Embodiment
Technical scheme provided in an embodiment of the present invention will be solved mainly under Multi net voting slice systems framework, at the beginning of terminal
Network section select permeability in beginning access network process.Below in conjunction with the accompanying drawings to the specific embodiment party of the present invention
Formula illustrates.
Fig. 2 is that core net network is cut into slices to access network visible system configuration diagram, as illustrated, this programme
In system architecture as shown in Fig. 2 physical entity in system architecture includes control face entity, base station or connect
Access point, and terminal.Wherein control face entity can be configured to establish interface with multiple network slice logic functions,
Different network slice logic functions may be configured in CN (Core Network, core net) entity,
The entity that may also be allocated directly in access network domain.Same terminal can be registered to multiple networks simultaneously and cut
Piece, and serviced simultaneously from the section of multiple networks.
Based on above-mentioned framework, in declarative procedure, by respectively from terminal, base station, the reality for controlling face entity side
Apply and illustrate, then will also provide three and coordinate the example implemented to more fully understand in the embodiment of the present invention
The implementation of the scheme provided.Such explanation mode be not meant to three must coordinate implementation or it is necessary
Independent to implement, in fact, when terminal, base station, control face entity are performed separately, it is also each solved certainly
The problem of body side, and triplicity is in use, superior technique effect can be obtained.
Fig. 3 is the initial access method implementing procedure signal that the terminal in terminal is cut into slices in network under framework
Figure, as illustrated, can include：
Step 301, in terminal initial access procedure, determine terminal network section selection information；
Step 302, the connection foundation request for carrying network section selection information is sent to base station in terminal
Message.
In implementation, the terminal target logic network to be accessed can be obtained ahead of time before network is accessed and cut for terminal
The temporary mark information of piece, terminal in access procedure, using the temporary mark that target logic network is cut into slices as
Network section selection information reporting is used for the selection of network section to access network entity.
Fig. 4 is the initial access method implementing procedure signal that the terminal on base station is cut into slices in network under framework
Figure, as illustrated, can include：
Step 401, in terminal initial access procedure, receiving terminal send carry network section selection
Request message is established in the connection of information；
Step 402, for terminal selection provides service control face entity for terminal establish connection.

Selection can be divided into two major class schemes, be respectively：
Op1:Based on the network of base station or access point section selection scheme；
Op2：Network section selection scheme based on control face entity.
For Op1 based in the network of base station or access point section selection scheme, base station or access point are protected in advance
The network slice information that each control face entity is supported is deposited, base station can establish interface mistake with control face entity
Directly it can also pass through webmaster OAM by controlling face entity to obtain the network slice information of its support in journey
System obtains the networking slice information that control face entity is supported.In terminal initial access procedure, base station according to
The network section selection information that terminal reports, and combine the support situation that control face entity is cut into slices to heterogeneous networks
Control face entity is selected for terminal.
For network section selection schemes of the Op2 based on control face entity, base station or access point do not preserve in itself
The network slice information of face entity is controlled, in terminal initiates initial network access procedure, base station will be from terminal
The network section selection information of acquisition is sent to " acquiescence control face entity ", and control face entity judges that itself is
It is no to provide service for the terminal, if acquiescence control face entity can not provide access service for terminal,
Control face entity will be that terminal reselects suitable control face entity.
