Abstract
A method for determining an access point name (APN) for mission critical services includes determining, at a user equipment (UE), APN information of a packet data network (PDN) based on at least one of a mission critical organization name, a registered public land mobile network identifier, or a home public land mobile network identifier currently associated with the UE; and connecting to the PDN based on the determined APN information.
Claims10
A user equipment (UE) comprising:
- at least one hardware processor;
- and
- a non-transitory computer-readable storage medium coupled to the at least one hardware processor and storing programming instructions for execution by the at least one hardware processor, wherein the programming instructions, when executed, cause the UE to perform operations comprising:
- sending, by the UE to a first network node, a first message including at least one mission critical user identity associated with the UE;
- receiving, from the first network node, a second message indicating that the UE can request access point name (APN) information of a packet data network (PDN) for mission critical services;
- sending, by the UE to a second network node, a third message requesting the APN information;
- and
- receiving, from the second network node, a fourth message including the APN information, wherein the first network node and the second network node are an identity management server, the first, second, third and fourth messages are sent or received via an identity management client in the UE, and the first, second, third and fourth messages are authentication messages.
A non-transitory computer-readable medium storing instructions which, when executed, cause a computing device to perform operations comprising:
- sending, by a user equipment (UE) to a first network node, a first message including at least one mission critical user identity associated with the UE;
- receiving, from the first network node, a second message indicating that the UE can request access point name (APN) information of a packet data network (PDN) for mission critical services;
- sending, by the UE to a second network node, a third message requesting the APN information;
- and
- receiving, from the second network node, a fourth message including the APN information, wherein the first network node and the second network node are an identity management server, the first, second, third and fourth messages are sent or received via an identity management client in the UE, and the first, second, third and fourth messages are authentication messages.
