Abstract
A multiple access wireless communication system uses transmitter-receivers supported by remote signal processing devices. The down link transmission receives signals from the internet, PSTN, or other networks and assigns the signal to one of several shared, software configured, signal processing devices that processes, digitizes, and compresses, then forwards them to a thin client transmitter. The transmitter decompresses the received signals, and transmits to remote users using the appropriate wireless protocol. An uplink transmission includes: an antenna for receiving analog RF signals from remote users; an A/D converter; compressing the digital signals; and transporting the compressed digital signals to a remotely located, software configured, shared signal processing system. The shared remote signal processing system decompresses these signals; assigns the decompressed signal to one of several shared, software configurable signal processing devices that processes these signals and transmits the signals onwards via the internet, switched telephone, or other networks.
Description
Technical field
The present invention relates generally to radio communication.Especially, the present invention relates to for using the method and system of the multi-address radio communication system of being supported by long-range software configuration signal treatment facility.
Background technology
The conventional cellular network of using now relies on Fat Client (thick-client) mode to carry out the processing of network edge signal to audio call and digital call.Especially, for the calling from landline telephone (land-line), the local office of PSTN (PSTN) converts optical signalling to base band frequency (BBF) conventionally to be delivered to mobile switching centre (MSC).MSC is by handshaking to base station controller (BSC), and BSC passes the signal to a base station in a plurality of base stations (BTS) with radio frequency (RF) supervisory instruction.Then, BTS is used antenna that this signal downlink link is arrived to user.From user's calling up link, arrive the antenna of contiguous BTS.BTS is upstream sent to this calling in PSTN via BSC and MSC.
When processing calling from descending angle, BTS plays multiple effect conventionally.For example, BTS can be connected with the landline telephone speech line of BSC.BTS also can be combined into RF passage by a plurality of speech lines.More specifically, combine a plurality of base band circuits, and convert thereof into the radio frequency of expectation.As another example, BTS also can amplify RF passage and send it to long-distance user.
When processing calling from up angle, BTS can be configured to and receives RF passage, and this RF passage comprises a plurality of long-distance users' signal.BTS also can be by speech line and the RF receiving channel separation.More specifically, RF signal is to process handled signal by low noise amplifier, RF filter and numeral and/or Analog Baseband.Finally, BTS can be configured to by analog modem speech line is transferred to BSC.Because important call treatment is to carry out at the edge of network, this mode can be described as Fat Client normal form.The example of Fat Client normal form can be in U.S. Patent No. 4,901, and 307 find, and here the full content of this patent is incorporated to by reference herein.
Although Fat Client normal form is practical ways, its existent defect and inferior position.For example, during down link and uplink processing, BTS generally needs large disposal ability, and disposal ability is normally provided by comparatively expensive digital signal processor (DSP) and application-specific integrated circuit (ASIC).DSP is often special-purpose, and produces with limited amount.And these DSP generally do not allow the cross-application such as WiMax, GSM, CDMA or other agreement.As a result, need carrier wave to safeguard expensive independence and parallel equipment and network, to support these other agreements.
The another kind of mode that cellular call is processed is thin-client (thin-client) normal form.U.S. Patent No. 5,627,879 (" ' 879 patents ") have illustrated the example of thin-client normal form, here the full content of this patent are incorporated to by reference herein.In thin-client normal form, BTS is divided into two parts: antenna element (AU) and base station unit (BSU).Thin-client mode provides following advantage, that is, AU and wireless protocols (WiMax, CDMA, GSM etc.) are irrelevant.Yet, the problem of this mode is: the digitlization of RF signal has increased the bandwidth requirement of link between AU and BSU, and T-1 ' s, T-3s or microwave link that tradition is used are often inefficient, this need to use optical fiber, and optical fiber is not still all available everywhere.
In the described embodiment of ' 897 patents, decimation filter is set so that unwanted passage is filtered out from digital stream, make it possible to by such as T-1 line compared with the carrier wave of low velocity by the signal shift-in from antenna element with shift out base station unit.Although this embodiment has solved the problem of return bandwidth, it has brought again two other problems.First, the extra digit signal that AU place needs is processed and has been guaranteed that it is no longer thin-client.The second, as in Fat Client mode, AU is limited to again agreement.
