Electrical device designed to operate in an alternative operating mode in which the electrical device accesses a mobile telephony network (2), the electrical device having a central processing component (3) designed to manage the operation of the electrical device, a reception device (15) for receiving a SIM card (16), a presence detector (17) for detecting the presence of the SIM card, and a communication module (6) dedicated to communications with the mobile telephony network and linked to the reception device (15), the electrical device being characterized in that the central processing component (3) comprises a detection input (22) linked to the presence detector (17), such that the central processing component (3) is designed to determine whether or not the SIM card (16) is positioned in the reception device (15) without activating the communication module (6).

Methods and apparatus are provided for EPS fallback status report by the modem to the upper layers. In one embodiment, the mobile terminal (MT) initiates a 5G voice call, detects an EPSFB triggered by the wireless network, identifies one or more EPSFB status and sends one or more EPSFB status indicators to at least one upper layer based on the identified one or more EPSFB status. In one embodiment, the EPS fall back is a redirection procedure. In another embodiment, the EPS fallback is a handover procedure. In yet another embodiment, the one or more EPSFB status indictors comprising a redirection to EPS started indicator, a handover to EPS started indicator, a redirection to EPS failed indicator, a handover to EPS failed indicator, a redirection to EPS success indicator, and a handover to EPS success indicator. In one embodiment, the MT sends EPSFB status indicators using AT command.

A method and apparatus may include receiving, by a user equipment from a source cell, a first configuration configured for conditional handover and dual active protocol stack handover with a reduced target cell configuration, and a second configuration configured for conditional handover only. The method may further include determining, by the user equipment, the availability of at least one radio link associated with the source cell. The method may further include performing, by the user equipment, a conditional handover procedure according to at least one of the received configurations based upon the determination.

An application acceleration method includes identifying a data packet to be transmitted by an application running on a mobile terminal as a data packet to be accelerated to an application server, and determining network communication qualities of a first network transmission path to an access node via a wireless LAN communication network and a second network transmission path to the access node via a mobile network. The method further includes selecting a network transmission path based on network communication quality from the first network transmission path and the second network transmission path, and transmitting the data packet to the access node via the selected network transmission path such that the access node transmits the data packet to the application server through the network acceleration channel. Apparatus and non-transitory computer-readable storage medium counterpart embodiments are also contemplated.

A method for cell management, a terminal, and a network-side device are provided. The method, applied to a terminal, includes: receiving configuration information sent by a network-side device, where the configuration information includes an evaluation period and a trigger condition for triggering the terminal to perform a cell management operation; and if the duration of satisfying the trigger condition is less than the evaluation period, skipping performing the cell management operation; and/or if the duration of satisfying the trigger condition is greater than or equal to the evaluation period, performing the cell management operation.

A base station that includes a memory for storing computer readable code and a processor operatively coupled to the memory is provided herein. The processor is configured to transmit, to a terminal apparatus, information associated with communication delays predicted for communication between the base station and the terminal apparatus. The terminal apparatus acquires the information associated with the communication delays from the base station.

Methods and apparatus, including computer program products, are provided for handovers including fallbacks. In some example embodiments, there is provided an apparatus comprising at least one processor and at least one memory including program code which when executed causes the apparatus to at least: receive, during creation or modification of a bearer, a message including a handover threshold based at least in part on a type of codec for the bearer; receive, from a user equipment, a measurement report providing an indication of a condition of the bearer and/or perform a measurement, by the base station, providing the indication of the condition of the bearer; determine, based at least on the handover threshold, whether to initiate a handover. Related apparatus, systems, methods, and articles are also described.
