Granted with the priority, the performance of voice calls is not affected by VMS. A multicode scheme is used for VMS traffic to transmit on multiple spreading codes in parallel. The SIR constraints of voice and VMS calls are taken into account to identify the system capacity. By using a two-dimensional Markov model, the performance of the integrated system is evaluated. Under different system traffic loads, QoS-based system capacities are obtained and optimal coding schemes for VMS are specified. Finally, the effect of the VMS buffer size is discussed.<br \/>\n<span class=\"paper_subtitle\">KEYWORDS<\/span><br \/>\nVoice Message Service (VMS), CDMA, Markov model, soft handoff<\/p>\n","protected":false},"excerpt":{"rendered":"<p><a href=\"http:\/\/network.ee.tsinghua.edu.cn\/papers\/lius_VMScdma_ICCT2003.pdf\" target=\"_blank\"><img loading=\"lazy\" decoding=\"async\" class=\"alignleft size-full wp-image-117\" title=\"pdf\" src=\"https:\/\/network.ee.tsinghua.edu.cn\/niulab\/wp-content\/uploads\/2010\/08\/pdf.gif\" alt=\"\" width=\"95\" height=\"50\" \/><\/a>Song Liu, Zhisheng Niu, Dawei Huang, <span class=\"papertitle\">Performance Analysis of Voice Message Service in CDMA Cellular Systems<\/span>, <span class=\"papersource\">2003 International Conference on Communication Technology, pp.891-895, 9-11th, April 2003, Beijing, China.<\/span><\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_jetpack_memberships_contains_paid_content":false,"footnotes":""},"categories":[7],"tags":[99,36,23,18],"jetpack_sharing_enabled":true,"jetpack_featured_media_url":"","_links":{"self":[{"href":"https:\/\/network.ee.tsinghua.edu.cn\/niulab\/index.php?rest_route=\/wp\/v2\/posts\/252"}],"collection":[{"href":"https:\/\/network.ee.tsinghua.edu.cn\/niulab\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/network.ee.tsinghua.edu.cn\/niulab\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/network.ee.tsinghua.edu.cn\/niulab\/index.php?rest_route=\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/network.ee.tsinghua.edu.cn\/niulab\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=252"}],"version-history":[{"count":2,"href":"https:\/\/network.ee.tsinghua.edu.cn\/niulab\/index.php?rest_route=\/wp\/v2\/posts\/252\/revisions"}],"predecessor-version":[{"id":917,"href":"https:\/\/network.ee.tsinghua.edu.cn\/niulab\/index.php?rest_route=\/wp\/v2\/posts\/252\/revisions\/917"}],"wp:attachment":[{"href":"https:\/\/network.ee.tsinghua.edu.cn\/niulab\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=252"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/network.ee.tsinghua.edu.cn\/niulab\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=252"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/network.ee.tsinghua.edu.cn\/niulab\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=252"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
