In practice, the management equipment of network slice can be sliced network and be adjusted, for example, network administrator passes through pipe Reason equipment deletes certain network slice, so that whole user equipmenies in network slice can be offline, then accesses other networks again Slice；Policy control center will have already accessed to some or all of some network slice according to preconfigured strategy automatically User equipment is offline, so that these user equipmenies are linked into other networks slice again；Intellectual analysis center is real-time according to network Load, adjust automatically have already accessed to some or all of some network slice user and are linked into other networks slice again.

In order to avoid user equipment is after detecting that itself is offline, it is sliced repeatedly to network and sends access request, lead to net Network burden suddenly become weight situation, present embodiments provide it is a kind of access network slice method, can to network be sliced into When row adjustment, orderly other networks of the access slice of control user equipment, realization reduces network burden in migrated users equipment, Avoid influencing the transmission of normal business datum.This method can be sliced by network, management equipment and user equipment are realized jointly, First network slice in the present embodiment is sliced for the network for needing user equipment to access again, and the second network slice sets for user The standby network slice being currently accessed.As shown in fig. 6, the process flow of this method can be as follows：

Step 601, management equipment receives user and migrates instruction.

Wherein, user migrates the second network slice that the migration process in need for carrying out user equipment can be carried in instruction Mark and user equipment need to access again first network slice mark.

In an implementation, the received user of management equipment, which migrates instruction, can be what the operation based on network administrator generated, It is also possible to be sliced what management strategy generated based on preset network.For example, management equipment can be slice management system, network Administrator can carry out user equipment migration operation in slice management system, and selection needs to carry out the migration process of user equipment Network slice (i.e. the second network slice) and user need to access again first network slice, then selection migration select , management equipment then can receive the user and migrate instruction；Alternatively, management equipment can be policy control center, strategy control Center processed can determine the second network slice for needing to be adjusted, and need user equipment according to preconfigured strategy Again the first network slice accessed, and then generate user and migrate instruction；Alternatively, management equipment can also be in intellectual analysis The heart, intellectual analysis center can determine first network slice and the second network slice, to generate use according to network real-time load Family migration instruction.

Step 602, management equipment is sliced to the second network and sends user's announcing removal.

In an implementation, management equipment can be migrated according to user and be instructed, and be sliced to the second network and sent user's announcing removal, The mode for sending user's announcing removal can be diversified, present embodiments provide two kinds of feasible processing modes.

Mode one sends the user's announcing removal for carrying the mark that first network is sliced to the second network slice.

In an implementation, the available user of management equipment migrates the mark of the first network slice in instruction, then basis The mark of first network slice, generates user's announcing removal, which is sent to the second network slice, so that the Two networks slice is by the user equipment migration locally accessed into first network slice.In addition, for will be in the second network slice Certain customers' equipment transportation to first network be sliced the case where, management equipment can also according to the operation of network administrator, or The preset network of person is sliced management strategy, determines the user equipment migrated, can also take in user's announcing removal The quantity of mark and/or user equipment with the user equipment in need migrated, the quantity can be migration number, can also To be percentage.

The corresponding relationship of mode two, the mark of network according to the pre-stored data slice and NSSAI determines that first network is sliced The corresponding NSSAI of mark；The user's announcing removal for carrying the NSSAI that first network is sliced is sent to the second network slice.

In an implementation, the mark of network slice and the corresponding relationship of NSSAI can also be stored in advance in management equipment, In, different networks is sliced corresponding NSSAI and is different.The corresponding relationship can be as shown in Table 1：

Table one

NSSAI	Network slice
		1111	A
2222	B
		3333	C

Wherein, A, B, C are respectively the mark of network slice.

After management equipment gets the mark of first network slice, it can search first network in the corresponding relationship and cut It is logical to generate user's migration by the corresponding NSSAI of the mark of piece, the corresponding NSSAI of mark that then can be sliced according to first network Know, which is sent to the second network slice, so that the second network slice moves the user equipment locally accessed It moves on in first network slice.In addition, for certain customers' equipment transportation in the second network slice is sliced to first network The case where, management equipment can also be sliced management strategy according to the operation of network administrator or preset network, determine and need The user equipment migrated can also carry the mark of the user equipment in need migrated in user's announcing removal And/or the quantity of user equipment, the quantity can be migration number, is also possible to percentage.

Step 603, the second network slice receives user's announcing removal that management equipment is sent.

Step 604, the second network slice obtains first network and is sliced the auxiliary information that corresponding network is sliced selection NSSAI。

Wherein, first network slice is the network slice that the user equipment migrated needs to access again

In an implementation, the second network slice can obtain first network slice pair according to the user's announcing removal received The NSSAI answered.The step can have following two processing mode：

Mode one obtains the corresponding NSSAI of first network slice carried in user's announcing removal.

In an implementation, for carried in above-mentioned user's announcing removal first network slice NSSAI the case where, the second net Network slice can parse user's announcing removal, obtain the NSSAI of first network slice.The NSSAI can be deposited in advance The NSSAI of the first network slice of storage is also possible to the NSSAI for the first network slice that network administrator newly increases.If the Two networks slice detects in the mark of network slice and the corresponding relationship of NSSAI being locally stored, and the NSSAI is not present, then The mark of first network slice and the NSSAI can be added in the corresponding relationship.For example, the network slice being locally stored Shown in the corresponding relationship table one as above of mark and NSSAI, the second network slice receives the corresponding NSSAI 4444 of network slice B Afterwards, B and 4444 can be added in the mapping table, as shown in chart two：

Table two

Alternatively, the NSSAI may be the NSSAI of the second network slice, then the second network slice can be somebody's turn to do in table one The mark of the corresponding network slice of NSSAI, is revised as the mark of first network slice.For example, the user that network slice A is received In announcing removal, the first network of carrying is sliced B and NSSAI 1111, then can be by the mark of 1111 corresponding network slices Knowledge is revised as B, as shown in Table 3：

Table three

NSSAI	Network slice
		1111	B
2222	B
		3333	C

Mode two, the mark for obtaining the first network slice carried in user's announcing removal, network according to the pre-stored data The mark of slice and the corresponding relationship of NSSAI, determine the corresponding NSSAI of mark of first network slice.

In an implementation, for carried in user's announcing removal first network slice mark the case where, the second network is cut The mark of network slice and the corresponding relationship of NSSAI can be stored in advance in piece, which is referred to above-mentioned table one.The Two networks slice can parse user's announcing removal, the mark of first network slice be obtained, then in the corresponding relationship In, search the corresponding NSSAI of mark of first network slice.

In practice, if the second network slice needs to be deleted, management equipment can be sliced to the second network and send User's announcing removal of the mark of first network slice is carried, carries first alternatively, can be sliced to send to the second network User's announcing removal of the NSSAI of network slice, so that the second network is sliced local whole user equipment migrations to first In network slice.If only the certain customers that the second network hits moved in first network slice, the second network slice It also needs to continue to use, first network can be carried to the slice transmission of the second network and be sliced corresponding newly-increased NSSAI.

The processing of this step can be sliced by network in SSF realize.

Step 605, the second network is sliced to user equipment and sends the corresponding NSSAI of first network slice, and first network is cut The corresponding NSSAI of piece is used to indicate user equipment access first network slice.
