Embodiment 1

[0056] Embodiment 1, a kind of base station built-in Modem to data modulation method, this method is the technical scheme that SOC with Modem function is built in base station, see Figure 4 ,include:

[0057] Step F1, the built-in SOC-based Modem in the base station completes its own management configuration, and the configuration management may include: the configuration management of the modulated data and the configuration management of the demodulated data by the built-in Modem of the base station.

[0058] In Embodiment 1 of the present invention, when the base station has a built-in SOC-based Modem, the central processing unit CPU (Central Processing Unit) on the SOC inside the base station communicates with the base station management station to realize the configuration of the base station internal SOC-based Modem by the base station management station management, see Figure 5 As shown, it specifically includes: the base station management station sends management c...

Embodiment 2

[0069] Embodiment two, a kind of base station built-in Modem demodulates the method to data, and this method also belongs to the technical scheme that SOC with Modem function is built in base station, see Figure 8 ,include:

[0070] In step R1, the built-in SOC-based Modem in the base station completes its own management configuration.

[0071] Wherein, usually, the built-in Modem of the base station performs configuration management on modulation data and configuration management on demodulation data at the same time. Therefore, it can be considered that this step is the same as step F1 in the first embodiment. You can refer to the configuration management method based on the Modem on the SOC built in the base station in step F1.

[0072] Step R2, the base station based on the Modem on the SOC receives the analog signal sent by the BSC, according to the result obtained by the configuration management of the demodulated data, the analog signal is demodulated on the DSL laye...

Embodiment 3

[0082] Embodiment three, a kind of modulating method of base station built-in Modem to data, this method belongs to the technical scheme that the embedded chip with Modem function is built in base station, see Figure 9 ,include:

[0083] Step S1, the base station completes the configuration management of the embedded chip-based Modem built in the base station. The configuration management may include: configuration management of the base station for data modulation and configuration management for data demodulation.

[0084] Wherein, since the embedded chip realizing the Modem function usually cannot complete the configuration management of the Modem, other modules in the base station and the embedded chip jointly complete the configuration management of the built-in Modem based on the embedded chip.

[0085] The other modules in the base station may be to add a transmission module to the existing base station to realize the transmission of configuration management informati...

Abstract

One embodiment of the invention provides a data modulating method for a built-in Modem of a base station, a data demodulating method, a base station and a communication system, wherein, the data modulating method comprises that the built-in Modem of the base station configures an asynchronous transmission mode ATM layer and a digital subscriber line DSL layer according to the received configuration management information; the data are carried out the treatment of the ATM layer and the DSL layer according to the configured result. The remote management problem of the Modem is solved through building the Modem in the base station and configuring and managing the Modem by a base station management platform in the embodiment of the invention; the Modem can synchronize with the clock information of the base station without external clock lines; the Modem built in the base station can be charged easily in the base station, thereby the current supply demand of the station is simplified; a Modem module is taken as a functional module of a base station product.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a transmission method of a built-in modem in a base station, a base station and a communication system. Background technique [0002] With the rapid development of wireless broadband services, the wireless transmission bearer network based on the Internet Protocol IP (Internet Protocol) transmission mode has become more and more popular. Base stations can be connected to the IP bearer network through various broadband access technologies. DSL (Digital Subscriber Line) last mile fixed broadband access technology is very suitable for IP access of indoor base transceiver station BTS (Base Transceiver Station, referred to as base station) equipment due to its low cost and easy availability. The base station is connected to the BSC through the Ethernet interface provided by the DSL. The current implementation plan deploys DSL terminal equipment on the BTS side, such as a DSL mo...
