Embodiment 1

[0028] The present invention provides a network configuration method, such as figure 1 As shown, the main steps are as follows:

[0029] Step 101, setting up a private network cell in the expressway area, and the private network cell is covered by a dedicated frequency point area;

[0030] In step 102, the private network cell and the public network cell configure a neighbor relationship in the station area of ​​the expressway.

[0031] Utilizing the above-mentioned method for paging a terminal, the present invention also provides a chain network system implementing the method, such as figure 2 As shown, it includes: a private network base station 1, which is used to cover the expressway area with a dedicated frequency point; a neighbor cell setting unit 2, which is used to configure the neighbor cell relationship between adjacent cells.

[0032] Such as image 3 As shown, the invention of the method is based on the geographical characteristics of the expressway, and the p...

Embodiment 2

[0045] Embodiment 2 is based on Embodiment 1, and solves the problem of network coverage and adjacent cell setting in the "X-shaped" area where expressway 1 and ordinary road 4 intersect but are not connected. Such as Figure 5As shown, the public network cell 2 covers ordinary roads, and the private network cell 3 covers expressways. In the intersecting area, public network cell 2 and private network cell 3 are not configured with neighbor relationship. When the terminal crosses the intersection, the terminal on the ordinary road will only switch between the two public network cells 2, and the terminal on the expressway will only switch between the two private network cells 3. It effectively ensures that the terminal in high-speed movement will not be handed over to the public network cell 2 along the line, reduces the frequency of cell change, and improves the access quality of wireless communication.

Embodiment 3

[0047] This embodiment 3 is based on the embodiment 1, and solves the problem of network coverage and adjacent cell setting in the intersecting area of ​​the expressway 1 and the ordinary road 4 . Such as Figure 6 As shown, the public network cell 2 covers ordinary roads, and the private network cell 3 covers expressways. In addition, a private network transitional cell 5 is configured on the ordinary road as a transitional cell of the private network cell 3. Because the mobile terminal equipment on the expressway 1 is faster, and the same-frequency handover is easier to trigger than the different-frequency handover, if the network transition cell 5 is not set, when the terminal in the private network cell 3 enters the public network cell 2, it is easy Residing in the private network cell 3, that is, being cut into another private network cell 3, but not being cut into the public network cell 2. In addition, direct inter-frequency switching may lead to untimely switching or ...

Abstract

The invention discloses a method for configuring a wireless network. According to the method, private network cells are set in an express way region, and the private network cells are covered by a dedicated frequency point region; a neighbouring region relationship is configured for the private network cells and public network cells in the site region of an express way; the neighbouring region relationship between the private network cells and the public network cells is not configured in an express way region without an intersection. According to the method, the defects of frequent cell replacement, low access success rate and conversation quality declining of high-speed mobile terminal equipment in the existing network are solved. By virtue of the method, the replacement frequency of the equipment among the different cells can be reduced, the switching and reselection paths of the equipment in case of high-speed movement are ensured well, and the communication quality is improved. The applications of a radio resource management algorithm, a switching and reselection policy and network parameter values dedicated to high-speed scenes are promoted, thus the quality of the whole network is improved better.

Description

technical field [0001] The invention relates to a configuration method and system of a mobile communication network, in particular to a wireless network coverage and network configuration method in a high-speed mobile environment, and a system using the method. Background technique [0002] Modern mobile communication systems are usually established on the basis of cellular networking. User terminals are connected to network equipment through wireless channels in a cell; and as the terminal moves, handover and inter-area Local network automatic roaming function. With the emergence of high-speed transportation equipment such as high-speed rail and maglev, the terminal equipment carried by users will move rapidly, and the cell changes frequently, which affects the access success rate, data service flow, and paging success rate. If it is not overcome, the seamless coverage of the high-speed rail cannot be guaranteed, causing the call quality of the user terminal to decline or ...
