Baseband processing method and apparatus

Abstract

The present invention discloses a baseband processing method and apparatus. According to the method, when DSP resources are requested, a DSP resource scheduling module allocates a DSP with low resource occupancy according to DSP resource occupation conditions in an L1 / L2 layer processing module; and a switching module transmits a data packet to the corresponding the DSP through a physical port corresponding to an allocated DSP identification code in a business facade according to the allocated DSP identification code and preset route mapping relations, wherein the route mapping relations at least comprise corresponding relations between DSP identification codes and physical ports. Thus, DSP resources can be reasonably allocated according the DSP resource occupation conditions, and the limitations of card boards can be broken through, and the reliability and operation and maintenance efficiency of equipment is improved; and the route mapping relations are built according to the DSP identification codes and the physical ports, and the forwarding of the data packet can be completed through the corresponding physical port according to the route mapping relations, and generated time delay is smaller compared with conventional Ethernet switching or sRIO (Serial Rapid I / O) switching.

Description

technical field [0001] The present invention relates to the technical field of communications, in particular to a baseband processing method and device. Background technique [0002] At present, it is more and more important to improve the reliability of wireless communication equipment, and taking protection measures for important functions or components is one of the important means to improve the reliability of wireless communication equipment. At present, when designing wireless network equipment architecture, baseband (L1 / L2 / L3 layer) design methods usually include the following: [0003] Option 1: Mainly for small base stations such as macro / pico / femtocells with low equipment capacity and small-scale wireless coverage, generally adopt an integrated design with a high degree of integration, and the wireless protocol L1 / L2 / L3 layers are concentrated on one physical board card for implementation. And considering factors such as cost and device size, for application scen...

Problems solved by technology

[0012] 1. Although the first solution is low in cost and easy to implement, it can only provide port protection. The baseband processing part is a single node, which cannot be backed up, and the reliability of the equipment is low. Therefore, it is only suitable for macro / pico / Femto cells and other small base station products

[0013] 2. Compared with scheme 1, although scheme 2 has substantially improved the processing capacity and reliability, it can meet the operator's requirements for high reliability of carrier-grade equipment, but because this scheme adopts IP packet switching, it is only suitable for data services Broadband wireless devices with low requirements for end-to-end voice service delay (no more than 400ms), such as 3G wireless networks that operators have deployed in large numbers

Although this solution adopts the data packet transmission protocol, which can make the end-to-end service delay of 4G wireless network equipment meet the requirement of less than 5ms specified by 3GPP, it still cannot meet the expectations of the next generation wireless network (such as 5G wireless communication system): On the basis of existing network technology (4G), the end-to-end delay is shortened by 5-10 times.
