Abstract
Data are transmitted between a core network (CN) and at least one access system (BSS) of a GSM based access system type via an Iu interface (Iu-I/F). Also, the present invention aims to provide accordingly adapted network elements. By virtue of the present invention, substantial savings concerning resources can be obtained by supporting data formats of GSM coded speech on the open, i.e., not network operator proprietary, Iu interface according to UMTS/3rd generation specifications. Thus, GSM transcoders and 3rd generation transcoders as well as GSM base station controllers and 3rd generation radio network controllers can be integrated, so that the same hardware resources can be used for both systems, i.e., for GSM as well as for 3rd generation.

A transmission method for transmission of data in a telecommunication network,
- said network comprising a core network (CN) and an access network (AN),
- with said access network (AN) comprising
- at least one access system (RAN, BSS) of a GSM based access system type;
- wherein data are transmitted between said core network (CN) and said at least one access system (BSS) of a GSM based access system type of said access network (AN) via an Iu interface (Iu-I/F) wherein each of said at least one access systems (RAN, BSS) comprises at least one transceiver device (BS) and an associated transceiver control device (RNC/BSC), and wherein data are transmitted within each of said access systems (RAN, BSS) via an Iub and/or an Iur interface in a frame format which is the same as the one adopted for said Iu interface (Iu-IF).
A telecommunication network, comprising
- a core network (CN) and an access network (AN),
- with said access network (AN) comprising
- at least one access system (RAN, BSS) of a GSM based access system type;
- wherein said core network (CN) is connected to said at least one access system (RAN, BSS) of a GSM based access system type of said access network (AN) via an Iu interface (Iu-I/F) wherein each of said at least one access systems (RAN, BSS) comprises at least one transceiver device (BS) and an associated transceiver control device (RNC/BSC), and wherein data are transmitted within each of said access systems (RAN, BSS) via an mb and/or an Iur interface in a frame format which is the same as the one adopted for said Iu interface (Iu-IF).
