The method and apparatus of the present invention are further described with reference to the accompanying drawings and the detailed description of the invention.
An embodiment of the present invention provides an antenna switching control method, as shown in fig. 1, the method includes:
step S100: the terminal acquires the shielding state of the main antenna.
Currently, the fourth generation mobile communication (4G) mainly employs two technologies: 1) circuit Switched Fallback (CSFB) technology, 2) LTE and GSM synchronous support (simutaneousmanddlte, SGLTE) technology/LTE and voice synchronous support (simutaneousvoiceandlte, SVLTE) technology; the CSFB technology is a single-card single-standby mode, and a terminal can only work in an LTE network or a 2G/3G network, for example, the terminal works in the LTE network and returns to the 2G/3G network to work in a fallback mode when a voice call comes; the SGLTE/SVLTE technology is a dual-card dual-standby mode, a terminal can work in an LTE network and a 2G/3G network at the same time, and under the dual-network mode, data services are transmitted through the LTE network, voice services are transmitted through the 2G/3G network, and mutual non-interference cooperative work is achieved.
Here, the main antenna and the diversity antenna are generally used as the transceiving antenna in the single-card single-standby mode, and the main antenna, the diversity antenna and the auxiliary antenna are generally used as the transceiving antenna in the dual-card dual-standby mode; in the single-card single-standby mode, the main antenna is used for providing a receiving and transmitting function of a 2G/3G or LTE network service and corresponds to a main receiving channel and a main transmitting channel; the diversity antenna is used for enhancing the receiving performance, generally has only receiving capability, and corresponds to a diversity receiving path, in terms of hardware, the main antenna and the diversity antenna in the single-card single-standby mode are respectively a set of hardware paths, and in order to ensure the radiation absorption rate (SAR) performance, the main antenna is generally located at the bottom of the rear side of the terminal, so that the diversity antenna is generally located at the top of the front side or the rear side of the terminal, as shown in fig. 2a, and is less harmful to the human body far away from the head of a user; in the dual card dual standby mode, the main antenna and the diversity antenna are used for receiving and transmitting one card, the secondary antenna is used for receiving and transmitting another card, and corresponds to the secondary receiving path and the secondary transmitting path, in terms of hardware, the main antenna and the diversity antenna in the dual card dual standby mode are one set of hardware paths, the secondary antenna is independent of the other set of hardware paths, the main antenna and the diversity antenna are usually located at the bottom of the rear side of the terminal, and the secondary antenna is usually located at the top of the front side or the rear side of the terminal, as shown in fig. 2 b.
Here, the shielding state of the main antenna is shielding or non-shielding, and the main antenna is usually in the shielding state due to the user holding the bottom of the rear side of the terminal.
Here, the terminal may obtain the shielding state of the main antenna according to a set time interval or an event triggering manner; the terminal can preset a time interval according to the actual situation, wherein the time interval is not specifically limited; the specific event triggering manner may be to trigger obtaining of the shielding state of the main antenna when it is detected that the user uses voice or data service.
Here, how to obtain the shielding state of the main antenna belongs to the prior art, and repeated descriptions are omitted.
Step S101: and controlling a main receiving channel and a main transmitting channel to switch the antennas according to the shielding state of the main antenna.
Specifically, when it is determined that the main antenna is in a shielding state, if a current service used by a user is a voice service, the main receiving path may be switched to a diversity antenna or an auxiliary antenna; or,
the main reception path and the main transmission path may be switched to the diversity antenna or the sub-antenna.
In the above embodiment of the present invention, the main receiving path and the main transmitting path are connected to the main antenna in an initial state, and when it is determined that the main antenna is in a shielded state, if the current service used by the user is a voice service, the main receiving path and the main transmitting path connected to the main antenna are switched to the diversity antenna or the auxiliary antenna, so as to avoid that the quality of the received and transmitted signal is affected when the main antenna is in the shielded state, thereby improving the receiving and transmitting performance of the voice service, and further improving the use experience of the user.
