Method for re-indexing a terminal in a communication gateway

A base station comprising means for computing communications interfaces enabling incoming calls to be received and transmitted, a radio interface enabling messages to be sent to and received from multiple terminals referenced in a memory, wherein the memory stores data referencing:

• mobile terminal identifiers associated with context identifiers;
• line identifiers enabling routing configurations to be defined when they are associated with terminals, wherein the base station comprises a configuration table for the routing of incoming and outgoing calls associating each context identifier with a predefined routing configuration, wherein the base station also comprises a function enabling a request to change a terminal identifier which has been sent by a terminal to be detected, a determination of context information comprised in the request enabling a new terminal identifier associated with a context identifier corresponding to the information extracted from the received message to be identified, and an allocation of the new terminal identifier to the terminal which made the request for change.

A terminal comprising an immutable physical address and an interface enabling a contextual element relating to a new use of the terminal to be determined, and computation means enabling a message intended to be sent to a base station transmitted by radio to be generated, wherein the message comprises:

• information identifying the previously determined contextual element and;
• a request to allocate a new terminal identifier to be associated with its immutable physical address,
• wherein, after sending the message, said terminal can receive a new terminal identifier, and change its previous terminal identifier in its memory to a new terminal identifier received from the base station.
