Problems solved by technology

The strategy of this reselection scheme is simple, but the problem is that if the PLMN of the found TDD network is not RPLMN or EPLMN, it will still reside in any cell under TDD, and will eventually return to the GSM network
This phenomenon of repeated switching of mobile terminals between two base stations not only increases the time for searching the network, but also cannot provide users with better network quality

Embodiment Construction

[0043] In order to make the above-mentioned and other objects, features and advantages of the present invention more obvious and understandable, with the accompanying drawings, the detailed description is as follows:

[0044] see image 3, which shows a schematic flow diagram of cross-access technology network reselection according to the first embodiment of the present invention, which shows the process of the terminal crossing from the first network GSM network to the second network TD-SCDMA network. In step S101, the mobile terminal camps on a GSM cell. In step S102, it is judged whether the timer for regularly searching for TDD cells has expired, and if the judgment result is yes, then go to step S103. In step S103, the access layer of the GSM network requests the physical layer to search a cell of the TDD network, and the obtained search result includes the cell ID and received signal code power of the cell. In step S104, the GSM physical layer reports the searched TDD ...

Abstract

The invention discloses a method and a device for improving the reselection success rate when a terminal across accesses a technical network, which are used for a terminal to access a second network from a first network. In the method and the device, after the terminal acquires the signal intensity of a cell of the second network from the first network, the terminal continues reading main information blocks of the cell, and if a public land mobile network is judged to be a registered public land mobile network or an equivalent public land mobile network, the second network is reselected. The method and the device can enable users to feel the optimal network quality and improve the success rate of normal service.

Description

technical field [0001] The present invention relates to a mobile communication technology, in particular to a method and a device capable of improving the success rate of terminal reselection across access technology networks. Background technique [0002] Due to the development of the second-generation mobile communication technology and the third-generation mobile communication technology, dual-mode mobile terminals supporting the two standards are appearing day by day. For these mobile terminals, whether to save power is an important indicator for judging their performance. Reselection across access technology networks is a cause of power consumption of dual-mode mobile phones to a certain extent. Therefore, improving the success rate of reselection across access technology networks is of great significance to both users and manufacturers. [0003] There are many kinds of mobile communication terminals commonly used, such as GSM / GPRS, GSM / CDMA, GSM / WCDMA, and GSM / TD-SCDM...
