The RAN transmits the converted multicast message with the second format (e.g., a data over signaling (DOS) message) on a control channel to at least one of the plurality of access terminals. The access terminals receiving the converted multicast message interpret the message as a multicast message.

The generated data stream may comprise one or more sub-streams. The scheduling information may be checked or validated to assure consistency and accuracy. Client systems may simultaneously receive data, including real-time data, from multiple sources.

METHOD AND DEVICE FOR IMPLEMENTING A TRANSACTION CONCEPT IN OPC UA BY MEANS OF A TIMEOUT MECHANISM

In the OPC UA request header, there exists the field “TimeoutHint”, by means of which the client can indicate the point in time from which the client is no longer interested in the result of an operation. When this time has expired, the server sends a response that the execution of the operation has been terminated. According to the invention, the semantics of the field “TimeoutHint” in the OPC UA request header are used differently. The meaning of the “TimeoutHint” is changed in such a way that the “TimeoutHint” no longer indicates the latest point in time at which an operation should be executed, but rather the earliest point in time. 110.-.

Location specific event broadcasting

Applications in a broadcast environment distribute events in real-time to a large number of receivers within specified geographic locations while efficiently sharing bandwidth resources with other applications using the same broadcast network. Applications need not be aware of the other applications sharing the resources, nor of the methods, protocols, and other mechanisms used to actually broadcast the data over the broadcast medium. Server-side applications that serve data, send notifications, or distribute events to specific locations within the network use a broadcast location manager. Client applications that receive such data, notifications, or events use a client location filter to obtain events that are relevant based on the location of the device. The broadcast location manager and client location filter work together to reliably and efficiently transmit data, notifications, and events to specific locations over the broadcast network for all applications involved.

Method and apparatus for multiple media digital communication system

The present invention is embodied in a digital communication system where multiple media data sources are time multiplexed into a packetized data stream, each packet having an assigned priority and the packetized data stream transmitted in substantially the order of assigned priority. At both the transmit side, and the receive side, audio packets are given priority processing over video packets, which in turn have priority over text/graphics data packets. Continuous real time audio playback is maintained at the receiver by delaying the playback of received audio in a first in/first out (FIFO) buffer providing a delay at least equal to the predicted average packet delay for the communication system. Optionally, the average system delay is continuously monitored, and the audio playback delay time is adjusted accordingly. Audio playback is slowed or accelerated in order to shrink or grow the difference in time between the sender and receiver. In another aspect of the invention, a conference ...

Switch fabric with memory management unit for improved flow control

A method for controlling a flow of packet data in a memory management unit of a network switch fabric is disclosed. A first portion of a data packet is received at a port on an ingress bus ring of the network switch fabric. A class of service for the data packet is determined based on the first portion and the portion is stored in a packer RAM of the port based on the class of service. Subsequent portions of the data packet are stored in the packer RAM. Once the predetermined number of portions have been received, the predetermined number of portions is sent to a packet pool RAM. A reference pointer to a first predetermined number of portions is sent to a transaction queue once an end of packet is detected and an egress scheduler detects a presence of a ready packet in the transaction queue and notifies an unpacker of the ready packet.

Message transmission

A method of transmitting a message to user equipment within a telecommunications network, a controller operable to transmit a message to user equipment within a telecommunications network, a base station and a computer program product are disclosed. The method comprises the steps of: receiving a message having message content to be transmitted to user equipment within a predefined geographical area of the telecommunications network; identifying at least one multicast IP address designated as being associated with base stations providing telecommunications coverage with user equipment within the predefined geographical area; and transmitting the message content within at least one multicast message, each multicast message using a corresponding one of the at least one multicast IP address, over an IP network to base stations providing telecommunications coverage within the predetermined geographical area for onward transmission to user equipment. In this way, each base station identified by the multicast IP address will simultaneously receive the message, rather than each individual base station needing to have its own dedicated message sent to each base station sequentially. This not only significantly speeds the time taken for identified base stations to receive the message, it also reduces the amount of traffic required since the message is transmitted in a multicast manner. Furthermore, only those base stations which are associated with the multicast IP address will act on the message, all other base stations may ignore it. This helps to ensure that the message is only relayed to user equipment in a particular geographical region, rather than being delivered to all user equipment supported by all base stations associated with a particular controller.

Deletion of blocks in a blockchain

In a mechanism for deleting blocks from a blockchain, a retention period (T), a minimum number of blocks (L), and a hash of the oldest block are defined. A participant node creates the new block including a block header. The participant node determines whether a timestamp in an oldest block in the blockchain is older than a current time plus T, and whether a current number of blocks in the blockchain is greater than or equal to L. When both are true, the participant node deletes an oldest block in the blockchain. The participant node adds a hash of an oldest remaining block and an original number of blocks of the blockchain to the block header of the new block. The participant node broadcasts a message announcing the new block to remaining participant nodes of the plurality of participant nodes.
