It describes in detail with reference to the accompanying drawing to network slice generation method of the invention:
In technical solution of the present invention, the side RAN needs to support the scheme of end to end network slice:
RAN flanks the end to end network slice (NSSAI) for receiving core net (CN) with postponing, and the side RAN needs while meeting
Operator's Operation and Maintenance requires and the demand of terminal traffic service quality guarantee, so, RAN is collateral hold end to end network slice can
To define corresponding parameter from two angles of the angle of operator's O&M and business/service angle.
As shown in figure 3, core net, which configures NSSAI by SAP (business access point), gives base station (gNB), pass through NSSAI, base
Stand define corresponding parameter from two angles of angle and business/service angle of operator's O&M and generate corresponding configuration and
Control.
Angle from operator's O&M mainly includes equipment management (Platform Management) and network management
The parameter of (Network Management) two aspects.
Equipment management: the dynamic including equipment is shut down and is started, device status monitoring, the laying of equipment, functions of the equipments
Setting, the equipment such as the industrial application of factory and the equipment towards all purpose communication may need to be isolated.In this way in evolution
To after cloud platform, by cloud, can be managed collectively with distribution platform function, for example platform realized by virtualization technology
The without differences ability of equipment, needs equipment Management Function can be realized and manages and controls to all devices.
Network management: division and differentiation including usable range of the network tenant (tenant) on network, network function
Isolation and division, such as industrial application and common communications network function isolation and division, the division for network function of eating dishes without rice or wine,
Such as the setting by emitting antenna, realize the isolation of signal.
It mainly include user management (UEs Management), radio function (Wireless from business/service angle
Function), idle wireless resource frequency domain and time domain management (Radio Resource) and business service quality control (QoS
The parameter of many aspects such as Controlling).
User management: completing the maintenance and storage of user's context for the feature of user, and user's context is established, deleted
When removing, reconfigure and inquiring, accurately result is provided.If user belongs to different virtual operators (Tenant),
It realizes the isolation and safeguard protection of user information, and to meet specific aim requirement of each virtual operator to user information.
Radio function: the demand being sliced according to core net network completes the control of RAN radio function, such as if it is super
The core network service of short time-delay is sliced, then the side RAN needs protocol stack function to be arranged into as far as possible the place close to eating dishes without rice or wine.If
Be time delay it is not very sensitive business, then may be partially installed in distance using being partially installed in close to eating dishes without rice or wine and eat dishes without rice or wine farther out
Equipment on.When network support multiple business, radio function is various, therefore, to assure that radio function control correctness and
Stability.
Idle wireless resource frequency domain and time domain management: for the needs of network management, idle wireless resource is controlled
Management.Such as: the bandwidth of air-interface of 100Mhz is divided into the small bandwidth of several targeted users.Or according to air-interface scheduling
Feature, in real time change interface-free resources feature.Such as different virtual operators, to bandwidth of air-interface realize it is soft every
From.According to customer service form, Real-Time Scheduling distribution is carried out to interface-free resources.
Business service quality control: for core network service slice and network O&M demand, reasonable business service is provided
Quality quantization definition and guarantee.Such as the ultralow time delay business (core for virtual operator's (mark of network O&M input)
The mark of net network slice input), QoS (service quality) control need according to weight of the virtual operator in network O&M and
The feature of ultralow time delay completes the QoS to such business within the scope of RAN enabling capabilities and quantifies definition, and starts guarantee operation.
In technical solution of the present invention, the AS (access layer) of terminal side needs to support the scheme of end to end network slice:
Fig. 4 gives the scheme schematic diagram of the AS support end to end network slice of terminal side.Network side passes through Service
API (application programming interface) issues NSSAI, and NAS (Non-Access Stratum) the configuration NSSAI of terminal is to AS layers, by NSSAI,
AS layers carry out recording the mark, and complete corresponding mapping and control according to RAN signaling.
Eat dishes without rice or wine process and control signaling etc. that AS slice focuses on terminal are soft functionally, do not generate to terminal software and hardware architecture
It influences.
