Embodiment Construction

[0051] The invention will be further described below in conjunction with the accompanying drawings and examples.

[0052] Step 1, this method introduces the "activity" attribute parameter of the base station of the cellular network cell, and sets the "activity" parameter to four different attribute values, which are respectively the real-time switching number of the user in the network cell, the network cell The number of active users in the network cell, the number of real-time services in the network cell and the number of network session reconnection requests, these parameters can be obtained from the cellular base station equipment in the network cell, so the "activity" attribute parameter of each cellular network base station has four attribute values, which constitute the data matrix of the "activity" parameter.

[0053] Step 2, standardize the data matrix. Using translational standard deviation transformation and translational range transformation to process matrix ele...

Abstract

The invention discloses a physical cell identification distribution method based on fuzzy hierarchical clustering, and belongs to the field of communication networks. In order to solve the quality problem of network service communication in a user dense area, the invention provides a physical cell identification method based on fuzzy hierarchical clustering based on the activeness attribute of a cellular network base station. According to the invention, an "activeness" attribute concept of a cellular cell base station is introduced; solving the similarity of different cellular cell base stations by adopting an Euclidean distance method; A fuzzy hierarchical clustering algorithm in pattern recognition is adopted, so that allocation and multiplexing of physical cell recognition (PCI) are carried out on a cellular cell base station group with relatively high degree of activity preferentially. According to the method, the network service quality (Quality of Service, QoS) of the user and the distribution efficiency of the PCI are effectively improved. The invention discloses a physical cell identification and distribution method for a cellular network cell base station.

Description

technical field [0001] The present invention introduces the attribute concept of "activity degree" of cell base stations, adopts the Euclidean distance method to solve the similarity of different cell cell base stations, and adopts the fuzzy hierarchical clustering algorithm in pattern recognition to realize the priority of "activity degree" "Higher cell base station groups perform physical cell identification (Physical Cell Identification, PCI) allocation and multiplexing. The method effectively improves the user's network service quality (Quality of Service, QoS) and PCI allocation efficiency. A method for distributing physical cell identification of a cellular network cell base station belongs to the field of communication networks. Background technique [0002] Thanks to the continuous development of information technology and the increasing popularity of intelligent mobile terminal equipment, the global mobile data traffic has increased by an astonishing 4,000 times in...
