Apparatuses, systems, and methods for performing efficient emergency services fallback. A cellular network element may provide emergency services fallback information to a wireless device during 3GPP 5GS cellular registration. The emergency services fallback information may include an indication of whether emergency services fallback via fallback to evolved packet core service is supported. The emergency services fallback information may also include an indication of whether emergency services fallback via fallback to circuit switched service is supported.

Disclosed are a method and an apparatus for configuring relay communication information, and an electronic device, and pertains to the field of communication technologies. The method for configuring relay communication information includes: reporting, by a terminal, a relay communication mode to a network-side device; and receiving, by the terminal, relay communication information from the network-side device, where the relay communication information includes a relay communication policy and/or authorization parameter corresponding to the relay communication mode.

A method of provisioning UE Route Selection Policy (URSP) rules received from a non-subscribed Stand-alone Non-public Network (SNPN) registered using credentials from a credentials holder (CH) is provided. After a UE register to the non-subscribed SNPN using credentials from the CH, the UE may establish a PDU session for accessing services n the SNPN. Prior to establishing the PDU session, the UE checks the corresponding URSP rules that can be used in the SNPN. If the UE is signaled with URSP rules by the registered non-subscribed. SNPN, UE should store the URSP rules and then apply those URSP rules for PDU session establishment when the UE access the services in the non-subscribed SNPN.

Embodiments herein provide methods for providing priority services to a UE by an AMF. The method includes receiving a request message from the UE, receiving, from a unified data management (UDM), subscription data of the UE, and, based on identifying that the subscription data comprises information related to a priority service and the request message does not include an establishment cause associated with the priority service, sending, to the UE, an accept message for the priority service in response to receiving the request message. The priority service comprises at least one of multimedia priority service (MPS) or mission critical service (MCX).

The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. The method includes configuring, by a User Equipment (UE) (100), a Protocol Data Unit (PDU) session type as an always-ON type or a normal PDU type. Further, the method includes sending, by the UE (100), a PDU session establishment request message including the PDU session type to be the always-ON type or the normal PDU type to a network (200) during an initial PDU session establishment procedure.
