Abstract: Embodiments of the invention discloses an emergency call method and a user terminal. The method includes: obtaining a home public land mobile network (HPLMN) and an equivalent HPLMN (EHPLMN) from a SIM card of a user terminal; receiving an emergency call operation of a user; receiving, in response to the emergency call operation, a public land mobile network (PLMN) list broadcast by an access network device, which is in a multi-operator core network (MOCN), and the PLMN list includes a plurality of PLMNs that share the access network device; when the PLMN list includes the HPLMN or the EHPLMN, determining that the HPLMN or the EHPLMN is an optimal PLMN; and making an emergency call through a core network of the optimal PLMN. Thus, an emergency call center can obtain a phone number of the user terminal.

Abstract: This disclosure relates to a support device for an actuator. The support device includes a support unit adapted to be mounted to a stationary structure, an attachment unit adapted to be attached to an actuator casing and a single pivot shaft, and the attachment unit is pivotably connected to the support unit via the single pivot shaft. The support device according to the present disclosure has a simple structure and is stable in operation. The present disclosure further relates to an air intake system for an auxiliary power unit, which includes the above support device for the actuator. In addition, the present disclosure further relates to an aircraft including the air intake system for the auxiliary power unit.
