Embodiment Construction
[0026] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0027] The embodiment of the present invention adopts the motion process of particles to simulate the motion process of the mobile station. The particles used are characteristic particles and general particles with charge vectors. The so-called charge vectors are vectors composed of multiple charges. The charge vector carried by the characteristic particle is a finite-dimensional vector with a component of +1 and other components of 0, which is used to describe a common habitual trajectory of a user group, which represents a gregarious characteristic; the general particle corresponds to For a mobile station (mobile node) in the simulation, the charge vector carried by it is a finite-dimensional vector with at least one component being n...

The invention discloses a method for simulating movement of mobile station by movement of particles, which pertains to mobile communication technology. The method includes: initializing simulation area, setting movement rules for particular particle and common particle, starting simulation procedure; calculating a new location of particular particle after a simulation period according to current state of moving and corresponding moving rule; after moving to a new location, common particle and particular particle determine whether to update their moving state according to their new location. The invention simulates movement of mobile station by movement of particles, is characterized by simplicity in realization, flexibility in configuration and authenticity, and exhibits stochastic characteristic of mobile unit's movement, individualized area characteristic and gregariousness tendency characteristic.
Description
technical field [0001] The invention relates to the technical field of mobile communication, in particular to a method for simulating the motion process of a mobile station by using particle motion. Background technique [0002] In order to completely analyze and simulate a new mobile communication system and the corresponding protocol signaling system, it is essential to establish a mobile station motion model to accurately describe the motion characteristics of the mobile station in the real operating environment of the system. A valuable new system, scheme or design, even if there is a slight improvement, must be double-verified by theoretical analysis and close to real simulation. Only under this premise can the newly designed mobile communication system and The feasibility and credibility of the protocol signaling system, so the establishment of the motion model is extremely important. [0003] At present, the research methods of mobile station motion in mobile communi...
