Abstract:
The invention relates to a mechanism for performing multicast transmission in a cellular network. In order to enable establishment of resources only in cells containing members of the multicast group and to avoid congestion on the uplink channel, a multicast service notification is transmitted to mobile stations, thereby informing members of the multicast group of an upcoming multicast session. The moment for a response to said multicast service notification is selected in the mobile stations and a presence report is sent from at least one of said mobile stations at the response moment of said at least one mobile station. The presence report or reports are received within a radio access network, and radio resources are established for multicast transmission in a cell of the cellular network when the presence report(s) received in said cell meet(s) predetermined criteria.
Abstract:
A method for increasing a user's perceived access speed to content available from a data network. The method utilizes a multicast channel and the selection of group data to be sent over that channel.
Abstract:
A compression context for a plurality of packets is established with a receiving device. Each of these packets is associated with one or more reliable multicast protocols, such as the Layered Coding Transform (LCT) protocol, the Asynchronous Layered Coding (ALC) protocol, the FLUTE protocol, the MUPPET protocol, and the NACK-Oriented Reliable Multicast (NORM) protocol. Upon establishment of the compression context, a compressed packet is generated for one of the plurality of packets and transmitted to the receiving device. The compressed packet has a reduced number of bits in its header. Upon receipt, the receiving device decompresses the compressed packet based on the compression context.
Abstract:
A method, computer program/product, system, transmitter and receiver suited for the transfer of at least one data object (50) to the receiver (101) are shown, wherein the at least one data object is associated with a respective data envelope (51) that serves for at least one of identifying, versioning and time bounding the at least one data object, the method embedding (110) the at least one data envelope and a representation of the at least one data object into a compound container object (52), and transferring (112) the compound containerobject to the receiver. The at least one data object may be a metadata object that represents a description of services and/or content that can be used by the receiver, and the compound container object is furnished with a compound container envelope (53) that serves for at least one of identifying, versioning and time bounding of the compound container object.
Abstract:
A broadband digital broadcast 1 network is described in which the cellular topology is dynamically configurable to maintain spectral efficiency. The reconfiguration of the topology occurs in response to changes in the demand for content. Thus, a single cell could be defined to cover an area in which the same content is being delivered to a substantial number of users. Conversely, a large number of cells could be defined to cover an area in which a substantial number of users are each having different content delivered to them.

Abstract:
This invention relates to a method, a computer program, a computer program product, a system, a sender, a receiver and a session description protocol for transmitting common data from one sender (902) to a plurality of receivers (901) within a transmission session, comprising communicating (802) at least one session parameter, which is related to said transmission of said common data within said transmission session, to said plurality of receivers (901) via a communication protocol; and transmitting said common data from said sender (902) to said plurality of receivers (901) within said transmission session. The invention particularly relates to broadcast/multicast transmission of common data in a wire-bound and/or wireless network, wherein a File Delivery over Unidirectional Transport FLUTE protocol is used.
Abstract:
The present invention relates to accessing data on computer networks, and more particularly to accessing such data via remote terminals. The present invention provides that unsolicited information is received via a first communications network on a communications device. Based on that information, the user can request further information via a second communications network.
