基于纠缠度计算的量子移动信令相邻小区越区切换策略及仿真

信令是任何通信系统必不可少的重要组成部分,量子移动通信也不例外.然而,关于量子移动通信信令在相邻小区越区切换过程中的切换策略问题的研究迄今尚未展开.随着移动用户位置的改变,用户与基站间的纠缠度不断变化.本文提出了基于纠缠度计算的量子信令在相邻小区的越区切换策略.首先定义了信令纠缠度与距离的关系,然后研究了用户位置改变所导致用户与基站之间信令纠缠度的变化情况,提出了基于纠缠度阈值计算的切换算法.仿真结果表明,本文所提出的信令切换策略可靠性高,能够在各基站之间实现平稳切换.因此,本研究对于构造量子移动通信网络的信令系统及其标准的制定具有极为重要的技术支撑作用.

The Handover Strategy of Quantum Mobile Signaling Based on Entanglement Degree Computing in Adjacent Cells and Simulation

Signaling is an important part to the communication system, as well as quantum mobile communication. However, the handover strategy to quantum mobile communication signaling in adjacent cells has been researched. Quantum entanglement is the basis of the future quantum mobile communication. With the change of the position of mobile users, the entanglement degree between users and base station changes constantly. A handover strategy based on entanglement degree calculation quantum signaling in adjacent cells is proposed. Firstly, the relationship between signaling entanglement degree and distance is defined. Secondly, changes of signaling entanglement degree in adjacent cells is studied due to the change of the position of users, and a handover algorithm based on the threshold value of entanglement degree is proposed. The simulation results show that the proposed signaling handover strategy can obtain high reliability and realize smooth handover between base stations. Therefore this research will play an extremely important technical support role and standards set in constructing the signaling system quantum mobile communication network.
