Patent ID: 11729737

Abstract:
Methods, apparatuses, and computer program products are provided for handling session requests for emergency services. Updated closed access group (CAG) configuration information can be provided to user equipment (UE) requesting an emergency session with a public land mobile network (PLMN), and the UE may update their CAG information or discontinue its session request. When the PLMN determines that the UE's session request to the PLMN was sent via a non-CAG cell, the PLMN may then determine if the session request is for emergency services, in which case the PLMN may decide to not clear or reject the session request, while if the PLMN determines that the session request via the non-CAG cell is for non-emergency services, then the PLMN may clear or reject the session request. When a session request is rejected by the PLMN, the UE may enter a deregistered state and conduct a search for a new PLMN.
