  • Patent number: 9654900
    Abstract: Systems, methods, and instrumentalities may implement service-based discovery in a network, such as a 3GPP or 3GPP2 network. A Discovery Server may be used to query and find services offered by the network or by entities that interface with the network. Situational context information or policy information, or both, may be communicated to the discovery server so that the Discovery Server can provide context-aware and policy-based discovery services. The Discovery Server may be used to control which of the entities that interface with the network can discover one another. The Discovery Server may support queries based on, for example, the type of MTC entity, the type of services hosted on the entity, the availability times of the entity, types of protocols supported, levels of Quality of Service (QoS) supported, and MTC-IWF services.

  • Patent number: 9638783
    Abstract: Methods, systems, and devices are described for peer-to-peer or device-to-device location services. Mobile devices with a known location (referred to as landmarks) may broadcast their location information and/or a reference signal for other mobile devices (referred to as targets). Landmarks may determine their location through GPS or other location determining means. Targets may have limited or no connection to location determining services, and they may use broadcast information from landmarks, without a request, to determine the targets' location. The targets may determine absolute and/or relative locations. Once a target device determines its location it may assume a role of a landmark to provide broadcast location information to other devices.

    Abstract: The present invention is to provide a method for allocating multi-UEs' Sounding Reference Signal (SRS) uplink resources, and an eNB for allocating multi-UEs' SRS uplink resources with the method. The method may automatically and dynamically allocate multi-UEs' SRS resource in both the time domain resource and the frequency domain resource in accordance with system capacity attribute value and configured SRS transmission period. When multi-UEs' SRS are positioned in the same time domain resource and same frequency domain resource, it is also possible to further divide the multi-UEs' SRS automatically by a method of configuring cyclic shift. According to the method of the present invention, the eNB may allocate SRS resources for multi-UEs more flexibly and effectively, which reduces disturbance to multi-UEs' SRS, improves the decoding performance of physical layer, and thus improves the stability of a system.

  • Patent number: 9491290
    Abstract: A method is performed by a message-originating communication device. The method includes inputting, by the device's user interface, a request to deliver a message to a first address. The device accesses, in response to receiving the request, a memory to determine a second address that is associated in the memory with the first address. The device then transmits the message to the first address and transmits the message to the second address.

  • Patent number: 9474078
    Abstract: Embodiments herein include a method in a server for scheduling of an information transmission from an information providing device to a subscriber equipment in a communication system. The method comprises determining a moment in time at which the subscriber equipment desires information. Also, an estimation of the communication intensity in the communication system at the determined moment in time is obtained. If the estimated communication intensity exceeds a certain threshold value, an appropriate period in time for the information providing device to send desired information to the subscriber equipment is calculated, based on the communication intensity in the communication system. Furthermore, a trigger signal is sent to the information providing device, requesting the information providing device at what moment in time to provide information to the subscriber equipment. A method in an information providing device is also disclosed.

  • Patent number: 9467827
    Abstract: Communication is facilitated between cellular and digital mobile radio devices. In one aspect, a digital mobile radio messaging gateway is deployed within a cellular network that allows cellular devices to send and/or receive data (e.g., text messages, media content, voice calls) to digital mobile radio devices. Moreover, the digital mobile radio messaging gateway provides transparent messaging access from devices to digital mobile radio switches and/or gateways essentially making the cellular network an extension of the digital mobile radio network. As an example, the digital mobile radio messaging gateway converts data received from the digital mobile radio network to a message that conforms to a protocol supported by the cellular network. Similarly, the digital mobile radio messaging gateway converts data received from the cellular network to a message that conforms to a protocol supported by the digital mobile radio network.

  • Patent number: 9450710
    Abstract: A method and apparatus for compressing resources used for transmitting acknowledgment signals from User Equipments (UEs). An acknowledgment signal is in response to detections from a UE of one or more Physical Downlink Control CHannels (PDCCHs) in respective one or more Transmission Time Interval (TTIs) within M TTIs. Each PDCCH is transmitted over Control Channel Elements (CCEs). Resources account for both CCEs in a same TTI and for TTIs within the M TTIs. A Hybrid Automatic Repeat reQuest (HARQ) Acknowledgment Resource Offset (HRO) field in a Downlink Control Information (DCI) format is used to compress resources in both CCE and TTI domains. For the first TTI of the M TTIs, all HRO values compress resources in the CCE domain while for all remaining TTIs, half HRO values compress resources in the CCE domain and half HRO values compress resources in the TTI domain.
