Samsung patents 5G paging method that saves radio resources
Samsung has been granted a patent for a method to handle network paging in 5G systems. The system sends a notification to a phone through a non-cellular connection, like Wi-Fi, if the phone is not connected to a 5G cell tower. If the phone cannot reach the 5G network, it sends a message back saying it cannot respond, which helps save battery and network capacity.
In the filing’s own words
Embodiments herein provide methods and systems for performing paging operation in 5G communication networks. The 5G core network can transmit a NAS message to a UE through a N3GPP access network, if the UE is reachable through the N3GPP access network. The NAS message can be sent by the 5G core network to the N3IWF. The N3IWF can send the NAS message to the UE, through the N3GPP access network. The UE can send a service request over 3GPP access, in response to the NAS message, to the 5G core network, through a 5G RAN. If the UE is not having access to the 5G RAN, then the UE can transmit a notification response message to the 5G core network, indicating the inability to transmit a service request. The transmission of NAS message through the N3IWF can lead to a significant saving of radio resources.
What exactly they claim (claim 1)
1. A method performed by a User Equipment (UE) in a wireless communication system, the method comprising: receiving, from an Access and Mobility Function (AMF), a notification message through a Non-3rd Generation Partnership Project (N3GPP) access network, when the UE is in a CONNECTED mode over the N3GPP access network and in an IDLE mode over a 3GPP access network; and transmitting a notification response message to the AMF through the N3GPP access network in response to the notification message, when the UE is out of coverage in the 3GPP access network, wherein the notification response message indicates inability of the UE to transmit a service request message to the AMF through the 3GPP access network in response to the notification message.
