Embodiment Construction

[0029] figure 1 A third generation wireless telephone network 1 established according to the present invention is shown. The radiotelephone network 1 has a primary radio access of the CDMA type on a primary radio channel 2 comprising two symmetrical links called the primary uplink 3 (uplink) and the primary downlink 4 ( downlink), both of which have eg 5MHz bandwidth. The radiotelephone network 1 also supports multi-carrier radio access on at least one link of a supplementary radio channel 6 to provide packet data transmission services.

[0030] The supplementary radio channel 6, eg having a bandwidth of 5 MHz, may be located within the radio frequency band allocated to third generation systems. These radios make up the 230MHz "core" band in the 1885÷2025MHz and 2210÷2200MHz portions of the spectrum. Optionally, the supplementary radio channel 6 may be located in an extended part of the aforementioned frequency band. In this case, for example the 800÷960MHz, 1700÷1885MHz a...

Abstract

The invention relates to a radio telephone network (1) which supports at least one link of a radio channel (6) to be used for a grouping data transmission service. The radio telephone network (1) comprises a plurality of network controllers (RNC), wherein each network controller (RNC) is connected to at least one radio base station (node B) for managing at least one macro cell (5a) through an interface Iub. The radio telephone network (1) further comprises at least one micro radio base station (micro node B1) which is connected to the network controller (RNC) through the interface Iub which connects the radio base station (node B) to the interface of the controller, wherein the type of the interface is as same as the interface Iub. The management for the micro radio base station (micro node B1) is merged into at least one micro cell (5b) in the at least one macro cell (5a). The multi-carrier radio access is preferably used as the access of the micro radio base station (micro node B1). The grouping data transmission service is supplied on the link of the radio channel (6) in the micro cell (5b). The multi-carrier radio access is preferably OFDM type.

Description

[0001] This application is a divisional application of the invention patent application with the application number 03826350.0, the application date is April 23, 2003, and the name is "wireless telephone network with multi-carrier packet data transmission". technical field [0002] The present invention relates generally to the field of radiotelephony, and more particularly to radiotelephone networks, such as third generation radiotelephone networks. The invention relates in particular to third generation wireless telephone networks with packet data transmission provided by multi-carrier techniques such as OFDM (Orthogonal Frequency Division Multiplexing). Background technique [0003] Known wireless telephone systems, such as GSM, are basically intended for voice communication. These systems use two symmetrical links, named downlink (from terrestrial base station to mobile station) and uplink (from mobile station to base station). [0004] Systems under development are als...
