            3.1.3   multi-connection [ITU-T Y.2251]: The functionality which provides capability to the user equipment
            (UE) and network to maintain more than one access network connection simultaneously.

            3.2     Terms defined in this Recommendation

            This Recommendation defines the following terms:
            3.2.1   mobile device: A device capable of connecting to a mobile access network (e.g., 2G, 3G, 4G, Wi-Fi)
            including the feature phone, smart phone, tablet, laptop, camera, vehicle, etc.
            3.2.2   network  discovery:  In  a  multi-connection  environment,  network  discovery  is  a  mechanism  for
            mobile devices to discover all available network accesses and optionally display their names on the mobile
            devices.

            3.2.3   network selection: In a multi-connection environment, network selection is a mechanism for the
            network and/or mobile device to select the preferred network access based on a set of selection criteria (e.g.,
            service type, bandwidth).

            5       Conventions
            In this Recommendation:
            The keywords "is required to" indicate a requirement which must be strictly followed and from which no
            deviation is permitted if conformance to this document is to be claimed.
            The keywords "is prohibited from" indicate a requirement which must be strictly followed and from which
            no deviation is permitted if conformance to this document is to be claimed.
            The keywords "is recommended" indicate a requirement which is recommended but which is not absolutely
            required. Thus this requirement need not be present to claim conformance.
