TD-SCDMA/GSM融合组网共LAC研究
摘要
本文提出TD-SCDMA/GSM共LAC组网方案
缩短终端进行系统间重选的时延
改善用户"呼叫不可达"时延。并且通过优化配置
提升TD-SCDMA系统寻呼能力
以保障共LAC方案的可行性。实测结果表明
在乒乓重选的极端场景下
寻呼成功率从40%提升到100%
基本消除"呼叫不可达"现象。并且
TD系统的寻呼能力达到250TMSI/s
消除了寻呼瓶颈。
Abstract
This article proposes a schema of combining TD-SCDMA/GSM network with common LAC
which shortens greatly the inter-RAT reselection delay without decreasing TD-SCDMA paging capacity. The test result demonstrates paging success ratio is increased from 40% to 100%
and paging capacity is increased to 250 TMSI/s
which eliminates the "calling unreachable" effectively.
