A real-time application-based cellular system with real-time GPS positioning to notify civilian drivers of the proximity of emergency services vehicles in sufficient time to allow appropriate response. Civilian users receive alerts and information on their personal computing devices, including, but not limited to, tablets and smart phones. No addition or special hardware is required. Only drivers in a moving vehicle with a certain proximity are directly and selectively notified. The system also is able to send other additional customized warning signals to citizens in threatening situations in a non-vehicular context.

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.

Methods and apparatuses for supporting location and emergency calls for an over-the-top (OTT) service provider are disclosed. A UE may send a request for an emergency call to an OTT service provider and may include in the request mobile network operator (MNO) data for a serving MNO for the UE. The OTT service provider may forward the emergency call request to an Internet Protocol (IP) Multimedia Subsystem (IMS). The IMS may determine routing information for the emergency call and either return the routing information to the OTT service provider to enable the OTT service provider to route the emergency call to a public safety answering point (PSAP) or may route the emergency call itself to the PSAP. The call request routed by the IMS or by the OTT service provider may include a reference identifier that may enable the PSAP to obtain a location for the UE from the IMS.

A location management device function is provided in an access network, and a base station identifies and authenticates a terminal device permitted to perform base station loopback communication on the basis of identification information on the terminal device received from the terminal device. With this configuration, provided is a communication control method and the like for the base station device that has lost connectivity to a core network, to permit only specific terminals to perform base station loopback communication.

Systems and methods are described, which prompt a UE that is receiving at least a physical layer signal from a broadcasting station to look for a new emergency alert. In embodiments, the UE renders content from the broadcasting station based on information received in transmitted physical layer frames. Included within a physical layer frame are bits, such as, ea_wake_up_bits. If the state change of the ea_wake_up_bits indicates that a new emergency message, referencing a new emergency alert, is being transmitted within the physical layer frame, the LTE locates the new emergency message within the physical layer frame and acts on the emergency message if it is applicable to the station to which the UE is tuned. If the emergency message is applicable, the UE acts on the emergency message by using information in the emergency message to locate and render the emergency alert. The emergency message may point to an EAS present on a linear TV service.

This application discloses a method and an apparatus for a terminal to access a network, a device, and a readable storage medium. The method includes: in a case that an event corresponding to a MINT function occurs in a first network, performing access control on an access request, triggered by the MINT function, for accessing a second network.

A wireless backhaul link is established between the IAB node and an IAB donor node via a first Narrow-Band Internet-of-Things (NB-IoT) carrier, in which the IAB donor node provides the IAB node with access to a wired backhaul connection that links to a core network of the wireless carrier network. One or more corresponding wireless backhaul links are further established between the IAB node and one or more additional IAB nodes via a one or more corresponding NB-IoT carriers. A wireless access link is then established between the IAB node and an NB-IoT user device or between the IAB donor node and the NB-IoT user device via a second NB-IoT carrier.

Aspects of the subject disclosure may include, for example, detecting, by a wireless communication device, a transmission, by a radio access network node, of an alert message, identifying contents of the alert message, determining that the wireless communication device is authorized to relay the contents of the alert message, generating alert information comprising the contents of the alert message, and transmitting a ProSe direct discovery message comprising the alert information. Other embodiments are disclosed.

An electronic device may transmit a communication request to a base station having an indication of a number of its receive branches and an indication of whether the communication request is designated as an urgent service fulfillment. The base station may delay a denial of the communication request until receiving the indication of whether the communication request is designated as using the urgent service fulfillment to reduce a likelihood of prematurely rejecting the communication request. The base station may also handover the communication request to a base station that supports the urgent service fulfillment. The base station may also be barred from transferring the user equipment to a frequency layer preferred by the base station when the communication request of the user equipment is designated as an urgent service fulfillment.
