Embodiment Construction

[0027] The basic idea of ​​the present invention is: through the transformation of PPP technology and the processing to base transceiver station (BTS) hardware, make the PPP technology that can only be used for point-to-point connection realize point-to-multipoint connection, thereby realize base station controller in The existing chain structure E1 transmission line connects multiple BTSs through a PPP. This method is implemented in downlink service transmission, all base stations can share limited bandwidth resources, and greatly reduces downlink transmission delay.

[0028] One of the present invention, the method for realizing the bandwidth sharing of the base station system in the chain topology structure

[0029] Subject: From the hardware structure, the base station controller can establish connection with all BTSs on the E1 line. From the point of view of the base station controller, for an E1, there is only one PPP connection, and all BTSs on the chain topology will ...

Abstract

The invention relates to bandwidth sharing method and base station signal receiving sending platform in on-chain topological structure of base station system. The method includes the following steps: connecting E1 transmission line with many BTS by PPP while transmitting descending data; the BTS includes one switching module used to exchange BSC or upward BTS descending data to operation maintain platform and signaling processing platform, and exchange the descending data to next BTS descending chain. The invention can make all base stations can shear limit bandwidth resource in descending service transmitting, greatly reduce descending transmitting delay, increase transmitting efficiency, improve the complexity for realizing chain transmission structure in IP network.

Description

technical field [0001] The present invention relates to the second generation (2G) / third generation (3G) base station system (BSS), especially refers to the last mile transmission technology (Last mile transmission technology) in the access network, that is, to realize the base station system in the chain type Bandwidth sharing method in topology and its base transceiver station (BTS). Background technique [0002] As we all know, compared with the traditional TDM (Time Division Multiplexing) network, the current IP network is very mature and has low operation and maintenance costs. Therefore, the integration of various transmission networks into IP networks is an inevitable trend in the telecommunications industry. [0003] Transplant GSM (Global System for Mobile Communications) wireless network to IP transmission network, from wireless access to core network access, all network devices will realize the interconnection between network elements through IP technology.
