A method, an apparatus, a system, and a computer program product for radio synchronous status messaging between communications units in wireless communications systems. A change of status event by one or more first communications devices is detected. A message indicative of the detected change of status event is generated. The generated message is transmitted to one or more second communications devices.

Status messaging protocol

A system, a method, and a computer program product for coordinating communication of data packets between a user device and a core network are disclosed. The system includes a first device communicatively coupled to the core network, a second device communicatively coupled to the first device. The second device receives signals from the user device. The first device and the second device share at least one functionality associated with layer 2 of a long term evolution radio access network.

Long term evolution radio access network

A data and voice communication system includes communication between a line card and an accelerator card. Voice, data, and control traffic is received from the line card and is transmitted to the accelerator card via a physical link having separate voice, data, and control logical channels. The separate voice, data, and control logical channels are represented by labeled data packets.

Communicating in voice and data communications systems

A method includes receiving information at an interface circuit and providing the information from the interface circuit to a processing circuit through a direct communications path between the interface circuit and a processing circuit, which processes the information received from the interface circuit. The method further includes providing the information from the interface circuit to the processing circuit via a crosspoint switch in response to a failure of the direct communications path, wherein the direct communication does not pass through the crosspoint switch.

Redundancy in voice and data communications systems

Card to card communications in voice and data communications systems

Apparatus is used in communicating in a data and voice communication system. The apparatus includes a line card and a crosspoint switch in communication with the line card. The apparatus also includes an accelerator card in communication with the line card and the crosspoint switch. The crosspoint switch is configured to provide a redundant communications path between the line card and the accelerator card.
