System and method for virtualized functions in control and data planes
First Claim
1. A method, in a communication network supporting a plurality of network slices, the method comprising:
- receiving, by a connection and mobility management function, an attach request transmitted by the mobile device, the attach request including an identifier indicative of a network slice of the plurality of network slices; and
transmitting the attach request, from the connection and mobility management function to a service-specific connection and mobility management function associated with the network slice which the identifier is indicative of, to associate the mobile device with the network slice.

Abstract
Methods and apparatus for management of network slices in a communication network such as a 5th generation wireless communication network are provided. Management planes may be provided which are separate from the plurality of network slices. A connection manager residing in a management plane receives an indication that a mobile device is to be associated with the communication network. The connection manager may reside at an access node or in the core network. A network slice is determined, and the connection manager transmits instructions, to one or more network nodes, to associate the mobile device with the network slice. The instructions may be provided to a local connection manager. The slice may be requested explicitly by the mobile device, or determined based on device and/or network requirements.

15. A method, in a communication network supporting a plurality of network slices, the method comprising:
-
receiving, by a connection and mobility management function, an attach request from a mobile device via an access node, the attach request including an identifier indicative of a network slice of the plurality of network slices; determining, by the connection and mobility management function, which network slice of the plurality of networks slices to associate with the mobile device based on the identifier; selecting, by the connection and mobility management function, a service-specific connection and mobility management function associated with the determined network slice; and transmitting a message, from the connection and mobility management function to the access node, to prompt the access node to forward the attach request to the selected service-specific connection and mobility management function, wherein the message comprises the identifier indicative of the network slice and an indication of the selected service-specific connection and mobility management function. - View Dependent Claims (16, 17, 18, 19, 20)