In the above embodiment of the present invention, if the terminal needs to ensure the SAR performance, when it is determined that the main antenna is in a shielded state, if the current service used by the user is a voice service, only the main receiving path connected to the main antenna is switched to the diversity antenna or the auxiliary antenna, and the main transmitting path connected to the main antenna is not switched, so that the main antenna far away from the head of the user is connected to the main transmitting path to ensure the SAR performance; the diversity antenna or the auxiliary antenna is connected with the main receiving channel to avoid the influence on the quality of the received signal when the main antenna is in a shielding state, so that the receiving performance of the voice service is improved, and the use experience of a user is further improved.
Specifically, when it is determined that the main antenna is in the shielded state, if the service currently used by the user is a data service, the main transmitting path and the main receiving path connected to the main antenna are switched to the diversity antenna or the auxiliary antenna, and at this time, because the service currently used by the user is a data service and the user is far away from the terminal, the SAR performance is not considered, and the main transmitting path and the main receiving path connected to the main antenna are switched to the diversity antenna or the auxiliary antenna, so that the quality of the transmission and reception signals is prevented from being affected when the main antenna is in the shielded state, and the transmission and reception performance of the data service is improved.
It should be noted that, in the single card single standby mode, since the diversity antenna is located at the top of the front side or the rear side of the terminal, when the main antenna is in a shielding state, the main receiving path and the main transmitting path connected to the main antenna are switched to the diversity antenna; in the dual-card dual-standby mode, because the main antenna and the diversity antenna are one set of hardware path and the auxiliary antenna is another set of hardware path independently, the main antenna and the diversity antenna are usually located at the bottom of the rear side of the terminal, and the auxiliary antenna is usually located at the top of the front side or the rear side of the terminal, when the main antenna is in a shielding state, the main receiving path and the main transmitting path connected with the main antenna are switched to the auxiliary antenna.
Specifically, if it is determined that the main antenna is in an unshielded state in the initial state, the main receiving path and the main transmitting path connected to the main antenna are not switched, and the processing flow is ended; if the main receiving path and the main transmitting path have been switched to the diversity antenna or the secondary antenna, the main receiving path and the main transmitting path may be switched back to the main antenna when it is determined that the main antenna is changed from the shielded state to the unshielded state.
In order to more clearly illustrate the embodiments of the present invention, the data exchange flow in the embodiments of the present invention is described in detail below with specific embodiments.
Example one
When the terminal applies the CSFB technique, it is in the single-card single-standby mode, and 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, and if the main antenna 2 is in the shielding state, the radio frequency switch is controlled to access the main antenna 2 to the transmitting path 02 according to the GSM/TD-SCDMA transmitting time slot, and the diversity antenna 1 is accessed to the GSM/TD-SCDMA receiving path 01 according to the receiving time slot, as shown in fig. 3; therefore, the SAR performance can be ensured, and the receiving performance of the GSM/TD-SCDMA voice service can be improved.
Example two
When the terminal applies the CSFB technique, it is in the single-card single-standby mode, and at this time, the service currently used by the user is a Wideband Code Division Multiple Access (WCDMA)/CDMA 1x voice service, and if the main antenna 2 is in the shielding state, the radio frequency switch is controlled to access the main antenna 2 to the transmitting path 02 and the diversity antenna 1 to the receiving path 01, as shown in fig. 4; therefore, the SAR performance can be ensured, and the receiving performance of the WCDMA/CDMA1x voice service can be improved.
EXAMPLE III
When the terminal applies the CSFB technology, the terminal is in a single-card single-standby mode, at this time, a service currently used by a user is an enhanced data rate GSM evolution (EDGE)/TD-SCDMA data service, and if the main antenna 2 is in a shielding state, the radio frequency switch is controlled to access the diversity antenna 1 to the main transmitting channel 02 according to an EDGE/TD-SCDMA transmitting time slot and to the EDGE/TD-SCDMA receiving channel 01 according to a receiving time slot. Since the service currently used by the user is a data service and the user is far away from the terminal, the diversity antenna 1 is accessed to the main receiving path 01 or the main transmitting path 02 without considering the SAR performance, as shown in fig. 5, so as to improve the transceiving performance of the EDGE/TD-SCDMA data service.
