The user may send a service reservation request to the network slice reservation apparatus 100 through the terminal 500, and the terminal 500 may send a service reservation request to the network slice reservation apparatus 100 in a wired or wireless manner.

In some embodiments, the network slice reservation apparatus 100 classifies, plans, and generates a slice configuration process for a group of users received from the service requests of one or more users, so as to avoid a large amount of network signaling caused by executing the service requirements of a single user. , reducing signaling overhead and improving network utilization. Among them, the user's service request can be sent through the terminal.

In some embodiments, the network slice reservation apparatus 100 generates a reservation template according to parameters provided by the user after receiving the service reservation request initiated by the user. The parameters provided by the user include service identifier, service type, reservation time and reservation location, and the reservation time includes reservation start time and reservation end time. The reservation location is the geographic location where the user uses the slice.
