  • Publication number: 20160182312
    Abstract: Peer-to-peer service agreements can be facilitated by a third party without the terms of the service agreement being brokered by the third-party. In one example, a user sends a service request to a network node maintained by the third-party. The third-party operator identifies candidate service providers registered to provide the requested service, and sends referrals to the identified candidates. The referrals may be sent to each candidate device without filtering the candidate devices based on their real-time locations. The referrals may prompt a service agreement to be independently established between operators of the requesting device and one of the candidate devices without brokering from the third-party.

  • Patent number: 8792341
    Abstract: A method and apparatus for reporting events in a machine-to-machine environment are provided. Upon detection of an event, a determination is made whether to report the event with or without a delay. If the event is to be reported with a delay, then reporting is delayed for a period of time. If an event notification is received prior to the expiration of the delay period, then the reporting of the event may be canceled as event has already been reported by another element. If not, then another determination is made whether to report the event with or without another delay. This process continues until either the event has been reported or an event notification corresponding to the event has been received from another element.

  • Patent number: 8717960
    Abstract: A method and system for multicast and broadcast system (MCBCS) mapping and delivery to support MCBCS services is provided. Media content flows are assigned a media content identifier grouped into one or more multicast and broadcast system (MBS) services, wherein each MBS service is assigned an MBS service ID. An MBS content ID (MCID) is assigned to each MBS service. Data packets are formed that include the MBS service information (e.g., the media content flows) and classification/synchronization rules. A data path ID (DPID) is assigned to one or more MBS services dependent upon the destination of the data packets. Frames for transmission are then created and transmitted via radio frequencies. Optionally, a logical channel ID (LCID) may be assigned to each media content flow, if more than one media content flow is included within an MBS service.
