The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate, and provides an apparatus and a method for transmitting service provisioning information to a UE when the UE is in a reachable state. An operation method of a policy control function (PCF) entity includes: receiving a data management message including a service parameter generated by an application function (AF) entity from a network exposure function (NEF) entity; transmitting an N1N2 message indicating to transmit the service parameter to a user equipment (UE) to an access and mobility management function (AMF) entity; receiving, from the AMF entity, a transfer result message indicating whether the service parameter has been transmitted to the UE; and transmitting the transfer result message to the AF entity.

Exemplary embodiments include a method, performed by a session management function (V-SMF) of a visited public land mobile network (VPLMN), for establishing a user-requested PDU session to be routed through the user's home PLMN (HPLMN). Such embodiments include receiving, from an access management function (AMF) in the HPLMN, a first request to establish a home-routed PDU session, wherein the first request identifies an SMF (H-SMF) in the HPLMN. Such embodiments also include sending, to the H-SMF, a second request to create the home-routed PDU session. The second request can include an identifier of a resource in the V-SMF associated with the PDU session; and one or more indicators of whether the V-SMF supports respective one or more features related to receiving, from the H-SMF, an identifier of a resource in the H-SMF that is associated with the PDU session. Embodiments also include complementary methods performed by the H-SMF.

A first access and mobility management function (AMF) in a network receives, from user equipment (UE), a registration request listing a first network slice and a second network slice. Upon determining that the first AMF supports the first, but not the second, network slice, the first AMF causes selection of (i) the first AMF as a session and mobility management (SM)-AMF to perform mobility management, and first session management signaling for the first network slice; and (ii) a second AMF as a session management only (SO)-AMF to perform only second session management signaling for the second network slice. The first AMF, acting as SM-AMF, performs the first session management signaling for a first data session on the first network slice, while the second AMF, acting as SO-AMF, performs only the second session management signaling for a second data session on the second network slice.

Systems and methods for reporting API capability change according to an API filter are provided. According to one aspect, a method for reporting API capability change according to an API filter comprises receiving a request to be notified of an API capability change related to an identified wireless device, the request identifying a set of one or more APIs to be monitored; receiving a notification that the identified wireless device has changed from a first type of core network to a second type of core network; determining an API capability change from the first type of core network to the second type of core network for the identified set of one or more APIs to be monitored; and reporting the API capability change for the identified set of one or more APIs to be monitored and not reporting the API capability change for APIs not in the identified set.

Tracking devices can be associated with safe zones, smart zones, and high risk zones. Safe zones correspond to regions where a likelihood that a tracking device is lost within the safe zone is lower than outside the safe zone. High risk zones correspond to regions where a likelihood that a tracking device is lost within the high risk zone is higher than outside the high risk zone. Smart zones correspond to an expected tracking device, mobile device, or user behavior. Home areas are geographic regions in which a user resides, and travel areas are geographic regions in which a user does not reside. A tracking device can be configured to operate in a mode selected based on a presence of the tracking device within a safe zone, a smart zone, a high risk zone, a home area, or a travel area.

Embodiments herein disclose methods for handling operation of a UE during a disaster situation by the UE. The method includes initiating a wait timer upon selecting a forbidden public land mobile network (FPLMN) to receive a disaster roaming service. Further, the method includes determining whether at least one of: a MS is registered via a non-3GPP access or 3GPP access to another allowable PLMN, the FPLMN has stopped broadcasting a disaster related indication, and the FPLMN has stopped broadcasting the PLMN with the disaster condition. Further, the method includes stopping the wait timer and performing a PLMN selection procedure based on the determination. The provided method optimizes the operations in disaster situations.

Aspects of the present disclosure include methods, apparatuses, and computer readable media for establishing a first communication link with a base station (BS), establishing a second communication link with a second UE, generating a timing advance group (TAG) capability report comprising a plurality of link-specific TAG numbers supported by the UE, wherein a first TAG number of the plurality of link-specific TAG numbers is associated with the first communication link and a second TAG number of the plurality of link-specific TAG numbers is associated with the second communication link to the BS, and transmitting the TAG capability report to the BS.

A wireless communication network serves a User Equipment (UE) and exports UE capability data. A UE Capability Management Function (UCMF) receives the UE capability data and transfers the UE capability data to a Network Exposure Function (NEF). The NEF transfers the UE capability data to another wireless communication network. The UCMF receives additional UE capability data. The NEF receives a UE capability request for the UE from the other wireless communication network. In response, the NEF transfers the UE capability request for the UE to the UCMF. The UCMF transfers additional UE capability data to the NEF. The NEF transfers the additional UE capability data to the other wireless communication network.
