The invention concerns a system for multipoint-to-multipoint radio data transport, comprising a device for switching samples of digitised radio data called samples, transmitted by a device for the digital processing of antenna signals called antenna device (RU, RU), via a first data link (DL, DL), to a plurality of recipient antenna controller devices (DU, DU) identified by a respective plurality of controller identifiers, the switching device (DD) comprising the following modules: interception of first data frames (T, T) from the antenna device and intended for the plurality of controller devices, the first frames comprising the samples, demultiplexing the samples from the intercepted first data frames, extracting the controller identifiers from the intercepted first data frames, grouping together the demultiplexed samples by controller identifier, multiplexing the samples by group in second data frames (T, T), a second data frame being associated with a controller identifier, transmitting the second data frames via a plurality of second data links (DL, DL) associated respectively with the plurality of recipient antenna controller devices.

Multipoint-to-multipoint radio data transport

The invention relates to a method for establishing a link through which at least one data stream is to be transmitted. A first communication facility and a second communication facility form a first and second end of the link, respectively. A first base station is connected to the first communication facility, and a second base station is connected to the second communication facility, the first base station having preselected the second base station from among a plurality of base stations. The method includes the following steps, implemented by the first communication facility: extracting an identifier of the first base station and an identifier of the second base station, said identifiers being included in a message transmitted by the first base station; and establishing the link between the first communication facility and the second communication facility from the extracted identifier of the first base station and the extracted identifier of the second base station.

Method and apparatuses for establishing a link between two devices

A method for communicating between first termination equipment and at least one second and one third termination equipment through respective first and second pseudo links in a packet-switching network. The method includes the following steps performed by the first termination equipment: intercepting a data frame sent by first customer equipment, connected to the second termination equipment, to second customer equipment, the data frame including identifiers of the first customer equipment and the second customer equipment; determining a parameter for identifying the second termination equipment, based on the identifier of the first customer equipment; and determining a parameter for identifying the third termination equipment, based on the identifier of the second customer equipment; and transmitting, to the second termination equipment, of a request to establish a third pseudo-link between the second termination equipment and the third termination equipment through which the data sent by the first customer equipment are transmitted.
