Abstract

A device may receive relationship information indicating a relationship between first geographic information and a network gateway. The network gateway may be associated with providing a user device with access to a network. The device may store the relationship information. The device may receive, from the user device and via a base station, second geographic information indicating a tracking area in which the user device is located. The device may identify one or more network gateways, associated with the second geographic information, based on the second geographic information and the relationship information. The device may provide, to the user device, one or more device identifiers associated with the one or more network gateways to permit the user device to access the network via the one or more network gateways. The one or more device identifiers may be provided in association with a non-access stratum message.

Dependent claims

A method comprising:

receiving, by one or more devices, geographic information,
the geographic information indicating a coverage area in which a user device is located, and
the one or more devices including one or more server devices having authentication and mobility functions;
determining, by the one or more devices and based on the geographic information, a first packet data gateway (PDG) device and a second PDG device associated with the coverage area;
determining, by the one or more devices, a first priority of the first PDG device based on geographic proximity of a tracking area or a cell of the user device to the first PDG device;
determining, by the one or more devices, a second priority of the second PDG device based on geographic proximity of the tracking area or the cell of the user device to the second PDG device;
determining, before providing a first device identifier that identifies the first PDG device and a second device identifier that identifies the second PDG device, that the user device is configured to use at least one of the first device identifier or the second device identifier to access a core network via the first PDG device or the second PDG device;
and
providing, by the one or more devices and to the user device, the first device identifier, the second device identifier, and information that indicates the first priority of the first PDG device and the second priority of the second PDG device.
