Embodiment
In the following description, in order to make the reader understand the application better many ins and outs have been proposed.But, persons of ordinary skill in the art may appreciate that even without these ins and outs with based on the many variations and the modification of following each execution mode, also can realize each claim of the application technical scheme required for protection.
For making the purpose, technical solutions and advantages of the present invention clearer, embodiments of the present invention are described in further detail below in conjunction with accompanying drawing.
First embodiment of the invention relates to a kind of differential mode dual-standby mobile terminal.In the present embodiment, differential mode dual-standby mobile terminal comprises: the first standard single mode chip, the radio frequency processing that is used to carry out the transmitting-receiving of first standard signal.Dual-mode chip is used for the radio frequency processing that the transmitting-receiving of second standard signal or first standard signal receive.Baseband processing chip is used for the signal of the first standard single mode chip and dual-mode chip transmitting-receiving is carried out Base-Band Processing.
When the first standard single mode chip is received and dispatched the signal of business of first standard, if terminal need be carried out the second standard business simultaneously, then dual-mode chip is is only received and dispatched second standard signal, if terminal need not to carry out the second standard business simultaneously, then dual-mode chip receives the diversity signal of the business of first standard.
Owing to include high-speed data service such as HSDPA etc. among the WCDMA, increase downstream signal diversity reception branch road and can significantly improve the downstream signal receptivity, therefore, be WCDMA with first standard in the present embodiment, second standard is that GSM is that example describes.
As shown in Figure 2, dispose in differential mode dual-standby mobile terminal: the WCDMA single mode chip is used to carry out the radio frequency processing of WCDMA signal transmitting and receiving; The dual-mode chip that GSM transmitting-receiving, WCDMA receive is used for the radio frequency processing that GSM signal transmitting and receiving or WCDMA signal receive.Baseband processing chip is used for the signal of WCDMA single mode chip and dual-mode chip transmitting-receiving is carried out Base-Band Processing.WCDMA single mode chip and dual-mode chip are separately to there being an antenna.Describe for convenient, can be collectively referred to as Radio Frequency Subsystem A by the antenna that the WCDMA single mode chip is corresponding with it, the antenna that dual-mode chip is corresponding with it is collectively referred to as Radio Frequency Subsystem B.
Radio Frequency Subsystem A and Radio Frequency Subsystem B can work alone, and Radio Frequency Subsystem B synchronization can only carry out GSM transmitting-receiving work or WCDMA diversity reception.Specifically, when portable terminal only carried out GSM professional, Radio Frequency Subsystem A did not work, and B works alone by Radio Frequency Subsystem, and Radio Frequency Subsystem B only carries out the transmitting-receiving of GSM signal.When portable terminal carries out the business of WCDMA such as HSDPA, portable terminal carries out the signal transmitting and receiving of HSDPA business by Radio Frequency Subsystem A, and, if this moment, terminal need be carried out gsm service simultaneously, then dual-mode chip is is only received and dispatched the GSM signal, if this moment, terminal did not need to carry out simultaneously gsm service, then dual-mode chip receives the diversity signal of HSDPA business, to improve the down-link reception performance of HSDPA.
This shows, only adopted two radio frequency chips and two antennas in the present embodiment, can accomplish that anomalous mode is two to treat.By GSM transmitting-receiving, WCDMA are received and be combined in the dual-mode chip, dual-mode chip receives the WCDMA diversity signal of HSDPA business when having only HSDPA professional, to guarantee the down-link reception performance of HSDPA.When though professional and gsm service is concurrent at HSDPA, dual-mode chip can only be carried out the GSM transmitting-receiving, can't receive the WCDMA diversity signal of HSDPA business, down-link reception performance to HSDPA influences to some extent, but consider generally not have real-time data communication needs when making a call GSM, so the situation that this situation occurs is less.And, GSM is under the situation of holding state when carrying out the HSDPA high-speed data communication, the GSM subsystem is in the very little operating state of duty ratio, mainly be to carry out paging, work such as measurement in idle time, are switched Radio Frequency Subsystem B to WCDMA diversity reception state by baseband chip at the GSM subsystem, can in most of times, improve the down-link reception performance of HSDPA.That is to say, present embodiment has only been sacrificed the performance under the insensitive part scene of user experience, but reduced a chips and an antenna, reduced the cost of differential mode dual-standby mobile terminal, also dwindled the volume of portable terminal because of the minimizing of antenna number effectively.
What deserves to be mentioned is that the dual-mode chip in the present embodiment can adopt the integrated chip that possesses the transmitting-receiving of first standard signal and the second standard signal transmission-receiving function to realize.Because in present prior art, produced the integrated chip of the signal transmitting and receiving function that possesses two kinds of standards, therefore, can realize dual-mode chip among the application by existing product, simple, be convenient to realize.
In addition, be appreciated that, the first standard single mode chip also can be accomplished in several ways, as realizing by the integrated chip that possesses the transmitting-receiving of first standard signal and the second standard signal transmission-receiving function, or realize, or realize by the integrated chip that possesses the transmitting-receiving of first standard signal and other standard signal transmission-receiving functions by the chip that only possesses the first standard signal transmission-receiving function.But no matter realize, when work, all only need use the first standard signal transmission-receiving function, therefore still can be described as the first standard single mode chip in essence by which kind of mode.
