         9 . The network device according to  claim 8 , the processor is further configured to execute the instructions to cause the network device to: determine the at least one service type and respective identifier of at least one network slice supporting the at least one service type , wherein the at least one network slice comprises the first network slice. 
     
     
         10 . The network device according to  claim 8 , the processor is further configured to execute the instructions to cause the network device to: receive from a network slice, an identifier of the network slice and at least one service type supported by the network slice. 
     
     
         11 . The network device according to  claim 8 , wherein the network device is a management device for managing at least one network slice. 
     
     
         12 . The network device according to  claim 8 , wherein the service type comprises: a mobile broadband service, a vehicle to vehicle communication service, a machine type communication service, an ultra-low delay service, a super-high-reliability service, or an Internet Protocol (IP) continuity maintaining service. 
     
     
         13 . The network device according to  claim 8 , the service requirement list of user equipment is configured by a subscriber server. 
     
     
         14 . The network device according to  claim 9 , wherein determining the first identifier of a first network slice to provide a service for the UE comprises:
 determine, according to the service requirement list, and the identifier of the at least one network slice and the at least one service type supported by the at least one network slice respectively, that the at least one service type supported by the first network slice comprises a largest quantity of service types in the service requirement list.   
     
     
         15 . A system, comprising: at least one network slice and a management device for managing at least one network slice, wherein
