Embodiment Construction

[0068] With the rapid development of mobile communication systems, multi-mode and multi-standby mobile terminals that can not only enjoy the high-speed services of the third-generation mobile communication system, but also take advantage of the wide coverage of the second-generation mobile communication system are launched for new users. The application has become more and more extensive. In the single baseband implementation scheme, when the multi-mode terminal card of the mobile terminal undergoes cross-network cell reselection, how to ensure that the mobile terminal does not lose paging during the reselection process or when reselection fails becomes a key to improving the paging success rate .

[0069] In view of this problem, the inventor proposes a method for cell reselection of a multi-mode multi-standby mobile terminal, which can reduce the problem of paging loss during the reselection process, such as figure 1 shown, including:

[0070] Step S1: The first network mo...

Abstract

The invention discloses a mobile terminal and a cell reselection method. The cell reselection method comprises steps: a first network module of the mobile terminal sends a cell reselection request to a second network module; the second network module receives the cell reselection request and sends a decoding request to a baseband module of the mobile terminal; the baseband module receives the decoding request, carries out decoding on synchronous messages and broadcast messages of a target cell and feeds the decoding result to the second network module; during any of the above process, if the baseband module receives a paging message of a first terminal card or a second terminal card, the reselection process is stopped; and based on the decoding result, the first terminal card carries out resident of the target cell. According to the technical scheme, paging missing of the mobile terminal during the cell reselection process can be reduced.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a mobile terminal and a cell reselection method. Background technique [0002] At present, the third-generation mobile communication system is attracting more and more users' attention and use because of its more efficient spectrum efficiency, higher service quality and confidentiality performance, and higher service rate. However, the second-generation mobile communication system has wider network coverage and stable call effects, and still has its unique advantages. For example, when a user needs to use high-speed data services, he can choose the third-generation mobile communication system, and when the user goes to a relatively remote area, he can choose the second-generation communication system. In order to meet the application requirements of users in different scenarios, a multi-mode multi-standby mobile terminal that can support both the third-generation mo...
