Specific embodiment
The characteristics of in order to more fully hereinafter understand the embodiment of the present invention and technology contents, with reference to the accompanying drawing to this hair
The realization of bright embodiment is described in detail, appended attached drawing purposes of discussion only for reference, is not used to limit the embodiment of the present invention.
The concept of network slice (slice) is proposed in the related technology in 5G system at present；It is substantially exactly will fortune
The physical network of battalion quotient is logically divided into multiple virtual networks, each virtual network is carried out according to different demands for services
It divides, for example can be divided according to service requirement informations such as time delay, bandwidth, priority, safety and reliabilities, so as to
It is enough flexibly to cope with different network application scenes.It is therefore, mutually isolated between heterogeneous networks slice (namely virtual network),
So that the error or fault of network slice does not interfere with the normal communication of other network slices.
Based on the above-mentioned explanation for network slice, it is known that network slice type may include access network slice
(Access Network slice), core network are sliced (Core Network slice) and data network and service slice
(Data Network and Service slice).So carried out access control (AC) for network slice, it is involved
Network side equipment includes the wireless access network equipment of 5G system, such as gNB；It can also include the equipment of the core network of 5G system, than
Such as core access and mobile management (AMF, Core Access and Mobility Management Function).Cause
This, the technical solution of the embodiment of the present invention can be applied to network architecture scene shown in FIG. 1 atypically, in the scene
In, after terminal can be linked into wireless access network (RAN), 5G core net is linked by N2 interface；N1 can also directly be passed through
Interface is attached with 5G core net.It should be noted that N1 is the NAS signaling interface of UE and AMF, N2 is between gNB and AMF
Interface.In addition, wireless access network (RAN) equipment may include gNB in scene shown in Fig. 1；5G equipment of the core network can be with
Including AMF；User equipment (UE, User Equipment) may include cellular phone, smart phone, Session initiation Protocol
(SIP) phone, laptop computer, personal digital assistant (PDA), satelline radio, global positioning system, multimedia equipment,
Video equipment, digital audio-frequency player (for example, MP3 player), camera, game console, tablet computer or it is any its
It has the equipment of similar functions.At the same time, user equipment can also be generally referred to by those skilled in the art as terminal, movement station,
It is subscriber station, mobile unit, subscriber unit, radio-cell, remote unit, mobile device, wireless device, wireless telecom equipment, remote
Journey equipment, mobile subscriber station, access terminal, mobile terminal, wireless terminal, remote terminal, hand-held set, user agent, mobile visitor
Family end, client or some other term appropriate.
Based on the network architecture shown in FIG. 1, it is sliced mechanism in presently relevant network, mainly for network side and UE
Non-Access Stratum (NAS, Non-Access Stratum), but the access layer of UE (AS, Access Stratum) cuts network
It is almost transparent for piece, for example, including Master Information Block (MIB, Master Information Block), remaining minimum system
NR system including system information (RMSI, Remaining Minimum System Information) and other systems information
Information is without carrying network slice information.Based on this, the UE of idle IDLE state can not know net by reading system information
The network that network side provides is sliced service.If UE expectation obtains network and is sliced relevant service, it is necessary to go forward side by side into connected state
After row attachment (attach) just network slice information can be obtained from network side entity such as AMF.Also, in presently relevant third
For in partner program (3GPP, 3rd Generation Partnership Project) standard Rel-15 version, physics
It is not supported directly between random access channel (PARCH, Physical Random Access CHannel) and network slice yet
Mapping, therefore, UE passing through PRACH carry out wireless heterogeneous networks (RRC, Radio Resource Control) Signalling exchange
During also can not carry out ACB for different network slices based on PRACH.
For the elaboration of above-mentioned network of relation slice mechanism, it can learn: for the UE of IDLE state, can not be cut in conjunction with network
The information of piece (slice) carries out ACB.Reason for this is that:
Firstly, slice information and PARCH resource are difficult to establish corresponding relationship, RACH resource itself is very limited, and support
Slice is possible to very much, and therefore, the PARCH of difference slice can not be based on different random access channel (RACH, Random
Access CHannel) parameter progress ACB.
