Problems solved by technology

[0004] The existing technical solutions have their own pertinence, and the purpose is to improve the system's transceiver performance. No matter how the switch is switched, the core is to select a good performance antenna for access. However, the existing technical solutions do not take into account the rear side of the user's handheld terminal. The impact of the bottom on the main antenna, if the main antenna is covered by the user, the performance of the main antenna will drop by about 10 times, which will reduce the performance of voice service / data service transmission and reception

Embodiment 1

[0060] When the CSFB technology is applied to the terminal, it is in the single-card single-standby mode. At this time, the service currently used by the user is Global System for Mobile Communication (GSM) / Time Division-Synchronous Code Division Multiple Access (TD-SCDMA) voice service. Antenna 2 is in the shaded state, then control the radio frequency switch to connect the main antenna 2 to the transmission path 02 according to the GSM / TD-SCDMA transmission time slot, and connect the diversity antenna 1 to the GSM / TD-SCDMA reception path 01 according to the reception time slot, Such as image 3 Shown; In this way, not only can the SAR performance be guaranteed, but also the receiving performance of the GSM / TD-SCDMA voice service can be improved.

Embodiment 2

[0062] When the terminal applies CSFB technology, it is in single card single standby mode. At this time, the user's current service is Wideband Code Division Multiple Access (WCDMA) / CDMA1x voice service. If the main antenna 2 is in the shaded state, control the radio frequency switch to switch the main antenna 2 is connected to the transmission path 02, and the diversity antenna 1 is connected to the reception path 01, such as Figure 4 Shown; In this way, not only can the SAR performance be guaranteed, but also the receiving performance of the WCDMA / CDMA1x voice service can be improved.

Embodiment 3

[0064] When the terminal applies CSFB technology, it is in the single card single standby mode. At this time, the user's current service is Enhanced Data Rate for GSME evolution (EDGE) / TD-SCDMA data service. If the main antenna 2 is in the shaded state, the radio frequency is controlled The switch connects the diversity antenna 1 to the main transmission path 02 according to the EDGE / TD-SCDMA transmission time slot, and connects to the EDGE / TD-SCDMA reception path 01 according to the reception time slot. Since the service currently used by the user is a data service, and the user is far away from the terminal, it is not necessary to consider the SAR performance, and the diversity antenna 1 is connected to the main receiving channel 01 or the main transmitting channel 02, such as Figure 5 Shown, in order to improve the sending and receiving performance of EDGE / TD-SCDMA data business.

Abstract

The invention discloses an antenna switching control method, comprising the steps of acquiring the shielding state of a main antenna; and controlling a main receiving channel and a main transmitting channel to perform antenna switching according to the shielding state of the main antenna. The invention also discloses a terminal at the same time.

Description

technical field [0001] The present invention relates to radio frequency technology in the field of wireless communication, in particular to an antenna switching control method and a terminal. Background technique [0002] The existing antenna switching scheme is mainly a sharing method. Since antennas of different standards are close in frequency bands, techniques such as diversity or Multiple-Input Multiple-Output (MIMO) can be used to switch antennas of different standards. [0003] In the process of realizing the present invention, the inventor found that the existing antenna switching scheme has at least the following defects: [0004] The existing technical solutions have their own pertinence, and the purpose is to improve the system's transceiver performance. No matter how the switch is switched, the core is to select a good performance antenna for access. However, the existing technical solutions do not take into account the rear side of the user's handheld terminal. ...
