Abstract

This invention relates to a cellular basestation, and in particular to a basestation for a cellular communications network, that can conveniently be used to provide a cellular service, for example within a home or office.

Claims

1. A base station with ciphering termination functionality, for use in a cellular communications network and an Internet protocol (IP) network, having:

a radio interface for communication with wireless communications devices by means of a wide area cellular wireless communications protocol, and having Access Stratum functionality comprising Radio Link Control/Medium Access Control functionality, wherein the Radio Link Control/Medium Access Control functionality allows the base station to terminate ciphering performed over the radio interface in order to be able to access data packets being transferred over the radio interface; and

an IP interface, for communication over an IP network via an IP gateway with a node of the cellular communications network, wherein the base station is configured to receive incoming data from a wireless communications device via the radio interface, the base station further configured to control packet data sessions and send outgoing data over a public broadband Internet connection to the node of the cellular communications network via the IP interface.

2. The basestation as claimed in claim 1, wherein the Access Stratum functionality comprises Radio Resource Management functionality.

3. The basestation as claimed in claim 1, being adapted to encrypt data for transmission to the cellular communications network.

4. The basestation as claimed in claim 3, being adapted to use IPSec for encryption of said data for transmission to the cellular communications network.

5. The basestation as claimed in claim 1, wherein the cellular wireless communications protocol is a wide area cellular wireless communications protocol.

6. A basestation with ciphering termination functionality, for use in a wide area cellular communications network and an Internet protocol (IP) network, comprising a Radio Access Network and a Core Network,

wherein the basestation has a radio interface, for communication with user equipment devices located in a cell associated with the basestation,

wherein the basestation has an Internet Protocol interface, for communication over an IP network via an IP gateway with a node of the cellular communications network, wherein the base station is configured to receive incoming data from a wireless communications device via the radio interface, the base station further configured to control packet data sessions and send outgoing data over a public broadband Internet connection to the node of the cellular communications network via the IP interface,

wherein the basestation has Access Stratum functionality comprising Radio Link Control/Medium Access Control functionality allowing the basestation to terminate ciphering of signals received over the radio interface in order to be able to access data packets transferred across said radio interface, and

wherein the basestation is adapted to encrypt data for transmission to the cellular communications network.

7. A method of operating a base station and radio resource management in a cellular communications network and an Internet protocol (IP) network, the method comprising:

receiving incoming data at the base station from a wireless communications device via a radio interface,

wherein the radio interface is configured for communication with wireless communications devices by means of a wide area cellular wireless communications protocol,

wherein the radio interface has Access Stratum functionality comprising Radio Link Control/Medium Access Control functionality;

using the Radio Link Control/Medium Access Control functionality to terminate ciphering performed over the radio interface in order to access data packets being transferred over the radio interface;

controlling packet data sessions of the data packets being transferred over the radio interface; and

sending outgoing data over a public broadband Internet connection to a node of the cellular communications network via an IP interface, the IP interface configured for communication over the IP network via an IP gateway with the node of the cellular communications network.
