Embodiment Construction

[0056] The general 5G core network architecture serving UE's 3GPP access and N3GPP access has been described above.

[0057] figure 2 Also shown is a simplified CN architecture in a roaming situation, ie where a subscriber accesses a CN that is not its home PLMN. The UE registers with the AMF in the visited network similarly as described above, but the AMF contacts the home network for authentication. The UDM and AUSF in the home network authenticate the UE and create a security context that is transferred to the AMF in the visited network.

[0058] According to the new CN architecture of 5G, the UE can simultaneously access the visited PLMN via 3GPP access, access the home PLMN via N3GPP, eg via the Internet via WLAN. N3GPP access is then provided via the N3IWF of the Home PLMN and a second registration is made at the AMF in the Home PLMN.

[0059] The first embodiment is based on the figure 2 The general architecture of , ie, it is assumed that the UE is camped at a lo...

Abstract

The present invention provides a method capable of providing a Public Warning System PWS message to a user equipment UE device via a non-3GPP radio network, the method comprising: establishing an Internet from the UE device to a non-3GPP interworking function N3IWF via a non-3GPP N3GPP radio access technology A protocol security IPSec tunnel connection, requesting to provide a public warning system PWS message to the first CN entity; providing information about the location of the UE device to the first CN entity.

Description

technical field [0001] The present invention relates to a mechanism for distributing common alert messages when a user equipment device is attached to a non-3GPP network. Background technique [0002] A user equipment (UE: user equipment) device usually accesses a 3GPP core network (CN: core network) through an access network that may be a radio access network (RAN: radioaccess network). If the radio access network is defined by 3GPP, for example by the newly defined 5G radio access network, this access network provides a connection to an authentication and mobility function (AMF: authentication and mobility function). AMF can occur multiple times in a single CN. An AMF is usually selected for a UE when it registers in the network, and only one AMF is responsible for a single UE. Like all elements of CN, AMF can communicate with other CN elements through routing infrastructure. For example, the AMF is connected to Universal Data Management (UDM) to authenticate the UE at ...
