Embodiment Construction

[0040] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0041] A network processor is a multi-CPU chip that supports multi-threading and parallel processing. The method and device of the present invention utilize the characteristics of the network processor to separate the A11 signaling processing process from the A10 media processing process, and respectively process the A11 signaling by the xscale core of the network processor, and process it by the micro-engine of the network processor A10 media, the two parts work independently, and because the network processor contains multiple micro-engines, it can realize the serial processing of A10 media, and each micro-engine completes a part of A10 media processing respectively. In this way, the processing speed can be greatly improved, the processing capacity of the single board can reach more than 400Mbps, and the process is clear and easy to be modula...

Abstract

This invention discloses a device and method for realizing CDMA network A10 / A11 interface in communication field. Said device includes xscale core and plurality of microengine, said xscale core complete the process to A11 signaling, negotiation message of PPP link, link charging message and delivery address message, writing link information in memory in table format for engine use, microengine completing A10 media process, multiengine completing A10 media serialization process, completing universal route package, PPP protocol process and media stream transmission. Said invention can saves cost, simplifies system and controls complexity.

Description

technical field [0001] The invention relates to a CDMA (Code Division Multiple Access) system in the communication field, in particular to a method for realizing the A10 / A11 interface of CDMA1X and CDMA2000 with a network processor. Background technique [0002] The A10 / A11 interface of CDMA1X and CDMA2000 involves two functional entities, PCF and PDSN, and its protocol levels are as follows: [0003] A11 signaling UDP IP link layer physical layer [0004] A11 interface protocol stack [0005] A10 media PPP GRE IP link layer physical layer [0006] A10 interface protocol stack [0007] There are two key points in the protocol to realize the A10 / A11 interface: 1) Support large traffic: it should reach 400Mbps in CDMA1X network, and 800Mbps in CDMA2000 network; 2) GRE (Generic Routing Encapsulation) protocol processing: GRE The payload is a PPP packet, and the PPP packet has been...
