Abstract

A method of obtaining information for use in a smart antenna system is provided. The method includes monitoring an interface between a base station controller and a base station transceiver to receive signaling information being communicated via the interface. The method further includes extracting from the signaling information a subset of the signaling information operable to be used as input for selecting one or more of a plurality of beams for wireless communications.

Claims

1. An antenna apparatus, comprising:

a smart antenna unit, comprising;

a signaling information monitoring system configured for receiving base station control information communicated via an interface between a base station controller and a base station transceiver, comprising;

a monitoring unit configured for passively monitoring the base station control information; and

an extracting unit configured for extracting relevant signaling information from the base station control information, wherein the relevant signaling information is relevant for determining a beam selection and/or verifying the beam selection.

2. The antenna apparatus of claim 1, wherein the base station control information comprises information with regard to one or more traffic channels.

3. The antenna apparatus of claim 1, wherein the monitoring unit comprises:

a signal splitter configured for splitting an interface signal communicated between the base station controller and the base station transceiver into a first path connecting the base station controller and the base station transceiver and a second path transmitted to the signaling information monitoring system;

a first decoding module configured for receiving signals communicated via the second path and configured for a first level of decoding of signals received via the second path; and

a second decoding module configured for decoding data received from the first decoding module.

4. The antenna apparatus of claim 3, wherein the first decoding module is an E1/T1 decoding module.

5. The antenna apparatus of claim 3, wherein the second decoding module is a Layer 2 Link Access Procedure on the D-Channel decoder.

6. The antenna apparatus of claim 3, wherein the signal splitter is configured to connect the signaling information monitoring system and the interface using a high impedance signal.

7. The antenna apparatus of claim 3, wherein the signal splitter is configured to connect the signaling information monitoring system and the interface without amplifying the signal being communicated via the second path.

8. The antenna apparatus of claim 3, wherein the extracting unit comprises:

a first filtering module configured for filtering the data received from the second decoding module;

a third decoding module configured for decoding the data received from the first filtering module;

a second filtering module configured for filtering and/or decoding data received from the third decoding module; and

a pre-processing module configured for organizing the data received from the second filtering module.

9. The antenna apparatus of claim 8, wherein the first filtering module is a Link Access Procedure on the D-Channel filtering module.

10. The antenna apparatus of claim 8, wherein the third decoding module is a Layer 3 Base Transceiver Station Management decoding module.