Secondly as existing for identifying network slice selection auxiliary information (NSSAI, the Network of network slice
Slice Selection Assistance Information) it is longer, including service and slice type (SST, Service
And Slice Type) information and service and slice distinguish (SSD, Service and Slice Differentiator), SST
Reach 32 bits with the total length of both SSD, and each UE can support 8 network slices parallel at present, therefore, network is cut
The total length longest of the identification information NSSAI of piece can achieve byte, considerably beyond common control channel (CCCH, Common
Control Channel) on channel for the limitation of 48 bits set by third class message (MSG3).Therefore, it is impossible to be based on
MSG3 implements ACB for network slice.It is such then will lead to following situations: if some network slice has overloaded
Overload, the then MSG3 sent in UE, such as RRC connection request (RRC Connection Request) message or RRC
Connection restore (RRC Connection Resume) message in can not bearer network slice information, not so as to cause network side
It can be sliced according to the network of overload and refuse the request, and be to continue with and reply the 4th class message (MSG4), for example RRC connection is established
(RRC Connection Establishment) message；UE send the 5th class message (MSG5) receiving the subsequent supervention of MSG4,
And network slice mark is carried in MSG5；Heretofore, network side could be sliced mark according to network and carry out ACB, find net
After network slice overload, network side can be by the RRC Connection Release release of terminal.In this course, UE and network side it
Between interaction MSG4 and subsequent MSG5 may be considered the consumption for increasing signal resource, cause It is not necessary to signaling
The wasting of resources.
Access control is carried out for network slice before in order to send compared with MSG5, provides one in the embodiment of the present invention
The method of kind access control, this method can be applied to UE, and referring to fig. 2, this method may include:
S201:UE and network side equipment are established the piece mark (SSI, Shortened Slice Index) that is chopped and are cut with network
Piece selects the mapping relations between auxiliary information NSSAI；Wherein, the chopped piece mark SSI with mapping relations and network are sliced
Selection auxiliary information NSSAI indicates identical network slice；And the SSI is shorter in length than the NSSAI；
The SSI that target network is sliced is carried in uplink signaling by S202:UE based on the mapping relations；
S203:UE sends the uplink signaling for carrying the SSI of target network slice；Wherein, the uplink signaling is used for institute
It states network side equipment and access control is carried out for target network slice based on the SSI.
Based on technical solution shown in Fig. 2, UE is set with network side equipment, such as access device (such as gNB) or core net
Standby (such as AMF) is established after the mapping relations for completing to be chopped between piece mark SSI and network slice selection auxiliary information NSSAI,
When UE is in free time IDLE state or inactive INACTIVE state, the shorter SSI of length can be carried on uplink signaling (such as
Third class message MSG3) in network side equipment send so that network side equipment is able to use the SSI received and cuts for network
Piece carries out access control.Compared to presently relevant technology, when can make network slice overload, network side equipment is not necessarily to until connecing
ACB can be carried out for network slice according to the NSSAI that MSG5 is carried later by receiving MSG5, can be in advance for network slice
Carry out ACB.Signal resource consumption is not only reduced, avoids the waste of signal resource between UE and network side, and also reduce
The time delay of access control is carried out for network slice.
For technical solution shown in Fig. 2, during specific implementation, network side equipment both may include wireless access network
Equipment, such as gNB；It also may include equipment of the core network, such as AMF；Therefore, the uplink signaling may include RRC signaling or NAS letter
It enables.Specifically, in the case that UE is in free time IDLE state or inactive INACTIVE state, access control is carried out by gNB, because
This, uplink signaling specifically can be RRC signaling, including MSG3 or the 5th class message (MSG5) or other RRC informations；When by
AMF carries out access control, and uplink signaling specifically can be NAS signaling at this time.
In a kind of possible implementation for scheme shown in Fig. 2, it is preferable that for UE described in step S201 with
Network side equipment establishes the mapping relations being chopped between piece mark SSI and network slice selection auxiliary information NSSAI, can wrap
It includes:
UE sends registration request to network side equipment；It wherein, include that network to be registered is sliced letter in the registration request
Breath；
UE receives the registration that network side equipment is returned for the network slice information to be registered in the registration request
It receives the response；Wherein, described to register the mapping relations receiveed the response between NSSAI and SSI including network slice to be registered.
By above-mentioned implementation preferably, network side equipment can it is expected the network slice information of registration according to terminal
The corresponding relationship between NSSAI and SSI is established, and the corresponding relationship is back to UE.Cause to build in the side UE and network side
Found the mapping relations between identical SSI and NSSAI so that UE indicated by SSI target network slice when, net
Network side apparatus can know that target network is sliced by carrying the uplink signaling of SSI, and the load being sliced according to target network
Situation carries out access control.
In addition, being also based on the mesh after UE knows the mapping relations between chopped piece mark SSI and NSSAI
The SSI of mark network slice is directed to target network indicated by SSI by determining whether to carry the uplink signaling of SSI described in transmission
Network slice carries out access control.
For example, for UE after generating the MSG3 for carrying the SSI of target network slice, UE can pass through target network
The SSI of slice decides whether that the mode for sending uplink signaling carries out access control to be sliced to target network.For example, UE can be
According to the priority of SSI, then decides whether to send according to probability and carry the MSG3 of SSI, the probability and corresponding access style
It is related.
