Admission of a session to a virtual network service
First Claim
1. A method of admitting a user session to a virtual network, the method comprising:
- receiving, at a mobility management function in a core network domain, an attach request from a User Equipment associated with the virtual network;
transmitting an instruction, from the mobility management function towards the User Equipment, to begin an authentication challenge with an Authentication Function, the Authentication function both associated with and resident within the virtual network which is both associated with the User Equipment and distinct from the core network; and
transmitting, by the mobility management function, an instruction to admit the user equipment to a user session in the virtual network in response to receipt of an indication of successful completion of the authentication challenge.

Abstract
An aspect of the disclosure provides a method of admitting a session from a user device subscribed to a service with a virtual network operator. The method includes receiving a service request from said user device at an Access Point and selecting a network function Authentication and Authorization (AA) function (AAF) to confirm the user device is authorized for the requested service, and transmitting the request to the selected network function AAA function. The AAAF which processes the request may reside with the virtual network operator (VNO). However, the VNO may share its AAA database with other network entities (for example, Telecom Connectivity Service Providers (TCSPs) or InPs), and allow those entities to perform the AAA functions.

17. A mobility management function in a core network domain for admitting a user session in a virtual network, the mobility management function comprising:
-
a network interface; a processor; and a machine readable memory storing machine executable instructions which when executed by the processor configure the mobility management function to; receive an attach request from a User Equipment associated with the virtual network over the network interface; transmit an instruction, from the mobility management function towards the User Equipment over the network interface, to begin an authentication challenge with an Authentication Function, the Authentication Function both associated with and resident within the virtual network which is both associated with the User Equipment and distinct from the core network; and transmit over the network interface, an instruction to admit the user equipment to a user session in the virtual network in response to receipt of an indication of successful completion of the authentication challenge. - View Dependent Claims (18, 19, 20, 21)
