Abstract
In a wireless communication network, a Gateway Control Plane (GW-C) receives a session request for a User Equipment (UE) from an Access Point (AP) that serves the UE. The GW-C transfers a DNS request having an AP ID and network data. A Domain Name System (DNS) translates the AP ID and the network data into an AGW-U ID and an EGW-U ID for co-located GW-Us. The GW-C receives a DNS response and transfers GW control signals using the AGW-U ID and the EGW-U ID. The co-located AGW-U and EGW-U serve the UE responsive to the control signals. In some examples, the selected AGW-U and EGW-U are co-located at the network edge near the AP.
Claims20
A method of operating a wireless communication network to serve User Equipment (UE) over co-located Access Gateway User Planes (AGW-Us) and External GW User Planes (EGW-Us), the method comprising:
- a Gateway Control Plane (GW-C) receiving a session request for the UE from an Access Point (AP) that is wirelessly serving the UE and responsively transferring an AGW-U request that has network data and an AP Identifier (ID) for the serving AP;
- a Domain Name System (DNS) receiving the AGW-U request, translating the AP ID and the network data into an AGW-U ID for one of the AGW-Us, and transferring an AGW-U response that has the AGW-U ID;
- the GW-C receiving the AGW-U response and transferring an EGW-U request that has the network data and the AGW-U ID;
- the DNS receiving the EGW-U request, translating the AGW-U ID and the network data into an EGW-U ID for one of the EGW-Us that is co-located with the one of the AGW-Us based on a location ID, and transferring an EGW-U response that has an EGW-U ID for the co-located one of the EGW-Us;
- the GW-C receiving the EGW-U response and responsively transferring AGW-U control signals using the AGW-U ID and transferring EGW-U control signals using the EGW-U ID;
- and
- the one of the AGW-Us serving the UE responsive to the AGW-U control signals and the co-located one of the EGW-Us serving the UE responsive to the EGW-U control signals.
A wireless communication network to serve User Equipment (UE) over co-located Access Gateway User Planes (AGW-Us) and External GW User Planes (EGW-Us), the wireless communication network comprising:
- a Gateway Control Plane (GW-C) configured to receive a session request for the UE from an Access Point (AP) that is wirelessly serving the UE and responsively transfer an AGW-U request that has network data and an AP Identifier (ID) for the serving AP;
- a Domain Name System (DNS) configured to receive the AGW-U request, translate the AP ID and the network data into an AGW-U ID for one of the AGW-Us, and transfer an AGW-U response that has the AGW-U ID;
- the GW-C configured to receive the AGW-U response and transfer an EGW-U request that has the network data and the AGW-U ID;
- the DNS configured to receive the EGW-U request, translate the AGW-U ID and the network data into an EGW-U ID for one of the EGW-Us that is co-located with the one of the AGW-Us based on a location ID, and transfer an EGW-U response that has an EGW-U ID for the co-located one of the EGW-Us;
- the GW-C configured to receive the EGW-U response and responsively transfer AGW-U control signals using the AGW-U ID and transfer EGW-U control signals using the EGW-U ID;
- and
- the one of the AGW-Us configured to serve the UE responsive to the AGW-U control signals and the co-located one of the EGW-Us configured to serve the UE responsive to the EGW-U control signals.
