Multi-cell coordination for multimedia broadcast multicast services in a wireless communication system

The present invention is related to a method and system for multi-cell coordination for multimedia broadcast multicast services (MBMS) in a wireless communication system. An MBMS multi-cell coordination unit is provided to coordinate a plurality of evolved Node-Bs (eNodeBs) for transmission of MBMS data synchronously in multiple cells of the same single frequency network (SFN). The MBMS multi-cell coordination unit may be located in an access gateway or in an eNodeB. An MBMS multi-cell scheduling scheme may be preconfigured for the eNodeBs for synchronization. Alternatively, the eNodeBs may be synchronized dynamically.

Methods and apparatus for power efficient broadcasting and communication systems
09780959 · 2017-10-03 · ·

A method and apparatus for content multicasting and broadcasting and data unicasting in a broadband multicarrier wireless communication system. A base station is configured to transmit, and a mobile station is configured to receive, a sequence of consecutive frames. The frames comprise two types: frames containing time-frequency resources for content multicasting and broadcasting via a single frequency network, and frames containing time-frequency resources for data unicasting without the use of a single frequency network. The two types of frames are intermixed in accordance with an intermixing configuration pattern. The intermixing configuration pattern is indicated by a bit-map contained in a scheduling signal.

System and method for adding routing paths in a network
11456953 · 2022-09-27 · ·

Aspects of the present disclosure involve systems, methods, computer program products, and the like, for generating a routing table. In one implementation, BGP route broadcasts are received by a control plane of a network. The BGP route broadcasts are aggregated into a table of address summarized routes based on IP addresses included in the BGP route broadcasts. A table of attribute summarized routes is generated from the table of address summarized routes based on similarities between attributes included in the address summarized routes.

Reliable multicast/broadcast transmission scheme

In one example a computer implemented method comprises receiving, at an access point of a wireless network, a multicast/broadcast frame which identifies one or more stations associated with the access point as a recipient for the multicast/broadcast frame, and in response to a determination that at least one station of the one or more stations identified as a recipient for the multicast/broadcast frame is in an inactive state, determining a beacon slot time for a transmission of the multicast/broadcast frame from the access point, in response to a determination that at least one of the one or more stations in an inactive state will miss the beacon signal, converting the multicast/broadcast frame to a unicast frame, and holding a copy of the unicast frame to be transmitted to the at least one of the one or more stations in an inactive state that will miss the beacon signal.

Computer-based flow synchronization for efficient multicast forwarding for products and services

A method for synchronizing multicast message subflows in a switched network includes associating, with a processing device, a first destination identifier corresponding to a multicast message with a first queue that corresponds to a first output port of a switching device, associating, with a processing device, a second destination identifier corresponding to the multicast message with a second queue that corresponds to a second output port of the switching device, pausing the first queue in response to a message counter corresponding to the first queue crossing a first predetermined threshold, and unpausing the first queue in response to the message counter crossing a second predetermined threshold, wherein the message counter indicates a quantity of data that has been forwarded by the first queue but remains to be forwarded by the second queue.

Content set based deltacasting
11252210 · 2022-02-15 · ·

Methods, apparatuses, and systems are provided for improving utilization of the satellite communications system through various “deltacasting” techniques for handling content sets (e.g., feeds or websites). Embodiments operate in a client-server context, including a server optimizer, a client optimizer, and, in some embodiments, a pre-positioning client. Within this client-server context, content sets are multicast (e.g., anticipatorily pre-positioned in a local dictionary) to end users of the communications system and are handled at the content set level, according to set-level metadata and/or user preferences. In some embodiments, when locally stored information from the content sets is requested by a user, deltacasting techniques are used to generate fingerprints for use in identifying and exploit multicasting and/or other opportunities for increased utilization of links of the communications system.
