Embodiment Construction

[0026] Figure 1 shows a system in which the method of the present invention can be implemented. The system comprises a core network 10 , a first access network referred to herein as a private radio access network 11 , a second access network referred to herein as a remote access network 12 , and a mobile terminal 13 .

[0027] The core network 10 and the private radio access network 11 are preferably part of a known cellular radio communication network such as GSM / GPRS or UMTS.

[0028] The remote access network 12 uses, in the embodiment of the invention, the PSTN, which can be accessed by the terminal 13 via a wireless interface, as a transport network. Such an interface may be based on bluetooth, infrared or an interface compatible with the DECT standard.

[0029] Remote access network 12 is preferably PSTN 122 for circuit switched data or PSTN for interconnection with Internet 123 for packet switched data. Terminal 13 may be connected to remote access network 12 via a lo...

Abstract

The invention relates to a method for connecting a terminal (13) over an access network (12), herein called remote access network, to a core part (10) of a radio communication network, said radio communication network comprising said core network (10) and a dedicated radio access network (11) different from said remote access network (12). <??>According to the invention, the method comprises the steps of: interfacing over a gateway (141, 142) said remote access network (12) to an entity (103, 104) of said core network (10), said entity (103, 104) being an element of said core network (10) at the interface between said core network (10) and another communication network; performing at said gateway (141, 142) a protocol stack translation for mapping protocols used in said remote access network (12) to protocols used in said entity (103, 104) of said core network (10); controlling the connection over said remote access network (12) by said core network (10).

Description

[0001] The present invention is based on the prior application EP 02 360 165.1, the content of which is hereby incorporated by reference. technical field [0002] The present invention relates to an access network, in particular to a method for connecting a terminal to the core part of a wireless communication network through the access network. Background technique [0003] Terminals are known in the art which support both the GSM (Global System for Digital Mobile Phones) and DECT protocol stacks. At home, the terminal can set up a telephone call over the air interface using the DECT standard, which is further routed in the PSTN (Public Switched Telephone Network). While on the move, the terminal will use the GSM network to establish a communication. Such terminals are provided for fixed / mobile integration, since the appropriate communication network is automatically selected according to the availability of communication over the DECT interface. [0004] This solution pr...