Example four
When the terminal applies the CSFB technology, the terminal is in a single-card single-standby mode, the service currently used by a user is the WCDMA/CDMAEvDo data service, and if the main antenna 2 is in a shielding state, the radio frequency switch is controlled to access the diversity antenna 1 to the main channel 04 through the duplexer. Since the service currently used by the user is a data service and the user is far away from the terminal, the diversity antenna 1 is connected to the main channel 04 through the duplexer without considering the SAR performance, as shown in fig. 6a, so as to improve the transceiving performance of the WCDMA/cdma ev do data service; in the fourth embodiment, for WCDMA/cdma evdo, it is necessary to use frequency to distinguish reception and transmission, so a duplexer is needed to combine transmission and reception into one path, but the use of the duplexer not only wastes hardware resources, but also occupies terminal motherboard resources, so the rf switch can be controlled to access the main antenna 2 to the main transmission path 02 and access the diversity antenna 1 to the main reception path 01, as shown in fig. 6b, so that two antennas are used to perform reception and transmission respectively, which not only saves hardware resources, but also improves the reception performance of WCDMA/cdma evdo data services.
EXAMPLE five
When the terminal applies the CSFB technique, the terminal is in a single-card single-standby mode, and at this time, a service currently used by a user is a frequency division duplex long-term evolution (FDD-LTE) data service, if the main antenna 2 is in a shielding state, the radio frequency switch is controlled to access the main antenna 2 to the diversity path 03, and the diversity antenna 1 is accessed to the main path 04 through the duplexer, as shown in fig. 7, so as to improve the transmission performance of the FDD-LTE data service.
EXAMPLE six
When the terminal applies the CSFB technique, the terminal is in a single-card single-standby mode, and at this time, a service currently used by a user is a time division duplex long term evolution (TDD-LTE) data service, and if the main antenna 2 is in a shielding state, the radio frequency switch is controlled to access the main antenna 2 to the diversity path 03, the diversity antenna 1 to the main transmitting path 02 according to a transmitting time slot, and to the main receiving path 01 according to a receiving time slot, as shown in fig. 8, so as to improve the transmitting performance of the TDD-LTE data service.
EXAMPLE seven
When the terminal applies the LTE and GSM synchronous support technology, the terminal is in a dual-card dual-standby mode, at this time, a service currently used by a user is an SGLTE data service, and if the main antenna 2 is in a shielded state, the radio frequency switch is controlled to access the main antenna 2 to the auxiliary transmitting path 06 or the auxiliary receiving path 05, and the auxiliary antenna 3 is accessed to the main path 04 through the duplexer, as shown in fig. 9, so as to improve the transceiving performance of the SGLTE data service.
Example eight
When the terminal applies the LTE and GSM synchronous support technology, the terminal is in a dual-card dual-standby mode, at this time, the service currently used by the user is an SVLTE data service, and if the main antenna 2 is in a shielded state, the radio frequency switch is controlled to access the main antenna 2 to the auxiliary antenna path 07 through the duplexer, and the auxiliary antenna 3 is accessed to the main path 04 through the duplexer, as shown in fig. 10, so as to improve the transceiving performance of the SVLTE data service.
In the seventh embodiment and the eighth embodiment, the auxiliary antenna 3 is connected to the main channel 04 through the duplexer, but the main antenna 2 still needs to be connected to the system to serve as the auxiliary antenna 3 and take charge of the transceiving function of the auxiliary channel (RFIC2), so that the dual-card dual-pass can be realized, but at this time, the auxiliary channel usually has no service data.
