Embodiment Construction
[0030] Figure 1 shows a telecommunications system according to the present invention, the telecommunications system comprising: a first access system 1 according to the present invention, the access system having a server 14 according to the present invention and having conversion components 11, 12 according to the present invention; And possibly also a second access system 2 according to the invention. The first access system 1 is connected to the first terminals 3, 4, and 5 and is connected to the second access system 2, and the second access system is also connected to the second terminals 6, 7, 8 through the base station. The first terminals 3, 4, and 5 are fixed terminals, but may also be cordless or mobile terminals that communicate with the access system 1 through a base station or the like. The second terminals 6, 7, 8 are mobile terminals, but can also be fixed or cordless terminals. There may be other units (such as local switches, routers, bridges, etc.) between the (fi...

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 (1) is provided with a generating section (21) 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 (22) replaces addresses of a second kind by corresponding addresses of a first kind, and an adding section (23) 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 (24,25) activate translating sections (11,12), which translating sections (11,12) translate addresses of one kind into addresses of an other kind, in packets.
Description
Technical field [0001] The present invention relates to a telecommunications system. The telecommunications system includes a first access system that performs first communication with a first terminal and a second access system that is connected to the first access system and performs second communication with a second terminal. A system, wherein the first communication includes a first packet containing a first type of address, and the second communication includes a first packet containing a first type of address or a second packet containing a second type of address. [0002] The present invention also relates to an access system used in a telecommunications system. The telecommunications system includes a first access system for performing first communication with a first terminal and a second terminal connected to the first access system for performing first communication. The second access system of the second communication, wherein the first communication includes a first ...
