  • Patent number: 10165489
    Abstract: Embodiments comprise measures, including methods, apparatus and computer program products, for use in access network selection in a telecommunications system. The telecommunications system comprises, at least, a mobile telephony radio access network. At one or more network nodes of the mobile telephony radio access network a preference, to offload at least some data communication in the mobile telephony radio access network to a further radio access network other than the mobile telephony radio access network, is identified. In response to this identification, an indication of the identified offloading preference is caused to be transmitted, via the mobile telephony radio access network, to at least one user equipment.

  • Patent number: 9813958
    Abstract: A method, apparatus and computer program product are provided herein for enabling a D2D bearer to stay alive even in an instance in which a D2D connection is lost. In some example embodiments, a method is provided that comprises detecting a condition that indicates that a device-to-device bearer is to be terminated. The method of this embodiment may also include modifying a cellular bearer protocol data unit header, such that the cellular bearer protocol data unit header indicates that a cellular bearer service data unit is a device-to-device protocol data unit. The method of this embodiment may also include causing one or more device-to-device protocol data units to be encapsulated within one or more cellular bearer protocol data units, such that the one or more device-to-device protocol data units are transmitted via a cellular bearer.

  • Patent number: 9414421
    Abstract: Method, operation of a method, and a result of execution of computer program instructions embodied on a non-transitory computer readable memory in a mobility management entity which determines whether a source and destination address of certain Internet protocol data flow are within a specific network in an evolved packet system for evaluating and controlling potential opportunities for device to device communication among two or more proximately located user equipment. In response to determining that the target serving gateway is the source gateway, identification information of the source user equipment is sent to a target serving gateway.

  • Patent number: 9344887
    Abstract: Method, operation of a method, and a result of execution of computer program instructions embodied on a non-transitory computer readable memory in a mobility management entity which identify, evaluate and control potential opportunities for device to device communication among two or more proximately located user equipment. The method or execution of computer instructions include, determining a context of a source user equipment and a context of a target user equipment, determining if the source and target user equipment are device to device communication compatible and determining if the source and target user equipment are authenticated for employing device to device communications. An alternative embodiment includes functionality in a base station.

  • Patent number: 9344955
    Abstract: There is provided a method, including: causing, by a second node, reception of a discovery message on a radio layer directly from a first node, wherein the discovery message indicates at least the prefix of the internet protocol, IP, address corresponding to the first node; detecting whether or not there exist an application layer connection between the first node and the second node, wherein the application layer is a higher layer than the radio layer and the detection is at least partly based on the acquired prefix; and upon detecting that the application layer connection exists, indicating the existence of the application layer connection to a network element associated with the second node.

  • Publication number: 20150351054
    Abstract: In a method for limiting the maximum transmit power of devices operating in a wireless network, each device supporting one of plural sets of transmit power reduction capabilities, a first message comprising a value of a first parameter associated with a first set of capabilities and a value of a second parameter associated with a second set of capabilities, wherein the second set comprises more capabilities than the first set, is transmitted (400). A signal associated with a device's reception of the first message is received Initiate non-access-related Initiate non-access-related (410). A capability enquiry is transmitted to the device (415). Capability information comprising an indication of whether the device supports the value of the second parameter is received (420).

  • Publication number: 20150304896
    Abstract: The application relates to a mobile terminal radio stack for D2D single channel (308) and a cellular uplink single channel (324). A D2D connection is a direct connection formed between a first mobile terminal and a second mobile terminal over the cellular radio spectrum. The D2D connection is a local communication link and is generally enabled for use over short distances. Because the D2D connection could be lost quite rapidly, handover (e.g. bearer establishment) of the D2D communications to traditional cellular communications e.g. Evolved Universal Mobile Telecommunications System Terrestrial Radio Access Network (E-UTRAN)) may not occur in time to synchronize the multiple mobile terminals. As a result, multiple protocol data units between the mobile terminals may be lost.
