Abstract
Systems and methods for implementing virtualized functions in control and data planes for a communications network are described herein. A method for managing a User Equipment (UE) attach request includes instantiating a Global Connection and Mobility Management (G-CMM) function configured to operate across a plurality of network slices in the communications network, determining an appropriate network slice from the plurality of network slices with the G-CMM function, and attaching the UE to the appropriate network slice.
Claims26
A method, for execution by an access node (AN) in a mobile network, for attaching a User Equipment (UE) to a network slice, the method comprising:
- receiving a UE attach request from the UE;
- transmitting towards a slice selection function (SSF), an attach request generated in accordance with the UE attach request received from the UE;
- receiving, from the slice selection function, a slice identifier associated with a selected network slice;
- initiating a connection setup including a control plane connection, in accordance with the received slice identifier, between the UE and a control plane network function associated with the selected network slice.
A network access node (AN) operative to attach a connecting User Equipment (UE) to a network slice comprising:
- a network interface for communicating with other nodes connected to a network;
- a wireless access interface for communicating with the UE connecting to the network through the AN;
- a processor;
- and
- a non-transitory memory for storing instructions that when executed by processor,
- the AN operative to:
- receive a UE attach request from the UE;
- transmit towards a slice selection function (SSF), an attach request generated in accordance with the UE attach request received from the UE;
- receive, from the slice selection function, a slice identifier associated with a selected network slice;
- initiate a connection setup including a control plane connection, in accordance with the received slice identifier, between the UE and a control plane network function associated with the selected network slice.
