Patent number: 11864149Abstract: This disclosure combines the Attach and Tracking Area Update procedures into one new mobility procedure: the Registration procedure. One advantage of the proposed Registration procedure is that, if the new SHF is unable to obtain UE data from the old SHF the new SHF will nevertheless register the UE so that the UE does not have to perform another registration procedure (e.g., an Attach procedure).Type: GrantFiled: March 10, 2022Date of Patent: January 2, 2024Assignee: TELEFONAKTIEBOLAGET LM ERICSSON (PUBL)Inventors: Peter Ramle, Josefin Karlsson, Lasse Olsson

Publication number: 20220345941Abstract: A method implemented by a Policy Control Function (PCF) of a Core Network (CN) node in a communications network includes receiving a request message from an Access and Mobility management Function (AMF). The request message includes a requested Data Network Name (DNN) designated by a wireless terminal in a Protocol Data Unit (PDU) session establishment request to the AMF. Responsive to the request message and to session-specific information, a selected DNN and a Session Management Function (SMF) index is determined. Each of one or more SMFs are registered with a Network Repository Function (NRF) of the CN node or a different CN node according to a corresponding SMF profile. The selected DNN and the SMF index are sent to the AMF to facilitate selection of one of the one or more SMFs via the NRF for establishment of the PDU session between the wireless terminal and the selected SMF.Type: ApplicationFiled: December 6, 2019Publication date: October 27, 2022Inventors: Lasse Olsson, Peter Ramle

Publication number: 20220303935Abstract: Systems and methods are disclosed herein for Access and Mobility Function (AMF) re-allocation. In one embodiment, a method for AMF re-allocation includes, at an initial AMF, receiving a registration request for a User Equipment (UE) from a Radio Access Network (RAN), deciding to initiate an AMF re-allocation procedure, sending the registration request to the RAN for delivery to a target AMF for the AMF re-allocation procedure, and sending a UE security context of the UE to another Network Function (NF). The method further includes, at the target AMF, receiving a message from the RAN wherein the message includes the registration request from the UE, obtaining the UE security context of the UE from the other NF, and performing protected NAS signaling related to a registration procedure for the UE using the UE security context of the UE.Type: ApplicationFiled: August 18, 2020Publication date: September 22, 2022Inventors: Lasse OLSSON, Qian CHEN, Peter RAMLE
