Embodiment Construction

[0032] Take the railway station under the TD-SCDMA system as an example, such as figure 2 As shown, the traffic volume of the waiting room of the railway station is larger than that of the surrounding communities, resulting in unbalanced loads between the waiting room and the surrounding external network. Therefore, it is an urgent problem to be solved to balance the load of adjacent communities and improve the utilization of network resources. The structure of the network after simplification is as follows image 3 As shown, the central cell has a large traffic volume and belongs to a high-load area, and the surrounding cells have a small traffic volume and belongs to a low-load cell. The ratio of the traffic volume of the central cell to all traffic volumes in the system is defined as the load imbalance of the system. When the degree of balance is greater than or equal to 0.15, the system is unbalanced.

[0033] In order to realize user access and switching in a load-unbal...

Abstract

The invention discloses a method for user access and switching in a wireless network with an unbalance load, which is particularly suitable for use in networks with unbalance loads, such as railway stations and department stores. The method comprises: 1, judging if a current network is in an unbalance load state through a wireless network controller; 2, if the system is in an unbalance load state, regulating the coverage of each cell by dynamically regulating the pilot power of the cell according to an load condition of cells to balance the load of the cells, or if the system is in a balance load state, adopting the conventional switching method; 3, if the load of the system is balanced, allowing a mobile stations to select an optimal main cell for enabling the system to obtain an optimal transmission rate; and 4, allowing the mobile station to perform access and switching in queue on the basis of the priority of preserved channels. The method can balance the loads of neighboring cells and therefore relieve the serious switching queuing condition of cells of large service loads and a high system blockage rate condition and improve resource utilization rate.

Description

【Technical field】 [0001] The invention belongs to the technical field of mobile communication, in particular to a method for user access and switching under the condition of unbalanced load between adjacent cells in a mobile communication network, and is mainly applied in the field of mobile communication. 【Background technique】 [0002] For the cellular mobile communication system of the third generation mobile communication system (TD-SCDMA: Time Division-Synchronous Code Division Multiple Access), during a call, as the mobile station (MS: Mobile Station) moves, it is necessary to change the current serving cell switching operation. Cell handover is initiated by the network. Generally, the signal strength and signal quality of the current serving cell and neighboring cells are obtained according to the measurement report reported by the MS, and then the handover operation is triggered by a certain handover judgment method. An excellent handover control method can provide ...
