Data processing method of mobile terminal, and mobile terminal using same

Abstract

The invention discloses a data processing method of a mobile terminal, and the mobile terminal using same. The data processing method comprises the steps of transmitting and receiving data by a main RF unit on a main carrier; receiving data by an auxiliary RF unit on an auxiliary carrier on condition that a voice service is idle; and when the voice service is in an activated state, disconnecting the auxiliary RF unit with the auxiliary carrier and receiving and transmitting voice information on a voice channel. According to the data processing method of the mobile terminal and the mobile terminal thereof, two RF units of the terminal respectively receive and transmit information on a long term evolution (LTE) main carrier and an LTE auxiliary carrier; and in a voice service state, one RF unit is used for LTE data transmission, and the RF unit is used for the voice service. The data processing method of the mobile terminal and the mobile terminal thereof have advantages of realizing multi-carrier aggregation and improving data performance.

Description

technical field [0001] The present invention relates to the technical field of mobile terminals, in particular to a data processing method for a mobile terminal and the mobile terminal. Background technique [0002] The Long Term Evolution Advanced (LTE-A) system or LTE system is more and more widely used. In order to support a wider system bandwidth, such as 300M, multiple LTE carriers are aggregated and allocated to terminals in the LTE-A system. Carrier aggregation refers to the aggregation of two or more LTE carrier units to achieve greater transmission bandwidth. The use of carrier aggregation technology not only improves the utilization rate of scattered spectrum in the wireless frequency band, but also increases the peak rate of the network. The terminal can receive and send data on one or more carriers at the same time according to its capabilities. At present, the solution for carrying voice services over LTE is still immature. Terminals mainly perform voice servic...

AI Technical Summary

Problems solved by technology

At present, the solution for carrying voice services over LTE is still immature. Terminals mainly perform voice services through the circuit domain. The dual-transmission and dual-reception terminal solution supports voice and data services independently by configuring two RF chips. This type of terminal supports Carrier aggregation needs to add a radio frequency chip, but the baseband chip does not support three radio frequency chips concurrently. Therefore, it is difficult for the existing dual-transmission and dual-reception LTE terminals to effectively use the bandwidth for data transmission through carrier aggregation, which reduces the user experience.
