In embodiments of the present invention, specifically the network slice base station 1, RAN 2 is supported to support that network slice 2 is with the base station RAN 1
Example.
In should actually applying, the network slice that UE is pre-configured is also possible that a RAN base station neighbouring with the base station RAN 1
The network of support is sliced, it is also possible to which the network including supporting with the neighbouring multiple base stations RAN in the base station RAN 1 is sliced, for example, UE is pre-
The network slice of configuration includes the network slice 2 for the network slice support of the base station 1 and RAN 2 that the base station RAN 1 is supported；For another example, UE is pre-
The network of network slice 1, the support of the base station RAN 2 that the network slice of configuration is supported including the base station RAN 1 is sliced the base station 2 and RAN 3
Network slice 3 of support etc..
In embodiments of the present invention, the network slice 1 supported including the base station RAN 1 is specifically sliced with the network that UE is pre-configured
For the network slice 2 supported with the base station RAN 2.
So, when the cell of the base station RAN 1 to be resided in UE, UE will initiate to register to the base station RAN 1, meanwhile, UE
The network slice 1 and network slice 2 of pre-configuration can be carried, in practical applications, UE can pass through msg5 message in registration process
In RRC in S-NSSAI information carry be pre-configured network slice 1 and network slice 2.
The base station RAN 1, according to the S-NSSAI information in msg5 message in RRC, obtains UE and takes after receiving msg5 message
The network slice 1 and network slice 2 of the pre-configuration of band.
Optionally, what the CN obtained that the UE carries in the first RAN base station login belongs to the first RAN base
The network supported of standing is sliced, and the CN is sent to the first base station RAN indicates that the CN receives the first base station RAN and supports
Network slice Allowed S-NSSAI information.
In embodiments of the present invention, the base station RAN 1 obtain UE carry pre-configuration network slice 1 and network slice 2 it
Afterwards, the network slice 1 that the base station RAN 1 can be supported and the network slice 2 that it is not supported but neighbor base station is supported are sent
To CN, so that CN obtains the network slice for the pre-configuration that UE is carried namely network is sliced 1 and network slice 2.
Step S102: the CN sends the information for indicating that the network that the CN receives is sliced, institute to the first base station RAN
Dual link DC of the information for the first base station RAN foundation and the 2nd base station RAN is stated, so that the UE is obtained by the DC
Obtain the service of the network slice.
Wherein, the 2nd base station RAN is the base station for supporting the network slice.
In this law inventive embodiments, after the pre-configured network slice 1 and network slice 2 that CN obtains that UE is carried, CN
The network slice list for the network slice that the neighbor base station including the base station RAN 1 that can be sent according to the base station RAN 1 is supported, determines
The network slice that network slice 1 is supported for the base station RAN 1, and determine that network slice 1 is not that single neighbor base station is supported in the base station RAN 1
Namely the network slice that the base station RAN 2 is supported.
The base station RAN 1 can send above-mentioned network slice list to CN when NG interface is established, and the base station RAN 1 can also be at it
When configuration updates, above-mentioned network slice list is sent to CN.
Optionally, the base station RAN 1 can be supported according to the neighbor base station for the network slice and the base station RAN 1 that this base station is supported
Network slice, form network a slice list TAI Slice Support List, a network slice list TAI
It just include the network slice that this base station is supported and the network slice that neighbor base station is supported in Slice Support List.
For example, RAN1 indicates the base station RAN 1 in Fig. 3 shown in Fig. 3, RAN2 indicates the base station RAN 2,5G-CN table in Fig. 3 in Fig. 3
Show CN, the base station RAN 1 sends network slice list TAI Slice Support List, CN to CN when NG interface is established and connecing
After receiving TAI Slice Support List, the information of carrying AMF TAI Slice Support List can also be passed through
The base station RAN 1 is responded, specifically, CN can be carried in the information that the NG interface for responding the base station RAN 1 is established as shown in Figure 3
AMF TAI Slice Support List。
Optionally, the network that the base station RAN 1 can also be supported according to this base station is sliced, and the network that group cost base station is supported is cut
Piece list TAI Slice Support List, and be sliced according to the network that the neighbor base station of the base station RAN 1 is supported, composition is adjacent
The network slice list DC TAI Slice Support List that nearly base station is supported, then, TAI Slice Support List
The network slice of the support of the base station RAN 1 is just only included, DC TAI Slice Support List just only includes neighbor base station support
Network slice.
Likewise, the base station RAN 1 can will only include the base station RAN 1 when NG interface is established or when its configuration updates
The TAI Slice Support List for the network slice the held and DC TAI for only including the network slice that neighbor base station is supported
Slice Support List occurs to CN, and CN can be by carrying AMF TAI Slice Support List and AMF DC
The message of TAI Slice Support list to the base station RAN 1 has received TAI Slice Support List and DC
TAI Slice Support List。
In embodiments of the present invention, specifically being sent when NG interface is established to CN with the base station RAN 1 includes what this base station was supported
For the network slice list TAI Slice Support List for the network slice that network slice and neighbor base station are supported.
In practical applications, above-mentioned steps S102 can at least be executed according to following three kinds of modes:
First way:
Step A: the CN sends the information for indicating that the network that the CN receives is sliced to the first base station RAN.
With continued reference to FIG. 3, CN can store the network slice supported including the base station RAN 1 and neighbor base station received
The TAI Slice Support List of the network slice of support, cuts in the network that the base station RAN 1 carries UE in registration process
When piece 1 and network slice 2 are sent to CN, CN can determine network slice 1 according to the TAI Slice Support List of storage
Belong to the network slice of the support of the base station RAN 1, and determines that network slice 2 is not belonging to the support of the base station RAN 1 but neighbor base station branch
The network slice held.
