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

Use is by the multi-address radio communication system of the transmitter-receiver of the signal handling equipment support of long-range software arrangements

Technical field

The present invention relates generally to radio communication.Especially, the present invention relates to be used to use the method and system of the multi-address radio communication system of supporting by long-range software arrangements signal handling equipment.

Background technology

The conventional cellular network of using relies on Fat Client (thick-client) mode that audio call and digital call are carried out the network edge signal processing now.Especially, for the calling from landline telephone (land-line), the local office of PSTN (PSTN) converts optical signalling to base band frequency (BBF) usually so that be delivered to mobile switching centre (MSC).To base station controller (BSC), BSC passes the signal to a base station in a plurality of base stations (BTS) with radio frequency (RF) supervisory instruction to MSC with handshaking.Then, BTS uses antenna that this signal downlink link is arrived the user.Arrive the antenna of contiguous BTS from user's calling up link.BTS should call out via BSC and MSC and upstream be sent among the PSTN.

When handling from descending angle when calling out, BTS plays multiple effect usually.For example, BTS can be connected with the landline telephone speech line of BSC.BTS also can be combined into the RF passage with a plurality of speech lines.More specifically, make up a plurality of base band circuits, and convert thereof into the radio frequency of expectation.As another example, BTS also can amplify the RF passage and send it to the long-distance user.

When handling from up angle when calling out, BTS can be configured to and receives the RF passage, and this RF passage comprises a plurality of long-distance users' signal.BTS also can be with speech line and the RF that is received channel separation.More specifically, the RF signal is to handle handled signal by low noise amplifier, RF filter and numeral and/or Analog Baseband.At last, 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 the Fat Client normal form.The example of Fat Client normal form can be in U.S. Patent No. 4,901, and 307 find, and incorporates the full content of this patent into this paper by reference here.

Although the Fat Client normal form is practical ways, it exists shortcoming and inferior position.For example, during down link and uplink processing, BTS generally needs big disposal ability, and disposal ability is normally provided by comparatively expensive digital signal processor (DSP) and application-specific integrated circuit (ASIC).DSP often is 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 handled 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, incorporate the full content of this patent into this paper by reference here.In the thin-client normal form, BTS is divided into two parts: antenna element (AU) and base station unit (BSU).The 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 the BSU, and T-1 ' s, T-3s or microwave link that tradition is used often are inefficient, and this need use optical fiber, and optical fiber still is not all available everywhere.

In the described embodiment of ' 897 patents, decimation filter is set so that unwanted passage is filtered out from digital stream, makes it possible to by such as the T-1 line, will and shifting out base station unit from the signal shift-in of antenna element than the carrier wave of low velocity.Though this embodiment has solved the problem of return bandwidth, it has brought two other problems again.At first, the extra digit signal processing of AU place need has guaranteed that it no longer is a thin-client.The second, as in the Fat Client mode, AU is subject to agreement again.
