Cell reselection method

Abstract

The invention provides a cell reselection method, which comprises that: one or more virtual neighbor cells are configured in a macro cell, and are configured with a frequency point and scrambling code pair respectively; a femto-cell adjacent to the macro cell sets a frequency point and a scrambling code of the main carrier frequency of the femto-cell to be the same as those of the virtual neighbor cell of the macro cell; when the signal intensity of a main common control physical channel of the femto-cell meets reselection requirements, a user terminal resident in the macro cell performs reselection from the macro cell to the femto-cell; and the user terminal performing the reselection to the femto-cell initiates location area updating to a network side, and the network side selects the frequency point with the lowest interference as a main frequency point of the femto-cell according to the location area updating. By the cell reselection method, the reselection of the user terminal from the outdoor macro cell to the femto-cell can be realized effectively.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a cell reselection method. Background technique [0002] With the rapid development of mobile communication technology, the continuous improvement of wireless access rate and the wide application of broadband access network and wireless network, the types of mobile services have also expanded from the initial simple voice and short message services to various , Rich and colorful value-added mobile data industry. The vast number of users also hope to be able to access the network through handheld wireless devices at high speed anytime, anywhere, so as to enjoy increasingly rich network resources and various high-speed, convenient, and low-cost wireless data services. Data show that the indoor environment is often the place where users use the most concentrated wireless cellular services. For example, indoor voice services can even account for 70% of the overall voice...

Problems solved by technology

However, when it is necessary to reselect from an outdoor macro cell to a Femto cell, due to the specific network structure in practical applications, the number of Femto cells around a macro cell may be relatively large, for example, there are dozens of Femto cells, and The capacity of the neighboring cell list in the macro cell is limited, and the information of other neighboring macro cells needs to be stored. Therefore, in general, it is impossible for the macro cell to add all neighboring Femto cells to the neighboring cell list, making it difficult to ensure that users Handover of terminal (UE) from outdoor macro cell to Femto cell
