Method for attaching a user terminal to a packet network

摘要

A method for attaching a user terminal to a packet network via a meshed radiocommunications network infrastructure includes selecting a host packet network dedicated to at least a category of users to which a user terminal belongs based on a second user identification code of the meshed network and/or access information pertaining to rights for attachment of user terminals to at least one packet network. The method finds an application in all types of infrastructure of meshed radiocommunications networks and finds a particularly interesting application in the case of PMR type professional radiocommunications networks.

1. A method for attaching a user terminal to a host packet data network via a meshed radiocommunications network infrastructure, said meshed radiocommunications network infrastructure comprising:
a plurality of base stations, each base station being capable of accomplishing radio transmission and reception with at least one user terminal located in a cell attached to said base station; a plurality of entities for authenticating and monitoring user terminals; a plurality of entities for attachment to packet data networks; a plurality of distribution gateways, each distribution gateway being capable of connecting at least one of the base stations to at least one of the plurality of entities for attachment; a data base comprising access information pertaining to rights for attachment of user terminals to at least one of the packet data networks; wherein said method comprises: receiving a request of attachment of said user terminal to a packet data network, the request from said user terminal being received by a base station attached to a cell in which the user terminal is located, the request comprising a unique identification code comprising a meshed network identifier code and a user identification code, checking the access rights of said user terminal to said meshed radiocommunications network infrastructure by checking if the received meshed network identifier code is identical to a meshed network identifier code memorized in said base station, authenticating the user of the user terminal by comparing the received unique identification code to a unique identification code comprised in the data base; selecting said host packet data network dedicated to at least one category of users to which the user terminal belongs according to the received user identification code; selecting a first entity for attachment among the plurality of entities for attachment attached to said host packet data network based on data pertaining to a topology of the meshed radiocommunications network infrastructure representing interconnections in said meshed radiocommunications network infrastructure, establishing an access channel between the selected first entity for attachment and a distribution gateway connected to said base station, according to said data pertaining to the topology of the meshed network infrastructure.
