Title: Telecommunications system which includes two networks
Inventor: HANCOCK ROBERT EDWARD
IPC: H04L29/12
Filed: 2004-09-08
Abstract: The present invention relates to a telecommunications system, in particular to a telecommunications system which includes a mobile network having a plurality of portable communication devices, and, a fixed network which includes a signaling agent, a plurality of directory agents, and a plurality of spaced apart attachment points to which the mobile network can attach. In use, each directory agent stores a routing table for routing data to a respective mobile communication device associated with that directory agent. When the point of attachment of the mobile network changes, the mobile network sends a change-of-address message to the signaling agent. In response, the signaling agent is configured to forward the change of address to each directory agent, so that each can update its routing table to take into account the changed point of attachment of the mobile network. Because a signaling agent is provided, each potable device need not itself notify its directory agent when the mobile network moves, and the amount of signaling between the mobile network and the fixed network when the mobile network moves is reduced.

Abstract: La présente invention concerne un procédé d'examen d'une région réservoir dans une formation souterraine par relevé sismique périodique. La formation souterraine considérée comprend une autre région de formation adjacente de la région réservoir. Le procédé comporte plusieurs opérations. On commence par obtenir des données de relevé sismique périodique comportant des données sismiques concernant la formation souterraine en un premier instant et en un instant ultérieur. On traite les données sismiques de façon à obtenir une représentation sismique de modification affectant un paramètre sismique, lié à la contrainte, défini de l'autre région de la formation. Une interprétation de la représentation sismique du changement affectant le paramètre sismique dans l'autre région de formation permet alors de faire apparaître une indication concernant un changement de la distribution de la contrainte dans l'autre région de la formation. La dernière opération consiste en une déduction d'une propriété de la région réservoir à partir de la modification de la distribution des contraintes dans l'autre région de la formation.
