改善分組預(yù)約多址協(xié)議中話音業(yè)務(wù)性能的一種方法
AN IMPROVEMENT METHOD FOR PRMA S VOICE SERVICE
-
摘要: 本文在分析分組預(yù)約多址(PRMA)協(xié)議的基礎(chǔ)上,從用戶角度和實(shí)際通信情況考慮,提出了基于補(bǔ)償性參數(shù)作為系統(tǒng)的性能參數(shù),并采用適當(dāng)加大用戶再次競(jìng)爭(zhēng)信道的允許概率來提高PRMA系統(tǒng)中話音業(yè)務(wù)性能的方法(VP-PRMA),從計(jì)算機(jī)仿真的結(jié)果看,該方法對(duì)提高PRMA系統(tǒng)中話音業(yè)務(wù)的性能確有幫助。

Abstract: A method (VP-PRMA) based on the users demand to improve the performance of voice service in PRMA system is proposed. In the paper, a new system measurement based on relative penalty factor is used. After the analysis of PRMA, the new method, using variable contend probability according to the actual condition, is presented. According to the simulation, the proposed method improves the voice performance as expectated. -
