Method, terminal and network element for cell reselection according to cell service features

Abstract

The invention provides a method, terminal and network element for cell reselection according to cell service features. The method comprises the following steps of: carrying out statistics on the service incomes of a first service and a second service of a 3G cell, and dynamically adjusting the RAT cell measurement trigger threshold of the 3G cell and the level of a 2G neighbor cell according to the statistical result; making the terminal to tend to stay in the 2G cell when the number of users using the first service is greater than that of users using the second service in the 3G cell; and otherwise tending to stay in the 3G cell. Therefore, the optimization of a reselection mechanism is realized in the cell reselection process according to the service type, so that the second service is carried on the 3G network as much as possible and the voice service is carried on the GSM network as much as possible. The traditional perception of users is maintained, and meanwhile, the resource of the 3G network is fully utilized. Moreover, by adopting the method, the terminal and the network terminal, unnecessary 2G / 3G network searching can also be reduced, and the electric energy of the terminal is saved.

Description

Technical field [0001] The present invention relates to the field of mobile communication technology, in particular to a method, terminal and network element for cell reselection according to cell service characteristics. Background technique [0002] The third generation of mobile communications (3G), such as Time-Division Synchronization Code Division Multiple Access (TD-SCDMA) technology, provides 3G users with a wealth of service types, such as video calls and video messages , High-speed Internet, video surveillance and mobile TV and many other services. Although TD-SCDMA products (such as network equipment, terminal equipment, test equipment, etc.) are becoming more mature and commercialized, there is still a certain gap between the service quality that users expect. Through a large-scale network test, it is found that the service quality of the TD-SCDMA network is higher than that of the second-generation mobile communication (2G) system, such as the GSM system, due to the...

Problems solved by technology

[0008] In the 2G / 3G reselection mechanism of the prior art, the relevant parameter settings are uniform for any scene (such as dense urban areas, ordinary urban areas, and suburbs), and there are obvious deficiencies in rationality and accuracy; and, the prior art The reselection mechanism does not take into account the basic requirements of 3G users for services, that is, while keeping the network service quality of 2G voice services unchanged (including continuity, voice quality, etc.), they also expect to obtain high-quality 3G special services, such as video Telephone, high-speed Internet access, etc., so the 2G / 3G reselection mechanism in the prior art cannot optimize the reselection according to the service type
