Problems solved by technology

There are many problems with connecting client devices to the core network of the cellular operator, especially since the switching nodes of the core network are not particularly suitable for connecting a large number of RNCs
Furthermore, for a promising HGW concept, the cost of the gateway must be as low as possible, while the presence of RNC functionality does not contribute to the above goals

Embodiment Construction

[0021] refer to figure 1 , a conventional UMTS system comprises a core network (CN) 1 comprising interconnected switches called MSC for circuit switched services or SGSN for packet switched services. In a UMTS Terrestrial Radio Access Network (UTRAN) architecture, several Radio Network Controllers (RNCs) 2 are connected to CN switches. Each RNC 2 monitors several Base Transceiver Stations (BTS) 3 or "Node Bs" through an interface called Iub in the UMTS standard. BTSs are distributed in the area covered by the access network. Each BTS serves one or several cells where cellular service is available to the public.

[0022] According to the invention, a Home Gateway (HGW) 5 is added to the access network to define different types of cells. HGW 5 uses the same wireless interface as regular BTS 3. For convenience, a set of HGWs 5 may be allocated to a designated carrier frequency different from that used by the BTS 3 to avoid complication of the radio engineering of the common p...

Abstract

The access network for a cellular wireless communication system includes home gateways (5) placed in customer premises and providing wireless links to mobile stations, and a private operator network (20). The private operator network includes base station control units (22), security gateways (21) and a home gateway management server (26). The security gateway has a secure interface for establishing secure tunnels for communication with home gateways through a broadband public network (6). Each home gateway communicates via the security gateway with the home gateway management server of the private operator network to obtain an address of one of the base station control units allocated to the home gateway. The base transceiver station included in a home gateway interfaces with the allocated base station control unit via the private operator network and a secure tunnel with the security gateway.

Description

technical field [0001] The present invention relates to the deployment of residential gateways for cellular wireless networks. [0002] Its specific application to third generation (3G) cellular networks of the UMTS (Universal Mobile Telecommunications Service) type will be described below. It should however be realized that it is applicable to all types of digital cellular systems. Background technique [0003] It has been proposed (see eg US patent 6 615 035) to provide so-called Home Base Stations (HBS) to subscribers of cellular operators. This unit connects to the user's land telephone line and has a wireless interface similar to that of a cellular infrastructure. When a user uses a handheld device in his or her home, ie within range of the HBS, calls are established via landlines and the Public Switched Telephone Network (PSTN), rather than the cellular network. Mobility functionality between cells of HBS coverage and cellular infrastructure is not provided. [000...
