Page 4邻区规划的意义?为了保持通信的连续性,需要给覆盖重叠的小区添加相应邻区。邻区与切换有着密切的关系。?如果在网络整体规划时频点、邻区、扰码规划得不好,则会造成整个网络建成或扩容后某些性能指标不符合要求。Page 5Copyright ? 2006 Huawei Technologies Co., Ltd. All rights reserved. Page 5TD-SCDMA邻区配置个数??For idle mode cell reselection purposes, the UE shall be capable of monitoring:?32 intra-frequency cells (including serving cell), ?32 inter-frequency cells, including TDD mode cells on maximum 3additional TDD carriers, ?32 GSM cells distributed on up to 32 GSM carriers,as indicated in cell information lists sent in system information (BCCH).?终端的异频测量能力仅支持3个异频,会使得在实际现网中配置的频点个数超过4个时,小区选择、重选和切换时不能选择到最好的小区。终端能够最大支持测量额外8个TDD频点。Page 6Copyright ? 2006 Huawei Technologies Co., Ltd.
