Description
本發明係關於一種行動通信跨系統交遞鄰細胞之選擇方法，特別是指一種利用細胞天線型式、細胞天線角度、細胞交遞量以及細胞與細胞之間的距離，篩選出適合作為跨系統(Inter-system)交遞之鄰細胞，以達到提升跨系統交遞成功比率之選擇方法。The present invention relates to a method for selecting a mobile communication cross-system to deliver adjacent cells, in particular to a method for using a cell antenna type, a cell antenna angle, a cell turnover amount, and a cell-to-cell distance to select a suitable cross-system ( Inter-system) delivers neighboring cells to achieve a method of increasing the probability of successful cross-system delivery.
以往執行一種行動通信系統之跨系統交遞鄰細胞選擇工作，需要維運人員分別蒐集兩個系統之網路資訊後，據以自行設定該跨系統交遞鄰細胞；不僅費時費力，而且容易遺漏適合作為交遞之鄰細胞；同時，當發生跨系統間之交遞失敗率偏高時，由於先前並無依據一套標準流程來選擇鄰細胞，因此無法檢視在選擇該鄰細胞過程中是否有出現盲點，藉此以找出問題發生原因所在。In the past, the implementation of a cross-system handover neighbor cell selection operation of a mobile communication system requires the maintenance personnel to separately collect the network information of the two systems, and then set the cross-system to deliver the adjacent cells according to the self; it is not only time-consuming and laborious, but also easy to miss. It is suitable as a neighboring cell for delivery; at the same time, when the cross-system handover failure rate is high, since the adjacent cells are not selected according to a standard process, it is impossible to check whether there is any selection in the process of selecting the adjacent cells. A blind spot appears to identify the cause of the problem.
由此可見，上述習用方式仍有諸多缺失，實非一良善之設計者，而亟待加以改良。It can be seen that there are still many shortcomings in the above-mentioned methods of use, which is not a good designer, but needs to be improved.
本案發明人鑑於上述習用方式所衍生的各項缺點，乃亟思加以改良創新，並經多年苦心孤詣潛心研究後，終於成功研發完成本件一種行動通信跨系統交遞鄰細胞之選擇方法。In view of the shortcomings derived from the above-mentioned conventional methods, the inventor of the present invention has improved and innovated, and after years of painstaking research, he finally succeeded in researching and developing a method for selecting a mobile communication system to deliver adjacent cells.
達成上述發明目的之跨系統交遞鄰細胞的選擇方法，係利用細胞天線型式、細胞天線角度、細胞交遞量以及細胞與細胞之間的距離，來選擇出適合作為跨系統交遞之鄰細胞；其中包括對四類不同特性之細胞選擇其跨系統鄰細胞；(一)原系統之細胞之天線型式為全向性(Omni)之細胞，選擇距離 較近之跨系統細胞作其鄰細胞；(二)原系統之細胞之天線型式為指向性(Directional)，並與跨系統之細胞共站，且共站之兩系統扇形細胞天線方位角誤差小者；先將共站之該跨系統細胞列為該鄰細胞，再採用共站該跨系統細胞之同系統(Intra-system)交遞細胞中交遞量較高之細胞係為該鄰細胞；若篩選出之鄰細胞數量仍不足時，再輔以篩選原系統細胞天線涵蓋之扇形區域內距離越近之該跨系統細胞係為該鄰細胞；此依距離所篩選之該跨系統細胞，其天線角度須指向該原系統細胞天線涵蓋扇形區域之互補位置；(三)原系統之細胞之天線型式為指向性，並與該跨系統之細胞共站，但共站之兩系統扇形細胞天線方位角誤差大者；先將共站之該跨系統細胞列為該鄰細胞，再取該原系統天線涵蓋之扇形區域內距離最近之該跨系統細胞係為該鄰細胞；此依距離所篩選之該跨系統細胞，其天線角度須指向該原系統細胞天線涵蓋扇形區域之互補位置；(四)該原系統之細胞的天線型式為指向性，並與該跨系統之細胞非共站；取該原系統扇形細胞天線涵蓋之扇形區域內距離最近的該跨系統細胞為鄰細胞；此依距離所篩選之該跨系統細胞，其天線角度須指向該原系統細胞天線涵蓋扇形區域的互補位置；上述四類特性涵蓋所有行動通信系統細胞，依此方法可完整選擇出跨系統交遞之鄰細胞。The method for selecting a cross-system delivery neighboring cell that achieves the above object of the invention uses a cell antenna pattern, a cell antenna angle, a cell turnover amount, and a cell-to-cell distance to select an adjacent cell suitable for cross-system delivery. It includes selecting four cross-system neighboring cells for cells of different characteristics; (1) the antenna type of the cells of the original system is Omni cells, and the distance is selected.
