Abstract
A first network node connects to a Next Generation Mobile network, such as a Fifth Generation (5G) New Radio (NR) network, and receives, from a user equipment, an attach request that additionally includes a Voice over Long Term Evolution (VoLTE) attach request. The first network node performs a procedure, including signaling, to enable the user equipment to connect to the Next Generation Mobile Network; and signals a second node in a VoLTE Network co-located with the Next Generation Mobile network to attach the user equipment in the VoLTE network.
Claims20
A method, comprising:
- receiving, from a user equipment at a first node in a Next Generation Mobile Network, an attach request that additionally includes a Voice over Long Term Evolution (VoLTE) attach request;
- performing a procedure, including signaling, by the first node in response to receiving the VoLTE attach request, to enable the user equipment to connect to the Next Generation Mobile Network;
- and
- signaling, by the first node in response to receiving the VoLTE attach request, a second node in a VoLTE Network, to attach the user equipment in the VoLTE network.
A first network node, comprising:
- a communication interface connected to a Next Generation Mobile network;
- and
- a processing unit configured to:
- receive, from a user equipment via the communication interface, an attach request that additionally includes a Voice over Long Term Evolution (VoLTE) attach request;
- perform, in response to receiving the VoLTE attach request, a procedure, including signaling, to enable the user equipment to connect to the Next Generation Mobile Network;
- and
- signal, in response to receiving the VoLTE attach request, a second node in a VoLTE Network, co-located with the Next Generation Mobile network, to attach the user equipment in the VoLTE network.
A non-transitory storage medium storing instructions executable by a first network device of a Next Generation Mobile network, wherein the instructions comprise instructions to cause the first network device to:
- receive, from a user equipment, an attach request that additionally includes a Voice over Long Term Evolution (VoLTE) attach request;
- perform, in response to receiving the VoLTE attach request, a procedure, including signaling, by the first network device, to enable the user equipment to connect to the Next Generation Mobile Network;
- and
- signal, in response to receiving the VoLTE attach request, a second network device in a VoLTE Network, to attach the user equipment in the VoLTE network.
