Method and equipment for selecting cell access for terminal equipment

Abstract

The invention discloses a method for selecting cell access for terminal equipment, which comprises the following steps: comparing the traveling speed of the terminal equipment and a threshold value; when the traveling speed of the terminal equipment is not smaller than the threshold value, selecting a private network cell to access the terminal equipment; and when the traveling speed of the terminal equipment is smaller than the threshold value, selecting a public network cell to access the terminal equipment. The invention also discloses network equipment for selecting the cell access for the terminal equipment. The communication quality of the terminal equipment can be improved by adopting the invention.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and device for selecting a cell for terminal equipment to access. Background technique [0002] In order to meet the mobile communication requirements of high-speed scenarios such as high-speed railways and maglevs, the networking mode of the access network can usually adopt a unified public network networking mode, or a networking mode combining private networks and public networks. The unified public network networking method utilizes the original base station site and base station equipment along the high-speed scene, and basically does not need to add new equipment to achieve the coverage of high-speed mobile lines, and at the same time, it can meet the coverage of surrounding areas. The network combination of private network and public network will cover the base station equipment, transmission, antenna feeder system and other wireless equipment along...

Problems solved by technology

[0004] 1. In order to meet the coverage of high-speed mobile lines, a large overlapping coverage area needs to be ensured between base stations, and the station distance is required to be relatively small, while the original base station distance is relatively small Large, difficult to meet the coverage requirements of high-speed mobile lines

[0005] 2. Subsequent network expansion and adjustment, in the planning process of frequency, scrambling code, LA / RA, engineering parameters, etc. of the original base station, high-speed mobile lines must be taken into account at the same time The coverage of the coverage and the coverage of the surrounding area will be mutually restrained, making planning and optimization more difficult

[0006]3. In order to adapt to the high-speed mobile scene, the setting of the wireless parameters will be different from the conventional ones, and it is difficult to take into account the high-speed mobile scene and the surrounding ordinary scenes at the same time

[0010] If the cell level of the private network is set to low priority and the cell level of the public network is set to high priority, although the user terminal in the surrounding low-speed scene can be Communication processes such as power-on, cell reselection, and call establishment will not occupy the wireless resources of the private network cell, but will cause high-speed terminals to attach to the public network; otherwise, set the private network cell level to high priority, and the public network cell If the level is set to a low priority, it will cause low-speed terminals to attach to the private network; since there is no neighbor relationship between the private network and the public network covering the surrounding low-speed scenes, once the terminal is attached to the public network or private network, it will be more difficult. It is difficult to switch between the private network and the public network through mobility management processes such as cell reselection or handover. , it will always occupy public network cell resources, and will always occupy public network cell resources during cell reselection, call establishment, and communication, resulting in reduced call quality or dropped calls
