Method and apparatuses for establishing a link between two devices

摘要

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.

1. A method for establishing a link in an Open Systems Interconnection (OSI) layer 2 or 3 via which at least one data stream is intended to be transmitted, a first router and a second router respectively forming a first and a second end of the link, a first base station being connected to the first router, and a second base station being connected to the second router, wherein the first base station has selected the second base station from amongst a plurality of base stations in anticipation of and before a handover procedure, the method being implemented by the first router and comprising:
in anticipation of and before the handover procedure, extracting an identifier of the first base station and an identifier of the second base station comprised in a message transmitted by the first base station; in anticipation of and before the handover procedure, creating a first point of attachment in the first router, the first point of attachment intended to form the first end of the link, wherein an identifier of the first point of attachment comprises the identifier of the first base station; in anticipation of and before the handover procedure, determining the identifier of the second base station as an identifier of a second point of attachment in the second router, the second point of attachment intended to form the second end of the link; and in anticipation of and before the handover procedure, sending a request for establishing the link to the second router, the request for establishing the link comprising the identifier of the first point of attachment and the identifier of the second point of attachment.
