Problems solved by technology

[0005] The technical problem to be solved by the present invention is to propose a practical solution for the "variable speed terminal" users existing in the system, so as to solve the problem that the system issues frequent inter-layer switching commands due to frequent changes in the speed of such user terminals. Causes waste of system resources and affects communication quality

specific Embodiment approach

[0023] It can be seen from Figure 2 that the HCS layered cell system consists of the area covered by communication satellites and four layers of macro cells, micro cells, and pico cells. Among them, the area covered by communication satellites is set as the highest-level service cell, which is mainly used to serve fast mobile terminals (such as high-speed car and ship users) and variable-speed mobile terminals. The macro cell is the second-level service cell, mainly for faster Mobile terminals (such as regular or slow-moving motor vehicles) serve, microcells mainly serve slower mobile terminals (such as non-motorized vehicles), and picocells mainly serve slow mobile terminals (pedestrian users, etc.).

[0024] As shown in Figure 1, the call terminal moves from point A to point C along the dotted line. At position A within the coverage of the cell BS1, since the base station Ba can provide users with good communication quality, the mobile terminal is only provided by the base st...

Abstract

The invention discloses a method of classification rule and the switching management of HCS system terminal, relating to the mobile communication technique. The terminals of present laminated section system only consider the speed and the number of layers when in classification and switching. The invention divides the mobile terminals in conversation into the rapid mobile terminal, the slow mobile terminal and the variable speed mobile terminal according to the moving condition of mobile terminals; and selects the relative service section according to aforementioned types of mobile terminals while the laminated section system at least comprises two layers and the variable speed mobile terminal is fixed in the service section of highest layer. With said invention, the switching times coursed by the variation of mobile terminal speed can be reduced to improve the communication quality and the stability of system.

Description

technical field [0001] The invention relates to the mobile communication technology, especially the handover management method of the mobile terminal in the HCS (Hierarchical Cell Structure) system. Background technique [0002] Handover is the most important means of radio link control from the large-area system to the cellular system in mobile communication. It can maintain the continuity of calls when the mobile station MS passes through different cells, reduce the call drop rate, and provide better communication quality. [0003] The realization of the handover process requires a large amount of signaling to interact between the terminal and the network, and the magnitude of the signaling load will directly affect the communication quality of the system, especially in the hierarchical cell system, as shown in Figure 2, the cell layering brings The allocation and switching of terminals between layers is solved. At present, terminals in the hierarchical cell system only ...
