A first network node of a first frequency layer, acquires (201) information on services that are offered by a second network node at a second, different frequency layer. The second network node is within the coverage area of the first network node. The first network node broadcasts (202) a service advertisement message to at least one terminal device (UE) for advertising the services offered by the second network node at the second frequency layer.

Disclosed are various embodiments for on-demand application-driven network slicing. In one embodiment, it is determined that an application implemented in a particular computing device has an increased quality-of-service requirement in order to send or receive data via a communications network. The increased quality-of-service requirement is greater than an existing quality-of-service provided to the application by the communications network. The application sends a request that causes capacity in a network slice having the increased quality-of-service requirement in the communications network to be allocated for the application. The data is transmitted to or from the application using the network slice.

A compatibility system for determining a technical compatibility of one or more electronic devices and one or more mobile network operators is disclosed. The compatibility system obtains data from a plurality of data sources and integrate the data to generate a platform that determines ability of at least one of: the electronic devices and the mobile network operators for a communication between each other. The compatibility system determines device attributes and network attributes by integrating the compatibility system with data related to electronic devices and mobile network operators respectively. The compatibility system evaluates radio bands supported by the electronic devices and mobile network operators and identifies potential carriers of the mobile network operators, and a plurality of known potential countries globally, which are compatible with the radio bands of the one or more electronic devices in order to determine the compatibility of the electronic devices and the mobile network operators.

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 user equipment transmits user equipment information, associated with a communication of the user equipment, to permit a base station to select a first bandwidth part, a second bandwidth part, or a third bandwidth part. The user equipment is configured to communicate by the first bandwidth part, the second bandwidth part, and the third bandwidth part. The user equipment receives, from the base station, an instruction to monitor the first bandwidth part, the second bandwidth part, or the third bandwidth part. The instruction is selected based on the user equipment information. The user equipment monitors, based on the instruction, the first bandwidth part, the second bandwidth part, or the third bandwidth part.

A method and apparatus may receive policy information from a network. The policy information indicates at least one preferred radio-access-technology for a service. The method may also include entering a coverage area of the at least one preferred radio-access-technology. The method may also include detecting that the service corresponding to the at least one preferred radio-access-technology is offered in the coverage area. The method may also include initiating a request for setup of the detected service.
