Multimode mobile communication terminal and working method thereof

Abstract

The invention relates to a multimode mobile communication terminal and a working method thereof, wherein a TD-LTE (Time Division-Long Term Evolution) terminal communication module in the multimode mobile communication terminal is closed when no available TD-LTE network exists, an application processing module is used for determining whether services formerly built on a GSM-GPRS (Global System for Mobile Communication-General Packet Radio Service) network or a TD-SCDMA network are automatically rebuilt on the TD-LTE network according to the kinds and the requirements of the services when the TD-LTE terminal communication module is started and registered in TD-LTE network; and when the TD-LTE terminal communication module is closed, the services formerly built on the TD-LTE network are automatically rebuilt on the GSM-GPRS network or the TD-SCDMA network. The invention preferably solves the problems of high standby power consumption and poor service continuity caused by insufficient coverage at the initial stage of building TD-LTE network, and provides good user experience.

Description

technical field [0001] The invention relates to a multi-mode mobile communication terminal, in particular to a multi-mode mobile communication terminal capable of working in GSM-GPRS / TD-SCDMA and TD-LTE and a working method thereof. Background technique [0002] LTE is a new generation of mobile communication technology. LTE adopts key technologies such as OFDM, MIMO, and adaptive scheduling to achieve a data rate level of uplink 50Mbps and downlink 100Mbps. Because LTE technology has the advantages of high bandwidth, high throughput and short delay, it is very suitable for high-speed data transmission. However, in terms of user experience and usage requirements, there are still some problems with TD-LTE mobile phones, which are difficult to solve in the short term: [0003] 1. Since LTE is essentially designed based on packet services, there is currently no good way to support voice services. Although the IMS-based VOIP (Voice overIP) service has also been introduced, it ...

AI Technical Summary

Problems solved by technology

[0006] 1. The multiple modes of the traditional multi-mode multi-standby terminal are always in the normal standby mode. When there are many holes in the coverage of the new LTE network, it will cause the LTE mode to continuously search the network frequently and run out of battery power in a short time;

[0007] 2. The different modes of the traditional multi-mode multi-standby terminal work independently, lack of interaction, and the service interrupted in one mode due to coverage cannot be automatically rebuilt in another mode, and the user experience is relatively poor
