A routing selection method, apparatus, device and system and a storage medium are provided. The method includes receiving a route reassignment message sent by a serving core network device. The route reassignment message includes at least one of at least one of identification information or address information of an initial core network device; at least one of identification information or address information of the serving core network device; a context identifier assigned for a served object in at least one of the initial core network device, the access network device or the serving core network device; network slice information supported by the served object; or operator information supported by the served object.

Method, base unit and control node for misused aerial usage identification are disclosed. A method comprises: receiving location information of a mobile unit; judging whether the mobile unit is a registered aerial vehicle or an unregistered aerial vehicle; determining whether the mobile unit is in the state of flying based on the location information of the mobile unit; and identifying the mobile unit as a misused aerial vehicle in the condition that the mobile unit is determined as in the state of flying and is judged as the unregistered aerial vehicle.

Embodiments of this application disclose a network access method. The method may include: receiving, by a data management network element, a request message from an access and mobility management function network element, where the request message includes identification information of user equipment and identification information of a residential gateway connected to the user equipment; determining, by the data management network element, subscription data of the residential gateway based on the identification information of the residential gateway; determining, by the data management network element, a subscription type of the user equipment based on the subscription data of the residential gateway and the identification information of the user equipment; and sending, by the data management network element, indication information of the subscription type to the access and mobility management function network element, where the subscription type indicates a subscriber or a non-subscriber of the residential gateway.

An apparatus is provided. The apparatus includes a memory storing one or more instructions and a processor. The processor execute the one or more instructions to: receive update information from an external apparatus, the update information corresponding to a network communication; obtain a Subscription Concealed Identifier (SUCI) based on the update information; and transmit the SUCI to the external apparatus.

Provided are a method and device for efficient public land mobile network (PLMN) selection upon authentication failure for each network slice in a roaming network. A user equipment (UE) receives a registration rejection message from an access and mobility management function (AMF) of a first PLMN. The registration rejection message includes rejected network slice selection assistance information (NSSAI) including first single NSSAI (S-NSSAI) and cause value #62 for the rejected NSSAI. The UE: generates second requested NSSAI including second S-NSSAI on the basis that i) the UE does not have allowed NSSAI and configured NSSAI, and ii) default configured NSSAI includes the second S-NSSAI that is not included in the rejected NSSAI and corresponds to a network slice of which the UE requests registration; and transmits a second registration request message including the second requested NSSAI to the AMF of the first PLMN.

A method supporting enhanced network identity (NID) provisioning under User Equipment (UE) mobility scenarios between different types of networks is proposed. When a UE registers to an SNPN, the UE is assigned with a 5G-GUTI by the SNPN. The SNPN is identified by an SNPN ID==PLMN ID+NID. When the UE moves from the SNPN to another target network having a target AMF, the UE triggers a mobility registration update procedure and provides the 5G-GUTI along with NID information in a Registration Request to the target AMF. The target AMF can use the NID information along with the 5G-GUTI to find a source AMF for deriving UE context for the subsequent operations during the mobility registration update procedure. Providing NID information along with 5G-GUTI can assist the target AMF to find the source AMF efficiently, preventing a potential registration procedure failure.

Authenticity detection method and system have been disclosed herein for detecting an authenticity of a ride in a ride hailing environment. A set of geohashes is determined based on historical location data and a set of cell tower hashes is determined based on historical telecom data. A cellular network data corpus is generated based on the set of geohashes and the set of cell tower hashes. First location data and first telecom data are received from a driver device of a driver. A first geohash is determined based on the first location data and a first cell tower hash is determined based on the first telecom data. The authenticity of the ride is detected based on at least the cellular network data corpus, the first geohash, and the first cell tower hash.
