Meanwhile, with the continuous development and update of communication technology, broadband services are also developed in the directions of integration, digitization, intelligence and virtualization, and the OLT is the core device of the PON system, is responsible for the comprehensive access function of various services such as common broadband users, government and enterprise users and provides various services such as broadband, video, voice, private line and the like. The OLT network slicing technology considers the OLT physical equipment as an open platform, one equipment is divided into a plurality of network slices, each slice has an independent management object, a hardware table entry and a user management interface, services of different slices are isolated, and no influence is caused between the different slices. Of course, the above functions are realized, and problems of inconvenience in user migration between slices, multiple operation steps, increase in operation and maintenance difficulty, and the like are also brought.
After the OLT is divided into a plurality of logical network slices, the following problems exist in the aspect of configuration migration:
the OLT uses the network slice to face the current virtualized network reconstruction, and different slices of the same physical OLT are different management domains and configuration domains;
in a multi-slice scenario, each slice is virtualized into an independent network element with independent service configuration. The user may create a separate business template for each slice and bind to objects within the slice. These templates are independent of each other and are only valid in the region of action of the slice;
because the ONU object is bound with the local template of the slice, if configuration needs to be reserved during migration, the corresponding template binding relationship needs to be reserved. Because the templates are independent in the slices, the conventional scheme considers cross-slice template replication, and the scheme has high processing overhead during migration, easily causes configuration redundancy, occupies equipment memory and brings great inconvenience to maintenance work.

The system of claim 6, wherein the configuration management module further comprises a template deletion unit to: when the slicing network element deletes the template entry, judging whether only the bit corresponding to the network slice in the bitmap in the template entry is available, and other bits are all unavailable:
if yes, checking the binding relationship in the object of the network slice, and if no other object is bound to the template item, deleting the template content;
if not, checking the binding relationship in the object of the network slice, if no other object binds the template, marking the corresponding bit of the network slice in the bitmap of the template entry as unavailable, and not modifying other bits.
