Telecommunication/access system for dealing with different address lengths |
摘要 |
Telecommunication systems should be able to handle different protocols. Thereto, with a first protocol being Internet Protocol v6 using 128-bit addresses of a first kind and with a second protocol being Internet Protocol v4 using 32-bit addresses of a second kind, an access system is provided with a generating section for, in response to an address of one kind, generating a corresponding address of an other kind for a terminal-to-terminal communication and independently of which terminal has initiated said terminal-to-terminal communication. For a set-up phase, a replacing section replaces addresses of a second kind by corresponding addresses of a first kind, and an adding section adds, in addition to addresses of a first kind, corresponding addresses of a second kind, in set-up messages. For a communication phase, activating sections activate translating sections, which translating sections translate addresses of one kind into addresses of an other kind, in packets. |

1. A method for setting up communication between a first terminal using a first protocol and a second terminal using a third protocol, said first protocol using packets having sizes smaller than the packets of said third protocol, the method comprising:
if receiving a communication request from said first terminal requesting communication with said second terminal, said request comprising a first protocol first terminal address and a second protocol second terminal address, providing said first protocol first terminal address to a generating section, to request a corresponding third protocol first terminal address, providing said third protocol first terminal address, to said second terminal, providing a third protocol second terminal address to said generating section to request a corresponding first protocol second terminal address, and providing said first protocol second terminal address to said first terminal; and if receiving a communication request from said second terminal requesting communication with said first terminal, said request comprising a third protocol second terminal address and a second protocol first terminal address, providing said third protocol second terminal address to said generating section, to request a corresponding first protocol second terminal address, providing said third protocol second terminal address and said first protocol second terminal address to an access server coupled to said first terminal, receiving a message from said first terminal comprising said first protocol first terminal address, providing said first protocol first terminal address to said generating section, to request a corresponding third protocol first terminal address, and providing said corresponding third protocol first terminal address to said second terminal.
