Techniques are described for supporting satellite wireless access for a user equipment (UE) using fixed tracking areas (TAs). TA identities (TAIs) are broadcast in a satellite radio cell by a base station indicating which TAs are covered by the radio cell. A UE can access a radio cell if at least one broadcast TAI is not forbidden for the UE. A base station provides the TAIs broadcast in a radio cell and a TAI for a TA in which a UE is located to a core network node to support access by the UE. The core network node uses the broadcast TAIs to decide whether UE access is allowed and uses the broadcast TAIs and the TAI to assign a UE registration area. The UE may transfer all the broadcast TAIs to a forbidden TAI list if UE access is rejected by the core network node.

A method includes responsive to a device sensing a phone being adjacent to the device, triggering the device and the phone in a preliminary communication mode; periodically broadcasting by the device in the preliminary communication mode a broadcast message (P2) with a unique identification; detecting a strength of the broadcast message (P2) by the phone; responsive to detecting the strength of the broadcast message (P2) greater than a first threshold (T1), establishing a restricted wireless connection between the phone and the device; transmitting packages between the device and the phone via the restricted wireless connection; detecting strengths of the packages; and responsive to detecting strengths of the packages respectively greater than the first threshold (T1) and a second threshold (T2), establishing a complete wireless communication between the device and the phone so as to connect the device to the network via the phone.

Disclosed are a system and method of regulating mobile device communications while operating a motor vehicle. One example method may include determining a speed event indicating that a speed of the motor vehicle has performed at least one of exceeded a first threshold above which mobile device usage restriction policies are invoked and fallen below a second threshold allowing the mobile device restriction policies to be removed. The first threshold may be equal to or greater than the second threshold. As a result of obtaining the speed event, the method may also provide transmitting the speed event to a remote edge gateway server located remotely from the motor vehicle, which stores the speed event for reference purposes when determining a policy for routing a particular mobile device call, text message and/or mobile data session.

A method and system for protocol data unit (PDU) session release due to violation of time or location information element constraints is provided. Operations may be part of optimizing operation of a user equipment (UE) in a wireless communications network. A policy control function (PCF) determines whether there is a violation of at least one of location information and time information associated with a background data transfer. Upon detecting such a violation, the PCF requests a session management function (SMF) to release a PDU session associated with the background data transfer. The SMF responds by releasing the PDU session.

The invention provides a method performed by a home public land mobile network, PLMN, of controlling access of a user equipment, UE, device to a non-home PLMN when the UE device has an access to a non-trusted network and thereby a connection with the home PLMN via an interworking function entity, the method comprising in the event of the UE device requesting an attachment to the non-home PLMN, making in the home PLMN a decision as to whether control of the UE device should be handed over to the non-home PLMN; and communicating the decision to the non-home PLMN.

A system for reducing traffic accidents caused by distraction from a mobile telecom device. The system detects when the device is near a driver's seat of a moving vehicle. While the system is carrying a voice call between a remote voice device and the mobile device, the system modifies voice signal transmission between the devices by periodically playing a beep or other signal to remind the parties that one of them is driving and suspends voice signal transmission from the remote device to the mobile device when the system detects that circumstances affecting level of attention required for driving merit the driver paying greater attention.