CN can directly respond the Allowed S- for receiving network slice 1 and receiving network slice 2 to the base station RAN 1
NSSAI information, so UE by the base station RAN 1 to CN network slice 2 initiate service PDU (Protocol Data Unit,
Protocol Data Unit) when establishing, CN can be responded to the base station RAN 1 receive the PDU of UE and establish, and then the base station RAN 1 can be returned to UE
The PDU that should receive UE is established, meanwhile, the base station RAN 1 can initiate and support the base station RAN 2 of network slice 2 for the foundation of the PDU
Between dual link DC foundation, and then the DC by establishing completes the foundation of the PDU, so that UE obtains the clothes of network slice 2
Business.
It should actually apply, can also exist when reasons such as base station cell poor signal qualities, it is also possible to cause DC to establish failure,
Cause the PDU of UE to establish the case where being rejected, does not just do excessive discussion herein.
So including the network slice for being not belonging to support same base station in the network slice that UE is carried by the above method
When, CN can directly receive the network for being not belonging to support same base station slice, and the base station RAN that UE is registered should with support
DC is established in the adjacent area base station RAN of network slice, so that UE obtains the service that the network is sliced by the DC, so, it is effective to solve
It has determined in the prior art, existing UE can not obtain the service for the network slice for being not belonging to support same base station, realize that UE is obtained
It is not belonging to the purpose of the service of the network supported same base station slice.
Since network slice 1 is supported in the base station RAN 1, so, clothes are initiated in network slice 1 to CN by the base station RAN 1 in UE
When business PDU is established, CN directly responds the PDU foundation for receiving UE to the base station RAN 1, and then the base station RAN 1 also receives and completes UE
The PDU establish so that UE obtain network slice 1 service.
The second way:
Step B: the CN sends the information for indicating that the network slice of the CN receiving can make DC to the first base station RAN.
In second method, CN receives the network including the network slice supported of the base station RAN 1 and neighbor base station support
When the TAI Slice Support List of slice, according to TAI Slice Support List, determine that network slice 1 belongs to
The base station RAN 1 support network slice, and determine network slice 2 be not belonging to the base station RAN 1 support but neighbor base station support
Network slice.
Due to the slice that network slice 1 is supported for the base station RAN 1, CN, which can be responded directly to the base station RAN 1, receives network
Slice 1 Allowed S-NSSAI information, UE by the base station RAN 1 to CN network slice 1 initiate service PDU establish when,
CN can respond the PDU foundation for receiving UE to the base station RAN 1, and then the base station RAN 1 is built to the PDU that UE responds receiving and completes UE
It is vertical, so that UE obtains the service of network slice 1.
And network slice 2 is not belonging to the slice that the base station RAN 1 is supported but neighbor base station namely the base station RAN 2 are supported, CN can
The Allowed S-NSSAI information of DC can be done directly to receive network slice 2 to the response of the base station RAN 1, and then passes through RAN in UE
To CN when 2 initiation service PDU of network slice is established, CN responds the PDU foundation for receiving UE, RAN base to the base station RAN 1 for base station 1
The PDU that 1 can receive UE to UE response that stands is established, meanwhile, the base station RAN 1 can initiate and support network slice for the foundation of the PDU
The foundation of dual link DC between 2 base station RAN 2, and the DC by establishing completes the foundation of the PDU, so that UE obtains network
The service of slice 2.
So including the network slice for being not belonging to support same base station in the network slice that UE is carried by the above method
When, CN can receive network slice in a manner of supporting the network to be sliced as DC, make and then obtain the base station RAN of UE registration
DC can be established with the adjacent area base station RAN of network slice is supported, so that UE obtains the service that the network is sliced, institute by the DC
In the prior art with, effective solution, existing UE can not obtain the service for the network slice for being not belonging to support same base station,
Realize that UE obtains the purpose of the service for the network slice for being not belonging to support same base station.
The third mode:
The CN obtains the finger for being used to indicate the network slice and can making DC and being allowed to receiving that the first base station RAN is sent
Show information；
For the CN according to the instruction information, the network slice for sending receiving can make the information of DC.
Referring to FIG. 4, RAN1 indicates the base station RAN 1 in Fig. 4, RAN2 indicates the base station RAN 2 in Fig. 4, and 5G-CN is indicated in Fig. 4
The base station CN, RAN 1 obtain UE registration (namely initial access in Fig. 4) when be pre-configured network slice 1 and network slice 2 it
Afterwards, the network slice that the network slice and neighbor base station that the base station RAN 1 can first be supported according to this base station being locally stored are supported
Information determines that network slice 2 is not belonging to the network slice that the base station RAN 1 is supported but the neighbouring base station RAN 2 is supported, the base station RAN 1 exists
Instruction CN network slice 2 is carried in the UE initial information sent to CN can be used as the instruction information that DC is allowed to receiving.
CN receive carried in UE initial information instruction network slice 2 can be used as DC be allowed to receive instruction information it
Afterwards, CN, which receives network slice 2 to the response of the base station RAN 1, can be used as the information of DC, and then after the completion of UE registration, UE passes through RAN
To CN when network slice 2 initiates service PDU establishment process, CN responds the PDU foundation for receiving UE to the base station RAN 1 for base station 1,
The base station RAN 1 responds the PDU foundation for receiving UE to UE, and the foundation that the base station RAN 1 is the PDU is initiated to be sliced 2 with network is supported
