3:

step 3031, carrying NSSAI for initial registration of UE;

in step 3032, the base station receives the INITIAL message of the UE, acquires slice information, and executes step 304. The INITIAL message is an INITIAL message, such as a context setup request message.

Step 304, storing a database, storing slices and removing duplication;

step 305, determining whether the first network slice exists in the global slice information table: if not, executing step 306, and adding the first network slice to the global slice information table; and proceeds to step 307 to avoid missing slices.

If yes, go to step 307, determine whether the first network slice exists in the gNB supported network slice table (second slice information table): if not, adding the slice information into a second slice information table;

if yes, go to step 308, determine whether the first network slice exists in the cell slice configuration parameter table (third slice information table): if not, adding the slice information to the third slice information table.

Step 309, adding the rules in the steps 305 to 308 to a preset matching slice algorithm parameter configuration table.

Step 310, report the configuration result to OMC.