Terminal side mainly configures wireless interface selection (Wireless Interface Selection), idle wireless resource
Frequency domain and multiple sides such as time domain selection (Radio Selection) and business service quality control (QoS Controlling)
The parameter in face.
Wireless interface selection: according to the signaling or instruction of network side, terminal side completes accordingly to eat dishes without rice or wine to select.For example, net
Network side instruction terminal uses the frequency point of industrial application, then terminal side just selects to eat dishes without rice or wine to complete access and data transmit-receive using this.Net
Network side instruction terminal uses the frequency point of all purpose communication, then terminal just eats dishes without rice or wine to complete access and data transmit-receive using this.
Idle wireless resource frequency domain and time domain selection: perhaps indicating according to the signaling of network side or uplink authorization, terminal
Complete corresponding time-frequency domain resources selection in side.
Business service quality control: according to the signaling or instruction to network side, reasonable business service transmitting-receiving is provided.
As shown in figure 5, without the NSSAI that network slice trigger flow is sent in core net (CN), in conjunction with the operation of the side RAN
The strategy and business/service strategy of quotient's O&M, generate the scheme for supporting end-to-end slice, and be allocated to end by wireless signaling
End side.
Firstly, terminal (UE) and network side are by NAS signaling, (signaling of core net and terminal high level is for RAN and AS
Transparent transmission signaling) negotiate to be sliced demand end to end, isolation, quality of service requirement etc. including network slice.
After slice is successfully established end to end, core net notice RAN, which establishes network side, can support the end-to-end slice
Network slice.By sending NSSAI, corresponding quality of service requirement is carried.
Later, after RAN receives NSSAI, following steps are executed:
Step 1: RRC (wireless heterogeneous networks) is after obtaining NSSAI in the signaling that CN is sent, to RRM (radio resource pipe
Reason) send NSSAI request.
After RRM receives the NSSAI, NASSI is parsed, according to the slice quality of service requirement of the core net of NASSI mark, is produced

Scheduling controlling.
4) SDAP (service discovery application configuration file)/PDCP (Packet Data Convergence Protocol)/RLC of network side is (wireless
Link layer control protocol) etc. the protocol stack functions of layers two serving data of user is post-processed.
5) network side selects PHY (physical layer) that is suitable and controlling such as according to network side RRC signaling or network side MAC
Factory is to realize that control needs very high robustness.
Step 2: RRM completes above-mentioned support matching: 1, generating the parameter and scheme of OM (operation and maintenance)；2, nothing is generated
After line resource supports the parameter and scheme of QoS, NSSAI response message is sent to RRC.
Step 3: parameter and arrangements OM of the RRC OM；OM, which is received, to be postponed matching for RRC, and corresponding equipment and net are generated
Network Managed Solution.
Step 4: OM is replied to RRC and is responded: success or failure.If it succeeds, meaning the correspondence of network side slicing
The demand of O&M met, and operated normally.If it fails, needing the reason of carrying failure.
Step 5: after RRC receives the success confirmation message of OM, knowing that network side has successfully supported the network side slicing,
And infrastructure (hardware and network configuration) successful operation.It then generates slice and establishes or reconfigure (existing network side
Slice) signaling to network side L2 (SDAP/PDCP/RLC/MAC) and PHY (physical layer), establish in wireless access network to business/
The radio channel of the strategy of service: carrying, logic channel, scheduling strategy, interface-free resources scheme etc..
Step 6: network side is RAN Slicing Setup or Reconfiguration (slice is established or reconfigured)
Signaling is by eating dishes without rice or wine to be sent to terminal.After the RRC of terminal side receives the signaling of network side RRC, indicate to complete according to signaling empty
The selection and use of mouth.And it replys and is successfully established.
During subsequent signaling and data transmit-receive, after the MAC of terminal side receives the instruction of network side MAC, according to
Indicate the selection and use for completing to eat dishes without rice or wine.
When because terminal movement needs to switch over:
1, it as shown in fig. 6, sending NSSAI Switch (switching) to source base station (Source NB) by core net, sends
NSSAI Request (request) gives purpose base station (Target NB), and new network slice is established in base station side, but to terminal
