Multistandard wireless network controller

Abstract

The wireless network controller includes following parts: at least one piece of network management control process board in use for starting and configuring wireless network controller, and sending / receiving management control data to / from network management system; multiple process board for processing calls in use for processing and controlling operations as well as processing signaling in high layer; multiple processing board of wireless protocol in use for processing wireless protocols, signaling stream and data stream in base layer; multiple process board of transport protocols in use for controlling and processing transport interface to carry out conversion between inner and outer data streams; multiple sub rack exchange units connected to a group of process boards and at least a rack exchange unit connected to a group of sub rack exchange units. The invention raises exchange capacity and integration density and is applicable to different system by running different software.

Description

technical field [0001] The present invention relates to a mobile communication system, in particular to a multi-standard wireless network controller used in the mobile communication system, its system structure and implementation scheme, etc. Background technique [0002] Fig. 1 is a schematic diagram of a wireless mobile communication system. As shown in FIG. 1 , the mobile communication system basically includes three parts, namely, a core network indicated by reference number 103 , a radio access network indicated by reference number 104 and user equipment indicated by reference number 105 . [0003] The core network 103 includes at least two domains, namely a circuit switching domain and a packet switching domain (not shown in FIG. )102 connection. [0004] The radio access network 104 includes at least one radio network controller (RNC) 1041 and a plurality of Node-Bs 1042 . The Node-B 1042 is used as a base station in the third generation mobile communication system...

AI Technical Summary

Problems solved by technology

First, the board area of ​​the existing wireless network controller is too small, the distance between the boards is too narrow, it is not easy to dissipate heat, the scalability is poor, the reliability is low, and the cost is high

Second, wireless network controllers constructed with specially designed boards take a long time to be put on the market and require more freight, which reduces the competitive advantage of telecom operators
